Electric transmission line climbing portable fall preventing tool

Abstract

The invention discloses an electric transmission line climbing portable fall preventing tool. The tool comprises a fall preventing body, and a safety rope with buckle rings at the two ends; the fall preventing body comprises a handle, and an automatic locking and clamping head; the safety rope is hooked on the fall preventing body; the automatic locking and clamping body is a waist-shaped plate body, and is provided with an arc angle rhombic hole in middle; the top angle of the rhombic hole upwards extends to form an arch top; an arch groove is formed in the inner wall surface of the waist-shaped plate body; transverse holes penetrating through the side walls of the waist-shaped plate body are symmetrically formed in the two sides of the arch groove; ball grooves for assembling fixed pressing pieces are symmetrically formed in the outer wall surfaces of the two sides of the waist-shaped plate body; eagle mouth turning plates with inward openings are symmetrically arranged in the arch groove, and are fixed in the arch groove by positioning balls; the back parts of the eagle mouth turning plates are fixedly connected with return springs penetrating through the transverse holes; the outer ends of the return springs are connected with the fixed pressing pieces; and the fixed pressing pieces are connected to the waist-shaped plate body. The tool is small and portable, is convenientto use, and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of safety protection tools used for power transmission line tower inspection and fall prevention in power systems. Background technique [0002] In the prior art, it is necessary to climb the transmission line iron tower when checking and repairing the transmission line. According to the "China Southern Power Grid Co., Ltd. Electricity Safety Work Regulations" 3-20.2.2, the protection of the safety belt should not be lost when climbing the pole tower and transferring the position. During driving, always check whether the seat belt is fastened. At present, the commonly used anti-fall tools are anti-fall double extension protection ropes and double-hook protection anti-fall tools. Exposure to open flame. [0003] The anti-fall double extension protection rope is currently the most commonly used safety protection tool for anti-falling when climbing a tower. When climbing the pole tower, the first extended pr...

AI Technical Summary

Problems solved by technology

The disadvantage of the double extension protection rope for anti-falling is: the climbing tower personnel must have very good physical strength, and need to repeatedly untie and hang the extension protection rope. The development of the operation caused problems such as physical exhaustion of the climbers

The disadvantage of the double-hook protection anti-fall tool is: the climber must have very good strength, and needs to repeatedly press down the safety bolt of the first hook to hang it on the main material of the angle steel. It is not conducive to the development of high-altitude operations, causing problems such as physical exhaustion of climbers

However, in the existing tower climbing and falling prevention tools, there is a problem of weak practicability, and it does not have the ability to reduce physical exertion in time when a dangerous situation occurs. necessary
