Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a current collector for a railway vehicle, and more particularly to a current collector with a control suitable for a high-speed railway vehicle.

[0002]

2. Description of the Related Art In a current collector for a high-speed train (hereinafter referred to as a vehicle) such as a bullet train, a sliding plate of the current collector is pressed against the overhead wire with a predetermined force in order to prevent separation of the current collector from the overhead wire. It is necessary. Therefore, EP06
The following current collectors have been proposed by 05214A2. This device is provided with a sliding plate that contacts the overhead wire, a wing-shaped cover that supports the overhead wire, an insulating insulator, a load meter that detects the contact force of the sliding plate against the overhead wire, and a cylinder device in this order from above. Further, a conductive insulator is provided in parallel with the cylinder device and the insulating insulator, and the sliding plate and the conductive insulator are connected by a conductive cable. The contact force of the sliding plate to the overhead line is obtained by the load cell, and the cylinder device is expanded and contracted by this to make the contact force of the sliding plate to the overhead line constant. Further, when the current is not collected, the mount supporting the cylinder device and the conductive insulator is rotated so that the axial direction of the cylinder device is parallel to the longitudinal direction of the overhead wire, thereby lowering the sliding plate. There is.

[0003]

In the above current collector, the axial direction of the cylinder device is horizontal when the current is not collected, and the axial direction of the cylinder device is rotated from the horizontal direction to the vertical direction when the current is collected. There is. Therefore, the conductive cable between the lower end of the conductive insulator and the vehicle body is largely bent and twisted by the rotation. Since this conductive cable has a high voltage and is covered with an insulating material, it is difficult to bend it largely as described above, and bending causes a problem in life.

Further, the current collector of the vehicle is required to contact the overhead line in all traveling sections. To explain one example, (1) the height of the overhead line in the garage is 4700 mm (at this time, the current collector must be able to contact the overhead line), and (2) the normal traveling range (hereinafter referred to as the main line).
The height of the overhead wire in 4 is 5800 mm to 5300 mm, and (3) the height of the current collector when the current is not collected (that is, when the current collector is lowered) is 45000 mm (vehicle limit).
Must be: Therefore, the current collector is 800
Elevation of mm is required.

For this reason, the cylinder device of the current collector must be capable of generating a large amount of elevation. Further, the cylinder device needs to raise and lower the sliding plate at a high cycle in response to changes in the lift force acting on the sliding plate and the airfoil cover supporting the sliding plate and changes in the overhead wire height.

Further, the sliding plate and its airfoil cover receive a large force along the traveling direction of the vehicle. For this reason, the cylinder device must be able to withstand this force.

In addition, when a vehicle enters a tunnel,
Immediately after exiting the tunnel, it was revealed that large fluctuations in lift occurred on the current collector.

A first object of the present invention is to make it possible to obtain a large lifting amount with a small device.

A second object of the present invention is to facilitate moving up and down of the sliding plate and the conductive insulator.

A third object of the present invention is to reduce the height of the dome for accommodating the sliding plate, the conductive insulator, etc. when the sliding plate, the conductive insulator, and the like are rotated and projected upward. There is.

[0011]

The first object of the present invention is to:
A sliding plate, a first elevating device that elevates and lowers the sliding plate via an insulating insulator, a conductive insulator provided in parallel with at least one of the first elevating device and the insulating insulator, and the conductive member. A conductive means connecting the insulator and the sliding plate; and the first
Of the lifting device and the conductive insulator, or a second lifting device that lifts or lowers each independently, and a rotating device that rotates a pedestal on which the second lifting device and the conductive insulator are mounted. This can be achieved by configuring a current collector.

A second object of the present invention is to provide a sliding plate, an elevating device that elevates and lowers the sliding plate via an insulating insulator, and a conductive member provided in parallel with at least one of the elevating device and the insulating insulator. An insulator, a conductive means connecting the conductive insulator and the sliding plate, a drive device for raising and lowering or rotating the lifting device and the conductive insulator together or independently, and a lower end of the conductive insulator. This can be achieved by constructing a current collector including a connected conductive cable and a supporting unit that movably supports the conductive cable in the middle.

A third object of the present invention is to provide a sliding plate, an elevating device for elevating and lowering the sliding plate via an insulating insulator, and a conductive member provided in parallel with at least one of the elevating device and the insulating insulator. An insulator, a conductive means connecting the conductive insulator and the sliding plate, a platform for mounting the elevating device and the conductive insulator are rotated, and a central axis of the conductive insulator is horizontal. A rotating device that rotates the conductive insulator in a direction in which the conductive insulator is positioned above the insulating insulator when rotated, and the conductive insulator has a taper shape having a small diameter on the conductive means side. This can be achieved by arranging the conductive insulator side of the conductive insulator behind the other end side in the direction in which the insulator is horizontally rotated.

[0014]

According to the means for achieving the first object of the present invention,
The second lifting device and the like project upward by the rotating device.
With this position as a reference, the sliding plate moves up and down by the second lifting device and the first lifting device. For this reason, Kamata, which can reduce the amount of vertical movement of the second lifting device and the first lifting device and can support the notch of the roof of the vehicle body for installing the current collector, can reduce the notch.

According to the means for achieving the second object of the present invention, since the conductive cable is supported midway, it is possible to easily drive it up and down.

According to the means for achieving the third object of the present invention, since the top surface of the tapered conductive insulator becomes horizontal when the conductive insulator is rotated in the horizontal direction and is housed in the storage dome, The height of the top surface of the insulator becomes low. For this reason, the height of the storage dome for storing the storage dome is reduced, and the unevenness of the upper surface is also eliminated, so that the resistance is reduced and the generation of noise can be reduced.

[0017]

EXAMPLE This example will be described below with reference to FIGS. 1 to 5, the current collector 100 is installed on the roof 32 near an end portion of the vehicle body in the longitudinal direction, that is, a carriage (not shown) that supports the vehicle body. The roof 32 is provided with a known storage dome 95 that covers the lower portion of the current collector 100 during current collection and stores the current collector during non-current collection. On the upper surface of the storage dome 95, there is a known switchgear that covers the hole through which the upper portion of the current collector 100 projects.

The current collector 100 includes a sliding plate 110 as a current collecting member that contacts the overhead wire 51 to collect current, and a wind-proof wing-shaped cover 120 that supports the sliding plate 110 and covers the lower part thereof.
A first elevating device 500 that elevates and lowers the cover 120, an insulating insulator 130 installed between the cover 120 and the elevating device 500, and an elevating device 500 that elevates and lowers, and is provided in parallel with the elevating device 500. Fourth lifting device 30
0, a conductive insulator 140 provided in parallel with the lifting devices 500, 300 and the insulating insulator 130, and the lifting devices 500, 3
00 and the conductive insulator 140, a conductive cable 150 for conductive connection between the conductive portion at the upper end of the conductive insulator 140 and the conductive portion at the lower portion of the cover 120,
It includes a rotating device 710 for rotating the gantry 700 by 90 degrees, and a gantry 790 on which the gantry 700 and the rotator 710 are mounted and which is installed on the roof 32.

The electricity obtained from the sliding plate 110 is applied to the cover 12
0, the conducting cable 150 serving as a conducting means, the conducting insulator 140, and the conducting cable 155 are guided to the connector 158 installed on the roof 32. The connector 158 is connected to a known conductive cable (not shown). The conductive cable 150 does not have to have an insulating coating on its outer periphery. The conductive insulator 140 is formed by covering the outer periphery of a conductive member with an insulator, and is also called a cable head. The lower end of the conductive portion of the conductive insulator 140 is an L-shaped connector 145 having an insulating coating, and the conductive cable 15 is provided with an insulating coating.
Connected to 5. The conductive cable 155 can bend. A large distance is provided between the connectors 145 and 158 in order to reduce the bending of the conductive cable 155 and to facilitate the bending. The lower part is insulated by the insulating insulator 130 and the conductive insulator 140.

Rotating device 710 and lifting devices 300 and 500
Insulation insulator 130, cover 120,
And the sliding plate 110 moves up and down. The conductive insulator 140 is moved up and down by the fourth lifting device 600. The difference between the vertical movements of the cover 120 and the conductive insulator 140 is due to the conductive cable 150.
Bends and absorbs. The lifting device 300 includes two hydraulic cylinder devices 360 and 360. The lifting device 500 comprises a hydraulic cylinder device. Two cylinder device 36
The upper end of the cylinder of the cylinder device 500 is fixed by connecting the rods at the upper end of 0, 360 or 180th. Therefore, the cylinder device 500 is moved up and down by the cylinder device 360, and when the rods of the cylinder devices 500 and 360 are retracted, the height dimension thereof can be reduced.

Generally, the height of the overhead line from the track 50 to the overhead line 51 of the track (main line) that runs on business is 5000 mmm as a standard height, and the allowable range is −
It is 200 mm and +300 mm. Therefore, the overhead line height is 4800 mm to 5300 mm. The overhead line height in the garage is 4700 mm. From the garage to the main line is gradually changing. The height from the upper surface of the sliding plate 110 to the track 50 when the current is not collected, that is, when the current collector 100 is lowered is 4500 mm (vehicle limit height). For this reason,
The required lifting amount of the current collector 100 is 800 mm.

The required lifting amount of 800 mm is ensured, and the sliding plate 110 is applied to the overhead line 51 by a predetermined force against a lift force variation on the sliding plate 110 during high speed traveling and an external force acting on the sliding plate 110 from the overhead line 51. Since it is difficult for one lifting device to press and further move the lifting motion at a predetermined speed (frequency), three lifting devices 300, 500, 710 are provided. The elevating device 300 elevates and lowers the elevating device 500 to a predetermined height mainly when traveling on the main line.
The lifting device 500 is for pressing the sliding plate 110 against the overhead wire 51 with a predetermined force. The lifting amount of the lifting device 500 is 100 mm, and the lifting amount of the lifting device 300 is slightly over 500 mm. The remaining 200 mm or less is obtained by rotating the rotating device 710.

Cylinder devices 360 and 500 when power is not collected
The cylinder device 360 greatly raises the rod when traveling on the main line and collects the rod when traveling from the garage to the main line during current collection when the rod is fully lowered and is rotated by the rotating device 710 and stored in the storage dome 95. It is projected slightly higher. The elevating device 500 performs an elevating operation during traveling on the main line to bring the sliding plate 110 into contact with the overhead wire 51 with a predetermined force.

In FIG. 4, the sliding plate 110 is attached to the cover 120 via a spring (not shown) as is known. The cover 120 has a wing shape, and has a relatively large thickness in the vertical direction. The front edge in the traveling direction has a triangular shape protruding in the traveling direction. The train runs in both directions, so
In the case of traveling to the right in, the vehicle is stored in the storage dome 95. The triangular shape and thickness of the cover 120 are determined in consideration of noise reduction and the like. If the shape of the cover 120 is targeted in the traveling direction, the current collector can be used bidirectionally.

The insulating insulator 130 and the lifting device 500 are located at the center of the cover 120 in the width direction (vehicle width direction). The sliding plate 110 and the cover 120 are arranged around this center. The conductive insulator 140 is installed at a position eccentric to the insulating insulator 130 in the width direction and the traveling direction.

Rotating device 710 according to FIGS. 1, 3 and 5.
Will be described. A pedestal 700 on which the lifting devices 500 and 300 are placed is rotatably supported by a pedestal 790 by a pin 718. The pin 718 is rotated 90 degrees by a hydraulic cylinder device 711 via a link 715. The fixed end of the cylinder device 711 is a direction in which the elevating devices 500 and 300 are rotated in the horizontal direction during non-current collection,
It is located below the lifting devices 500, 300. Link 718
Since the cylinder device is provided, the length of the cylinder device 711 can be shortened and the cost can be reduced as compared with the conventional cylinder device. Further, the length of the gantry 790 can be shortened and the cost can be reduced as compared with the conventional case.

The arrangement of the conductive insulator 140 will be described with reference to FIGS. The conductive insulator 140 has a tapered shape in which the upper end is smaller in diameter than the lower end. The vertical central axis of the conductive insulator 140 has the upper end side inclined rearward with respect to the traveling direction. The inclination angle is the same as the inclination angle of the outer shape of the conductive insulator 140. Therefore, the position on the rear side of the conductive insulator 140 is vertical. Note that the conductive insulator 140 and the insulating insulator 130 have a large number of folds as is well known, but the folds are not shown here. The reference point of the inclination of the conductive insulator 140 is the upper end side. Because the upper end side of the conductive insulator 140 is a conductive portion, it is necessary to increase the insulation distance. However, since the lower end side is already insulated, the insulation distance may be small. Therefore, the tapered conductive insulator 1
The rear of the lower end of 40 is located on the front side in the traveling direction.

As described above, since the conductive insulator 140 is inclined and the rear side is vertical, when the current collector 100 is rotated as shown in FIG. 1, the upper end of the conductive insulator 140 becomes horizontal. . Moreover, since the position on the upper end side during current collection is not changed and the position on the lower end side is retracted, the height position of the upper surface of the conductive insulator in non-current collection in FIG. 1 is low. Therefore, the position of the upper end of the storage dome 95 becomes low, and the upper surface can be made horizontal. There is no unevenness on the top surface. Therefore, the running resistance is reduced and the noise is reduced. In the state shown in FIG. 1, that is, when the current is not collected, the conductive insulator 14
It is possible to obtain a sufficient gap between the upper surface side of 0 and the upper surface of the storage dome 95.

The arrangement of the conductive cable 155 will be described with reference to FIGS. 1, 2, 6 and 7. The conducting cable 155 is taken out horizontally from the conducting insulator 140 in the width direction of the vehicle body, and is bent in the longitudinal direction of the vehicle body so that the roof 3
2 connector 158. Conductive cable 1
The portion 55 is largely bent downward in a portion along the longitudinal direction of the vehicle body. Further, the conductive cable 155 is inclined from the upper part toward the connector 158 on the roof 32 in a portion along the longitudinal direction of the vehicle body. Reference numeral 159 denotes a cylinder that supports the conductive cable 155, and is installed at the upper end of the pillar 159b provided on the roof 32. Conductive cable 15
5 can freely pass through the cylinder 159. Both ends of the cylinder 159 are enlarged. The cylinder 159 is a portion of the conductive cable 155 along the longitudinal direction, and the conductive insulator 140 is more than the flexible portion.
It is installed on the side. The height position of the cylinder 159 is the rotation device 7
It is an intermediate part of the range in which the connector 145 of the conductive insulator 140 is moved up and down by 10 and the cylinder device 650.

According to this structure, the conductive cable 15
Since the middle part of 5 is supported by the cylinder 158, and the conductive insulator 140 side is supported by the cylinder 159 rather than the largely bent portion, the resistance of the operation of the rotating device 710 and the lifting devices 300, 500 can be reduced. is there. Further, since the height position of the cylinder 159 is in the middle of the ascending / descending range of the connector 145, the bending of the conductive cable 155 in the vertical direction can be reduced, and the life can be extended. Also, the connector 1
Since the conductive cable 155 is arranged from 45 in the width direction of the vehicle body, even if the conductive cable 155 is rotated by the rotating device 710, the bending of the conductive cable 155 can be reduced and the life can be extended.

The operation and effect of the cylinder 159 is due to the rotation device 710.
Similar effects can be obtained even in the case of not having.

Further, in FIG. 6, as indicated by an imaginary line, the conductive cable 155 is arranged in the horizontal direction, especially in the lifting device 5.
It may be bent to the rear side of 00, 300. In this case, a receiving seat 159c for the conducting cable 155 is provided. According to this, it is possible to bend it more greatly in a short distance. In addition, the rotating device 710 and the lifting device 500,
It is thought that the power of 300 can be reduced.

In FIG. 3, FIG. 4, and FIG. 8 to FIG.
The cylinder device 360 of the lifting device 300 is a normal cylinder device. The lower end of the cylinder device 360 is a mount 700.
Fixed on top. The mount 180 is fixed to the upper end of the piston rod 362 of the cylinder device 360 with a screw. The gantry 180 has an elliptical plan shape (long running direction of the vehicle). The two cylinder devices 360, 360 are located before and after the first elevating device 500 in the traveling direction of the vehicle. The current collector 100 receives an external force from the traveling direction of the vehicle. Two cylinder devices 36 along this direction
Since 0 and 360 are arranged, the strength in this direction can be increased, the configuration can be simplified, and the cost can be reduced.

The first elevating device 500 is installed in the middle of the two cylinder devices 360, 360. Lifting device 50
0 is fixed to the frame 180 and hung. Lifting device 5
The lower end of 00 is not fixed to the mount 700.

A cover 285 covers the lower part and the lower part of the insulator. The cover 285 covers the lower part of the insulating insulator 130, the pedestal 180, and the side surfaces of the elevating device 500 and the cylinder devices 360, 360. The height of the cover 285 is a range protruding from the storage dome 95. The planar shape of the cover 285 is an ellipse. The cover 285 is divided in half in the vertical direction. From frame 180 to cover 28
The seat supporting 5 is projected, but it is not shown.

On the mounting seat 223 which is moved up and down by the elevating device 500, an insulating insulator 13 is mounted via a load meter 226.
0 is attached. Mounting seat 223 and lifting device 50
A length measuring instrument 250 is arranged between the side surface of 0. A length measuring instrument 350 is arranged between the side surface of the cylinder device 360 and the mounting seat 40. The length measuring devices 250 and 350 detect the amounts of lifting and lowering of the lifting devices 300 and 500, respectively. The length measuring devices 250 and 350 are, for example, publicly known magnet scales, which are composed of a cylinder in which a plurality of magnets are arranged in the longitudinal direction and an iron bar inserted in the cylinder. The iron bar of the length measuring instrument 250 penetrates the gantry 180. The length measuring devices 250 and 350 are installed at positions on both sides of a line connecting the cylinder device 360 and the elevating device 500, which connects them. As a result, the overall outer shape can be reduced. 255 and 355 are ball joints that connect the cylinder and the rod, and allow eccentricity between them.

Details of the lifting device 500 will be described with reference to FIG. The lifting device 500 is a hydraulic cylinder device 510.
And a guide device 520. The cylinder head 5 on the piston 513 side of the cylinder 511 of the cylinder device 510
Three oil inlets and outlets 516 are provided on the side surface of 14. The cylinder 511 is made up of a triple tube and has an inner tube 51.
Reference numeral 1a is a normal cylinder in which a piston 522 and a rod 512 are arranged. One oil inlet / outlet 516 of the cylinder head 514 communicates with the inside of the cylinder 511a. A passage between the inner cylinder 511a and the intermediate cylinder 511b connects the chamber on the rod 512 side and one entrance / exit 516. Between the middle cylinder 511b and the outer cylinder 511c is a discharge passage for oil leaking from between the cylinder head 515 on the rod 512 side and the rod 512. This discharge passage is connected to another oil inlet / outlet 516. The cylinder head 514 is screwed inside the outer cylinder 511c and is fixed by a fixing nut 517. The cylinder head 515 is screwed inside the outer cylinder 511c and is fixed by a fixing nut 518. Tube 511a and tube 511b
Are sandwiched between the steps of the two cylinder heads 514 and 315. An oil seal is arranged at a contact portion between the cylinder heads 514, 515 and the cylinders 511a, 511b, 511c and the rod 512. The rod 512 penetrates the pedestal 180 and is attached to the upper mounting seat 223 by screws 51.
It is fixed by 2b. A load meter 226 is attached above the attachment seat 223.

The guide device 520 is a device for linearly guiding the cylinder 522 of the cylinder device 510. The cylinder 522 guided by the linear guide device 530 is fixed to the mounting seat 223 with a screw and fixed with a fixing nut 523. The lower end of the cylinder 522 is open. The cylinder 535 accommodating the linear guide device 530 is fixed to the frame 180 by welding.
The linear guide device 530 is fixed to the cylinder 535 by a stop ring 532. The cylinder 535 is the cylinder head 5.
It is fixed to 14 with a bolt nut (not shown).

According to this, when the rod 512 is projected, the mounting seat 223 rises. Since the rod 512 is supported by the guide device 520 via the cylinder 522 having a large diameter, even if there is only one cylinder device, the rod 512 can resist the external force in the traveling direction.

Since the lifting device 500 is suspended on the pedestal 180 that is lifted by the cylinder devices 360, 360, when the current collector 100 is lowered, the cylinder devices 360, 360 and the lifting device 500 are in parallel. Therefore, the height of the current collector 100 at this time can be reduced.

Next, the support structure of the conductive insulator 140 will be described with reference to FIGS. 4, 12, and 13. The conductive insulator 140 may be installed on the pedestal 180. According to this, the installation position of the conductive insulator 140 greatly overhangs with respect to the center of the gantry 180, which is not preferable from the viewpoint of the strength of the cylinder device 360. Also, the pedestal 18
When the conductive insulator 140 is installed at 0, the cover 120 is moved up and down by the second elevating device 500, but the conductive insulator 140 is not moved up and down. Therefore, the conductive cable 1
50 is bent as the cover 120 moves up and down, which is problematic in terms of life.

The configurations of FIGS. 12 and 13 are intended to solve this problem, and a fourth elevating device 600 for elevating the conductive insulator 140 is additionally provided. The fourth lifting device 600 includes a lifting device 500 and a cylinder device 3.
It is installed on the side of 60 and 360. Fourth lifting device 6
00 is the height of the sliding plate 110, that is, the cylinder device 36.
It operates with the operation of 0,520. According to this, the amount of bending of the conductive cable 150 and the frequency of bending can be reduced, and the life thereof can be improved.

The lifting device 600 is a hydraulic cylinder device 6.
10 and a link mechanism 620 rotated by this
And a guide device 630 for vertically guiding the support base 640 of the insulating insulator 140. The link mechanism 620 includes a first link 621 attached to the attachment seat 40 in the vertical direction, and a second link 622 attached to the tip of the first link 621 in the horizontal direction. Link 6
The tip of 22 is rotatably attached to the support base 640. The links 621 and 622 are rotatable with respect to the attachment. The cylinder device 610 is arranged between the second link 622 and the mounting seat 40a. Link mechanism 62
There are two 0 links 621 and 622 when viewed from above. The links 622 and 622 are connected to both sides of the support base 640. The piston rod of the cylinder device 610 is connected to a shaft 623 that connects the two links 622. 6
Reference numeral 25 is a shaft that connects the links 621 and 622 on both sides. The mounting seat 40a is placed on the mounting seat 40.

The guide device 630 comprises a mounting seat 631 standing upright on the mounting seat 40a, a guide seat 632, and a guide seat 633 provided on the support base 640 and meshing with the guide seat 631. The support seats 640 are vertically guided by the guide seats 632 and 633. Information seat 63
1, 632 are known linear guide devices, for example. The guide device 630 is installed in the space surrounded by the cylinder device 610, the support base 640, and the two links 622.
According to this, as the cylinder device 610 expands and contracts, the support base 640 moves up and down vertically.

The insulating insulator 140 has a total lifting amount of the cylinder device 360 and the lifting device 500, that is, the sliding plate 11.
It is necessary to go up and down corresponding to the 0 position. Therefore, a length measuring device 650 for detecting the amount of protrusion of the piston rod of the cylinder device 610 is installed. The length measuring instrument 650 is
In the space between the link 621 and the cylinder device 610, the link 622 and the mounting seat 39 are rotatably connected. The length measuring device 650 is similar to the length measuring devices 250 and 350. The upper end of the length measuring device 650 has two links 62.
It is rotatably connected to a shaft 626 that connects the two.

The control device 440 uses the length measuring instruments 250 and 350.
The height of the sliding plate 110 is obtained from the respective detected values, and the cylinder device 610 is driven so that the height of the insulating insulator 140 corresponds to the height. Cylinder device 610
Operates in synchronization with the cylinder devices 360, 360 and the lifting device 500. In this case, when the height of the sliding plate 110 is higher than a predetermined value (a value slightly lower than the height (4700 mm) of the overhead wire 51), the upper end of the conductive insulator 140 is lower than the sliding plate 110. The height command value is output to the cylinder device 610 so that the cylinder device 610 is positioned at. This is to prevent the upper end of the insulator 140 from coming into contact with the overhead wire 51. The conductive insulator 140 is mounted on the sliding plate 110.
The lower value is, for example, 80 mm. Sliding plate 11
When the height of 0 is less than the predetermined value, there is no risk of contact with the overhead wire 51, and therefore the upper end of the conductive insulator 140 may be at the same height as the sliding plate 110. At this time, the conductive insulator 14
If the lower end of 0 is burlapped to tasks 700 and 790, the overall height can be reduced.

According to this, since the conductive insulator 140 can be moved up and down by following the sliding plate 110, the bending of the conductive cable 150 can be reduced and the life can be improved. When the support base 540 is lowered to the lowermost end, the minimum height of the support base 540 can be lowered, and the lifting device 600 can be made smaller.
In the above embodiment, the link mechanism 620 can be a parallelogram link. According to this, the guide device 6
30 can be eliminated or its construction can be simplified.

This is a traffic control device that commands the control device 440 to send information about a non-tunnel section (called a light section) and information about a traveling speed (which means information about low speed or high speed). Operation control device 4
30 is mounted on the vehicle. The control device 440 inputs the analog signals of the detectors 226, 250, 350, 412, 414, estimates and calculates the contact force to the overhead line 51 from the detection value of the load meter 226, and the length measuring devices 250, 350,

The force control valve and the solenoid proportional valves 421, 431 are provided with respective force and position control amounts. Therefore, when the cylinder device 510 is force-controlled, the two electromagnetic check valves 413 and 413 are opened and the four-way servo valve 41 is opened.
Switch 1 to either one. However, when the force control is not performed, that is, when the sliding plate 110 is arranged within the vehicle limit, the position control is switched to the positioning operation. When performing positioning control of the cylinder devices 360, 360,
The solenoid check valve 413 is opened and the solenoid proportional valve 421 is switched to either one. Controller 44

[Table 1]

Table 1 shows the control contents according to the running conditions of the control device 440. (1) In the light section (non-tunnel section), only the cylinder device 360 is position-controlled in the section from the garage to the main line, and the cylinder device 510 positions the rod 512 at the lowest end. The control device 440 outputs the height based on the height of the overhead wire 51 obtained by measurement in advance to the cylinder device 510 as the positioning pattern 441, and the rod 51
The protrusion margin of 2 is changed. Since the traveling speed is low, the lift force fluctuation does not act on the sliding plate 110 and the cover 120, so that the current can be sufficiently collected even if the height of the sliding plate 110 is fixed.

(2) In the main line section of the light section, the cylinder device 360 is positionally controlled and the cylinder device 510 is force-controlled to press the sliding plate 110 against the overhead wire 51 with a predetermined force. That is, on the main line, the overhead line 51
The height varies greatly in the range of 4800 mm to 5300 mm, and it is necessary to move up and down accordingly. The stroke of each of the cylinder devices 510 and 360 is 100.
mm, a little over 500 mm. Therefore, the control device 440
Is a target height based on the height of the overhead wire 51 obtained by measurement in advance as the positioning pattern 441.
It outputs to 60, and the height of the sliding plate 110 is located near the height of the overhead line 51 at the running position. However, lift force fluctuations act on the sliding plate 110 and the cover 120, and the height of the overhead wire also changes as the vehicle travels. Therefore, the contact force is obtained by the load meter 226, and the cylinder device 510 is controlled so that the contact force becomes a predetermined value. As a result, the sliding plate 110 can be pressed against the overhead wire 51 with a constant force, disconnection can be prevented, and disconnection of the overhead wire 51 can be prevented. The cylinder device 360 is operated with the expected height of the overhead wire 51 as a reference, and the stroke of the cylinder device 510 is small.
0 can be moved up and down to the position of the overhead line 51. The frequency of raising and lowering the cylinder device 360 depends on the cylinder device 5.
Much lower than the frequency of 10 lifts. Cylinder device 3
The protrusion allowance of the rod 362 of 60 allows the cylinder device 510 to move up and down, and is determined in consideration of this. For example, "
-50 mm ".

(3) When power is not collected in the garage or the like in the light section, the rods 512, 362 and 362 are controlled by positioning control of the cylinder device 360 and the cylinder device 510.
Is lowered to the lower end, and then the valve 413 and the like are closed.

(4) When traveling at high speed in the tunnel section, the height of the sliding plate 110 is kept high for a predetermined time immediately after the current collector 100 rushes into or out of the tunnel. Cylinder devices 510, 3 so that the height becomes the reference height (5000 mm) of the overhead line 51.
Control 60 to stop lifting at that position. This is called fixed mode. That is, after lowering the rod 312 of the cylinder device 360 to the lowermost end, the cylinder device 36
All the electromagnetic check valves 413 of 0 are closed, and the force control is stopped. At the same time, the cylinder device 360 moves the sliding plate 110.
Is moved up and down so that the reference height (5000 mm) is reached, and then all the electromagnetic check valves 41 of the cylinder device 360 are
3 is closed and the position control is stopped. During this predetermined time, extremely large lift fluctuations occur, and therefore, if position control and force control are carried out, the overhead line 51 may be cut off. In addition, there is a possibility that a large disconnection may occur due to lift force fluctuations. However, as described above, the cylinder device 510,
If the raising / lowering operation of 360 is stopped, the cylinder device 51
Since 0 and 360 are hydraulic type, this can be prevented. Further, since the sliding plate 110 is located at the reference height, it can substantially follow even if the height of the overhead line 51 changes. In addition, this section is a short time, and the other current collectors 100 are not in the fixed mode, so that the current collection is sufficiently performed. The position of the tunnel can be recognized by detecting the position signal from the ground side.

The period of the fixed mode C for a predetermined time immediately after entering the tunnel or immediately after exiting the tunnel may include the predetermined time immediately before that. Further, in the above embodiment, the sliding plate 110 is fixed to the reference height of the overhead wire 51 for a predetermined time, but it is also possible to stop the lifting operation in a state immediately before the predetermined time. Further, although the fixed mode C is set by time, it may be set to a predetermined section immediately after entering the tunnel or a predetermined section immediately after leaving the tunnel. The section can be recognized by detecting the position signal from the ground side. Also, it can be recognized by measuring the traveling distance.

(5) In the other sections that run at high speed in the tunnel section, positioning control and force control are performed as in (2) above.

(6) Failure of the control device 440, or any of the detectors 226, 250, 350, 414, 650
If the cylinder fails, the cylinder devices 510 and 360 are placed in the fixed mode. This is to prevent disconnection of the overhead wire 51 due to excessive protrusion of the rods 212 and 312.

(7) During gusts, the cylinder devices 510, 3
60 into fixed mode C. This is to prevent the overhead wire 51 from being cut by an excessive lift. Gusts are detected by a notification from the ground station.

In the fixed mode C of (6) and (7), the traveling speed is low like the traveling speed between the garage and the main line. The driver manually slides the sliding plate 110.
Can be moved to the reference height. In addition,
In the fixed modes of (6) and (7), since the vehicle travels at a low speed, it is not necessary to fix the cylinder devices 510 and 360, and the length measuring device 250 and 350 are used to slide to the height of the overhead line 51 stored in advance. The heights of the plates 110 may be matched. Particularly, the positioning control mode A described in (1) above is set between the garage and the main line.

Fixed mode C in the tunnel section of Table 1
This will be described with reference to FIG. In FIG.
The waveform of (A) is a position pulse when the leading car passes through the tunnel. The waveform of (B) is a position pulse when a vehicle equipped with the current collector 110 passes through a tunnel. The waveform (C) is an example of a lift waveform that acts on the cover 120 of the current collector 100 when the vehicle body equipped with the current collector 100 passes through the tunnel. The waveform of (D) is the cylinder device 510.
It shows the timing to switch to fixed mode. The waveform (E) shows the timing when the cylinder device 510 is set to the fixed mode. In (D) and (E), the high level indicates the period in which the cylinder devices 510 and 360 are set to the fixed mode C. It should be noted that the number of vehicles equipped with the current collector 100 (hereinafter referred to as a vehicle) will be described as one.

_One hour after the leading car rushes into the tunnel, _one hour after Tx, the loaded car rushes into the tunnel. Then, during Tx ₂ thereafter, a large lift variation occurs on the cover 120 of the mounted vehicle. When the leading car exits the tunnel, a large lift variation occurs in the cover 120 of the mounted car after Ty ₁ . This continues for the duration of Ty ₂ . Tx ₁ , Tx ₂ , Ty ₁ , Ty ₂
Varies depending on the distance from the leading car to the mounted car, speed, etc. It is possible to operate the cylinder device 510 during the periods Tx ₂ and Ty _{2 in} which a large lift fluctuation occurs, but since the large force acts in a high cycle, the cylinder device 510,
It is necessary to make 360 large and to raise and lower the speed. Therefore, during this period, the cylinder devices 510 and 360 are fixed so as not to move up and down. Some disconnection (overhead wire 51
The sliding plate 110 is separated from the sliding plate 110. However, if a plurality of current collectors 100 are provided, current can be collected. From immediately before the periods Tx ₂ and Ty ₂ , the cylinder device 510,
Fix 360 to prevent fixation delay. The lengths of the periods Tx ₁ and Ty ₁ immediately before this can be set as appropriate, and the fixed mode may be started before the mounted vehicle rushes into or projects into the tunnel. The position information of the tunnel is received from the operation control device 430. Since the cylinder devices 510 and 360 are non-compressible oil type, their positions can be kept constant even if there is a large lift variation due to a large wind.

Position control and force control are performed in the section (5) from the time when the portion of the current collector 100 rushes into the tunnel to the time when it exits.

The control flow chart of the control device 440 will be described with reference to FIG. After initial setting of the control device 440 and the hydraulic circuit, a point (light section, tunnel section)
After receiving information such as information and traveling speed (low speed, high speed) from the operation control device 430, the three modes (A mode,
Set the B mode and C mode (step S1)
0), steps A10 to A40, B10 to B of each mode
Proceed along 30, C10. The A mode and the B mode may be executed simultaneously.

In case of positioning control mode A Step A10: A positioning target value h * of the cylinder device 360 is set from a height target value predetermined from the track 50 to the overhead line 51 by position information.

Step A20: The current height hx of the gantry 180 is sequentially detected by the value of the length measuring machine 350.

Step A30: After the position deviation amount of (h * -hx) is calculated, the positioning control of the cylinder device 360 by PID (proportional, integral, differential) compensation is performed to bring the sliding plate 110 into contact with the overhead line 51. Then, the signal of the load cell 226 is obtained. In this case, the contact force of the sliding plate 110 to the overhead line 51 is about 100N.

Step A40: (h * -hx) is almost 0
If it is equal to, the process returns to step S10.

In the case of force control mode B: Step B10: The pushing force target value f * to the overhead line 51 which is predetermined by the position information is set as the pushing force target value f * of the cylinder device 510.

Step B20: The load cell 226 sequentially detects the pushing force fx.

Step B30: Detected pushing force fx
, The overhead line 51, the sliding plate 110 (mass m1, acceleration y1 ″), the cover 120 (mass m3, acceleration y1)
3 ″) acting on the contact force f (= fx−m1 · y)
1 ″ -m3 · y3 ″ -fq) is calculated to estimate the state. However, although the lift force fq is not directly detected, it is virtually obtained. Then, using the deviation amount of the pushing force of (f * -f),
The pushing force of the cylinder device 510 is controlled by the feed back control, and the cover 120 is made to follow the contact wire 11 in contact therewith. As a result, even if the height of the overhead wire changes and the contact force fluctuates greatly, the fluctuation of the contact force is controlled to a small value so that the sliding plate 110 does not easily separate from the overhead wire 51.

Step B40: If (f * -f) becomes substantially equal to 0, the process returns to step S10.

In the case of the fixed mode C Step C10: The cylinder device 510 is instructed of the shortest length, and the cylinder device 360 is instructed of the length so that the sliding plate 110 is located at the reference height.

Step C20: Cylinder devices 510 and 3
The length measuring instrument 25 indicates that 60 has reached the respective command length.
When it is detected by 0,350, the electromagnetic check valve 413
Is closed to stop the expansion and contraction of the cylinder devices 510 and 360.

The control of the cylinder device 610 is substantially the same as the control of the cylinder device 360.

As described above, the positioning control corresponding to the change of the overhead wire height of 600 mm and the push-up force control for suppressing the disturbance caused by the external force of the overhead wire are performed so that the sliding plate 110 always contacts the overhead wire 51. As a result, the overall current collection performance is improved. Further, since the fixing operation is positively performed against the disturbance caused by the fluctuation lift due to the change of the traveling route such as the tunnel, the fluctuation of the contact force between the overhead wire 51 and the sliding plate 110 can be reduced.

In each of the above embodiments, each of the first lifting device and the second lifting device is a cylinder device.
A link mechanism (for example, a pantograph lifter) may be used. For example, when the first lifting device is of a pantograph type, a pantograph type lifter is provided on a frame suspended from the frame 180, and a load meter 226 or the like is mounted on this lifter.

In the above embodiment, the first lifting device 50
Although the command for raising and lowering 0 is given by the detection value of the load meter 226, it may be a detection value of a detection meter that measures the distance to the overhead wire 51 as is well known. Further, as is well known, the load cell can be provided closer to the sliding plate 110 side than the insulating insulator 140 by using an optical fiber.

Although the cylinder device 510 of the first elevating device 200 and the cylinder device 360 of the second elevating device 300 of the above embodiment are separate, they may be combined into one by a multistage cylinder device. When sliding the cylinder devices 510 and 360 with the pneumatic cylinder device, means for fixing the protruding length of the rod in the fixing mode C is provided. For example, a means for gripping the rod is provided outside the cylinder.
