Abstract

A disengageable chairlift or cable car possesses, at the exit from the station, an engagement section (11) equipped with a template (25) for controlling the insertion of the cable (10) between the jaws of the gripper (16). The template (25), in the form of a sleeve with an inner contour equivalent, apart from the play, to the outer contour of the gripper and of the cable introduced into the gripper, is mounted slidably to a limited extent by means of slideways in order to damp the impact when a gripper located next to the cable is clamped and thereby reduce the rocking of the chair. <IMAGE>

Description

L'invention est relative à une installation de transport à câble aérien porteur-tracteur s'étendant entre deux stations d'extrémités, comprenant des pinces avec une paire de mors, susceptibles d'enserrer le câble pour accoupler la pince au câble en ligne et d'être ouverts pour désaccoupler la pince du câble dans les stations, des sièges ou cabines, chacun suspendu à une pince, un rail de transfert, qui s'étend dans la station pour prendre en charge la pince désaccouplée du câble, une section d'embrayage où le rail est parallèle au câble et est agencé pour introduire à l'entrée de la section le câble entre les mors de la pince et accoupler la pince par fermeture des mors au câble à la sortie de la section et un dispositif de sécurité, disposé sur la section d'embrayage, pour détecter un fonctionnement défectueux.The invention relates to an overhead cable-to-tractor transport installation extending between two end stations, comprising clamps with a pair of jaws, capable of gripping the cable to couple the clamp to the cable in line and to be open to uncouple the cable clamp in stations, seats or cabins, each suspended on a clamp, a transfer rail, which extends in the station to support the uncoupled cable clamp, a section d clutch where the rail is parallel to the cable and is arranged to introduce the cable between the jaws of the clamp at the entry to the section and couple the clamp by closing the jaws to the cable at the exit of the section and a safety device , located on the clutch section, to detect faulty operation.

Dans une installation du genre mentionné, le dispositif de sécurité déclenche l'arrêt de l'installation, lors d'un incident, afin d'éviter la sortie du siège de la station et/ou son accouplement au câble. L'arrêt n'est pas instantané et il faut donc prévoir une distance de sécurité qui contribue à l'allongement de la station.Une situation particulièrement dangereuse résulte d'une fermeture de la pince, le câble étant en dehors des mors, notamment à côté de ceux-ci.La chute du siège ou de la cabine est alors inévitable, lorsque la pince quitte le rail de transfert et des mesures de sécurité s'avèrent indispensables..In an installation of the type mentioned, the safety device triggers the stopping of the installation, in the event of an incident, in order to avoid leaving the station's seat and / or coupling it to the cable. The stop is not instantaneous and it is therefore necessary to provide a safety distance which contributes to the elongation of the station. A particularly dangerous situation results from a closing of the clamp, the cable being outside the jaws, in particular at side of them. The fall of the seat or cabin is then inevitable, when the clamp leaves the transfer rail and safety measures are essential.

La présente invention a pour but d'améliorer la sécurité de fonctionnement d'une telle installation en faisant appel à des moyens simples.The object of the present invention is to improve the operational safety of such an installation by using simple means.

L'installation selon l'invention est caractérisée en ce que ledit dispositif,de sécurité comporte un gabarit, dont la section de passage correspond, au jeu près, à la section externe de la pince et du câble introduit entre les mors de la pince, de façon à autoriser le libre passage de la pince vers la sortie de la section d'embrayage, lorsque le câble est correctement inséré entre les mors et de provoquer le coincement de la pince dans le gabarit, lorsque le câble est à l'extérieur des mors, pour empêcher la progression de la pince jusqu'à la sortie de la section .The installation according to the invention is characterized in that said safety device comprises a template, the passage section of which corresponds, apart from play, to the external section of the clamp and of the cable introduced between the jaws of the clamp, so as to allow free passage of the clamp towards the exit of the clutch section, when the cable is correctly inserted between the jaws and causing the clamp to jam in the template, when the cable is outside the jaws, to prevent the clamp from advancing up to 'at the exit of the section.

Lors d'un coincement de la pince dans le gabarit, celle-ci est stoppée brutalement et un balancement vers l'avant du siège ou de la cabine, dont la suspente est articulée sur un axe transversal de la pince, est inévitable. Afin d'éviter des incidents ce balancement ne doit pas être excessif et selon la présente invention le gabarit est monté à coulissement limité dans la direction de défilement du câble pour accompagner, lors d'un blocage, la pince dans sa course sur une distance limitée.Ce coulissement est freiné par tout moyen approprié afin de décélérer progressivement la pince.et de réduire ainsi le balancement du siège.Le gabarit en forme de cadre fermé présente une base sensiblement horizontale ou légèrement concave pour constituer un rattrapeur du câble lors d'une chute ou d'un abaissement de celui-ci, par exemple dû à une défaillance d'un galet de support.When the clamp is jammed in the template, it is suddenly stopped and a forward rocking of the seat or cabin, whose hanger is articulated on a transverse axis of the clamp, is inevitable. In order to avoid incidents, this swinging must not be excessive and according to the present invention the template is mounted with limited sliding in the direction of travel of the cable to accompany, during a blocking, the clamp in its race over a limited distance. This sliding is braked by any appropriate means in order to progressively decelerate the clamp. falling or lowering, for example due to a failure of a support roller.

Le gabarit est avantageusement monté sur des glissières, qui s'étendent parallèlement au câble,et les moyens de freinage sont incorporés ou associés à ces glissières. Lors du blocage mécanique d'une pince le câble reste en mouvement et il coulisse de force dans le gabarit en risquant de tout arracher si le mouvement persiste un certain temps. Le blocage de la pince dans le gabarit est perçu par les systèmes de sécurité usuels, qui commandent l'arrêt de l' installation,notamment par le détecteur d'oscillations excessives du câble, dues au choc ou par le contrôleur de cheminement des sièges ou cabines, appelés sièges par la suite. Des sécurités additionnelles peuvent être prévues afin de réagir, par exemple lors d'un déplacement intempestif du gabarit et d'arrêter le moteur d'entraînement, avec un temps de réponse inférieur.The template is advantageously mounted on slides, which extend parallel to the cable, and the braking means are incorporated or associated with these slides. During the mechanical blocking of a clamp the cable remains in movement and it slides forcibly in the template, risking tearing everything out if the movement persists for a certain time. The clamping of the clamp in the template is perceived by the usual safety systems, which control the stopping of the installation, in particular by the detector of excessive oscillations of the cable, due to shock or by the seat tracking controller or cabins, later called seats. Additional safety devices can be provided in order to react, for example during an untimely movement of the template and to stop the drive motor, with a lower response time.

Sur les figures un câble porteur-tracteur 10 d'une installation de transport, notamment d'une télécabine ou d' un télésiège, s'étend en boucle fermée entre deux stations, en passant à la sortie de la station par une section d' embrayage 11 où le siège 12, qui circule dans la station en roulant sur un rail 13, est réaccouplé au câble 10. Le siège 12 est porté par une suspente 14, dont l'extrémité supérieure 15 est articulée sur le corps d'une pince 16, équipée d'une paire de mors 17, susceptibles d'enserrer le câble 10, et de galets 18 de roulement sur le rail 13. Un levier 19 commande l'ouverture et la fermeture de la pince 16 et un ressort 20 sollicite les mors 17 en position de serrage du câble 10. Dans les stations la pince 16 est désaccouplée et elle roule à faible vitesse sur le rail 13 de transfert en étant entraînée par des roues de friction 21,échelonnées le long du rail 13 et qui engagent une traverse 22 solidaire de la pince 16. Le câble 10 est supporté et guidé dans la section d'embrayage 11 par des galets de support 23, la trajectoire du câble 10 étant parallèle à celle du rail 13 avec une légère pente vers le haut, pour introduire le câble 10, qui est en-dessous et à l' extérieur des mors 17 à l'entrée de la section 11, progressivement entre ces mors 17 au cours du défilement de la pince 16 et permettre l'accouplement de la pince 16 au câble 10, à la sortie 24 de cette section 11, par fermeture des mors 17. La section d'embrayage 11 est équipée de dispositifs de sécurité usuels, non représentés, qui vérifient notamment la trajectoire du câble 10, l'intégrité de la pince 16 et le cheminement correct des sièges 12.Une telle installation est bien connue des spécialistes et il est inutile de la décrire plus en détail.In the figures, a carrier-tractor cable 10 of a transport installation, in particular of a gondola or a chairlift, extends in a closed loop between two stations, passing at the station exit by a section of clutch 11 where the seat 12, which circulates in the station while rolling on a rail 13, is re-coupled to the cable 10. The seat 12 is carried by a hanger 14, the upper end 15 of which is articulated on the body of a clamp 16, equipped with a pair of jaws 17, capable of enclosing the cable 10, and rollers 18 for rolling on the rail 13. A lever 19 controls the opening and closing of the clamp 16 and a spring 20 urges the jaw 17 in the cable clamping position 10. In the stations, the clamp 16 is uncoupled and it rolls at low speed on the transfer rail 13, being driven by friction wheels 21, staggered along the rail 13 and which engage a cross 22 secured to the clamp 16. The cable 10 is t supported and guided in the clutch section 11 by support rollers 23, the path of the cable 10 being parallel to that of the rail 13 with a slight upward slope, to introduce the cable 10, which is below and outside the jaws 17 at the entrance to section 11, progressively between these jaws 17 during the movement of the clamp 16 and allow the clamp 16 to be coupled to the cable 10, at the outlet 24 of this section 11, by closing the jaws 17. The clutch section 11 is equipped with usual safety devices, not shown, which verify in particular the path of the cable 10, the integrity of the clamp 16 and the correct routing of the seats 12. Such an installation is well known to specialists and it is unnecessary to describe it in more detail.

Entre la zone d'insertion du câble 10 dans les mors 17 et la sortie 24 de la section d'embrayage 11 est disposé, transversalement à la direction de défilement du câble 10, un gabarit 25 en forme de fourreau 26, entourant les mors 17 et le câble 10 inséré entre ces mors 17. Le gabarit 25 est monté sur des glissières 27, parallèles au rail 13, qui permettent un coulissement limité du gabarit 25 en direction de la sortie 24. Les glissières 27 sont portées par l'ossature de la station ou directement par le rail 13. Des blocs de freinage 28 sont associés à ces glissières 27 ou à toute autre partie du gabarit 25, pour freiner énergiquement ce coulissement. Le contour interne 29 du fourreau 26 épouse à faible jeu le contour externe des mors 17 et du câble 10, introduit entre ces mors 17 et l'entrée du fourreau 26, qui s'étend parallèlement au câble 10, est évasée. La base 30 du fourreau 26 forme une assise horizontale ou concave, disposée légèrement en-dessous du câble 10 et susceptible de maintenir ou de rattraper ce dernier en cas de défaillance d'un élément de support, notamment d'un galet 23.Between the cable insertion area 10 in the jaws 17 and the outlet 24 of the clutch section 11 is arranged, transverse to the direction of travel of the cable 10, a jig 25 in the form of a sheath 26, surrounding the jaws 17 and the cable 10 inserted between these jaws 17. The template 25 is mounted on slides 27, parallel to the rail 13, which allow limited sliding of the template 25 in the direction of the outlet 24. The slides 27 are carried by the framework of the station or directly by the rail 13. Braking blocks 28 are associated with these slides 27 or any other part of the template 25, to vigorously brake this sliding. The internal contour 29 of the sheath 26 conforms with low clearance to the external contour of the jaws 17 and of the cable 10, introduced between these jaws 17 and the inlet of the sheath 26, which extends parallel to the cable 10, is flared. The base 30 of the sheath 26 forms a horizontal or concave seat, disposed slightly below the cable 10 and capable of holding or catching the latter in the event of a failure of a support element, in particular of a roller 23.

En se référant plus particulièrement à la figure 2 on voit qu' en fonctionnement normal le gabarit 25 n' interfère pas avec le passage de la pince 16 sur la section d'embrayage 11, le jeu entre les mors 17 et le contour interne du fourreau 26 étant suffisant pour éviter tout frottement. Si par contre le câble 10 n' est pas entre les mors 17, mais s' est placé à l'extérieur de ceux-ci, de la manière représentée à la figure 3, il est facile de voir que la pince 16 vient se coincer dans le fourreau 26 et que sous l'effet du choc le siège 12 bascule ou balance vers l'avant. Ce choc est atténué par le coulissement du gabarit 25 dans les glissières 27 et ce coulissement est freiné par les blocs de freinage 28, afin de décélérer progressivement la pince 16 et de réduire ainsi l'amplitude du balancement du siège 12. En fin de course des glissières 27 la pince 16 est bien entendu arrêtée, tandis que le câble 10 est tracté de force dans le fourreau 26 jusqu' à l'arrêt du moteur d'entraînement de l' installation. Cet arrêt est déclenché par les systèmes de sécurité usuels, qui détectent l'oscillation excessive du câble 10, due au choc ou l'interruption du cheminement des sièges 12. Un dispositif additionnel de sécurité, non représenté, peut détecter le coulissement du gabarit 25 et provoquer l'arrêt. Après un tel arrêt il convient évidemment de vérifier le bon état de l'installation et remettre le gabarit 25 en place. Le blocage mécanique de la pince 16 empêche cette dernière de dépasser un point déterminé si le câble 10 n' est pas inséré entre les mors 17 et en tous les cas d'atteindre la sortie 24 de la section d'embrayage 11. L'effort de freinage exercé sur le gabarit 25 et la course de ce freinage sont déterminés pour limiter l'amplitude de balancement du siège 12 à une valeur acceptable et non-dangereuse pour les occupants.Referring more particularly to FIG. 2, it can be seen that in normal operation the template 25 does not interfere with the passage of the clamp 16 on the clutch section 11, the clearance between the jaws 17 and the internal contour of the sheath 26 being sufficient to avoid any friction. If, on the other hand, the cable 10 is not between the jaws 17, but is placed outside of them, as shown in FIG. 3, it is easy to see that the clamp 16 is jammed in the sheath 26 and that under the effect of the shock the seat 12 rocks or swings forward. This shock is mitigated by the sliding of the template 25 in the slides 27 and this sliding is braked by the blocks of braking 28, in order to progressively decelerate the clamp 16 and thus reduce the amplitude of the rocking of the seat 12. At the end of the runners 27 the clamp 16 is of course stopped, while the cable 10 is forcibly pulled in the sheath 26 until the installation drive motor stops. This stopping is triggered by the usual safety systems, which detect the excessive oscillation of the cable 10, due to the shock or the interruption of the path of the seats 12. An additional safety device, not shown, can detect the sliding of the template 25 and cause the shutdown. After such a stop, it is obviously necessary to check the good condition of the installation and replace the template 25 in place. The mechanical locking of the clamp 16 prevents the latter from exceeding a determined point if the cable 10 is not inserted between the jaws 17 and in any case reaching the outlet 24 of the clutch section 11. The effort braking exerted on the template 25 and the stroke of this braking are determined to limit the swinging amplitude of the seat 12 to an acceptable and non-dangerous value for the occupants.

Le fonctionnement de l'installation selon l'invention découle de l'exposé précédent et il suffit de noter qu' un tel dispositif de sécurité peut être facilement monté sur une installation existante. Le fourreau 26 empêche tout déraillement de la pince 16 et sa longueur est suffisante pour assurer en tous les cas le blocage de la pince.The operation of the installation according to the invention follows from the preceding description and it suffices to note that such a safety device can be easily mounted on an existing installation. The sheath 26 prevents any derailment of the clamp 16 and its length is sufficient to ensure in all cases the clamping of the clamp.

L'invention est bien entendu nullement limitée au mode de mise en oeuvre plus particulièrement décrit.The invention is of course in no way limited to the embodiment more particularly described.
