るものである。 Lead casks, which are used to transport radioactive waste materials to designated locations, are heavy objects, so if they fall due to some kind of accident during transport, they are easily damaged by the impact of the fall due to their huge weight. If such a damaged portion occurs in the cask, a problem may arise in that the waste materials and the like flow out from the damaged portion and contaminate the area around the outflow portion.

供するものである。 The present invention was made in view of the above-mentioned circumstances, and is a cap-shaped cushioning protector for a cask that can be attached to the top and bottom of the cask to absorb shocks against the cask. Appropriate numbers of annular protrusions and disc protrusions each curved outward into a chevron shape are provided on the circumferential part and the disc part of the outer panel for cask covering, which is filled with material and has a through hole in the center. The present invention provides a cushioning protector for a cask, which is configured such that the impact of a fall of the cask can be absorbed by the cushioning material, the annular protrusion, and the disc protrusion.
以下、本考案のキヤスク用緩衝保護具を図面に
示す一実施例に基づき詳細に説明する。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The cushioning protector for a cask according to the present invention will be described in detail below based on an embodiment shown in the drawings.

させるように構成したものである。 In the figure, reference numeral 1 denotes a cask buffer protector of the present invention, which is formed into a cap shape that can be attached to the top and bottom of a lead cask A, respectively. A stainless steel cask covering outer body made of stainless steel and having an appropriate number of annular protrusions 5 and disc protrusions 7 which are bent outwardly in a chevron shape on the circumferential part 4 and disc part 6, respectively. Board 2 and
It consists of a shock-absorbing cushioning material 9 filled inside the outer plate 2, and is configured so that the shock to the cask is absorbed by the cushioning material 9, the annular protrusion 5, and the disc protrusion 7. It is.
尚、前記キヤスク被覆用外板２はその内部にス

外板２に対する衝撃による割損および亀裂を可及
的軽減させるようにしたものである。 Note that the cask covering outer plate 2 is provided with a reinforcing partition wall 8 made of stainless steel inside thereof.
This is designed to reduce breakage and cracks caused by impact on the outer panel 2 as much as possible.
従つて本考案のキヤスク緩衝用保護具は以上の

クを完壁に保護し得るものである。 Therefore, as shown in the above embodiment, the cask buffer protector of the present invention protects the circumferential portion and the disc portion of the cask covering outer plate, which can be fitted with a cap and is filled with a cushioning material, from impact. Since the structure is constructed so that absorbable protrusions are provided to replace and absorb the impact on the cask, if the cask falls due to some kind of accident, the falling impact can be adequately absorbed. Even if an excessive impact is applied to the outer covering panel, the projections provided on the covering outer panel will not affect the cask and will not cause breakage or cracks in the outer panel. It can absorb the impact properly and completely protect the cask.
