The invention relates to the technical field of silicon carbide furnace crystal growth. A graphite crucible hoisting mechanism is characterized in that the graphite crucible hoisting mechanism comprises a hoisting disc, four plug pin assemblies distributed at equal intervals and angles in the circumferential direction are installed on the hoisting disc, each plug pin assembly comprises a plug pin base and a sliding plug pin, the plug pin bases are fixed to the upper portion of the hoisting disc, and the sliding plug pins are fixed to the lower portion of the hoisting disc. The sliding plug pin is in sliding connection with the plug pin seat in the radial direction of the lifting disc, and the sliding plug pin is used for being transversely inserted into a round hole in the cylinder wall of a graphite crucible when extending out of the outer edge of the lifting disc in the radial direction; the graphite crucible further comprises at least two limiting lugs arranged in the circumferential direction. The limiting lugs are used for being in lap joint with the top of the cylinder wall of the graphite crucible. The lifting device further comprises a universal rotating lifting ring, and a mounting seat is fixed to the upper side of the lifting disc and used for being detachably connected with the universal rotating lifting ring. According to the graphite crucible hoisting mechanism, hoisting of the graphite crucible is facilitated, the graphite crucible hoisting mechanism is not limited by the space of a graphite heater any more, and the working efficiency is improved.
