A high-precision and rapid positioning method for side shell plates

Abstract

The invention discloses a high-precision and rapid positioning method for a side shell plate body, which comprises the following steps: S1, assembling the side shell plate bodies according to the requirements of the drawings; S2, using two adjacent end faces of the side shell plate Make the end reference line as the reference edge, draw the side plate rib line and the side plate longitudinal bone line on the side shell plate based on the end face reference line, install the side plate transverse member and the side plate longitudinal member, and Paste the reflective sheet at the measurement point; S3, take the two adjacent end faces of the deck as the reference side to make the end face reference line; S4, close the side shell plate and the deck and perform preliminary positioning, and use the total station to paste the reflective sheet Carry out three-dimensional data measurement of the position, compare with the design data, when the data error is greater than the design requirements, correct the position of the side shell plate; S5, complete the welding of the side shell plate and the deck. The invention can shorten the positioning time of the side shell, improve the positioning accuracy and improve the construction efficiency of the ship.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a high-precision and rapid positioning method for a side shell plate body. Background technique [0002] Fragmentation of outer panels is a relatively common construction method for semi-stereoscopic segments at present. The outer panel segments generally have large linear shapes, weak structural strength, variability, and difficult control of segment positioning accuracy. Therefore, the positioning accuracy of outer panel segments has always been a problem. An important and difficult project for segment precision control. In the past, when locating the outer plate segment, the total station was mainly used to collect points on the whole segment, and the computer segment analysis software was used to compare and analyze the collected data with the theoretical data, and finally send the analysis results to the site for correction. Positioning data is intuitive an...

Problems solved by technology

In the past, when locating the outer plate segment, the total station was mainly used to collect points on the whole segment, and the computer segment analysis software was used to compare and analyze the collected data with the theoretical data, and finally send the analysis results to the site for correction. Positioning data is intuitive and accurate, but seriously affects on-site production efficiency

In the traditional way of positioning, the data collection can only be carried out after the on-site scaffolding is set up, and once the accuracy problem occurs, the fragment may be shifted as a whole, and then the data collection and analysis need to be carried out again, which takes a long time
