Abstract

The invention belongs to the technical field of pipeline welding and discloses an external opening aligning machine for pipelines. The external opening aligning machine for the pipelines comprises a fixed clamping assembly, a movable clamping assembly, a guide rod and a horizontally-moving hydraulic cylinder. The guide rod is arranged between the fixed clamping assembly and the movable clamping assembly. The horizontally-moving hydraulic cylinder is connected with the fixed clamping assembly and the movable clamping assembly. The fixed clamping assembly comprises a first upper frame and a first lower swing arm. The first lower swing arm is hinged to the first upper frame through a hinge shaft. The movable clamping assembly comprises a second upper frame and a second lower swing arm. The second lower swing arm is hinged to the second upper frame through a hinge shaft. During opening aligning operation, the main pipeline abuts against the inner side of the first upper frame, and the first lower swing arm tightly presses the main pipeline in the first upper frame; the auxiliary pipeline abuts against the inner side of the second upper frame, and the second lower swing arm tightly presses the main pipeline in the second upper frame; and the horizontally-moving oil cylinder pulls the movable clamping assembly to move towards the fixed clamping assembly. The pipeline opening aligning machine which is high in reliability and adjusting efficiency is provided.

Description

technical field [0001] The invention relates to the technical field of pipeline welding, in particular to a pipeline external matching machine. Background technique [0002] Large-diameter long-distance oil and gas pipelines are an important way 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 large-diameter long-distance oil and gas pipelines mainly includes nozzle correction, assembly and weld gap adjustment. There are mainly two ways to complete it, one is done manually, that is, the pipelayer is used to cooperate with the manual external counterpart, and the hydraulic jack or the adjustment bolt is manually operated to complete the correction, alignment and weld gap adjustment of the nozzle. The other is completed in a semi-automatic way, that is, the pipelayer is used to cooperate with the inner counterpart, and the inner counterpart performs automatic ...
