A plurality of outer wall contact components 3 are provided inside the limiting ring 2. The outer wall contact components 3 include a telescopic rod 31 and a retaining ring 33. A limit head 32 is fixedly connected to the front end of the telescopic rod 31, and the telescopic rod 31 is slidably connected to the limiting ring 2.

[0021] In this implementation scheme: a segmented column 11 is provided below the dedicated rod 1, and connecting columns 12 are fixedly connected to both ends of the segmented column 11. A first adjusting ball 13 and a second adjusting ball 14 for adjusting the angle of the limiting ring 2 are fixedly connected to the two connecting columns 12 respectively. When limiting the position of the wind turbine anchor bolt, the limiting ring 2 is fitted onto the outside of the head end of the wind turbine anchor bolt. The angle of the dedicated rod 1 can be adjusted according to the position of use, making it convenient for personnel to hold the dedicated rod 1. The two connecting columns 12 can change their angles under the action of the adjusting balls, making the angle change range wide. Under the adjustment action of the first adjusting ball 13 and the second adjusting ball 14, the angle is adjusted by cooperating with the ball groove. After adjustment, the position of the adjusting ball can be limited by fasteners 15, which can be bolts. One end of the device abuts against the outer wall of the adjusting ball. The outer wall contact component 3 includes a telescopic rod 31 and a retaining ring 33. The front end of the telescopic rod 31 is fixedly connected to a limiting head 32. The telescopic rod 31 is slidably connected to the limiting ring 2. At the same time, multiple limiting heads 32 can block the position of the wind power anchor bolt head, which can clamp the wind power anchor bolt head inside the limiting ring 2, thereby improving the tightness of the limiting position, improving the stability of the wind power anchor bolt, and facilitating the operation of the wind power anchor bolt using the special rod 1. When the wind power anchor bolt head is placed inside the limiting ring 2, it will squeeze the limiting head 32, causing the retaining ring 33 to compress the spring 34 in the inner groove 21. This provides a limiting force to the wind power anchor bolt head through the telescopic rod 31, so that the wind power anchor bolt head is located inside the limiting ring 2.

[0022] The first adjusting ball 13 is movably connected to the segmented column 11, and the second adjusting ball 14 is movably connected to the special rod 1. Both the special rod 1 and the segmented column 11 are provided with fasteners 15 on their outer sides to limit the rotation of the first adjusting ball 13 and the second adjusting ball 14. Under the adjustment action of the first adjusting ball 13 and the second adjusting ball 14, the angle can be adjusted by cooperating with the ball groove. After adjustment, the position of the adjusting ball can be limited by the fasteners 15. The fasteners 15 can be bolts, which are threadedly connected to the special rod 1 and the segmented column 11, with one end abutting against the outer wall of the adjusting ball.

[0023] The limiting ring 2 is fixedly connected to one of the connecting posts 12. The limiting ring 2 has an opening to avoid the head of the wind turbine anchor bolt. The opening makes it easy to fit into the head of the wind turbine anchor bolt and to remove it.

[0024] A rubber pad is fixedly connected to the outside of the limiting head 32, and a retaining ring 33 is fixedly connected to the outside of the limiting head 32. When the limiting head 32 contacts the end of the wind turbine anchor bolt, the rubber pad can protect the surface of the end of the wind turbine anchor bolt, and at the same time, friction can be applied to further stabilize the end of the wind turbine anchor bolt within the limiting ring 2.

The retaining ring 33 is slidably connected in the inner groove 21. When the wind turbine anchor bolt head is placed in the limiting ring 2, it will squeeze the limiting head 32, causing the retaining ring 33 to compress the spring 34 in the inner groove 21 and move, thereby providing a limiting force to the wind turbine anchor bolt head through the telescopic rod 31.

[0026] The working principle and usage process of this utility model are as follows: The limiting ring 2 is fitted onto the outer side of the wind turbine anchor head. The angle of the special rod 1 can be adjusted according to the usage position, making it easy for personnel to hold the special rod 1. The two connecting columns 12 can change their angles under the action of the adjusting balls, resulting in a wide range of angle changes.

After adjustment, the position of the adjusting ball can be limited by the fastener 15. The fastener 15 can be a bolt, with one end abutting against the outer wall of the adjusting ball. The outer wall contact assembly 3 includes a telescopic rod 31 and a retaining ring 33. The telescopic rod 31 is positioned in front of... The end is fixedly connected to the limiting head 32, and the telescopic rod 31 is slidably connected to the limiting ring 2. At the same time, multiple limiting heads 32 can block the position of the wind power anchor bolt head, which can clamp the wind power anchor bolt head inside the limiting ring 2, thereby improving the tightness of the limiting position, improving the stability of the wind power anchor bolt, and facilitating the operation of the wind power anchor bolt with the special rod 1. When the wind power anchor bolt head is placed inside the limiting ring 2, it will squeeze the limiting head 32, causing the retaining ring 33 to compress the spring 34 in the inner groove 21, thereby providing the limiting force to the wind power anchor bolt head through the telescopic rod 31, so that the wind power anchor bolt head is located inside the limiting ring 2.
