ABSTRACT:
An apparatus and method for holding and inverting cylinder halves of steam turbines is disclosed. The device includes an adjustable base member having a temporary cylinder half support platform. The support includes a jacking mechanism for raising and lower the cylinder half when placed thereon. A rotatable carriage assembly is supported above the base member and securable to the cylinder half flange, the carriage being rotated by a rotation drive unit which is controlled to rotate the cylinder half at a constant rate. After a cylinder half is placed on a support platform, the jacks are activated to raise the cylinder half flange to the level of the rotatable carriage and the flange secured to the carriage. A support is then lowered and removed, and the cylinder half rotated about either its longitudinal or quadrature axis. The axis of rotation is chosen such that the center of gravity of the cylinder half passes therethrough. When maintenance is completed on the cylinder half, it is then removed from the vice by reversing the above steps. Base member is adjustable to accommodate steam turbine cylinder halves of varying dimensions.
