The graphite crucible lifting device comprises a movable support, a lifting mechanism and limiting clamping grooves, wherein one end of the lifting mechanism is fixedly connected with the center of the movable support, and the limiting clamping grooves are oppositely formed in the bottom of the lifting mechanism. The lifting mechanism comprises a lifting support with the upper end connected with the movable support through a lifting air cylinder, a movable plate arranged at the bottom of the lifting support, a circular containing hole formed in the center of the movable plate, a clamping air cylinder arranged on the movable plate, a cover plate arranged at the output end of the clamping air cylinder and a clamping part hinged to the lower portion of the cover plate. The clamping part comprises a first hinge seat arranged on the cover plate, a first connecting rod hinged to the first hinge seat and a second hinge seat arranged at the other end of the first connecting rod, the second hinge seat is fixedly connected with a third connecting rod, and a guide piece of the third connecting rod is arranged on the movable plate. The structure is simple, safety accidents caused by the fact that the graphite crucible touches other objects or people in the moving process are prevented, and the clamping stability of the clamping part is high.
