[0002] With the increasing number of railway vehicles year by year, the cleaning of the outer skin has also become an important part of railway maintenance, which is of great significance for ensuring the beauty, safety of the train and extending the service life of the vehicle.

[0003] At present, the cleaning of the outer skin of railway vehicles mainly relies on manual labor, and there are many problems: 1) Manual cleaning is limited by human physical strength and efficiency. Usually, it takes a lot of time. Each group of workers can clean about 5-10 trains per day, and multiple repeated operations are required, resulting in low production efficiency; 2) The quality of manual cleaning is affected by various factors such as the skills, experience, work attitude and environmental conditions of workers. There are differences in the cleaning effects of different workers, and the physical strength and state of workers will also affect the cleaning quality, so the operation quality is unstable; 3) During the manual cleaning process, workers need to climb to the top of the train for cleaning, which is prone to safety accidents such as falling, so there are potential safety hazards for workers; 4) The cost of manual maintenance is high.
