Description

Technical Field

[0001] This utility model belongs to the field of wind turbine blade transportation technology, and specifically relates to an adaptive curved surface clamping bracket for wind turbine blade transportation and fixing. Background Technology

[0002] During the transportation of wind turbine blades, due to their large size, uneven weight distribution, and susceptibility to wind loads and road bumps, they are prone to bending, vibration, or collisions. To ensure the absolute safety of these high-value, fragile critical components during long-distance land or sea transport and to prevent damage such as twisting, breakage, and surface scratches, specially designed and manufactured clamping brackets must be used to precisely fix them.

[0003] To meet aerodynamic performance requirements, wind turbine blades are often designed with complex curved surfaces. However, traditional transport clamping supports mostly employ rigid, fixed-geometry clamping structures. This inherent design flaw prevents the clamping ends from precisely conforming to the varying curvature changes across the blade, resulting in severely uneven clamping force distribution and significantly reduced clamping stability. Especially under the influence of road bumps, wind loads, and the enormous inertial forces generated by vehicle acceleration and deceleration, unrestrained blades are highly susceptible to significant displacement, violent shaking, and even hard collisions with the support or transport vehicle, ultimately leading to blade damage. Utility Model Content

[0004] To address the problem that the clamping end cannot accurately conform to the varying curvature changes of different parts of the blade, this utility model proposes an adaptive curved surface clamping bracket for wind turbine blade transportation and fixing, in order to overcome the aforementioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an adaptive curved surface clamping bracket for transporting and fixing wind turbine blades, including a support frame. Both sides of the support frame are provided with elastic clamping components and driving components. The driving components are poweredly connected to the elastic clamping components. The elastic clamping components are provided with a plurality of clamping ends. The outer side of the support frame is provided with a limit component. The limit component is provided with a plurality of limit ends corresponding to the clamping ends. The support frame is used to support the wind turbine blade, the drive assembly is used to drive the elastic clamping assembly so that a plurality of clamping ends on the elastic clamping assembly come into contact with the surface of the wind turbine blade, and the limiting assembly is used to limit the clamping ends.

[0006] Furthermore, the elastic clamping assembly includes a push plate, which is disposed on the outside of the support frame. A plurality of moving slots are arrayed on the outside of the push plate. A clamping rod is movably connected inside the moving slot. A connecting plate is fixedly connected to one end of the clamping rod. A push spring is fixedly connected between the connecting plate and the push plate.

[0007] Furthermore, the drive assembly includes an L-shaped mounting plate, multiple L-shaped mounting plates are fixedly mounted on the outside of the support frame, a drive screw is rotatably connected between the L-shaped mounting plates and the support frame, the push plate is threadedly connected to the drive screw, and a sprocket is fixedly connected to the outer surface of each of the drive screws, and a chain is engaged on the outer surface of the sprocket.

[0008] Furthermore, a storage box is fixedly installed on the inner side of the L-shaped mounting plate, and the sprocket and chain are both located inside the storage box. One end of one of the drive screws extends to the outside of the L-shaped mounting plate and is fixedly connected to a control ring.

[0009] Furthermore, the limiting component includes an L-shaped limiting plate, which is disposed on the outside of the support frame. The outside of the L-shaped limiting plate is provided with a plurality of limiting grooves corresponding to the clamping rod. The clamping rod is movably connected to the limiting grooves. Friction grooves are provided on the top of the clamping rod and the top of the inner wall of the limiting groove.

[0010] Furthermore, a lifting screw is threadedly connected to the top of the support frame, the bottom end of the lifting screw passes through the support frame and is rotatably connected to the L-shaped limiting plate, a guide rod is fixedly connected to the top of the L-shaped limiting plate, the guide rod is movably connected to the support frame, and a control panel is fixedly connected to the top of the lifting screw.

[0011] Furthermore, the inner wall of the support frame is provided with a lifting groove, and a T-shaped limiting rod is movably connected inside the lifting groove. One end of the T-shaped limiting rod is fixedly connected to an L-shaped limiting plate.

[0012] This utility model has the following beneficial effects: 1. This utility model drives the elastic clamping component through a driving component. Simultaneously, because the elastic end can push the clamping end, after one clamping end contacts the wind turbine blade, the elastic clamping component can move normally, ensuring that all clamping ends contact the surface of the wind turbine blade. This configuration allows the clamping ends to precisely match the complex and varied curvature of the wind turbine blade, achieving a tight fit. Furthermore, the upper limit component can limit the position of the clamping ends, thereby improving the stability of the clamping and fixing of the wind turbine blade. It also effectively prevents damage to the wind turbine blade due to hard collisions with the support frame or transport vehicle during transportation.

[0013] 2. This utility model uses a control panel to rotate the lifting screw. The rotating lifting screw moves downwards towards the L-shaped limiting plate, and several limiting grooves come into contact with the corresponding clamping rods. At this time, with the assistance of the friction grooves, the friction between the limiting grooves and the clamping rods is large. Combined with the point-to-point precise limiting design, the displacement freedom of several clamping rods is effectively restricted. The above-mentioned settings, through the dual guarantee of enhanced contact friction and precise limiting, greatly improve the fixing strength of several clamping rods to the wind turbine blades, ensuring that the blades remain stable during transportation and avoiding potential risks caused by loosening and displacement.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0020] Please see Figures 1-6 As shown, this utility model is an adaptive curved surface clamping bracket for transporting and fixing wind turbine blades, including a support frame 1. Both sides of the support frame 1 are provided with elastic clamping components 2 and driving components 3. The driving components 3 are poweredly connected to the elastic clamping components 2. The elastic clamping components 2 are provided with a plurality of clamping ends. The outer side of the support frame 1 is provided with a limiting component 4. The limiting end of the limiting component 4 is provided with a plurality of limiting ends corresponding to the clamping ends. The support frame 1 is used to support the wind turbine blade, the drive component 3 is used to drive the elastic clamping component 2 so that a plurality of clamping ends on the elastic clamping component 2 come into contact with the surface of the wind turbine blade, and the limiting component 4 is used to limit the clamping ends.

[0021] The wind turbine blade is placed inside the support frame 1 by the hoisting device. Then, the two elastic clamping components 2 are driven by the drive components 3 on both sides of the support frame 1. This causes several clamping ends on the elastic clamping components 2 to come into contact with the surface of the wind turbine blade one after another under the push of the elastic ends, directly driving the limiting component 4. This allows the limiting component 4 to squeeze and limit several clamping ends.

[0022] The elastic clamping component 2 is driven by the driving component 3. Since the elastic end can push the clamping end, the elastic clamping component 2 can move normally after one of the clamping ends comes into contact with the wind turbine blade, so that all the clamping ends come into contact with the surface of the wind turbine blade. The above configuration allows the clamping ends to accurately match the complex and varied curvature of the wind turbine blade and achieve a tight fit. In addition, the upper limit component 4 can limit the position of the clamping ends, thereby improving the stability of the clamping ends in clamping and fixing the wind turbine blade. At the same time, it effectively avoids damage to the wind turbine blade due to hard collision with the support frame 1 or the transport vehicle during transportation.

[0023] In one embodiment, the elastic clamping assembly 2 includes a push plate 201, which is disposed on the outside of the support frame 1. The outer side of the push plate 201 has a plurality of moving slots 202 arranged in an array. A clamping rod 203 is movably connected inside the moving slot 202. One end of the clamping rod 203 is fixedly connected to a connecting plate 204. A push spring 205 is fixedly connected between the connecting plate 204 and the push plate 201.

[0024] By pushing the push plate 201, the push plate 201 drives the clamping rod 203 to move through the connecting plate 204 and the push spring 205. At this time, the clamping rod 203 can continuously move into the support frame 1 through the moving groove 202 opened on the support frame 1. When one of the clamping rods 203 contacts the wind turbine blade, the push plate 201 continues to move, while the clamping rods 203 that cannot move can move inside the moving groove 202 opened on the push plate 201 and pull the push spring 205 backward. With the above settings, only the push plate 201 needs to be moved to make all the clamping rods 203 contact the surface of the wind turbine blade. At the same time, the push spring 205 ensures that the clamping rods 203 and the wind turbine blade can always maintain a tight contact after they come into contact.

[0025] In one embodiment, the drive assembly 3 includes an L-shaped mounting plate 301. Multiple L-shaped mounting plates 301 are fixedly mounted on the outside of the support frame 1. A drive screw 302 is rotatably connected between the L-shaped mounting plates 301 and the support frame 1. The push plate 201 is threadedly connected to the drive screw 302. A sprocket 303 is fixedly connected to the outer surface of each of the drive screws 302. A chain 304 is engaged on the outer surface of the sprocket 303.

[0026] The push plate 201 moves under the drive of multiple drive screws 302 by rotating one of the drive screws 302. The rotation of the drive screw 302 drives all the drive screws 302 to rotate synchronously through the sprocket 303 and the chain 304. The arrangement of multiple drive screws 302 makes the push plate 201 push the several clamping rods 203 more smoothly. At the same time, only one drive screw 302 needs to be rotated to make all the drive screws 302 on one side of the support frame 1 rotate synchronously, which is also more convenient to operate.

[0027] In one embodiment, for the L-shaped mounting plate 301, a storage box 305 is fixedly installed on the inner side of the L-shaped mounting plate 301, and the sprocket 303 and chain 304 are both disposed inside the storage box 305. One end of one of the drive screws 302 extends to the outside of the L-shaped mounting plate 301 and is fixedly connected to a control ring 306.

[0028] The drive screw 302 can be rotated relatively easily through the control ring 306; the storage box 305 can shield the sprocket 303 and chain 304, so that external dust and impurities will not accumulate on the sprocket 303 and chain 304 when transporting wind turbine blades.

[0029] In one embodiment, the limiting component 4 includes an L-shaped limiting plate 401, which is disposed on the outside of the support frame 1. The outer side of the L-shaped limiting plate 401 is provided with a plurality of limiting grooves 402 corresponding to the clamping rod 203. The clamping rod 203 is movably connected to the limiting grooves 402. The top of the clamping rod 203 and the top of the inner wall of the limiting groove 402 are both provided with friction grooves 403.

[0030] Once all the clamping rods 203 are in contact with the wind turbine blade, the L-shaped limiting plate 401 is pushed downwards, allowing the top of the inner wall of the limiting groove 402 on the L-shaped limiting plate 401 to contact the top of the corresponding clamping rod 203. At this time, with the assistance of the friction groove 403, the friction between the limiting groove 402 and the clamping rod 203 is large, thus preventing the clamping rod 203 from moving arbitrarily. This also ensures the firmness of the clamping rod 203 when clamping and fixing the wind turbine blade.

[0031] In one embodiment, for the support frame 1, the top of the support frame 1 is threadedly connected to a lifting screw 404, the bottom end of the lifting screw 404 passes through the support frame 1 and is rotatably connected to an L-shaped limiting plate 401, the top of the L-shaped limiting plate 401 is fixedly connected to a guide rod 405, the guide rod 405 is movably connected to the support frame 1, and the top end of the lifting screw 404 is fixedly connected to a control panel 406.

[0032] The lifting screw 404 is rotated by the control panel 406. The rotating lifting screw 404 can move downward. At this time, the L-shaped limiting plate 401 moves under the push of the lifting screw 404 and the guidance of the guide rod 405, so that the limiting groove 402 can contact the clamping rod 203. In the above setting, since the lifting screw 404 has a self-locking function, the L-shaped limiting plate 401 will not move arbitrarily after the limiting groove 402 contacts the clamping rod 203.

[0033] In one embodiment, for the support frame 1, the inner wall of the support frame 1 is provided with a lifting groove 407, and a T-shaped limiting rod 408 is movably connected inside the lifting groove 407. One end of the T-shaped limiting rod 408 is fixedly connected to an L-shaped limiting plate 401.

[0034] When the L-shaped limiting plate 401 moves, it can drive the T-shaped limiting rod 408 to move inside the lifting groove 407. Under the restriction of the T-shaped limiting rod 408, the L-shaped limiting plate 401 can fit tightly against the outside of the support frame 1. This setting further improves the effect of the limiting groove 402 on the L-shaped limiting plate 401 in limiting the clamping rod 203.

[0035] Through the above technical solution, 1. The driving component 3 drives the elastic clamping component 2. Simultaneously, because the elastic end can push the clamping end, after one clamping end contacts the wind turbine blade, the elastic clamping component 2 can move normally, ensuring that all clamping ends contact the surface of the wind turbine blade. This arrangement allows the clamping ends to precisely match the complex and varied curvature of the wind turbine blade, achieving a tight fit. Furthermore, the upper limit component 4 can limit the position of the clamping ends, thereby improving the stability of the clamping and fixing of the wind turbine blade. It also effectively prevents the wind turbine blade from slipping due to contact with the support frame during transportation. 1. Damage occurs due to a hard collision with the transport vehicle; 2. The lifting screw 404 is rotated via the control panel 406. The rotating lifting screw 404 moves downwards towards the L-shaped limiting plate 401, and several limiting grooves 402 come into contact with the corresponding clamping rods 203. At this time, with the assistance of the friction grooves 403, the friction between the limiting grooves 402 and the clamping rods 203 is large. Combined with the point-to-point precise limiting design, the displacement freedom of several clamping rods 203 is effectively restricted. The above settings, through the dual guarantee of enhanced contact friction and precise limiting, greatly improve the fixing strength of several clamping rods 203 to the wind turbine blade, ensuring that the blade remains stable during transportation and avoiding potential risks caused by loosening and displacement.
