Description

Technical Field

[0001] This invention relates to wind power equipment technology, specifically to a linkage bracket for a wind power coupling. Background Technology

[0002] In wind turbine generator sets, the wind turbine coupling is a key component used to connect the high-speed shaft of the gearbox and the motor shaft. The connection stability of the wind turbine coupling will determine many key factors such as wind energy conversion efficiency, unit service life and safety.

[0003] During operation, wind turbine couplings are subject to various environmental factors, including manufacturing and installation errors, load deformation and thermal expansion, foundation loosening and wear, improper assembly of the gearbox and generator, relative movement of components, and impact loads caused by unstable wind speeds. These factors can lead to radial displacement (offset perpendicular to the axis) and axial displacement (movement along the axis). When these displacements occur, the wind turbine coupling will experience increased vibration and noise, accelerated wear of bearings and components, decreased transmission efficiency, and the generation of parasitic currents (conducted to the gearbox through the coupling). These factors can result in increased mechanical fatigue of the wind turbine coupling, reduced equipment stability, flexural deformation of the input or output shaft of the wind turbine, shortened equipment life, and increased risk of failure.

[0004] Based on this, the present invention aims to provide a linkage bracket for wind turbine couplings, which can better support and limit the wind turbine couplings when abnormal radial and axial displacements occur, eliminate or mitigate the impact and risks of wind turbine coupling displacement, and avoid excessive displacement of the wind turbine couplings leading to corresponding efficiency, damage or safety problems in the wind turbine generator set and the entire wind turbine generator set. Summary of the Invention

[0008] Based on the above technical solution, a first limiting post is also provided at the middle position of the bottom of the countersunk hole, and a first elastic pressure sensor protruding from the upper end surface of the first limiting post is provided in the middle of the first limiting post.

[0009] Based on the above technical solution, it also includes two sets of lifting support components, which are symmetrically arranged on the other two sides of the floating support component. The lifting support component includes a platform and a secondary support. The secondary supports on both sides are located below both ends of the wind turbine coupling and are spaced apart from the wind turbine coupling. A swing rod is connected to the bottom of the secondary support, and one end of the swing rod is connected to the linkage component. An elastic support rod and a column are arranged sequentially on the platform. The elastic support rod is sleeved on the other end of the swing rod, and the column is connected to the swing rod between the elastic support rod and the linkage component through a universal joint.

[0010] Based on the above technical solution, the top of the support platform is provided with an installation hole, a second elastic element is provided in the installation hole, the elastic support rod is pressed against the second elastic element, and the diameter of the installation hole is larger than the outer diameter of the elastic support rod; a second limiting post is also provided at the bottom of the installation hole, and a second elastic pressure sensor protruding from the upper end face of the second limiting post is provided in the middle of the second limiting post.

[0011] Based on the above technical solution, it also includes a coupling axial support assembly; the coupling axial support assembly includes a horizontal sliding rod, a support column fixed on the horizontal sliding rod, and a limiting member fixed to the top of the support column. The horizontal sliding rod is sleeved on the end of the swing rod that is hinged to the elastic support rod, and the horizontal sliding rod can be adjusted and locked with the swing rod. The limiting member is provided with a limiting hole and an axial support that can extend into the limiting hole. The part of the axial support extending out of the limiting hole faces the end face of the wind turbine coupling and is spaced apart from the end face of the wind turbine coupling. A third elastic member is provided in the limiting hole, and the part of the axial support located in the limiting hole is pressed against the third elastic member. A third limiting post is also provided at the bottom of the limiting hole, and a third elastic pressure sensor protruding from the upper end face of the third limiting post is provided in the middle of the third limiting post.

[0012] Based on the above technical solution, both the main support and the auxiliary support are arc-shaped structures, and the end faces of the main support, the auxiliary support and the axial support facing the wind turbine coupling are provided with several balls protruding from the corresponding end faces.

[0013] Based on the above technical solution, the linkage component includes a first linkage rod, a second linkage rod, and a linkage plate; the two sides of the main support are rotatably connected to the first linkage rod and the second linkage rod respectively, and the lower ends of the two rotating supports are rotatably connected to the first linkage rod or the second linkage rod on the same side respectively; two linkage plates are provided and are respectively fixed to the same side end of the first linkage rod and the second linkage rod, and a hinge shaft is provided in the middle of the outer side of each of the two linkage plates, and the hinge shaft is respectively hinged to the swing rods on both sides.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention is used as a whole to support wind turbine couplings. When the wind turbine coupling is running, the floating support assembly can rise and fall or swing left and right based on the state of the wind turbine coupling, thereby adapting to small-amplitude vibrations and / or swings of the wind turbine coupling within a reasonable range. It can also buffer the loads (such as impact loads) on the wind turbine coupling, providing flexible support without affecting the operation of the wind turbine coupling, and adjusting the support in real time according to the state of the wind turbine coupling, significantly improving the support and adaptation effect. At the same time, when the state of the wind turbine coupling is abnormal, such as large vibration and swing amplitudes or radial displacement, the floating support assembly synchronously supports the coupling through the linkage assembly. The rotating support assembly provides radial support to the wind turbine coupling, thereby buffering abnormal vibrations and reducing sway amplitude, maintaining the wind turbine coupling within a reasonable range of operation. Simultaneously, when radial displacement occurs in the wind turbine coupling, the rotating support assembly effectively prevents further displacement, limits excessive displacement, and maintains its operation within a reasonable space. This eliminates or mitigates the impact and risks of wind turbine coupling displacement, preventing excessive displacement of the wind turbine coupling and the entire wind turbine generator set from experiencing corresponding efficiency, damage, or safety issues. This achieves effective support for the wind turbine coupling and allows for restriction and adjustment in case of abnormalities, enhancing overall practicality and safety.

Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0028] Please refer to the following: Figure 1 , Figure 2 and Figure 3This invention provides a linkage support for a wind turbine coupling, comprising a lifting base 1, a floating support assembly 2 and symmetrically arranged rotating support assemblies 3 on both sides of the upper center of the lifting base 1; the floating support assembly 2 includes a floating base 4 and a main support 5 disposed within the floating base 4, the top of the main support 5 contacting the circumferential surface of the wind turbine coupling a and being able to rise and fall and / or swing left and right under the action of the floating base 4; the rotating support assembly 3 includes a lifting bracket 6 and a rotating support 7 rotatably connected to the lifting end of the lifting bracket 6, the rotating support 7 initially spaced apart from the circumferential surface of the wind turbine coupling a; and a linkage assembly 8, wherein the main support 5 and the rotating supports 7 on both sides are connected by the linkage assembly 8, and when the main support 5 rises and falls and / or swings left and right, the rotating supports 7 on both sides are linked under the action of the linkage assembly 8 and can contact the circumferential surface of the wind turbine coupling a for support.

[0029] In practical applications, the linkage bracket of this embodiment is fixed below the wind turbine coupling a. It can be fixed to the corresponding horizontal infrastructure (such as the positioning base of the output or input system in the wind turbine generator set) through the lifting base 1. The height of the floating support component 2 and the rotating support component 3 can be adjusted by lifting the lifting base 1. Specifically, after the floating support component 2 is adjusted as a whole, its main support 5 abuts against and bears the force of the circumferential surface at the lower middle part of the wind turbine coupling. When necessary, the lifting bracket 6 can also adjust the height of the rotating support 7, adjust the support height and support force of the main support 5, and adjust the distance between it and the circumferential surface of the wind turbine coupling to ensure that the distance between the rotating support 7 and the circumferential surface of the wind turbine coupling is set (3~8mm) in the initial state.

[0030] Furthermore, during normal operation, the wind turbine coupling can be flexibly supported and limited by the floating support assembly 2. The main support 5, under the action of the floating base 4, can autonomously rise and / or swing left and right, thus adapting to the vibration and swing of the wind turbine coupling within a reasonable range and meeting its reasonable spatial change requirements. However, when the wind turbine coupling is in an abnormal state and the spatial change exceeds a certain dimensional range, the main support 5 will simultaneously rise and / or swing left and right, adapting to the spatial requirements of its changing state while also providing a certain buffering effect on the wind turbine coupling, and simultaneously limiting it to a certain extent, allowing the wind turbine coupling to change spatially within a reasonable range, or constraining it back to a reasonable hollow range. At the same time, the main support 5... When the main support 5 is raised, lowered, and / or swayed left and right, its synchronization will also drive the rotating supports 7 on both sides to move together under the action of the linkage component 8. Since there is an initial gap between the rotating supports 7 on both sides and the wind turbine coupling, when the wind turbine coupling changes space within a reasonable range, the rotating supports 7 do not contact the wind turbine coupling. However, once the space of the wind turbine coupling changes abnormally, the main support 5 raises, lowers, and / or sways left and right, and the rotating supports 7 can contact the circumferential surface of the wind turbine coupling simultaneously or separately when the main support 5 is raised, lowered, and / or sways left and right, thereby limiting and supporting it. Since its contact with the circumferential surface of the wind turbine coupling is based on the linkage of the main support 5, it will not rigidly restrict the state change of the wind turbine coupling. Thus, the following linkage structure is formed as a whole:

[0031] When the wind turbine coupling is in normal operation, its physical state is stable, and the vibration, sway, and displacement it generates are all within a reasonable range. Therefore, the lifting and / or left-right swaying amplitude of the main support 5 is also within a reasonable range to adapt to the reasonable spatial change requirements of the wind turbine coupling and provide adaptive flexible support and limit. At this time, although the rotating support 7 lifts and / or sways left and right with the main support 5 under the action of the linkage component 8, based on the reasonable lifting and / or left-right swaying amplitude of the main support 5 and the gap setting between the rotating supports 7 on both sides and the wind turbine coupling, the rotating supports 7 on both sides will basically not contact the wind turbine coupling, thus avoiding contact with the wind turbine coupling and affecting its normal operation.

[0032] When a wind turbine coupling is in an abnormal operating state, its physical state is relatively unstable, and the resulting vibrations, swaying, and displacements may exceed reasonable limits. Consequently, the lifting and / or left-right swaying amplitudes of the main support 5 will also exceed reasonable limits, leading to a decrease or failure in the support and limiting effect of the main support 5. At this time, the rotation amplitude of the rotating supports 7 on both sides increases under the action of the linkage component 8, thus contacting the circumferential surface of the wind turbine coupling a. Together with the main support 5, they provide support and limiting for the wind turbine coupling. During this process, based on the changes in the state of the wind turbine coupling, the main support 5 and the rotating supports 7 on both sides synchronously change their support direction, angle, and support force, thus preventing excessive damage to the wind turbine coupling. Simultaneously, they can limit the aggravation of abnormalities in the wind turbine coupling and buffer the unstable loads it receives, providing excellent protection for the entire coupling and the wind turbine generator set.

[0033] Thus, this embodiment, through the reasonable design of the floating support component 2 and the rotating support component 3, can provide flexible support and limiting based on the needs of the wind turbine coupling. It can also make adaptive state adjustments in sync with changes in the spatial state of the wind turbine coupling, adapting to and protecting the wind turbine coupling and even the entire wind turbine generator set. It can also buffer the load on the wind turbine coupling and limit and guide the wind turbine coupling within a reasonable space range, preventing its abnormal state from being further aggravated. The overall superiority is significant.

[0034] It should be noted that the abnormal condition of the aforementioned wind turbine couplings includes, but is not limited to, the following situations:

[0035] 1. Settlement issues caused the wind turbine couplings to shift downwards.

[0036] During application, depending on the application environment (areas prone to settlement), equipment installation (such as loose foundations and wear), the input or output system of the wind turbine coupling may experience the same or different degrees of settlement, causing the wind turbine coupling to sink as a whole or sink non-horizontally (i.e., the two ends of the wind turbine coupling sink at different heights). This results in the wind turbine coupling sinking beyond the reasonable range, which increases the pressure on the main support 5. During vibration and swaying, its impact on the main support 5 will also increase, as will the downward pressure height and the left and right swaying amplitude of the main support 5.

[0037] 2. Vibration and oscillation of wind turbine couplings caused by irregular load impacts

[0038] During application, due to the impact load caused by unstable wind speed, the wind turbine coupling may experience irregular vibrations and swaying of varying durations. At this time, the main support 5 will generate a large lifting and swaying amplitude.

[0039] 3. Radial displacement of wind turbine coupling

[0040] In application, wind turbine couplings may experience radial displacement due to various factors as described in the background art, including vertical diameter displacement (generally downward displacement) and / or left and right radial displacement. When the displacement is too large and exceeds the reasonable range, the adjustment range of the main support 5 and / or the rotating support 7 will increase.

[0041] 4. Other factors

[0042] In application, when there are abnormal situations such as coupling slippage, failure of connection between the two shafts, or external factors (such as earthquakes), the wind power coupling may also be affected and exhibit abnormal vibration, swaying, and radial displacement.

[0043] As a specific implementation method, such as Figure 2 , Figure 3 As shown, the floating base 4 has a countersunk hole 9 in the middle. The floating base 4 also has horizontally penetrating swing notches 10 on both sides of the countersunk hole 9, which are connected to the countersunk hole 9. Each swing notch 10 on both sides is provided with a lifting baffle 11. The support rod at the bottom of the main support 5 is vertically installed in the countersunk hole 9, and a first elastic element 12 connected to the support rod is also provided at the bottom of the countersunk hole 9. Two pressure rods 13 are symmetrically arranged on the support rod. The two pressure rods 13 are respectively located above the lifting baffles 11 on both sides to squeeze and drive the lifting baffles 11 to rise and fall. The support rod and the lifting baffles 11 on both sides are spaced apart to form a swing gap for the main support 5 to swing left and right.

[0044] In application, the main support 5 can be vertically raised and lowered under the elastic force of the first elastic element 12, providing flexible support for the upper wind turbine coupling and responding synchronously to the wind turbine coupling's status in real time, thus meeting the space change requirements of the wind turbine coupling's own status. At the same time, based on the existence of the swing gap, the main support 5 can tilt within the countersunk hole 9 and towards the swing notch 10 on one side, and swing within the swing gap (2-5mm) under the obstruction of the lifting baffle 11. This allows it to tilt and swing to the corresponding side when the wind turbine coupling swings or deviates, adapting to the changes in the wind turbine coupling's status and achieving a real-time synchronous support effect. When the wind turbine coupling is abnormal, the main support 5 will press down or swing more, at which point the pressure rod 13 can squeeze the lifting baffle 11 to press it down, thereby releasing the restriction of the lifting baffle 11 and allowing for large-scale lifting and / or left and right swinging, which can drive the rotating support 7 to rotate significantly, realizing the linkage support of the main support 5 and the rotating support 7.

[0045] As one specific implementation scheme, a first limiting post 14 is also provided at the middle position of the bottom of the countersunk hole 9, and a first elastic pressure sensor 15 protruding from the upper end face of the first limiting post 14 is provided in the middle of the first limiting post 14. In application, if the vibration, swaying, or radial displacement caused by the abnormal state of the wind turbine coupling exceeds a certain threshold range, the support rod will descend and directly squeeze the first elastic pressure sensor 15. After being subjected to force, the first elastic pressure sensor 15 can send a signal to the corresponding control system or alarm system to trigger an alarm, so as to facilitate timely equipment repair. At the same time, the support rod will not move further down under the restriction of the first limiting post 14, thereby ensuring that the height of the main support 5 will not decrease, so as to ensure that the wind turbine coupling can maintain its original operation and avoid the expansion of damage, and also to buy time for subsequent equipment maintenance.

[0046] When a wind turbine coupling experiences radial displacement during implementation, it may be due to the coupling not settling horizontally. As a result, the two ends of the coupling will move downwards at different heights, causing the entire coupling to be unable to run horizontally. This can lead to fatigue wear, breakage of the input shaft, and other serious damage to the service life and safety of the wind turbine coupling and the entire wind turbine generator set.

[0047] Based on this, such as Figure 4 As shown, the linkage support in this embodiment also includes two sets of lifting support components 16, which are symmetrically arranged on the other two sides of the floating support component 2. Each lifting support component 16 includes a platform 17 and a secondary support 18. The secondary supports 18 on both sides are located below the two ends of the wind turbine coupling and are spaced apart from the wind turbine coupling. A swing rod 19 is connected to the bottom of the secondary support 18, and one end of the swing rod 19 is connected to the linkage component 8. An elastic support rod 20 and a column 21 are arranged sequentially on the platform 17. The elastic support rod 20 is sleeved on the other end of the swing rod 19, and the column 21 is connected to the swing rod 19 between the elastic support rod 20 and the linkage component 8 through a universal joint.

[0048] In application, under normal conditions, when the main support 5 rises and / or swings left and right, it drives the swing rod 19 to move through the linkage component 8. Under the hinge action of the column 21, the swing rod 19, driven by the linkage component 8, synchronously rises and / or swings left and right at the end where the secondary support 18 is located, achieving a further linkage effect. Since the secondary support 18 is located below both ends of the wind turbine coupling and is spaced apart from the wind turbine coupling by 3~8mm, the secondary support 18 will not contact the wind turbine coupling. However, under abnormal conditions (especially when the wind turbine coupling sinks), the rising and / or swinging amplitude of the main support 5 increases, and the rising and / or swinging amplitude of the secondary support 18, driven by the linkage component 8, increases. This synchronously supports one or both ends of the coupling, thus providing flexible support and limiting the coupling as a whole, buffering the vibration, swinging or load impact of the wind turbine coupling, and limiting its displacement and downward movement.

[0049] It should be noted that if the wind turbine coupling experiences significant non-horizontal settlement, initially the main support 5 will be unloaded or subjected to minimal force, while the end with greater settlement height may directly contact the secondary support 18 and, in the opposite direction, drive the main support 5 upward through the linkage assembly to support the coupling. Thus, the two complement each other and achieve adaptive state linkage.

[0050] As one of the specific implementation schemes, the top of the support platform 17 is provided with a mounting hole 22, and a second elastic element 23 is provided in the mounting hole 22. The elastic support rod 20 is pressed against the second elastic element 23, and the diameter of the mounting hole 22 is larger than the outer diameter of the elastic support rod 20. A second limiting post 24 is also provided at the bottom of the mounting hole 22, and a second elastic pressure sensor 25 protruding from the upper end face of the second limiting post 24 is provided in the middle of the second limiting post 24.

[0051] In application, a large downward displacement of the coupling may endanger the safety of the coupling, input shaft, output shaft, and the entire unit. Therefore, in this embodiment, the second elastic element 23 provides flexible support to the elastic support rod 20, giving it a certain degree of flexibility. Since the diameter of the mounting hole 22 is larger than the outer diameter of the elastic support rod 20, it can adapt to the changing state of the wind turbine coupling within a certain range. At the same time, when one end of the wind turbine coupling moves downward beyond a certain range, it will press down on the elastic support rod 20 and the second elastic pressure sensor 25. The second elastic pressure sensor 25 will send a contact signal to the external control system or alarm system. Meanwhile, the second limiting post 24 provides rigid support to the elastic support rod 20 and restricts its downward movement, ensuring that the wind turbine coupling will not move further and buying time for equipment maintenance.

[0052] During implementation, wind turbine couplings may also experience axial displacement, that is, axial displacement of the coupling along the input or output shaft. This situation can lead to transmission failure, accelerated wear of the coupling, increased vibration of the coupling, etc., which will also endanger the service life and safety of the wind turbine coupling and the entire wind turbine generator set.

[0053] Based on this, such as Figure 4 , Figure 5 As shown, the linkage bracket in this embodiment also includes a coupling axial support assembly 26; the coupling axial support assembly 26 includes a horizontal sliding rod 27, a support column 28 fixed on the horizontal sliding rod 27, and a limiting member 29 fixed to the top of the support column 28. The horizontal sliding rod 27 is sleeved on the end of the swing rod 19 that is hinged to the elastic support rod 20, and the horizontal sliding rod 27 can be adjusted to the sleeve depth with the swing rod 19 and locked; the limiting member 29 is provided with a limiting hole 30 and an extendable part. An axial support 31 is provided inside the limiting hole 30. The portion of the axial support 31 extending out of the limiting hole 30 faces the end face of the wind turbine coupling and is spaced apart from the end face of the wind turbine coupling. A third elastic element 32 is provided inside the limiting hole 30. The portion of the axial support 31 located inside the limiting hole 30 is pressed against the third elastic element 32. A third limiting post 33 is also provided at the bottom of the limiting hole 30. A third elastic pressure sensor 34 protruding from the upper end face of the third limiting post 33 is provided in the middle of the third limiting post 33.

[0054] In application, when the main support 5 rises and / or swings left and right, it drives the limiting member 29 to rise and / or swing left and right through the swing rod 19 and horizontal sliding rod 27 of the linkage assembly 8. Since the axial support 31 is spaced (3~8mm) from the end face of the wind turbine coupling, it will not contact the wind turbine coupling. However, when the wind turbine coupling undergoes axial displacement, it will contact the axial support 31 of one of the limiting members 29 after the axial displacement. The flexible limiting of the axial support 31 restricts the direction of its axial displacement, preventing it from continuing to move axially. The displacement is provided by the third elastic element 32, which provides flexible support to avoid affecting the normal operation of the coupling. In this process, the axial support 31 is forced to keep the horizontal sliding rod 27 horizontal or the end connected to the column 21 is slightly tilted up, thereby supporting the main support 5 through the linkage component 8 to increase its support force, or forcing the main support 5 to move slightly upward to increase the support force of the wind power coupling. By providing a reverse force, the wind power coupling is forced to move in the opposite direction, which effectively alleviates the further axial displacement trend of the wind power coupling.

[0055] Furthermore, when the wind turbine coupling moves excessively and forces the axial support 31 to retract into the limiting hole 30, it can compress the third elastic pressure sensor 34. When the third elastic pressure sensor 34 is subjected to pressure, it can send an alarm to the external control system or alarm system. Meanwhile, the third limiting post 33 provides rigid support to the axial support 31 and restricts its retraction, ensuring that the wind turbine coupling will not undergo axial displacement again and buying time for equipment maintenance.

[0056] As one of the specific implementation schemes, the first elastic element 12, the second elastic element 23, and the third elastic element 32 are all compression springs.

[0057] As one specific implementation scheme, the swing rod 19 is radially provided with a through threaded hole, and a locking screw is fitted inside the threaded hole. When the horizontal sliding rod 27 is sleeved, the locking screw is screwed in and abuts against the surface of the horizontal sliding rod 27 to lock it. Furthermore, the sleeve depth of the horizontal sliding rod 27 can be adjusted according to the distance requirements between the axial support 31 and the end of the wind turbine coupling, and locking can be completed after adjustment. This allows the distance between the axial support 31 and the end of the wind turbine coupling to be adjusted according to different distance requirements, thereby meeting the needs of different models and operating conditions of wind turbine couplings.

[0058] As one specific implementation method, the main support 5 and the auxiliary support 18 are both arc-shaped structures, and the main support 5, the auxiliary support 18 and the axial support 31 are all provided with a number of balls protruding from the corresponding end faces of the wind power coupling.

[0059] It should be noted that the axial support 31, whether in its initial position or in the linkage state, should always correspond to the end of the wind turbine coupling and be located inside the end area. This ensures that, in any case, it can limit and support the axial direction of the wind turbine coupling.

[0060] like Figure 6 As shown, in one feasible implementation, the linkage assembly 8 includes a first linkage rod 35, a second linkage rod 36, and a linkage plate 37; the two sides of the main support 5 are rotatably connected to the first linkage rod 35 and the second linkage rod 36 respectively, and the lower ends of the two rotating supports 7 are rotatably connected to the first linkage rod 35 or the second linkage rod 36 on the same side respectively; two linkage plates 37 are provided and fixed to the same side end of the first linkage rod 35 and the second linkage rod 36 respectively, and a hinge shaft 38 is provided in the middle of the outer side of each of the two linkage plates 37, and the hinge shaft 38 is hinged to the swing rods 19 on both sides respectively.

[0061] During implementation, when the main support 5 rises and / or swings left and right, it synchronously drives the first linkage rod 35, the second linkage rod 36 and the linkage plate 37 to rise and fall, or drives the entire linkage assembly 8 to swing left and right. Then the linkage plate 37 rotates in the circumferential direction, driving the swing rod 19 to swing up and down, so as to achieve the synchronous linkage effect of the main support 5, the secondary support 18 and the axial support 31.

[0062] For specific application solutions, please refer to [link / reference]. Figure 1 The lifting base 1 includes a horizontal mounting plate 39, a lifting component 40 fixed in the middle of the horizontal mounting plate 39, and a multi-functional base 41 fixed to the top of the lifting end of the lifting component 40. The floating support component 2 and the rotating support component 3 are both disposed on the multi-functional base 41.

[0063] During implementation, the horizontal mounting plate 39 is fixed to the corresponding horizontal infrastructure (such as the positioning base of the output or input system in a wind turbine generator set). The lifting component 40 can lift and lower the multi-functional base 41 to adjust the support height of the floating support component 2 and the rotating support component 3, so that the height can be adjusted and effectively supported according to the needs of the coupling.

[0064] In a specific implementation, both the lifting assembly 40 and the lifting bracket 6 are electric telescopic cylinders; the multi-functional base 41 has an electrical cavity, and a control system is installed inside the electrical cavity. Both the lifting assembly 40 and the lifting bracket 6 are electrically connected to the control system. The control system can control the automatic lifting of the lifting assembly 40 and the lifting bracket 6, thereby facilitating the height adjustment and use of the overall bracket.

[0065] As one specific implementation scheme, the aforementioned first elastic pressure sensor 15, second elastic pressure sensor 25, and third elastic pressure sensor 34 are all electrically connected to the control system. Therefore, when the first elastic pressure sensor 15, second elastic pressure sensor 25, and third elastic pressure sensor 34 are subjected to force and emit signals, the control system can receive the signals and issue alarm signals based on external alarm devices or alarm systems connected to the system, thus providing effective control and warning.

[0066] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
