Hoisting mechanism automatic rope-arranging device

Abstract

The invention relates to a hoisting mechanism automatic rope-arranging device. The hoisting mechanism automatic rope-arranging device comprises two supporting hinge seats. A spindle is arranged between the two supporting hinge seats, a rolling drum is arranged at the spindle, the rolling drum is wound with a steel wire rope, the tail end of the steel wire rope at the rolling drum is arranged in arope groove in the outer circumferential surface of a rope guiding wheel, and the rope guiding wheel is rotatably arranged on a guiding seat; the guiding seat is in threaded connection with a threadedrod A, a limiting rod is parallelly arranged above the threaded rod A, the two ends of each of the limiting rod and the threaded rod A are connected to a sliding block A and a sliding block B correspondingly, and the sliding block A and the sliding block B are slidably arranged in horizontal sliding grooves in a supporting frame A and a supporting frame B correspondingly; and the sliding block Aand the sliding block B are in threaded connection with a threaded rod B, a motor A and a motor B are connected with the outer ends of the threaded rod A and the threaded rod B correspondingly, and travel switches are arranged at the two ends of the lifting rod correspondingly. In general, the hoisting mechanism automatic rope-arranging device has the advantages that the structural design is reasonable, the steel wire rope can be effectively prevented from twisting together, and radial force borne by a guiding device is small.

Description

technical field [0001] The invention belongs to the technical field of hoisting, and in particular relates to a rope arranging device, in particular to an automatic rope arranging device for a hoisting mechanism. Background technique [0002] Due to the long length of the steel wire rope on the crane drum, the steel wire rope needs to be coiled in multiple layers on the drum. Due to the mutual friction and extrusion force of the steel wire ropes, it is easy to appear disordered ropes, rope bites, and rope squeezes, resulting in wire rope damage. The service life is shortened, which affects the working efficiency of the lifting equipment. In addition, when the crane lifts heavy objects, there will be a phenomenon of oblique pull, which will easily cause the wire rope to wrap around one end of the drum, and even the wire rope will run out of the drum and cause safety accidents. In order to prevent Accidents occur when the wire rope is messed up on the surface of the drum. It i...

[0002] Due to the long length of the steel wire rope on the crane drum, the steel wire rope needs to be coiled in multiple layers on the drum. Due to the mutual friction and extrusion force of the steel wire ropes, it is easy to appear disordered ropes, rope bites, and rope squeezes, resulting in wire rope damage. The service life is shortened, which affects the working efficiency of the lifting equipment. In addition, when the crane lifts heavy objects, there will be a phenomenon of oblique pull, which will easily cause the wire rope to wrap around one end of the drum, and even the wire rope will run out of the drum and cause safety accidents. In order to prevent Accidents occur when the wire rope is messed up on the surface of the drum. It is usually necessary to install a rope guide device on the drum to arrange the wire rope when the drum retracts and unwinds the rope. The structure of the existing rope arrangement device is relatively complicated, and many rope guide devices The rope guide wheel needs to bear the radial force exerted on the rope guide wheel by the heavy object suspended at the end of the wire rope during the rope arranging process. Usually, the weight of the heavy object suspended at the end of the steel wire rope is relatively heavy, so it is necessary to push the guide rope on the rope guide device. The mechanical properties of the screw rod moved by the pulley are relatively high; therefore, it is very necessary to provide an automatic rope discharge device for the hoisting mechanism with a reasonable structural design, which can effectively prevent the kinking of the wire rope, and the radial force on the guide device is small.
