Abstract

The invention discloses a generator and phase modifier rotor drawing and assembling tool. A lifting device drives a rotor to move up and down till that the rotor is coaxial with a through hole, then the head end of the rotor is placed between an upper shaft seat and a lower shaft seat to be clamped and fixed, and then a steel wire rope is driven by a hoisting mechanism to move upwards so that thelower end of the rotor is driven to move upwards; and then a sliding seat driving mechanism drives a sliding seat to move towards the outer side so that the rotor is moved outwards, and finally, the rotor is moved out of a stator chamber. The tool is suitable for drawing and assembling of rotors of a steam turbine generator and a phase modifier, the existing process method is greatly simplified, the efficiency is improved, and meanwhile potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of steam turbine generator maintenance, in particular to a generator and condenser rotor extraction tool. Background technique [0002] During the on-site maintenance of the generator, the pumping and assembly of the generator rotor is the key process during the maintenance of the generator. The existing method of pumping and assembling the generator rotor is complicated, requires the cooperation of multiple people and is equipped with large-scale lifting equipment and large-scale tooling equipment, which has low efficiency and long construction period. . Among the current technological methods, there is the method of connecting long shafts. This method needs to remove the rotor of the steam turbine first, and the process is complicated. In other methods, rotor hoisting requires the use of heavy-duty lifting equipment (mostly truck cranes or cranes), laying large guide rail tooling on the excitation end sid...
