Due to the different types of vehicles, rail trains are at the same level as road trains and belong to the same category as trains. In China, rail trains are divided into high-speed EMUs, fast EMUs, and ordinary trains according to their operating speeds, from fast to slow.

[0003] After the rail train is running, its parts need to be cleaned. The current cleaning steps generally include soaking the parts with a cleaning agent at a certain temperature, and then performing ultrasonic cleaning, spraying, rinsing, and drying on the parts.

[0004] When spraying parts, manual spraying is adopted, which increases the workload of the staff. Summary of the invention

[0005] In view of this, the present invention provides a rail vehicle parts spraying device to solve the problem in the prior art that when spraying vehicle parts, a manual method is used to spray, which increases the work intensity of the staff.

[0006] The technical solution adopted by the present invention is as follows:

Several vertical pipes are arranged at equal intervals along the hypotenuse of the lower mounting box, and the top of the vertical pipe is connected to the upper rotating piece, and the lower mounting box is connected to the external water tank. The cleaning liquid in the water tank is pressurized. The pump provides pressure; in this solution, when it is necessary to spray the parts, the parts are placed in the mesh basket, and then the mesh basket is placed on the support plate, the motor and the pressure pump are started, and the pressure pump pressurizes the cleaning liquid in the water tank and sprays it from the first nozzle to the parts in the mesh basket to remove the dirt on the parts. Secondly, while spraying, the motor drives the support plate to rotate, so that the mesh basket on the support plate rotates, and then the cleaning liquid sprayed by the first nozzle can spray various positions of the parts; In summary, in the present invention, by setting the vertical pipe, the first nozzle, the motor and the pressure pump, the cleaning liquid in the water tank is pressurized and sprayed from the first nozzle to the parts in the mesh basket to remove the dirt on the parts. And the support plate can spray various positions of the parts, replacing the manual spraying method and reducing the labor intensity of the staff; on the other hand, the present invention arranges the spray assembly at the corner of the spray box, which can increase the space utilization rate of the spray box and reduce the volume of the spray box compared to installing it at other positions. The specific principle is: since the support plate is rotating, the area covered by the support plate when it rotates one circle is a circle, and the spray box is a rectangular parallelepiped structure. Therefore, there will be a part of the space at the corner of the spray box that will not be covered by the rotation of the support plate, so Therefore, the present invention arranges the spray assembly at the corner, which can make use of this part of the space and improve space utilization. If the spray assembly is arranged on the side wall of the spray box, the length or width of the spray box must be increased to prevent the spray assembly from interfering with the support plate.

The pressure sensor sends a sensing signal to the cylinder, and the cylinder drives the sealing door to move, thereby sealing the spray box.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
