Rope guide provided with rope pressing device

Abstract

This application discloses a rope guide with a rope pressing device, which includes a pressure wheel type rope pressing device and a thread guide mechanism; the pressure wheel type rope pressing device is connected to the thread guide mechanism through a pin shaft, and the The above pressure wheel type rope pressing device is connected with the thread guide mechanism through a spring, so that the pressure wheel presses on the steel wire rope of the last turn on the reel; the two ends of the thread guide mechanism are respectively connected to the rope outlet of the reel by bolts The front of the threaded shaft; one end of the threaded shaft on the thread 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 one end of the reel shaft of the electric hoist; the small A safety cover is installed outside the 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 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
