Device for cleaning cylindrical objects, such as bolts

A support device for checking and repairing a heavy rotatable object such as a large turbine rotor comprises a pair of self-aligning support structures for rotatably supporting both ends of the shaft of the heavy rotatable object. In each self-aligning support structure, a roller support base rotatably supporting the corresponding end of the shaft of the object with a pair of support rollers is mounted on a base frame by means of a hemispherical support mechanism, and moreover a jig for adjusting the horizontal rotating position of the roller support base around the vertical axis of the hemispherical support mechanism is disposed in the periphery of the base frame, so that the occurrence of the thrust force on the heavy rotatable object as well as the support rollers is completely eliminated.

Support device for checking and repairing a heavy rotatable object

A support structure utilized for checking and repairing rotatable objects of various kinds, such as a turbine for power generator or a blower fan, includes a roll support base which rotatably supports one end of the rotatable object thereon by means of a pair of rolls which are supported on an adjustable surface plate of a base frame by means of a spherical support mechanism. Due to the spherical support mechanism, the rolls on the support bases can uniformly support both ends of the rotatable object without imparting any thrust to the rolls even when horizontal levelling is not achieved.
