Technical Field
[0001] The utility model belongs to the technical field of pipe flange and pipeline alignment, and particularly relates to an alignment device for pipe flange and pipeline. Background Art
[0002] At present, a pipe flange, that is, a pipeline flange, refers to a flange used for piping in a pipeline device. When connecting a traditional pipe flange to a pipeline, a skilled pipe fitter uses instruments such as a square and a spirit level to measure and determine the concentricity and perpendicularity between the pipeline and the pipe flange. After determining the concentricity and perpendicularity, it is fixed by adding shims, jigs or manual support, and then spot-welded by a welder. Therefore, the existing measurement method has high requirements for pipe fitters, and the fixing method is unstable, which is not only time-consuming and laborious, but also prone to errors, resulting in poor accuracy of concentricity and perpendicularity. Content of the Utility Model

A plurality of flange jaws are slidably arranged at one end of the columnar housing, and a plurality of pipeline jaws are slidably arranged at the other end. A first bevel gear disc and a second bevel gear disc are rotatably arranged inside the columnar housing. A gear rod is arranged between the first bevel gear disc and the second bevel gear disc. One side of the first bevel gear disc meshes with the gear rod, and a first scroll gear disc is arranged on the other side. One side of the second bevel gear disc meshes with the gear rod, and a second scroll gear disc is arranged on the other side. A guide groove is arranged on the columnar housing, and one end of the gear rod extends out of the columnar housing through the guide groove. A first groove is arranged on the flange jaw, and the flange jaw meshes with the first scroll gear disc through the first groove. A second groove is arranged on the pipeline jaw, and the pipeline jaw meshes with the second scroll gear disc through the second groove. A pipeline support rod is connected to the pipeline jaw, and the end of the pipeline support rod far away from the pipeline jaw passes through the second bevel gear disc, the first bevel gear disc and the columnar housing in sequence and is placed outside the columnar housing.
[0005] There are three flange jaws in total, and the three flange jaws are evenly spaced in sequence along the circumferential direction of the columnar housing. There are three pipeline jaws in total, and the three pipeline jaws are evenly spaced in sequence along the circumferential direction of the columnar housing.
[0006] The first bevel gear disc and the second bevel gear disc are coaxially arranged.
