Problems solved by technology

[0002] The frame of the 5MW wind power plant has the characteristics of large volume and high requirements for assembly accuracy of profile components. After repeated disassembly and installation of the conventional frame, it is difficult to maintain the assembly accuracy of the product, which makes it difficult to locate the product during assembly on the construction site. It is easy to produce large errors, and often cannot be tightly connected with the front frame after assembly

Abstract

The invention discloses a large wind power generator rear rack which comprises a lower part connecting assembly, an upper part connecting assembly, and two supporting frames, namely, a first supporting frame and a second supporting frame; the first supporting frame is parallel to the second supporting frame; the lower part of the first supporting frame is connected with the lower part of the second supporting frame through the lower part connecting assembly; the upper part of the first supporting frame is connected with the upper part of the second supporting frame through the upper part connecting assembly; each supporting frame comprises a bracket main body and a connecting part; and the bracket main bodies and the connecting parts are provided with supports. The invention also providesa production and assembling method of the large wind power generator rear rack. The contact surfaces of the various assemblies are not machined in a unified manner, and are machined according to the practical requirements after equipment carries out trial assembly at a construction site, so that the assembling accuracy of the large wind power generator rear rack is kept, the accuracy requirementsof the matching surfaces are ensured farthest, and the situation that adjustment cannot be performed due to an excessive clearance during overall assembling is avoided.

Description

technical field [0001] The invention belongs to the field of frame technology, and in particular relates to a rear frame of a large-scale wind power generator and a production and assembly method thereof. Background technique [0002] The frame of the 5MW wind power plant has the characteristics of large volume and high requirements for assembly accuracy of profile components. After repeated disassembly and installation of the conventional frame, it is difficult to maintain the assembly accuracy of the product, which makes it difficult to locate the product during assembly on the construction site. It is easy to produce large errors, and often cannot be tightly connected and matched with the front frame after the assembly is completed. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a large-scale wind power generator rear frame and its production and assembly method, which can still maintain the...
