Description

TECHNICAL FIELD

[0001] The utility model relates to the field of wind power technology, in particular to a friction plate dismounting tool. BACKGROUND

[0002] In the yaw system of a wind turbine, the friction plate is combined with the output shaft of the yaw motor, and precise positioning and locking of the wind turbine nacelle are achieved through friction. However, as the equipment is operated for a long time, the friction plate may be worn or damaged, and needs to be checked and replaced regularly.

[0003] However, the traditional dismounting and mounting technology of the friction plate on the output shaft of the yaw motor of the wind turbine is usually dependent on manual operation, which not only takes time and effort, but also is prone to inaccurate installation when operating in a narrow space, and due to the complex structure of the output shaft and the friction plate, manual operation may cause uneven force application, increasing the risk of damage to the friction plate or the output shaft.

[0004] The above information disclosed in the background of the present application is only for understanding the background of the concept of the present application, and does not indicate or imply that it contains prior art information. SUMMARY

[0005] Therefore, it is necessary to provide a friction plate dismounting tool to solve the above problems.

[0006] A friction plate dismounting tool for dismounting the friction plate of the yaw motor of a wind turbine, the friction plate dismounting tool comprising a dismounting device, the dismounting device comprising:

[0007] a screw rod for rotatably abutting to the top end of the output shaft of the yaw motor;

[0008] a bracket having a threaded hole, the bracket being sleeved on the screw rod and threadedly connected with the screw rod through the threaded hole;

[0009] a plurality of clamping jaws connected with the bracket along the circumference of the threaded hole, each clamping jaw having a fixed end and a dismounting end away from each other, the fixed ends of the plurality of clamping jaws being connected with the bracket and spacedly distributed along the circumference of the threaded hole, and the dismounting ends being used for spacedly clamping to the circumference of the friction plate;

[0010] wherein the screw rod is arranged to be rotatable under external force and to drive the bracket to move up and down along the axial direction of the screw rod, so that the dismounting ends of the clamping jaws are pulled out from the friction plate sleeved on the output shaft under the driving of the bracket.

[0011] The friction plate dismounting tool has at least the following beneficial effects: the threaded connection between the screw rod and the support enables the support to stably ascend or descend along the screw rod under external force, thereby driving the multiple clamping jaws to move synchronously. This design not only ensures the uniformity of force applied to the friction plate during dismounting, thereby avoiding damage to the friction plate caused by uneven force in the traditional method, but also significantly improves the dismounting efficiency. The reasonable distribution and design of the clamping jaws enable the clamping jaws to stably clamp the periphery of the friction plate, thereby ensuring that the friction plate will not slip or be damaged during dismounting. In addition, the friction plate dismounting tool has simple structure and convenient operation, and has good universality and practicality, greatly simplifies the maintenance process of the friction plate of the yaw motor of the wind turbine, reduces the maintenance cost and time, and realizes efficient and safe dismounting of the friction plate of the yaw motor of the wind turbine.

[0012] In some embodiments, the support includes a main body and multiple support portions, the main body is provided with the threaded hole, the main body is sleeved on the screw rod through the threaded hole and is threadedly connected with the screw rod, and the multiple support portions are connected to the outer circumferential surface of the main body in a circumferential direction. The fixed end of each clamping jaw is connected with one support portion, and the fixed end can move relative to the support portion under external force to adjust the distance between the clamping jaw and the screw rod. The combination of the main body and the multiple support portions enhances the stability and adaptability of the entire device. The threaded hole provided on the main body is not only used for threaded connection with the screw rod, but also provides a flexible connection platform through the multiple circumferentially spaced support portions, so that the fixed end of each clamping jaw can be connected with the support portion. Such a design allows the fixed end of each clamping jaw to be adjusted relative to the support portion under external force, thereby flexibly changing the distance between the clamping jaw and the screw rod. This adjustability enables the friction plate dismounting tool to adapt to friction plates of different sizes and shapes, further improving the universality and applicability of the tool. At the same time, by adjusting the position of the clamping jaw, accurate control of the friction plate can be achieved, ensuring uniform distribution of the force applied during dismounting, and further reducing the risk of damage to the friction plate. This design not only improves the convenience and safety of operation, but also provides the possibility for multifunctional application of the friction plate dismounting tool.

[0013] In some embodiments, a hanging hole is formed on each of the fixed ends, each of the fixed ends is sleeved on the support part through the hanging hole, and each of the fixed ends can slide on the support part through the hanging hole under the action of an external force to adjust the distance between the clamping jaw and the screw rod. By designing a hanging hole on the fixed end of each clamping jaw, the flexibility and adjustability of the tooling are further enhanced. The hanging hole allows the fixed end to be sleeved on the support part and to slide along the support part under the action of an external force. This design allows the fixed end of the clamping jaw to conveniently adjust the distance from the screw rod, thereby adapting to different sizes of friction plates. This sliding adjustment mechanism not only simplifies the operation process, but also improves the accuracy and efficiency of the adjustment process. Through the sliding function of the hanging hole, the operator can quickly adjust the position of the clamping jaw, ensuring that the force applied to the friction plate during disassembly is more uniform, reducing the risk of damage to the friction plate due to improper force, and enhancing the application range of the tooling, making it flexible to cope with different specifications of friction plates, further improving the versatility and practicality of the tooling.

[0014] In some embodiments, the support part is designed in a long strip shape extending along the radial direction of the threaded hole. The support part is designed to extend along the radial direction of the threaded hole and in a long strip shape, providing more sliding space for the fixed end of the clamping jaw, making the process of adjusting the distance between the clamping jaw and the screw rod more smooth and accurate. Through this design, the tooling can adapt to a wider range of application scenarios, improving the efficiency of operation and the durability and service life of the device. This improvement enables the tooling to maintain high performance and stable operation effect when handling different specifications and shapes of friction plates.

[0015] In some embodiments, the support part is integrally formed with the main body. Integrally formed means that the support part and the main body are directly formed as a whole during manufacturing, without additional connecting components or welding points, which can significantly improve the overall strength and stability of the structure, reducing weak points or failure points that may be caused by the connection of multiple components, thereby improving the durability and reliability of the device. In addition, this design can simplify the production process and reduce manufacturing costs, as no additional assembly or welding steps are required, making it suitable for applications that require high strength and high precision, especially in situations that require frequent adjustment or bear heavy loads. The combination of the integrally formed support part and the main body not only improves the service life of the product, but also enhances the overall aesthetics and consistency.

[0016] In some embodiments, the support further comprises a locking member detachably connected to the support portion, the locking member being located on the side of the fixed end away from the main body, and the locking member being capable of abutting against the fixed end to limit the sliding of the locking member in the direction away from the main body. In this design, the support improves its functionality and safety by adding a detachable locking member. The locking member is connected to the support portion and located on the side of the fixed end away from the main body. Its main function is to abut against the fixed end, thereby limiting the sliding of the locking member in the direction away from the main body. This design effectively prevents the fixed end of the clamping jaw from coming off the support portion. The detachable design of the locking member provides users with higher convenience in maintenance and adjustment. Users can quickly adjust or replace it according to specific needs, ensuring that the equipment is always in the best working condition.

[0017] In some embodiments, the locking member is a locking screw, and the locking member is threadedly connected to the end of the support portion away from the main body. The threaded connection design allows users to conveniently install and remove the locking screw. This convenience not only facilitates the maintenance and repair of the equipment, but also allows the locking member to be quickly replaced when needed to adapt to different operating requirements or changes in conditions. In addition, the locking screw is located at the end of the support portion away from the main body. This layout optimizes space utilization, allowing most of the structure of the support portion to be the area where the fixed end of the clamping jaw can slide, increasing the adjustment range of the clamping jaw and thus accommodating the disassembly and assembly of more different sizes of friction plates.

[0018] In some embodiments, the disassembly end of each clamping jaw is bent towards the screw rod to form a bayonet, and the bayonet is used to clamp the periphery of the friction plate. The design of the bayonet allows the clamping jaw to be firmly clamped to the periphery of the friction plate. In this way, the clamping jaw can be firmly fixed to the friction plate to prevent sliding or falling during operation. This stable connection improves the reliability and safety of the entire system. The design of the bayonet makes the installation and removal of the clamping jaw more convenient and fast. Users can fix and remove the clamping jaw through simple clamping actions. This convenience greatly reduces the maintenance time of the equipment and improves work efficiency. In addition, the design of the bayonet can also adapt to different thicknesses or shapes of friction plates, providing a certain flexibility. This adaptability allows the equipment to maintain good performance under various operating conditions.

[0019] In some embodiments, the dismounting end is provided with a guide slope on the side facing the socket. When the dismounting end is to be clamped with the friction plate, the guide slope can abut against the side of the friction plate away from the support to guide the clamping of the periphery of the friction plate into the socket. The presence of the guide slope makes it easier and smoother for the friction plate to be clamped with the clamping jaw. When the dismounting end is in contact with the friction plate, the guide slope can effectively guide the periphery of the friction plate into the socket, i.e. the dismounting end can be more easily inserted into the periphery of the side of the friction plate away from the screw rod to complete the clamping of the dismounting end with the friction plate. This guiding action reduces the resistance and friction in the installation process, making the installation process smoother. In addition, the guide slope can also reduce the wear of the friction plate during installation, so that the slope can smoothly guide the friction plate into the socket, thereby prolonging the service life of the friction plate and the clamping jaw.

[0020] In some embodiments, one end of the screw rod is provided with an abutting protrusion for the friction plate to abut against, and the abutting protrusion is in a semispherical shape. The semispherical abutting protrusion provides a smooth contact surface, which can effectively reduce friction and wear when in contact with the friction plate. This smooth contact surface helps to prolong the service life of the friction plate, while protecting the end of the screw rod from damage.

[0021] In some embodiments, the end of the screw rod away from the friction plate is provided with an operating portion for a wrench to be clamped into to operate the rotation of the screw rod. The design of the operating portion makes the installation and dismounting of the screw rod more convenient. By providing a special clamping position for the wrench, the user can more easily apply torque, thereby easily rotating the screw rod. This design reduces the complexity of the operation and improves work efficiency.

[0022] In some embodiments, the friction plate dismounting tool further comprises a mounting sleeve, the mounting sleeve is internally hollowed to form a clearance groove, the mounting sleeve is used to abut to the top of the friction plate pre-fitted on the output shaft of the yaw motor, to extrude the friction plate to slide along the axial direction of the output shaft, and to make the friction plate mesh with the transmission gear on the output shaft of the yaw motor, and the clearance groove is used for the output shaft to extend into. The hollow design of the mounting sleeve and the arrangement of the clearance groove enable it to effectively avoid the output shaft, thereby providing sufficient space during installation. This design ensures that the mounting sleeve can abut to the top of the friction plate smoothly without interfering with the output shaft. Secondly, the mounting sleeve can slide the friction plate along the axial direction of the output shaft by applying pressure, such as knocking the mounting sleeve with another tool. This function enables the friction plate to accurately mesh with the transmission gear on the output shaft of the yaw motor. In this way, the mounting sleeve simplifies the installation process of the friction plate, improves the accuracy and efficiency of installation. In addition, the design of the mounting sleeve also protects the safety of the friction plate and the output shaft during installation. By avoiding direct application of uneven force, the mounting sleeve reduces the risk of damage to the friction plate or the output shaft, thereby prolonging the service life of the equipment. This design also improves the operational convenience of the system. Since the mounting sleeve can quickly and accurately position and install the friction plate, users can more efficiently perform maintenance and replacement work on the equipment. This convenience is particularly important for systems that require frequent maintenance. BRIEF DESCRIPTION OF DRAWINGS

However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model, so the present utility model is not limited by the specific embodiments disclosed below.

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the present application provides a friction plate 40 dismounting tool for dismounting the friction plate 40 of the yaw motor of a wind turbine generator, the friction plate 40 dismounting tool comprising a dismounting device 10, the dismounting device 10 comprising a screw rod 100, a support 200 and a plurality of clamping jaws 300. The screw rod 100 is used to rotatably abut to the top end of the output shaft 20 of the yaw motor; the support 200 is provided with a threaded hole 211, the support 200 is sleeved on the screw rod 100 through the threaded hole 211 and is threadedly connected with the screw rod 100; a plurality of the clamping jaws 300 are connected with the support 200 along the circumference of the threaded hole 211, each of the clamping jaws 300 has a fixed end 310 and a dismounting end 320 which are away from each other, a plurality of the fixed ends 310 are connected with the support 200 and are distributed along the circumference of the threaded hole 211, and a plurality of the dismounting ends 320 are used for being spacedly connected to the circumferential edge of the friction plate 40; wherein the screw rod 100 is arranged to be able to rotate under the action of external force and drive the support 200 to make lifting movement along the axial direction of the screw rod 100, so that the dismounting end 320 of the clamping jaw 300 is driven by the support 200 to pull out the friction plate 40 sleeved on the output shaft 20.

[0033] The friction plate 40 dismounting tool has at least the following beneficial effects: the threaded connection between the screw rod 100 and the support 200 enables the support 200 to stably ascend and descend along the screw rod 100 under external force, thereby driving the plurality of clamping jaws 300 to move synchronously. This design not only ensures the uniformity of the force applied to the friction plate 40 during dismounting, thereby avoiding damage to the friction plate 40 caused by uneven force in traditional methods, but also significantly improves the dismounting efficiency. The reasonable distribution and design of the clamping jaws 300 enable them to stably clamp the periphery of the friction plate 40, thereby ensuring that the friction plate 40 will not slip or be damaged during dismounting. In addition, the friction plate 40 dismounting tool has simple structure, convenient operation, good universality and practicality, greatly simplifies the maintenance process of the friction plate 40 of the yaw motor of the wind turbine, reduces the maintenance cost and time, and realizes efficient and safe dismounting of the friction plate 40 of the yaw motor of the wind turbine.

[0034] Specifically, as Figure 1 , Figure 2 and Figure 3 , in some embodiments, the support 200 includes a main body 210 and a plurality of support portions 220, the main body 210 is provided with the threaded hole 211, the main body 210 is sleeved on the screw rod 100 through the threaded hole 211 and is threadedly connected with the screw rod 100, and the plurality of support portions 220 are connected to the outer circumferential surface of the main body 210 at equal intervals along the circumference of the threaded hole 211. The fixed end 310 of each clamping jaw 300 is connected with one support portion 220, and the fixed end 310 can move relative to the support portion 220 under external force to adjust the distance between the clamping jaw 300 and the screw rod 100. Through the combined structure of the main body 210 and the plurality of support portions 220, the stability and adaptability of the entire device are enhanced. The threaded hole 211 provided on the main body 210 is not only used for threaded connection with the screw rod 100, but also provides a flexible connection platform through the plurality of support portions 220 distributed at equal intervals along the circumference, so that the fixed end 310 of each clamping jaw 300 can be connected with the support portion 220. Such a design allows the fixed end 310 of each clamping jaw 300 to be adjusted relative to the support portion 220 under external force, thereby flexibly changing the distance between the clamping jaw 300 and the screw rod 100. This adjustability enables the friction plate 40 dismounting tool to adapt to friction plates 40 of different sizes and shapes, further improving the universality and applicability of the tool. At the same time, by adjusting the position of the clamping jaw 300, precise control of the friction plate 40 can be achieved, ensuring that the force applied during dismounting is evenly distributed, thereby further reducing the risk of damage to the friction plate 40. This design not only improves the convenience and safety of operation, but also provides the possibility for multifunctional application of the friction plate 40 dismounting tool.

[0035] More specifically, as Figure 3As shown, in some embodiments, each fixed end 310 is provided with a hanging hole 311. Each fixed end 310 is mounted on one of the support portions 220 through the hanging hole 311. Each fixed end 310 can slide on the support portion 220 through the hanging hole 311 under the action of an external force to adjust the distance between the clamping jaw 300 and the screw 100. The design of the hanging hole 311 on the fixed end 310 of each clamping jaw 300 further enhances the flexibility and adjustability of the tooling. The hanging hole 311 allows the fixed end 310 to be mounted on the support portion 220 and to slide along the support portion 220 under the action of an external force. This design allows the fixed end 310 of the clamping jaw 300 to easily adjust the distance from the screw 100 to accommodate friction plates 40 of varying sizes. This sliding adjustment mechanism not only simplifies the operation process but also improves the accuracy and efficiency of the adjustment process. Through the sliding function of the hanging hole 311, the operator can quickly adjust the position of the clamp 300 to ensure that the force applied to the friction plate 40 is more uniform during the disassembly and assembly process, reducing the risk of damage to the friction plate 40 due to improper force, and enhancing the applicability of the tooling, enabling it to flexibly cope with friction plates 40 of different specifications, further improving the versatility and practicality of the tooling.

[0036] More specifically, Figures 1 to 4 As shown, in some embodiments, the support portion 220 is configured to extend radially along the threaded hole 211 and be in the shape of an elongated strip. The support portion 220 is designed to extend radially along the threaded hole 211 and be in the shape of an elongated strip, providing more sliding space for the fixed end 310 of the clamping jaw 300, making the process of adjusting the distance between the clamping jaw 300 and the screw 100 smoother and more precise. This design allows the tool to adapt to a wider range of application scenarios, improving not only operational efficiency but also the durability and service life of the device. This improvement enables the tool to maintain efficient performance and stable operation when handling friction plates 40 of different specifications and shapes.

[0037] More specifically, in some embodiments, the support portion 220 is integrally formed with the main body 210. Integral molding means that the support portion 220 and the main body 210 are directly formed into a whole during the manufacturing process, without additional connecting parts or welding points, which can significantly improve the overall strength and stability of the structure, reduce the weaknesses or failure points that may arise due to the connection of multiple parts, and thus improve the durability and reliability of the device. In addition, this design can also simplify the production process and reduce manufacturing costs, because no additional assembly or welding steps are required. It is suitable for application scenarios that require high strength and high precision, especially when frequent adjustments or heavy loads are required. The combination of the integrally molded support portion 220 and the main body 210 not only improves the service life of the product, but also improves the overall aesthetics and consistency.

[0038] Referring to Figure 3 In some embodiments, the support 200 further comprises a locking member 230 detachably connected to the support portion 220, the locking member 230 being located on the side of the fixed end 310 away from the main body 210, and the locking member 230 being capable of abutting against the fixed end 310 to limit the sliding of the locking member 230 in the direction away from the main body 210. In this design, the support 200 improves its functionality and safety by adding a detachable locking member 230. The locking member 230 is connected to the support portion 220 and located on the side of the fixed end 310 away from the main body 210. Its main function is to abut against the fixed end 310, thereby limiting the sliding of the locking member 230 in the direction away from the main body 210. This design effectively prevents the fixed end 310 of the clamping jaw 300 from coming off the support portion 220. The detachable design of the locking member 230 provides users with higher convenience in maintenance and adjustment. Users can quickly adjust or replace it according to specific needs, ensuring that the equipment is always in the best working condition.

[0039] Specifically, in some embodiments, the locking member 230 is a locking screw, and the locking member 230 is threadedly connected to the end of the support portion 220 away from the main body 210. The threaded connection design allows users to conveniently install and remove the locking screw. This convenience not only helps in the maintenance and repair of the equipment, but also allows the locking member 230 to be quickly replaced when needed, to adapt to different operating requirements or changes in conditions. In addition, the locking screw is located at the end of the support portion 220 away from the main body 210. This layout optimizes the use of space, so that most of the structure of the support portion 220 is the area where the fixed end 310 of the clamping jaw 300 can slide, increasing the adjustment range of the clamping jaw 300, so that it can adapt to the disassembly and assembly requirements of more different sizes of friction plates 40.

[0040] Referring to Figure 1 , Figure 2 and Figure 3In some embodiments, the dismounting end 320 of each jaw 300 is bent towards the screw rod 100 to form a bayonet 330 for clamping to the periphery of the friction plate 40. The design of the bayonet 330 allows the jaw 300 to be securely clamped to the periphery of the friction plate 40. In this way, the jaw 300 can be firmly fixed to the friction plate 40, preventing it from slipping or falling off during operation. This stable connection improves the reliability and safety of the entire system. The design of the bayonet 330 makes it easier and faster to install and remove the jaw 300. Users can easily clamp and remove the jaw 300 through simple clamping actions, which greatly reduces the maintenance time of the equipment and improves work efficiency. In addition, the design of the bayonet 330 can also adapt to friction plates 40 of different thicknesses or shapes, providing a certain degree of flexibility. This adaptability allows the equipment to maintain good performance under various operating conditions.

[0041] Specifically, as shown in Figures 1 to 4 In some embodiments, the dismounting end 320 is provided with a guide slope 321 on the side facing the bayonet 330. When the dismounting end 320 is to be clamped with the friction plate 40, the guide slope 321 can abut the side of the friction plate 40 facing away from the main body 210 to guide the periphery of the friction plate 40 into the bayonet 330. The presence of the guide slope 321 makes it easier and smoother for the friction plate 40 to be clamped with the jaw 300. When the dismounting end 320 contacts the friction plate 40, the guide slope 321 can effectively guide the periphery of the friction plate 40 into the bayonet 330, i.e. the dismounting end 320 can more easily be inserted into the periphery of the side of the friction plate 40 facing away from the screw rod 100, completing the clamping of the dismounting end 320 with the friction plate 40. This guiding action reduces resistance and friction during installation, making the installation process smoother. In addition, the guide slope 321 can also reduce the wear of the friction plate 40 during installation, allowing the slope to smoothly guide the friction plate 40 into the bayonet 330, thereby prolonging the service life of the friction plate 40 and the jaw 300.

[0042] Please refer to Figure 2 In some embodiments, one end of the screw rod 100 is provided with an abutting protrusion 110 for the friction plate 40 to abut, and the abutting protrusion 110 is in the shape of a hemisphere. The hemispherical abutting protrusion 110 provides a smooth contact surface, which can effectively reduce friction and wear when in contact with the friction plate 40. This smooth contact surface helps to prolong the service life of the friction plate 40 and protects the end of the screw rod 100 from damage.

[0043] Specifically, as shown in Figures 1 to 4As shown, in some embodiments, the screw rod 100 is provided with an operating portion 120 at one end away from the friction plate 40, which is used for a wrench to be clamped in to operate the screw rod 100 to rotate. The design of the operating portion 120 makes the installation and disassembly of the screw rod 100 more convenient. By providing a special clamping position for the wrench, the user can more easily exert torque, thus easily rotating the screw rod 100. This design reduces the complexity of operation and improves work efficiency.

[0044] Please refer to Figure 5 In some embodiments, the friction plate 40 dismounting tool further comprises a mounting sleeve 50, which is hollow inside and formed with a clearance groove 51, and is used for abutting to the top of the friction plate 40 pre-fitted on the output shaft 20 of the yaw motor, so as to extrude the friction plate 40 to slide along the axial direction of the output shaft 20 and make the friction plate 40 engage with the transmission gear 30 on the output shaft 20 of the yaw motor, and the clearance groove 51 is used for the output shaft 20 to extend into. The hollow design of the mounting sleeve 50 and the provision of the clearance groove 51 enable it to effectively avoid the output shaft 20, thus providing sufficient space during installation. This design ensures that the mounting sleeve 50 can abut to the top of the friction plate 40 smoothly without interfering with the output shaft 20. Secondly, the mounting sleeve 50 can slide the friction plate 40 in the axial direction of the output shaft 20 by applying pressure, such as knocking the mounting sleeve 50 with another tool. This function enables the friction plate 40 to engage with the transmission gear 30 on the output shaft 20 of the yaw motor accurately. In this way, the mounting sleeve 50 simplifies the installation process of the friction plate 40 and improves the accuracy and efficiency of installation. In addition, the design of the mounting sleeve 50 also protects the safety of the friction plate 40 and the output shaft 20 during installation. By avoiding direct application of uneven force, the mounting sleeve 50 reduces the risk of damage to the friction plate 40 or the output shaft 20, thus prolonging the service life of the equipment. This design also improves the operational convenience of the system. Since the mounting sleeve 50 can quickly and accurately position and install the friction plate 40, the user can more efficiently perform maintenance and replacement work on the equipment. This convenience is particularly important for systems that require frequent maintenance.
