Speed control-based wire running-preventing protector

Abstract

The invention discloses a speed control-based wire running-preventing protector, which comprises a locking mechanism, a mounting bracket, and guide wheels, wherein the guide wheels are arranged on the mounting bracket through a rotating shaft, and the surfaces of the guide wheels are in contact with a wire; the locking mechanism is arranged on the mounting bracket and comprises a connecting rod a, a connecting rod b, an upper pressure block, a lower pressure block, a guide plate, and a roller; the upper pressure block and the guide plate are fixedly arranged on the mounting bracket, and a guide groove is formed in the guide plate; one end of the lower pressure block is hinged with the connecting rod a, and the other end of the lower pressure block corresponds to the guide groove in the guide plate; one end of the connecting rod a is hinged with the mounting bracket, and the other end of the connecting rod a is hinged with the connecting rod b; the other end of the connecting rod b is connected with the roller, and an reversed L-shaped groove or a 7-shaped groove is formed in the mounting bracket; the roller is arranged in the reversed L-shaped groove or 7-shaped groove, and tension springs are arranged between two ends of the roller and the mounting bracket. The speed control-based wire running-preventing protector provided by the invention is matched with the existing wire griper for use to effectively prevent the wire from running, is convenient to use, and has the advantages of improving the working efficiency and increasing the safety of construction.

Description

technical field [0001] The invention relates to the technical field of power grid engineering construction equipment, in particular to an 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 waste of ...

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.
