DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] 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.

[0020] According to Figures 1-5 As shown, a device for installing and adjusting the rotor orientation of a wind turbine generator set includes a main shaft 1 of an engine rotor. A brake disc 2 is fixedly installed on one side of the main shaft 1 of the engine rotor. Teeth are provided on the brake disc 2. The brake disc 2 is connected to a transmission column 9 through the cooperation of the teeth. Mounting plates 7 and fixing plates 5 are respectively arranged on both sides of the transmission column 9. The mounting plate 7 is L-shaped. One end of the transmission column 9 is rotatably installed with the vertical end of the mounting plate 7. The other end of the transmission column 9 is fixedly installed with an adjusting rod 10. The middle part of the adjusting rod 10 is rotatably installed on the fixing plate 5.

[0021] A protective frame 3 is fixedly installed on one side of the main shaft 1 of the engine rotor. An installation groove is provided at the bottom of the protective frame 3. The flat end of the mounting plate 7 is fixedly installed with the installation groove. Both the brake disc 2 and the transmission column 9 are installed in the protective frame 3. The fixing plate 5 is fixedly installed on the outer wall of the protective frame 3.

[0022] Two limiting holes 11 are provided at the top of the protective frame 3. A locking pin 4 is inserted into each limiting hole 11.

[0023] A plurality of mounting holes 8 are formed in the brake disc 2, and the mounting holes 8 are evenly distributed outside the axis of the brake disc 2.

[0024] One end of the locking pin 4 passes through the limiting hole 11 and is installed in the mounting hole 8.

[0025] One end of the adjusting rod 10 is provided with an adjusting groove 6. The adjusting rod 10 is cylindrical, and the adjusting groove 6 is rectangular.

[0026] Working principle: The main shaft brake disc 2 is connected to match the engine rotor main shaft 1. The outer ring of the main shaft brake disc 2 is designed with teeth to cooperate with the transmission column 9 for power transmission. When adjusting the engine rotor main shaft 1, control the transmission column 9 to rotate. The transmission column 9 drives the brake disc 2 to rotate, thereby driving the rotation of the engine rotor main shaft 1 to realize the adjustment of its orientation. After the adjustment is completed, insert the locking pin 4 into the mounting hole 8 to limit the rotation of the engine rotor main shaft 1, and realize the installation through the other end of the engine rotor main shaft 1.
