Description

Technical Field

[0001] This utility model relates to the technical field of high-speed train equipment, specifically a high-speed train bogie cleaning device. Background Technology

[0002] Bogies are an important component of rail transit vehicles and require regular cleaning. Bogie cleaning equipment is an important piece of equipment in the maintenance of rail transit vehicles, used to efficiently and automatically clean oil, dust and other impurities from the surface of the bogies, ensuring the cleanliness of the bogies.

[0003] In existing technologies, high-pressure water jet cleaning technology is usually required when cleaning bogies. High-pressure water pumps (pressure is usually 10-50MPa) generate high-speed water flow to impact the dirt on the surface of the bogie. This technology has the advantages of removing stubborn oil stains and rust layers, and is equipped with a water circulation filtration system to reduce wastewater discharge. It is often combined with robotic arms or rotating nozzles to achieve multi-angle cleaning.

[0004] High-pressure washing alone cannot effectively clean mud or stubborn stains on the bogie, thus affecting the bogie's related functions. Utility Model Content

[0066] The operating principle of a bogie cleaning device for high-speed trains is as follows: the operator first drives the contact part 112 to contact the inner wall of the track, and then the entire device is driven to move along the track by the traveling component.

[0067] When cleaning the bogie, the operator first sprays the cleaning agent in the reservoir 211 onto the surface of the bogie through the first nozzle 213. Then, the cleaning disc 232 is driven to abut against the side wall of the bogie. The first gear 226 drives the second gear 227 to rotate, which in turn drives the cleaning disc 232 to rotate. At the same time, the electric push rod 235 drives the striking block 236 to clean the dirt on the surface of the bogie. Then, the cleaning brush 233 cleans the stains.

[0068] Finally, the high-pressure water jet is sprayed onto the surface of the bogie through the second nozzle 243 to complete the cleaning operation.
