Overhead transmission line multiple buffering device

Abstract

The invention discloses an overhead transmission line multiple buffering device. The device comprises a vertical plate, a transverse plate arranged at the upper end of the vertical plate, perpendicular to the vertical plate and having the left end surface fixedly connected with the upper end of the vertical plate, a windage yaw-proof assembly used for fixing a power transmission line, a telescopic assembly comprising two fixed plates symmetrically arranged on the side surfaces of the vertical plate, a supporting plate rotationally connected with the vertical plate through a hinge rod, a hydraulic rod, a placement plate rotationally connected to the lower part of the front end of the hydraulic rod, a rectangular frame, at least two U-shaped supports, a second spring and a cover plate, wherein a rectangular groove is concavely formed in the lower surface of the placement plate; a rectangular block protrudes outwards in the center of the rectangular groove; the power transmission line penetrates into the U-shaped supports; and the U-shaped supports are used for bearing the weight of the power transmission line. The problems that the breakage situation is easily caused during cold and hot alternation if the power transmission line between two telegraph poles is excessively horizontal and the breakage also can be caused if wind is excessively high during wind blowing are solved.

Description

technical field [0001] The invention relates to the field of overhead transmission lines, in particular to a multiple buffer device for overhead transmission lines. Background technique [0002] During the laying process of the overhead transmission line, there will be a certain margin between the two poles, and the transmission line will not be horizontal. If it is too horizontal, it is prone to breakage when the cold and heat alternate. When it is windy, If the wind is too strong, breakage will also occur. If the power line margin between the two poles is too long, it will cause the power line to swing back and forth when the wind blows. Wear and tear, electric leakage and other hazards occur. Contents of the invention [0003] The purpose of the present invention is to provide a multiple buffer device for overhead transmission lines to solve the problem that during the laying process of overhead transmission lines proposed in the above background technology, if the tra...
