WIPO Patent Application WO/2011/096621
Kind Code:
A1
Abstract:
The present invention relates to an apparatus and method for handling a drum in conjunction with a transport container during drum loading, which impart the added function of gripping a transport container cover to a gripping unit used when loading drums containing radioactive waste onto the transport container, in order to significantly reduce drum loading time and the danger of heavy drums being dropped during the handling of drums, and to prevent the danger of radiation exposure during the handling of radioactive waste. To realize these objectives, the apparatus of the present invention comprises: a drum supplying unit for conveying a drum holding radioactive waste; a transport container on which drums conveyed by the drum supplying unit are sequentially loaded; a holding unit for holding a cover of the transport container during drum loading; and a crane including a gripping unit for selectively gripping and conveying the drum or transport container cover, and an elevating unit having the gripping unit mounted thereon and moving upward and downward and also being conveyed left and right along a guide rail, wherein the gripping unit comprises: a plurality of gripper fingers provided in a circular arrangement a certain distance apart from one another; a finger hydraulic pressure device for reciprocally moving the gripping fingers radially inward and outward; a pad provided on the inner surfaces of the gripping fingers to grip the outer surface of the drum through the operation of the finger hydraulic pressure device; and a latch formed projecting on an inner surface of the gripper to be latched and coupled to the transport container cover.
