Description

Technical Field

[0001] This application relates to the field of wind power generation technology, and in particular to a wind turbine split-type rack positioning device. Background Technology

[0002] As the wind power industry develops towards large megawatt-level, split-type racks are widely used due to their advantages such as convenient transportation and adaptability to large-size assembly. Their assembly accuracy directly affects the stability of wind turbine operation, and the requirements for the accuracy of positioning and assembly equipment are stringent.

[0003] In existing technologies, on-site assembly mainly relies on gantry cranes for hoisting, jacks, and pad blocks, with operators assisting in the process. Due to the relatively large size of the frame, it is difficult to control the alignment accuracy between the various components during assembly, resulting in low assembly efficiency. Utility Model Content

[0004] The purpose of this application is to provide a wind turbine split-type rack positioning device, which can ensure the overall structural accuracy of the rack after assembly, thereby ensuring the operational stability of the wind turbine.

[0005] This utility model provides a positioning device for a split-type wind turbine rack, comprising at least two positioning mechanisms spaced apart, wherein the positioning mechanism includes: Base; A positioning seat is fixed on the base. The positioning seat is provided with a bearing surface and a limiting surface. The bearing surface and the limiting surface are adjacent to each other and are set at an angle. At least one limiting hole is opened on the limiting surface. When the head plate of the frame is installed on the positioning seat, the bearing surface is used to support the head plate, and the limiting surface abuts against the side wall of the head plate and is connected to the head plate through the limiting hole by a connector.

[0006] Beneficial effects: This wind turbine split-type frame positioning device, during the assembly of the split-type frame, involves installing at least two positioning mechanisms at preset intervals along the length of the positioning mechanism. First, the head plate on one side of the frame is placed on the positioning seat of one of the positioning mechanisms. The bearing surface of the positioning seat provides stable support for the head plate, while ensuring tight contact between the side wall of the head plate and the limiting surface of the positioning seat. Then, a connector is used to pass through the limiting hole and securely connect to the head plate, completing the fixation of that side of the head plate. Subsequently, using this side of the head plate as a reference, the same installation method is used to fix the head plate on the other side of the frame to another positioning mechanism. The two positioning mechanisms achieve precise alignment of the head plates on both sides of the frame. Finally, the middle connecting beam of the frame is connected to the two sides of the frame, completing the assembly of the entire frame.

[0007] The precise positioning structure is formed by the bearing surface and limiting surface of the positioning seat. The bearing surface provides stable support for the head plate of the frame, avoiding uneven force and support point misalignment problems that occur when operators use pads for support. The limiting surface abuts tightly against the side wall of the head plate, which can restrict the displacement of the head plate from the side. With the connecting piece passing through the limiting hole and fixed to the head plate, the movement of the head plate along the length direction of the positioning mechanism is restricted, thereby ensuring that the head plate is accurately positioned and firmly fixed on the frame. Compared with the positioning method of operators relying on repeated calibration with jacks and temporary support with pads, this device can precisely control the relative position of each component of the frame, effectively reducing docking deviations, ensuring the overall structural accuracy of the frame after assembly, and thus ensuring the stability of the fan operation.

[0008] Furthermore, during the installation of the mechanical headplate, the headplate eliminates the need for repeated alignment adjustments by operators. It can directly align with the bearing and limiting surfaces of the positioning seat to quickly achieve initial positioning, followed by fastening with connectors. This significantly reduces the time spent waiting for the gantry crane during hoisting and the time required for repeated adjustments and calibrations by operators. Simultaneously, at least two spaced positioning mechanisms form multi-point collaborative positioning, enabling simultaneous positioning and fixing of different parts of the frame. This avoids secondary adjustments required for single-point positioning, further shortening the assembly cycle and reducing the labor intensity and time costs for operators.

[0009] In one optional embodiment, a positioning hole is further provided on the limiting surface of the positioning seat, and a positioning pin is detachably provided in the positioning hole; When the head plate of the frame is installed on the positioning seat, the positioning pin is embedded in the corresponding connection hole of the head plate.

[0010] Beneficial effects: During assembly, the locating pin can be directly used as a guide reference component. Operators only need to align the connecting hole of the head plate with the locating pin and insert it to quickly complete the initial alignment of the head plate and the locating seat, without the need for repeated measurement and adjustment of the head plate position. Especially for large-sized and heavy wind turbine frame head plates, it can effectively reduce the time and difficulty of calibration for operators, avoid rework due to misalignment caused by visual errors or improper operation, and greatly improve assembly efficiency.

[0011] In one alternative embodiment, the top edge of the limiting surface of the positioning seat is chamfered.

[0012] Beneficial effects: The inclined transition surface formed by the chamfer can serve as an assembly guide structure. When the lifting head plate aligns with the positioning seat, even if there is a slight deviation in the initial position of the head plate, the chamfer can guide the head plate to slide along the inclined surface to the correct assembly position, avoiding alignment difficulties caused by the right angle of the edge jamming the head plate. This is especially suitable for the lifting and assembly of large-sized, heavy-duty head plates, reducing the number of adjustments and improving assembly efficiency.

[0013] In one optional embodiment, the positioning mechanism further includes a plurality of adjustment components, which are respectively located on opposite sides of the positioning seat along its length. When the head plate of the frame is placed on the positioning seat, the adjustment assembly is used to drive the head plate to move along the length direction of the positioning seat.

[0014] Beneficial effects: When the head plate is hoisted and placed on the bearing surface, if the head plate position is deviated and needs to be adjusted, pressure is applied to both sides of the head plate by adjusting the components, driving the head plate to move along the length of the positioning seat, and the adjustment can be made directly in place without repeated hoisting or moving of the head plate, which greatly reduces the adjustment time and operation difficulty. It is especially suitable for assembly scenarios of large-size, heavy-load head plates, and effectively improves the overall assembly efficiency.

[0015] In one alternative implementation, when the headplate of the frame is mounted on the positioning seat, the plurality of adjustment components clamp the headplate from opposite sides.

[0016] Beneficial effects: The double-sided clamping of the adjustment component can form a continuous and balanced bidirectional constraint force, which firmly locks the head plate position laterally, effectively preventing it from shifting along the length of the positioning seat or laterally, providing a stable and reliable benchmark for the precise docking of various components of the frame, and further ensuring the overall assembly accuracy.

[0017] In one alternative embodiment, the positioning mechanism further includes a plurality of leveling components, which are spaced apart around the periphery of the base and are used to adjust the levelness of the base.

[0018] Beneficial effects: The installation ground at wind power sites is often uneven. The leveling component can flexibly adapt to different ground conditions and achieve precise leveling through multi-point interval adjustment. There is no need for complicated pre-treatment of the installation ground, which broadens the applicable scenarios of the positioning device and reduces the environmental requirements and pre-preparation costs for on-site installation.

[0019] In one optional embodiment, the positioning seat includes a connecting part and a plurality of positioning parts, each of the positioning parts being provided with the bearing surface and the limiting surface; Multiple positioning parts are connected by the connecting part and are spaced apart along the length direction of the positioning seat.

[0020] Beneficial effects: The spaced positioning parts, together with the connecting parts, form a frame structure, which ensures overall rigidity while reducing material usage, achieving a lightweight design for easy transportation. Simultaneously, the dispersed positioning parts reduce the precision requirements for individual components, resulting in lower processing difficulty and a lower scrap rate compared to a single, large-sized positioning surface, effectively controlling manufacturing costs. Furthermore, if a single positioning part is worn or damaged, it can be replaced individually without scrapping the entire positioning base, reducing subsequent maintenance costs.

[0021] In one alternative embodiment, the base has multiple mounting holes at its bottom.

[0022] Beneficial effects: By using mounting holes and fasteners such as bolts and expansion bolts, the base can be firmly fixed to the ground, tooling platform, or other installation foundations, preventing the positioning mechanism from shifting or shaking due to force or vibration during head plate assembly and adjustment. This provides a stable foundation support for subsequent head plate positioning and frame assembly, ensuring overall positioning accuracy from the installation perspective.

[0023] In one optional embodiment, the wind turbine split-type frame positioning device further includes at least one connecting rod, and two adjacent positioning mechanisms are connected by the connecting rod.

[0024] Beneficial effects: The connecting rods firmly connect adjacent positioning mechanisms, forming a unified rigid frame from multiple dispersed positioning mechanisms. This prevents individual positioning mechanisms from shifting or tilting due to headplate pressure, assembly forces, or vibration. Especially in the complex environment of wind power sites, it can effectively resist external interference, ensuring that the relative positions of each positioning mechanism remain unchanged, and providing a stable structural foundation for the precise alignment of the headplates on both sides.

[0025] In one alternative embodiment, the operating end of the positioning pin is provided with an installation handle.

[0026] Beneficial effects: The handle provides a clear point of force application for inserting and removing the locating pin, eliminating the need for auxiliary tools such as pliers. Operators can directly hold the handle to quickly install or remove the locating pin. Especially in scenarios where locating pins need to be frequently adjusted during the assembly process, it can significantly reduce the time spent on tool retrieval and operation adaptation, thereby improving overall assembly efficiency.

[0030] In related technologies, on-site assembly mainly relies on gantry cranes, jacks, and spacers for operators to assemble the machine. Due to the relatively large size of the frame, it is difficult to control the alignment accuracy between the various components during assembly, resulting in low assembly efficiency.

[0031] In the early stages of the research and development of this application, in order to solve the problem of low accuracy in manual assembly of wind turbine split frames, a basic positioning device was designed to replace the traditional rough positioning method of pads and jacks, which effectively improved the installation accuracy of individual components of the frame and verified the feasibility of mechanical positioning.

[0032] However, the preliminary design has limitations when dealing with large-size racks. Due to the large size of the rack and the high requirements for component coordination and positioning, relying solely on the basic positioning device requires repeated hoisting and adjustment of the overall position of the rack. It is necessary to ensure that the components fit with the positioning structure and align the holes, which not only prolongs the positioning time but also easily causes component damage or reference offset, exposing the inadequacy of the overall coordination and positioning capability.

[0033] Based on this, the inventors of this application have redesigned the positioning device for a split-type wind turbine frame. During the assembly of the split-type frame, at least two positioning mechanisms are installed at a preset interval along the length of the positioning mechanism. First, the head plate on one side of the frame is placed on the positioning seat of one of the positioning mechanisms. The bearing surface of the positioning seat provides stable support for the head plate, while ensuring tight contact between the side wall of the head plate and the limiting surface of the positioning seat. Then, a connector is used to pass through the limiting hole and securely connect to the head plate, completing the fixing of that side of the head plate. Subsequently, using this side of the head plate as a reference, the head plate on the other side of the frame is fixed to another positioning mechanism using the same installation method. The two positioning mechanisms achieve precise alignment of the head plates on both sides of the frame. Finally, the middle connecting beam of the frame is connected to both sides of the frame, completing the assembly of the entire frame.

[0034] The precise positioning structure is formed by the bearing surface and limiting surface of the positioning seat. The bearing surface provides stable support for the head plate of the frame, avoiding uneven force and support point misalignment problems that occur when operators use pads for support. The limiting surface abuts tightly against the side wall of the head plate, which can restrict the displacement of the head plate from the side. With the connecting piece passing through the limiting hole and fixed to the head plate, the movement of the head plate along the length direction of the positioning mechanism is restricted, thereby ensuring that the head plate is accurately positioned and firmly fixed on the frame. Compared with the positioning method of operators relying on repeated calibration with jacks and temporary support with pads, this device can precisely control the relative position of each component of the frame, effectively reducing docking deviations, ensuring the overall structural accuracy of the frame after assembly, and thus ensuring the stability of the fan operation.

[0035] Furthermore, during the installation of the mechanical headplate, the headplate eliminates the need for repeated alignment adjustments by operators. It can directly align with the bearing and limiting surfaces of the positioning seat to quickly achieve initial positioning, followed by fastening with connectors. This significantly reduces the time spent waiting for the gantry crane during hoisting and the time required for repeated adjustments and calibrations by operators. Simultaneously, at least two spaced positioning mechanisms form multi-point collaborative positioning, enabling simultaneous positioning and fixing of different parts of the frame. This avoids secondary adjustments required for single-point positioning, further shortening the assembly cycle and reducing the labor intensity and time costs for operators.

[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 with Figures 1 to 5 The following describes embodiments of the present invention.

[0038] According to embodiments of the present invention, such as Figures 1 to 5As shown, a wind turbine split-type rack positioning device is provided, including at least two positioning mechanisms 1000, wherein the at least two positioning mechanisms 1000 are arranged at intervals along the length direction of the positioning mechanism 1000.

[0039] Specifically, such as Figures 1 to 4 As shown, the positioning mechanism 1000 includes a base 100 and a positioning seat 200. The positioning seat 200 is fixedly mounted on the base 100 and has a bearing surface 210 and a limiting surface 220. The bearing surface 210 and the limiting surface 220 are arranged adjacent to each other and at an angle to each other. At least one limiting hole 221 is provided on the limiting surface 220.

[0040] Specifically, such as Figures 1 to 4 As shown, when the head plate 3000 of the frame is installed on the positioning seat 200, the bearing surface is used to support the bottom of the head plate 3000, the limiting surface 220 abuts against the side wall of the head plate 3000, and is connected to the head plate 3000 through the limiting hole 221 via the connector 300.

[0041] This wind turbine split-type rack positioning device, when assembling the split-type rack, involves installing at least two positioning mechanisms 1000 at a preset interval along the length of the positioning mechanism 1000; first, the head plate 3000 on one side of the rack is placed on the positioning seat 200 of one of the positioning mechanisms 1000, and the head plate 3000 is stably supported by the bearing surface 210 of the positioning seat 200, while ensuring that the side wall of the head plate 3000 is in close contact with the limiting surface 220 of the positioning seat 200, and then the connector 300 is fastened to the head plate 3000 through the limiting hole 221 to complete the fixing of the head plate 3000 on that side. Then, using the head plate 3000 on that side as a reference, the head plate 3000 on the other side of the frame is fixed to another positioning mechanism 1000 using the same installation method. The two positioning mechanisms 1000 are used to achieve precise alignment of the head plates 3000 on both sides of the frame. Finally, the middle connecting beam of the frame is connected to the two sides of the frame to complete the assembly of the entire frame.

[0042] The positioning seat 200 forms a precise positioning structure with its bearing surface 210 and limiting surface 220. The bearing surface 210 provides stable support for the head plate 3000, avoiding uneven force distribution and support point misalignment issues that occur when operators use pads for support. The limiting surface 220 abuts tightly against the side wall of the head plate 3000, restricting its displacement from the side. Combined with the connector 300 passing through the limiting hole 221 and fixed to the head plate 3000, this restricts the head plate 3000 from moving along the length of the positioning mechanism 1000, ensuring accurate and secure positioning of the head plate 3000 on the frame. Compared to operators relying on repeated calibration with jacks and temporary support with pads, this device precisely controls the relative positions of the frame components, effectively reducing docking deviations and ensuring the overall structural accuracy of the assembled frame, thereby guaranteeing the stability of the fan operation.

[0043] Furthermore, during the installation of the mechanical headplate 3000, the headplate 3000 does not require repeated adjustments by operators. It can directly align with the bearing surface 210 and limiting surface 220 of the positioning seat 200 to quickly complete the initial positioning, and then be secured by the connector 300. This significantly reduces the time spent waiting for the gantry crane to lift and the time spent by operators repeatedly adjusting and calibrating. At the same time, at least two spaced positioning mechanisms 1000 form multi-point collaborative positioning, which can simultaneously complete the positioning and fixing of different parts of the frame, avoiding secondary adjustments caused by single-point positioning, further shortening the assembly cycle, and reducing the labor intensity and time cost for operators.

[0044] Specifically, the angle between the bearing surface 210 and the limiting surface 220 is related to the angle between the bottom surface and the side wall surface of the head plate 3000. For example, if the bottom surface and the side wall surface of the head plate 3000 are perpendicular to each other, then the bearing surface 210 and the limiting surface 220 are set perpendicularly. In this embodiment, the angle between the bearing surface 210 and the limiting surface 220 is not specifically limited.

[0045] Specifically, the connector 300 can be selected from bolt assemblies, locking pins, safety pins, etc. In this embodiment, the type of connector 300 is not specifically limited.

[0046] For example, the connector 300 is a bolt assembly. The bolt passes through the limiting hole 221 of the positioning seat 200 and is fastened to the threaded hole (or with a nut) of the head plate 3000. By adjusting the preload, the head plate 3000 can be tightly fitted to the limiting surface 220. It is also easy to disassemble and is suitable for scenarios that require repeated assembly and disassembly or fine adjustment.

[0047] In one embodiment, such as Figures 2 to 4As shown, the positioning seat 200 is also provided with a positioning hole 222, wherein the positioning hole 222 is located on the limiting surface 220, and a positioning pin 400 is detachably provided in the positioning hole 222. When the head plate 3000 of the frame is installed on the positioning seat 200, the positioning pin 400 passes through the positioning hole 222 and is embedded in the corresponding connecting hole of the head plate 3000.

[0048] During assembly, the locating pin 400 can be directly used as a guide reference component. The operator only needs to align the connecting hole of the head plate 3000 with the locating pin 400 and insert it to quickly complete the initial alignment of the head plate 3000 and the locating seat 200, without the need for repeated measurement and adjustment of the head plate 3000 position. Especially for large-sized and heavy wind turbine frame head plates 3000, it can effectively reduce the time and difficulty of calibration for operators, avoid rework due to misalignment caused by visual errors or improper operation, and greatly improve assembly efficiency.

[0049] The positioning pin 400 and the positioning hole 222 and the head plate 3000 connection hole adopt a high-precision fit (such as transition fit or small clearance fit), which can strictly limit the slight displacement of the head plate 3000 in the plane of the positioning seat 200 from the spatial position, and avoid the overall docking accuracy of the frame being affected by the positioning deviation.

[0050] Before the connector 300 is fully tightened, the head plate 3000, supported only by the bearing surface 210 and abutted by the limiting surface 220, may experience slight displacement due to hoisting swaying or lateral forces. However, once the positioning pin 400 is inserted, it forms a rigid positioning fulcrum between the head plate 3000 and the positioning seat 200, firmly locking the head plate 3000 in position and preventing displacement during tightening. After the connector 300 is fixed, the positioning pin 400 and the connector 300 form a double fixation, further enhancing the connection stability between the head plate 3000 and the positioning seat 200, preventing loosening due to vibration during subsequent frame assembly or fan operation.

[0051] In one embodiment, such as Figure 4 As shown, the positioning seat 200 has a chamfer 223 at the top edge of the limiting surface 220.

[0052] The inclined transition surface formed by chamfer 223 can serve as an assembly guide structure. When the lifting head plate 3000 aligns with the positioning seat 200, even if there is a slight deviation in the initial position of the head plate 3000, chamfer 223 can guide the head plate 3000 to slide along the inclined surface to the correct assembly position, avoiding alignment difficulties caused by the right angle of the edge jamming the head plate 3000. This is especially suitable for the lifting and assembly of large-size, heavy-duty head plates 3000, reducing the number of adjustments and improving assembly efficiency.

[0053] Furthermore, during the hoisting process, the headplate 3000 is prone to collision with the top edge of the limiting surface 220 of the positioning seat 200. Collisions with right-angled edges can easily cause scratches and deformation to the side wall of the headplate 3000 or the edge of the positioning seat 200, affecting the accuracy and service life of the components. However, the chamfer 223 can disperse the collision force, transforming sharp point / line contact into surface contact, reducing local stress concentration, effectively avoiding damage to components caused by collisions, and ensuring the structural integrity of the positioning device and the frame headplate 3000.

[0054] Specifically, the chamfer 223 can be either a rounded chamfer 223 or a beveled chamfer 223. In this embodiment, the type of chamfer 223 is not specifically limited.

[0055] In one embodiment, such as Figure 2 and Figure 3 As shown, the positioning mechanism 1000 also includes multiple adjustment components 500, wherein the multiple adjustment components 500 are respectively arranged on opposite sides of the positioning seat 200 along the length direction of the positioning seat 200. When the head plate 3000 of the frame is placed on the positioning seat 200, the adjustment components 500 can drive the head plate 3000 to move along the length direction of the positioning seat 200.

[0056] When the head plate 3000 is hoisted and placed on the bearing surface 210, if the position of the head plate 3000 needs to be adjusted due to deviation, the adjustment component 500 applies pressure to both sides of the head plate 3000, driving the head plate 3000 to move along the length direction of the positioning seat 200, and directly making in-situ adjustments without the need for repeated hoisting or moving of the head plate 3000, greatly reducing adjustment time and operation difficulty. It is especially suitable for assembly scenarios of large-size, heavy-load head plates 3000, effectively improving overall assembly efficiency.

[0057] Furthermore, the adjustment assembly 500 applies force from opposite sides along the length of the positioning seat 200, ensuring a more balanced force on the head plate 3000 and preventing tilting, displacement, or frictional damage to the head plate 3000 caused by unilateral force application. Compared to rough adjustment methods such as manual prying, this adjustment method better protects the structural integrity of the head plate 3000 and the positioning device, reducing component wear during assembly.

[0058] Specifically, the adjustment component 500 may be a screw drive mechanism, a hydraulic / pneumatic drive mechanism, etc. In this embodiment, the type of adjustment component 500 is not specifically limited.

[0059] Specifically, the adjustment component 500 can be disposed on the base 100 or on the positioning seat 200. In this embodiment, the installation position of the adjustment component 500 is not specifically limited.

[0060] In one embodiment, such as Figures 2 to 4As shown, when the head plate 3000 of the frame is installed on the positioning seat 200, the adjustment components 500 located on both sides of the head plate 3000 clamp the two sides of the head plate 3000 respectively.

[0061] In scenarios such as the connection of intermediate beams in the frame, subsequent component assembly, or external force contact, while basic positioning and fixation can be achieved solely by the positioning pin 400 and connector 300, slight displacement may occur due to vibration, assembly forces, etc. The double-sided clamping of the adjustment component 500 can form a continuous and balanced bidirectional constraint force, firmly locking the head plate 3000 in position laterally, effectively preventing its displacement along the length or side of the positioning seat 200, providing a stable and reliable benchmark for the precise docking of various components of the frame, and further ensuring the overall assembly accuracy.

[0062] In one embodiment, such as Figures 2 to 4 As shown, the positioning mechanism 1000 also includes a plurality of leveling components 600, which are spaced apart around the periphery of the base 100. The leveling components 600 are used to adjust the levelness of the base 100.

[0063] The installation ground at wind power sites is often uneven. The leveling component 600 can flexibly adapt to different ground conditions and achieve precise leveling through multi-point interval adjustment (set around the base 100). There is no need for complicated pre-treatment of the installation ground, which broadens the applicable scenarios of the positioning device and reduces the environmental requirements and pre-preparation costs for on-site installation.

[0064] The leveling component 600 can eliminate unevenness errors of the installation surface (such as the ground at the construction site) by adjusting, so that the base 100 is in a horizontal state. This ensures that the bearing surface 210 of the positioning seat 200 is horizontal and the limiting surface 220 is vertical, providing a reliable benchmark for the accurate positioning of the head plate 3000. It also avoids tilting or offset of the head plate 3000 due to the tilt of the base 100, thereby reducing the cumulative error of the overall frame assembly from the source.

[0065] If the base 100 is tilted, the weight of the head plate 3000 and the frame components will generate a lateral component force, causing uneven stress on the positioning seat 200, connecting parts 300, etc., which may lead to component deformation or loosening in the long term. After the leveling component 600 makes the base 100 level, it can evenly distribute the weight of the head plate 3000 to the base 100 and the leveling component 600, ensuring balanced force on each component, reducing stress concentration, and improving the overall structural stability and service life of the positioning mechanism 1000.

[0066] In one embodiment, such as Figures 2 to 4As shown, the positioning base 200 includes a connecting portion 230 and a plurality of positioning portions 240, wherein each positioning portion 240 is provided with a bearing surface 210 and a limiting surface 220. Along the length direction of the positioning base 200, the plurality of positioning portions 240 are spaced apart, and the plurality of positioning portions 240 are connected by the connecting portion 230.

[0067] The spaced positioning parts 240, together with the connecting parts 230, form a frame structure, which ensures overall rigidity while reducing material usage, achieving a lightweight design for easy transportation. Simultaneously, the dispersed positioning parts 240 reduce the machining precision requirements of individual components, resulting in lower machining difficulty and scrap rates compared to a single, large-sized positioning surface, effectively controlling manufacturing costs. Furthermore, if a single positioning part 240 is worn or damaged, it can be replaced individually without scrapping the entire positioning seat 200, reducing subsequent maintenance costs.

[0068] Multiple positioning parts 240 are spaced apart along the length direction. Each positioning part 240 supports and limits the head plate 3000 through a bearing surface 210 and a limiting surface 220. Compared with a single integral positioning surface, it can more comprehensively cover the support and limiting requirements of the head plate 3000, avoid the situation where the head plate 3000 is partially suspended or unevenly stressed due to its large length, and further prevent the head plate 3000 from warping or shifting during assembly, ensuring the stability and accuracy of positioning.

[0069] In one embodiment, such as Figure 2 As shown, the base 100 has multiple mounting holes 110 at its bottom.

[0070] By using mounting holes 110 and fasteners such as bolts and expansion bolts, the base 100 can be firmly fixed to the ground, tooling platform, or other installation bases. This prevents the positioning mechanism 1000 from shifting or shaking due to force or vibration during the assembly and adjustment of the head plate 3000, providing stable foundation support for the subsequent positioning of the head plate 3000 and the assembly of the frame, thus ensuring overall positioning accuracy from the installation perspective.

[0071] Multiple mounting holes 110 correspond to multiple fixing points, which can evenly transfer the gravity and assembly force of the positioning mechanism 1000 and frame components to the mounting base, avoid local stress concentration caused by single-point fixing, reduce the risk of deformation of the base 100 or damage to the mounting base, extend the service life of the positioning device and the mounting base, and ensure the structural stability for long-term use.

[0072] In one embodiment, such as Figure 1 As shown, the wind turbine split-type frame positioning device also includes at least one connecting rod 2000, wherein two adjacent positioning mechanisms 1000 are connected by the connecting rod 2000.

[0073] The connecting rod 2000 firmly connects adjacent positioning mechanisms 1000, forming a unified rigid frame from multiple dispersed positioning mechanisms 1000. This prevents individual positioning mechanisms 1000 from shifting or tilting due to pressure from the head plate 3000, assembly forces, or vibrations. Especially in the complex environment of wind power sites, it can effectively resist external interference, ensuring that the relative positions of each positioning mechanism 1000 remain unchanged, and providing a stable structural foundation for the precise alignment of the head plates 3000 on both sides.

[0074] By connecting the connecting rods 2000, the spacing and parallelism between adjacent positioning mechanisms 1000 are fixed, ensuring that the bearing surface 210 and the limiting surface 220 of the positioning seat 200 of each positioning mechanism 1000 are on the same reference plane. This avoids inconsistencies in the installation reference of the two head plates 3000 due to the offset of a single positioning mechanism 1000, thereby reducing the cumulative error of the frame docking from the source and ensuring the precise docking of the middle connecting beam and the two head plates 3000.

[0075] Specifically, such as Figure 1 As shown, connecting rods 2000 can be installed on both the front and rear sides of the positioning mechanism 1000, and multiple connecting rods 2000 can be used to ensure that two adjacent positioning mechanisms 1000 are firmly connected.

[0076] Specifically, the connecting rod 2000 and the positioning mechanism 1000 are detachably fastened with bolts. To further improve the positioning accuracy at the connection, a positioning stud can be added at the connection part 230 to form a dual guarantee structure of bolt fastening and stud positioning.

[0077] In one embodiment, such as Figure 5 As shown, the operating end of the positioning pin 400 is equipped with an installation handle 410.

[0078] The mounting handle 410 provides a clear point of force application for inserting and removing the locating pin 400. Without the need for auxiliary tools such as pliers, operators can directly hold the handle to quickly install or remove the locating pin 400. Especially in scenarios where the locating pin 400 needs to be frequently adjusted during the assembly process, it can significantly reduce the time spent on tool retrieval and operation adaptation, thereby improving overall assembly efficiency.

[0079] If the operating end of the positioning pin 400 does not have a handle 410, fingers may rub against the edge of the positioning seat 200 or the side wall of the head plate 3000 when inserting or removing the pin, or the positioning pin 400 may slip and cause damage. The handle 410 can increase the grip distance during operation and prevent fingers from directly contacting the assembly contact surface, which can protect the operator's hand safety and prevent accidental scratches to the parts caused by fingers touching the parts.
