Abstract

The pulley assembly consists of a chassis (6) in the form of a 'U' having two support brackets (4,5). The pulley (1) has an hydraulic motor (2,3) fitted to each flange. The hydraulic motors ensure that the pulley assembly is self driving with speed adjustment, at the same time incorporating the pulley bearings.

Description

La présente invention concerne une poulie sur laquelle sont flasqués de part et d'autre des moteurs spéciaux à commande hydrostatique. Ce dispositif permet l'entraînement d'un câble de télésiège, de téléphérique ou tout autre appareil similaire. The present invention relates to a pulley on which are flanged on either side special motors with hydrostatic control. This device allows the cable of a chairlift, cable car or any other similar device to be driven.

Dans les systèmes connus de ce genre, la poulie motrice est généralement calée sur l'arbre lent d'un groupe moto-réducteur à engrenages. In known systems of this kind, the driving pulley is generally wedged on the slow shaft of a geared motor group.

Les chaînes cinématiques ainsi conçues posent des problèmes de variation de vitesse qui impliquent l'utilisation d'appareillages électriques spéciaux.The kinematic chains thus designed pose problems of speed variation which imply the use of special electrical equipment.

D'autre part, la fiabilité des composants mécaniques est incertaine du fait des conditions quelquefois très rudes.On the other hand, the reliability of the mechanical components is uncertain due to the sometimes very harsh conditions.

L'objet de l'invention permet d'éviter ces inconvénients, tout en apportant une meilleure souplesse de fonctionnement. En effet, la jante extérieure entraînant le câble porteur tracteur est solidaire de deux moteurs hydrauliques montés en opposition, qui outre leur fonction motrice en rotation constituent également les paliers. Cet ensemble peut alors être posé sur un lorry classique permettant la réalisation d'une station dite "motrice" d'une extrême simplicité. Le mouvement de rotation est assuré pour les marches normale et de secours par des pompes hydrauliques respectivement solidaires d'un moteur asynchrone standard et d'un moteur thermique. The object of the invention makes it possible to avoid these drawbacks, while providing better operating flexibility. Indeed, the outer rim driving the tractor carrying cable is integral with two hydraulic motors mounted in opposition, which in addition to their rotary driving function also constitute the bearings. This assembly can then be placed on a conventional lorry allowing the realization of a so-called "motor" station of an extreme simplicity. The rotational movement is ensured for normal and emergency steps by hydraulic pumps respectively secured to a standard asynchronous motor and a heat engine.

Le dessin annexé est une vue d'ensemble sur lequel sont repérés les éléments constitutifs. The attached drawing is an overview on which the constituent elements are identified.

Tel qu'il est représenté l'ensemble comporte un chassis mécano-soudé 6 en forme de U. Sur les platines avant sont fixés les moteurs hydrauliques supérieur 2 et inférieur 3 montés en opposition par l'intermédiaire des supports 4 et 5. Entre les couronnes de sortie des moiteurs, est rendue solidaire par bdulonnage une poulie 1 comportant une jante dans laquelle vient reposer le cible 7. As shown, the assembly includes a mechanically welded chassis 6 in the shape of a U. On the front plates are fixed the upper 2 and lower 3 hydraulic motors mounted in opposition by means of the supports 4 and 5. Between the output dampers, is made integral by bdulonnage a pulley 1 comprising a rim in which rests the target 7.

Le dispositif objet de l'invention peut être utilisé dans tous les cas ou il est nécessaire d'entraîner une poulie pour câble tracteur, ou porteur tracteur et plus particulièrement dans le domaine des remontées mécaniques telles que téleskis, télésièges ou téléphériques. D'autres applications intéressantes peuvent être trouvées également dans les appareils de manutention ou de levage, tels que blondins ou autres systèmes similaires comportant une poulie à adhérence.  The device which is the subject of the invention can be used in all cases where it is necessary to drive a pulley for a tractor cable or a tractor carrier and more particularly in the field of mechanical lifts such as drag lifts, chairlifts or cable cars. Other interesting applications can also be found in handling or lifting devices, such as rams or other similar systems comprising an adhesion pulley.
