A 3D printing system for complex large-scale structural models

Abstract

The invention relates to a 3D printing system of a complex large-scale structural model. A supporting frame (1) is fixedly connected with the a ground foundation, and moving tracks (3) can move up anddown by supporting column guide rails arranged on the two sides; operating platforms (4) can horizontally move along the moving tracks (3); and structure printing components (6) are fixed on the operating platforms (4) through second sliding rails (52) and can transversely move along the operating platforms (4), and mechanical arm groups (8) are connected with third sliding rails (53) connected below the operating platforms (4) through telescopic rotating columns (81). According to the 3D printing system, an experimental object is excavated through a mechanical arm, a slag discharging channelis used for collecting slag in the excavation process, a printing arm is started after excavation, and lining is printed above the excavation position. According to the 3D printing system, through the simultaneous cooperation of the structural printing components and the mechanical arm groups, the fine processing of the complex large-scale structure model simultaneously existing with high quality, high efficiency and high precision can be realized.

Description

technical field [0001] The invention relates to the field of laboratory complex large-scale structural model tests, in particular to a 3D printing system for complex large-scale structural models. Background technique [0002] Engineering structures include civil engineering structures, hydraulic engineering structures, underground and space structures, etc. Before on-site construction, it is often necessary to carry out corresponding model tests on a laboratory scale to provide the basis for feasibility studies. The processing of traditional structural models mainly relies on manpower, which is not only very time-consuming and costly, but also has large errors in the simulation accuracy of geological structures, which is not conducive to the development of model tests. [0003] The traditional 3D printing technology is based on the computer 3D design model, through the software layered discrete and numerical control molding system, using laser beams, hot-melt nozzles, etc....
