Embodiment Construction

[0042] The implementation of the present invention will be illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0043] As shown in the figure, a manufacturing process of a fragmented tower, the specific steps are as follows:

[0044] A. Cut the flanges in pieces and splice them together: such as figure 1 , figure 2 As shown, the integral flange ring segment is cut into pieces with equal circumference by a mechanical cutting machine to form multiple segmented flange segments 1. Compared with flame cutting, the internal radial structure of the flange is not changed, and the fatigue of the flange structure is prolonged. Longevity, ensure that the slotting gap is 3mm-4mm, through multiple special flange splicing tooling 2 splicing multiple fragmented flange segments 1 to form an integral flange structure 3, prepare two sets of ...

Abstract

The invention discloses a manufacturing process of a segmented tower, and the specific steps are as follows: A, segmented flanges are cut and spliced; B, paired tower sections are combined to form a unit tower; C, paired flanges and unit towers are combined; D. Assemble the longitudinal flange strip; E. Install the false flange device; F. Cut the whole into pieces and decompose and place them. The invention has the advantages of: solving the technical problem of finding deformation due to a large amount of internal stress released during the slicing process of the tower, avoiding the cumulative error in the production process, and making the slicing tower always maintain the overall consistency and guarantee its structural rigidity.

Description

technical field [0001] The invention belongs to the field of wind power, and in particular relates to a manufacturing process of a segmented tower. Background technique [0002] In the field of wind power generation, the tower is a large-scale structure formed by connecting multiple unit towers through flanges, which can be used to support the upper impeller and generator set. As the power of the wind turbine increases, the diameter of the impeller becomes larger and larger, the height of the corresponding tower becomes higher and the cross-sectional size becomes larger and larger. Large-diameter towers are usually segmented to meet shipping requirements. [0003] Patent No. 201811540860.9 Connector, slicing tower, manufacturing method, tower and wind turbine, cutting the accommodating groove on the cylinder, installing the connecting component, cutting the cylinder along the axis of the accommodating groove to form the slicing tower, the invention The application has the ...
