End part anti-loosening self-locking rope sleeve for electric hoist steel wire rope

Abstract

The invention relates to an end part anti-loosening self-locking rope sleeve for an electric hoist steel wire rope. The end part anti-loosening self-locking rope sleeve comprises a spiral coil and a lock disk which are fixed together through a screw rod, wherein the spiral coil is provided with a rope groove which extends spirally; the spiral clockwise directions of the inner ring of the rope groove and the outer ring of the rope groove are opposite; an arc-shaped bent part is arranged on a joint between the inner ring and the outer ring; a groove surrounding the spiral coil is formed in the circumferential end face of the outer side of the spiral coil; the steel wire rope can be coiled in the rope groove in a shape matching way, and finally enters the groove to be wound; the steel wire rope in the rope groove can be compressed by the lock disk. The inner ring and the outer ring of the rope groove are arranged in opposite clockwise directions, and the twisting force of the steel wire rope on the spiral coil just forms tightening force for screwing the steel wire rope of the inner ring towards the circle center, thereby forming a self-locking structure, so that loosening of the steel wire rope caused by frequent change of the pulling force is effectively avoided; through the lock disk, the steel wire rope is further prevented from being loosened from the spiral coil.

Description

technical field [0001] The invention relates to a rope reel for an electric hoist, in particular to an anti-loosening self-locking rope sleeve at the end of an electric hoist wire rope. Background technique [0002] The electric hoist connects the reel and the hook through a wire rope. The items mounted on the hook need to be transported on the I-beam by the electric hoist. The wire rope actually carries all the weight of the item. The two free ends of the steel wire need to be prevented from slipping. For fixing the structure, there are still certain risks in the existing fixing method of wedges and hoops. The steel wire rope is usually changed between the two states of continuous tension and relaxation, which is prone to stress fatigue and loosening. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art and provides a self-locking rope sleeve for preventing loosening at the end of the wire rope of an electric hoist.
