AI Technical Summary
Existing technologies cannot effectively prevent lateral displacement of yaw bearings when fixing them, resulting in unstable movement of the yaw bearings when tightening bolts.
The system employs an anti-shift structure and an adaptive structure. The anti-shift structure prevents the yaw bearing from moving left or right through the cooperation of a push plate, clamping block, and servo electric cylinder. The adaptive structure adjusts the orientation of the top surface of the yaw bearing to achieve alignment and tightening through a combination of a magnetic suction plate and a movable plate.
It effectively prevents the yaw bearing from moving during bolt tightening, improves the fixing effect, expands the working range, and ensures the stability and efficiency of tightening.

The following embodiments are used to illustrate this utility model.
[0028] like Figure 1 and Figure 2 As shown, a wind turbine bolt fastening device includes: a base 20, which is a rectangular plate with legs installed at the bottom; a mechanical combination arm 21 is fixedly connected to the top of the base 20; a tightening gun 22 is fixedly connected to the end of the mechanical combination arm 21; the tightening gun 22 is of the same model as the structure of the same name used in the prior art (publication number: CN214444434U); the mechanical combination arm 21 is the combined structure of the mechanical arm in the prior art; the mechanical combination arm 21 and the tightening gun 22 are electrically connected to the power supply, which is the prior art, so it will not be described in detail here.
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an anti-slip structure is installed on the top of the base 20 to prevent wind power components from moving. The anti-slip structure includes a push plate 31, a fixed frame 34, and a clamping block 36. The push plate 31 is movably connected to the top of the front wall of the base 20, the fixed frame 34 is fixedly connected to the top of the front wall of the base 20, and the clamping block 36 is movably connected to the wall of the fixed frame 34. The push plate 31 is located directly in front of the clamping block 36. The push plate 31, together with the clamping block 36, can prevent the wind power components from moving.
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the push plate 31 is a rectangular plate, and the lower half of the rear wall of the push plate 31 is wavy. The fixed frame 34 is a U-shaped frame with the opening facing downwards. The clamping block 36 is located in the opening of the fixed frame 34. The clamping block 36 is a V-shaped block with the opening facing forward. The front end of the clamping block 36 is arc-shaped. The anti-slip structure also includes a servo cylinder 30, an adapter 32, a rotating plate 33, and a fixed column 35. The servo cylinder 30 is fixedly connected to one side of the top of the base 20. One side of the rear wall of the push plate 31 can be fixedly connected to the front end of the servo cylinder 30. The adapter 32 is rotatably connected to the push plate 30. 1. The upper half of the front wall surface, the rotating plate 33 is fixedly connected to the rear end of the adapter 32, the fixed column 35 is fixedly connected to the cavity of the fixed frame 34, the retraction end of the servo electric cylinder 30 is connected to the push plate 31, the adapter 32 is composed of a cylinder in the rear half and a disk in the front half, the cylinder of the adapter 32 can be inserted into the wall surface of the push plate 31, the rotating plate 33 is located on the rear wall surface of the push plate 31, the rotating plate 33 is a semi-capsule-shaped plate, the fixed column 35 is cylindrical, the fixed column 35 can be inserted into the wall surface of the clamping block 36 from the top behind the clamping block 36, the clamping block 36 can move in the opening of the fixed frame 34;
[0031] In practical use, first turn on the power of the servo cylinder 30 and control it to extend to its maximum extent. At this time, the distance between the push plate 31 and the clamping block 36 will reach its maximum. Then, place the yaw bearing with the bolt to be tightened above the hinge plate 40. Next, control the servo cylinder 30 to retract, so that the servo cylinder 30 drives the push plate 31 and the rotating plate 33 to cooperate with the clamping block 36 to clamp the yaw bearing in the distance. At this time, the clamping block 36 will swing around the fixed column 35 as the center, automatically adapting to the yaw axis. When the push plate 31 moves toward the yaw bearing, the rotating plate 33 can be moved upward to a vertical position with the adapter 32 as the center, thereby expanding the contact area with the yaw bearing. At this time, the power of the mechanical combination arm 21 and the tightening gun 22 can be controlled to tighten the bolts on the yaw bearing one by one. After tightening, the servo cylinder 30 is extended to drive the push plate 31 to remove the clamp on the yaw bearing, thereby removing the yaw bearing and replacing it with the next yaw bearing to be tightened.
[0032] In summary, by setting up an anti-shift structure to clamp the yaw bearing from the side, the problem of the yaw bearing moving when tightening the bolts is effectively prevented. Compared with the existing technology, this solution has a better effect on fixing the yaw bearing.
[0033] like Figure 4 and Figure 5As shown, the wall of the base 20 is also provided with an adaptive structure, which includes: a straight rail 37, a magnetic plate 38, a front plate 39, and a hinged plate 40. The straight rail 37 is fixedly connected to the top side of the base 20, the magnetic plate 38 is slidably connected to the wall of the straight rail 37, the front plate 39 is fixedly connected to the front wall of the base 20, and the hinged plate 40 is rotatably connected to the front wall of the front plate 39. The straight rail 37 is a rectangular frame, the magnetic plate 38 can slide up and down along the cavity of the straight rail 37, the side wall of the magnetic plate 38 has an opening that can engage with the cavity of the straight rail 37, the magnetic plate 38 is made of magnetic material, the hinged plate 40 is a rectangular plate, and the rear wall of the hinged plate 40 is equipped with bolts that can be inserted into the wall of the front plate 39.
[0034] In practical use, when the yaw bearing is placed on the top of the flap 40, if the bolt position on the yaw bearing is on the inclined surface, the rotation of the flap 40 can be adjusted to adjust the angle of the yaw bearing on the flap 40, so that the bolt on the yaw bearing is aligned with the tightening gun 22. After the top surface of the yaw bearing is adjusted, the flat surface at the bottom of the magnetic plate 38 will be attracted to the top surface of the yaw bearing.
[0035] In summary, by setting an adaptive structure and adjusting the orientation angle of the top surface of the yaw bearing, the bolts on the yaw bearing wall can be aligned and tightened even when they are on an inclined surface, effectively improving the working range of this solution.
[0036] Working principle: First, turn on the power of the servo cylinder 30 and extend it to its maximum extent. At this time, the distance between the push plate 31 and the clamping block 36 will reach its maximum. Then, place the yaw bearing with the bolt to be tightened above the hinge plate 40. Then, control the servo cylinder 30 to retract, so that the servo cylinder 30 drives the push plate 31 and the rotating plate 33 to cooperate with the clamping block 36 to clamp the yaw bearing in the distance. At this time, the clamping block 36 will swing around the fixed column 35 as the center, automatically adapting to the surface of the yaw bearing. When the push plate 31 moves toward the yaw bearing, the rotating plate 33 can be moved upward to a vertical state with the adapter 32 as the center, thereby expanding the contact area with the yaw bearing. At this time, the power of the mechanical combination arm 21 and the tightening gun 22 can be turned on to tighten the bolts on the yaw bearing one by one.
