Description

Technical Field

[0001] The invention relates to the technical field of wind power towers, and in particular to a rotary flange fixing plate of a wind power tower. Background Art

[0002] In the field of wind power generation, a wind turbine tower is a large structure formed by connecting multiple tower units through flanges, which can be used to support the upper impeller and generator set. As the power of wind turbines increases, the diameter of the impellers also increases, and the height of the corresponding towers increases and the cross-sectional dimensions also increase. In order to meet transportation requirements, large-diameter towers are usually processed in pieces.

[0003] The tower is segmented horizontally. If the support point is set below the tower, the support point below the tower is not conducive to anti-corrosion spraying on the surface of the tower. Therefore, a false flange device needs to be set at both ends of the tower. The existing false flange device is a circular structure plate. The flanges at both ends of the tower are fixed on the plate by bolts. It is difficult for the tower to find the cutting starting point during the segmentation cutting overshoot. At the same time, the cutting overshoot will cause damage to the plate, affecting its support stability. Summary of the invention

[0004] The object of the present invention is to provide a wind power tower rotating flange fixing plate to solve one or more of the above-mentioned prior art problems.

[0005] According to the present invention, a wind power tower rotating flange fixing plate includes a center ring, an outer support ring and a positioning mechanism. The center ring is concentrically arranged with the outer support ring and is connected through multiple groups of arc rods and arch frames. Flange connecting seats are symmetrically arranged on both sides of the arch frame, and multiple groups of the positioning mechanisms are arranged at the inner end of the outer support ring.

[0006] In some embodiments, the outer support ring includes an outer ring and an inner rotating ring, wherein the inner rotating ring is provided with slide grooves on both sides, the inner ends of the outer ring are provided with sleeve plates on both sides, and the inner wall of the sleeve plates is provided with a clamping ring, and the sleeve plates are sleeved on the outer layer of the inner rotating ring and are clamped with the slide grooves through the clamping ring.

[0007] In some embodiments, a plurality of balls are disposed between the outer ring and the inner rotating ring.

[0008] In some embodiments, the positioning mechanism includes a positioning seat and a U-shaped stopper, the inner end of the inner swivel is fixedly connected with the positioning seat, the outer layer of the sleeve plate is provided with a U-shaped stopper, and the positioning seat corresponds to the position of the U-shaped stopper.

[0009] In some embodiments, a positioning screw hole is provided at a side end of the positioning seat, and the U-shaped stopper is connected to the positioning screw hole via a positioning bolt.

[0010] In some embodiments, the arch frame is disposed inside the inner rotating ring, one end of the arc-shaped connecting rod is connected to the center ring, and the other end of the arc-shaped connecting rod is connected to the arch frame.

[0011] In some embodiments, the arc-shaped rod includes two arc-shaped connecting rods, and the arc-shaped openings of the arc-shaped connecting rods are symmetrically arranged inwardly.

[0012] In some embodiments, reinforcement rods are provided between the arc-shaped connecting rods.

[0013] The invention provides a wind turbine tower rotating flange fixing plate, which has the advantage that the flanges on both sides of the tower can be fixedly connected through the flange connecting seat on the arch frame, so that the tower can be suspended, which is convenient for painting and other operations on the surface of the tower. At the same time, the outer ring of the outer support ring and the inner rotating ring can realize relative rotation through balls and slide grooves, thereby driving the tower to rotate in situ, which is convenient for construction. When rotation is not required, the positioning bolts can be inserted into the positioning screw holes in the middle of the U-shaped stopper to ensure that the inner rotating ring is completely fixed. The arch frame and the arc rod between the center ring and the outer support ring can improve the support strength, but the structure is relatively simple and reduces the cost.
