In the detailed description below, many specific details are proposed in order to provide a comprehensive understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without the need for some of these specific details. The following description of the embodiment is only to provide a better understanding of the utility model by illustrating an example of the utility model. In the drawings and the following description, at least part of the known structures and technologies are not shown in order to avoid unnecessary ambiguity to the utility model; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0030] The directional words appearing in the following description are all directions shown in the figure, and do not limit the specific structure of the disassembly tooling of the utility model. In the description of the utility model, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0031] In order to better understand the present invention, Figures 1 to 7 The disassembly tool for a wind turbine generator set according to an embodiment of the utility model is described in detail.

[0032] See also Figure 1The embodiment of the utility model proposes a disassembly tool 100 for a wind turbine generator set, including a plug-in connector 10, a mating assembly and a grabbing member 40, wherein the plug-in connector 10 extends along a first direction; the mating assembly includes an adjusting ring 20 and a bearing member 30, wherein the adjusting ring 20 has a plug-in hole, the plug-in connector 10 is plugged into the plug-in hole and the adjusting ring 20 can move along the first direction on the plug-in connector 10, the bearing member 30 includes a connecting portion 31 and a supporting portion 32, a first connecting ring 33 is provided on the connecting portion 31 and can be detachably sleeved on the plug-in connector 10 through the first connecting ring 33, the supporting portion 32 is provided on the connecting portion 31 and protrudes away from the side where the adjusting ring 20 is located along the first direction; the grabbing member 40 includes a second connecting ring 41 and a plurality of grabbing portions 42, the second connecting ring 41 can be detachably sleeved on the plug-in connector 10, a plurality of grabbing portions 42 are arranged at intervals on the second connecting ring 41, and the grabbing member 40 can move along the first direction relative to the plug-in connector 10.

[0033] Optionally, the connector 10 may be a rod-shaped structure, and the adjustment ring 20 in the mating component may adopt an adjustment nut structure, which is sleeved on the connector 10 using its own insertion hole to form a detachable connection with the connector 10, thereby facilitating the disassembly and assembly of the adjustment ring 20.

[0034] Optionally, the plug-in hole of the adjusting ring 20 is provided with an internal thread, and the outer surface of the connector 10 is provided with an external thread, so that the adjusting ring 20 can form a threaded connection with the connector 10, and the adjusting ring 20 can move on the connector 10 on the basis that both are detachable.

[0035] During operation, it is necessary to use the adjustment ring 20 to cooperate with the carrier 30. Specifically, the support part 32 of the carrier 30 supports the entire structure, and a detachable connection is formed with the connector 10 through the connecting part 31. When the carrier 30 needs to be installed, the first connecting ring 33 on the connecting part 31 is sleeved on the connector 10, and the supporting part 32 connected to the connecting part 31 abuts against the surface of the pitch drive assembly, thereby forming a stable support.

[0036] After completing the installation of the above structure, it is first necessary to lift the drive shaft in the variable pitch drive assembly. Optionally, the thread on the connector 10 can be used to form a threaded connection with the threaded hole of the drive shaft, that is, the connector 10 is inserted into the drive shaft. At this time, the support portion 32 abuts against the platform around the drive shaft to form a support.

[0037] Then move the adjusting ring 20 and adjust its position on the connector 10 so that the adjusting ring 20 gradually moves toward the supporting member 30 at the bottom. When the adjusting ring 20 moves to the first connecting ring 33 of the connecting portion 31, it is blocked. After the adjusting ring 20 continues to be screwed downward, under the reaction force of the supporting portion 32, the adjusting ring 20 and the first connecting ring 33 remain relatively still, and the connector 10 forms a reverse movement, so that the connector 10 can drive the drive shaft connected thereto to move upward together, thereby gradually completing the lifting of the drive shaft and gradually separating the drive shaft from the assembly.

[0038] After taking out the above-mentioned drive shaft, remove the adjustment ring 20 and the carrier 30 on the connector 10, and sleeve the grabbing member 40 on the connector 10 through the second connecting ring 41. Optionally, the two can also be connected by a thread so that the grabbing member 40 can move on the connector 10 as a whole.

[0039] Among them, a plurality of grabbing parts 42 are arranged on the second connecting ring 41 of the grabbing member 40. The function of the grabbing parts 42 is to directly abut against the variable pitch bearing in the drive shaft to facilitate the grabbing of the bearing. The utility model does not specifically limit the number and structure of the grabbing parts 42, and can be adjusted according to actual grabbing needs. The figure takes the setting of three grabbing parts 42 as an example, and the grabbing parts 42 are set as a hook-shaped structure for explanation.

[0040] After completing the above installation, optionally, under the action of the threaded connection, the grabbing member 40 is driven to move relative to the connector 10 by screwing the connector 10. When the grabbing member 40 gradually moves upward on the connector 10, the variable pitch bearing connected thereto can be driven to be gradually pulled out from the drive shaft, thereby completing the disassembly process of the variable pitch bearing.

[0041] In this embodiment, the application of the disassembly tool 100 in a wind turbine is used as an example for explanation. When the pitch bearing in the wind turbine is damaged and needs to be replaced, the drive shaft needs to be pulled out of the pitch drive assembly using the disassembly tool 100. Specifically, the pulling process is completed by using the connector 10 and the adjustment ring 20 and the carrier 30 sleeved on the connector 10 to cooperate with each other.

[0042] After the above-mentioned drive shaft is removed from the pitch drive assembly, the adjustment ring 20 and the carrier 30 on the connector 10 are removed, and the grabbing piece 40 is sleeved on the connector 10. The grabbing piece 40 is used to grab the pitch bearing in the drive shaft until the pitch bearing is extracted from the drive shaft, thereby completing the disassembly operation of the pitch bearing.

[0043] The disassembly tool 100 in this embodiment is used for disassembling the variable pitch bearings in the wind turbine generator set. When facing different components of the unit in different steps, the parts of the disassembly tool 100 can be flexibly disassembled and assembled to adapt to the two individuals that need to be coordinated, namely the variable pitch drive assembly and the drive shaft. The disassembly tool 100 can be used as a whole to complete the two-step independent disassembly process, making the disassembly tool 100 provided in this embodiment better suitable for the structure in the wind turbine generator set.

[0044] The embodiment of the utility model provides a disassembly tool 100 for a wind turbine generator set, which can detachably connect a mating component on a plug-in component 10, utilize an adjusting ring 20 and a bearing member 30 in the mating component, enable the bearing member 30 to abut against the surface of a pitch drive assembly, and utilize the movement of the adjusting ring 20 sleeved on the plug-in component 10 on the plug-in component 10 to drive the plug-in component 10 to move upward, thereby driving the drive shaft connected to the plug-in component 10 to move upward, thereby completing the lifting of the pitch bearing in the pitch drive assembly, so that the disassembly tool 100 can be suitable for removing the pitch bearing in the environment of the pitch drive assembly. The process is simple and convenient to operate, which can speed up the operation process and improve the operation efficiency. At the same time, after the drive shaft is taken out, the grabbing piece 40 is reinstalled on the connector 10, and the grabbing piece 40 can move on the connector 10 to drive the variable pitch bearing abutting against the grabbing piece 40, and the variable pitch bearing is pulled out from the drive shaft to complete the disassembly process of the variable pitch bearing. Through the two-step operation process, the disassembly tool 100 is better suitable for the application environment of the variable pitch drive assembly, and it is convenient for the staff to complete the operation, and the disassembly of the variable pitch bearing is completed quickly and efficiently, with higher disassembly efficiency.

[0045] As an alternative embodiment, see Figure 1 The connecting portion 31 includes a rod-shaped structure, and the connecting portion 31 extends along the second direction, and the first direction and the second direction are perpendicular to each other.

[0046] In this embodiment, the connecting portion 31 is configured as a rod-shaped structure. The connecting portion 31 in the supporting member 30 plays a connecting role. Specifically, it is detachably connected to the plug-in connector 10 through its own first connecting ring 33, and the supporting portion 32 connected thereto is used to support the entire structure.

[0047] When the first direction and the second direction are perpendicular, the connector 10 and the connecting portion 31 form a perpendicular relationship, and the supporting portion 32 extending along the first direction and the connecting portion 31 also form a perpendicular relationship, so that the supporting portion 32 can form a vertical support with the platform of the drive assembly.

[0048] The embodiment of the utility model provides a disassembly tool 100, which forms a vertical connection between the connector 10 and the carrier 30 by keeping the first direction and the second direction perpendicular, so that the overall structure has better stability, ensuring the stability of the force on the overall structure during the movement and coordination of the adjustment ring 20, and providing reliable protection for the lifting process of the drive shaft.

[0049] As an optional embodiment, the carrier 30 includes a plurality of supporting portions 32 , and the plurality of supporting portions 32 are disposed on the connecting portion 31 at intervals from each other.

[0050] In order to improve the stability during the process of lifting the drive shaft, in the present embodiment, a plurality of support portions 32 are arranged on the connecting portion 31, so that during the operation, the plurality of support portions 32 can simultaneously support the platform of the drive assembly, thereby improving the overall support strength of the carrier 30 and having higher structural stability. The present invention does not impose any special limitation on the specific number of the support portions 32 arranged.

[0051] The embodiment of the utility model provides a disassembly tool 100, which arranges multiple support parts 32 on the connecting part 31 and uses the multiple support parts 32 to provide reverse supporting force, so that the multiple support parts 32 can disperse the supporting force, avoiding damage to the support parts 32 caused by stress concentration, forming better stress protection for the multiple support parts 32, and improving the reliability of the overall structure.

[0052] As an alternative embodiment, see Figure 1 The first connecting ring 33 is located in the middle of the connecting portion 31 , and at least the supporting portions 32 are distributed on both sides of the first connecting ring 33 on the connecting portion 31 .

[0053] Optionally, the first connecting ring 33 can be arranged at the midpoint of the connecting portion 31. When the connecting portion 31 is sleeved on the connector 10 through the first connecting ring 33, a cross structure is formed as a whole. At the same time, multiple supporting portions 32 are respectively arranged on both sides of the first connecting ring 33. The multiple supporting portions 32 can support both sides of the connecting portion 31 at the same time.

[0054] The utility model does not impose any special limitation on the number of the supporting parts 32 on both sides of the first connecting ring 33 , and can be flexibly adjusted according to actual support requirements and the balance requirements of the overall structure of the bearing member 30 .

[0055] The embodiment of the utility model provides a disassembly tool 100, which can ensure the balance and stability of the entire connecting part 31 after being connected to the connector 10 by arranging the first connecting ring 33 at the midpoint of the connecting part 31. At the same time, the supporting parts 32 are arranged on both sides of the first connecting ring 33, which also ensures the force balance of the connecting part 31 during the supporting process, avoiding the displacement of the connecting part 31 caused by uneven force, and providing reliable guarantee for effectively lifting the driving shaft.

[0056] As an alternative embodiment, see Figure 1 The plurality of support portions 32 include a first support portion and a second support portion. The first support portion and the second support portion are respectively disposed on both sides of the first connecting ring 33 and are symmetrically distributed with the first connecting ring 33 as an axis.

[0057] In this embodiment, two support parts 32 are provided, namely a first support part and a second support part. The two support parts 32 are respectively provided on both sides of the first connecting ring 33. Meanwhile, the first support part and the second support part are symmetrically distributed with the first connecting ring 33 as the center.

[0058] It can be understood that the distances from the first support portion and the second support portion to the first connecting ring 33 are equal, so that when the support portion 32 is used to form support, the two support portions 32 can not only bear part of the supporting force respectively, but also ensure that the supporting forces formed at the two places are equal to average the supporting forces.

[0059] Optionally, when the carrier 30 has a plurality of support portions 32 , the plurality of support portions 32 may be symmetrically arranged at the same time according to the actual number of support portions 32 , so as to evenly distribute the support force, so that the support force on the support portion 32 is equal everywhere.

[0060] The embodiment of the utility model provides a disassembly tool 100, which symmetrically arranges the first support part and the second support part on both sides of the first connecting ring 33. While utilizing the support part 32 to form a supporting fit, the force on the support part 32 can be averaged to be equal everywhere, thereby avoiding the problem of stress concentration and further ensuring the balance and stability of the overall structure, preventing structural imbalance during the pulling process.

[0061] As an optional embodiment, the support portion 32 is detachably connected to the connecting portion 31 , and the support portion 32 can move on the connecting portion 31 , so that the position of the support portion 32 on the connecting portion 31 is adjustable.

[0062] Optionally, the support portion 32 and the connecting portion 31 can be connected by a thread, which not only enables the two to be detachable, but also allows the support portion 32 to be moved relative to the connecting portion 31 by using the thread, thereby adjusting the position of the support portion 32 relative to the connecting portion 31 and performing flexible adjustment.

[0063] Specifically, the number of support parts 32 can be adjusted according to the actual supporting force requirements. The adjustment can be made by disassembling the support parts 32, or the position of the support parts 32 relative to the connecting part 31 can be adjusted according to the actual balance requirements of the connecting part 31 to ensure that the support parts 32 can form a stable support for the connecting part 31 so that the connecting part 31 remains balanced.

[0064] The embodiment of the utility model provides a disassembly tool 100, which enables the support part 32 to be moved and adjusted on the connecting part 31, thereby facilitating the flexible disassembly and assembly of the support part 32, facilitating the adjustment of the overall supporting capacity of the structure and the balance adjustment of the connecting part 31, so that the overall structure has better adjustment flexibility to meet different actual disassembly and assembly needs.

[0065] As an alternative embodiment, see Figure 1 Combined with Figures 2 to 4 The support portion 32 includes a connecting sleeve 34 and a supporting column 35. The supporting column 35 is connected to the connecting sleeve 34 and extends along the first direction toward a side away from the adjusting ring 20. The connecting sleeve 34 is sleeved on the connecting portion 31 and is threadedly connected to the connecting portion 31.

[0066] Optionally, an internal thread is provided in the connecting sleeve 34 of the support portion 32, and an external thread is provided on the outer surface of the connecting portion 31, so that the connecting sleeve 34 can be sleeved on the connecting portion 31 to form a threaded connection, and the support portion 32 as a whole can be moved and adjusted on the connecting portion 31 through the thread.

[0067] A support column 35 is provided on the connecting sleeve 34, and the supporting portion 32 specifically supports the connecting portion 31 through the support column 35. The support column 35 directly abuts against the platform of the driving assembly. The support column 35 can select a corresponding size according to the actual support strength requirements. Optionally, the support column 35 and the connecting sleeve 34 can be an integrally formed structural part.

[0068] The embodiment of the utility model provides a disassembly tool 100, which provides a specific structural form of a support part 32. By utilizing the connecting sleeve 34 therein, a detachable and adjustable threaded connection can be formed with the connecting part 31, and the support column 35 is utilized to directly support the connecting part 31, while satisfying the adjustment requirements and support requirements of the support part 32. At the same time, the embodiment has a simple structure and is easy to form.

[0069] As an alternative embodiment, see Figure 1 Combined with Figure 5The disassembly tool 100 also includes an adapter 50, which is detachably connected to one end of the connector 10 close to the carrier 30. The adapter 50 includes a docking sleeve 51 and a plug rod 52. The docking sleeve 51 is sleeved on one end of the connector 10 and is detachably connected to the connector 10. The plug rod 52 is connected to the docking sleeve 51 and extends toward a side away from the connector 10. The radial dimension of the plug rod 52 is smaller than the radial dimension of the connector 10.

[0070] Considering that the drive shaft has threaded holes of different sizes during the process of plugging the connector 10 with the drive shaft, in this embodiment, an adapter 50 is connected to the end of the connector 10 to plug it with the drive shaft to achieve effective connection with the drive shaft.

[0071] The adapter 50 is specifically connected to the bottom end of the plug-in connector 10 via its own docking sleeve 51. Optionally, the docking sleeve 51 is provided with an internal thread that can form a threaded connection with the external thread on the plug-in connector 10. The adapter 50 can be screwed into the bottom end of the plug-in connector 10.

[0072] A plug-in rod 52 structure extends from the docking sleeve 51, and specifically the plug-in rod 52 is used to connect with the drive shaft. The radial dimension of the plug-in rod 52 is smaller than the radial dimension of the connector 10, thereby realizing a variable diameter connection of the connector 10, making it easier to use the plug-in rod 52 to complete the connection with the smaller threaded hole of the drive shaft.

[0073] The embodiment of the utility model provides a disassembly tool 100, which can detachably connect the adapter 50 at one end of the connector 10, so that the plug-in rod 52 of the adapter 50 is plugged into the drive shaft, and its radial dimension is set to be smaller than the radial dimension of the connector 10, thereby realizing the diameter conversion of the connector 10, which is beneficial to realize the connection between the tool and the smaller-sized threaded hole, has better adaptability, and meets more actual working conditions.

[0074] As an alternative embodiment, see Figure 1 Combined with Figure 6 The second connecting ring 41 includes a ring body 43 and a plurality of protrusions 44 arranged on the ring body 43. The protrusions 44 protrude from the outer surface of the ring body 43 along the radial direction of the ring body 43, and the grasping portion 42 is detachably connected to the protrusions 44.

[0075] As for the specific structure of the second connecting ring 41 in the grabbing member 40, it specifically includes a ring body 43 and a plurality of protrusions 44 arranged on the ring body 43. Optionally, the inner wall of the ring body 43 is provided with an internal thread, so that it can form a threaded connection with the external thread on the connector 10, so that the grabbing member 40 as a whole can be moved and adjusted on the connector 10.

[0076] Optionally, the protrusion 44 can be a lug structure, and the second connecting ring 41 can utilize the protrusion 44 to be detachably connected to the grabbing portion 42, specifically by bolt connection, and multiple grabbing portions 42 can be flexibly disassembled and assembled according to different actual quantity requirements.

[0077] The embodiment of the utility model provides a disassembly tool 100, which provides a specific structural form of the second connecting ring 41 by arranging a protrusion 44 on the second connecting ring 41 and forming a detachable connection with the grasping portion 42, thereby facilitating flexible disassembly and assembly of the grasping portion 42, improving the adaptability to grasping the variable pitch bearing, and meeting different grasping requirements.

[0078] As an alternative embodiment, see Figure 1 Combined with Figure 7 The grabbing portion 42 includes a first bending portion 1 and a second bending portion 2 connected to each other, one end of the first bending portion 1 is connected to the protruding portion 44 and the other end is connected to the second bending portion 2, the first bending portion 1 extends toward a side gradually away from the connector 10 and the second bending portion 2 extends toward the connector 10, and an acute angle is formed between the first bending portion 1 and the second bending portion 2.

[0079] As for the specific structure of the grabbing portion 42, optionally, it can be set to a hook-shaped structure, which is specifically formed by bending the first bending portion 1 and the second bending portion 2, and a bending structure with an acute angle can be formed between the two. Specifically, the variable pitch bearing is hooked through the second bending portion 2, and the grabbing member 40 as a whole constitutes a three-claw puller structure.

[0080] When multiple grabbing parts 42 hook the variable pitch bearing at the same time, the drive connector 10 is rotated, thereby driving the grabbing part 40 to climb on the connector 10, and then gradually pulling the hooked variable pitch bearing upward, thereby separating the variable pitch bearing from the drive shaft and completing the disassembly process of the variable pitch bearing.

[0081] The utility model does not impose any special limitation on the angle value between the first bending portion 1 and the second bending portion 2 , as long as a hook-shaped structure can be formed to stably abut the variable pitch bearing. Optionally, the grabbing portion 42 structure can be integrally formed.
