Rope guide provided with rope pressing device

Abstract

The invention discloses a rope guide provided with a rope pressing device. The rope guide comprises a pressing wheel type rope pressing device and a threaded guide mechanism; the pressing wheel type rope pressing device is connected to the threaded guide mechanism through a pin shaft; the pressing wheel type rope pressing device is connected with the threaded guide mechanism through a spring so that a pressing wheel is pressed on the last circle of a steel rope on a winding drum; the two ends of the threaded guide mechanism are each connected to the front of a rope discharging position of thewinding drum through a bolt; one end of a threaded shaft on the threaded guide mechanism is connected with a small chain wheel; the small chain wheel is connected with a large chain wheel through a chain; the large chain wheel is connected to one end of a drum shaft of an electric hoist; and a safety shield is installed outside the small chain wheel and the large chain wheel and is connected to ashell of an end of the electric hoist.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a rope guide with a rope pressing device. 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 during work is small; in ac...

AI Technical Summary

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 objects are pulled obliquely and dragged obliquely, so that it is easy to break the clamp type rope guide or other guide wheel type rope guides or pull them away from the threaded rope groove on the drum. Once such an accident occurs, When the ground operators found the problem, the wire ropes on the reel were seriously confused, overlapped, and blocked, and the electric hoist had broken down and could not be used; therefore, the traditional rope guide used by the existing electric hoist had obvious problems The defect is one of the main factors of mechanical failure
