The yaw direction of the brushing mechanism on the base is the same as the driving direction of the multiple unit train, and there is an included angle of 15° - 30° between the car washing mechanism and the side facade of the multiple unit train. This results in that the multiple unit train must drive into the car wash from a specified direction. The driving direction of the multiple unit train determines the way of entering and leaving the car wash for washing and the number of shunting operations. Therefore, the efficiency of this car washing method is low.

[0027] The working limit unit 12 includes a first strip plate 14, a second strip plate 15 and a telescopic cylinder 13. The first strip plate 14 is perpendicularly and fixedly connected to the second strip plate 15, and both the first strip plate 14 and the second strip plate 15 are parallel to the railway track.
[0028] Two first connecting ears 16 and two limit posts 18 are respectively fixedly connected to the two surfaces of the first strip plate 14. The first connecting ear 16 is hinged to the column 6. The two limit posts 18 are respectively arranged at both ends of the first strip plate 14. A limit bolt 10 is installed on the limit post 18, and the axis of the limit bolt 10 is perpendicular to the axis of the limit post 18.
[0029] A second connecting ear 17 is fixedly connected to the second strip plate 15. Both ends of the telescopic cylinder 13 are respectively hinged to the column 6 and the second connecting ear 17.
[0030] In this embodiment, by reasonably configuring the bristle size of the brush set 5, multiple unit trains of different models can be cleaned, thereby increasing the compatibility and versatility of the present utility model.
[0031] Specific embodiment two: Combining Figure 1 and Figure 3 To describe this embodiment, a solenoid valve is installed on the swing cylinder 11 in this embodiment. The swing cylinder 11 is pneumatically connected to the valve port of the solenoid valve through a pipeline, and the swing cylinder 11 is controlled by the solenoid valve.
[0032] Other compositions and connection relationships are the same as those in specific embodiment one.
[0033] Specific embodiment three: Combining Figure 1 To describe this embodiment, this embodiment further includes a stop limit switch 8. The stop limit switch 8 is installed on the column 6. The brush set frame 2 can abut against the contact of the stop limit switch 8. The stop limit switch 8 is electrically connected to the solenoid valve on the swing cylinder 11. Other compositions and connection relationships are the same as those in specific embodiment one or two.
[0034] Embodiment 4: Combined with Figure 1 This embodiment will be described. This embodiment further includes a pneumatic spring 1, and both ends of the pneumatic spring 1 are hinged to the brush set frame 2 and the column 6 respectively. The other components and connection relationships are the same as those in Embodiment 1, 2 or 3.
[0035] Working principle
[0036] Combined with Figures 1 to 6 The working principle of the present utility model will be described:
[0037] As Figure 6 shown, the way of driving the EMU into the car wash from left to right for car washing is defined as car washing in the A direction; conversely, the way of driving the EMU into the car wash from right to left for car washing is defined as car washing in the B direction.
[0038] When the EMU is washed in the A direction, the swing cylinder 11 drives the brush set frame 2, so that the yaw direction of the brush set frame 2 is the same as the driving direction of the EMU. At this time, the piston rod of the telescopic cylinder 13 retracts, and the limit post 18 is perpendicular to the horizontal plane. When the brush set frame 2 abuts against the limit bolt 10 in the A direction, the swing cylinder 11 stops swinging, the reduction motor 7 drives the brush set 5 to rotate, and the spray pipe 4 sprays water on the brush set 5 to start car washing.
[0039] After the car washing is completed, the piston rod of the telescopic cylinder 13 extends, and both the first connecting ear 16 and the second connecting ear 17 rotate around their hinge points, thereby driving the first strip plate 14 and the second strip plate 15 to rotate, so that the limit bolt 10 no longer abuts against the brush set frame 2. Subsequently, the swing cylinder 11 continues to swing. When the brush set frame 2 abuts against the contact of the stop limit switch 8, the swing cylinder 11 stops swinging. At this time, the brush set frame 2 is parallel to the railway track, and the pneumatic spring 1 prevents the brush set frame 2 from swinging, playing a role of safety protection.
[0040] When the EMU is washed in the B direction, the movement modes of each component are the same as those in the process of car washing in the A direction, and will not be elaborated here.
[0041] The present utility model has been disclosed in the above preferred embodiments. However, it is not intended to limit the present utility model. Any person skilled in the relevant art, without departing from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
