The traveling machine 7 and the winding machine 5 can be remotely controlled, and reference numeral 51 in FIG. 1 indicates an antenna provided for transmitting and receiving control signals.

Next, a method of winding the preformed rod group l around a predetermined position of the cable 3 using the winding device 4 configured as described above will be explained.

Before attaching the winding device 4 to the cable 3, on the ground, the m-section fixing fitting 2 of the preformed rod group 1 is attached to the gripping tool 18 of the rod group clamping mechanism 8, and the preformed rod group 1 is attached to the gripping tool 18 of the rod group clamping mechanism 8.

The free end side of the cable group 1 is divided into one or several rods and inserted into each rod insertion hole 33 of both rotary disks 12A-12B to disperse them in the circumferential direction of the cable 3.

Then, a winding device 4 is attached to the cable 3, and the traveling machine 7 is driven by remote control from the ground to arrange the winding machine 5 at a desired position. Next, both clamp mechanisms 8 and 13 of the winding machine 5 are driven to fix the end fixing fittings 2 of the preformed rod group 1 to the surface of the cable 3, and the fixing plates 15 of both supports 10A and 10B are It is fixed near both ends of the wrapping range of the preformed rod group 1.

Then, when the drive section 19 of the winding mechanism 9 is brought into a driving state, both the rotary disks 12A and 12B rotate together with the frame 11 as shown by the arrow (A) in FIG. The preformed rod group 1 inserted into the rod insertion hole 33 of 12A-12B is wound helically around the surface of the cable 3, and is pushed by the rotary disk 12A or the preformed rod l wound helically. While pointing the arrow (b) along the guide shaft 31
As shown in the figure, the preformed rod group 1 is moved rearward and wound over a predetermined winding range. In this case, the holding rotary disk 12B is pushed by the winding rotary disk 12A to move rearward.

By screwing into the threaded member 42, the winding operation can be performed effectively. That is, the resistance force of the preformed rod group 1 against winding is greatest near the end of the winding, and therefore
Although A tends to slip and shift in the length direction of the cable 3, the occurrence of this shift is regulated by the screw engagement between the male threaded member 41 and the female threaded member 42. Therefore, it is considered that the threading pitch between the male threaded member 41 and the female threaded member 42 should be the same as the required winding pitch, but since the threaded state is only at the end of the winding, this is not necessarily the case. The pitches do not have to be the same, as long as the occurrence of deviation can be controlled.

When the winding work is completed in this way, both clamp mechanisms 8 and 13 are released, the traveling machine 7 is moved to a required position, and the device 4 is removed from the cable 3.

(ii) The tightening device according to claim 2 regulates the sliding movement of the rotary disk, which becomes easy to slip due to the increased resistance at the end of the winding, by screwing the male threaded member and the female threaded member. It is possible to reliably wrap the preformed rod group up to the final end.

(iii) Since the winding device according to KW claim 3 can move the winding mechanism etc. to any position by means of a traveling machine, the winding work can be carried out without the need for a worker to ride in the air on the cable, and it is safe as well. , it is possible to achieve complete automation.
