Safe and stable pipeline transportation device

The safe and stable pipeline transportation device comprises a bottom plate, supporting square pipes are placed in the centers of the front side and the rear side of the top surface of the bottom plate, buffer springs are fixedly connected to the bottoms of inner cavities of the supporting square pipes, and lifting square pipes are fixedly connected to the tops of the buffer springs; the top of the lifting square pipe penetrates to the top of the supporting square pipe and is fixedly connected with a lower fixing ring, and the right side of the top surface of the lower fixing ring is fixedly connected with a supporting frame. The pipeline transportation device can transport pipelines with different lengths and different diameters, so that pipeline transportation is safer, and the problems that in the pipeline transportation process, a transportation device cannot be correspondingly adjusted according to the diameters and the lengths of the pipelines, so that the transportation device can only transport the pi
