Disclosed is a hoisting mechanism for a large heavy-load component in a nuclear fusion environment, the hoisting mechanism comprising a base frame (1), a pair of hoisting arms (5), and a pair of arc arms (2), wherein a top electric motor (7) is positioned in the base frame at the front, and a pair of rotating electric motors (8) are positioned in the base frame at the rear; the pair of hoisting arms are respectively arranged on the left side and the right side of the base frame and opposite each other, a first gear (11-1) is connected to an output shaft of the top electric motor, first racks (5-1) opposite each other are respectively arranged on the front side and the rear side of the first gear and on the upper portions of the hoisting arms, the first gear can mesh with the two opposite first racks at the same time, and second gears (10) are respectively installed at positions, corresponding to the rotating electric motors, on the left side and the right side of the base frame; and the arc arms are respectively assembled on supporting points (3) on side faces of the base frame in a sliding manner by means of arc grooves (2-2), a second rack (2-1) is arranged on an outer arc face of the arc arm, the second gear is in transmission engagement with the second rack on the corresponding side, and an output shaft of the rotating electric motor is in transmission connection with the second gear. The hoisting solution is simple in terms of process and has a good adaptability to a narrow space; and the maintenance cost can be reduced.
