After a period of use, rail trains need to be cleaned. Existing cleaning machines are often located in a relatively fixed position and distributed on both sides of the track. When the train passes, the train is cleaned. This kind of train cleaning method makes the car washing machine often only able to clean the train in a specific position and direction, with a narrow cleaning range and a relatively fixed cleaning direction. When it is necessary to clean a special position of the train, the car washing machine needs to be rotated. However, the structure of the existing car washing machine is relatively complex.

[0044] The working principle of the utility model is as follows: the roller 45 in the clutch assembly 4 is pressed by the spring 43 into the V-groove support 13 in the bottom plate assembly 1. By turning the clamping bolt 48 on the clutch assembly 4, the clamping force of the spring 43 can be adjusted to meet the needs of different working conditions. When an external force acts on the upper plate assembly 2 of the safety clutch device, the external force refers to the force provided by the pneumatic assembly 9. If the external force is less than the force set by the train car washing machine safety clutch device, the train car washing machine safety clutch device will not operate. If the external force is greater than the force set by the train car washing machine safety clutch device, the roller 45 in the clutch assembly 4 is subjected to the force provided by the pneumatic assembly 9 and rolls out of the V-groove support 13, and then enters the adjacent 90-degree V-groove support 13, thereby realizing the avoidance function and playing a safety protection role.
