[0002] An EMU bogie is a "small vehicle" composed of two wheel sets, a frame and some devices, and is about the same size as an ordinary car. The EMU vehicle is mounted on the bogie, and the bogie can rotate to a certain extent. The bogie mainly has functions such as load bearing, guiding, vibration damping, traction, and braking.

[0003] The EMU bogie needs to be maintained regularly, and during the maintenance process, the bogie needs to be cleaned so that technicians can clearly see and understand the structure of the bogie and successfully complete the inspection and maintenance. The existing cleaning equipment is composed of structures such as water pipes, nozzles, and steering rods. When cleaning, technicians rinse the bogie according to the parts that need to be inspected and maintained. The existing cleaning equipment also has the following defects: there is a large amount of dust on the bogie before rinsing. If rinsed directly, a large amount of dust will flow down with the water, forming material marks locally, and it needs to be rinsed twice to be cleaned; and after cleaning, the water quality needs to be wiped dry, and it is difficult to wipe dry the inside of some structural gaps. Therefore, this application proposes a cleaning equipment for EMU bogies. Utility Model Content

[0034] Embodiment

[0035] As Figures 1-4 As shown, a cleaning device for a train bogie proposed in the present application includes an air cylinder 1 and a handle 6 connected to its end. The other end of the air cylinder 1 is provided with a flushing assembly 2 for flushing and cleaning the bogie. The flushing assembly 2 includes a water tray 21 embedded at the end of the air cylinder 1. The outer end of the water tray 21 is connected with a nozzle 22. The nozzle 22 is a high-pressure nozzle, which has a certain water pressure during flushing and can improve the flushing effect. The bottom end of the air cylinder 1 is fixedly connected with a water supply pipe 23 communicated with the water tray 21. The input end of the water supply pipe 23 is communicated with an external water supply device through a hose to supply water to the nozzle 22 by the external water supply device. It further includes a dust blowing assembly 4 arranged at the end of the air cylinder 1 and outside the flushing assembly 2 for blowing dry dust on the bogie before flushing. The dust blowing assembly 4 includes a plurality of second air nozzles 41 connected to the end of the air cylinder 1. The plurality of second air nozzles 41 are annularly distributed at the end of the air cylinder 1. A second air pressure balance pipe 42 is connected to the side wall of the air cylinder 1 near the flushing assembly 2. A first one-way valve is arranged on the second air pressure balance pipe 42. External gas can enter the air cylinder 1 through the second air pressure balance pipe 42, but the gas in the air cylinder 1 will not be discharged outward through the second air pressure balance pipe 42.

[0036] Furthermore, a drying assembly 3 is arranged outside the end of the air cylinder 1 for blowing away water quality after flushing. The drying assembly 3 includes a gas collecting hood 31 sleeved at the end of the air cylinder 1. One end of the gas collecting hood 31 close to the flushing assembly 2 is connected with a plurality of first air nozzles 32 distributed annularly. The air cylinder 1 is communicated with the gas collecting hood 31 through a plurality of air pipes 33 between the end close to the handle 6 and the gas collecting hood 31. A first air pressure balance pipe 34 is connected to the side wall of the gas collecting hood 31. A second one-way valve is arranged on the first air pressure balance pipe 34. The gas inside the gas collecting hood 31 will not be discharged outward through the first air pressure balance pipe 34. Under the action of negative pressure, external gas can enter the gas collecting hood 31. The output ends of the plurality of first air nozzles 32 all incline towards the axis of the air cylinder 1, so that the wind output by the plurality of first air nozzles 32 is concentrated in one direction, and the water droplets after flushing can be blown away smoothly.

[0037] In this embodiment, an air supply component 5 for intermittently driving a soot blowing component 4 and a drying component 3 is arranged inside the air cylinder 1.

[0038] Specifically, the air supply component 5 includes a motor 51 embedded at the end of the handle 6. The output end of the motor 51 penetrates through the end of the air cylinder 1 and is fixedly connected to a lead screw 52. A piston plate 53 is sleeved on the side wall of the lead screw 52 in a transmission manner. The outer side wall of the piston plate 53 is in sliding contact with the inner wall of the air cylinder 1. By moving the piston plate 53 in different directions, wind power is provided for the soot blowing component 4 and the drying component 3 respectively. A guide rod 54 is fixedly connected to the inner wall of one side of the air cylinder 1. The piston plate 53 slidably penetrates through the guide rod 54 to guide the piston plate 53 so that the piston plate 53 can slide in the air cylinder 1 under the rotation of the lead screw 52. It should be noted that when the piston plate 53 moves towards the flushing component 2, external gas will enter the air collecting hood 31, the air delivery pipe 33, and the air cylinder 1 through the first air pressure balance pipe 34, enabling the piston plate 53 to smoothly move towards the soot blowing component 4, and discharging the gas inside the air cylinder 1 through a plurality of second air nozzles 41 to complete the dust blowing action. When the piston plate 53 moves towards the handle 6, external gas will enter the air cylinder 1 through the second air pressure balance pipe 42 to balance the air pressure inside the air cylinder 1. At this time, the movement of the piston plate 53 will squeeze the gas inside the air cylinder 1 into the air collecting hood 31 through a plurality of air delivery pipes 33 and blow it out through a plurality of first air nozzles 32 to blow away the water droplets flushed on the bogie.

[0039] The working principle of this embodiment is as follows: When cleaning the bogie, hold the handle 6, align the flushing component 2 with the part of the bogie that needs to be cleaned, first start the motor 51. The output shaft of the motor 51 rotates to drive the lead screw 52 to rotate, and the lead screw 52 rotates to drive the piston plate 53 to move towards the flushing component 2 (under the guiding action of the guide rod 54), and spray the gas inside the air cylinder 1 out through a plurality of second air nozzles 41 to blow away the dust on the bogie of the EMU (when the piston plate 53 moves to the end of the air cylinder 1 close to the flushing component 2, the motor 51 pauses). Then start the external water supply device to supply water into the water supply pipe 23. The water enters the water tray 21 through the water supply pipe 23 and then sprays water on the bogie through the spray head 22 for flushing. With the cooperation of the soot blowing component 4, the flushing and cleaning effect can be improved. After the flushing is completed, start the motor 51 again to make the piston plate 53 move towards the handle 6, squeeze the gas inside the air cylinder 1 into the air collecting hood 31 through a plurality of air delivery pipes 33, and finally blow it out through a plurality of first air nozzles 32 to blow away the water droplets on the bogie, thereby enabling the flushed bogie to dry quickly and improving the cleaning efficiency.

[0040] The above specific embodiments are only the preferred embodiments of the present application. Based on the technical solution of the present application and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments; the above specific embodiments are only explanations of the present application and do not limit the present application.
