Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to refueling vehicles, and in particular allows multiple hose hangers for hooking refueling hoses to be driven up and down using a single hydraulic cylinder device. Regarding refueling vehicles.

[Prior art and problems]

Refueling vehicles, commonly called hydrand servicers, are widely used to refuel aircraft. This connects the intake hose to the hydrand valve on the airport's underground pipeline,
This is a special vehicle that operates a pump inside the vehicle body to supply fuel oil to the refueling holes in the main wing of the aircraft via a delivery hose. After refueling is completed at such a Hydland Servicer, the intake hose is removed from the Hydland Valve, hooked onto a hose hanger provided around the vehicle body, and moved to another location. The task of hooking the intake hose to the hose hanger is not easy because the hose is long and heavy, so the applicant developed a device that gives the hose hanger a lifting motion using hydraulic drive in order to hook the intake hose around the vehicle body. (Refer to the specification of Utility Model Application Publication No. 10939/1983).

As shown in FIG. 4, in this device, the base end 1a of an intake hose 1 is connected to the vehicle body 2 of a refueling vehicle, and the tip of this intake hose 1 is connected to a hydrand valve during refueling. After completing the refueling operation, the intake hose 1 is held around the vehicle body 2 by the hose hanger 3. In addition, a lifter deck 4 that can move up and down is installed at the rear of the vehicle body 2, so that when refueling, a worker can connect the refueling port of the delivery hose 5 to the refueling port of the main wing 6 to perform refueling work. .

As shown in FIG. 5, a plurality of the above-mentioned hose hangers 3 are prepared at appropriate intervals around the vehicle body, and each hose hanger 3 is moved up and down by a hose lifting mechanism 7. . In the example shown in FIG. 5, two hose hangers 3, 3 are combined as a set in each section A, B, and C.
One each is arranged on the left and right sides of the vehicle body 2, and one is arranged on the rear side of the vehicle body 2. These hose hangers 3, 3 are connected to three independent hydraulic cylinder devices 8A, 8B and 8C via a hose lifting mechanism 7.
driven by. Each hose lifting mechanism 7 has a sixth
It is configured as shown in the figure. For example, to explain what is shown in section A:
In the illustrated state, the hose hanger 3A is in the lowered position, and when the hydraulic cylinder device 8A is retracted from this state, the rotating arm 9 rotates around the pivot 10 in the direction of arrow M, and the link 11 is pulled up. As a result, the operating rod 12A rotates about the pivot shaft 13 in the direction of arrow N, and the hose hanger 3A at the tip of the operating rod 12A can be lifted to a predetermined height. Therefore, in the state where the hose hanger 3 is lowered, it is easy to set the intake hose 1 after refueling on each hose hanger 3, and after setting, the above-mentioned hose lifting mechanism 7
It becomes possible to set the height to a predetermined height by driving the height.

By the way, the problem with the conventional device described above is that the three sets of hydraulic cylinder devices 8A, 8B, and 8C for the hose hangers are each independent and have one hydraulic power source. A valve is required to synchronize 8B and 8C, and if synchronization is not successful, all hose hangers may not move up and down at the same time, and some hose hangers may not move up or down, or the hose hanger may spring up, causing damage to the hose. be.

[Purpose of invention]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a refueling vehicle in which all hose hangers can be raised and lowered at the same time by raising and lowering a plurality of hose hangers using a single hydraulic cylinder device.

[Summary of the idea]

In order to achieve the above object, the present invention has a plurality of operating rods that can rotate around one end and have a hose hanger attached to the free end, and are spaced apart from each other around the vehicle body. and the tip of a rotating arm that is fixed to a pivot that is rotatably supported on the vehicle body via a bearing bracket and rotates together with the pivot, and is connected with a pin via a link, and is further mounted on the axis of the pivot. Connecting the free end of the fixed drive arm and one end of the drive rod with a pin,
The other end of the drive rod is pin-coupled to the periphery of a turn plate that is rotatable around a support shaft, and the tip of a piston rod of a single hydraulic cylinder device is pin-coupled to the turn plate. Therefore, each hose hanger can be moved up and down in conjunction with each other.

[Example of idea]

The following is a first embodiment of a refueling vehicle according to the present invention.
This will be explained with reference to FIGS. 3 to 3.

In FIG. 1, a pair of hose hangers 3, 3 are arranged in sections A, B, and C on the right, rear, and left sides of a vehicle body 2 of a refueling vehicle, respectively. Incidentally, when it is necessary to specify the members of each section, alphanumeric characters are also written. Each of these hose hangers 3 is fitted onto a vertically erected guide post 14 and is slidable in the vertical direction. FIG. The two-dot chain line indicates the elevated position. As is clear from FIG. 2, the hose hanger 3A is supported via a pin 17 in a long hole 16 of a bifurcated portion 15 at the tip of the operating rod 12A. The other ends of the operating rods 12A are supported by the vehicle body 2 via pivot shafts 13, respectively. Bracket 18 and link 11 on the operating rod 12A
The lower end of the link 11A is connected to the rotating arm 9 via a pin 19, and the upper end of the link 11A is connected to the rotating arm 9 via a pin 20.
are connected by. Rotating arm 9 is pivot 1
0A, and the pivot 10A is rotatably supported by bearing brackets 21, 21. In addition, a drive arm 2 is provided at the center of the pivot shaft 10A.
2 is fixed to the drive arm 22, and one end of a drive rod 24A is pin-coupled to the tip of the drive arm 22 via a pin 23. The opposite end of the drive rod 24A is attached to a pin 2 at one corner of a square turn plate 26 that is rotatable about a support shaft 25.
7. The above configuration consists of a pair of hose hangers 3A and 3A provided on the right side of the vehicle body 2.
Although one set has been described, sections B and C on the rear side and left side of the vehicle body are also constructed of the same material, so a detailed explanation thereof will be omitted. According to the present invention, these remaining sets of drive rods 24B and 24C are each connected to the remaining corner portions of the common turn plate 26 via pins 27B and 27C, respectively. By the way, the operating end of an operating rod 29 of a hydraulic cylinder device 28 is connected to the remaining corner portion of the turn plate 26 by a pin 30, and this hydraulic cylinder device 28 is a single-shaft operated cylinder. The end of the cylinder is fixed to the vehicle body 2 by a pin 31.

Since the present invention is constructed in this way, when the hydraulic cylinder device 28 is driven to cause the operating rod 29 to reciprocate, the turn plate 26 rotates in either direction about the support shaft 25. Then,
Pins 27A, 27B, 2 on turn plate 26
Since rod 7C moves by the same amount of displacement, drive rods 24A, 24B, and 24C are moved by the same amount of displacement in the same direction. Therefore, each drive rod 24
The driving arm 22, the pivot 10, the rotating arm 9,
The operating rod 12 is moved by the same amount in the same direction around the pivot shaft 13 via the link 11, and as a result, all the hose hangers 3 can be moved in the same direction by the same amount in conjunction.

In addition, in FIG. 2, the reference numeral 32 is an upper restraint of the intake hose 1.

[Effects of the invention] As is clear from the above explanation, according to the invention, the turn plate is rotated around the spindle by a single drive cylinder device, and the drive rod is mounted on the circumference of the turn plate. Since the hose hangers are connected together and the movement of the output end of the drive rod moves the operating rod supporting the hose hanger via the link, a plurality of hose hangers can be linked and moved by the same amount in the same direction. Furthermore, since it is driven by a single hydraulic cylinder device, maintenance and inspection can be facilitated and manufacturing costs can be reduced.
