The invention discloses a large valve shaft assembling and disassembling device which comprises a main lifting beam, a lifting part and a positioning part, and the lifting part comprises an adjusting rigging located on one side and a steel wire rope rigging located on the other opposite side. The bottom end of the adjusting rigging and a buckle at the bottom end of the steel wire rope rigging are connected with any two hoisting holes of the main hoisting beam through shackles respectively, the positioning component comprises a long pin shaft, a fixing nut and a positioning flange assembly, and the end, close to the bottom of the main hoisting beam, of the long pin shaft penetrates through the upper hoisting hole and is fastened through the fixing nut. The far end penetrates through the positioning flange assembly and is fixedly connected with the bearing located in the center of the positioning flange assembly; at least two push-in assemblies and a plurality of fixing bolts are installed on the end face of the outer side of the positioning flange assembly in a bilateral symmetry mode, and drawing-out pieces are detachably installed at the center positions of two wing plates of the positioning flange assembly respectively. On the aspects of mounting and dismounting functions, operation is simpler, more convenient and faster, the functions of lifting, mounting and dismounting of the valve shaft are achieved, and butt joint of the valve shaft is more accurate.
