A self-tightening rod climbing device

Abstract

The invention provides a self-tightening rod climbing device, which comprises a regulating clamp element, a first holding ring, a second holding ring, a pedal, a piston plate, a positioning plate, a clamp foot, anti-slip rubber, a slide groove, a positioning rod, a linkage rod, a stressed plate, a clamping and connecting edge, a hollow groove, an anti-slip threaded plate and a passive plate, wherein the upper and lower sides of the regulating clamp element are movably connected with the first holding ring and the second holding ring through screw bolts; the anti-slip rubber is arranged on thesurface of the first holding ring in an embedded way; the piston plate, the positioning plate and the clamp foot are sequentially arranged inside the second holding ring from the outside to the inside. The back surface of the passive plate is an inclined surface, and the inclination direction is opposite to the inclination direction of the stressed plate, so that the position of the piston plate cannot be changed; the passive plate is extruded by force and extends outwards; further, the anti-slip threaded plate is used for realizing the contact with the rod; meanwhile, the tight clamping of the anti-slip threaded plate on the rod is realized; the self-tightening goal is achieved. By using the arrangement, the self weight of the user is used for clamping, so that the device is safer in theuse process.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a self-tightening pole climbing device. Background technique [0002] As we all know, power transmission generally adopts high-hanging wires or buried wires. Due to the large amount of construction, high cost of line laying, and inconvenient maintenance, buried wires are only used in factories, schools and living quarters in cities. Most transmission lines There are two types of high hanging wires, one is tower type, the other is pole type. The pole type is widely used because of its convenient construction, small footprint and safe use. The rod climbing device adopts the helical arc clamping method; [0003] The pole climber uses leverage, with the help of the body's own weight, to make the other side tightly fastened to the pole to generate greater friction, making it easier for people to climb. [0004] Based on the above description, and in combination with the equi...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a self-tightening pole climbing device to solve the problem of insufficient safety factor when used for a long time due to the frictional fit, which is usually a passive fit, and the pole is a column whose diameter gradually decreases from bottom to top. When climbing a pole, the user needs to constantly adjust the inner diameter of the pole climber to adapt to the diameter of the pole. At the same time, the existing device is subjected to a single point of force when it is in contact with the pole body, which makes the pressure distribution not uniform enough to operate cumbersome questions
