Abstract

The invention discloses a connecting and rotating assembly. The connecting and rotating assembly comprises a first sub-connecting and rotating assembly and a second sub-connecting and rotating assembly, wherein the first sub-connecting and rotating assembly comprises a base and a connecting and rotating piece, and the connecting and rotating piece is rotatably connected around a first axis relative to the base; the second sub-connecting and rotating assembly comprises a connecting support and a second connecting plate, and one end of the connecting support is fixedly connected with a second connecting plate. The connecting and rotating assembly can be applied to the power transmission tower, and is beneficial to releasing the tension of a cross arm and optimizing the stress conditions of the cross arm and a tower body.

Description

technical field [0001] The present application relates to the technical field of power transmission, in particular to a connection between a rotating assembly and a power transmission tower. Background technique [0002] Transmission lines are an important lifeline for the development of the national economy. Once a transmission line in a certain area fails, it will cause immeasurable economic losses to the regional users it serves. Therefore, ensuring the normal operation of transmission lines is extremely important for daily life and economic development. Important, and the transmission tower is a necessary condition to ensure the normal operation of the transmission line. [0003] Most of the current transmission towers include a tower body and a cross arm for hanging transmission lines, wherein the cross arm is arranged on the tower body and extends outward for a certain length. The inventors of the present application have found that currently, under extreme weather su...
