[0019] When the two ends of the pipeline (adjacent pipeline) are fixed with the two groups of fixing rings, one end of the pipeline is lifted by rotating the lifting screw rod on one side of the pipeline, and after rotating on the lifting sleeve rod, the pipeline can be supported and adjusted in an inclined state to match the height and angle of another pipeline, so that the whole device can adapt to the complex field environment with height difference.

[0021] Further, a scale indicating rod is arranged on the plane of the rotating hemisphere, and a sliding sleeve is sleeved on the indicating rod; the upper end of the sliding sleeve is fixed to the lower end of the fixing ring, and the indicating rod can slide in the sliding sleeve.

[0091] (2) The rotating hemisphere of the lifting unit is rotated, the rotating hemisphere 2 can rotate in the support seat 11, the rotating hemisphere drives the lifting screw rod to rotate synchronously, the lifting screw rod drives the lifting sleeve rod, the direction adjusting unit and the fixing ring to rise synchronously, so as to adjust the butt joint height of the supported pipeline;

[0092] When there is a land height difference, one of the rotating hemispheres on one side of the pipeline is rotated, so that one end of the pipeline on this side is lifted or lowered, that is, the pipeline is in an inclined state, so as to adapt to the environment with height difference, that is, the angle adjustment of the pipeline is completed;
