Background
In the long-distance pipeline construction or maintenance process, carry out the gold mouthful of group of pipeline to be the indispensable link, promptly: two sections of pipe are joined together. Before the closed connection is implemented, the steel pipe is cut according to the actual required short section length. Due to the influence of welding deformation and various factors, the axes of the joints of the two pipelines to be connected are not overlapped, but are dislocated to different degrees along the circumferential direction, so that the cutting machine is required to perform the oblique cutting processing on the steel pipe while cutting off the steel pipe and processing a groove, so as to compensate the dislocated deviation of the joints.
At present, a metal joint pairing method in the prior art is a short joint line drawing and blanking method, the method has no professional construction machinery or automatic technical process, the size needs to be measured manually, the unfolding height value of an intersecting line is calculated according to a mathematical formula, and then line drawing and lofting are carried out. When a worker draws a line, coordinates of an x axis and a y axis are mostly drawn on the wide oil felt paper by using a ruler, the x axis is the expansion length of the outer wall of the pipeline, and the y axis is the expansion height value of the intersecting line. When the method is implemented, workers generally only take eight points, connect the lines after the points are taken, and cut out the sample plate by using scissors. After the template is made, the asphalt felt template is laid on a pipeline to be cut, the template is attached to the outer wall of the pipeline as much as possible, white lines are drawn by the aid of the stone, and then the template is cut intermittently along the lines or points by a hand-held cutting gun.
The manual line drawing and blanking easily causes error accumulation, so that the welding opening group is difficult to weld or has no welding point due to the fact that the welding opening is positioned at an eccentric horizontal angle, an unheveled longitudinal angle or various overlapped angles. The method is very dependent on the technical level and experience of a plumber, and the on-site blanking time is long, so that the speed of rush repair and maintenance is influenced.
