Abstract

The invention discloses a screw-type adjusting plate for an electric power line, belongs to the technical field of electric power line connection fittings, and aims at solving the technical problems that a wire length adjusting device for the electric power line is low in labor intensity and can carry out live-working. According to the technical scheme, the screw-type adjusting plate for the electric power line comprises an adjusting plate body, a screw body and a slide block body, wherein an adjusting plate connecting hole is formed in one side of the adjusting plate body; a through hole which is narrow in two ends and wide in middle is formed in the middle of the adjusting plate body; a slide chute is formed in the middle of the through hole; a guide rail is arranged at one side of the slide chute; the screw body is arranged in the through hole in the middle of the adjusting plate body; the slide block body is arranged in the through hole in the middle of the adjusting plate body; a through threaded hole is formed in the slide block body; the slide block body is in threaded connection with the screw body through the through threaded hole; one end of the slide block body and the slide chute are in clearance fit; a guide rail stop bench at the other end and the guide rail are in sliding connection; and a slide block connection hole is formed in one side of the slide block body. The screw-type adjusting plate for the electric power line is applied to an adjustment of wire sag of the electric power line.

Description

technical field [0001] A power line spiral adjustment plate belongs to the technical field of power line connection fittings. Background technique [0002] The inclination of the power line tower caused by the mining affected area and (area with poor geology) will cause excessive tension of the ground wire of the tension tower. It is necessary to release the tension of the ground wire in time (adjust the length of the ground wire) to ensure the safe operation of the line , if the release is not timely, it may cause accidents such as tower collapse and disconnection, so the adjustment workload is heavy and frequent. [0003] When the line runs for a long time, the twisting, whipping, and sag increase of the phase-split conductors caused by the long-term operation of the line will affect the safe operation of the line, and the length of the wire must be adjusted in time to restore the best operating state of the line. [0004] At present, the DB type adjustment plate is used ...
