<p>PURPOSE:To provide a titled supporting device permitting safe and easy positioning of flanges by supporting the flange on a horizontally located supporting table and driving a holder pivotally fitting the table hydraulically thereby positioning the flange vertically. CONSTITUTION:A table holder 220 and a flange supporting table 210 are set in a horizontal position (solid lines ), and a flange, not shown, is placed on these and is fixed. The table 210 of a disc shape is held pivotally fitted to the holder 220 of a disc shape. The holder 220 is pivotally fitted to the stand arms 2311-2314 secured to a holder base 230 by means of a shaft bar 232, and the piston rod 241 of an oil hydraulic cylinder 240 is connected to the holder 220. Said cylinder is connected to the holder base 230. Hence, when the piston of the cylinder 240 is moved upward, the holder 220 and the table 210 are moved to the vertical position of alternate long and two short dashes lines. The holder base 230 is guided freely movably to the right and left on a base guide 250.</p> |
