Description

Technical Field

[0001] The utility model belongs to the technical field of traveling wheels, in particular to a crane traveling wheel assembly with good stability. Background Art

[0002] Traveling wheels are a type of forgings, mainly used in gantry cranes, port machinery, bridge cranes, mining machinery, etc. The crane moves by cooperating with the traveling wheels and guide rails. The traveling wheels and guide rails are exposed to the outside for a long time, which will cause dust and foreign matter to adhere to the traveling wheels and rails. When the traveling wheels and guide rails are in contact and wear, debris will also be generated. If not processed, the aging and wear of the traveling wheels and guide rails will be aggravated. The Chinese patent document "202222948268.0" is a crane traveling wheel that cleans the debris through the contact surface of the cleaning cotton and the roller, and blows the debris on the guide rails off through the exhaust fan. This structure will cause the debris to adhere to the cleaning cotton, which is not easy to handle later, and may also cause the debris attached to the cleaning cotton to scratch the outer surface of the traveling wheel, and easily form dust through the exhaust fan.
