[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable trolley used for bridging electric wires (cables) between utility poles.

[0002]

2. Description of the Related Art Conventionally, in the work of bridging a cable between telephone poles, a cable wound on a cable drum is fed from a starting point side of a bridging section, and a tip of the cable is arranged at an end point side of the bridging section. Had done by towing by winch. In addition, a worker on a work platform of an aerial work vehicle moved to the upper part of the utility pole and attached the cable to the utility pole on which the cable was bridged.

[0003]

[Problems to be Solved by the Invention] However, such a method of laying a cable has a problem in that work efficiency is poor, and that the work needs to be moved to a high place, which poses a danger to the work. there were.

[0004] The present invention has been made in view of such a problem, and an object of the present invention is to provide a cable trolley capable of performing a cable laying operation efficiently and safely. And

[0005]

In order to achieve the above object, the cable trolley of the present invention has a first boom that can be raised and lowered on a vehicle body, and a first boom is provided at the tip of the first boom. And a cable holding device for holding a cable. In addition, a manipulator device that can be remotely controlled is provided at the tip of a second boom that is mounted on the vehicle body so as to be able to move up and down. Further, on the front, rear, left and right sides of the vehicle body, there is provided a vehicle body supporting and traveling device configured to include rotatable work wheels at a lower end grounding portion of a jack for supporting the vehicle body with respect to the ground.

[0006]

In such a cable cruising vehicle, the first boom is appropriately raised and lowered to raise the cable holding device holding the cable to an appropriate height. At the same time, while the vehicle body is supported and stably supported by the vehicle body supporting and traveling device, the working wheels are rotated to move the vehicle body. Thereby, the cable can be pulled at a high place. Then, the manipulator device, which has been moved to a high place by the raising and lowering operation of the second boom, assists in pulling the cable through remote control from the vehicle body, for example, or attaches the cable to a utility pole on which the cable is bridged. It is possible to smoothly carry out the work of laying the cable while performing the work.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the cable trolley 1 according to the present invention is configured based on a vehicle body 2 of a truck. Swivel tables (first swivel table 13 and second swivel table 23) that can freely turn horizontally with respect to the vehicle body 2 are attached to the front part (however, the rear part of the driving cabin 2a) and the intermediate part of the vehicle body 2 respectively. .

A first boom 14 which is telescopically extendable and retractable is pivotally mounted on the upper portion of the first turntable 13 so as to be able to move up and down. A cable holding device 15 capable of holding (gripping) the tip of the cable C or the like is attached to the tip of the first boom 14.

On the other hand, on the upper part of the second swivel table 23, a second boom 24, which is telescopically extendable and retractable, is pivotally mounted so as to be able to move up and down. A manipulator device 25 is attached to the tip of the second boom 24. The manipulator device 25 includes the manipulator arm 2
5a and a television camera (for example, a stereoscopic camera) 2
5b is provided. This manipulator arm 25
The operation of the work cabin 2 provided at the rear of the vehicle body 2
The operator boarding in the area b can remotely control the image while watching the image taken by the television camera 25b.

[0010] At four positions on the front, rear, left and right sides of the vehicle body 2, vehicle body supporting and traveling devices 30 are respectively attached (however, only those on the left and front sides of the vehicle body 2 are shown in the figure). The vehicle body supporting and traveling device 30 includes an outrigger jack 31 that is capable of extending the vehicle body 2 to the side and extending downward, and for stably supporting the vehicle body 2 on the ground by grounding its lower end. Be prepared. However, a work wheel 32 that is rotatable by hydraulic pressure is attached to the lower end grounding portion of the outrigger jack 31. By rotating the work wheel 32 to ground and rotating, the vehicle body 2 is stabilized. (The running wheels of the truck are slightly raised from the ground). Since the working wheels 32 are steerable, the vehicle body 2 can be turned by the vehicle body supporting and traveling device 30.

The cable trolley 1 configured as described above.
When the work of bridging the cable C to the utility pole D is performed, first, the vehicle body 2 is supported by the vehicle body supporting and traveling device 30, and the distal end of the cable C is attached to the cable holding device 15 in a low place such as on the vehicle body 2. Hold. Note that the cable C is fed from a cable drum (not shown) arranged on the starting point side of the bridging section.
Then, the turning operation of the first turning table 13 and the first boom 1
The tip of the cable C is lifted up to the vicinity of the bridging height by the undulating / expanding operation of 4.

Next, the work wheel 32 of the vehicle body supporting and traveling device 30 is operated to connect the cable trolley 1 to the cable C.
In the direction of the bridge. As a result, the cable C is pulled in the same direction, and is drawn out to the vicinity of a telephone pole (hereinafter, referred to as a pre-crossover telephone pole) D 'provided on the front side. here,
If the cable C is towed as it is, the tow cannot be continued because the cable holding device 15 interferes with the utility pole D 'before the bridge. For this reason, when crossing the telephone pole D 'before the bridge, for example, the cable C is temporarily held by the manipulator arm 25a instead of the cable holder 15, and the cable pole D' before the bridge. Is moved to a position beyond the utility pole D '. Thereafter, the manipulator arm 25a is operated to cause the cable holding device 15 to hold the cable C again.

The cable C is attached to the electric pole D 'at the point when the electric pole D' before the crossover is passed. The attaching operation is also performed using the manipulator arm 25a. As a result, the worker does not need to perform the mounting work, which is conventionally performed by climbing to a high place (in many cases, moving on a work platform of a high work vehicle) as in the related art, and efficiently and safely (for example, (There is no danger of the operator falling into an unstable state on the workbench).

[0014]

As described above, in the cable trolley of the present invention, the cable is held by the cable holding device attached to the tip of the first boom, and the vehicle body is moved by the vehicle body supporting and traveling device. Thereby, the cable can be pulled at a high place. Further, the manipulator device attached to the tip of the second boom can assist the pulling of the cable through remote control, or can perform the work of attaching the cable being pulled to the utility pole. For this reason, the work of bridging the cable to the utility pole can be performed efficiently, and the work can be performed safely because the worker does not need to climb high places.
