Abstract

The invention discloses a method for manufacturing and installing a segmented web of a wind power blade, and belongs to the field of wind power blade manufacturing. The method comprises the following steps that A, web mold manufacturing positioning data is consistent with main mold positioning is confirmed and segmentation point positioning is correct; B, web plate laying layer manufacturing and segmented position processing are carried out; C, the web is poured and formed; and D, web demolding and appearance treatment are carried out; the method further comprises the steps that a, the web is transferred and installed to an integrated tool; b, the web is installed on a shell main beam along with the integrated tool; c, the joint position of the web is reinforced; and d, after an adhesive is cured, the integrated tool is detached, and web installation is completed. According to the method for manufacturing and installing the segmented web of the wind power blade, the problem that a large integrated pouring blade web is difficult to transfer can be solved; the mounting and positioning accuracy of the web on the main beam is improved, and the maintenance cost caused by positioning deviation can be saved; the segmented webs can be installed on the root portion and the tip portion of the integrated tool after being demolded, the transfer space can be saved, and the webs can be transferred more rapidly.

Description

technical field [0001] The invention relates to the field of manufacturing wind power blades, in particular to a method for manufacturing and installing segmental webs of wind power blades. Background technique [0002] Blade is an industry with high certainty, large market capacity and clear profit model among wind power components. Epoxy resin generally refers to organic polymer compounds containing two or more epoxy groups in the molecule. Except for a few, Their relative molecular mass is not high. The molecular structure of epoxy resin is characterized by active epoxy groups in the molecular chain, and the epoxy groups can be located at the end, middle or ring structure of the molecular chain. Due to the active epoxy groups in the molecular structure, they can undergo cross-linking reactions with various types of curing agents to form insoluble, infusible high polymers with a three-dimensional network structure. [0003] The manufacturing technology of wind power blad...
