Landing turning-over method for a transverse bulkhead block of container ship

Abstract

The invention provides a landing turning-over method for a transverse bulkhead block of a container ship. The landing turning-over method comprises the following steps that S1, a lifter and a turning-over tool piece are arranged, specifically, the lifter is arranged and installed at an upper port of the transverse bulkhead block, and the turning-over tool piece is installed at a lower port of the transverse bulkhead block; S2, preparation work before lifting is carried out, specifically, a docking block is arranged, the transverse bulkhead block is placed on the docking block, a turning-over supporting piece is arranged at a lower port of the transverse bulkhead block, and a gantry crane is connected with the lifter at an upper port of the transverse bulkhead block through a steel wire rope; S3, the transverse bulkhead block is lifted, specifically, the gantry crane is moved, the upper end opening of the transverse bulkhead block leaves the supporting face of the docking block, and the transverse bulkhead block rotates with the contact face of the turning-over tool piece and the turning-over supporting piece as the axis; and S4, lifting of the transverse bulkhead block is finished, specifically, when the transverse bulkhead block rotates to be perpendicular to the ground, the gantry crane stops moving. According to the landing turning-over method for the transverse bulkhead block of the container ship, the upper limit of lifting weight is increased, lifting points are optimized, and lifting deformation is reduced.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for turning over a general section of a transverse compartment of a container ship on landing. Background technique [0002] The transverse compartment of a container ship has a sheet structure, and the projected area of ​​the total section of the transverse compartment of a large container ship can reach more than 50m*30m. Take the use of the gantry crane to turn over the transverse compartment as an example. There are three hooks in total on both sides of the upper trolley and the middle hook of the lower trolley. Generally, the middle hook of the lower trolley is used as the main hook, and the hook of the upper trolley is the auxiliary hook. At the top of the compartment, the auxiliary hook is arranged at the bottom of the transverse compartment structure. When the weight of the transverse compartment exceeds the upper limit of the hoisting weight of the lower t...

AI Technical Summary

Problems solved by technology

[0003] With the increase of the volume of the transverse compartment, the total section of the transverse compartment of a large container ship is very wide, and the width of the hatch circumference may reach more than 50m. Therefore, the deformation caused by hoisting is relatively large. The installation of the surrounding accessories has brought uncontrollable factors. At present, the hoisting deformation of the transverse compartment is the biggest resistance to the precision control of the compartment.
