Process for manufacturing ship hatch cover of ten-thousand-tonnage container ship

Abstract

A process for manufacturing a ship hatch cover of a ten-thousand-tonnage container ship belongs to the shipbuilding field and comprises the following steps of: manufacturing an assembly jig; calibrating the levelness of the assembly jig before building and dividing the assembly jig rationally according to the product; lofting and blanking, detailing shrinkage allowance to each part of the hatch cover, and elaborately setting the shrinkage allowance; fabricating parts: dividing the hatch cover into three major assembly areas, requiring that all structures of the part areas are connected through flat fillet weld or butt weld; assembling the structure of the hatch cover, and then checking and meeting various accuracy requirements; mounting a container foot; performing tracking, supervision and measurement by using QC from container seat marking, before welding of the container seats and after welding of the container seats, repairing the unaccepted container seat immediately, and finally performing a container hoisting test to perfectly guarantee the accuracy of the container foot. With the abovementioned process research and improvement, the production efficiency can be improved to a large extent; and compared with the traditional building way, about 8% of energy can be saved for each set and the building period can be shorted by about three weeks.

Description

technical field [0001] The invention relates to a manufacturing process of a hatch cover for a 10,000-ton container ship, and belongs to the field of ship building. Background technique [0002] For the manufacture of hatch covers for 10,000-ton container ships, the structure of the product is complex, and the accuracy of the container seat is high; the outer plate is thin, and the deformation is difficult to control; if the traditional manufacturing method is used for production, the product needs to be turned over repeatedly for correction to achieve the design. This not only wastes manpower and material resources, but also has a production cycle of nearly three months, which has a great impact on the completion of the entire ship. It is an urgent problem to be solved at present. Contents of the invention [0003] The object of the invention is to provide a manufacturing process for a hatch cover for a 10,000-ton container ship. [0004] The problem to be solved by the...
