Description

Technical Field

[0001] This invention relates to the field of wind turbine blade transportation technology, and in particular to a wind turbine blade transportation and carrying device. Background Technology

[0002] Wind power generation is a renewable energy technology that converts wind energy into electricity. The core component of a wind turbine—the wind turbine blade—is typically tens of meters long, and its design and materials determine its wind capture efficiency. Wind turbines are usually installed in areas with abundant and stable wind resources, such as offshore or mountaintops. Due to the enormous size of the blades, existing transportation methods face challenges such as space constraints, wind loads, and complex fixing and support when transporting them to mountaintops. There is an urgent need to improve transportation efficiency and safety, reduce transportation costs, and ensure the blades are not damaged during transport through mechanical structure optimization and technological innovation.

[0003] A wind turbine blade transport device is disclosed in patent publication number CN118622602A, relating to the technical field of wind turbine blade transport. It includes a support unit comprising a mounting base and a slide rail base, the slide rail base being connected to one side of the mounting base; a fixing unit comprising an anti-disengagement hook, an tilting frame, and a buffer seat, the anti-disengagement hook being connected to the mounting base on one side and to the tilting frame on the other side, the buffer seat being disposed opposite to the tilting frame; and an adjustment unit comprising an upper push frame and an auxiliary push frame, the upper push frame and the auxiliary push frame being respectively connected to both ends of the slide rail base, and both having their other ends connected to the tilting frame. This invention solves the problem of existing blade transport trailers where blade vibration during transport easily causes damage to the blades themselves.

[0004] The existing technology has the following drawbacks:

[0005] Insufficient lifting and obstacle avoidance capabilities during transportation: Large wind turbine blades require good lifting and obstacle avoidance capabilities during transportation to cope with complex and changing road conditions, especially when going uphill. If the tail of the blade cannot maintain sufficient height, it is easy to touch the ground or scrape the road surface, causing damage. In addition, the angle of trees and other obstacles in the mountains requires stable lifting of the tail of large wind turbine blades to avoid obstacles. Therefore, it is necessary to set up a mechanism to stably lift the tail of large wind turbine blades to improve the lifting and obstacle avoidance capabilities of large wind turbine blades during transportation, ensure the blades are safe and undamaged during transportation, and achieve the effect of improving transportation efficiency and reliability.

[0006] Insufficient adjustment capability between clamping support and wind load factors during transportation: Blades may sway or tilt significantly under wind force, affecting stability. If the clamping device cannot effectively cope with changes in wind load, it may loosen or be damaged. However, if the clamping is too tight, the support structure will bear excessive additional load in strong winds, which may lead to deformation or breakage. Therefore, it is necessary to set up a more stable and adjustable clamping device to ensure that it can adapt to different wind load conditions, improve the fixing effect, and achieve the effect of improving the adjustment capability and safety during transportation. Summary of the Invention

[0007] In view of the problems of insufficient lifting and obstacle avoidance capabilities during transportation and insufficient adjustment capabilities between clamping support and wind load factors in existing technologies, a wind turbine blade transportation and support device is proposed.

[0008] This application provides a wind turbine blade transport carrying device, the purpose of which is to improve the lifting and obstacle avoidance capability of large wind turbine blades during transport by setting up lifting components, clamping components and auxiliary support mechanisms, ensuring the blades are safe and undamaged during transport, thereby improving transport efficiency and reliability. By setting up support components and limiting components, it ensures that it can adapt to different wind load conditions, improves the fixing effect, and improves the adjustability and safety during transport.

[0009] The technical solution of the present invention is as follows: a wind turbine blade transport and support device, comprising a carrier vehicle, a clamping and lifting mechanism installed above the carrier vehicle, an auxiliary vehicle located behind the carrier vehicle, an auxiliary support mechanism installed above the auxiliary vehicle, and a wind turbine blade disposed between the clamping and lifting mechanism and the auxiliary support mechanism. The clamping and lifting mechanism includes a fixed frame fixedly installed above the carrier vehicle, and a lifting component and a support component are fixedly installed on the top of the fixed frame. The auxiliary support mechanism includes a limiting component disposed on the outer wall of the wind turbine blade, and the limiting component includes a limiting frame disposed between the wind turbine blade and the auxiliary vehicle.

[0010] The lifting assembly includes a servo motor and a shaped support frame fixedly connected to the top of the fixed frame. The output shaft of the servo motor is fitted with a winding wheel, and a steel wire rope is wound around the surface of the winding wheel. The two ends of the steel wire rope pass through the upper and lower ends of the shaped support frame and extend towards the direction of the wind turbine blades. A swing ball is fixedly installed on the inner wall of the shaped support frame, and a swing assembly is movably connected to the outer wall of the swing ball.

[0011] Using the above scheme, when the wind turbine blades need to be lifted for obstacle avoidance, the servo motor is activated by the lifting component. The output shaft of the servo motor drives the winding wheel to rotate, causing the wire rope to loop on the winding wheel. At this time, the upper wire rope pulls the swing component through the irregular support frame, while the lower wire rope is relaxed, causing the wind turbine blades to be lifted around the swing ball as the axis, thus lifting the wind turbine blades.

[0012] Furthermore, the swing assembly includes a swing frame disposed between the irregular support frame and the wind turbine blade. Both ends of the swing frame are provided with locking rope holes. The two ends of the steel wire rope pass through the two locking rope holes respectively and are hinged to the outside of the swing frame. A swing groove is provided on the side surface of the swing frame near the irregular support frame. The inner wall of the swing groove is movably connected to the outer wall of the swing ball. Multiple evenly distributed sliding frames are fixedly connected to the outer wall of the swing frame. Clamping components are slidably connected to the outer walls of the multiple sliding frames.

[0013] Using the above scheme, through the set swing component, the upper steel wire rope pulls the swing frame closer to the irregular support frame by passing through the irregular support frame and the upper locking rope hole, and the lower steel wire rope pulls the swing frame away from the irregular support frame by passing through the irregular support frame and the lower locking rope hole, so that the wind turbine blades are raised. And through the swing groove, it is movably connected to the swing ball. When the wind turbine blades swing, the wind turbine blades are not locked, avoiding damage to the wind turbine blades caused by the swing.

[0014] Furthermore, the clamping assembly includes two flexible pads overlapping the inner and outer sides of the wind turbine blade. An inner clamping plate and an outer clamping plate are respectively hinged to the side of the two flexible pads away from the wind turbine blade. The inner walls of the inner and outer clamping plates are provided with sliding grooves. The inner walls of the sliding grooves are slidably connected to the outer wall of the sliding frame. Locking bolts are hinged between the inner and outer clamping plates.

[0015] Using the above scheme, a suitable flexible pad is placed on the inner and outer sides of the wind turbine blade head through the clamping assembly. Then, the inner and outer clamping plates are operated on the sliding frame to clamp the wind turbine blade head and lock it with locking bolts to achieve stable clamping.

[0016] Furthermore, the auxiliary support mechanism also includes a connecting plate fixedly installed at the bottom of the limiting frame, a turntable rotatably connected to the bottom of the connecting plate, and a rotation shaft rotatably connected to the bottom of the turntable.

[0017] Furthermore, a steering device is fixedly connected to the top of the auxiliary vehicle, and a telescopic hydraulic rod is fixedly connected to the output shaft of the steering device. The end of the telescopic hydraulic rod near the connecting plate is fixedly connected to the rotation shaft.

[0018] By adopting the above scheme, the steering device and telescopic hydraulic rod operate synchronously with the wind turbine blades as they are lifted through the auxiliary support mechanism. The steering device is responsible for steering the telescopic hydraulic rod, which extends and supports the lifting limit frame by abutting the turntable via its rotation shaft. When the vehicle is turning, the turntable can rotate at the connecting plate, making steering more convenient. This improves the lifting and obstacle avoidance capability of large wind turbine blades during transportation, ensuring the blades are safe and undamaged during transportation, and achieving the effect of improving transportation efficiency and reliability.

[0019] Furthermore, the support assembly includes a support spring fixedly installed on the top of the mounting frame, a support plate fixedly connected to the top of the support spring, and multiple arc-shaped support pads provided between the support plate and the wind turbine blades.

[0020] Furthermore, a movable hinge is fixedly connected to the top of the support plate, and the movable hinge is installed between two adjacent arc-shaped support pads. A lifting bolt is threaded inside the support plate, and the top of the lifting bolt is rotatably connected to the bottom of the corresponding edge arc-shaped support pad.

[0021] By adopting the above solution, the support components are designed so that when the wind turbine blades sway in strong winds or on bumpy roads, the arc-shaped support pads fixed to the bottom of the wind turbine blades by the lifting bolts, and the support springs between the support plate and the fixed frame, can provide shock absorption. This ensures that it can adapt to different wind load conditions, improves the fixing effect, and achieves the effect of improving the adjustability and safety during transportation.

[0022] Furthermore, the limiting component also includes multiple flexible ropes fixedly installed on the outer wall of the wind turbine blade, and multiple flexible pull ropes are fixedly connected to the outer wall of each of the multiple flexible ropes. The ends of the multiple flexible pull ropes away from the wind turbine blade are hinged to the outer wall of the limiting frame.

[0023] Using the above solution, the limiting frame is installed at the center of gravity of the wind turbine blade through the setting limiting components. A flexible rope is used to loop around the outer wall of the wind turbine blade and tighten it to fit. Then, a flexible pull rope is used to fix the flexible rope in the middle of the limiting frame. Both the flexible pull rope and the flexible rope are elastic and can provide a certain amount of tension and shock absorption when the wind turbine blade sways.

[0024] The beneficial effects of this invention are:

[0025] 1. Through the set lifting and support components, when the wind turbine blades need to be lifted for obstacle avoidance, the servo motor is activated. The output shaft of the servo motor drives the winding wheel to rotate, causing the wire rope to loop on the winding wheel. At this time, the upper wire rope pulls the swing component through the irregular support frame, while the lower wire rope is released, causing the wind turbine blade to be lifted around the swing ball as the axis. At the same time, the steering device and the telescopic hydraulic rod operate synchronously. The steering device is responsible for steering the telescopic hydraulic rod. The telescopic hydraulic rod extends and supports the lifting limit frame by abutting the turntable through the rotation shaft. When the vehicle is turning, the turntable can rotate at the connecting plate, making steering more convenient. This improves the lifting and obstacle avoidance capability of large wind turbine blades during transportation, ensures the blades are safe and undamaged during transportation, and achieves the effect of improving transportation efficiency and reliability.

[0026] 2. With the support and limiting components in place, when encountering strong winds or bumpy roads, the wind turbine blades will sway. The flexible pull rope and flexible sling can provide a certain amount of tension and shock absorption. At the same time, the arc-shaped support pads that fit into the bottom of the wind turbine blades through the lifting bolts and the support springs between the support plate and the fixed frame can also provide shock absorption. This ensures that it can adapt to different wind load conditions, improves the fixing effect, and achieves the effect of improving the adjustability and safety during transportation.

[0027] 3. By using the swing assembly and clamping assembly, a suitable flexible pad is placed on the inner and outer sides of the wind turbine blade head. Then, the inner and outer clamping plates are operated on the sliding frame to clamp the wind turbine blade head and lock it with locking bolts. The flexible pad changes according to the different diameters of the wind turbine blade head. At the same time, the inner and outer clamping plates slide on the sliding frame through the sliding groove, which can adapt to wind turbine blades of different sizes. Attached Figure Description

[0042] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Example 1, referring to Figure 1 - Figure 8The first embodiment of the present invention provides a wind turbine blade transport and support device, including a carrier vehicle 1, a clamping and lifting mechanism 2 installed above the carrier vehicle 1, an auxiliary vehicle 5 located behind the carrier vehicle 1, an auxiliary support mechanism 4 installed above the auxiliary vehicle 5, and a wind turbine blade 3 disposed between the clamping and lifting mechanism 2 and the auxiliary support mechanism 4. The clamping and lifting mechanism 2 includes a fixed frame 21 fixedly installed above the carrier vehicle 1, and a lifting component 22 and a support component 25 fixedly installed on the top of the fixed frame 21. The auxiliary support mechanism 4 includes a limiting component 41 disposed on the outer wall of the wind turbine blade 3, and the limiting component 41 includes a limiting frame 411 disposed between the wind turbine blade 3 and the auxiliary vehicle 5.

[0044] Reference Figure 4 The lifting assembly 22 includes a servo motor 221 and a shaped support frame 224 fixedly connected to the top of the fixed frame 21. The output shaft of the servo motor 221 is fitted with a winding wheel 222. A steel wire rope 223 is wound around the surface of the winding wheel 222. The two ends of the steel wire rope 223 pass through the upper and lower ends of the shaped support frame 224 and extend towards the wind turbine blade 3. A swing ball 225 is fixedly installed on the inner wall of the shaped support frame 224. A swing assembly 23 is movably connected to the outer wall of the swing ball 225.

[0045] Specifically, both the carrier vehicle 1 and the auxiliary vehicle 5 are multi-axle flatbed trucks. The carrier vehicle 1 plays the role of traction, carrying, clamping and steering, while the auxiliary vehicle 5 plays the role of carrying, supporting and steering. The clamping and lifting mechanism 2 is used for clamping, lifting and supporting the head of the wind turbine blade 3, and the auxiliary support mechanism 4 is used for clamping, lifting and supporting the center of gravity of the wind turbine blade 3. The lifting component 22 is powered by the servo motor 221 to pull the wire rope 223 on the winding wheel 222, and the swing component 23 swings through the swing ball 225.

[0046] When the wind turbine blade 3 needs to be lifted for obstacle avoidance, the servo motor 221 is activated by the lifting component 22. The output shaft of the servo motor 221 drives the winding wheel 222 to rotate, causing the wire rope 223 to wrap around the winding wheel 222. At this time, the upper wire rope 223 pulls the swing component 23 through the irregular support frame 224, while the lower wire rope 223 is relaxed, causing the wind turbine blade 3 to be lifted around the swing ball 225 as the axis, thus lifting the wind turbine blade 3.

[0047] Reference Figure 5 - Figure 6The swing assembly 23 includes a swing frame 231 disposed between the irregular support frame 224 and the wind turbine blade 3. Both the upper and lower ends of the swing frame 231 are provided with rope locking holes 232. The two ends of the steel wire rope 223 pass through the two rope locking holes 232 respectively and are hinged to the outside of the swing frame 231. A swing groove 233 is provided on the side surface of the swing frame 231 near the irregular support frame 224. The inner wall of the swing groove 233 is movably connected to the outer wall of the swing ball 225. A plurality of evenly distributed sliding frames 234 are fixedly connected to the outer wall of the swing frame 231. Clamping assemblies 24 are slidably connected to the outer walls of the plurality of sliding frames 234.

[0048] The swing assembly 23 is configured such that the upper wire rope 223 pulls the swing frame 231 closer to the irregular support frame 224 through the irregular support frame 224 and the upper locking rope hole 232, while the lower wire rope 223 pulls the swing frame 231 away from the irregular support frame 224 through the irregular support frame 224 and the lower locking rope hole 232, thereby raising the wind turbine blade 3. The swing assembly 223 is movably connected to the swing ball 225 through the swing groove 233. When the wind turbine blade 3 swings, it can prevent the wind turbine blade 3 from being locked, thus avoiding damage to the wind turbine blade 3 caused by the swing.

[0049] Reference Figure 6 The clamping assembly 24 includes two flexible pads 244 that overlap the inner and outer sides of the wind turbine blade 3. The two flexible pads 244 are respectively hinged to an inner clamping plate 241 and an outer clamping plate 242 on the side away from the wind turbine blade 3. The inner walls of the inner clamping plate 241 and the outer clamping plate 242 are provided with sliding grooves 243. The inner wall of the sliding groove 243 is slidably connected to the outer wall of the sliding frame 234. A locking bolt 245 is hinged between the inner clamping plate 241 and the outer clamping plate 242.

[0050] Specifically, the flexible pad 244 changes according to the head of the wind turbine blade 3 of different diameters, so that the clamping assembly 24 can fit the wind turbine blade 3 of different sizes. At the same time, the inner clamping plate 241 and the outer clamping plate 242 slide on the sliding frame 234 through the sliding groove 243, which can also be adapted to wind turbine blades 3 of different sizes.

[0051] By using the clamping assembly 24, a suitable flexible pad 244 is placed on the inner and outer sides of the head of the wind turbine blade 3. Then, the inner clamping plate 241 and the outer clamping plate 242 are operated on the sliding frame 234 to clamp the head of the wind turbine blade 3. The locking bolt 245 is used to lock it, which plays a role in stabilizing the clamping.

[0052] Reference Figure 7 - Figure 8The auxiliary support mechanism 4 also includes a connecting plate 42 fixedly installed at the bottom of the limit frame 411. A turntable 43 is rotatably connected to the bottom of the connecting plate 42, and a rotation shaft 44 is rotatably connected to the bottom of the turntable 43. A steering device 46 is fixedly connected above the auxiliary vehicle 5. A telescopic hydraulic rod 45 is fixedly connected to the output shaft of the steering device 46. One end of the telescopic hydraulic rod 45 near the connecting plate 42 is fixedly connected to the rotation shaft 44.

[0053] With the auxiliary support mechanism 4 in place, the wind turbine blade 3 is lifted while the steering device 46 and the telescopic hydraulic rod 45 operate synchronously. The steering device 46 is responsible for steering the telescopic hydraulic rod 45. The telescopic hydraulic rod 45 extends and supports the lifting limit frame 411 by abutting the turntable 43 through the self-rotating shaft 44. When the carrying vehicle 1 turns, the turntable 43 can rotate at the connecting plate 42, making steering more convenient. This improves the lifting and obstacle avoidance capability of large wind turbine blades during transportation, ensures the blades are safe and undamaged during transportation, and achieves the effect of improving transportation efficiency and reliability.

[0054] During use, a crane is used to hoist the wind turbine blade 3 along with the limiting frame 411 onto the carrier vehicle 1 and the auxiliary vehicle 5. A suitable flexible pad 244 is placed on the inner and outer sides of the wind turbine blade 3 head. Then, the inner clamping plate 241 and outer clamping plate 242 are operated on the sliding frame 234 to clamp the head of the wind turbine blade 3 and lock it with locking bolts 245. Simultaneously, the limiting frame 411 is installed on the connecting plate 42, completing the loading. When the wind turbine blade 3 needs to be lifted for obstacle avoidance, the servo motor 221 is activated. The output shaft of the servo motor 221 drives the winding wheel 222 to rotate, causing the wire rope 223 to wind around the winding wheel 222. At this time, the upper wire rope 223 passes through the irregular support frame 224 and the upper... The square locking rope hole 232 pulls the swing frame 231 closer to the irregular support frame 224, while the lower wire rope 223 is loosened, causing the wind turbine blade 3 to be lifted around the swing ball 225 as the axis. At the same time as the wind turbine blade 3 is lifted, the steering device 46 and the telescopic hydraulic rod 45 operate synchronously. The steering device 46 is responsible for steering the telescopic hydraulic rod 45. The telescopic hydraulic rod 45 extends and supports the lifting limit frame 411 by abutting the turntable 43 through the self-rotating shaft 44. When the carrying vehicle 1 turns, the turntable 43 can rotate at the connecting plate 42, making the turning more convenient. This improves the lifting and obstacle avoidance ability of large wind turbine blades during transportation, ensures the blades are safe and undamaged during transportation, and achieves the effect of improving transportation efficiency and reliability.

[0055] Example 2, refer to Figure 9 - Figure 12 This is the second embodiment of the present invention, which differs from the first embodiment in that: referring to Figure 9The support assembly 25 includes a support spring 252 fixedly installed on the top of the fixed frame 21. A support plate 251 is fixedly connected to the top of the support spring 252. Multiple arc-shaped support pads 254 are provided between the support plate 251 and the wind turbine blade 3. A movable hinge 253 is fixedly connected to the top of the support plate 251. The movable hinge 253 is installed between two adjacent arc-shaped support pads 254. A lifting bolt 255 is threaded inside the support plate 251. The top of the lifting bolt 255 is rotatably connected to the bottom of the corresponding edge arc-shaped support pad 254.

[0056] Specifically, the movable hinge 253 is set between two adjacent arc-shaped support pads 254, so that multiple arc-shaped support pads 254 are connected into a whole. Under the adjustment of the lifting bolt 255, it can rotate according to the head diameter of the wind turbine blade 3 of different sizes, so that the arc-shaped support pad 254 fits against the outer wall of the wind turbine blade 3.

[0057] With the support component 25 in place, when encountering strong winds or bumpy road sections, the wind turbine blades 3 will shake. The arc-shaped support pad 254, which is fixed to the bottom of the wind turbine blades 3 by the lifting bolts 255, and the support spring 252 between the support plate 251 and the fixed frame 21, can provide shock absorption. This ensures that it can adapt to different wind load conditions, improves the fixing effect, and achieves the effect of improving the adjustability and safety during transportation.

[0058] Reference Figure 10 The limiting component 41 also includes multiple flexible ropes 413 fixedly installed on the outer wall of the wind turbine blade 3. Multiple flexible pull ropes 412 are fixedly connected to the outer wall of each flexible rope 413. The ends of the multiple flexible pull ropes 412 away from the wind turbine blade 3 are all hinged to the outer wall of the limiting frame 411.

[0059] Specifically, the flexible loop 413 fits the outer wall of the wind turbine blade 3 at different positions, and the flexible pull rope 412 pulls the flexible loop 413 in a cross shape. Both the flexible loop 413 and the flexible pull rope 412 have a certain degree of elasticity.

[0060] By using the limiting component 41, the limiting frame 411 is installed at the center of gravity of the wind turbine blade 3. A flexible rope 413 is used to loop around the outer wall of the wind turbine blade 3 and tighten it to fit. Then, a flexible pull rope 412 is used to fix the flexible rope 413 in the middle of the limiting frame 411. Both the flexible pull rope 412 and the flexible rope 413 are elastic and can provide a certain amount of tension and shock absorption when the wind turbine blade 3 sways.

[0061] During use, the limiting frame 411 is first installed at the center of gravity of the wind turbine blade 3. A flexible rope 413 is then looped around the outer wall of the wind turbine blade 3 and pulled taut. A flexible pull rope 412 is then used to fix the flexible rope 413 in the middle of the limiting frame 411 before loading. When encountering strong winds or bumpy roads, the wind turbine blade 3 will sway. In addition to the pulling and shock absorption of the flexible pull rope 412 and the flexible rope 413, the arc-shaped support pad 254 fixed to the bottom of the wind turbine blade 3 by the lifting bolt 255, and the support spring 252 between the support plate 251 and the fixing frame 21, all provide shock absorption. This ensures adaptability to different wind load conditions, improves the fixing effect, and enhances the adjustability and safety during transportation. The remaining structure is the same as in Example 1.

[0062] Working principle of the invention:

[0063] Before loading, the limiting frame 411 is installed at the center of gravity of the wind turbine blade 3. The flexible rope 413 is then looped around the outer wall of the wind turbine blade 3 and pulled tight. The flexible rope 412 is then used to fix the flexible rope 413 in the middle of the limiting frame 411. Both the flexible rope 412 and the flexible rope 413 are elastic and can provide a certain amount of tension and shock absorption when the wind turbine blade 3 sways.

[0064] During loading, a crane is used to hoist the wind turbine blade 3 along with the limiting frame 411 onto the carrier vehicle 1 and the auxiliary vehicle 5. A suitable flexible pad 244 is placed on the inner and outer sides of the head of the wind turbine blade 3. Then, the inner clamping plate 241 and the outer clamping plate 242 are operated on the sliding frame 234 to clamp the head of the wind turbine blade 3 and lock it with the locking bolt 245. At the same time, the limiting frame 411 is installed on the connecting plate 42 to complete the loading.

[0065] When the wind turbine blade 3 needs to be raised for obstacle avoidance, the servo motor 221 is activated. The output shaft of the servo motor 221 drives the winding wheel 222 to rotate, causing the wire rope 223 to wrap around the winding wheel 222. At this time, the upper wire rope 223 pulls the swing frame 231 close to the irregular support frame 224 through the irregular support frame 224 and the upper locking hole 232, while the lower wire rope 223 is relaxed, causing the wind turbine blade 3 to be raised around the swing ball 225 as the axis.

[0066] As the wind turbine blade 3 is lifted, the steering device 46 and the telescopic hydraulic rod 45 operate synchronously. The steering device 46 is responsible for steering the telescopic hydraulic rod 45. The telescopic hydraulic rod 45 extends and supports the lifting limit frame 411 by abutting the turntable 43 through the self-rotating shaft 44. When the carrying vehicle 1 turns, the turntable 43 can rotate at the connecting plate 42, making steering more convenient. This improves the lifting and obstacle avoidance capability of large wind turbine blades during transportation, ensures the blades are safe and undamaged during transportation, and achieves the effect of improving transportation efficiency and reliability.

[0067] When encountering strong winds or bumpy road sections, the wind turbine blades 3 sway. In addition to the pulling and shock absorption of the flexible ropes 412 and flexible loops 413, the arc-shaped support pads 254 fixed to the bottom of the wind turbine blades 3 by the lifting bolts 255 and the support springs 252 between the support plate 251 and the fixed frame 21 can also provide shock absorption. This ensures that it can adapt to different wind load conditions, improves the fixing effect, and achieves the effect of improving the adjustability and safety during transportation.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
