Problems solved by technology

[0002] The following problems exist in the assembly process of some large-scale refrigeration rooms: the pipelines in the room are intricate, and the positioning of equipment, valves, and pipe sections is difficult; the area of ​​the refrigeration room is large, there are many systems, and the construction process is difficult; there are inherent errors in the building structure walls and equipment foundations. It will affect the installation accuracy and cause rework; if the off-site processing continues to use traditional manual methods, it will not be possible to achieve accurate blanking, and a large number of manual welding and cutting operations will lead to unstable component quality
[0003] Therefore, it is necessary to provide a digital assembly method and system for a large-scale refrigeration room to improve installation accuracy, avoid manual rework, and effectively shorten the construction period

Embodiment 1

[0047] A BIM-based digital assembly method for a large refrigeration room, see figure 1 , including the following steps:

[0048] S1: Use a 3D laser scanner to scan the building environment of the machine room to be constructed to obtain point cloud data;

[0049] Specifically, the following preparatory work is required before construction: users can establish a prefabricated construction concept according to specific project conditions, form a prefabricated construction team, and formulate a feasible prefabricated construction process. Users can also build off-site and on-site prefabrication processing plants according to the volume of the prefabricated construction of the project, and realize the prefabrication, rust removal, painting, module assembly and other processes of the assembly pipeline to meet the processing needs.

[0050] After the above preparatory work is completed, first use a 3D laser scanner to scan the building environment of the machine room to be constru...

Embodiment 2

[0075] A BIM-based digital assembly system for a large refrigeration room, including:

[0076] 3D laser scanner: used to scan the building environment of the construction machine room to obtain point cloud data;

[0077] Computer: used to generate a three-dimensional model according to the point cloud data; generate an arrangement model according to the three-dimensional model; split the preset BIM model to obtain a construction assembly drawing; obtain the assembly data of each pipe section in the assembly process; The assembly data is compared with the construction assembly drawing and the layout model, and the robot is controlled to complete automatic assembly.

[0078] Preferably, the computer is specifically used for:

[0079] Split the preset BIM model according to the construction site and construction conditions;

[0080] Divide the pipe sections and components in the BIM model into several production unit sections according to the type, and generate the pipe section...

Abstract

According to the BIM-based large refrigeration machine room digital assembly method and system provided by the invention, The method comprises the steps of: using a three-dimensional laser scanner forscanning a building environment of a to-be-constructed machine room to obtain point cloud data; generating a three-dimensional model according to the point cloud data; generating an arrangement modelaccording to the three-dimensional model; splitting a preset BIM model to obtain a construction assembly drawing; acquiring assembly data of each pipe section in the assembly process; and comparing the assembly data with the construction assembly drawing and the arrangement model to complete assembly. According to the method, the BIM technology is adopted for leading deepening design, pipeline optimization, organization and drainage, factory prefabrication and field assembly of the refrigerating machine room. because the precision of the BIM model reaches the millimeter level, the installation precision is improved, rework caused by manpower is avoided, material waste is reduced, and the construction period is effectively shortened.

Description

technical field [0001] The invention belongs to the technical field of digital assembly, and in particular relates to a BIM-based digital assembly method and system for a large refrigeration room. Background technique [0002] The following problems exist in the assembly process of some existing large-scale refrigeration rooms: the pipelines in the room are intricate, and the positioning of equipment, valves, and pipe sections is difficult; the area of ​​the refrigeration room is large, there are many systems, and the construction process is difficult; Affecting the installation accuracy will cause rework; if the off-site processing continues to use the traditional manual method, it will not be possible to achieve accurate blanking, and a large number of manual welding and cutting operations will lead to unstable component quality. [0003] Therefore, it is necessary to provide a digital assembly method and system for a large-scale refrigeration room to improve installation ...
