Electrical power repair tensioning device

Abstract

The invention discloses an electrical power repair tensioning device, and relates to the technical field of tensioning devices. The electrical power repair tensioning device comprises a base, wherein four universal wheels are evenly distributed on the periphery of the lower surface of the base; a bracket A is vertically welded at one side of the upper surface of the base; a bracket B is vertically welded at the other side of the upper surface of the base; through holes are formed in the middle part of the bracket A and the middle part of the bracket B; a rotating shaft A matched with the through hole is arranged between the through hole in the middle part of the bracket A and the through hole in the middle part of the bracket B; and a head pulley is arranged in the middle part of the rotating shaft A. By combination of a sliding chute, the rotating shaft B and a secondary pulley, the rotating shaft B can vertically move in the sliding chute along the direction of the sliding chute; and placement of a cable and pressing of the cable are facilitated. By combination of a pressure rod, a connecting rod and a support rod, synchronous descending of two ends of the rotating shaft B can be ensured by the support rod; the top end of the head pulley is manually attached to the bottom end of the secondary pulley through the pressure rod; and the cable is pressed, so that the stability in the tensioning process is ensured; and the cable is prevented from slipping.

Description

technical field [0001] The invention relates to the technical field of wire tightening devices, in particular to an electric wire tightening device for emergency repair. Background technique [0002] At present, when designing an overhead line, according to the design specifications and standards, it should be divided into tension sections according to the direction of the line and the terrain. Big and small. After the construction and laying out of the new power line is completed, the conductor needs to be tightened on the pole tower. The erection construction tightening tool that existing power overhead line adopts is generally: motorized winch mill or artificial grinding disc. [0003] Motorized winches and artificial grinding discs are very heavy, and power overhead lines often need to be carried out in high mountains. In these places, various power equipment and facilities can only be transported manually. The work is labor-intensive and the risk factor is high. The c...
