Die vorliegende Erfindung betrifft eine Seilbahn mit einem Fernsteuerungssystem, insbesondere für den Transport von Material wie beispielsweise Holz gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a cable car with a remote control system, in particular for the transport of material such as wood, according to the preamble of patent claim 1.

Es sind verschiedene Arten von Seilbahnen mit Laufwagen mit unterschiedlichen Arten der Seilführung bekannt. Im Allgemeinen sind Laufwagen bekannt, die an das Seil gebunden sind und sich durch die Verschiebung des Tragseils bewegen, mit dem sie fest verbunden sind.Various types of cable cars with carriages with different types of cable routing are known. In general, carriages are known which are tied to the cable and move by the displacement of the carrying cable to which they are fixed.

Eine zweite Art von Laufwagen verfügt über einen Antrieb, der die Laufwagen direkt auf dem Tragseil bewegt.A second type of carriage has a drive that moves the carriage directly on the suspension cable.

Bei einer dritten Variante laufen die Laufwagen am Tragseil entlang und werden durch ein Zugseil über eine stationäre Winde bewegt.In a third variant, the carriages run along the carrying cable and are moved by a traction cable via a stationary winch.

Die vorliegende Erfindung betrifft Seilbahnanlagen mit Laufwagen, die sich auf Seilen bewegen, insbesondere von einem Tragseil getragen werden und sich mittels eines sogenannten Zugseils bewegen, das vorzugsweise unterhalb des Tragseils angeordnet ist. Das bedeutet, dass die Laufwagen z. B. mittels Rollen auf dem Tragseil bewegt werden und die Bewegung mittels eines an den Laufwagen angeordneten Antriebssystems für ein Zugseil, das ein nicht bewegliches Seil ist, erfolgt und den Laufwagen zieht. Dieser Laufwagen verfügt vorzugsweise über eine Winde zum Anheben und/oder Abladen von Material, z. B. Bäumen und dergleichen.The present invention relates to cable car systems with carriages that move on cables, in particular are carried by a supporting cable and move by means of a so-called traction cable, which is preferably arranged below the supporting cable. This means that the carriage z. B. be moved by means of rollers on the support cable and the movement by means of a arranged on the carriage drive system for a traction cable, which is a non-movable cable, and pulls the carriage. This carriage preferably has a winch for lifting and/or offloading material, e.g. As trees and the like.

Das System wird häufig mit Hilfe eines Geräts ferngesteuert, dass Fernsignale sendet, z. B. einer Funkfernsteuerung oder ähnlichem. Während der Benutzung kann der Benutzer, der den selbstfahrenden Wagen steuert, den Kontakt mit dem Wagen verlieren, und in diesem Fall befindet sich der selbstfahrende Wagen nicht mehr unter der direkten Kontrolle des Benutzers, was mit den Risiken eines solchen Kontrollverlusts verbunden ist.The system is often remotely controlled using a device that sends remote signals, e.g. B. a radio remote control or the like. During use, the user controlling the self-propelled car may lose contact with the car, and in this case the self-propelled car is no longer under the user's direct control, which entails the risks of such loss of control.

DE 352 8655 enthält einen selbstfahrenden Wagen, der über eine Funkfernbedienung gesteuert werden kann, und diese Steuerung aktiviert ein Hydrauliksystem am selbstfahrenden Wagen. Es werden keine zusätzlichen Sicherheitssysteme zur Steuerung des selbstfahrenden Wagens veröffentlicht. DE 352 8655 contains a self-propelled cart that can be controlled via a radio remote control, and this control activates a hydraulic system on the self-propelled cart. No additional safety systems to control the self-propelled car are released.

Die DE 20 2010 008 078 enthält ein Sicherheitssystem für Kranlaufwagen, das mittels einer Fernsteuerung betrieben wird und ein Sicherheitssystem mit einem Seil zum Abbremsen der Katze aufweist. Diese Art von Sicherheitssystem ist für Krane geeignet, bei denen der Verfahrweg der Katze begrenzt ist.the DE 20 2010 008 078 Contains a safety system for crane trolleys, which is operated by means of a remote control and has a safety system with a rope to brake the trolley. This type of safety system is suitable for cranes where the travel of the trolley is limited.

In der EP 0 250 392 wird ebenfalls ein System beschrieben, mit dem der selbstfahrende Wagen ferngesteuert wird, aber auch in dieser Veröffentlichung sind Ersatzsysteme für die Fernsteuerung vorgesehen.In the EP 0 250 392 also describes a system for remotely controlling the self-propelled car, but substitute systems for the remote control are also provided in this publication.

Keines der bisher beschriebenen Systeme veröffentlicht ein zweites und/oder alternatives System, mit dem die Steuerung des selbstfahrenden Wagens übernommen werden kann, um eine größere Signalfernübertragung zu gewährleisten.None of the systems described so far disclose a second and/or alternative system for controlling the self-propelled Wagens can be taken over to ensure greater long-distance signal transmission.

In der vorliegenden Beschreibung und den beigefügten Ansprüchen bedeutet "im Wesentlichen" eine Abweichung des Winkels plus oder minus 5° und der Länge plus oder minus 5% der Länge des angegebenen Objekts.As used in the present specification and appended claims, "substantially" means a deviation of angle plus or minus 5° and length plus or minus 5% of the length of the specified object.

Aufgabe der vorliegenden Erfindung ist es, ein Steuerungssystem für eine Seilbahn mit mindestens einem Tragseil und mindestens einem Zugseil mit einem selbstfahrenden Laufwagen zu realisieren, die einen Aktuator zur Bewegung entlang des Seils aufweist.The object of the present invention is to implement a control system for a cableway with at least one suspension cable and at least one traction cable with a self-propelled carriage that has an actuator for movement along the cable.

Diese Aufgabe wird durch eine Seilbahnanlage mit einem Fernsteuerungssystem, insbesondere für den Transport von Material wie Holz, nach Anspruch 1 gelöst.This object is achieved by a cable car system with a remote control system, in particular for the transport of material such as wood, according to claim 1.

Erfindungsgemäß wird eine Seilbahnanlage mit einem Fernsteuerungssystem mit mindestens einem Tragseil und mindestens einem Zugseil, die zwischen einer talwärts und einer bergwärts gelegenen Station angeordnet sind, und mit einem selbstfahrenden Laufwagen vorgeschlagen, der einen Tragrahmen aufweist, der mittels mindestens einer Tragrolle an einem Tragseil beweglich ist, an dem mindestens ein Stellantrieb angeordnet ist.According to the invention, a cable car system is proposed with a remote control system with at least one support cable and at least one traction cable, which are arranged between a downhill station and an uphill station, and with a self-propelled carriage that has a support frame that can be moved by means of at least one support roller on a support cable , on which at least one actuator is arranged.

Erfindungsgemäß ist auf dem selbstfahrenden Laufwagen mindestens eine Datenkommunikationseinrichtung zum Senden und Empfangen von Signalen einer Steuereinheit von einer Steuereinrichtung angeordnet, und ist zwischen mindestens zwei Seilen eine Signalsende-/Empfangseinrichtung zwischengeschaltet , die mittels der Seile auf dem selbstfahrenden Laufwagen Signale sendet und empfängt, und ist mindestens eine Signalsende-/Empfangseinrichtung zwischen denselben zwei Seilen an einer Station, vorzugsweise an einer talabwärts und/oder bergwärts gelegenen Station, angeordnet, und bilden die beiden Einrichtungen und die Seile einen Kommunikationskreis, wobei auch mehr als ein Kommunikationskreis vorhanden sein kann.According to the invention, at least one data communication device for sending and receiving signals from a control unit is arranged on the self-propelled carriage from a control device, and a signal transmission/reception device is interposed between at least two cables, which sends and receives signals by means of the cables on the self-propelled carriage, and is at least one Signal transmitting/receiving device is arranged between the same two cables at a station, preferably at a station located down the valley and/or up the mountain, and the two devices and the cables form a communication circuit, it also being possible for there to be more than one communication circuit.

Diese Kommunikation kann realisiert werden, da es keinen Kurzschluss zwischen den Seilen gibt. Durch die mindestens zwei zwischen den beiden Seilen angeordneten Kommunikationseinrichtungen wird mindestens ein Kommunikationskreislauf realisiert, es können jedoch auch mehrere Kreisläufe z.B. mit der nach- und vorgelagerten Station vorhanden sein.This communication can be realized because there is no short circuit between the ropes. At least one communication circuit is implemented by the at least two communication devices arranged between the two cables, but there can also be several circuits, e.g. with the downstream and upstream station.

Diese Seilkommunikation wird vorzugsweise als Hilfssystem eingesetzt, d. h. sie kommt nur dann zum Einsatz, wenn kein Signal vom Bediener/Benutzer vorliegt, d. h. wenn sich der Laufwagen bzw. Schlitten außerhalb des Sendebereichs des Bedieners/Benutzers befindet.This cable communication is preferably used as an auxiliary system, i. H. it is only used when there is no signal from the operator/user, ie. H. when the carriage or carriage is outside the transmission range of the operator/user.

Der selbstfahrende Wagen kann vorzugsweise mit einem elektrisch betriebenen Handhabungs- und/oder Hebesystem ausgestattet sein. Der Aktuator kann auch ein Stromgenerator sein, z. B. wenn eine Last durch die Winde abgesenkt wird, wird elektrische Energie erzeugt, und diese elektrische Energie kann in eine Batterie eingespeist werden, die das Kommunikationssystem über die Seile mit Strom versorgt und/oder das Kommunikationssystem direkt über die Seile mit Strom versorgt.The self-propelled trolley can preferably be equipped with an electrically operated handling and/or lifting system. The actuator can also be a power generator, e.g. when a load is lowered by the winch, electrical energy is generated and this electrical energy can be fed into a battery that powers the communication system via the cables and/or powers the communication system directly via the cables.

Um ein Seil vom anderen zu isolieren, kann es natürlich auch genügen, wenn nur ein Seil von dem Laufwagen isoliert wird, während das andere Seil in Kontakt mit dem Laufwagen bleibt.In order to insulate one rope from the other, it can of course also be sufficient if only one rope from the carriage is isolated while the other rope remains in contact with the carriage.

In einer weiteren Ausführungsform können mehrere Tragseile vorhanden sein, von denen eines z. B. elektrisch isoliert ist.In a further embodiment, several suspension cables may be present, one of which z. B. is electrically isolated.

An den Enden der Seile und/oder an den Signaleinspeisestationen können auch Geräte angeordnet sein, die das Signal in das/die Seil(e) einspeisen und/oder empfangen. Der elektrische Strom wird in variablen Abständen eingespeist. Über die variable Stromversorgung wird das Signal eingespeist, das dann von den Einheiten in der Station und/oder auf dem Wagen erfasst wird und aus dem die Befehle/Informationen zur Steuerung des Wagens abgeleitet werden.Devices which feed and/or receive the signal into the cable(s) can also be arranged at the ends of the cables and/or at the signal feeding stations. The electric current is fed in at variable intervals. The variable power supply feeds the signal which is then picked up by the units in the station and/or on the wagon and from which the commands/information to control the wagon are derived.

Dieses Kommunikationssystem ermöglicht es, einige Bytes pro Sekunde zu senden, die ausreichen, um den selbstfahrenden Wagen und alle auf dem Wagen angebrachten Vorrichtungen wie Winde und Greifvorrichtungen, Überwachungsvorrichtungen usw. fernzusteuern.This communication system makes it possible to send a few bytes per second, which is enough to remotely control the self-propelled trolley and all the devices installed on the trolley, such as winches and gripping devices, monitoring devices, etc.

In der nachgelagerten und/oder vorgelagerten Basisstation sind vorzugsweise Einrichtungen zum Empfangen/Senden von Signalen so angeordnet, dass auch Mittel zur drahtlosen Signalübertragung vorhanden sind. Da normalerweise immer ein Bediener im Umkreis der nach- oder vorgelagerten Station anwesend ist, ermöglicht das oben beschriebene System die Kommunikation mit dem Bediener. Das beschriebene System ermöglicht die Kommunikation mit dem Wagen auch dann, wenn er sich außerhalb der Reichweite der Fernsteuerungseinrichtung befindet, da die Kommunikation über die Seile erfolgt, mit denen immer ein Kontakt besteht.Devices for receiving/transmitting signals are preferably arranged in the downstream and/or upstream base station in such a way that there are also means for wireless signal transmission. Since there is normally always an operator present in the perimeter of the downstream or upstream station, the system described above enables communication with the operator. The system described enables communication with the car even if it is out of range of the remote control device, since the Communication takes place via the ropes, with which there is always contact.

Die reguläre Kommunikation erfolgt in einer bevorzugten Ausführungsform über die Fernkommunikationseinrichtung erst dann, wenn diese nicht mehr in Kontakt mit dem Fahrzeug steht. Das System auf dem Wagen und/oder das System in einer Station aktiviert das Kommunikationssystem über die Seile.In a preferred embodiment, the regular communication only takes place via the long-distance communication device when it is no longer in contact with the vehicle. The system on the carriage and/or the system in a station activates the communication system via the cables.

Es kann vorgesehen werden, dass das System in bestimmten Abständen oder nach der Installation des Systems Signale über die Seile sendet, um zu überprüfen, ob das System funktioniert.The system can be arranged to send signals down the cables at certain intervals or after the system has been installed to check that the system is working.

In Abbildung 1 ist ein Seilbahnsystem mit mindestens zwei Seilen 102 und 103, die zwischen einer Talstation und einer Bergstation angeordnet sind, mit der Bezugsziffer 100 gekennzeichnet. Natürlich sind auch Zwischenstationen möglich, in denen Datenempfangs- und/oder -sendegeräte zwischen dem Benutzer/Bediener und dem Wagen angeordnet werden können.In illustration 1 a cable car system with at least two cables 102 and 103, which are arranged between a valley station and a mountain station, is identified by the reference number 100. Intermediate stations are of course also possible, in which data receiving and/or transmitting devices can be arranged between the user/operator and the trolley.

Ein selbstfahrender Wagen 101 läuft auf mindestens einem Tragseil 102 mittels Tragrollen 106. In der vorliegenden Ausführungsform sind die Rollen 106 und/oder die Verbindung zwischen den Rollen und dem Laufwagen 101 elektrisch isoliert. Zwischen den beiden Seilen 102 und 103 ist eine Signalempfangseinrichtung 105 an dem selbstfahrenden Laufwagen und mindestens eine Signalempfangseinrichtung 203 an einer nach- oder vorgelagerten Station angeordnet. Erfindungsgemäß ist es lediglich erforderlich, dass zwischen mindestens zwei Seilen 102, 103 eine Signalempfangs-Sendeeinrichtung 105 auf dem selbstfahrenden Wagen und mindestens eine Signalempfangs-Sendeeinrichtung 203 in einer nach- oder vorgelagerten Station zwischengeschaltet ist.A self-propelled carriage 101 runs on at least one support cable 102 by means of support rollers 106. In the present embodiment, the rollers 106 and/or the connection between the rollers and the carriage 101 are electrically insulated. Between the two cables 102 and 103 there is a signal receiving device 105 on the self-propelled carriage and at least one signal receiving device 203 on a downstream or upstream station. According to the invention it is only necessary that between at least two cables 102, 103 a signal receiving and transmitting device 105 on the self-propelled carriage and at least one signal receiving and transmitting device 203 is interposed in a downstream or upstream station.

Der selbstfahrende Laufwagen 101 verfügt über mindestens einen Aktuator, der den Laufwagen entlang des Tragseils 102 in der dargestellten Ausführungsform mit Hilfe von Antriebsrollen 107 bewegt, die mit einem Schleppseil 103 zusammenwirken und den selbstfahrende Laufwagen 101 bewegen. Vorzugsweise handelt es sich bei dem Antrieb um einen Elektromotor, der auch als Stromgenerator fungieren kann und Strom erzeugt, wenn der Wagen beispielsweise bergabwärts fährt.The self-propelled carriage 101 has at least one actuator that moves the carriage along the support cable 102 in the illustrated embodiment with the aid of drive rollers 107 that interact with a tow cable 103 and move the self-propelled carriage 101 . The drive is preferably an electric motor, which can also function as a power generator and generates power when the car is driving downhill, for example.

Vorteilhafterweise treibt der Elektromotor oder ein weiterer Elektromotor das am Wagen 101 angeordnete Hebesystem an und auch in diesem Fall kann beim Absenken der Last durch das Hebesystem elektrischer Strom erzeugt werden, der direkt vom System genutzt werden kann oder eine am Wagen angeordnete Batterie versorgt.Advantageously, the electric motor or another electric motor drives the lifting system arranged on the carriage 101 and also in this case, when the load is lowered by the lifting system, electrical current can be generated which can be used directly by the system or supplies a battery arranged on the carriage.
