Description

Technical Field

[0001] This invention relates to the field of brakes, and in particular to a yaw brake with a built-in carbon powder collection function. Background Technology

[0002] The yaw brake belongs to the yaw system of the wind turbine. It mainly uses hydraulic force to apply to the built-in friction pads, clamping the friction pads and the brake disc connected to the sliding bearing of the yaw system, thereby realizing the static friction torque and dynamic rotational friction torque of the yaw system, and thus realizing the braking anchoring or yaw rotation of the yaw system.

[0003] During the friction process between the yaw friction pads and the yaw brake disc, a large amount of carbon powder or wear debris is generated. Some of this carbon powder or wear debris falls onto the yaw brake disc and the floor plate inside the yaw system nacelle as the sliding bearing brake rotates. This not only affects the braking effect of the brake on the wind turbine's yaw but also affects the environment inside the yaw system nacelle. At the same time, some carbon powder or wear debris will solidify on the friction pads, causing a change in the friction coefficient of the friction pads. This, in turn, causes a change in the state of the friction pair, and in severe cases, it can produce vibration and abnormal noise.

[0004] Currently, most yaw system brake friction pads and brake discs require manual maintenance for cleaning. Before cleaning, the yaw system must be shut down, which affects power generation. Moreover, the workload for maintenance personnel is large and the time required is long. Wind farm operators urgently need a carbon dust collection device that can automatically clean the surface of the yaw brake disc. Summary of the Invention

[0005] To facilitate the automatic cleaning of carbon powder on the surface of the yaw brake disc, this application provides a yaw brake with a built-in carbon powder collection function.

[0006] This application provides a yaw brake with built-in carbon powder collection function, which adopts the following technical solution:

[0007] A yaw brake with built-in toner collection function includes a brake body for braking a yaw brake disc. The brake body is equipped with a toner collection module, which includes an upper scraping assembly and a lower collection assembly. The upper scraping assembly includes an upper bracket and an upper scraper. The upper bracket is mounted on the brake body, and the upper scraper is mounted on the upper bracket, with the upper scraper abutting against the top of the yaw brake disc. The lower collection assembly includes a lower bracket and a collection box. The lower bracket is mounted on the brake body, and the collection box is mounted on the lower bracket. The collection box is located at the bottom of the yaw brake disc, and the opening of the collection box corresponds to the position of the upper scraper.

[0008] By adopting the above technical solution, the carbon powder collection module can automatically clean and collect carbon powder or wear debris during the operation of the yaw brake. Specifically, when the yaw brake disc rotates, the upper scraper fixed on the brake body can continuously scrape off the carbon powder adhering to the top surface of the brake disc; the scraped carbon powder falls into the corresponding collection box below under the pushing action of the scraper, realizing automatic cleaning without stopping the machine, avoiding power generation loss caused by manual downtime maintenance, significantly reducing maintenance workload and costs, and at the same time, by keeping the friction pair clean, it is easy to effectively maintain a stable friction coefficient, suppress possible vibration and abnormal noise, and ensure the braking reliability of the yaw brake disc.

[0009] Optionally, the upper support includes a fixed frame and a rotating frame. The fixed frame is fixedly installed on the brake body, and the rotating frame is rotatably installed on the fixed frame. The fixed frame is provided with an upper torsion spring that drives the rotating frame to rotate in the direction of the yaw brake disc, and the upper scraper is installed on the rotating frame.

[0010] By adopting the above technical solution, the bottom surface of the upper scraper is kept in contact with the top plane of the yaw system brake disc under the elastic force of the upper torsion spring, thereby automatically compensating for the gap that may be caused by wear or other conditions between the upper scraper and the yaw brake disc, ensuring the stability of the effect of the upper scraper in removing carbon powder or abrasive debris; at the same time, the flexible contact method also avoids the upper scraper from hard scraping the top of the yaw brake disc, preventing damage to the yaw brake disc that may be caused by hard contact.

[0011] Optionally, the upper scraper has at least two vertically extending mounting and adjustment holes. The upper scraper is fixed to the rotating frame by scraper bolts. Multiple scraper bolts are provided in a one-to-one correspondence with the mounting and adjustment holes, and each scraper bolt passes through the rotating frame and each mounting and adjustment hole in sequence.

[0012] By adopting the above technical solution, it is easy to install the upper scraper at different height positions with the rotating frame. This allows the upper scraper to be adapted to the installation of yaw brake discs of different thicknesses, and also facilitates convenient compensation and adjustment of the upper scraper after wear, effectively extending the service life of the scraper.

[0013] Optionally, the rotating frame has a rotation adjustment hole extending horizontally along its own length, and each of the scraper bolts passes through the rotation adjustment hole of the rotating frame.

[0014] By adopting the above technical solution, it is easy to make fine adjustments along the radial direction of the yaw brake disc when installing the upper scraper, so that the yaw brake disc at different radial positions can be adaptively adjusted, which has strong applicability.

[0015] Optionally, the rotating frame includes a rotating fixing part and a rotating adjusting part. The rotating fixing part is rotatably mounted on the fixing frame, and the rotating adjusting part is rotatably mounted on the rotating fixing part. The rotating fixing part has a circumferential adjusting hole that extends circumferentially around the rotation point of the rotating adjusting part and is vertically penetrating it. The rotating adjusting part is fixed to the rotating fixing part by bolts that pass through itself and the circumferential adjusting hole.

[0016] By adopting the above technical solution, the rotating frame is divided into a rotating fixed part and a rotating adjustment part, and a circumferential adjustment hole is provided, so that the upper scraper can be slightly rotated and adjusted on the scraping plane at the bottom during installation. This makes it easier to ensure that the upper scraper can fit the yaw brake disc surface at the best angle, achieving a more uniform, more efficient and less wear-prone cleaning effect.

[0017] Optionally, a collection baffle is provided on the top of the collection box. The collection baffle is located between the collection box and the brake body, and the collection baffle is inclined from top to bottom toward the opening of the collection box.

[0018] By adopting the above technical solution, the baffle effectively guides the scraped carbon powder or wear debris, making it less likely for the scraped carbon powder or wear debris to fall through the gap between the collection box and the brake body, and facilitating the precise introduction of the scraped carbon powder or wear debris into the collection box.

[0019] Optionally, a sealing strip is installed at the end of the collecting baffle away from the collecting box, and the side of the sealing strip away from the collecting baffle abuts against the brake body.

[0020] By adopting the above technical solution, it is easier to effectively fill the gap that may be caused by the difference in shape between the collecting baffle and the brake body, and further ensure that the scraped carbon powder or wear debris is stably guided into the collecting box.

[0021] Optionally, the lower support has multiple collection and fixing holes extending horizontally, and the collection box is fixed to the lower support by lower bolts. Multiple lower bolts are provided in a one-to-one correspondence with the collection and fixing holes, and each lower bolt passes through each collection and fixing hole and the collection box in sequence.

[0022] By adopting the above technical solution, it is easy to make slight adjustments to the horizontal position of the collection box opening, thereby ensuring that the scraped carbon powder or abrasive debris can fall accurately into the collection box, effectively avoiding the spillage of carbon powder or abrasive debris due to misalignment. At the same time, it is convenient to install the collection box after the sealing strip is installed against the brake body in the horizontal direction, which helps to ensure the sealing effect of the sealing strip on the gap between the collection baffle and the brake body.

[0023] Optionally, the collection box is provided with a push plate and a push plate moving assembly. There are two push plates. The push plate moving assembly is used to push the two push plates to move in a direction that moves closer to or further away from each other. A through-hole is provided in the middle of the collection box. A material picking box is installed at the bottom of the collection box. The top opening of the material picking box corresponds to the material dropping hole.

[0024] By adopting the above technical solution, the pusher plate motion assembly drives the two pusher plates to move towards the center of the collection box, which facilitates the squeezing of waste materials, such as carbon powder or grinding debris, from both sides to the center of the collection box, and pushes the waste materials into the dispensing box through the discharge hole. The cleaning of the collection box only requires replacing or emptying the dispensing box, which is simple to operate.

[0025] Optionally, the material collection box is fixedly installed with two connecting side plates. The connecting side plates are provided with a first locking block and a second locking block. The first locking block is fixedly installed on the top of the connecting side plate, and the second locking block is slidably engaged with the connecting side plate. Both ends of the first locking block and the second locking block are provided with locking wedge surfaces. The locking wedge surfaces of the first locking block and the second locking block face the top and the bottom, respectively. The dimension of the second locking block facing the first locking block is larger than the dimension of the first locking block facing the second locking block. The collection box is provided with locking components on both sides, corresponding to the two connecting side plates. The locking components include locking blocks and locking springs. The locking block is provided with a locking wedge surface on the side facing the connecting side plate. The locking spring applies a spring force to the locking block to move in the direction of the connecting side plate.

[0026] By adopting the above technical solution, when installing the material picking box, simply push the box upwards so that the locking block is engaged between the first and second locking blocks under the action of the spring, thereby fixing the position of the material picking box. When disassembling, continue to push the material picking box upwards. When the second locking block is at the top of the locking block, pull the material picking box downwards to remove it. This makes the disassembly and assembly of the material picking box simple and facilitates quick cleaning and maintenance.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the yaw brake disc rotates, the upper scraper fixed on the brake can continuously scrape off the carbon powder adhering to the top surface of the brake disc; the scraped carbon powder falls into the corresponding collection box below under the pushing action of the scraper, realizing automatic cleaning without stopping the machine, avoiding the loss of power generation caused by manual shutdown maintenance, significantly reducing maintenance workload and cost, and at the same time, by keeping the friction pair clean, it is easy to effectively maintain a stable friction coefficient, suppress possible vibration and abnormal noise, and ensure the braking reliability of the yaw brake disc.

[0029] 2. Under the elastic force of the upper torsion spring, the bottom surface of the upper scraper keeps its own bottom surface in contact with the top plane of the yaw system brake disc, thereby automatically compensating for the gap that may be caused by wear or other conditions between the upper scraper and the yaw brake disc, ensuring the stability of the effect of the upper scraper in removing carbon powder or wear debris.

[0030] 3. The baffle plate effectively guides the scraped carbon powder or wear debris, preventing it from falling through the gap between the collection box and the brake body, and facilitating the precise introduction of the scraped carbon powder or wear debris into the collection box.

[0039] The following is in conjunction with the appendix Figure 1-6This application will be described in further detail.

[0040] This application discloses a yaw brake with built-in carbon powder collection function. Example 1

[0041] Reference Figure 1 The yaw brake with built-in carbon powder collection function includes a brake body 1 for braking the yaw brake disc 01. The brake body 1 is provided with a carbon powder collection module. In this embodiment, the brake body 1 is located inside the yaw brake disc 01.

[0042] Reference Figure 1 and Figure 2 The toner collection module includes an upper scraping assembly and a lower collection assembly. The upper scraping assembly includes an upper bracket 2 and an upper scraper 3. The upper bracket 2 is installed on the brake body 1. Specifically, the upper bracket 2 includes a fixed frame 201 and a rotating frame 202. The fixed frame 201 is fixedly installed on the brake body 1 by screws. The rotating frame 202 is rotatably installed on the fixed frame 201 by a horizontally set rotating shaft. The fixed frame 201 is provided with an upper torsion spring 4. In this embodiment, two upper torsion springs 4 are provided along the axis of the rotating shaft. One end of the upper torsion spring 4 abuts against the fixed frame 201 and the other end abuts against the rotating frame 202 to apply a spring force to the rotating frame 202 to rotate in the direction of the yaw brake disc 01.

[0043] Continue to refer to Figure 1 and Figure 2 The upper scraper 3 is vertically installed on the rotating frame 202. The bottom of the upper scraper 3 abuts against the top of the yaw brake disc 01. The longitudinal section of the bottom of the upper scraper 3 is flared to facilitate the stable scraping of carbon powder or wear debris when the yaw brake disc 01 rotates around its own axis.

[0044] Reference Figure 2 and Figure 3 In this embodiment, the upper scraper 3 has two vertically extending mounting adjustment holes 5, which are distributed along the length of the upper scraper 3. The rotating frame 202 has a horizontally extending rotation adjustment hole 6. The upper scraper 3 is fixed to the rotating frame 202 by scraper bolts. Two scraper bolts are provided, one for each mounting adjustment hole 5. The threaded portions of the two scraper bolts pass through the rotation adjustment hole 6 of the rotating frame 202 and the two mounting adjustment holes 5, respectively, so as to achieve a stable fixation of the upper scraper 3 in position through the cooperation with the nut. The mounting adjustment holes 5 and the rotation adjustment holes 6 facilitate the upper scraper 3 to be adapted to the installation of yaw brake discs 01 of different thicknesses and yaw brake discs 01 of different radial positions, making it highly applicable.

[0045] Reference Figure 1 and Figure 2 The lower collection component includes a lower bracket 7 and a collection box 8. The lower bracket 7 is installed on the brake body 1, and the collection box 8 is installed on the lower bracket 7. The collection box 8 is located at the bottom of the yaw brake disc 01. The opening of the collection box 8 corresponds to the position of the upper scraper 3 so that the collection box 8 can receive the carbon powder or wear debris scraped off by the upper scraper 3.

[0046] Reference Figure 2 and Figure 3 In this embodiment, the lower support 7 has four rectangular collection and fixing holes 9 that extend horizontally. The collection box 8 is fixed to the lower support 7 by lower bolts. There are four lower bolts corresponding to the collection and fixing holes 9. The threaded part of each lower bolt passes through each collection and fixing hole 9 and the collection box 8 in sequence, and fixes the position of the collection box 8 by cooperating with the nut. The setting of the collection and fixing holes 9 makes it easy to make slight adjustments to the horizontal position of the opening of the collection box 8, thereby ensuring that the scraped toner or abrasive can fall accurately into the collection box 8, effectively avoiding the spillage of toner or abrasive due to misalignment.

[0047] Reference Figure 2 A collection baffle 10 is provided on the top of the collection box 8. The collection baffle 10 is located between the collection box 8 and the brake body 1. The collection baffle 10 is inclined from top to bottom towards the opening of the collection box 8, so as to effectively guide the scraped carbon powder or wear debris, making it difficult for the scraped carbon powder or wear debris to fall through the gap between the collection box 8 and the brake body 1.

[0048] Continue to refer to Figure 2 A sealing strip 11 is installed at the end of the collecting baffle 10 away from the collecting box 8. A collecting groove 12 is formed on the side of the sealing strip 11 facing the collecting baffle 10. Elastic pads 13 are fixedly connected to the two opposite walls of the collecting groove 12. The collecting baffle 10 is snapped into the collecting groove 12, and each elastic pad 13 presses against the collecting baffle 10 to ensure the connection stability between the collecting baffle 10 and the sealing strip 11. The side of the sealing strip 11 away from the collecting baffle 10 presses against the brake body 1 to further effectively fill the gap that may be caused by the difference in shape between the collecting baffle 10 and the brake body 1, ensuring that the scraped carbon powder or wear debris is stably guided into the collecting box 8.

[0049] Reference Figure 1In addition, in this embodiment of the application, the yaw brake disc 01 body has a plurality of material passage holes 14 that are evenly distributed and penetrate around its own axis. When the material passage hole 14 is rotated to a position close to the brake body 1, it corresponds to the end position of the upper scraper 3. At this time, the material passage hole 14 is located at the top opening of the collection box 8, i.e., the box opening, so that carbon powder or grinding debris can fall into the collection box 8 from the other end of the upper scraper 3 through the material passage hole 14 for centralized collection and processing.

[0050] The implementation principle of Example 1 is as follows: When the yaw brake disc 01 rotates, the upper scraper 3 fixed on the brake body 1 can continuously scrape off the carbon powder attached to the top surface of the brake disc; the scraped carbon powder falls into the collection box 8 corresponding to the lower position under the pushing action of the scraper, realizing automatic cleaning without stopping the machine, avoiding the loss of power generation caused by manual shutdown maintenance, significantly reducing the maintenance workload and cost, and at the same time, by keeping the friction pair clean, it is easy to effectively maintain a stable friction coefficient, suppress possible vibration and abnormal noise, and ensure the braking reliability of the yaw brake disc 01. Example 2

[0051] Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the rotating frame 202 in this embodiment includes a rotating fixing part 2021 and a rotating adjusting part 2022. The rotating fixing part 2021 is rotatably mounted on the fixed frame 201 via a rotating shaft. One end of the upper torsion spring 4 abuts against the fixed frame 201 and the other end abuts against the rotating fixing part 2021 of the rotating frame 202.

[0052] Reference Figure 5 The rotation adjustment part 2022 is rotatably mounted on the rotation fixing part 2021 via a vertically set rotating shaft. The rotation fixing part 2021 has a circumferential adjustment hole 15 that extends circumferentially around the rotation point of the rotation adjustment part 2022, i.e., the vertically set rotating shaft, and passes through it vertically. The rotation adjustment part 2022 is fixed to the rotation fixing part 2021 by bolts that pass through itself and the circumferential adjustment hole 15, so that the upper scraper 3 can make a slight angle rotation adjustment on its bottom scraping plane during installation, thereby ensuring that the upper scraper 3 can fit the surface of the yaw brake disc 01 at the best angle.

[0053] Reference Figure 5 and Figure 6 In addition, the collection box 8 in this embodiment is provided with a push plate 16 and a push plate 16 moving assembly. There are two push plates 16 facing each other. The bottom of the two push plates 16 abuts against the inner bottom wall of the collection box 8. The push plate 16 moving assembly is used to push the two push plates 16 to move towards each other or away from each other, so that the two push plates 16 push the carbon powder or grinding debris in the collection box 8 to the middle of the collection box 8.

[0054] Reference Figure 6 The pusher plate 16 motion assembly includes a bidirectional lead screw 17 and a pusher plate motor 18. The bidirectional lead screw 17 is horizontally rotatably mounted on the collection box 8 and located outside the collection box 8. The pusher plate motor 18 is mounted on the collection box 8 and is used to drive the bidirectional lead screw 17 to rotate. Both pushers 16 are fixedly connected to drive plates 19, which extend out of the collection box 8. The two ends of the bidirectional lead screw 17 with opposite thread directions are respectively threaded through the two drive plates 19 and threadedly engaged with the drive plates 19, so that when the bidirectional lead screw 17 rotates, the two drive plates 19 drive the two pushers 16 to move in a direction closer to or further away from each other.

[0055] Reference Figure 5 and Figure 6 The collection box 8 has a through-hole 20 in the middle, and a receiving box 21 is installed at the bottom of the collection box 8. The top opening of the receiving box 21 corresponds to the discharge hole 20, so that the receiving box 21 can receive the waste in the collection box 8. Specifically, the receiving box 21 is fixedly installed with two connecting side plates 22. The connecting side plates 22 are provided with a first locking block 23 and a second locking block 24. The first locking block 23 is fixedly installed on the top of the connecting side plate 22, and the second locking block 24 slides vertically and engages with the connecting side plate 22. Both ends of the first locking block 23 and the second locking block 24 are provided with locking wedge surfaces 25. The locking wedge surfaces 25 of the first locking block 23 and the second locking block 24 face the top and the bottom respectively. The size of the second locking block 24 facing the first locking block 23 is larger than the size of the first locking block 23 facing the second locking block 24. A connecting block 26 is fixedly installed on the connecting side plate 22. The connecting block 26 is located on the side of the second locking block 24 away from the first locking block 23, so as to limit the sliding of the second locking block 24.

[0056] Continue to refer to Figure 5 and Figure 6 The collection box 8 has two locking components on each side, corresponding to the two connecting side plates 22. Each locking component includes a locking block 27 and a locking spring 28. In this embodiment, each set of locking components has two locking blocks 27 and two locking springs 28 facing each other. Each set of two locking blocks 27 has a locking wedge surface 271 on the side facing the connecting side plate 22. One end of the locking spring 28 is connected to the locking block 27 and the other end is connected to the collection box 8, so that the locking spring 28 can apply a spring force to the locking block 27 to move in the direction of the connecting side plate 22. Two collection limiting plates 29 are fixedly installed on both sides of the collection box 8. After the material taking box 21 is installed, the two ends of the first locking block 23 abut against the two collection limiting plates 29 respectively to further ensure the stability of the position of the material taking box 21 after installation.

[0057] When installing the material picking box 21, simply push the material picking box 21 upwards so that the locking block 27 is locked between the first locking block 23 and the second locking block 24 under the action of the spring, thereby fixing the position of the material picking box 21. When disassembling, continue to push the material picking box 21 upwards. When the second locking block 24 is at the top of the locking block 27, pull the material picking box 21 downwards to remove it, thus making the disassembly and assembly of the material picking box 21 simple.

[0058] The implementation principle of Embodiment 2 is as follows: The implementation principle of this embodiment is the same as that of Embodiment 1. The main difference is that in this embodiment, it is convenient to push the waste into the material collection box 21 through the material drop hole 20. The cleaning work of the collection box 8 only requires replacing or emptying the material collection box 21. The operation is simple, and the installation and disassembly of the material collection box 21 are simple, which facilitates the quick cleaning and maintenance of the material collection box 21.

[0059] 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.
