Pressure pipeline installation butt joint device

The utility model discloses a butt joint device for pressure pipeline installation, which belongs to the technical field of pressure pipeline installation and comprises a workbench, a cross frame fixedly installed above the workbench, a butt joint mechanism arranged below the cross frame and convenient for alignment and butt joint of pressure pipes, and a welding mechanism convenient for welding joints of the pressure pipes. After butt joint of the pressure pipes is completed, the servo motors in the two connecting frames work at the same time to drive the two conveying butt joint grooves to rotate in the same direction, so that the two pressure pipes rotate at the same time, a worker pulls the electric welding machine downwards, then the electric welding machine is held by the hand to weld a joint of the two rotating pressure pipes, and the two pressure pipes are connected and fixed together. And then the electric welding machine is loosened, the balancing weight descends under the action of the gravity, one
