Description

Technical Field

[0001] This utility model relates to the field of wheelset cleaning technology, and in particular to a power train wheelset gearbox cleaning device. 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 mainly relies on manual labor. Cleaning personnel use high-pressure water guns, brushes, and other tools to clean each component of the wheelset one by one. This cleaning method is labor-intensive, requiring cleaning personnel to work in relatively confined spaces such as train maintenance pits. Cleaning the bottom of the wheelsets requires prolonged bending and stooping, which can easily lead to physical fatigue. Furthermore, manual cleaning is inefficient, with each set of wheelsets taking a long time to clean, making it difficult to meet the needs of high-density railway vehicle maintenance. Additionally, the quality of manual cleaning is greatly affected by the operator's experience, easily resulting in incomplete cleaning, missed areas, and poor cleaning results. Utility Model Content

[0014] The aforementioned power train wheelset gearbox cleaning device further includes a fifth driving member configured to drive the driving wheel to rotate, so that the power train wheelset rolls between the driving wheel and the driven wheel.

[0015] In the aforementioned power train wheelset gearbox cleaning device, the stop block includes an arc-shaped groove that can fit against the surface of the power train wheelset.

[0016] In the aforementioned power train wheelset gearbox cleaning device, a buffer pad is provided on the surface of the stop block that contacts the power train wheelset; and / or, a buffer pad is provided on the surface of the booster block that contacts the power train wheelset.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] The power train wheelset gearbox cleaning device provided by this utility model can clean power train wheelsets, reduce the workload of workers, and improve the cleaning effect and efficiency of power train wheelsets.

[0040] like Figures 1-6 As shown, the power train wheelset gearbox cleaning device includes a guide rail 1, a stop assembly 2, and a cleaning mechanism 3. The guide rail 1 is configured to hold the power train wheelset 100. The stop assembly 2 includes a first drive member 21, a stop block 22, a second drive member 23, and an assist block 24. One end of the stop block 22 is throttle-connected to the first drive member 21, and the other end is rotatably connected to the guide rail 1. The first drive member 21 can drive the stop block 22 away from the guide rail 1 to rotate and stop the power train wheelset 100, or the first drive member 21 can drive the stop block 22 closer to the guide rail 1 to rotate and avoid the power train wheelset 100. The second drive member 23 and the assist block 24... One end of the force block 24 is connected to the transmission, and the other end of the assist block 24 is rotatably connected to the guide rail 1. The second drive member 23 can drive the assist block 24 to rotate away from the guide rail 1 to push the wheelset 100. The cleaning mechanism 3 includes a lifting component 31, a moving component 32, a third drive member 33 and a cleaning brush 34. The lifting component 31 can drive the moving component 32 to move up and down in the vertical direction. The moving component 32 can drive the third drive member 33 and the cleaning brush 34 to reciprocate along the length of the guide rail 1. The third drive member 33 is configured to drive the cleaning brush 34 to rotate to brush the bottom of the wheelset 100.

[0041] The gearbox cleaning device for power train wheelsets provided by this utility model includes a guide rail 1, on which the power train wheelset 100 can roll for easy cleaning. The cleaning mechanism 3 includes a lifting component 31, a moving component 32, a third drive component 33, and a cleaning brush 34. During cleaning, the lifting component 31 drives the moving component 32 to move vertically, and the moving component 32 drives the cleaning brush 34 to move along the length of the guide rail 1. Therefore, the cleaning brush 34 can reciprocate vertically and along the length of the guide rail 1, increasing the brushing area of ​​the power train wheelset 100 and improving the cleaning effect. Simultaneously, the stop block 22 of the stop component 2 can stop the power train wheelset 100, ensuring that the cleaning brush 34 cleans the power train wheelset 100 and improving the cleaning effect. After cleaning the power train wheelset 100, the assist block 24 can push the power train wheelset 100 away from the cleaning position, allowing the next power train wheelset 100 to roll into the cleaning position for the cleaning mechanism 3 to clean, thus improving cleaning efficiency. The power train wheelset gearbox cleaning device provided by this utility model can improve the cleaning effect and cleaning efficiency of the power train wheelset 100.

[0042] This embodiment does not specifically limit the shape of the guide rail 1. For example, see [link to example]. Figure 1The 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.

[0043] The lifting assembly 31 is used to drive the cleaning brush 34 to rise and fall. In this embodiment, see [reference needed]. Figures 1 to 3 The lifting assembly 31 includes four support columns 311, which extend vertically and are arranged in a rectangular shape. Each support column 311 is provided with a telescopic member 312. The ends of the four telescopic members 312 away from the support columns 311 are fixedly connected to the moving assembly 32. When the telescopic member 312 extends, it causes the moving assembly 32 to rise. When the telescopic member 312 shortens, it causes the moving assembly 32 to fall.

[0044] Specifically, the support column 311 is a rectangular column, which is easy to process. Adjacent support columns 311 are connected by a reinforcing strip 313, which extends horizontally. The reinforcing strip 313 makes the four support columns 311 form a rigid whole, improving the support stability of the support columns 311.

[0045] Furthermore, a support base is fixedly connected to the bottom end of the support column 311. The area of ​​the support base is larger than the cross-sectional area of ​​the support column 311, which increases the contact area between the support column 311 and the ground, thereby further improving the stability of the support.

[0046] Optionally, the telescopic component 312 can be an electric push rod, a pneumatic cylinder, or a hydraulic cylinder, which is readily available.

[0047] Specifically, the moving component 32 includes a support plate 321, a fourth driving member 322, a driving screw 323, a driving nut 324, and a moving plate 325. The support plate 321 is fixedly connected to the telescopic member 312, the fourth driving member 322 is fixedly connected to the support plate 321, the driving screw 323 is driven by the fourth driving member 322, the driving nut 324 is screwed to the driving screw 323, and the driving nut 324 is fixedly connected to the moving plate 325. The third driving member 33 and the cleaning brush 34 are disposed on the top surface of the moving plate 325. The screw and nut transmission is stable, improving the movement stability of the moving plate 325.

[0048] When in use, the fourth drive component 322 works to rotate the drive screw, the drive nut 324 moves along the axial direction of the drive screw 323, the moving plate 325 moves with the drive nut 324, and thus drives the third drive component 33 and the cleaning brush 34 on the moving plate 325 to move.

[0049] Optionally, both the third drive unit 33 and the fourth drive unit 322 are existing motors, which are readily available and easy to use.

[0050] Specifically, see Figure 1 The cleaning mechanism 3 also includes a rotating shaft 4, which is connected to the third drive member 33. The cleaning brush 34 is fixedly connected to the rotating shaft 4 along the circumference of the rotating shaft 4. The third drive member 33 can drive the rotating shaft 4 to rotate, thereby causing the cleaning brush 34 on the rotating shaft 4 to rotate and drive the roller wheels 100.

[0051] It should be noted that, in order to ensure that the cleaning brush 34 can move along the length of the guide rail 1, the end of the rotating shaft 4 away from the third driving component 33 can be suspended or slidably connected to the guide rail 1 to improve stability.

[0052] To further improve the cleaning effect of the train wheelset 100, in this embodiment, the train wheelset gearbox cleaning device also includes a driving wheel 5 and a driven wheel 6. The driving wheel 5 and the driven wheel 6 are rotatably connected on each guide rail 1. The driving wheel 5 and the driven wheel 6 are spaced apart along the length of the guide rail 1. The train wheelset 100 can roll on the driving wheel 5 and the driven wheel 6, so that the cleaning brush 34 can clean the train wheelset 100 more thoroughly.

[0053] Specifically, the gearbox cleaning device for the motor wheelset also includes a fifth drive member 7, which is configured to drive the drive wheel 5 to rotate so that the motor wheelset 100 rolls between the drive wheel 5 and the driven wheel 6.

[0054] Specifically, the fifth drive component 7 can be an existing motor. The drive wheel 5 has a shaft hole with an interference fit inside the shaft hole. The other end of the shaft is connected to the fifth drive component 7 via a coupling. When the fifth drive component 7 rotates, it can drive the drive wheel 5 to rotate. The friction between the drive wheel 5 and the drive wheel pair 100 causes the drive wheel pair 100 to rotate. The drive wheel pair 100 drives the driven wheel 6 to rotate, so that the drive wheel pair 100 rolls between the drive wheel and the driven wheel 6, ensuring that the cleaning brush 34 can fully contact the drive wheel pair 100, thereby improving the cleaning effect and cleaning efficiency.

[0055] In this embodiment, the stop block 22 includes an arc-shaped groove that can fit against the surface of the train wheelset 100. The arc-shaped groove fits against the surface of the train wheelset 100, increasing the contact area and reducing the pressure of the stop block 22 on the train wheelset 100, thus avoiding damage to the train wheelset 100.

[0056] Furthermore, the rotation angle of the stop block 22 relative to the guide rail 1 is 80°-120°. Optionally, see [reference needed]. Figures 4 to 6 The stop block 22 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 block 22, thereby improving the stopping effect of the stop block 22 on the moving wheel pair 100 and ensuring the smooth progress of subsequent cleaning operations.

[0057] Optionally, the assist block 24 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.

[0058] Furthermore, a buffer pad is provided on the surface of the stop block 22 that contacts the wheelset 100; and / or, a buffer pad is provided on the surface of the booster block 24 that contacts the wheelset 100, which can buffer the impact between the stop block 22 and / or the booster block 24 and the wheelset 100, and avoid damage to the wheelset 100.

[0059] Alternatively, the cushioning pad can be made of rubber for easy access.

[0060] In order to support the guide rail 1, in this embodiment, the gearbox cleaning device for the power train wheelset also includes multiple support legs 8. Two support legs 8 are fixedly connected to the bottom end of each guide rail 1. The two support legs 8 are spaced apart along the length of the guide rail 1. The two support legs 8 bear the pressure of the guide rail 1 evenly, so as to avoid damage to a single support leg 8 due to excessive force, improve the support stability of the support legs 8, and ensure the smooth progress of subsequent cleaning operations.

[0061] In other embodiments, more support legs 8 may be provided on each guide rail 1 to improve the support stability of the guide rail 1.

[0062] Furthermore, each support leg 8 is fixedly connected to an anti-slip pad at its bottom. During the cleaning operation, the support leg 8 may generate lateral force due to the impact of high-pressure water flow. The anti-slip pad can increase the friction with the ground, prevent the support leg 8 from slipping, improve the support stability, and ensure the smooth progress of the cleaning operation.

[0063] Alternatively, the anti-slip mat can be made of nitrile rubber, which has a high coefficient of friction and can maintain stable anti-slip performance in humid environments.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
