[0002] Wire tightener is divided into hand pull (hand) hoist, ratchet wire tightener, double hook wire tightener, is used in overhead line laying construction as the tensioning wire. When using, first loosen the steel wire rope or galvanized iron wire on the wire tightener, and fix on the cross arm, clamp the wire with the wire clamp, then pull the special wrench. Due to the anti-reverse effect of the pawl, gradually wind the steel wire rope or galvanized iron wire on the ratchet drum, and make the wire tight. Fix the tight wire on the insulator. Then loosen the pawl, loosen the steel wire rope or galvanized iron wire, and finally wind the steel wire rope or galvanized iron wire on the ratchet drum.

[0003] The anti-slip ability of the mainstream wire tightener on the market at present depends on the experience of the operator seriously, and the wedge-shaped clamp block only relies on friction to fix the wire. Experimental data shows that when there is oil stain, frost or oxide layer on the surface of the wire, the clamping force will decay by more than 60%, resulting in sudden slipping accident. The ratchet drum type locking of the existing wire tightener may cause the wire to loosen due to loosening and slipping, which affects the normal tightness adjustment of the wire, and the locking ability is relatively not good, forcing the operator to stop frequently and tighten, which affects the construction efficiency and hides the safety hazard.
