Method for positioning bottom section and broadside section on heavy lift vessel

Abstract

The invention relates to a method for positioning a bottom section and a broadside section on a heavy lift vessel, which comprises the following steps of: detecting data of the bottom section and the broadside section of the heavy lift vessel by erecting a total station, comparing the detected data with a theoretical value to obtain a three-dimensional change reference value, and obtaining field positioning data of the bottom section and the broadside section; measuring equipment is fully utilized to be combined with three-dimensional analysis software to achieve detection of positioning data of the bottom and the broadside of the heavy lift vessel, the total station is easy and convenient to operate and high in measuring precision, field point position collection can be conducted on bottom data and broadside segments through the total station, and after the collected data are matched with theoretical data of the bottom and the broadside respectively, the positioning data of the bottom and the broadside can be obtained. Therefore, the change conditions of the bottom data and the broadside data can be directly judged on site. According to the method, the positioning precision is high, the change condition of bottom and broadside data can be directly judged on site, the labor intensity of constructors is reduced, and the safety coefficient of the constructors is increased.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a positioning method for realizing the positioning of heavy-lift ship bottom sections and side sections by using a total station. Background technique [0002] The multi-purpose heavy-lift ship is used to load 20-foot and 40-foot containers and some large-scale equipment. Many container legs need to be arranged on the bottom of the cargo hold and the platform, and the dimensional accuracy of the container legs is extremely strict, and the size of the bottom section of the container legs is related to subsequent samples. The most important thing for the success of the box experiment. At present, during the positioning of the shipbuilding enterprises, the overall data of the segment can be obtained through the measurement of the total station when the sub-group is loaded, which greatly improves the efficiency of the sub-group. [0003] In the construction of heavy-lift ships,...

Problems solved by technology

However, the special ship construction of the heavy-lift ship cannot be applied, and the perfect overall group positioning accuracy cannot be obtained, and the carrying efficiency is low, which cannot meet the needs of modern shipbuilding.
