A construction method of lifting fin general section

Abstract

A method for constructing a flipper (2) block (1), specifically comprising: configuring a bottom portion support frame (5) having a height that is greater than the maximum length of a flipper (2) protruding from an outer bottom plate so as to support a block (1), and configuring on a side of the block (1) a side support frame (6) which prevents tilting; after the block (1) is assembled, immediately installing a flipper guide rail (3) and testing lifting and locking for the flipper (2). Compared with the existing technology, the method for constructing a flipper (2) block (1) may complete the installation of and related tests for the flipper (2) during the assembling stage of the block (1), thereby improving the manufacturing precision and test efficiency, and shortening the construction period for the entire ship, while operation is easy.

Description

Technical field [0001] The invention belongs to the technical field of shipbuilding, and particularly relates to a method for constructing a lifting fin total section. Background technique [0002] In order to successfully carry out the seabed survey task, the current more advanced scientific research ship will be equipped with a lifting fin with a length, width and height of about 3.1m×1.0m×7.2m that can extend out of the outer bottom. During the construction process, when the sections where the lifting fins are located are assembled and the guide rails of the lifting fins are installed, the lifting fins need to be hoisted in place and protruded out of the outer bottom plate for a maximum of 3.1m for lifting and locking tests to verify the Whether the working position and working state of the equipment are normal. [0003] Ships are generally arranged on the berth or dock for construction. Whether on the berth or the dock, the height of the dock pier is about 1.6m, that is, the d...

AI Technical Summary

Problems solved by technology

[0003] Ships are generally arranged to be built on the berth or dock. Whether it is on the berth or the dock, the height of the dock pier is about 1.6m, that is, the distance between the outer bottom plate of the ship at the flat bottom position and the dock bottom or the deck surface is only 1.6m, and Neither the bottom of the dock nor the surface of the ship’s platform have pits of corresponding specifications, and the distance of 1.6m cannot meet the requirement that the lifting fins of the scientific research ship can extend up to 3.1m from the outer bottom plate. lock test

In addition, if the lifting and locking test of the elevating fins is carried out after the ship is fully closed and launched, this test can only be carried out in the final sea trial stage (that is, in the open sea stage) due to the limitation of the water depth at the wharf stage

If the lifting fins are tested after being launched, and if there is a problem that needs to be adjusted, because the entire lifting fin casing is open to the sea, the boat must be dragged into the dock before it can be solved. However, due to the limitation of the height of the dock, it cannot be solved at one time. Complete inspection and correction, may require multiple docking and undocking to complete correction
