Wire tightening device for power line construction

Abstract

The invention discloses a wire tightening device for power line construction. The device comprises a first fixing block and a second fixing block, which are opposite to each other. A first screw is rotatably connected between the first fixing block and the second fixing block. A servo motor is fixedly arranged on the second fixing block. One end of the servo motor penetrates the second fixing block and is fixedly connected with the first screw. The first screw is in screw-connection with a slider. The slider is connected with the first fixing block and the second fixing block through a guide mechanism. Both ends of the slider are fixedly connected with connection blocks. A mounting cavity is arranged in each connection block. Wire holes are arranged in the side walls of two ends of each mounting cavity. According to the invention, the structure is compact; a wire which needs to be tightened can be buckled and fixed repeatedly; the wire is effectively prevented from detaching and fluttering; the problem that a traditional tightening device causes fatigue and affects work efficiency when used for tightening by a human is solved; and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of electric power construction, in particular to a wire tightening device for power line construction. Background technique [0002] In the process of electric power construction, a locking device is usually used to tighten the wires erected in the air. Traditionally, a wire tensioner is usually used to tighten the wires. The wire tensioner, also called a ratchet tightener, is a It is used for tensioning wires in line laying construction. When in use, first loosen the steel wire rope or galvanized iron wire on the wire tensioner, and fix it on the cross arm, clamp the wire with the wire clamp, and then pull the special wrench. [0003] When using the wire tensioner to tighten the wires, the process of clamping the wires with the clamps is prone to detachment between the wires and the clamps, and the detached wires will swing, which is easy to accidentally injure others. The wire puller needs to manually pu...

Problems solved by technology

[0003] When using the wire tensioner to tighten the wires, the process of clamping the wires with the clamps is prone to detachment between the wires and the clamps, and the detached wires will swing, which is easy to accidentally injure others. The wire puller needs to manually pull the special wrench manually. Since most of the workers work in the space, it is inconvenient to replace the person who tightens the wire, which will easily cause construction fatigue and affect work efficiency.
