[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0016] According to Figure 1-2 As shown, an alignment bracket for installing two sets of blades of a wind turbine includes a base 1. A lifting assembly is provided below the base 1. Motors 2 are installed on both the left and right sides of the upper surface of the base 1. The output shaft of the motor 2 is connected to the speed reducer 8. A transmission assembly is provided on one side of the speed reducer 8. The rotating assembly includes a transmission shaft 9, a transmission wheel 3, and a transmission seat. The transmission seat is fixedly installed on the base 1. The transmission shaft 9 is rotatably installed on the rotating seat 10. Two transmission wheels 3 are fixedly installed on the transmission shaft 9. One end of the transmission shaft 9 passes through the transmission seat and is fixedly connected to the speed reducer 8.

[0017] The transmission wheels 3 on the two transmission assemblies rotate in the same direction.

[0018] The lifting assembly includes a threaded cylinder 4 and a support rod. The top of the threaded cylinder 4 is connected to the base 1. The bottom of the threaded cylinder 4 is screwed together with the top of the support rod.

[0019] A guide wheel 5 is installed at the bottom of each support rod. A brake 7 is provided behind the guide wheel 5.

[0020] A guide seat 6 is provided below the base 1. A guide groove is formed on the guide seat 6. The guide wheel 5 is fitted and installed in the guide groove

[0021] Working principle: During the blade installation process, first manually adjust the threaded cylinder 4 to adjust the support rod, thereby adjusting the center height of the blade. Then, hoist the blade above the base 1. The root of the blade is placed between the two transmission wheels 3. Both of the two transmission wheels 3 are rubber wheels with extremely large friction. Subsequently, the operator drives the transmission wheel 3 to rotate by adjusting the rotation direction of the motor 2. The transmission wheel 3 drives the blade root to rotate, thereby finely adjusting the blade angle. During the adjustment process, the operator can flexibly adjust the attitude of the blade according to the actual situation and installation requirements until the optimal installation position is reached.
