[0047] 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.

[0048] Reference Figures 1 to 4 This disclosure provides a tower transport fixture for supporting tower sections. The tower transport fixture includes a base 1 and a support unit. The support unit includes a support 2 and an adapting block 3. The support 2 is supported on the base 1 and has at least two adjustment holes 21 that match the bolt holes of the end flange 9. The adapting block 3 is detachably connected to the side of the support 2 facing away from the end flange 9. The adapting block 3 has a connecting hole 34 that aligns with the adjustment holes 21. The tower transport fixture can be connected to the end flange 9 by fasteners.

[0049] This disclosure provides support and fixation for the tower section 7 by placing the tower transport fixture on the end flange 9 of the tower section 7, thereby preventing deformation of the opening of the end flange 9 of the tower section 7.

[0050] The bolt hole alignment of the adapting block 3 and the end flange 9 provided in this disclosure allows for the alignment of the connecting hole 34 with the bolt hole when the tower transport fixture is used to support tower pieces 7 of different specifications. This improves the versatility of the tower transport fixture. In other words, the tower transport fixture provided in this disclosure can include multiple adapting blocks 3, with different distances between adjacent connecting holes 34 on different adapting blocks 3 or different diameters of individual connecting holes, so as to accommodate different end flanges 9.

[0051] The tower transport fixture provided in this disclosure can be applied to the transport or assembly of tower sections with the same tower section diameter but different flange pitch circle diameters or different numbers of bolts, thereby improving the versatility of the tower transport fixture.

[0052] The tower transport fixtures provided in this disclosure are usually installed in pairs. A pair of tower transport fixtures are respectively supported at both ends of the axial direction of the tower segment. The tower transport fixture at the bottom end of the axial direction of the tower segment and the tower transport fixture at the top end of the axial direction of the tower segment have the same structure. For ease of description, this disclosure takes the tower transport fixture installed at the top end of the axial direction of the tower segment as an example.

[0053] Furthermore, considering that during transportation, if the friction connection fails due to insufficient preload or overload, the bolts will be subjected to shearing action. If the tower plate 7 is continued to be fixed, the fasteners will be subjected to bending moment overload and fail, posing a safety hazard. Therefore, in order to improve the versatility and reliability of the tower transportation fixture, this disclosure also provides a tower transportation fixture provided by an exemplary embodiment, wherein the adjustment hole 21 has a predetermined arc length and radius, and the side of the adapting block 3 facing the support 2 is provided with a boss 32 that matches the adjustment hole 21, and the boss 32 is inserted into the adjustment hole 21.

[0054] By setting the adjustment hole 21 to have a predetermined arc length and radius, it is easy to align with the bolt holes on the end flange 9, thus improving the assembly efficiency of the tower transport tooling and reducing transportation costs to a certain extent.

[0055] Furthermore, in the connection between the tower transport fixture and the tower plate, to ensure sufficient contact between the support 2 and the tower plate for better load-bearing capacity, the tower transport fixture provided in this disclosure features a boss 32 on the adapting block 3. The circumferential edge of the boss 32 fits against the wall of the adjusting hole 21, preventing the fastener from directly bearing shear force. When the tower transport fixture supports the tower plate 7, the boss 32 is fitted around the outer periphery of the fastener, preventing the fastener from directly contacting the hole wall of the support 2 and bearing shear force, thereby improving the service life of the fastener and thus improving the reliability of the tower transport fixture.

[0056] This disclosure improves the reliability of tower transport fixtures by setting up boss 32 to prevent fasteners from bearing shear force alone.

[0057] As an example, in this embodiment, each support 2 is provided with two adapting blocks 3, and the two adapting blocks 3 are respectively provided at both ends of the support 2 along the circumferential direction of the tower piece 7.

[0058] As an example, the boss 32 extends from the side of the adapting block body 33 facing the bracket 2, and a step is provided between the bosses 32. The outer peripheral wall of the boss 32 fits against the hole wall of the adjustment hole 21, and the step fits against the side wall of the bracket 2 so that the adapting block 3 and the bracket 2 are in full contact.

[0059] This disclosure increases the contact area between the adapting block 3 and the support 2 by setting steps, thereby improving the connection reliability of the tower transport tooling. The support 2 can not only be subjected to radial force along the tower piece 7, but also to axial force along the tower piece 7, thus providing reliable support for the tower piece 7.

[0060] In this embodiment, the adapting block 3 and the support 2 can be detachably connected. Specifically, the adapting block 3 has a first connecting hole 31 in its center, and the support 2 has a mounting hole for the adapting block connecting portion 27 that aligns with the first connecting hole 31. By connecting fasteners to the first connecting hole 31 and the mounting hole, the adapting block 3 can be attached to the support 2. This prevents the adapting block 3 and the support 2 from scattering and being lost, improving the reliability of the tower transport tooling.

[0061] Furthermore, in this embodiment, the adapting block 3 and the support 2 are connected to avoid excessive and difficult-to-manage materials on site. The tower transport fixture can be pre-assembled, and at the connection site of the tower piece 7, there is no need to disassemble other components, especially the adapting block 3. Fasteners are simply passed through the connection hole 34 to connect to the end flange 9. The adapting block 3 and the support 2 are detachably connected, which facilitates the replacement of different adapting blocks 3 to adapt to different projects, further improving the versatility of the tower transport fixture.

[0062] The disclosed adaptable block 3 is detachably connected to the support 2, which greatly facilitates on-site material management, avoids separate handling, and facilitates the recycling and reuse of tower transport equipment.

[0063] Continue to refer to Figures 1 to 4 In this embodiment, the adjusting hole 21 has a predetermined arc length and radius, and the arc length of the adjusting hole 21 is sufficient to align with at least two adjacent bolt holes of the end flange 9. Thus, when installing the tower transport fixture, the adjusting hole 21 can be aligned with a complete set of bolt holes on the end flange 9, allowing fasteners to be connected between the adjusting hole 21 and the tower piece 7 without excessive adjustments, thereby improving the assembly efficiency of the tower transport fixture.

[0064] Specifically, refer to Figure 4 and Figure 5 The inner ring of the adjusting hole 21 is located inside the flange pitch circle, and the difference between the flange pitch circle radius and the inner ring radius of the adjusting hole 21 is the bolt radius.

[0065] Dm=Da-2dk-2t, that is, Dm=Da-2(dk+t),

[0066] The minimum flange pitch circle diameter of end flange 9 is:

[0067] Dm min =Da-2(dk) max +tmax )

[0068] Inner radius R of the adjustment hole N satisfy:

[0069] R Nmin =Dm min / 2-d max / 2 is equivalent to 2R Nmin =Dm min -d max =Da-2(dk) max +t max )-d max

[0070] We can obtain,

[0071] R N ≥R Nmin =Da / 2-d max / 2-dk max -t max ;

[0072] Where Da is the outer diameter of the tower, t is the wall thickness of the tower, dk is the radial construction space dimension of the bolt, and d is the bolt diameter.

[0073] Furthermore, the outer ring of the adjusting hole is located outside the flange pitch circle, and the difference between the outer ring radius of the adjusting hole and the flange pitch circle radius is the bolt radius.

[0074] The maximum flange pitch circle diameter of end flange 9 is:

[0075] Dm max =Da-2(dk) min +t min )

[0076] Adjusting hole outer radius R W satisfy:

[0077] R W ≤R Wmax =Da / 2-d min / 2-dk nin -t min ;

[0078] Where Da is the outer diameter of the tower, t is the wall thickness of the tower, dk is the radial construction space dimension of the bolt, and d is the bolt diameter.

[0079] The arc length L of the adjusting hole satisfies:

[0080] L = c + d leads to L = πDm / N + d;

[0081] Pushed,

[0082] Lmin =πDm min / N+d max =π{Da-2(dk) max +t max )} / N+d max

[0083] Right now,

[0084] L≥L min =π / N(Da-2dk) max -2t max )+d max ,

[0085] Where Da is the outer diameter of the tower, N is the number of bolt holes on the flange at the end of the tower; t is the tower wall thickness, dk is the radial construction space dimension of the bolts; L is the arc length of the adjustment hole, d is the bolt diameter, and Dm is the flange pitch circle diameter.

[0086] In this embodiment, N represents the number of bolts, where N ≥ 2. The two adjustment holes 21 on the bracket 2 provided in this disclosure can each be connected to at least one flange pitch bolt.

[0087] To further improve the versatility of tower transport tooling, refer to Figure 6 The tower transport fixture includes at least two support units, which are stacked longitudinally, with each support unit supporting one tower segment 7, but not limited thereto.

[0088] Specifically, each support unit has a first connecting part 24 and a second connecting part 25 at opposite ends of its support 2. The first connecting part 24 of the support 2 can be connected to the second connecting part 25 of the adjacent support 2.

[0089] By stacking at least two support units vertically, multiple tower sections 7 can be supported within a unit area, reducing the floor space required, improving the efficiency of a single trip, reducing the number of trips, and thus reducing the tower assembly cost to some extent.

[0090] To further improve the assembly efficiency of adjacent support units, the first connecting part 24 has a first inclined surface 28, which extends inclinedly along the direction from one end of the support 2 to the other end, and the second connecting part 25 has a second inclined surface 29 that matches the first inclined surface.

[0091] Reference Figure 6 and Figure 7When the first support 2-1, located above, moves downward to connect with the second support 2-2 below, the first inclined surface 28 slides along the second inclined surface 29 until the first connecting part 24 is stably supported on the second connecting part 25. In this embodiment, the first inclined surface 28 and the second inclined surface 29 serve as guides between adjacent supports 2, improving the assembly efficiency of the tower transport fixture.

[0092] Furthermore, to avoid installation interference between longitudinally adjacent supports 2, the tower transport fixture also includes a back plate 5. The back plate 5 is located on the side of the support 2 facing the end flange 9. The back plate 5 is provided with a back plate connection hole 51 that is aligned with the adjustment hole 21. This can prevent interference between the end flange 9 of one tower piece 7 and the support 2 of the adjacent tower piece 7 when adjacent tower pieces 7 are stacked, thus improving assembly efficiency.

[0093] As an example, the back plate connection hole 51 matches the boss 32, and the outer peripheral wall of the boss 32 fits against the hole wall of the back plate connection hole 51, but this is not a limitation.

[0094] During the assembly of tower sections, holes are left between the multiple tower transport tools located at the top of the tower sections to facilitate the climbing of operators during assembly.

[0095] The strapping function is to prevent the overall shift of segments during transportation, thereby improving safety. Strapping points are reserved on the transport support.

[0096] Continue to refer to Figure 6 Furthermore, the tower transport fixture provided in this disclosure also includes a turning fixture 8 for rotating and assembling the tower pieces 7. In this embodiment, each tower transport fixture can be equipped with a corresponding turning fixture 8, which makes the installation interface accuracy easy to control, avoids the coupling of multiple components, and improves installation efficiency. The turning fixture 8 is set on the top support unit of the three stacked support units, but is not limited thereto.

[0097] The tower base transport fixture disclosed herein can enable the rapid installation of the turning fixture when multiple tower sections 7 are stacked.

[0098] In the stacked state, operators can only install the flipping fixture 8 from one side of the support, which is space-constrained and makes installation difficult. To facilitate the assembly of the flipping fixture 8, the support has hand holes 20 near the bolts for installing the flipping fixture, allowing operators to install the fasteners between the flipping fixture 8 and the support 2. In addition, to prevent the bolts from rotating when torque is applied, a limit structure is provided on the other side of the support.

[0099] For T-type flanges, due to the large diameter of the outer ring, some of the installation holes of the turning tool will be blocked, making it impossible to install on one side.

[0100] Install the top two unobstructed bolts beforehand, apply full torque, then lift the tower section to about 7.5 meters, then install the bottom two bolts. After installation, begin the turning process.

[0101] By directly drilling threads on the bracket, the problem of the 8-piece turning tool being able to be operated from only one side is solved, and no hand hole is needed.

[0102] Nuts or bolts are pre-installed on the back of the bracket to solve the problem that the installation and turning tool 8 can only be operated from one side, and no hand hole is needed.

[0103] The tower transport tooling provided in this disclosure is highly versatile and can meet the needs of different flange pitch circles and bolt numbers for tower sections of the same diameter, thereby enabling the reuse of tower transport tooling for different projects.

[0104] The tower transport fixture provided in this disclosure can be used to support tower sections. During the transport of tower sections, the tower transport fixture can support individual tower sections, which can prevent deformation of the tower section openings and thus improve the current assembly efficiency.

[0105] Furthermore, the tower transport fixture provided in this disclosure includes at least two support units, which can be stacked longitudinally to form a detachable connection. Each support unit can support a corresponding tower piece 7. In this way, multiple support units support multiple tower pieces, reducing the floor space occupied and thereby improving the efficiency of a single transport trip, which to some extent reduces the tower assembly cost.

[0106] The tower transport fixture provided in this disclosure has an adjustment hole 21 on the support 2. The adjustment hole 21 is configured to have a predetermined arc length and radius, and can pass through two adjacent bolts at the same time. It can be used to support tower pieces 7 of various specifications with different flange pitch circles and different numbers of bolts under the same tower diameter, thereby improving the versatility of the tower transport fixture to be applicable to different projects and reducing the transportation cost of the tower.

[0107] Specifically, in different projects, the tower diameter is the same, but the flange pitch circle is different, and the number and specifications of bolts are also different.

[0108] In addition, the tower transport fixture provided in this disclosure can also be used in the assembly process of tower sections. The tower transport fixture also includes a tie rod 6, which is detachably connected to the tie rod connection holes of two adjacent supports. The tower transport fixture is used to position and prevent deformation of adjacent tower sections 7, thereby reducing the difficulty of tower section assembly and improving the assembly efficiency of tower sections.

[0109] The tower transport fixture provided in this disclosure can support the tower section 7 during transport and can also be used for assembling and positioning the tower section 7 during tower assembly, thus improving the versatility of the tower transport fixture.

[0110] During the transportation of tower piece 7:

[0111] The tower transport fixture can meet the needs of stacking or transporting tower sections 7 individually, that is, to support and fix tower sections 7 and prevent excessive deformation of the flange openings of segmented tower sections.

[0112] When used to support multiple tower sections 7 stacked longitudinally, the tower transport fixture can also maintain the spacing between the tower sections 7 to prevent adjacent tower sections 7 from scraping or bumping against each other.

[0113] By setting a back plate 5 between the bracket 2 and the end flange 9, interference can be prevented when the accessories are stacked with the tower piece 7, thereby further improving the assembly efficiency.

[0114] The tower transport fixture provided in this disclosure also includes lifting points 26, which are set on the support 2 to facilitate the rapid handling of individual tower sections 7 and tower sections.
