Speed control-based bidirectional running-prevention line protector

Abstract

The invention discloses a speed control-based bidirectional running-prevention line protector. The speed control-based bidirectional running-prevention line protector comprises locking mechanisms and an installation rack, wherein the locking mechanisms are arranged on the installation rack, the two locking mechanisms are symmetrically arranged along a vertical central surface of the installation rack, each locking mechanism comprises a connection rod a, a connection rod b, an upper press block, a lower press block, a guide plate and a rolling shaft, one end of the lower press block is hinged with the connection rod a, the other end of the lower press block is corresponding to a guide groove formed in the guide plate, one end of the connection rod a is hinged with the installation rack, the other end of the connection rod a is hinged with the connection rod b, the other end of the connection rod b is connected with the rolling shaft, a left half n-shaped or right half n-shaped groove is formed in the installation rack, the rolling shaft is arranged in the left half n-shaped or right half n-shaped groove, tension springs are arranged between two ends of the rolling shaft and the installation rack and are arranged above the rolling shaft, and the directions of the tension springs point to a horizontal groove tail end of the left half n-shaped or right half n-shaped groove from the rolling shaft. The speed control-based bidirectional running-prevention line protector is used with an existing wire clamp in a matching way, a wire can be effectively prevented from run, and the construction safety is improved.

Description

technical field [0001] The invention relates to the technical field of power grid engineering construction equipment, in particular to a two-way anti-running line protector based on speed control. Background technique [0002] In the construction process of transmission lines, when tightening the wires, it is necessary to clamp the wires with a wire clamp first, and then use the wire tensioner to tighten the wires. However, the existing wire clamps often encounter wires being stuck in the process of use. The phenomenon of slipping in the device and the wire falling out of the clamping device, once the wire runs during the line construction, the surface of the wire will be worn out, and corona will easily be generated in the process of transmitting electric energy in the future, resulting in waste of electric energy and noise, etc. harm. On the other hand, to continue the construction after running the line, it is necessary to re-draw the conductor, which greatly causes a wa...

AI Technical Summary

Problems solved by technology

[0003] 1. The wire is over-tracted during the wire tightening process, causing the wire rope of the wire tensioner to break and run away;

[0004] 2. The wire does not match the clamping part of the wire clamp, and the wire slips or runs away;

[0005] 3. The staff did not completely clamp the wire into the clamping part of the clamping device, and the wire running phenomenon occurred;

[0006] 4. The quality of the insulating layer of the insulated wire is poor, and the inner insulating layer of the clamping part of the clamping device is broken and then runs away.

[0007] In actual construction, simple manual pulling of the wires or fixing the ends of the wires on poles and cross-pieces are usually used as anti-running measures for the wires, which is laborious and laborious, reduces work efficiency, and the effect is not good, and the safety performance is poor.
