Description

Die Erfindung betrifft eine betrieblich lösbare Klemmvorrichtung, insbesondere für Seilumlaufbahnen, mit mindestens einer das Seil mittels zweier Backen umfassenden Klemme, wobei mindestens eine Backe durch wenigstens eine Druckfeder an das Seil andrückbar bzw. von diesem durch einen vorzugsweise schwenkbaren und an einer ortsfesten Schiene auflaufenden Hebel abhebbar ist, sowie mit mindestens einer Prüffeder, welche der Druckfeder entgegenwirkt, und mit einer Einrichtung, welche die Verformung der Prüffeder bei an das Seil angeklemmter Backe mißt und bei Überschreiten eines vorgegebenen Wertes eine Signal- und/oder Anhaltevorrichtung zum Ansprechen bringt.The invention relates to an operationally releasable clamping device, in particular for cable orbits, with at least one clamp comprising the rope by means of two jaws, at least one jaw being able to be pressed against the rope by at least one compression spring or by means of a preferably pivotable lever that runs against a stationary rail can be lifted off, as well as with at least one test spring, which counteracts the compression spring, and with a device, which measures the deformation of the test spring when the jaw is clamped on the rope and, if a predetermined value is exceeded, triggers a signal and / or stopping device to respond.

Die Verformung der Prüffeder ist dabei ein Maß für die Kraft der die Klemmung bewirkenden Druckfeder. Diese Kraft kann sowohl durch Alterung der Druckfeder oder durch Bruch einzelner Elemente derselben als auch durch Abnutzung der beweglichen Verbindungen zwischen Druckfeder und Klemmbacke im Lauf der Zeit abnehmen.The deformation of the test spring is a measure of the force of the compression spring causing the clamping. This force can decrease over time both due to the aging of the compression spring or due to the breakage of individual elements of the same as well as due to the wear of the movable connections between the compression spring and the jaw.

Bei einer bekannten Vorrichtung der genannten Art ist die ortsfeste Schiene über eine Feder abgestützt, welche durch die Kraft der auf die Schiene auflaufenden Rolle des Abhebemechanismus zusammengedrückt wird. Unterschreitet diese Kraft einen vorgegebenen Wert, so wird diese Feder nicht mehr oder nur unvollständig zusammengedrückt, wodurch die Weiterfahrt dieses Gehänges unterbunden wird. Ein Nachteil dieser Vorrichtung besteht darin, daß sie empfindlich gegen Schwenkbewegungen des Gehänges ist, so daß es durch dynamische Einflüsse zu Fehlschaltungen kommen kann. Weiters wird die Kraft der Andrückfeder im abgeklemmten Zustand gemessen, während für die Sicherheit der Klemmung die Kraft bei angeklemmtem Gehänge maßgebend ist.In a known device of the type mentioned, the stationary rail is supported by a spring which is compressed by the force of the roller of the lifting mechanism which runs onto the rail. If this force falls below a predetermined value, this spring is no longer compressed or is compressed only incompletely, as a result of which this suspension is prevented from continuing to travel. A disadvantage of this device is that it is sensitive to pivoting movements of the hanger, so that incorrect switching can occur due to dynamic influences. Furthermore, the force of the pressure spring is measured in the disconnected state, while the force when the hanger is clamped is decisive for the safety of the clamping.

Ziel der Erfindung ist es, eine Klemmvorrichtung mit einer Prüfeinrichtung für die Klemmkraft zu schaffen, durch welche unbeeinflußt durch Bewegungen des Gehänges und unabhängig von dessen Geschwindigkeit die Klemmkraft der Backen im angeklemmten Zustand überprüft wird. Erfindungsgemäß wird dies dadurch erreicht, daß die Prüffeder im Andrückmechanismus angeordnet ist.The aim of the invention is to provide a clamping device with a To create a test device for the clamping force, through which the clamping force of the jaws is checked in the clamped state unaffected by movements of the hanger and regardless of its speed. According to the invention, this is achieved in that the test spring is arranged in the pressing mechanism.

Damit werden die Prüfelemente in die Nähe der Klemmbacken gerückt und Übertragungsfehler statischer und dynamischer Art weitestgehend ausgeschaltet.This moves the test elements close to the jaws and largely eliminates static and dynamic transmission errors.

Die Erfindung wird nun anhand der Figuren näher erläutert. Der Schutz soll sich jedoch nicht auf diese mögliche Verwirklichung des Erfindungsgedankens beschränken, insbesondere haben die Bezugsziffern nur erläuternden Charakter.The invention will now be explained in more detail with reference to the figures. However, protection is not intended to be limited to this possible realization of the inventive concept; in particular, the reference numbers are only of an explanatory nature.

Fig. 1 stellt einen Längsschnitt durch eine erfindungsgemäße Klemmvorrichtung dar, wobei die Teile in der Lage gezeichnet sind, in der sie sich bei ausreichender Kraft des Druckfederpaketes bei an das Seil angedrückter Klemmbacke befinden. Die Fig. 2 stellt ebenfalls im Längsschnitt die Lage der Teile bei unzureichender Klemmkraft dar. Die Figuren 3 und 4 zeigen in einem Ausschnitt je eine Variante, Fig. 5 stellt eine für diese abgeänderte Form der Prüffeder dar.Fig. 1 shows a longitudinal section through a clamping device according to the invention, the parts being drawn in the position in which they are with sufficient force of the compression spring assembly with the jaw pressed against the rope. 2 also shows in longitudinal section the position of the parts with insufficient clamping force. FIGS. 3 and 4 each show a variant in a detail, FIG. 5 shows a modified form of the test spring for this.

Wie die Fig. 1 und 2 erkennen lassen, weist das Gehänge des Liftes an seinem oberen Ende ein Rohrstück 2 auf, welches um eine Achse 3 drehbar gelagert ist, um Pendelbewegungen in "Fahrtrichtung zu ermöglichen. Quer zur Fahrtrichtung wird ein unerwünschtes Ausschwenken durch eine am freien Ende der Achse 3 gelagerte Rolle 4 verhindert, welche in einer in der Station angebrachten Führungsschiene 5 abläuft.As can be seen in FIGS. 1 and 2, the hanger of the lift has at its upper end a pipe section 2 which is rotatably mounted about an axis 3 in order to enable pendulum movements in the "direction of travel. An undesired swiveling out by a at the free end of the axis 3 mounted roller 4 prevented, which runs in a guide rail 5 attached in the station.

Die Achse 3 ist in einen Klemmenkasten eingesetzt, welcher aus einem U-förmigen Teil 6 und zwei Stirnplatten 7 bzw. 8 besteht. Bei 9 ist eine Rolle des Laufwerkes und die entsprechende Fahrschiene angedeutet, womit bei vom Seil gelöstem Sessel dieser unterstützt wird.The axis 3 is inserted in a terminal box, which consists of a U-shaped part 6 and two end plates 7 and 8 consists. At 9, a role of the running gear and the corresponding travel rail are indicated, with which this is supported when the chair is released from the rope.

An einem Fortsatz des Klemmenkastens ist der feste Klemmbacken 10 befestigt. Der bewegliche Klemmbacken 11 ist um einen Bolzen 12 drehbar gelagert. An seinem dem Klemmenkasten zugewandten Ende ist .er mittels eines Bolzens 13 an ein schräg angeordnetes Druckstück 14 angelenkt, welches seinerseits mittels eines Bolzens 15 mit einer im Klemmenkasten längsverschieblich gelagerten Stange 16 verbunden ist. An einem Absatz 17 dieser Stange liegt ein Tellerfederpaket 18 an, welches die Stange 16 in Richtung auf die Klemmbacken zu schieben versucht, so daß über das Druckstück 14 der bewegliche Klemmbacken 11 an das Seil 19 gedrückt wird. Die Geometrie und die Federkraft sind dabei so gewählt, daß bei ungünstigsten Bedingungen eine etwa dreifache Sicherheit gegen Rutschen vorhanden ist.The fixed clamping jaw 10 is fastened to an extension of the terminal box. The movable clamping jaw 11 is rotatably mounted about a bolt 12. At its end facing the terminal box, it is articulated by means of a bolt 13 to an obliquely arranged pressure piece 14, which in turn is connected by means of a bolt 15 to a rod 16 which is mounted in the terminal box in a longitudinally displaceable manner. At a shoulder 17 of this rod there is a plate spring assembly 18 which tries to push the rod 16 in the direction of the clamping jaws, so that the movable clamping jaw 11 is pressed against the cable 19 via the pressure piece 14. The geometry and the spring force are chosen so that there is approximately three times the security against slipping under the most unfavorable conditions.

Zum Lösen der Klemmverbindung in der Station wird die Stange 16 entgegen der Kraft des Federpaketes 18 bewegt. Dies erfolgt mittels eines drehbar gelagerten Hebels 20, der an seinem einen Ende durch eine Lasche 21 mit der Stange 16 verbunden ist und an seinem anderen Ende eine Rolle 22 trägt, welche auf eine nicht dargestellte Schiene in der Station aufläuft.To release the clamp connection in the station, the rod 16 is moved against the force of the spring assembly 18. This is done by means of a rotatably mounted lever 20 which is connected at one end to the rod 16 by a tab 21 and at its other end carries a roller 22 which runs onto a rail, not shown, in the station.

Um bei jedem Klemmvorgang zu prüfen, ob das Federpaket 18 die vorgesehene Kraft ausübt, stützt sich dieses an der Stirnplatte 7 nicht direkt, sondern über eine topfförmige, in der Stirnplatte 7 längsverschieblich geführte Hülse 23 ab. Diese ist mit mehreren axial verlaufenden Bohrungen zur Aufnahme von Schraubenfedern 24 versehen, welche sich an der Stirnplatte 7 abstützen.In order to check with each clamping operation whether the spring assembly 18 exerts the intended force, this is not supported directly on the end plate 7, but rather via a cup-shaped sleeve 23 guided in the end plate 7 in a longitudinally displaceable manner. This is provided with a plurality of axially running bores for receiving helical springs 24, which are supported on the end plate 7.

Die Druckfedern 18 und die Prüffedern 14 stützen sich-. demnach gemeinsam auf einem Widerlager ab, welches durch die Hülse 23 gebildet wird.The compression springs 18 and the test springs 14 are supported. accordingly, together on an abutment, which is formed by the sleeve 23.

Die Gesamtkraft dieser Prüffedern 24 wird so gewählt, daß sie wenig kleiner als jene des Federpaketes 18 ist, wenn die untere Toleranzgrenze der Federkraft erreicht ist. Ist bei an das Seil 19 angeklemmtem Gehänge die Kraft des Federpaketes 18 kleiner als jene der Prüffedern 24, so bewegt sich dadurch die Hülse 23 in Richtung auf das Seil 19 hin, wie dies in Fig. 2 dargestellt ist. Die Größe "x" der Verschiebung ist dabei ein Maß für die Unterschreitung der erforderlichen Federkraft.The total force of these test springs 24 is chosen so that it is slightly less than that of the spring assembly 18 when the lower tolerance limit of the spring force is reached. If the force of the spring assembly 18 is smaller than that of the test springs 24 when the hanger is clamped to the rope 19, the sleeve 23 thereby moves in the direction of the rope 19, as shown in FIG. 2. The size "x" of the displacement is a measure of the falling below the required spring force.

Überschreitet diese Verschiebung ein vorgegebenes Maß, so wird dadurch eine Ausschaltung der Anlage und/oder eine Signalabgabe bewirkt. Dazu ist an der Hülse 23 ein stangenartiger Fortsatz 25 befestigt, welcher einen Schalthebel 26 verdreht. Am Ausgang der Station, wo die Rolle 22 von der (nicht dargestellten) Schiene bereits wieder abgelaufen ist, ist ein ortsfester Schalter 27 angebracht, welcher durch ein drehbares Schaltstück 28 betätigt wird. Dieses ist so angeordnet, daß bei ausreichender Kraft des Federpaketes 18 der Schalthebel 26 sich neben dem Schaltstück 28 vorbeibewegt (Fig. 1). Hat jedoch, wie in Fig.2 dargestellt, die Kraft des Federpaketes 18 so weit abgenommen, daß die Prüffedern 24 die Hülse 23 um ein gewisses Maß verschoben haben, so wird der Schalthebel 26 nach unten verdreht und er stößt an das Schaltstück 28. Damit wird die Ausschaltung der Anlage und/oder ein Signal ausgelöst.If this shift exceeds a predetermined level, this causes the system to be switched off and / or a signal to be emitted. For this purpose, a rod-like extension 25 is attached to the sleeve 23, which rotates a shift lever 26. At the exit of the station, where the roller 22 has already run off the rail (not shown), a stationary switch 27 is attached, which is actuated by a rotatable switching element 28. This is arranged so that with sufficient force of the spring assembly 18, the shift lever 26 moves past the switching piece 28 (Fig. 1). However, as shown in Fig.2, the force of the spring assembly 18 has decreased so much that the test springs 24 have shifted the sleeve 23 to a certain extent, the shift lever 26 is rotated downward and it abuts the contact piece 28 the system is switched off and / or a signal is triggered.

Bei der Ausführung nach Fig. 3 erfolgt die Messung der Verformung der Prüffeder 24 über einen verdrehbaren Teil. Das Widerlager 23 weist an seiner der Druckfeder 18 abgewandten Seite auf einem Kreisring angeordnete kegelförmige Vertiefungen 29' zur Aufnahme von Kugeln 30 auf, welche durch einen Käfig 31 auf Abstand gehalten werden und sich an einer Druckplatte 32 abstützen, welche ebenfalls den Kugeln 30 entsprechende Vertiefungen 29" aufweist. Die Druckplatte 32 ist mittels eines Axiallagers 33 über eine Buchse 34 an der Stirnplatte 7 des Klemmengehäuses drehbar gelagert. Eine Drehfeder 24 greift mit ihren Enden in entsprechende Bohrungen der Druckplatte bzw. der Stirnplatte 7 ein. Das Widerlager 23 ist mittels eines Querstiftes 35 und eines Langloches 36 in der Stange 16 gegen Verdrehen gesichert, kann sich jedoch in Längsrichtung verschieben. Ebenso wie in der Ausführung nach den Fig. 1 und 2 ist am Widerlager 23 ein hier nicht dargestelltes Kupplungsstück und ein Anschlag befestigt.3, the deformation of the test spring 24 is measured via a rotatable part. The abutment 23 has on its side facing away from the compression spring 18 on a circular ring arranged conical depressions 29 'for receiving balls 30, which are held at a distance by a cage 31 and attached to each other Support a pressure plate 32, which also has recesses 29 "corresponding to the balls 30. The pressure plate 32 is rotatably supported by means of an axial bearing 33 via a bushing 34 on the end plate 7 of the terminal housing the end plate 7. The abutment 23 is secured against rotation by means of a transverse pin 35 and an elongated hole 36 in the rod 16. However, it can move in the longitudinal direction, just as in the embodiment according to FIGS Coupling not shown here and a stop attached.

Die Prüffeder 24 wird so stark vorgespannt, daß sie bei ausreichender Kraft der Druckfeder 18 nicht imstande ist, die Druckplatte 32 zu verdrehen. Sinkt jedoch die Kraft der Druckfeder unter den vorgegebenen Wert, so rasten die Kugeln 30 durch die Verdrehung der Druckplatte 32 aus den Vertiefungen 29' bzw.29" aus und das Widerlager 23 wird axial verschoben, wodurch über das Kupplungsstück 25, den Anschlag 26 und das Betätigungsglied 28 der Schalter 27 zum Ansprechen gebracht wird.The test spring 24 is biased so much that it is unable to rotate the pressure plate 32 with sufficient force of the compression spring 18. However, if the force of the compression spring drops below the predetermined value, the balls 30 snap out of the recesses 29 'or 29 "by rotating the pressure plate 32 and the abutment 23 is displaced axially, as a result of which the coupling piece 25, the stop 26 and the actuator 28 of the switch 27 is activated.

Wie die Fig. 4 zeigt, kann auch die Druckfeder einschließlich des Widerlagers drehbar gelagert werden, so daß eine Verdrehsicherung entfallen kann. Die Druckfeder stützt sich an ihrem dem Widerlager 23 abgewandten Ende nicht direkt, sondern über ein Axiallager 33 an der Stange 16 ab. Die Druckplatte 30 stützt sich an der Stirnplatte 7 ab, wobei sie auf nicht dargestellte Art, beispielsweise durch einen Stift, gegen Verdrehen gesichert ist. Das Kupplungsstück 25 ist so ausgebildet, daß es eine Verdrehung des Widerlagers 23 zuläßt; beispielsweise kann es gleitend an diesem anliegen. Die Prüffeder 24 greift mit ihren Enden in entsprechende Bohrungen im Widerlager 23 bzw. in der Stirnplatte 7 ein.As shown in Fig. 4, the compression spring including the abutment can be rotatably mounted, so that an anti-rotation device can be omitted. The compression spring is not supported directly at its end facing away from the abutment 23, but via an axial bearing 33 on the rod 16. The pressure plate 30 is supported on the end plate 7, being secured against rotation in a manner not shown, for example by a pin. The coupling piece 25 is designed so that it allows rotation of the abutment 23; for example, it can slide against it. The ends of the test spring 24 engage in corresponding bores in the abutment 23 or in the end plate 7.

Wie die Fig. 5 zeigt, kann anstelle der Drehfeder die Prüffeder 24 auch als Schraubenfeder ausgebildet sein, welche sich einerseits am U-förmigen Teil 6 des Klemmengehäuses und anderseits an einem Fortsatz 37 der Druckplatte 32 (Ausführung nach Fig. 3) bzw. des Widerlagers 23 (Ausführung nach Fig. 4) abstützt. Vorzugsweise werden mehrere über den Umfang verteilte Prüffeder angeordnet.5 shows, instead of the torsion spring, the test spring 24 can also be designed as a helical spring, which is located on the one hand on the U-shaped part 6 of the terminal housing and on the other hand on an extension 37 of the pressure plate 32 (embodiment according to FIG. 3) or Abutment 23 (execution according to FIG. 4) is supported. A plurality of test springs distributed over the circumference are preferably arranged.

Im Rahmen der Erfindung sind zahlreiche Varianten möglich. So könnte beispielsweise die Verschiebung der Hülse nicht mechanisch, sondern elektronisch, optisch, magnetisch usw. auf den ortsfesten. Schalter übertragen werden. Weiters könnte auch die Prüffeder als Tellerfederpaket ausgebildet werden, was allerd.ings die erforderliche Länge vergrößern würde. Schließlich ist die Verwirklichung des erfindungsgemäßen Prinzips nicht auf eine Klemme mit nur einer beweglichen Backe beschränkt; es läßt sich auch bei zwei beweglichen Backen sowie in Gondelbahnen mit Doppelklemmen anwenden.Numerous variants are possible within the scope of the invention. For example, the sleeve could not be moved mechanically, but electronically, optically, magnetically etc. on the stationary one. Switches are transmitted. Furthermore, the test spring could also be designed as a plate spring package, which would, however, increase the required length. Finally, the implementation of the principle according to the invention is not limited to a clamp with only one movable jaw; it can also be used with two movable jaws and in gondola lifts with double clamps.
