Method for hoisting ud prefabricated part of trailing edge of wind power blade into main form shell layup

Abstract

The invention discloses a method for hanging a wind power generation blade trailing edge UD prefabricated member into a main mold shell body laying layer. The method comprises the steps: firstly, preparing a placing tool of the trailing edge UD prefabricated member, and allowing the state of the trailing edge UD prefabricated member after placement to be consistent with the state in the main mold shell body laying layer; secondly, finding out an installation position of a positioning block on the trailing edge UD prefabricated member through a check plate, and installing the positioning block; followed by preparing a hanging beam, increasing hanging points through the hanging beam, ensuring the state of the trailing edge UD prefabricated member after hanging is not changed relative to the state on the placing tool through selecting a hanging point position, hanging the trailing edge UD prefabricated member stably into the main mold shell body laying layer, and fixing through a fixing tool; and finally, detecting the state of the trailing edge UD prefabricated member in the main mold shell body laying layer by the check plate, and adjusting the state of the trailing edge UD prefabricated member through an adjusting device on the fixing tool, so as to meet requirements. The method can effectively ensure accuracy and reliability of hanging of the wind power generation blade trailing edge UD prefabricated member into the main mold shell body laying layer.

Description

technical field [0001] The invention relates to the technical field of hoisting a UD prefabricated part at the trailing edge of a wind power generation blade into the laying layer of a main formwork shell, in particular to a method for hoisting a UD prefabricated part at the trailing edge of a wind power generating blade into the laying layer of a main formwork shell. Background technique [0002] It is known in the industry that the trailing edge UD of wind power blades is basically made of fixed-width unidirectional glass fiber cloth, which is laid and poured together with the shell. At present, the newly developed 6MW blade, whose trailing edge UD is a whole, has a complicated shape, and cannot be manufactured by the previous method. It needs to be manufactured in advance by prefabricated parts, and it is hoisted into the main mold layer when the shell is laid.

Problems solved by technology

At present, the newly developed 6MW blade, whose trailing edge UD is a whole, has a complex shape and cannot be manufactured by the previous method. It needs to be manufactured in advance by prefabricated parts, and it is hoisted into the main mold layer when the shell is laid.

When the rear edge UD prefabricated parts are hoisted into the main form shell layer, in order to avoid affecting the laid glass fiber cloth and core material, it needs to be hoisted and placed in place once to avoid repeated placement and placement. The UD prefabricated parts have been adjusted too much, so the requirements for hoisting and the state of the trailing UD prefabricated parts are very high. point), the state of the rear UD prefabricated part is not easy to guarantee during hoisting, and it is prone to torsion, which cannot match the main mold layup; at the same time, limited by the shape of the rear UD prefabricated It is not easy to fix between layers, and the fixing method should also avoid the impact on the subsequent vacuum bagging process, which is very difficult
