[0002] Wind turbine blades are the core components of wind power equipment. They are large in size and have a special shape. During production, transportation and installation, the fixing and transfer of the blades are crucial.

[0003] Currently, there are many types of tooling devices used for transporting wind turbine blades on the market, but most of them have some obvious shortcomings. Some of the existing wind turbine blade transporting tooling devices adopt a simple fixed frame structure, and the blades are directly fixed to the frame by bolts and other fasteners.

[0004] While this structure can secure the blades to some extent, it lacks flexibility and cannot be precisely adjusted according to the specific dimensions of the blade root. Different models of wind turbine blades have different root dimensions. When using this fixing frame, blades of mismatched sizes cannot be securely fixed, requiring additional complex auxiliary fixing devices, which increases the difficulty and cost of operation. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a tooling for wind turbine blades, which effectively solves the issues in the prior art.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 and Figure 2 This invention discloses a wind turbine blade fixture, comprising a movable platform 5 and a connecting plate 101. The movable platform 5 has wheels 503 at its bottom. A movable platform 5 is fixedly connected to each end of the connecting plate 101. A support platform 3 is fixedly installed in the middle of the connecting plate 101. The support platform 3 includes a support block 301, which is fixedly installed in the middle of the connecting plate 101. A bottom fixing plate 302 is fixedly installed on the upper end of the support block 301, and the bottom fixing plate 302 has several bottom fixing holes 303. Support frames 4 are installed on both sides of the support block 301 on the connecting plate 101. Two support frames 4 are movably installed on the connecting plate 101, and are located on both sides of the support platform 3. (See also...) Figure 3 The support frame 4 is bolted to a side fixing plate 402, and the side fixing plate 402 has several side fixing holes 403.

[0025] Specifically, by setting up the support platform 3 and the bottom fixing plate 302, when transporting the wind turbine blade, the bottom fixing plate 302 is bolted to the blade end to form a fixed connection below the blade end. Then, by sliding the support frame 4, the side fixing plate 402 is brought close to both sides of the blade end and fixedly connected by bolts.

[0026] In this way, by setting up a sliding support frame 4, when the blade end is fixed on the support platform 3, the sliding support frame 4 can be adapted to wind turbine blades of different end sizes for installation and fixation, and the wind turbine blades can be transported by the moving wheels 503.

[0027] In some feasible embodiments, the connecting plate 101 is a rectangular plate, the moving platform 5 is a rectangular plate with a rectangular groove at the bottom, the two ends of the connecting plate 101 are fixedly installed in the rectangular groove, and the moving wheels 503 are fixedly installed at the bottom of the moving platform 5. The moving wheels 503 can be selected as power wheels or a traction device can be set in front of the moving platform 5 for movement.

[0028] The bearing block 301 is trapezoidal in shape. To facilitate the placement of the blades, the top of the bearing block 301 is arc-shaped. The bottom fixing plate 302 is rectangular in shape. Multiple bottom fixing holes 303 are provided, and the bottom fixing holes 303 are rectangular holes to facilitate the adjustment of the position of the fixing bolts.

[0029] The support frame 4 is a right-angled triangular frame. To facilitate sliding, a C-shaped part can be set at the bottom of the support frame 4, which can be slidably snapped onto the connecting plate 101. The hypotenuse of the support frame 4 faces the support platform 3. The side fixing plate 402 is installed on the hypotenuse of the support frame 4. The structure of the side fixing hole 403 is the same as that of the bottom fixing hole 303.

[0030] As a specific embodiment of the wind turbine blade tooling provided in the application, the support platform 3 is provided with slide rail plates 304 fixedly installed on the upper end of the connecting plate 101 on both sides, and the support frame 4 is provided with a first sleeve 401 and a second sleeve 404 on both sides of the bottom, and the first sleeve 401 and the second sleeve 404 are respectively slidably installed on the slide rail plates 304.

[0031] Overall, by setting the slide rail plate 304 and the first sleeve 401 and the second sleeve 404, the support frame 4 and the support platform 3 are connected, which improves the integrity and facilitates the support of the blade.

[0032] Furthermore, the connecting plate 101 is rotatably mounted with two drive screws 204, each of which is threadedly connected to a drive block 406. The drive blocks 406 are respectively fixedly connected to two support frames 4, and the drive screws 204 are connected to a drive motor 201.

[0033] It should be understood that by setting up the drive screw 204, drive motor 201 and drive block 406, the two support frames 4 can automatically adjust the distance.

[0034] Furthermore, the output end of the drive motor 201 is connected to a dual-output gearbox 202, and a connecting rod 203 is fixedly installed at the output end of the dual-output gearbox 202. The connecting rod 203 is connected to two drive screws 204 respectively.

[0035] It should be understood that by setting up a dual-output gearbox 202, the two drive screws 204 are driven by the same drive motor 201, maintaining the synchronous movement of the two support frames 4, thereby maintaining the symmetry of the two support frames 4 and facilitating blade installation.

[0036] Furthermore, a worm gear reducer is provided between the connecting rod 203 and the drive screw 204.

[0037] It should be understood that by setting up a worm gear reducer, the transmission structure is made into a unidirectional transmission, thus locking the sliding position of the support frame 4.

[0038] In some feasible ways, the support frame 4 is fixed on two first sleeves 401 and second sleeves 404. To facilitate the sliding of the first sleeves 401 and second sleeves 404, a support plate 305 is provided at the bottom of the slide rail plate 304. The support plate 305 has the same thickness as the bottom side of the first sleeves 401 and second sleeves 404.

[0039] The dual-output gearbox 202 can be a bevel gearbox, with a driven bevel gear meshing on each side of the driving bevel gear. The driven bevel gears are connected to the connecting rod 203, which is a cylindrical rod connected to the input end of the worm gear reducer.

[0040] As another specific embodiment of the wind turbine blade tooling provided in the application, the connecting plate 101 has two rows of pin holes 102 in a linear array, and the bearing frame 4 is provided with a sliding block 405 at the end away from the bearing platform 3. In use, the sliding block 405 is bolted to the pin holes 102.

[0041] Based on specific usage scenarios, by setting pin holes 102, after the support frame 4 slides to the appropriate position, the position is locked by bolts, thereby improving the stability during transportation.

[0042] In some feasible ways, the position of the pin hole 102 can be set according to the size of the blade that needs to be frequently moved.

[0043] As another specific embodiment of the wind turbine blade tooling provided in the application, the support frame 4 is fixedly installed with a displacement plate 407, and the displacement plate 407 is provided with several sets of displacement holes 408, and the side fixing plate 402 is bolted to one set of displacement holes 408.

[0044] It should be understood that by setting the shift plate 407 and the shift hole 408, the position of the side fixing plate 402 can be adjusted in order to better adapt to changes in the size of the blade.

[0045] In some feasible ways, the shift plate 407 is rectangular, the shift hole 408 can be set according to the size of the blade that needs to be transported frequently, and a U-shaped piece is fixedly connected to one side of the side fixing plate 402. The U-shaped piece has a through hole. During installation, the U-shaped piece is snapped onto the outside of the side fixing plate 402 and fixedly connected by bolts.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
