Driving-free rotor dismounting and mounting method

The invention relates to a driving-free rotor dismounting and mounting method, and belongs to the technical field of phase modifiers and generators. The invention provides a crane-free rotor disassembly and assembly tool and a crane-replaced rotor disassembly and assembly method. The disassembly and assembly tool comprises a stator core protection plate, an arc-shaped sliding plate, a supporting plate, a journal bracket, a trolley body, a rotor body trolley bracket, a wire outlet end trolley bracket and a guide rail. The rotor assembling and disassembling tool can replace a travelling crane to play a role in supporting and moving the rotor in the conventional rotor assembling and disassembling process, and it is guaranteed that the rotor is smoothly assembled and disassembled under the condition that no travelling crane exists in a plant; the rotor is supported by the trolley and rolls on the guide rail, so that the rotor is disassembled and assembled, and the problem of disassembling and assembling the rotor
