Brick reverse modeling auxiliary refractory material management method

Abstract

The invention relates to a brick reverse modeling auxiliary refractory material management method. Based on the reverse modeling technology, firstly, bricks are sequentially formed into a real-scene model according to the use position; and secondly, the real scene model with dense mesh surfaces is exported to 3ds Max in an obj format, and the model is cut into two-dimensional graphics, that is, the three-view drawing of the model reconstruction; brick family files are created through the three-view drawing and are loaded into the project for combination, to complete the coke oven masonry modelof each part, and matching board construction is performed for coke oven masonry according to the daily plan, personnel positioning, brick positioning, positioning boards, fixed-point masonry methodfor board allocation construction. The method of the invention adopts the reverse modeling technology, can precisely reduce the geometric size of the special-shaped brick of the coke oven, and provides the basis for the modeling of the brick; the real scene model with dense mesh surfaces is quickly cut in 3ds Max, the three-view drawing of the model is extracted, and then the three-view drawing isimported into CAD, and the brick solid model is drawn by software tools, which is conducive to the simplification of the model surface.

Description

technical field [0001] The invention relates to the technical field of kiln construction, in particular to a method for assisting refractory material management by reverse modeling of bricks. Background technique [0002] The masonry structure of the coke oven is complex, and there are various types of bricks. Taking the combustion chamber of the coke oven as an example, there are usually dozens of brick types for a single-layer wall, and the wall width gradually changes from the side of the coke pusher to the side of the coke outlet. Small, the interior of the wall is divided into several fire passages by multiple partition walls, and the width of the partition walls is reduced by a few millimeters for every three partition walls. Due to the small amount of decline, masonry masters often use the wrong type of bricks, resulting in uneven mortar joints and even a lot of rework. In order to solve this technical problem, the application number: 201610351262.1 discloses a coke ...

Problems solved by technology

In this way, the brick model needs to be drawn with reference to the brick three-view provided by the design unit, and for some projects that do not have a brick diagram, the brick model cannot be drawn

In addition, the paper "Coke Oven Construction Refractory Information Management Technology" on non-brick model management technology discloses an intelligent management system for coke oven refractory materials, which mainly reflects the layout and division of refractory material warehouses, technical characteristics, key points The technology is to draw the plane and spatial position map of refractory materials, and simulate the warehouse placement of refractory materials. It belongs to the management method of combining two-dimensional plane management and manual data entry. It is managed according to the time of arrival and brick type classification. In the process of realizing masonry, the type and quantity of bricks are related to the sequence of masonry. From the process point of view, it can only be used in the stage of material storage and storage.

[0003] With the reverse modeling technology (that is, according to the existing solid model, scan its data (usually point cloud), and then regenerate its digital model in the 3D environment ) development, the existing bricks can be modeled by 3D laser scanning technology or oblique photogrammetry technology, but the surface of this model has rich textures and dense grid surfaces, and the integration of such brick models will lead to computer Slow operation, even crash
