Description

La présente invention concerne le domaine de l'alimentation électrique de mécanismes mobiles tels que des ponts roulants, des monorails, des palans, des petits outils de travail du type perceuse, machine à visser, ou analogue, et d'autres dispositifs déplaçables, au moyen d'une gaine, et a pour objet un dispositif d'alimentation électrique pour de tels mécanismes.The present invention relates to the field of the electrical supply of mobile mechanisms such as overhead traveling cranes, monorails, hoists, small work tools of the drill, screwing machine or similar type, and other movable devices, to the by means of a sheath, and relates to an electrical supply device for such mechanisms.

Les dispositifs d'alimentation de ce type existant actuellement, se présentent généralement sous la forme d'un conducteur sur lequel vient frotter un capteur de courant, dont le guidage est assuré par l'enveloppe isolante du conducteur ou par un dispositif extérieur au dispositif d'alimentation.Feeding devices of this type currently existing generally take the form of a conductor on which a current sensor rubs, the guidance of which is provided by the insulating envelope of the conductor or by a device external to the device. 'food.

Cependant, ces dispositifs connus nécessitent des dispositifs annexes de guidage et assurant le maintien d'un bon contact électrique augmentant d'autant les risques de fonctionnement défectueux ou d'un manque de fiabilité.However, these known devices require additional guiding devices and ensuring the maintenance of a good electrical contact, thereby increasing the risks of faulty operation or of a lack of reliability.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un dispositif d'alimentation électrique pour mécanismes mobiles, caractérisé en ce qu'il est constitué par un conducteur en forme de caisson muni d'une enveloppe isolante, et par un preneur de courant sous forme d'un chariot-guide épousant les contours intérieurs du conducteur et pourvu d'un balai preneur de courant, qui est poussé en contact avec le conducteur au moyen de ressorts de pression, et qui est relié à la machine à alimenter correspondante par un câble de liaison souple.It relates, in fact, to an electrical supply device for mobile mechanisms, characterized in what it consists of a box-shaped conductor provided with an insulating envelope, and a current collector in the form of a guide carriage conforming to the internal contours of the conductor and provided with a current collector brush, which is pushed into contact with the conductor by means of pressure springs, and which is connected to the corresponding machine to be supplied by a flexible connection cable.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence'au dessin schématique annexé, dans lequel : la figure 1 est une vue en élévation latérale et en coupe longitudinale d'un dispositif conforme à l'invention, et la figure 2 est une vue en coupe suivant A-A de la figure 1. Conformément à l'invention, et comme le montrent plus particulièrement, à titre d'exemple, les figures 1 et 2 du dessin annexé, le dispositif d'alimentation électrique pour mécanismes mobiles est constitué par un conducteur en forme de caisson 1, qui est muni d'une enveloppe isolante 2, et par un preneur de courant sous forme d'un chariot-guide 3.The invention will be better understood thanks to the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawing, in which: FIG. 1 is a side elevational view in longitudinal section of a device according to the invention, and FIG. 2 is a sectional view along AA of FIG. 1. In accordance with the invention, and as shown more particularly, by way of example, Figures 1 and 2 of the accompanying drawing, the power supply device for mobile mechanisms is constituted by a box-shaped conductor 1, which is provided with an insulating jacket 2, and by a current taker under shaped like a guide carriage 3.

Ce dernier présente un contour épousant les contours intérieurs du conducteur 1, et est pourvu d'un balai 4 de prise de courant, qui est poussé en contact avec le conducteur 1 au moyen de ressorts de pression 5, et qui est relié à la machine à alimenter correspondante par un câble de liaison souple 6.The latter has a contour matching the interior contours of the conductor 1, and is provided with a brush 4 for an electrical outlet, which is pushed into contact with the conductor 1 by means of pressure springs 5, and which is connected to the machine to be supplied correspondingly by a flexible connection cable 6.

Sur au moins une de ses surfaces en contact avec le conducteur 1, le chariot-guide 3 est avantageusement muni d'une couche de revêtement 7 en un matériau anti-friction, de préférence sur ses faces inférieures latérales supportant la plus grande charge et la force de réaction des ressorts 5.On at least one of its surfaces in contact with the conductor 1, the guide carriage 3 is advantageously provided with a coating layer 7 made of an anti-friction material, preferably on its lateral undersides supporting the greatest load and the spring reaction force 5.

Ainsi, un guidage parfait du chariot-guide 3 dans le conducteur 1 est assuré de manière parfaite, tout en évitant une usure indésirable des surfaces en contact.Thus, perfect guidance of the guide carriage 3 in the conductor 1 is ensured in a perfect manner, while avoiding undesirable wear of the surfaces in contact.

Le conducteur en forme de caisson 1 est une gaine d'alimentation dont les solutions de continuité reprennent les caractéristiques de FR - A - 2 420 864, notamment pour la prise en compte des phénomènes de dilatation.The box-shaped conductor 1 is a supply sheath whose continuity solutions take up the characteristics of FR - A - 2 420 864, in particular for taking into account expansion phenomena.

Les suspensions destinées à la fixation des conducteurs et de leur enveloppe peuvent être montées par encliquetage dans le conducteur 1 suivant une disposition modulaire à entraxe constant.The suspensions intended for fixing the conductors and their casing can be snap-fitted into the conductor 1 in a modular arrangement with constant center distance.

Grâce à l'invention, il est possible d'assurer le guidage d'un capteur de courant, tel que le chariot-guide 3, en totalité par le conducteur 1, sans aucun organe annexe, les forces nécessaires au maintien d'un bon contact électrique étant intérieures à l'ensemble conducteur 1 - chariot-guide 3. En effet, la force d'application du balai preneur de courant 4 contre la face correspondante du conducteur 1, fournie par les ressorts 5, engendre une force de réaction tendant à appliquer les surfaces de guidage du chariot-guide 3 contre les surfaces correspondantes dudit conducteur 1.Thanks to the invention, it is possible to guide a current sensor, such as the guide carriage 3, entirely by the conductor 1, without any additional member, the forces necessary to maintain a good electrical contact being internal to the conductor 1 - guide carriage 3 assembly. Indeed, the force of application of the current pickup brush 4 against the corresponding face of the conductor 1, supplied by the springs 5, generates a tending reaction force applying the guide surfaces of the guide carriage 3 against the corresponding surfaces of said conductor 1.

Enfin, le conducteur 1 assure lui-même sa fonction de transport de courant et de support mécanique, l'enveloppe 2 assurant uniquement une fonction d'isolation électrique.Finally, the conductor 1 itself performs its current transport and mechanical support function, the casing 2 providing only an electrical insulation function.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
