Abstract
1,004,499. Handling device for radio-active articles. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 20, 1964 [Aug. 22, 1963], No. 34118/64. Heading B4Q. A device for tilting elongate radio-active articles, e.g. irradiated fuel elements, from a vertical to a horizontal position to facilitate their transfer between hot cells comprises a support 1 fixed to a shaft 12 journalled by bearings 13 in a casing 16. Rollers 5 are supported at intervals along the support 1, the top 7 of the support carrying a device (not shown) for releasing grippers which convey the fuel element 6 to the support. The fuel element 6 (shown in chain-dotted lines) has upper and lower narrow extensions 9, 21 and is lowered by the grippers so that it enters a guide 10 at the lower end of the support. The fuel element is retained on release of the grippers by the engagement of an abutment on the fuel element formed at the upper end of the narrow extension 21 with the lower ends of a stirrup 18 pivoted at 19 on the guide 10. A lever 26 rigid with the shaft 12 carries a counterweight 29 and a further lever 35 rigid with the shaft may be locked by a pawl 37 pivoted at 41 and operated by a lever 40, this pawl being urged into the locking position by a spring 42. A dashpot cylinder 34 connected at 32 to the lever 26 damps the tilting movement about shaft 12. When the fuel element 6 has been deposited on the support 1 and the pawl 37 is released, the fuel element weight overcomes the counterweight 29 so that the support 1 takes up a horizontal position in which it is locked by a further pawl 39. The fuel element 6 may now be removed by pushing it over the rollers 5 since the stirrup 18 swings out of the way. On release of pawl 37 the counterweight 29 returns the support 1 to the vertical.
