Embodiment Construction

[0026] A method for closing a ship by calculating rib positions, half-widths and heights using three-dimensional coordinates, comprising the following steps:

[0027] (1) Coordinate system establishment:

[0028] Establish the coordinate system of the stern axis of the ship according to the dock / sway, such as figure 1 shown.

[0029] A pair of control points are arranged every 30m on both sides of the dock / sway, and a certified total station (angle measurement accuracy ±0.5″, distance measurement accuracy ±0.6mm+1ppm) is used for field observation, and the measurement data is connected to the total station via Bluetooth. It is automatically recorded in the dock / sway stern axis coordinate system establishment software, and the observations are made according to the following technical indicators:

[0030] Ø The total station should have the functions of automatic collimation, automatic observation and automatic recording, and its nominal accuracy should meet: the direction m...

Abstract

The invention relates to the technical field of shipbuilding, in particular to a method for gathering ships by calculating frames, half widths and heights with three-dimensional coordinates, and aims to solve the problems of low accuracy, waste of time and force, and large error accumulation in the conventional measuring method. The method comprises the following specific steps: 1) building a coordinate system; 2) building a station for an instrument freely; 3) gathering segmentally; 4) floating and positioning; 5) measuring the principal dimension of ships. The measuring method has the advantages of high accuracy, saving of time and force, and free from error accumulation; measured data can be used for fully and visually reflecting posture of shipbuilding, so that the principal dimension and linearity of ship bodies can be measured and controlled strictly.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for closing a ship by calculating rib position, half-width and height using three-dimensional coordinates. Background technique [0002] The ship design model is a three-dimensional model. During the manufacturing process, the overall three-dimensional model is divided into several small sections for construction. After the small sections are formed, the small sections are assembled into large sections through the general group, and then the large sections are hoisted to the dock / Slipway for the overall closing of the ship. With the change of the market, ships are getting bigger and bigger, and the requirements for shipbuilding precision are getting higher and higher, and the requirements for the construction cycle of ships are getting shorter and shorter. Therefore, improving the assembly time of ships in docks or berths will bring significant economic benefits. ...
