Tool for replacing cotter pin of power transmission line

Abstract

The invention discloses a tool for replacing a cotter pin of a power transmission line, belongs to the technical field of the tool for replacing the cotter pin of the power transmission line, and aims to solve the technical problems by providing the tool for replacing the cotter pin of the power transmission line, wherein the tool is simple in assembled structure, quick and convenient to operate, time-saving in replacement and high in efficiency. A technical scheme for solving the technical problems is adopted as follows: the tool comprises a contact part, an adjustment part and a fixed part; the contact part is movably arranged in the adjustment part in the axial line direction; one end of the adjustment part is rotationally connected with one end of the fixed part; the contact part extends in the radial direction to form a section of clamping plate; the adjustment part extends in the radial direction to form a section of baffle; the contact part is a solid columnar body, wherein one end is a claw-back extension end while the other end is a solid end; and a section of through groove is formed in the solid end in the axial line direction. The tool can be widely applied to the field of the power transmission line.

Description

technical field [0001] The invention relates to a tool for replacing cotter pins of power transmission lines, belonging to the technical field of tools for changing cotter pins of power transmission lines. technical background [0002] There is a shortage of spring pins and corrosion of spring pins in the electrical parts of high-speed railways, expressways, and old high-voltage transmission lines. When the spring pin is added, it is carried out according to the conventional live working standard, and it needs to be completed by using an insulating tool to enter the potential operation; usually, the replacement of the spring pin in a high-voltage transmission line such as 35kV-220kV adopts a general replacement method, and the operation efficiency is low. The working hours are longer and the labor intensity of the operators is higher. At this time, according to the needs of the actual situation, it becomes very urgent to develop a new type of replacement tool and improve the...
