The invention relates to a nodular cast iron jacking pipe inner support hoisting system which comprises a jacking pipe and a nodular cast iron pipe, the outer wall of the nodular cast iron pipe is additionally provided with a flange and a concrete layer, the nodular cast iron pipe is used for pushing construction, and the inner wall of the jacking pipe is coated with cement mortar which passes through a centrifugal force exceeding 25 G and is centrifugally coated; the lifting appliance extends into the jacking pipe from the interior of the jacking pipe, so that the jacking pipe is vertically transported in the axial direction, and the lifting appliance comprises a sucking disc which is a bowl-shaped component with an elastic body sealing edge on the peripheral side; the driving beam is used for controlling the suction cup to do reciprocating motion in the radial direction of the jacking pipe; the suction cup is connected with the driving beam through the connecting arm; the length of the driving beam for controlling the single suction cup is larger than the radius of the jacking pipe, and the suction cups are adsorbed to the inner wall of the jacking pipe through the internal evacuation technology. The device has the beneficial effects that the mold is hoisted in and out through the jacking pipe, pouring of outer wrapped concrete is completed, and the production efficiency is improved.
