Rope guide with clamp type rope-pressing device and guide rod type thread guiding mechanism

Abstract

The present application discloses a rope guide with a hoop type rope pressing device and a guide rod type thread guiding mechanism, including a rope pressing device and a guide rod type thread guiding mechanism; the rope pressing device is of the hoop type, and the The rope-pressing device is provided with a guide rope port, and the rope-pressing device is connected to the reel and can move left and right along the external thread rope groove of the reel; the guide rod-type thread guide mechanism is connected to the electric The front of the gourd rope outlet; one end of the threaded shaft on the guide rod type threaded guide mechanism is connected to the small sprocket; the small sprocket is connected to the large sprocket through a chain; the large sprocket is connected to the coil of the electric hoist One end of the cylinder shaft; a safety cover is installed outside the small sprocket and the large sprocket, and the safety cover is connected to the shell at the 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 hoop-type rope pressing device and 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 late...

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
