Self-adaptive positioning device for crane

Abstract

The invention discloses a self-adaptive positioning device for a crane, and relates to the technical field of crane equipment. The crane comprises a crane body, a lifting appliance device is slidably mounted at the top of the crane body, a positioning device is arranged at the bottom of the lifting appliance device and comprises a U-shaped groove frame, the U-shaped groove frame is fixed to the bottom of the lifting appliance device, and arc groove sliding plates are slidably mounted on the left side and the right side of the bottom of the inner wall of the U-shaped groove frame correspondingly; the opposite sides of the arc groove sliding plates on the left side and the right side are elastically connected with the inner wall of the U-shaped groove frame through elastic plates, and protruding columns are fixed to the bottoms of the elastic plates. The arc chute sliding plate is matched with the elastic plate, so that the arc chute sliding plate buffers the steel wire rope of the lifting appliance device through the elastic plate, the problems that the steel wire rope shakes to be separated from the center of the fixing frame and is abraded are solved, and the service life of the steel wire rope of the lifting appliance device is prolonged.

Description

technical field [0001] The invention relates to the technical field of crane equipment, in particular to an adaptive positioning device for a crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. The working characteristics of lifting equipment are intermittent movements, that is, the corresponding mechanisms for taking materials, moving, and unloading in a working cycle are alternately working. The development and use of cranes in the market are becoming more and more extensive. [0003] Most of the existing cranes use steel wire ropes for hoisting. The general steel wire rope will swing when lifting the goods, so that the steel wire rope will deviate and break away from the central axis of the spreader, so that the steel wire rope cannot be kept at the center of the crane spreader. During the swing process, there will be friction between the pulleys in the...

Problems solved by technology

[0003] Most of the existing cranes use steel wire ropes for hoisting. The general steel wire rope will swing when lifting the goods, so that the steel wire rope will deviate and break away from the central axis of the spreader, so that the steel wire rope cannot be kept at the center of the crane spreader. During the swing process, there will be friction between the pulleys in the spreader, which will accelerate the wear of the wire rope and reduce the service life of the wire rope. At the same time, the swing of the wire rope during the lifting process is also dangerous. Therefore, we propose a An Adaptive Positioning Device for Cranes
