Steam turbine rotor blade assembly stop tool

The utility model discloses a steam turbine rotor blade assembly stop tool which comprises a bottom plate, lifting seats are fixedly arranged at the positions, close to the left end and the right end, of the upper surface of the bottom plate, supporting seats for supporting a steam turbine rotor are fixedly arranged at the upper ends of the lifting seats, and the supporting seats can drive the steam turbine rotor to rotate. The upper sides of the supporting seats are further provided with stopping mechanisms for braking and stopping the steam turbine rotor, when the blades of the steam turbine rotor are assembled, the steam turbine rotor is supported through the supporting seats on the two sides, meanwhile, stopping is conducted through the stopping mechanisms, and when the mounting and assembling positions of the blades are adjusted, stopping is conducted through the stopping mechanisms. The steam turbine rotor is driven to rotate through the supporting seat, so that rotation adjustment during assembly is mo
