Description

Technical Field

[0001] The present invention relates to the technical field of blade transport auxiliary devices, and in particular to a wind turbine blade transport balance auxiliary mechanism and a use method thereof. Background Art

[0002] As global demand for renewable energy continues to increase, wind power, as a clean, renewable energy source, has seen rapid technological and market development. As the core component of wind turbines, wind turbine blades are crucial for converting natural wind energy into electrical energy. Their design and technical expertise directly impact the performance and efficiency of the entire wind turbine.

[0003] Currently, the transportation of large wind turbine blades primarily relies on large semi-trailers. However, due to the blades' typically long length and irregular curved surface, they face the challenge of poor stability during transportation. Existing fixing methods primarily secure the blades at their ends, while the middle portion is compressed and tied with ropes. Because blades have a certain degree of toughness, compression-binding only applies force to the upper portion. If the blades are not properly supported at the bottom during transportation, they can easily wobble, potentially causing damage.

[0004] Based on this, in order to improve the balance of force on the blades during transportation, we propose a wind turbine blade transportation balance auxiliary mechanism and a method for use. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art that the compression binding method only realizes the upper force, and if the bottom of the blade is not well supported during actual transportation, it is easy to cause the blade to shake. A wind turbine blade transportation balance auxiliary mechanism and usage method are proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] Design a wind turbine blade transport balance auxiliary mechanism, including a fixing frame installed on a vehicle plate for fixing the blades;

[0008] and a plurality of support units fixed on the vehicle plate, wherein the support units are used to support and fix the blades;

[0010] Further, the lifting assembly includes two first arms rotatably connected to the bottom plate, and two second arms rotatably connected to the top of the top plate;

[0011] The two first arms and the two second arms are arranged opposite to each other, and the ends of the first arms and the second arms are connected and rotated via a rotating seat.

[0012] Furthermore, a double-headed screw is threadedly connected between the two rotating seats, and the tightening assembly is arranged between the two second arms.

[0013] Furthermore, side panels are fixedly mounted on both sides of the bottom panel, and a safety structure is provided between the side panels and the top panel.

[0014] Furthermore, the safety structure includes a sleeve pinned and rotated on the side plate, a connecting rod pinned and rotated on the side of the top plate, and an end of the connecting rod is inserted into the sleeve;

[0015] A locking structure is provided between the sleeve and the connecting rod.

[0016] Furthermore, the locking structure includes a plurality of teeth formed on the bottom of the connecting rod, and an outward expansion portion is formed at the end of the sleeve. A plug rod is inserted into the outward expansion portion through a spring, and the end of the plug rod has a clamping end that is clamped between two adjacent teeth.

[0017] Furthermore, the tightening assembly includes a strap fixed to one of the second arms, and a buckle is fixed to the end of the strap;

[0018] A connecting seat is provided on the end surface of the other second arm, and a claw connected to the buckle is provided on the end surface of the connecting seat.

[0023] Adjust the top of the top plate according to the height of the blades at different positions to ensure that the top of the top plate can support the bottom of the blades;

[0024] After the bottom support adjustment of the blade is completed, the top of the blade is fixed by a clamping assembly, so that the blade reaches an overall force balance state.

[0025] The present invention proposes a wind turbine blade transportation balancing auxiliary mechanism and a method of use, which have the following beneficial effects: the present invention adopts a design of several support units to support the bottom of the blade.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figure 1-6An embodiment of the present invention discloses a wind turbine blade transport balancing auxiliary mechanism, the auxiliary mechanism comprising a fixing frame 3 mounted on a vehicle plate 1 for fixing a blade 2. The fixing frame 3 in this embodiment is fixedly connected to the end of the blade 2 by fasteners such as bolts to ensure the stability of the connection to the blade 2.

[0035] and a plurality of support units 4 fixed on the vehicle plate 1, wherein the support units 4 are distributed in a straight line to support the tail ends of the blades 2 at intervals, and the support units 4 are used to support and fix the blades 2;

[0036] The support unit 4 includes a bottom plate 41 and a top plate 42, the upper end of the top plate 42 abuts against the lower side of the blade 2; a lifting component 43 is provided between the bottom plate 41 and the top plate 42, and a tightening component 44 is also provided on the lifting component 43 and is sleeved on the upper side of the blade 2.

[0037] In some embodiments, the lifting assembly 43 of the present invention includes two first arms 431 rotatably connected to the bottom plate 41 , and two second arms 432 rotatably connected to the top of the top plate 42 ;

[0038] The two first arms 431 and the two second arms 432 are disposed opposite to each other, and ends of the first arms 431 and the second arms 432 are connected and rotated via a rotating base 433 .

[0039] Furthermore, in order to drive the first arm 431 and the second arm 432 to rotate, in this embodiment, a double-headed screw 434 is threadedly connected between the two rotating seats 433, and the clamping assembly 44 is arranged between the two second arms 432.

[0040] Since the thickness of the blade 2 decreases toward its tail end, in this embodiment, a double-headed screw 434 is used to drive the two rotating seats 433 to move relative to each other, thereby driving the first arm 431 and the second arm 432 to rotate, thereby adjusting the height of the top plate 42 to ensure support adaptability for different positions of the blade 2;

[0041] Of course, in order to ensure contact protection for the blade 2, a flexible pad 47 is also provided on the top of the top plate 42 in this embodiment, and the end face of the flexible pad 47 is provided with anti-slip grooves. Specifically, the flexible pad 47 can be set as a silicone pad. By adopting the design of anti-slip grooves, after the clamping component 44 fixes the upper side of the blade 2, the contact stability between the flexible pad 47 and the blade 2 can be improved, thereby optimizing the support and fixing effect of the blade 2.

[0042] It should be noted that in order to avoid deformation and damage of the first arm 431 or the second arm 432 during transportation, resulting in unstable support, in this embodiment, side panels 45 are fixedly installed on both sides of the base plate 41, and a safety structure 46 is provided between the side panels 45 and the top plate 42. The safety structure 46 is used to lock and fix the height of the top plate 42. Even if the first arm 431 or the second arm 432 is deformed and damaged, the height of the top plate 42 will not change, thereby ensuring the supporting effect of the top plate 42 on the blade 2.

[0043] Specifically, the safety structure 46 in this embodiment includes a sleeve 461 pinned and rotated on the side plate 45, and a connecting rod 462 pinned and rotated on the side of the top plate 42, and the end of the connecting rod 462 is inserted into the sleeve 461;

[0044] A locking structure is provided between the sleeve 461 and the connecting rod 462 .

[0045] On the basis of the above embodiment, the locking structure described in this embodiment includes a plurality of teeth 463 formed on the bottom of the connecting rod 462, and an outward expansion portion 464 is formed at the end of the sleeve 461. An insertion rod 466 is movably inserted into the outward expansion portion 464 through a spring 465, and the end of the insertion rod 466 has a clamping end 467 that is clamped between two adjacent teeth 463. The clamping end 467 described in this embodiment is set as a rectangular block, which is clamped with the teeth 463 to complete the position locking of the connecting rod 462.

[0046] It should be noted that the teeth 463 described in this embodiment are set as bevel teeth. By adopting the design of the bevel tooth structure, it can be ensured that when the top plate 42 moves upward and is lifted, the connecting rod 462 can move freely outward in the reverse direction. When subjected to reverse force, the clamping end 467 and the stop of the bevel tooth plane are used to prevent the connecting rod 462 from retracting.

[0047] That is to say, when supporting the blade 2, the double-headed screw 434 is rotated to drive the top plate 42 to move upward. During this process, the connecting rod 462 extends outward to adapt to the height change of the top plate 42. At the same time, since the teeth 463 are set as bevel teeth, the contact with the clamping end 467 can be freely extended in any direction. During transportation, when the first arm 431 and the second arm 432 are deformed and damaged, the connecting rod 462 cooperates with the sleeve 461 to support the top plate 42. This ensures the support stability of the top plate 42 and achieves the effect of safety protection. Of course, when disassembling, pull the plug 466 outward to move the top plate 42 downward.

[0048] In some embodiments, the tightening assembly 44 of the present invention includes a strap 441 fixed to one of the second arms 432 , and a buckle 442 is fixed to the end of the strap 441 ;

[0049] A connecting seat 443 is provided on the end surface of the other second arm 432 , and a claw 444 connected to the buckle 442 is provided on the end surface of the connecting seat 443 .

[0050] Of course, since the positions of the first arm 431 and the second arm 432 will change when they rotate, in order to ensure that the strap 441 can be tightly tied to the upper side of the blade 2, the second arm 432 with a connecting seat 443 in the present invention is provided with a slide 445, and the connecting seat 443 is slidably connected to the inner side of the slide 445, and the end of the slide 445 is also rotatably connected to a screw 446, and the screw 446 is threadedly connected to the connecting seat 443.

[0051] That is, after the bottom of the blade 2 is supported and adapted by several support units 4, the strap 441 can be pulled to be placed on the upper side of the blade 2, and the buckle 442 on the end of the strap 441 can be fastened into the claw 444. The claw 444 described in this embodiment is provided with a U-shaped structure. At this time, the screw 446 can be rotated to drive the connecting seat 443 to move linearly, and the connecting seat 443 drives the claw 444 to move to tighten the strap 441, thereby achieving the fixing operation of the top of the blade 2.

[0052] In addition, the present invention also discloses a method for using a wind turbine blade transport balance auxiliary mechanism, using the above mechanism, the specific method includes the following steps:

[0053] Hoist the blade 2 to the top of the vehicle plate 1 using a hoisting device, and connect and fix the end of the blade 2 to the fixing frame 3;

[0054] According to the height of the blade 2 at different positions, the top of the top plate 42 is adjusted to ensure that the top of the top plate 42 supports the bottom of the blade 2;

[0055] After the bottom support adjustment of the blade 2 is completed, the top of the blade 2 is fixed by a clamping assembly 44, so that the blade 2 reaches an overall force balance state.

[0056] In summary, the present invention adopts a design of several support units 4 to support the bottom of the blade 2. Since the height of the support unit 4 is adjustable, it can adapt to the support requirements of different positions of the blade 2. The tightening component 44 provided in conjunction is used to bind and fix the top of the blade 2 to achieve horizontal support for the blade 2, so that the blade 2 is in a force-balanced state as a whole, thereby avoiding the problem of shaking and damage of the blade 2 due to unstable support during transportation.

[0057] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
