Mounting method of convex deck assembly

Abstract

The invention provides a convex deck assembly mounting method. The method mainly comprises the steps that a supporting base and a guide block are preassembled; arranging a supporting structure; hoisting the left and right broadside sections; hoisting the inclined plate subsections; hoisting the top section; the convex deck is assembled in a segmented mode; according to the invention, the full utilization of site resources and crane resources is realized, the working procedure of the convex deck structure with higher construction difficulty is completed on the platform in advance, the workload of a follow-up dock is reduced, the rapid construction of the liquefied gas carrier is realized, and the shipbuilding efficiency is improved.

Description

Technical field [0001] The present invention relates to a method of mounting of a lifted assembly, belonging to the field of ship manufacturing technology. Background technique [0002] At present, the total section of the total segment of the liquefied air boat tabs is not comprehensive. There are the following shortages: 1. After the flange is split into multiple small segments, the total group needs to take up more venue resources, and the venue is high, according to the company The existing venues, production efficiency cannot be further improved, can not meet the company's batch shipbuilding demand; The Longmen crane is also the main production resources of the shipyard. It is not conducive to the rational use of the company's production resources; . Therefore, the development of this mounting apparatus and method will help the liquidation of the total section of the total section of the LNG band. Inventive content [0003] In view of the disadvantage of the above prior art...

AI Technical Summary

Problems solved by technology

[0002]Currently, the general assembly method for the general section of the convex deck of the liquefied gas ship is not comprehensive enough, and there are the following deficiencies: 1. After the convex deck is split into several small general sections, the general assembly time It needs to occupy a lot of site resources and has high requirements for site turnover. According to the company's existing site, the production efficiency cannot be further improved, and it cannot meet the company's batch shipbuilding needs; 2. After the convex deck is split into multiple small sections, each total Each section needs to be turned over, the construction process is cumbersome, and the gantry crane takes a long time, and the gantry crane is the main production resource of the shipyard, which is not conducive to the rational use of the company's production resources; 3. It is necessary to prepare different tire frames for multiple small sections. The workload of production preparation is large, the consumption of materials and manpower is high, and the construction cost is high
