The annular tube 41 and the cylinder barrel 42 are filled with hydraulic oil.

[0031] The present invention and its advantages: When the tooling for assembling and positioning the blades of a wind turbine generator is used, the working process is as follows:

[0032] like Figure 1 , Figure 2 and Figure 3As shown, the upper half of the blade is fixed on the fixing frame 9, and the pressure plate 11 and the pressure plate 2 12 are respectively fixed on the two protruding rods 10 by bolt assemblies or other conventional adjustable fixing components, and the bottom surfaces of the pressure plates 11 and 12 are flush with the bottom surfaces of the ends of the upper half of the blade, and the slide cylinder 13 and the slide cylinder 2 14 are respectively fixed at the two ends of the lower half of the blade by bolts, and the upper end surfaces of the slide cylinder 13 and the slide cylinder 2 14 are flush with the upper surface of the end of the lower half of the blade, and the winch 5 is controlled by the controller. The lifting cable 8 is reeled in to lift the fixing frame 9 and the upper half of the blade, and then the position of the hanging plate 6 is controlled and adjusted by driving motor 1 and driving motor 2, so that the positioning hole on the protruding rod 10 corresponds to the corresponding positioning rod 15, and the lifting cable 8 is unreeled by the winch 5, so that the fixing frame 9 and the protruding rod 10 are moved downward, and the positioning rod 15 is inserted into the positioning hole, so that the fixing frame 9 and the upper half of the blade can only move up and down, thereby avoiding the shaking of the blade during the splicing process and improving the stability of the blade during the splicing process.

[0033] like Figure 3 , Figure 4 and Figure 5 As shown, during the downward movement of the fixing frame 9 and the upper half of the blade, when the pressure plate 1 11 and the pressure plate 2 12 are in contact with the corresponding slide rod 20 at the same time, the downward pressure on the two slide rods 20 is the same, and then the slide rod 20 exerts the same pressure on the hydraulic oil in the corresponding cylinder 22 through the piston plate 3 36, that is, the opposite pressures received by the two piston plates 1 32 are the same and offset each other, so that the spring 1 27 does not contact with the touch switch 1 28, and the spring 2 24 does not contact with the touch switch 2 23. The controller controls the adjustment motor not to work, and there is no need to adjust the lower half of the blade. At this time, the upper half of the blade is in a parallel state with the upper half of the blade, thereby realizing the matching assembly of the blades.

[0034] When the pressure plate 11 first contacts the corresponding slide rod 20, it means that the left end of the lower half of the blade is higher, and the slide rod 20 in the slide barrel 13 applies a greater pressure to the hydraulic oil in the left cylinder barrel 22 through the piston plate 36, so that the piston plate 32 in the left cylinder barrel 22 moves to the right, and drives the spring 27 to contact and pressurize the touch switch 28 through the piston rod 31 and the connecting rod 25. The touch switch 28 transmits the touch signal of the spring 27 to the controller, and the controller controls the adjustment motor 2 9 works, so that the regulating motor 29 drives the active roller 30 to rotate counterclockwise through the worm gear assembly 26, so that the active roller 30 drives the lower half of the blade to rotate counterclockwise, so that the left end of the lower half of the blade is lowered and the right end is raised. When the hydraulic oil pressures in the two cylinder barrels 1 22 are the same, that is, the spring 1 27 does not contact with the touch switch 1 28, and the spring 24 does not contact with the touch switch 2 23, the upper half of the blade is in parallel with the upper half of the blade, so that the blades are assembled together.

[0035] When the pressure plate 12 first comes into contact with the corresponding slide bar 20, as mentioned above, the controller controls the adjusting motor 29 to drive the active roller 30 to rotate clockwise, thereby realizing automatic detection and automatic adjustment of the blades during assembly, without the need for multiple manual adjustment operations, saving time and effort and improving the assembly efficiency of the blades.

[0036] like Figure 6 and Figure 7 As shown, during the hoisting process of the upper half of the blade, when the release speed of the suspension cable 8 is relatively low, the guide wheel 50 and the gear ring 49 drive the toothed disc 56 to rotate, so that the toothed disc 56 drives the turntable 39 to rotate synchronously through the pipe shaft 55, and then the turntable 39 synchronously drives the annular tube 41 and the cylinder barrel 42 to rotate. Since the rotation speed of the turntable 39 is relatively low, the centrifugal force on the counterweight rod 53 is relatively small, so that the hydraulic oil in the annular tube 41 cannot be pushed into the conduit 1 43, and the push rod 44 cannot push the fan-shaped block 47 to contact with the suspension cable 8 through the spring 5 46, thereby not affecting the operation of the suspension cable 8.

[0037] When the suspension cable 8 breaks, the suspension cable 8 is accelerated under the gravity of the fixing frame 9 and the upper half of the blade, so that the suspension cable 8 drives the toothed disc 56 to rotate rapidly through the guide wheel 50 and the gear ring 49, so that the toothed disc 56 drives the rotating disc 39 to rotate rapidly synchronously through the pipe shaft 55, and then the rotating disc 39 drives the annular tube 41 and the second cylinder 42 to rotate rapidly synchronously, so that the centrifugal force on the counterweight rod 53 increases and moves away from the pipe shaft 55 under the action of the centrifugal force, and the hydraulic oil in the annular tube 41 is pressurized, so that the hydraulic pressure in the annular tube 41 enters the second cylinder 42 through the liquid pipe 40. The inner part of the tube shaft 55 and the liquid pipe three 58 enter the conduit one 43, so that the push rod 44 pushes the fan-shaped block 47 to contact with the suspension cable 8 through the spring five 46, and the fan-shaped block 47 is made to move continuously toward the suspension cable 8 at the end away from the rotation center under the friction of the suspension cable 8, and presses the suspension cable 8 to stop, thereby realizing the anti-falling effect of the suspension cable 8. On the one hand, it avoids the danger of the upper half of the blade falling during the blade assembly process, and on the other hand, it protects the upper half of the blade to avoid damage, thereby improving the safety of the blade assembly process.

[0038] As described above, during the movement of the push rod 44, when the slot on the push rod 44 corresponds to the block 45, the block 52 is inserted into the slot under the action of spring six 52, so that the push rod 44 remains fixed, ensuring that the push rod 44 applies a stable pushing force to the fan-shaped block 47 through spring five 46, thereby ensuring the squeezing and stopping effect on the suspension cable 8.

[0039] The two symmetrical fan-shaped blocks 47 are designed so that the suspension cable 8 can be stopped when falling, whether it moves up or down.

[0040] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
