Abstract
The device (25, 26) comprises a tubular body (40) mounted axially movable on a flange (5) of a transport structure (4) for an object (6), a spring (36) for return of the tubular body (40) towards an unclamped position, an arrangement for manual displacement (19, 20, 16, 21) of the tubular body (40) between its unclamped position and a clamping position, carried by the flange (5), a rod mounted slidably in the axial direction of the tubular body (40) to a limited extent and carrying a shoe (14, 15), and a second spring for elastic return interposed between an abutment fastened to the tubular body (40) and the end of the sliding rod opposite the shoe (14, 15).
Claims10
In a transport structure having at least one bearing surface supporting an object, and a flanging part located opposite said bearing surface, a device for fastening said object comprising
- (a) a tubular body mounted for axial movement on said flanging part between a clamping position and an unclamped position;
- (b) first means for elastic return of said tubular body towards its unclamped position, said first means being interposed between said tubular body and said flanging part;
- (c) means for manual axial displacement of said tubular body between said unclamped position and said clamping position, said means being carried by said flanging part and comprising means for locking in said clamping position on said flanging part;
- (d) a rod mounted for limited axial sliding movement within said tubular body and having a first end carrying, outside said tubular body, a shoe directed towards said bearing surface of said transport structure;
- and
- (c) a second elastic return means, interposed between an abutment fastened to said tubular body and a second end of said rod opposite said shoe, in order to return said sliding rod and said shoe in a direction of said bearing surface.
Device for locking at least one fuel assembly inside a transport container comprising a cradle having at least one set of two right-angled bearing surfaces for said fuel assembly and a plurality of locking flanges mounted in an articulated manner on said cradle about an axis parallel to a longitudinal axis of said cradle, said locking flanges being equipped with devices for fastening said fuel assembly against said bearing surfaces of said cradle, each of said flanges being in one-piece form and comprising two branches at 90.degree., a free end of one of said branches being articulated on said cradle about an axis parallel to said longitudinal direction of said cradle, wherein each of said fastening devices comprises
- (a) a tubular body mounted for axial movement on said flange between a clamping position and an unclamped position;
- (b) a first means for elastic return of said tubular body towards its unclamped position, interposed between said tubular body and said flanging part;
- (c) means for manual axial displacement of said tubular body between its unclamped position and its clamping position, the displacement means carried by said flange ensuring displacement of tubular bodies of the two fastening devices carried by said flange and comprising means for locking on said flange in said clamping position;
- (d) a rod mounted for limited axial sliding movement within said tubular body and having a first end carrying, outside said tubular body, a shoe directed towards said bearing surface of said transport structure;
- and
- (e) a second elastic return means, interposed between an abutment fastened to said tubular body and a second end of said rod opposite said shoe, in order to return said sliding rod and said shoe in the direction of said bearing surface of said cradle.
