Pole holding mechanism for manned pole climbing operation platform

Abstract

The invention discloses a manned pole climbing operation platform and a pole holding mechanism thereof. The pole holding mechanism comprises a cantilever and a tail end pole holding mechanical arm. The tail end pole holding mechanical arm comprises a front clamping jaw, a rear clamping jaw, a front fulcrum rotating shaft, a rear fulcrum rotating shaft, a front thrust nut composite rotating shaft,a rear thrust nut composite rotating shaft, a right-hand thread screw, a left-hand thread screw, a kinetic energy striking type spiral pre-tightening device and a pressure sensor. The front clamping jaw, the rear clamping jaw and the cantilever are hinged through fulcrum rotating shafts. The kinetic energy striking type spiral pre-tightening device is used for driving the positive thread screw andthe negative thread screw to rotate synchronously. The positive thread screw and the front clamping jaw are hinged through a front thrust nut composite rotating shaft, the negative thread screw and the rear clamping jaw are hinged through a rear thrust nut composite rotating shaft, and the front clamping jaw and the rear clamping jaw are oppositely opened or closed so as to clamp or separate froman electric pole. The pole holding mechanism can tightly hold an electric pole within a certain diameter range, and has enough pole holding force so as to ensure the safety of manned pole climbing.

Description

technical field [0001] The invention relates to a working platform for climbing up and down poles and columns, in particular to a manned pole climbing work platform and a rod grip mechanism for the manned pole climbing work platform to replace the commonly used pole climbing tool "foot". buckle". Background technique [0002] In the electric power industry, maintenance of power lines by climbing towers is an indispensable link, and its standardized operation is directly related to the personal safety of operators and the safe operation of the power system. Especially in recent years, accidents of personal injury and death in pole climbing operations have occurred frequently. [0003] At present, the most commonly used pole climbing tool is the foot buckle. [0004] (1) When the foot buckle is officially used, professional training must be provided to the climbing staff. Because the user needs to find the balance of the conversion of the alignment force, the up and down co...

AI Technical Summary

Problems solved by technology

[0005] (2) Whether the foot buckle can be fastened to the pole is completely controlled by the operator, and it is all judged by personal experience, and the safety and reliability are low;

[0006] (3) The way of climbing the pole with the foot buckle has high labor intensity, short standing time, great physical exertion, and is easy to cause fatigue

This makes the climbers feel heavy and panic when they are working, and it is easy to cause inattention and accidents.
