SYSTEM AND METHOD FOR ASSEMBLING/DISMANTLING OF ROTOR IN STATOR OF TURBOGENERATORS OF 600-800 MW INDEPENDENT OF E.O.T. CRANES

摘要

The invention relates to a system and method for assembling and dismantling a rotor and stator of large turbogenerators upto 800 MW at test bed independent of E.O.T. cranes. The system comprises of a trailer (51) having an erection base (50) mounted thereon moves trolleys (26,27) carrying a rotor (52) towards or away from the stator and a pulling device consisting of a pulling machine (30), guide pulley (14) and wire ropes pulls the rotor into the stator for assembling and away from stator for dismantling after maintaining the alignment of rotor and stator axes. The erection base having longitudinal and transverse plates (41,47) welded and is provided with stiffeners (45,46) for rigidity. Sliding pedestal (4), skid shoe, press boards (9,30) and a supporting pedestal (59) provides support to the moving rotor (52).
