Abstract

Le dispositif s'applique au raccordement de deux enceintes (12, 16) comprenant chacune une porte (20, 26) obturant une ouverture (22, 28) formée dans une bride (24, 30). L'une (20) des portes supporte un organe de commande rotatif (36) présentant trois séries de rainures formant cames (42a, 42b, 42c). Des leviers en forme de V (46a, 46b, 46c) articulés sur les portes (20, 26) coopérent simultanément avec les rainures et avec des pènes (50a, 50b, 50c), pour déplacer ces derniers entre des positions de verrouillage et de déverrouillage sous l'effet de la rotation de l'organe 36. La configuration des rainures (42a, 42b, 42c) permet de commander les verrouillages des portes entre elles et sur les brides de façon séquentielle. De préférence, les pènes sont inclinés dans le sens favorisant l'étanchéité.The device applies to the connection of two speakers (12, 16) each comprising a door (20, 26) closing an opening (22, 28) formed in a flange (24, 30).

Description

La présente invention, due à la collaboration de MM. Dabernard et Maire de la société USSI et de Monsieur Lorenzelli de la COGEMA, se rapporte à un dispositif permettant de raccorder de façon étanche deux enceintes de confinement, afin de transférer des produits ou des matériels entre ces enceintes tout en préservant leur confinement vis-à-vis de l'atmosphère externe.The present invention, due to the collaboration of MM. Dabernard and Mayor of the company USSI and of Mr. Lorenzelli of COGEMA, relates to a device making it possible to tightly connect two confinement enclosures, in order to transfer products or materials between these enclosures while preserving their confinement vis-à-vis -vis of the external atmosphere.

Des dispositifs de ce type sont utilisés couramment dans de nombreux secteurs de l'industrie et de la recherche, pratiquement à chaque fois qu'il est nécessaire d'isoler une zone déterminée à l'intérieur d'une enceinte de confinement, soit en raison du caractère dangereux ou contaminant de l'atmosphère ou des produits contenus dans cette zone, soit au contraire parce que l'atmosphère stérile contenue dans cette zone risque d'être contaminée par l'air ambiant De telles situations se présentent notamment dans les domaines nucléaires, pharmaceutiques et médicaux.Devices of this type are commonly used in many sectors of industry and research, practically whenever it is necessary to isolate a specific area inside a containment, either due of the dangerous or contaminating nature of the atmosphere or of the products contained in this zone, or on the contrary because the sterile atmosphere contained in this zone risks being contaminated by the ambient air Such situations arise in particular in the nuclear fields , pharmaceutical and medical.

Le brevet français n°2040616 illustre un dispositif de transfert étanche à double porte connu, constitué de deux portes qui obturent deux ouvertures formées respectivement dans chacune des enceintes, à l'intérieur d'une bride solidaire de la paroi de l'enceinte correspondante. Les portes et les brides sont réalisées de telle sorte que, les brides étant accostées l'une à l'autre, les deux portes peuvent être solidarisées sous la forme d'une double porte dont l'ouverture met en communication les volumes internes à chacune des enceintes. Ces dispositifs comprennent en outre deux joints d'étanchéité annulaires montés respectivement sur la porte de l'une des enceintes et sur la bride de l'autre enceinte. Ces joints sont disposés de telle sorte que la mise en oeuvre du dispositif s'effectue à la fois sans que l'atmosphère externe emprisonnée entre les deux portes communique avec l'atmosphère interne des enceintes et sans que l'ouverture de la double porte ait pour effet de rompre l'étanchéité entre l'atmosphère interne des enceintes et l'atmosphère externe.French patent n ° 2040616 illustrates a sealed transfer device with known double door, consisting of two doors which close two openings formed respectively in each of the enclosures, inside a flange secured to the wall of the corresponding enclosure. The doors and the flanges are made in such a way that, the flanges being accosted to each other, the two doors can be secured in the form of a double door, the opening of which connects the internal volumes to each speaker. These devices also include two annular seals mounted respectively on the door of one of the enclosures and on the flange of the other enclosure. These joints are arranged so that the implementation of the device is carried out both without the external atmosphere trapped between the two doors communicating with the internal atmosphere of the enclosures and without the opening of the double door having i t has the effect of breaking the seal between the internal atmosphere of the enclosures and the external atmosphere.

Dans les dispositifs de raccordement existants, et comme l'illustre le brevet cité précédemment, la fermeture de chacune des portes est le plus souvent réalisée par un mécanisme à baïonnette. Un tel mécanisme impose une rotation des portes aussi bien lors de leur ouverture que lors de leur fermeture. Sur une partie au moins de cette rotation, les joints d'étanchéité annulaires frottent contre la surface métallique sur laquelle ils sont normalement appliqués lorsque les portes sont fermées. Le matériau constituant les joints étant un matériau élastomère, ce frottement a pour effet d'en endommager la surface et, par conséquent, l'étanchéité. Ces inconvénients sont accrus lorsque le dispositif est soumis à des manutentions systématiques, comme c'est notamment le cas lorsqu'il est inséré dans une installation nécessitant des manipulations fréquentes.In existing connection devices, and as illustrated by the patent cited above, the closing of each of the doors is most often carried out by a bayonet mechanism. Such a mechanism requires rotation of the doors both when they open and when they are closed. On at least part of this rotation, the annular seals rub against the metal surface to which they are normally applied when the doors are closed. The material constituting the seals being an elastomeric material, this friction has the effect of damaging the surface and, consequently, the seal. These drawbacks are increased when the device is subjected to systematic handling, as is particularly the case when it is inserted in an installation requiring frequent handling.

La présente invention a précisément pour objet un dispositif pour le raccordement étanche de deux enceintes ne présentant pas les inconvénients des dispositifs connus et pouvant notamment être utilisé de façon' systématique, dans des installations de grandes dimensions, ce dispositif pouvant en outre résister sans dommage à des efforts axiaux importants.The present invention specifically relates to a device for the sealed connection of two chambers do not have the drawbacks of the known devices and which can in particular be used so systematic, in large installations, this device being further resist without damage significant axial forces.

A cet effet, et conformément à l'invention, il est proposé un dispositif pour le raccordement étanche d'une première enceinte comprenant une première bride formant une ouverture normalement obturée par une première porte sur une deuxième enceinte comprenant une deuxième bride formant une ouverture normalement obturée par une deuxième porte, ce dispositif comprenant des moyens de verrouillage des portes sur les brides et des portes entre elles, caractérisé en ce que les moyens de verrouillage comprennent :

  • - au moins un organe de commande supporté de façon tournante par la première porte et présentant au moins trois surfaces de came ;
  • - un premier jeu d'au moins trois pênes et un deuxième jeu d'au moins trois pènes aptes à coulisser dans la première porte entre une position rétractée et une position de verrouillage dans laquelle lesdits pènes font saillie dans des évidements formés respectivement dans la première bride et dans la deuxième porte ;
  • - un troisième jeu d'au moins trois pènes aptes à coulisser dans la deuxième porte entre une position rétractée et une position de verrouillage dans laquelle le troisième jeu de pènes fait saillie dans un évidement formé dans la deuxième bride ; et
  • - trois jeux d'au moins trois organes de transmission interposés respectivement entre chaque surface de came et l'un des jeux de pênes, pour déplacer ces derniers entre leurs positions rétractées et de verrouillage sous l'effet d'une rotation de l'organe de commande.
To this end, and in accordance with the invention, a device is proposed for the sealed connection of a first enclosure comprising a first flange forming an opening normally closed by a first door on a second enclosure comprising a second flange forming a normally opening closed by a second door, this device comprising means for locking the doors on the flanges and doors between them, characterized in that the locking means comprise:
  • - at least one control member rotatably supported by the first door and having at least three cam surfaces;
  • - A first set of at least three bolts and a second set of at least three bolts capable of sliding in the first door between a retracted position and a locking position in which said bolts protrude into recesses formed respectively in the first flange and in the second door;
  • - A third set of at least three bolts capable of sliding in the second door between a retracted position and a locking position in which the third set of bolts protrudes into a recess formed in the second flange; and
  • - three sets of at least three transmission members interposed respectively between each cam surface and one of the sets of bolts, to move the latter between their retracted and locking positions under the effect of a rotation of the member control.

Selon un mode de réalisation particulièrement intéressant de l'invention, chacun des pènes est mobile selon une direction située dans un plan contenant l'axe de rotation de l'organe de commande et inclinée dans le sens favorisant l'étanchéité des portes.According to a particularly advantageous embodiment of the invention, each of the bolts is movable in a direction situated in a plane containing the axis of rotation of the control member and inclined in the direction favoring the sealing of the doors.

De préférence, chacun des organes de transmission comprend un levier en forme de V articulé autour d'un axe orthogonal à l'axe de rotation de l'organe de commande, dont une extrémité est en appui sur l'une des surfaces de came et dont l'extrémité opposée est en appui sur l'un des pènes, les leviers en appui sur le premier et le deuxième jeux de pènes étant articulés sur la première porte alors que les leviers en appui sur le troisième jeu de pênes sont articulés sur la deuxième porte.Preferably, each of the transmission members comprises a V-shaped lever articulated around an axis orthogonal to the axis of rotation of the control member, one end of which bears on one of the cam surfaces and whose opposite end is supported on one of the bolts, the levers supported on the first and second sets of bolts being articulated on the first door while the levers supported on the third set of bolts are articulated on the second door.

Conformément à un autre aspect de l'invention, l'une des brides, dite bride externe, se prolonge autour de l'autre bride, dite bride interne, le dispositif comprenant de plus des moyens de verrouillage des brides entre elles, ces moyens comprenant au moins un quatrième jeu d'au moins trois pènes aptes à coulisser dans la bride externe entre une position rétractée et une position de verrouillage dans laquelle le quatrième jeu de pênes fait saillie dans un évidement formé dans la bride interne, et des moyens pour déplacer ce quatrième jeu de pênes entre sa position rétractée et sa position de verrouillage.According to another aspect of the invention, one of the flanges, called the external flange, extends around the other flange, called the internal flange, the device further comprising means for locking the flanges together, these means comprising at least a fourth set of at least three bolts capable of sliding in the external flange between a retracted position and a locking position in which the fourth set of bolts protrudes into a recess formed in the internal flange, and means for moving this fourth set of bolts between its retracted position and its locking position.

A preferred embodiment of the invention will now be described, by way of nonlimiting example, with reference to the appended drawings in which:
  • FIG. 1 is a view in longitudinal section of a sealed connection device produced in accordance with the teachings of the invention,
  • FIG. 2 is a view along arrow F in FIG. 1 of the control member in which the cam surfaces used to control the locking and unlocking of the device are produced, and
  • - Figure 3 is a side view, in partial longitudinal section, of an installation used to remotely operate the device of Figure 1 and to ensure the gripping and handling of the double door of this device.

Dans l'exemple de réalisation représenté sur les figures, le dispositif de raccordement 10 selon l'invention est disposé entre une enceinte statique 12 définissant un volume de travail interne 14 de dimensions relativement grandes et un conteneur mobile 16 définissant un volume interne 18 de dimensions relativement petites. Seules les parties de l'enceinte 12 et du conteneur 16 dans lesquelles est situé le dispositif de raccordement 10 sont représentées sur la figure 1.In the embodiment shown in the figures, the connection device 10 according to the invention is arranged between a static enclosure 12 defining an internal working volume 14 of relatively large dimensions and a mobile container 16 defining an internal volume 18 of dimensions relatively small. Only the parts of the enclosure 12 and of the container 16 in which the connection device 10 is located are shown in FIG. 1.

De façon connue, le dispositif de raccordement 10 comprend une première porte 20 obturant de façon étanche une ouverture circulaire 22 formée dans une bride 24 solidaire de la paroi de l'enceinte 12. De façon comparable, le dispositif 10 comprend une deuxième porte 26 obturant de façon étanche une ouverture circulaire 28 formée dans une bride 30 solidaire de la paroi du conteneur 16.In known manner, the connection device 10 comprises a first door 20 sealingly sealing a circular opening 22 formed in a flange 24 secured to the wall of the enclosure 12. In a comparable manner, the device 10 comprises a second door 26 sealing a circular opening 28 formed in a flange 30 integral with the wall of the container 16.

De façon plus précise, la bride 24 de l'enceinte 12 se présente sous la forme d'une jupe qui fait saillie vers l'extérieur de l'enceinte et sur laquelle peut venir s'emboîter l'extrémité de la bride 30 du conteneur 16. Les brides 24 et 30 constituent ainsi respectivement une bride interne et une bride externe. Afin de permettre l'emboîtement de la bride interne 24 dans l'extrémité de la bride 30, la porte 26 est placée en retrait à l'intérieur de cette dernière. A cet effet, la porte 26 présente une collerette externe qui vient en appui sur un épaulement 31 formé dans l'ouverture 28. Le démontage de la porte 20 s'effectuant vers l'intérieur de l'enceinte 12, une collerette interne 25 est également formée à l'extrémité de la bride 24 pour servir de butée à la porte 20.More specifically, the flange 24 of the enclosure 12 is in the form of a skirt which projects towards the outside of the enclosure and onto which the end of the flange 30 of the container can fit. 16. The flanges 24 and 30 thus constitute respectively an internal flange and an external flange. In order to allow the internal flange 24 to fit into the end of the flange 30, the door 26 is set back inside the latter. To this end, the door 26 has an external flange which comes to bear on a shoulder 31 formed in the opening 28. The dismantling of the door 20 takes place towards the inside of the enclosure 12, an internal flange 25 is also formed at the end of the flange 24 to serve as a stop for the door 20.

De façon connue, la porte 20 supporte à sa périphérie un joint annulaire 32 en matériau élastomère, dont la face périphérique externe de forme tronconique est normalement en appui étanche contre une surface complémentaire formée à l'intérieur de la collerette 25. Une autre face active du joint 32 est normalement disposée dans le même plan radial que la face plane d'extrémité de la bride 24, lorsque la porte 20 est verrouillée dans cette dernière.In known manner, the door 20 supports at its periphery an annular seal 32 made of elastomeric material, the external peripheral face of frustoconical shape is normally in sealed abutment against a complementary surface formed inside the flange 25. Another active face of the seal 32 is normally disposed in the same radial plane as the flat end face of the flange 24, when the door 20 is locked in the latter.

De façon comparable, un joint torique 34 réalisé en un matériau élastomère est fixé à l'intérieur de la bride 30 du conteneur, en appui contre l'épaulement 31. La face périphérique interne tronconique de ce joint 34 est normalement en contact étanche avec une surface complémentaire formée à la périphérie de la porte 26. De plus, une autre face active du joint 34 est normalement disposée dans le même plan radial que la face plane d'extrémité de la porte 26, lorsque celle-ci est verrouillée à l'intérieur de la bride 30.Similarly, an O-ring 34 made of an elastomeric material is fixed inside the flange 30 of the container, bearing against the shoulder 31. The frustoconical internal peripheral face of this seal 34 is normally in tight contact with a complementary surface formed at the periphery of the door 26. In addition, another active face of the seal 34 is normally arranged in the same radial plane as the flat end face of the door 26, when the latter is locked to the inside of flange 30.

Comme l'illustre la figure 1, lorsque la bride 30 du conteneur est emmanchée sur la bride 24 de l'enceinte, les faces planes d'extrémité de ces deux brides viennent respectivement en appui sur les faces actives radiales des joints 34 et 32. Les faces actives tronconiques de ces joints se trouvent alors dans le prolongement l'une de l'autre. Dans cette position, les ouvertures circulaires 22 et 28 sont alignées selon un même axe XX'.As illustrated in FIG. 1, when the flange 30 of the container is fitted onto the flange 24 of the enclosure, the flat end faces of these two flanges come to bear respectively on the radial active faces of the seals 34 and 32. The frustoconical active faces of these joints are then in the extension of one another. In this position, the circular openings 22 and 28 are aligned along the same axis XX '.

Conformément à l'invention, le verrouillage et le déverrouillage des portes dans les brides qui leur correspondent et le verrouillage et le déverrouillage des portes entre elles sont commandés par un organe 36 monté de façon tournante dans la porte 20 autour de l'axe XX'. Cet organe 36 se compose d'une tige de commande 36a qui traverse de part en part une première partie 20a de la porte 20 située du côté du volume interne 14 de l'enceinte 12. La tige 36a est supportée de façon tournante par cette partie 20a de la porte, par l'intermédiaire de roulements 38.According to the invention, the locking and unlocking of the doors in the corresponding flanges and the locking and unlocking of the doors between them are controlled by a member 36 rotatably mounted in the door 20 around the axis XX ' . This member 36 consists of a control rod 36a which passes right through a first part 20a of the door 20 located on the side of the internal volume 14 of the enclosure 12. The rod 36a is rotatably supported by this part 20a of the door, by means of bearings 38.

La tige 36a est solidaire d'une pièce massive 36b logée à l'intérieur de la porte 20, dans un espace ménagé entre la partie 20a et une deuxième partie 20b de cette porte. Avantageusement, cette partie 20b peut comporter un pion de centrage 40 coopérant de façon tournante avec la pièce massive 36b, par l'intermédiaire d'un troisième roulement 38.The rod 36a is integral with a solid part 36b housed inside the door 20, in a space formed between the part 20a and a second part 20b of this door. Advantageously, this part 20b may comprise a centering pin 40 cooperating in a rotary manner with the solid part 36b, by means of a third bearing 38.

Afin de commander lors de sa rotation le verrouillage et le déverrouillage des portes entre elles et sur les brides qui leur correspondent, la pièce massive 36b comporte trois séries de surfaces de cames constituées par des rainures 42a, 42b et 42c sensiblement en arcs de cercles. Comme l'illustrent les figures 1 et 2, chaque série de rainures comprend trois rainures régulièrement réparties autour de l'axe XX', chaque rainure présentant une longueur correspondant à une rotation d'environ 90° de la pièce 36b.In order to control during its rotation the locking and unlocking of the doors between them and on the flanges which correspond to them, the solid part 36b comprises three series of cam surfaces formed by grooves 42a, 42b and 42c substantially in arcs of circles. As illustrated in FIGS. 1 and 2, each series of grooves comprises three grooves regularly distributed around the axis XX ', each groove having a length corresponding to a rotation of approximately 90 ° of the part 36b.

Sur cet arc de cercle de 90°, la partie formant came est limitée à environ 30°. En d'autres termes, le rayon des rainures d'une série donnée est constant sur un arc de cercle d'environ 60° et varie sur un arc de cercle d'environ 30°. De plus, les parties formant came de chaque série de rainures 42a, 42b, 42c sont décalées par rapport aux parties formant came des autres séries, de telle sorte que la rotation de l'organe 36 a pour effet de commander successivement chacun des moyens de verrouillage du dispositif. Une commande séquentielle de ces moyens de verrouillage est ainsi réalisée.On this 90 ° circular arc, the cam portion is limited to approximately 30 °. In other words, the radius of the grooves of a given series is constant over an arc of about 60 ° and varies over an arc of about 30 °. In addition, the cam parts of each series of grooves 42a, 42b, 42c are offset from the cam parts of the other series, so that the rotation of the member 36 has the effect of successively controlling each of the means of locking the device. A sequential control of these locking means is thus achieved.

En pratique, la première série de rainures 42a est formée sur la face plane de la partie 36b tournée vers la partie 20a de la porte 20, alors que les deuxième et troisième séries de rainures 42b et 42c sont formées sur la face plane de la partie 36b tournée vers la partie 20b de la porte 20.In practice, the first series of grooves 42a is formed on the flat face of the part 36b facing the part 20a of the door 20, while the second and third series of grooves 42b and 42c are formed on the flat face of the part 36b facing part 20b of door 20.

Chacune des séries de rainures formant cames 42a, 42b et 42c commande une série ou jeu de trois pènes 50a, 50b, et 50c assurant respectivement les verrouillages de la porte 20 sur la bride 24, de la porte 20 sur la porte 26 et de la porte 26 sur la bride 30. Les trois pènes de chaque série de pènes 50a, 50b et 50c sont régulièrement répartis à 120° les uns des autres autour de l'axe XX'.Each of the series of grooves forming cams 42a, 42b and 42c controls a series or set of three bolts 50a, 50b, and 50c ensuring respectively the locks of the door 20 on the flange 24, of the door 20 on the door 26 and of the door 26 on the flange 30. The three bolts of each series of bolts 50a, 50b and 50c are regularly distributed at 120 ° from each other around the axis XX '.

Les trois pènes 50a assurant le verrouillage de la porte 20 sur la bride 24 sont montés de façon coulissante dans la partie 20a de la porte 20, pour se déplacer entre une position de déverrouillage ou d'ouverture dans laquelle leur extrémité est rétractée et affleure la surface périphérique externe de la porte 20, et une position de verrouillage ou de fermeture dans laquelle l'extrémité des pènes fait saillie audelà de cette surface dans une gorge annulaire 52a formée à l'intérieur de la bride 24.The three bolts 50a ensuring the locking of the door 20 on the flange 24 are slidably mounted in the part 20a of the door 20, to move between an unlocking or opening position in which their end is retracted and is flush with the external peripheral surface of the door 20, and a locking or closing position in which the end of the bolts protrudes beyond this surface in an annular groove 52a formed inside the flange 24.

De façon comparable, les trois pènes 50b assurant le verrouillage de la porte 20 sur la porte 26 sont montés de façon coulissante dans la partie 20b de la porte 20, pour se déplacer entre une position de déverrouillage ou d'ouverture dans laquelle leur extrémité est rétractée et affleure une partie de la surface périphérique externe de la porte 20 qui pénètre dans une partie annulaire de la porte 26, et une position de verrouillage ou de fermeture dans laquelle l'extrémité des pènes fait saillie au-delà de cette surface dans une gorge annulaire 52b formée à l'intérieur de la partie annulaire de la porte 26.Similarly, the three bolts 50b ensuring the locking of the door 20 on the door 26 are slidably mounted in the part 20b of the door 20, to move between an unlocking or opening position in which their end is retracted and flush with a part of the external peripheral surface of the door 20 which enters an annular part of the door 26, and a locking or closing position in which the end of the bolts protrudes beyond this surface in a annular groove 52b formed inside the annular part of the door 26.

De même, les trois pènes 50c assurant le verrouillage de la porte 26 sur la bride 30 sont montés de façon coulissante dans la partie annulaire de la porte 26, pour se déplacer entre une position de déverrouillage ou d'ouverture dans laquelle leur extrémité est rétractée et affleure la surface externe de cette partie annulaire, et une position de verrouillage ou de fermeture dans laquelle l'extrémité des pènes fait saillie au-delà de cette surface dans une gorge annulaire 52c formée à l'intérieur de la bride 30. Le déplacement de chacun des pênes s'effectue dans un plan radial passant par l'axe XX'.Similarly, the three bolts 50c ensuring the locking of the door 26 on the flange 30 are slidably mounted in the annular part of the door 26, to move between an unlocking or opening position in which their end is retracted and is flush with the external surface of this annular part, and a locking or closing position in which the end of the bolts protrudes beyond this surface in an annular groove 52c formed inside the flange 30. The displacement of each of the bolts is carried out in a radial plane passing through the axis XX '.

Chacun des pênes 50a, 50b et 50c est sollicité élastiquement vers sa position de verrouillage par un ressort de compression 54a, 54b et 54c, respectivement.Each of the bolts 50a, 50b and 50c is urged elastically towards its locking position by a compression spring 54a, 54b and 54c, respectively.

De plus, l'étanchéité des portes 20 et 26 est préservée par des joints toriques (ou par des soufflets) 55a, 55b et 55c interposés respectivement entre chacun des pènes 50a, 50b et 50c et la porte dans laquelle il coulisse.In addition, the tightness of the doors 20 and 26 is preserved by O-rings (or by bellows) 55a, 55b and 55c interposed respectively between each of the bolts 50a, 50b and 50c and the door in which it slides.

De préférence, afin d'améliorer la résistance du dispositif selon l'invention à des efforts importants appliqués selon l'axe XX' dans le sens de l'ouverture des portes 20 et 26 considérées isolément ou de la séparation de ces deux portes lorsqu'elles sont verrouillées par les pènes 50b, les pènes 50a, 50b et 50c sont inclinés selon un angle d'environ 45° dans le sens s'opposant à cette ouverture ou à cette séparation. Dans le mode de réalisation de la figure 1 dans lequel l'ouverture et la séparation des portes s'effectuant vers l'intérieur de l'enceinte 12, les pènes 50a, 50b et 50c sont donc inclinés d'environ 45° vers l'intérieur de cette enceinte, par rapport à l'axe XX'.Preferably, in order to improve the resistance of the device according to the invention to significant forces applied along the axis XX 'in the direction of the opening of the doors 20 and 26 considered in isolation or of the separation of these two doors when they are locked by the bolts 50b, the bolts 50a, 50b and 50c are inclined at an angle of approximately 45 ° in the direction opposing this opening or this separation. In the embodiment of FIG. 1 in which the opening and separation of the doors takes place towards the interior of the enclosure 12, the bolts 50a, 50b and 50c are therefore inclined by about 45 ° towards the inside this enclosure, relative to the axis XX '.

Etant donné que l'extrémité des pênes 50a, 50b et 50c apte à faire saillie dans les gorges 52a, 52b et 52c respectivement se présente sous la forme d'une tige cylindrique à bout chanfreiné, les gorges 52a, 52b et 52c présentent alors en section des formes triangulaires.Since the end of the bolts 50a, 50b and 50c capable of projecting into the grooves 52a, 52b and 52c respectively is in the form of a cylindrical rod with a chamfered end, the grooves 52a, 52b and 52c then have section of triangular shapes.

Afin de déplacer les pènes 50a, 50b et 50c entre leurs positions de verrouillage et de déverrouillage, on interpose entre chacune des rainures formant came 52a, 52b et 52c et le pêne correspondant un organe de transmission de mouvement 46a, 46b et 46c, respectivement.In order to move the bolts 50a, 50b and 50c between their locking and unlocking positions, a motion transmission member 46a, 46b and 46c is interposed between each of the cam grooves 52a, 52b and 52c and the corresponding bolt.

Chacun des organes 46a, 46b et 46c se présente sous la forme d'un levier à deux branches en forme de V monté pivotant dans sa partie médiane sur un axe 48a, 48b et 48c, respectivement, disposé selon une direction orthogonale à l'axe XX'. Les leviers 46a et 46b sont respectivement supportés de façon pivotante par les parties 20a et 20b de la porte 20, alors que les leviers 46c sont supportés de façon pivotante par la porte 26.Each of the members 46a, 46b and 46c is in the form of a lever with two V-shaped branches mounted to pivot in its middle part on an axis 48a, 48b and 48c, respectively, arranged in a direction orthogonal to the axis XX '. The levers 46a and 46b are respectively pivotally supported by the parts 20a and 20b of the door 20, while the levers 46c are pivotally supported by the door 26.

Une première branche de chacun des leviers 46a, 46b et 46c est orientée sensiblement parallèlement à l'axe XX' et porte à son extrémité un galet 44a, 44b et 44c qui vient se loger dans la rainure formant came correspondante 42a, 42b et 42c. Comme l'illustre la figure 1, des trous 56 formés dans la partie 20b de la porte 20 permettent le passage de la première branche de chacun des leviers 46b et 46c.A first branch of each of the levers 4 6a, 46b and 46c is oriented substantially parallel to the axis XX 'and carries at its end a roller 44a, 44b and 44c which is housed in the corresponding cam groove 42a, 42b and 42c . As illustrated in FIG. 1, holes 56 formed in the part 20b of the door 20 allow the passage of the first branch of each of the levers 46b and 46c.

La deuxième branche de chacun des leviers 46a, 46b et 46c est orientée selon une direction sensiblement perpendiculaire au pêne 50a, 50b et 50c qui lui correspond. L'extrémité de chacune de ces deuxièmes branches forme deux surfaces d'appui convexes opposées qui coopèrent de manière positive, dans les deux sens, avec les bords d'une entaille formée dans le pêne correspondant, de façon à induire un déplacement axial de ce dernier, sous l'effet d'un pivotement du levier.The second branch of each of the levers 46a, 46b and 46c is oriented in a direction substantially perpendicular to the bolt 50a, 50b and 50c which corresponds to it. The end of each of these second branches forms two opposite convex bearing surfaces which cooperate positively, in both directions, with the edges of a notch formed in the corresponding bolt, so as to induce an axial displacement of this last, under the effect of a pivoting of the lever.

Dans le cas où les pènes 50a, 50b et 50c sont inclinés d'environ 45° vers l'intérieur de l'enceinte 12, les deux branches de chacun des trois leviers 46a font entre elles un angle d'environ 45°, alors que les deux branches de chacun des leviers 46b et 46c font entre elles un angle d'environ 135°.In the case where the bolts 50a, 50b and 50c are inclined by about 45 ° towards the inside of the enclosure 12, the two branches of each of the three levers 46a form an angle of about 45 ° between them, while the two branches of each of the levers 46b and 46c form an angle of about 135 ° between them.

Grâce à la structure qui vient d'être décrite, les opérations de verrouillage et de déverrouillage des portes entre elles et sur les brides sont réalisées sans aucune rotation au niveau des joints, ce qui permet de préserver le bon fonctionnement de ceux-ci même en cas d'usage intensif. De plus, la conception du mécanisme de verrouillage est telle que le dispositif reste fiable même lorsqu'il est de grande dimension et soumis à des efforts axiaux importants.Thanks to the structure which has just been described, the locking and unlocking operations of the doors between them and on the flanges are carried out without any rotation at the joints, which makes it possible to preserve the proper functioning of these even in intensive use case. In addition, the design of the locking mechanism is such that the device remains reliable even when it is large and subjected to significant axial forces.

En outre, le mode de réalisation particulier qui vient d'être décrit présente l'avantage supplémentaire de réaliser une commande séquentielle des différentes opérations de verrouillage et de déverrouillage. Ainsi, la disposition particulière des cames représentée sur la figure 2 permet après accostage de commander successivement lors de la rotation de l'organe 36 le déverrouillage de la porte 26 du conteneur, puis le verrouillage de la porte 20 sur la porte 26 et enfin le déverrouillage de la porte 20 par rapport à l'enceinte. Dans une autre configuration non représentée, les deux premières opérations pourraient à volonté être inversées par une simple modification des surfaces de cames formées par les rainures 42a, 42b et 42c. Bien entendu, ce caractère séquentiel des opérations se retrouve dans l'ordre inverse lorsqu'on désaccouple le conteneur de l'enceinte. Il présente l'avantage que l'on connaît à tout moment la configuration exacte du dispositif.In addition, the particular embodiment which has just been described has the additional advantage of carrying out a sequential control of the various locking and unlocking operations. Thus, the particular arrangement of the cams shown in FIG. 2 allows after docking to successively control during the rotation of the member 36 the unlocking of the door 26 of the container, then the locking of the door 20 on the door 26 and finally the unlocking of the door 20 relative to the enclosure. In another configuration not shown, the first two operations could be reversed at will by a simple modification of the cam surfaces formed by the grooves 42a, 42b and 42c. Of course, this sequential nature of the operations is found in the reverse order when the container is uncoupled from the enclosure. It has the advantage that the exact configuration of the device is known at all times.

Dans le mode de réalisation représenté sur la figure 1, le dispositif comprend de plus des moyens pour verrouiller la bride 30 du conteneur 16 sur la bride 24 de l'enceinte 12.In the embodiment shown in FIG. 1, the device further comprises means for locking the flange 30 of the container 16 on the flange 24 of the enclosure 12.

Ces derniers moyens sont réalisés de façon analogue aux autres moyens de verrouillage. Ils comprennent au moins trois pènes 50d disposés à 120° les uns des autres autour de l'axe XX'. Ces pènes sont montés de façon coulissante dans la bride 30, afin de pouvoir se déplacer entre une position de déverrouillage dans laquelle ils sont rétractés et affleurent la face périphérique interne de la bride 30 et une position de verrouillage dans laquelle ils font saillie au-delà de cette périphérie dans une gorge annulaire 52d formée dans la périphérie externe de la bride 24. La direction de déplacement de chacun des pènes 50d est contenue dans un plan passant par l'axe XX' et elle est inclinée de préférence sensiblement à 45° par rapport à cet axe, vers l'intérieur de l'enceinte 12, de façon à s'opposer à tout effort tendant à séparer le conteneur 16 de l'enceinte 12. Pour tenir compte de l'inclinaison des pênes 50d, la gorge annulaire 52d présente une section triangulaire. Un ressort 54d sollicite chacun des pênes 50d vers sa position de verrouillage.These latter means are produced analogously to the other locking means. They comprise at least three bolts 50d arranged at 120 ° from each other around the axis XX '. These bolts are slidably mounted in the flange 30, in order to be able to move between an unlocking position in which they are retracted and are flush with the internal peripheral face of the flange 30 and a locking position in which they protrude beyond of this periphery in an annular groove 52d formed in the external periphery of the flange 24. The direction of movement of each of the bolts 50d is contained in a plane passing through the axis XX 'and it is preferably inclined substantially at 45 ° by relative to this axis, towards the inside of the enclosure 12, so as to oppose any effort tending to separate the container 16 from the enclosure 12. To take account of the inclination of the bolts 50d, the annular groove 52d has a triangular section. A spring 54d biases each of the bolts 50d towards its locking position.

La commande du déplacement de chacun des pènes 50d est effectuée par l'intermédiaire d'un levier 46d en forme de V dont la partie centrale est articulée sur la bride 30 par un axe 48d. Une première branche de chacun des leviers 46d est disposée sensiblement parallèlement à l'axe XX' et porte à son extrémité un galet 44d qui vient se loger dans une fourchette de commande 58 supportée par la paroi de l'enceinte 12 lorsque le conteneur 16 est accosté sur cette dernière.The movement of each of the bolts 50d is controlled by means of a V-shaped lever 46d, the central part of which is articulated on the flange 30 by an axis 48d. A first branch of each of the levers 46d is disposed substantially parallel to the axis XX 'and carries at its end a roller 4 4d which is housed in a control fork 58 supported by the wall of the enclosure 12 when the container 16 is approached on the latter.

La deuxième branche de chacun des leviers 46d est disposée sensiblement perpendiculairement au pêne 50d correspondant et son extrémité présente deux surfaces convexes opposées qui viennent en appui sur les bords d'une encoche formée dans ce pène. Le basculement des leviers 46d autour de leurs axes 48d a ainsi pour effet de déplacer les pènes 50d entre leurs positions de verrouillage et de déverrouillage.The second branch of each of the levers 46d is arranged substantially perpendicular to the corresponding bolt 50d and its end has two opposite convex surfaces which come to bear on the edges a notch formed in this bolt. The tilting of the levers 46d around their axes 48d thus has the effect of displacing the bolts 50d between their locking and unlocking positions.

La commande de ce basculement est obtenue en déplaçant les fourchettes 58 selon une direction radiale par rapport l'axe XX'. Ce déplacement des fourchettes 58 peut être réalisé par tout moyen et notamment à l'aide d'une came tournante 59 actionnée par un vérin (non représenté). Les pênes 50d sont ainsi commandés simultanément.The control of this tilting is obtained by moving the forks 58 in a radial direction relative to the axis XX '. This displacement of the forks 58 can be achieved by any means and in particular using a rotating cam 59 actuated by a jack (not shown). The bolts 50d are thus controlled simultaneously.

Lorsque les dimensions et le poids des portes le permettent, la manoeuvre de l'organe 36 commandant les moyens de verrouillage peut être réalisée simplement à l'aide d'un volant ou d'un levier solidarisé de l'extrémité de l'arbre 36a située à l'intérieur de l'enceinte 12.When the dimensions and the weight of the doors allow it, the operation of the member 36 controlling the locking means can be carried out simply by means of a steering wheel or a lever secured to the end of the shaft 36a. located inside enclosure 12.

Dans le mode de réalisation représenté, la manoeuvre de l'organe 36 est réalisée à distance l'aide d'un dispositif 60 implanté à demeure dans l'enceinte 12 et servant également à assurer la préhension et la manutention de la double porte que constituent les portes 20 et 26 lorsqu'elles sont verrouillées l'une sur l'autre. Ce dispositif 60 va maintenant être décrit en se référant à la figure 3.In the embodiment shown, the operation of the member 36 is carried out remotely using a device 60 permanently installed in the enclosure 12 and also serving to ensure the gripping and handling of the double door that constitute the doors 20 and 26 when they are locked one on the other. This device 60 will now be described with reference to FIG. 3.

Le dispositif de manoeuvre 60 comprend principalement une tige centrale 62, un tube intermédiaire 64 et un tube externe 66 disposés coaxialement selon l'axe XX' à l'intérieur du volume 14. Dans le mode de réalisation représenté sur la figure 3, ces trois pièces coaxiales traversent la cloison de l'enceinte 12 placée en regard de l'ouverture 22 obturée par la porte 20, de telle sorte que les moteurs et les mécanismes assurant la commande de ces trois pièces sont placés à l'extérieur de l'enceinte 12, ce qui en facilite la maintenance.The operating device 60 mainly comprises a central rod 62, an intermediate tube 64 and an external tube 66 arranged coaxially along the axis XX 'inside the volume 14. In the embodiment shown in FIG. 3, these three coaxial parts pass through the partition of the enclosure 12 placed opposite the opening 22 closed by the door 20, so that the motors and the mechanisms ensuring the control of these three parts are placed outside the enclosure 12, which facilitates maintenance.

De façon plus précise, le tube externe 66 traverse de façon coulissante parallèlement à l'axe XX' une pièce de supportage 68 fixée à la paroi de l'enceinte 12, à l'extérieur de celle-ci. La pièce de supportage 68 porte un premier ensemble motoréducteur 70 qui entraîne en rotation une vis sans fin 72 d'axe parallèle à l'axe du tube 66, par l'intermédiaire d'une chaîne de transmission 74 ou de tout mécanisme équivalent. Un écrou 76 solidaire de l'extrémité du tube 66 placée l'extérieur de l'enceinte 12 est monté sur la vis sans fin 72. Ainsi, la mise en oeuvre de l'ensemble motoréducteur 70 a pour effet de déplacer le tube externe 66 parallèlement à l'axe XX' dans l'un ou l'autre sens.More specifically, the outer tube 66 slides slidably parallel to the axis XX 'a support piece 68 fixed to the wall of the enclosure 12, outside of the latter. The support piece 68 carries a first geared motor assembly 70 which rotates an endless screw 72 with an axis parallel to the axis of the tube 66, via a transmission chain 74 or any equivalent mechanism. A nut 76 secured to the end of the tube 66 placed outside the enclosure 12 is mounted on the endless screw 72. Thus, the implementation of the gearmotor assembly 70 has the effect of displacing the external tube 66 parallel to the axis XX 'in either direction.

Le tube intermédiaire 64 est supporté de façon tournante à l'intérieur du tube 66 par l'intermédiaire de roulements 78. L'entraînement en rotation du tube 64 à l'intérieur du tube 66 est effectué par un deuxième ensemble motoréducteur 80 monté sur une platine 82 fixée à l'extrémité du tube 66 placé à l'extérieur de l'enceinte 12. A cet effet, l'arbre de sortie de l'ensemble motoréducteur 80 porte un pignon 84 qui vient s'engréner sur une roue dentée 86 solidaire de l'extrémité du tube 64 placée à l'extérieur de l'enceinte 12.The intermediate tube 6 4 is rotatably supported inside the tube 66 by means of bearings 78. The rotation drive of the tube 64 inside the tube 66 is carried out by a second geared motor assembly 80 mounted on a plate 82 fixed to the end of the tube 66 placed outside the enclosure 12. For this purpose, the output shaft of the geared motor assembly 80 carries a pinion 84 which engages on a toothed wheel 86 secured to the end of the tube 64 placed outside the enclosure 12.

A son extrémité inférieure, le tube 66 supporte une tête de préhension 88. Cette tête 88 est munie dans sa partie périphérique de trois axes 90 parallèles à l'axe XX' et portant à leurs extrémités des loquets 92 aptes à venir se loger sous une couronne de préhension 94 (figure 1) formée à cet effet sur la partie 20a de la porte 20. Chacun des axes 90 porte un pignon 96 qui vient s'engrener sur une roue dentée 98 solidaire de l'extrémité inférieure du tube 64. Ainsi, la mise en oeuvre de l'ensemble motoréducteur 80 a pour effet de déplacer les loquets 92 entre une position de préhension dans laquelle ils sont placés en-dessous de la couronne 94 et une position de repos ou d'attente dans laquelle ils sont dégagés de cette couronne.At its lower end, the tube 66 supports a gripping head 88. This head 88 is provided in its peripheral part with three axes 90 parallel to the axis XX 'and carrying at their ends latches 92 capable of being housed under a gripping ring 94 (Figure 1) formed for this purpose on the part 20a of the door 20. Each of the axes 90 carries a pinion 96 which engages on a toothed wheel 98 secured to the lower end of the tube 64. Thus , the implementation of the gearmotor assembly 80 has the effect of moving the latches 92 between a gripping position in which they are placed below the crown 94 and a rest or waiting position in which they are released of this crown.

Un pion de centrage 100 (figure 1) est monté sur la couronne 94 et vient se loger dans un évidement correspondant formé dans la tête de préhension 88.A centering pin 100 (FIG. 1) is mounted on the crown 94 and is housed in a corresponding recess formed in the gripping head 88.

L'arbre 62 est supporté de façon tournante par la platine 82 et par la tête de préhension 88, par l'intermédiaire de deux roulements 102. Un troisième ensemble motoréducteur 104 supporté par la platine 82 est en prise directe sur l'extrémité de l'arbre 62 située l'extérieur de l'enceinte 12. L'extrémité opposée de l'arbre 62 comporte un alésage cannelé 106 qui peut venir s'emboîter sur des cannelures complémentaires 108 (figure 1) formées à l'extrémité de la tige 36a de l'organe de commande 36. L'ensemble motoréducteur 104 commande ainsi la rotation de l'organe de commande 36 et, par conséquent, le verrouillage et le déverrouillage des portes entre elles et sur les brides.The shaft 62 is rotatably supported by the plate 82 and by the gripping head 88, by means of two bearings 102. A third gearmotor assembly 104 supported by the plate 82 is in direct engagement on the end of the 'shaft 62 located outside the enclosure 12. The opposite end of the shaft 62 has a grooved bore 106 which can be fitted on complementary grooves 108 (Figure 1) formed at the end of the rod 36a of the control member 36. The gearmotor assembly 104 thus controls the rotation of the control member 36 and, consequently, the locking and unlocking of the doors between them and on the flanges.

De préférence, des soufflets d'étanchéité 108 sont fixés de façon étanche entre chacune des extrémités du tube externe 66 et le support 68, de façon à éviter toute rupture du confinement de l'enceinte 12 à ce niveau.Preferably, sealing bellows 108 are tightly fixed between each of the ends of the outer tube 66 and the support 68, so as to avoid any rupture of the confinement of the enclosure 12 at this level.

Dans sa position de repos, le dispositif 60 est placé en position rétractée sous l'action de l'ensemble motoréducteur 70. La tête de préhension 88 est alors placée au voisinage immédiat de la paroi de l'enceinte 12 sur laquelle est fixé le support 68.In its rest position, the device 60 is placed in the retracted position under the action of the gearmotor assembly 70. The gripping head 88 is then placed in the immediate vicinity of the wall of the enclosure 12 on which the support is fixed 68.

Lorsqu'un conteneur est accosté sur l'enceinte, il est d'abord solidarisé de celle-ci par l'actionnement des pènes de verrouillage 50d (figure 1). La tête de préhension 88 est alors amenée en position de travail par la mise en oeuvre de l'ensemble motoréducteur 70. Dans cette position, qui est représentée sur la figure 3, la mise en oeuvre de l'ensemble motoréducteur 80 a pour effet de faire basculer les loquets 92, assurant ainsi la préhension de la double porte. Les opérations de déverrouillage des deux portes par rapport à leur bride et de verrouillage des bouchons l'un sur l'autre sont ensuite réalisées en actionnant l'ensemble motoréducteur 104. L'ouverture de la double porte peut alors être effectuée en actionnant à nouveau et en sens inverse l'ensemble motoréducteur 70.When a container is docked on the enclosure, it is first secured to the latter by actuation of the locking pins 50d (FIG. 1). The gripping head 88 is then brought into the working position by the use of the gearmotor assembly 70. In this position, which is shown in FIG. 3, the use of the gearmotor assembly 80 has the effect of tilt the latches 92, thus ensuring the gripping of the double door. The operations of unlocking the two doors relative to their flange and locking the plugs on one another are then carried out by actuating the gearmotor assembly 104. The opening of the double door can then be carried out by actuating again and in reverse direction the gearmotor assembly 70.

Lorsqu'on désire séparer le conteneur de l'enceinte, les opérations qui viennent d'être décrites sont effectuées en sens inverse.When it is desired to separate the container from the enclosure, the operations which have just been described are carried out in reverse order.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit à titre d'exemple mais en couvre toutes les variantes. En particulier, on a déjà mentionné précédemment que la manoeuvre de l'organe 36 peut être réalisée directement à l'aide d'un volant ou d'un levier de manoeuvre solidaire de celui-ci. De même, les moyens pour solidariser chacune des brides peuvent être différents des moyens décrits et il est clair que l'invention ne s'applique pas uniquement à l'accostage d'un conteneur sur une enceinte mais couvre de façon générale le raccordement d'enceintes de types et de dimensions quelconques. Enfin, la transmission des mouvements entre les surfaces de cames formées sur l'organe de commande et les pènes assurant les verrouillages peut être réalisée par tout moyen équivalent aux leviers en forme de V décrits.Of course, the invention is not limited to the embodiment which has just been described by way of example but covers all its variants. In particular, it has already been mentioned previously that the operation of the member 36 can be carried out directly using a steering wheel or an operating lever integral with the latter. Likewise, the means for securing each of the flanges may be different from the means described and it is clear that the invention does not only apply to the docking of a container on an enclosure but generally covers the connection of enclosures of any type and size. Finally, the transmission of movements between the cam surfaces formed on the control member and the bolts ensuring the locks can be carried out by any means equivalent to the V-shaped levers described.
