A Dock-Based Half-Ship Closing Method

Abstract

The invention provides a half-ship assembly method based on a dock, and belongs to the technical field of ship construction. The method provided by the invention comprises the steps of mounting a first limiting mechanism at the assembly part of the first half ship structure; mounting a second limiting mechanism at the assembly part of the second half-ship structure; sequentially pulling the firsthalf-ship structure and the second half-ship structure into a dock chamber through a winch; starting guide mechanisms on a first dock wall, a second dock wall and a rear dock wall; pushing the first half-ship structure and the second half-ship structure to an assembly position; fixing the first half-ship structure and the second half-ship structure together through the first limiting mechanism andthe second limiting mechanism; firstly welding an assembly joint above a waterline; then starting an assembly device to separate the assembly part of the first half-ship structure and the second half-ship structure from water in the dock chamber; draining the water at the assembly part; and then carrying out welding, polishing and coating operations on the assembly joint to quickly finish the assembly construction of the whole ship. According to the invention, dock resources can be reasonably utilized, and the half-ship assembly efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of ship building, and relates to a dock-based half-ship folding method. Background technique [0002] In shipbuilding, the shipbuilding cycle is an important reflection of a shipyard's construction capability, and it is also an important indicator for measuring and delivering ships and realizing economic benefits. The most direct way to shorten the ship construction cycle is to shorten the berth or dock cycle. [0003] However, the way of building ships in existing docks is single. Use the gantry crane on the dock to hoist the general section into the dock, then splice the various general sections together, and then install and debug the equipment on the ship, then open it to inject water into the dock, and open the dock door. , Pull the ship out of the dock, close the dock door, drain the water in the dock, and lift the general section of the next ship. The entire construction process takes a long time in ...

[0003] However, the way of building ships in existing docks is single. Use the gantry crane on the dock to hoist the general section into the dock, then splice the various general sections together, and then install and debug the equipment on the ship, then open it to inject water into the dock, and open the dock door. , pull the ship out of the dock, close the dock door, drain the water in the dock, and lift the general section of the next ship. The entire construction process takes a long time in the dock and does not make reasonable use of the dock resources.

[0004] If the whole ship is divided into two and a half ships, the utilization rate of the dock can be effectively improved. At present, the two and a half ships are closed and docked in the dry dock. , the tugboat out of the dock prolongs the life cycle of the dock, making the economic efficiency of the shipyard not improved
