題があった。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The vehicle for exchanging a switch according to the above-mentioned conventional example is useful. However, it is difficult to remove and mount the switch without interfering with the switch mounting bolts implanted at the installation position and the mounting holes provided in the switch. In other words, the work arm has a configuration in which the base end side work arm is undulated, and the tip side work arm is bent to hang and hang the switch through the hook, and the base end side work arm is undulated and the tip side work arm is bent. This is because the switch being suspended moves along an arcuate trajectory. Therefore, during the replacement work of the switch, it is necessary to pay close attention to avoid damage to the switch mounting bolt (it becomes impossible to screw the nut) due to interference of the mounting holes. There is a problem to be solved that not only it takes a long time for the installation work, but also the mental labor for the workers is great.

い。When the work for removing the switch to be replaced is completed, the swinging device 2 swings the suspension arm 3 to suspend the repaired or new switch mounted on the loading platform 1a, and swinging device. The suspension arm 3 is swung by 2 and then the undulating cylinder 3c and the bending cylinder 3d are operated to move it to a position directly above the installation position, that is, a position where the switch mounting bolt and the switch mounting hole are aligned. Move the ruts. When the rod 4b of the hydraulic cylinder 4a is extended, the switch T can be hung vertically without moving laterally as in the conventional case, so that the bolt hole does not interfere with the switch mounting bolt. .

a, and as shown in FIG.
c and the rod of the bending cylinder 3d are reduced to make the base end arm 3
While making a horizontal, the front end arm 3b is folded so that the base end arm 3a side crosses the platform 1a, and the track running wheels 1d travel on the tracks R, R to return to the target position. Then, after that, by returning to the repair shop by self-propelled by the crawler belts 1b, 1b, operating the suspension arm 3 again to unload the removed switch to be repaired from the carrier 1a,
A series of operations related to transportation of repaired or new switches, replacement of switches, and recovery of removed switches are completed.

定されるものではない。In the above description, the example in which the hook device is attached to the vehicle for exchanging the switching device which can freely travel on the track and on the track has been described. However, the exchanging operation of the switching device having the bending suspension arm is possible. Since the technical idea of the present invention can be applied to a vehicle, the scope of the technical idea of the present invention is not limited by the above embodiment.
