Problems solved by technology

[0005] Although the bird's nest assembly bracket can play the role of hoisting the whole head into place after being welded into a whole, in actual use, its structure is relatively complicated, and the manufacturing cost is high. When the bottom head flaps are assembled, the high-altitude adjustment work The quantity is large, and its assembly bracket will hinder the transportation of the bottom head after assembly, so it needs to be dismantled, which increases the workload

Abstract

The invention discloses an ellipsoidal head flap single plate adjusting piece, an assembling device and a method thereof. The ellipsoidal head flap single plate adjusting piece comprises a central plate arranged at the upper end of the ellipsoidal head flap and a plurality of branches extending to the edge of the ellipsoidal head flap along the central plate, wherein each branch comprises an adjusting body with adjustable length, the curved surface shape of the ellipsoidal head flap is adjusted by utilizing the length change of the adjusting body; according to the invention, the shape and sizeof the ellipsoidal head flap can be quickly adjusted, and the process complexity and investment cost in the assembling process can be reduced.

Description

technical field [0001] The present disclosure relates to an ellipsoid head flap veneer adjustment part, an assembly device and a method thereof. Background technique [0002] This part is only the content understood by the inventors, and does not necessarily constitute prior art. [0003] The containment bottom head of the third-generation passive AP1000 nuclear power plant is a super-large ellipsoidal head, which is composed of multiple layers and multiple petals. The whole head is welded into a whole and then hoisted in place. [0004] In order to control the overall shape deviation after the bottom head is welded and formed, sometimes a bird's nest assembly bracket is used, as shown in the public documents CN202037567U and CN107093472A. This kind of bird's nest assembly bracket realizes the assembly of the bottom head through the sequence from bottom to top. [0005] Although the bird's nest assembly bracket can play the role of hoisting the whole head into place after ...
