Technical Field
[0001] The utility model relates to the technical field of electric power construction tools, in particular to a wire tightener. Background Art
[0002] The wire tensioner, also called ratchet tensioner, is used to tighten the wire during the construction of overhead line installation. When using it, first loosen the wire rope or galvanized iron wire on the wire tensioner and fix it on the cross arm, clamp the wire with a wire clamp, and then pull the special wrench. Due to the anti-reversal effect of the ratchet, the wire rope or galvanized iron wire is gradually wound around the ratchet drum to tighten the wire and fix the tightened wire on the insulator.
[0003] Traditional tensioners use binding ropes or clamps to tighten the wires, and use pull ropes to cross the crossarms. The upper and lower personnel cooperate to tighten the transmission wires. This method is time-consuming and labor-intensive, with low installation efficiency, many people to cooperate, and high labor intensity. In particular, the construction workers are far away and communication is difficult. Once the cooperation is not good, it will bring great threats to the safety of the tower climbers and even cause serious accidents. Therefore, it is urgent to design a tensioner to solve the above problems. Utility Model Content
