As an important part of the entire wind turbine, the blade can only have a greater competitive advantage by changing the processing technology and improving the overall production efficiency of the blade while ensuring its quality. In order to ensure the smooth installation of the blades during installation in the wind farm, the root of the blade must be tested with the hub tooling before it is allowed to be shipped. The test installation of the blade hub test tooling has become an indispensable process in the current blade production process. Due to the heavy weight of the hub test tooling, the previous hub test installation work was carried out by crane + forklift, which not only has certain safety hazards, but also has low efficiency.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0043] like Figure 1-4 As shown, the present invention discloses a device for rapid test assembly of a wind turbine blade hub tooling, comprising a hub bracket 1, a movable bracket 2, a rotary beam 3, a lifting frame 4 and a base 5;

[0044] The wheel hub bracket 1 is connected to the mobile bracket 2, and the wheel hub bracket 1 is used to fix the wheel hub tooling;

[0045] The movable bracket 2 is connected to the rotary beam 3 and is used to adjust the position of the hub bracket 1 in the left and right directions;

[0046] The slewing beam 3 is hinged to the lifting frame 4 to adjust the angle between the hub bracket 1 and the up and down directions;

[0047] The lifting frame 4 is connected to the base 5, and the lifting frame 4 is used to adjust the position of the hub bracket 1 in the up and down direction;

[0048] The base 5 is used to support the entire device and to be able to move the hub tooling.

[0049] The movable bracket 2 is connected to the revolving beam 3 and is used to adjust the position of the hub bracket 1 in the left and right directions. The design of the revolving beam 3 and the lifting frame 4 provides fine angle and height adjustment capabilities, which helps to achieve high-quality assembly. The base 5 not only supports the entire device, but also can move the hub tooling, making the layout in the workshop more flexible. This device allows the user to accurately adjust the position of the hub left and right, up and down, and angle in three-dimensional space to ensure the best assembly position, avoids the use of a crane + forklift for trial installation, reduces the time required for hub trial installation, and improves the speed and accuracy of the assembly process. The stable base design ensures the safety of the equipment during operation, while reducing the risk of workers manually adjusting large components.

[0050] This arrangement integrates the hub bracket 1, the mobile bracket 2, the rotating crossbeam 3, the lifting frame 4 and the base 5 into one, forming a compact and efficient assembly platform. By fine-tuning the height, left and right position and angle of the hub tooling, while improving operational safety, the efficiency of the hub trial assembly process can be greatly improved, and the complex assembly steps are simplified, so that when docking with the root of the blade, it can be adjusted according to the offset situation and the root docking can be quickly completed. This not only eliminates the safety hazards caused by the crane and forklift, but also greatly improves the efficiency of the trial assembly, and can also solve the problem of a high bolt damage rate caused by the trial assembly process due to the inability to achieve precise adjustment of the original hub tooling.

[0051] Specifically, the wheel hub bracket 1 includes a fixed seat 101, four positioning rods 102 and four support rods 103. The fixed seat 101 is used to connect the mobile bracket 2. One end of the positioning rod 102 is connected to the fixed seat 101. The end of the positioning rod 102 away from the fixed seat 101 is provided with a claw 104. The claw 104 is used to limit the displacement of the wheel hub tooling along the front and rear directions. The four positioning rods 102 are evenly distributed along the circumference of the fixed seat 101. The two ends of the support rod 103 are respectively connected to two adjacent positioning rods 102, which are used to improve the structural rigidity of the wheel hub bracket 1.

[0052] The fixed seat 101 serves as the basic part of the wheel hub bracket 1. It ensures the stability of the entire bracket structure and provides a connection point for installation on the mobile bracket 2. The claws 104 on the four positioning rods 102 are used to limit the displacement of the hub tooling in the front and rear directions, ensuring the stable position of the hub during transportation and assembly and preventing displacement due to accidental collision or operational errors. The positioning rods 102 are evenly distributed along the circumference of the fixed seat 101, which not only makes the force distribution more uniform, but also helps to align the center of the hub tooling and improve the assembly accuracy. The support rods 103 connect adjacent positioning rods 102 to enhance the overall structural stiffness of the wheel hub bracket 1, thereby improving its load-bearing capacity and anti-deformation ability.

[0053] This setting improves the reliability and safety of assembly, helps to achieve precise alignment of the hub tooling, has high structural rigidity, reduces possible deformation under heavy load conditions, and ensures stability and durability for long-term use.

[0054] Specifically, the fixing seat 101 is a U-shaped structure, and the fixing seat 101 has through holes 1011 evenly distributed around the circumference for connecting the movable bracket 2 .

[0055] The U-shaped structure provides additional internal support, enhances the overall rigidity and stability of the fixing seat 101, helps to resist the influence of external forces, can more evenly disperse the pressure from the hub tooling and other components, avoid local stress concentration, and improve the durability of the structure. It can more evenly disperse the pressure from the hub tooling and other components, avoid local stress concentration, improve the durability of the structure, and enable the fixing seat 101 to adapt to different connection methods, such as bolts, pins, etc., increasing the flexibility and versatility of the device.

[0056] This setup has high stability and reliability, simplifies the manufacturing process, helps improve maintenance convenience, and reduces maintenance time and costs.

[0057] Specifically, the fixing seat 101 and the positioning rod 102 , and the positioning rod 102 and the supporting rod 103 are connected to form an integrated structure by welding.

[0058] The integrated structure of welded connections reduces the number of moving parts and the possibility of regular maintenance due to wear or loosening of connectors. The integrated design reduces the workload of on-site assembly and only requires simple positioning and fixing to complete the installation, which improves assembly efficiency, improves the device's ability to resist external impact and vibration, and reduces the risk of deformation.

[0059] Specifically, the claw 104 is a U-shaped groove, and the bottom of the claw 104 is detachably connected or fixedly connected to the positioning rod 102.

[0060] Since the clamping claw 104 is a U-shaped groove structure, it can adapt to hub tooling of different diameters within a certain range, increasing the versatility of the device. The design of the U-shaped groove can effectively limit the axial movement of the hub tooling, ensuring that it maintains a stable position during the assembly process and preventing the hub tooling from accidentally slipping off. The detachable connection between the clamping claw 104 and the positioning rod 102 makes installation and replacement more convenient and quick, improving work efficiency. The detachable connection allows the position or angle of the clamping claw 104 to be adjusted according to actual needs to adapt to different assembly requirements or specific hub models. The clamping claw 104 of different shapes or materials can also be customized according to specific application requirements, such as using wear-resistant and corrosion-resistant materials to extend the service life. The fixed connection between the clamping claw 104 and the positioning rod 102 has a high structural strength and can carry heavier tooling.

[0061] This arrangement can prevent the wheel hub tooling from accidentally slipping off, thereby improving safety, facilitating replacement of the clamping claws 104, reducing maintenance costs, and saving maintenance time.

[0062] Preferably, the bottom of the groove of the clamping claw 104 is arched upward, or the clamping claw 104 is formed by welding two parallel side walls at both ends of the diameter of a cylinder.

[0063] The upward arched design allows the hub tooling to be naturally guided to the center position during insertion, ensuring better positioning.

[0064] Preferably, the height of the claw 104 is smaller than the distance between the positioning hole on the hub tooling and the inner diameter.

[0065] This arrangement prevents the clamping claw 104 from being too high, so that the clamping claw 104 blocks the positioning hole on the hub tooling, hinders the blade root bolt from being inserted into the positioning hole, and affects the test assembly process.

[0066] Specifically, one side wall of the claw 104 is detachably connected, and the movable side wall is connected by bolts to form an integrated structure.

[0067] The arrangement of the clamping claw 104 can expand the width of the clamping claw 104 as required, has a wider range of uses, and facilitates the installation of the wheel hub tooling.

[0068] Specifically, the mobile bracket 2 includes a connecting plate 201, a first slider 202, a first slide rail 203, a connecting frame 204, a rolling wheel 205 and an adjusting rod 206. One side of the connecting plate 201 is connected to the connecting frame 204 and the first slider 202. The first slider 202 cooperates with the first slide rail 203 to form a sliding structure for adjusting the left and right position of the connecting plate 201. The connecting frame 204 is a rectangular frame structure. Rolling wheels 205 are provided at the four corners of the connecting frame 204 on the side away from the connecting plate 201. The rolling wheels 205 are used to disperse the pressure on the connecting plate 201 to the rotating beam 3. One end of the adjusting rod 206 is connected to the connecting frame 204 for adjusting the left and right position of the mobile bracket 2. The other end of the adjusting rod 206 is connected to the rotating beam 3.

[0069] The first slider 202 cooperates with the first slide rail 203 to form a sliding structure, allowing the connection plate 201 to be accurately adjusted in the left and right directions, ensuring that the hub tooling can be accurately aligned. The rolling wheels 205 arranged at the four corners of the connection frame 204 evenly disperse the pressure on the connection plate 201 to the rotating beam 3, reducing local stress concentration and improving the stability and durability of the overall structure. The connection plate 201 not only connects the first slider 202 and the connection frame 204, but also provides a solid foundation for the entire mobile bracket 2. The connection frame 204 with a rectangular frame structure provides a stable platform for installing other components and enhances the rigidity of the overall structure. The rolling wheels 205 enable the mobile bracket 2 to slide easily on the rotating beam 3, increasing the flexibility of operation and facilitating rapid position adjustment. The two ends of the adjustment rod 206 are respectively connected to the connection frame 204 and the rotating beam 3. The position adjustment of the connection frame 204 in the left and right directions is achieved by changing the length of the adjustment rod 206, which facilitates the trial installation of wind turbine blades and hub tooling.

[0070] This arrangement introduces a rolling wheel 205 to disperse the pressure, thereby solving the problem of local stress concentration that may exist in a traditional sliding structure. The uniform pressure distribution reduces material fatigue and wear, improves the device's ability to withstand the weight of the hub tooling, reduces the risk of accidents, and thus extends the service life of the mobile bracket 2 and related components.

[0071] Specifically, the connecting frame 204 is formed by welding two horizontal and two vertical square tubes.

[0072] By selecting the appropriate square tube size and welding process, the material usage can be reduced while ensuring sufficient strength, reducing costs and weight, reducing manufacturing difficulty and cost, and also helping to maintain high production accuracy.

[0073] Specifically, the contact surface between the first sliding block 202 and the first sliding rail 203 has a trapezoidal cross section.

[0074] The trapezoidal cross section increases the contact area and provides greater friction, making the first slider 202 more stable on the first slide rail 203, reducing shaking or deviation during sliding, reducing local stress concentration, thereby reducing the wear rate between the slider and the slide rail and extending the service life.

[0075] Specifically, the adjustment rod 206 is a telescopic rod, which may be a sleeve-type telescopic rod, a spiral-type telescopic rod, a scissors-type telescopic rod, a rack-and-pinion telescopic rod, or a coil spring-type telescopic rod.

[0076] Specifically, it also includes an adjusting rod 207 , and two ends of the adjusting rod 207 are respectively connected to the connecting frame 204 and the supporting rod 103 .

[0077] The adjusting rod 207 serves as a connecting piece, which enhances the structural stability between the connecting frame 204 and the support rod 103, ensuring that no unnecessary shaking or displacement occurs during operation. The relative position between the connecting frame 204 and the support rod 103 can be fine-tuned by adjusting the adjusting rod 207 to ensure accurate alignment of the hub tooling and the blade root bolts.

[0078] This setting provides an additional stable connection, enhances the reliability and safety of the entire system, reduces the risk of loosening or failure, and provides higher safety guarantees especially in heavy load or complex operating environments.

[0079] Specifically, the revolving crossbeam 3 includes a transverse beam 301, a revolving portion 302 and a push rod 303. The transverse beam 301 is a rectangular frame structure. Two revolving portions 302 are respectively arranged on both sides of the transverse beam 301. The revolving portion 302 is used to form a hinge with the lifting frame 4. One end of the push rod 303 is connected to the transverse beam 301 for pushing the revolving portion 302 to rotate. The other end of the push rod 303 is connected to the lifting frame 4.

[0080] The transverse beam 301 of the rectangular frame structure is the core part of the rotating crossbeam 3, providing a solid support platform and ensuring the stability of the entire device. The rotating part 302 forms a hinge structure with the lifting frame 4, so that the transverse beam 301 can rotate around the hinge point, realizing the angle adjustment of the hub tooling in the vertical direction. The hinge design between the rotating part 302 and the lifting frame 4 ensures the effective transmission of force, which is finally transmitted from the hub bracket 1 to the lifting frame 4 through the mobile bracket 2 and the rotating crossbeam 3, thereby enhancing the rigidity and stability of the overall structure. The push rod 303 controls the telescopic action of the push rod 303 through the connection with the transverse beam 301, and can push the rotating part 302 to rotate around the hinge point, thereby realizing the angle adjustment of the hub tooling in the vertical direction, and limiting the rotation of the rotating crossbeam 3 to avoid excessive rotation.

[0081] This setup allows for precise angle adjustment, increases flexibility and accuracy during assembly, helps improve work efficiency, has higher overall structural rigidity, and reduces the possibility of deformation.

[0082] Specifically, the push rod 303 can be a manual, electric drive unit, pneumatic drive unit or hydraulic drive unit.

[0083] Specifically, a surface of the connecting plate 201 away from the first sliding block 202 is connected to the fixing seat 101 , and a surface of the first sliding rail 203 away from the connecting plate 201 is connected to the transverse beam 301 .

[0084] By directly connecting the fixed seat 101 to the connecting plate 201, it is ensured that the hub bracket 1 can be accurately installed and maintain a stable position, which helps to achieve high-precision assembly. The cooperation between the first slide rail 203 and the first slider 202 allows the connecting plate 201 and the fixed seat 101 thereon to be accurately adjusted in the left and right directions, ensuring that the hub tooling can be accurately aligned. The side of the first slide rail 203 away from the connecting plate 201 is connected to the transverse beam 301, forming a continuous force transmission path, which is transmitted from the hub bracket 1 through the movable bracket 2 and finally to the transverse beam 301, ensuring the integrity and stability of the structure.

[0085] The stable connection structure of the arrangement reduces the risk of accidents and improves the safety of the device, and the modular design makes the various components easy to disassemble and replace, facilitating daily maintenance and overhaul work.

[0086] Specifically, the lifting frame 4 includes a first lifting beam 401, a second lifting beam 402, a sliding assembly 403, a driving member 404, a column 405 and a lifting seat 406. The two columns 405 are arranged on the lifting seat 406 in the vertical direction. The first lifting beam 401 and the lifting seat 406 are rectangular frame structures. The two ends of the first lifting beam 401 are respectively connected to the two columns 405 through the sliding assembly 403, and the two ends of the second lifting beam 402 are respectively connected to the lower parts of the two columns 405. The driving member 404 is arranged in the middle of the second lifting beam 402. The driving end of the driving member 404 is connected to the first lifting beam 401, which is used to control the up and down movement of the first lifting beam 401.

[0087] Two columns 405 are arranged on the lifting seat 406 in the vertical direction to provide solid support for the entire lifting frame 4, ensuring the stability and bearing capacity of the structure. The first lifting beam 401 is connected to the column 405 through the sliding component 403, and can move up and down under the control of the driving member 404 to adjust the height of the wheel hub tooling. The second lifting beam 402 is connected to the lower part of the column 405 to fix and support it, and at the same time provide an installation position for the driving member 404. The driving member 404 is arranged in the middle of the second lifting beam 402, and its driving end is connected to the first lifting beam 401, which is used to accurately control the up and down movement of the first lifting beam 401 to ensure the accuracy of height adjustment.

[0088] This setting makes the height adjustment more delicate and smooth, improves the flexibility and accuracy during assembly, enhances the rigidity of the overall structure, reduces the possibility of deformation, and reduces the risk of accidents.

[0089] Specifically, the first lifting beam 401 is provided with a protruding portion forwardly, and a rotating shaft is provided on the protruding portion along the left-right direction. The rotating shaft is used to form a hinged connection with the rotating portion 302 to adjust the angle of the rotating beam 3 .

[0090] The rotating shaft of the protrusion serves as a hinge point, ensuring a stable connection between the first lifting beam 401 and the rotating part 302, providing reliable rotation support, and through the hinge connection, the angle of the rotating beam 3 can be flexibly adjusted to meet different assembly requirements and operating conditions.

[0091] Preferably, the rotary shaft and the protruding portion can rotate relative to each other, and the rotation angle is a forward tilt angle.

[0092] Preferably, the forward inclination angle is generally within 1°.

[0093] Specifically, the sliding assembly 403 includes a second sliding block 4031 and a second sliding rail 4032 , and the cross-section of the matching surface of the second sliding block 4031 and the second sliding rail 4032 is trapezoidal.

[0094] The trapezoidal cross-section increases the contact area and provides greater friction, making the second slider 4031 more stable on the second slide rail 4032, reducing shaking or deviation during sliding, reducing local stress concentration, thereby reducing the wear rate between the slider and the slide rail and extending the service life.

[0095] Specifically, the second lifting beam 402, the column 405 and the lifting seat 406 are all made of I-beams.

[0096] I-beams have high bending strength and shear resistance, and can effectively enhance the rigidity and stability of the entire lifting frame 4, ensuring that it is not easily deformed when bearing heavy loads. It can reduce the amount of material used while ensuring sufficient strength, reduce its own weight, and facilitate transportation and installation.

[0097] This setup ensures the long-term stability and reliability of the structure, reduces maintenance needs and replacement frequency, simplifies the manufacturing process, and also facilitates transportation and on-site installation, helping to reduce production maintenance costs.

[0098] Specifically, the lifting frame 4 further includes a reinforcing rib 407 , and two ends of the reinforcing rib 407 are respectively connected to the column 405 and the lifting seat 406 , so as to enhance the structural rigidity of the lifting frame 4 .

[0099] By adding reinforcing ribs 407 between the columns 405 and the lifting seat 406, the rigidity and stability of the entire lifting frame 4 are effectively enhanced, the deformation when subjected to heavy loads or external forces is reduced, the pressure from the columns 405 and the lifting seat 406 is more evenly dispersed, the local stress concentration is reduced, and the overall bearing capacity of the structure is improved.

[0100] This setting improves the rigidity and load-bearing capacity of the structure, reduces the vibration and shaking of the system during operation, improves the overall stability and operating experience, and improves safety and reliability.

[0101] Specifically, the base 5 includes a load-bearing member 501 and a driving unit 502 . The driving unit 502 is disposed below the load-bearing member 501 to facilitate the movement of the wheel hub tooling.

[0102] The load-bearing member 501, as the core part of the base 5, provides a solid support platform to ensure the stability of the entire device during operation. The driving unit 502 is located below the load-bearing member 501. Through a driving mechanism such as electric, hydraulic or pneumatic, the base 5 and its upper structure can be easily moved, so that the wheel hub tooling can be quickly and accurately positioned to the desired position.

[0103] This setting greatly reduces the need for manual handling, improves work efficiency and reduces labor intensity.

[0104] Specifically, the load-bearing member 501 is two square tubes.

[0105] The square tube has high bending strength and shear resistance, which can effectively enhance the rigidity and load-bearing capacity of the load-bearing component 501, ensuring that it is not easily deformed when bearing heavy loads. In addition, the square tube is a standardized industrial material, which is easy to cut, drill and other processing operations, simplifying the manufacturing process, and also convenient for transportation and on-site installation.

[0106] Specifically, the driving unit 502 is four roller assemblies, which are used to facilitate the movement of the hub tooling.

[0107] The four roller assemblies are distributed on the four corners of the base 5, providing smooth movement capabilities, allowing the hub tooling to easily move between different positions, and can more evenly distribute the pressure from the load-bearing member 501, reducing local stress concentration and improving the overall bearing capacity of the structure. The roller assemblies are usually equipped with a locking or braking function, which can fix the position of the base 5 when necessary to ensure that the hub tooling can accurately reach the specified position.

[0108] It can also be configured to have a universal wheel design, allowing the base 5 to move in multiple directions, thereby increasing operational flexibility.

[0109] This setting reduces the frictional resistance with the ground, making movement easier, reducing the labor intensity of operators, enabling delicate and smooth movement, and improving flexibility and accuracy during assembly.

[0110] Specifically, the adjusting rod 206, the push rod 303, the driving member 404 and the driving unit 502 can be controlled by electric control, pneumatic control, hydraulic control, stepper motor control, servo motor control or wireless remote control, including wireless communication module, integrated control system, development control software and power management.

[0111] The arrangement of the adjustment rod 206, the push rod 303, the drive member 404 and the drive unit 502 can not only realize remote control or remote control, but also significantly improve the convenience and accuracy of operation. This intelligent transformation not only optimizes the operation process, but also prolongs the service life of the equipment, reduces maintenance costs, and ensures reliability and safety in various complex operating environments.

[0112] Another object of the present invention is to disclose a method for rapid test assembly of a wind turbine blade hub tooling, based on any of the above-mentioned devices for rapid test assembly of a wind turbine blade hub tooling, specifically comprising the following steps:

[0113] S1: The wheel hub tooling is mounted on the wheel hub bracket 1 by crane, and is initially positioned and fixed;

[0114] Ensure that the wheel hub tooling is safely and accurately installed in the designated position, providing a basis for subsequent adjustments.

[0115] S2: The operator moves the control drive unit 502 to align with the blade root, adjusts the lifting frame 4 to control the up and down movement of the hub tooling, adjusts the movable bracket 2 to control the left and right movement of the hub tooling, and adjusts the rotating crossbeam 3 to control the rotation angle change of the hub tooling. The position of the hub tooling is adjusted by multiple fine-tuning methods, and finally adjusted until the hub tooling and the blade root bolts can completely correspond;

[0116] Through multi-dimensional fine adjustment, the hub tooling and the blade root bolts are accurately aligned to improve assembly accuracy and efficiency.

[0117] S3: Control the hub test assembly device to move toward the blade direction through the driving unit 502 until all the bolts at the root of the blade are inserted into the designated position of the hub tooling according to the process requirements;

[0118] S4: If the test assembly is qualified, execute step S5; if the test assembly is unqualified, execute step S6;

[0119] S5: After the test assembly is completed, the operator controls the driving unit 502 to withdraw from the blade root to the adjustment area, and then adjusts the lifting frame 4, the movable bracket 2, the rotating beam 3 and the forward tilt angle to the initial position in sequence, and moves the hub test assembly device to the specified parking area;

[0120] S6: Control the driving unit 502 to withdraw from the blade root, trim the wind turbine blade, and execute step S3 after passing the inspection.

[0121] This setting ensures precise alignment of the hub tooling with the blade root bolts through multi-dimensional fine adjustment in directions such as up and down, left and right, and rotation, thereby improving assembly accuracy, clearly dividing the work among each step, reducing unnecessary repetitive operations, and improving overall work efficiency. It can also use electric, pneumatic, or hydraulic drive units for automatic control, which simplifies the operating process, reduces the need for manual intervention, improves the safety and accuracy of operations, and reduces the risk of accidents.

[0122] Specifically, the wheel hub tooling can be fixed on the wheel hub bracket 1 by bolts.

[0123] The bolt connection provides a solid fixing point to ensure that the wheel hub tooling will not move or shake during operation, making it easy to quickly remove and reinstall the wheel hub tooling. By selecting bolts of different lengths and specifications, it can adapt to different sizes and types of wheel hub tooling, enhancing the versatility of the system.

[0124] Specifically, when the hub tooling is aligned with the blade root bolts, four evenly distributed holes on the hub tooling are selected as a reference for adjustment.

[0125] By using four holes as a reference, multiple positions can be calibrated at the same time to ensure the precise alignment of the hub tooling with the blade root bolts and reduce the impact of single-point errors. The four holes are evenly distributed on the hub tooling, providing multiple stable support points, ensuring the stability of the entire tooling during the adjustment process, and can quickly determine the position of the hub tooling, reducing the time for trial and error and improving alignment efficiency.

[0126] Specifically, the adjustment area is a safe and vast area.

[0127] The wide area ensures that there is enough space for multi-dimensional adjustment of the wheel hub tooling, such as up and down, left and right, and rotation, avoiding operational difficulties or errors caused by insufficient space, reducing the risk of collision between operators and equipment, providing a larger safety buffer zone, and allowing more flexible arrangement of various auxiliary equipment, such as cranes, tool racks, etc., improving work efficiency and operational convenience, and accommodating more operators to work at the same time, facilitating team collaboration and communication, and improving overall work efficiency.

[0128] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
