Description

The present invention relates to a device for wrapping a preformed rod, such as a pre-formed spiral armor rod, around a cable.

“Prior Art” Conventionally, the work of winding a preformed rod such as an armor rod around a cable is performed manually by an operator who rides on the cable in midair.

"Problems to be solved by the invention" However, the winding work by hand requires the skill of the worker, and the work at a high place to be carried out in the air is unstable and dangerous, which causes the worker to be very tired. There is a problem in safety management.

The present invention effectively solves the above problems, and an object thereof is to automate the operation of winding a preformed rod.

"Means for Solving the Problem" The winding device according to claim 1, wherein a clamping mechanism that fixes one end of the preformed rod group to the cable surface,
A winding mechanism that winds around the cable while rotating the free end side of the preformed rod group whose one end is held by the clamp mechanism around the cable,
The winding mechanism, a pair of support tools arranged at a distance larger than the length of the preformed rod group, and a frame body provided between the pair of support tools so as to rotate around a cable, A turntable having a rod insertion hole which is movably supported along the length of the cable and is supported by the frame body and which divides a group of preformed rods into one or several pieces and disperses them in the circumferential direction of the cable. Of the support, which is disposed near the winding end of the preformed rod group, and the rotary disk, which are screwed together by the rotational force acting on the rotary disk. It is characterized in that a male screw member and a female screw member are provided.

The winding device according to a second aspect of the invention is characterized in that the traveling mechanism that moves along the cable is provided with the clamp mechanism and the winding mechanism.

[Operation] In the winding device according to the first aspect of the present invention, one end of the preformed rod group is fixed to the cable surface by the clamp mechanism, and a frame is supported by a support tool in the vicinity thereof, and the frame is supported by the frame. One or several preformed rod groups are inserted into the rod insertion holes of the rotating disc, and the preformed rod groups are inserted into the rod insertion holes so that they are dispersed in the circumferential direction of the cable. Then, when the frame body is rotated, the preformed rod group is wound around the cable by the turntable that rotates integrally with the frame body, and the turntable is pushed as the winding of the preformed rod group progresses. Since the cable is fed along the frame in the length direction, the preformed rod group having a predetermined length can be spirally wound around the cable by the rotational movement and the linear movement of the turntable. In this case, the preformed rod group is inserted into the rod insertion hole of the rotary disk by dividing the preformed rod group into one piece or several pieces, and is dispersed in the circumferential direction of the cable, so that they are not entangled with each other. It is neatly wrapped.

Then, in the vicinity of the winding end end of the preformed rod group, the rotary disk and the support are connected by the male screw member and the female screw member. The vicinity of this end of winding is the portion where the resistance of the preformed rod to the winding force is the largest, and the resistance makes it easier for the rotating disk to slip and shift in the lengthwise direction. The occurrence of the deviation is regulated by the screwing.

In the winding device according to the second aspect, the winding mechanism can be moved to a target position of the cable by the traveling machine and the winding work can be performed at that position.

Next, a method of winding the preformed rod group 1 around a predetermined position of the cable 3 by the winding device 4 configured as described above will be described.

Before attaching the winding device 4 to the cable 3, the end fixing fitting 2 of the preformed rod group 1 is attached to the grasping tool 18 of the rod group clamp mechanism 8 on the ground, and the preformed rod group 1 The free end side is divided into one or several pieces, and each rod insertion hole of both turntables 12A and 12B

Then, the winding device 4 is attached to the cable 3, the traveling machine 7 is caused to travel by remote control from the ground, and the winding machine 5 is arranged at a target position. Then, 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 to fix the fixing plates 15 of both supporting tools 10A and 10B. The preformed rod group 1 is fixed near both ends of the winding range.

Then, when the drive unit 19 of the winding mechanism 9 is brought into a driven state, both the rotary discs 12A and 12B rotate together with the frame 11 around the cable 3 as shown by the arrow (a) in FIG. The preformed rod group 1 inserted into the rod insertion holes 33 of 12A and 12B is spirally wound around the surface of the cable 3, and the turntable 12A is pushed by the preformed rod 1 which is spirally wound. Meanwhile, the preformed rod group 1 is wound along a predetermined winding range by moving backward along the guide shaft 31 as shown by an arrow (B).

The occurrence of the deviation is regulated by the screw engagement with the female screw member 42. Therefore, it is considered that the screw pitch between the male screw member 41 and the female screw member 42 should be the same as the required winding pitch, but since the screwing state is limited to the winding end portion, it is not always the same. It does not have to be the pitch, as long as it is possible to regulate the occurrence of displacement.

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

"Effects of the Invention" As is apparent from the above description, the winding device for a preformed rod group according to the present invention can achieve the following effects.

(I) In the winding device according to the first aspect of the present invention, the preformed rod group is divided into one or several groups and inserted into the rod insertion holes to disperse in the circumferential direction of the cable. By the linear movement along the frame of the rotating disk, the preformed rod group can be spirally wound around the outer circumference of the cable in an orderly manner, and it is possible to automate most of complicated winding work without requiring skill. Also, at the end of winding, the sliding movement of the turntable, which becomes slippery due to an increase in resistance, is regulated by the screwing of the male screw member and the female screw member to ensure the end of the preformed rod group. Can be wrapped.

(Ii) In the winding device according to the second aspect, since the winding mechanism and the like can be arbitrarily moved to a position by the traveling machine, the winding work can be performed even if the worker does not ride on the cable, which is safe. It is possible to achieve full automation.
