Abstract

For increasing the friction force of a drive wheel (3) an additional force is provided, acting on the underside of a running rail (2), and rolling with the aid of a spring. The auxiliary wheels are pressure rollers (7) arranged against the underside (5) of the running rail. The pressure rollers have half the dia. of the drive wheel. A distributor shaft (6) driving the pressure rollers has the same speed as the drive wheel. It is driven with the aid of a chain (8) from the drive wheel and carries a gearwheel (12) which engages in gearwheels (13) fixed on the shafts of the pressure rollers. The pressure rollers are so arranged in a device (10) that their pivot centre point coincides with that of the distributor shaft.

Description

Die Erfindung betrifft eine Elektrohängebahn zum Transportieren von Lasten mit einem angetriebenen Fahrwerk, bestehend aus einem auf einer Laufschiene verfahrbaren Antriebsrad und zwei Hilfsrädern, wobei zur Erhöhung der Reibungskraft des Antriebsrades eine auf die Unterseite der Laufschiene wirkende, rollend mit Hilfe einer Feder aufgebrachte Zusatzkraft vorgesehen ist.The invention relates to an electric monorail system for transporting loads with a driven undercarriage, consisting of a drive wheel which can be moved on a running rail and two auxiliary wheels, an additional force acting on the underside of the running rail, which is applied in a rolling manner by means of a spring, being provided to increase the frictional force of the drive wheel .

Bekanntlich sind dem Transportieren von Lasten längs einer Laufschiene in Steigungs- und Gefällebereichen sowie im Ziehen von Lasten am Boden mittels einer Elektrohängebahn Grenzen gesetzt, da das Transportieren und Ziehen der Lasten über Reibschluß zwischen dem Antriebsrad und der Laufschiene erfolgt und der Reibschluß oft dafür nicht ausreicht. In der Literatur sind eine Reihe von Vorschlägen gemacht, um den Reibschluß zwischen Antriebsrad und Laufschiene zu erhöhen.As is known, there are limits to the transport of loads along a running rail in incline and downhill areas and in the pulling of loads on the ground by means of an electric monorail conveyor, since the transporting and pulling of the loads takes place via frictional engagement between the drive wheel and the running rail and the frictional engagement is often not sufficient for this . A number of proposals have been made in the literature to increase the frictional connection between the drive wheel and the running rail.

So ist beispielsweise aus der Druckschrift DE 42 06 493 A 1 eine Elektrohängebahn zum Transportieren und Ziehen von Lasten bekannt, bei dem ein Antriebsrad vorhanden ist, dem zummindest zwei nicht angetriebene Hilfsräder zugeordnet sind, die mit einer parallel zur Laufschiene angeordneten Gegendruckschiene wechselwirken. Diese Elektrohängebahn ist für viele Fälle gut geeignet, sie setzt aber eben das Vorhandensein einer Gegendruckschiene voraus, was in manchen Fällen nicht realisierbar ist.For example, DE 42 06 493 A 1 discloses an electric monorail conveyor for transporting and pulling loads, in which there is a drive wheel to which at least two non-driven auxiliary wheels are assigned, which interact with a counter-pressure rail arranged parallel to the running rail. This monorail conveyor is well suited for many cases, but it requires the presence of a counter pressure rail, which in some cases is not feasible.

Aus der Druckschrift DE 42 05 858 A1 sind verschiedene Systeme bekannt, um die Reibungskraft des Antriebsrades einer Elektrohängebahn zu erhöhen. So ist eine Anordnung beschrieben, wo eine Zusatzkraft mit Hilfe einer Druckrolle und einer Feder auf die Unterseite der Fahrschiene aufgebracht wird. Diese eine mit Hilfe einer Feder gegen die Fahrschiene gedrückte Druckrolle reicht für viele Einsatzzwecke nicht aus, um die notwendige Reibkraft zu erzeugen. Aus dieser Druckschrift ist weiterhin eine Anordnung bekannt, bei der zwei Hilfsräder auf die Unterseite der Fahrschiene wirken, wobei das Erhöhen der Reibungskraft durch Verkanten des Systems erzeugt wird. Bei Elektrohängebahnen mit diesem Verkanten rollen beispielsweise die Führungsrollen in Steigungs- und Gefällstrecken nicht normal ab.Various systems are known from publication DE 42 05 858 A1 in order to increase the frictional force of the drive wheel of an electric monorail conveyor. An arrangement is thus described where an additional force is applied to the underside of the travel rail with the aid of a pressure roller and a spring. This pressure roller, which is pressed against the rail by means of a spring, is not sufficient for many purposes in order to generate the necessary frictional force. From this document an arrangement is also known in which two auxiliary wheels act on the underside of the rail, the increase in the frictional force being generated by tilting the system. In the case of electric monorails with this tilting, for example, the guide rollers do not roll normally on inclines and descents.

Der Erfindung liegt die Aufgabe zugrunde, für Elektrohängebahnen der eingangs näher bezeichneten Art eine konstruktive Lösung vorzuschlagen, mit der ein Fahrwerk für Elektrohängebahnen geschaffen wird, das für alle vorkommenden Betriebsfälle einen großen Reibschluß zur Laufschiene aufweist.The invention has for its object to propose a constructive solution for electric monorails of the type specified in the introduction, with which a trolley for electric monorails is created which has a large frictional connection to the running rail for all occurring operating cases.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Hilfsräder gegen die Unterseite der Laufschiene angeordnete Andruckrollen sind, daß die Andruckrollen den halben Durchmesser des Antriebsrades aufweisen und daß eine die Andruckrollen antreibende Verteilerwelle die gleiche Drehzahl wie das Antriebsrad aufweist.This object is achieved in that the auxiliary wheels are pressure rollers arranged against the underside of the running rail, that the pressure rollers have half the diameter of the drive wheel and that a distributor shaft driving the pressure rollers has the same speed as the drive wheel.

Gemäß einer vorteilhaften Ausbildung der Erfindung ist vorgesehen, daß eine Verteilerwelle mit Hilfe einer Kette von dem Antriebsrad angetrieben wird, daß die Verteilerwelle ein Zahnrad trägt, das in Zahnräder eingreift, die auf den Wellen der Andruckrollen befestigt sind.According to an advantageous embodiment of the invention it is provided that a distributor shaft is driven by means of a chain from the drive wheel, that the distributor shaft carries a gearwheel which engages in gearwheels which are fastened on the shafts of the pressure rollers.

Eine weitere Ausbildung der Erfindung besteht darin, daß die Andruckrollen so in einer Vorrichtung angeordnet sind, daß ihr Schwenkmittelpunkt denjenigen der Verteilerwelle entspricht.Another embodiment of the invention is that the pressure rollers are arranged in a device so that their pivot center corresponds to that of the distributor shaft.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß das Fahrwerk einer Elektrohängebahn sich automatisch unter hohem Reibschluß mit der Laufschiene "verkrallt", so daß ohne weiteres damit auch Steigungen oder Gefällstrecken befahren werden können.The advantages achieved by the invention consist in particular in the fact that the trolley of an electric monorail automatically "claws" under high frictional engagement with the running rail, so that it can also be used to drive up and down gradients.

Die Erfindung wird anhand der Zeichnungen näher beschrieben.The invention is described in more detail with reference to the drawings.

Es zeigt

Fig. 1 und Fig. 2
schematisch die wesentlichen Teile der neuen Elektrohängebahn in zwei Ansichten,
Fig. 3 und Fig. 4
prinzipiell dieselbe Elektrohängebahn wie in den Fig. 1 und 2 dargestellt, aber für andere Aufgaben geeignet.
It shows
1 and 2
schematically the essential parts of the new monorail system in two views,
3 and 4
basically the same monorail conveyor as shown in FIGS. 1 and 2, but suitable for other tasks.

Die Fig. 1 zeigt eine Elektrohängebahn in Vorderansicht und Fig. 2 diese Elektrohängebahn in Seitenansicht. Das Fahrwerk 1 der Elektrohängebahn ist entlang der Laufschiene 2 bewegbar, wobei das Antriebsrad 3 des Fahrwerks 1 sich auf der Laufschiene 2 abstützt. Mit 4 sind Führungsrollen bezeichnet, die zur seitlichen Führung des Fahrwerks 1 an der Laufschiene 2, wie in den Fig. 1 und 2 dargestellt, dienen. Mit Hilfe einer Verteilerwelle 6 werden auf der Unterseite 5 der Laufschiene 2 angeordnete Andruckrollen 7 angetrieben. Die Verteilerwelle 6 selbst wird mit Hilfe einer Kette 8 angetrieben, die die Verteilerwelle 6 und das Antriebsrad 3 miteinander verbinden. Das Antriebsrad 3 wiederum wird über die Welle 9 angetrieben. Die Andruckrollen 7 sind in einer Vorrichtung 10 drehbar angeordnet, die Druckfedern 11 aufweist, mit deren Hilfe die Andruckrollen 7 ständig in gutem Reibschluß zu der Unterseite 5 der Laufschiene 2 gehalten werden. So ergibt sich ein Fahrwerk 1, das ständig, also auch bei Steigungen oder Gefälle, in optimalem Reibschluß zur Ober- und Unterseite der Laufschiene 2 ist.Fig. 1 shows an electric monorail in front view and Fig. 2 this electric monorail in side view. The undercarriage 1 of the electric monorail conveyor can be moved along the running rail 2, the drive wheel 3 of the undercarriage 1 being supported on the running rail 2. 4 with guide rollers are designated, which serve for lateral guidance of the chassis 1 on the running rail 2, as shown in FIGS. 1 and 2. With the aid of a distributor shaft 6, pressure rollers 7 arranged on the underside 5 of the running rail 2 are driven. The distributor shaft 6 itself is driven by means of a chain 8, which connect the distributor shaft 6 and the drive wheel 3 to one another. The drive wheel 3 in turn is driven by the shaft 9. The pressure rollers 7 are rotatably arranged in a device 10 which has compression springs 11, with the aid of which the pressure rollers 7 are constantly held in good frictional engagement with the underside 5 of the running rail 2. This results in a chassis 1 which is in constant frictional contact with the top and bottom of the running rail 2 at all times, that is to say even on inclines or descents.

Bei der erfindungsgemäßen Anordnung ist es wichtig, daß die Andruckrollen 7 den halben Durchmesser des Antriebsrads 3 aufweisen, weil die über die Kette 8 angetriebene Verteilerwelle 6 die gleiche Drehzahl wie das Antriebsrad 3 hat. Durch diese Ausbildung ergibt sich, daß die Andruckrollen 7 die doppelte Drehzahl wie das Antriebsrad 3 haben, so daß das Fahrwerk 1 auf der Ober- und Unterseite der Laufschiene 2 den richtigen Antrieb mit der richtigen Drehzahl aufweist.In the arrangement according to the invention, it is important that the pressure rollers 7 have half the diameter of the drive wheel 3, because the distributor shaft 6 driven by the chain 8 has the same speed as the drive wheel 3. This design results in that the pressure rollers 7 have twice the speed as the drive wheel 3, so that the chassis 1 on the top and bottom of the track 2 has the correct drive at the correct speed.

Wie aus den Fig. 1 und 2 schematisch ersichtlich ist, sitzt aufder Verteilerwelle 6 ein Zahnrad 12, welches in Zahnräder 13 eingreift, die aufden Achsen der Andruckrollen 7 befestigt sind. Das bedeutet, daß der Antrieb der Andruckrollen so verläuft, daß von dem Antriebsrad 3 über die Kette 8 die Verteilerwelle 6 und damit das Zahnrad 12 angetrieben werden und letzteres, wie gesagt, die Zahnräder 13 antreibt und damit die Andruckrollen 7. Mit den Pfeilen 14 in Fig. 1 ist angedeutet, daß die Andruckrollen 7 so in der Vorrichtung 10 angeordnet sind, daß ihr Schwenkmittelpunkt demjenigen der Verteilerwelle 6 entspricht. Dadurch ist der Achsabstand der Zahnräder 13 bei jedem Schwenkwinkel gleich.As can be seen schematically from FIGS. 1 and 2, a gearwheel 12 is seated on the distributor shaft 6, which meshes with gearwheels 13 which are fastened on the axes of the pressure rollers 7. This means that the drive of the pressure rollers runs in such a way that the distributor shaft 6 and thus the gearwheel 12 are driven by the drive wheel 3 via the chain 8 and, as said, the latter drives the gearwheels 13 and thus the pressure rollers 7. With the arrows 14 In Fig. 1 it is indicated that the pressure rollers 7 are arranged in the device 10 so that their pivot center corresponds to that of the distributor shaft 6. As a result, the center distance of the gears 13 is the same at every swivel angle.

Mit den Pfeilen 15 ist angedeutet, wie eine Last an dem Fahrwerk 1 wirken kann. Mit 17 sind schematisch die Stromabnehmer für den elektromotorischen Antrieb und die Steuerung des Fahrwerks 1 angedeutet.The arrows 15 indicate how a load on the chassis 1 can act. With 17 the pantographs for the electric motor drive and the control of the chassis 1 are indicated schematically.

In den Fig. 3 und 4 ist in Vorder- und Seitenansicht ein erfindungsgemäßes Fahrwerk 1 dargestellt, es unterscheidet sich von der Ausführung gemäß den Fig. 1 und 2 dadurch, daß die Last von dem Fahrwerk getragen wird, wie das durch den Pfeil 18 angedeutet ist. Eine solche Anordnung mit Arbeitsplattformen 19 ist quasi eine Elektroständerbahn, die auch Steigungen bzw. Gefälle befahren kann.3 and 4, a chassis 1 according to the invention is shown in front and side view, it differs from the embodiment according to FIGS. 1 and 2 in that the load is carried by the chassis, as indicated by the arrow 18 is. Such an arrangement with work platforms 19 is quasi an electric tram that can also drive up and down gradients.
