Description

Die Erfindung betrifft eine Zugseilanlenkung für Standseilbahnen bei der das Zugseil in einer konischen Hülse gehalten ist, die über ein Kipplager mit der zu haltenden Konstruktion verbunden ist.The invention relates to a pull cable linkage for funicular railways in which the pull cable is held in a conical sleeve which is connected to the construction to be held via a tilting bearing.

Aus der GB-A-499.406 und GB-A-25.079 A. D. 1899 ist es bekannt, Seilenden in konischen Büchsen zu befestigen und die Büchsen in Kipplagern, die mit dem Fahrwerk verbunden sind, zu lagern. Auf das Problem eine feinstufige Längenänderung des Seiles zu regulieren, gehen diese Veröffentlichungen nicht ein.From GB-A-499.406 and GB-A-25.079 A. D. 1899 it is known to fasten rope ends in conical bushings and to store the bushings in tilting bearings which are connected to the running gear. These publications do not address the problem of regulating the length of the rope in fine steps.

Die WO 87/01080 verschiebt zur feinstufigen Längenänderung des Seiles eine ganze Seilumlenkstation. Diese Konstruktion ist bei Standseilbahnen gleichbedeutend mit der Verschiebung der Bergstation bzw. größerer Teile derselben.WO 87/01080 shifts an entire rope deflection station for the fine adjustment of the length of the rope. In the case of funicular railways, this construction is synonymous with the displacement of the mountain station or larger parts of it.

Es ist weiters aus der AT-B-312.680 bekannt, das Zugseil bei Standseilbahnen mittels eines Winkelhebels im Wagenbereich zu halten und mit der Bewegung des Winkelhebels bzw. dessen Vorspannung über die Zugseilspannung das jeweilige Eigengewicht des Standseilbahnwaggons zu bestimmen, um daraus die notwendige Bremsenergie ableiten zu können. Diese Konstruktion erlaubt einen geringeren Nachstellweg zur Einjustierung des Seilbahnwagens, insbesondere wenn man die unterschiedlichen Seillängungen im Winter- und Sommerbetrieb allein durch Temperaturschwankungen in Betracht zieht. Dazu kommen noch Längungen, die sich durch die Spannung des Zugseiles ergeben und die praktisch während der Lebensdauer des Seiles nicht zum Stillstand gelangen. Diese Längungen werden zum Großteil durch Seilkürzungen richtiggestellt, die einen Stillstand der Bahn für eine längere Zeit voraussetzen und dadurch unerwünscht sind. Gleichzeitig verlangt die bewegliche Einbindung auch einen erhöhten Wartungsaufwand, sodaß mit gewissen Einschränkungen in der Praxis zu rechnen ist.It is also known from AT-B-312.680 to hold the traction cable in funicular railways by means of an angle lever in the car area and to determine the respective dead weight of the funicular railway car with the movement of the angle lever or its pretensioning via the pull cable tension in order to derive the necessary braking energy therefrom to be able to. This construction allows a shorter adjustment path for the adjustment of the cable car, especially if one takes into account the different rope lengths in winter and summer operation solely due to temperature fluctuations. In addition, there are elongations that result from the tension of the traction cable and that practically do not come to a standstill during the life of the cable. Most of these elongations are corrected by shortening the rope, which requires the railway to stand still for a long time and is therefore undesirable. At the same time, the flexible integration also requires increased maintenance, so that certain restrictions can be expected in practice.

Die Erfindung hat es sich zur Aufgabe gestellt, diesen Nachteilen zu begegnen und eine stufenlos verstellbare Seilanhängung zu schaffen, die mit wenigen Handgriffen eingestellt werden kann und die gleichzeitig den räumlichen Anforderungen entspricht, sodaß beim Bau der Standseilbahn die Seileinbindung praktisch auf Schienenoberkantenniveau erfolgen kann. Ein weiterer Vorteil der Konstruktion wird darin gesehen, daß die empfindlichen Bauteile wie Federnpaket und Kipplager in einer leicht demontierbaren Hülse weitestgehend vor Schmutz geschützt angeordnet sind, sodaß die für die Verkehrssicherheit unbedingt notwendige Funktion gewährleistet ist. Darüberhinaus ist es von Vorteil, die Seilkraft direkt zu bestimmen.The invention has set itself the task of addressing these disadvantages and to provide a continuously adjustable rope hitch that can be adjusted with a few simple steps and at the same time meets the spatial requirements, so that when building the funicular, the rope integration can be done practically at the top edge of the rail. Another advantage of the design is seen in the fact that the sensitive components such as the spring assembly and tilting bearings are largely protected from dirt in an easily removable sleeve, so that the function absolutely necessary for traffic safety is guaranteed. In addition, it is advantageous to determine the rope force directly.

Die Erfindung ist dadurch gekennzeichnet, daß die Hülse als Gabel ausgebildet ist, an deren Finger ein querliegender Bolzen vorgesehen ist, der in einem stufenlos verstellbaren Gewindebolzen gelagert ist, wobei die Mutter des Gewindebolzens über das Kipplager und Federn am zu haltenden Konstruktionsteil befestigt ist. Insbesondere ist zwischen dem Kipplager und den Federn eine Hülse mit Schaltlineal für die Auslösung der Schlaffseilsicherung angeordnet, und vorzugsweise der Bolzen als Lastmeßbolzen ausgebildet.The invention is characterized in that the sleeve is designed as a fork, on the fingers of which a transverse bolt is provided, which is mounted in a continuously adjustable threaded bolt, the nut of the threaded bolt being fastened to the structural part to be held via the tilting bearing and springs. In particular, a sleeve with a switching ruler for triggering the slack rope safety device is arranged between the tilting bearing and the springs, and preferably the bolt is designed as a load measuring bolt.

Durch die Maßnahmen des Anspruches 2 und 3 wird die Sicherheit noch weiter erhöht, so daß insbesondere durch die Ausbildung des Bolzens als Lastmeßbolzen auch das Gewicht des jeweiligen Wagens bzw. dessen Zugkraft unmittelbar abgelesen werden kann.By the measures of claim 2 and 3, the security is increased even further, so that the weight of the respective carriage or its tractive force can be read directly, in particular by the design of the bolt as a load measuring bolt.

Die Erfindung ist in der angeschlossenen Figur beispielsweise und schematisch dargestellt.The invention is shown, for example and schematically, in the attached figure.

In der konischen Hülse 2 einer gabelförmig ausgebildeten Einrichtung ist das Zugseil 1 vergossen, wobei zur elektrischen Entkoppelung zwischen den beiden Bauteilen eine elektrische Isolierung vorgesehen sein kann, so daß das Zugseil auch als Übertragungsmittel für elektrische Impulse verwendbar ist. Die Hülse 2 ist zweifingrig ausgebildet, wobei ein querliegender Bolzen 4 an deren Fingern gelagert ist, der durch die Anordnung von Dehnungsmeßstreifen oder ähnlichen Einrichtungen als Lastmeßbolzen ausgebildet ist, so daß die Spannkraft des Zugseiles jederzeit ablesbar ist. Die Messung dient zum "Vorbestimmen" der Bremskraft im Falle eines Seilrisses und gehört daher zur Sicherheitsausrüstung. Etwa in der Mitte des Bolzens 4 ist ein Gewindebolzen 5 angeordnet, der an seinem anderen Ende das Gewinde trägt, und so mittels Muttern, die als Kontramuttern ausgebildet sind, stufenlos verstellbar ist. Die Muttern 6 stützen sich auf ein Kipplager 7, so daß sich der Gewindebolzen 5 frei einstellen läßt und das Gewinde keine Biegebeanspruchung aufnehmen muß. Die Hülse 2 wird dadurch in Kraftrichtung eingerichtet. Das Kipplager 7 stützt sich mit seinem anderen Ende auf Federn 8, welche letzten Endes an dem einzuhängenden Konstruktionsteil 9 wie z.B. Fahrgestell oder Wagenrahmen, befestigt sind. Federn 8 und Kipplager 7 sind durch eine zylindrische Hülse 10 abgedeckt, so daß weder Schmutz oder andere Störelemente in die Bauteile eindringen können. An der Außenseite der Hülse 10 ist schließlich noch ein Schaltlineal 11 angeordnet, welches das Auslöseventil 12 für die nicht dargestellte Bremse wie z.B. Schienenbremse, des Wagens führt.In the conical sleeve 2 of a fork-shaped device, the traction cable 1 is cast, and electrical insulation can be provided for the electrical decoupling between the two components, so that the traction cable can also be used as a transmission means for electrical impulses. The sleeve 2 is formed with two fingers, a transverse bolt 4 being mounted on their fingers, which is designed as a load measuring bolt by the arrangement of strain gauges or similar devices, so that the tensioning force of the pulling rope can be read at any time. The measurement serves to "pre-determine" the braking force in the event of a rope break and is therefore part of the safety equipment. Approximately in the middle of the bolt 4, a threaded bolt 5 is arranged, which carries the thread at its other end, and is thus infinitely adjustable by means of nuts, which are designed as counter nuts. The nuts 6 are supported on a tilting bearing 7, so that the threaded bolt 5 can be freely adjusted and the thread does not have to absorb any bending stress. The sleeve 2 is thereby set up in the direction of the force. The tilting bearing 7 is supported with its other end on springs 8, which are ultimately fastened to the structural part 9 to be hooked in, such as, for example, the chassis or carriage frame. Springs 8 and tilt bearing 7 are covered by a cylindrical sleeve 10, so that neither dirt or other interference elements can penetrate into the components. Finally, on the outside of the sleeve 10 there is also a switching ruler 11, which guides the release valve 12 for the brake (not shown) of the carriage, such as a rail brake.

Die besonderen Vorteile der beschriebenen Einrichtung sind durch den einfachen Aufbau, den Montageaufwand, die Wartungsfreundlichkeit, die räumliche Selbstzentrierung und die einfache zuverlässige Schlappseilauslösung sowie vor allem durch die Möglichkeit der direkten richtungsfreien Seilzugmessung mit Hilfe einer elektronischen Schaltung sowie durch die einfache Verschiebbarkeit des exakten Wagenanhängepunktes durch Verstellung einer Mutter 6 gegeben. Dies bringt, wie bereits angegeben, den Vorteil, daß Reckungen des Seiles auf Grund von Alterung über einen gewissen Zeitraum durch einfaches Nachstellen des Anhängepunktes ausgeglichen werden können, womit der Zeitraum zwischen den zeitaufwendigen Seilkürzungsarbeiten verlängert werden kann. Der Bolzen 4 ist durch Anordnung von nicht dargestellten Dehnungsmeßstreifen als Lastmeßbolzenmeßeinrichtung ausgebildet, so daß der Seilzug direkt und richtungsfrei gemessen werden kann. Dadurch ergibt sich eine weitere Besonderheit der erfindungsgemäßen Vorrichtung, so daß auch die benötigte Bremskraft und auch die Bremsauslösung im Falle von Schlaffseil vorbestimmt werden kann. Als Federn 8 werden z.B. Tellerfedern verwendet, die auf kleinstem Raum arbeiten und als bewährter Bauteil die Funktionssicherheit positiv beeinflußen. Darüber hinaus läßt sich auch durch geeignete Ausbildung der Hülse 10 als Hydraulikeinrichtung, insbesondere in Ersetzung des Federnpaketes, die Funktionstüchtigkeit der Anlage überprüfen. Die sinnvolle Form des Gehäuses bzw. der Hülse 10 vermeidet eine Überlastung der Auslösefeder, wodurch auch eine obere Begrenzung der Auslösekraft bzw. der Gehäusebewegung gegeben ist. Eine Führungsplatte überdeckt zuletzt das Gehäuse und stützt es zum Wagenaufbau hin ab. Demontierbare Abdeckungen unter der gesamten Aufhängevorrichtung sorgen für einen zusätzlichen Schutz von unten, so daß die empfindlichen Teile der Verstelleinrichtung witterungsgeschützt angeordnet sind.The special advantages of the described device are the simple structure, the assembly effort, the ease of maintenance, the spatial self-centering and the simple, reliable slack rope release as well as, above all, the possibility of direct, direction-free cable pull measurement with the help of an electronic circuit, as well as the easy displacement of the exact vehicle attachment point Adjustment of a mother 6 given. As already stated, this has the advantage that stretching of the rope due to aging can be compensated for over a certain period of time by simply adjusting the attachment point, which means that the period between the time-consuming rope shortening work can be extended. The bolt 4 is formed by the arrangement of strain gauges, not shown, as a load measuring device, so that the cable can be measured directly and without direction. This results in a further peculiarity of the device according to the invention, so that the required braking force and also the brake release in the case of slack rope can be predetermined. As springs 8, for example, disc springs are used, which work in the smallest space and, as a proven component, have a positive effect on the functional reliability. In addition, the functionality of the system can also be checked by suitably designing the sleeve 10 as a hydraulic device, in particular by replacing the spring assembly. The sensible shape of the housing or the sleeve 10 avoids overloading the release spring, which also results in an upper limitation of the release force or the housing movement. Finally, a guide plate covers the housing and supports it towards the car body. Removable covers under the entire suspension device provide additional protection from below, so that the sensitive parts of the adjustment device are arranged protected from the weather.
