Problems solved by technology

[0003] Generally, transmission lines are exposed to the natural environment, affected by breeze vibration, ice-covered dancing, etc., the line drives the suspension clamp to vibrate at high frequency. In the long run, the locking pin at the connection between the suspension clamp's rotary shaft and the hanger is easily damaged, broken or As a result, the suspension clamp and the hanger fall off, causing great trouble to the safe and stable operation of the line. Among the annual professional defects in power transmission, the proportion of defects caused by the lack of suspension clamp locking pins is second only to bird nests and trees. defects, but the governance effect is the most difficult

Abstract

The invention discloses a hanging wire clamp for preventing hanging boards from falling off, comprising: a wire clamp main body, including an upper part of a hanger, a middle part of the hanger protruding downward from the upper part of the hanger, and a lower part of the hanger arranged at the lower end of the middle part of the hanger, The middle part of the hanger protrudes outward, and a gap is formed between the middle parts of the two hangers, and the lower parts of the two hangers are connected by bolts; The placement slot and the clamping plate arranged on the lower end of the hull; and the fast clamping line assembly, the fast clamping line assembly is arranged between the hull and the clamping plate.

Description

technical field [0001] The invention relates to the technical field of stand growth models, in particular to a suspension wire clamp for preventing hanging boards from falling off. Background technique [0002] The suspension clamp is used to fix the wire on the insulator string of the straight pole tower, hang the lightning protection wire on the straight pole tower, and can also be used to support the transposition wire on the transposition tower and fix the jumper and suspension wire of the tension-resistant corner tower The usual stereotyped products of clips now retain the U-shaped bolt style (usually called ship-shaped cable clip), which is composed of U-shaped bolts on the hanger, a clip hull made of malleable cast iron, and a pressure plate. It can be used, it can bear the installation load of the wires in the vertical span, and it does not allow the clamp to slide or break away from the insulator string when the line is running normally or the line is broken.
