Abstract

The invention belongs to the technical field of bulk carriers. A method for installing a bulk carrier trough bulkhead unloading plate in a segmented stage: (1) Segmentation stage: a middle group of trough-shaped sections, welding the unloading plate on the trough-shaped section of the middle group; the sloped plate of the unloading board The fillet welds of the channel wall plate with the channel segment, the fillet weld of the vertical plate of the unloading plate and the channel wall plate of the channel segment are all double-sided full penetration; Bottom pier, the top plate of the bottom pier is set horizontally, and permanent process holes are set on the top plate of the bottom pier; a large group of double bottom sections and bottom piers; (2) slipway stage: on the slipway, complete the The overall group positioning and welding of the bottom pier and the channel segment, and the positioning and welding of the vertical plate of the unloading plate and the top plate of the bottom pier; the fillet weld of the bottom pier and the channel segment on the double bottom segment, the vertical plate of the unloading plate Fillet welds of straight plates are fully welded on both sides. The invention is used to solve the technical problem that the single-sided full fusion welding cannot guarantee the welding quality during the construction of the unloading plate of the existing bulk carrier.

Description

technical field [0001] The invention relates to the technical field of bulk carriers, in particular to a method for installing a bulk carrier trough bulkhead unloading plate in stages. Background technique [0002] like Figure 1-5 , 13, the unloading plate 2' of the bulk carrier is installed between the trough wall plate 1 and the bottom pier top plate 44'. [0003] The bottom pier is installed on the double bottom section 3 , and the double bottom section includes an inner bottom plate 31 , an outer bottom plate 32 and a longitudinal partition 33 . The bottom pier includes a first side plate 41', a second side plate 42', a longitudinal partition plate 43', and a top plate 44'. The unloading plate 2' cannot be welded on the sections, and can only be packed in bulk. The unloading plate 2' can only be installed and welded after the welding of the trough bulkhead of the slipway and the top plate of the bottom pier is completed. The reasons are: first, the shipyard considers ...
