Abstract
Description
Die Erfindung bezieht sich auf eine Spanneinrichtung für Förderseile von Seilbahnen und Schleppliften mit einer Messeinrichtung für die Kraft, mit der das Förderseil gespannt wird, und einer Regeleinrichtung für den Antrieb der Spanneinrichtung, wobei der Antrieb der Spanneinrichtung durch die Regeleinrichtung derart betätigt wird, dass die Grundspannkraft im Förderseil konstant gehalten wird.The invention relates to a tensioning device for conveyor ropes of cable cars and drag lifts with a measuring device for the force with which the conveyor rope is tensioned, and a control device for driving the tensioning device, the drive of the tensioning device being actuated by the control device such that the Basic tension is kept constant in the rope.
Es sind Spanneinrichtungen mit einer elektromotorisch angetriebenen Seilwinde für ein Spannseil bekannt geworden, bei denen die Messung der Kraft, mit der das Förderseil gespannt wird, durch Messung der Seilspannkraft im Spannseil erfolgt. Durch diese Anordnung der Kraftmesseinrichtung ist es bei einer Spanneinrichtung der eingangs genannten Art ebenso wie bei einer Gewichtsspanneinrichtung und bei einer hydraulischen Spanneinrichtung der bekannten Bauart nur möglich, die Grundspannkraft im Förderseil in der Spannstation, also in der Station mit beweglicher Antriebs- bzw. Umlenkscheibe, konstant zu halten.Tensioning devices with an electric motor-driven winch for a tensioning rope have become known, in which the measurement of the force with which the conveyor rope is tensioned takes place by measuring the rope tensioning force in the tensioning rope. With this arrangement of the force measuring device, it is only possible with a tensioning device of the type mentioned at the outset as well as with a weight tensioning device and with a hydraulic tensioning device of the known type, the basic tensioning force in the conveyor cable in the tensioning station, that is to say in the station with a movable drive or deflection pulley, to keep constant.
Es erscheint wünschenswert, eine Spanneinrichtung zu schaffen, die es ermöglicht, die Grundspannkraft im Förderseil in der Gegenstation der Spannstation, also in der Station mit fester Antriebs- oder Umlenkscheibe, konstant zu halten.It seems desirable to create a tensioning device that makes it possible to keep the basic tensioning force in the hoisting rope constant in the opposite station of the tensioning station, that is to say in the station with a fixed drive or deflection disk.
Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Messeinrichtung für die Spannkraft in der Gegenstation (Station mit der festen Antriebs- oder Umlenkscheibe) angeordnet ist.This object is achieved according to the invention in that the measuring device for the clamping force is arranged in the opposite station (station with the fixed drive or deflection disk).
Diese Anordnung unterscheidet sich grundsätzlich von bisher bekannten Spanneinrichtungen dadurch, dass in der Spannstation das Förderseil durch die Spanneinrichtung mit einer veränderlichen, vom Belastungszustand der Seilbahn bzw. des Schleppliftes abhängigen Spannkraft gespannt wird.This arrangement differs fundamentally from previously known tensioning devices in that, in the tensioning station, the conveyor cable is tensioned by the tensioning device with a variable tensioning force which is dependent on the loading condition of the cable car or the drag lift.
Ein Vorteil der Erfindung liegt darin, dass jene Station, in der aus Gründen der Seilbemessung (Verlauf der Seilspannkräfte, Grösse und Ort des Auftretens von grösster und kleinster Seilspannkraft) die Grundspannkraft des Förderseiles konstant gehalten werden soll, mit einer festen Antriebs- oder Umlenkscheibe ausgeführt werden kann. Dies kann beispielswiese bei Sesselbahnen mit Scheibenausstieg ein betriebliches Erfordernis, zumindest aber ein betrieblicher Vorteil, z.B. bei Sesselbahnen mit Scheibeneinstieg, sein. Ebenso können konstruktive oder topographische Gegebenheiten, beispielsweise eine für eine Spannstation im Hinblick auf den erforderlichen Spannweg zu geringe Grösse eines Stationsstandortes, die Anwendung der erfindungsgemässen Spanneinrichtung vorteilhaft erscheinen lassen.An advantage of the invention is that the station in which, for reasons of rope dimensioning (course of the rope tension forces, size and location of the greatest and smallest rope tension forces), the basic tension force of the conveyor rope is to be kept constant, is carried out with a fixed drive or deflection sheave can be. For example, this may be an operational requirement for chairlifts with a disc exit, or at least an operational advantage, e.g. for chairlifts with window entry. Likewise, structural or topographical conditions, for example a size of a station location that is too small for a tensioning station with regard to the required tensioning path, can make the use of the tensioning device according to the invention appear advantageous.
Ein weiterer Vorteil der Erfindung ist dadurch gegeben, dass in jener Station, in der aus Gründen der Seilbemessung die Grundspannkraft des Förderseiles konstant gehalten werden soll, keine Energieversorgung für eine Spanneinrichtung der eingangs genannten Art erforderlich ist.Another advantage of the invention is that no energy supply is required for a tensioning device of the type mentioned in that station in which the basic tensioning force of the conveyor rope is to be kept constant for reasons of rope dimensioning.
Besondere Bedeutung erlangt die Erfindung dann, wenn die Bergstation als Spannstation und die Talstation als Gegenstation ausgebildet ist, wobei der Antrieb des Förderseils in der Bergstation erfolgt. In diesem Fall kann durch die erfindungsgemässe Anordnung der Messeinrichtung in der talseitigen Gegenstation der seilbahntechnisch günstige bekannte Fall simuliert werden, wonach der Antrieb in der Bergstation bei fester Antriebsscheibe und die Seilspannung in der Talstation mit Hilfe einer Gewichtsspanneinrichtung erfolgt. Dabei wird aber der für den Einstieg in der Talstation gegebene Nachteil der beweglichen Umlenkscheibe in der Talstation vermieden. Ausserdem sind die aufwendigen bzw. das Landschaftsbild störenden baulichen Massnahmen für die Gewichtsspanneinrichtung entbehrlich.The invention becomes particularly important when the top station is designed as a tensioning station and the bottom station is designed as a counter station, the conveyor cable being driven in the top station. In this case, the arrangement according to the invention of the measuring device in the valley opposite station can simulate the known case, which is favorable in terms of cable car technology, according to which the drive in the mountain station with a fixed drive pulley and the cable tension in the valley station are carried out with the aid of a weight tensioning device. However, this avoids the disadvantage of the movable deflection plate in the valley station, which is an issue for entry into the valley station. In addition, the complex structural measures for the weight tensioning device, which disturb the landscape, are unnecessary.
Wesentliche Vorteile kann die Erfindung auch dann erlangen, wenn die Talstation als Spannstation und die Bergstation als Gegenstation ausgebildet ist, wobei der Antrieb des Förderseils in der Talstation erfolgt. Dies entspricht der herkömmlichen, vom Verlauf der Seilspannkräfte her ebenfalls günstigen Anordnung des Antriebs in der Talstation über eine feste Antriebsscheibe und der Seilspannung in der Bergstation mit Hilfe einer beweglichen Umlenkscheibe und einer Gewichtsspanneinrichtung. Seilbahntechnisch ist dieser Fall insbesondere bei Berg- und Talförderung von Vorteil. Die erfindungsgemässe Realisierung dieses Falles durch Anordnung der Messeinrichtung in der bergseitigen Gegenstation bringt jedoch den zusätzlichen Vorteil einer festen Umlenkscheibe in der Bergstation, was insbesondere die Möglichkeit zur Nutzung eines kleinen bergseitigen Stationsstandortes bietet.The invention can also achieve significant advantages if the valley station is designed as a tensioning station and the mountain station as a counter station, the conveyor cable being driven in the valley station. This corresponds to the conventional arrangement of the drive in the valley station via a fixed drive pulley, which is also favorable in terms of the course of the rope tensioning forces, and the rope tension in the mountain station with the aid of a movable deflection disk and a weight tensioning device. In terms of ropeway technology, this case is particularly advantageous for mountain and valley support. However, realizing this case according to the invention by arranging the measuring device in the mountain-side counter station brings the additional advantage of a fixed deflection disk in the mountain station, which in particular offers the possibility of using a small mountain-side station location.
Vorteile hinsichtlich der Bemessung der Rollenbatterien der Stützen im talnahen Bereich der Seilbahnanlage können durch den weiteren Fall erzielt werden, wonach die Bergstation als Spannstation und die Talstation als Gegenstation ausgebildet ist, der Antrieb des Förderseils aber in der Talstation erfolgt.Advantages with regard to the dimensioning of the roller batteries of the supports in the valley area of the cable car system can be achieved by the further case, according to which the top station is designed as a tensioning station and the bottom station as a counter station, but the conveyor cable is driven in the bottom station.
Die Seilspannung kann zweckmässig mit Hilfe einer Seilwinde erfolgen, deren elektrischer Antriebsmotor von der Regeleinrichtung gesteuert wird. Der Vorteil einer Windenspannung liegt in dem innerhalb weiter Grenzen frei wählbaren Spannweg, während eine hydraulische Spanneinrichtung mit einer engeren Hubbegrenzung behaftet ist. Ausserdem arbeitet der Motor einer Spannseilwinde im Aussetzbetrieb, ist also nicht dauernd belastet, im Gegensatz zu der sich üblicherweise dauernd in Betrieb befindlichen Hydraulikpumpe einer hydraulischen Spanneinrichtung. Trotzdem ist die Erfindung nicht auf eine Spannvorrichtung mit Spannseilwinde beschränkt, sondern umfasst z.B. auch hydraulische Spanneinrichtungen.The rope tension can expediently take place with the aid of a rope winch, the electric drive motor of which is controlled by the control device. The advantage of a winch tension is that the tensioning path can be freely selected within wide limits, while a hydraulic tensioning device has a narrower stroke limitation. In addition, the motor of a tension cable winch operates in intermittent mode, so it is not permanently loaded, in contrast to the hydraulic pump of a hydraulic tensioning device that is usually in continuous operation. Nevertheless, the invention is not limited to a tensioning device with a tension cable winch, but comprises e.g. also hydraulic clamping devices.

In der Spannstation 1 ist die in Längsrichtung der Seilbahn bzw. des Schleppliftes bewegliche Antriebs- oder Umlenkscheibe 2 für das Förderseil 3 über ein Spannseil 4 mit einer elektromotorisch angetriebenen Seilwinde 5 verbunden. Mittels einer in der Gegenstation 6 angeordneten Kraftmesseinrichtung 7 wird die Spannkraft im Förderseil an der festen Antriebs- oder Umlenkscheibe 8 gemessen. Mit Hilfe einer Regeleinrichtung 9 wird die Seilwinde in der Spannstation dahingehend betätigt, dass die Grundspannkraft des Förderseiles an der festen Antriebs- oder Umlenkscheibe der Gegenstation konstant gehalten wird.In the
Die elektronische Regeleinrichtung 9 besteht im wesentlichen aus einem Verstärker, der die Signale von der Messeinrichtung verstärkt, und einem Servorelais, welches den Sollwert und Istwert der Spannkraft vergleicht und über eine Zeitstufe die Schütze des Windenmotors (z.B. 4 bis 5 s) verzögert ansteuert. Ausserdem kann zusätzlich zur eigentlichen Regeleinrichtung-eine Sicherheitsabschaltvorrichtung vorgesehen sein, durch die die Anlage bei bestimmten Abweichungen der Spannkraft vom Nennwert abschaltet, z. B. bei Abweichungen von ±15%.The
Die Kraftmessung in der Kraftmesseinrichtung 7 kann z.B. mit Hilfe von an der Achse der Umlenkscheibe 8 angeordneten Dehnungsmessstreifen oder anderen Widerstandsgebern bzw. mit kapazitiven oder induktiven Gebern erfolgen.The force measurement in the
Eine seilbahntechnisch besonders günstige Anwendung des erfindungsgemässen Lösungsprinzips auf einen Sessellift veranschaulicht Fig. 2. In diesem Fall ist die Bergstation als Spannstation 1 mit beweglicher Antriebsscheibe 2 ausgebildet. Der Antriebsmotor 10 des Förderseils 3 ist ebenfalls in der Bergstation angeordnet. Die Talstation ist als Gegenstation 6 mit fester Umlenkscheibe 8 vorgesehen. Die Seilspannung in der Bergstation erfolgt durch das Spannseil 4 mit Hilfe der Seilwinde 5.

In this case, the mountain station is designed as a
Ein weiteres seilbahntechnisch insbesondere bei Berg- und Talförderung günstiges Anwendungsbeispiel zeigt Fig. 3. In diesem Fall ist die Talstation eines Sessellifts als Spannstation 1 ausgeführt. Auch der Antrieb des Förderseils 3 erfolgt in der Talstation, und zwar mit Hilfe des Antriebsmotors 10, der die bewegliche Antriebsscheibe 2 antreibt. Für die Seilspannung in der Talstation ist wiederum ein Spannseil 4 mit Seilwinde 5 vorgesehen, die vom Elektromotor 11 betrieben wird. Die Schaltung des Elektromotors erfolgt über die Regeleinrichtung, die mit der Messeinrichtung 7 für die Spannkraft des Förderseils 3 in Verbindung steht, wobei die Messeinrichtung 7 in der Bergstation angeordnet ist, die als Gegenstation 6 mit fester Umlenkscheibe 8 ausgebildet ist.FIG. 3 shows another application example that is favorable in terms of ropeway technology, particularly for mountain and valley transportation. In this case, the valley station of a chair lift is designed as a
