Description

Technical Field

[0001] This utility model belongs to the technical field of wind power generation equipment, specifically relating to a high-strength wind turbine tower flange support device. Background Technology

[0002] Wind turbine towers generally adopt a conical structure with flanges at both ends. Typically, the tower is manufactured in the factory, transported to its destination, and then assembled. Due to the large size of the flanges on the tower, they are prone to deformation due to bumps and vibrations during transportation. Existing technologies usually use flange support assemblies to support the flanges on the tower. For example, Chinese patent application number CN202020963569.9 mentions a wind turbine tower flange support device. This wind turbine tower flange support device achieves adjustable size of the support device through the adjustable connection between the flange connector 3 and the adjusting screw 2, thus giving the support device good versatility. However, the size adjustment of the above-mentioned wind turbine tower flange support device requires adjusting the position of multiple adjusting screws 2 one by one, which is cumbersome. Utility Model Content

[0003] The purpose of this utility model is to provide a high-strength wind turbine tower flange support device to solve the problem mentioned in the background art that requires adjusting the position of multiple adjusting screws one by one when adjusting the size, which is cumbersome.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-strength wind turbine tower flange support device, comprising a fixed plate, a gear ring rotatably connected to the top of the fixed plate, and an inner ring of a support frame fixed at the top of the fixed plate near the gear ring. An outer ring of a support frame is connected to the outer circumference of the inner ring of the support frame, and a gear is rotatably connected to the inner circumference of the inner ring of the support frame. An adjustment component is provided on the outer circumference of the outer ring of the support frame, the adjustment component comprising a screw and a screw sleeve, the screw sleeve being screwed into the screw, and the screw and the gear being connected via a rotating shaft.

[0005] Preferably, the gear meshes with a gear ring, and the number of gears is equal to the number of rotating shafts and the number of adjusting components.

[0006] Preferably, the rotating shaft passes through the inner ring and outer ring of the support frame in sequence.

[0007] Preferably, the end of the adjusting component away from the outer ring of the support frame is connected to a support component, the support component including an abutment piece and a flange connecting piece, the abutment piece and the flange connecting piece being integrally formed and arranged perpendicularly to each other.

[0008] Preferably, the end of the abutment piece away from the adjusting component is provided with an arc-shaped surface, and the flange connecting piece is provided with bolt holes that match the flange.

[0009] Preferably, the support component has an L-shaped structure.

[0010] Preferably, the bottom of the fixed disk is provided with a rotating handle, and the output end of the rotating handle is connected to the gear ring.

[0011] Preferably, the number of supporting components is equal to the number of adjusting components.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model is equipped with a gear structure and adjustment components. The gear ring drives multiple gears to rotate synchronously, thereby driving multiple screws to rotate synchronously, and then driving multiple screw sleeves to move synchronously. This enables multiple support components to move synchronously, thus supporting wind turbine tower flanges of different sizes. Since it does not require individual adjustment, it is convenient to use.

[0014] (2) The present invention is provided with an L-shaped support component, which abuts against the inner wall of the wind turbine tower through the abutment piece, and at the same time connects and fixes the flange connecting piece to the wind turbine tower flange, thereby improving the stability of the wind turbine tower flange support.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution: a high-strength wind turbine tower flange support device, including a fixed plate 1, a gear ring 2 rotatably connected to the top of the fixed plate 1, and a support frame inner ring 3 fixed at the top of the fixed plate 1 near the gear ring 2. The outer circumference of the support frame inner ring 3 is connected to a support frame outer ring 4, and a gear 5 is rotatably connected to the inner circumference of the support frame inner ring 3. An adjustment component is provided on the outer circumference of the support frame outer ring 4. The adjustment component includes a screw 6 and a screw sleeve 7. The screw sleeve 7 is screwed into the screw 6. The screw 6 and the gear 5 are connected by a rotating shaft 8, which passes through the support frame inner ring 3 and the support frame outer ring 4 in sequence.

[0022] like Figure 3 As shown, the inner wall of the threaded sleeve 7 is provided with a stop, which helps to prevent the screw 6 from disengaging from the threaded sleeve 7.

[0024] In the above technical solution, the gear ring 2 rotates to drive multiple gears 5 to rotate synchronously, and the multiple gears 5 rotate synchronously to drive multiple rotating shafts 8 to rotate synchronously, thereby driving multiple screws 6 to rotate synchronously. The multiple screws 6 rotate synchronously to drive multiple threaded sleeves 7 to move synchronously, which in turn drives multiple support components 9 to move synchronously, thereby achieving the support of wind turbine tower flanges of different sizes.

[0025] like Figure 4 As shown, the end of the adjusting component away from the outer ring 4 of the support frame is connected to the support component 9. The support component 9 has an L-shaped structure and includes an abutment piece 91 and a flange connecting piece 92. The abutment piece 91 and the flange connecting piece 92 are integrally formed and are perpendicular to each other. The end of the abutment piece 91 away from the adjusting component is provided with an arc-shaped surface to facilitate the abutment piece 91 to abut against the inner wall of the wind turbine tower. The flange connecting piece 92 is provided with bolt holes that match the flange.

[0026] In the above technical solution, during support, the abutment piece 91 abuts against the inner wall of the wind turbine tower, and the flange connecting piece 92 is fixedly connected to the wind turbine tower flange by bolts, which improves the stability of the support.

[0027] like Figure 2 As shown, a rotating handle 10 is provided at the bottom of the fixed disk 1, and the output end of the rotating handle 10 is connected to the gear ring 2; the rotating handle 10 facilitates the rotation of the gear ring 2, and can also be driven by a motor.
