The invention discloses a portable steel tube inner wall de-rusting vehicle. Steel wire wheels and polishing wheels are arranged on motor shaft brackets of a de-rusting motor of a vehicle body through a frame, so that the de-rusting motor can rotate to drive the steel wire wheels and the polishing wheels to de-rust and polish the interior of a steel tube; springs in limiting grooves perform tensioning on limiting supporting beams, so that wheels on the limiting supporting beams are attached to the inner wall of the steel tube; meanwhile, the limiting supporting beams are connected to the frame and a sleeve through connecting rods, and the sleeve is adjusted by an adjusting nut, so that the distance between the limiting supporting beams and a central shaft is adjusted, and the vehicle body can adapt to more steel tubes with different inner diameters. Thus, the de-dusting vehicle can effectively remove rust and dust on the inner wall of the steel tube, does not raise the dust, and is good in using effect; the inner wall of the steel tube is cleanly de-rusted, and the treated inner wall of the steel tube is brighter; meanwhile, the dust is prevented from floating in a using process, and the environmental pollution is avoided.
