[0033] Reference Figure 1 and Figure 2As shown, a fully automatic high-pressure jet cleaning machine comprises: a frame 1, a cleaning chamber 2 is arranged inside the frame 1, a cleaning part placement net 3 is arranged in the cleaning chamber 2, the cleaning part placement net 3 is a mesh structure, and is used to place the parts that need to be cleaned of the EMU, and an upper movable plate 4 and a lower movable plate 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 in the frame 1, and the upper movable plate 4 and the lower movable plate 5 are connected to the cleaning part placement net 3 through a connecting rod mechanism 31, thereby ensuring that the upper movable plate 4 and the lower movable plate 5 can approach or move away from the cleaning part placement net 3 at the same time.

[0034] Reference Figure 6 and Figure 7 As shown, a sewage trough 10 and a clean water trough 6 are provided at the bottom of the frame 1, a sewage filter 11 is provided between the sewage trough 10 and the clean water trough 6, the cleaning chamber 2 is connected to the sewage trough 10, a heating rod 62 is provided in the clean water trough 6, the heating rod 62 heats the water body to achieve the purpose of rapid cleaning, and the heating temperature is most suitable for 25°C-80°C. In order to achieve a better cleaning effect, cleaning liquid can also be added to the clean water trough 6.

[0035] Reference Figure 3 and Figure 4 As shown, pipelines 9 are slidably mounted on the upper movable plate 4 and the lower movable plate 5 , respectively. A plurality of cleaning nozzles 91 are arranged on the pipelines 9 , and the clean water tank 6 is connected to the pipelines 9 through a high-pressure pump 61 .

[0036] Reference Figure 5 As shown, the cleaning machine also includes a lifting mechanism 7, including a first motor 71. The first motor 71 drives the upper movable plate 4 and the lower movable plate 5 to move closer to or away from the cleaning piece placement net 3 through the first transmission mechanism 72, thereby controlling the pressure sprayed onto the surface of the cleaning piece. 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 connected to the screw 721 is fixedly connected to the upper movable plate 4. When the first motor 71 is started, the screw 721 will be driven to rotate, thereby driving the nut 722 connected to the upper movable 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 a bevel gear.

[0037] Reference Figure 3The cleaning machine also includes a translation mechanism 8, including a second motor 81. The second motor 81 drives the pipe 9 to slide horizontally on the upper movable plate 4 and the lower movable plate 5 through the second transmission mechanism. In order to enable the pipe 9 to slide, a slide groove 92 is provided on the upper movable plate 4 and the lower movable plate 5, and the pipe 9 is installed in the slide groove 92. In addition, the pipe 9 on the lower movable plate 5 is provided with a slide bar 51, and the pipe 9 on the upper movable plate 4 is provided with a slider 93. The slider 93 is connected to the slider 93, so that the upper movable plate 4 and the lower movable plate 5 can slide simultaneously. The second transmission mechanism is a connecting rod mechanism, and the connecting rod mechanism is hinged with the slider 93. When the second motor 81 rotates, the slider 93 and the slider 51 are driven by the connecting rod mechanism to enable the pipe 9 to slide on the slide groove 92 of the upper movable plate 4 and the lower movable plate 5.

[0038] In order to achieve the spraying of the cleaning nozzle 91 without dead angles on the cleaning surface, the cleaning nozzle 91 of the upper movable plate 4 and the cleaning nozzle 91 of the lower movable plate 5 are staggered.

[0039] The cleaning machine is provided with a drain valve 101 in the sewage tank 10 and a water inlet valve 63 in the clean 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 is provided on the frame 1 to close the cleaning chamber 2, so as to prevent the splashing of sewage during the cleaning process.

[0040] The working principle of the present invention is: when in use, the cleaning parts are placed on the cleaning parts placement net 3. Since different cleaning parts have different spray pressure requirements or different sizes of cleaning parts during cleaning, the present invention drives the upper movable plate 4 and the lower movable plate 5 to approach or move away from the cleaning parts placement net 3 through the lifting mechanism 7, the first motor 71 and the first transmission mechanism 72, thereby controlling the pressure sprayed onto the surface of the cleaning parts. In addition, since the cleaning parts placement net 3 is fixedly installed in the frame 1, the upper movable plate 4 and the lower movable plate 5 are connected to the cleaning parts placement net 3 through the connecting rod mechanism 31. Since the size of the connecting rod mechanism 31 is the same, the distances of the upper movable plate 4 and the lower movable plate 5 moving relative to the cleaning parts placement net 3 are also the same.

[0041] In addition, since a translation mechanism 8 is provided, the second motor 81 drives the pipe 9 to slide horizontally on the upper movable plate 4 and the lower movable plate 5 through the second transmission mechanism, thereby realizing the synchronous forward and backward movement of the upper movable plate 4 and the lower movable plate 5, and since the cleaning nozzles 91 between adjacent pipes 9 are staggered, the cleaning nozzles 91 can be sprayed on the cleaning surface without dead angles.

[0042] In order to prevent a large amount of water and cleaning liquid from being wasted during cleaning, which increases environmental pollution and waste of resources, the cleaning chamber 2 is connected to the sewage tank 10. The sewage in the sewage tank 10 is filtered through the sewage filter 11 and flows into the clean water tank 6, and then flows into the pipeline 9 through the high-pressure pump 61, thereby realizing the reuse of water resources.

[0043] The present invention can also control the motor, high-pressure pump and heater through PLC, realize accurate control of the temperature of the cleaning liquid, and show automation, improve the cleaning efficiency and cleaning quality, reduce the manpower input during cleaning, and reduce the cost during cleaning.

[0044] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
