Problems solved by technology
[0002] At present, in the fields of shipbuilding, petrochemical industry, etc., it is often necessary to connect two pipelines to implement technological processes such as ventilation or feeding. The common method is to directly weld the connecting pipe on the flange of the two pipelines on the ship to connect the two Pipelines, due to the limited operating space of the hull, can only be operated manually in most cases, resulting in very inconvenient construction, time-consuming and laborious, and it is difficult to disassemble the welded flanges on the ship if they are scrapped

Abstract
The invention discloses a three-dimensional digital scanning and butting method for a special-shaped pipeline. The three-dimensional digital scanning and butting method for the special-shaped pipelinecomprises the following steps of connecting flange pates to be connected through a connecting strip so as to form a connecting path; sequentially pasting mark paper on the connecting strip along theconnecting path; using a scanner capable of identifying the mark paper for sequentially scanning from the initial end of the connecting strip to the tail end of the connecting strip so as to form three-dimensional data between the flange pates to be connected; importing the three-dimensional data to a 3D design software of a computer; respectively designing and manufacturing new flange plates anda connecting pipe connected with the flange pates to be connected in a matching way through the 3D design software of the computer; and firstly setting a coordinate of one new flange plate as an original point according to the input three-dimensional data through the 3D design software of the computer, and determining a position of the other new flange plate. The three-dimensional digital scanningand butting method for the special-shaped pipeline has the beneficial effects that the method is time and effort saving, less in space limitation, and convenient to construct, and the flange plates are connected stably without being easily scrapped.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a three-dimensional digital scanning butt joint method for special-shaped pipelines. Background technique [0002] At present, in the fields of shipbuilding, petrochemical industry, etc., it is often necessary to connect two pipelines to implement technological processes such as ventilation or feeding. The common method is to directly weld the connecting pipe on the flange of the two pipelines on the ship to connect the two Due to the limited operating space of the hull, the pipeline can only be operated manually in most cases, which makes the construction very inconvenient, time-consuming and laborious, and it is difficult to disassemble the welded flanges on the ship if they are scrapped. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a three-dimensional digital scanning and docking method for special-shaped pipes...
