In any case, the support 20 can be engaged with the support wires 12 on both sides of the mooring portion 16 and the like, and the special wheel drive device 22 can be stably supported. In particular, by configuring the horizontal frame 32 of the support body 20 with the telescopic frame device 96, the support frame can be attached to the support line by extending it long when the mooring internal angle is large and shortening it when the mooring internal angle is small. Easier to remove. As shown in FIG. 7, even when the support wire 12 or the like is not moored to the utility pole 14 and is simply stopped by the stop wire 106, the support wire 12
The hooks 74, 74 of the support 20 can be engaged with the supporting member 20 to stably support the wheel drive device.

Therefore, at the position where the support wire 12 and the like are bent and moored to the utility pole 14, there is no need for the worker to climb on the utility pole and perform high-altitude work in order to mount the special wheel device 22 on the utility pole side. The rod and the tow rope can be efficiently mounted in a short time by operating the rod, and the number of times the operator climbs the telephone pole is reduced, so that a fall accident or the like does not occur and the safety of the operation is increased.

As described above, the wire wheel device 22 is attached to the support wire 12 or the intermediate position of the existing cable, or to the utility pole 14 or another utility pole where the support wire is bent and moored, and the wiring of the guide rope is completed. Then, the guide rope 104 is connected to the cable wound around the drum on the cable feeding side, and the guide rope 104 is connected to the winch and pulled on the pulling side, and the cable is drawn into each wheel wheel device. Thereafter, the worker climbs on each utility pole, tensions the cable to a specified tension by using a wire tensioner or the like, and holds the cable to each utility pole by a winding grip or the like. After the cable is fastened to each pole, the support wire 12
The intermediate wheel device 48 attached to the intermediate position of (1) draws toward one telephone pole using the operating rod. Then, a worker climbs each telephone pole 14, removes the pulley device 22 attached to the telephone pole from the cable, collects it from the ground using the operating rod 92 together with the support body 20 to the ground, and pulls it to the pole base. The wheel drive device 48 is also removed from the cable at the same time and collected, and the operation is completed.

In this embodiment, a separate type cable for locking the cable to the support wire 12 is exemplified by a case in which a special wheel drive device is attached to the utility pole side where the support wire is bent and moored. However, the present invention is not limited to this, and even in the case of an integrated cable in which a support wire is provided inside a cable, the support device 1 of the wheel and pinion device can be used in the case of replacing an existing cable.
0 can be used to mount the wheel drive device. Further, the support device of the wheel drive device with respect to the support wire according to the embodiment of the present invention can be used in a construction site or a cableway site, in addition to the attachment of the wheel drive device for stretching cables such as power lines and communication lines. The workability and safety can be improved by utilizing it for the work of mounting a wheel drive device that supports various cords and the like.
