Description

TECHNICAL FIELD

[0001] The present application relates to the field of cleaning vehicles, in particular to a recycling device for a cleaning vehicle, a train carriage cleaning vehicle and a cleaning method. BACKGROUND

[0002] Raw materials such as coal and iron ore are transported by freight trains across regions and long distances to reach the destination. After the raw materials are unloaded by the dumper, some residual materials remain on the surface of the carriage. If not cleaned in time, it will not only cause waste of energy, but also increase transportation costs, which does not meet the management requirements of the railway department for the car body. Currently, the residual materials in the carriage are mainly cleaned by manual labor. It usually takes more than 15 minutes to clean a section of empty carriage, which is low in work efficiency and high in labor intensity.

[0003] In the prior art, a Chinese invention patent with patent application publication number CN 113879868 A discloses an automatic cleaning device for a train freight carriage, which comprises a horizontal moving platform, a multi-degree-of-freedom manipulator and a negative pressure adsorption and dust removal mechanism installed on the horizontal moving platform. The negative pressure adsorption and dust removal mechanism comprises a pipeline, a fan motor, a fan and a dust storage bin fixed on the platform. One end of the pipeline extends to the side of the brush assembly, and the other end of the pipeline is connected to the dust storage bin. The fan motor is connected to the fan, and the fan is installed on the pipeline. This technical solution can realize automatic recycling and cleaning of residual materials in the train carriage through the cooperation of the multi-degree-of-freedom manipulator and the negative pressure adsorption and dust removal mechanism.

[0004] When the above technical solution is adopted, the following problems exist in direct adsorption through the pipeline. Since the pipeline is fixed on the manipulator structure, the relative position of the suction port and the brush assembly is relatively fixed, which leads to that the adsorption range is seriously dependent on the movement trajectory of the manipulator. The single-pipeline fixed-point adsorption mode cannot effectively adsorb and recycle the debris far from the suction port, resulting in incomplete cleaning of the carriage. SUMMARY

[0005] In order to solve the technical problem of incomplete cleaning of the carriage caused by poor adsorption and recycling effect of the carriage cleaning device in the prior art, the present application provides a recycling device for a cleaning vehicle, a train carriage cleaning vehicle and a cleaning method, which can comprehensively cover the bottom of the carriage, form comprehensive suction and recycling, and improve the cleaning effect of the train carriage.

[0006] In a first aspect, the present application provides a recycling device for a cleaning vehicle to solve the above technical problems, comprising a collecting tank and a fan in communication, and further comprising a recycling assembly, the recycling assembly comprising a suction nozzle and a suction cover in communication, the suction nozzle being in communication with the collecting tank, the length of the suction cover being greater than three fourths of the width of the cleaning vehicle cabin, two horizontal roller brushes being rotatably arranged in the suction cover, the suction port of the suction nozzle being located between the two horizontal roller brushes, the horizontal roller brushes being capable of pushing the dirt on the bottom of the cleaning vehicle cabin towards the suction nozzle, and the two horizontal roller brushes being suitable for cleaning the cleaning vehicle in two opposite directions of movement.

[0007] The present application effectively restrains the dust and dirt generated during the rotation cleaning of the horizontal roller brushes in a relatively closed space through the suction cover, prevents the scattering of the dirt, and forms a local negative pressure environment, while the long cover structure provides a stable suction channel for the suction nozzle, ensures that the dirt can smoothly converge to the suction port of the suction nozzle under the directional pushing of the horizontal roller brushes, significantly improves the suction efficiency, avoids the problem of incomplete suction of the material, and simultaneously, the two horizontal roller brushes arranged symmetrically in the suction cover can push the dirt towards the centrally arranged suction nozzle when the cleaning vehicle moves forward and reversely, realizes the structural integration, reduces the complexity, and significantly improves the operation convenience and space utilization rate while ensuring complete cleaning.

[0008] Further, the suction nozzle comprises a suction part, the suction part being connected with the middle part of the suction cover, the longitudinal section of the suction part being in isosceles trapezoidal structure, and the wide end of the suction part being the same length as the suction cover.

[0009] The present application can significantly accelerate the airflow speed and improve the negative pressure suction efficiency by designing the suction part of the suction nozzle as an isosceles trapezoidal structure in longitudinal section and the wide end being the same length as the suction cover, the matching of the wide end and the full length of the suction cover ensures smooth transition and dead angle-free coverage when the dirt converges from both ends to the middle part of the suction cover, reduces the airflow resistance loss, and avoids the vortex phenomenon easily generated by the traditional circular suction nozzle, thereby improving the suction efficiency and significantly reducing the energy consumption under the same fan power.

[0010] Further, the suction nozzle further comprises a transition part, the upper part of the transition part being in communication with the collecting tank through a recycling pipe, the lower part of the transition part being in communication with the narrow end of the suction part, the transition part being a variable cross-section structure, the upper part of the transition part being in circular structure, the lower part of the transition part being in rectangular structure, and the upper end diameter of the transition part being smaller than the length of the lower part.

[0011] This invention achieves optimized integration of the airflow channel through the variable cross-section design of the transition section. The upper circular cross-section of the transition section is seamlessly connected with the recovery pipe to reduce airflow resistance loss, while the lower rectangular cross-section forms a smooth transition with the isosceles trapezoidal structure at the narrow end of the suction section to maintain negative pressure stability. This gradual cross-section design from circular to rectangular effectively solves the problem of vortex generation at irregular interfaces, reduces airflow loss while ensuring the airflow acceleration effect, and significantly improves the energy utilization efficiency of the entire suction system.

[0012] Furthermore, the suction hood includes two opposing upright plates, with support wheels rotatably mounted on the upright plates. A floating connecting seat is provided at the upper end of the suction hood, which can be connected to the mounting frame of the cleaning device and can move up and down on the mounting frame.

[0013] This invention enables the suction hood to move smoothly along the bottom of the vehicle and adapt to uneven surfaces through the coordinated operation of support wheels and floating connecting seats. The floating connecting seats ensure that the suction hood always maintains a reasonable distance from the bottom of the vehicle to avoid collisions. By replacing the complex sensor control system with mechanical self-adaptation, the invention significantly reduces the complexity of the equipment and maintenance costs while improving the thoroughness of debris recycling.

[0014] Furthermore, an upper housing is provided between the two upright plates. The upper housing includes two arc surfaces connected by a connecting plate. The suction nozzle is provided on the connecting plate. The two horizontal roller brushes are respectively provided on the lower part of the corresponding arc surfaces. A guide plate is oscillatingly provided on the lower part of the connecting plate and between the two horizontal roller brushes. A swing rod is provided through the middle of the upper end of the guide plate. The end of the swing rod is rotatably provided on the corresponding upright plate. One end of the swing rod is connected to a hydraulic motor. The hydraulic motor is provided on the corresponding upright plate.

[0015] This invention achieves airflow guidance control through the synergy of the upper shell and the adjustable air guide plate. The two arc-shaped structures provide an optimized working space for the horizontal roller brush and form a flow channel. The swinging air guide plate can adjust the angle in real time according to the sweeping direction, ensuring that an effective negative pressure space can be formed inside the suction hood no matter which direction the sweeper moves, reducing leakage and ensuring that debris is always effectively guided to the suction nozzle.

[0016] Secondly, the present invention also provides a train carriage cleaning vehicle, including a cleaning device, the cleaning device including a mounting frame and a cleaning brush assembly, a mobile chassis and the aforementioned cleaning vehicle recycling device, the mobile chassis being provided with wheels, the collection box and the fan being provided on the mobile chassis, the mobile chassis being provided with a support frame, the support frame being provided with a lifting frame being raised and lowered, the lifting frame being provided with a swing arm being rotatably mounted, the axis of rotation of the swing arm being vertically arranged, the swing arm being provided with a mounting frame for the cleaning device, and the cleaning vehicle recycling device being provided at the bottom of the mounting frame.

[0017] This invention achieves comprehensive optimization of cleaning operations. The mobile chassis enables the equipment to move autonomously without relying on fixed tracks. The rigid support structure formed by the lifting frame and the swing arm ensures that the cleaning device can stably enter the working area of ​​the carriage. The recycling device integrated at the bottom of the mounting frame achieves comprehensive coverage and recycling of debris at the bottom of the carriage through its extra-long dust cover and bidirectional horizontal roller brush design. This high degree of synergy between the mechanical structure and the recycling system not only solves the problem of incomplete cleaning caused by the limited adsorption range of traditional solutions, but also significantly reduces the complexity of the equipment.

[0018] Furthermore, the cleaning device includes two cleaning brush assemblies, which are arranged on both sides of the mounting frame along the length of the carriage to be cleaned. Each cleaning brush assembly includes two vertically arranged vertical roller brushes, which are arranged on the mounting frame along the width direction of the carriage to be cleaned. Horizontal drive members are provided on both sides of the mounting frame, and the horizontal drive members are connected to the two vertical roller brushes on the same side. The two vertical roller brushes on the same side can move towards each other and away from each other along the width direction of the carriage to be cleaned.

[0019] This invention, by arranging two cleaning brush assemblies opposite each other along the length of the vehicle body, can clean the two vertical walls of the vehicle body along the width direction without changing the direction of movement of the mobile chassis. It does not require turning the direction of the mobile chassis or the cleaning device, simplifying the operation and the structure of the sweeper, making it more convenient to use. The two vertical roller brushes in each cleaning brush assembly, arranged on opposite sides, cancel out the horizontal reaction force given by the vehicle body when working on one side, significantly improving the thoroughness of cleaning and the stability of the equipment.

[0020] Furthermore, a disc brush is also provided at the lower part of the vertical roller brush. The disc brush has a frustum structure. Both the vertical roller brush and the disc brush are set on the same vertical rotating shaft. When the vertical roller brush is located at the outermost side of the mounting frame, the center of the disc brush is opposite to the corresponding end of the suction hood.

[0021] This invention effectively cleans the dead corners at the junction of the vertical wall and the bottom surface through the disc brush. At the same time, the conical guiding effect of the disc brush allows the debris to enter the suction hood recycling area more smoothly, solving the technical problem of the difficulty in recycling the accumulated material at the edge of the carriage.

[0022] Furthermore, the mobile chassis is also equipped with a driver's cab and a generator. The driver's cab includes a control module, which includes an image processing and analysis unit and a computing unit. Cameras are installed on the mobile chassis, the upper part of the swing arm, and the mounting frame. The cameras are electrically connected to the control module. The control module is electrically connected to the cleaning device, the fan, and the traveling wheels. The traveling wheels are electrically driven AG steering wheels. The control module is also electrically connected to an input unit.

[0023] This invention uses a multi-camera array distributed on a mobile chassis, swing arm, and mounting frame to collect real-time environmental data inside and outside the vehicle. The image processing and analysis unit uses deep learning algorithms to identify the cleanliness of the vertical walls, the distribution of residues, and the relative position of the equipment. Based on the analysis results, the calculation unit coordinates the movement path of the AGV steering wheel, the working angle of the swing arm, and the operating parameters of the cleaning device, thereby improving both the thoroughness and efficiency of cleaning.

[0024] Thirdly, the present invention also provides a method for cleaning train carriages, using the aforementioned train carriage cleaning vehicle, comprising the following steps: S01: Input the width and length of the vehicle compartment to be cleaned; S02: The mobile chassis automatically adjusts its position to maintain a set distance between the edge of the mobile chassis and the cleaning compartment and a set distance between the end of the mobile chassis and the end of the cleaning compartment, and adjusts the position of the two vertical roller brushes on the same side so that the two vertical roller brushes on the same side move towards each other and stop at the middle position of the mounting frame. S03: The cleaning device extends into the interior of the vehicle compartment; S04: Control the vertical roller brush to move to the set position and rotate to start cleaning, while the blower starts working; S05: Move the chassis at a set speed; S06: When the cleaning device moves to the other end of the carriage, if it is necessary to clean again, control the mobile chassis to move in the opposite direction and adjust the position of the vertical roller brush to perform a second reverse cleaning. S07: When it is determined that the cleaning device has finished cleaning, the swing arm returns to its original position.

[0025] As can be seen from the above technical solutions, the present invention has the following advantages: This invention provides a sweeper recycling device, a train carriage sweeper, and a sweeping method. The suction hood effectively confines dust and debris generated during the rotation of the horizontal roller brush within a relatively enclosed space, preventing debris from scattering and creating a localized negative pressure environment. Simultaneously, its elongated hood structure provides a stable suction channel for the suction nozzle, ensuring that debris, propelled directionally by the horizontal roller brush, smoothly converges along the inside of the hood to the suction port, significantly improving suction efficiency and avoiding incomplete material removal. Furthermore, the two symmetrically arranged horizontal roller brushes within the suction hood push debris towards the centrally located suction nozzle during forward and reverse movement of the sweeper, achieving structural integration and reducing complexity. This significantly improves operational convenience and space utilization while ensuring thorough cleaning. The transition section and suction section ensure airflow acceleration while minimizing airflow loss, significantly improving the energy efficiency of the entire suction system. The coordinated operation of the support wheels and floating connecting seat allows the suction hood to move smoothly along the carriage floor and adapt to uneven surfaces. The floating connecting seat further enhances the suction efficiency. The suction hood maintains a reasonable distance from the bottom of the truck bed to avoid collisions. Airflow guidance is controlled through the collaboration of the upper shell and adjustable air guide vanes. Two curved structures provide optimized working space for the horizontal roller brush while forming a flow channel. The swinging air guide vanes can adjust their angle in real time according to the cleaning direction, ensuring an effective negative pressure space is formed inside the suction hood regardless of the direction the sweeper moves, reducing leakage and ensuring that debris is always effectively guided to the suction nozzle. Thorough cleaning of the truck bed is achieved through the collaboration of the mobile chassis, cleaning device, and recovery device. Two cleaning brush assemblies are arranged opposite each other along the length of the truck bed, allowing cleaning of the two vertical walls along the width direction of the truck bed while maintaining the same direction of movement of the mobile chassis. This eliminates the need to reverse the direction of the mobile chassis or cleaning device, simplifying operation and the sweeper's structure, making it more convenient to use. The disc brush effectively cleans the dead corners at the junction of the vertical walls and the bottom surface. Simultaneously, the conical guiding action of the disc brush allows debris to enter the suction hood recovery area more smoothly, solving the technical problem of difficult recovery of accumulated material at the edges of the truck bed.

Detailed Implementation

[0037] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0038] Example 1 like Figure 1 and Figure 4As shown, this embodiment provides a recycling device for a sweeper, including a collection box 4, a blower 5, and a recycling assembly. The collection box 4 and the blower 5 are connected by a duct. The recycling assembly includes a suction nozzle 34 and a suction hood 15 that are connected to each other. The suction nozzle 34 is connected to the collection box 4. The length of the suction hood 15 is greater than three-quarters of the width of the sweeper compartment. Two horizontal roller brushes 17 are rotatably arranged inside the suction hood 15. The suction port of the suction nozzle 34 is located between the two horizontal roller brushes 17. The horizontal roller brushes 17 can push the debris at the bottom of the sweeper compartment toward the suction nozzle 34. The two horizontal roller brushes 17 are respectively suitable for two opposite sweeping movement directions of the sweeper.

[0039] In this embodiment, the suction hood 15 effectively confines the dust and debris generated by the rotating sweeping of the horizontal roller brush 17 within a relatively enclosed space, preventing debris from scattering and creating a local negative pressure environment. At the same time, its long hood structure provides a stable and large-area adsorption channel for the suction nozzle 34, ensuring that debris can smoothly converge into the suction port of the suction nozzle 34 under the directional push of the horizontal roller brush 17, significantly improving suction efficiency and avoiding the problem of incomplete material suction. In addition, the two horizontal roller brushes 17 symmetrically arranged inside the suction hood 15 can push debris towards the centrally arranged suction nozzle 34 when the sweeper moves forward and backward, respectively, achieving structural integration, reducing complexity, and significantly improving operational convenience and space utilization while ensuring thorough cleaning.

[0040] like Figure 2 and Figure 3 As shown, to improve suction efficiency, in this embodiment, the suction nozzle 34 includes a suction section 35 and a transition section 36. The suction section 35 is connected to the middle of the suction cover 15. The longitudinal section of the suction section 35 is an isosceles trapezoidal structure, and the wide end of the suction section 35 is the same length as the suction cover 15. The upper part of the transition section 36 is connected to the collection box 4 through a recovery pipe 31, and the lower part of the transition section 36 is connected to the narrow end of the suction section 35. The transition section 36 has a variable cross-section structure, with a circular cross-section at the upper part and a rectangular cross-section at the lower part. The diameter of the upper end of the transition section 36 is... The length is less than that of the lower part; this setting can significantly accelerate the airflow speed and improve the negative pressure suction efficiency. The wide end of the suction nozzle 34 matches the full length of the suction hood 15 to ensure a smooth transition and no dead angle coverage when debris gathers from both ends of the suction hood 15 to the middle. The transition part 36 adopts a variable cross-section structure, which effectively solves the problem of vortex generation at the irregular interface. While ensuring the airflow acceleration effect, it reduces airflow loss and significantly improves the energy utilization efficiency of the entire suction system. In this embodiment, the suction part 35 and the transition part 36 are welded integrated structures, and both the suction part 35 and the transition part 36 are cast structures. The air duct and the recovery pipe 31 are both telescopic flexible hoses.

[0041] Because the bottom of the train carriage has a reinforcing section, it is uneven. To prevent the bottom of the carriage from colliding with the suction hood 15 during cleaning, such as... Figure 1 and Figure 4 As shown, in this embodiment, the suction hood 15 includes two opposing upright plates 42, with support wheels 25 rotatably mounted on the upright plates 42. A floating connecting seat 27 is provided at the upper end of the suction hood 15. The floating connecting seat 27 can be connected to the mounting frame 11 of the cleaning device. The floating connecting seat 27 can move up and down on the mounting frame 11. Specifically, the floating connecting seat 27 is provided with two pins 28, which pass through pin holes 29 at the bottom of the mounting frame 11. The pin holes 29 are vertically arranged straight slots, and limit nuts are provided at both ends of the pins 28. The pins 28 can move up and down within the pin holes 29. With this configuration, the floating connecting seat 27 can move up and down under the action of the vehicle bottom and the gravity of the recycling component itself, adapting to uneven surfaces and avoiding collisions. By replacing the sensor control system with mechanical adaptation, the thoroughness of debris recycling is improved while significantly reducing equipment complexity and maintenance costs.

[0042] like Figure 2 and Figure 3As shown, in this embodiment, an upper housing 41 is provided between the two upright plates 42. The upper housing 41 includes two arc surfaces connected by a connecting plate 43. The suction nozzle 34 is disposed on the connecting plate. The two horizontal roller brushes 17 are respectively disposed on the lower part of the corresponding arc surfaces. Two driving components 26 are also provided on the upright plates 42. The driving components 26 are hydraulic motors and are connected to the horizontal rotating shafts of the corresponding horizontal roller brushes 17 through couplings. The horizontal rotating shafts 33 are disposed on the upright plates 42 through bearings. The horizontal rotating shafts 33 are connected to the water... The horizontal roller brushes 17 are coaxially arranged. Since the rotation of the two horizontal roller brushes 17 in this recycling assembly is related to the direction of movement of the sweeper, it is always necessary to ensure that the horizontal roller brushes 17 in front of the suction nozzle 34 rotate along the direction of movement, pushing debris from the bottom of the vehicle and the sweeping device towards the suction nozzle 34. The port of the suction nozzle 34, located at the rear of the direction of movement, will be exposed to the cleaned area. At this time, the strong negative pressure generated by the fan 5 will draw in a large amount of clean air through this port. This will directly lead to suction dispersion and a decrease in negative pressure, resulting in a decrease in airflow speed and weakening the suction. The suction power of the nozzle 34 makes it difficult to pick up heavier or more firmly attached debris. To solve this problem, in this embodiment, a guide plate 37 is oscillatingly arranged at the lower part of the connecting plate 43 and between the two horizontal roller brushes 17. During the recycling operation, the lower end of the guide plate 37 always moves closer to the rotating horizontal roller brushes 17. Specifically, a swing rod 38 is provided through the middle of the upper end of the guide plate 37. The end of the swing rod 38 is rotatably mounted on the corresponding vertical plate 42 via a bearing. One end of rod 38 is connected to a hydraulic motor via a coupling. The hydraulic motor is mounted on the corresponding vertical plate. With this configuration, the upper housing 41 and the air guide plate 37 work together to control the airflow. The two arc-shaped structures provide an optimized working space for the horizontal roller brush 17 and form a flow channel. The swinging air guide plate 37 can adjust its angle in real time according to the sweeping direction, ensuring that no matter which direction the sweeper moves, an effective negative pressure space can be formed inside the suction hood 15 to reduce leakage and ensure that debris is always effectively guided to the suction nozzle 34.

[0043] Example 2 like Figures 5 to 8As shown, this embodiment provides a train carriage cleaning vehicle, including a cleaning device. The cleaning device includes a mounting frame 11 and a cleaning brush assembly 10, as well as a mobile chassis 21 and a recycling device for the cleaning vehicle of Embodiment 1. The mobile chassis 21 includes a frame 9, with four wheels 8 mounted on the lower part of the frame 9. The collection box 4 and the fan 5 are both mounted on the mobile chassis 21. A support frame 22 is also mounted on the mobile chassis 21. A lifting frame 20 is raised and lowered on the support frame 22, and a swing arm 3 is rotatably mounted on the lifting frame 20. The axis of rotation of the swing arm 3 is... The sweeping device is mounted on the vertically oriented swing arm 3, and the sweeper recovery device is located at the bottom of the mounting frame 11. Specifically, the support frame 22 is bolted to the movable chassis 21, and a lifting cylinder 39 is mounted on the support frame 22. The piston rod of the lifting cylinder 39 is connected to the lifting frame 20. The lifting frame 20 and the support frame 22 are connected by a guide rail slider mechanism. A rotary motor is mounted on the lifting frame 20, and a rotating disk 40 is connected to the rotating disk 40. The rotating disk 40 is connected to the end of the swing arm 3 through a connecting flange. The swing arm 3 has a U-shaped structure with the opening facing downwards.

[0044] In this embodiment, the cleaning device achieves three-dimensional movement through the mobile chassis 21, lifting frame 20, and swing arm 3, enabling cleaning of the carriage. The mobile chassis 21 allows the equipment to move autonomously without relying on fixed tracks, making it more convenient to use. The rigid support structure formed by the lifting frame 20 and swing arm 3 ensures that the cleaning device can stably enter the carriage working area. The recycling device achieves comprehensive coverage and recycling of debris at the bottom of the carriage through its extra-long dust cover and bidirectional horizontal roller brush 17 design. This high degree of synergy between the mechanical structure and the recycling system not only solves the problem of incomplete cleaning caused by the limited adsorption range of traditional solutions, but also improves the cleaning effect and significantly reduces the complexity of the equipment.

[0045] Because the two vertical walls of the carriage are positioned opposite each other in the width direction, using existing methods requires rotating 180° after cleaning one side before cleaning the other. This necessitates that the cleaning device have the ability to rotate around a vertical axis, increasing the degree of freedom of motion. This undoubtedly increases the complexity of the transmission system. To reduce structural complexity, such as... Figures 5 to 7As shown, in this embodiment, the cleaning device includes two cleaning brush assemblies 10. The two cleaning brush assemblies 10 are arranged on both sides of the mounting frame 11 along the length of the carriage to be cleaned. Each cleaning brush assembly 10 includes two vertically arranged vertical roller brushes 13. The two vertical roller brushes 13 are arranged on the mounting frame 11 along the width direction of the carriage to be cleaned. This arrangement allows for cleaning of the two width directions of the carriage without requiring a 180° rotation of the mounting frame 11, further simplifying the transmission system layout and making it more convenient to use. Simultaneously, it enables a two-stage cleaning mode with a single movement along the length of the vertical walls, improving cleaning effect and efficiency. Furthermore, the two vertical roller brushes 13 not only enhance cleaning... The cleaning efficiency is improved, and the symmetrical force design offsets the horizontal reaction force exerted on the vertical roller brush 13 by the carriage, fundamentally solving the deformation risk caused by unilateral force on the robotic arm in the prior art. This ensures the roller brush maintains a long-lasting and tight fit with the carriage wall, guaranteeing the cleaning effect. Furthermore, horizontal drive components 18 are provided on both sides of the mounting frame 11. The horizontal drive components 18 are connected to the two vertical roller brushes 13 on the same side. The two vertical roller brushes 13 on the same side can move towards and away from each other along the width direction of the carriage to be cleaned. Specifically, the horizontal drive component 18 is connected to two movable seats 19. The two movable seats 19 can move towards and away from each other along the width direction of the carriage. The drive component is provided on the movable seat 19. 12. A vertical rotating shaft 24 is vertically and rotatably mounted on the movable seat 19. The horizontal drive component 18 consists of two horizontally mounted hydraulic cylinders facing opposite directions. The piston rods of the two cylinders are respectively connected to the corresponding movable seats 19. The movable seats 19 are mounted on the mounting frame 11 via a guide rail slider mechanism. The movable seats 19 have an opening facing one end of the carriage. The vertical rotating shaft 24 is rotatably mounted inside the movable seat 19 via bearings. A drive component 12 is mounted on the upper part of the movable seat 19. The drive component 12 is a hydraulic motor. The output shaft of the hydraulic motor is connected to the end of the vertical rotating shaft 24 via a coupling. The center hole of the vertical roller brush 13 is connected to the vertical rotating shaft 24 via a spline. With this configuration, it can control the width direction of the carriage. The vertical roller brush 13 provides comprehensive cleaning without requiring the cleaning device to move laterally within the vehicle, significantly simplifying the power system layout and improving operational stability. Furthermore, a disc brush 14 with a truncated cone structure is provided below the vertical roller brush 13. Both the vertical roller brush 13 and the disc brush 14 are mounted on the same vertical rotating shaft 24. When the vertical roller brush 13 is located at the outermost edge of the mounting bracket 11, the center of the disc brush 14 is aligned with the corresponding end of the suction hood 15. The disc brush 14 effectively cleans the dead corners at the junction of the vertical roller brush and the bottom surface. At the same time, the conical guide effect of the disc brush 14 allows debris to enter the collection area of ​​the suction hood 15 more smoothly, solving the technical problem of difficult recovery of accumulated material at the edge of the vehicle.

[0046] The mobile chassis 21 is also equipped with a driver's cab 1 and a generator. The driver's cab 1 includes a control module, which includes an image processing and analysis unit and a computing unit. Cameras 16 are installed on the mobile chassis 21, the upper part of the swing arm 3, and the mounting frame 11. Multiple cameras 16 can collect road information, information on the distribution of debris inside the vehicle, and information on the position of the vehicle's walls. The cameras 16 are electrically connected to the control module, which is electrically connected to the sweeping device, the fan 5, and the traveling wheels 8. The traveling wheels 8 are electrically driven AG steering wheels, which are commercially available products and are existing technology, capable of achieving... The 360° rotation of the wheels greatly reduces the turning radius and enables lateral and longitudinal movement, making it suitable for use in narrow spaces. The control module is also electrically connected to an input unit and a display, with the input unit using a mouse and keyboard. A multi-camera array of 16 distributed on the mobile chassis 21, swing arm 3, and mounting frame 11 collects real-time environmental data inside and outside the vehicle. The image processing and analysis unit uses deep learning algorithms to identify the cleanliness of the vertical walls, the distribution of residues, and the relative position of the equipment. Based on the analysis results, the calculation unit coordinates the movement path of the AGV steering wheel, the working angle of the swing arm 3, and the operating parameters of the cleaning device, thereby improving both the thoroughness and efficiency of cleaning.

[0047] Because the sweeping device of this sweeper is side-mounted and the mobile chassis 21 moves forward via the wheels 8, there is a certain risk of tipping over. To solve this technical problem, such as... Figure 9 As shown, in this embodiment, the frame 9 is a rectangular frame structure. The height of the middle part of the frame 9 is lower than the height of its two ends. The collection box 4 is located in the middle of the frame 9. A generator is located in the middle of the frame 9. An energy storage battery and a driver's cab 1 are located at the front end of the frame 9. The energy storage battery is electrically connected to the fan 5 and the traveling wheels 8. The fan 5 is located at the rear end of the frame 9. The low center of gravity layout is achieved through the sunken rectangular frame structure in the middle of the frame 9, which optimizes the stability of the vehicle and the space utilization. The design of the middle part of the frame 9 being lower than the two ends allows heavy components such as the collection box 4 and the generator to be arranged in a sunken manner, which significantly lowers the center of gravity of the vehicle and enhances the anti-rollover capability of the mobile chassis 21 during steering or braking. It is especially suitable for the off-center load conditions caused by the lateral overhang operation of the sweeping device and the device that travels by the traveling wheels 8.

[0048] Example 3 This embodiment provides a method for cleaning train carriages, using the train carriage cleaning vehicle of Embodiment 2, and includes the following steps: S01: Input the width and length of the cleaning compartment. The preset compartment size parameters provide benchmark data for subsequent automatic operations, enabling rapid adaptation to different vehicle models. S02: The mobile chassis 21 automatically adjusts its position to maintain a set distance between the edge of the mobile chassis 21 and the cleaning compartment and a set distance between the end of the mobile chassis 21 and the end of the cleaning compartment, and adjusts the position of the two vertical roller brushes 13 on the same side so that the two vertical roller brushes 13 on the same side move towards each other and stop at the middle position of the mounting frame 11. S03: The cleaning device extends into the interior of the vehicle compartment; S04: Control the vertical roller brush 13 to move to the set position and rotate to start cleaning, while the blower 5 starts working; S05: Move chassis 21 at a set speed; S06: When the cleaning device moves to the other end of the carriage, if it is necessary to clean again, control the mobile chassis 21 to move in the opposite direction and adjust the position of the vertical roller brush 13 to perform a second reverse cleaning. S07: When it is determined that the cleaning device has finished cleaning, the swing arm 3 is reset.

[0049] In S04, the two vertical roller brushes 13 on the side away from the initial end of the car body wall are adjusted to the end of the mounting frame 11 according to the width of the car body, ensuring that they are in contact with the vertical wall in the length direction of the car body for cleaning. The two vertical roller brushes 13 on the other side move back and forth along the mounting frame 11 to clean the vertical wall in the width direction of the car body at the starting position. After cleaning, the reciprocating vertical roller brushes 13 move to a position aligned with the vertical roller brushes 13 on the other side to achieve a secondary cleaning of the vertical wall in the length direction. Then, in S05, the vertical wall in the length direction of the car body is cleaned.

[0050] In S06, when the cleaning device moves to the other end of the carriage (it can be determined by the vision camera whether to move to the other end of the carriage or by setting the moving distance based on the length of the carriage on the moving chassis 21), the two vertical roller brushes 13 on the other side are controlled to move back and forth to clean the vertical wall in the other width direction. After the vertical wall is cleaned, it is determined whether it needs to be cleaned again based on the images captured by the camera on the mounting frame 11 and the swing arm 3. If it needs to be cleaned again, the key position for cleaning is determined. At this key position, the rotation speed of the first drive component 12 and the second drive component 26 is increased, and the rotation speed of the fan 5 is increased to deal with the debris that is more firmly attached. The vertical roller brushes 13 on the corresponding side are adjusted to the corresponding position for cleaning, and the air guide plate 37 is rotated so that its lower end faces the other rotating horizontal roller brush 17.

[0051] In S07, when the swing arm 3 resets, the lifting frame 20 rises first, the swing arm 3 rotates in the opposite direction, and then the lifting frame 20 falls.

[0052] As can be seen from the above specific embodiments, the present invention has the following beneficial effects: 1. The suction hood 15 effectively confines the dust and debris generated by the horizontal roller brush 17 during rotation and cleaning within a relatively enclosed space, preventing debris from scattering and creating a local negative pressure environment. At the same time, its long hood structure provides a stable adsorption channel for the suction nozzle 34, ensuring that debris can smoothly converge into the suction port of the suction nozzle 34 under the directional push of the horizontal roller brush 17, significantly improving suction efficiency and avoiding the problem of incomplete material suction. In addition, the two horizontal roller brushes 17 symmetrically arranged inside the suction hood 15 can push debris towards the centrally arranged suction nozzle 34 when the sweeper moves forward and backward, respectively, achieving structural integration, reducing complexity, and significantly improving operational convenience and space utilization while ensuring thorough cleaning. 2. By using the transition section 36 and the suction section 35, the airflow acceleration effect is ensured while the airflow loss is reduced, which significantly improves the energy utilization efficiency of the entire suction system. Through the coordinated cooperation of the support wheel 25 and the floating connecting seat 27, the suction hood 15 can move smoothly along the bottom of the carriage and adapt to uneven surfaces. The floating connecting seat 27 ensures that the suction hood 15 always maintains a reasonable distance from the bottom of the carriage to avoid collision. 3. The airflow guidance is controlled by the cooperation of the upper shell and the adjustable air guide plate 37. The two arc structures provide an optimized working space for the horizontal roller brush 17 and form a guide channel. The swing air guide plate 37 can adjust the angle in real time according to the sweeping direction to ensure that no matter which direction the sweeper moves, an effective negative pressure space can be formed inside the suction hood 15 to reduce leakage and ensure that the debris is always effectively guided to the suction nozzle 34. 4. Through the coordinated operation of the mobile chassis 21, the sweeping device, and the recycling device, a thorough cleaning of the carriage can be achieved. With the two sweeping brush assemblies 10 arranged opposite each other along the length of the carriage, the two vertical walls along the width of the carriage can be cleaned while keeping the moving direction of the mobile chassis 21 unchanged. There is no need to turn the direction of the mobile chassis 21 or the sweeping device, which simplifies the operation and the structure of the sweeper and makes it more convenient to use. 5. The disc brush 14 can effectively clean the dead corners at the junction of the vertical wall and the bottom surface. At the same time, the conical guiding effect of the disc brush 14 allows the debris to enter the collection area of ​​the suction hood 15 more smoothly, solving the technical problem of the difficulty in recycling the accumulated material at the edge of the carriage.
