BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a remote control car for cable wiring according to the present invention; FIG. 1 is a perspective view of a remote control car. The remote control car 1 has a known internal structure, and although not shown, includes a radio wave receiving unit, a driving unit, a power supply unit, and a control unit for controlling the driving unit. The axles 3a and 3b are pivotally supported at the lower part of the remote control car main body 2 back and forth,
The rear axle 3b is selected as a drive shaft, and is connected to the drive unit via a gear (not shown). Each axle 3
Wheels 4 and 4 are mounted on both ends of a and 3b, respectively, and further, caterpillars 5 and 5 are installed between the wheels 4 and 4 at front and rear positions. The caterpillars 5 and 5 have a length that does not fall off the upper surface of a cable rack 11 described later, and run by biting the beam 13. A thread spool 6 is provided on the upper surface of the remote control car main body 2 near the rear. The bobbin 6 has a rotatable winding shaft 8 horizontally supported between a pair of support rods 7, 7, and a winding thread 9 is wound around the winding shaft 8. Reference numeral 10 denotes an antenna protruding from the radio wave receiving unit. The remote control car 1 can be freely driven by remote control by a controller (not shown). The thread winding 6 can be synchronized with the running speed of the remote control car 1 by assembling a clutch mechanism (not shown) on the winding shaft 8 or the running thread 9 can be automatically unwound. It is good also as composition.

[0006] A method of wiring cables on the upper surface of a cable rack suspended at a high place on the ceiling using the remote control car 1 configured as described above will be described. FIG. 2 shows the cable rack 11 assembled in a flat rectangular shape. The cable rack 11 is formed in a ladder shape by arranging beams 13 at equal intervals between two parallel main body frames 12, 12, and the remote control car 1 runs when the caterpillars 5, 5 bite the beams 13. . The cable rack 11 is usually suspended from the ceiling by a hanger fitting (not shown). The gold wheels 1 are located at corners C1 to C4 where the straight sections S1 to S4 intersect.
4 are installed. This wheel 14 has a pulley shape as shown in FIGS. 3 and 4, the base end of the handle 15 is fixed to the inside of the outer main body frame 12, and a rotating wheel is attached to the bifurcated portion at the tip. The shaft 16 is supported horizontally, and the warp yarn 9 is wound around the circumferential groove 17 of the rotating wheel 16.

[0007] Therefore, first, the worker places the remote control car 1 on the corner C1 at one end of the straight section S1 of the cable rack 11 on which the worker climbs the ladder, and in this state, a length corresponding to the straight section S1 is provided at the tip of the road thread 9. Connect the rope 17
A cable 18 is further connected to the end of the rope 17. Then, the operator operates the controller (not shown) on the ground to move the remote control car 1 toward the corner C2 at the other end as shown in FIGS. As a result, the road thread 9 is sent out from the thread spool 6 as the remote control car 1 travels. The remote control car 1 is stopped when it reaches the corner C2. Next, at the corner C2, the worker climbs on the ladder, pulls the string 9 around the rotating wheel 16 of the wheel and pulls it, pulls the string 9, the rope 17 and the cable 18 in order, and passes the cable 18 in the straight section. It is wired on the upper surface of the cable rack 11 of S1.

Further, the straight section S1 of the cable rack 11
When extending the cable 18 wired to the straight section S2 and thereafter, the same operation as that performed in the straight section S1 is repeated for each of the straight sections S2 to S4 while wrapping the warp yarn 9 around the rotating wheel 16. Cable 1 at desired location
8 can be wired sequentially.

In the cable routing method of the present invention in which the cable 18 is wired on the upper surface of the cable rack 11 using the remote control car 1, the controller is operated on the floor to move the remote control car 1 to the cable rack 11. The upper surface may be run for a predetermined distance and stopped, and the operator may sequentially pull the thread 9, rope 17 and cable 18 sent out at this location. For this reason, the construction becomes easy, and not only the labor is reduced, but also the working time can be shortened and the working efficiency is improved. In addition, the number of times the worker moves up and down the cable rack 11 suspended at a high place can be reduced, and the worker hardly needs to walk on the upper surface of the cable rack 11 to reduce danger and improve safety. .
It is needless to say that the cable wiring method of the present invention can also be adopted for a cable wiring method in an underground pipe.

[0010]

As described above, according to the present invention, the remote control car for cable wiring can be raised by remote control from the floor surface, with the rope and the cable being sequentially connected to the end of the yarn wound on the bobbin. The remote control car is placed on the upper surface of the cable rack suspended at a high place on the ceiling, and is run by remote control from the floor surface. When the operator stops and stops, the operator can pull the yarn, rope and cable in order, so that the cable can be routed on the cable rack. Work efficiency is significantly improved. Furthermore, work at heights is reduced, danger can be reduced, and safety is improved.
