Embodiment Construction

[0020] Further illustrate the present invention below in conjunction with accompanying drawing.

[0021] Such as figure 1 As shown, the general assembly method of the engine room of the present invention, the total section of the engine room includes a diaphragm cabin segment 14, a suspended deck platform segment 13, an intermediate deck platform segment 12 and an upper deck platform segment 11, and the intermediate deck platform In the middle of the segment 12 and the upper deck platform segment 11, an engine hatch 16 is provided, which includes the following assembly steps:

[0022] (1) Reinforcement treatment of each segment: The seam allowance of the original big closing cut is cut off during segmental manufacturing, so that the left and right sides form a segment, and the deck and frame are required to be completely welded. After the manufacture of each segmented tire frame is completed, four 30# channel steels are preset and arranged around. After the planking of each ...

Abstract

The invention belongs to the field of construction of ship sections and particularly discloses a method for assembling and lifting an engine room section. The method comprises the following assemblingsteps: (1) each section strengthening; (2) plane base jig manufacture and lining: a positioning support is arranged on a base jig; (3) subsection assembly: a transverse bulkhead subsection and a suspending deck platform subsection are positioned according to a line and the positioning support on the plane base jig, and other subsections are sequentially lifted, positioned and welded after welding; (4) subsection strengthening after assembly; and (5) finished engine room section measurement. By assembling thirteen subsections into one section, the invention obviously improves the carrying speed, ensures the installation integrity of a subsection structure, can assemble various outfits and accessories in place in advance, prevents the vertical crossing operation among different work types and relieves a state of uneven labor force distribution.

Description

technical field [0001] The invention belongs to the field of ship general section construction, and in particular relates to an assembly method for assembling an engine room section into sections, and a hoisting method for hoisting the assembled engine room overall section. Background technique [0002] The engine room of a 16400t chemical tanker has three decks. Due to the thin structure, the traditional construction process is to divide the three decks into 13 sections from the very beginning of the design before construction to prevent construction, turning over, and hanging. Segments are deformed during transportation. Usually several segments are combined into a large segment in the general assembly stage, and the strength of the segment is improved by pre-installation of the pipes. However, this cannot meet the needs of fast loading at all, and at least 5 to 6 liftings are required during the loading process. Each lifting will affect other surrounding work, especially...
