Description

Die Erfindung betrifft eine Einrichtung zur Notbremsung von Transportmitteln, insbesondere von Seilbahnen, mittels Reibrädern, die an zumindest einem mit dem Transportmittel verbundenen Reibblech angreifen, wobei mindestens ein Reibrad von einer Ruhestellung, bei der das Reibrad einen Normalabstand vom Reibblech aufweist, in eine Bremsstellung verbringbar ist, indem das Reibrad an zumindest einem beweglichen Träger angebracht ist, welcher durch zumindest eine Hubeinrichtung in Richtung zu bzw. von einem Reibblech beweglich ist.The invention relates to a device for emergency braking of means of transport, in particular of cable cars, by means of friction wheels connected to at least one of the means of transport attack connected friction plate, with at least one friction wheel from a rest position, in which the friction wheel is at a normal distance from the friction plate, into a Braking position can be brought by the friction wheel on at least one movable carrier is attached, which by at least one lifting device in the direction of or is movable by a friction plate.

Es sind mit Reibrädern versehene Verzögerungseinrichtungen bei Seilbahnen bekannt, bei der die Reibräder permanent in einer fixen Lage drehbar und in ständigem Druckkontakt zu den Reibblechen eines an den Reibrädern vorbeifahrenden Transportmittels sind, vor allem auch bei Normalbetrieb, wenn keine Verzögerung der Transportmittel gewünscht wird. Dadurch tritt auch außerhalb der Bremsphasen Verschleiß an der Verzögerungseinrichtung und am Transportmittel auf.Delay devices for cable cars provided with friction wheels are known, where the friction wheels are permanently rotatable in a fixed position and in constant pressure contact to the friction plates of a means of transport passing the friction wheels are, especially during normal operation when there is no delay in the means of transport it is asked for. As a result, wear occurs on the deceleration device even outside the braking phases and on the means of transport.

Die US 4 563 955 zeigt beispielsweise eine solche Seilbahn mit einem Reibradantrieb, bei dem die Reibräder an einer Reibfläche des Transportmittels angreifen und dieses bremsen, beschleunigen oder antreiben.US Pat. No. 4,563,955 shows such a cable car with a friction wheel drive, in which the friction wheels attack a friction surface of the transport means and this brake, accelerate or drive.

Die in der EP 774 392 A1 gezeigte Seilbahnanlage besitzt ebenfalls angetriebene Reibräder (Spalte 2, Zeile13ff), die zum Beschleunigen, Fördern und Verzögern von Transportmitteln verwendet werden, Ein Teil dieser Reibräder kann außer Funktion gesetzt werden, um diesen Bereich der Seilbahnanlage als Speicher für Transportmittel zu nutzen. Wenn diese Reibräder jedoch in Betrieb sind, so geben diese aufgrund der Tatsache, dass sie dann mit einem Antrieb verbunden sind (Spalte 4, Zeile 53ff), für die Transportmittel eine definierte Geschwindigkeit vor.The cable car system shown in EP 774 392 A1 also has driven friction wheels (Column 2, line 13ff), which are used to accelerate, convey and slow down means of transport Some of these friction wheels can be deactivated to this area of the cable car facility as storage for means of transportation use. However, if these friction wheels are in operation, they give due to the The fact that they are then connected to a drive (column 4, lines 53ff) for which Means of transport at a defined speed.

Die US 5 188 037 zeigt eine Seilbahnanlage, bei der die Reibbleche in Längsrichtung Zonen mit unterschiedlichen Reibungskoeffizienten aufweisen. Die US 4 212 702 betrifft eine Notbremseinrichtung für Schienenfahrzeuge, jedoch ohne Verwendung von Reibrädern.The US 5 188 037 shows a cable car system, in which the friction plates in the longitudinal direction Have zones with different coefficients of friction. US 4 212 702 relates an emergency braking device for rail vehicles, but without the use of friction wheels.

Eine Aufgabe der vorliegenden Erfindung besteht nun darin, die Nachteile des Stands der Technik zu überwinden und eine verschleißarme Einrichtung zu entwickeln, die ein bedarfsgerechtes Verzögern, nämlich im Notfall, erlaubt.An object of the present invention is to overcome the disadvantages of the stand overcoming technology and developing a low-wear device that a Delayed as needed, namely in an emergency, allowed.

Die Erfindung ist dadurch gekennzeichnet, dass entweder das antriebslose Reibrad am Träger drehbar befestigt und zwischen Reibrad und Träger eine Vorrichtung zur Übertragung eines einstellbaren Drehmoments angeordnet ist oder dass das Reibrad starr mit dem Träger verbunden ist.The invention is characterized in that either the non-driven friction wheel on Carrier rotatably attached and a device for transmission between the friction wheel and carrier an adjustable torque is arranged or that the friction wheel rigid with is connected to the carrier.

Vorteilhaft an dieser Erfindung ist, dass das oder die Reibräder im Normalbetrieb der Seilbahn nicht mit dem Transportmittel in Eingriff stehen und dadurch auch keine Abnützung erfahren. Erst bei einer gewollten Verzögerung eines Transportmittels, z.B bei einer Fehlkupplung an das Zug- bzw. Förderseil, wird das mindestens eine Reibrad mit einem Reibblech des Transportmittels in Eingriff gebracht. Dabei ist es von Vorteil, wenn mindestens ein Reibrad ruckartig von der Ruhestellung in die Bremsstellung verbringbar ist.The advantage of this invention is that the friction wheel or wheels in normal operation Cable car are not in contact with the means of transport and therefore no wear Experienced. Only when there is an intentional delay in a means of transport, e.g. with a Incorrect coupling to the traction or conveyor cable, that becomes at least one friction wheel with one Friction plate of the means of transport engaged. It is an advantage if at least a friction wheel can be jerked from the rest position to the braking position.

Durch die Anordnung einer Vorrichtung zur Übertragung eines einstellbaren Drehmoments kann die Kraft, mit der das Reibrad verdreht werden kann, und damit die Bremskraft für jedes einzelne Reibrad festgelegt werden. Die vereinfachte Ausführung der Erfindung mit starren, nicht drehbaren Reibrädern hat den Vorteil einer einfachen und kostengünstigen Konstruktion, bewirkt aber eine ungleichmäßige Abnützung der Reibräder.By arranging a device for transmitting an adjustable torque can the force with which the friction wheel can be rotated, and thus the braking force be set for each individual friction wheel. The simplified implementation of the invention with rigid, non-rotatable friction wheels has the advantage of a simple and inexpensive Construction, but causes an uneven wear of the friction wheels.

Durch die Anordnung des Reibrades bzw. der Reibräder an einem Träger kann die Position des Trägers und damit bei mehreren Reibrädern die Position für alle Reibräder einfach und genau festgelegt werden.The position can be determined by arranging the friction wheel or the friction wheels on a carrier the position of the wearer and thus for several friction wheels, the position for all friction wheels is simple and be specified precisely.

Weiters ist vorgesehen, dass der Träger durch zumindest eine Hubeinrichtung in Ruhestellung feststellbar ist.It is also provided that the carrier is in the rest position by at least one lifting device is noticeable.

Dadurch wird der für die Ruhestellung notwendige Abstand zwischen der Lauffläche der Reibräder und einem Reibblech gewährleistet. Vorteilhafterweise werden für das Halten und das Bewegen des Trägers die gleichen Hubeinrichtungen verwendet.As a result, the distance between the tread necessary for the rest position Guaranteed friction wheels and a friction plate. Advantageously, for holding and moving the carrier uses the same lifting devices.

Eine weitere Ausführung der Erfindung sieht vor, dass der Träger zusätzlich mit zumindest einem weiteren kraftbeaufschlagendem mechanischen Element, wie beispielsweise mit Federn, in Eingriff ist, wobei das Element in Richtung der Bremsstellung wirkt.Another embodiment of the invention provides that the carrier additionally with at least a further force-applying mechanical element, such as, for example with springs, is engaged, the element acting in the direction of the braking position.

Dadurch ist sichergestellt, dass einerseits der Träger mit den Reibrädern mit einer bestimmten Kraft auf ein Reibblech wirkt und andererseits bei Ausfall der Hubeinrichtung der Träger mit den Reibrädern automatisch in Bremsstellung gebracht wird, um die Sicherheit der Anlage zu gewährleisten.This ensures that on the one hand the carrier with the friction wheels with a certain Force acts on a friction plate and on the other hand if the lifting device fails the carrier with the friction wheels is automatically brought into the braking position for safety to ensure the system.

Besonders geeignete Hubeinrichtungen stellen hydraulische Hubzylinder dar, die beispielsweise elektrisch gesteuert werden. Als Hubeinrichtungen finden neben hydraulischen Hubzylindern auch elektrische Hubzylinder, elektrohydraulische oder pneumatische Hubeinrichtungen oder andere mechanische Hubgeräte, wie Spindeln, Verwendung.Particularly suitable lifting devices are hydraulic lifting cylinders, for example can be controlled electrically. In addition to hydraulic Lift cylinders also electric lift cylinders, electrohydraulic or pneumatic Lifting devices or other mechanical lifting devices, such as spindles, use.

Betreffend die Vorrichtung zur Übertragung eines einstellbaren Drehmoments ist beispielsweise jedes Reibrad starr mit einer Welle verbunden, wobei zwischen Träger und Welle eine Vorrichtung zur Übertragung eines einstellbaren Drehmoments angeordnet ist.The device for transmitting an adjustable torque is, for example each friction wheel rigidly connected to a shaft, being between the carrier and Shaft a device for transmitting an adjustable torque is arranged is.

Dies kann derart vorgesehen sein, dass die Welle sich in achsialer Richtung über zumindest eine einstellbare vorgespannte Feder und zumindest eine Andrückscheibe an zumindest einem Reibbelag, der fest am Träger angebracht ist, abstützt.This can be provided in such a way that the shaft overlaps at least in the axial direction an adjustable preloaded spring and at least one pressure plate on at least a friction lining, which is firmly attached to the carrier.

Alternativ kann vorgesehen sein, dass die Welle in achsialer Richtung mittels einer Kupplung, wie einer Rutschkupplung oder einer viskosen Kupplung, mit dem Träger in Verbindung steht.Alternatively, it can be provided that the shaft in the axial direction by means of a Coupling, such as a slip clutch or a viscous clutch, with the carrier in Connection is established.

Eine Ausführungsvariante sieht vor, dass das Drehmoment abhängig von der Position der Reibräder vorgebbar ist, wie beispielsweise, dass die Federn für verschiedene Reibräder unterschiedliche Vorspannungen besitzen.An embodiment variant provides that the torque depends on the position the friction wheels can be predetermined, such as that the springs for different friction wheels have different preloads.

Beispielsweise kann durch das Merkmal, dass die Vorspannungen gemäß der Anordnung der Reibräder ansteigen oder abfallen, ein Bremsverlauf mit schwach oder stark ansteigender Bremskraft erzielt werden.For example, the feature that the biases according to the arrangement the friction wheels rise or fall, a braking course with weak or strong increasing braking force can be achieved.

Eine weitere Ausführung der Erfindung besteht darin, dass die Position der Achse von zumindest einem Reibrad bezüglich des Trägers verstellbar ist, vorzugsweise in Richtung zum Reibblech hin bzw. vom Reibblech weg. Dadurch kann ebenfalls ein Bremsverlauf mit unterschiedlicher Bremskraft der einzelnen Reibräder erzielt werden.Another embodiment of the invention is that the position of the axis of at least one friction wheel is adjustable with respect to the carrier, preferably in the direction towards the friction plate or away from the friction plate. This can also result in a braking process can be achieved with different braking force of the individual friction wheels.

Von Vorteil ist, wenn die Reibräder als Luftdruckgummireifen ausgebildet sind. Durch die Dosierung des Luftdrucks ist die Walkarbeit einstellbar und damit die Bremskraft.It is advantageous if the friction wheels are designed as air pressure rubber tires. Through the Dosing of the air pressure, the flexing work is adjustable and thus the braking force.

Durch das Merkmal, dass der Träger mit zumindest einem Ballastgewicht versehen ist, kann das Gewicht der Trägerkonstruktion und damit die Bremskraft verändert werden.Due to the feature that the carrier is provided with at least one ballast weight, the weight of the support structure and thus the braking force can be changed.

Schließlich kann vorgesehen werden, dass die Einrichtung mit einer Prüfeinrichtung, die das Vorliegen eines Notfalls anzeigt, verbunden ist. Dadurch kann beispielsweise automatisch durch ein Signal der Prüfeinrichtung die Notbremsung ausgelöst werden.Finally, it can be provided that the device with a test device, the indicates the presence of an emergency. This can, for example, automatically the emergency braking is triggered by a signal from the test facility.

In Fig. 1 bewegt sich das Transportmittel 1 mittels eines Fahrwerks längs der Transportschiene 12. Diese Situation entspricht beispielsweise einer Station, wo das Transportmittel 1 vom Förderseil auf die Transportschiene 12 wechselt. Das Fahrwerk des Transportmittels 1 weist an der Oberseite ein fix angebrachtes Reibblech 6 auf, das zum Verzögern des Transportmittels 1 mit voneinander im Abstand a angeordneten Reibrädern 2, 13, die als Luftdruckgummireifen ausgebildet sind, in Eingriff gebracht wird. Die Reibräder 2, 13 sind an einem Träger 3 drehbar angeordnet (und weisen in der Ruhestellung einen Abstand b vom Reibblech 6 auf), wobei der Träger 3 von Hubvorrichtungen 4, die mittels Führungen 5 geführt werden, nach oben, vom Reibblech 6 weg, gehoben und während des Normalbetriebs der Transportmittel 1 in dieser Stellung, der Ruhestellung, gehalten wird. Den Hubvorrichtungen 4 wirken dabei vorgespannte Federn 8 sowie das Eigengewicht des Trägers 3 und die Ballastgewichte 7 entgegen.In Fig. 1, the means of transport 1 moves along the transport rail by means of a chassis 12. This situation corresponds, for example, to a station where the means of transport 1 changes from the conveyor cable to the transport rail 12. The chassis of the means of transport 1 has on the top a fixed friction plate 6, which is used for deceleration of the means of transport 1 with friction wheels arranged at a distance a from one another 2, 13, which are designed as air pressure rubber tires, is brought into engagement. The friction wheels 2, 13 are rotatably arranged on a carrier 3 (and point in the rest position a distance b from the friction plate 6), the carrier 3 of lifting devices 4, the are guided by means of guides 5, upwards, away from the friction plate 6, and during normal operation of the transport means 1 in this position, the rest position, is held. The lifting devices 4 act biased springs 8 and that Own weight of the carrier 3 and the ballast weights 7 counter.

Zum Verzögern des Transportmittels 1 wird der Träger 3 mittels der Hubeinrichtungen 4 durch Aufhebung der Hubkraft nach unten in die Bremsstellung abgesenkt, was durch Abschalten bzw. Verringern eines elektrischen Stromes bei elektrischen Hubeinrichtungen oder durch Absenken eines hydraulischen Druckes bei hydraulischen Hubeinrichtungen erfolgt. Durch die fehlende Wirkung der Hubeinrichtungen 4 bewegt sich der Träger soweit nach unten, bis ein oder mehrere Reibräder 2, 13 auf das Reibblech 6 des sich in Bewegung befindlichen Transportmittels 12 drücken. Aufgrund der Kraft, mit der die Reibräder 2, 13 auf das Reibblech 6 drücken, wird die Geschwindigkeit des Transportmittels 1 verringert oder auf Null herabgesetzt. Die Federn 8 üben auf den Träger 3 eine zusätzliche Kraft nach unten aus, ebenso wie die Ballastgewichte 7. Die Federn 8 sind mit ihrer vom Träger 3 abgewandten Seite an einem festen, nicht verschieblichen Bauteil befestigt.To delay the means of transport 1, the carrier 3 is lifted by means of the lifting devices 4 lowered by lifting the lifting force into the braking position, which by Switching off or reducing an electrical current in electrical lifting devices or by lowering a hydraulic pressure in hydraulic lifting devices he follows. Due to the lack of action of the lifting devices 4, the carrier moves so far down until one or more friction wheels 2, 13 on the friction plate 6 of the press moving means 12 in motion. Because of the power with which the friction wheels 2, 13 press on the friction plate 6, the speed of the means of transport 1 decreased or reduced to zero. The springs 8 exercise on the carrier 3 an additional downward force, as well as the ballast weights 7. The springs 8 are with their side facing away from the carrier 3 on a fixed, not movable Component attached.

Die Position der Reibräder 2, 13 bezüglich des Trägers 3 kann, wie bei Reibrad 13 strichliert dargestellt, in Richtung normal zum Reibblech 6 verstellbar sein, sodass durch die Position des einzelnen Reibrades 13 dessen Bremswirkung eingestellt werden kann.The position of the friction wheels 2, 13 with respect to the carrier 3 can, as with the friction wheel 13 shown in dashed lines, adjustable in the direction normal to the friction plate 6, so that by the position of the individual friction wheel 13 whose braking effect can be adjusted.

In Fig. 2 ist dargestellt, dass das Reibblech 6 des Transportmittels 1, das sich längs der Transportschiene 12 bewegt, einen Abstand b zum Reibrad 2 aufweist. Das Reibrad 2 ist, wie die übrigen Reibräder 2, 13, auf einer Welle 11 befestigt. Die Welle 11 ist im Träger 3, welcher durch die Hubeinrichtungen 4 gehalten wird und mit Federn 8 in Eingriff steht, drehbar gelagert und stützt sich in achsialer Richtung über eine vorgespannte Feder 10 und über eine Andrückscheibe 14, die beide fest mit der Welle 11 verbunden sind, auf einem Reibbelag 9 ab.In Fig. 2 it is shown that the friction plate 6 of the transport means 1, which is along the Transport rail 12 moves, has a distance b to the friction wheel 2. The friction wheel 2 is, like the other friction wheels 2, 13, attached to a shaft 11. The shaft 11 is in the carrier 3, which is held by the lifting devices 4 and engages with springs 8 stands, rotatably mounted and is supported in the axial direction via a preloaded spring 10 and via a pressure plate 14, both of which are firmly connected to the shaft 11 are on a friction lining 9.

Selbstverständlich sind auch Ausführungen mit mehreren Anordnungen von Federn 10, Reibbelägen 9 und Andrückscheiben 14 möglich, beispielsweise je eine Anordnung zu beiden Seiten des Trägers (3). Ebenso können statt diesen Anordnungen eine oder zwei Kupplungen, wie Rutschkupplungen oder viskose Kupplungen, pro Welle zur Übertragung des Drehmoments verwendet werden.Of course, versions with multiple arrangements of springs 10 are also Friction linings 9 and pressure plates 14 possible, for example one arrangement each both sides of the carrier (3). Likewise, one or two can be used instead of these arrangements Couplings, such as slip clutches or viscous clutches, per shaft for transmission of the torque can be used.

  • the force of one or more springs 8
  • the resistance of the lifting devices
  • the size of the air pressure of a friction wheel designed as an air pressure rubber tire
  • the dead weight of the support structure consisting of the support, the friction wheels, the shafts, etc.
  • the weight of one or more ballast weights.

Dass die Reibräder, solange keine Verzögerung erforderlich ist, still und nicht in Kontakt mit dem Fahrzeug stehen, hat gegenüber dem Stand der Technik folgenden Vorteil: es tritt kein mechanischer Verschleiß der Einrichtung und keine zusätzliche mechanische Beanspruchung der Transportmittel beim Durchfahren der Einrichtung auf, solange keine Bremsung erforderlich ist. That the friction wheels are silent and not in contact as long as no delay is required standing with the vehicle has the following advantage over the prior art: it there is no mechanical wear on the device and no additional mechanical Stress on the means of transport when driving through the facility, as long as none Braking is required.

Weiters ist vorteilhaft, dass die Bremswirkung unabhängig von der Fahrtrichtung ist.It is also advantageous that the braking effect is independent of the direction of travel.

Da die Reibräder untereinander nicht mechanisch verbunden sind, wie etwa bei bekannten Einrichtungen die Reibräder mittels Keilriemen, Zahnriemen, Wellen, Getrieben oder Kupplungen verdrehbar und verdrehsteif verbunden sind, können die einzelnen Reibräder in der Höhe unterschiedlich justiert werden. Alternativ oder zusätzlich kann die Vorspannung der Federn 10, die auf die Reibbeläge wirken, unterschiedlich eingestellt werden. Durch diese Maßnahmen kann ein Bremsverlauf mit schwach oder stark ansteigender Bremskraft erreicht werden.Since the friction wheels are not mechanically connected to each other, as is the case with known ones Set up the friction wheels using V-belts, toothed belts, shafts, gears or couplings are rotatably and torsionally rigid connected, the individual The height of the friction wheels can be adjusted differently. Alternatively or additionally, the Biasing of the springs 10, which act on the friction linings, is set differently become. Through these measures, a braking process with a weak or strong increase Braking force can be achieved.

Die Einrichtung weist die erforderliche Betriebssicherheit auf, da bei Ausfall einer erfindungsgemäß angeordneten Hubeinrichtung der Träger aufgrund des Gewichts nach unten fällt bzw. die Federn 8 den Träger 3 nach unten drücken und dadurch die Reibräder in die Bremsstellung gebracht werden.The device has the required operational reliability, because if one fails according to the invention arranged lifting device of the carrier due to the weight falls down or the springs 8 press the carrier 3 down and thereby the friction wheels be brought into the braking position.

Die erfindungsgemäße Einrichtung kann bei allen Transportanlagen, wo ein Transportmittel auf einer festen Fahrbahn fährt, wie auf einer oder mehreren Schienen oder auf einem oder mehreren Tragseilen, eingesetzt werden. Sie eignet sich insbesondere für eine Umlaufseilbahn mit Transportmitteln, welche keine Notbremseinrichtung besitzen. Hier wird im Falle einer Fehlkupplung, bei der die Seilklemme des Transportmittels dieses nicht fest mit dem Zug- bzw. Förderseil verbindet, etwa bei Ausfahrt aus der Station, das Transportmittel zum Stillstand gebracht.The device according to the invention can be used in all transport systems where a means of transport runs on a solid road, such as on one or more rails or on one or more suspension cables. It is particularly suitable for a cable car with means of transport that do not have an emergency braking device. Here is in the case of a wrong coupling, in which the cable clamp of the means of transport this not firmly connected to the train or conveyor cable, e.g. when leaving the station, brought the means of transport to a standstill.
