Description

Technical Field

[0001] This invention relates to the field of wind turbine blade transportation equipment, and in particular to a transportation and fixing device for wind turbine blades and its usage method. Background Technology

[0002] With the development of renewable energy technologies, wind power, as a clean and renewable energy source, has been widely used globally. Wind turbines are the core equipment in wind power generation, and their blades, as key components for capturing wind energy, are constantly increasing in size and mass with advancements in wind power technology. This presents new challenges for the transportation and installation of these blades.

[0003] Most existing wind turbine blade transport and fixing devices use a single-blade fixing method. This fixing method has low transport efficiency. Furthermore, because the width of the blade varies at different positions, the existing fixing devices cannot be adjusted in height during use, so the adaptation effect on the blade is generally poor.

[0004] Therefore, in order to further improve the applicability and efficiency of blade transportation and fixing, we propose a wind turbine blade transportation and fixing device and its usage method. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the low transportation efficiency caused by the use of single-blade fixing methods. This invention proposes a transportation and fixing device and method for wind turbine blades.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a transport and fixing device for wind turbine blades, including:

[0008] Flatbed frame and several support mechanisms mounted on the flatbed frame;

[0009] Several of the aforementioned support mechanisms are arranged in two rows to support two blades, and a pressing mechanism for fixing the upper side of the blades is also provided above the flatbed frame.

[0010] The support mechanism includes a base plate connected to the flatbed frame, and a load-bearing component is connected above the base plate via a telescopic assembly. The load-bearing component has an inlet for accommodating the blade.

[0011] Furthermore, the bearing assembly includes a connecting seat, and clamps are rotatably connected to both sides of the connecting seat;

[0012] An angle locking structure is provided between the clamping plate and the connecting seat, and the insertion port is formed between the tops of the two clamping plates.

[0013] Furthermore, in the symmetrical portions of the two clamps, the insertion port has a V-shaped structure.

[0014] Furthermore, the angle locking structure includes a positioning glass bead embedded on the outside of the connecting seat, and a plurality of positioning holes are circumferentially distributed on the end face of the clamping plate, wherein the telescopic end of the positioning glass bead engages with the positioning hole.

[0015] Furthermore, the telescopic assembly includes a sleeve fixed to the base plate, and a plug rod fixedly connected to the bottom of the connecting seat, the plug rod being inserted into the sleeve.

[0016] Furthermore, it also includes a screw fixed to the bottom of the connecting seat, and a threaded sleeve rotatably connected above the base plate, the threaded sleeve being threadedly connected to the screw.

[0017] Furthermore, the pressing mechanism includes a guide tube fixed on the flatbed frame, a movable rod movably inserted into the inner side of the guide tube, and a driving component for driving the movable rod fixedly installed at the bottom of the guide tube;

[0018] The top of the movable rod has a snap-fit ​​structure.

[0019] Furthermore, a Z-shaped guide groove is provided on the outer side of the guide tube, and a guide shaft that slides in the Z-shaped guide groove is fixedly installed on the outer side of the movable rod.

[0020] Furthermore, the snap-fit ​​structure includes a crossbar fixed to the top of the movable rod, both ends of the crossbar having through slots, and a pressure block being slidably connected in the through slot via a guide rod. Springs are provided between the two sides of the pressure block and the inner wall of the through slot, and a V-shaped block is fixedly installed at the bottom of the pressure block.

[0021] Furthermore, this invention also proposes a method for using a transport and fixing device for wind turbine blades, which utilizes the aforementioned device and includes the following steps:

[0022] Adjust the height of the load-bearing components according to the support position to ensure that the central axis of the fan blades is horizontal with the top plane of the flatbed frame;

[0023] The blades are hoisted onto the rows of support mechanisms using a crane;

[0024] Control the movement of the pressing mechanism to press down and fix the two blades on both sides, thus completing the support and fixation of the blades. Connecting the vehicle head will enable transportation.

[0025] The present invention proposes a wind turbine blade transport and fixing device and method, which has the following advantages: By adopting a support mechanism distributed in two rows, two blades can be installed and fixed at the same time, thereby improving the transport efficiency. Secondly, the height of the insertion inlet on the upper side of several support mechanisms can be adaptively adjusted to ensure that the central axis of the blade is horizontal with the top of the flatbed frame during installation, thereby ensuring the stability of the blade during transport. In addition, the pressing mechanism is used to fix the top of the two blades at the same time, further optimizing the fixing efficiency and ensuring the convenience and reliability of transport and fixing operations.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Reference Figures 1-5 As an embodiment of the present invention, a transport and fixing device for wind turbine blades is disclosed. Specifically, the device includes a flatbed frame 1 and a plurality of support mechanisms 2 mounted on the flatbed frame 1. In this embodiment, the flatbed frame 1 is used to connect the truck head to realize traction movement. The truck head can be a semi-trailer.

[0034] Several of the support mechanisms 2 are arranged in two rows to support two blades 3. That is, this fixing device can install and fix two blades 3 at one time to improve the conveying efficiency. A pressing mechanism 4 for fixing the upper side of the blades 3 is also provided above the flatbed frame 1.

[0035] The support mechanism 2 includes a base plate 21 connected to the flatbed frame 1. A load-bearing component 23 is connected above the base plate 21 via a telescopic component 22. The load-bearing component 23 has an inlet 24 for accommodating the blade 3.

[0036] In some embodiments, the bearing component 23 of the present invention includes a connecting seat 231, and clamping plates 232 are rotatably connected to both sides of the connecting seat 231.

[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 this embodiment, the two clamping plates 232 are symmetrical, and the insertion port 24 has a V-shaped structure. That is to say, the design of two rotatable clamping plates 232 in this invention can adapt and adjust the opening and closing angle between the two clamping plates 232 according to the different width requirements of the blade 3 to be supported. In this way, it can be adapted to different support positions of the blade 3, which greatly improves the stability and adaptability of the support.

[0039] Based on the above embodiments, the angle locking structure in this embodiment includes a positioning glass bead 233 embedded on the outside of the connecting seat 231, and a plurality of positioning holes 234 are distributed circumferentially on the end face of the clamping plate 232. The telescopic end of the positioning glass bead 233 is engaged with the positioning hole 234.

[0040] In this embodiment, the rotation angle of the clamping plate 232 is fixed by using a snap-fit ​​method between the positioning glass beads 233 and the positioning holes 234. It should be noted that in this embodiment, several positioning holes 234 are distributed circumferentially along the rotation position of the clamping plate 232. In addition, the structure of the positioning glass beads 233 is existing technology and will not be described in detail here.

[0041] In some embodiments, the telescopic component 22 of the present invention includes a sleeve 221 fixed on the base plate 21, and an insertion rod 222 fixedly connected to the bottom of the connecting seat 231, the insertion rod 222 being inserted into the sleeve 221.

[0042] In order to drive the connecting seat 231 to move, the present invention also includes a screw 223 fixed to the bottom of the connecting seat 231, and a threaded sleeve 224 rotatably connected above the base plate 21, the threaded sleeve 224 being threadedly connected to the screw 223.

[0043] The purpose of the telescopic component 22 in this invention is to adjust the height of the bearing component 23 during the initial installation of the support mechanism 2. This allows the height of the inlet 24 of multiple support mechanisms 2 to be adapted to the different position dimensions of the blade 3, ensuring that the axis of the blade 3 is horizontal with the top of the flatbed frame 1 during installation, thereby ensuring the stability of the blade 3 during transportation.

[0044] Furthermore, in this embodiment, the pressing mechanism 4 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. A driving component 43 for driving the movable rod 42 is fixedly installed at the bottom of the guide tube 41. Preferably, in this embodiment, the driving component 43 is set as an electric actuator. Specifically, in this embodiment, a portion of the guide tube 41 extends to the bottom of the flatbed frame 1, and the driving component 43 is fixed at the bottom end of the guide tube 41.

[0045] The top of the movable rod 42 has a snap-fit ​​structure, which is used to snap and fix the top of the blade 3, and together with the clamp 232, completes 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 that slides in the Z-shaped guide groove 44 is fixedly installed on the outer side of the movable rod 42. Specifically, the design of the guide shaft 45 and the Z-shaped guide groove 44 in this invention is to realize the rotation drive of the movable rod 42. That is, when the movable rod 42 moves down, the snap-fit ​​structure is directly above the blade 3. In the initial state, it is horizontal between the two blades 3, so as to avoid interference with the hoisting of the blade 3.

[0047] Based on the above embodiments, the snap-fit ​​structure of the present invention includes a crossbar 46 fixed to the top of the movable rod 42. Both ends of the crossbar 46 are provided with through grooves. A pressure block 48 is slidably connected in the through groove through a guide rod 47. Springs 49 are provided between the two sides of the pressure block 48 and the inner wall of the through groove. 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 in the extended state controlled by the driving component 43, and the crossbar 46 is horizontal between the two blades 3, so as to avoid interference with the hoisting of the blades 3;

[0049] When the blade 3 needs to be fixed after hoisting, the drive component 43 controls the movable rod 42 to move down. At this time, the movable rod 42 will rotate when it moves down. After rotation, the two V-shaped blocks 481 on both sides of the crossbar 46 are aligned with the top of the two blades 3. Of course, in order to achieve the snap-fit ​​adaptation to different positions of the top of the blade 3 in this 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 top corner of the blade 3 within a small range.

[0050] Furthermore, as the movable rod 42 continues to move downward, it generates linear movement until the V-block 481 engages with the top of the blade 3, thus completing the fixation of the blade 3.

[0051] It should be noted that this invention also proposes a method for using a wind turbine blade transport and fixing device, which utilizes the aforementioned device. The specific method includes the following steps:

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

[0053] The blades are hoisted onto the rows of support mechanisms 2 using a crane;

[0054] Control the movement of the pressing mechanism 4 to press down and fix the two blades 3 on both sides, thus completing the support and fixation of the blades 3. Then, connect the vehicle head to realize transportation.

[0055] In summary, by employing two rows of support mechanisms 2, the present invention can install and fix two blades 3 at once, thereby improving the conveying efficiency. Secondly, the height of the inlet 24 on the upper side of several support mechanisms 2 can be adjusted to ensure that the central axis of the blade 3 is horizontal with the top of the flatbed frame 1 during installation, thus ensuring the stability of the blade 3 during conveying. In addition, the pressing mechanism 4 is used to fix the top of the two blades 3 simultaneously, further optimizing the fixing efficiency and ensuring the convenience and reliability of the conveying and fixing operation.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
