Rope guide with hoop-type rope pressing device and guiding-rod type adjustable rope guiding mechanism

Abstract

The present application discloses a rope guide with a hoop type rope pressing device and a guide rod type adjustable rope guiding mechanism, including a rope pressing device and a guide rod type thread guiding mechanism; the rope pressing device is a hoop type, The rope-pressing device is provided with a guide rope opening, and the rope-pressing device is hooped on the outer diameter of the reel, and can move left and right along the outer thread rope groove of the reel; the guide rod type thread guiding mechanism is connected to the reel The front of the barrel where the rope comes out; the guide rod type thread guide mechanism has an adjustable guide rope device; one end of the thread shaft on the guide rod type thread guide mechanism is connected to the pinion; the pinion gear is meshed with the large gear; the large gear It is connected to one end of the reel shaft of the electric hoist; a safety cover is installed outside the pinion and the bull gear, and the safety cover is connected to the shell at the end of the electric hoist.

Description

technical field [0001] The application relates to the field of cranes, in particular to a rope guide with a clamp type rope pressing device and a guide rod type adjustable rope 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 and overlapping, which may cause mechanical failure of the electric hoist; most of the existing electric hoists use clamp type. rope guide. The inner loop of the rope guide is sleeved on the threaded rope groove outside the reel, and the rope guide is provided with a rope guide port, from which the wire rope is discharged; when the reel rotates, the rope guide is driven by the threaded rope groove along the reel shaft. The wire rope can be moved along the threaded rope groove of the drum in a neat manner; however, the structure of this traditional rope guide is fragile, an...

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
