Die gegenständliche Erfindung betrifft eine Einrichtung zur Prüfung der Klemmkraft, welche von der Kupplungseinrichtung für das Fahrbetriebsmittel einer Seilbahnanlage auf das Trag- und Förderseil ausgeübt wird, wobei die Kupplungseinrichtung mit einem unter Wirkung eines Federspeichers stehenden Klemmhebel ausgebildet ist, an welchem eine längs einer Lauffläche einer Führungsschiene abrollende Betätigungsrolle gelagert ist, wobei die Lauffläche mit einem elastisch verformbaren Bereich ausgebildet ist, welchem eine Messeinrichtung zugeordnet ist, durch welche die Verformung der Lauffläche aufgrund der durch den Federspeicher erzeugten und über die Betätigungsrolle auf die Führungsfläche wirkenden, der Klemmkraft entsprechenden Druckkraft messbar ist.The subject invention relates to a device for testing the clamping force, which of the coupling means for the driving means of a cable car system is exerted on the supporting and conveying cable, wherein the coupling device with a formed under the action of a spring accumulator clamping lever, on which a bearing along a running surface of a guide rail rolling actuator roller is, wherein the tread is formed with an elastically deformable region, which a measuring device is assigned, by which the deformation of the tread due to the generated by the spring accumulator and the actuating roller on the Guide surface acting, the clamping force corresponding pressure force is measurable.
Es ist eine Einrichtung zur Prüfung der Klemmkraft einer Kupplungseinrichtung bekannt,
bei welcher die durch den Federspeicher auf das Trag- und Förderseil wirkende
Klemmkraft der Kupplungseinrichtung dadurch geprüft wird, daß ein zweiter Federspeicher
vorgesehen ist, durch welchen im Fall, daß die durch den ersten Federspeicher aufgebrachte
Druckkraft nicht hinreichend groß ist, ein Stellhebel verschwenkt wird, durch
welchen ein Schalter zur Abstellung der Seilbahnanlage betätigt wird.
Durch diese Einrichtung zur Klemmkraftprüfung wird jedoch ein sehr hoher Wartungsaufwand
bedingt.There is a device for testing the clamping force of a coupling device is known in which the force acting on the support and hoisting rope through the spring force clamping force of the coupling device is characterized in that a second spring memory is provided, through which in the case that by the first spring accumulator applied pressure force is not sufficiently large, an adjusting lever is pivoted, through which a switch is actuated for the shutdown of the cable car system.
However, this device for Klemmkraftprüfung a very high maintenance is required.
Aus der EP-A1 0181244 ist eine elektronisch wirkende Einrichtung zur Klemmkraftprüfung bekannt, bei welcher an der Lauffläche einer Führungsschiene für eine an einem verschwenkbaren Klemmhebel angeordnete Betätigungsrolle ein unter Wirkung der durch die Betätigungsrolle ausgeübten Druckkraft elastisch verformbarer Bereich vorgesehen ist, welchem ein elektronisches Messgerät zugeordnet ist, durch welches die Verformung dieses Bereiches messbar ist. Da das Ausmaß der Verformung dieses Bereiches der Lauffläche von der Größe der von der Betätigungsrolle auf die Lauffläche ausgeübten Druckkraft abhängig ist, welche ihrerseits der Größe der von der Kupplungseinrichtung auf das Trag- und Förderseil ausgeübten Klemmkraft entspricht, kann durch das elektronische Messgerät die Klemmkraft ermittelt bzw. überprüft werden. From EP-A1 0181244 is an electronically acting device for clamping force testing in which at the tread of a guide rail for a on a pivotable clamping lever arranged actuating roller under the effect of provided by the actuating roller pressure force elastically deformable area provided is, which is associated with an electronic measuring device through which the deformation this range is measurable. Because the extent of deformation of this area the tread on the size of the applied by the actuating roller on the tread Compressive force is dependent, which in turn the size of the clutch device on the carrying and conveying rope applied clamping force, can by the electronic Measuring device, the clamping force can be determined or checked.
Obgleich diese bekannte Einrichtung gegenüber einer mechanischen Klemmkraftprüfung vorteilhaft ist, entspricht sie jedoch deshalb nicht den bestehenden Erfordernissen, da durch ein einziges elektronisches Messgerät die erforderliche Funktionssicherheit nicht gewährleistet ist. Die vermeintlich naheliegende Lösung dieses Problems, eine Mehrzahl von elektronischen Messgeräten zur Ermittlung der Verformung des Messbereiches der Lauffläche vorzusehen, ist deshalb nicht anwendbar, da sich die elektronischen Messgeräte gegenseitig beeinflussen, wodurch die erforderliche Funktionssicherheit gleichfalls nicht gegeben ist.Although this known device compared to a mechanical clamping force test advantageous, however, it does not therefore comply with the existing requirements, because of a single electronic measuring device the required reliability is not guaranteed. The supposedly obvious solution to this problem, a Plurality of electronic measuring instruments to determine the deformation of the measuring range the tread is therefore not applicable, since the electronic Measuring instruments influence each other, creating the required reliability is also not given.

Dabei sind jedoch zwei voneinander im Abstand befindliche Detektoren erforderlich, welche beide für sich voll funktionsfähig sein müssen. Soferne demgegenüber einer dieser beiden Detektoren nicht voll funktionsfähig ist, wird durch diese Einrichtung gleichfalls kein den Erfordernissen entsprechendes Messergebnis erzielt.From FR-A1 2750764 a device for clamping force testing is also known, which is formed with two infrared detectors, by means of which the distances from two points of the clamping lever to respective fixed points in different Schwenklagen the clamping lever are measured, whereby the size of the Clamping force can be determined. However, there are two spaced from each other Detectors required, both of which must be fully functional. Unless In contrast, one of these two detectors is not fully functional, is by This device also achieved no measurement results corresponding to the requirements.
Der gegenständlichen Erfindung liegt somit die Aufgabe zugrunde, eine Einrichtung zur
elektronischen Klemmkraftprüfung zu schaffen, durch welche die den bekannten Einrichtungen
anhaftenden Nachteile vermieden werden. Dies wird erfindungsgemäß dadurch
erzielt, dass die Messeinrichtung durch mindestens zwei in ihrer Wirkungsweise
unterschiedliche Messgeräte gebildet ist, welche innerhalb des elastisch verformbaren
Bereiches in Bewegungsrichtung der Betätigungsrolle nebeneinander bzw. hintereinander
angeordnet sind.
Da zwei unmittelbar nebeneinander befindliche Messgeräte vorgesehen sind, ist die
Funktionssicherheit der Prüfeinrichtung gewährleistet. Eine gegenseitige Beeinflussung
dieser beiden Messgeräte wird dadurch vermieden, dass sie in ihrer Wirkungsweise unterschiedlich
sind.The subject invention is therefore based on the object to provide a device for electronic clamping force test, by which the disadvantages of the known devices are avoided. This is inventively achieved in that the measuring device is formed by at least two different in their operation measuring devices, which are arranged within the elastically deformable region in the direction of movement of the actuating roller side by side or one behind the other.
Since two directly adjacent measuring devices are provided, the reliability of the test device is guaranteed. A mutual influence of these two measuring devices is avoided by being different in their mode of action.
Vorzugsweise sind mindestens drei Messgeräte vorgesehen, welche in Bewegungsrichtung der Betätigungsrolle nebeneinander und bzw. oder hintereinander angeordnet sind.Preferably, at least three measuring devices are provided, which in the direction of movement the actuating roller side by side and or or are arranged one behind the other.
Vorzugsweise wird die mindestens zwei Messgeräte auf unterschiedliche Oszillatorfrequenzen abgestellt. Dabei können die mindestens zwei Messgeräte durch induktive Messwertgeber gebildet sein, deren Oszillatoren auf unterschiedliche Frequenzen abgestellt sind. Weiters können die mindestens zwei Messgeräte durch kapazitive Messwertgeber gebildet sein, deren Oszillatoren auf unterschiedliche Frequenzen abgestellt sind. Zudem können die mindestens zwei Messgeräte durch Ultraschallgeräte gebildet sein, deren Oszillatorfrequenzen unterschiedlich sind. Weiters können die mindestens zwei Messgeräte durch Lichtmessgeräte gebildet sein, welche mit unterschiedlichen Pulsfrequenzen arbeiten. Schließlich kann jeweils eines der Messgeräte als induktiver Messwertgeber, als kapazitiver Messwertgeber, als Ultraschallgeber und bzw. oder als Lichtmessgerät ausgebildet sein.Preferably, the at least two measuring devices are at different oscillator frequencies switched off. The at least two measuring devices can be inductive Transmitter may be formed whose oscillators turned off at different frequencies are. Furthermore, the at least two measuring devices can be controlled by capacitive measuring sensors be formed, whose oscillators are turned off at different frequencies. In addition, the at least two measuring devices can be formed by ultrasound devices, whose oscillator frequencies are different. Furthermore, the at least two Measuring devices may be formed by light measuring devices, which with different pulse frequencies work. Finally, one of the measuring devices can be used as inductive measuring transmitter, as a capacitive transmitter, as an ultrasonic generator and / or as a light meter be educated.

In Fig.1 ist eine Anlage zur Ermittlung der vom Federspeicher einer krupplungseinrichtung
aufgebrachten und auf das Trag- und Förderseil 1 einer
Seilbahnanlage wirkenden Klemmkraft dargestellt. Diese Anlage weist eine
Laufschiene 2 für das Laufwerk 3 eines an einer Tragstange 41 angeordneten
Fahrbetriebsmittels 4 auf. Am Laufwerk 3 sind Laufrollen 31 vorgesehen,
mittels welcher das Fahrbetriebsmittel 4 längs der in den Stationen vorgesehenen
Schienen 2 verfahrbar ist. Zudem ist am Laufwerk 3 eine Kupplungseinrichtung
vorgesehen, mittels welcher das Fahrbetriebsmittel 4 an das
Trag- und Förderseil 1 ankuppelbar ist.In Figure 1 is a system for determining the spring of a nip device
applied and on the support and hoisting rope 1 a
Cableway system acting clamping force shown. This plant has a
Die bewegliche Kuppelbacke ist mit einem Stellhebel ausgebildet, welcher
unter Wirkung eines Federspeichers steht und durch welchen die für die
Kupplung mit dem Trag- und Förderseil 1 erforderliche Klemmkraft aufgebracht
wird. Am freien Ende des Stellhebels ist eine Betätigungsrolle 5 gelagert,
welche längs einer Steuerschiene 6 abrollt. Zur Prüfung der vom Federspeicher
aufgebrachten Klemmkraft ist eine Meßeinrichtung 7 vorgesehen. Im
Falle, daß die Klemmkraft nicht hinreichend groß ist, wird die Seilbahnanlage
. durch die Meßeinrichtung 7 abgestellt.
Eine derartige Anlage ist aus dem Stand der Technik bekannt.The movable coupling jaw is formed with a control lever which is under the action of a spring accumulator and through which the required for the coupling with the support and hoisting
Such a system is known from the prior art.
Wie dies aus Fig.2 ersichtlich ist, besteht die erfindungsgemäße Meßeinrichtung
7 darin, daß in der Lauffläche 61 der Steuerschiene 6 für die Betätigungsrolle
5 des Kupplungshebels ein Bereich 62 vorgesehen ist, welcher
elastisch verformbar ist, wobei diesem Bereich 62 der Lauffläche 61 zwei
Meßgeräte 71, 72 zugeordnet sind. Die Steuerschiene 6 ist T-förmig ausgebildet,
wobei sie aus einem Steg 63 und der an diesem angeordneten Lauffläche
61 besteht. Im Bereich der Meßgeräte 71, 72 ist der Steg 63 entfernt, wobei
in der dadurch gebildeten Ausnehmung 73 die zwei Meßgeräte 71, 72
angeordnet sind. Im Bereich 62 ist die Lauffläche 61 deshalb, da sie durch
den Steg 63 nicht abgestützt ist, unter Wirkung des auf die Betätigungsrolle
5 wirkenden Federspeichers verformbar, wodurch sich deren Abstand zu
den Meßgeräten 71, 72 ändert. Diese Änderung im Abstand, welche ein Maß
für die Druckkraft bzw. für die Klemmkraft darstellt, ist durch die elektronischen
Meßgeräte 71, 72 erfaßbar, wodurch die Klemmkraft überprüfbar ist. As can be seen from Figure 2, there is the measuring device according to the
Um die angestrebte Funktionssicherheit zu gewährleisten, besteht das Erfordernis, mehrere Meßgeräte anzuordnen, wobei jedoch gewährleistet sein muß, daß sich diese in ihrer Funktion nicht beeinflussen.In order to ensure the desired functional safety, there is a need to arrange several meters, but it must be ensured that that these do not affect their function.
Wie dies aus Fig.3 ersichtlich ist, sind zwei Meßgeräte 71 und 72 vorgesehen,
welche quer zur Laufrichtung der am Kupplungshebel 51 gelagerten Betätigungsrolle
5 nebeneinander angeordnet sind und deren Ausgänge an eine
Steuereinheit 70 gelegt sind. Um jedoch deren voneinander unabhängige
Funktionen zu gewährleisten, müssen diese beiden elektronischen Meßgeräte
71 und 72 unterschiedliche Oszillatorfrequenzen aufweisen. Als Oszillatorfrequenzen
werden insbesondere 330 kHz und 360 kHz eingesetzt. Die Oszillatorfrequenzen
können dabei in einem sehr großen Bereich gewählt werden.
Maßgeblich dabei ist, daß die Frequenzen der nebeneinander angeordneten
Meßgeräte unterschiedlich sind, um hierdurch deren gegenseitige Beeinflussung
auszuschließen.As can be seen from FIG. 3, two
Als elektronische Meßgeräte können induktive Meßwertgeber, kapazitive Meßwertgeber und Ultraschall-Geber eingesetzt werden, deren Oszillationsfrequenzen jeweils unterschiedlich sind. Zudem können Lichtmeßgeräte eingesetzt werden, welche mit unterschiedlichen Pulsfrequenzen betrieben werden. Dabei können entweder gleichartige Meßgeräte eingesetzt werden, welche mit unterschiedlichen Frequenzen betrieben werden oder es können in ihrer Art unterschiedliche Meßgeräte, z.B. ein induktiver Meßwertgeber und ein kapazitiver Meßwertgeber, eingesetzt werden.As electronic measuring devices inductive transducers, capacitive Transducers and ultrasonic encoders are used, their oscillation frequencies each are different. In addition, light measuring devices can be used be operated with different pulse frequencies. Either similar measuring instruments can be used, which can be operated with different frequencies or it can be used in different types of instruments, e.g. an inductive transmitter and a capacitive transmitter, are used.

nebeneinander oder in Bewegungsrichtung der Betätigungsrolle 5 hintereinander
angeordnet sein. Durch eine vermehrte Anzahl von Meßgeräten wird
die Sicherheit im Ergebnis der Messung erhöht.The measuring devices can transversely to the direction of movement of the actuating roller. 5
