Problems solved by technology

Due to the layered hoisting, the pre-outfitting rate of the superstructure of the ship is very low, and many outfitting work can only be done on the hull instead of pre-installation, which will inevitably affect the project cycle of the dock and wharf. Moreover, outfitting work on the hull is a high-altitude operation, which is very unsafe and prone to accidents

Embodiment Construction

[0019] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 , the overall hoisting process of the ship superstructure includes the following steps:

[0021] 1) Calculate the weight center of gravity of the entire ship superstructure. The ship superstructure mainly includes hull structure, outer outfitting, inner outfitting, pipe outfitting, electrical outfitting and other parts. When calculating, the weight and center of gravity of each part can be calculated separately , and then calculate the center of gravity of the entire ship superstructure.

[0022] 2) According to the hoisting capacity and hoisting height of the hoisting device, determine the hoisting range on the superstructure of the ship, because the hoisting devices that can be installed on each ship are different, and their spans and hooking methods are also different. According to the situation to determine the s...

Abstract

The invention discloses a whole hoisting craft of a ship superstructure. The whole hoisting craft of the ship superstructure confirms a group of optical practical hoisting points through a finite element modeling analysis method according to a hoisting working condition requirement of a crane. Hoisting is conducted on the group of practical hoisting points, and deflection which is produced when the ship superstructure is hoisted is enabled to be minimum, so advanced outfitting can be conducted on the ship superstructure before the whole ship superstructure is hoisted so as to improve advanced outfitting rate of a ship block and shorten engineering period of a dock and a wharf. Meanwhile, the advanced outfitting enables the dock working platform to do aloft work on the ground. Therefore, the whole hoisting craft of the ship superstructure not only improves working environment of workers, but also greatly improves safety.

Description

technical field [0001] The invention relates to the field of ship building, in particular to a hoisting process for a ship superstructure. Background technique [0002] The superstructure of a ship is mainly the living area and operating area of ​​the ship. It is composed of multiple decks. During the ship construction stage, there are a lot of outfitting work to be completed in the superstructure of the ship, such as hull equipment, ship systems, power plants, electrical systems, Weaponry equipment, electronic equipment and other ship equipment, installation and commissioning of piping systems, cable laying and hull coating, etc. The construction of traditional ship superstructure is mainly layered hoisting, that is, the deck is hoisted layer by layer to the hull for assembly. Due to the layered hoisting, the pre-outfitting rate of the superstructure of the ship is very low, and many outfitting work can only be done on the hull instead of pre-installation, which will inevi...
