Method for lifting extra-large type bow portion total segment

Abstract

The invention relates to a method for lifting an extra-large type bow portion total segment. The method comprises the following assembling steps that subsections are reinforced, wherein weak gears of the subsections of a bow portion are reinforced through a steel channel connecting frame structure; a, lifters are arranged on the subsections, wherein the lifters for lifting are designed on the subsections, assembling of the subsections is considered, and the lifters of the subsections are utilized by the bow portion total segment for total segment lifting; b, anchor and mooring machines are mounted, wherein the subsections are assembled to form the bow portion total segment, the anchor and mooring machines are arranged on a deck of the bow portion, and wave walls behind the anchor and mooring machines are not mounted; c, the bow portion total segment is lifted; wherein a lower portion of the bow portion total segment forms an overall frame structure through a strong structure of a steel channel connecting total segment longitudinal wall, after the bow portion total segment is welded, the assembling size is measured, and the bow portion total segment is lifted to a ship body; d, the wave walls are lifted; wherein after the bow portion total segment is welded to the ship body, the wave walls are lifted to the deck of the bow portion total segment to be mounted.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a hoisting method for a super-large bow general section. Background technique [0002] The total weight of the bow section of an ultra-large box container ship is relatively heavy. The traditional construction process is to assemble all the sections before the general assembly, and leave the electromechanical equipment for installation after loading. The electromechanical equipment is not installed in time, resulting in underwater The cross-operation of types of work not only affects the delivery period, but also is extremely detrimental to safe production. Especially for the installation of the windlass winch, the laying and commissioning period of the lines and pipelines is relatively long. If it is installed after loading, it will take a lot of delivery period. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention p...
