Tackle fixing plate for overhead line stringing

Abstract

The invention discloses a tackle fixing plate for overhead line stringing. The tackle fixing plate comprises a plate-shaped body, a tackle fixing structure and a backup plate. A U-shaped through groove which penetrates through the plate-shaped body in the thickness direction of the plate-shaped body is formed in the plate-shaped body. The plate-shaped body is provided with two first through holes which are formed in the two sides of the U-shaped through groove respectively. Two second through holes are formed in the backup plate. The two second through holes correspond to the two first through holes in position. The backup plate is fixed to the plate-shaped body through two bolts. The tackle fixing structure is arranged at the top end of the plate-shaped body. The tackle fixing structure comprises two vertical plates, wherein the two vertical plates are arranged in parallel, each vertical plate is provided with a third through hole, and a bolt sequentially penetrates through the third through holes of the two vertical plates and is fixed in the two third through holes. The tackle fixing plate for overhead line stringing can improve safety and reliability of electric transmission line conductor stringing, improve stringing efficiency and the like.

Description

technical field [0001] The invention relates to a pulley fixing plate used for wire tightening of overhead lines, in particular to a pulley fixing plate used for wire tightening of overhead line wires in a power system. Background technique [0002] At present, the main method of tightening the wires of transmission lines is to fix the traction rope on the tension clamp. After the wire is tightened, due to gravity, the porcelain bottle is strung under the line, and it needs manpower to twist the porcelain bottle up to the level of the wire and then install it on the cross arm of the pole tower. Guarantee, low line efficiency and high construction cost. [0003] At present, when the wires of the transmission line are tightened, the pulley is usually fixed on the pole tower or concrete pole with No. 8 iron wire or thin steel wire rope. Often, the pulley will jump and fall to the ground under the tension of the tight wire. , causing great safety hazards to tight-line personne...
