Rope guide device with adjustable rope guide device and pressing wheel type rope pressing device

Abstract

The invention discloses a rope guide device with an adjustable rope guide device and a pressing wheel type rope pressing device. The rope guide device comprises the rope pressing device and a thread guide mechanism; the rope pressing device is connected to the thread guide mechanism through a pin shaft, the rope pressing device is connected with the thread guide mechanism through a spring, a pressing wheel is pressed on a steel wire rope on the last circle of a winding drum, the thread guide mechanism is provided with an adjustable rope guide device, the thread guide mechanism is connected tothe front face of the rope outlet position of the winding drum, a small chain wheel is connected to one end of a thread shaft of the thread guide mechanism, and is connected with a large chain wheel through a chain, the large chain wheel is connected to a joint shaft, the joint shaft is connected to one end of a winding cylinder shaft of an electric hoist through a screw, a tensioning device is connected to the chain, and a chain breaking or falling circuit breaking switch is arranged on the tensioning device.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a rope guide with an adjustable rope guide device and a pressure wheel 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 lateral fo...

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
