Hoisting process for general section of warehouse deck of orange juice ship

Abstract

The invention discloses a hoisting process for a general section of a warehouse deck of an orange juice ship, which comprises the following process steps of: dividing the general section of the warehouse deck into six deck sections, and combining the general section to form a large ring seam at a deck surrounding a hatch; measuring each deck section, calculating the weight and gravity center position of each deck section, and designing a hoisting point position according to the gravity center position; fixedly arranging a reinforcing structure at the back of the hoisting point of the deck section, and turning over the deck sections; fixedly arranging a hoisting lug at the hoisting point on the front side of each deck section; hoisting the deck sections by adopting a floating crane to rightabove the installation position on the deck surrounding the hatch, using an auxiliary precise landing limit tooling on the deck surrounding the hatch to hoist the deck sections without margins and landing the deck sections to the installation position on the deck surrounding the hatch; according to the invention, the general section of the warehouse deck is divided into six deck sections for construction, so that the problems of narrow construction space and difficult construction of workers due to the fact that the section of the warehouse deck of the orange juice ship is installed after tank bodies enter the warehouse are solved; and hoisting without margins can be achieved.

Description

technical field [0001] The invention relates to a hoisting process for the general section of the deck of an orange juice ship's cargo warehouse. Background technique [0002] As a kind of tanker, a chemical tanker is a cargo ship used to carry various toxic, flammable, volatile or corrosive liquid substances. The earliest bulk chemical tanker appeared in 1948, when the United States refitted the T-2 ordinary tanker "Marinechemical Transport", which can be called the first generation of chemical tanker. With the development of the chemical industry in the 20th century, especially the rise of the petrochemical industry, the demand for the transportation of chemical raw materials and their products is increasing. In the 1980s, a specially designed and built stainless steel chemical ship appeared. Its main features are: tonnage Larger, more densely divided, 70% of the cargo compartment is made of high-strength duplex stainless steel, equipped with advanced control, heating, ve...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the defects existing in the prior art, and provide a hoisting process for the general section of the cargo tank deck of an orange juice ship, which is convenient for workers to operate, and avoids the narrow construction space due to the installation of the cargo tank deck sections of the orange juice ship after the tank body enters the cabin 1. It is difficult for workers to construct, and the cross construction surface of various specialties is large; it realizes hoisting without margin, and does not need to carry out margin cutting processing after hoisting, avoiding the danger of fire hazard caused by later processing of the insulating material on the inner wall of the liquid cargo tank; using lifting lugs It can not be dismantled in the later stage, avoiding the risk of fire hazard caused by the later dismantling of the insulation material on the inner wall of the tanker tank, and the unremoved lifting lug can also be used as a binding piece for the deck surface concentration box and other objects, killing two birds with one stone, and the design is ingenious
