Embodiment

[0037] Example: such as figure 1 As shown, a method for positioning and bonding a megawatt wind turbine blade web, the method includes the following steps:

[0038] (1) Locate the position of the web on the girder of the SS shell and the girder of the PS shell: In order to protect the cleanliness of the bonding area of ​​the web, select the 3.375m cross-section, 8.438m on the girder of the SS shell and the PS shell The m section, 16.875m section, 23.652m section, 32.063m section and 38.813m section are positioning sections, (the sections on the SS shell and PS shell are when making the girder of the SS shell and the girder of the PS shell, Based on the leaf root end faces of the girders of the SS shell and the PS shell, measure and mark the section along the length direction of the girders of the SS shell and the PS shell girder, for example, the 3.375m section is the distance between the leaves on the girder Root end surface 3.375m section), tear off the release cloth at the a...

Abstract

The invention discloses a method for positioning and bonding a megawatt wind power blade web. The method comprises the steps as follows: firstly, positioning the web on a big beam of an SS (suction surface) shell and a big beam of a PS (pressure surface) shell, and setting the position of the web by positioning blocks; secondly, applying a mixed bonding agent into a bonding area, lifting the web onto the SS shell by a crane, slightly placing the web onto the scraped bonding agent, just clamping in a gap between the positioning blocks for the trial closing operation, and extruding the web by the weight of the PS shell to bond the web with the SS shell in a fixing way; thirdly, removing the bonding agent from the web bonding area and the front and rear edges of the PS shell; and finally, closing, curing the bonding agent and integrating the PS shell, the SS shell and the web. Through the arrangement of the positioning blocks, the web can be accurately positioned on the shells, and a bonder thickness control piece is arranged in the bonding area to control the thickness of the bonding agent so as to save the usage amount of the bonding agent in the blade closing process and avoid shortage or excessiveness of the bonding agent in the local area in the closing process.

Description

technical field [0001] The invention relates to the field of wind power blade manufacturing, in particular to a web positioning and bonding method of a megawatt wind power blade, which is mainly used in the manufacture of large wind power blades. Background technique [0002] Wind power blades are the core components of the unit, and the blade technology is one of the core technologies of the wind power generation system. It is mainly composed of suction side (SS) shells, pressure side (PS) shells and webs bonded by adhesives. The relative position of the web in the shell also has an important effect on the blade quality. Its performance also directly affects the service life of the blade. Traditional wind turbine blades are difficult to control the positioning of the web on the shell, and it is easy to cause the web to slip on the blade, and the inaccurate positioning of the web also wastes a lot of adhesive. Therefore it is necessary to improve this. Contents of the in...
