An electric wire tightener

Abstract

The invention relates to the technical field of electric power maintenance auxiliary equipment, and discloses an electric wire tensioner, which includes a hook, a load-bearing ring is fixedly installed on the bottom inner wall of the hook, and a rotating buckle is fixedly installed on the bottom end of the load-bearing ring. The inner wall of the rotary buckle is movably connected with a fixed rod, the surface of the fixed rod is movably connected with a steel wire rope, and the bottom end of the rotary buckle is fixedly and movably connected with a movable wheel, which is an electric wire tightener. When the steel wire rope is relatively loose, At this time, the movable block is located above the first ring gear, and at the same time, the electric telescopic rod is extended so that the fixed block is located on the inner wall of the fixed hole, and then the rocker is manually rotated, and the movement of the rocker drives the movable ring to move on the inner wall of the protective shell. During the movement, the movable ring The magnetic ring and shrapnel are fixed with the mounting block, the rotation of the fixed block drives the first gear ring to rotate, the rotation of the first gear ring drives the rotation of the fixed gear ring, and the rotation of the fixed gear ring makes the hoisting gear rotate to shrink the 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
