Problems solved by technology

[0004] Due to the high installation accuracy requirements of the bow thruster, it is often necessary to perform repeated positioning many times when using the above-mentioned reverse method to install the bow thruster. The positioning is difficult and takes a long time, and sometimes a lot of time may be wasted. time and manpower, the production efficiency is low, and in severe cases, it may even delay the manufacturing period of the entire hull, causing economic losses to the manufacturer

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings, based on a pre-installation process of a bow thruster of a container ship on a hull segment.

[0019] Such as figure 1 , 2 As shown, the container hull section is divided into a lower subsection 1, a middle subsection 2 and an upper subsection 3 according to different working platforms, wherein the lower subsection 1 is used for installing the bow thruster 5.

[0020] During the pre-installation process of the hull section of the bow thruster of the container ship, the lower subsection 1, the middle subsection 2, and the upper subsection 3 of the hull section are first manufactured inversely based on different platforms. Scattered and attached to the outer plate, the so-called anti-state here is exactly the opposite of the state when the hull is running normally. Wherein the lower subsection 1 can change some parts into bulk parts when carrying out reverse state manu...

Abstract

The invention discloses a process for pre-assembling a bow thrustor on a ship body section, which comprises the following steps: manufacturing the bow thrustor; reversely manufacturing an upper subsection, a middle subsection and a lower subsection; turning over the lower subsection to a normal state, and then assembling the bow thrustor on the lower subsection; reversely folding the upper subsection and the middle subsection; and turning over the obtained folding section to the normal state, and normally folding the folding section and the lower subsection. The pre-assembling process reduces the positioning difficulty of the bow thrustor during assembling, and reduces the time for positioning the bow thrustor so as to shorten the construction period of a ship body.

Description

technical field [0001] The invention relates to a ship building method, in particular to a pre-installation process of a ship bow thruster on a ship hull section. Background technique [0002] With the development of science and technology and the needs of modern waterway transportation, the volume of ships built now is also becoming larger and larger. Since the volume of the ship becomes huge, the hull cannot be built as a whole under such circumstances. It can only be constructed by dividing the hull into several blocks. These blocks are called sections. After segmentation, each section is preassembled, and then the preassembled sections are positioned and closed to build the entire hull. Therefore the quality of each subsection preloading quality is often also directly related to the quality of the hull itself. Due to the limitations of the hull structure, the pre-installation of the existing hull segments is generally performed in an inverted state. The so-called inver...
