Auxiliary positioning device for geothermal pipeline connection

The utility model provides an auxiliary positioning device for geothermal pipeline connection. The auxiliary positioning device for geothermal pipeline connection comprises a fixed ring, a sliding ring, a fixed rod, a jacking piece and a driving assembly. According to the utility model, the fixing ring is fixed on the geothermal pipeline on one side through the fastening assembly, and the sliding ring and the fixing ring are positioned on the same geothermal pipeline. The supporting blocks on the fixing rods are located on the outer side of the geothermal pipeline to be connected. The ends of the jacking pieces abut against the outer sides of the geothermal pipelines to be connected by rotating the jacking pieces, and the two geothermal pipelines can be coaxial by adjusting the positions of the jacking pieces. And then the sliding ring is driven by the driving assembly to move in the direction away from or close to the fixed ring, so that the fixed rod is displaced. The geothermal pipelines to be connected mo
