Rope guiding machine with guide rod type adjustable rope guiding device and clamp type rope pressing device

Abstract

The invention discloses a rope guiding machine with a guide rod type adjustable rope guiding device and a clamp type rope pressing device. The rope guiding machine includes a rope pressing unit, and aguiding rod type thread guiding mechanism. The rope pressing unit is of a clamping type and a rope guiding hole is formed in the rope pressing unit. The rope pressing unit is clamped on the outside diameter of a coiling block in a sleeving mode and can move left and right along an outer thread rope groove of the coiling block. The guiding rod type thread guiding mechanism is connected with the front of a coiling block rope outlet position. The guiding rod type thread guiding mechanism is provided with the adjustable rope guiding device. One end of a thread shaft of the guiding rod type threadguiding mechanism is connected with a small chain wheel. The small chain wheel is connected with a big chain wheel through a chain. The big chain wheel is connected with a joint shaft. The joint shaft is connected with one end of a coiling block shaft of an electric hoist through a screw. A tensioning gear is connected with the chain. A cut-out switch of chain cutting or chain dropping is installed on the tensioning gear.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a rope guide with a guide rod type adjustable rope guide device and a hoop type rope presser. 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 latera...

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
