Controllable anti-disengagement high-voltage power line personal security line

Abstract

A controllable anti-disengagement high-voltage power line personal security line comprises a ground terminal chuck, a hook head and a connecting wire connecting the ground terminal chuck with the hook head. The hook head comprises a hook base and a spring pressing tongue and a control pressing tongue which are oppositely arranged and form a clamping portion; one end of the spring pressing tongue and one end of the control pressing tongue are hinged to the bottom of the hook base separately, the other end of the spring pressing tongue is located on the tail of the hook base, the other end of the control pressing tongue is hinged to a corner joint, a control wire is connected to the corner joint, the hook head comprises a clamping body and a control handle, and the control line penetrates through the connecting wire to be connected with the control handle.

Description

technical field [0001] The invention mainly relates to the technical field of maintenance and protection tools for power outage lines, in particular to the technical field of personal security lines. Background technique [0002] Personal security wires are mainly used on power outage lines of various voltage levels, as a secondary protection in power outage maintenance, through personal security wires to connect the wire end with the iron tower angle steel, to prevent maintenance personnel from being affected by parallel lines, lines erected on the same tower, and crossing Inductive electrical damage caused by lines and insulated overhead ground wires provides reliable protection for maintenance personnel. But the personal security line that uses at present has the following problems during use: [0003] 1. The contact with the wire is not firm, and it is easy to fall off by impact or pulling; [0004] 2. Install two wires of insulating rope and annealed copper rope at th...

AI Technical Summary

Problems solved by technology

[0003] 1. The contact with the wire is not firm, and it is easy to fall off by impact or pulling;

[0004] 2. Install two wires of insulating rope and annealed copper rope at the same time. During installation, annealed copper wire and insulating rope are easily entangled together, which is inconvenient to operate;

[0005] 3. When dismantling, it is necessary to pull the insulating rope to rotate the hook head 180 degrees, which is complicated to operate;

[0006] 4. If the spring piece of the hook head is stuck, the hook head cannot be rotated normally;

[0007] 5. It is inconvenient to pull soft copper wire
