Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation blade transportation, and in particular to a wind power generation blade transportation bearing device. Background Art

[0002] Wind power generation is a renewable energy technology that converts wind energy into electrical energy. The core component of a wind turbine, the wind turbine blade, is usually tens of meters long. Its design and materials determine its wind capture efficiency. Wind turbines are often installed in areas with abundant and stable wind resources, such as at sea or on top of a mountain. Due to the huge size of the blades, when transporting them to the top of the mountain, existing transportation devices face challenges such as space limitations, wind load influence, and complex fixing and support. There is an urgent need to improve transportation efficiency and safety, reduce transportation costs, and ensure that the blades are not damaged during transportation through mechanical structure optimization and technological innovation.

[0003] A wind power generation blade transportation device is disclosed in the patent with patent publication number CN118622602A, which relates to the technical field of wind turbine blade transportation; it includes a supporting unit, including a mounting seat and a slide rail seat, the slide rail seat is connected to one side of the mounting seat; a fixing unit, including an anti-detachment hook, a tilting frame and a buffer seat, one side of the anti-detachment hook is connected to the mounting seat, and the other side is connected to the tilting frame, the buffer seat is relatively arranged on the tilting frame, and; an adjusting unit, including an upper push frame and an auxiliary push frame, the upper push frame and the auxiliary push frame are respectively connected to the two ends of the slide rail seat, and the other ends of the two are also connected to the tilting frame. The present invention solves the problem of the existing blade transportation trailer that the vibration of the blades during transportation is easy to cause self-damage.

[0004] The prior art has the following defects:

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

[0006] Insufficient adjustment ability between the clamping support and wind load factors during transportation: the blades will shake or tilt significantly under the action of wind, affecting stability. If the clamping device cannot effectively cope with the changes in wind load, it will cause loosening or damage. However, if the clamping is too tight, the supporting structure will bear too much additional load in strong winds, which will cause deformation or breakage. Therefore, a more stable and adjustable clamping device is needed to ensure that it can adapt to different wind load conditions, improve the fixing effect, and achieve the effect of improving the adjustment ability and safety during transportation. Summary of the invention

[0007] In view of the problems in the prior art such as insufficient lifting and obstacle avoidance capability during transportation and insufficient adjustment capability between clamping support and wind load factors during transportation, a wind turbine blade transportation and carrying device is proposed.

[0008] The present application provides a wind turbine blade transport and carrying device, the purpose of which is to improve the lifting and obstacle avoidance capabilities of large wind turbine blades during transportation by setting up lifting components, clamping components and auxiliary support mechanisms, ensure that the blades are safe and intact during transportation, and achieve the effect of improving transportation efficiency and reliability. By setting up support components and limit components, it is ensured that it can adapt to different wind load conditions, improve the fixing effect, and achieve the effect of improving the adjustment ability and safety during transportation.

[0010] The lifting assembly includes a servo motor and a special-shaped support frame fixedly connected to the top of the fixed frame. The output shaft sleeve of the servo motor is provided with a winding wheel. A steel wire rope is wound around the surface of the winding wheel.

[0011] By adopting the above scheme, through the setting of the lifting component, when the wind blade needs to be lifted for obstacle avoidance, the servo motor is operated, and the output shaft of the servo motor drives the winding wheel to rotate, so that the wire rope is wound around the winding wheel. At this time, the wire rope at the upper end pulls the swing component by penetrating the special-shaped support frame, and the wire rope at the lower end is relaxed, so that the wind blade is lifted with the swing ball as the axis, thereby lifting the wind blade.

[0012] Furthermore, the swing assembly includes a swing frame arranged between the special-shaped support frame and the wind blade, the upper and lower ends of the swing frame are provided with rope locking holes, the two ends of the steel wire rope respectively penetrate the two rope locking holes and are hinged to the outside of the swing frame, and the swing frame is provided with a swing groove on the surface of one side close to the special-shaped support frame, the inner wall of the swing groove is movably connected to the outer wall of the swing ball, the outer wall of the swing frame is fixedly connected to a plurality of evenly distributed sliding frames, and the outer walls of the plurality of sliding frames are slidably connected to clamping assemblies.

[0013] By adopting the above scheme, through the setting of the swing assembly, the steel wire rope at the upper end pulls the swing frame close to the special-shaped support frame by penetrating the special-shaped support frame and the upper rope locking hole, and the steel wire rope at the lower end pulls the swing frame away from the special-shaped support frame by penetrating the special-shaped support frame and the lower rope locking hole, so that the wind blade is lifted, and it is movably connected with the swing ball through the swing groove.

[0014] Furthermore, the clamping assembly includes two flexible pads overlapped on the inner and outer sides of the wind blade, and the two flexible pads are respectively hinged with an inner clamping plate and an outer clamping plate on the side away from the wind blade.

A locking bolt is hinged between the inner clamping plate and the outer clamping plate.

[0015] By adopting the above scheme, a clamping assembly is set up, and suitable flexible pads are selected and placed on the inner and outer sides of the wind blade head. Then, the inner and outer clamping plates are operated on the sliding frame to clamp the wind blade head, and the locking bolts are used to lock it, thereby achieving a stable clamping effect.

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

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

[0018] By adopting the above scheme, through the auxiliary support mechanism, the steering device and the telescopic hydraulic rod operate synchronously while the wind blades are lifted. The steering device is responsible for the steering of the telescopic hydraulic rod. The telescopic hydraulic rod is extended and the rotating shaft is supported against the turntable to support the lifted limit frame. When the carrying vehicle turns, the turntable can be rotated at the connecting plate to make steering more convenient, thereby improving the lifting and obstacle avoidance capability of large wind turbine blades during transportation, ensuring that the blades are safe and intact during transportation, and achieving the effect of improving transportation efficiency and reliability.

[0019] Furthermore, the support assembly includes a support spring fixedly mounted on the top of the fixing frame, the top of the support spring is fixedly connected with a support plate, and a plurality of arc-shaped support pads are arranged between the support plate and the wind blade.

[0020] Furthermore, the top of the support plate is fixedly connected with a movable hinge, and the movable hinge is installed between two adjacent arc-shaped support pads. The internal thread of the support plate is connected with a lifting bolt, 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 scheme, through the support assembly, when encountering strong winds or bumpy roads, the wind blades will shake. The arc-shaped support pad fixed to the bottom of the wind blade by the lifting bolts, and the support spring between the support plate and the fixing frame can provide shock absorption, thereby ensuring that it can adapt to different wind load conditions, improving the fixing effect, and achieving the effect of improving the adjustment ability and safety during transportation.

Both the flexible pull rope and the flexible rope are elastic, which can provide a certain pulling force and shock absorption effect when the wind blade shakes.

[0025] 1. Through the provided lifting assembly and supporting assembly, when the wind blade needs to be lifted for obstacle avoidance, the servo motor is operated, and the output shaft of the servo motor drives the winding wheel to rotate, so that the wire rope circles on the winding wheel. At this time, the wire rope at the upper end pulls the swing assembly by penetrating the special-shaped support frame, and the wire rope at the lower end is relaxed, so that the wind blade is lifted with the swing ball as the axis. At the same time, the steering device and the telescopic hydraulic rod operate synchronously, and the steering device is responsible for the steering of the telescopic hydraulic rod.

The flexible pads are changed according to the different diameters of the wind blade heads. At the same time, the inner and outer clamping plates slide on the slide frame through the sliding groove to adapt to wind blades of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Reference Figure 4 The lifting assembly 22 includes a servo motor 221 and a special-shaped support frame 224 fixedly connected to the top of the fixing frame 21. The output shaft sleeve of the servo motor 221 is provided with a winding wheel 222. A steel wire rope 223 is wound around the surface of the winding wheel 222. Both ends of the steel wire rope 223 respectively penetrate the upper and lower ends of the special-shaped support frame 224 and extend toward the direction of the wind blade 3. A swing ball 225 is fixedly installed on the inner wall of the special-shaped support frame 224, and the outer wall of the swing ball 225 is movably connected to the swing assembly 23.

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

[0046] By setting the lifting component 22, when the wind blade 3 needs to be lifted for obstacle avoidance, the servo motor 221 is operated, and the output shaft of the servo motor 221 drives the winding wheel 222 to rotate, so that the wire rope 223 is wound around the winding wheel 222. At this time, the wire rope 223 at the upper end pulls the swing component 23 by penetrating the special-shaped support frame 224, and the wire rope 223 at the lower end is relaxed, so that the wind blade 3 is lifted with the swing ball 225 as the axis, thereby lifting the wind blade 3.

[0047] Reference Figure 5 - Figure 6The swing assembly 23 includes a swing frame 231 arranged between the special-shaped support frame 224 and the wind blade 3, and rope locking holes 232 are provided at the upper and lower ends of the swing frame 231. The two ends of the wire rope 223 respectively penetrate the two rope locking holes 232 and are hinged to the outer side of the swing frame 231. A swing groove 233 is provided on the surface of the swing frame 231 on one side close to the special-shaped support frame 224. The inner wall of the swing groove 233 is movably connected to the outer wall of the swing ball 225. The outer wall of the swing frame 231 is fixedly connected with a plurality of evenly distributed sliding frames 234, and the outer walls of the plurality of sliding frames 234 are slidably connected with the clamping assembly 24.

[0048] Through the swing assembly 23, the steel wire rope 223 at the upper end pulls the swing frame 231 close to the special-shaped support frame 224 by penetrating the special-shaped support frame 224 and the locking rope hole 232 at the upper end, and the steel wire rope 223 at the lower end pulls the swing frame 231 away from the special-shaped support frame 224 by penetrating the special-shaped support frame 224 and the locking rope hole 232 at the lower end, so that the wind blade 3 is lifted, and is movably connected with the swing ball 225 through the swing groove 233. When the wind blade 3 shakes, the wind blade 3 will not be locked, thereby avoiding damage to the wind blade 3 due to the shaking.

[0049] Reference Figure 6 The clamping assembly 24 includes two flexible pads 244 overlapped on the inner and outer sides of the wind blade 3, and the two flexible pads 244 are hinged with an inner clamping plate 241 and an outer clamping plate 242 on the side away from the wind blade 3. The inner walls of the inner clamping plate 241 and the outer clamping plate 242 are both provided with sliding grooves 243, and the inner walls of the sliding grooves 243 are slidably connected to the outer walls of the sliding frame 234, and 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 heads of wind blades 3 of different diameters, so that the clamping assembly 24 can fit wind blades 3 of different sizes. At the same time, the inner clamping plate 241 and the outer clamping plate 242 slide on the slide frame 234 through the sliding groove 243, and can also adapt to wind blades 3 of different sizes.

[0051] By setting up the clamping assembly 24, an appropriate flexible pad 244 is selected and placed on the inner and outer sides of the head of the wind blade 3, and 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 blade 3, and the locking bolt 245 is used to lock it, thereby achieving a stable clamping effect.

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

[0053] Through the auxiliary support mechanism 4, the wind blade 3 is lifted and the steering device 46 and the telescopic hydraulic rod 45 operate synchronously. The steering device 46 is responsible for the steering of the telescopic hydraulic rod 45. The telescopic hydraulic rod 45 is extended and the rotating shaft 44 is pressed against the turntable 43 to support the lifted limit frame 411. When the carrying vehicle 1 turns, the turntable 43 can be rotated at the connecting plate 42 to make the steering more convenient, thereby improving the lifting and obstacle avoidance capability of large wind power blades during transportation, ensuring that the blades are safe and intact during transportation, and achieving the effect of improving transportation efficiency and reliability.

[0054] During use, a crane is used to hoist the wind blade 3 together with the limit frame 411 onto the carrying vehicle 1 and the auxiliary vehicle 5, and an appropriate flexible pad 244 is selected and placed on the inner and outer sides of the head of the wind blade 3, and 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 blade 3, and the locking bolt 245 is used to lock it. At the same time, the limit frame 411 is installed on the connecting plate 42 to complete the loading. When the wind blade 3 needs to be lifted for obstacle avoidance, the servo motor 221 is operated, and the output shaft of the servo motor 221 drives the winding wheel 222 to rotate, so that the wire rope 223 is circled on the winding wheel 222. At this time, the wire rope 223 at the upper end passes through the special-shaped support frame 224 and the upper The locking rope hole 232 on the square side pulls the swing frame 231 close to the special-shaped support frame 224, and the wire rope 223 at the lower end is loosened, so that the wind blade 3 is lifted with the swing ball 225 as the axis. When the wind blade 3 is lifted, the steering device 46 and the telescopic hydraulic rod 45 operate synchronously, and the steering device 46 is responsible for the steering of the telescopic hydraulic rod 45. The telescopic hydraulic rod 45 is extended and the rotating shaft 44 is pressed against the turntable 43 to support the lifted limit frame 411. When the carrying vehicle 1 turns, the turntable 43 can be rotated at the connecting plate 42 to make steering more convenient, thereby improving the lifting and obstacle avoidance ability of large wind power generation blades in transportation, ensuring that the blades are safe and intact during transportation, and achieving the effect of improving transportation efficiency and reliability.

[0055] Example 2, reference Fig. 9 - Fig.12 , which is the second embodiment of the present invention, and which is different from the first embodiment in that: Fig. 9The support assembly 25 includes a support spring 252 fixedly installed on the top of the fixing frame 21, the top of the support spring 252 is fixedly connected to a support plate 251, a plurality of arc-shaped support pads 254 are arranged between the support plate 251 and the wind blade 3, the top of the support plate 251 is fixedly connected to a movable hinge 253, the movable hinge 253 is installed between two adjacent arc-shaped support pads 254, the internal thread of the support plate 251 is connected to a lifting bolt 255, and 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 arranged between two adjacent arc-shaped support pads 254, so that multiple arc-shaped support pads 254 are connected into a whole, and can be rotated according to the head diameter of wind blades 3 of different sizes under the adjustment of the lifting bolt 255, so that the arc-shaped support pad 254 fits the outer wall of the wind blade 3.

[0057] By setting up the support assembly 25, when encountering strong winds or bumpy roads, the wind blade 3 will shake. The arc-shaped support pad 254 fixed to the bottom of the wind blade 3 by the lifting bolt 255, and the support spring 252 between the support plate 251 and the fixing frame 21 can provide shock absorption, thereby ensuring that it can adapt to different wind load conditions, improving the fixing effect, and achieving the effect of improving the adjustment ability and safety during transportation.

[0058] Reference Fig.10 The limiting assembly 41 also includes a plurality of flexible ropes 413 fixedly mounted on the outer wall of the wind blade 3, the outer walls of the plurality of flexible ropes 413 are fixedly connected with a plurality of flexible pull ropes 412, and the ends of the plurality of flexible pull ropes 412 away from the wind blade 3 are hinged to the outer wall of the limiting frame 411.

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

[0060] By setting the limiting component 41, the limiting frame 411 is installed at the center of gravity of the wind blade 3, and the flexible rope 413 is put on the outer wall of the wind blade 3 and tightened to fit, and then the flexible pull rope 412 is used to fix the flexible rope 413 in the middle of the limiting frame 411. The flexible pull rope 412 and the flexible rope 413 are both elastic, which can provide a certain pulling force and shock absorption effect when the wind blade 3 shakes.

[0061] During use, first install the limit frame 411 at the center of gravity of the wind blade 3, use the flexible rope 413 to cover the outer wall of the wind blade 3, tighten and fit, and then use the flexible pull rope 412 to fix the flexible rope 413 in the middle of the limit frame 411, and then load it. When encountering strong winds or bumpy roads, the wind blade 3 will shake. 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 blade 3 by the lifting bolt 255 during loading, and the support spring 252 between the support plate 251 and the fixing frame 21 can all provide shock absorption, thereby ensuring that it can adapt to different wind load conditions, improve the fixing effect, and achieve the effect of improving the adjustment ability and safety during transportation. The rest of the structure is the same as that of Example 1.

[0062] Working principle of the present invention:

[0063] Before loading, the limit frame 411 is installed at the center of gravity of the wind blade 3, and the flexible rope 413 is put on the outer wall of the wind blade 3 and pulled tight, and then the flexible pull rope 412 is used to fix the flexible rope 413 in the middle of the limit frame 411. The flexible pull rope 412 and the flexible rope 413 are both elastic, which can provide a certain pulling force and shock absorption effect when the wind blade 3 shakes.

[0064] During loading, a crane is used to hoist the wind blade 3 together with the limit frame 411 onto the carrying vehicle 1 and the auxiliary vehicle 5, and an appropriate flexible pad 244 is selected and placed on the inner and outer sides of the head of the wind 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 blade 3, and the locking bolt 245 is used to lock it. At the same time, the limit frame 411 is installed on the connecting plate 42 to complete the loading.

[0065] When the wind blade 3 needs to be lifted for obstacle avoidance, the servo motor 221 is operated, and the output shaft of the servo motor 221 drives the winding wheel 222 to rotate, so that the wire rope 223 is wound around the winding wheel 222. At this time, the wire rope 223 at the upper end penetrates the special-shaped support frame 224 and the rope locking hole 232 above to pull the swing frame 231 close to the special-shaped support frame 224, while the wire rope 223 at the lower end is relaxed, so that the wind blade 3 is lifted with the swing ball 225 as the axis.

[0066] When the wind 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 is extended, and the rotating shaft 44 is pressed against the turntable 43 to support the lifted limit frame 411. When the carrying vehicle 1 turns, the turntable 43 can be rotated at the connecting plate 42 to make steering more convenient, thereby improving the lifting and obstacle avoidance ability of large wind power generation blades during transportation, ensuring that the blades are safe and intact during transportation, and achieving the effect of improving transportation efficiency and reliability.

[0067] When encountering strong winds or bumpy roads, the wind blades 3 will shake. In addition to the pulling and shock absorption of the flexible pull rope 412 and the flexible sleeve rope 413, the arc-shaped support pad 254 fixed to the bottom of the wind blade 3 by the lifting bolt 255 during loading, and the support spring 252 between the support plate 251 and the fixing frame 21 can provide shock absorption, thereby ensuring that it can adapt to different wind load conditions, improving the fixing effect, and achieving the effect of improving the adjustment ability and safety during transportation.
