[0017] Reference Figure 1-Figure 3 A wind power yaw clamp replacement auxiliary device, which consists of: a support platform 2, an adjustment frame 5, a frame plate 3 and a platform plate 9, four guide rods 4 are fixed on the platform plate, and the guide rods pass through the round holes of the adjustment frame and the frame plate and are threadedly connected with nuts, a hydraulic cylinder 6 is fixed on the platform plate, and the push rod of the hydraulic cylinder is fixed on the bottom of the adjustment frame, and a fine-tuner 8 for adjusting the support platform is fixed in the adjustment frame, and multiple plug rods 1 are fixed on the support platform, and the plug rods are cylindrical rods, a total of four.

[0018] The wind turbine yaw clamp replacement auxiliary device comprises two support plates 21 arranged in parallel, the two support plates are connected and fixed by two U-shaped frames 22, the two U-shaped frames are arranged in parallel, and the U-shaped frames are welded to the support plates, and two plug rods are welded to each support plate.

[0019] The wind power yaw clamp replacement auxiliary device, the fine-tuner includes a screw rod 83, a screw sleeve 85 and a tile ring 82. The upper and lower ends of the screw rod are connected to the adjustment frame through bearings. The screw sleeve is sleeved on the screw and is threadedly connected to the screw. The tile ring is connected to the screw sleeve through a bearing. A handrail 84 is welded on the outer ring surface of the screw sleeve. Four vertical poles are fixed on the tile ring. Each of the vertical poles passes through the circular hole of the adjustment frame and is fixed to the frame plate.

[0020] Working principle: Refer to Figure 4-Figure 6 After all the remaining bolts of the yaw clamp are removed, the hydraulic cylinder push rod is retracted to lower the yaw clamp position, thereby realizing the disassembly of the yaw clamp. After removing the yaw clamp, the screw sleeve is rotated to lower the height of the frame plate to fall on the adjusting frame.

[0021] When installing the yaw clamp, place the yaw clamp on the device so that its four insertion rods are inserted into the four screw holes, and then adjust the hydraulic cylinder to raise its height until it is about to rise to the installation position. Universal wheels 7 are installed at the four corners of the bottom of the platform plate, which can be used to push and adjust the position of the device. After adjusting the position of the device to reach the installation position of the yaw clamp, turn the screw sleeve to raise the height of the frame plate, drive the yaw clamp to be raised in height until it is lifted to the installation position, and then install the bolts in the screw holes of the yaw clamp except the screw holes for inserting the insertion rods. After the installation is completed, retract the push rod of the device hydraulic cylinder to lower its height until the insertion rod exits the screw hole, and then install the bolts in the remaining four screw holes.
