[0022] Refer toFigure 1 and Figure 2 As shown in Figure 2 , a fully automatic high-pressure jet cleaning machine includes: a frame 1, a cleaning chamber 2 is arranged inside the frame 1, a cleaning part placement net 3 is arranged inside the cleaning chamber 2, the cleaning part placement net 3 is a mesh structure, mainly used for placing parts of the EMU that need to be cleaned. Upper and lower moving plates 4 and 5 are respectively arranged on the upper and lower sides of the cleaning part placement net 3; the cleaning part placement net 3 is fixedly installed inside the frame 1, and the upper moving plate 4 and the lower moving plate 5 are connected to the cleaning part placement net 3 through a connecting rod mechanism 31, so as to ensure that the upper moving plate 4 and the lower moving plate 5 can approach or move away from the cleaning part placement net 3 simultaneously.

[0023] Refer to Figure 6 and Figure 7 As shown in Figure 7 , a sewage tank 10 and a clean water tank 6 are arranged at the bottom of the frame 1, a sewage filter 11 is arranged between the sewage tank 10 and the clean water tank 6, the cleaning chamber 2 is communicated with the sewage tank 10, a heating rod 62 is arranged inside the clean water tank 6, and the heating rod 62 heats the water body to achieve the purpose of rapid cleaning. The most suitable heating temperature is 25°C - 80°C. In order to achieve a better cleaning effect, cleaning liquid can also be added to the clean water tank 6.

[0024] Refer to Figure 3 and Figure 4 As shown in Figure 4 , pipes 9 are respectively slidably installed on the upper moving plate 4 and the lower moving plate 5, a number of cleaning nozzles 91 are arranged on the pipes 9, and the clean water tank 6 is communicated with the pipes 9 through a high-pressure pump 61.

[0025] Refer to Figure 5 As shown in Figure 5 , this cleaning machine further includes a lifting mechanism 7, including a first motor 71. The first motor 71 drives the upper moving plate 4 and the lower moving plate 5 to approach or move away from the cleaning part placement net 3 simultaneously through a first transmission mechanism 72, thereby controlling the pressure sprayed on the surface of the cleaning parts. The first transmission mechanism 72 is a screw and nut structure. The first motor 71 is connected to the screw 721, and the nut 722 sleeved on the screw 721 is fixedly connected to the upper moving plate 4. When the first motor 71 is started, it will drive the screw 721 to rotate, thereby driving the nut 722 connected to the upper moving plate 4 to move up and down. Since the first motor 71 is installed on the top of the frame 1, in order to facilitate the connection of the screw 721 and realize the change of the transmission direction, the first motor 71 can drive the screw 721 to rotate through bevel gears.

[0026] Refer to Figure 3, the cleaning machine further includes a translation mechanism 8, which includes a second motor 81. The second motor 81 drives the pipe 9 to slide horizontally on the upper moving plate 4 and the lower moving plate 5 through a second transmission mechanism 82. In order to enable the pipe 9 to slide, chutes 92 are provided on the upper moving plate 4 and the lower moving plate 5, and the pipe 9 is installed in the chutes 92. In addition, a sliding rod 51 is provided on the pipe 9 on the lower moving plate 5, and a sliding block 93 is provided on the pipe 9 on the upper moving plate 4. The sliding block 93 is inserted through the sliding rod 51, so as to realize the simultaneous sliding of the upper moving plate 4 and the lower moving plate 5. The second transmission mechanism 82 is a connecting rod mechanism, and the connecting rod mechanism is hinged to the sliding block 93. When the second motor 81 rotates, the pipe 9 is driven to slide on the chutes 92 of the upper moving plate 4 and the lower moving plate 5 through the connecting rod mechanism, driving the sliding block 93 and the sliding rod 51.

[0027] In order to achieve non-blind-zone spraying of the cleaning nozzle 91 on the cleaning surface, the cleaning nozzles 91 on the upper moving plate 4 and the cleaning nozzles 91 on the lower moving plate 5 are arranged in a staggered manner.

[0028] A drain valve 101 is provided in the sewage tank 10 of the cleaning machine, and a water inlet valve 63 is provided in the water tank 6, so as to facilitate the discharge of sewage and the inflow of clean water. At the same time, a door body 12 for closing the cleaning chamber 2 is provided on the frame 1, so as to prevent the splashing of sewage during the cleaning process.

[0029] The working principle of the present invention is as follows: When in use, the cleaning parts are placed on the cleaning part placement net 3. Since different cleaning parts have different spraying pressure requirements or different sizes during cleaning, the present invention controls the pressure sprayed on the surface of the cleaning parts by the lifting mechanism 7. The first motor 71 drives the upper moving plate 4 and the lower moving plate 5 to approach or move away from the cleaning part placement net 3 simultaneously through the first transmission mechanism 72. In addition, since the cleaning part placement net 3 is fixedly installed in the frame 1, the upper moving plate 4 and the lower moving plate 5 are connected to the cleaning part placement net 3 through a connecting rod mechanism 31. Since the sizes of the connecting rod mechanisms 31 are the same, the distances that the upper moving plate 4 and the lower moving plate 5 move relative to the cleaning part placement net 3 are also the same.

[0030] In addition, due to the provision of the translation mechanism 8, the second motor 81 drives the pipe 9 to slide horizontally on the upper moving plate 4 and the lower moving plate 5 through the second transmission mechanism 82, thereby realizing the synchronous forward and backward movement of the upper moving plate 4 and the lower moving plate 5. And since the cleaning nozzles 91 between adjacent pipes 9 are arranged in a staggered manner, non-blind-zone spraying of the cleaning nozzles 91 on the cleaning surface can be achieved.

[0031] In order to prevent a large amount of water and cleaning liquid from being wasted during cleaning, increasing environmental pollution and waste of resources, the cleaning chamber 2 is communicated with the sewage tank 10. The sewage in the sewage tank 10 is filtered by the sewage filter 11 and then flows into the water tank 6, and is pumped into the pipe 9 through the high-pressure pump 61, so as to realize the reuse of water resources.

[0032] The present invention can also control the motor, high-pressure pump and heater through a PLC, achieving precise control of the cleaning liquid temperature, demonstrating automation, improving the cleaning efficiency and quality, reducing the labor input during cleaning, and lowering the cleaning cost.

[0033] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge scope of those of ordinary skill in the art to which the present invention pertains.
