Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, and more specifically to a wind turbine blade carbon beam rotating device. Background Technology

[0002] As the global energy structure shifts towards cleaner and lower-carbon energy, wind power, as a technologically mature and highly sustainable renewable energy source, has become one of the core forces driving this energy transition. Furthermore, wind power has formed two main development directions: onshore and offshore wind power. These two types of wind power rely on different geographical environments and resource endowments, jointly supporting the large-scale expansion of the wind power industry. However, the development of onshore wind power is significantly constrained by terrain, wind speed stability, and land resources. Compared to onshore wind power, offshore wind power possesses unique advantages such as abundant wind energy resources, higher and more stable wind speeds, and no land occupation, thus offering broad development prospects.

[0003] However, the operating conditions of offshore wind turbines are more severe than those on land, mainly in the following aspects: First, the wind speed is high, the turbulence is strong, and the wind load is severe at sea. The blades need to withstand high-frequency alternating loads for a long time, which places extremely high demands on the fatigue resistance of the blades. Second, the high salt spray, high humidity, and strong ultraviolet radiation environment at sea can easily lead to material aging and corrosion, which can significantly shorten the service life of the blades. Third, as the blade length continues to increase, the aerodynamic load and bending moment borne by the main beam increase exponentially. The blades must have both high rigidity and lightweight design to facilitate offshore installation.

[0004] Therefore, the performance shortcomings of wind turbine blades using fiberglass beams in offshore conditions are becoming increasingly apparent, while wind turbine blades using carbon beams, with their unique material properties, have become the optimal choice for offshore wind power conditions. During processing, carbon beams are generally first pultruded, followed by post-processing such as surface polishing and applying a protective coating.

[0005] During post-processing, carbon beams need to be rotated to facilitate surface and edge treatment. However, currently, beam rotation relies heavily on manual labor and overhead cranes. Firstly, while carbon beams are long, heavy, and tough, their localized impact and deformation resistance is weak. Manual rotation with an overhead crane makes them prone to damage, and uneven stress distribution across multiple lifting points can lead to stress concentration, causing delamination of the carbon fiber layers, surface microcracks, and other hidden damage, posing quality risks and potentially leading to blade failure during subsequent use. Secondly, rotating carbon beams with multiple people using an overhead crane requires significant manpower but is time-consuming and inefficient. Summary of the Invention

[0006] This invention provides a wind turbine blade carbon beam rotation device to solve the problems of carbon beam damage caused by manual rotation of wind turbine blade carbon beams by overhead crane, as well as low work efficiency despite high manpower consumption.

[0007] In a first aspect, the present invention provides a wind turbine blade carbon beam rotating device, comprising: Multiple rotating devices are spaced apart along a first direction, and carbon beams are adapted to be mounted on the multiple rotating devices, with the extending direction of the carbon beams parallel to the first direction; The rotating device includes a mounting frame and a rotating assembly. The mounting frame is fixedly disposed on the mounting surface, and the rotating assembly is rotatably disposed on the mounting frame. The rotating assembly includes a first rotating member, a second rotating member, and a locking mechanism. One end of the first rotating member is hinged to one end of the second rotating member, and the other end of the first rotating member is locked or released from the other end of the second rotating member by the locking mechanism. A first clamping member is disposed on the first rotating member, and a second clamping member is disposed on the second rotating member. The first clamping member and the second clamping member are adapted to clamp the carbon beam from both sides of the carbon beam. The drive assembly includes: multiple bases, multiple drive components, and multiple sets of transmission mechanisms. One base is provided between every two of the rotating devices, and one drive component is provided on each base. The output end of the drive component is connected to the power input end of a set of transmission mechanisms, and the two power output ends of each set of power transmission components are respectively connected to two adjacent rotating assemblies. When the other end of the first rotating member in each of the rotating devices is locked to the other end of the second rotating member, the plurality of driving members drive the plurality of rotating components to rotate synchronously through the transmission mechanism, thereby causing the clamped carbon beam to rotate.

[0008] Beneficial effects This invention achieves multi-point synchronous clamping and fixing of the carbon beam by arranging multiple rotating devices at intervals along its extension direction. This replaces the traditional method of manually lifting and turning the carbon beam using an overhead crane. The first and second clamping components of each rotating device apply force evenly to clamp the carbon beam from both sides. Furthermore, the rotating components of multiple rotating devices rotate synchronously under the control of multiple driving components. This prevents the carbon beam from bending, twisting, or shifting due to uneven force distribution during rotation, unlike traditional turning methods that can cause damage. This invention effectively disperses the stress on the carbon beam, avoiding stress concentration caused by uneven force distribution at a single point or in a localized area. It fundamentally prevents latent damage such as carbon fiber delamination and surface microcracks, eliminating potential failure hazards during subsequent blade use and ensuring the structural integrity and service life of the carbon beam.

[0009] Furthermore, by synchronously driving multiple rotating components through the drive unit, the carbon beam rotation operation is automated, eliminating the need for multiple people to operate the overhead crane, thus improving the level of automation in construction, significantly reducing the time spent on carbon beam flipping, and increasing work efficiency.

[0010] In one optional embodiment, along the width direction of the carbon beam, a side support is also provided on one side of the mounting frame, and a lifting device is provided on the side support. The first rotating member and the second rotating member are provided with lifting holes. When the other end of the first rotating member is released from the other end of the second rotating member, the lifting device connects to the lifting hole and drives the first rotating member or the second rotating member to rotate around the hinge point, thereby changing the opening between the first rotating member and the second rotating member.

[0011] Beneficial effects When it is necessary to install or dismantle carbon beams or perform post-processing work on carbon beams, the first or second rotating component can be lifted by a lifting device to increase the opening between the first and second rotating components, making it easier for workers to operate.

[0012] In one optional embodiment, a rod is provided on the first rotating member, the axial direction of the rod is along the first direction, and a limiting mechanism is also provided on the side of the side support facing the rotating assembly. The limiting mechanism is adapted to engage with the rod to restrict the first rotating member from rotating around the hinge point.

[0013] In one optional embodiment, the limiting mechanism includes: a fixed seat and a plug rod, two fixed seats are spaced apart on the side support along the first direction, each fixed seat is provided with a plug hole, the plug rod is inserted into the plug hole, and the rod body is adapted to abut against the side of the plug rod facing the side support.

[0014] Beneficial effects After setting the limit mechanism, the position of the first rotating component can be maintained during the installation and disassembly of the carbon beam, preventing rotation and thus ensuring the safety of the construction operation.

[0015] In one optional embodiment, the transmission mechanism includes: a power transmission component and a rotational transmission component; The power transmission component includes: a first transmission gear, a second transmission gear, a first rotating shaft, two first gear mounting seats, and two transmission rods. The driving component is a servo motor. The output end of the servo motor is connected to the first transmission gear. The two first gear mounting seats are spaced apart on the base along a first direction. Both ends of the first rotating shaft are connected to the two first gear mounting seats. The second transmission gear is disposed on the first rotating shaft and meshes with the first transmission gear. Both ends of the first rotating shaft are respectively connected to one end of the two transmission rods through universal couplings. The rotating transmission component includes: two second gear mounting seats, a driving gear, a second rotating shaft, two third gear mounting seats, a driven gear, a third rotating shaft, and a gear ring. Two second gear mounting seats are spaced apart along a first direction on the mounting frame. The second rotating shaft is connected to the two second gear mounting seats. The driving gear is mounted on the second rotating shaft. The other end of each transmission rod is connected to a second rotating shaft via a universal coupling. Two third gear mounting seats are also spaced apart along the first direction on the mounting frame. The third rotating shaft is connected to the two third gear mounting seats. The driven gear is mounted on the third rotating shaft. The gear ring is located on the outer edge of the rotating component and meshes with the driving gear and the driven gear.

[0016] Beneficial effects Multiple servo motors drive the operation of multiple rotating devices. Utilizing servo motors as high-precision drive components ensures that the rotational speed and angle of multiple rotating components are completely consistent, preventing torsion, misalignment, and interlayer damage to the carbon beam due to asynchronous rotation, thus improving the rotational posture accuracy of the carbon beam. Universal couplings at both ends of the transmission rod enable stable power transmission over long distances and effectively compensate for axial deviations caused by installation errors, uneven mounting surfaces, and carbon beam deflection, preventing rigid transmission from jamming or excessive wear, resulting in enhanced equipment reliability.

[0017] In one optional embodiment, the mounting bracket is provided with a high-pressure air nozzle for blowing away the driving gear, the driven gear, and the gear ring.

[0018] Beneficial effects By setting high-pressure air nozzles, the tooth structure on the drive gear, driven gear, and gear ring can be blown away as needed, timely removing dust, grinding debris, and oil stains, ensuring the cleanliness of the drive gear, driven gear, and gear ring, preventing impurities from adhering, avoiding impurities from entering the meshing gap and causing tooth surface wear, jamming, or a decrease in transmission accuracy, and extending the service life of the drive gear, driven gear, and gear ring.

[0019] In one optional embodiment, the wind turbine blade carbon beam rotating device further includes multiple sets of guide components, which are spaced apart on the mounting frame along the rotation direction of the rotating component. Each guide component includes two mounting seats and two guide wheels. The two mounting seats are arranged on both sides of the rotating component along the first direction, and each mounting seat has a guide wheel rotatably mounted on it. The guide wheel makes rolling contact with the surface of the rotating component.

[0020] Beneficial effects After the guide component is installed, it can not only limit and fix the rotating component from both sides to prevent axial movement and make the rotating component rotate more smoothly and without shaking, but also play a guiding role to guide the rotating component to rotate smoothly.

[0021] In one optional embodiment, the first clamping member includes: a first connecting body and a first elastic body, the first connecting body being connected to the first rotating member, the first connecting body being provided with the first elastic body, and the end face of the first elastic body being a convex surface; The second clamping member includes: a second connecting body and a second elastic body, the second connecting body being connected to the second rotating member, the second connecting body being provided with the second elastic body, and the end face of the second elastic body being concave; Furthermore, the convex and concave surfaces are adapted to the surface of the carbon beam.

[0022] Beneficial effects The elastic properties of the first and second elastic elements ensure that the carbon beam is firmly clamped without damaging the contact surface. Furthermore, the convex surface of the first elastic element and the concave surface of the second elastic element perfectly match the surface morphology of the carbon beam, resulting in more stable clamping and preventing circumferential slippage during the rotation of the carbon beam.

[0023] In one optional embodiment, the first rotating member has two connecting parts, each connecting part being provided with an adjustment hole, and each end of the first connecting body is provided with a first connecting hole, and each first connecting hole and a corresponding adjustment hole are provided with a fastener; and / or; The second rotating part has two connecting parts, and the connecting parts are provided with adjustment holes. Both ends of the second connecting body are provided with a second connecting hole. Each second connecting hole and a corresponding adjustment hole are provided with a fastener. The distance between the first elastomer and the second elastomer can be changed by altering the position of the fastener in the adjustment hole.

[0024] Beneficial effects By setting the first fastener in different first adjustment holes and / or the second fastener in different second adjustment holes, the distance between the first elastic body and the second elastic body can be changed, thereby adapting to carbon beams of different sizes and making the equipment more versatile.

[0025] In one optional embodiment, the locking mechanism includes: a hanging plate, a fixed plate, an operating handle, and a hanging ring. The first rotating member is provided with the hanging plate, and the hanging plate is provided with a slot. One end of the operating handle is hinged to the fixed plate, and a hanging ring is hinged to the operating handle. One end of the hanging ring can be engaged with the slot.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Compared to traditional fiberglass wind turbines, carbon fiber blades, thanks to the unique advantages of carbon fiber materials, can be precisely adapted to the harsh operating conditions of offshore wind power. The tensile modulus of carbon fiber can reach 230-300 GPa, which is 3-4 times that of fiberglass, while its density is only 1.7-1.8 g / cm³, far lower than the 2.5 g / cm³ of fiberglass. Its low density and high modulus characteristics enable the wind turbine blades to be lightweight and highly rigid.

[0031] However, with the increasing size of wind turbine units, some wind turbine blades can have carbon beams reaching up to 130 meters, which presents challenges for the post-processing of these beams. The traditional method of multiple people working with overhead cranes to lift and rotate the carbon beams at multiple points is difficult to quantify and control in terms of synchronization and coordination. The lack of strong constraints during lifting makes collisions more likely, and the uneven stress distribution across multiple lifting points can lead to localized stress concentrations in the carbon beams. This can cause hidden damage such as delamination of the carbon fiber layers and surface microcracks, posing quality risks and potentially leading to blade failure during subsequent use. Furthermore, this method has low automation, relies heavily on manual labor, and is time-consuming for each rotation, resulting in low work efficiency.

[0032] The following is combined with Figures 1 to 19 The following describes embodiments of the present invention.

[0033] According to an embodiment of the present invention, in one aspect, a wind turbine blade carbon beam rotating device is provided, comprising: Multiple rotating devices 1 are spaced apart along a first direction, and carbon beams 2 are adapted to be mounted on the multiple rotating devices 1, with the extending direction of the carbon beams 2 being parallel to the first direction; The rotating device 1 includes a mounting frame 11 and a rotating assembly 12. The mounting frame 11 is fixedly disposed on the mounting surface, and the rotating assembly 12 is rotatably disposed on the mounting frame 11. The rotating assembly 12 includes a first rotating member 121, a second rotating member 122, and a locking mechanism 123. One end of the first rotating member 121 is hinged to one end of the second rotating member 122, and the other end of the first rotating member 121 is locked or released from the other end of the second rotating member 122 through the locking mechanism 123. A first clamping member 124 is disposed on the first rotating member 121, and a second clamping member 125 is disposed on the second rotating member 122. The first clamping member 124 and the second clamping member 125 are adapted to clamp the carbon beam 2 from both sides. The drive assembly 3 includes: multiple bases 31, multiple drive components 32 and multiple sets of transmission mechanisms. A base 31 is provided between every two rotating devices 1. A drive component 32 is provided on each base 31. The output end of the drive component 32 is connected to the power input end of a set of transmission mechanisms. The two power output ends of each set of power transmission components are respectively connected to two adjacent rotating assemblies 12. When the other end of the first rotating member 121 in each rotating device 1 is locked with the other end of the second rotating member 122, the multiple driving members 32 drive the multiple rotating components 12 to rotate synchronously through the transmission mechanism, so as to drive the clamped carbon beam 2 to rotate.

[0034] like Figure 1 As shown, multiple rotating devices 1 are arranged in a row at intervals along the extension direction of the carbon beam 2, and the number of rotating devices 1 needs to be selected according to the length of the carbon beam 2. Since the structure of each rotating device 1 is the same, the number of rotating devices 1 can be adjusted to handle carbon beams 2 of different sizes.

[0035] The rotating device 1 includes a mounting frame 11 and a rotating assembly 12. Specifically, the mounting frame 11 is directly mounted on a mounting surface, such as a relatively flat surface like a workshop floor. The mounting frame 11 includes a main support frame and four diagonal support members located at the corners of the main support frame. Along a first direction, two of the diagonal support members are positioned opposite the other two diagonal support members, forming a mounting gap. The lower part of the rotating assembly 12 is located within this mounting gap. Furthermore, multiple base plates are provided at the bottom end of the main support frame, with holes on the base plates to facilitate fixing to the mounting surface using bolts or other anchors.

[0036] The overall shape of the rotating assembly 12 is approximately circular, which facilitates rotation. Specifically, the shapes of the first rotating member 121 and the second rotating member 122 are approximately semi-circular. One end of the first rotating member 121 and one end of the second rotating member 122 are hinged together by a hinge shaft, while the other end of the first rotating member 121 and the other end of the second rotating member 122 are controlled by a locking mechanism 123. The connection state can be locked or released.

[0037] Specifically, such as Figure 1 As shown, a base 31 is provided between every two rotating devices 1, and the base 31 can be fixed to the mounting surface with reference to the mounting bracket 11. The driving component 32 is preferably a servo motor, and the power output by the servo motor is transmitted to the rotating components 12 of the two adjacent rotating devices 1 through the transmission mechanism. That is, each servo motor can drive the rotating components 12 of the two adjacent rotating devices 1 to rotate.

[0038] When it is not necessary to clamp the carbon beam 2, or when it is not necessary to rotate the carbon beam 2, the other end of the first rotating member 121 and the other end of the second rotating member 122 are in a released state. That is, at this time, they can rotate freely around the hinge axis, thereby changing the opening (i.e., the included angle) between them. This facilitates the installation of the carbon beam 2 on the rotating device 1, or the transfer of the rotated carbon beam 2 to another setting for processing, or the removal of the carbon beam 2 after post-processing on the rotating device 1. When it is necessary to clamp the carbon beam 2, or when the carbon beam 2 needs to be rotated, the first rotating member 121 or the second rotating member 122 needs to rotate around the hinge axis so that the first clamping member 124 and the second clamping member 125 contact and clamp the carbon beam 2 from the upper and lower sides. Then, the other end of the first rotating member 121 and the other end of the second rotating member 122 are locked together to prevent the rotating assembly 12 from loosening during rotation, which would cause the carbon beam 2 to fall off the rotating assembly 12 and be damaged.

[0039] Furthermore, when the carbon beam 2 needs to rotate, the first clamping member 124 and the second clamping member 125 clamp the carbon beam 2, and then the first rotating member 121 and the second rotating member 122 are locked together. Then, multiple driving members 32 output power, which is transmitted through the transmission mechanism to drive multiple rotating components 12 in multiple rotating devices 1 to rotate synchronously. As a result, the carbon beam 2 as a whole also rotates with the rotation of multiple rotating components 12, changing its angle and posture.

[0040] Multiple rotating devices 1 are spaced apart along the extension direction of the carbon beam 2, enabling simultaneous clamping and fixing of the carbon beam 2 at multiple points. Furthermore, the first clamping member 124 and the second clamping member 125 of each rotating device 1 apply force from both sides of the carbon beam 2, resulting in a large contact area and uniform force distribution. During flipping, the drive assembly 3 drives the rotation, and the rotating components 12 in the multiple rotating devices 1 rotate synchronously, providing more precise control and higher synchronization. This reduces the likelihood of uneven force distribution at multiple points causing bending, twisting, or positional displacement, which could damage the carbon beam 2. Moreover, the operation is highly automated, relying less on manual labor, greatly improving work efficiency and saving manpower and time costs.

[0041] In some embodiments, the transmission mechanism includes: a power transmission component and a rotational transmission component; The power transmission component includes: a first transmission gear 331, a second transmission gear 332, a first rotating shaft 333, two first gear mounting seats 334, and two transmission rods 335. The output end of the servo motor is connected to the first transmission gear 331. The two first gear mounting seats 334 are spaced apart on the base 31 along a first direction. The two ends of the first rotating shaft 333 are connected to the two first gear mounting seats 334. The second transmission gear 332 is mounted on the first rotating shaft 333 and meshes with the first transmission gear 331. The two ends of the first rotating shaft 333 are respectively connected to one end of the two transmission rods 335 through universal couplings 336. The rotating transmission component includes: two second gear mounting seats 341, a driving gear 342, a second rotating shaft 343, two third gear mounting seats 344, a driven gear 345, a third rotating shaft 346, and a gear ring 347. Two second gear mounting seats 341 are spaced apart along a first direction on the mounting frame 11. The second rotating shaft 343 is connected to the two second gear mounting seats 341. The driving gear 342 is mounted on the second rotating shaft 343. The other end of each transmission rod 335 is connected to a second rotating shaft 343 through a universal coupling 336. Two third gear mounting seats 344 are also spaced apart along the first direction on the mounting frame 11. The third rotating shaft 346 is connected to the two third gear mounting seats 344. The driven gear 345 is mounted on the third rotating shaft 346. The gear ring 347 is located on the outer edge of the rotating assembly 12 and meshes with the driving gear 342 and the driven gear 345.

[0042] Furthermore, the servo motors possess high control precision, enabling multiple servo motors to synchronously drive multiple rotating components 12. The servo motors are directly fixed to the mounting base 181, and two first gear mounting bases 334 are spaced apart on the base 31 along a first direction. A first transmission gear 331 is provided at the output end of the servo motor. The two ends of the first rotating shaft 333 are respectively connected to bearings on the two first gear mounting bases 334, and a second transmission gear 332 is mounted on the first rotating shaft 333. The first transmission gear 331 and the second transmission gear 332 mesh, with the first transmission gear 331 being a pinion and the second transmission gear 332 being a gear, thus reducing the output speed of the servo motor. A cover 337 can be provided on the outside of the first transmission gear 331 and the second transmission gear 332, and the cover 337 is detachably connected to the base 31. The cover 337 protects the first transmission gear 331 and the second transmission gear 332. Both ends of the first rotating shaft 333 are connected to a transmission rod 335 through a universal coupling 336. The end of each transmission rod 335 away from the servo motor is connected to a rotating transmission component through a universal coupling 336, so that the power output by the servo motor is transmitted to the rotating transmission component and drives the rotating assembly 12 to rotate.

[0043] Furthermore, such as Figures 7 to 11As shown, each rotating device 1 is equipped with a set of rotational transmission components. Along the second direction, i.e., the width direction of the carbon beam 2, the second gear mounting base 341 and the third gear mounting base 344 are respectively located on both sides of the bottom end of the rotating assembly 12. The two second gear mounting bases 341 are spaced apart along the first direction on both sides of the rotating assembly 12, and the two third gear mounting bases 344 are also spaced apart along the first direction on both sides of the rotating assembly 12. The driving gear 342 is mounted on the second rotating shaft 343, and both ends of the second rotating shaft 343 are connected to bearings on the second gear mounting base 341. One end of the second rotating shaft 343 is connected to the end of a transmission rod 335 away from the servo motor via a universal coupling 336. The servo motor outputs power to drive the driving gear 342 to rotate. The driven gear 345 is mounted on the third rotating shaft 346, and both ends of the third rotating shaft 346 are connected to bearings on the third gear mounting base 344. The outer edge of the rotating component 12 is provided with a gear ring 347, that is, a semi-circular gear ring 347 is provided on the first rotating component 121 and a semi-circular gear ring 347 is also provided on the second rotating component 122. The tooth structure on the gear ring 347 meshes with the driving gear 342 and the driven gear 345. When the servo motor outputs power to drive the driving gear 342 to rotate, it can drive the gear ring 347 to rotate, thereby driving the driven gear 345 to rotate.

[0044] In some embodiments, the mounting bracket 11 is provided with a high-pressure air nozzle 110 for blowing away the driving gear 342, driven gear 345 and gear ring 347.

[0045] Multiple high-pressure air nozzles 110 can be installed at the bottom of the mounting bracket 11. The jet direction of the high-pressure air nozzles 110 can be fixed or adjustable. Specifically, in this embodiment, as shown... Figure 19 As shown, high-pressure air nozzles 110 are provided at both the driving gear 342 and the driven gear 345. The air outlets of the two high-pressure air nozzles 110 are respectively directed towards the meshing points of the driving gear 342, driven gear 345, and gear ring 347. The high-pressure air nozzles 110 can be connected to an external air circuit to use supplied compressed air to blow away dust, grinding debris, and oil stains from the tooth structure and meshing surfaces of the driving gear 342, driven gear 345, and gear ring 347, ensuring the transmission efficiency of the driving gear 342, driven gear 345, and gear ring 347 and extending their service life.

[0046] In some embodiments, the wind turbine blade carbon beam rotating device further includes multiple sets of guide components 18, which are spaced apart on the mounting frame 11 along the rotation direction of the rotating component 12. The guide components 18 include two mounting seats 181 and two guide wheels 182. The two mounting seats 181 are arranged on both sides of the rotating component 12 along a first direction. Each mounting seat 181 is rotatably provided with a guide wheel 182, and the guide wheel 182 is in rolling contact with the surface of the rotating component 12.

[0047] Specifically, multiple sets of guide components 18 are arranged at intervals along the rotation direction of the rotating component 12, or in other words, circumferentially spaced around the rotating component 12. In this embodiment, at the bottom of the mounting bracket 11, corresponding to... Figure 3 Three sets of guide components 18 are provided at the bottom of the second rotating member 122 and on both sides of the top of the mounting bracket 11 (along the second direction), corresponding to the top sides of the second rotating member 122.

[0048] Furthermore, in each set of guide components 18, the mounting base 181 is fixedly mounted on the mounting frame 11, and a rotating shaft can be set on the mounting frame 11, with the guide wheel 182 rotatably mounted on the rotating shaft. The guide wheel 182 is in contact with the side of the rotating component 12, and when the rotating component 12 rotates, it drives the guide wheel 182 to rotate, with rolling friction between the two.

[0049] By setting the guide component 18 to limit and guide the rotating component 12, the rotating component 12 rotates more smoothly.

[0050] In some embodiments, the first clamping member 124 includes: a first connecting body 1241 and a first elastic body 1242. The first connecting body 1241 is connected to the first rotating member 121. The first elastic body 1242 is provided on the first connecting body 1241, and the end face of the first elastic body 1242 is a convex surface. The second clamping member 125 includes: a second connecting body 1251 and a second elastic body 1252. The second connecting body 1251 is connected to the second rotating member 122. The second elastic body 1252 is provided on the second connecting body 1251. The end face of the second elastic body 1252 is concave. Furthermore, the convex and concave surfaces are adapted to the surface of carbon beam 2.

[0051] Specifically, such as Figure 12 , Figure 15 As shown, the special shapes of the first elastic body 1242 and the second elastic element are designed to match the shape of the carbon beam 2, thereby achieving a better clamping effect. The convex surface of the first elastic body 1242 is suitable for contacting the concave side of the carbon beam 2, and the concave surface of the second elastic element is suitable for contacting the convex side of the carbon beam 2. This provides a larger contact area between the elastic body and the carbon beam 2, resulting in more uniform force distribution on the surface of the carbon beam 2 during clamping, preventing localized compression of the carbon beam 2. Furthermore, the curved surfaces also provide a more stable clamping effect.

[0052] Furthermore, in this embodiment, both the first elastic body 1242 and the second elastic body 1252 are rubber bodies. The rubber body will not cause scratches when in contact with the surface of the carbon beam 2, and at the same time, the friction is relatively large. More importantly, the rubber body is elastic, so it will not squeeze and damage the surface of the carbon beam 2 during clamping, thus preventing damage to the carbon fiber layer.

[0053] In some embodiments, the first rotating member 121 has two connecting portions 19, and the connecting portions 19 are provided with adjustment holes 191. Both ends of the first connecting body 1241 are provided with a first connecting hole 1243, and each first connecting hole 1243 and a corresponding adjustment hole 191 are provided with a fastener. and / or; The second rotating member 122 has two connecting parts 19, and the connecting parts 19 are provided with adjustment holes 191. Both ends of the second connecting body 1251 are provided with a second connecting hole 1253. Each second connecting hole 1253 and a corresponding adjustment hole 191 are provided with a fastener. The distance between the first elastic body 1242 and the second elastic body 1252 is changed by altering the position of the fastener in the adjustment hole 191.

[0054] Specifically, such as Figure 2 , Figure 5 , Figure 12 , Figure 15 As shown, in this embodiment, the two ends of the first connecting body 1241 are respectively connected to two connecting portions 19 on the first rotating member 121. Both ends of the first connecting body 1241 have first connecting holes 1243, while the connecting portions 19 have adjusting holes 191. Specifically, in this embodiment, both the first connecting hole 1243 and the adjusting hole 191 are elongated holes, but their extending directions are perpendicular. That is, when projected from the first direction, the first connecting hole 1243 and the adjusting hole 191 intersect in a cross shape. The fasteners are a bolt and a nut. One end of the bolt passes through the first connecting hole 1243 and the adjusting hole 191, and a nut is used to lock it in place. Thus, the first connecting body 1241 can be fixed using these two fasteners. Simultaneously, by changing the position of the bolt in the adjusting hole 191, the relative distance between the first elastic body 1242 and the second elastic body 1252 can be changed, thereby adapting to clamping carbon beams 2 of different thicknesses. The position of the first elastic body 1242 in the second direction can also be changed by changing the position of the bolt in the first connecting hole 1243.

[0055] Similarly, both ends of the second connecting body 1251 are connected to two connecting portions 19 on the second rotating member 122. Both ends of the second connecting body 1251 have second connecting holes 1253, while the connecting portions 19 have adjusting holes 191. Both the second connecting holes 1253 and the adjusting holes 191 are elongated holes, but their extending directions are perpendicular. That is, when projected from the first direction, the second connecting holes 1253 and 191 intersect in a cross shape. The fasteners are bolts and nuts. One end of the bolt passes through the second connecting hole 1253 and the adjusting hole 191, and is locked with a nut. Thus, the second connecting body 1251 can be fixed using these two fasteners. Simultaneously, by changing the position of the bolt in the adjusting hole 191, the relative distance between the first elastic body 1242 and the second elastic body 1252 can be changed, thereby adapting to clamping carbon beams 2 of different thicknesses. Furthermore, by changing the position of the bolt in the second connecting hole 1253, the position of the second elastic body 1252 in the second direction can be changed.

[0056] In another embodiment, the first connecting hole 1243 and the second connecting hole 1253 may also be round holes instead of oblong holes, that is, the positions of the first elastic body 1242 and the second elastic body 1252 in the second direction are not adjustable.

[0057] In other embodiments, the adjustment hole 191 (elongated hole) may be provided only on one of the first rotating member 121 and the second rotating member 122, while the other member may be provided with a round hole instead of the adjustment hole 191. This also allows for adjustment of the relative distance between the first elastic body 1242 and the second elastic body 1252.

[0058] In some embodiments, the locking mechanism 123 includes: a hanging plate 1231, a fixing plate 1232, an operating handle 1233, and a hanging ring 1234. The first rotating member 121 is provided with the hanging plate 1231, and the hanging plate 1231 is provided with a slot. One end of the operating handle 1233 is hinged to the fixing plate 1232, and the operating handle 1233 is hinged to the hanging ring 1234. One end of the hanging ring 1234 can be engaged with the slot.

[0059] Specifically, such as Figure 13 , Figure 14As shown, the hanging plate 1231 is fixedly mounted on the first rotating member 121, and the hanging plate 1231 has an arc-shaped groove. The fixing plate 1232 is mounted on the second rotating member 122, and the operating handle 1233 is hinged to the fixing plate 1232, so that the operator can rotate the operating handle 1233 by applying force to the handle. The hanging ring 1234 is hinged to the operating handle 1233, and the hinge position is located on the side of the hinge position between the operating handle 1233 and the fixing plate 1232 away from the hanging plate 1231. When the operating handle 1233 is rotated upward, the hanging ring 1234 can be hung in the groove. Then, when the operating handle 1233 is rotated downward, the hanging ring 1234 is firmly connected to the groove, which locks the other end of the first rotating member 121 and the other end of the second rotating member 122 together.

[0060] Furthermore, such as Figure 14 As shown, the locking mechanism 123 also includes a limit handle 1235. A limit plate is provided at the end of the fixed plate 1232 away from the hanging plate 1231, and a limit hole is provided on it. The limit handle 1235 is hinged to the operating handle 1233, and the hook 1236 at one end can be engaged into the limit hole.

[0061] In some embodiments, along the width direction of the carbon beam 2, a side support frame 13 is also provided on one side of the mounting frame 11, a lifting device 14 is provided on the side support frame 13, and a lifting hole 15 is provided on the first rotating member 121 and the second rotating member 122. When the other end of the first rotating member 121 is released from the other end of the second rotating member 122, the lifting device 14 connects to the lifting hole 15 and drives the first rotating member 121 or the second rotating member 122 to rotate around the hinge point, so as to change the opening between the first rotating member 121 and the second rotating member 122.

[0062] Specifically, such as Figures 2 to 4 As shown, in this embodiment, along the second direction, one side of the mounting frame 11 is the feeding side, and the other side of the mounting frame 11 is provided with a side support frame 13. The lifting device 14 is preferably an electric hoist, which is set on the top of the side support frame 13. Lifting holes 15 are provided on the first rotating member 121 and the second rotating member 122. The hook of the electric hoist is connected to the lifting hole 15, and then the electric hoist is started to lift or lower the first rotating member 121 or the second rotating member 122. The opening between the first rotating member 121 and the second rotating member 122 increases or decreases accordingly.

[0063] Only manual hooking or unhooking is required. The first rotating part 121 or the second rotating part 122 can be lifted or lowered by the lifting device 14, i.e., the electric hoist, which saves labor costs and improves work efficiency.

[0064] In some embodiments, a rod 16 is provided on the first rotating member 121, the axial direction of the rod 16 is along a first direction, and a limiting mechanism 17 is also provided on the side of the side support 13 facing the rotating assembly 12. The limiting mechanism 17 is adapted to engage with the rod 16 to restrict the first rotating member 121 from rotating around the hinge point.

[0065] Specifically, in this embodiment, the first rotating member 121 is provided with rods 16 that penetrate its two side walls. When the first rotating member 121 rotates towards the side support 13, it can abut against the rods 16 through the limiting mechanism 17 to limit the rotation of the first rotating member 121, while keeping the opening between the first rotating member 121 and the second rotating member 122 unchanged, which facilitates the loading operation by the staff and ensures the safety of the operation process.

[0066] In some embodiments, the limiting mechanism 17 includes: a fixed seat 171 and a plug rod 172. The two fixed seats 171 are spaced apart on the side frame 13 along a first direction. Each fixed seat 171 is provided with a plug hole. The plug rod 172 is inserted into the plug hole, and the rod body 16 is adapted to abut against the side of the plug rod 172 facing the side frame 13.

[0067] Specifically, such as Figure 4 As shown, when it is necessary to limit the rotation of the first rotating component 121, the lifting device 14 rotates the first rotating component 121 towards the side support 13. After the rod 16 rotates past the insertion hole, the insertion rod 172 is inserted into the insertion hole, so that the two ends of the rod 16 abut against the two insertion rods 172, thereby limiting the rotation of the first rotating component 121. After the insertion rod 172 is pulled out of the insertion hole, the first rotating component 121 can be lowered again by the lifting device 14 and rotated towards the second rotating component 122.

[0068] The following is a description of the usage process of the wind turbine blade carbon beam rotating device provided in this embodiment: like Figure 2 As shown, the first rotating member 121 is on top and the second rotating member 122 is below in the initial state.

[0069] When the carbon beam 2 needs to be rotated, the first rotating component 121 and the second rotating component 122 are released. The operator connects the hook of the lifting device 14 to the lifting hole 15, and then drives the first rotating component 121 to rotate around the hinge axis. After reaching the appropriate position, the insertion rod 172 is inserted into the insertion hole, and then the two ends of the rod body 16 abut against the two insertion rods 172. The first rotating component 121 achieves rotation limit.

[0070] Then, from the loading side of the rotating device 1, i.e. the side away from the side support 13, the carbon beam 2 with its untreated upper surface (the surface on the concave side) is placed on the second rotating member 122, so that the lower surface (the surface on the convex side) of the carbon beam 2 abuts against the second elastic body 1252, and then the upper surface of the carbon beam 2 can be post-processed. Then wait for rotation to facilitate the processing of the lower surface.

[0071] The limiting position on the first rotating component 121 is then released, and the insertion rod 172 is pulled out. The first rotating component 121 is then lowered using the lifting device 14 until the first elastic body 1242 on the first rotating component 121 contacts and abuts against the upper surface of the carbon beam 2. The locking mechanism 123 then locks the other ends of the first rotating component 121 and the second rotating component 122 together. At this point, the first elastic body 1242 and the second elastic body 1252 are clamped from the upper and lower sides of the carbon beam 2. At this point, the workers need to dismantle the hook and remove it.

[0072] Next, multiple servo motors start, driving multiple rotating components 12 to rotate synchronously by 180°, thus swapping the positions of the upper and lower surfaces of the carbon beam 2. Then, the locking mechanism 123 is opened, releasing the other ends of the first rotating component 121 and the second rotating component 122. The lifting device 14 is then connected to the lifting hole 15 on the second rotating component 122, causing the second rotating component 122 to rotate around the hinge axis. At this time, although the lifting device 14 cannot make the opening between the second rotating component 122 and the first rotating component 121 as large as before the rotation, and the limiting mechanism 17 can no longer be used to limit the second rotating component 122, the opening between the second rotating component 122 and the first rotating component 121 is still sufficient for the workers to perform post-processing on the lower surface of the carbon beam 2. At this time, the lifting device 14 is used to limit the rotation position of the second rotating component 122.

[0073] After both surfaces of the carbon beam 2 have been treated, the lifting device 14 lowers the second rotating component 122, and the first rotating component 121 and the second rotating component 122 lock together again, clamping the carbon beam 2. Then, the servo motor starts, driving multiple rotating components 12 to rotate synchronously in opposite directions by 180°. After the first rotating component 121 and the second rotating component 122 are released again, the lifting device 14 drives the first rotating component 121 to rotate, and the limiting mechanism 17 limits the first rotating component 121. Workers can then process the edges of the carbon beam 2. After all processing is completed, the carbon beam 2 can be removed from the loading side and transferred away.

[0074] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
