Description

[Detailed Description of the Invention] Object of the Invention (1) Field of Industrial Application This invention relates to a hanging device for hanging a communication cable with a single support wire from a utility pole via a support wire, and a method for hanging the same. It is something.

(2) Conventional technology Conventionally, when suspending a communication cable with one support wire from a utility pole, the cable support wire was clamped into the receiving groove of the horizontally long front and rear clamping plates, and the front and rear clamping plates were bolted together. The locking bolt is passed through the bolt hole drilled in the suspension device consisting of the front and rear clamping plates, and the support wire is pulled toward the utility pole using a wire tensioner or rope, and then attached to the utility pole. The bolts of the suspension fixture are screwed into the drilled bolt holes for fixing the suspension fixture to secure the suspension fixture to the utility pole, while the communication cable is suspended using the support wire.

(3) Problems to be Solved by the Invention However, when installing the support wire on the utility pole, the support wire is fixed to the utility pole under tension, so it is difficult to adjust the fixing position. This required two people: one to pull the hanging equipment to the telephone pole, and another to secure it to the utility pole with bolts, making the work long and dangerous. In addition, two types of hanging equipment are required, one for straight lines and one for curved lines, which poses difficulties in material management.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide a horizontal plate with a receiving groove for the support line and front and rear receiving plates protruding to prevent the support line from coming off. After fixing the hanging rack holder at a predetermined position on the utility pole, and transferring the cable support wire into the receiving groove of the holder, fit the holding plate into the hanging rack holder and secure it with bolts and nuts. It is designed to clamp and lock the cable support wire while stopping the cable, making it easy to fix and adjust the suspension equipment, allowing a single worker to perform the work with high efficiency, and preventing the support wire from coming off during work. To provide a hanging device and a hanging method for a cable support line, which are safe, can be used for both straight lines and curved lines, and can simplify material management work.
