The invention relates to a dual-purpose conveying device for flat ground and stairs, which comprises a frame, pull rods, idler wheels, sliding blocks and a brake block; the pull rods are fixed in square through slots in the front end of the frame by bolts; connection rods are connected to the frame and dowels at two sides of the pull rod; crankshafts are connected between the frame and the idler wheels; guide rails are arranged at two sides of the frame; the sliding blocks are connected into square slots in upper and lower sides of the guide rails; springs and stop dogs are embedded in arc slots inside and outside the guide rails; the ends of the springs act on the end surfaces of the arc slots while the other ends are used for cylindrical end surfaces of the stop dogs; the stop dogs and the sliding blocks are matched, and the brake block is hinged to the rear end of the frame by a pin shaft. The conveying device can climb stairs in a slide manner, after stair climbing, the crankshaft is rotated to the downside from the upside of a positioning block to contact the idler wheel with the ground, and realize rolling conveying; the structure is simple, and transportation and device storage are facilitated; the use is convenient, the function is diversified and the application value is higher.
