Tilt-roll table for use in cleaning UF₆cylinders

摘要

A tilt roll table for use with uranium hexafluoride cylindrical containers securely holds the container, supported from its domed ends by spindles mounted to brackets as the container is tilted and rolled. The spindles have greater surface area over which to distribute the weight and are shaped to complement the domed container ends. The brackets supporting the spindles, stiffened by vertical and horizontal braces, can be adjusted vertically and moved axially toward and away from the domed ends of the containers by a gear drive to accommodate different sizes of cylindrical containers. In addition, bands encircle the containers to hold them onto the frame during tilting and rolling.

主权项

1. A tilt roll table for use in tilting and rolling a UF6 cylindrical container, said apparatus comprising:
(a) a base; (b) a frame carried by said base and adapted to hold a cylindrical container, said frame having a first end and a spaced-apart, opposing second end, said frame being pivotally secured to said base so that said frame can be pivoted between a first-end-higher position and a second-end-higher position, said frame pivoting about a pivotal axis, said frame carrying plural rollers oriented to rotate about an axis perpendicular to said pivotal axis; (c) a pinion gear operatively connected to said frame for pivoting said frame about said pivotal axis; (d) a drive roller operatively connected to said frame for rotating at least one roller of said plural rollers when said cylindrical container is on said frame, said drive roller rotating said cylindrical container about an axis perpendicular to said pivotal axis; (e) a first bracket carried by said first end of said frame and an opposing second bracket carried by said second end of said frame, wherein said first bracket is movably attached to said frame so that said first bracket is movable toward and away from said second bracket, said first bracket carrying a first spindle and said second bracket carrying a second spindle; (f) a motor; and (g) an output shaft driven by said motor, with said first bracket being carried by said output shaft toward said second bracket; wherein, when said cylindrical container is on said frame with a first end of said cylindrical container oriented towards said first spindle and a second end of said cylindrical container oriented toward said second spindle, said first and second spindles engage said first and second ends, respectively, to support said cylinder when said cylinder is rotated by said drive roller and tilted by said pinion gear.
