Zusammenfassung: | The utility model discloses a pipeline repair welding device belongs to the pipe -line equipment field. Pipeline repair welding device includes: U type frame, arc sheetmetal and lead screw. U type frame comprises first frame, second frame and the third frame that connects gradually, is provided with the screw on the first frame. The lead screw passes the screw and cooperates with the screw, and the axis of lead screw is crossing with the arc sheetmetal. The arc sheetmetal sets up on the third frame is close to one side of first frame, and the inboard of arc sheetmetal moves towards first frame. The utility model discloses a U type frame is fixed the arc sheetmetal on damaged pipeline with the lead screw, later welds the arc sheetmetal on damaged pipeline, accomplishes the restoration to damaged pipeline. The problem of need close the oil well and the damaged pipeline that emptys that damaged pipeline is connected when pipeline repair welding device restores damaged pipeline in the correlation technique, repar |
