Problems solved by technology

[0004] Among the existing tools for replacing linear insulators whose cross-arm tower material is non-water-holding material (angle steel facing downwards), self-developed dual-purpose linear hook clamps are usually used, but such clamps have a process of tightening the screw rod The stress on both sides of the tower will be uneven, and the tower will be deformed, which will greatly increase the risk factor of this work.

Abstract

A vertical double-hanging clamp is characterized by comprising two symmetrically arranged cross arm angle steel clamping apparatuses (2), two sets of lead screws (1) connected with the cross arm angle steel clamping apparatuses (2) respectively, and a balancing pull rod (3) located in the middle of the two cross arm angle steel clamping apparatuses (2) and connected with the two cross arm angle steel clamping apparatuses (2). The beneficial effects of the invention are that: the vertical double-hanging clamp enables the whole work to be operated conveniently, effectively balances the tensile forces generated by tightening the lead screws to thereby not enable the tower materials to deform, enables the personal injury risk during the tightening process to be reduced effectively, does not need the help of other tools when being installed, can be installed rapidly during the installation process, and enables the working risk to be reduced.

Description

technical field [0001] The invention belongs to electric equipment maintenance tools, in particular to the replacement of linear insulator strings and the installation tool structure when the cross-arm angle steel of 110kV and above transmission lines faces downward. Background technique [0002] The insulator is a special insulation control. The insulator plays two basic functions in the overhead transmission line, that is, supporting the wire and preventing the current from returning to the ground. These two functions must be guaranteed. The insulator should not change due to environmental and electrical load conditions. Otherwise, the insulator will not have a significant effect, and it will damage the service life and operating life of the entire line. During the operation of the transmission line, due to external damage, lightning, pollution flashover and other reasons, the insulator self-exploded or lost its insulation function. In order to ensure the safe operation of...
