[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Railway vehicle body cleaning machines are specialized equipment used to clean dirt from the surface of railway vehicles. They typically use water, cleaning agents, and cleaning brushes to automatically clean the exterior surfaces, doors, and windows of various types of rail transit vehicles.

[0027] Due to the inherent technical drawbacks of existing technologies, such as large size and inconvenience in use, please refer to... Figures 1-7This embodiment provides a cleaning mechanism for a railway vehicle body cleaning machine. The cleaning structure is divided into two parts: an upper shell 2 and a lower shell 3. By folding the upper shell 2, the overall space occupied by the cleaning mechanism is reduced. The mechanism includes a cleaning machine 1 with wheels at the bottom. The lower shell 3 is installed on the side wall of the cleaning machine 1. The top of the lower shell 3 is hinged to the upper shell 2 via a hinge shaft. The two sides of the upper shell 2 are respectively provided with a flipping mechanism 4 installed on the top of the cleaning machine 1. Both the upper shell 2 and the lower shell 3 are equipped with a double-row brush disc mechanism 5. A wiper mechanism 6 is hinged between the double-row brush disc mechanisms 5 and installed inside the upper shell 2 and the lower shell 3. In use, the cleaning machine 1 is pushed to one side of the vehicle and brought close to the outer wall of the vehicle. The brush disc mechanism 5 and the wiper mechanism 6 are brought into contact with the outer wall of the vehicle. The entire machine is then moved to begin the cleaning operation.

[0028] Currently, the mechanical structures of the cleaning machines 1 on the exterior walls of high-speed trains in my country are too large, causing inconvenience when moving or passing through doors due to their size. To address this issue, the flipping mechanism 4 includes a motor 401 mounted on the top of the cleaning machine 1. A drive gear 402 is fixed on the output shaft of the motor 401, and a driven gear 403 meshes with one side of the drive gear 402. The driven gear 403 is fixed to one end of the hinge shaft. Driven by the motor 401 and under the meshing action of the drive gear 402 and the driven gear 403, the upper shell 2 is rotated, thereby folding the part of the upper shell that protrudes above the cleaning machine 1, reducing the overall height and size, and thus facilitating movement.

[0029] When cleaning, a brush is needed to improve the cleaning effect on the exterior of the vehicle. However, because the vehicle's shape is curved, some brush bristles may not be able to reach the exterior, resulting in some areas being missed. To address this issue, please refer to... Figure 6The brush disc mechanism 5 includes a mounting frame 501. Multiple brush units 502 arranged side-by-side are rotatably connected to the top of the mounting frame 501. A second motor 503 is mounted at the bottom of the mounting frame 501. The output shaft of the second motor 503 is fixedly connected to the brush unit 502 located in the middle. A drive wheel 504 is also fixedly mounted on the output shaft of the second motor 503. Driven wheels 505 are connected to both sides of the drive wheel 504 via belt drive. The two driven wheels 505 are respectively fixedly connected to the brush units 502 located on both sides. Further, the brush unit 502 includes components rotatably connected to the mounting frame 501. The rotating shaft 5021 on 01 has a spring 5023 sleeved on its outer wall. A movable shaft 5022 is movably connected to the rotating shaft 5021, and a brush disc 5024 is fixed on the top of the movable shaft 5022. The motor 503 works and the driving wheel 504 and driven wheel 505 drive the multiple brush units 502 to rotate synchronously. At the same time, under the action of the spring 5023, the multiple brush units 502 can have a certain degree of floating effect, which can better fit the outside of the vehicle and reduce the damage to the outside of the vehicle during the cleaning process.

[0030] Because water stains remain on the exterior of the vehicle after washing, the cleaning effect may be incomplete. For this issue, please refer to... Figure 7 The wiper mechanism 6 includes a hinge block 601, on which an elastic sheet 602 is fixed. An elastic sheet 603 is hinged to both ends of the elastic sheet 602. The two elastic sheets 603 are respectively hinged to the bottom of both ends of the wiper blade 604. Under the action of the wiper blade 604, water can be wiped off the cleaned exterior wall of the vehicle. Under the action of the elastic sheet 602 and the elastic sheet 603, the wiper blade 604 also has a certain floating effect, which can better fit the exterior of the vehicle.

[0031] Furthermore, an air jet pipe 7, a cleaning agent pipe 8, and a water pipe 9 are installed inside both the upper housing 2 and the lower housing 3. The air jet pipe 7 and the water pipe 9 are located on one side of the double-row brush disc mechanism 5, and the cleaning agent pipe 8 is located between the double-row brush disc mechanisms 5. During cleaning, the cleaning agent is first sprayed onto the outside of the vehicle through the cleaning agent pipe 8. Then, the cleaning agent cleans the outside of the vehicle under the action of the brush disc mechanism 5. After cleaning, the cleaning agent and stains are rinsed off together through the water pipe 9. After rinsing, the air jet pipe 7 sprays high-pressure gas to dry the remaining water stains.

[0032] Furthermore, a controller 10 and a handle 11 are installed on the side wall of the cleaning machine 1; the controller 10 allows the operator to easily control the overall operation, while the handle 11 allows the operator to easily push the entire machine to move.

[0033] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
