Background Art

[0002] The wheel of a railway freight car is one of the important parts of the vehicle. The quality of wheel maintenance is directly related to the safety and reliability of train operation. During the wheel maintenance process, it is necessary to copy the wheel manufacturing year and month, manufacturing unit code, wheel model and other marking information; the marking information of the rolled steel wheel is all on the inner end face of the hub. After the wheel leaves the factory, the inner end face of the hub is always exposed to the outside, and a lot of dust, rust and other foreign matter will adhere to its surface. During maintenance, the marking on the inner side of the hub can no longer be seen clearly. At this time, it is necessary to clean the inner side of the hub, but in the prior art, the cleaning work of the inner side of the hub is manually cleaned, and the wheel needs to be pushed to rotate during the cleaning process to clean all areas inside the wheel hub as much as possible. This operation method not only has high labor intensity for workers, but also requires workers to stand on the inner side of the production line during the operation, which has great safety hazards and a high risk factor; this operation method is inefficient and cannot be applied to automated wheel axle production lines. Therefore, it is urgent to develop a wheel hub inner side cleaning device for an axle production line to realize automated cleaning of the inner side of the hub. Summary of the invention
