Pipeline cutting supporting frame

The utility model relates to the technical field of pipeline construction, in particular to a pipeline cutting supporting frame which comprises a bottom frame, a supporting frame body and two supporting wheel frames, the supporting frame body is arranged on the upper side of the bottom frame body, a lifting mechanism is arranged between the supporting frame body and the bottom frame body, and the two supporting wheel frames are respectively connected with the supporting frame body in a sliding mode. The two supporting wheel frames are symmetrically arranged relative to the supporting frame, a distance adjusting mechanism is arranged between the two supporting wheel frames, and supporting wheels are rotationally arranged at the upper ends of the supporting wheel frames. By arranging the distance adjusting mechanism, the distance between the two supporting wheels can be conveniently adjusted, and then pipelines with different pipe diameters can be supported; and by arranging the lifting mechanism, the height of
