Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing.

[0026] see first Figure 1 to Figure 5 , the general assembly process of the 400,000-ton ore ship's side section of the present invention, the side section 300 involved is composed of a longitudinal bulkhead segment 100 and an outboard side segment 200; wherein, the longitudinal bulkhead segment 100 has 67 No. 11, No. 69 rib 12, No. 71 rib 13 and bulkhead plate 10;

[0027] The general assembly process of the 400,000-ton ore ship side general section of the present invention is carried out on the general assembly platform and includes the following stages:

[0028]Stage 1: draw the position line of the pier on the general group platform 400, first draw the center line 40 of the general side section and the seam lines 41, 42 of the general side section on the general group platform 400, and then draw the side line The distance between No. 67 rib line 43, No. 69 rib line 44...

Abstract

The invention discloses a general assembly process of a 40,000-ton ore sand ship broadside block. The general assembly process comprises the following steps that in stage 1, a position line of a pieron a general assembly platform is marked out; in stage 2, longitudinal bulkheads are hoisted to the general assembly platform in a segmented mode and placed on piers; in stage 3, longitudinal bulkheadsubsections are adjusted; in stage 4, the heights of the head and the tail of the longitudinal bulkhead subsection are checked; in stage 5, the longitudinal bulkheads are fixed to the general assembly platform in a segmented mode; in stage 6, the outboard side is hoisted to the general assembly platform in a segmented mode and placed on the pier; in stage 7, outboard subsections are adjusted; instage 8, the heights of the heads and tails of the outboard subsections are checked; in stage 9, the outboard subsections and the longitudinal bulkhead subsections are temporarily fixed; and in stage10, splicing seams of the outboard subsections and the longitudinal bulkhead subsections are welded. According to the general assembly process of the 40,000-ton ore sand ship broadside block, the manufacturing period can be greatly shortened, waste of manpower and material resources is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a general assembly process of the general side section of a 400,000-ton ore ship. Background technique [0002] The 400,000-ton ore carrier is by far the largest tonnage carrier in the world, and its construction is quite difficult. How to improve the production environment of the enterprise, improve work efficiency, and shorten the construction period under the implementation of the PSPC specification is a key issue that needs to be considered. The weight of the total side section is 350t, and the normal general group is composed of longitudinal bulkhead segments and outer side segments. According to the structural characteristics of the sections, the longitudinal bulkhead sections are positioning sections, and then the outboard sections are positioned. Since the general side section is connected by longitudinal bulkhead, outer plate and three rib beams, and the lower part is completely open, it is difficult to arrange the ti...
