Embodiment approach

[0049] The end of the first positioning part 20 is fixed with a first positioning ring 21, and the first positioning ring 21 is sheathed on the first adjusting part 30, and covers the connection between the first pipe 10 and the first The other end opposite to the butt end of the pipeline 10;

[0050] Specifically, in the present invention, the first adjusting member 30 is rotatably threaded and fixed on the first positioning portion 20, and a certain gap is left between the first adjusting member 30 and the first positioning portion 20, so as to prevent the increase of sticking. Friction affects the rotation of the first regulating member 30 .

[0051] The end of the second positioning part 50 is fixed with a second positioning ring 51, and the second positioning ring 51 is sleeved on the second adjusting member 60 and covers the second pipeline 40 and the second positioning ring 51. The other end of the pipe 40 is opposite to the butt end.

[0052] Specifically, in the pre...

Abstract

The invention relates to a positioning device for pipeline welding and a construction method of the positioning device. The positioning device is used for positioning butted connection of a first pipeline and a second pipeline and comprises a first regulating piece arranged in the first pipeline in a penetrating mode and a second regulating piece arranged in the second pipeline in a penetrating mode, wherein one end of the first regulating piece penetrates out from the first pipeline to form a first connecting end, a first positioning part allowing to be partially inserted into the first pipeline is arranged at the position, close to the other end, of the first regulating piece, the first pipeline is limited by the first positioning part, and thus the axis of the first pipeline coincides with the axis of the first regulating piece; and one end of the second regulating piece penetrates out from the second pipeline to form a second connecting end, a second positioning part allowing to bepartially inserted into the second pipeline is arranged at the position, close to the other end, of the second regulating piece, thus the axis of the second pipeline coincides with the axis of the second regulating piece, and the second connecting end and the first connecting end are coaxially connected in a position-adjustable mode, so that the corresponding ends of the first pipeline and the second pipeline are in butted connection.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a positioning device for pipeline welding and a construction method thereof. Background technique [0002] In the field of building construction, it is often necessary to carry out the construction of butt welding of large-scale hot-melt pipes. The size of the hot-melt pipe is large. At this stage, the butt ends of the two pipes are generally aligned manually. It is difficult to carry out precise butt joints, and it is impossible to ensure that the pipes are always in a stable state during the welding process, so that the construction quality of the pipe butt welding cannot be guaranteed. It is easy to cause pipeline leakage due to uneven fusion of pipeline welding. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, to provide a positioning device for pipe welding and its construction method, to solve the pr...
