Problems solved by technology

However, for the special section of a dual-fuel large container ship, due to its large structural height difference and relatively weak structure, it cannot be laid up and transported by the conventional step-by-step anti-state laying and transportation of similar gantry cross-step connection profiles. , otherwise the structure will be deformed

Abstract

The invention discloses a shelving and transporting method for special sections of a dual-fuel large container ship. The shelving and transporting method comprises the following steps that a plurality of flower stands are welded and fixed to a portal frame in the length direction of the portal frame; a plurality of gantries are placed in parallel and connected through section bars, and a plurality of placing piers are placed on one side of one of the gantries side by side; sole timbers are placed on the flower stand and the placing piers respectively; the special segments are hoisted and placed on the portal and the laying piers; and fitting-out pieces are installed on the special sections, and then the gantry and the special sections are transported to a target position together through a flat car. The special sections are placed and transported in cooperation with supporting pieces such as the portal frame, the flower stand, the placing piers and the sole timbers according to the structural form of the special sections, and the problem that structural deformation can happen in the placing and transporting process of the special sections is effectively solved.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a lay-up transportation method for special sections of a dual-fuel large container ship. Background technique [0002] The hull structure of the LNG fuel tank area of ​​a dual-fuel large container ship is special, and the structure of the relevant sections and general sections in this area is quite different from the structure of the previously built ship. For special sections with large height differences and complex structures, it is necessary to reconsider their shelving and transportation schemes. [0003] For conventional step divisions, the method of normal shelving and transportation is generally adopted, the door frame is at the same height, and the linear area of ​​the outer plate is supported by profiles as needed. Even with the method of reverse shelving and transportation, the two masts are at the same height, and the supports are connected at the steps as requ...
