Mounting method of integral stern shaft tube on naval architecture and ocean engineering

Abstract

The invention relates to a mounting method of an integral stern shaft tube on naval architecture and ocean engineering. The mounting method is used for special tools, and the special tools comprise a conveying plate and an idler wheel support. The mounting method specifically comprises the following steps: firstly, assembling the integral stern shaft tube with the conveying plate integrally, and connecting a steel wire rope with the conveying plate; secondly, mounting the idler wheel support on a ship structure in the subsection of the stern shaft tube in advance; thirdly, lifting the assembled conveying plate and integral stern shaft tube in a dock, and putting the bow end part of the integral stern shaft tube in the ship structure at the subsection of the stern shaft tube; stretching the steel wire rope to a stern engine room area; fourthly, pulling the steel wire rope until the integral stern shaft tube is in place primarily; fifthly, accurately adjusting the position of the integral stern shaft tube in exact place, and effectively fixing the integral stern shaft tube. According to the mounting method disclosed by the invention, the integral stern shaft tube can be effectively prevented from colliding, so that the mounting workload of stern tube assembly is reduced, and the mounting quality and efficiency of the integral stern shaft tube are improved.

Description

technical field [0001] The invention relates to ships and ocean engineering, in particular to an installation method for an integral stern tube, that is, a stern tube assembly, used in ship design, construction and use. Background technique [0002] In the manufacturing process of ships and marine engineering machinery, the overall stern tube (also called stern tube assembly) is usually a whole structure. Generally, the front and rear stern shaft sealing devices have been installed on the integral stern tube, and the integral stern tube (stern tube assembly) and the stern column and the front stern tube seat are fixed by epoxy casting. In addition, relevant oil inlet pipes, oil return pipes and temperature sensors have been installed in the integral stern tube (stern tube assembly), and the tightness (such as water pressure) test of the integral stern tube (stern tube assembly) has generally been completed. In this way, the hoisting of the integral stern tube to the stern s...

Problems solved by technology

[0003] In the prior art, the installation of the integral stern tube (stern tube assembly) generally adopts the method of cooperating with a crane and a chain hoist. Most of the workload in this installation process is completed by manpower, which has relatively high labor intensity and The shortcoming of longer working hours will affect the progress of the project

In addition, many manual operations are prone to damage the overall stern tube (stern tube assembly), which affects the normal operation of subsequent epoxy pouring and other work
