Description

Description: TECHNICAL FIELD The present invention relates to an attachment device for attaching a snow-hardening ring to an overhead line such as an overhead transmission line to prevent snow from adhering to the overhead line.

[Conventional technology]

As shown in Japanese Patent Laid-Open No. 182408/1983, a mounting device for mounting a snow-difficulty ring on an overhead power transmission line, particularly an elevated power transmission line, can be mounted on the power transmission line via rollers. And a device moving means connected to the clamping means. The two means are used to intermittently travel the power transmission line,
It is designed to be fitted with a snow ring. The mounting device includes a ring holding piece in which a large number of snow-hardening rings are laminated on a rod, a cylindrical storage case in which a large number of ring-holding pieces are circumferentially mounted, and a snow-hardening ring of the holding piece for a power transmission line. And a ring clamp means for crimping the snow-hardening ring sent to the power transmission line to the power transmission line, and a control means for controlling these. The power source of each of the above means is pneumatic pressure, which is supplied to the mounting device from an air compressor on the ground via a hose.

By mounting this mounting device on a power transmission line and sending air under pressure, the mounting device mounts a snow-hardening ring while traveling along a running line.
While working from one of the towers to the other tower, the limit switch releases the clamped state of the means for clamping the power transmission line, so that the worker at the one tower pulls the hose to Collect the mounting device to one of the towers.

[Problems to be solved by the invention]

As described above, the work of mounting the snow-difficulty ring (including running) is started by the supply of air, and the work device is released from the clamp means for running when the working device hits an obstacle. According to this, it is considered that a power source is unnecessary, the configuration is simple, and the reliability is high.

However, according to the above, since only the mounting work (including running) and the running stop are performed, other work cannot be performed. Or, other work cannot be easily performed. In particular, of the two clamp means for clamping the power transmission line, the fixed clamp means is also used as the ring clamp means, so that it cannot be run except for the ring mounting work.

For example, if there is a worker in one of the steel towers, run the mounting device from the one steel tower to the other steel tower (the ring is not mounted), and if the worker arrives at the other steel tower, It is conceivable to move it backwards and perform the ring attachment work at this time.

If it is found that the ring has not been attached due to a bad caulking operation during the ring attaching operation, it is necessary to move the attaching device backward to the relevant portion and perform the caulking operation again. Alternatively, do not drive the car and let only caulking work.

Further, when a failure of the mounting device is found, it is necessary to interrupt the caulking work and move the mounting device forward or backward to collect the steel in one of the towers.

As described above, various work modes are conceivable, and it is desirable that the worker can specify the mode.

Further, since the moving means for moving the clamp means for clamping the overhead wire (that is, the driving means for causing the mounting device to travel) is the air cylinder device, the air cylinder device is proportional to the stroke amount and the weight of the mounting device. Will consume more. The air compressor becomes big and heavy,
In addition, the hose connecting the mounting device to the ground also has a large diameter.

An object of the present invention is to be able to perform various operations and to be light in weight as a whole.

[Means for solving problems]

The present invention is characterized in that it is provided with two clamp devices for clamping an overhead wire, a crimping device for attaching a ring to the overhead wire, and an electric motor provided as a manual movement of the clamp device.

[Action]

A clamp device for clamping the overhead wire is provided separately from the caulking device, and an electric motor is provided as a drive source for moving the clamp device.
Various operations such as running the mounting device can be performed. Also, the compressor will be smaller and lighter.

〔Example〕

The present invention will be described below with reference to an embodiment shown in FIGS. This embodiment is a device for attaching a snow-hardening ring to an overhead wire.

First, the snow-hardening ring used will be described with reference to FIG.
The snow-hardening ring 1 of FIG. 7 is a known one, and is shown before being attached to the overhead wire. The two semicircular pieces 1A and 1B are split in half and their ends are open, and the two pieces are pushed to the other piece so that the male portion 1a at the tip of the one piece 1A is connected to the other piece 1B. It is fitted and integrated with the female portion 1b of the female portion at the tip (this is called caulking).

Next, the structure of the working device will be described with reference to FIGS. FIG. 3 is a right side view of FIG. 1, but without the air compressor 6. FIG. 5 shows only the upper and lower holding members 41. The stopper 43 is shown in FIG. 6 for easy understanding.

2 is fixed to the frame 23. Sprockets 25 and 26 are attached to the front and rear of the frame 23. One sprocket 26 is rotated by the motor (with a speed reducer) 5 installed on the frame 23. A chain 27 is endlessly attached to the front and rear sprockets 25 and 26 via a clamp device 29. Therefore, the clamp device 29 moves forward or backward by the forward and reverse rotations of the electric motor 5. The moving range of the clamp device 29 is shown by a solid line and an imaginary line. The movement range can be changed by changing the position of the limit switch mounted on the frame 23. The clamp device 29 is guided by a guide (not shown) provided in the frame 23 so as not to incline in the radial direction and the front-back direction of the overhead wire 20. The clamp device 28 is fixed to the frame 23. The clamp devices 28 and 29 clamp an overhead line with an air cylinder device (not shown) like a known device. An air cylinder device is provided on each side of the overhead wire in one clamp device.

When the overhead wire 20 is clamped by the clamp device 29 (the clamp device 28 is not clamped), the motor 5 is energized to move the clamp device 29.
Runs. When the clamp device 29 has moved, it is clamped by the clamp device 28, then the clamped state of the clamp device 29 is released, and the motor 5 is energized to reverse the rotation and the clamp device 29 is moved in the opposite direction. Clamp device 2
If the wire 9 is moved from left to right in FIG. 1 while the overhead wire 20 is clamped, the attachment device moves to the left (runs),
If it is moved in the opposite direction, it will run in the opposite direction.

U-shaped frames 31, 31 are provided at two points before and after the frame 23.
And the base 33 is mounted immediately below the overhead wire 20 to store the compressor 6 and the storage case 40 for the snow-retaining ring 1.

The command device forwards, reverses, stops at the same time automatic driving is performed while the caulking work is performed, forwards only for traveling, reverses,
The same stop can be commanded to drive only one caulking operation. The control panel 34 drives each device based on the command.

A compressor 6, a storage case 40 for the ring 1, a caulking device 70 for the ring 1, and the like are installed on the base 33 below the frames 31, 31. The caulking device 70 is installed directly below the overhead line 20.

The storage case 40 has a substantially cylindrical shape, and is installed so that its axial direction is parallel to the overhead wire 20 so that it can rotate.

The storage case 40 includes a holding member 41 that holds the ring 1 in an opened state before crimping, and cylinders 45 and 46 fixed to both ends of the holding member 41. This forms one storage case 40. A large number of holding members 41 are installed at equal intervals along the inner surfaces of the cylinders 45 and 46.

In FIGS. 5 and 6, the holding member 41 is attached to the inner surfaces of the cylinders 45 and 46 via the seat 42. Holding member 41
Is substantially rectangular in cross section. The ring 1 is mounted on a support member 41 as shown. Therefore, the ring 1 can move relative to the holding member 41 only in the longitudinal direction of the holding member 41, but does not fall off. A large number of rings 1 are stacked in one storage member 41.

The outer surface of the cylinder 45 is supported by four rollers 48.
The inner surface of 6 is supported by four rollers 49, and the storage case 40 is rotatable.

Vertical seats 50, 51 close to the end faces of the cylinders 45, 46
Is installed on the base 33. The rollers 48 and 49 are attached to the vertical seats 50 and 51.

Since the end of the holding member 41 on the side of the vertical seat 50 is close to the vertical seat 50, the ring 1 does not drop off from the end. A stopper 43 is provided at the other end of the holding member 41 at the end of the holding member 41 to prevent the ring 1 from falling off. The stopper 43 slightly projects toward the center of rotation of the storage case 40.

A chain 55 is fixed to the outer surface of the cylinder 46 in an endless manner. A sprocket 57 of a rotary actuator 56 powered by air is engaged with the chain 55. The rotary actuator 56 is attached to the vertical seat 51.

Reference numeral 60 denotes a supply device for supplying the ring 36 of the holding member 41 to the caulking device 70, which mainly comprises an air-driven rodless cylinder device 61. The axial direction of the rodless cylinder device 61 is parallel to the axial direction of the storage case 40, that is, the holding member 41. Rodless cylinder device 61
Is installed in the storage case 40 and below the uppermost holding member 41. The shaft ends of the rodless cylinder device 61 are attached to the brackets 62 and 63, respectively.
It is fixed at 1. The shaft end on the side of the caulking device 70 is located inside the storage case 40, and the shaft end on the other end side projects outside the storage case 40.

As is well known, the rodless cylinder device 61 has an operating body 65 that slides on the outer surface of the cylinder. In order to prevent the rotation of the operating body 65, a guide bar 64 is provided outside the cylinder.
Are provided in parallel.

A push-out piece 67 for pushing the ring 1 is provided on the upper surface of the operating body 65. The actuation body 65 is an end portion of the holding member 41 (vertical seat 5
Since it cannot move to the vicinity of 0), a bracket 66 protruding from the actuating body 65 to the vertical seat 50 side is provided, and an extruding piece 67 standing upright is provided at the tip of this. As a result, the last ring 1 of the holding member 41 also crimps the device 7.
0 can be supplied.

As shown in FIG. 6, the engaging piece 67 is concave and contacts both ends (each piece 1A, 1B) of the ring 1 in the horizontal direction. Engagement piece 6
7 is provided so as not to hit the stopper 43 at the end of the holding member 41.

In FIG. 5, in order to feed the ring 1 from the uppermost holding member 41 to the caulking device 70, there is an opening 50a for passing the ring 1 at the end of the vertical seat 50 between them.

Further, an opening 50b is provided at another position of the vertical seat 50 so as to face the holding member 41. This opening 50b is for supplying the holding member 41 with the ring 1 in advance.
When the required number of rings 1 is supplied to one holding member 41,
The storage case 40 is rotated by one pitch by using the rotary actuator 55, and the ring 1 is supplied to the adjacent holding member 41 as described above. When the supply of the ring 1 is completed, the lid 53
Close with.

The rodless cylinder device 61 presses the pushing piece 67 toward the caulking device 70 side using air as a power source.
When the caulking device 70 rises to attach the ring 1 to the overhead wire and the caulking device 70 descends, the pushing piece 67 supplies the ring 1 to the caulking device 70. When the last one ring 1 of the one holding member 41 is supplied to the caulking device 70, the limit switch (not shown) detects the position of the pushing piece 67, that is, the operating body 65 in this position, and the operating body 6
5 is retracted into bracket 63. When the actuating body 65 retracts, the pushing piece 67 and the other end of the holding member 41 and the roller 4
Since it is located in the space 69 between the storage case 40 and the housing 9, the storage case 40 is rotated by one pitch using the rotary actuator 56. Since the push-out piece 67 faces the adjacent holding member 41, the operating body 65 is driven toward the caulking device 70 side.

The caulking device 70 is for caulking the ring 1 and attaching it to the overhead line 20, and its configuration is known. That is,
When the ring 1 is supplied between the pair of left and right caulking members,
The air driven cylinder device 90 raises it to the position of the catenary, and then the respective caulking members are moved to the center side by the air driven cylinder device to join the pieces of the ring 1 into a ring shape. Next, the cylinder device 90 lowers the original position.

The caulking device 70 is installed near the vertical seat 50.
The cylinder device 90 is fixed to the vertical seat 90 with a band 91.

In order to prevent the ring 1 of the holding member 41 from being released from the opening 50a when the crimping device 70 is lifted, a closing plate 89 that closes the opening 50a by lifting the crimping device 70 is suspended from the crimping device 70. .

The work of attaching the ring 1 by the caulking device 70 is performed when the movement of the working device 10 is stopped. If the mounting work is performed every time the movement is stopped, the mounting pitch of the ring becomes the unit of movement range of the clamp device 29.

Although a limit switch for detecting the operating state of each device is installed in each device, it is not shown. A solenoid valve for controlling the air supply is installed in the control panel.

As described above, since the clamp device that clamps the overhead wire is driven by the electric motor, it is possible to freely move forward, backward, and stop. Also, since the caulking device only caulks, the caulking work can be freely performed and stopped. Is something that can be done.
Also, since an electric motor is used, the air compressor can be made lightweight and compact. The cable can also be made smaller.
