UPLIFTING JIG FOR REVOLVING SHAFT AND UPLIFTING PROCESS FOR REVOLVING SHAFT

摘要

PROBLEM TO BE SOLVED: To prevent the overturn during jack-up with a simpler configuration.SOLUTION: An uplifting jig 1 for a revolution shaft 54 of a rotary machine, which is inserted between the revolution shaft 54 of the rotary machine and a bearing stand 2 that surrounds the outer periphery of at least of the lower part of the revolution shaft 54, the uplifting jig 1 for the revolution shaft 54 comprises: a pedestal 8 supported on an inner peripheral surface 2a of the bearing stand 2; a jack part 9 provided between the pedestal 8 and the outer peripheral surface of the revolution shaft 54 to be flexible in a radial direction; the dimension of the pedestal 8 in a radial direction being smaller than the clearance between the revolution shaft 54 and the bearing stand 2 in a radial direction; a rotor receiver 10 provided between the jack part 9 and the revolution shaft 54 to have a cylindrical surface corresponding to the outer peripheral surface of the revolution shaft 54; and a plurality of bearing members 11 provided in the rotor receiver 10 to direct in a direction different from that of the jack part 9.
