[0037] The working principle of this utility model:

[0038] (1) Assembly of tooling: According to the on-site butt welding, measure the diameters of the first pipe 10 and the second pipe 11, fit the V-mouth of the support mold with the pipe wall, select a suitable installation clamping working surface of the support mold, and use the hexagon socket fixing bolts to pass through the bolt holes of the support mold and fix them in the threaded holes of the fixed base. Repeat the operation to install the support molds on both sides so that the fixture has universal functions.

[0039] (2) Tooling inspection: Check whether the sliding clearance between the movable arm and the guide rod meets the requirements, whether the jaws can be opened quickly, whether the handle of the adjusting screw can rotate flexibly, whether the matching clearance between the adjusting screw and the guide nut and whether the rotation is flexible, whether the movable ball cup and the bolt ball head can rotate flexibly, and whether the pipe support mold and the fixed base are connected and tightened reliably.

[0040] (3) Tooling debugging: reserve a distance of 3-5mm between the two prefabricated first pipe 10 and second pipe 11 to be connected with it, adjust the opening of the support mold, symmetrically press the support mold to form four symmetrical axial lines and the outer wall of the butt-welded pipe to locate the center axis, lightly tighten the handle at one end to fix the pipe at one end, adjust the gap of the butt-welded pipe mouth at the other end to within the specification requirements, check the pipe mouth weld gap, pipe center, and pipe misalignment. After confirming that they are correct, you can carry out the next step of positioning welding, heating and preheating, etc., to facilitate the execution of weld seam welding.

[0041] The process pipeline quick docking tool provided by the utility model has a simple structure, a scientific and reasonable design, is easy to use, operate and disassemble, and has a low cost. Without welding temporary supports, the pipe ends of the two pipes that need to be docked can be conveniently and quickly accurately assembled and installed, which can effectively improve the efficiency of the process pipeline assembly, installation and positioning, and improve the installation and construction progress of the process pipeline.

[0042] Specific implementation steps:

[0043] For on-site pipeline docking, initially adjust the gap between the two pipe ends that need to be docked to 3-5mm for installation positioning, quickly adjust the tooling, slide the opening size of the movable arm and the fixed jaws on the clamping guide rod, and put them on the outer diameters of the two butt-welded pipe openings, manually adjust the movable handle, and adjust the screw rod and guide nut on the movable arm to make it fit tightly against the outer wall of the butt-welded pipe. The movable ball cup has a self-angle adjustment function, so that the clamping support mold can better fit the outer wall of the butt-welded pipe. Check that the pipe mouth gap is within the specification standard, manually pre-tighten and adjust the butt-welded pipe adjusting screw rod, and tighten the adjusting screw rods on both sides at the same time, check the fit between the V-shaped support mold and the butt-welded pipes on both sides, check the butt-welded pipe mouth center and staggered mouth until the gap between the two butt-welded pipe mouths and the left and right symmetrical pipe mouths are free of deviation. After confirmation, symmetrically spot weld the pipes, and the pipeline weld can be carried out without disassembly.
