The first pre-pressure plate 150 corresponds one-to-one with the first positioning plate 310.

[0025] Furthermore, the first rotating assembly includes a first support plate 210 and a first rotating plate 220. The first support plate 210 is disposed at the lower end of the first alignment frame 200, and the first rotating plate 220 is rotatably disposed at the upper end of the first support plate 210. The two ends of the first support plate 210 are provided with a plurality of first adjusting blocks 290, and the upper end of the first adjusting block 290 is provided with a first fixing screw 291, which matches the first rotating plate 220.

[0026] Furthermore, the first propulsion assembly is disposed on the first rotating plate 220. The first propulsion assembly includes a front and rear propulsion electric cylinder 230 and a front and rear limiting electric cylinder 270. The first rotating plate 220 is provided with a first limiting frame 240 at both ends. The first limiting frame 240 is provided with a first limiting plate 250. The front and rear propulsion electric cylinder 230 is disposed at both ends of the first rotating plate 220 and is connected to the first limiting plate 250. The upper end of the first limiting plate 250 is provided with a first mounting seat 260. The lower end of the blade root prefabricated flange 300 is provided with a second positioning plate 320. The lower end of the second positioning plate 320 is provided with a first positioning hole 261. The front and rear limiting electric cylinder 270 is disposed on the first mounting seat 260. The front and rear limiting electric cylinder 270 is provided with a first push rod. The first push rod corresponds one-to-one with the first positioning hole 261.

[0027] Furthermore, the rotating assembly includes a plurality of first rollers 280, which are disposed at the lower end of the first rotating plate 220.

[0028] Working principle: Several calibration points are set on the blade root prefabrication flange 300, and several high-precision displacement sensors 120 are set on the wind turbine blade root mold 110. The blade root prefabrication flange 300 is moved to the wind turbine blade root mold 110 by a hoisting device, so that each of the high-precision displacement sensors 120 corresponds to a calibration point. Among them, two of the six high-precision displacement sensors 120 are set on both sides of the upper end of the first mounting frame 100, corresponding to the upper end of the blade root prefabrication flange 300, and the other four are distributed between the first two high-precision displacement sensors 120. The blade root prefabrication flange 300 is hoisted to the wind turbine blade root mold 110 by a hoisting device, and the high-precision displacement sensors 120 correspond one-to-one with the calibration points. First, the second positioning plate 320 is moved onto the first mounting base 260. Then, the first push rod is pushed into the first positioning block by the front and rear limit electric cylinders 270 to position and install the second positioning plate 320 and the blade root prefabricated flange 300. At the same time, the first positioning plate 310 is placed on the first pre-pressure plate 150 to initially position the blade root prefabricated flange 300.

[0029] The installation positions corresponding to each calibration point are pre-calibrated and marked using a three-coordinate system. A high-precision displacement sensor 120 determines the angle and distance values ​​of each calibration point and marks them using a three-coordinate system, feeding back and saving the real-time position of the blade root prefabricated flange 300. By pre-setting the installation positions of six calibration points, the position of the blade root prefabricated flange 300 can be confirmed and marked using a three-coordinate system. The high-precision displacement sensor 120 can detect the angle and distance values ​​of its corresponding calibration points (i.e., the distance of the blade root prefabricated flange 300 can be determined by a single high-precision displacement sensor 120; the distance of the blade root prefabricated flange 300 can be determined by a combination of high-precision displacement sensors 120; the position of the blade root prefabricated flange 300 can be determined by controlling the distance and angle), and the actual position of the blade root prefabricated flange 300 is obtained by marking it using a three-coordinate system.

[0030] Based on the three-coordinate system of the real-time position of each calibration point and the three-coordinate system of the calibration position of the blade root prefabricated flange 300, the required adjustment angle and distance values ​​for each calibration point are calculated. The blade root prefabricated flange 300 is adjusted by the left and right pre-pressure electric cylinders 140 and the front and rear push electric cylinders 230. Based on the three-coordinate system of the actual position of the blade root prefabricated flange 300 and the preset installation position, the required adjustment position and angle of each calibration point of the blade root prefabricated flange 300 are confirmed. Then, the left and right pre-pressure electric cylinders 140 pull the first pre-pressure plate 150 to the left, tightening the upper sides of the blade root prefabricated flange 300. The first drive unit rotates the first push plate to abut against the blade root prefabricated flange 300, and the front and rear push electric cylinders 230 push the first limit plate 250 to the left to press the blade root prefabricated flange 300. At the same time, adjusting the first fixing screw 291 allows the first rotating plate 220 to be rotated and fixed in a suitable position. The tilt angle of the blade root prefabricated flange 300 in the vertical direction can be adjusted by the left and right pre-pressurization electric cylinders 140 and the front and rear propulsion electric cylinders 230, and the tilt angle of the blade root prefabricated flange 300 in the front and rear direction can be adjusted by adjusting the first rotating plate 220. The blade root prefabricated flange 300 is moved to the left as a whole by the left and right pre-pressurization electric cylinders 140 and the front and rear propulsion electric cylinders 230, and the blade root prefabricated flange 300 is precisely fixed.

[0031] After the prefabricated flange 300 is fixed in place, the production of the wind turbine blade root begins. The prefabricated flange 300 is calibrated periodically using the left and right pre-pressure electric cylinders 140 and the front and rear advance electric cylinders 230 until the wind turbine blade root production is complete. During production, the prefabricated flange 300 may experience slight displacement changes due to pressure. Therefore, the prefabricated flange 300 is recalibrated periodically during production, and its position is monitored and adjusted using a high-precision displacement sensor 120 to ensure that the position of the prefabricated flange 300 always meets the requirements.

[0032] It is worth mentioning that the technical features of the high-precision displacement sensor 120 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the utility model point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0033] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
