Hoist guide rope device with guide rod type thread guide mechanism

Abstract

The invention discloses a hoist guide rope device with a guide rod type thread guide mechanism. The device comprises the guide rod type thread guide mechanism which is connected to the front face of awinding drum through a bolt, a rope pressing wheel in the guide rod type thread guide mechanism is pressed on a steel wire rope on the last ring of the winding drum, the steel wire rope drops down through a guide rope wheel and is connected to a lifting hook set, one end of a thread shaft on the guide rod type thread guide mechanism is connected with a small chain wheel, the small chain wheel isconnected with a large chain wheel through a chain, the large chain wheel is connected to one end of a winding drum shaft of an electric hoist, a tensioning device is connected to the chain, and a chain breaking or falling circuit breaking switch is arranged on the tensioning device.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a hoist rope guide with a guide rod type thread guide mechanism. Background technique [0002] The rope guide is an important part of the electric hoist. Its function is to ensure that the wire ropes can be neatly arranged on the reel to prevent the wire ropes from being chaotic, overlapping, etc., which will cause mechanical failure of the electric hoist; most of the existing electric hoists use the clamp type rope guide. The inner ring of this kind of rope guide is set on the threaded rope groove outside the reel, and the rope guide is provided with a guide hole, and the wire rope is discharged from it; when the reel rotates, the threaded rope groove drives the rope guide along the drum shaft To move the steel wire rope along the threaded rope groove of the drum neatly; however, the structure of this traditional rope guide is fragile, and the lateral force it can withstand duri...

Problems solved by technology

The inner ring of this kind of rope guide is set on the threaded rope groove outside the reel, and the rope guide is provided with a guide hole, and the wire rope is discharged from it; when the reel rotates, the threaded rope groove drives the rope guide along the drum shaft To move the steel wire rope along the threaded rope groove of the drum neatly; however, the structure of this traditional rope guide is fragile, and the lateral force it can withstand during work is small; in actual work, the steel wire rope cannot be suspended vertically. It often happens that
