The adjustable pipeline positioning device first conveniently puts the two pipelines to be welded into the two positioning rings, and ensures the stability of the pipeline fixation through the internal clamping assembly. At this time, the two electric push rods are started to push the two positioning rings to move in relative directions to align the two pipelines, and then according to the needs of the user, the dual-axis motor is started, and the rotating two threaded rods will drive the two sliders to move in relative or opposite directions. At this time, the pull rod will move synchronously with the slider, so as to adjust the pipeline to a suitable height, which is convenient for the operator to weld. Finally, when the angle needs to be adjusted, the motor is started to drive the limit seat to rotate as a whole.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4The utility model provides an adjustable pipeline positioning device, including a base plate 1 and two groups of pipeline bodies 2 to be welded, a plurality of groups of auxiliary support components for auxiliary support of the pipeline bodies 2 are installed on the top of the base plate 1, the top of the auxiliary support component is rollingly connected to the bottom of the pipeline body 2, and the auxiliary support component includes a plurality of groups of support plates 15 symmetrically installed on the top of the base plate 1, a rotating rod 16 is rotatably installed between the two symmetrically arranged groups of support plates 15, and two groups of symmetrically arranged rolling seats 17 are fixedly installed on the surface of the rotating rod 16, and the cross section of the rolling seat 17 is a trapezoidal setting.

[0024] By setting up the auxiliary support assembly, when two groups of pipe bodies 2 are welded, they can be placed on the rolling seat 17. When the pipe body 2 is moved, its bottom will drive the rolling seat 17 to roll, thereby achieving the purpose of facilitating the movement of the pipe body 2. At the same time, it can also provide stable support for the pipe body 2.

[0025] Preferably, a tensioning docking assembly is provided between the two groups of pipe bodies 2, and one end of the two groups of pipe bodies 2 to be welded is tightened together by the tensioning docking assembly. The tensioning docking assembly includes a first connecting shell 3 and a second connecting shell 4 respectively arranged on the upper and lower sides of the two groups of pipe bodies 2, and the first connecting shell 3 and the second connecting shell 4 are locked and fixed together by a positioning assembly.

[0026] During docking, the user can twist the two sets of handles 6 in the same direction. The rotation of the handles 6 will drive the driving screw 5 to rotate, and then drive the two sets of first connecting shells 3 to move through the two sets of threaded sleeves 7. The movement of the first connecting shells 3 will drive the pipe body 2 to move, and then tighten the docking ends of the two sets of pipe bodies 2 to prevent the pipe body 2 from moving during welding.
