PURPOSE:To easily perform decontamination work or the like due to honing when a steam turbine is disassembled for inspection, by longitudinally movably constituting a suitable number of receiving bed blocks, housing a disassembled diaphragm, and spreading a space between each receiving bed block. CONSTITUTION:Each blocks 9-11, housing respectively a diaphragm A-C, is mounted onto a bed plate 12, and the block 10 in an even numbered position can be longitudinally moved. Now when the block 10 is moved, for instance, rearward, a controller 19 both drives an oil hydraulic pump 21 and switches a three way type selector valve 22. Then pressure oil, being allowed to flow in a hose 16, is supplied to an oil hydraulic cylinder 15, and the block 10, in a condition that it houses the diaphragm B, moves rearward by force generated in the oil hydraulic cylinder 15. Consequently, the block 10, narrowing a space 2 while spreading a space 4, enables a worker to enter the spread space 4 and perform decontamination work, staining flaw detection, visual inspection, etc. due to honing. |
