Description

Technical Field

[0001] The present invention relates to the technical field of wire rope lubrication, and particularly to a wire rope lubrication assembly for a crane. Background Art

[0002] A crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range. Most existing cranes use wire ropes in combination with pulley blocks and hooks to lift heavy objects. The wire rope is a structure made by stranding multiple groups of fine steel wires. There are relatively large gaps between multiple groups of fine steel wires, which will result in a large contact area between the wire rope and the air, thus leading to the problem of easy rust. The existing solution is to infiltrate grease for rust prevention and lubrication into the wire rope to achieve the protection of the wire rope, thereby achieving the effects of extending the service life of the wire rope and improving its working smoothness.

[0003] In the prior art, there is a wire rope lubrication device for a crane with an application publication number of CN217736885U, which includes a support rod. A positioning ring is fixedly arranged on one side of the support rod. The top of the positioning ring is fixedly provided with a PLC control device electrically connected to a pressure sensor. An oil pump lubrication assembly is arranged above the oil lubrication cover. A second wire guide wheel is fixedly arranged at the bottom of the positioning ring. One end of the wire rope sequentially winds around the first wire guide wheel and the second wire guide wheel and extends downward. The oil pump lubrication assembly is started to inject lubricating oil into the oil lubrication cover. As the lubricating oil in the oil lubrication cover increases, the pressing plate compresses the compression spring downward. When the pressing plate touches the pressure sensor, the oil pump lubrication assembly stops injecting oil, so as to achieve the purpose of quantitative lubrication.

[0004] However, the lubricating oil mechanism of the wire rope lubrication device for a crane it provides has a low degree of fit with the wire rope, and the lubricating oil is not evenly applied. Therefore, it is necessary to provide a wire rope lubrication assembly for a crane to solve the above technical problems. Summary of the Invention
