Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Now take the 500-ton section turning of a 300,000-ton oil tanker as an example; a method for overweight section turning of a ship includes the following steps:

[0021] A. Clean up the steel plate floor 1 first, and lift the section 4 by a large gantry crane;

[0022] B. Lay the rubber plate 3 under the section 4, install two turbine propellers 2 on one side of the rubber plate 3, and install two lifting lugs 5 on the other side;

[0023] C. Slowly place the segment 4 on the rubber plate 3, wrap the segment 4 with a rubber cover, and the rubber cover and the rubber plate 3 are bonded together to form a sealing body, which prevents water from corroding the segment 4 and prevents the Secondary processing for scratches in subsection 4;

[0024] D. On the steel plate ground 1, surround the segment 4 with a steel plate to form a tank, and pour water...

Abstract

The invention discloses a turnover method for an overweight block of a ship. The turnover method comprises the following steps: cleaning steel plate ground, and hoisting the block by a large-sized gantry crane; laying a rubber plate below the block, mounting two turbine propellers on one side of the rubber plate, and mounting two lifting lugs on the other side of the rubber plate; slowly placing the block on the rubber plate, wrapping the block with a rubber cover, and mutually bonding the rubber cover and the rubber plate to form a sealing element; enclosing the block on the steel plate ground by using the steel plate and forming a tank body, pouring water into the tank body to enable the block to float; hooking the lifting lug and upwards pulling by an upward-pulling hoist on the right side, and meanwhile, enabling the turbine propellers to propel rightwards for enabling the whole block to turnover anticlockwise; when the upward-pulling hoist elevates to a 90-degree turnover orientation, starting a horizontal-pulling hoist to leftwards pull for smoothly turning the section; draining off water in the tank body, dismantling the enclosed steel plate, taking off the rubber plate, and enabling the section to be directly closed.

Description

technical field [0001] The invention relates to a method for overweight section turnover of a ship, in particular for turning over sections outside the hull, and belongs to the technical field of ships. Background technique [0002] The construction of large ships is the future trend, especially ships over 200,000 tons, which can greatly reduce the cost of transportation, but the construction of large ships is more difficult. Currently, they are built in sections, but a section of a large ship It may cost hundreds of tons, and it was built on the construction site when it was built. It is a big problem to turn over when it is closed. At present, it is manually turned over by multiple hoists, so the risk factor is high and it is easy to scratch the hull. Repairing is cumbersome and inefficient, and it often takes a day to complete. It is a problem that needs to be solved urgently. Contents of the invention [0003] The purpose of the present invention is to provide a metho...
