Description

Technical Field

[0001] This application relates to the technical field of brake maintenance equipment, and in particular to a brake auxiliary cleaning mechanism. Background Technology

[0002] The yaw system is part of the wind turbine nacelle and is mainly used to align the fan blades with the wind direction. One component of the yaw system is the yaw brake, which mainly consists of a brake disc and a brake caliper. The friction between the brake caliper and the brake disc brakes the rotation of the brake disc.

[0003] However, during the use of yaw brakes, the friction pads of the brake caliper are prone to accumulating oil and dirt, which forms a glaze layer on the surface of the friction pads after a period of time, thus affecting the braking performance of the brake. Therefore, it is necessary to clean the friction pads regularly. The conventional method for cleaning friction pads is to disassemble the brake caliper and then polish the surface of the friction pads. Due to the long disassembly cycle, this results in a heavy workload for the workers. Summary of the Invention

[0004] To facilitate the fixing and installation of the scraper, this application provides a brake-assisted cleaning mechanism.

[0005] The brake auxiliary cleaning mechanism provided in this application adopts the following technical solution:

[0006] A brake auxiliary cleaning mechanism includes a cleaning pad and a fixing component. The cleaning pad is fitted onto the brake disc of the brake, and the side of the cleaning pad facing away from the brake disc is provided with protrusions, which are diamond particles. The fixing component is mounted on the brake disc and is used to fix the relative position between the cleaning pad and the brake disc. When the brake disc rotates, it can drive the protrusions on the cleaning pad to rub against the friction pad of the brake caliper.

[0007] By adopting the above technical solution, the cleaning pad is fixedly connected to the brake disc using a fixing component. When the brake disc rotates, it drives the cleaning pad to rotate as well. During the rotation of the cleaning pad, it passes through the brake caliper, and the protrusions on the cleaning pad can break and scrape away the enamel layer on the surface of the friction pad, thus cleaning the friction pad. This allows workers to clean the friction pad without disassembling the brake caliper, thereby reducing the workload of the users.

[0008] Optionally, the fixing assembly includes a fixing seat and a clamping member. The fixing seat includes a connector and two mounting plates. The two mounting plates are arranged parallel to each other on the connector. The cleaning plate is located between the two mounting plates. The clamping member is mounted on the mounting plate and is movable in a direction perpendicular to the cleaning plate.

[0009] By adopting the above technical solution, when cleaning the friction pads is required, the cleaning pads are attached to the brake disc. Then, the mounting brackets are secured to both sides of the brake disc, i.e., the brake disc is positioned between the two mounting plates. The clamping member is moved closer to the cleaning pad, thus pressing it against the cleaning pad. Simultaneously, the cleaning pad is forced against the brake disc. Under the action of friction between the cleaning pad and the brake disc, the cleaning pad is fixed to the brake disc. At this point, controlling the rotation of the brake disc will cause the cleaning pad to rotate.

[0010] Optionally, a connecting piece is provided between the two cleaning pieces, with each side of the connecting piece connected to one of the two cleaning pieces respectively. The fixing seat, the cleaning pieces, and the connecting piece form an annular structure, and the connecting piece can abut against the inner or outer wall of the brake disc.

[0011] By adopting the above technical solution, the fixing seat, the cleaning plate, and the connecting plate form a ring structure, which is then sleeved on the brake disc. At this time, the connecting plate abuts against the inner or outer wall of the brake disc, thereby limiting the cleaning plate and preventing it from rotating during the friction process between the cleaning plate and the friction plate, thus improving the stability of the cleaning plate during use.

[0012] Optionally, the fixing component includes a mounting base with an annular structure, the circumference of the brake disc passing through the interior of the mounting base, and the cleaning plate mounted on the outer wall of the mounting base.

[0013] By adopting the above technical solution, the mounting base is sleeved on the brake disc to achieve the connection between the mounting base and the brake disc, and the cleaning pad is installed on the mounting base to achieve the connection between the cleaning pad and the brake disc.

[0014] Optionally, the mounting base includes an abutment block, a baffle, and two connecting plates. The abutment block and the baffle are spaced apart, and the two connecting plates are parallel and spaced apart. The connecting plate is located between the abutment block and the baffle. The connecting plate is fixedly connected to the abutment block, and the baffle is rotatably connected to the connecting plate. Rotating the connecting plate can form an opening on one side of the mounting base, and the brake disc can be moved out from the opening.

[0015] By adopting the above technical solution, the abutment block, baffle, and connecting plate form a ring structure. The rotating baffle can create an opening on one side of the ring-shaped mounting seat. At this time, moving the mounting seat can separate the mounting seat from the brake disc, realizing a detachable connection between the cleaning plate and the brake disc, which facilitates the reuse of the auxiliary cleaning mechanism.

[0016] Optionally, the cleaning plate is slidably connected to the connecting plate in a direction perpendicular to itself.

[0017] By adopting the above technical solution, during the use of the brake, the varying thickness of oil stains on the friction pads and the different degrees of wear on the friction pads cause a certain deviation in the gap between the friction pads and the brake disc. By using a sliding cleaning pad, the vertical distance between the cleaning pad and the friction pad can be adjusted, thereby allowing the cleaning surface to better contact the friction pad and improving the cleaning effect of the cleaning pad on the friction pad.

[0018] Optionally, an adjustment assembly is provided between the cleaning plate and the mounting plate. The adjustment assembly includes an adjustment plate, which is rotatably connected to the connecting plate. A driving inclined surface is provided on the side of the adjustment plate near the cleaning plate. When the adjustment plate rotates, the driving inclined surface can drive the cleaning plate to move.

[0019] By adopting the above technical solution, rotating the adjusting plate causes the cleaning plate to move under the action of the driving inclined plane, thereby achieving the adjustment of the cleaning plate.

[0020] Optionally, the rotation axis of the adjusting plate is perpendicular to the cleaning plate, the driving inclined surface is a helical surface, the helical trajectory of the helical surface is coaxial with the rotation axis of the adjusting plate, and the cleaning plate is provided with a contact surface that fits with the driving inclined surface.

[0021] By adopting the above technical solution, during the use of the cleaning plate, a portion of the driving inclined surface comes into contact with it. Since the driving inclined surface is a spiral surface, the thickness of the adjusting plate gradually changes along the trajectory of the spiral surface. When the adjusting plate is rotated, different positions of the cleaning plate and the adjusting plate can be brought into contact, thereby moving the cleaning plate and adjusting its position. Furthermore, due to the design of the contact surface on the cleaning plate, the adjusting plate can stably adhere to the cleaning plate, supporting it and reducing the bending phenomenon caused by the frictional pressure after the cleaning plate contacts the friction plate, further improving the stability of the cleaning plate during use.

[0022] Optionally, the adjustment component further includes a sliding bar, the length direction of which extends along the spiral trajectory line of the driving inclined surface. The sliding bar is connected to the cleaning plate or the adjustment plate, and the adjustment plate or the cleaning plate has a sliding groove. The sliding bar is snapped into the sliding groove and can slide along its own length direction.

[0023] By adopting the above technical solution, the sliding strip is engaged within the sliding groove to achieve a connection between the adjusting plate and the cleaning plate. This prevents the cleaning plate from detaching from the connecting plate, improving the stability of the cleaning plate during use.

[0024] Optionally, the mounting base is provided with a drive assembly, which includes a drive gear and a worm gear assembly. The drive gear is rotatably connected to the mounting base. The adjusting plate has multiple toothed grooves around its own rotation axis. The drive gear meshes with the toothed grooves. The worm gear assembly is connected to the drive gear and is used to drive the drive gear to rotate.

[0025] By adopting the above technical solution, the worm gear assembly drives the drive gear to rotate, which in turn drives the adjusting plate meshing with the drive gear to rotate, thereby achieving adjustment of the cleaning plate. Simultaneously, due to the self-locking property of the worm gear assembly, the adjusting plate is prevented from rotating directly, thus preventing the cleaning plate from easily moving under pressure, further improving the stability of the cleaning plate during use.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Fix the cleaning plate on the brake disc. As the brake disc rotates, it drives the cleaning plate to grind against the friction plate, thereby cleaning the friction plate and reducing the workload of the workers.

[0028] 2. The two cleaning plates enable the auxiliary cleaning mechanism to simultaneously polish the friction plates on both sides of the brake disc, improving cleaning efficiency.

[0029] 3. By rotating the adjusting plate, the cleaning plate can be moved in a direction perpendicular to the brake disc under the action of the driving inclined plane, thereby adapting to the cleaning of friction plates of different thicknesses and expanding the application range of friction plates.

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] Reference Figure 1 The yaw brake includes a brake disc 1, a connecting ring 11, and a brake caliper 12. Both the brake disc 1 and the connecting ring 11 are annular structures. The connecting ring 11 is sleeved and welded to the outside of the brake disc 1. The connecting ring 11 is used to connect a rotating shaft. Weight-reducing holes are provided on the connecting ring 11 to reduce the overall weight of the brake disc 1. The brake caliper 12 is located inside the brake disc 1 and includes two friction pads 13, which are respectively disposed on both sides of the brake disc 1 and are movable towards the brake disc 1. The following description refers to the yaw brake of wind turbine equipment. Of course, the auxiliary cleaning mechanism in this application can also be applied to other structures similar to the yaw brake, such as brakes for automobile wheel hubs.

[0038] This application discloses a brake auxiliary cleaning mechanism.

[0039] Example 1

[0040] Reference Figure 1 A brake auxiliary cleaning mechanism includes a cleaning plate 2 and a fixing assembly 3. Two cleaning plates 2 are provided, respectively disposed on both sides of the brake disc 1. The cleaning plate 2 has a rectangular sheet structure, with its length direction arranged radially along the brake disc 1, and the cleaning plate 2 is in contact with the brake disc 1. The fixing assembly 3 is used to fix the two cleaning plates 2, so that when the brake disc 1 rotates, it can drive the cleaning plates 2 to rotate. During rotation, the cleaning plates 2 can contact the friction pads 13 on the brake caliper, and the friction between the cleaning plates 2 and the friction pads 13 can polish and clean the oil stains on the friction pads 13.

[0041] Reference Figure 1The fixing component 3 includes a fixing seat 31 and a clamping member 32. The fixing seat 31 includes a connecting member 311 and two mounting plates 312. The connecting member 311 passes through a weight-reducing hole. The two mounting plates 312 are arranged parallel and spaced apart on the side of the connecting member 311 near the brake disc 1 and are welded to the connecting member 311. Two cleaning pieces 2 are located between the two mounting plates 312. The clamping member 32 is mounted on one of the mounting plates 312 and is used to apply a force to the cleaning pieces 2 in a direction perpendicular to the direction of the cleaning pieces 2 and towards the brake disc 1. In this embodiment, the clamping member 32 is a screw. A threaded hole is opened on the mounting plate 312 at the position corresponding to the clamping member 32, and the screw is threaded into the threaded hole. By rotating the screw, the end of the screw near the brake disc 1 can clamp the cleaning piece 2 under the action of the thread. Under the action of friction between the clamping member 32 and the cleaning piece 2, between the mounting plate 312 and the cleaning piece 2, and between the cleaning piece 2 and the brake disc 1, the fixed connection between the cleaning piece 2 and the brake disc 1 is achieved.

[0042] Reference Figure 1 The cleaning plate 2 has multiple protrusions (not shown in the figure) on its side away from the brake disc 1. In this embodiment, the protrusions are formed by electroplating diamond particles onto the cleaning plate 2. When the brake disc 1 rotates, it drives the cleaning plate 2 to rotate. When the cleaning plate 2 passes the friction plate 13, the diamond particles scrape across the surface of the friction plate 13, thereby polishing and cleaning the oil stains on the surface of the friction plate 13. Moreover, since the diamond is granular, it can more easily break down and polish the enamel layer formed by oil stains when it scrapes across the enamel layer on the friction plate 13.

[0043] The implementation principle of the brake auxiliary cleaning mechanism in this application embodiment is as follows: When it is necessary to fix the cleaning pads 2, the two cleaning pads 2 are placed on both sides of the brake disc 1 respectively. Then, the position of the fixing component 3 is adjusted so that the mounting plate 312 and the baffle 333 are respectively located on the side away from each other of the two cleaning pads 2. Finally, the clamping member 32 is rotated so that the clamping member 32 abuts against the cleaning pads 2, thereby simultaneously fixing the two cleaning pads 2. The brake disc 1 is controlled to rotate, and the brake disc 1 drives the cleaning pads to repeatedly polish the friction plate 13, thereby cleaning the friction plate 13.

[0044] Example 2

[0045] Reference Figure 2 The difference between this embodiment and Embodiment 1 is that a connecting piece 21 is provided between the two cleaning pieces 2 in this embodiment, and the connecting piece 21 is perpendicular to the cleaning pieces 2. The two sides of the connecting piece 21 are respectively connected to the two cleaning pieces 2 to form a U-shaped structure. The connecting piece 21 abuts against the inner sidewall of the brake disc 1, thereby causing the cleaning pieces 2 to rotate in a plane parallel to the brake disc 1, improving the stability of the cleaning pieces 2 in the cleaning process of the friction plate 13.

[0046] The implementation principle of the brake auxiliary cleaning mechanism in this application embodiment is as follows: When the cleaning plate 2 cleans the friction plate 13, the cleaning plate 2 may rotate due to the reaction force of the friction plate 13. By setting a connecting plate 21 to connect the two cleaning plates 2 and making the connecting plate 21 abut against the inner sidewall of the brake disc 1, the rotation of the two cleaning plates 2 is limited, thereby improving the stability of the cleaning plate 2 in the process of cleaning the friction plate 13.

[0047] Example 3

[0048] Reference Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 lies in the structure of the fixing component 3. In this embodiment, the fixing component 3 includes a mounting base 33. The mounting base 33 includes an abutment block 331, a connecting plate 332, and a baffle 333. Two connecting plates 332 are provided, and the two connecting plates 332 are arranged parallel and spaced apart on the abutment block 331, forming a U-shaped structure with an opening on one side. The baffle 333 is located on the connecting plate 332 away from the abutment block 331. The baffle 333 is connected to the two connecting plates 332, thereby sealing the opening of the mounting base 33 and forming a ring structure. The brake disc 1 passes between the two connecting plates 332. The sides of the baffle 333 and the abutment block 331 that are close to each other abut against the inner and outer side walls of the brake disc 1, respectively, thereby realizing the connection between the mounting base 33 and the brake disc 1. The cleaning plate 2 is installed on the side of the connecting plate 332 away from the brake disc 1, realizing the connection between the brake disc 1 and the cleaning plate 2.

[0049] Reference Figure 3 and Figure 4 The baffle 333 is rotatably connected to one of the connecting plates 332. The axis of rotation of the baffle 333 is parallel to the connecting plate 332. Rotating the connecting plate 332 allows the baffle 333 to separate from the connecting plate 332, which is away from its own axis of rotation. At this time, moving the mounting seat 33 radially along the brake disc 1 allows the mounting seat 33 to separate from the brake disc 1, thereby achieving a detachable connection between the cleaning plate 2 and the brake disc 1. A locking screw 34 is provided on the side of the baffle 333 away from the abutment block 331. The screw and locking screw 34 pass through the baffle 333 and abut against the inner wall of the brake disc 1, thereby further fixing the mounting seat 33.

[0050] Reference Figure 3 and Figure 4 During the use of wind power equipment, the wear degree of the friction plate 13 is not uniform, resulting in different gaps between the friction plate 13 and the brake disc 1. Therefore, it is possible that the cleaning plate 2 cannot make contact with the friction plate 13. In order to reduce the occurrence of the above situation, an adjustment component 4 is provided between the cleaning plate 2 and the adjustment plate 44. The adjustment component 4 is used to adjust the distance between the cleaning plate 2 and the connecting plate 332.

[0051] Reference Figure 4 and Figure 5 The adjusting component 4 includes a sliding sleeve 42 of a sliding block 41. The sliding block 41 is welded to the side of the connecting plate 332 near the cleaning piece 2. The sliding sleeve 42 has a cylindrical structure. One end of the sliding sleeve 42 is welded to the side of the cleaning piece 2 near the connecting plate 332, and the other end is mounted on the sliding block 41 in a direction perpendicular to the connecting plate 332, thus achieving a sliding connection between the cleaning piece 2 and the connecting plate 332. A stabilizing groove 43 is formed on the side of the sliding block 41 perpendicular to the connecting plate 332, extending in a direction perpendicular to the connecting plate 332. The stabilizing groove 43 increases the contact area between the sliding sleeves 42 and improves the stability of the cleaning piece 2 during sliding. At the same time, it improves the stability of the sliding block 41 in limiting the rotation of the cleaning piece 2.

[0052] Reference Figure 4 and Figure 5 The adjusting component 4 includes an adjusting plate 44, which has a fan-shaped structure. The adjusting plate 44 is attached to the connecting plate 332 and can rotate around its own axis. A driving inclined surface 46 is provided on the side of the adjusting plate 44 near the cleaning plate 2. The thickness of the driving inclined surface 46 gradually increases along the rotation direction of the adjusting plate 44, and the driving inclined surface 46 abuts against the cleaning plate 2. Rotating the adjusting plate 44 allows the cleaning plate 2 to contact different positions with the adjusting plate 44, thereby changing the distance between the cleaning plate 2 and the connecting plate 332, and realizing the cleaning of friction plates 13 of different thicknesses.

[0053] Reference Figure 4 and Figure 5 The driving inclined surface 46 is a helical surface, meaning that both the inner and outer edges of the driving inclined surface 46 are helical lines with axes parallel to the rotation axis of the adjusting plate 44, and the axis of the helical trajectory of the helical surface coincides with the rotation axis of the adjusting plate 44. The cleaning plate 2 has a contact surface near the adjusting plate 44, which contacts the driving inclined surface 46, thus allowing the adjusting plate 44 to stably support the cleaning plate 2. This reduces the bending of the cleaning plate 2 after contact with the friction plate 13, improving the stability of the cleaning plate 2 during the cleaning process.

[0054] Reference Figure 5 To further improve the stability of the adjusting plate 44 in supporting the cleaning plate 2, multiple adjusting plates 44 can be arranged around their own rotation axis; in this embodiment, two sets are provided. The two sets of adjusting components 4 are located on both sides of the sliding block 41, so that the cleaning plate 2 can be subjected to uniform force, improving the stability of the cleaning plate 2 during movement. An clearance groove is provided on the adjusting plate 44 near the sliding component to facilitate the installation of the sliding block 41 and the sliding sleeve 42.

[0055] Reference Figure 4 and Figure 5 The adjusting assembly 4 also includes a rotating ring 45, which is a circular ring structure and is rotatably connected to the connecting plate 332 around its own axis. Two adjusting plates 44 are welded to the outer wall of the rotating ring 45, realizing the rotatable connection between the adjusting plates 44 and the connecting plate 332. At the same time, the rotating ring 45 connects the two adjusting plates 44, allowing the two adjusting plates 44 to rotate simultaneously, facilitating the user to adjust the position of the cleaning plate 2.

[0056] Reference Figure 4 and Figure 5 A sliding strip 47 is also provided on the side of the cleaning plate 2 near the adjusting plate 44, and the length direction of the sliding strip 47 extends along the spiral trajectory line. A sliding groove is provided on the adjusting plate 44 at the position corresponding to the sliding adjustment, and the sliding strip 47 slides and engages in the sliding groove along the spiral direction. The cross-section of the sliding strip 47 on the plane perpendicular to its own length direction is wedge-shaped to prevent the sliding strip 47 from falling out of the sliding groove. During the rotation of the adjusting plate 44, the sliding strip 47 slides in the sliding groove. Through the engagement of the sliding strip 47 and the sliding groove, the cleaning plate 2 can be prevented from sliding in the direction perpendicular to the connecting plate 332, further improving the stability of the cleaning plate 2 during use.

[0057] Reference Figure 4 and Figure 5 The sliding groove extends through the adjusting piece 44 along its length. Rotating the adjusting piece 44 allows the sliding strip 47 to disengage from the sliding groove. At this time, the sliding cleaning piece 2 can separate from the connecting plate 332, enabling disassembly between the connecting plate 332 and the cleaning piece 2. When installing the cleaning piece 2, the sliding sleeve 42 on the cleaning piece 2 is fitted onto the sliding block 41, and the cleaning piece 2 is pressed down so that the sliding sleeve 42 abuts against the connecting plate 332. Then, the adjusting piece 44 is rotated to bring it closer to the cleaning piece 2. When the sliding strip 47 on the cleaning piece 2 aligns with the sliding groove on the adjusting piece 44, the sliding strip 47 can enter the sliding groove, thus achieving the installation of the cleaning piece 2.

[0058] Reference Figure 3 and Figure 4 A drive assembly 5 is provided on the abutment block 331 to drive the adjusting plate 44 to rotate. The drive assembly 5 includes a drive gear 51 and a connecting shaft 53. There are two drive gears 51, each corresponding to one of the two sets of adjusting assemblies 4. The drive gears 51 are rotatably connected to the mounting base 33 around their own axes. Multiple toothed grooves are formed on the outer wall of the adjusting plate 44 around its own axis, and the drive gears 51 mesh in the toothed grooves; the rotation of the drive gears 51 can drive the adjusting plate 44 to rotate. The connecting shaft 53 is coaxially arranged between the two drive gears 51, and its two ends are welded to the two drive gears 51 respectively. Rotating the connecting shaft 53 can drive the two drive gears 51 to rotate simultaneously, realizing the simultaneous adjustment of the two cleaning plates 2.

[0059] Reference Figure 3 and Figure 4 The drive assembly 5 also includes a worm gear assembly 52. ​​A receiving cavity is formed inside the abutment block 331, and the worm gear assembly 52 is disposed inside the receiving cavity. The worm gear assembly 52 includes a worm wheel and a worm. The worm wheel is coaxially welded to the connecting shaft 53, and the worm meshes with the worm wheel and is rotatably connected to the side wall of the receiving cavity around its own axis. One end of the worm extends outside the mounting base 33 to facilitate rotation of the worm by the user.

[0060] Rotating the worm gear drives the worm wheel, which in turn drives the drive gear 51, thus adjusting the cleaning plate 2. Simultaneously, the reduction and self-locking characteristics between the worm wheel and worm allow for more precise adjustment of the cleaning plate 2's position; and it prevents the adjusting plate 44 from rotating when the cleaning plate 2 is under pressure, improving the stability of the cleaning plate 2 during use. To further facilitate the user's rotation of the worm gear, a knob is welded to one end of the worm gear located outside the mounting base 33; rotating the knob drives the worm gear to rotate.

[0061] The implementation principle of a brake auxiliary cleaning mechanism according to an embodiment of this application is as follows: Rotating the knob drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The rotation of the worm wheel drives two drive gears 51 to rotate simultaneously. When the drive gears 51 rotate, they drive the adjusting plates 44 of the two sets of adjusting components 4 to rotate. When the adjusting plates 44 rotate, the cleaning plate 2 contacts the adjusting plate 44 at different positions, thereby causing the cleaning plate 2 to move closer to or further away from the connecting plate 332, thus changing the distance between the cleaning plate 2 and the friction plate 13 on the brake caliper 12. During the cleaning process of the friction plate 13, the user can gradually adjust the gap between the cleaning plate 2 and the friction plate 13, so that the cleaning plate 2 cleans the oil stains on the friction plate 13 layer by layer.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
