Abstract

Embodiments of the invention provide a winch and a lifting device, and relate to the technical field of mechanical equipment. The winch in the embodiments includes a body, a hoisting drum, a rope arranging structure and a transmission structure. The transmission structure is simultaneously in transmission connection to the hoisting drum and the rope arranging structure, so that the rope arrangingstability of the rope arranging structure is ensured through the transmission structure, and the probability of occurrence of the rope biting condition is reduced. Specifically, the transmission structure includes a first gear, a second gear, a third gear, a fourth gear and a fifth gear. When power is transmitted from the hoisting drum to the rope arranging structure through the second gear, the fifth gear and the fourth gear, the fourth gear drives the rope arranging structure to conduct reversed rope arrangement in the axial direction of the hoisting drum. Through the transmission structure,effective reversal of the rope arranging structure is realized, power transmission is realized through gear transmission by means of the transmission structure, high reliability is achieved, the reversing reliability of the rope arranging structure is further improved, the occurrence of rope biting is better reduced, and the service life of steel wire ropes is better prolonged.

Description

technical field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a winch and a lifting device. Background technique

[0002] The wire rope is one of the indispensable key components in the hoisting operation. During the use of the wire rope, the wire rope is often retracted and released by the winch, so that the use of the wire rope is more convenient and quick.

[0003] However, the existing hoist has poor winding stability when the wire rope is collected, that is, when the wire rope on the reel of the hoist is filled with one layer and enters the next layer, it often occurs that the wire rope is not arranged in an orderly manner, but messy winding or Backlog together, there is a phenomenon of biting the rope. In this state, when hoisting for a long time, a certain point of the wire rope is prone to wear and tear, which not only reduces the life of the wire rope, but may lead to safety accidents in severe cases.
