s1, removing old pipelines which need to be replaced on a pipe rack;
s2, moving the detached old pipeline to a supporting block on one side of the pipe rack, and moving the new pipeline to the ground on the other side of the pipe rack;
s3, connecting an upper sliding seat on an old pipeline side upright post with a pull rope, connecting a lower sliding seat on a new pipeline side upright post with the pull rope, connecting a lifting beam between the two upper sliding seats on the old pipeline side, and connecting a lifting beam between the two lower sliding seats on the new pipeline side;
s4, the supporting blocks for supporting the old pipeline outwards move, the old pipeline is connected with the lifting hook on one lifting beam, and the new pipeline is connected with the lifting hook on the other lifting beam;
s5, the supporting blocks for supporting the old pipeline move inwards to return, so that the old pipeline moves downwards under the action of gravity, the new pipeline is pulled upwards through the pull rope, and the old pipeline descends to the ground and ascends to the detached height position of the old pipeline;
s6, the supporting blocks at the side of the new pipeline outwards move and support the new pipeline, the hooks on the new pipeline and the old pipeline are disassembled, the new pipeline is moved to a position on the pipe rack, which needs to be replaced, and the new pipeline is installed;
when the length of the pipeline to be replaced is larger than the distance between the front upright post and the rear upright post, the old pipeline detached in S2 is obliquely placed, and the outer end of the old pipeline is placed between the front upright post and the rear upright post and is close to the upright post; s4, when the longitudinal moving roller on the supporting block rotates to drive the outer end of the old pipeline to longitudinally and outwards move, and when the inner end of the old pipeline moves to a position between the front post and the rear post, the transverse moving roller on the supporting block rotates to adjust the posture of the old pipeline, so that the old pipeline is completely supported on the supporting block; and S6, supporting one end of the new pipeline on the supporting block, rotating the transverse moving roller on the supporting block, driving one end of the new pipeline into the pipe rack, then rotating the longitudinal moving roller on the supporting block, driving the new pipeline to longitudinally move so that the other end of the new pipeline also moves between the front upright post and the rear upright post, completely supporting the new pipeline on the supporting block, and then rotating the transverse moving roller to drive the new pipeline to move inwards for adjusting the gesture.
