When the two lifting supports 15 are aligned, the traction ropes 21 on both sides are pressed on the pipeline, the lifting arm is controlled to rise, the pipeline is fitted with the lifting support 15 and then stopped, the traction rope 21 is pulled down to make the traction rope 21 in a tensioned state, and after it is fixed on the lower connecting plate 13, the clamping screw 17 can be installed at a suitable position, and the clamping screws 17 on both sides are rotated to make the pressure block 19 press against the center and upper side of the pipeline to fix the pipeline, and finally the pipeline can be lifted normally. The present invention adopts a lifting method to lift the pipeline, and clamps and positions the pipeline by lateral bolts to avoid the pipeline being too heavy and requiring too high a clamping pre-tightening force to damage the anti-corrosion layer on the outside of the pipeline.
