Description

Technical Field

[0001] This utility model relates to the field of rail transit vehicle cleaning, specifically to a non-contact high-pressure contour cleaning mechanism for the end of a train. Background Technology

[0002] Currently, the train end-of-train cleaning mechanism is a contact brush cleaning system. The horizontal brush group contacts the train end, and through a combination of lifting and traveling movements, the horizontal brush group's trajectory matches the contour of the train end. A current sensor monitors the contact pressure between the brush bristles and the train body during brush rotation to achieve optimal cleaning results. However, because it's a contact cleaning method, improper control of the relative position between the brush mechanism and the train when entering and leaving the cleaning area can cause the bristles to snag on protrusions, leading to equipment damage. Furthermore, such accidental pulling can cause structural deformation, posing a safety hazard. Additionally, contact brush cleaning is a point-by-point, surface-by-surface cleaning method. The bristles can only remove stains through repeated friction with the train surface, resulting in a long cleaning time and relatively low cleaning efficiency.

[0003] In summary, how to propose a non-contact high-pressure contour cleaning mechanism to address the aforementioned technical problems has become a pressing issue for those skilled in the art. Utility Model Content
