[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-3 As shown, a wind power flange drilling auxiliary positioning device includes a flange ring 1, a fixed part 11 is slidably provided on the flange ring 1, a movable part 12 is slidably provided on the fixed part 11, a plurality of shafts 131 arranged in a linear array are provided at the connection between the movable part 12 and the fixed part 11 and the flange ring 1, a plurality of guide rollers 13 arranged in a linear array are rotatably provided on the shafts 131, an extension rod 16 is provided on one of the shafts 131, an observation disk 17 is provided on the extension rod 16, and an observation block 18 fixedly connected to the extension rod 16 is provided in the observation disk 17.

[0023] Specifically, when in use, the movable part 12 is installed on the side of the fixed part 11, and then the shafts 131 on the movable part 12 and the fixed part 11 and the guide rollers 13 are respectively contacted with the inner and outer sides of the flange ring 1, so that the movable part 12 and the fixed part 11 slide on the flange ring 1. While sliding, the rotation of one of the shafts 131 will drive the observation block 18 on the observation disk 17, and the number of rotations of the observation block 18 is observed to determine the moving distance and mark it.

[0024] In the above scheme, the fixed part 11 and the movable part 12 on the flange ring 1 move on the flange ring 1, and a moving mark is made on the flange ring 1. The fixed part 11 and the movable part 12 are moved on the flange ring 1 through the extension rod 16 on the movable part 12 and the fixed part 11, and the guide roller 13 on the extension rod 16. The moving distance of the fixed part 11 and the movable part 12 on the flange ring 1 is achieved through the observation disk 17 on the extension rod 16.
