Description

Technical Field

[0001] This application relates to the field of truss technology, and in particular to a wind power truss device. Background Technology

[0002] In wind power generation equipment, the wind turbine truss is a key load-bearing structure supporting the internal components of the nacelle. With the increasing size of wind turbine units, the size and weight of the truss have increased significantly, placing higher demands on the assembly, transportation, and storage processes during production.

[0003] In existing technologies, the pre-assembly of wind turbine trusses mostly uses fixed, specialized tooling. These devices have poor versatility, can only be adapted to a single product model, resulting in the need for multiple sets of equipment on the production line, large footprint, and low utilization rate. At the same time, the devices lack effective positioning, adjustment, and integrated transfer functions, making it difficult to guarantee assembly accuracy and resulting in low transfer efficiency, which seriously restricts production cycle and layout optimization. Utility Model Content

[0004] The purpose of this application is to provide a wind power truss device that can flexibly adjust the base assembly length and column spacing according to the size requirements of different wind power truss models, thereby improving the versatility of the wind power truss device.

[0005] In a first aspect, this utility model provides a wind turbine truss device, comprising: At least two bases, with adjacent two bases being detachably connected; Multiple columns are detachably mounted on the base, and the top of each column is provided with a support platform for supporting the truss. Multiple positioning plates are provided corresponding to multiple columns. The positioning plates are detachably provided on the side wall of the columns. The positioning plates extend upward along the height direction of the columns to protrude from the support platform. The portion of the positioning plate protruding from the support platform forms a positioning part, which is used to laterally position the truss on the support platform.

[0006] Beneficial effects: When assembling this wind turbine truss device, it is necessary to first select the corresponding number of bases according to the size requirements of the wind turbine truss and connect and fix adjacent bases to complete the overall assembly of the bases; then, according to the truss size, install the columns at the preset positioning points on the bases, and at the same time assemble the positioning plates onto the side walls of the columns, ensuring that the positioning part of the positioning plate protrudes from the support platform at the top of the column. When installing the truss, the truss ends can be placed on the support platform of the column to achieve stable support, and because the positioning part protrudes from the support platform, it can simultaneously form a lateral limit on the truss, ensuring the initial positioning posture of the truss.

[0007] Through a modular design with at least two detachable base connections and detachable connections between columns and bases, the base assembly length and column spacing can be flexibly adjusted according to the size requirements of different wind turbine truss models. This improves the versatility of the wind turbine truss device and breaks the limitation of traditional fixed tooling that is only compatible with a single product model. It eliminates the need to configure multiple sets of equipment for different trusses, reducing equipment investment and workshop floor space, improving tooling utilization, and adapting to the diverse production needs of the wind power industry.

[0008] In addition, the positioning plate's positioning part can provide precise constraints on the truss on the support platform through its lateral positioning function, replacing the traditional manual calibration method and reducing positioning errors. At the same time, the positioning plate and the column are detachably connected, and different specifications of positioning plates can be replaced according to the lateral positioning requirements of the truss, further adapting to diverse truss structures and ensuring the stability of assembly accuracy.

[0009] In one optional embodiment, the positioning plate includes a connecting portion connected to the positioning portion, and the connecting portion has a plurality of connecting holes; The side wall of the column is provided with a mounting part, and the mounting part is provided with mounting holes corresponding to the connecting holes; The connecting part is detachably connected to the mounting part by fasteners passing through the connecting hole and the corresponding mounting hole.

[0010] Beneficial effects: The connection and mounting parts are detachably fitted with fasteners and connecting and mounting holes, supporting quick disassembly and replacement of the positioning plate. When the wind turbine truss model changes or the lateral positioning requirements are adjusted, there is no need to modify the column body; only the corresponding specification positioning plate needs to be replaced to adapt to the lateral constraint requirements of different trusses. This avoids the high cost of replacing the entire column required by traditional welding or fixed connections, further enhancing the versatility of the device.

[0011] In one optional embodiment, the positioning part is further provided with a plurality of positioning holes for connecting with the truss.

[0012] Beneficial effects: The positioning holes can be precisely aligned with the pre-set holes of the truss. Through the use of positioning pins, bolts and other fasteners, the truss and the positioning part are rigidly constrained, avoiding the truss displacement or swaying that may occur with traditional lateral limiting.

[0013] In one optional embodiment, the column further includes an adjustment plate, which is detachably mounted on the support platform and is used to adjust the height of the bearing surface of the support platform.

[0014] Beneficial effects: The adjustable plates can be added or removed in number or changed to different thicknesses to precisely adjust the bearing surface height of the support platform without modifying the column itself, thus adapting to the differences in bottom support height of different wind turbine truss models. For example, for trusses with slightly lower heights, thicker adjustable plates can be added to raise the bearing surface; for trusses with higher heights, the adjustable plates can be removed to lower the height, perfectly meeting the assembly needs of various truss types and further enhancing the universal adaptability of the device.

[0015] In one optional embodiment, the bottom of the column is provided with a base plate, the base plate is provided with a plurality of through holes, and the base is provided with through holes corresponding to the through holes; The column is detachably connected to the base by fasteners passing through the through hole and the corresponding through hole.

[0016] Beneficial effects: Multiple sets of through holes can be pre-set along the length of the base. When the size of the wind turbine truss changes and the column spacing needs to be adjusted, there is no need to modify the base or columns. Simply loosen the fasteners, move the column base plate along the base to the corresponding through hole position, and then re-lock it. This breaks the limitations of traditional fixed installation and can quickly adapt to the column layout requirements of different truss models, further improving the device's compatibility with multi-variety production.

[0017] In one alternative embodiment, the wind turbine truss assembly further includes a clamping member that clamps the base plate and the base, thereby enabling the column to be detachably connected to the base.

[0018] Beneficial effects: The clamping components are fixed by directly clamping the base plate to the base, eliminating the need for aligning holes with fasteners and repeated tightening operations. This allows for quick clamping or loosening of the columns, making it particularly suitable for scenarios involving switching between production of multiple truss models. Compared to traditional bolt connections, it significantly reduces the time required for adjusting or replacing column positions, minimizes production line downtime, and improves the overall assembly pace.

[0019] In one alternative embodiment, the wind turbine truss assembly further includes a connecting plate, through which the ends of two adjacent bases are detachably connected.

[0020] Beneficial effects: The connecting plate can splice multiple bases into a whole of arbitrary length, eliminating the need to customize bases of specific lengths for wind turbine trusses of different spans. For example, 2-3 bases can be spliced ​​together when assembling small trusses, and the number of bases can be increased when assembling large trusses, breaking the limitations of traditional fixed-length bases and greatly improving the device's adaptability to trusses of different sizes.

[0021] In one optional embodiment, the base is further provided with a plurality of crossbeams, which are spaced apart along the length of the base. The crossbeams can move along the length of the base and are fixed in the desired position by locking members. Each crossbeam can be detachably provided with the column.

[0022] Beneficial effects: The crossbeams can move along the length of the base and be fixed by locking devices, allowing for free adjustment of the spacing between adjacent crossbeams according to the support point positions of different wind turbine truss models, thereby changing the installation layout of the columns. Without modifying the base or replacing the crossbeams, it can quickly adapt to differences in truss span and support point positions, significantly improving the accuracy and flexibility of the column layout compared to a fixed crossbeam design.

[0023] In one optional embodiment, the base is provided with a guide groove extending along its length, and the end of the crossbeam is provided with a pulley, which is movably disposed within the guide groove.

[0024] Beneficial effects: When the pulley rolls within the guide groove, it converts the sliding friction between the crossbeam and the base into rolling friction, significantly reducing movement resistance. Operators can easily push the crossbeam along the length of the base to adjust its position without expending much effort. Especially after the crossbeam supports the column, it can still move smoothly, significantly reducing the operator's workload and shortening the position adjustment time.

[0025] In one optional embodiment, the base is provided with at least one hoisting point; The side wall of the column is provided with at least one lug, and the lug is provided with a lifting hole.

[0026] Beneficial effects: The lifting points of the base can be used with cranes, forklifts, and other equipment to achieve the overall lifting of single or multiple sections of the spliced ​​base, eliminating the need for manual handling. This is especially suitable for the relocation of large bases in workshops or for warehouse transport. The lugs on the columns allow for direct hook lifting, facilitating the individual transport of the columns to the base installation location or their rapid disassembly and relocation during maintenance. The combination of these features allows for the disassembly, transport, and on-site reassembly of the various components of the device, solving the problems of difficult transportation and large footprint associated with monolithic tooling.

Detailed Implementation

[0030] In related technologies, the pre-assembly of wind turbine trusses often uses fixed, specialized tooling. These devices have poor versatility, can only be adapted to a single product model, resulting in the need for multiple sets of equipment on the production line, large floor space, and low utilization rate. At the same time, the devices lack effective positioning, adjustment, and integrated transfer functions, making it difficult to guarantee assembly accuracy and resulting in low transfer efficiency, which seriously restricts production cycle and layout optimization.

[0031] In the early stages of research and development, this application proposed a solution combining a spliced ​​base with multiple columns to improve the versatility of wind power truss devices. By adjusting the overall length through base splicing and allowing for detachable connections between the columns and bases to change the spacing, this approach can adapt to the size requirements of different truss models, thus initially overcoming the limitations of traditional fixed fixtures.

[0032] However, the scheme revealed positioning defects in practice. After the truss was placed on the column support platform, it lacked effective lateral constraints and was prone to displacement or swaying. It required repeated manual calibration, which was not only inefficient but also made it difficult to ensure the stability of assembly accuracy, becoming a key issue restricting the practicality of the device.

[0033] Based on this, the inventors of this application have redesigned the wind turbine truss device. When assembling the wind turbine truss device, the corresponding number of bases must first be selected according to the size requirements of the wind turbine truss, and adjacent bases must be connected and fixed to complete the overall assembly of the bases. Then, according to the truss dimensions, columns are installed at preset positioning points on the bases, and positioning plates are simultaneously assembled onto the side walls of the columns, ensuring that the positioning portion of the positioning plate protrudes beyond the support platform at the top of the column. When installing the truss, the truss ends can be placed on the support platform of the column for stable support, and because the positioning portion protrudes beyond the support platform, it can simultaneously provide lateral restraint to the truss, ensuring the initial positioning posture of the truss.

[0034] Through a modular design with at least two detachable base connections and detachable connections between columns and bases, the base assembly length and column spacing can be flexibly adjusted according to the size requirements of different wind turbine truss models. This improves the versatility of the wind turbine truss device and breaks the limitation of traditional fixed tooling that is only compatible with a single product model. It eliminates the need to configure multiple sets of equipment for different trusses, reducing equipment investment and workshop floor space, improving tooling utilization, and adapting to the diverse production needs of the wind power industry.

[0035] In addition, the positioning plate's positioning part can provide precise constraints on the truss on the support platform through its lateral positioning function, replacing the traditional manual calibration method and reducing positioning errors. At the same time, the positioning plate and the column are detachably connected, and different specifications of positioning plates can be replaced according to the lateral positioning requirements of the truss, further adapting to diverse truss structures and ensuring the stability of assembly accuracy.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0037] The following is combined Figures 1 to 11 The following describes embodiments of the present invention.

[0038] According to embodiments of the present invention, on the one hand, such as Figures 1 to 11 As shown, a wind power truss device is provided, including a base 100, a column 200 and a positioning plate 300.

[0039] Specifically, such as Figure 1 As shown, at least two bases 100 are provided, wherein any two adjacent bases 100 can be detachably connected.

[0040] Specifically, such as Figures 1 to 4 As shown, there are multiple columns 200, each of which is detachably mounted on the base 100. Each column 200 has a support platform 210 on its top, which is used to support the truss.

[0041] Specifically, such as Figure 1 , Figure 2 and Figure 6 As shown, multiple positioning plates 300 are provided, and multiple positioning plates 300 are correspondingly arranged with multiple columns 200. Each positioning plate 300 is detachably installed on the side wall of the column 200. Along the height direction of the column 200, the positioning plate 300 extends upward and is higher than the support platform 210, so that the part of the positioning plate 300 protruding from the support platform 210 forms a positioning part 310, which is used to laterally position the truss on the support platform 210.

[0042] When assembling this wind turbine truss device, the following steps are required: First, select the corresponding number of bases 100 according to the size requirements of the wind turbine truss and connect and fix adjacent bases 100 to complete the overall assembly of the bases 100. Then, install the columns 200 at the preset positioning points of the bases 100 according to the truss dimensions, and simultaneously assemble the positioning plates 300 onto the side walls of the columns 200, ensuring that the positioning part 310 of the positioning plate 300 protrudes from the support platform 210 at the top of the column 200. When installing the truss, the ends of the truss can be placed on the support platform 210 of the column 200 for stable support. Since the positioning part 310 protrudes from the support platform 210, it can simultaneously form a lateral limit on the truss, ensuring the initial positioning posture of the truss.

[0043] Through a modular design that allows for the detachable connection of at least two bases 100 and the detachable connection of the columns 200 to the bases 100, the combined length of the bases 100 and the spacing of the columns 200 can be flexibly adjusted according to the size requirements of different wind turbine truss models. This improves the versatility of the wind turbine truss device and breaks the limitation of traditional fixed tooling that is only compatible with a single product model. It eliminates the need to configure multiple sets of equipment for different trusses, reducing equipment investment and workshop floor space, improving tooling utilization, and adapting to the diverse production needs of the wind power industry.

[0044] In addition, the positioning part 310 of the positioning plate 300 can form a precise constraint on the truss on the support platform 210 through the lateral positioning function, replacing the traditional manual calibration method and reducing positioning errors; at the same time, the positioning plate 300 and the column 200 are detachably connected, and different specifications of positioning plates 300 can be replaced according to the lateral positioning requirements of the truss, further adapting to diverse truss structures and ensuring the stability of assembly accuracy.

[0045] Specifically, two adjacent bases 100 can be detachably connected by fasteners or by a snap-fit ​​structure. In this embodiment, no specific restrictions are placed on the detachable connection method of two adjacent bases 100.

[0046] For example, complementary snaps and slots (such as T-slots and T-blocks, mortise and tenon structures, etc.) are designed at the mating end of the base 100, which, together with positioning pins or locking bolts, enable quick engagement and fixation. After locking, the connection stability can be guaranteed and the assembly and disassembly efficiency can be improved.

[0047] Specifically, the base 100 can be configured as a rectangular frame structure, a square frame structure, etc. In this embodiment, the shape of the base 100 is not specifically limited.

[0048] For example, such as Figure 7 and Figure 9 As shown, the base 100 can be set as a semi-rectangular frame structure. By connecting two bases 100, a complete rectangular frame structure can be formed.

[0049] Specifically, multiple columns 200 can be spaced apart along the length of the base 100. The columns 200 and the base 100 can be connected by bolts or by a snap-fit ​​structure. In this embodiment, no specific restrictions are placed on the connection method between the columns 200 and the base 100.

[0050] In one embodiment, such as Figures 2 to 6As shown, the positioning plate 300 includes a connecting portion 320, which is connected to the positioning portion 310. The connecting portion 320 can be disposed below the positioning portion 310, and a plurality of connecting holes 321 are provided on the connecting portion 320. Correspondingly, the side wall of the column 200 is provided with a mounting portion 220, which is provided with a plurality of mounting holes 221, and the mounting holes 221 are correspondingly arranged with the connecting holes 321. When the positioning plate 300 is installed on the column 200, the connecting portion 320 on the positioning plate 300 is fitted with the mounting portion 220 on the column 200, and the connecting portion 320 and the mounting portion 220 are detachably connected by fasteners passing through the connecting holes 321 and the mounting holes 221.

[0051] The connecting part 320 and the mounting part 220 are connected by fasteners and detachable fitting with the connecting hole 321 and the mounting hole 221, supporting the quick disassembly and replacement of the positioning plate 300. When the wind turbine truss model changes or the lateral positioning requirements (such as positioning height and positioning hole 311 position) are adjusted, there is no need to modify the column 200 body. Only the positioning plate 300 of the corresponding specification needs to be replaced to adapt to the lateral constraint requirements of different trusses. This avoids the high cost problem of having to replace the entire column 200 for traditional welding or fixed connections, and further enhances the versatility of the device.

[0052] The multiple connecting holes 321 of the connecting part 320 are precisely matched with the corresponding mounting holes 221 of the mounting part 220. After being locked by fasteners, they can form a rigid connection, which prevents the positioning plate 300 from shifting or loosening during the truss support process. At the same time, the design of multiple connecting holes 321 can distribute the force, reduce the load of a single connection point, ensure the lateral positioning of the truss by the positioning part 310 is continuously stable, reduce the assembly error caused by loose connection, and improve the accuracy and consistency of wind power truss pre-assembly.

[0053] In practical applications, compared to non-removable structures such as welding, fastener connections do not require specialized welding equipment and technology. Operators can install, adjust, or replace the positioning plate 300 using only conventional tools, simplifying the assembly process and shortening production changeover time. In addition, if the positioning plate 300 is worn or damaged, it can be disassembled and replaced separately without scrapping the entire column 200, which greatly reduces equipment maintenance costs and resource waste.

[0054] Specifically, the fasteners can be bolt and nut assemblies, quick-release bolts, knob bolts, etc. In this embodiment, no specific restrictions are placed on the type of fastener.

[0055] In one embodiment, such as Figure 6 As shown, the positioning part 310 is provided with a plurality of positioning holes 311, which are used to connect with the truss.

[0056] The positioning hole 311 can be precisely aligned with the pre-set hole of the truss. Through the fasteners such as positioning pins and bolts, the truss and the positioning part 310 are rigidly constrained, avoiding the truss displacement or swaying that may occur when relying solely on lateral limiting in the traditional method.

[0057] The connection between the positioning hole 311 and the truss can form an additional support point, distributing the weight of the truss itself and the external forces during the assembly process (such as the thrust during adjustment) to the positioning part 310, avoiding deformation caused by excessive force on a single point of the support platform 210, and reducing the local stress caused by the concentration of lateral forces on the truss, thus reducing the risk of damage to the truss or support structure, especially suitable for the stable assembly requirements of large wind power trusses.

[0058] Specifically, the design of multiple positioning holes 311 can adapt to the hole layout of different trusses. When the truss model changes, resulting in different preset hole positions and quantities, it is not necessary to replace the entire positioning plate 300. It is only necessary to select the corresponding positioning hole 311 on the positioning part 310 to match the truss. If the truss does not have preset hole positions, connecting parts (such as clamping blocks) can also be temporarily installed through the positioning holes 311 to further expand the adaptability of the positioning part 310, form a synergy with the overall modular design of the device, and enhance the compatibility with multiple types of trusses.

[0059] In one embodiment, such as Figures 2 to 4 As shown, the column 200 also includes an adjustment plate 400, wherein the adjustment plate 400 is detachably mounted on the support platform 210, and the adjustment plate 400 is used to adjust the height of the bearing surface of the support platform 210.

[0060] The adjustable plate 400 can precisely adjust the bearing surface height of the support platform 210 by increasing or decreasing its quantity or changing its thickness, without modifying the column 200 itself, thus adapting to the differences in bottom support height of different wind turbine truss models. For example, when dealing with trusses with slightly lower heights, a thicker adjustable plate 400 can be added to raise the bearing surface; when dealing with trusses with higher heights, the adjustable plate 400 can be removed to lower the height, perfectly meeting the assembly requirements of various truss types and further enhancing the universal adaptability of the device.

[0061] Traditional fixed-height support platforms 210 require replacing the entire column 200 or custom-made shims to accommodate trusses of different heights, resulting in high costs and potential equipment downtime. In contrast, the adjustment plate 400 features a simple structure, low cost, and can be repeatedly disassembled and reused. It eliminates the need for multiple custom-made columns 200, significantly reducing equipment investment and resource waste for height adjustment, thus balancing economic efficiency and practicality.

[0062] In one embodiment, such as Figures 2 to 5As shown, the bottom of the column 200 is provided with a base plate 230, wherein the base plate 230 has multiple through holes 231. Correspondingly, the base 100 has multiple through holes, and the through holes are arranged corresponding to the through holes 231. The column 200 and the base 100 are detachably connected by fasteners passing through the through holes 231 and the corresponding through holes.

[0063] Multiple sets of through holes can be pre-set along the length of the base 100. When the size of the wind turbine truss changes and the spacing of the columns 200 needs to be adjusted, there is no need to modify the base 100 or the columns 200. Simply loosen the fasteners, move the base plate 230 of the column 200 along the base 100 to the corresponding through hole position, and then re-lock it. This breaks the limitations of traditional fixed installation and can quickly adapt to the layout requirements of the columns 200 of different truss models, further improving the device's compatibility with multi-variety production.

[0064] Compared to fixed connection methods such as welding, fastener connection does not require professional welding equipment. The installation and disassembly of column 200 can be completed with just conventional tools, which simplifies the assembly process and shortens the production changeover time. If column 200 or base 100 is partially damaged, the corresponding part can be removed and replaced separately without scrapping the entire structure, which greatly reduces equipment maintenance costs and resource waste, and extends the overall service life of the device.

[0065] The base plate 230 increases the contact area between the column 200 and the base 100, which can more evenly transfer the truss weight and lateral force borne by the column 200 to the base 100, avoiding deformation of the base 100 caused by local stress concentration. At the same time, the precise matching of multiple through holes 231 with the through holes can form multi-point fixation after being locked by multiple sets of fasteners, which restricts the displacement of the column 200 in the horizontal and vertical directions, prevents the column 200 from tilting or swaying during truss assembly or adjustment, and ensures stable support of large wind power trusses.

[0066] In one embodiment, such as Figure 3 As shown, the wind power truss device also includes a clamping member 500, wherein the base plate 230 and the base 100 are clamped by the clamping member 500 to realize the detachable connection between the column 200 and the base 100.

[0067] The clamping component 500 is fixed by directly clamping the base plate 230 to the base 100, eliminating the need for aligning holes with fasteners and repeated tightening operations. This allows for quick clamping or loosening of the column 200, making it particularly suitable for scenarios involving switching between production of multiple truss models. Compared to traditional bolt connections, this significantly reduces the time required for adjusting or replacing the column 200, minimizes production line downtime, and improves the overall assembly pace.

[0068] Fastener connections require high alignment accuracy between the through hole 231 and the through hole, and hole deviations can easily lead to assembly difficulties. However, the clamping component 500 clamps through surface contact, without strictly relying on hole alignment. Even if there are slight errors in the hole positions of the base plate 230 or the base 100, it can still be stably clamped and fixed, which lowers the accuracy threshold for part processing and assembly and reduces assembly rework caused by hole deviations.

[0069] Specifically, the clamping component 500 consists of a clamping block with a screw and an adjusting nut. One side of the clamping block is attached to the upper surface of the base plate 230. The screw passes through the pre-set elongated hole of the base 100. Tightening the nut will press and fix the base plate 230 and the base 100 together through the clamping block. Tightening it in the opposite direction will disassemble it. The clamping force can be controlled by the torque of the nut, which is suitable for trusses with heavy loads.

[0070] In one embodiment, such as Figure 7 and Figure 8 As shown, the wind power truss device also includes a connecting plate 600, wherein the ends of two adjacent bases 100 are connected by the connecting plate 600 to achieve a detachable connection.

[0071] The connecting plate 600 can splice multiple bases 100 into a whole of any length, eliminating the need to customize bases 100 of specific lengths for wind turbine trusses of different spans. For example, when assembling a small truss, 2-3 bases 100 can be spliced ​​together, and when assembling a large truss, the number of bases 100 can be increased. This breaks the limitations of traditional fixed-length bases 100 and greatly improves the device's adaptability to trusses of different sizes.

[0072] The connecting plate 600 forms a surface contact connection by covering the mating ends of the adjacent base 100. Compared with the line contact of the base 100 directly mating, it can transmit the weight and lateral force of the truss more evenly and avoid deformation or loosening at the mating point due to stress concentration. At the same time, multiple sets of fasteners (such as bolts) fix the connecting plate 600 and the base 100, which can further improve the overall rigidity and ensure the support stability during the assembly of large trusses.

[0073] The base 100 can be disassembled into independent units, eliminating the need to consider excessive length restrictions during transportation and saving transportation space and costs. It can also be stacked for storage, reducing workshop footprint. If a section of the base 100 is damaged, only the corresponding connecting plate 600 needs to be removed and the single section of the base 100 replaced, without scrapping the entire assembly structure, thus reducing maintenance costs and resource waste.

[0074] In one embodiment, such as Figure 1 , Figure 10 and Figure 11As shown, the base 100 is also provided with a plurality of crossbeams 700, wherein the plurality of crossbeams 700 are spaced apart along the length direction of the base 100. The crossbeams 700 are movable along the length direction of the base 100 and are fixed in the desired position by locking members, and each crossbeam 700 is detachably provided with a column 200.

[0075] The crossbeam 700 can move along the length of the base 100 and be fixed by locking devices. The spacing between adjacent crossbeams 700 can be freely adjusted according to the support point positions of different wind turbine truss models, thereby changing the installation layout of the column 200. Without modifying the base 100 or replacing the crossbeam 700, it can quickly adapt to differences in truss span and support point positions. Compared to a fixed crossbeam 700 design, this significantly improves the accuracy and flexibility of the column 200 layout.

[0076] Each crossbeam 700 can be detached and fitted with a column 200. Combined with the adjustable movement of the crossbeam 700, the number and position of the crossbeams 700 can be increased or decreased to accommodate various wind turbine trusses, ranging from small to large and from simple to complex. This eliminates the need for custom-designed crossbeam 700 components for different trusses, reducing investment in specialized tooling and increasing the reusability of the crossbeams 700 and columns 200, thus meeting the cost control requirements of the wind power industry's multi-variety production.

[0077] In one embodiment, such as Figure 10 and Figure 11 As shown, the base 100 is provided with a guide groove 110, which is arranged along the extension direction of the base 100. The end of the crossbeam 700 is provided with a pulley 710, which is movably arranged in the guide groove 110.

[0078] When the pulley 710 rolls within the guide groove 110, it converts the sliding friction between the crossbeam 700 and the base 100 into rolling friction, significantly reducing movement resistance. Operators can easily push the crossbeam 700 along the length of the base 100 to adjust its position without expending considerable effort. Even when the crossbeam 700 is supporting the column 200, it can still move smoothly, significantly reducing operator workload and shortening adjustment time.

[0079] The guide groove 110 forms a lateral constraint on the pulley 710 through the groove wall, which can strictly limit the movement trajectory of the crossbeam 700, prevent the crossbeam 700 from shifting left or right or tilting during the adjustment process, ensure that the crossbeam 700 always moves accurately along the length direction of the base 100, thereby ensuring the consistency of the subsequent installation position of the column 200, reducing the truss positioning error caused by the offset of the crossbeam 700, and improving the overall assembly accuracy.

[0080] In one embodiment, such as Figures 1 to 7As shown, the base 100 is provided with at least one hoisting point 120. The side wall of the column 200 is provided with at least one lug 240, wherein the lug 240 is provided with a hoisting hole 241.

[0081] The lifting points 120 of the base 100 can be used with cranes, forklifts, and other equipment to achieve the overall lifting of single or multiple sections of the spliced ​​base 100 without relying on manual handling. This is especially suitable for the relocation of large base 100s in workshops or for warehouse transfer. The lugs 240 and lifting holes 241 of the column 200 can be directly hooked for lifting, facilitating the separate transportation of the column 200 to the installation location of the base 100, or its rapid disassembly and relocation during maintenance. The combination of these two features allows the components of the device to be disassembled, transported, and then reassembled on-site, solving the problems of difficult transportation and large footprint of integral tooling.

[0082] Specifically, when assembling the truss device, differential columns 200 can be set at both ends of the base 100 along its length to attach the differential and prevent operators from falling.
