Description

Technical Field

[0001] This invention relates to the field of wheelset cleaning technology, and more particularly to a vehicle wheelset cleaning device and method. Background Technology

[0002] As a core component of the high-speed train's running system, the wheelset is used to bear the weight of the train, transmit driving torque, and provide guidance. Its operating condition directly affects the train's safety and efficiency. During long-term operation, the surface of the wheelset accumulates contaminants such as oil, iron filings, and dust due to friction with the track and external environmental corrosion. If not cleaned in time, this will accelerate the wear of the wheelset, affect the train's stability, and pose safety hazards. Furthermore, the accumulation of contaminants can lead to poor contact between the wheelset and the track, causing vibration and noise problems.

[0003] Currently, the cleaning of high-speed train wheelsets is mainly done manually. Cleaners use high-pressure water guns and brushes to clean each component of the wheelset one by one. This cleaning method is labor-intensive. Cleaners must work in relatively confined spaces such as train maintenance pits. Cleaning the bottom of the wheelsets requires prolonged bending and stooping, which easily leads to physical fatigue. Cleaning the top of the wheelsets requires cleaners to hold high-pressure water guns and spray water, further increasing the labor intensity. Furthermore, manual cleaning is inefficient, taking a long time to clean a single set of wheelsets, making it difficult to meet the needs of high-density railway vehicle maintenance. The quality of manual cleaning is also greatly affected by the operator's experience, easily resulting in incomplete cleaning, missed areas, and poor cleaning results. Summary of the Invention

[0004] The purpose of this invention is to provide a vehicle wheelset cleaning device and method, which reduces the labor intensity of cleaning personnel and improves the cleaning efficiency and effect of vehicle wheelsets.

[0052] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0053] The power train wheelset cleaning device and method provided by the present invention can reduce the labor intensity of cleaning personnel and improve the cleaning efficiency and effect of power train wheelsets.

[0054] like Figures 1 to 11As shown, the train wheelset cleaning device includes a guide rail 1, a cleaning mechanism 2, a displacement mechanism 3, and a support mechanism 4. The guide rail 1 is configured to hold the train wheelset 100. The cleaning mechanism 2 includes a first brushing assembly 21, a second brushing assembly 22, and nozzles. The first brushing assembly 21 includes a plurality of first roller brushes 211 spaced apart along a first direction. The first roller brushes 211 extend vertically and are configured to brush the sides and top surface of the train wheelset 100. The second brushing assembly 22 includes second roller brushes 221 extending horizontally. 1 is configured as the bottom surface of the roller brush wheel pair 100, and the nozzle is configured to spray high-pressure water jets onto the wheel pair 100; the displacement mechanism 3 includes a stop 31, a booster 32, a drive wheel 33 and a driven wheel 34, the stop 31 is connected to the guide rail 1 and configured to stop the wheel pair 100, the booster 32 is connected to the guide rail 1 and configured to boost the wheel pair 100, the drive wheel 33 is rotatably connected to the guide rail 1, the driven wheel 34 is rotatably connected to the guide rail 1, and the wheel pair 100 can roll on the drive wheel 33 and the driven wheel 34; the support mechanism 4 is configured to support the cleaning mechanism 2.

[0055] The power train wheelset cleaning device provided by this invention includes a guide rail 1, a cleaning mechanism 2, a displacement mechanism 3, and a support mechanism 4. The support mechanism 4 supports the cleaning mechanism 2, the guide rail 1 supports the power train wheelset 100 to be cleaned, and the displacement mechanism 3 includes a stop member 31, a pusher member 32, a driving wheel 33, and a driven wheel 34. In use, the stop member 31 stops the power train wheelset 100, the first brushing assembly 21 cleans the top of the power train wheelset 100, and the second brushing assembly 22 cleans the bottom of the power train wheelset 100. The rotation of the driving wheel 33 allows the power train wheelset 100 to rotate between the driving wheel 33 and the driven wheel 34, enabling the first brushing assembly 21 and the second brushing assembly 22 to clean more areas of the power train wheelset 100, avoiding the problem of uncleaned areas and improving the cleaning effect. After cleaning, the pusher member 32 pushes the power train wheelset 100 to roll away from the cleaning area, and the cleaning mechanism 2 and the displacement mechanism 3 clean subsequent power train wheelsets 100 to be cleaned, improving the cleaning efficiency.

[0056] It should be noted that the nozzle is a conventional component in this field, and its structure, connection method and operation method are conventional settings, which will not be described in detail here.

[0057] This embodiment does not specifically limit the shape of the guide rail 1. For example, see [link to example]. Figure 6 The cross-section of the guide rail 1 is I-shaped. The upper and lower flanges of the I-shaped guide rail 1 can distribute the load, and the middle web increases the overall rigidity of the structure, thereby improving the bending moment resistance and bearing a large vertical load and horizontal impact force.

[0058] The guide rail 1 can be supported by a support device so that the guide rail 1 is suspended in the air, and the second scrubbing component 22 is placed between the two guide rails 1; the guide rail 1 can also be set on the ground, and a hole is dug in the ground between the two guide rails 1 to place the second scrubbing component 22.

[0059] The first brushing assembly 21 is used to brush the top of the train wheelset 100. Exemplarily, the first brushing assembly 21 further includes a drive cylinder 212, a first connector 213, a second connector 214, and a third connector 215. The cylinder seat of the drive cylinder 212 is fixedly connected to the first connector 213. The first connector 213 is slidably connected to the second connector 214 along a first direction. The second connector 214 is slidably connected to the support mechanism 4 along a second direction. The piston rod of the drive cylinder 212 passes sequentially through the first connector 213, the second connector 214, and the third connector 215, and is fixedly connected to the third connector 215. The bottom end of the third connector 215 is rotatably connected to a first roller brush 211. The first direction is perpendicular to the second direction. (The first direction is as follows...) Figure 3 As shown in the X direction, the second direction is as follows: Figure 3 As shown in the Y direction. The drive cylinder 212 causes the first roller brush 211 to move in the vertical direction, the first connecting member 213 causes the first roller brush 211 to move in the first direction, and the second connecting member 214 causes the first roller brush 211 to move in the second direction, thereby increasing the working range of the first roller brush 211 and thus improving the cleaning effect and cleaning efficiency of the moving wheelset 100.

[0060] In use, when the second connector 214 slides along the second direction, the piston rod of the drive cylinder 212 passes through the first connector 213, the second connector 214, and the third connector 215 in sequence. Therefore, the third connector 215 moves with the second connector 214, thereby driving the first roller brush 211 to move along the second direction. When the first connector 213 moves along the first direction, the piston rod of the drive cylinder 212 passes through the first connector 213, the second connector 214, and the third connector 215 in sequence. Therefore, the third connector 215 moves with the first connector 213, thereby driving the first roller brush 211 to move along the first direction. The extension and retraction of the piston rod of the drive cylinder 212 can drive the third connector 215 to move in the vertical direction, thereby driving the first roller brush 211 to move in the vertical direction.

[0061] This embodiment does not specifically limit the shapes of the first connector 213, the second connector 214, and the third connector 215. For example, see [link to example]. Figure 3 and Figure 4 The first connecting member 213 is plate-shaped, which facilitates the support of the drive cylinder 212. The second connecting member 214 is a frame structure, which facilitates the insertion of the piston rod of the pneumatic cylinder. The first connecting member 213 is plate-shaped, which facilitates the connection of the first roller brush 211.

[0062] The first connector 213 and the second connector 214 can be slidably connected via a slide rail or a slider groove. For example, the top of the second connector 214 has two first sliders 6 spaced apart along a second direction, each extending along a first direction. The bottom of the first connector 213 has two first connecting seats 7 spaced apart along the first direction on each side along the second direction. Each first connecting seat 7 has a first groove along the first direction, allowing the first sliders 6 to slide within the first groove. The multiple first connecting seats 7 can evenly distribute the load, preventing damage from excessive force, improving the service life of the first connecting seats 7, and thus ensuring smooth sliding of the first connector 213 onto the second connector 214.

[0063] The second connector 214 and the support mechanism 4 can be slidably connected via a slide rail or a slider groove. For example, the support mechanism 4 includes a support leg 41 and a support beam 42. The support leg 41 is fixedly connected to the bottom end of the support beam 42, which extends along a second direction. A guide slider 5 is provided at the top end of the support beam 42 along the second direction, and the second connector 214 is slidably connected to the guide slider 5. The guide slider 5 guides the second connector 214, ensuring that the second connector 214 moves along the second direction.

[0064] Four support legs 41 are provided, distributed along a rectangle and located at the four corner points of the rectangle. A support beam 42 is fixedly connected to the top of two support legs 41 located on the same side of the rectangle. The two support beams 42 are spaced apart along a first direction, and a support longitudinal beam 43 connects the two support beams 42 to improve stability. The four support legs 41 evenly bear the weight of the support beams 42, preventing excessive stress on any single support leg 41 and extending its service life.

[0065] Specifically, on each side of the bottom end of the second connector 214, which is spaced apart along the first direction, two second connector seats 8 are provided at intervals along the second direction. Each second connector seat 8 has a second groove along the second direction. The guide slider 5 can slide in the second groove. Multiple second connector seats 8 can evenly distribute the load, avoid damage due to excessive force, improve the service life of the second connector seats 8, and thus ensure that the second connector 214 slides smoothly on the support beam 42.

[0066] This embodiment does not specifically limit the number of drive cylinders 212. For example, the first brushing assembly 21 includes two drive cylinders 212, which are spaced apart along a first direction on the first connecting member 213. The two drive cylinders 212 evenly bear the load, reducing the load on a single drive cylinder 212 and improving its service life. Simultaneously, the piston rods of the two drive cylinders 212 are fixedly connected to the third connecting member 215, preventing the third connecting member 215 from twisting and jamming. The synchronous lifting and lowering of the piston rods of the two drive cylinders 212 prevents the third connecting member 215 from tipping over and jamming, improving the smoothness of the lifting and lowering process of the first roller brush 211.

[0067] In other embodiments, the first scrubbing assembly 21 may also include three drive cylinders 212.

[0068] The second scrubbing assembly 22 is used to clean the bottom of the train wheelset 100. In this embodiment, see [link to documentation]. Figure 1 and Figure 6 The second scrubbing assembly 22 also includes a support column 222, a lifting member 223, and a support plate 224. The support column 222 extends vertically, and the top of the support column 222 is provided with a lifting member 223. The other end of the lifting member 223 is fixedly connected to the support plate 224. The lifting member 223 can drive the support plate 224 to rise and fall vertically. The support plate 224 is connected to a second roller brush 221 to increase the scrubbing range of the second roller brush 221.

[0069] Specifically, see Figure 6 The second brushing assembly 22 also includes a first drive motor 225, a drive screw 226, a drive nut 227, a movable plate 228, and a second drive motor 229. The first drive motor 225 is fixedly connected to the support plate 224. The first drive motor 225 is driven by the drive screw 226, which extends along a second direction. The drive nut 227 is screwed onto the drive screw 226. The movable plate 228 is fixedly connected to the drive nut 227. The second drive motor 229 and a second roller brush 221 are mounted on the movable plate 228. The second drive motor 229 is configured to drive the second roller brush 221 to rotate at the bottom of the roller brush drive wheelset 100.

[0070] In use, the lifting component 223 can drive the support plate 224 to rise and fall vertically, thereby driving the second roller brush 221 to rise and fall. The first drive motor 225 operates to rotate the drive screw 226, and the drive nut 227 moves along the axial direction of the drive screw 226. The moving plate 228 moves with the drive nut 227, thereby driving the second drive motor 229 and the second roller brush 221 on the moving plate 228 to move.

[0071] Optionally, both the first drive motor 225 and the second drive motor 229 are existing motors that are readily available and easy to use.

[0072] Specifically, the second brushing assembly 22 also includes a rotating shaft, which is connected to the second drive motor 229. The second roller brush 221 is fixedly connected to the rotating shaft along the circumference of the rotating shaft. The second drive motor 229 can drive the rotating shaft to rotate, thereby causing the second roller brush 221 on the rotating shaft to brush the wheelset 100.

[0073] It should be noted that, in order to ensure that the second roller brush 221 can move along the length of the guide rail 1, the end of the rotating shaft away from the second drive motor 229 can be suspended or slidably connected to the guide rail 1 to improve stability.

[0074] To further improve the cleaning effect on the train wheelset 100, the train wheelset cleaning device also includes a third brushing assembly 23. The third brushing assembly 23 includes a fourth connector 231, a fifth connector 232, a sixth connector 233, and a third roller brush 234. The fourth connector 231 extends along a first direction and is slidably connected to the support mechanism 4 along a second direction. The fifth connector 232 extends vertically and is slidably connected to the fourth connector 231 along a first direction. The sixth connector 233 is slidably connected to the fifth connector 232 along a vertical direction. The bottom end of the sixth connector 233 is rotatably connected to the third roller brush 234. The fourth connector 231 causes the third roller brush 234 to move along the second direction, the fifth connector 232 causes the third roller brush 234 to move along the first direction, and the sixth connector 233 causes the third roller brush 234 to move along the vertical direction.

[0075] The fourth connector 231 and the support mechanism 4 can be slidably connected via a slide rail or a slider groove. For example, two third connecting seats are spaced apart at the bottom of the fourth connector 231, each with a third groove along the second direction. The guide slider 5 can slide within the third groove, providing guidance for the fourth connector 231 and ensuring it slides along the second direction.

[0076] Furthermore, the third scrubbing assembly 23 also includes a support plate 235, a guide rack 236, a third drive motor 237, and a guide gear 238. The fourth connector 231 is fixedly provided with the guide rack 236 along the first direction. The fifth connector 232 is fixedly connected to the support plate 235. The support plate 235 is provided with the third drive motor 237. The output shaft of the third drive motor 237 is fixedly connected to the guide gear 238. The guide gear 238 can mesh with the guide rack 236. The meshing of the guide gear 238 and the guide rack 236 is stable, improving the connection stability.

[0077] In use, the third drive motor 237 operates, and the output shaft of the third drive motor 237 drives the guide gear 238 to rotate. The guide gear 238 meshes with the guide rack 236. Since the guide rack 236 is fixedly connected to the fourth connector 231, and the fourth connector 231 is slidably connected to the support beam 42 in the second direction, restricting the movement of the guide rack 236 in the first direction, the guide gear 238 will move during the process of meshing with the guide rack 236, thereby driving the bearing plate 235 to move. The bearing plate 235 is fixedly connected to the fifth connector 232, thereby driving the fifth connector 232 to move in the first direction, and thus driving the third roller brush 234 to move in the first direction.

[0078] The displacement mechanism 3 is used to control the state of the wheelset 100, improving the cleaning efficiency and effect of the cleaning mechanism 2 on the wheelset 100. In this embodiment, the displacement mechanism 3 also includes a first driving member 35 and a second driving member 36. One end of the stop member 31 is tractively connected to the first driving member 35, and the other end is rotatably connected to the guide rail 1. The first driving member 35 can drive the stop member 31 to rotate away from the guide rail 1 to stop the wheelset 100. The second driving member 36 is tractively connected to one end of the pusher member 32, and the other end of the pusher member 32 is rotatably connected to the guide rail 1. The second driving member 36 can drive the pusher member 32 to rotate away from the guide rail 1 to push the wheelset 100. The stop member 31 stops the wheelset 100, ensuring that the cleaning mechanism 2 cleans the wheelset 100. After cleaning, the pusher member 32 pushes the wheelset 100, improving the cleaning efficiency.

[0079] In other embodiments, the stop member 31 may also be slidably connected to the guide rail 1 in a vertical direction. The stop member 31 slides upward to stop the wheelset 100 and slides downward to avoid the wheelset 100. The pusher member 32 may also be slidably connected to the guide rail 1 in a vertical direction. The pusher member 32 slides upward to push the wheelset 100 and slides downward to avoid the wheelset 100.

[0080] This embodiment does not specifically limit the shape of the stop 31 and the booster 32. For example, the stop 31 is a stop block and the booster 32 is a booster block. They have high strength and can improve the service life of the stop 31 and the booster 32.

[0081] Specifically, the stop member 31 includes an arc-shaped groove that can fit against the surface of the wheelset 100. The arc-shaped groove fits against the surface of the wheelset 100, increasing the contact area and reducing the pressure of the stop member 31 on the wheelset 100, thus avoiding damage to the wheelset 100.

[0082] Furthermore, the rotation angle of the stop member 31 relative to the guide rail 1 is 80°-120°. Optionally, see [reference needed]. Figures 9 to 11The stop 31 rotates at an angle of 80° relative to the guide rail 1, which increases the stop height and prevents the moving wheel pair 100 from rolling over the stop 31, thereby improving the stopping effect of the stop 31 on the moving wheel pair 100 and ensuring the smooth progress of subsequent cleaning operations.

[0083] Optionally, the booster 32 is provided with a clearance groove to allow the wheelset 100 to pass through, so that the surface of the wheelset 100 is in full contact with the groove wall of the clearance groove, thereby increasing the contact area, reducing the pressure on the wheelset 100, and avoiding damage to the wheelset 100.

[0084] Furthermore, a buffer pad is provided on the surface of the stop member 31 that contacts the wheelset 100; and / or, a buffer pad is provided on the surface of the booster member 32 that contacts the wheelset 100, which can buffer the impact between the stop member 31 and / or the booster member 32 and the wheelset 100, and avoid damage to the wheelset 100.

[0085] Optionally, the first drive element 35 and the second drive element 36 can be existing hydraulic cylinders with high driving force.

[0086] Specifically, the displacement mechanism 3 also includes a third drive member 9, which is configured to drive the drive wheel 33 to rotate, so that the moving wheel pair 100 rolls between the drive wheel 33 and the driven wheel 34. The third drive member 9 can be an existing motor. The drive wheel 33 has a shaft hole, and a rotating shaft is interference-fitted into the shaft hole. The other end of the rotating shaft is connected to the third drive member 9 through a coupling. After the third drive member 9 rotates, it can drive the drive wheel 33 to rotate. The friction between the drive wheel 33 and the moving wheel pair 100 drives the moving wheel pair 100 to rotate. The moving wheel pair 100 drives the driven wheel 34 to rotate, so that the moving wheel pair 100 rolls between the drive wheel 33 and the driven wheel 34, ensuring that the cleaning mechanism 2 can fully contact the moving wheel pair 100, thereby improving the cleaning effect and cleaning efficiency.

[0087] The present invention also provides a method for cleaning train wheelsets, using the above-mentioned train wheelset cleaning device, comprising: S1: Train wheelset 100 is placed on guide rail 1 and rolls along guide rail 1 to displacement mechanism 3, where stop member 31 stops train wheelset 100; S2: High-pressure water jet is sprayed onto train wheelset 100 by nozzle, first roller brush 211 brushes the top of train wheelset 100, and second roller brush 221 brushes the bottom of train wheelset 100; S3: Drive wheel 33 rotates, causing train wheelset 100 to roll between drive wheel 33 and driven wheel 34; S4: Stop member 31 avoids train wheelset 100, and pusher member 32 pushes train wheelset 100 away from the cleaning area; S5: The next train wheelset 100 to be cleaned rolls to displacement mechanism 3, and steps S1 to S4 are repeated.

[0088] The present invention provides a method for cleaning train wheelsets, employing the aforementioned train wheelset cleaning device. A stop 31 automatically stops the train wheelset 100 to be cleaned, a cleaning mechanism 2 automatically brushes the train wheelset 100, and the driving wheel 33 and driven wheel 34 rotate the train wheelset 100, improving the cleaning effect of the cleaning mechanism 2. A pusher 32 automatically pushes the cleaned train wheelset 100. The train wheelset cleaning method provided by the present invention enables automated cleaning of train wheelsets 100, reducing the labor intensity of cleaning personnel and improving cleaning efficiency.

[0089] For example, in step S2, the third roller brush 234 assists in cleaning, ensuring that the cleaning mechanism 2 thoroughly cleans the wheelset 100, thereby improving cleaning efficiency and effectiveness. The movement trajectory of the cleaning mechanism 2 can be set via a teaching pendant. Key coordinate points are collected using a handheld teaching pendant, and these coordinate points are input into the control device, causing the cleaning mechanism 2 to clean the wheelset 100 according to the predetermined movement trajectory.

[0090] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
