The invention belongs to the technical field of steel ladle capping, and particularly relates to a steel ladle capping lifting system anti-unscrewing mechanism and a transformation method thereof. Comprising a cover body and a fixing rod, one end of the cover body is provided with a support, the support is provided with an oil cylinder through an oil cylinder support, the output end of the oil cylinder is connected with a lifting rod, one end of the fixing rod is in threaded connection with double nuts, and the other end of the fixing rod penetrates through the support and then is movably connected to the cover body. The device further comprises a U-shaped connecting piece and a lifting connecting rod, the U-shaped connecting piece is movably connected to the lifting rod, a connecting rod through hole is formed in the bottom of the U-shaped connecting piece, an internal thread connector is welded to the position, below the connecting rod through hole, of the U-shaped connecting piece, and an external thread connector is arranged at one end of the lifting connecting rod. The anti-unscrewing effect is good, the transformation method is simple, and stable operation in the steel ladle capping and lifting process is guaranteed through the double-limiting mode.
