The invention provides a heavy object anti-falling device for a high-altitude hoisting machine. The heavy object anti-falling device for the high-altitude hoisting machine comprises a shell; four first sliding rods which are fixedly mounted on the inner wall of the bottom of the shell; four first sliding blocks which are arranged on the four first sliding rods in a sliding and sleeved mode correspondingly; four first springs which are arranged on the four first sliding rods in a sliding and sleeved mode correspondingly, the bottom ends of the first springs make contact with the inner wall of the bottom of the shell, and the top ends of the first springs make contact with the bottoms of the first sliding blocks; a supporting frame which is fixedly mounted on the sides, close to each other, of the four first sliding blocks; and two rotating shafts which are rotatably installed on the supporting frame, and the ends, away from each other, of the two rotating shafts extend out of the shell and are in sliding connection with the shell. The heavy object anti-falling device for the high-altitude hoisting machine provided by the invention has the advantages of being convenient to use and capable of limiting an anti-falling rope in a buffering mode.
