A fixture for installing color signs of transmission lines

Abstract

A fixture for installing color signs of transmission lines, which mainly includes a cross-shaped plane clamp body fixed on the cross-arm tower material of transmission lines and capable of clamping color signs. The two transverse ends of the clamp body are respectively provided with a forward It is bent to clamp the hook of the color label; the back of the clamp body is equipped with bolts and nuts to clamp the fixed clamp block on the cross-arm tower material; the cross-shaped plane clamp body is connected by two strip plates. wherein the two ends of the horizontal strip-shaped board are respectively provided with clip hooks; the lower end of the vertical strip-shaped board is also provided with clip hooks, forming a clamping structure of three-sided clamping color signs; the vertical The upper and lower ends of the strip plate are respectively provided with bolt holes, in which at least one first group of bolts and nuts that can fix the clamping block for clamping the cross-arm tower material on the clamp body are arranged; and the first The set of bolts and nuts passes through the color label, and the color label is fastened on the clip body with the first set of bolts and nuts.

Description

technical field [0001] The invention relates to a fixture for installing color signs of power transmission lines, and belongs to the technical field of power line safety technology engineering. Background technique [0002] In order to prevent mistaken registration of electric lines in multi-circuit lines or electrodes in DC lines on the same tower, it is required that each base tower should be provided with identification marks (ie color codes, identification marks, etc.) and dual names. Because the transmission line is exposed in the wild and exposed to wind and rain for a long time, it is easy to cause mechanical fatigue of the bolts fixing the color plate, causing the color plate to break off or the bolt hole of the color plate to be rusted and broken, so that the color plate falls from a high place, causing personnel Injury or property loss; How to improve the firmness of the color label fixing and reduce damage has become a topic that is often discussed. [0003] The ...

AI Technical Summary

Problems solved by technology

[0004] One is that the long-term mechanical fatigue at the bolt position of the fixed color plate is caused by the vibration of the wind, causing the color plate to break off or the bolt hole of the color plate to be corroded and broken, and the defect rate is high;

[0005] The second is that the color sign falls from a high place, which may hurt the safety of pedestrians below;

[0006] The third is that there is no line color label at the crossarm of the power line, which may cause the possibility of mistakenly boarding the line
