Dans la figure 1, le pivoteur 1 se compose d'une partie gauche 2 supportant la poche 4, et d'une partie droite 3 supportant la poche 5. Les moitiés gauche de la poche 4 et droite de la poche 5 sont représentées en coupe horizontale. Les deux parties 2 et 3 du pivoteur tournent autour d'un axe 7. De part et d'autre du pivoteur sont disposées des passerelles d'accès pour le personnel 8 et 9. Sur la partie en haut à gauche de la figure sont représentés schématiquement l'ensemble des organes de branchement électrique et pneumatique 10 du pivoteur et 11 de la poche 4.

Dans la figure 2, on voit en élévation le berceau 12 du pivoteur de réception de la poche 4 et l'ensemble 10 des organes de branchement électrique et pneumatique du pivoteur, vu selon la flèche II de la figure 1. Cet ensemble est protégé des projections éventuelles d'acier fondu par un capotage en U de tôles épaisses 13, 14, 15 l'entourant sur trois côtés, visible également sur la figure 3.In FIG. 2, the cradle 12 of the pocket receiving pivot 4 is seen in elevation and the assembly 10 of the electrical and pneumatic connection members of the pivot, seen according to arrow II in FIG. 1. This assembly is protected from possible projections of molten steel by a U-shaped cover of thick sheets 13, 14, 15 surrounding it on three sides, also visible in FIG. 3.

Sur la figure 3, à échelle agrandie, on voit l'arrière du vérin d'accouplement 20 des organes de connexion pneumatique, ainsi qu'un dispositif 21 de rappel dans l'axe d'accouplement dans un plan horizontal des connexions, et deux dispositif verticaux 22, 23 de suspension et de rappel dans l'axe réglant l'inclinaison du vérin 20 et des connexions autour de l'axe horizontal.

The reminder device. in the axis 21 is supported on a sheet integral with the side wall of the. cradle of the pivoter by means of an axis 24, and the return devices in the axis 22 and 23 on the upper protective sheet by means of axes 25, 26.

La figure 4 représente à échelle agrandie, avec coupe partielle par un plan horizontal, le détail IV de la figure 1.FIG. 4 shows on an enlarged scale, with partial section through a horizontal plane, the detail IV of FIG. 1.

En face de celle-ci, est disposée la pièce mâle 28 de connexion pneumatique solidaire de la poche 4, et comportant un cône de guidage 44. La pièce 28 est portée par une rotule 29, portée elle-même par une pièce 30 fixée sur la paroi de la poche 4. Elle est protégée des projections d'acier par un capotage en tôle épaisse 31. Le dispositif de rappel dans l'axe 32, s'appuyant sur l'axe 33 solidaire de la tôle 34 fixée sur la paroi de la poche, assure son rappel dans l'axe dans un plan horizontal.We see the pneumatic coupling cylinder 20, the return device in the axis 21 thereof in a horizontal plane by rotation about the vertical axis 21A, as well as the female part 27 of pneumatic connection secured to the pivot. Opposite the latter, there is disposed the male part 28 of pneumatic connection secured to the pocket 4, and comprising a guide cone 44. The part 28 is carried by a ball joint 29, itself carried by a part 30 fixed on the wall of the pocket 4. It is protected from steel projections by a cover made of thick sheet 31. The return device in the axis 32, resting on the axis 33 secured to the sheet 34 fixed to the wall of the pocket, ensures its recall in the axis in a horizontal plane.

La figure 5 est une vue schématique en élévation du dispositif de connexion selon la flèche V de la figure 1. On y voit parmi les organes solidaires du berceau 12 du- pivoteur le vérin d'accouplement pneumatique 20, son axe vertical de rotation 21A, l'un des dispositifs de rappel dans l'axe 23 de l'appareil réglant son inclinaison autour de son axe horizontal, la pièce femelle 27 d'accouplement pneumatique, l'organe 37 d'accouplement électrique et le vérin 38 de commande de l'accouplement électrique. Du côté des organes solidaires de la poche 4, la pièce mâle d'accouplement pneumatique 28, supportée par la pièce fixe 30 par l'intermédiaire de la rotule 29, voit son orientation autour de son axe horizontal réglée par un dispositif de rappel dans l'axe 35 s'appuyant sur l'axe 36 fixé sur la tôle 40. Sur cette pièce d'accouplement pneumatique est fixée la pièce d'accouplement électrique 39,. faisant face à la pièce d'accouplement 37 solidaire du- pivoteur.FIG. 5 is a diagrammatic elevation view of the connection device according to arrow V in FIG. one of the return devices in the axis 23 of the device regulating its inclination around its horizontal axis, the female part 27 of pneumatic coupling, the member 37 of electric coupling and the actuator 38 for controlling the electrical coupling. On the side of the members secured to the pocket 4, the male pneumatic coupling part 28, supported by the fixed part 30 by means of the ball joint 29, sees its orientation around its horizontal axis adjusted by a return device in the axis 35 resting on axis 36 fixed on the sheet 40. On this pneumatic coupling piece is fixed the coupling piece electric 39 ,. facing the coupling part 37 integral with the pivot.

La figure 6 représente à plus grande échelle en élévation le dispositif de connexion de la figure 5, en position de désaccouplement. On y voit plus en détail la pièce femelle 27 d'accouplement, pneumatique comprenant les deux jonctions de canalisation 47 et 48 (par exemple l'une pour de l'air, l'autre pour de l'argon), et un capteur 51 de la position de la pièce 27 au contact de la pièce 28, et destiné à commander la manoeuvre d'accouplement électrique lorsque l'accouplement pneumatique est réalisé. Au vérin de commande 20 de l'accouplement pneumatique sont associées deux tiges de guidage, dont seule l'une 45 est visible.Figure 6 shows on a larger scale in elevation the connection device of Figure 5, in the uncoupling position. We see in more detail the female coupling part 27, pneumatic comprising the two pipe junctions 47 and 48 (for example one for air, the other for argon), and a sensor 51 from the position of the part 27 in contact with the part 28, and intended to control the electrical coupling operation when the pneumatic coupling is produced. Two control rods are associated with the control cylinder 20 of the pneumatic coupling, of which only one 45 is visible.

Du côté de la poche de coulée, la pièce mâle d'accouplement pneumatique 28 comporte un cône de guidage 44 facilitant le centrage mutuel des accouplements jpneumatiques comportant les jonctions de canalisations 49 et 50, et permettant ainsi l'accouplement même avec un positionnement approximatif de la poche par rapport au pivoteur.On the side of the ladle, the male pneumatic coupling part 28 comprises a guide cone 44 facilitating the mutual centering of the pneumatic couplings comprising the pipe junctions 49 and 50, and thus allowing the coupling even with an approximate positioning of the pocket relative to the pivot.

Les organes d'accouplement électrique associés au pivoteur comprennent la pièce mobile 37 d'embrochage, masquée en position de désaccouplement par le cache 41, ce dernier s'effaçant par rotation de 90° dans la position 41A lorsque la pièce d'embrochage est poussée en position d'accouplement 37A par son vérin 38, auquel sont associées deux tiges de guidage, dont seule l'une 46 est visible. Un capteur 52 de détection de la position de la pièce 37 commande un contact électrique ne permettant le désaecouplement pneumatique que lorsque le désaccouplement électrique est déjà réalisé.The electrical coupling members associated with the pivot include the movable racking part 37, hidden in the uncoupling position by the cover 41, the latter disappearing by rotation of 90 ° in position 41A when the racking piece is pushed in the coupling position 37A by its jack 38, with which are associated two guide rods, of which only one 46 is visible. A sensor 52 for detecting the position of the part 37 controls an electrical contact allowing pneumatic uncoupling only when the electrical decoupling is already carried out.

En face de la pièce 37 d'embrochage associée au pivoteur se trouve la pièce fixe 39 associée à la poche de coulée. Cette dernière pièce est également masquée en position de désaccouplement par le cache 42, qui s'efface également par rotation de 90° lors de l'accouplement électrique.Opposite the racking part 37 associated with the pivot is the fixed part 39 associated with the ladle. This last part is also hidden in the uncoupling position by the cover 42, which also disappears by rotation of 90 ° during the electrical coupling.

La figure 7 représente le même dispositif de connexion que la figure 6, mais en position d'accouplements pneumatique et électrique. Les jonctions de canalisations 47 et 49 d'une part, 48 et 50 d'autre part, sont réalisées sous l'effet de la manoeuvre du vérin 20, qui repousse la tige 53 et les tiges de guidage 45.Figure 7 shows the same connection device as Figure 6, but in the pneumatic and electrical coupling position. The pipe junctions 47 and 49 on the one hand, 48 and 50 on the other hand, are produced under the effect of the actuation of the jack 20, which pushes back the rod 53 and the guide rods 45.

Le vérin de commande de la connexion électrique 38, solidaire de la pièce femelle 27, a amené en contact les pièces embrochables 37 et 39, les caches 41 et 42 s'étant écartés par rotation.The actuator for controlling the electrical connection 38, integral with the female part 27, brought the plug-in parts 37 and 39 into contact, the covers 41 and 42 having moved apart by rotation.

Le dispositif de connexion comprend en outre un circuit pneumatique où électrique de sécurité (non représenté) permettant de désaccoupler rapidement les jonctions pneumatiques et électriques en cas d'incident de fonctionnement de la poche.The connection device also comprises a pneumatic or electrical safety circuit (not shown) enabling the pneumatic and electrical junctions to be quickly uncoupled in the event of a pocket operating incident.

L'invention s'applique avantageusement, comme décrit en référence aux figures, au branchement automatique de circuits électriques et fluidiques entre un pivoteur et une poche de coulée de matériau liquide. Mais elle a aussi d'autres applications, notamment aux branchements entre un wagon de transport d'un matériau fondu et un poste fixe, et de manière plus générale aux branchements de circuits électriques et fluidiques en milieu dangereux ou non accessible.The invention advantageously applies, as described with reference to the figures, to the automatic connection of electrical and fluid circuits between a pivot and a ladle for pouring liquid material.
