An anti-skid device for electric overhead aluminum stranded wire insulation ladder

Abstract

An antiskid apparatus for an electric power overhead aluminium stranded wire insulating ladder is disclosed. The insulating ladder mainly comprises two ladder rods and multiple ladder pedals made from insulating materials, wherein the insulating ladder is provided with the antiskid apparatus; the antiskid apparatus comprises two channel steel strips that are fixed on the ladder rods through supporting frames on the back surfaces of the channel steel strips respectively, and slot openings are formed in the front surfaces of the channel steel strips respectively; an anti-skid fixed mechanism is mounted in a channel steel internal slot cavity through a spring; the anti-skid fixed mechanism comprises a fixed grasping hook plate with a fixed grasping hook and a movable grasping hook plate with a movable grasping hook, and the fixed grasping hook plate and the movable grasping hook plate are arranged in opposite up and down, wherein the fixed grasping hook plate and the movable grasping hook plate are semicircular bodies respectively, and a fixing ring capable of annularly fixing the electric power overhead aluminium stranded wire in the fixing ring is formed after the fixed grasping hook plate and the movable grasping hook plate are arranged in opposite. The antiskid apparatus has the characteristics of simple structure, convenience in use, low investment, and capabilities of effectively preventing the insulating ladder erected on the electric power overhead line from side sliding, downward sliding, and backward turning, and preventing the electric power overhead line from being damaged due to friction in the use process of the insulating ladder, and the like.

Description

technical field [0001] The invention relates to an anti-slip device for an insulating ladder of an electric overhead aluminum stranded wire, and belongs to the technical field of power line maintenance tools. technical background [0002] During the maintenance of overhead lines, insulation ladders are necessary climbing tools for maintenance personnel. It is often necessary to directly erect insulation ladders on overhead lines for use. However, the structure of insulation ladders currently used is the same as that of ordinary single ladders, and they do not have Anti-skidding, sliding, and backturning functions, and it needs other people to assist in fixing it during use. The most important thing is that the ladder will continue to rub against the line during use, causing line deformation and damage, and more seriously, it is prone to line breakage . Contents of the invention [0003] The object of the present invention is to solve the deficiencies of the above-mentione...
