Description

Technical Field

[0001] This invention relates to the field of automated turning equipment technology, and in particular to a turning device and method for turning wind turbine brake discs. Background Technology

[0002] The main function of the wind turbine brake disc is to work with the brake caliper to quickly stop the rotating parts of the wind turbine through friction during emergencies, maintenance, or normal shutdown, ensuring the safety of equipment and personnel. At the same time, in the yaw system, it works with the brake caliper to control the rotation of the nacelle, so that the blades are always aligned with the wind direction to improve power generation efficiency.

[0003] As brake discs rub against brake pads over a long period of time, uneven wear, scratches, grooves, or thermal cracks may appear on their surface. This results in a reduced contact area and unstable friction during braking, affecting braking performance. Therefore, a brake disc turning device is needed to remove these damaged layers, making the brake disc surface smooth and flat again, and restoring normal frictional contact.

[0004] Traditional wind turbine brake disc turning devices rely on cranes and forklifts for machining brake discs due to the large individual mass of the brake discs. This process can only process one brake disc at a time and requires multiple uses of the lifting equipment, resulting in low efficiency. Furthermore, when using lifting equipment to lift the brake discs, the discs are prone to shaking and misalignment, which can damage the brake discs or cause them to jam, posing certain safety hazards.

[0005] Therefore, it is necessary to provide a wind turbine brake disc turning device and turning method to solve the above-mentioned technical problems. Summary of the Invention

[0022] Compared with related technologies, the wind turbine brake disc turning device provided by the present invention has the following advantages:

[0023] This invention provides a wind turbine brake disc turning device and method. Through the cooperation of a transfer component, turntable, first cylinder, and chuck, the device enables automatic loading, unloading, and repositioning of the brake disc on the chuck, eliminating the need for manual intervention or hoisting equipment. This significantly improves loading and unloading efficiency. Furthermore, inserting the insertion rod into the positioning hole on the brake disc prevents collisions and displacement during loading and unloading. The cooperation of the transport mechanism and fixing frame completely eliminates reliance on hoisting equipment, adapting to the loading needs of different quantities of brake discs. It can efficiently complete both batch and single loading. Moreover, when a certain number of brake discs are concentrated in the collection box, starting the first motor and first hydraulic cylinder enables automatic loading, avoiding problems such as brake disc collisions and alignment deviations caused by improper operation during manual handling or hoisting.

[0024] The combination of rectangular grooves, rollers, and a collection trough allows the brake disc to be easily moved within the collection box, facilitating its rapid transfer to the chuck position without relying on lifting equipment or laborious manual handling. The lubricant spraying component, working in conjunction with the collection box, allows the dry lubricant to form a protective film on the outer wall of the brake disc. When the air bladder is pressed, the sprayed dry lubricant reduces friction and wear between the inner wall of the collection box and the outer wall of the brake disc, preventing scratches or damage caused by relative movement. Simultaneously, the lubricant reduces contact resistance, making the brake disc easier to place and remove within the box or move with the box, reducing jamming. Pressing the air bladder also allows for controllable use of dry lubricant, preventing waste.

[0025] With the help of the flipping mechanism, the brake disc can be flipped automatically without manual flipping or reliance on lifting equipment to adjust the direction. This is especially useful in scenarios where both sides of the brake disc are machined, avoiding the safety risks of flipping heavy workpieces. For brake discs with uneven weight, the arc-shaped clamping plate, arc-shaped support seat and support plate can stably clamp and control the flipping, preventing the workpiece from colliding or falling due to the shift of the center of gravity. Furthermore, by cooperating with the transfer component, it can prevent the brake disc from being bumped or displaced during loading and unloading.

[0026] This invention provides a method for machining a wind turbine brake disc. The machining method uses the aforementioned wind turbine brake disc machining device to effectively reduce manpower input, eliminates the need for manual labor or hoisting equipment, and significantly improves loading and unloading efficiency.

[0049] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0050] First embodiment:

[0051] Please refer to the following: Figures 1-12In the first embodiment of the present invention, the wind turbine brake disc turning device includes: a base 1, a two-dimensional translation stage 6, a cutting tool 7, and four chucks 17. The two-dimensional translation stage 6 is installed on the top of the base 1, and a tool holder is also fixedly installed on the top of the two-dimensional translation stage 6. The cutting tool 7 is set on the tool holder. The four chucks 17 are all set inside the base 1. The base 1 has a semi-circular groove, and a turntable 8 is rotatably installed in the semi-circular groove. Two load-bearing shafts are also rotatably installed in the semi-circular groove. The two load-bearing shafts can support the turntable 8 and can rotate with the turntable 8. A second motor 9 is fixedly installed on the top of the base 1. The output shaft is fixedly connected to the turntable 8. The turntable 8 has four first through holes, each containing a first cylinder 13 rotatably mounted. Four chucks 17 are fixedly mounted within each of the four first cylinders 13. Each of the four first cylinders 13 contains a transfer assembly for moving the brake disc out of or into the chuck 17. This enables automatic loading, unloading, and resetting of the brake disc 14 on the chuck 17 without manual intervention or hoisting equipment, significantly improving loading and unloading efficiency. Furthermore, inserting the insertion rod 15 into the positioning hole on the brake disc 14 prevents the brake disc from bumping or shifting during loading and unloading. Four third motors 18 are fixedly installed inside, and the four third motors 18 are respectively connected to the four first cylinders 13. The outer wall of the first cylinder 13 is fixedly installed with a second gear 12. The output shaft of the third motor 18 is fixedly installed with a first gear 11, which meshes with the second gear 12. Transparent baffles 10 are fixedly installed on both sides of the cutting tool 7. A dust collection hopper 29 is fixedly installed in the semi-circular groove. One end of a sewage discharge pipe 30 is fixedly installed at the bottom of the dust collection hopper 29, and the other end of the sewage discharge pipe 30 extends to the outside of the base 1. During the turning process, the transparent baffles 10 on both sides of the cutting tool 7 prevent debris from splashing. Debris falls into the dust collection hopper 29 and is discharged from the base 1 through the sewage pipe 30. A conveying port is provided on one inner wall of the semi-circular groove. A fixed frame 3 is fixedly installed on one side of the base 1. A transport mechanism is provided on the fixed frame 3. The transport mechanism is used to transport the brake disc to the chuck, which can completely eliminate the dependence on hoisting equipment and adapt to the feeding needs of different numbers of brake discs. Secondly, when a certain number of brake discs are collected in the collection box 2, the first motor 4 and the first hydraulic cylinder 21 can be started to realize automatic feeding, which can avoid problems such as brake disc collisions and alignment deviations caused by improper operation during manual handling or hoisting.

[0052] Each transfer assembly includes two electric push rods 19, an annular plate 16, and multiple insert rods 15. The electric push rods 19 are fixedly installed inside the first cylinder 13. The first cylinder 13 has an annular groove at one end near the cutter 7. The annular plate 16 is located in the annular groove. The telescopic ends of the electric push rods 19 extend into the annular groove and are fixedly connected to the annular plate 16. The four insert rods 15 are fixedly installed on the side of the annular plate 16 away from the electric push rods 19. The brake disc in the central box 2 is pushed so that it enters the semi-circular groove of the base 1 through the conveying port and is aligned with one of the chucks 17. The corresponding two electric push rods 19 in the first cylinder 13 are activated. Their telescopic ends push the annular plate 16 toward the brake disc, so that the four insert rods 15 are inserted into the positioning holes of the brake disc and then move toward the chuck 17 to fix the brake disc on the chuck 17.

[0053] The transport mechanism includes a first motor 4, a screw 5, a limiting displacement conveying frame 20, a first hydraulic cylinder 21, a transfer box 23, and a concentrator 2. The first motor 4 is fixedly mounted on the top of the fixed frame 3. One end of the screw 5 is fixedly connected to the output shaft of the first motor 4, and the other end of the screw 5 is rotatably mounted on one side of the base 1. The limiting displacement conveying frame 20 is disposed inside the fixed frame 3. A sleeve plate is threadedly connected to the outer side of the screw 5, and the sleeve plate is fixedly connected to the limiting displacement conveying frame 20. The transfer box 23 is slidably mounted on one side of the limiting displacement conveying frame 20. The first hydraulic cylinder 21 is fixedly mounted on one side of the transfer box 23, and the telescopic end of the first hydraulic cylinder 21 extends into the transfer box 23 and is fixedly mounted with a top block 22. The concentrator 2 is slidably mounted inside the transfer box 23. The concentrator 2 has a second through hole. One end of a U-shaped lifting frame 25 is hinged to the side of the concentrator 2 away from the base 1. The U-shaped lifting frame 25 is provided with two blind slots, and a lifting plate 27 is slidably installed in each of the two blind slots. One end of two first springs 28 is fixedly installed on the side of the two lifting plates 27 that are far apart from each other. The other end of the two first springs 28 is fixedly connected to the inner wall of the blind slot. The U-shaped lifting frame 25 is also provided with four insertion holes, and two reinforcing rods 26 are installed in the four insertion holes. When the second hydraulic cylinder 24 is activated, the second hydraulic cylinder 24 drives the U-shaped lifting frame 25 to descend. At this time, the lifting plate 27 contacts the brake disc and is pushed back into the blind slot. When it continues to descend, the lifting plate 27 extends and contacts the bottom of the brake disc. The wind turbine brake disc is located on the U-shaped lifting frame 25. The two reinforcing rods 26 are inserted into the insertion holes again for further reinforcement to ensure the stability of the brake disc. Two second hydraulic cylinders 24 are hinged on the side of the central box 2 that is far away from the base 1. The extension and retraction ends of the two second hydraulic cylinders 24 are hinged to the U-shaped lifting frame 25.

[0054] The working principle of the wind turbine brake disc turning device provided by this invention is as follows:

[0055] First, slide the central box 2 out of the transfer box 23, remove the two reinforcing rods 26, and start the second hydraulic cylinder 24. The second hydraulic cylinder 24 drives the U-shaped lifting frame 25 to descend. At this time, the lifting plate 27 contacts the brake disc and is pushed back into the blind groove. When it continues to descend, the lifting plate 27 extends and contacts the bottom of the brake disc. The wind turbine brake disc is located on the U-shaped lifting frame 25. Insert the two reinforcing rods 26 into the insertion hole again to further reinforce and ensure the stability of the brake disc. Start the second hydraulic cylinder 24. Its telescopic end drives the U-shaped lifting frame 25 to rise, raising the brake disc to the height aligned with the second through hole of the central box 2. The brake disc slides into the second through hole. Then the U-shaped lifting frame 25 continues to descend and raises the next brake disc. When the next brake disc is raised to the second through hole, it will push the brake disc in the second through hole to move forward, thus concentrating multiple brake discs.

[0056] Once all four brake discs in the second through hole are assembled, the second hydraulic cylinder 24 is activated, raising the U-shaped lifting frame 25 into the concentrator box 2. The concentrator box 2 is then slid into the transfer box 23. The first motor 4 is activated, and its output shaft drives the screw 5 to rotate, causing the transfer box 23 to slide into the conveying port. The first hydraulic cylinder 21 is then activated, its telescopic end driving the top block 22 to push the brake discs in the concentrator box 2, allowing them to pass through the conveying port into the semi-circular groove of the base 1. Aligning with one of the chucks 17, the two corresponding electric push rods 19 in the first cylinder 13 are activated, their telescopic ends pushing the annular plate 16 towards the brake disc, causing the four insert rods 15 to be inserted into the positioning holes of the brake disc. Then move to chuck 17 to fix the brake disc on chuck 17. Then start the second motor 9. The output shaft of the second motor 9 drives the turntable 8 to rotate, so that the chuck 17 without the brake disc is rotated to the conveyor. Repeat the above steps to fix the other brake discs to be processed on the chuck 17 of the other three first cylinders 13 respectively. Start the second motor 9 to drive the turntable 8 to rotate and rotate the first cylinder 13 with the brake disc fixed to the processing position corresponding to the cutting tool 7. Start the third motor 18 to drive the first cylinder 13 and the brake disc to rotate. At the same time, slide the two-dimensional translation stage 6 to adjust the position of the cutting tool 7 so that it contacts the brake disc and start the turning operation.

[0057] During the turning process, the transparent baffles 10 on both sides of the cutter 7 prevent debris from splashing. The debris falls into the dust collection hopper 29 and is discharged from the base 1 through the drain pipe 30. After one brake disc is processed, the sliding two-dimensional translation stage 6 moves the cutter 7 away from the brake disc, the third motor 18 is turned off, and the second motor 9 is started, driving the turntable 8 to rotate and move the next brake disc to the processing position. The turning operation is repeated to achieve continuous processing. When the last brake disc is processed, the second motor 9 drives the processed brake disc to rotate to the conveyor. At the location, the electric push rod 19 of the corresponding conveying port is activated, causing the annular plate 16 to move towards the brake disc. The insert rod 15 is inserted into the positioning hole of the brake disc, causing the chuck 17 to release the brake disc. The electric push rod 19 conveys the processed brake disc to the collection box 2 through the annular plate 16 and the insert rod 15. After completion, the turntable 8 continues to rotate until all the brake discs on the four chucks 17 are conveyed into the collection box 2. Then, the first motor 4 is activated, causing the transfer box 23 to move out of the base 1. The collection box 2 is slid out, and the brake discs in the collection box 2 are taken out.

[0058] Second embodiment:

[0059] Based on the wind turbine brake disc turning device provided in the first embodiment of this application, the second embodiment of this application proposes another wind turbine brake disc turning device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0060] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0061] Please refer to the following: Figures 13-16 The wind turbine brake disc turning device also includes two rectangular slots 35, both of which are located on the inner wall of the second through hole. Three rollers 37 are rotatably installed in each of the two rectangular slots 35. These rollers 37 allow the brake disc 14 to be easily moved within the central box 2, facilitating rapid transfer of the brake disc to the chuck 17 without relying on hoisting equipment or laborious manual handling. The outer walls of the three rollers 37 are each provided with multiple storage slots. The inner wall of the second through hole also has two material collection slots 36, with each end of the two material collection slots connected to two… The rectangular slots 35 are connected, and the collection box 2 is equipped with two sets of lubricant spraying components. The lubricant spraying components are used to spray lubricant onto the roller 37. Since the dry lubricant can form a protective film on the outer wall of the brake disc 14, when the airbag 31 is pressed, the dry lubricant sprayed by the nozzle 38 can reduce the friction and wear when the inner wall of the collection box 2 contacts the outer wall of the brake disc 14, and avoid scratches or damage caused by relative movement. At the same time, the lubricant can reduce the contact resistance, making the brake disc easier to put in and take out of the box or move with the box, and reducing jamming.

[0062] Each lubricant spraying assembly includes an airbag 31, a storage tank 34, three feed pipes 33, three nozzles 38, and a one-way valve 39. The top of the collection tank 2 is provided with a hidden groove, and the airbag 31 is fixedly installed in the hidden groove. The storage tank 34 is fixedly installed on one side of the collection tank 2. One end of the air supply pipe 32 is fixedly installed on one side of the airbag 31, and the other end of the air supply pipe 32 extends into the storage tank 34. One end of each of the three feed pipes 33 is located in the storage tank 34. The three nozzles 38 are fixedly installed in the rectangular groove 35, and the other ends of the three feed pipes 33 are fixedly connected to the three nozzles 38 respectively. The top of the storage tank 34 is fixedly installed with a dispensing pipe 41, and the top of the dispensing pipe 41 is provided with a sealing cap 40. The one-way valve 39 is fixedly installed on the top of the sealing cap 40. By pressing the airbag 31, the amount of dry lubricant used can be controlled to avoid waste.

[0063] The outer wall of the sealing cap 40 is provided with two annular grooves, and a rubber ring is fixedly installed in each of the two annular grooves. The outer walls of the two rubber rings are in contact with the inner wall of the dispensing tube 41.

[0064] After the brake disc is transferred to the second through hole of the collection box 2 via the U-shaped lifting frame 25, the brake disc in the second through hole will be pushed and moved deeper into the second through hole by the next brake disc. At this time, the three rollers 37 in the rectangular groove 35 contact the outer wall of the brake disc. As the brake disc moves, the rollers 37 rotate passively, and the storage groove on their outer wall carries a small amount of lubricant that sticks to the outer wall of the brake disc, reducing the friction between the brake disc and the inner wall of the second through hole. When the lubricant in the storage groove on the rollers 37 is insufficient, the operator can press the air bladder 31 in the hidden groove at the top of the collection box 2. The gas in the air bladder 31 is forced into the storage box 34 through the air supply pipe 32, so that the lubricant in the box is delivered to the storage box 34 through the three feeding pipes 33. Three nozzles 38 within the rectangular groove 35 spray onto the roller 37 and the rectangular groove 35, eventually contacting the brake disc. A one-way valve 39 replenishes air to the storage tank 34 when the airbag 31 resets, causing the airbag 31 to inflate again, ensuring stable subsequent spray pressure. Some lubricant within the rectangular groove 35 flows into the connected collection trough 36, adhering to the bottom outer wall of the brake disc. When the lubricant in the storage tank 34 is insufficient, the sealing cover 40 is opened, and new lubricant is added through the dispensing pipe 41. When the sealing cover 40 is replaced, its outer rubber ring contacts the inner wall of the dispensing pipe 41 tightly, achieving a seal and preventing lubricant and air leakage or the entry of external impurities.

[0065] Third embodiment:

[0066] Based on the wind turbine brake disc turning device provided in the second embodiment of this application, the third embodiment of this application proposes another wind turbine brake disc turning device. The third embodiment is merely a preferred embodiment of the second embodiment, and the implementation of the third embodiment will not affect the separate implementation of the second embodiment.

[0067] The third embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0068] Please refer to the following: Figures 17-21 The wind turbine brake disc turning device also includes a first frame, which is fixedly installed on the top of the base 1. A flipping mechanism is provided on the first frame. The flipping mechanism is used to change the face of the brake disc without manual flipping or relying on hoisting equipment to adjust the direction. It is especially suitable for scenarios where both sides of the brake disc are turned, avoiding the safety risks when flipping heavy workpieces. For brake discs 14 with uneven weight, the linear bearing 51 and the L-shaped arc clamp 50 are used to stably clamp and control the flipping, preventing the workpiece from colliding or falling due to the shift of the center of gravity. The flipping mechanism is located between the turntable 8 and the two-dimensional translation stage 6.

[0069] The tilting mechanism includes a third hydraulic cylinder 42, an arc-shaped clamping plate 50, a connecting rod 46, a fourth motor 44, an arc-shaped support 45, and two fourth hydraulic cylinders 43. A linear bearing 51 is fixedly installed inside the first frame. The connecting rod 46 passes through and slides on the linear bearing 51, allowing it to rotate and move up and down. The bottom end of the connecting rod 46 extends into the first frame. The arc-shaped clamping plate 50 is located inside the first frame, and the bottom end of the connecting rod 46 is fixedly installed on the top of the arc-shaped clamping plate 50. The arc-shaped clamping plate 50 applies a downward pressure brake. When the brake disc is turned, it causes the arc-shaped support seat 45 to descend, then the fourth motor 44 is activated. The output shaft of the fourth motor 44 drives the fourth gear 57 to rotate, which in turn drives the connecting rod 46 to rotate via the third gear 47. The connecting rod 46 drives the brake disc to rotate 180 degrees via the arc-shaped clamp 50. As the brake disc rotates, the rotating seat 54 also rotates, completing the flipping. The second frame is fixedly installed on the top of the first frame, and the third hydraulic cylinder 42 is fixedly installed on the top of the second frame. The telescopic end of the third hydraulic cylinder 42 rotates with the top of the connecting rod 46. The fourth motor 44 is fixedly installed inside the second frame and is connected to the connecting rod 46. A third gear 47 is fixedly installed on the outer wall of the connecting rod 46, and a fourth gear 57 is fixedly installed on the output shaft of the fourth motor 44. The third gear 47 and the fourth gear 57 mesh with each other. An arc-shaped support seat 45 is installed above the base 1. A guide rod 55 is fixedly installed on the top of the base 1. The arc-shaped support seat 45 is slidably installed on the guide rod 55, and the guide rod 55 can control the movement direction of the arc-shaped support seat 45. The inner wall of the curved support 45 is provided with a circular groove, and a support plate 53 is provided in the circular groove. The top of the support plate 53 is provided with an arc-shaped groove. A rotating seat 54 is also rotatably installed on the top of the base 1. The top of the rotating seat 54 extends into the circular groove and is fixedly connected to the support plate 53. Two fixed trapezoidal blocks 59 are fixedly installed at the bottom of the arc-shaped support 45. Two movable trapezoidal blocks 52 are slidably installed on the top of the base 1. Two fourth hydraulic cylinders 43 are fixedly installed on both sides of the first frame, and the telescopic ends of the two fourth hydraulic cylinders 43 extend into the first frame.

[0070] The two fixed trapezoidal blocks 59 and the two movable trapezoidal blocks 52 are provided with inclined surfaces on the side that are close to each other, and the inclined surfaces of the fixed trapezoidal blocks 59 and the movable trapezoidal blocks 52 are in contact.

[0071] After the brake disc is machined on one side of the chuck 17, the electric push rod 19 is activated first. The electric push rod 19 moves the annular plate 16 towards the brake disc, inserting the insertion rod 15 into the positioning hole of the brake disc. The chuck 17 is then released from the brake disc, and the annular plate 16 moves the brake disc to the top of the arc-shaped support seat 45. At this time, the third hydraulic cylinder 42 is activated. The telescopic end of the third hydraulic cylinder 42 moves the connecting rod 46 down, causing the arc-shaped clamping plate 50 to contact the outer wall of the brake disc. Then, the electric push rod 19 is closed, causing the annular plate 16 to move back to its original position. When the arc-shaped clamping plate 50 presses down on the brake disc, the brake disc will cause the arc-shaped support seat 45 to descend. At this time, because the support plate 53 has an arc-shaped groove, the bottom of the brake disc is stuck in the arc-shaped groove. Then, the fourth motor 44 is activated. The output shaft drives the fourth gear 57 to rotate, and through the third gear 47 drives the connecting rod 46 to rotate. The connecting rod 46 drives the brake disc to rotate 180 degrees through the arc-shaped clamp 50. When the brake disc rotates, the rotating seat 54 also rotates. After the flipping is completed, the fourth hydraulic cylinders 43 on both sides are activated. The extension and retraction ends of the fourth hydraulic cylinders 43 drive the moving trapezoidal block 52 to move towards the arc-shaped support seat 45. At this time, the third hydraulic cylinder 42 retracts, driving the arc-shaped clamp 50 to move upward. At the same time, the two fourth hydraulic cylinders 43 drive the arc-shaped support seat 45 to rise through the moving trapezoidal block 52. The arc-shaped support seat 45 lifts the brake disc, making the brake disc away from the arc-shaped groove. Then the transfer assembly is activated again, inserting the insertion rod 15 into the positioning hole, and transporting the flipped brake disc onto the chuck 17 and fixing it.

[0072] Fourth embodiment:

[0073] This embodiment provides a method for machining a wind turbine brake disc, including the following steps:

[0074] S1: Place the four wind turbine brake discs onto the four chucks 17 respectively and fix them in place, ensuring that the clamping is secure;

[0076] S3: Start the third motor 18, so that the chuck 17 drives the brake disc 14 to rotate and perform cutting. The tool moves along the friction surface of the brake disc to remove the surface wear layer, cracks or uneven parts.

[0077] S4: After one brake disc 14 is cut, continue cutting the next brake disc 14;

[0078] S5: After processing is completed, turn off the turntable 8 and the third motor 18. After the equipment has completely stopped, release the chuck 17 and smoothly remove the brake disc from the worktable.

[0079] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
