Abstract
1432532 Handling control rods and fuel elements FRIED KRUPP GmbH 4 April 1974 [5 April 1973] 15029/74 Heading B8H Apparatus, for suspending from an overhead, traversable hoist, for handling fuel elements and control rods in a nuclear reactor or storage facility, comprises a mast 1 connectable to the hoist, a lifting body 7 suspended by cables 4 from the hoist and in turn supporting a gripping body 3, and gripping tool holders 17, 18 movable along rails 13, connected to the lower end of the mast, to be selectively positioned beneath the gripping body such that tools 11, 12, for respectively engaging a control rod head 52 and a fuel element 46, may be coupled to the body. The body comprises a sleeve 28 with radially displaceable balls 33 for engagement with an annular groove 27 in a sleeve 44 of a tool, when the body is lowered into the tool, and a pusher 34 movable by a piston 39 to lock the balls in their tool engaging position. Relative movement between the lifting body 7 and the gripping body 3, after the body 3 has located in the tool and on continued lowering of the body 7, controls a valve 90 which in turn controls the flow of air to and from the cylinder 38 containing the piston 39 and hence movement of the pusher. A further piston 84 and cylinder 83 control movement of a pin 62 in the gripping tool 11, which pin acts on balls 70 in radial holes in the tool to connect the tool with a sleeve 71 forming part of the head of the control rods. In the case of the gripping tool 12, the piston 84 acts on a yoke 78 connected via toggle linkages 76 to two pairs of pivoted hook arms 72 to move same between open and closed positions. In alternative embodiments, Fig. 8 (not shown), the piston and cylinders are replaced by electromagnets, and in Fig. 11 (not shown) the balls 33, 70 are replaced by pawls.
