Abstract

The invention discloses a method for the general assembly and closing of a lifting frame structure of a self-elevating wind power installation platform. The hoisting and positioning of the side box structure, the hoisting and positioning of the upper guide structure, the welding of the lifting frame structure and the surrounding well, the welding of the lifting frame structure and the upper guide, and the post-welding dimension inspection steps complete the assembly and closing of the lifting frame structure of the self-elevating wind power installation platform; The invention optimizes and controls the precision of the final assembly and closing process of the lifting frame structure, overcomes the welding process that is difficult to control the size of the thick plate welding shrinkage assembly, shortens the closing cycle of the lifting frame structure, and realizes precision closing. To achieve the company's goal of reducing labor costs, tooling costs and management costs, improving economic benefits, and increasing the company's technical background.

Description

technical field [0001] The invention relates to a general assembly closing method, in particular to a general assembly closing method of a self-elevating wind power installation platform lifting frame structure. Background technique [0002] In the domestic construction of the lifting frame structure of the self-elevating wind power installation platform, facing the difficult welding structure of thick plates, high strength, full penetration, and small space, deformation is easy to occur, and the closing needs precise positioning to control the verticality of the lifting frame structure And the relative size, so as not to affect the accuracy of subsequent meshing with the leg rack, or even cause the mechanism to fail to work. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art and now provide a self-elevating wind power [0004] A method for closing the general assembly of the lifting frame structure of t...
