[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0033] Reference Figure 1-5 An embodiment of the present invention discloses a transport and fixing device for wind turbine blades. Specifically, the device comprises a flat frame 1 and a plurality of support mechanisms 2 mounted on the flat frame 1. The flat frame 1 in this embodiment is used to connect a vehicle head to achieve traction movement. The vehicle head can be a semi-trailer.

[0034] The plurality of support mechanisms 2 are distributed in two rows and are used to carry two blades 3, that is, the fixing device can realize the installation and fixing of two blades 3 at a time to improve the conveying efficiency. A pressing mechanism 4 for fixing the upper side of the blade 3 is also provided above the flatbed frame 1;

[0035] The support mechanism 2 includes a bottom plate 21 connected to the flatbed frame 1 , and a bearing assembly 23 is connected to the top of the bottom plate 21 via a telescopic assembly 22 , and the bearing assembly 23 has an inlet 24 for accommodating the blade 3 .

[0036] In some embodiments, the bearing assembly 23 of the present invention includes a connecting seat 231, and both sides of the connecting seat 231 are rotatably connected with a clamping plate 232;

[0037] An angle locking structure is provided between the clamping plate 232 and the connecting seat 231 , and the insertion port 24 is formed between the tops of the two clamping plates 232 .

[0038] Furthermore, in the present embodiment, the two clamping plates 232 are symmetrical parts, and the insertion opening 24 is in a V-shaped structure. That is to say, the present invention adopts a design of two rotatable clamping plates 232, which can adapt to the opening and closing angle between the two clamping plates 232 according to the different width requirements of the blades 3 to be supported. In this way, adaptation to different supporting positions of the blades 3 can be achieved, which greatly improves the stability and adaptability of the support.

[0039] On the basis of the above-mentioned embodiment, the angle locking structure described in this embodiment includes a positioning glass bead 233 embedded on the outer side of the connecting seat 231, and a plurality of positioning holes 234 are circumferentially distributed on the end face of the clamping plate 232, and the telescopic end of the positioning glass bead 233 is snap-fitted with the positioning hole 234.

[0040] In the present embodiment, the rotation angle of the clamping plate 232 is fixed by clamping the positioning glass bead 233 and the positioning hole 234. It should be pointed out that in the present embodiment, several of the positioning holes 234 are distributed along the circumference of the rotation position of the clamping plate 232. In addition, the structure of the positioning glass bead 233 is prior art and will not be elaborated here.

[0041] In some embodiments, the telescopic assembly 22 of the present invention includes a sleeve 221 fixed on the base plate 21 , and a plug rod 222 is fixedly connected to the bottom of the connecting seat 231 , and the plug rod 222 is plugged into the sleeve 221 .

[0042] Of course, in order to drive the connection seat 231 to move, the present invention also includes a screw rod 223 fixed to the bottom of the connection seat 231 , and a threaded sleeve 224 is rotatably connected above the bottom plate 21 , and the threaded sleeve 224 is threadedly connected to the screw rod 223 .

[0043] The telescopic component 22 of the present invention is designed to be able to adjust and adapt the height of the bearing component 23 through the telescopic component 22 when the support mechanism 2 is initially installed, so that the height of the insertion openings 24 of multiple support mechanisms 2 can be adapted to the different position sizes of the blades 3 to ensure that the axis of the blades 3 is level with the top of the flatbed frame 1 when they are installed, thereby ensuring the stability of the blades 3 during transportation.

[0044] In addition, the pressing mechanism 4 in this embodiment includes a guide tube 41 fixed on the flatbed frame 1, a movable rod 42 is movably inserted into the inner side of the guide tube 41, and a driving member 43 for driving the movable rod 42 is fixedly installed at the bottom of the guide tube 41. As a preferred embodiment, the driving member 43 in this embodiment is set as an electric push rod. Specifically, a part of the guide tube 41 in this embodiment extends to the bottom of the flatbed frame 1, and the driving member 43 is fixed to the bottom end of the guide tube 41;

[0045] The top of the movable rod 42 has a clamping structure, and the clamping structure is used to clamp and fix the top of the blade 3, and cooperates with the clamping plate 232 to complete the fixation of the blade 3.

[0046] It should be noted that, in this embodiment, a Z-shaped guide groove 44 is provided on the outer side of the guide tube 41, and a guide shaft 45 sliding in the Z-shaped guide groove 44 is fixedly installed on the outer side of the movable rod 42. Specifically, the guide shaft 45 and the Z-shaped guide groove 44 are designed in the present invention to realize the rotational drive of the movable rod 42, that is, when the movable rod 42 moves downward, the clamping structure is directly above the blade 3, and in the initial state, it is horizontally and vertically between the two blades 3, so as to avoid interference with the lifting of the blade 3.

[0047] On the basis of the above-mentioned embodiment, the clamping structure in the present invention includes a cross bar 46 fixed to the top end of the movable rod 42, and through grooves are provided at both ends of the cross bar 46. A pressure block 48 is slidably connected in the through groove through a guide rod 47, and springs 49 are arranged between the two sides of the pressure block 48 and the inner wall of the through groove, wherein a V-shaped block 481 is fixedly installed at the bottom of the pressure block 48.

[0048] Specifically, in the initial state, the movable rod 42 is controlled by the driving member 43 to be in an extended state, and at this time, the cross bar 46 is horizontally and vertically between the two blades 3, so as to avoid interference with the lifting of the blades 3;

[0049] When the blade 3 needs to be fixed after the lifting is completed, the driving member 43 controls the movable rod 42 to move downward. At this time, the movable rod 42 will rotate when it moves downward. After the rotation, the two V-shaped blocks 481 on both sides of the cross bar 46 are aimed at the tops of the two blades 3. Of course, in order to achieve the card connection adaptation at different positions of the top of the blade 3 in the present invention, the V-shaped block 481 adopts a movable design, that is, it can slide inside the guide groove to adapt to different positions of the upper side vertex angle of the blade 3 within a small range;

[0050] Furthermore, when the movable rod 42 continues to move downward, a linear movement is generated until the V-shaped block 481 is engaged with the top of the blade 3 to complete the fixation of the blade 3.

[0051] It should be noted that the present invention also proposes a method for using a wind turbine blade transportation and fixing device, which uses the above-mentioned device. Specifically, the method includes the following steps:

[0052] The height of the bearing assembly 23 is adjusted according to the support position to ensure that the central axis of the fan blade is level with the top plane of the flatbed frame 1;

[0053] The blades are hoisted onto a plurality of the support mechanisms 2 distributed in a row by a crane;

[0054] The movement of the pressing mechanism 4 is controlled to press down and fix the two blades 3 on both sides, thereby completing the support and fixation of the blades 3, and the transportation can be realized by connecting the vehicle head.

[0055] In summary, the present invention adopts support mechanisms 2 distributed in two rows, so that two blades 3 can be installed and fixed at one time to improve the conveying efficiency. Secondly, the height of the inlet 24 on the upper side of the support mechanisms 2 can be adaptively adjusted to ensure that the axis of the blade 3 is level with the top of the flatbed frame 1 when it is installed, thereby ensuring the stability of the blade 3 during transportation. In addition, the tops of the two blades 3 are fixed simultaneously in cooperation with the pressing mechanism 4, which further optimizes the fixing efficiency and ensures the convenience and reliability of the conveying and fixing operation.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
