Special two-way pulley for line corner tight line operation

Abstract

The invention discloses a bidirectional pulley specially used for line corner wire tightening work. The bidirectional pulley comprises a pulley. The pulley is connected with a pulley shaft through a bearing; the pulley shaft is relatively fixed to a fixation clamp plate through a hydraulic cylinder; the fixation clamp plate is fixed on a cross arm through a fixation mechanism; the fixation mechanism comprises a U-shaped clamp and a J-shaped bolt, wherein the U-shaped clamp is moveably connected to one end of the fixation clamp plate, and the J-shaped bolt passes through a fixation hole in the U-shaped clamp; and the fixation clamp plate is provided with an L-shaped clamp groove. According to the bidirectional pulley, the groove in the pulley is utilized to limit the wires and cooperate with a wire tightening tool to tighten the wires, thereby allowing wire sag adjustment to be very easy, saving both time and labor, but also not causing wire abrasion; the hydraulic cylinder is utilized to allow the wires to separate away from the pulley for binding; and the L-shaped clamp groove of the fixation clamp plate is clamped on a fixation rod of an insulator, and meanwhile, the J-shaped bolt and the U-shaped clamp are utilized to enable the fixation clamp plate to be fixed to the cross arm, so that installation and fixation are done easily, easy disassembly is achieved after construction is finished, and construction efficiency is greatly improved.

Description

technical field [0001] The invention relates to an electric power construction tool, in particular to a special two-way pulley for line corner tightening operations. Background technique [0002] In the construction process of low-voltage lines, small corners are often encountered. In this case, it is very difficult to tighten the wires. Even if two people drag on the wire poles, it is difficult to make the four wires reach the same sag. , the wires placed on the cross arm are easily worn and "injured" during the wire bonding (tightening) process, which affects the performance of the wires. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a special two-way pulley for line corner line tightening operation that is easy to tighten, saves time and effort, and does not wear the wire. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:...

[0002]During the construction of low-voltage lines, small corners are often encountered. In this case, it is very difficult to tighten the lines, even if two people struggle on the lines It is also difficult to make the four wires reach the same sag when dragged by the ground. The wires on the cross arm are easy to wear and "injure" during the wiring (tightening) process, which affects the performance of the wires.
