The invention discloses a floor lifting machine. The key point of the technical scheme is as follows: the floor lifting machine comprises a pedestal, upright columns, a lifting plate and a lifting device, wherein the upright columns are vertically fixed at four corners of the pedestal; the lifting plate is slidably connected to the upright columns; the lifting device drives the lifting plate to ascend and descend; a protective device for protecting ascending and descending of the lifting plate is arranged on each upright column; a sliding groove is formed in one side, near the lifting plate, of each upright column; a notch is formed in each upright column; the protective device is arranged on the notch; a sliding assembly sliding in the sliding groove is fixed on the side edge of the lifting plate; the protective device comprises a second air cylinder arranged above the notch as well as a protective block rotatably connected into the notch; one end of the protective block is positionedin the sliding groove and the other end of the protective block is positioned on the outer side of each upright column; the bottom of one end, positioned in the sliding groove, of the protective block is provided with an inclined surface; a connecting block is fixed on each upright column; a cylinder body of the second air cylinder is hinged with the connecting block; and a piston rod of the second air cylinder is hinged with one side, stretching out of the upright column, of the protective block. The floor lifting machine has the effect of enhancing the use safety of the lifting machine.
