Wind power blade web plate perpendicularity regulating tooling and regulating method

Abstract

The invention relates to the technical field of wind power blade manufacturing, and provides a wind power blade web plate perpendicularity regulating tooling and regulating method. The provided wind power blade web plate perpendicularity regulating tooling comprises two groups of regulating frames (7), wherein each regulating frame (7) is provided with at least one vertical surface parallel to a web plate (2), at least two regulating elements capable of forwards and backwards moving are arranged on each vertical surface, each regulating element is provided with a regulating screw rod arranged in a way of being vertical to the vertical surface of the corresponding regulating frame, each regulating screw rod can forwards and backwards move in a direction of being vertical to the vertical surface of the corresponding regulating frame, the end parts of the regulating screw rods are provided with regulating baffle plates, and the back ends of the regulating frames (7) are provided with support blocks (9) pasted with a blade SS surface casing (1). The regulating method has the advantages that through regulating the regulating screw rods, the regulating baffle plates arranged at the end parts of the regulating screw rods push the web plate to act for achieving the goal of regulating the angle. The tooling and the method provided by the invention have the advantage that the positioning accuracy of the wind power blade web plate in the horizontal and vertical directions can be ensured.

Description

technical field [0001] The invention belongs to the technical field of wind power blade manufacturing, and in particular relates to a wind power blade web verticality adjustment tool and adjustment method. Background technique [0002] Wind turbine blades are usually composed of two upper and lower cavities of the SS shell and the PS shell, as well as girders and webs. Wherein, both the SS surface shell and the inner bottom surface of the PS surface shell are provided with girders. The girder is along the length direction of the SS surface shell and the PS surface shell. The web is composed of two parts, the front web and the rear web, and is an integral structure. The "I" girder structure is composed of the shell girder, front edge web, trailing edge web, and PS girder arranged on the SS surface, and its cross-sectional view is as follows figure 1 shown. [0003] During the production process of wind power blades, it is necessary to complete the fastening of the SS surf...

AI Technical Summary

Problems solved by technology

Since the bottom surface of the shell on the SS surface is arc-shaped, and the girder on the SS surface is stably matched to the shell on the SS surface, and the shape of the top of the girder along the length direction is irregular, it is difficult to ensure the verticality of the leading edge web and the trailing edge web

The positioning deviation in the vertical direction of the web will cause the mechanical properties of the actual web to deviate from the design, seriously affecting the quality of the product

The design life of the fan operation is 20 years. Once there is a problem with the quality of the product, it will greatly affect the operation safety of the blades and cause huge economic losses.

[0004] In order to realize the precise positioning of the web in the blade structure, the invention patent CN103074001 B discloses a web positioning method using a positioning block; firstly, the position of the web on the girder of the SS shell and the PS shell is determined according to the positioning block , the horizontal position of the web is positioned through the width of the girder; the positioning of the bonding block can only complete the positioning of the web in the horizontal direction of the blade, and cannot guarantee the positioning accuracy of the vertical direction of the web

[0005] The utility model patent CN202826413 U discloses a new type of web. The device completes the positioning of the web through a main body steel frame, an adjustment mechanism, and a positioning pin lock mechanism. Using the principle of helix angle, long bolts are used to drive the diamond mechanism. A supporting mechanism is formed, and structural adjustment is realized through the principle of leverage, and then the precise positioning of the web is completed; however, the weight of the positioning device in the patent is too large, which is inconvenient for on-site operation; on the other hand, the positioning device will affect the lower part of the web during the mold closing process Strengthen the laying of glass fiber cloth

By adjusting the lateral positioning mechanism to ensure that the web is kept vertical to the horizontal plane; by positioning the web through the adjustment structure protruding from the blade flange, only the front and rear edge webs of the web can be assembled separately, which increases the operating time; at the same time, the mechanism Protruding from the flange of the leading edge of the blade, the self-weight will easily cause the deformation of the beam, which will affect the accuracy of positioning
