Description

Technical Field

[0001] This utility model relates to the field of wind power generation equipment, and more specifically to a wind turbine centering adjustment device. Background Technology

[0002] In the field of wind power equipment manufacturing, wind turbines need to be aligned with the high-speed shaft of the gearbox to ensure they are coaxial. This alignment process is an essential part of wind turbine assembly. The generator weighs approximately 15-20 tons, and the required alignment accuracy for the XYZ axes is approximately ±0.1 mm.

[0003] Combination Figure 14 The diagram illustrates the existing generator alignment mechanism. The generator is pre-installed on the elastic support 01. The operator installs four sets of X-axis adjustment devices 02, two sets of Y-axis adjustment devices 03, and four sets of Z-axis adjustment devices 04 on the nacelle base 05. Operator 1 confirms the alignment instrument data at the generator input shaft position (station ①). Operators 2 (station ②) and 4 (station ④) are responsible for the X-axis adjustment devices 02 and Z-axis adjustment devices 04 at the two bottom corners of the generator's front end. Operators 3 (station ③) and 5 (station ⑤) are responsible for the X-axis adjustment devices 02, Y-axis adjustment devices 03, and Z-axis adjustment devices 04 at the two bottom corners of the generator's rear end.

[0004] Operator 1 confirms the alignment instrument data and informs Operators 2, 3, 4, and 5 of the XYZ axis adjustment amounts. Operators 2, 3, 4, and 5 use the Z-axis adjustment device to lift the generator, ensuring it is not in contact with the elastic support 01, with the generator supported by the Z-axis adjustment device 04. Operators 2, 3, 4, and 5 lower the elastic support 01 as needed to prevent it from restricting the Z-axis adjustment stroke.

[0005] Operators 2, 3, 4, and 5 use the Z-axis adjustment device to adjust the Z-axis deviation up and down. Once the Z-axis deviation meets the requirements (operator 1 confirms the data in real-time using the alignment instrument and informs operators 2, 3, 4, and 5), operators 2, 3, 4, and 5 adjust the elastic support 01 to contact the generator, relying on the elastic support 01 to support the generator. Then, remove the Z-axis adjustment device 04.

[0006] When the elastic support 01 contacts the generator, the force of the adjustment device is transferred to the elastic support to cause deformation when the X-axis / Y-axis is adjusted. As a result, the elastic support will recover its deformation after the adjustment device is removed, which affects the adjustment accuracy.

[0007] Assuming the generator shifts to the left along the X-axis, operators 2 and 3 use the X-axis adjustment device (left) to push the generator to the right:

[0008] Scenario 1 (Reading error due to elastic support deformation recovery): When the X-axis deviation value meets the requirements (operator 1 confirms the data in real time through the alignment instrument and informs operators 2-3), the operator removes the force of the X-axis adjustment device (left), the elastic support deformation recovers, and the generator is still deviated to the left in the X-axis direction. Repeat until the X-axis deviation still meets the requirements after removing the force to the right of the X-axis adjustment device (left).

[0009] Scenario 2 (Over-adjustment): When the X-axis adjustment is over-adjusted, the generator deviates to the right in the X-axis direction. Operators 2-3 remove the force from the left X-axis adjustment device. Operators 4-5 use the right X-axis adjustment device to push the generator to the left until the X-axis deviation still meets the requirements.

[0010] Assuming the generator shifts backward along the Y-axis, operators 3 and 5 use the Y-axis adjustment device 03 to push the generator forward:

[0011] Case 1 (reading error due to elastic support deformation recovery): When the Y-axis deviation meets the requirements (operator 1 confirms the data in real time through the alignment instrument and informs operators 3 and 5). The operator removes the force of the Y-axis adjustment device, the elastic support deformation recovers, and the generator is still biased backward in the Y-axis direction. Repeat (17) until the forward force of the Y-axis adjustment device is removed and the Y-axis deviation still meets the requirements.

[0012] Scenario 2 (Over-adjustment): When the Y-axis adjustment is over-adjusted, the generator deviates forward in the Y-axis direction. Operators 3 and 5 remove the hydraulic cylinder portion of the Y-axis adjustment device and install it in reverse. Operators 3 and 5 use the Y-axis adjustment device to push the generator backward until the Y-axis deviation still meets the requirements.

[0013] The Y-axis adjustment device can switch between forward and backward adjustment functions in the Y-axis direction by installing a hydraulic cylinder in the opposite direction.

[0014] After adjustment, tighten the connecting bolts of the elastic support and generator. Remove all adjustment devices.

[0015] Traditional adjustment structures require the combined efforts of five operators, involving a large number of people; moreover, the adjustment of the three axes XYZ needs to be carried out separately, making the structure relatively complex, with a low degree of integration, and difficult to install, store, and manage.

Detailed Implementation

[0056] To enable those skilled in the art to better understand the technical solution of this utility model, the wind turbine centering adjustment device of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] This utility model provides a wind turbine centering adjustment device, applied during the assembly process of a wind turbine, which can realize the centering adjustment of the wind turbine's shaft. Combined with... Figure 1 , Figure 2 As shown, the wind turbine centering adjustment device includes two first adjustment modules 10 and two second adjustment modules 20, respectively, for fixed installation on the nacelle base 30; the nacelle base 30 is fixed to the wind turbine frame and supports the generator 40. (Combined with...) Figure 3 As shown, several elastic support seats 50 are provided on the nacelle base 30, and the generator 40 is fixedly supported by the elastic support seats 50. Before the generator 40 is finally fixedly assembled, the positions of the generator 40 in the XYZ axes need to be adjusted by the cooperation of the first adjustment module 10 and the second adjustment module 20. After the position adjustment is completed, the generator 40 is fixedly assembled on the elastic support seats 50, and the first adjustment module 10 and the second adjustment module 20 are removed.

[0058] Combination Figure 1 , Figure 2 As shown, the generator 40 is installed at an angle. Along the direction of the generator 40's rotation axis, one end is lower and the other end is higher. The axle extends from the higher end. The purpose of adjusting the generator 40 is to align the generator's output shaft with the gearbox's high-speed shaft so that the two can rotate coaxially.

[0059] The first adjustment module 10 is used to support the higher end of the generator 40 along the axial direction, and the second adjustment module 20 is used to support the lower end of the generator 40 along the axial direction. It should be noted that the first adjustment module 10 is located near the higher end of the generator 40, and the second adjustment module 20 is located near the lower end of the generator 40. It is not required that the first adjustment module 10 and the second adjustment module 20 be located on the end face of the generator 40. Usually, the first adjustment module 10 and the second adjustment module 20 are connected to the lower surface of the generator 40.

[0060] Combination Figure 1 , Figure 2 , Figure 3 As shown, the X-axis represents the width of generator 40, the Y-axis represents the length of generator 40, and the Z-axis represents the height of generator 40. The Y-axis is parallel to the axis of rotation of generator 40, and the X-axis and Z-axis are perpendicular to the Y-axis. Since the Y-axis is not horizontal, the Z-axis is not vertical and has a certain angle with the vertical plane.

[0061] The wind turbine centering adjustment device of this utility model includes two first adjustment modules 10 and two second adjustment modules 20. More first adjustment modules 10 and second adjustment modules 20 can be set, but at least two first adjustment modules 10 and two second adjustment modules 20 should be set. Each first adjustment module 10 forms a support point for the generator 40, and each second adjustment module 20 forms a support point for the generator 40, forming at least four support points for the generator 40.

[0062] The first adjustment module 10 and the second adjustment module 20 each have a guiding structure and a power structure, with the guiding structure providing guidance and limiting, and the power structure providing driving force. The first adjustment module 10 and the second adjustment module 20 each include a base assembly 101, an X-axis guide assembly 102, and a Y-axis guide assembly 103, where the X-axis guide assembly 102 and the Y-axis guide assembly 103 are guiding structures. The base assembly 101 is used to mount on the nacelle 30. When adjusting the position of the generator 40, the base assemblies 101 of the first adjustment module 10 and the second adjustment module 20 are fixed to the nacelle 30. After adjustment, the base assemblies 101 are removed from the nacelle 30.

[0063] The Y-axis guide assembly 103 is mounted on the base 101. The Y-axis guide assembly 103 is used to guide the X-axis guide assembly 102 to move along the Y-axis; the X-axis guide assembly 102 is used to guide the generator 40 to move along the X-axis; that is, the generator 40 can be guided by the Y-axis guide assembly 103 to translate along the Y-axis direction, and the generator 40 can be guided by the X-axis guide assembly 102 to translate along the X-axis direction. No guide structure is required in the Z-axis direction.

[0064] Combination Figure 4 , Figure 5As shown, the power structure of the first adjustment module 10 and the power structure of the second adjustment module 20 may not be exactly the same. The first adjustment module 10 includes an X-axis drive assembly 201 and a Z-axis drive assembly 203; the second adjustment module 20 includes an X-axis drive assembly 201, a Y-axis drive assembly 202, and a Z-axis drive assembly 203. The X-axis drive assembly 201, the Y-axis drive assembly 202, and the Z-axis drive assembly 203 can all be hydraulic cylinders or other power structures.

[0065] The Y-axis drive assembly 202 drives the generator 40 to translate axially; the X-axis drive assembly 201 drives the generator 40 to translate along the width direction; and the Z-axis drive assembly 203 drives the generator 40 to move vertically. The X-axis guide assembly 102 is mounted on the Y-axis guide assembly 103 and, under the force of the Y-axis drive assembly 202, can move along the Y-axis. The Z-axis drive assembly 203 is mounted on the X-axis guide assembly 102. The X-axis drive assembly 201 drives the Z-axis drive assembly 203 to move along the X-axis, and the Z-axis drive assembly 203 drives the generator 40 to move vertically along the Z-axis.

[0066] During adjustment, the first adjustment module 10 and the second adjustment module 20 are each equipped with an X-axis drive assembly 201, which synchronously drives the generator 40 to move along the X-axis and provides X-axis guidance through the X-axis guide assembly 102. The first adjustment module 10 and the second adjustment module 20 are each equipped with a Y-axis guide assembly 103 to provide Y-axis guidance. Only the Y-axis drive assembly 202 located in the lower part of the second adjustment module 20 provides an upward thrust along the Y-axis. Since the component of the generator 40's gravity along the Y-axis is downward, the first adjustment module 10 does not need to be equipped with a downward thrust structure along the Y-axis; the generator 40 can achieve downward displacement by its own gravity. The generator 40 is driven to rise and fall by the Z-axis drive assembly 203 located in the first adjustment module 10 and the second adjustment module 20, and the height of the generator is mainly adjusted by the Z-axis drive assembly 203.

[0067] The first adjustment module 10 and the second adjustment module 20 each integrate a guiding structure for the XYZ axes, and the two are combined with a drive structure for the XYZ axes. The adjustment of the XYZ axes can be performed in any order, without any specific order. This integration of three-axis adjustment simplifies the adjustment process, making it easier to install, store, and manage the generator, and reducing the manpower required for adjustment.

[0068] Based on the above scheme, combined with Figure 6As shown, the base 101 of this utility model includes a fixed base 1011 and a rotating base 1012. The bottom plate of the fixed base 1011 contacts the nacelle base 30, and the fixed base 1011 is fixedly installed on the nacelle base 30 by bolts. The rotating base 1012 is hinged to the fixed base 1011 along the X-axis direction. The hinge axis between the rotating base 1012 and the fixed base 1011 is along the X-axis direction. When the pitch angle of the generator 40 is adjusted, the rotating base 1012 rotates accordingly. The Y-axis guide assembly 103 is installed on the rotating base 1012. The Y-axis guide assembly 103 and the X-axis guide assembly 102, Z-axis drive assembly 203, generator 40, and other structures installed on it rotate synchronously.

[0069] In some embodiments, the second adjustment module 20 includes a fixed connector 104, which is combined with Figure 13 As shown, the fixed connector 104 includes a fixed base plate 1041 and a fixed folding plate 1042 that are fixed in a bent shape. The fixed base plate 1041 and the fixed folding plate 1042 form an L-shaped bent structure. The fixed base plate 1041 is fixed to the bottom surface of the generator 40 by a first bolt 1043, and the fixed folding plate 1042 is fixed to the rear end face of the generator 40 by a second bolt 1044. The fixed connector 104 and the generator 40 are fixed to form an integral structure. When the Y-axis drive assembly 202 is driven along the Y-axis direction, it can maintain synchronous displacement with the generator 40. Whether the generator 40 moves upward or downward, it is synchronized with the extension and retraction of the Y-axis drive assembly 202.

[0070] Combination Figure 11 , Figure 12 As shown, two second adjustment modules 20 on the left and right sides are displayed respectively. A guide post 1045 is provided on the bottom surface of the fixed base plate 1041. The guide post 1045 is used to cooperate with the guide hole 2033 provided on the Z-axis housing 2031 of the Z-axis drive assembly 203 for guidance. Multiple guide posts 1045 are provided on the bottom surface of the fixed base plate 1041, each guide post 1045 corresponding to a guide hole 2033, which can guide the fixed connector 104 to translate along the Z-axis direction. This ensures that the displacement of the fixed connector 104 is synchronized with the drive of the Z-axis drive assembly 203.

[0071] Combination Figure 9 , Figure 10 As shown, two first adjustment modules 10 on the left and right sides are displayed respectively. The Z-axis drive assembly 203 includes structures such as a Z-axis housing 2031 and a Z-axis telescopic column 2034. The Z-axis housing 2031 of the first adjustment module 10 is provided with a lateral limiting block 2032 for limiting the generator 40. Figure 4 , Figure 5As shown, the lateral limit block 2032 protrudes upward, and a limit block 2032 is provided on each Z-axis housing 2031. The lateral limit block 2032 can contact the side wall of the generator 40, and the lateral limit block 2032 provided by the two first adjustment modules 10 limits the left and right width of the generator 40.

[0072] Based on any of the above technical solutions and their combinations, this utility model provides two first adjustment modules 10 and two second adjustment modules 20, with the two first adjustment modules 10 at the same height and the two second adjustment modules 20 at the same height.

[0073] Combination Figure 4 , Figure 5 As shown, in the two first adjustment modules 10, one is equipped with an X-axis drive assembly 201, and the other is equipped with an X-axis spring-loaded assembly 204. The X-axis spring-loaded assembly 204 is used to resist the thrust or pull of the X-axis drive assembly 201. In the two second adjustment modules 20, one is equipped with an X-axis drive assembly 201, and the other is equipped with an X-axis spring-loaded assembly 204. The X-axis spring-loaded assembly 204 is used to resist the thrust or pull of the X-axis drive assembly 201. That is to say, only one of the two first adjustment modules 10 needs to be equipped with an active drive structure, and the other provides passive force through elastic force; only one of the two second adjustment modules 20 needs to be equipped with an active drive structure, and the other provides passive force through elastic force.

[0074] The X-axis active drive of the first adjustment module 10 and the second adjustment module 20 can be set on the same side to facilitate operation by the same operator. Figure 4 The first adjustment module 10 and the second adjustment module 20 on the left side are equipped with an X-axis drive assembly 201, while the first adjustment module 10 and the second adjustment module 20 on the right side are equipped with an X-axis spring-loaded assembly 204 to resist the thrust of the X-axis drive assembly 201. Of course, this invention does not exclude the possibility of equipping each of the two first adjustment modules 10 and the two second adjustment modules 20 with an X-axis drive assembly 201. The X-axis spring-loaded assembly 204 simplifies operation; when pushed, it automatically retracts, and when retracted, it automatically drives the generator 40. If both sides are equipped with Z-axis active drive structures, synchronous extension and retraction are required, making the control logic more complex.

[0075] Specifically, the X-axis drive assembly 201 presses against and pushes one side of the Z-axis drive assembly 203, while the other side of the Z-axis drive assembly 203 is provided with an X-axis springback assembly 204, combined with... Figure 9 , Figure 11As shown, for the first adjustment module 10 and the second adjustment module 20 equipped with the X-axis drive assembly 201, an X-axis springback assembly 204 can also be provided. The X-axis springback assembly 204 and the X-axis drive assembly 201 jointly abut against both sides of the same Z-axis drive assembly 203, applying forces in opposite directions. When the X-axis drive assembly 201 retracts, the Z-axis drive assembly 203 is pushed back by the X-axis springback assembly 204. That is, in the two first adjustment modules 10, one is equipped with both the X-axis springback assembly 204 and the X-axis drive assembly 201, while the other is equipped with only the X-axis springback assembly 204; in the two second adjustment modules 20, one is equipped with both the X-axis springback assembly 204 and the X-axis drive assembly 201, while the other is equipped with only the X-axis springback assembly 204.

[0076] Combination Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, the X-axis springback assembly 204 is equipped with a springback adjustment device 2041, which can adjust the preset amount of spring force of the X-axis springback assembly 204.

[0077] Combination Figures 9 to 12 As shown, the X-axis guide assembly 102 includes an X-axis base 1021 and an X-axis slide 1022. The X-axis base 1021 is provided with an X-axis slide rail 1023 for sliding the X-axis slide 1022 and an X-axis stop 1024 for limiting the movement of the X-axis slide 1022. The X-axis slide rail 1023 and the X-axis base 1021 can be integrally formed. The X-axis slide rail 1023 is a slider extending along the X-axis direction, and its shape is a dovetail block. The X-axis slide 1022 is provided with a dovetail groove, and the X-axis slide 1022 is slidably assembled on the X-axis slide rail 1023. A Z-axis drive assembly 203 is mounted on the X-axis slide 1022 to allow the Z-axis drive assembly 203 to translate along the X-axis. The X-axis stop 1024 is provided at both ends of the X-axis base 1021 to limit the displacement limit range of the X-axis slide 1022. The X-axis slide 1022 can be fixed to the X-axis base 1021 with bolts. The size of the X-axis stop 1024 can be set according to different needs. When the X-axis stop 1024 is only used for blocking, a smaller size can be used. When the X-axis stop 1024 is used to install other structures such as the X-axis spring assembly 204, a larger size can be used.

[0078] The Y-axis guide assembly 103 includes a Y-axis base 1031 and a Y-axis slide 1032. The Y-axis base 1031 is provided with a Y-axis slide rail 1033 for sliding the Y-axis slide 1032 and a Y-axis stop 1034 for limiting the movement of the Y-axis slide 1032. The structure of the Y-axis guide assembly 103 is similar to that of the X-axis guide assembly 102, wherein the base, slide, and stop are interchangeable. The Y-axis base 1031 and the Y-axis slide rail 1033 can be integrally formed. The Y-axis slide rail 1033 extends along the Y-axis direction and is a dovetail block. The Y-axis slide 1032 is provided with a dovetail groove, thereby forming a sliding assembly. The Y-axis slide 1032 can only translate along the Y-axis direction. The Y-axis stop 1034 is provided at both ends of the Y-axis base 1031 to limit the displacement limit range of the Y-axis slide 1032. The Y-axis stop 1034 can be fixed to the Y-axis base 1031 by bolts. The size of the Y-axis stop 1034 can be set according to different needs. When the Y-axis stop 1034 is only used for obstruction (e.g.) Figure 7 A smaller size can be used when the Y-axis stop 1034 is used to install the Y-axis drive assembly 202 (such as...). Figure 8 Larger sizes can be used when ( ).

[0079] The X-axis base 1021 and the X-axis slide 1022 are fitted together to set the X-axis scale 1025; combined with Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, X-axis scales 1025 are respectively installed on the side walls of the X-axis base 1021 and the X-axis slide 1022. The X-axis scales 1025 have graduation marks. When the two X-axis scales 1025 move relative to each other, the relative position of the X-axis base 1021 and the X-axis slide 1022 can be displayed. Y-axis scales 1035 are also installed on the Y-axis base 1031 and the Y-axis slide 1032. Figure 7 , Figure 8 As shown, Y-axis scales 1035 are respectively provided on the side walls of Y-axis base 1031 and Y-axis slide 1032. Scale marks are provided on the Y-axis scales 1035. When the two Y-axis scales 1035 move relative to each other, the relative positions of Y-axis base 1031 and Y-axis slide 1032 can be displayed, making it convenient to show to the operator.

[0080] Combination Figure 9 , Figure 11 As shown, an X-axis travel adjusting bolt 2011 is provided on the X-axis stop 1024. The X-axis travel adjusting bolt 2011 is used to adjust the initial position of the X-axis drive assembly 201. Combined with... Figure 7As shown, a Y-axis travel adjusting bolt 2021 is provided on the Y-axis stop 1034. The Y-axis travel adjusting bolt 2021 is used to adjust the initial position of the Y-axis drive assembly 202. When the X-axis travel adjusting bolt 2011 is turned, the X-axis drive assembly 201 can be moved horizontally; when the Y-axis travel adjusting bolt 2021 is turned, the Y-axis drive assembly 202 can be moved horizontally. The positions of the X-axis drive assembly 201 and the Y-axis drive assembly 202 should be pre-adjusted before use. The travel adjusting bolt compensates for insufficient spring force travel in the drive assembly and return assembly.

[0081] When using it, you can follow the procedure below:

[0082] 1) Place the generator 40 on the elastic support 50 beforehand.

[0083] 2) The operator installs two sets of first adjustment modules 10 and two sets of second adjustment modules 20 onto the engine nacelle base 30 and connects them to the generator 40. (Combined) Figure 3 As shown, the four XYZ axis adjustment modules are pre-numbered. For ease of explanation, the first adjustment module 10 and the two sets of second adjustment modules 20 are all referred to as XYZ axis adjustment modules, and are marked as ①②③④ in counterclockwise order. The first adjustment module 10 on the left is numbered ①, the first adjustment module 10 on the right is numbered ④, the second adjustment module 20 on the left is numbered ②, and the second adjustment module 20 on the right is numbered ③.

[0084] 3) Operator 1 confirms the alignment instrument data at the input shaft position (front side) of generator 40, operator 2 is responsible for adjusting the XYZ axis adjustment modules ① and ②, and operator 3 is responsible for adjusting the XYZ axis adjustment modules ③ and ④.

[0085] 4) Operator 1 confirms the centering instrument data and informs Operator 2 and Operator 3 of the XYZ axis adjustment amount.

[0086] 5) Operators 2 and 3 use the Z-axis drive assembly 203 to lift the generator 40 upwards.

[0087] 6) Operators 2 and 3 should lower the elastic support seat 50 as needed to avoid the elastic support seat 50 restricting the Z-axis adjustment stroke.

[0088] 7) Operators 2 and 3 use the Z-axis drive assembly 203 to adjust the Z-axis deviation up and down.

[0089] 8) Once the Z-axis deviation value meets the requirements (operator 1 confirms the data in real time through the alignment instrument and informs operators 2 and 3),

[0090] 9) Assume that the generator shifts to the left along the X-axis.

[0091] 10) Operators 2 and 3 use the X-axis drive assembly 201 of the XYZ axis adjustment module ①③ to push the generator 40 to the right.

[0092] 11) Add the deviation value to the existing reading on the X-axis scale 1025 to make adjustments.

[0093] 12) Scenario 1 (Adjustment in place): When the X-axis deviation value meets the requirements (operator 1 only needs to confirm once with the alignment instrument, no real-time communication is required), begin Y-axis adjustment.

[0094] 13) Situation 2 (Over-adjustment): When the X-axis adjustment is over-adjusted, the generator 40 deviates to the right in the X-axis direction. Operators 2 and 3 depressurize the X-axis hydraulic cylinder (X-axis drive assembly 201) and push the generator to the left through the X-axis springback assembly 204 of the XYZ axis adjustment device ①④ to make the deviation value meet the requirements. Start Y-axis adjustment.

[0095] 14) Assume that the generator as a whole is offset backward in the Y-axis direction.

[0096] 15) Operator 3 used the Y-axis drive assembly 202 of the XYZ axis adjustment device ③④ to push the generator 40 forward.

[0097] 16) Add the deviation value to the existing reading on the Y-axis scale 1035 to make adjustments.

[0098] 17) Situation 1 (adjusted in place): When the Y-axis deviation value meets the requirements (operator 1 only needs to confirm once with the alignment instrument, no real-time communication is required).

[0099] 18) Situation 2 (Over-adjustment): When the Y-axis adjustment is over-adjusted, the generator deviates forward in the Y-axis direction. Operator 3 depressurizes the Y-axis hydraulic cylinder (Y-axis drive assembly 202). The generator's gravity component in the Y-axis acts backward to make the deviation value meet the requirements.

[0100] 19) Adjust the generator elastic support 50 so that the elastic support 50 and the generator 40 are in contact and locked together.

[0101] 20) Remove the forces acting on the X, Y, and Z axes of the adjustment device.

[0102] 21) Remove the XYZ axis adjustment modules ①②③④.

[0103] The wind turbine centering adjustment device of this utility model can achieve the following effects:

[0104] Improve efficiency: Reduce the original 5-person operation to 3-person operation, and only 3 operators are needed to complete the adjustment.

[0105] Visualization: Visual operation is achieved using the X-axis scale 1025 and Y-axis scale 1035. The parameters of the centering adjustment device are visualized, eliminating the need for feedback on the adjustment amount through the centering instrument and reducing communication. Operators can better control the adjustment force through visualization of the adjustment device, reducing the possibility of over-adjustment.

[0106] Simplified operation: The adjustment devices for the XYZ axes have been integrated. The number of adjustment devices has been reduced from 10 to 4. This also simplifies later management and maintenance.

[0107] Compatibility: To accommodate various generator tilt angles, the number of Y-axis and Z-axis adjustment devices has been reduced.

[0108] Reduced selection requirements: By using guide components for guidance and reducing friction, the selection requirements for hydraulic cylinders can be lowered. Hydraulic cylinders with smaller output can meet the usage needs and reduce the space occupied.
