Abstract

A damper is described for cableway traction cables comprising a carrying cable (2) stretched between a downstream station and an upstream station with a traction cable (3) returned by pulleys in the stations and at least one support (9) of the cables (2, 3) provided along the path of the cableway and bearing a support and a roller battery and a plurality of cabins (4) running along the carrying cables (2) and can be coupled with the traction cable (3) by means of clamps (6). In accordance with this invention to the structure of the roller battery and preferably at the entrance of the roller battery in the direction of movement (16) of the cabins there is joined a lever (12) bearing at its free end a roller (13) engaged on the traction cable (3) and the lever is loaded by elastic means or weights towards the traction cable in such a manner as to soften the passage of this roller over the back of the clamp and to accompany the traction cable in the lowering onto the roller battery.

Description

Die vorliegende Erfindung bezieht sich auf eine Dämpfungsvorrichtung für Zugseile von Seilbahnen gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a damping device for ropes of cable cars according to the preamble of claim 1.

Seilbahnen dieser Art umfassen ein zwischen einer Talund einer Bergstation gespanntes Tragseil und ein Zugseil, das sich in den entsprechenden Stationen durch jeweils eine Scheibe umgelenkt kontinuierlich bewegt wird, von denen eine eine Antreibscheibe ist. Auf dem Tragseil laufen die Fahrwerke der Kabinen, die an den Fahrwerken selbst über eine Aufhängung angehängt sind, die mit dem Zugseil über eine Klemme kuppelbar sind. Die Klemme selbst weist in diesem Fall einen Klemmrücken auf einer der Backen auf, der vom Zugseil nach unten ragt.Ropeways of this type comprise a tensioning cable stretched between a valley and a mountain station and a traction cable which is continuously moved in the respective stations through a disk in each case, one of which is an antreibscheibe. On the suspension cable run the chassis of the cabins, which are attached to the chassis itself via a suspension, which can be coupled with the pull rope via a clamp. The clamp itself has in this case a clamping back on one of the jaws, which protrudes from the pull rope down.

Im Fall wo zwischen der Tal- und Bergstation Stützen vorhanden sind, die das Tragseil in seinem Verlauf über einen Träger und das Zugseil über eine Rollenbatterie abstützen, besteht das Problem, dass die Klemme beim Durchlauf des Fahrwerkes das Zugseil anheben muss, um nicht mit der Rollenbatterie in Berührung zu kommen. Gleich nach dem Durchlaufen des Fahrzeugs legt sich das Zugseil von Neuem auf die Rollenbatterie der Stütze und der Aufprall erzeugt eine Welle bzw. eine Schlagbewegung im Zugseil, die sich längs der Linie ausbreitet, wobei sie zurückgeworfen wird, und die Amplitude bei der Annäherung des Fahrzeuges vor allem wenn sich die Wellenberge der fortgepflanzten und jener zurückgeworfenen Wellen überlagern. Es ist leicht vorstellbar, dass diese Wellen Flatterbewegungen erzeugen und, außer für die Passagiere unangenehm zu sein, eine unlässige Bewegung des Zugseils hervorrufen könnten.In the case where there are supports between the valley and top station, which support the support cable in its course via a support and the pull rope via a roller battery, there is the problem that the clamp must lift the pull rope during passage of the landing gear, so as not to Roller battery to come into contact. Immediately after passing through the vehicle, the traction cable again lays on the roller battery of the support and the impact generates a wave in the traction cable, which propagates along the line, being thrown back, and the amplitude at the approach of the vehicle especially when the waves overlap the propagated and the reflected waves. It is easy to imagine that these waves are fluttering and, except for being uncomfortable for the passengers, could cause unrelenting movement of the tow rope.

Aus der Veröffentlichung FR-A-2 670 452 ist eine Dämpfungsvorrichtung für Zugseile, umfassend ein Tragseil, das zwischen einer Tal- und einer Bergstation gespannt ist, ein durch Scheiben in Stationen umgelenktes Zugseil, mindestens eine Stütze der Seile, die längs des Verlaufs der Umlaufbahn vorgesehen ist und einen Träger und eine Rollenbatterie trägt, und eine Vielzahl von längs der Tragseile laufenden Kabinen, die am Tragseil über Klemmen kuppelbar sind, wobei am Aufbau der Rollenbatterie bevorzugter Weise am Eingang der Rollenbatterie in Bewegungsrichtung der Kabine ein Hebel angelenkt ist, der an seinem freien Ende ein am Zugseil angreifendes Röllchen trägt, und wobei der Hebel selbst durch Federmittel in Richtung des Zugseils derart belastet ist, so dass das Passieren dieses Röllchens am Rücken der Klemme sanft gestaltet wir und das Zugseil beim Absenken auf die Rollenbatterie begeleitet wird.From the publication FR-A-2 670 452 is a damper device for traction ropes, comprising a carrying rope, which is stretched between a valley and a mountain station, a deflected by discs in stations traction cable, at least one support of the cables, along the course of the Orbital path is provided and carries a carrier and a roller battery, and a plurality of along the support cables running cabins, which are coupled to the support cable via terminals, wherein the structure of the roller battery preferred manner at the entrance of the roller battery in the direction of movement of the cabin, a lever is hinged at its free end carries a pulling rope acting on the rope, and wherein the lever itself is loaded by spring means in the direction of the hawser so that the passing of this Röllchens gently at the back of the clamp we designed and the pull rope is guided when lowering the roller battery.

Aus diesem Dokument ist überdies eine Dämpfungsvorrichtung für Zugseile von Seilbahnen bekannt, bei der der Hebel durch einen Stossdämpfer gedämpft wird.From this document, moreover, a damping device for ropes of cable cars is known in which the lever is damped by a shock absorber.

Die Aufgabe der vorliegenden Erfindung ist daher das Problem der Wellenerzeugung zu unterdrücken oder zumindest zu reduzieren, indem die Schlag- und Flatterbewegungen in einem Höchstmaß vermieden werden, indem eine Dämmungs- und Stoßauffangvorrichtung geschaffen wird, die die Ursache der Wellenbildung in einem Höchstmaß eingrenzt.The object of the present invention is therefore to suppress or at least reduce the problem of wave generation by maximally avoiding the flapping and flapping motions by providing an insulation and shock absorbing device which maximizes the cause of the wave formation.

Diese Aufgabe wird erfindungsgemäß im kennzeichnenden Teil des Anspruchs 1 gelöst.This object is achieved in the characterizing part of claim 1.

Wird am Eingang der Rollenbatterie ein Hebel angelenkt, der an seinem anderen Ende eine am Zugseil angreifende Rolle trägt und wird der Hebel selbst über Federmittel oder Gewichte in Richtung des Zugseils belastet, so legt sich der Klemmrücken oder auch die Auflaufzunge der Klemme, soweit vorhanden, weicher auf diese abgedämpfte Rolle der Rollenbatterie. Die Belastung dieses Hebels wird derart gewählt, dass der Durchlauf auf dieser Rolle auf dem Klemmrücken sanft gestaltet wird wobei der Hebel durch eine Feder belastet und durch einen Stoßdämpfer gedämpft wird und der Stoßdämpfer einstellbar und pneumatischer oder hydraulischer Art ist.If at the entrance of the roller battery a lever is articulated, which carries at its other end a tensioning rope acting on the rope and the lever itself is loaded by spring means or weights in the direction of the pull rope, so puts the clamping back or the tongue of the clamp, if any, softer on this damped roll of the roller battery. The load of this lever is chosen such that the passage on this roller on the clamping back is made gentle, wherein the lever is loaded by a spring and damped by a shock absorber and the shock absorber is adjustable and pneumatic or hydraulic type.

In einem weiteren Ausführungsbeispiel ist dem einer Rolle angelenkte Hebel, bevorzugter Weise vor der ersten Rolle der Rollenbatterie ein zweiarmiger Hebel zugeordnet, von dem einer der Arme im Bereich seines ersten freien Endes an einem Stützaufbau angelenkt und durch eine Druckfeder gegenüber der Rollenbatterie abgestützt, während der andere Arm an seinem freien Ende eine Führung trägt, die auf dem Tragseil läuft, wobei im Hebelknie des zweiarmigen Hebels ein Widerstandsmittel vorgesehen ist, das auf dem an der ersten Rolle angelenkten Hebel läuft, wobei der Hebel mit einem optimalen Abstand niedergedrückt wird, um der Klemme zu erlauben, oberhalb dieser Rolle ohne Überschneidung durchzulaufen.In a further embodiment, the lever hinged to a roller, preferably associated with a two-armed lever in front of the first roller of the roller battery, of one of the arms articulated in the region of its first free end to a support structure and supported by a compression spring against the roller battery, while the other arm carries at its free end a guide which runs on the support cable, wherein provided in the lever knee of the two-armed lever resistance means which is running on the lever hinged to the first roller, the lever being depressed with an optimum distance to allow the clamp to pass above this roller without overlapping.

In einer Variante ist die Führung des zweiten Arms durch eine Kehlröllchen gebildet.In a variant, the guide of the second arm is formed by a Kehlröllchen.

Bevorzugter Weise ist das Widerstandsmittel ein Zapfen oder ein Rädchen.Preferably, the resistance means is a pin or a wheel.
