Description

Technical Field

[0001] This disclosure pertains to the field of wind power generation technology, and particularly relates to a method for assembling segmented towers. Background Technology

[0002] As large-megawatt units gradually enter the market, large-sized towers are also becoming increasingly common. With the increase in tower height and diameter, manufacturing and transportation costs rise significantly. To reduce transportation costs, some large towers are now being constructed in multiple segments along their circumference for transport, thus reducing the transport height and simplifying the transportation process.

[0003] The process of assembling the segmented towers requires rotating the towers to the appropriate angle, which increases the difficulty of on-site assembly. Summary of the Invention

[0004] The main objective of this disclosure is to provide a method for assembling segmented towers to reduce the difficulty of on-site tower assembly.

[0005] To achieve the above objectives, this disclosure provides the following technical solution:

[0006] This disclosure provides a method for assembling a segmented tower, applicable to segmented towers. The segmented tower includes a first tower segment and a second tower segment. The assembly method employs a segmented tower assembly device, which includes a frame and a slewing support connected to the frame. The slewing support includes a tower segment connecting portion and a movable support assembly. The tower segment connecting portion is rotatably connected to the movable support assembly to drive the tower segment to rotate. The movable support assembly is movably connected to the frame and can drive the tower segment connecting portion to move, thereby driving the tower segment to move. The assembly method includes the following steps: connecting the first tower segment to the tower segment connecting portion; driving the tower segment connecting portion to rotate relative to the movable support assembly to drive the first tower segment to rotate to a first predetermined angle; and locking the first tower segment at the first predetermined angle to assemble it with the second tower segment at the first predetermined angle.

[0007] An exemplary embodiment of this disclosure further includes: after the first tower segment is rotated to the first predetermined angle and before the first tower segment is locked, driving the movable support assembly to move relative to the frame to a first predetermined position, so as to assemble it with the second tower segment at the first predetermined position.

[0008] Optionally, the assembly method further includes: after the first tower segment is locked at the first predetermined angle, disassembling the first tower segment from the tower segment connecting part and connecting the second tower segment to the tower segment connecting part; driving the tower segment connecting part to rotate relative to the movable support assembly again, so as to drive the second tower segment to rotate to the second predetermined angle, so as to connect with the first tower segment at the second predetermined angle.

[0009] Specifically, the assembly method of the segmented tower further includes: after the second tower segment is rotated to the second predetermined angle, driving the movable support assembly to move relative to the frame to the second predetermined position, and then aligning and splicing the second tower segment with the first tower segment.

[0010] Furthermore, the segmented tower assembly device also includes a locking component for locking the tower segments at a predetermined angle. The locking component can be connected to the end flange of the tower segment. The locking component includes a first locking part and a second locking part. The first locking part is rotatably connected to the frame, and the second locking part is fixed to the frame and spaced apart from the first locking part along a second horizontal direction. The step of locking the first tower segment at the first predetermined angle includes: connecting one circumferential end of the first end flange of the first tower segment to the first locking part; and connecting the other circumferential end of the first end flange of the first tower segment to the second locking part.

[0011] In another exemplary embodiment of this disclosure, the segmented tower assembly device further includes a bottom support, the bottom support including a lifting platform and a support roller, the lifting platform being disposed on the frame and capable of being raised and lowered relative to the frame in the height direction, the support roller being rotatably connected to the lifting platform, and the assembly method further includes: after the movable support assembly moves to the first predetermined position, driving the lifting platform to be raised and lowered in the height direction until the support roller abuts against the bottom wall of the first tower segment.

[0012] Optionally, the support roller has a cylindrical structure, and when the support roller abuts against the bottom wall of the first tower segment, the rotation axis of the support roller is parallel to the axis of the first tower segment.

[0013] Specifically, the segmented tower assembly device further includes a connecting frame. The segmented tower includes at least three tower segments. The step of assembling the first tower segment and the second tower segment together includes: assembling and fixing one circumferential end of the end flange of the first tower segment and one circumferential end of the end flange of the second tower segment that are close to each other, and the other circumferential ends are spaced apart and connected together by the connecting frame.

[0014] An exemplary embodiment of this disclosure states that the segmented tower assembly device includes two slewing supports, each including a first slewing support and a second slewing support. The segmented tower connection portion of the first slewing support is used to connect to the first tower segment and to drive the first tower segment to rotate and move. The segmented tower connection portion of the second slewing support is used to connect to the second tower segment and to drive the second tower segment to rotate and move.

[0015] Optionally, there are two segmented tower assembly devices. The first tower segment includes a first end flange and a second end flange disposed at both ends. The step of connecting the first tower segment to the slewing support includes: connecting the slewing supports of the two segmented tower assembly devices to the first end flange and the second end flange of the first tower segment, respectively.

[0016] Specifically, the segmented tower includes two tower segments, namely a first tower segment and a second tower segment. The central angle of the first tower segment is smaller than that of the second tower segment. The assembly method includes: connecting the first tower segment with its opening facing downwards to the tower segment connecting part; driving the tower segment connecting part to rotate relative to the movable support assembly to rotate the first tower segment by 180°; and lifting the second tower segment with its opening facing downwards and assembling it together with the first tower segment.

[0017] Optionally, the segmented tower includes two tower segments, namely a first tower segment and a second tower segment, wherein the central angle of the first tower segment is larger than that of the second tower segment, and the step of connecting the first tower segment to the tower segment connecting part includes: supporting the first tower segment with its opening facing upward on the support roller; and then lifting the second tower segment with its opening facing downward and assembling it together with the first tower segment.

[0018] The assembly method of the segmented tower provided in this disclosure has at least the following beneficial effects: by connecting the tower segments to the tower segment connecting part and driving the tower segment connecting part to rotate relative to the movable support assembly, the tower segments installed on the tower segment connecting part are rotated to a first predetermined angle, at which they can be assembled with the second tower segment.

[0049] Example embodiments will now be described more fully with reference to the accompanying drawings. However, it should not be construed that the embodiments of this disclosure are limited to those described herein. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted.

[0050] The tower provided in this disclosure includes at least two tower segments 50 arranged circumferentially, and the at least two tower segments 50 are assembled to form a ring tower, but this is not a limitation. Optionally, this disclosure uses a cylindrical tower as an example for illustration, but this is not a limitation.

[0051] To facilitate the assembly of segmented towers, this disclosure provides a segmented tower assembly device for connecting and rotating tower segments 50, thereby driving the tower segments 50 to rotate to a suitable angle and enabling the assembly of at least two tower segments 50.

[0052] As an example, the segmented tower assembly device is located near the axial end of the tower segment 50. In order to prevent the tower segment 50 from being stretched and deformed during the flipping process, the above-mentioned segmented tower assembly device is provided at both ends of the axial direction of the tower segment 50. When the tower segment 50 needs to be supported and flipped, the two segmented tower assembly devices can work together to make both ends of the tower segment 50 flip in the same direction at the same angle, thereby avoiding relative torsion at both ends of the tower segment 50.

[0053] Specifically, two segmented tower assembly devices can be configured, and the two segmented tower assembly devices are spaced apart along the axial direction of the tower, such that each segmented tower assembly device is located near the end of the tower segment 50. For ease of description, this disclosure uses one segmented tower assembly device as an example for illustration.

[0054] Reference Figures 1 to 3 The segmented tower assembly device includes a frame 10 and a slewing support 20. The slewing support 20 includes a tower segment connecting part 21 and a movable support assembly 22. The tower segment connecting part 21 is rotatably connected to the movable support assembly 22 so as to drive the tower segment 50 to rotate. The movable support assembly 22 is movably connected to the frame 10 and can drive the tower segment connecting part 21 to move, thereby driving the tower segment 50 to move.

[0055] This disclosure allows the tower segment connecting part 21 to be rotatably connected to the movable support assembly 22, and the movable support assembly 22 to be movably connected to the frame 10, so that the tower segment connecting part 21 can rotate relative to the frame 10 and can move in space relative to the frame 10. This enables the tower segment connecting part 21 to drive the tower segment 50 to move and / or rotate relative to the frame 10, which facilitates the on-site assembly of the tower segment 50 and reduces the difficulty of on-site tower assembly.

[0056] Reference Figure 1 and Figure 2 Specifically, the movable support assembly 22 is movably connected to the frame 10, and the tower segment connection part 21 is rotatably connected to the movable support assembly 22 about the pivot axis 25, so that the tower segment connection part 21 can move relative to the frame 10 with the movable support assembly 22. When the tower segment connection part 21 is connected to the tower segment 50, the movement of the tower segment connection part 21 relative to the frame 10 can drive the tower segment 50 to flip and move in the air.

[0057] According to an optional embodiment, the tower segment connection 21 can be connected to the end flange of the tower segment 50, but is not limited thereto. Since the sidewall of the tower segment 50 is relatively thin and the end flange has good structural strength, connecting by means of the end flange of the tower segment 50 can prevent the tower segment 50 from twisting, deforming or even tearing.

[0058] Reference Figure 3 and Figure 4 To prevent deformation of the tower segment 50 during transportation, hoisting, or flipping, a support plate 24 is typically connected to the end of the tower segment 50. For example, but not limited to, this support plate 24 can be connected to the end flange of the tower segment 50. The tower segment connecting part 21 provided in this embodiment can be connected to the end flange of the tower segment 50 via the support plate 24. The support plate 24 supports the end flange of the tower segment 50, thereby preventing deformation of the tower segment 50. During the movement and flipping of the tower segment 50, the support plate 24 supports both ends of the tower segment 50. During the flipping process of the tower segment 50, both ends of the tower segment 50 can rotate synchronously, thereby preventing the tower segment 50 from twisting and deforming.

[0059] Continue to refer to Figure 4 Specifically, the support plate 24 is provided with a first connecting hole 241 for connecting to the end flange of the tower segment 50 and a second connecting hole 242 for connecting to the tower segment connecting part 21. As an example, the support plate 24 can be a long strip plate structure, the first connecting hole 241 can be provided at both ends of the support plate 24 along its length, and the second connecting hole 242 can be provided in the middle of the support plate 24 along its length, but is not limited thereto. The two ends of the support plate 24 can be connected to the end face of the tower segment 50 through the first connecting hole 241 and fasteners, respectively, and the middle of the support plate 24 can be connected to the tower segment connecting part 21 through the second connecting hole 242 and fasteners.

[0060] The first connecting hole 241 can be a circular hole. Multiple first connecting holes 241 can be provided at both ends of the support plate 24 to accommodate tower segments 50 with different diameters, thereby improving the versatility of the support plate 24, but this is not a limitation. In an optional embodiment, the first connecting hole 241 can be an oblong hole (not shown in the figure) to accommodate tower segments 50 with different diameters.

[0061] Continue to refer to Figure 3The diagram shows the usage state of the tower segment connection part 21 connected to the support plate 24. Specifically, the tower segment connection part 21 is provided with a support unit connection hole 211 corresponding to the second connection hole 242. By passing fasteners through both the support unit connection hole 211 and the second connection hole 242, the support plate 24 can be connected to the tower segment connection part 21. Since the tower segment 50 is connected to the support plate 24, the tower segment 50 is connected to the tower segment connection part 21.

[0062] Furthermore, the movable support assembly 22 supports the tower segment connection portion 21. The bottom end of the movable support assembly 22 is movably connected to the frame 10, and the tower segment connection portion 21 is rotatably connected to the movable support assembly 22. Specifically, the movable support assembly 22 includes a first support unit 221 and a second support unit 222. The bottom end of the second support unit 222 is movably connected to the frame 10, and the first support unit 221 is connected between the top end of the second support unit 222 and the tower segment connection portion 21. The tower segment connection portion 21 is rotatably connected to the first support unit 221 and can move relative to the frame 10 along with the second support unit 222.

[0063] Specifically, the first support unit 221 includes a support portion 2211, to which the tower segment connecting portion 21 is rotatably connected. Figure 1 The first support unit 221 is generally formed as an L-shaped plate, including a base 2212 and a support portion 2211. The base 2212 extends generally in a horizontal plane, and the support portion 2211 extends vertically upward from the base. Figure 2 The support portion 2211 provided in this disclosure is mainly used to support the tower segment connection portion 21. For example, but not limited to, the tower segment connection portion 21 is rotatably connected to the support portion 2211 via a pivot shaft 25. Continuing to refer to... Figure 1 The second support unit 222 is movably disposed on the frame 10 along the second horizontal direction Y relative to the frame 10, and the first support unit 221 is movably disposed on the second support unit 222 along the first horizontal direction X, so that the first support unit 221 can move relative to the frame 10 in the entire horizontal plane, wherein the first horizontal direction X is perpendicular to the second horizontal direction Y.

[0064] In this embodiment, the second support unit 222 is generally a horizontal support plate, and the base 2212 is movably disposed on the second support unit 222 along the first horizontal direction X. This allows the first support unit 221 to be movably disposed on the second support unit 222 along the first horizontal direction X. When the tower segment 50 is connected to the tower segment connecting portion 21, the tower segment 50 can move relative to the frame 10 in the entire horizontal plane along with the first support unit 221. In fact, the second support unit 222 is used to support the base 2212, enabling the base 2212 to be stably connected to the second support unit 222, that is, stably connected to the frame 10.

[0065] In order to drive the first support unit 221 to move relative to the second support unit 222, the movable support assembly 22 further includes a first horizontal movement drive unit 223 connected between the first support unit 221 and the second support unit 222, and capable of driving the first support unit 221 to move relative to the second support unit 222 along a first horizontal direction X. In an optional embodiment, the first horizontal movement drive unit 223 includes a lead screw assembly, with a lead screw nut fixed to the first support unit 221, the lead screw rotatably connected to the second support unit 222, and the lead screw nut sleeved on the outside of the lead screw. The lead screw extends along the first horizontal direction X, and during the rotation of the lead screw around its own axis, the lead screw nut will carry the first support unit 221 to move relative to the second support unit 222 along the first horizontal direction X.

[0066] To facilitate the rotation of the lead screw, in this embodiment, a lead screw handle may also be provided at the end of the lead screw, for example, but not limited to, the lead screw handle is provided on the outside of the second support unit 222 for easy operation.

[0067] This embodiment uses the first horizontal movement drive unit 223, which includes a lead screw assembly, as an example for illustration, but it is not limited thereto. The first horizontal movement drive unit 223 can also be a telescopic cylinder.

[0068] To further improve the movable range of the second support unit 222, in this embodiment, the second support unit 222 is vertically movably connected to the frame 10 relative to the frame 10. In an optional embodiment, the movable support assembly 22 further includes a lifting drive, which is retractably connected between the frame 10 and the movable support assembly 22 to drive the movable support assembly 22 to move up and down relative to the frame 10.

[0069] Specifically, the lifting drive can be located below the second support unit 222 to drive the second support unit 222 to move vertically relative to the frame 10. For example, but not limited to, the second support unit 222 can be fixed to the top of the lifting drive, which drives the movable support assembly 22 to move up and down relative to the frame 10, thereby driving the first support unit 221 to move up and down, facilitating the up and down movement of the tower segment 50 connected to the first support unit 221. As an example, the lifting drive can be a telescopic cylinder or a lead screw assembly, but is not limited to these.

[0070] Furthermore, the mobile support assembly 22 also includes a second horizontal movement drive unit 224, which is disposed on the frame 10, for example, but not limited to, at the top of the frame 10. Specifically, the second horizontal movement drive unit 224 includes a telescopic cylinder extending in the second horizontal direction Y. One end of the telescopic cylinder is connected to the frame 10, and the other end is connected to the bottom end of the lifting drive, so that the extension and retraction of the telescopic cylinder drives the lifting drive to move relative to the frame 10 in the second horizontal direction Y, thereby driving the tower segment 50 to move in the second horizontal direction Y.

[0071] The movable support assembly 22 includes a second horizontal movement drive unit 224, a lifting drive, and a first horizontal movement drive unit 223. The second horizontal movement drive unit 224 is connected between the frame 10 and the lifting drive, enabling it to drive the lifting drive to move relative to the frame 10 along a second horizontal direction Y. In an optional embodiment, the second horizontal movement drive unit 224 is a telescopic cylinder, connected between the top end of the frame 10 and the bottom end of the lifting drive. As an example, the bottom end of the lifting drive is connected to either the cylinder body or the lever of the second horizontal movement drive unit 224, and the other is connected to the frame 10.

[0072] The lifting drive extends roughly vertically, and its bottom end can be connected to either the cylinder or the lever of the second horizontal movement drive unit 224, allowing the lifting drive to move relative to the frame 10 along the second horizontal direction Y. The second support unit 222 is connected to the top of the lifting drive, and the lifting drive drives the second support unit 222 to move up and down relative to the frame 10.

[0073] The first support unit 221 can be disposed above the second support unit 222, and a first horizontal movement drive unit 223 is disposed between the first support unit 221 and the second support unit 222 to drive the first support unit 221 to move relative to the second support unit 222 along the first horizontal direction X. Thus, the first support unit 221 in the movable support assembly 22 provided in this disclosure can move relative to the frame 10 along the second horizontal direction Y, and at least one of the longitudinal direction and the first horizontal direction X, so that the tower segment connecting part 21 connected to the first support unit 221 can move, thereby driving the tower segment 50 to move to a predetermined position.

[0074] To improve the mobility reliability of the movable support assembly 22, a guide rail is provided on the top of the frame 10, and a guide groove matching the guide rail is provided at the bottom of the lifting drive, and the assembly is movably mounted on the guide rail, allowing the movable support assembly 22 to move along the guide rail on the frame 10, but this is not a limitation. Alternatively, a guide rail may be provided on the top of the second support unit 222, and a guide groove matching the guide rail may be provided on the first support unit 221, allowing the first support unit 221 to move relative to the second support unit 222 under the guidance of the guide rail.

[0075] To improve the connection reliability of the tower segment 50, the tower segment connecting part 21 includes a mating surface that can be connected to the end flange of the tower segment 50. The support part 2211 extends parallel to the mating surface and is spaced apart from the tower segment connecting part 21 along the first horizontal direction X. In this way, by spaced apart from the tower segment connecting part 21, the tower segment connecting part 21 can rotate relative to the support part 2211, avoiding motion interference between the tower segment connecting part 21 and the support part 2211. This facilitates the tower segment connecting part 21 to drive the tower segment 50 to rotate relative to the support part 2211, thereby driving the tower segment 50 to flip to a suitable angle.

[0076] In order to drive the tower segment connection 21 to rotate, the slewing support 20 also includes a rotation drive assembly 23, which is connected between the tower segment connection 21 and the movable support assembly 22, so as to drive the tower segment connection 21 to rotate relative to the movable support assembly 22.

[0077] return Figure 1 The support plate 24 connected to the end of the tower segment 50 can be connected to the tower segment connecting part 21 by fasteners, and then the tower segment connecting part 21 is driven to rotate around the pivot axis 25 by the rotation drive assembly 23, thereby causing the support plate 24 and the tower segment 50 connected to the support plate 24 to rotate relative to the frame 10.

[0078] Continue to refer to Figures 1 to 3The rotary drive assembly 23 includes a drive wheel 232 and a driven wheel 233. The drive wheel 232 is rotatably connected to the support part 2211, and the driven wheel 233 is rotatably connected to the support part 2211. The driven wheel 233 is fixedly connected to the tower segment connection part 21. The drive wheel 232 can drive the driven wheel 233 to rotate, thereby driving the tower segment connection part 21 to rotate, so that the drive wheel 232 can drive the tower segment connection part 21 to rotate, so as to flip the tower segment 50 connected to the tower segment connection part 21.

[0079] Reference Figure 5 This embodiment uses a gear as an example, where both the driving wheel 232 and the driven wheel 233 are gears and mesh with each other. This meshing transmission improves the rotational accuracy of the driven wheel 233. Alternatively, the driving wheel 232 and the driven wheel 233 can be pulleys, and the rotary drive assembly 23 includes a conveyor belt disposed between the driving wheel 232 and the driven wheel 233. During the rotation of the driving wheel 232, the conveyor belt can be driven to rotate, thereby driving the driven wheel 233 to rotate. In an optional embodiment, the driving wheel 232 and the driven wheel 233 can also be sprockets, and the rotary drive assembly 23 includes a chain disposed between the driving wheel 232 and the driven wheel 233. During the rotation of the driving wheel 232, the chain can be driven to rotate, thereby driving the driven wheel 233 to rotate.

[0080] In this embodiment, the rotary drive assembly 23 is disposed between the support portion 2211 and the tower segment connection portion 21 in the first horizontal direction X, but is not limited thereto.

[0081] In this embodiment, the driven wheel 233 is rotatably connected to the support portion 2211 via the pivot shaft 25, and the tower segment connection portion 21 is fixedly connected to the driven wheel 233 to rotate together with the driven wheel 233. Furthermore, the rotation drive assembly 23 also includes a drive motor 231, and the driving wheel 232 is fixed to the output shaft of the drive motor 231, with the axis of the output shaft being parallel to the axis of the pivot shaft 25.

[0082] Furthermore, in this embodiment, the driven wheel 233 is rotatably sleeved on the outside of the pivot shaft 25. In an optional embodiment, a rolling element is also provided between the driven wheel 233 and the pivot shaft 25, so that the driven wheel 233, the pivot shaft 25 and the rolling element form a bearing structure, but this is not a limitation.

[0083] After the tower segment 50 is flipped to a predetermined angle, in order to prevent the tower segment 50 from accidentally shaking or deflecting, the segmented tower assembly device also includes a locking component 30 for locking the tower segment 50 at a predetermined angle. The locking component 30 can be connected to the end flange of the tower segment 50.

[0084] Continue to refer toFigures 1 to 3 The locking assembly 30 includes a first locking part 31 and a second locking part 32. The first locking part 31 is rotatably connected to the frame 10, and the second locking part 32 is fixed to the frame 10 and is spaced apart from the first locking part 31 along the second horizontal direction Y.

[0085] This embodiment uses the first locking part 31, which includes a locking rod, as an example. One end of the locking rod is rotatably connected to the frame 10, and the other end is provided with a rod connection hole. When a fastener passes through both the rod connection hole and the flange hole of the end flange of the tower segment 50, the first locking part 31 can be connected to the tower segment 50. The second locking part 32 is provided with a connection hole. By having a fastener pass through both the connection hole and another flange hole of the end flange of the tower segment 50, the tower segment 50 can be connected to the second locking part 32. By connecting the end flange of the tower segment 50 to the first locking part 31 and the second locking part 32 respectively, this disclosure can lock the tower segment 50 at the predetermined position, thereby improving the reliability of the segmented tower assembly device.

[0086] In an optional embodiment, the first locking part 31 can be a telescopic rod with adjustable length, thereby adjusting the length of the first locking part 31 according to the angle and position of the tower segment to achieve connection with the tower segment 50.

[0087] In this embodiment, in order to avoid uneven local stress on the tower segment 50, the locking component 30 can be directly connected to the support plate 24, thereby eliminating the need for the locking component 30 to be directly connected to the end flange of the tower segment 50, reducing the risk of local deformation of the tower segment 50.

[0088] Because the tower segment 50 is relatively heavy, in order to overcome its gravity and prevent deformation under its own weight, the segmented tower assembly device also includes a bottom support 40 to support the wall of the tower segment 50. This wall can be a wall facing the ground, such as... Figure 1 As shown, the bottom support 40 is spaced apart from the slewing support 20 along the first horizontal direction X. For example, but not limited to, the bottom support 40 can support the middle part of the tower segment 50 in the length direction.

[0089] Continue to refer to Figures 1 to 3 The bottom support 40 includes a lifting platform 41 and a support roller 42. The lifting platform 41 is movably connected to the frame 10, and the support roller 42 is rotatably connected to the lifting platform 41. As an example, the axis of rotation of the support roller 42 is generally parallel to the pivot axis 25, but is not limited thereto.

[0090] In this embodiment, the lifting platform 41 is vertically connected to the frame 10. For example, but not limited to, the bottom support 40 also includes a lifting platform drive unit 43, which extends longitudinally and whose two ends are respectively connected to the lifting platform 41 and the frame 10. As an example, the lifting platform drive unit 43 can be a telescopic cylinder, with its two ends respectively connected to the lifting platform 41 and the frame 10. By extending and retracting the telescopic cylinder, the lifting platform 41 can be raised or lowered relative to the frame 10, thereby providing support under the tower section 50.

[0091] To prevent the bottom support 40 from scratching the tower segment 50 when it comes into contact with the tower segment 50, in this embodiment the bottom support 40 includes a support roller 42 disposed above the lifting platform 41. The support roller 42 can be cylindrical. When the support roller 42 abuts against the bottom wall of the tower segment 50, the axis of rotation of the support roller 42 is parallel to the axis of the tower segment.

[0092] In this embodiment, when the tower segment 50 is locked at a predetermined angle by the locking component 30, the position of the tower segment 50 relative to the bottom support 40 can be adjusted by moving the support component 22 so that the tower segment 50 can be located above the support roller 42. Then, the height of the support roller 42 can be adjusted by the lifting platform drive unit 43 until the support roller 42 is in contact with the wall of the tower segment 50, thereby achieving support for the tower segment 50.

[0093] Reference Figure 6 and Figure 7 After the first tower segment is locked by the first locking part 31 and the second locking part 32 and set on the bottom support 40, the tower segment connecting part 21 can be separated from the end flange of the tower segment 50. The position of the moving support assembly 22 relative to the frame 10 is adjusted to connect the tower segment connecting part 21 to the second tower segment. Then, the angle and position of the second tower segment are adjusted so that the second tower segment is aligned with the first tower segment and connected to each other. In the case of a segmented tower comprising three tower segments, the first tower segment can be positioned on the left side of the frame 10 using a segmented tower assembly device. Then, the second tower segment can be positioned on the right side of the frame 10 using the same device. The first and second tower segments can be connected to each other, for example, but not limited to, by connecting the first and second tower segments together via a connecting frame 26. Finally, the third tower segment can be directly lifted using a lifting device and connected to the first and second tower segments to complete the tower assembly operation.

[0094] Reference Figure 8Furthermore, the segmented tower assembly device includes at least two slewing supports 20, which are spaced apart along the second horizontal direction Y. Each slewing support 20 can be used to support and rotate a single tower segment 50, so that different tower segments 50 can be moved to a predetermined position and a predetermined angle by the cooperation of the two slewing supports 20, thereby facilitating the assembly of the tower segments 50.

[0095] Reference Figure 9 The assembly method of the segmented tower provided in the first exemplary embodiment of this disclosure is particularly applicable to segmented towers having three or more tower segments 50. For ease of description, the example of a segmented tower including three tower segments 50 having the same central angle will be used for illustration.

[0096] First, the first tower segment 51 is lifted with its opening facing downwards and connected to the tower segment connecting part 21. Then, the tower segment connecting part 21 is driven to rotate relative to the movable support assembly 22, thereby rotating the first tower segment 51 to a first rotation angle, such as, but not limited to, ... Figure 1 As shown by the middle arrow, the tower segment connecting part 21 is driven to rotate counterclockwise by 150° (as shown by the arrow in the figure), and then the moving support assembly 22 is driven to rotate and move horizontally relative to the frame 10 (for example, horizontally to the right, as shown by the arrow in the figure) until the first tower segment 51 is above the support roller 42. Then, the tower segment connecting part 21 is driven to rotate clockwise by 30° (as shown by the arrow in the figure), and then the end flange of the first tower segment 51 is connected to the locking assembly 30. For example, but not limited to, the circumferential ends of the end flange of the first tower segment 51 are respectively connected to the first locking part 31 and the second locking part 32. Then, the lifting platform 41 is driven to move upward (as shown by the arrow in the figure) until the support roller 42 abuts against the bottom wall of the first tower segment 51. For example, but not limited to, the bottom wall can be the wall of the first tower segment 51 facing the ground. After the above operation, the first tower segment 51 can maintain this angle and be reliably supported above the support roller 42.

[0097] Then, the first tower segment 51 is removed from the tower segment connection part 21 in preparation for the connection of the second tower segment 52. The above operation can be repeated to flip and move the second tower segment 52. The difference is that after the second tower segment 52 is connected to the tower segment connecting part 21 with the opening facing downward, the tower segment connecting part 21 can be driven to rotate 150° clockwise relative to the moving support assembly 22. Then, the moving support assembly 22 is driven to rotate and move horizontally relative to the frame 10 (for example, horizontally to the left) until the first tower segment 51 is above the support roller 42. Then, the tower segment connecting part 21 is driven to rotate 30° counterclockwise relative to the moving support assembly 22. Then, the circumferential ends of the end flange of the second tower segment 52 are respectively connected to the first locking part 31 and the second locking part 32 to lock the second tower segment 52 at the predetermined position. At this time, the two sides of the first tower segment 51 and the second tower segment 52 that are close to each other can be assembled and fixed. The above operation completes the flipping and movement of the second tower segment 52.

[0098] To further improve the connection reliability of the first tower segment 51 and the second tower segment 52, after the assembly and fixing of the adjacent ends of the first tower segment 51 and the second tower segment 52 are completed, the connecting frame 26 is then connected to the far circumferential ends of the end flanges of the first tower segment 51 and the second tower segment 52.

[0099] Finally, the third tower segment 53 is lifted with the opening facing downwards, and then assembled and fixed with the first tower segment 51 and the second tower segment 52 respectively, thus completing the assembly of the segmented tower.

[0100] Reference Figure 10 The assembly method for a segmented tower provided in the second exemplary embodiment of this disclosure is particularly applicable to segmented towers having three or more tower segments 50. For ease of description, the example of a segmented tower including three tower segments 50 having the same central angle will be used for illustration.

[0101] In addition, the segmented tower assembly device used in this embodiment includes two slewing supports 20. For ease of description, the slewing support 20 located on the left side of the frame 10 is named the first slewing support, and the slewing support 20 on the right side of the displacement frame 10 is named the second slewing support.

[0102] Unlike the assembly method of the segmented tower provided in the first exemplary embodiment, in this embodiment, after locking the first tower segment 51 at a predetermined angle, it is not necessary to remove the first tower segment 51 from the tower segment connection part 21 of the first slewing support 20. Instead, the second tower segment 52 can be connected to the tower segment connection part 21 of the second slewing support 20.

[0103] Reference Figure 11 The assembly method for a segmented tower provided in the third exemplary embodiment of this disclosure is particularly applicable to a segmented tower having two tower segments 50, namely a first tower segment 51 and a second tower segment 52, wherein the central angle of the first tower segment 51 is smaller than the central angle of the second tower segment 52. In this embodiment, the central angle of the first tower segment 51 is 120° and the central angle of the second tower segment 52 is 240° as an example, but it is not limited thereto.

[0104] Specifically, the assembly method of the segmented tower includes the following steps: First, the first tower segment 51 can be lifted with the opening facing downwards and connected to the tower segment connecting part 21. Then, the tower segment connecting part 21 can be driven to rotate relative to the movable support assembly 22 to a predetermined angle. For example, but not limited to, the tower segment connecting part 21 can be driven to rotate counterclockwise 180° relative to the movable support assembly 22 until the opening of the first tower segment 51 faces upwards. Then, the movable support assembly 22 can be driven to move relative to the frame 10 to a predetermined position and lock the first tower segment 51 at the predetermined position. As shown by the arrow in the figure, the movable support assembly 22 is moved horizontally to the right to the middle position of the frame 10 and the first tower segment 51 is locked. Then, the lifting platform 41 can be driven to move upwards to support the bottom wall of the first tower segment 51. Finally, the second tower segment 52 is lifted with the opening facing downwards and assembled with the first tower segment 51.

[0105] Reference Figure 12 The assembly method for a segmented tower provided in the fourth exemplary embodiment of this disclosure is particularly applicable to a segmented tower having two tower segments 50, namely a first tower segment 51 and a second tower segment 52, wherein the central angle of the first tower segment 51 is greater than the central angle of the second tower segment 52. In this embodiment, the central angle of the first tower segment 51 is 240° and the central angle of the second tower segment 52 is 120° as an example, but this is not a limitation.

[0106] Specifically, the assembly method of the segmented tower includes the following steps: First, the first tower segment 51 can be lifted with the opening facing upwards and placed on the support roller 42. The first tower segment 51 will be adjusted and balanced under the action of gravity. Then, the second tower segment 52 is lifted with the opening facing downwards and assembled with the first tower segment 51.
