The invention discloses a mobile lifting loading and unloading machine. A lifting plate is mounted on a frame through a slide block and a linear guide rail; a guide rod is horizontally arranged on the lifting plate; a fork is of a split structure and is divided into left and right fork bodies; guide holes are formed in fork handles of the left and right fork bodies; the left and right fork bodies are mounted on the guide rod through the guide holes; fixed pulleys are mounted at the top of the frame; movable pulleys are mounted on the lifting plate; the fixed pulleys and the movable pulleys are connected through a traction rope; one end of the traction rope is fixedly connected to the top of the frame, and the other end of the traction rope winds across the movable pulleys and the fixed pulleys in sequence and is wound on a winch of the frame; a rotating shaft is arranged in the center of the lifting plate and is sleeved with a symmetric crank, and the two ends of the rotating shaft are hinged with connecting rods; the connecting rods are divided into the left and right connecting rods; the left and right connecting rods are hinged with the handles of the left and right fork bodies respectively; and a symmetric crank-connecting rod-slide block mechanism is formed by the symmetric crank, the connecting rods and the fork. The mobile lifting loading and unloading machine can reduce the labor intensity of porters, and guarantees the goods loading and unloading efficiency.
