Flipper block construction method

Abstract

The invention discloses a flipper block construction method. The flipper block construction method comprises the specific steps that a bottom supporting frame is arranged to support a block, wherein the height of the bottom supporting frame is greater than the maximal length of a flipper extending out of an outer base plate, side-edge supporting frames for preventing dumping are arranged at the side edges of the block, and after the block is assembled, installation of a flipper guide rail and lifting and locking tests of the flipper are conducted immediately. According to the flipper block construction method, compared with the prior art, installation and the relative tests of the flipper can be completed at the stage of block assembling, the manufacturing precision and the testing efficiency are improved, the construction period of a whole ship is shortened, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a method for building a lift fin general section. Background technique [0002] In order to carry out seabed surveying tasks smoothly, currently more advanced scientific research ships will be equipped with an elevating fin with a length, width and height of about 3.1m×1.0m×7.2m that can extend out of the outer bottom plate. During the construction process, after the assembly work of the sections where the lift fins are located and the installation of the lift fin guide rails are completed, the lift fins need to be hoisted in place and protrude out of the outer bottom plate by a maximum of about 3.1m for lifting and locking tests to verify the Whether the working position and working status of the equipment are normal. [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 ab...

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
