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

Abstract

The invention discloses a rope guide with a rope pressing device and a threaded guide mechanism. The rope guide comprises the rope pressing device and the threaded guide mechanism, wherein the rope pressing device is connected onto the threaded guide mechanism through a pin roll; the rope pressing device is connected with the threaded guide mechanism through a spring, so that a pressure wheel is pressed on the last ring of a steel wire rope on a winding drum; the threaded guide mechanism is equipped with an adjustable rope guide device; the threaded guide mechanism is connected to the front ofa rope outlet of the winding drum; one end of a threaded shaft on the threaded guide mechanism is connected with a pinion; the pinion is in engaged connection with a big gear; the big gear is connected to one end of a winding drum shaft of an electric hoist; a safety cover is mounted at the pinion and the large gear; and the safety cover is connected to a housing on the end head 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 and a threaded guiding 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, 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 with...
