Description

Leitungswagen zum Verfahren an einer Schiene  Cable trolley for moving on a rail
Die Erfindung betrifft einen Leitungswagen zum Verfahren an einer Schiene gemäß den Merkmalen im Oberbegriff von Patentanspruch 1. The invention relates to a cable trolley for the method on a rail according to the features in the preamble of claim 1.
Leitungswagen als entlang einer Schiene verfahrbare Elemente einer Kabelwagenanlage dienen der sicheren und ordnungsgemäßen Nachführung von Leitungen, welche mit einem beweglichen Verbraucher verbunden sind. Standardmäßig erfolgt das richtungsgebundene Verfahren der Leitungswagen mechanisch, wobei die entlang der Schiene hintereinander angeordneten und unmittelbar benachbarten Leitungswagen über Zugelemente miteinander verbunden sind, so dass der sich bewegende Verbraucher die Leitungswagen hinter sich her zieht oder schiebt. Cable trolleys as along a rail movable elements of a cable car system are used for the safe and proper tracking of lines that are connected to a mobile consumer. By default, the directional process of the cable trolleys takes place mechanically, wherein the along the rail successively arranged and immediately adjacent cable trolleys are connected to each other via tension elements, so that the moving consumer pulls the cable trolley behind him or pushes.
Die zum Verbraucher führenden Leitungen werden in durchhängenden Schlaufen von Laufwagen zu Laufwagen geführt, deren Durchhangtiefe je nach Abstand der Leitungswagen untereinander variiert. Je nach Ausführung der Kabelwagenanlage werden so Geschwindigkeiten des Verbrauchers bis 240 Meter pro Minute realisiert. Bei erhöhten Anforderungen durch hohe Geschwindigkeiten und Leitungsgewichten, wie sie beispielsweise im Kranbau oder bei Transportanlagen vorzufinden sind, werden angetriebene Leitungswagen eingesetzt. Durch das gezielte Ansteuern dieser Leitungswagen über das Fahrsignal der Krankatze werden die dynamischen Belastungen reduziert, was einen leitungsschonenderen Betrieb ermöglicht. The lines leading to the consumer are guided in slack loops from carriage to carriage, the depth of which varies depending on the distance between the cable trolleys. Depending on the design of the cable car system, speeds of the consumer up to 240 meters per minute can be achieved. In the case of increased requirements due to high speeds and line weights, as found, for example, in crane construction or in transport systems, powered cable trolleys are used. The selective control of these cable trolleys on the driving signal of the trolley, the dynamic loads are reduced, allowing a line-friendly operation.
Motorisiert angetriebene Leitungswagen sind bereits seit Jahren bekannt. Um die notwendige Verfahrgeschwindigkeit zu regeln, werden die Antriebe über Frequenzumrichter drehzahlgesteuert. Motorized driven cable trolleys have been known for years. In order to regulate the necessary travel speed, the drives are speed-controlled via frequency converters.
Die DE 44 36 520 C1 beschreibt hierzu einen angetriebenen Wagen zum Aufhängen und Verfahren an einer Schiene. Der Antrieb erfolgt über einen Motor mit durchgehender Antriebswelle, welcher quer zur Verfahrrichtung des Wagens angeordnet ist. Beide Enden der Antriebswelle sind jeweils über einen Riementrieb mit Tragrollen verbunden, über die der Wagen auf der Schiene verfahrbar ist. DE 44 36 520 C1 describes this purpose a powered carriage for hanging and method on a rail. The drive is via a motor with a continuous drive shaft, which is arranged transversely to the direction of travel of the carriage. Both ends of the drive shaft are each connected via a belt drive with carrying rollers over which the carriage is moved on the rail.
Die DE 1 042 857 B offenbart einen Leitungswagen mit einem Antriebsmotor, dessen einseitiges Antriebsende über ein Zahnradgetriebe die Laufrollen antreibt. DE 1 042 857 B discloses a cable trolley with a drive motor whose one-sided drive end drives the rollers via a gear transmission.
Da derartige Systeme mitunter in schlecht zugänglichen Höhenlagen sowie der Witterung ausgesetzten Außenbereichen eingesetzt werden, ist ein hoher Anspruch insbesondere an die Wartungsfreundlichkeit des verwendeten Riementriebs zu richten. Auch im Hinblick auf die Produktion derartiger Leitungswagen lässt der mitunter fertigungs- und platzintensive Riemenantrieb Raum für Verbesserungen. Since such systems are sometimes used in difficult to reach altitudes and the weather-exposed outdoor areas, a high standard is to be directed in particular to the ease of maintenance of the belt drive used. Also with regard to the production of such cable trolleys, the sometimes production- and space-intensive belt drive leaves room for improvement.
Der Erfindung liegt somit die Aufgabe zugrunde, einen Leitungswagen zum Verfahren an einer Schiene aufzuzeigen, welcher mit einem geringeren Wartungs-, Fertigungs- sowie Platzaufwand angetrieben werden kann. The invention is therefore based on the object to show a cable trolley for moving to a rail, which can be driven with a lower maintenance, manufacturing and space requirements.
Die Lösung dieser Aufgabe besteht nach der Erfindung in einem Leitungswagen gemäß den Merkmalen nach Anspruch 1. Vorteilhafte Weiterbildungen sind Gegenstand der jeweils abhängigen Ansprüche 2 bis 11. The solution to this problem consists according to the invention in a cable trolley according to the features of claim 1. Advantageous developments are the subject of the respective dependent claims 2 to 11.
Die Erfindung betrifft einen Leitungswagen zum Verfahren an einer Schiene, welcher mehrere Laufrollen sowie mindestens einen Antriebsmotor mit beidseitigen Antriebsenden aufweist. Erfindungsgemäß treiben die beiden Antriebsenden jeweils über ein Zahnradgetriebe eine der Laufrollen an. Durch die antriebstechnische Verbindung des Antriebsmotors mit dem den Leitungswagen antreibenden Laufrollen über ein Zahnradgetriebe, entsteht ein gekapseltes System, welches alle Vorteile eines wartungsfreundlichen und witterungsunabhängigen Antriebs bietet. The invention relates to a cable trolley for moving on a rail, which has a plurality of rollers and at least one drive motor with drive ends on both sides. According to the invention drive the two drive ends in each case via a gear transmission to one of the rollers. By the drive connection of the drive motor with the cable cars driving rollers via a gear transmission, creates an enclosed system, which offers all the benefits of a maintenance-friendly and weather-independent drive.
Gegenüber einem Riemenantrieb wird somit eine deutlich höhere Standzeit erreicht, welche ohne Nachspannen oder Austausch eines Riemens auskommt. Das direkte Abgreifen des Drehmoments an beiden Antriebsenden des Antriebsmotors ermöglicht hierbei einen ausgewogenen und überaus platzsparenden Antriebsaufbau. Compared to a belt drive thus a significantly longer service life is achieved, which requires no retightening or replacement of a belt. The direct tapping of the torque at both drive ends of the drive motor in this case allows a balanced and extremely space-saving drive structure.
Um ein möglichst kompaktes System zu erhalten, ist die Ausrichtung des Antriebsmotors so gewählt, dass die Antriebsenden mit ihrer Rotationsachse parallel zur Verfahrrichtung des Leitungswagens ausgerichtet sind. In Kombination mit Zahnradgetrieben in Form von Winkelgetrieben ergibt sich somit ein schlanker sowie kurzbauender Antriebsstrang. In order to obtain a compact system as possible, the orientation of the drive motor is chosen so that the drive ends are aligned with its axis of rotation parallel to the direction of travel of the festoon carriage. In combination with gear drives in the form of angular gears thus results in a slimmer and short-building powertrain.
Die über den Antriebsmotor angetriebenen Laufrollen sind auf einer Längsseite der Schiene angeordnet. Hierdurch wird das Drehmoment des Antriebsmotors auf kürzestem Weg auf die Laufrollen übertragen, um einen möglichst verlustarmen und mit nur wenig beweglichen und umlenkenden Elementen auskommenden Antrieb zu erhalten. The driven by the drive motor rollers are arranged on one longitudinal side of the rail. As a result, the torque of the drive motor is transmitted over the shortest path to the rollers in order to obtain as low-loss and with only a small amount of movable and deflecting elements running out drive.
In einer vorteilhaften Ausgestaltung ist auf beiden Längsseiten der Schiene jeweils ein Antriebsmotor angeordnet. Durch die spiegelsymmetrische Anordnung der Antriebsmotoren auf beiden Seiten der Verfahrrichtung ergibt sich ein ausbalanciertes Antriebssystem. Die zum Verfahren des Leitungswagens notwendige Leistung verteilt sich hierbei auf zwei voneinander getrennt arbeitende Antriebsmotoren, wodurch diese die benötigte Leistung untereinander aufteilen und somit gegenüber dem Einsatz eines einzelnen Antriebsmotors kleiner bauen. Überdies bleibt der Leitungswagen auch bei Ausfall einer der Antriebsmotoren weiterhin verfahrbar und kann aus eigener Kraft in eine Wartungsposition verbracht werden. In an advantageous embodiment, a drive motor is arranged on both longitudinal sides of the rail. The mirror-symmetrical arrangement of the drive motors on both sides of the travel direction results in a balanced drive system. The procedure of the Festoon necessary power is distributed here on two separately operating drive motors, which they split the power required among themselves and thus build smaller compared to the use of a single drive motor. Moreover, the cable trolley remains mobile even if one of the drive motors fails and can be moved out of its own power into a maintenance position.
Auch in dieser Ausgestaltung sind die über die beiden Antriebsmotoren angetriebenen Laufrollen auf beiden Längsseiten der Schiene angeordnet. Somit wird das Drehmoment der Antriebsmotoren auf kürzestem Weg auf die Laufrollen übertragen, um einen möglichst verlustarmen und mit nur wenig beweglichen und umlenkenden Elementen auskommenden Antrieb zu erhalten. Also in this embodiment, the rollers driven by the two drive motors are arranged on both longitudinal sides of the rail. Thus, the torque of the drive motors is transmitted by the shortest route to the rollers in order to obtain as low-loss and with only a small amount of moving and deflecting elements coming out drive.
Vorteilhaft weist der Leitungswagen ein Fahrgestell auf. An diesem werden alle erforderlichen Elemente des Antriebs montiert, wodurch sich eine verfahrbare Einheit ergibt. Das Fahrgestell selbst dient der Aufnahme weiterer Bauteile, wie beispielsweise Anschlagpuffer oder Zugösen. Advantageously, the cable trolley on a chassis. At this all necessary elements of the drive are mounted, resulting in a movable unit. The chassis itself serves to accommodate other components, such as bumpers or drawbar eyes.
Um einen bestimmungsgemäßen Einsatz des Leitungswagens zu erreichen, ist vorgesehen, dass das Fahrgestell eine Leitungstrage aufweist. Im unteren Bereich des an einer Schiene aufgehängten Leitungswagens erstreckt sich diese senkrecht zur Verfahrrichtung. In Form eines halbkreisförmigen Blechs kann diese jeweils seitlich des Fahrgestells mit Leitungen beladen werden. Vorteilhafterweise weisen die Leitungstragen jeweils Klemmleisten auf, um die aufliegenden Leitungen in ihrer Lage lösbar zu fixieren. In order to achieve a proper use of the festoon carriage, it is provided that the chassis has a line stretcher. In the lower area of the festooned on a rail festoon this extends perpendicular to the direction of travel. In the form of a semicircular sheet, this can be loaded in each case laterally of the chassis with lines. Advantageously, the cable carriers each have terminal strips to releasably fix the overlying cables in their position.
Der Leitungswagen ist zum Verfahren an einer im Querschnitt Doppel-T- förmigen Schiene vorgesehen. Dieser einfache und standardisierte Querschnitt ermöglicht die Bereitstellung eines kostengünstigen Schienensystems, an dem der Leitungswagen hängend verfahren werden kann. The cable trolley is provided for moving on a cross-sectionally double-T-shaped rail. This simple and standardized cross-section makes it possible to provide a cost-effective rail system on which the cable trolley can be suspended.
Für eine kompakte Bauform des Leitungswagens ist es von Vorteil, wenn die Laufrollen auf einem Untergurt der Schiene abrollen. Ferner weist der Leitungswagen Führungsrollen auf, deren jeweilige Drehachse in Verfahrrichtung des Leitungswagens senkrecht zu einer Drehachse der Laufrollen angeordnet ist. Auf dieser Weise können sich die Führungsrollen jeweils an einem Steg der Doppel-T-förmigen Schiene abstützen, um das Kippen sowie mögliche hin und her Bewegungen durch Schaukeln des Leitungswagens aufzunehmen. Durch diese Anordnung wird der Leitungswagen in seiner Verfahrrichtung stabil gehalten. For a compact design of the festooned carriage, it is advantageous if the rollers roll on a lower flange of the rail. Furthermore, the cable trolley on guide rollers whose respective axis of rotation is arranged in the direction of travel of the festooned carriage perpendicular to a rotational axis of the rollers. In this way, the guide rollers can each be supported on a web of the double-T-shaped rail to accommodate the tilting and possible reciprocating movements by rocking the festoon carriage. By this arrangement, the cable trolley is kept stable in its travel direction.
Für eine spielfreie und sichere Führung des Leitungswagens entlang der Schiene weist dieser Gegenlaufrollen auf, die zum Abrollen auf der den Laufrollen gegenüberliegenden Seite des Untergurts vorgesehen sind. Hierdurch wird der Untergurt von beiden Seiten umklammert, wodurch sich eine stabile Führung des Leitungswagens ergibt. For a backlash-free and secure guidance of the festoon carriage along the rail has this counter-rollers, which are provided for rolling on the opposite side of the rollers of the lower belt. As a result, the lower flange is clasped from both sides, resulting in a stable guidance of the festoon carriage.
Der erfindungsgemäße Leitungswagen bietet dank des Einsatzes von Zahnradgetrieben größtmögliche Wartungsfreiheit. Durch die kompakte Bauform ist dieser gegenüber dem üblichen Einsatz von Riemenantrieben mit geringerem Fertigungs- und Platzaufwand behaftet. Durch die Aufteilung der notwendigen Antriebsleistung auf zwei Antriebsmotoren ergibt sich insgesamt ein sicheres und zuverlässiges System, welches sich auch noch im Falle des Ausfalls eines Motors aus eigener Kraft verfahren lässt. Durch die gekapselte Bauart ist der Laufwagen insgesamt witterungsunabhängig und insbesondere auch in Bereichen mit erhöhten Anforderungen, beispielsweise durch Staub oder Temperaturbelastung, besonders geeignet. Thanks to the use of gear drives, the cable trolley according to the invention offers the greatest possible freedom from maintenance. Due to the compact design this is subject to the usual use of belt drives with less manufacturing and space requirements. By dividing the necessary drive power on two drive motors results in total a safe and reliable system, which can be moved even in the event of failure of an engine on its own. The encapsulated design of the carriage is totally independent of weather conditions and especially in areas with increased requirements, for example by dust or temperature stress, particularly suitable.
Die Erfindung ist nachfolgend anhand eines in den Zeichnungen schematisch dargestellten Ausführungsbeispiels näher beschrieben. Es zeigt: The invention is described below with reference to an embodiment schematically illustrated in the drawings. It shows:

Leitungswagen. Figur 1 zeigt einen Leitungswagen 1 , welcher an einer Schiene 2 hängend in eine Verfahrrichtung Z richtungsgebunden beweglich angeordnet ist. Der Leitungswagen 1 weist hierbei ein Fahrgestell 3 auf, welches im Wesentlichen aus zwei jeweils längsseits der Schiene 2 angeordneten Blechen besteht, die an ihren jeweiligen Enden zur von der Schiene 2 wegweisenden Seite rechtwinklig abgewinkelt und unterhalb der Schiene 2 miteinander verbunden sind. Festoon. Figure 1 shows a cable trolley 1, which is arranged on a rail 2 hanging in a direction of travel Z directionally movable. The cable trolley 1 in this case has a chassis 3, which consists essentially of two plates arranged respectively alongside the rail 2, which are bent at right angles at their respective ends to the side facing away from the rail 2 and are connected to one another below the rail 2.
Die seitlichen Bleche des Fahrgestells 3 weisen zwischen ihren abgewinkelten Enden jeweils einen Ausschnitt 4 auf, in den ein Antriebsmotor 5 mit seinem Gehäuse teilweise hineinragt. Der Antriebsmotor 5 ist hierbei mit seiner Rotationsachse RA parallel zur Verfahrrichtung Z des Leitungswagens 1 ausgerichtet. Der Antriebsmotor 5 beinhaltet zwei, hier nicht näher dargestellte, Antriebsenden 6, welche jeweils über ein Zahnradgetriebe 7 mit den abgewinkelten Enden der Seiten des Fahrgestells 3 verbunden sind. Diese Verbindung ist über lösbare Verbindungsmittel ausgeführt und dient der Befestigung des jeweiligen Zahnradgetriebes 7 an dem Fahrgestell 3. Bei dem jeweiligen Zahnradgetriebe 7 handelt es sich jeweils um ein Winkelgetriebe, welches das zu beiden Seiten des Antriebsmotors 5 erzeugte Drehmoment um die Rotationsachse RA auf eine rechtwinklig dazu verlaufende Drehachse X umlenkt, an deren zu der Schiene 2 weisenden Ende, in Figur 1 nicht näher dargestellte, Laufrollen 8 angeordnet sind, die auf einem Untergurt 9 der Schiene 2 abrollen. Pro Längsseite der Schiene 2 befinden sich somit jeweils zwei Laufrollen 8, die jeweils über ein Zahnradgetriebe 7 mit den beiden Antriebsenden 6 des Antriebsmotors 5 mechanisch verbunden sind, so dass der Leitungswagen 1 über insgesamt vier Laufrollen 8 an dem Untergurt 9 der Schiene 2 in Verfahrrichtung Z beweglich aufgehängt ist. The lateral plates of the chassis 3 have between their angled ends in each case a cutout 4, in which a drive motor 5 partially protrudes with its housing. The drive motor 5 is in this case aligned with its axis of rotation RA parallel to the travel direction Z of the festoon carriage 1. The drive motor 5 includes two, not shown here, drive ends 6, which are each connected via a gear transmission 7 with the angled ends of the sides of the chassis 3. This connection is made via releasable connecting means and serves to attach the respective gear transmission 7 to the chassis 3. The respective gear transmission 7 is in each case an angular gear, which generates the torque generated on both sides of the drive motor 5 about the axis of rotation RA to a right angle for this purpose rotates pivot axis X, at whose pointing to the rail 2 end, not shown in Figure 1, rollers 8 are arranged, which roll on a lower flange 9 of the rail 2. Per each longitudinal side of the rail 2 are thus two rollers 8, which are mechanically connected in each case via a gear transmission 7 with the two drive ends 6 of the drive motor 5, so that the cable trolley 1 via a total of four rollers 8 on the lower flange 9 of the rail 2 in the direction of travel Z is movably suspended.
Das Fahrgestell 3 des Leitungswagens 1 weist auf beiden Längsseiten an seinen beiden oberen Enden jeweils eine abgebogene Lasche auf. Die Laschen weisen zur Schiene 2. Sie verlaufen parallel zum Untergurt 9 der Schiene 2. An den Laschen sind jeweils Führungsrollen 10 um eine Drehachse Y drehbar gelagert angeordnet. Die Führungsrollen 10 stehen umfangsseitig mit einem Steg der im Querschnitt Doppel-T-förmigen Schiene 2 in Kontakt, wobei deren jeweilige Rotationsebene parallel zum Untergurt 9 der Schiene 2 verläuft. Insgesamt weist das Fahrgestell 3 des Leitungswagens 1 somit vier Führungsrollen 10 auf, welche einer Kippung des Leitungswagens 1 entgegenwirken. The chassis 3 of the festoon carriage 1 has on both longitudinal sides at its two upper ends in each case a bent tab. The tabs point to the rail 2. They run parallel to the bottom flange 9 of the rail 2. At the tabs guide rollers 10 are arranged rotatably about a rotation axis Y respectively. The guide rollers 10 are circumferentially with a web of cross-sectionally double-T-shaped rail 2 in contact, wherein the respective rotation plane is parallel to the lower flange 9 of the rail 2. Overall, the chassis 3 of the festoon carriage 1 thus four guide rollers 10, which counteract a tilting of the festoon carriage 1.
Zwischen den beiden Seitenblechen des Fahrgestells 3 ist ein sich in der Ebene des Stegs der Schiene 2 erstreckendes Konturblech 1 1 angeordnet, welches an seinem unteren Ende eine rechtwinklig dazu verlaufende Leitungstrage 12 aufweist. Die Leitungstrage 12 wird hierbei aus einem im Querschnitt halbkreisförmig gebogenen Blech gebildet, welches sich zu beiden Seiten des Konturblechs 11 senkrecht zur Verfahrrichtung Z des Leitungswagens 1 erstreckt. Between the two side plates of the chassis 3 in the plane of the web of the rail 2 extending contour sheet 1 1 is arranged, which has at its lower end a perpendicular thereto extending line support 12. In this case, the conductor carrier 12 is formed from a semicircularly curved metal sheet in cross section, which extends perpendicular to the direction of travel Z of the festooned carriage 1 on both sides of the contouring plate 11.
Umfangsseitig weist die Leitungstrage 12 zwei sich zur Drehachse X der Laufrollen 8 parallel erstreckende Klemmleisten 13 auf, die jeweils zu einer vom Zentrum der halbkreisförmigen Leitungstrage 12 aus verlaufenden Hochachse zu beiden Seiten jeweils um 15 Grad versetzt angeordnet sind. On the circumference, the line support 12 has two clamping bars 13 extending in parallel to the axis of rotation X of the rollers 8, which are each arranged offset by 15 degrees on both sides to a vertical axis extending from the center of the semicircular conductor carrier 12.
Das Konturblech 1 1 weist an einer Seite seiner in Verfahrrichtung Z verlaufenden maximalen Breite einen Anschlagpuffer 14 auf, welcher sich parallel zur Rotationsachse RA erstreckt und aus einem elastischen Material besteht. Unterhalb der Ebene des Anschlagspuffers 14 sind an beiden Enden des Konturblechs 1 1 jeweils Zugösen 15 angeordnet, die im Wesentlichen hufeisenförmig ausgebildet sind und jeweils über einen parallel zur Drehachse X verlaufenden Achsbolzen in einer Ebene beweglich mit dem Konturblech 11 des Leitungswagens 1 verbunden sind. The contour sheet 1 1 has on one side of its extending in the direction Z maximum width a stop buffer 14 which extends parallel to the axis of rotation RA and consists of an elastic material. Below the plane of the stop buffer 14 1 draw eyes 15 are arranged at both ends of the contour sheet 1, which are formed substantially horseshoe-shaped and are each connected via a parallel to the axis of rotation X extending axle in a plane movable with the contour sheet 11 of the festoon carriage 1.
Figur 2 zeigt den bereits in Figur 1 dargestellten Leitungswagen 1 in einer Frontansicht mit Blick auf die Anschlagpuffer 14. Gut zu erkennen ist hierbei die Doppel-T-förmige Querschnittsform der Schiene 2. In dieser Ansicht ist erkennbar, dass der Leitungswagen 1 ebenfalls mit der Schiene 2 in Kontakt stehende Gegenlaufrollen 16 aufweist, welche umfangsseitig auf der den Laufrollen 8 gegenüberliegenden Seite des Untergurts 9 abrollen und parallel zur Rotationsebene der Laufrollen 8 angeordnet sind. Die Gegenlaufrollen 16 sind auf einer, hier nicht näher dargestellten, Achse drehbar gelagert, welche sich parallel zur Drehachse X der Laufrollen 8 zwischen den beiden Seitenblechen des Fahrgestells 3 erstreckt. Als jeweiliges Gegenlager zu den Laufrollen 8 weisen diese ebenfalls eine Stückzahl von Vier auf, um den Leitungswagen 1 präzise entlang der Schiene 2 verfahren zu können. Figure 2 shows the cable trolley 1 already shown in Figure 1 in a front view overlooking the stop buffer 14. Good to see here is the double-T-shaped cross-sectional shape of the rail 2. In this view can be seen that the cable trolley 1 also with the Rail 2 in contact mating rollers 16 which circumferentially roll on the rollers 8 opposite side of the lower belt 9 and parallel are arranged to the plane of rotation of the rollers 8. The counter-rotating rollers 16 are rotatably mounted on an axis, not shown here, which extends parallel to the axis of rotation X of the rollers 8 between the two side plates of the chassis 3. As a respective abutment to the rollers 8, these also have a number of four in order to move the cable trolley 1 precisely along the rail 2 can.
Figur 3 zeigt eine Kabelwagenanlage in Seitenansicht, welche neben dem Leitungswagen 1 weitere entlang der Schiene 2 angeordnete Leitungswagen aufweist, die ebenfalls angetrieben oder nicht angetrieben sind. Die Verteilung von angetriebenen und nicht angetriebenen Leitungswagen ist individuell und an die entsprechenden Erfordernisse angepasst. Beispielsweise können einem angetriebenen Leitungswagen zwei nicht angetriebene Leitungswagen nachlaufen, denen wiederum ein angetriebener folgt. Zwischen den einzelnen Leitungswagen befindet sich jeweils ein elastisches Zugelement 17 in Form eines Gummiseils sowie ein weiteres Zugelement 18, welches als Stahlseil ausgebildet ist. Die Zugelemente 17, 18 sind jeweils mit den Zugösen 15 verbunden. Ebenfalls dazwischen befinden sich Leitungen 19, welche mit einem größeren Durchhang auf der jeweiligen Leitungstrage 12 aufliegen. Vor Kopf dieser Anordnung befindet sich eine Krankatze, die mit den zum Verbraucher führenden Leitungen 19 verbunden ist. Die Leitungen 19 werden hierbei in durchhängenden Schlaufen jeweils auf die Leitungstrage 12 der Leitungswagen aufgelegt und über Klemmleisten 13 in ihrer Lage fixiert. Figure 3 shows a cable car system in side view, which has next to the cable trolley 1 further along the rail 2 arranged cable trolleys, which are also driven or not driven. The distribution of driven and non-driven cable trolleys is individual and adapted to the corresponding requirements. For example, a driven cable trolley run after two non-driven cable trolleys, which in turn follows a driven. Between the individual cable trolleys is in each case an elastic tension element 17 in the form of a rubber rope and a further tension element 18, which is designed as a steel cable. The tension elements 17, 18 are each connected to the drawbar eyes 15. Also in between are lines 19, which rest with a larger sag on the respective line support 12. In front of the head of this arrangement is a trolley, which is connected to the lines leading to the consumer 19. The lines 19 are in this case placed in sagging loops respectively on the line stretcher 12 of the trolley and fixed by terminal strips 13 in position.
Ein Antriebsmotor 5 des Leitungswagens 1 wird hierbei über ein Fahrsignal der Krankatze angesteuert, wobei die Drehzahl des Antriebsmotors 5 über einen Frequenzumrichter entsprechend angepasst wird. Das entstehende Drehmoment wird über beidseitige Antriebsenden 6 des Antriebsmotors 5 jeweils auf ein Zahnradgetriebe 7 übertragen und an mit dem Zahnradgetriebe 7 verbundenen Laufrollen 8 in einem entsprechenden Übersetzungsverhältnis weitergegeben. Die nunmehr rotierenden Laufrollen 8 rollen auf dem Untergurt 9 der Schiene 2 umfangsseitig ab, wobei deren jeweilige Drehrichtung eine Verfahrrichtung Z des Leitungswagens 1 bewirkt. Durch das auseinanderfahren sowie zusammenfahren der miteinander verbundenen Leitungswagen 1 wird eine notwendige Energie- und Datenübertragung des beweglichen Verbrauchers sichergestellt. A drive motor 5 of the festoon carriage 1 is in this case driven by a travel signal of the crane trolley, wherein the rotational speed of the drive motor 5 is adjusted accordingly via a frequency converter. The resulting torque is transmitted via two-sided drive ends 6 of the drive motor 5 each to a gear transmission 7 and passed on connected to the gear transmission 7 rollers 8 in a corresponding gear ratio. The now rotating rollers 8 roll on the lower flange 9 of the rail 2 circumferentially, wherein the respective direction of rotation causes a travel direction Z of the festoon carriage 1. By diverge and moving together the interconnected cable trolley 1, a necessary energy and data transmission of the mobile consumer is ensured.
