Description

Spanneinrichtung für Förderseile von Seilbahnen und Schleppliften Tensioning device for conveyor ropes of cable cars and drag lifts
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 Spanneinriσhtung, wobei der Antrieb der Spanneinrichturig 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 in the hoisting rope is kept constant.
Charakteristik des bekannten Standes der TechnikCharacteristic of the known prior art
Es sind Spanneinrichtungen mit einer elektromotorisch angetriebenen Seilwinde für ein Spannseil bekannt geworden, bei denen die Messung der Kraft, mit der dasTensioning devices with an electric motor driven winch for a tensioning rope have become known, in which the measurement of the force with which the
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 hydraulischenConveyor rope is tensioned by measuring the rope tension force in the tension rope. As a result of this arrangement of the force measuring device, it is the same with a tensioning device of the type mentioned at the beginning as with a weight tensioning device and with a hydraulic one
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 device of the known type only possible to keep the basic tensioning force constant in the conveyor cable in the tensioning station, that is to say in the station with a movable drive or deflection disk.
Aufgabe der ErfindungObject of the invention
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. Darlegung des Wesens der ErfindungIt seems desirable to create a tensioning device which 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. State the nature of the invention
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Meßeinrichtung für die Spannkraft in der Gegenstation (Station mit der festen Antriebs- oder Umlenksσheibe) angeordnet ist.This object is achieved in that the measuring device for the clamping force is arranged in the opposite station (station with the fixed drive or deflection disc).
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 beispielsweise bei Sesselbahnen mit Scheibenausstieg ein betriebliches Erfordernis, zmindest 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 erforderliche 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 the basic tensioning force of the conveyor rope is to be kept constant for reasons of rope dimensioning (course of the rope tensioning forces, size and location of the occurrence of the largest and smallest rope tensioning forces) with a fixed drive or deflection sheave can be. This can be an operational requirement for chairlifts with a disc exit, for example, 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 eineAnother advantage of the invention is that in that station in which the basic tensioning force of the conveyor rope is to be kept constant for reasons of rope dimensioning, no energy supply for one
Spanneinrichtung der eingangs genannten Art erforderlich ist. 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 erfindungsgeraäße Anordnung der Meßeinrichtung in der talseitigen Gegenstation der seilbahntechnisσh 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.Clamping device of the type mentioned is required. The invention becomes particularly important if 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, by the arrangement of the measuring device according to the invention in the valley-side counter station of the cable car technology, known, favorable case can be simulated, according to which the drive in the mountain station with a fixed drive pulley and the cable tension in the valley station take place 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 when entering the valley station. In addition, the complex structural measures for the weight tensioning device, which disturb the landscape, can be dispensed with.
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, von Verlauf derThe 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 conveying cable being driven in the valley station. This corresponds to the conventional, from course of
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 Talfδrderung 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.Rope tensioning forces also favorable arrangement of the drive in the valley station via a fixed drive pulley and the rope tension in the mountain station with the help of a movable deflection pulley and a weight tensioning device. In terms of ropeway technology, this case is particularly advantageous for mountain and valley transportation. 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 plate 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 area of the cable car system near the valley can be achieved by the further case, after 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 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 be carried out 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 lies in the tension path that 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 operation, 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.

Mittels einer in der Gegenstation 6 angeordneten Kraftmeßeinrichtung 7 wird die Spannkraft im Förderseil an der festen Antriebs- oder Ümlenkscheibe 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 tensioning station 1 is the drive or movable in the longitudinal direction of the cable car or the drag lift Deflection pulley 2 for the conveyor cable 3 is connected to an electric motor driven cable winch 5 via a tensioning cable 4. By means of a force measuring device 7 arranged in the counter station 6, the tensioning force in the conveyor cable is measured on the fixed drive or deflecting pulley 8. With the help of a control device 9, the cable winch in the tensioning station is actuated in such a way that the basic tensioning force of the conveyor rope on the fixed drive or deflection pulley of the opposite station is kept constant.
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 sek) 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 electronic control device 9 consists essentially of an amplifier which amplifies the signals from the measuring device and a servo relay which compares the setpoint and actual value of the clamping force and controls the contactors of the winch motor with a delay (e.g. 4 to 5 seconds) with a delay. In addition to the actual control device, a safety shutdown device can be provided, by means of which the system switches off in the event of certain deviations in the clamping force from the nominal value, e.g. with deviations of ± 15%.
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 force measuring device 7 can e.g. with the aid of strain gauges arranged on the axis of the deflection disk 8, or other resistance sensors or with capacitive or inductive sensors.

In this case, the mountain station is designed as a tensioning station 1 with a movable drive pulley 2. The drive motor 10 of the conveyor cable 3 is also arranged in the mountain station. The valley station is provided as a counter station 6 with a fixed deflection plate 8. The rope tension in the mountain station is done by the tension rope 4 with the help of the winch 5. The Electric motor 11 of the cable winch 5 is switched by the control device 9, which is connected to the force measuring device in the opposite station 6.
