Problems solved by technology

This utility model can support the drooping cables, but the utility model uses the fastening rope to bind the drooping cables on the branches of trees. Although it can solve the problem of cable drooping to a certain extent, the practical The new model requires trees to provide fixation, and it is difficult for the utility model to function in places without trees

Abstract

The invention relates to a temporary support device for high-voltage cables, which includes a base and an anchoring mechanism. A left ear plate seat and a right ear plate seat are respectively arranged on the left and right sides of the upper part of the base, and an inverted U-shaped connection is arranged on the left ear plate seat and the right ear plate seat. Seat, the connecting seat is provided with a support rod body, the upper end of the support rod body is provided with a clamping mechanism, a pair of pull rings are symmetrically arranged on the front and rear sides of the support rod body, a pull rope for pulling up and fixing the support rod body is arranged on the pull ring, and a fixed rod body is set on the base. Pile, base, anchor mechanism, left lug seat, right lug seat, connection seat, support rod body and pull ring are all made of aluminum alloy, and the aluminum alloy is made of the following mass percentage: Mg: 2.0-3.2% ; Si: 3.5~4.5%; Mn: 0.2~0.3%; Cr: 0.1~0.2%; Zr: 0.18~0.25%; Ti: 0.35~0.40%; Yb: 0.15~0.3%; 0.05% impurities; the invention not only has high strength, good corrosion resistance and light weight, but also has compact structure, stable support and does not need to rely on nearby trees as a foundation.

Description

technical field [0001] The invention belongs to the technical field of electric power auxiliary tools, and in particular relates to a temporary support device for high-voltage cables. Background technique [0002] Usually, outdoor high-voltage cables are laid through electric poles. When there are trees between two adjacent electric poles, as the trees grow, the branches are easy to press against the cables, and the long-term pressure will gradually elongate the cables. In order to ensure the safety of power supply, workers will cut off the branches that interfere with the wires, but the stretched cables cannot be restored, causing the cables between the two utility poles to droop in an arc shape. In case of strong winds, the cables will sway from side to side. It poses a hidden danger to the safety of power supply. At the same time, because the work of tightening the cable is more complicated and requires the participation of many people, the workers who cut the branches g...
