[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings.

It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0032] like Figures 1-3 As shown, this embodiment provides a wind turbine foundation tilt correction and leveling device, including a lifting mechanism 1, a support plate 2, and multiple leveling mechanisms 3. The lifting mechanism 1 is vertically arranged with its lifting end facing upward. The support plate 2 is arranged above the lifting mechanism 1, and the multiple leveling mechanisms 3 are distributed circumferentially between the lifting mechanism 1 and the support plate 2. The support plate 2 is connected to the lifting end of the lifting mechanism 1 through the multiple leveling mechanisms 3. The multiple leveling mechanisms 3 are used to jointly adjust the levelness of the support plate 2, and the lifting mechanism 1 is used to adjust the height of the support plate 2. In this way, the lifting mechanism can be vertically set on the ground, and the levelness of the support plate can be adjusted by multiple leveling mechanisms. At this time, when correcting the tilt of the wind turbine foundation, a jack can be placed on the support plate to ensure the verticality of the jack lifting operation. In addition, the lifting mechanism can also adjust the height of the support plate.

[0033] The lifting mechanism 1 described in the above technical solution includes a support base 11, a screw 12, and a support plate 13. The support base 11 is vertically arranged, and its upper end is vertically recessed with a threaded hole 111 that mates with the screw 12. The screw 12 passes through the threaded hole 111 to be threadedly connected to the support base 11. The support plate 13 is horizontally arranged above the screw 12. A plurality of leveling mechanisms 3 are arranged circumferentially at intervals on the upper end of the support plate 13. The screw 12 is rotated clockwise or counterclockwise to adjust the height of the support plate 13. Its structure is simple, and height adjustment is more convenient. It also has good load-bearing capacity. In this embodiment, the support plate constitutes the lifting end of the lifting mechanism.

[0034] The support base 11 described in the above technical solution has an outward flange 112 at its lower end, which makes the contact area between the lower end of the support base and the ground larger, thereby reducing the pressure on the ground.

[0035] The lifting mechanism 1 described in the above technical solution also includes a handle 113 provided on the side wall of the support base 11, which makes it more convenient to pick up and put down the entire wind turbine foundation tilt correction and leveling device.

[0036] The handle 113 is a "C" shaped handle, which is simple in structure. In the embodiment, the handle is vertically arranged and connected to the support seat at both ends (similar to the handle of a water cup).

[0037] The horizontal bubble 4 is arranged at the middle of the upper end of the support plate 2, so that the support plate can be observed to be adjusted to be horizontal through the horizontal bubble.

[0038] The leveling mechanism 3 is arranged in three, and the three leveling mechanisms 3 are evenly distributed along the ring direction between the jacking mechanism 1 and the support plate 2, so that the three leveling mechanisms jointly level the support plate, which is good in leveling effect and good in support effect on the support plate.

[0039] As shown in Figure 4 and Figure 5 The leveling mechanism 3 includes the height adjusting piece 31 and the universal ball 32. The universal ball 32 includes the ball body 321 and the ball seat 322. The ball body 321 is movably embedded in the ball seat 322. The height adjusting piece 31 is vertically arranged at the corresponding position of the jacking end of the jacking mechanism 1. The universal ball 32 is embedded at the corresponding position of the lower end of the support plate 2. The upper end of the height adjusting piece 31 is connected to the ball body 321 in the radial direction. The length of the height adjusting piece 31 is adjusted to adjust the height of the corresponding position of the support plate 2. The structure is simple. The height adjusting piece can finely adjust the height of the universal ball. The ball body provides the activity allowance for the height adjusting piece to swing relative to the support plate.

[0040] As shown in Figure 4 and Figure 5 The height adjusting piece 31 includes the connecting rod 311 and the handle plate 312. The jacking end of the jacking mechanism 1 is concavely arranged with a plurality of screw grooves 131 evenly spaced along the ring direction. The plurality of screw grooves 131 correspond to the plurality of height adjusting pieces 31 one by one. The handle plate 312 is horizontally arranged. The connecting rod 311 is vertically arranged and penetrates the middle of the handle plate 312. The connecting rod 311 and the handle plate 312 are fixedly connected. The connecting rod 311 is provided with external threads at the lower end of the handle plate 312, which are matched with the screw grooves 131. The lower end of the connecting rod 311 is threadedly connected to the screw grooves 131. The universal ball 32 is embedded at the corresponding position of the lower end of the support plate 2. The upper end of the connecting rod 311 is connected to the ball body 321 of the universal ball 32 in the radial direction. The handle plate 312 is twisted to adjust the height of the corresponding position of the support plate 2. The structure is simple. The height of the corresponding universal ball can be adjusted by forward or reverse rotation of the handle plate.

[0041] As shown in Figure 2As shown, the handle plate 312 in the above technical solution is a circular plate with friction texture on its edge. Its structure is simple and it is easier to operate when rotating. The edge of the handle plate protrudes outside the support plate, which makes it easier for the hand to rotate the handle plate.

[0042] In this embodiment, both the tray and the support plate are circular plates, and preferably, the tray and the support plate have the same diameter.

[0043] In this embodiment, the screw can be hollow inside, and the support base can also be cylindrical, which makes the entire wind turbine foundation tilt correction and leveling device lighter. In this embodiment, the diameter of the screw is smaller than the diameter of the support plate, and the support base, screw and support plate are coaxially distributed.

[0044] In this embodiment, the level bubble can be embedded in the middle of the upper end of the tray (the upper end of the level bubble is lower than the upper end of the tray, so as to avoid the jack from crushing and damaging the level bubble).

[0045] In this embodiment, the upper end of the tray is recessed with an oil injection hole 21 corresponding to the mounting position of each universal ball. In order to maintain the lubrication between the ball and the ball seat, lubricating oil can be added into the universal ball through the oil injection hole 21 (the upper end of the ball seat has an eyelet that communicates with the oil injection hole).

[0046] Preferred, such as Figure 6 As shown, the support plate has multiple handles 132 protruding evenly in a circumferential direction at its edge (specifically, four handles 132 can be provided on the support plate), which makes it easier for the support plate to drive the screw to rotate relative to the support base.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
