Duplex stainless steel chemical tanker deck cabin hoisting precision control method

Abstract

The invention discloses a duplex stainless steel chemical tanker deck cabin hoisting precision control method which comprises the following steps: measuring the three-dimensional size of a bolt hole in a deck cabin segmented connecting plate by using a total station, and adjusting the mounting position of a deck cabin base according to the three-dimensional size of the bolt hole in the deck cabin segmented connecting plate. The positions of the bolt holes in the deck cabin base connecting plate and the positions of the bolt holes in the deck cabin subsection connecting plate can coincide during installation, and after the position of the deck cabin base is adjusted and the deck cabin base is installed, the deck cabin is installed on the deck cabin base. The deck cabin hoisting control method is easy to operate, the deck cabin is accurately installed in place in the hoisting process, the deck cabin hoisting precision and working efficiency are improved, and the hoisting time is shortened.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for controlling the hoisting accuracy of a deck tank of a duplex stainless steel chemical tanker. Background technique [0002] During the design and construction of cargo ships, in order to increase the product load capacity and the flexibility of cargo shipment, 2 or 4 deck cabins are often set up on the deck to increase the number of liquid cargo tanks. The segmental appearance of the deck cabin is in the shape of an octagonal prism, and a connecting plate is provided at the bow end and the stern end of the two sides, and there are two bolt holes on it. On the deck surface, two deck cabin bases are set corresponding to each deck cabin segment, and a connecting plate with bolt holes is also set on the top of the base. After the deck cabin is hoisted, bolts are inserted into the bolt holes between the upper and lower connecting plates. to fix. [0003] Patent No....

AI Technical Summary

Problems solved by technology

But the ship in the above-mentioned prior art can occur multiple situations such as heel, pitch, and roll when sailing, and the deck cabin on the deck surface is segmented, front, rear, left, and right directions only rely on 16 high-strength bolts in the middle of eight connecting plates Fixing, when the gap between the bolt and the connecting plate is too large, it will cause the segmental fixation of the deck cabin to be unstable when the ship is sailing, and there will be a lot of shaking. At the same time, the bolt will be greatly worn and the service life of the bolt will be reduced.
