Abstract

The invention belongs to the technical field of pipeline welding, and discloses a pipe outer root welding device, comprising: a fixed clamping assembly, a moving clamping assembly, a guide rod, a translational hydraulic cylinder, a welding robot and a robot guide rail; the guide rod is arranged on the fixed clamping assembly Between the component and the movable clamping component; the translational hydraulic cylinder is respectively connected with the fixed clamping component and the movable clamping component; the fixed and movable clamping components respectively include: an upper frame and a lower swing arm; the lower swing arm is hinged to the upper frame through a hinge shaft; The guide rail of the robot is fixed on the fixed clamping assembly, and the welding robot is placed on the guide rail; among them, during the counterpart operation, the pipe is against the inner side of the upper frame, and the lower swing arm presses the pipe into the upper frame; the translation cylinder pulls and moves the clamping The assembly moves towards the stationary clamp assembly. The invention provides a root welding device with simple structure, high welding efficiency and reliable alignment.

Description

Technical field [0001] The invention relates to the technical field of pipe welding, in particular to a pipe outer root welding device. Background technique [0002] Large-diameter long-distance oil and gas pipelines are an important method of oil and gas transportation, and a lot of welding work is required during construction. [0003] At present, the preparatory work before the welding construction of the large-diameter oil and gas long-distance pipeline mainly includes nozzle adjustment, assembly and welding gap adjustment. There are mainly two ways to complete, one is done manually, that is, the use of a pipe hanger and a manual external pairing device, manual operation of hydraulic jacks or shape bolts to complete the adjustment of the nozzle, assembly and gap adjustment of the weld. The other is done in a semi-automatic way, that is, a pipe hanger is used to cooperate with the inner pairing device. The inner pairing device automatically adjusts the nozzles to tighten and ad...
