  Adaptation piece for clamping normal containers

  The present invention relates to an adapter piece for clamping standardized containers onto

  transfer ports to premises with

  dio-activity, preferably for the supply port

  placed at the bottom of a hot cell or a glove box with a box whose transfer port may be closed towards the radioactive space by means of what is called a double cover half of which closes the orifice of the room and the other half of which

  can be coupled to the first, is likely to be

  to be tilted with it in the casement of the room

  adaptation to release the orifice.

  In particular, the invention relates to a part

  the height of which corresponds approximately to the

  thickness of the protective blanket above the hot cell, and whose boot case is likely to be

  put in place in the hole of the protection.

  With the aid of such an adaptation piece, intervention boots and remotely controlled locks are

  put in place by means of

  standards on the transfer port of the cover plate of a hot cell or box

  The adapter is then used as a connecting piece.

  2 - ment can be carried out in two ways: rigid connection directly to a flexible connection airlock through compensation parts on larger interventional boots. The present invention thus relates to the entry and exit lock of people and very large components in the case of cell installations

  hot or what are called boots or boxes.

  The very large components are, until now, under

  generally wrapped in plastic and locked in

  through the opening in the cover or through the interventional door Intervention personnel enter the hot cell in combination with a frogman either through the intervention gate, or using a ladder or a similar way through the hole in the cover By increasing the air flow in the area of intervention, we sought to maintain the spread

  contamination as low as possible.

  A particular disadvantage is then the difficult packaging

  and requiring a great personal effort of the objects during the exit lock to prevent the spread of

  contamination There is also a relative exposure to

  high level of radiation

  during long periods of preparation.

  The object of the present invention is to create an adaptation boot of the type initially mentioned which can be implemented universally, and

  means of which a system of

  neurode or boot, which can be made up of different modules, each module having various coupling locations by means of which it can be connected directly to the transfer port of the hot cell or to another module. 'lock from

  intervention boots in, for example,

  3.- taminates can be carried out in a simple, fast and space-saving way The necessary movements for the processes of lock or coupling, must

  then be able to be accomplished from the protected side.

  Finally, the free passage through the adaptation box must be altered only as little as possible, to be able to use the maximum cross section of the opening

of the cell.

  To achieve this goal, the invention proposes, in the case of an adapter piece of the type initially described that, the mechanisms for tilting and coupling the one

  to the other the two parts of the double lid, are sus-

  can be manipulated from the outside of the cabinet It

  is also proposed in the case of a form of

  especially preferred in which the height of the adapter piece corresponds approximately to the thickness of the protective cover over the hot cell, while the housing of this adapter piece is placed in the orifice of protection, that the mechanisms placed

  on the outer side of the casing wall, are

  maneuvered from the upper access-

ble of the protective blanket.

  It is further provided, in accordance with the

  that the mechanisms are driven by means of rotating shafts, the ends of which project obliquely or vertically next to the casing of the recess in

  the protective cover, these ends being

  to servo drives.

  It is also planned, in particular

  advantageously, that on the lid of the airlock is

  worn a bootie into which penetrates, from the bottom by

  a hole in the lid, a buffer for centering or

  beneath the oblique entrance surfaces of which horizontally mounted wedge

  and double levers with the training of which the ex-

  tremité is placed by being accessible from the top on the outer side of the boot. Finally, according to the invention, it is provided that on the upper face or at the orifice of the box, there is placed a fixed casing whose free passage can be closed by means of lamellae placed inside and likely to tip # the actuating legs of the lamellae being placed on the outer side of the fixed casing

  Other features of the present invention

  will now be described with reference to the following

  that of Figure 1 with a closing piece superior

re modified.

  As shown in FIGS. 1 and 2, the casing of the adaptation piece or the airlock is

  essentially consisting of a sheet metal box 1, which is

  dapte in the recess 2 of the protective cover 3 5.- of a hot cell or other radio-active room, after removal of the cap of the cover, the height of this case corresponding to approximately the thickness of the protective cover 3 The body 1 rests on its lower surface on the cover 4 of the cell and its space

  internal connection can be connected to the internal space 5 of the

  lule through port 6 of the cover.

  The opening 6 of the cover is in the cover 4 of the cell and constitutes the access to the internal space 5

  of the cell from the top to the port 6 one must

  by means of the box in t 8 the 1, connect other

  boots 7 or similar receptacles represented only

  In principle, the connection can be made either directly

  rigidly to an airlock as shown

  in Figures 1 to 6 or flexibly

  of a compensation part (Figure 7) on a large scale

intervention boots.

  The adaptation piece consists essentially of

-

  box 1 with the closure cover 8 of the lock chamber 9 of the cell,

  of the central coupling 10 with the drive 1 11 (see

gure 2),

  tilt ment 12.

  The cover 8 of the lock and the cover 9 of the

  cell are likely to be connected together to

  storing what is called a double cover, the connection

  being performed by means of the central coupling 10.

  The lid 8 of the airlock is pressed by the

  tilt 12 on the watertight inner edge 13 of

  the box 1 of the lid and it closes the airlock down.

  The tilting drive 12 is self-braking and

  in the embodiment represented essentially by

  by means of a compressed air motor 14, an element

  pin 15 and a lever arm 16 from 6.- from the outside of the lid boot 1, all these elements

  being reported on the outer side of boot 1.

  The tilting drive 12 assumes

  be the function of switching parts 8 and 9 of the cover

  coupled or clamped together, from the hole

  6 in the inner space 17 of box 1, until

  they come and stay in the niche 18 and leave

  the free passage of the boot 7 in the cell 5 according to all

  the cross section of the box 1.

  As can be seen in Figure 3, the

  8 is articulated from the top by means of the holding tabs 19 so as to be able to turn on two levers

  rotary devices 20 which, in turn, are fixed on a working shaft

  slope 21 mounted laterally under the casing 1 On this

  shaft 21, which leaks out of the casing 1, is tight.

  The lever 16 is fixed at the protruding end 22 so that, when the lever 16 is pivoted, the cover 8 is lifted from its seat, but remains mobile.

  relative to this pivoting movement or by

  port to the rotary lever 20 about the axis 23 This mobi-

  It is necessary so that the parts 8 and 9 of the lid coupled together can, after the tilting, come to fit exactly in the niche 18, in which case their position relative to the rotary lever 20, must be

changed.

  To reach this position, the lid 8 of the airlock or the two lid parts 8 and 9, are

  guided during the tilting movement in a cou-

  smooth 24 inside 17 of the cover boot.

  both sides on the inner side of the wall as

  this is visible in Figure 2 For this purpose, are reported

  vertically on the upper face 25 of the cover, two support arms 26 on which are placed rollers 27 which, for their part, slide in the slides 24 against the wall of the box of the lid The slides 24 are 7.- then constituted by vertical guide slots which are inclined in their upper part 29 from

the vertical of the niche 18.

  the unwinding of the movement during the tilting of the parts of the cover 8 and 9 fulfills in the version shown two conditions:

  approximately vertical displacement of the cover at

  firing of its seat in the hole 6, under a component which can be in the box 1, "plunge of erasure" lateral occupying the least of

possible place.

  This desired course of movement is obtained

  naked by combination of the displacement in a circular arc of the rotary lever 20 and the rectilinear guidance of the arms of

  support 26 in the groove or slide 24 specially

swam for this purpose.

  As already mentioned, the shaft 21 is rotated by means of the lever 16, which in turn is

  articulated on the spindle lifting element 15 which

  vote the lever 16 or pulling it upwards as in

  of this lifting element, an engine is used

  with compressed air 14 because it can be very well

  a telescopic drive shaft 30 with a polygonal profile, the gimbaled end points 31, 32 of which are provided in such a way that the shaft

  can follow the shift movement of the covers

  keys 8 and 9 and when these lids are open,

  still feel a free passage of 1 meter.

  The rotational movement of the drive shaft

  30 is guided through the lower universal joint 31 and oriented in the bevel gear transmission 34 on the upper face of the cover 8, being transmitted to the displacement pin 35 of the central coupling 10 (FIGS. 6) Using this

  pin 35, the two wedge slides 36 acting horizontally

  zontalement in the casing 40, are by means of the levers 37 articulated in their middle, pressed under the

  oblique surface 38 of the centering pad 39 and they

  box 1, also with boot 7 and serves as security

  to secure the fall of the connection between the body 1 and the boot 7 or in combination with the body 1 alone, to pocket the fall to the outside during transport This security is obtained by the radial pivoting of the slats 43 in the The slats 43 are placed on vertical shafts 45 which are sealingly mounted in the fixing box 42, the shafts 45 being rotated by levers 46 placed on the outside and which can be moved to way

of pins 47.

  advantageous embodiment of the adaptation piece according to

  me to the invention Instead of the fixing boot between the

  boot 7 and the sheet metal box 1 of Figure 1, it is

  seen a flexible connection consisting of two plates or annular flanges 50 and 51, which are connected together

  by a pleated bellows 52, so that it

  The guiding or centering of the plates 50 and 51 is carried out by means of the guide pins or the guide bushings 53. or the support of the weight is assumed by an elastic element, not shown in more detail, inside

  folded bellows 52 or on this bellows.

  This flexible coupling has different functions: height compensation (connection of

  the cell and upper surface of the cover) to diffe-

  different thicknesses of cover,

  compensation for differences in parallelism of

  faces (connection of the cover of the cell 'and face 10.- top of the cover) during the positioning of the intervention boot,

  adjustment of the desired application force of the connection
