The utility model changes the single force point of the traditional correction tool, and can disperse the force around the entire ring. By adjusting the bolts, the size of the gap between the corresponding extrusion plates is adjusted, and the gap between the extrusion plates is reduced. , the extruding plate extrudes the supporting ring to expand outward, so that the inner recess of the tower can be lifted.

Description

A tower section ellipticity correction tool

technical field

The utility model relates to the field of tower section production, in particular to a tower section ellipticity correction tool.

Background technique

The tower tube is composed of multiple tower sections. The tower tube is often used in the field of wind power generation. It mainly plays a supporting role in the wind power generation unit and absorbs the vibration of the unit at the same time. In the production process of the tower tube, it is often necessary to move, temporarily put, store, etc. the tower tube. Due to the large volume and weight of the tower tube, and strict production requirements, defects such as deformation, cracks, and twisting cannot occur.

The tower section is made of rectangular steel plates that are crimped and welded. During the production process of the tower section, its ellipticity needs to be corrected to ensure that the geometric shape of the tower section is consistent with the design, and to prevent bending and other problems in the subsequent use of the tower section. If the ellipticity of the tower section is insufficient, such as concave, it needs to be adjusted with a correction tool. The traditional correction tool has a single force point, and it is easy to damage the tower section twice during the process of adjusting the tower section.

It is the purpose of this utility model to design a tower section ellipticity correction tool aiming at the problems existing in the above-mentioned prior art.

Utility model content

Aiming at the above-mentioned problems in the prior art, the utility model is to provide a tower section ellipticity correction tool, which can effectively solve the above-mentioned problems in the prior art.

The technical scheme of the utility model is:

A tower section ellipticity correction tool, comprising a fixed ring, the fixed ring is provided with a number of threaded holes at equal angles, the left and right sides of the fixed ring are covered with a number of support plates equal to the number of threaded holes, the same surface The support plates can be assembled into a ring, the corresponding support plates are connected to the fixed ring by bolts, and an extruded plate is fixedly connected to the end of the support plate facing the outer wall of the fixed ring. The thickness of the extruded plate gradually decreases from one end connected to the support plate to the other end, and there is a gap between the corresponding extruded plates on the left and right sides; the fixed ring is sleeved with a A ring support ring, the thickness of the inner wall of the support ring gradually increases from the left and right ends to the middle position.

The supporting ring is provided with notches.

Advantage of the utility model:

The utility model changes the single stress point of the traditional straightening tool, and improves the whole straightening tool into a ring shape, which can distribute the force around the whole ring, and adjust the size of the gap between the corresponding extrusion plates by adjusting the bolts. , the gap between the extruded plates is reduced, and the extruded plates extrude the supporting ring to expand outwards, so that the inner recess of the tower can be lifted.

Detailed ways

For the convenience of those skilled in the art to understand, the structure of the present utility model will be further described in detail with the embodiment in conjunction with the accompanying drawings:

Referring to Figures 1-4, a tower section ellipticity correction tool includes a fixed ring 1, the fixed ring 1 is provided with a number of threaded holes 2 at equal angles, and the left and right sides of the fixed ring 1 are covered with the threaded holes. Several support plates 3 with the same number of holes 2, the support plates 3 on the same surface can be assembled into a ring, and the corresponding support plates 3 are connected to the fixed ring 1 by bolts 4, and the support plates 3 face One end of the outer wall of the fixed ring 1 is fixedly connected with an extruded plate 31, the thickness of the extruded plate 31 gradually decreases from one end connected to the support plate 3 to the other end, and the corresponding extruded plates on the left and right sides 31 is provided with a gap; the fixed ring 1 is sleeved with a support ring 5 around the periphery of the extrusion plate 31, and the thickness of the inner wall of the support ring 5 gradually increases from the left and right ends to the middle position.

The supporting ring 5 is provided with notches 6 .

When working, put this tool inside the tower, and turn the tower to adjust the bolt 4 corresponding to the position of the ellipticity. By adjusting the bolt 4, the size of the gap between the corresponding extrusion plates 31 can be adjusted, and the gap between the extrusion plates 31 The slit is reduced, and the extruding plate 31 extrudes the support ring 5 and expands outwards, so that the inner recess of the tower can be lifted.

The above descriptions are only preferred embodiments of the present utility model, and all equal changes and modifications made according to the patent scope of the present utility model shall fall within the scope of the present utility model.
