Problems solved by technology

[0003] The current power cross-arms of high-voltage overhead lines are often assembled and spliced ​​by a single steel structure truss. After assembly and splicing, the power cross-arms of high-voltage overhead lines are mostly fixed structures, and it is difficult to adjust the distance between insulators according to the actual wiring harness specifications. The distance between them keeps a certain safe distance, and the power cross-arm is often operated at high altitude when

Abstract

The invention provides a high-voltage overhead line power cross arm which comprises a mounting frame, an insulator, a shifting sliding groove, a clamping rotating shaft, a clamping rotating rod, a clamping sliding block, a clamping spring, a shifting mechanism, a positioning mechanism, a supporting seat and a supporting spring. The problems that an existing high-voltage overhead line power cross arm is usually formed by assembling and splicing a single steel structure truss, the spacing distance between insulators is difficult to adjust according to the specification of an actually-installed wire harness to keep a certain safe distance, the power cross arm is always in high-altitude operation during installation and fixation, the number of supporting frames needing to be assembled and fixed is large, the work intensity and work amount of installation work of workers are increased, insulators on the electric power cross arm are generally fixedly installed, special disassembly tools are needed when the insulators are damaged and need to be replaced, the manual work amount is large, and the work efficiency of insulator disassembly and installation work is difficult to improve are solved.

Description

technical field [0001] The invention relates to the technical field of electric power cross-arms, in particular to a power cross-arm for high-voltage overhead lines. Background technique [0002] The power cross arm is an important part of the pole tower. The power cross arm is an angle iron fixed horizontally on the top of the utility pole. There is a porcelain bottle on it, which is used to install insulators and fittings to support the wires and lightning conductors and keep them in accordance with regulations. A certain safe distance. [0003] The current power cross-arms of high-voltage overhead lines are often assembled and spliced ​​by a single steel structure truss. After assembly and splicing, the power cross-arms of high-voltage overhead lines are mostly fixed structures, and it is difficult to adjust the distance between insulators according to the actual wiring harness specifications. The distance between them keeps a certain safe distance, and the power cross-a...
