Description

La présente invention concerne la réalisation d'un raccordement électrique déconnectable entre deux parties d'une même installation. Cette invention trouve application dans le cas où l'une des parties à raccorder, qui est typiquement fixe mais peut présenter une certaine mobilité et qui sera appelé ci-après "ensemble mobile", effectue, pendant le fonctionnement de l'installation, des déplacements limités par rapport à l'autre, qui est typiquement fixe mais peut présenter une certaine mobilité et qui sera appelée ci-après "ensemble fixe" ou "ensemble amont". De tels déplacements sont typiquement alternatifs et seront appelés ci-après "déplacements fonctionnels". Dans ce cas la connexion électrique est établie avant chaque période de fonctionnement et elle doit être maintenue pendant cette période malgré les déplacements fonctionnels. Elle permet par exemple d'alimenter électriquement l'ensemble mobile à partir de l'ensemble fixe.The present invention relates to the production of a disconnectable electrical connection between two parts of the same installation. This invention finds application in the case where one of the parts to be connected, which is typically fixed but can have a certain mobility and which will be called hereinafter "mobile assembly", performs, during the operation of the installation, displacements limited compared to the other, which is typically fixed but may have a certain mobility and which will be called hereinafter "fixed set" or "upstream set". Such displacements are typically alternative and will be called hereinafter "functional displacements". In this case the electrical connection is established before each period of operation and it must be maintained during this period despite the functional movements. It allows for example to electrically supply the mobile assembly from the fixed assembly.

Le raccordement électrique déconnectable d'un ensemble mobile à un ensemble fixe peut être réalisé par la coopération de deux blocs de connexion complémentaires constitués l'un de fiches mâles l'autre de fiches femelles. De manière générale deux tels blocs raccordés de manière permanente à l'ensemble fixe et à l'ensemble mobile seront respectivement désignés ci-après comme étant un "bloc amont" et un "bloc aval".The disconnectable electrical connection of a mobile assembly to a fixed assembly can be achieved by the cooperation of two complementary connection blocks made up one of male plugs the other of female plugs. In general, two such blocks permanently connected to the fixed assembly and to the mobile assembly will be respectively designated below as being an "upstream block" and a "downstream block".

Un premier système de raccordement connu est employé couramment. Dans ce système le bloc aval est fixe pendant le fonctionnement de l'installation et il est raccordé à des bornes électriques de l'ensemble mobile par des conducteurs souples ou du moins déformables dont les déformations autorisent les déplacements fonctionnels. Ceci peut être résumé en énoncant que le bloc aval est raccordé par des conducteurs à déformations fonctionnelles.A first known connection system is widely used. In this system the downstream block is fixed during the operation of the installation and it is connected to the electrical terminals of the mobile assembly by flexible or at least deformable conductors whose deformations allow functional movements. This can be summarized by stating that the downstream block is connected by conductors with functional deformations.

Quant au bloc amont les deux extrémités de chacun des conducteurs qui réalisent son raccordement permanent à des bornes de l'ensemble fixe sont fixes l'une par rapport à l'autre de sorte que ces conducteurs sont, sinon rigides, du moins exempts de déformations imposées par les déplacements fonctionnels. Ceci peut être résumé en énoncant que le bloc amont est raccordé par des conducteurs sans déformations fonctionnelles.As for the upstream block, the two ends of each of the conductors which make its permanent connection to the terminals of the fixed assembly are fixed relative to one another so that these conductors are, if not rigid, at least free from deformation imposed by functional displacements. This can be summarized by stating that the upstream block is connected by conductors without functional deformations.

Dans certaines situations se rencontrant dans les industries manufacturières l'ensemble mobile doit pouvoir être déconnecté et transporté à distance entre deux périodes de fonctionnement, par exemple pour être remplacé par un ensemble équivalent neuf, ou pour être réinstallé après des opérations de maintenance telles qu'une réparation ou une rénovation. L'amplitude des déplacements nécessaires à de telles opérations de remplacement ou de maintenance est beaucoup plus grande que celle des déplacements fonctionnels.In certain situations encountered in the manufacturing industries, the mobile assembly must be able to be disconnected and transported remotely between two periods of operation, for example to be replaced by a new equivalent assembly, or to be reinstalled after maintenance operations such as repair or renovation. The amplitude of the displacements necessary for such replacement or maintenance operations is much greater than that of the functional displacements.

Ils seront appelés ci-après "extrafonctionnels".They will be called hereinafter "extra-functional".

Dans un tel cas il est usuel que le bloc aval accompagne l'ensemble mobile dans ses déplacements extrafonctionnels. Ceci évite toute intervention sur le réseau électrique de cet ensemble. Mais, si ces déplacements sont réalisés par saisie et transport de cet ensemble, les déplacements correspondants du bloc aval porté par les conducteurs souples présentent des inconvénients lorsque les opérations de transport doivent être effectuées de manière rapide. De plus, après retour et mise en place d'un ensemble mobile neuf ou rénové en vue de la reprise du fonctionnement de l'installation, la remise du bloc aval en position de coopération avec le bloc amont nécessite une intervention humaine. Cette dernière est coûteuse si ces blocs sont situés dans une zone peu accessible, si l'espace manque et/ou si les conditions régnant dans cette zone sont inhospitalières, par exemple si la température est élevée.In such a case, it is usual for the downstream block to accompany the mobile assembly in its extrafunctional movements. This avoids any intervention on the electrical network of this set. However, if these movements are carried out by gripping and transporting this assembly, the corresponding movements of the downstream block carried by the flexible conductors have drawbacks when the transport operations must be carried out quickly. In addition, after the return and installation of a new or renovated mobile assembly with a view to resuming the operation of the installation, the return of the downstream block to the position of cooperation with the upstream block requires human intervention. The latter is expensive if these blocks are located in an inaccessible area, if space is lacking and / or if the conditions prevailing in this area are inhospitable, for example if the temperature is high.

Le document (US-A-4 508 404 - FRAWLEY) décrit un deuxième système de raccordement connu. Ce dernier est prévu pour raccorder provisoirement deux vaisseaux spatiaux. L'un de ces vaisseaux peut être appelé "ensemble mobile" et l'autre "ensemble amont". Ce deuxième système connu comporte :

  • deux blocs de connexion dits ci-après bloc aval et amont et raccordés électriquement de manière permanente à l'ensemble mobile et à l'ensemble amont, respectivement, un engagement mutuel de ces deux blocs réalisant une connexion électrique mutuelle temporaire de ces deux ensembles, les conducteurs raccordant le bloc amont à l'ensemble amont étant déformables,
  • un chariot effectuant des déplacements aller et retour sur une voie de transfert portée par l'ensemble amont, ce chariot portant le bloc amont tantôt lors d'un déplacement aller pour l'amener à une position avant réalisant ladite connexion tantôt lors d'un déplacement retour pour amener ce bloc à une position arrière à distance du bloc aval,
  • et des moyens d'accrochage commandés pour accrocher le bloc amont soit au bloc aval soit au chariot.
The document (US-A-4 508 404 - FRAWLEY) describes a second known connection system. The latter is intended to temporarily connect two spacecraft. One of these vessels can be called a "moving assembly" and the other an "upstream assembly". This second known system includes:
  • two connection blocks referred to below as the downstream and upstream block and electrically connected permanently to the mobile assembly and to the upstream assembly, respectively, a mutual engagement of these two blocks providing a temporary mutual electrical connection of these two assemblies, the conductors connecting the upstream block to the upstream assembly being deformable,
  • a carriage carrying outward and return movements on a transfer path carried by the upstream assembly, this carriage carrying the upstream block sometimes during a forward movement to bring it to a position before making said connection sometimes during a movement return to bring this block to a rear position away from the downstream block,
  • and hooking means controlled to hook the upstream block either to the downstream block or to the carriage.

Ce deuxième système connu n'est pratiquement pas utilisable dans les situations précédemment mentionnées se rencontrant dans les industries manufacturières.This second known system is practically not usable in the previously mentioned situations encountered in the manufacturing industries.

La présente invention a notamment pour but de réaliser d'une manière simple un système de raccordement déconnectable mieux adapté à de telles situations.The object of the present invention is in particular to provide in a simple manner a disconnectable connection system better suited to such situations.

Selon cette invention les déplacements aller et retour du chariot et le fonctionnement des organes d'accrochage sont commandés à partir de l'ensemble amont.According to this invention, the outward and return movements of the carriage and the operation of the attachment members are controlled from the upstream assembly.

Dans une ambiance industrielle cette invention présente notamment l'avantage que, lors des opérations de déconnexion, transport et reconnexion, aucune intervention n'est à effectuer sur le réseau électrique de l'ensemble mobile.In an industrial atmosphere, this invention has the particular advantage that, during disconnection, transport and reconnection operations, no intervention is to be carried out on the electrical network of the mobile assembly.

A l'aide des figures schématiques ci-jointes, on va décrire plus particulièrement ci-après, à titre d'exemple non limitatif, comment la présente invention peut être mise en oeuvre. Lorsqu'un même élément est représenté sur plusieurs figures il y est désigné par le même signe de référence.Using the attached diagrammatic figures, a more specific description will now be given below, by way of nonlimiting example, how the present invention can be implemented. When the same element is represented in several figures, it is designated therein by the same reference sign.

La figure 1 représente une vue d'un système selon l'invention, une connexion électrique étant établie par ce système.FIG. 1 represents a view of a system according to the invention, an electrical connection being established by this system.

La figure 2 représente une vue de ce système lors d'une première phase d'une opération entreprise pour supprimer cette connexion.FIG. 2 represents a view of this system during a first phase of an operation undertaken to remove this connection.

La figure 3 représente une vue de ce sytème lorsque cette connexion a été supprimée.Figure 3 shows a view of this system when this connection has been deleted.

La figure 4 représente une vue en coupe horizontale d'une lingotière de coulée continue d'acier, cette lingotière étant susceptible de constituer l'ensemble mobile du système des figures précédentes.FIG. 4 represents a view in horizontal section of an ingot mold for continuous steel casting, this ingot mold being capable of constituting the mobile assembly of the system of the preceding figures.

Conformément aux figures 1 à 3 un système de raccordement électrique déconnectable pour ensemble mobile comporte les éléments connus suivants :

  • Un bloc de connexion GB constitué de fiches de connexion telles que FB1 et raccordé électriquement de manière permanente à un ensemble mobile EB. Ce bloc constitue un "bloc aval".
  • Un bloc de connexion GA constitué de fiches de connexion telles que FA1 et raccordé électriquement de manière permanente à un ensemble fixe EA constituant ledit ensemble amont. Ce bloc constitue un "bloc amont". Il est complémentaire du bloc aval en ce sens qu'un engagement mutuel de ces deux blocs réalise une connexion électrique mutuelle temporaire de ces deux ensembles. Les conducteurs tels que CA qui le raccordent à l'ensemble EA sont déformables et typiquement souples pour permettre des déplacements fonctionnels limités de cet ensemble mobile alors que ces deux blocs sont mutuellement engagés.
In accordance with FIGS. 1 to 3, a disconnectable electrical connection system for a mobile assembly comprises the following known elements:
  • A GB connection block made up of connection plugs such as FB1 and electrically permanently connected to a mobile assembly EB. This block constitutes a "downstream block".
  • A connection block GA made up of connection plugs such as FA1 and electrically permanently connected to a fixed assembly EA constituting said upstream assembly. This block constitutes an "upstream block". It is complementary to the downstream block in the sense that a mutual engagement of these two blocks makes a temporary mutual electrical connection of these two sets. The conductors such as CA which connect it to the EA assembly are deformable and typically flexible to allow limited functional displacements of this mobile assembly while these two blocks are mutually engaged.

Un chariot K est apte à porter le bloc amont GA pour le transférer alternativement, sur commande, entre une position avant réalisant ladite connexion et une position arrière à distance du bloc aval GB. Ce chariot est apte d'autre part à se séparer sur commande de ce bloc amont placé dans cette position avant. Par ailleurs lesdits conducteurs déformables CA raccordent ce bloc amont GA à l'ensemble fixe EA alors que, dans des systèmes connus, il raccorde le bloc aval à l'ensemble mobile.A carriage K is able to carry the upstream block GA to transfer it alternately, on command, between a front position making said connection and a rear position remote from the downstream block GB. This carriage is also capable of separating on command from this upstream block placed in this front position. Furthermore, said deformable conductors CA connect this upstream block GA to the fixed assembly EA whereas, in known systems, it connects the downstream block to the mobile assembly.

Le bloc amont GA est par exemple constitué de fiches femelles telles que FA1 raccordées par des conducteurs souples à des bornes électriques de l'ensemble fixe EA. Ces conducteurs sont rassemblés dans un câble souple CA. Ces bornes sont celles d'un groupe d'alimentation BA.The upstream block GA is for example made up of female plugs such as FA1 connected by flexible conductors to electrical terminals of the fixed assembly EA. These conductors are assembled in a flexible AC cable. These terminals are those of a BA power supply group.

Le bloc aval GB est alors constitué de fiches mâles telles que FB1. Ces fiches sont raccordées par un câble rigide CB à des organes électriques à alimenter appartenant à l'ensemble mobile EB. Les fiches d'au moins l'un des deux blocs sont montées flottantes et des guides d'insertion mutuellement complémentaires tels que 2 et 3 (voir figure 3) sont disposés de manière classique pour compenser d'éventuelles inexactitudes de positionnement. La séparation des deux blocs de connexion permet à l'ensemble mobile d'effectuer des déplacements extrafonctionnels plus amples que les déplacements fonctionnels autorisés par les câbles souples.The downstream block GB then consists of male plugs such as FB1. These plugs are connected by a rigid cable CB to electrical members to be supplied belonging to the mobile assembly EB. The plugs of at least one of the two blocks are mounted floating and mutually complementary insertion guides such as 2 and 3 (see Figure 3) are arranged in a conventional manner to compensate for any inaccuracies in positioning. The separation of the two connection blocks allows the mobile assembly to make extrafunctional displacements larger than the functional displacements authorized by the flexible cables.

Plus spécifiquement le chariot K effectue des déplacements aller et retour sur une voie de transfert fixe W (voir figure 3). Cette voie est définie par exemple par des guides creux 6 qui guident des tiges 10 fixées à ce chariot.More specifically, the carriage K performs back and forth movements on a fixed transfer path W (see FIG. 3). This path is defined for example by hollow guides 6 which guide the rods 10 fixed to this carriage.

Le chariot K porte le bloc amont GA tantôt lors d'un déplacement aller PA-PB pour l'amener à sa position avant PB tantôt lors d'un déplacement retour PB-PA pour l'amener à sa position arrière PA éloignée du bloc aval GB (voir figure 3).The carriage K carries the upstream block GA sometimes during a forward movement PA-PB to bring it to its front position PB sometimes during a return movement PB-PA to bring it to its rear position PA away from the downstream block GB (see Figure 3).

Le système comporte en outre des organes d'accrochage arrière et avant LA et LB pour que le bloc amont GA qui a été placé dans sa position avant PB lors d'un déplacement aller du chariot K pour réaliser ladite connexion reste lié lors du déplacement retour consécutif du chariot soit au bloc aval GB pour maintenir cette connexion électrique soit à ce chariot pour supprimer cette connexion ce qui réalise une déconnexion.The system further comprises rear and front hooking members LA and LB so that the upstream block GA which has been placed in its front position PB during a forward movement of the carriage K to make said connection remains linked during the return movement consecutive of the carriage either at the downstream block GB to maintain this electrical connection or to this carriage to remove this connection which achieves a disconnection.

Les déplacements fonctionnels D entraînent des déplacements alternés du bloc amont GA sur un trajet linéaire W qui est typiquement de 1 à 15 mm.The functional displacements D cause alternating displacements of the upstream block GA over a linear path W which is typically from 1 to 15 mm.

De préférence la voie de transfert W suit alors ce trajet linéaire. Cette disposition présente l'avantage suivant : lorsque les déplacements fonctionnels ont été arrêtés et ont laissé le bloc amont dans une position d'arrêt non prédéterminée, il suffit que le déplacement aller du chariot K soit suffisamment prolongé pour que le chariot atteigne ce bloc quelle que soit la position d'arrêt de ce dernier.Preferably the transfer path W then follows this linear path. This arrangement has the following advantage: when the functional displacements have been stopped and have left the upstream block in a non-predetermined stop position, it suffices that the outward displacement of the carriage K is sufficiently prolonged for the carriage to reach this block whatever whatever the stop position of the latter.

Les déplacements fonctionnels sont typiquement constitués par une translation rectiligne alternée.The functional displacements are typically constituted by an alternating rectilinear translation.

Les déplacements aller PA-PB et retour PB-PA du chariot K et le fonctionnement des organes d'accrochage LA et LB sont entraînés par des actionneurs, par exemple par des verins VK, VA, VB. Tous ces actionneurs sont commandés à partir d'un même poste de commande fixe 8 par l'intermédiaire de moyens de raccordement de commande qui pourraient conduire un courant électrique ou un élément mécanique et qui sont par exemple constitués par des tuyaux d'alimentation souples TK, TA, TB conduisant un fluide de travail.The PA-PB and PB-PA return movements of the carriage K and the operation of the attachment members LA and LB are driven by actuators, for example by actuators VK, VA, VB. All these actuators are controlled from the same fixed control station 8 by means of control connection means which could conduct an electric current or a mechanical element and which are for example constituted by flexible supply pipes TK , TA, TB driving a working fluid.

Les organes d'accrochage avant LB sont entraînés par un actionneur VB pour accrocher le bloc amont GA au bloc aval GB et pour l'en décrocher. Ils sont de préférence portés par le bloc amont. Les organes d'accrochage arrière LA sont entraînés par un actionneur VA pour accrocher le bloc amont au chariot et pour l'en décrocher. Ils sont de préférence portés par le chariot K.The front attachment members LB are driven by an actuator VB to hook the upstream block GA to the downstream block GB and to unhook it. They are preferably carried by the upstream block. The rear hooking members LA are driven by an actuator VA to hook the upstream block to the carriage and to unhook it. They are preferably carried by the carriage K.

Le déplacement fonctionnel D et la voie de transfert W guidant le chariot K sont par exemple verticaux, la position avant PB du bloc amont GA étant au-dessus de sa position arrière PA. Dans ce cas, de préférence l'ensemble fixe EA porte en outre un couvercle de protection mobile 12 et un actionneur 14 pour amener ce couvercle au-dessus du bloc amont GA et protéger ainsi ce dernier lorsqu'il est dans sa position arrière PA. Bien entendu cet actionneur écarte ce couvercle du trajet de ce bloc et du chariot K lors des déplacements du chariot. Ce couvercle de protection peut aussi être posé manuellement sur le bloc amont GA.The functional movement D and the transfer path W guiding the carriage K are for example vertical, the front position PB of the upstream block GA being above its rear position PA. In this case, preferably the fixed assembly EA further carries a movable protective cover 12 and an actuator 14 to bring this cover above the upstream block GA and thus protect the latter when it is in its rear position PA. Of course, this actuator separates this cover from the path of this block and of the carriage K during movements of the carriage. This protective cover can also be placed manually on the upstream block GA.

Les fiches de connexion telles que FA1 et FB1 sont typiquement adaptées au passage d'intensités électriques supérieures à 400A, par exemple 1000A.Connection plugs such as FA1 and FB1 are typically adapted to the passage of electrical currents greater than 400A, for example 1000A.

Le système selon l'invention trouve avantageusement application dans une installation de coulée continue verticale d'un métal tel que l'acier lorsque l'ensemble mobile EB est une lingotière oscillante. Lesdits déplacements fonctionnels D sont alors constitués par une oscillation verticale qui est imposée à cette lingotière pour éviter une adhésion du métal 16 à la paroi refroidie 18 de cette lingotière. Cette paroi refroidie provoque une solidification superficielle d'un filet de métal liquide traversant la lingotière sous l'effet de la pesanteur. Elle est refroidie par une circulation d'eau 20 entre elle et une paroi externe 22. Des déplacements extrafonctionnels plus amples de cet ensemble mobile sont liés à l'enlèvement d'une lingotière usagée et à la mise en place d'une lingotière de remplacement. La lingotière comporte des inducteurs tels que 24 et 26 constituant lesdits organes électriques à alimenter et assurant un brassage électromagnétique à l'intérieur du filet de métal 16 passant dans cette lingotière. L'ensemble fixe EA est un bâti fixe de cette installation. Des bornes électriques de cet ensemble fixe sont celles d'un groupe d'alimentation électrique BA alimentant ces inducteurs par l'intermédiaire des deux dits blocs de connexion GA et GB.The system according to the invention advantageously finds application in a vertical continuous casting installation of a metal such as steel when the mobile assembly EB is an oscillating ingot mold. Said functional displacements D are then constituted by a vertical oscillation which is imposed on this mold to avoid adhesion of the metal 16 to the cooled wall 18 of this mold. This cooled wall causes a surface solidification of a liquid metal thread passing through the mold under the effect of gravity. It is cooled by a circulation of water 20 between it and an external wall 22. Larger extrafunctional displacements of this mobile assembly are linked to the removal of a used ingot mold and to the installation of a replacement ingot mold . The ingot mold includes inductors such as 24 and 26 constituting said electrical members to be supplied and ensuring electromagnetic stirring inside the metal thread 16 passing through this ingot mold. The EA fixed assembly is a fixed frame of this installation. Electrical terminals of this fixed assembly are those of a group BA power supply supplying these inductors via the two so-called GA and GB connection blocks.

Les avantages de la présente invention apparaissent alors parce que le remplacement d'une lingotière doit être rapide et ne doit être ni ralenti ni compliqué par les opérations de deconnexion et de reconnexion électrique qui doivent accompagner ce remplacement. Par ailleurs aucune intervention ne doit être effectuée sur le réseau électrique de la lingotière.The advantages of the present invention then appear because the replacement of an ingot mold must be rapid and must not be slowed down or complicated by the electrical disconnection and reconnection operations which must accompany this replacement. In addition no intervention must be carried out on the electrical network of the ingot mold.

L'ensemble mobile pourrait cependant aussi être par exemple constitué par une partie vibrante d'un transporteur à secousses si cette partie vibrante devait porter des organes électriques de puissance tels qu'un moteur entraînant une masse excentrée pour entretenir les secousses.The mobile assembly could however also be, for example, constituted by a vibrating part of a shaker conveyor if this vibrating part had to carry electrical power members such as a motor driving an eccentric mass to maintain the shaking.

Dans de telles applications industrielles la présente invention permet de commander aisément et à distance et d'effectuer rapidement des opérations de connexion et de deconnexion électrique sur des circuits aptes à conduire des intensités importantes, tout ceci sans aucune intervention manuelle sur des organes électriques.In such industrial applications, the present invention makes it possible to easily and remotely control and quickly perform electrical connection and disconnection operations on circuits capable of driving large currents, all of this without any manual intervention on electrical members.
