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

Abstract

This application discloses a rope guide with a pressure wheel type rope pressure device and a guide rod type threaded rope guide device, including a pressure wheel type rope pressure device and a guide rod type thread guide mechanism; the pressure wheel type rope pressure device The fixed seat in the drum is connected to the front of the reel by bolts, and the pressure roller in the pressure roller type rope pressing device is pressed on the steel wire rope of the last circle of the reel; the guide rod type thread guide mechanism is connected to the reel by bolts. The front is directly below the rope pressing device; one end of the threaded shaft on the guide rod type threaded guide mechanism is connected to the pinion; the pinion is meshed with the bull gear; the bull gear is connected to the pinion through a flat key On the joint shaft; the joint shaft is connected to one end of the reel shaft of the electric hoist with screws, and the two are connected by a coaxial line.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a rope guide with a pressure wheel type rope presser and a guide rod type threaded rope guide 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 th...

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
