Description

Technical Field

[0001] This invention relates to the field of railway locomotive technology, and in particular to a locomotive brake disc cleaning device and a locomotive brake disc cleaning method. Background Technology

[0002] The brake disc has multiple cooling ribs. Because these ribs are spaced circumferentially along one side of the brake disc, cleaning requires manual rotation of the brake disc to reach the ribs on one side. Furthermore, the various shapes of the cooling ribs, extending radially along the brake disc, prevent the cleaning mechanism from effectively cleaning all ribs, resulting in some ribs remaining uncleaned. Additionally, feathers, dirt, and oil adhere to the brake disc, further complicating the cleaning process. Summary of the Invention

[0003] The purpose of this invention is to provide a locomotive brake disc cleaning device that can effectively clean the heat dissipation fins on the brake disc, with higher efficiency and better cleaning effect.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0010] The cleaning mechanism is capable of cleaning the brake disc.

[0011] Optionally, the transport platform includes a transmission driver, a first sprocket, a first chain, and multiple rollers. The transmission driver is mounted on the frame, and its rotational output end is connected to the first sprocket. The first sprocket is meshed with the first chain. Each roller has a first tooth, and the first chain is meshed with multiple first teeth. The multiple rollers are spaced apart along the first horizontal direction and rotatably connected to the frame. The transmission driver can drive the first sprocket to rotate, which in turn drives the first chain to move. The movement of the first chain then drives the multiple rollers to rotate around their own axes.

[0012] Optionally, the gripping and flipping mechanism includes a sliding plate, a sliding driver, a second sprocket, and a second chain. The sliding driver is mounted on the frame, and its rotation output end is connected to the second sprocket. The second sprocket is meshed with the second chain, which is connected to the sliding plate. The sliding driver can drive the second sprocket to rotate, which in turn drives the second chain to move, and the movement of the second chain causes the sliding plate to slide.

[0013] Optionally, the gripping and flipping mechanism further includes a gripping driver, a bidirectional threaded rod, and two jaws. The gripping driver is disposed on the sliding plate, and the rotation output end of the gripping driver is connected to the bidirectional threaded rod. The jaws are threadedly connected to the bidirectional threaded rod and slidably connected to the sliding plate along the second horizontal direction. The gripping driver can drive the bidirectional threaded rod to rotate around its own axis. The rotation of the bidirectional threaded rod can drive the two jaws to move towards or away from each other along the second horizontal direction.

[0014] Optionally, the claw includes:

[0015] A connector is slidably disposed on the sliding plate along the second horizontal direction and connected to the output end of the gripping driver;

[0016] A flip-up driver is mounted on the connector;

[0017] A limiting clamp is disposed at the output end of the flip driver, and the flip driver can drive the limiting clamp to rotate around the second horizontal direction;

[0018] Two limiting wheels are respectively rotatably disposed at both ends of the limiting clamp, and the two limiting wheels can abut against the outer periphery of the brake disc.

[0019] Optionally, the lifting mechanism includes a lifting driver and a lifting platform. The lifting driver is mounted on the frame, and its output end is connected to the lifting platform, enabling the lifting platform to move vertically.

[0020] Optionally, the rotating mechanism includes a rotary driver, a driving gear, a driven gear, and a support platform. The rotary driver is disposed on the lifting platform, and the output end of the rotary driver is connected to the driving gear. The driving gear is meshed with the driven gear, and the support platform is connected to the driven gear. The rotary driver can drive the driving gear to rotate, and the rotation of the driving gear drives the driven gear to rotate. The rotation of the driven gear drives the support platform to rotate in the vertical direction.

[0021] Optionally, the cleaning mechanism includes a cleaning driver, a third sprocket, a third chain, a fourth sprocket, and two roller brushes. The two roller brushes are spaced apart in a vertical direction, and the roller brushes extend in a second horizontal direction and are rotatably connected to the frame. The output end of the cleaning driver is connected to the third sprocket, the third sprocket is engaged with the third chain, the third chain is engaged with the fourth sprocket, and the fourth sprocket is connected to the roller brushes. The cleaning driver can drive the third sprocket to rotate, the rotation of the third sprocket drives the third chain to move, the movement of the third chain drives the fourth sprocket to rotate, and the rotation of the fourth sprocket drives the roller brushes to rotate around the second horizontal direction.

[0022] Optionally, the cleaning mechanism further includes a tensioning wheel and two pulleys. The two pulleys are connected to the two roller brushes in a one-to-one correspondence and are connected to the tensioning wheel via a synchronous belt drive. The rotation of the fourth sprocket can drive the lower roller brush to rotate, and the rotation of the lower roller brush can drive the pulley connected to it to rotate, which in turn drives the other pulley to rotate via the synchronous belt and the tensioning wheel. The rotation of the other pulley can drive the upper roller brush to rotate.

[0023] Another objective of this invention is to provide a method for cleaning locomotive brake discs, which can effectively clean the heat dissipation fins on the brake discs, with higher efficiency and better cleaning effect.

[0024] To achieve this objective, the present invention adopts the following technical solution:

[0025] A method for cleaning locomotive brake discs, using the locomotive brake disc cleaning device described above, includes the following steps:

[0026] S1. Place the brake disc on the transport platform;

[0027] S2. Determine whether the heat dissipation fins of the brake disc are facing down. If so, transport the brake disc to the cleaning mechanism via the transport table for cleaning. If not, lift the brake disc via the lifting mechanism, grab the brake disc via the grabbing and flipping mechanism, flip the brake disc so that the heat dissipation fins are facing down, place the brake disc on the transport table, and transport the flipped brake disc to the cleaning mechanism for cleaning via the transport table.

[0028] S3. After the brake disc is cleaned for the first time, the transport table reverses and transports the brake disc back to its initial position. The rotating mechanism drives the brake disc to rotate, and the transport table transports the brake disc to the cleaning mechanism for cleaning again.

[0029] S4. After the brake disc cleaning operation is completed, remove the brake disc from the transport table.

[0030] Beneficial effects:

[0031] This invention provides a locomotive brake disc cleaning device and its control method. The locomotive brake disc cleaning device includes a frame, a gripping and flipping mechanism, a rotating mechanism, a lifting mechanism, and a cleaning mechanism. The frame includes a transport platform, which drives the brake disc to move along a first horizontal direction and then transports it to the cleaning mechanism for cleaning. The gripping and flipping mechanism is slidably mounted on the frame in a vertical direction, capable of gripping and flipping the brake disc. The vertical sliding of the gripping and flipping mechanism facilitates gripping the raised brake disc, and flipping the brake disc ensures that the cooling fins face downwards, facilitating cleaning of the cooling fins. Since the cooling fins are radially arranged on one side of the brake disc, the rotating mechanism drives the brake disc to rotate 90 degrees around the vertical direction, allowing the cleaning mechanism to better clean the cooling fins on one side. The transport platform has a disc passage opening. The lifting mechanism drives the rotating mechanism and the brake disc to move vertically and extend from the disc passage opening, thereby preventing interference between the brake disc and the transport platform during lifting, rotating, gripping, and flipping, ensuring operational safety. The cleaning mechanism can clean the brake discs more efficiently and effectively. The control method of the locomotive brake disc cleaning device uses the aforementioned locomotive brake disc cleaning device. With the above-mentioned configuration, the locomotive brake disc cleaning device of this application can effectively clean the heat dissipation fins on the brake discs, achieving higher efficiency and better cleaning results.

[0051] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0052] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0053] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0054] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0055] like Figures 1-12As shown, this embodiment provides a locomotive brake disc cleaning device, which includes a frame 1, a gripping and flipping mechanism 2, a rotating mechanism 3, a lifting mechanism 4, and a cleaning mechanism 5. The frame 1 includes a transport platform 11, which can drive the brake disc 100 to move in a first horizontal direction. The gripping and flipping mechanism 2 is slidably disposed on the frame 1 in a vertical direction and can grip and flip the brake disc 100. The rotating mechanism 3 can drive the brake disc 100 to rotate around a vertical direction. The transport platform 11 is provided with a disc opening 111. The lifting mechanism 4 can drive the rotating mechanism 3 and the brake disc 100 to move in a vertical direction and extend out from the disc opening 111. The cleaning mechanism 5 can clean the brake disc 100.

[0056] In this embodiment, the frame 1 includes a transport platform 11, which drives the brake disc 100 to move along a first horizontal direction and then transport it to the cleaning mechanism 5 for cleaning. A gripping and flipping mechanism 2 is slidably mounted on the frame 1 in a vertical direction, capable of gripping and flipping the brake disc 100. The vertical sliding of the gripping and flipping mechanism 2 facilitates gripping the lifted brake disc 100. Simultaneously, flipping the brake disc 100 ensures that the heat dissipation fins of the brake disc 100 are placed downwards, facilitating cleaning of the heat dissipation fins. Since the heat dissipation fins are radially arranged on one side of the brake disc 100, the rotating mechanism 3 can drive the brake disc 100 to rotate 90 degrees around the vertical direction, allowing the cleaning mechanism 5 to better clean the heat dissipation fins on one side. The transport platform 11 is equipped with a through-hole 111. The lifting mechanism 4 can drive the rotating mechanism 3 and the brake disc 100 to move vertically and extend from the through-hole 111, thereby preventing the brake disc 100 from interfering with the transport platform 11 during lifting, rotating, grabbing, and flipping, ensuring operational safety. The cleaning mechanism 5 can clean the brake disc 100 with higher efficiency and better cleaning effect. With the above settings, the locomotive brake disc cleaning device of this embodiment can effectively clean the heat dissipation fins on the brake disc 100 with higher efficiency and better cleaning effect.

[0057] Specifically, such as Figure 1 and Figure 2As shown, the transport table 11 includes a transmission driver 112, a first sprocket 113, a first chain, and multiple rollers 114. The transmission driver 112 is mounted on the frame 1, and its rotational output end is connected to the first sprocket 113. The first sprocket 113 is meshed with the first chain (not shown in the figure). The rollers 114 are provided with first teeth 1141, and the first chain is meshed with multiple first teeth 1141. The multiple rollers 114 are spaced apart along a first horizontal direction and rotatably connected to the frame 1. By increasing the contact area between the rollers 114 and the brake disc 100, the brake disc 100 can be more stable during transport on the transport table 11. The transmission driver 112 can drive the first sprocket 113 to rotate. The rotation of the first sprocket 113 drives the first chain to move, and the movement of the first chain drives the multiple rollers 114 to rotate around their own axes, thereby transporting the brake disc 100 along the first horizontal direction to the cleaning mechanism 5 for cleaning. Furthermore, the transmission driver 112 in this embodiment adopts a servo motor, stepper motor or other structure to improve the transmission efficiency and accuracy between the above components.

[0058] More specifically, such as Figure 7 and Figure 8 As shown, the two ends of the through-hole 111 are provided with partitions, and the roller shaft 114 includes a long roller and a short roller. The long roller is rotatably mounted on the frame 1 to drive the brake disc 100 for transport and transmission. The short roller is rotatably mounted between the partition and the frame 1 to leave space for the through-hole 111, so that the brake disc 100 can extend from the through-hole 111 for lifting, gripping and flipping operations, etc.

[0059] Specifically, such as Figure 1 and Figure 3 As shown, the gripping and flipping mechanism 2 includes a sliding plate 21, a sliding driver 23, a second sprocket 24, and a second chain (not shown in the figure). The sliding driver 23 is mounted on the frame 1, and its rotation output end is connected to the second sprocket 24. The second sprocket 24 is meshed with the second chain, which is connected to the sliding plate 21. The sliding driver 23 can drive the second sprocket 24 to rotate, which in turn drives the second chain to move. The movement of the second chain causes the sliding plate 21 to slide, thereby enabling the sliding plate 21 to slide vertically relative to the frame 1, thus facilitating the gripping and flipping mechanism 2 to grip and flip the brake disc 100. Furthermore, the sliding driver 23 includes a servo motor, a coupling, and a rotating shaft. The servo motor is connected to the rotating shaft via the coupling, and the rotating shaft is connected to the second sprocket 24. The servo motor drives the rotating shaft to rotate, which in turn drives the second sprocket 24 to rotate around its own axis. This not only ensures efficient and convenient transmission of the above components but also reduces the risk of failure during transmission by using a coupling, making the operation safer and more efficient.

[0060] More specifically, each end of the frame 1 is equipped with a second sprocket 24, and there are two second chains. The two second sprockets 24 are meshed with the two second chains in a one-to-one correspondence. The two second sprockets 24 drive the two second chains to move. The two chains are respectively connected to the two ends of the sliding plate 21, thereby driving the sliding plate 21 to move in the vertical direction, ensuring that the movement of the sliding plate 21 is more stable and smooth. The frame 1 is equipped with a slide rail extending in the vertical direction, and the sliding plate 21 is equipped with a slider. The slider is slidably connected to the slide rail, thereby guiding the sliding direction of the sliding plate 21 and ensuring that the sliding plate 21 is more stable during operation.

[0061] Specifically, such as Figure 5 and Figure 6 As shown, the gripping and flipping mechanism 2 also includes a gripping assembly 22, which is used to grip the brake disc 100. The gripping assembly 22 includes a gripping driver 221, a bidirectional threaded rod 222, and two jaws 223. The gripping driver 221 is mounted on the sliding plate 21. The rotation output end of the gripping driver 221 is connected to the bidirectional threaded rod 222. The jaws 223 are threaded to the bidirectional threaded rod 222 and slidably connected to the sliding plate 21 along the second horizontal direction. The gripping driver 221 can drive the bidirectional threaded rod 222 to rotate around its own axis. The rotation of the bidirectional threaded rod 222 can drive the two jaws 223 to move towards or away from each other along the second horizontal direction, thereby gripping the brake disc 100. Moreover, it can adapt to gripping brake discs 100 with different outer diameters, making it more adaptable. When the two jaws 223 move towards each other, they can grip the brake disc 100. When the two jaws 223 move away from each other, the brake disc 100 can disengage from the jaws 223 for subsequent cleaning operations. Furthermore, the gripping driver 221 includes a servo motor and a coupling. The servo motor is connected to the bidirectional threaded rod 222 via the coupling, which reduces the occurrence of malfunctions, ensures efficient and convenient transmission, and guarantees operational safety.

[0062] It should be noted that in this embodiment, the second horizontal direction is perpendicular to the first horizontal direction to ensure that the brake disc 100 is more stable and smooth during transportation, cleaning, and other operations. In other embodiments, the first and second horizontal directions can be determined according to the actual operation, and are not limited in detail here.

[0063] More specifically, such as Figures 5-8As shown, the gripping actuator 221 is located on the side of the sliding plate 21 opposite to the through-hole 111. The sliding plate 21 has a through-hole, and the grippers 223 are located on the other side of the sliding plate 21. The two grippers 223 are screwed onto the bidirectional threaded rod 222 through the through-hole, thereby ensuring that the grippers 223 and the lifted brake disc 100 are on the same side, so that the grippers 223 can smoothly grip the brake disc 100, ensuring the rationality of the above component layout. Furthermore, the sliding plate 21 has a slide rail extending along the second horizontal direction, and the gripper has a sliding block, which is slidably connected to the slide rail to ensure that the two grippers 223 can slide smoothly along the second horizontal direction, playing a guiding role.

[0064] More specifically, such as Figure 7 and Figure 8 As shown, the gripper 223 includes a connector 2231, a flipping driver 2232, a limiting clamp 2233, and a limiting wheel 2234. The connector 2231 is slidably disposed on the sliding plate 21 along the second horizontal direction and is connected to the output end of the gripping driver 221. The gripping driver 221 drives the bidirectional threaded rod 222 to rotate, thereby driving the two connectors 2231 to move towards each other or away from each other along the second horizontal direction. A flip drive 2232 is mounted on a connector 2231, and a limiting clamp 2233 is mounted on the output end of the flip drive 2232. The flip drive 2232 can drive the limiting clamp 2233 to rotate around a second horizontal direction. When the two connectors 2231 move towards each other, they can drive the two limiting clamps 2233 to move towards each other, thereby gripping the brake disc 100. When the limiting clamp 2233 rotates, it can drive the brake disc 100 it grips to rotate together around the second horizontal direction, thereby flipping the brake disc 100 180 degrees so that the heat dissipation fins face downwards, facilitating cleaning operations. Two limiting wheels 2234 are provided, and the two limiting wheels 2234 are respectively rotatably mounted at both ends of the limiting clamp 2233. The two limiting wheels 2234 can abut against the outer periphery of the brake disc 100, thereby firmly limiting the brake disc 100 in the limiting clamp 2233 and preventing it from shaking, thus preventing the brake disc 100 from detaching from the limiting clamp 2233. Furthermore, the flip driver 2232 in this embodiment can adopt other specific structures such as a servo motor or a stepper motor to ensure efficient and accurate transmission of the above components, without further limitations. Even further, a sliding block is disposed on the connector 2231, and by sliding the sliding block in the slide rail, the connector 2231 is driven to slide relative to the sliding plate 21 in the second horizontal direction.

[0065] Specifically, such as Figure 1 , Figure 4 , Figure 9 and Figure 10As shown, the lifting mechanism 4 includes a lifting driver 41 and a lifting platform 42. The lifting driver 41 is mounted on the frame 1, and its output end is connected to the lifting platform 42, enabling it to drive the lifting platform 42 to move vertically. This facilitates the lifting of the brake disc 100, aiding in operations such as gripping, flipping, and cleaning. Furthermore, in this embodiment, the lifting driver 41 employs a cylinder, electric cylinder, or similar structure to ensure the stability of the lifting platform 42 during lifting; however, further limitations are not specified here. Moreover, rack and pinion synchronous lifters are provided at the four corners of the bottom of the lifting platform 42 to ensure its stability during lifting, making operations safer. Furthermore, by providing rack and pinion synchronous lifters, the lifting platform 42 can withstand larger loads, improving synchronization and further enhancing safety performance. In addition, those skilled in the art understand the specific working principle of the rack and pinion synchronous lifter, which will not be elaborated upon here.

[0066] Specifically, such as Figure 9 and Figure 10 As shown, the rotating mechanism 3 includes a rotating driver 31, a driving gear 32, a driven gear 33, and a support platform 34. The rotating driver 31 is mounted on a lifting platform 42. The lifting platform 42 raises and lowers the rotating mechanism 3 and its brake disc 100, allowing the brake disc 100 to rotate. The output end of the rotating driver 31 is connected to the driving gear 32, which meshes with the driven gear 33. The support platform 34 is connected to the driven gear 33. The rotating driver 31 drives the driving gear 32 to rotate, which in turn drives the driven gear 33 to rotate. The driven gear 33 then drives the support platform 34 to rotate vertically, thereby rotating the brake disc 100 on the support platform 34. By adjusting the rotation angle of the brake disc 100 in the vertical direction, the cleaning mechanism 5 can clean the cooling fins on the underside of the brake disc 100. This configuration efficiently transmits power, ensuring the stable rotation of the support platform 34. Furthermore, the meshing of the driving gear 32 and the driven gear 33 allows the meshing point to withstand a higher load, thereby extending the service life of the rotary actuator 31. Further, precise control of the rotation angle of the support platform 34 is achieved by controlling the current, voltage, or computer program, thus assisting in the precise rotation of the brake disc 100. Moreover, in this embodiment, the rotary actuator 31 can employ other specific structures such as a servo motor or a stepper motor to ensure efficient and precise transmission of the aforementioned components; no further limitations are imposed here.

[0067] Specifically, such as Figures 5-12As shown, the cleaning mechanism 5 includes a cleaning drive 51, a third sprocket 52, a third chain (not shown), a fourth sprocket 53, and two roller brushes 54. The two roller brushes 54 are arranged vertically at intervals to allow the brake disc 100 to pass between them for cleaning. The roller brushes 54 extend in a second horizontal direction and are rotatably connected to the frame 1 to ensure sufficient contact between the roller brushes 54 and the surface of the brake disc 100, thereby improving the cleaning quality. Figure 11 As shown, the output end of the cleaning driver 51 is connected to the third sprocket 52, which is meshed with the third chain. The third chain is meshed with the fourth sprocket 53, which is connected to the roller brush 54. The cleaning driver 51 can drive the third sprocket 52 to rotate. The rotation of the third sprocket 52 drives the third chain to move, which in turn drives the fourth sprocket 53 to rotate. The rotation of the fourth sprocket 53 drives the roller brush 54 to rotate around the second horizontal direction, thereby transmitting the driving force of the cleaning driver 51 to the roller brush 54. The rotation of the roller brush 54 then performs the cleaning operation on the brake disc 100. This configuration ensures the stability of the transmission connections between the components, improves the cleaning effect, and makes the operation safer. Furthermore, the cleaning driver 51 in this embodiment can adopt other specific structures such as a servo motor or a stepper motor to ensure efficient and precise transmission of the above components; no further limitations are imposed here.

[0068] More specifically, such as Figure 5 As shown, the roller brush 54 includes a brush shaft and brush bristles. Both ends of the brush shaft are rotatably connected to the frame 1 via flange-type safety chucks. The flange-type safety chucks connect the brush shaft to the roller brush for better torque transmission, ensuring the roller brush 54 rotates safely and smoothly. The brush bristles are spirally coiled around the outer circumference of the brush shaft in a second horizontal direction to increase the contact area between the roller brush 54 and the brake disc 100, thereby improving cleaning quality.

[0069] Specifically, such as Figure 12As shown, the roller brush 54 is height-adjustably mounted on the frame 1, allowing for adjustable spacing between the two roller brushes 54. This adapts to cleaning operations of brake discs 100 of different specifications, while also reducing wear on the roller brush 54 during cleaning, ensuring cleaning effectiveness and extending the service life of the cleaning mechanism 5. Furthermore, the roller brush 54 has sliding plates and fasteners at both ends. The sliding plates are clamped between the fasteners and the flange-type safety chuck. The frame 1 has a vertically extending groove, in which the sliding plates slide, allowing the roller brush 54 to slide up and down, adjusting its height. Even further, the frame 1 includes a wall panel and two L-shaped pressure plates connected to the wall panel, forming a groove between them. Bolts can be used to screw the L-shaped pressure plates onto the wall panel. Since the thickness of the sliding plate is less than the depth of the groove, tightening the bolts locks the sliding plate into the groove, thus fixing the position of the roller brush 54 for smooth cleaning operations. Furthermore, to further ensure the locking effect of the slide plate, the lower end of the slide plate is detachably connected to the wall panel via a set screw, ensuring that the height of the roller brush 54 can be fixed. Additionally, as... Figure 12 As shown, in order to ensure that the transmission of each component proceeds normally during the height adjustment of the roller brush 54, the cleaning driver 51 is connected to the slide plate of the lower roller brush 54, and thus adjusts the height synchronously with the lower roller brush 54.

[0070] More specifically, such as Figure 12 As shown, the cleaning mechanism 5 also includes a tensioning pulley 55 and two pulleys 56. The two pulleys 56 are connected one-to-one to the two roller brushes 54 and are connected to the tensioning pulley 55 via a synchronous belt (not shown). The rotation of the fourth sprocket 53 drives the lower roller brush 54 to rotate, which in turn drives the connected pulley 56 to rotate. This, in turn, drives the other pulley 56 to rotate via the synchronous belt and tensioning pulley 55. The rotation of the other pulley 56 drives the upper roller brush 54 to rotate, allowing both roller brushes 54 to rotate simultaneously, thus thoroughly cleaning the brake disc 100. Simultaneously, the tensioning pulley 55 and synchronous belt ensure that the rotational movements of the pulleys 56 remain synchronized. Furthermore, in this embodiment, the tensioning pulley 55 is slidably mounted on the frame 1 along the first horizontal direction to adjust the tension of the synchronous belt, ensuring more stable transmission and safer operation of the aforementioned components. Furthermore, as... Figure 11 As shown, the pulley 56 connected to the upper roller brush 54 and the fourth sprocket 53 are coaxially arranged facing each other to ensure that the rotation of the fourth sprocket 53 can smoothly drive the pulley 56 to rotate around the second horizontal direction, thereby driving the upper roller brush 54 to rotate around the second horizontal direction together with the lower roller brush 54, so as to achieve cleaning of the brake disc 100.

[0071] This embodiment also provides a method for cleaning locomotive brake discs. Using the locomotive brake disc cleaning device of this embodiment to clean the brake disc 100 can effectively clean the cooling fins on the brake disc 100, resulting in higher efficiency and better cleaning effect. The method includes the following specific steps:

[0072] S1. Place the brake disc 100 on the transport table 11.

[0073] In step S1 above, the operator uses a KBK crane (KBK flexible crane) to lift the brake disc 100 onto the transport platform 11, so that the brake disc 100 and the platform surface of the bearing platform 34 face each other, which facilitates subsequent lifting and rotation.

[0074] S2. Determine whether the heat dissipation fins of the brake disc 100 are facing downwards. If so, transport the brake disc 100 to the cleaning mechanism 5 via the transport table 11 for cleaning. If not, lift the brake disc 100 via the lifting mechanism 4, grab the brake disc 100 via the grabbing and flipping mechanism 2, flip the brake disc 100 so that the heat dissipation fins are facing downwards, place the brake disc 100 on the transport table 11, and transport the flipped brake disc 100 to the cleaning mechanism 5 via the transport table 11 for cleaning.

[0075] In step S2 above, the specific orientation of the heat dissipation fins on the brake disc 100 is determined by the operator's visual observation or by a vision mechanism (such as an image processing system, computer vision library, etc.). If the heat dissipation fins are determined to be downward, the transmission driver 112 directly drives multiple rollers 114 to rotate, thereby causing the brake disc 100 to move along the first horizontal direction. The cleaning driver 51 drives the roller brush 54 to rotate around the second horizontal direction. When the brake disc 100 passes two roller brushes 54, the first cleaning operation is completed. Conversely, if the heat dissipation fins are determined to be upward, the lifting driver 41 drives the lifting platform 42 to rise. The rise of the lifting platform 42 causes the support platform 34 to extend from the disc opening 111 and support and lift the brake disc 100. After the brake disc 100 is raised to a suitable position, the sliding driver 23 drives the sliding plate 21 to descend and gradually approach the brake disc 100 until the height of the brake disc 100 is within the limit clamp 2. When the heights of 233 are consistent, the gripping driver 221 drives the two grippers 223 to move towards each other, thereby gripping the brake disc 100 through the limit clamp 2233 and the limit wheel 2234. After the gripping operation, in order to have sufficient space to flip the brake disc 100, the sliding driver 23 will drive the sliding plate 21 to rise, causing the brake disc 100 to move upward. At this time, the flipping driver 2232 drives the limit clamp 2233 to rotate 180 degrees around the second horizontal direction, thereby flipping the heat dissipation fins of the brake disc 100 downward. After the brake disc 100 is flipped, the sliding driver 23 drives the sliding plate 21 to descend again, so that the brake disc 100 is placed back on the support platform 34 (at this time, the heat dissipation fins are downward). The lifting driver 41 drives the lifting platform 42 to descend until the multiple rollers 114 on the transport platform 11 come into contact with the brake disc and transport the brake disc 100 to the cleaning mechanism 5 for cleaning.

[0076] S3. After the brake disc 100 is cleaned for the first time, the transport table 11 reverses the flow and transports the brake disc 100 back to its initial position. The rotating mechanism 3 drives the brake disc 100 to rotate, and the transport table 11 transports the brake disc 100 to the cleaning mechanism 5 for cleaning again.

[0077] In step S3 above, due to the unique arrangement of the heat dissipation fins, the cleaning mechanism 5 can only clean part of the heat dissipation fins. Therefore, after the first cleaning operation, the transmission driver 112 will drive multiple rollers 114 to rotate in the opposite direction, thereby conveying the brake disc 100 to the initial position on the transport table 11. At this time, the lifting driver 41 drives the lifting table 42 to rise, driving the brake disc 100 on the rotating mechanism 3 and the bearing table 34 to rise together and extend from the disc opening 111 to avoid the transport table 11 interfering with the rotation of the brake disc 100. The rotating driver 31 drives the bearing table 34 to rotate, thereby driving the brake disc 100 to rotate 90 degrees around the vertical direction. At this time, the lifting driver 41 drives the lifting table 42 to descend, causing the brake disc 100 to fall back onto the surface of the rollers 114. The transmission driver 112 drives multiple rollers 114 to rotate, so that the rotated brake disc 100 is cleaned again by the cleaning mechanism 5. Thus, the pre-treatment cleaning operation of the brake disc 100 is completed.

[0078] S4. After the cleaning of the brake disc 100 is completed, remove the brake disc 100 from the transport table 11.

[0079] In step S4 above, the operator can again use the KBK crane to lift the brake disc 100 off the transport platform 11 to improve work efficiency. Furthermore, the lifting method in this embodiment is not limited; those skilled in the art can make appropriate improvements based on the above technical solution, which will not be elaborated further here.

[0080] 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 will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
