Description

Technical Field

[0001] The utility model relates to the technical field of cable traction, and more specifically to a cable traction device. Background Art

[0002] Cable refers to materials used for power, communication and related transmission purposes. It is usually a rope-like conductor made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering.

[0003] When burying cables, the cables need to be passed through special buried pipes to achieve waterproof and anti-corrosion effects. The existing cable traction equipment is pushed from the outside to the inside, and a special spring needs to be put on before pushing to assist, so that the cable can be easily sent into the pipe. This will result in a certain amount of time required to insert and extract the spring. When inserting, the spring is sent in with the traction machine, and when pushing the spring out, the spring needs to be separated from the cable, so it takes a lot of time to pull out the spring, which affects the efficiency of cable traction.

[0004] Therefore, how to provide a cable traction device that is easy to use and can position the cable is a problem that those skilled in the art urgently need to solve. Utility Model Content
