Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gripper attachment device for automatically attaching a gripper to a suspension wire and a cable when the suspension wire and the cable are towed.

[Conventional technology]

Conventionally, a method as shown in FIG. 8 has been known for crossing an aerial cable. First, after suspending the suspension wire 4 on the utility pole 1 of the entire length of the section to be spanned, the cable 6 is temporarily spanned by the guide 2 and the worker rides on the suspension rider 5 on the suspension wire 4 and becomes a gripping body. This is a method of attaching the rings 7 at predetermined intervals. In this case, the ring 7 shown in FIG. 9 is used. As shown in FIG. 9, the ring 7 is inserted from below the cable 6 and the semi-helical portion 73 is hung on the suspension wire 4,
Next, the hook-shaped portion 74 is hung on the suspension wire 4 to hold the suspension wire 4 and the cable 6.

As an improvement method, as shown in FIG. 10, the cable drum 55 and the suspension wire drum 54 are loaded on the vehicle, and the suspension wire 4 and the cable 6 are fed out while the vehicle is slightly moved, and the ring 7 is placed on the ground.
And twist preventive device for preventing twist due to the rigidity of the suspension wire 4
There is a vehicle-towed interposition method in which, while attaching 56, temporary interposition is carried out in sequence by a pulley 57 and a rope 3 passing through the pulley 57 which are previously attached to each telephone pole 1, and after the suspension wire 4 is stretched, the slats are inserted.

[Problems to be solved by the invention]

By the way, the above-mentioned conventional method has a problem in safety due to working at a high place. In addition, the improvement method is limited in some cases, such as when the cable cannot be overridden due to obstacles or the like, or when the vehicle is used and therefore cannot be used due to road conditions. In addition, there is a problem in that workability is poor because the anti-twist device is attached and the rings are manually attached one by one. SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and to provide a gripper attachment device capable of safely performing suspension work between cables and cables with good workability.

[Means for solving problems]

According to the present invention, the above-mentioned problems are caused by a mounting base capable of varying the direction in which the suspension wire and the cable are sent out, a pusher plate movable up and down in a guide plate installed on the mounting base, and the guide plate. A U-block installed on the lower side of the pusher plate in the inside, and a gripping body feed spring capable of moving left and right on a gripping body receiver installed on the side surface of the guide plate, and the gripping body feed spring at the time of crossing. The gripping body on the gripping body receiver is sent out by means of the pusher plate and the U
This can be solved by a gripping body attaching device characterized in that the gripping body is automatically attached to the suspension wire and the cable by the block.

[Action]

According to the present invention, the gripper attachment device is attached to a utility pole adjacent to the utility poles at the ends of a plurality of utility poles that bridge suspension lines and cables at a position where it can be carried by a mount with a caster and operated on the ground. By adjusting the feeding direction of the suspension wire and the cable with the mounting base, the gripping body installed in the gripping body receiver is attached to one end of the gripping body feed spring, and the gripping body is fed one by one to the bottom of the pusher plate, and the pusher plate The gripping body pressed from above by the U on the lower side of the pusher plate.
By holding down with a block, the gripping body is fitted and the suspension wire and the cable are connected.
