Problems solved by technology

In the past, the main shipbuilding enterprises in my country have always used the traditional process for the installation of the box column, that is, after the actual positioning and installation of the hatch cover, the box column is positioned according to the height of the hatch cover, which directly leads to the extension of the installation period of the box column, which greatly It affects the overall cycle of container ship construction and becomes a key factor restricting the delivery cycle

Abstract

The invention discloses a height positioning method of container body stand columns. Through such steps as drawing of a center line, drawing of squaring lines, measurement of the levelness, determination of positioning reference points and calculation of the levelness difference by mapping equipment, the hatch cover positioning reference and the container body stand column positioning reference are unified, so that the installation and positioning of the container body stand columns in a dock can be successfully finished before the installation and positioning of a hatch cover and the problem that the dock building period is influenced because the hatch cover is positioned ahead of the container body stand columns is solved. The method can largely shorten the mounting period of the container body stand columns, shorten the mounting period of the whole hatch cover, container body stand column and lashing bridge system of a container ship, and improve the enterprise production efficiency.

Description

technical field [0001] The invention relates to a method for positioning the height of a box body column in a container ship dock, in particular to a method for efficiently and accurately positioning the height of a box body column of a container ship by using surveying and mapping equipment at the dock stage by using a convenient height positioning method. Background technique [0002] At present, the construction of container ships is developing towards large-scale development, and China is undertaking the construction of ultra-large container ships. However, there is still a big gap between my country's shipyards and the world's advanced shipyards in terms of installation methods for key large-scale outfitting of container ships. In order to win the initiative in the fierce market competition and obtain the space for sustainable development, it is necessary to improve the level of shipbuilding technology, and the traditional shipbuilding technology and concept must be inno...
