Abstract

PURPOSE: A block mounting estimation management method for a shipbuilding yard is provided to systematically manage a three dimensional precision degree of an internal assembly block and an external mounting block for implementing one time block setting as soon as the block is assembled or mounted. CONSTITUTION: The method comprises several steps. A server for managing a design and measurement data file, supporting a shipbuilding design and estimating a block mounting is constructed, a three dimensional precision degree of an internal assembly block and an external mounting block is measured, a precision degree data file is stored at the server, and the precision degree data is shared via all the steps. A length, a numerical equation, a horizontal precision degree error and others relevant to each block are analyzed by comparing the measurement data file with the drawing data file, and the analysis data is stored at a database. A length error, a re-cut amount and gap data is displayed by performing a simulation based on the three dimensional measurement data of the assembly and the mounting block. A pre-finishing drawing construction is performed by analyzing the measurement data of the blocks, to mount and to be mounted, in order to reduce a dock task, e.g., to re-cut the blocks or to release the blocks. All the data on the block design and the block measurement are collected, analysed and stored at a database.

Description

3d setting simulation method for accuracy of erection block and one time setting for ship building yard}

The present invention relates to a method for predicting mounting of a block for improving the precision and mounting of a mounting block for a shipyard, and more specifically, to systematically manage the three-dimensional precision of a field assembly block and a field mounting block in a shipyard. It is related to a method of improving productivity by mounting a block finishing line finishing method and realizing one time setting.

In the prior art, when the assembly of the hull structure block in the assembly line and the assembly completed and the hull block worked in the field, the measured data was inaccurate and an error occurred in the combination. In addition, by designing the blocks to be assembled continuously without correction of such errors, a considerable amount of post-processing is required to eliminate the problems found during assembly by accumulating the continuous errors.

In other words, the precision management of the conventional hull structure is to check the length, verticality, and horizontality using a tape measure, weight, or level gauge. Due to the accumulation of errors, there is a disadvantage that the productivity is reduced due to re-cutting, release, and gap due to accumulation of errors in the dock, resulting in excessive input.

An object of the present invention for solving the above problems is to develop a device that can measure high-precision three-dimensional stereoscopic precision in order to prevent the errors that may occur in the actual combination between the field block and the field block, Development of predictive management system with block precision simulation by manual hand development Using design data and interface and measurement data Block precision simulation by computer can be applied to the block to which dock work is mounted. In addition, the present invention provides a method for improving precision by forming a database by sharing precision information and analyzing problems of precision in majors of design / industry / foreign field.
