With the continuous advancement of wind power technology, the clamping operation of wind turbine blades has become a critical link in the production, manufacturing, testing, transportation, and installation process, directly affecting the safety and operational efficiency of the blades.

[0003] Chinese Patent CN222124716U discloses a clamping device for fatigue testing of wind turbine blades, comprising: an external assembly, including a set of long steel frame components and a set of short steel frame components connected to the long steel frame components; this invention uses a crane to place the short steel frame components on the upper ends of both sides of the bottom long steel frame components, and then uses a crane to place the upper long steel frame components on the upper end of the wind turbine blade. After the upper long steel frame components are stably placed, they are connected by connecting components that sequentially pass through the upper long steel frame components, the short steel frame components, and the lower long steel frame components, thereby clamping and fixing the wind turbine blade in the middle position of a set of wooden clamps. However, when clamping and fixing the wind turbine blade using wooden clamps in the above patent, manual clamping is required, and there are limitations when clamping wind turbine blades of different specifications, making it difficult to adaptively adjust the clamping for different specifications of wind turbine blades, reducing the flexibility of clamping. Therefore, we propose an adaptive clamping device for wind turbine blades to solve the above problems. Utility Model Content

Two upper support plates 9 fixedly installed on the outer surface of the top seat 2. Two T-slots 5 are formed on the outer surface of both the top seat 2 and the outer surface of the base 1. Electric cylinders 6 are fixedly installed on the inner walls of the two sets of T-slots 5. Sliding plates 7 are fixedly installed on the telescopic ends of the two sets of electric cylinders 6. Clamping plates 12 are fixedly installed on the side of the two sets of sliding plates 7 that are close to each other. Two limiting components 4 are provided on top of the base 1. The base 1 and the top seat 2 can form an overall frame, while the lower support plates 8 and the upper support plates 9 can provide a mounting base for components such as the driving component 3. Through the cooperation of the T-slots 5 and the electric cylinders 6, the sliding plates 7 can be provided with a track and power for sliding, thereby driving the clamping plates 12 to achieve the clamping action of the wind turbine blade.

[0023] In a further embodiment, each of the two limiting members 4 includes two sliding blocks 401 and two sliding plates 402. The bottom surface and the upper surface of the two sliding plates 402 are fixedly installed on the side of the two sets of sliding plates 7 that are close to each other. The upper surface of each of the two sliding blocks 401 is provided with a sliding groove 403. The bottom end of each of the two sliding plates 402 extends into the interior of the two sliding grooves 403. The outer surface of each of the two sliding plates 402 is slidably connected to the inner wall of the two sliding grooves 403. Through the sliding cooperation of the sliding plates 402 in the sliding grooves 403, stable guidance and limiting can be provided for the sliding plates 7 during movement, preventing the sliding plates 7 from deviating or shaking during movement, and ensuring that the clamping plate 12 can accurately and stably clamp the wind turbine blades.

[0024] In a further embodiment, each of the two driving components 3 includes a driving cover 301 fixedly mounted on the upper surface of the lower support plate 8. A lifting cover 302 is slidably connected to the inner wall of each of the two driving covers 301. The top ends of the two lifting covers 302 are fixedly mounted to the bottom surfaces of the two upper support plates 9, respectively. A threaded lifting plate 304 is fixedly mounted on the inner wall of each of the two lifting covers 302. A threaded transmission rod 303 is threadedly connected to the inner wall of each of the two threaded lifting plates 304. A forward and reverse motor 305 is fixedly mounted on the upper surface of each of the two lower support plates 8. The output ends of the two forward and reverse motors 305 are fixedly mounted to the bottom ends of the two threaded transmission rods 303, respectively. Two upper lifting components 13 are fixedly mounted on the outer surface of each of the two upper support plates 9, and two lower lifting components 10 are fixedly mounted on the outer surface of each of the two lower support plates 8. A synchronous controller 11 is fixedly mounted on the upper surface of the top seat 2. Through the forward and reverse motors... The operation of the reverse motor 305 drives the threaded transmission rod 303 to rotate. Through the threaded lifting plate 304, the lifting cover 302 can slide within the drive cover 301, realizing the height adjustment between the top seat 2 and the base 1 to accommodate wind turbine blades of different heights. The upper lifting component 13 and the lower lifting component 10 are set to connect the lifting equipment to realize the lifting of wind turbine blades. The synchronous controller 11 coordinates and controls each drive component. The synchronous controller 11 can convert the processed instructions into control signals and send them to the drive circuit of the electric cylinder 6 and the frequency converter of the forward and reverse motor 305, etc. The drive circuit controls the extension and retraction of the electric cylinder 6 according to the received signals, and the frequency converter adjusts the speed and direction of the forward and reverse motor 305, thereby realizing the coordinated action of each component and ensuring the stability and accuracy of the entire device during operation.

[0025] The working principle of this utility model is as follows: First, according to the width of the wind turbine blade, the electric cylinder 6 is started. The electric cylinder 6 can push the sliding plate 7 to slide in the T-slot 5, and the sliding plate 7 will drive the clamping plate 12 to move, thereby adjusting the distance between the two clamping plates 12 to match the width of the wind turbine blade. Then, one end of the wind turbine blade is inserted between the two sets of clamping plates 12. Next, the forward and reverse motor 305 is started to run. The forward and reverse motor 305 drives the threaded transmission rod 303 to rotate, which enables the threaded lifting plate 304 to be threadedly connected to the threaded transmission rod 303. Under the action of threaded transmission, the threaded lifting plate 304 drives the lifting cover 302 to slide downward inside the drive cover 301, thereby enabling the two clamping plates 12 above to clamp and fix the wind turbine blade. Then, through the upper lifting component 13 and the lower lifting component 10, the device is conveniently connected to the lifting equipment to realize the lifting of the wind turbine blade.
