Electric power tightener

Abstract

The invention relates to the technical field of electric power maintenance auxiliary equipment, and discloses an electric power tightener which comprises a lifting hook, wherein a bearing ring is fixedly installed on the inner wall of the bottom of the lifting hook, a rotating buckle is fixedly installed at the bottom end of the bearing ring, a fixing rod is movably connected to the inner wall ofthe rotating buckle, a steel wire rope is movably connected to the surface of the fixing rod, and the bottom end of the rotating buckle is fixedly and movably connected with a movable wheel. Accordingto the electric power tightener, when a steel wire rope is loosened, a movable block is located above a first gear ring, an electric telescopic rod extends at the same time to enable a fixed block tobe located on the inner wall of a fixed hole, then a rocker is manually rotated, the rocker moves to drive a movable ring to move on the inner wall of a protective shell, the movable ring is fixed toa mounting block through a magnetic ring and an elastic piece in the moving process, the fixed block rotates to drive the first gear ring to rotate, the first gear ring rotates to drive a fixed gearring to rotate, and the fixed gear ring rotates to enable a hoisting gear to rotate to contract the steel wire rope.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance auxiliary equipment, in particular to an electric wire tensioner. [0002] technical background [0003] Wire tensioner, also called ratchet tensioner, is used for tensioning wires in the construction of overhead line laying. When using it, first loosen the steel wire rope or galvanized iron wire on the wire tensioner and fix it on the cross arm. The wire clamp clamps the wire, and then pulls the special wrench. Due to the anti-reversal effect of the ratchet, the steel wire rope or galvanized iron wire is gradually wound on the ratchet drum to tighten the wire, and the tightened wire is fixed on the insulator, and then first Release the ratchet to loosen the steel wire rope or galvanized iron wire, then loosen the wire clamp, and finally wind the steel wire rope or galvanized iron wire on the drum of the ratchet. [0004] However, the general electric wire tensioner often has th...

Problems solved by technology

[0005] 1. During the construction process, due to the influence of the environment and geographical location, the cable tensioner is often used for operations in places with small spaces. Usually, the cable tensioner uses a wrench to tighten the cable, and the wrench is too short to tighten the force. If the wrench is too long, due to the narrow space, it will collide with other parts and cause damage to the parts, which is very inconvenient and has troubled countless construction workers;

[0006] 2. The fixing strength of the general wire tensioner cannot be adjusted, and the cable needs to be tightened with the same force all the time, which is easy to cause fatigue, and the force exerted by the personnel after tightening cannot further accurately take up the wire tensioner Fixed work, waste of manpower and there is a certain risk of loose thread
