The invention discloses a graphite crucible lifting device. The graphite crucible lifting device comprises a support, a lifting assembly, a grabbing assembly, a buffer assembly, a lifting trolley, walking wheels, a stabilizing plate, a traction rope, a rotating wheel, a mounting plate, a first clamping block, a through groove, a fixing block, a hinge lug, a first mounting groove, a second mounting groove, a first pneumatic telescopic rod, a supporting rod, a third mounting groove, a first sliding groove, a push block, a push rod, a sliding block, grippers, a first mounting cavity, a second mounting cavity, a third mounting cavity and a second sliding groove. Compared with an existing graphite crucible lifting device, the arranged lifting assembly of the graphite crucible lifting device is more stable in the lifting process, and shaking is not prone to being generated; according to the grabbing assembly, the space between the grippers can be adjusted, so that the grabbing assembly can adapt to graphite crucibles of different specifications; and according to the buffer assembly, buffering can be generated when the grippers make contact with the crucibles, collision is avoided, the friction force between the grippers and the crucibles can be increased, and the grippers and the crucibles are firmer.
