Tool for replacing vibration damper of power transmission line

Abstract

The invention discloses a tool for replacing a vibration damper of a power transmission line, the tool comprises a length-adjustable transverse ladder, a length-adjustable vertical ladder, a roller, a clamping seat and a steering hook, the vertical ladder is fixed at one end of the transverse ladder, the roller and the clamping groove seat for clamping the line are respectively fixed at two ends of the transverse ladder, and the steering hook is fixed at one end, far away from the transverse ladder, of the vertical ladder. The tool has the advantages that the roller and the clamping groove seat on the transverse ladder are clamped and placed on a line, the transverse ladder is prevented from shaking on the line, after the length of the vertical ladder is adjusted according to the length of an insulator, the steering hook is hung on a cross arm, the tool is made to be stable, and therefore an operator can easily go down to the transverse ladder from the cross arm through the vertical ladder; and the length of the transverse ladder is adjusted to a proper position according to the position of the damper on the line, and finally the position of the damper is reached through the transverse ladder, so that the damper can be replaced and mounted, the operation danger is reduced, and the working efficiency is also greatly improved.

Description

technical field [0001] The invention relates to the technical field of power transmission line maintenance tools, in particular to a tool for replacing a power transmission line anti-vibration hammer. Background technique [0002] During the operation of power line towers, the anti-vibration hammer of the line is an essential accessory. It is used to prevent excessive vibration of the wire and protect the line. The anti-vibration hammer also has a service life cycle. After reaching the service life, it must be removed as soon as possible to avoid failure The purpose of vibration, but also to prevent the anti-vibration hammer from falling from above and hurting passers-by. [0003] At present, in the construction and maintenance of transmission lines in the power industry, it is very common to install and replace anti-vibration hammers, but now about 95% of the straight poles and towers of transmission lines use composite insulators. Due to the force, because the lower side ...

Problems solved by technology

[0003] At present, in the construction and maintenance of transmission lines in the power industry, it is very common to install and replace anti-vibration hammers, but now about 95% of the straight poles and towers of transmission lines use composite insulators. Due to the force, because the lower side of the hanging ladder cannot be fixed, the operator has a greater safety risk in the process of going down to the wire. The operator can only use the hanging ladder to go down to the wire, and then follow the wire to the operating point to replace the anti-vibration hammer. The safety risk is high when working, time-consuming and labor-intensive, and very difficult
