Embodiment Construction

[0043] In order to describe the technical content, structural features, achieved objects and effects of the present invention in detail, the following detailed description is given in conjunction with the embodiments and the accompanying drawings.

[0044] see Figure 4 , the present invention provides a segmented manufacturing process of the CSS platform connecting bridge region 200, which comprises the following steps: Assembly in deck parts , Assembled in the inner and outer panels as well as big group three parts. Among them, the assembly of the inner outer panel is the most different step in this manufacturing process, which includes the steps of: setting the inner outer panel to bevel the tire frame → hoisting the inner outer panel → welding → centering the "cross" on the platform As a benchmark, carry out the marking of the outer plate structure → hoist the structure on the outer plate and the vertical and horizontal wall plates → fillet welding between the struct...

Abstract

The invention provides a cross structure area segmentation manufacturing process of a CSS platform and a special-purpose inclined cutting jig frame. An inner side outer plate assembly is additionally arranged, an inner side outer plate inclined cutting jig frame is utilized in the assembly, therefore assembling and welding processes are improved, an assembling procedure and a welding position are optimized, fillet welds between a main structure of a cross structure area and an outer plate are all improved from elevation angle welding into horizontal fillet welding, welding quality and construction efficiency are improved, and special position full penetration welding requirements are met; by widening an operation range, a group technology of segmentation manufacturing processes is boosted, alternate operation choices of various work types are reduced, therefore the construction environment is improved, production efficiency is improved, and the segmentation manufacturing period is shortened.

Description

technical field [0001] The invention relates to a shipbuilding process, in particular to a segmented manufacturing process of a CSS platform connecting bridge area and a special beveled tire frame. Background technique [0002] The CSS platform is a dual-body semi-submersible self-propelled living assistance platform, which can meet the needs of human beings for deep-sea development of various purposes. like figure 1 As shown, the connecting bridge area refers to the area connecting the double submersible body 300 and the upper hull 100 . In the CSS platform, this area has high requirements on the strength of the hull structure, and full UT non-destructive testing is required after the structure and the outer plate are welded, so the manufacturing difficulty is very high. [0003] see figure 2 , The traditional manufacturing process of the connecting bridge area is: take the deck as the datum to set up the horizontal tire frame to reverse the structure, and assemble the ...
