A slip-tooth cable protection device

Abstract

The invention discloses a slip cable protection device, which is wrapped in a pipe body on the outer periphery of the cable. A sleeve adapted to the cable sleeve is arranged between the inner wall of the pipe and the outer peripheral surface of the cable. The middle part is provided with slips that match the inner wall of the tube, and the inner wall of the slips has a guide groove; the sleeve is provided with a swelling block that can move along the axial direction of the sleeve. One end of the expansion block is provided with a pull rod that penetrates and protrudes from the sleeve along the axial direction of the sleeve. The outside of the expansion block has a guide arm that fits into the guide groove. The guide arm The distance from the expansion block gradually increases from one end where the pull rod is located to the other end. The slip-tooth cable protection device has better protection effect on cables and has higher safety.

Description

technical field [0001] The invention relates to the technical field of supporting equipment for erection and maintenance of power transmission and transformation lines, in particular to a slip cable protection device. Background technique [0002] In the current line erection and maintenance process of power transmission and transformation systems, cables are an extremely important part. During the erection process, cables are usually buried underground to save surface space and improve the integration of wiring harnesses. With the continuous improvement of the demand for use, people have also put forward higher requirements for the structural protection of the cables after they are buried. [0003] During the erection of current power transmission and transformation lines, the cables are usually bundled and then penetrated into the cable conduits buried underground. Although these conduits can meet the basic protection needs of cable structures, due to their relatively simp...

Problems solved by technology

[0003] During the erection of current power transmission and transformation lines, the cables are usually bundled and then penetrated into cable conduits buried underground. Although these conduits can meet the basic protection needs of cable structures, due to their relatively simple structure, they usually only have a single Therefore, the structural protection strength of the cable is poor, and because the structure between the inner wall of the tube and the cable is relatively loose and simple after assembly, the buried cable is very easy to be pulled out by criminals and dragged to the surface to carry out theft. It not only restricts the safety of cables and wires, but also adversely affects the operation stability and continuity of the entire power transmission and transformation line
