Abstract
Description
L'invention concerne un dispositif articulé d'entrainement en rotation d'une pièce, tel un boisseau de vanne, autour de son axe, d'une valeur angulaire bien déterminée, à partir d'un moyen à déplacement linéaire, tel un vérin. The invention relates to an articulated device for driving a part in rotation, such as a valve plug, around its axis, with a well-determined angular value, using a linear displacement means, such as a jack.
Les dispositifs connus permettent de mettre en rotation, par exemple un boisseau de vanne, sont du type moto-réducteur et nécessitent des détecteurs de position pour déterminer la valeur angulaire de rotation, donc un automatisme. En outre, certains blocages peuvent provoquer la mise hors service des moto-réducteurs s'ils ne sont pas équipés de dispositifs de sécurité. The known devices make it possible to rotate, for example a valve plug, are of the geared motor type and require position detectors to determine the angular value of rotation, therefore an automation. In addition, certain blockages can cause the gearmotors to be put out of service if they are not fitted with safety devices.
La présente invention a notamment pour but de remédier à ces divers inconvénients en supprimant l'utilisation de moto-réducteurs, d'automatismes et de dispositifs de sécurité. Elle concerne, à cet effet, un dispositif articulé d'entrainement en rotation d'une pièce, tel un boisseau de vanne, autour de son axe, d'une valeur angulaire bien déterminée, à partir d'un premier moyen à déplacement linéaire, tel un vérin, caractérisé en ce qu'il comporte a) deux leviers reliés : - pour l'une des extrémités du premier levier,solidairement à l'axe dtentraînement de la pièce rotative, - pour l'une des extrémités du deuxième levier, à un point d'articulation solidaire d'un support du châssis de l'ensemble; b) une bielette reliant les extrémités libres desdits leviers par l'intermédiaire de points d'articulation; c) un moyen, à déplacement linéaire, dont l'extrémité de la tigepiston vient actionner le deuxième levier en un point d'articulation situé sur ledit levier, et dont le corps est solidaire dudit support par l'intermédiaire d'un point d'articulation, de telle manière que le déplacement dudit piston provoque la rotation de l'axe d'entrainement par l'intermédiaire des deux leviers et de la bielette, avec effet multiplicateur. The object of the present invention is in particular to remedy these various drawbacks by eliminating the use of geared motors, automatisms and safety devices. To this end, it relates to an articulated device for driving a part in rotation, such as a valve plug, around its axis, with a well-determined angular value, from a first means with linear displacement, such as a jack, characterized in that it comprises a) two levers connected: - for one of the ends of the first lever, integral with the axis of drive of the rotary part, - for one of the ends of the second lever, at a point of articulation secured to a support of the chassis of the assembly; b) a connecting rod connecting the free ends of said levers by means of articulation points; c) a means, with linear displacement, the end of the tigepiston of which actuates the second lever at a point of articulation situated on said lever, and the body of which is secured to said support by means of a point of articulation, in such a way that the displacement of said piston causes the rotation of the drive axis via the two levers and the link, with multiplier effect.
Selon une autre caractéristique de l'invention, le support, qui est en fait libre en rotation par rapport au chassies, dans la zone de l'axe d'entraînement, est entraîné en rotation par un deuxième moyen à déplacement linéaire, dont l'extrémité de la tige-piston est reliée audit support par l'intermédiaire d'un point d'articulation, et dont le corps est solidaire du châssis de l'ensemble par l'intermédiaire d'un point d'articulation, de telle manière que le déplacement angulaire dudit support vienne s'ajouter au déplacement angulaire de l'axe d'entrainement provoqué par le premier moyen de déplacement linéaire et de l'ensemble articulé correspondant. According to another characteristic of the invention, the support, which is in fact free to rotate relative to the casings, in the region of the drive axis, is driven in rotation by a second means with linear displacement, the end of the piston rod is connected to said support by means of a hinge point, and the body of which is secured to the frame of the assembly by means of a hinge point, so that the angular displacement of said support is added to the angular displacement of the drive axis caused by the first linear displacement means and of the corresponding articulated assembly.

Pour des raisons de commodités, le rotor n'a pas été représenté sur les figures. For reasons of convenience, the rotor has not been shown in the figures.
Le fonctionnement de l'ensemble est le suivant - Position initiale : le verin (12) est en position de repos, le support (3) est dans la position (al), le levier (7) est dans la position (b l ), le levier (5), solidaire de l'axe (4),est dans la position (cl) ( figure 1 ); - Dans la position intermédiaire : le vérin (12) est en position de travail alors que le vérin (13),solidaire du support (3),est en position de repos, le support (3) est dans la position (a),le levier (7) est dans la position (b), le levier (5) est dans la position (c) : l'angle formé par les axes (cl) et (c) détermine la rotation de l'axe (4), exemple : 900 dans la réalisation préférée de l'invention, - Dans la position finale : le vérin (13) est en position de travail, ainsi que le vérin (12) qui n'a pas changé d'état, le support (3) est toujours dans la position (a), le levier (7) est dans la position (b2), le levier (5) est dans la position (c2) : l'angle formé par les axes (c) et (c2) détermine la rotation additionnelle de l'axe (4), exemple : 1359 dans la réalisation préférée de l'invention soit au total 2250. The operation of the assembly is as follows - Initial position: the actuator (12) is in the rest position, the support (3) is in the position (al), the lever (7) is in the position (bl), the lever (5), integral with the axis (4), is in the position (cl) (Figure 1); - In the intermediate position: the jack (12) is in the working position while the jack (13), secured to the support (3), is in the rest position, the support (3) is in the position (a), the lever (7) is in position (b), the lever (5) is in position (c): the angle formed by the axes (cl) and (c) determines the rotation of the axis (4) , example: 900 in the preferred embodiment of the invention, - In the final position: the jack (13) is in the working position, as well as the jack (12) which has not changed state, the support ( 3) is still in position (a), the lever (7) is in position (b2), the lever (5) is in position (c2): the angle formed by the axes (c) and (c2 ) determines the additional rotation of the axis (4), example: 1359 in the preferred embodiment of the invention, ie a total of 2250.
Ainsi, la combinaison de deux déplacements linéaires provoque un déplacement angulaire de grande amplitude;
Les points d'articulation (11) et (14), les courses des vérins (12) et (13), les dimensions du dispositif articulé ( 5-6-7 ), déterminent le déplacement angulaire souhaité.Thus, the combination of two linear displacements causes an angular displacement of large amplitude;
The articulation points (11) and (14), the strokes of the jacks (12) and (13), the dimensions of the articulated device (5-6-7), determine the desired angular displacement.
I1 est définit à la fabrication ou peut être réglé en cours d'utilisation. It is defined during manufacture or can be adjusted during use.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et présenté, pour lequel on pourra prévoir d'autres variantes sans pour cela sortir du cadre de l'invention. Of course, the invention is not limited to the embodiment described and presented, for which we can provide other variants without departing from the scope of the invention.
