A large-scale pile-tube hoisting mechanical device is characterized in that the large-scale pile-tube hoisting mechanical device comprises a crossbeam, fixing devices, pulleys, a wire rope, hoisting hangers and a tubular column, wherein two ends of the top of the crossbeam are respectively provided with two fixing devices; the pulleys are uniformly spaced at the bottom of the crossbeam; a wire rope is also included, and one end of the wire rope is fixed to one fixing device and the other end of the wire rope orderly passes through the pulleys until fixed to the other fixing device; and a hoisting hanger is installed on the wire rope between each adjacent two pulleys. The large-scale pile-tube hoisting mechanical device has a reasonable structure, is simple to operate and has light dead-weight. As the wire rope is adopted, stress on each hoisting point is balanced. The device provided by the invention is convenient for hoisting on different usage occasions. The device is low-cost and has high work efficiency.
