The invention discloses a dual-purpose stairs climbing device. The device comprises a vehicle body, and further comprises a carriage body enclosed by wall plates, a support frame and a movable hinge arranged at the bottom side of the carriage body, and a vehicle handle arranged at the end part of the carriage body; a roller shaft of a roller device is arranged at one side, opposite to the carriage body, of the support frame; roller bearings are arranged at the two ends of the roller shaft; rollers of the roller device and the roller bearings are movably connected; the middle end of a ratchet device is movably connected with a top leg of an A-shaped frame; a bottom leg of the A-shaped frame is connected with the movable hinge; and a ratchet shaft is arranged in the ratchet device. The ratchet device is arranged below the vehicle body through the A-shaped frame, and a cam is arranged at the support part of the ratchet device, so that such defects as greater jump, higher noise, instable movement, more complicated structure, complex operation, higher manufacturing cost and weak practicability and promotion in the climbing process are prevented; and the device enhances the bearing, improves the efficiency, and is comfortable, convenient and wide in universality.
