Abstract

Die Erfindung betrifft einen Schlingenwagenantrieb, bei dem der Schlingenwagen das zu führende Band hält und durch eine mit einem Antrieb verbundene Umlenkrollen aufweisende Seilanordnung in Längsrichtung des Bandes vor- und zurückbewegbar und dabei gleichzeitig gefesselt ist und wobei sowohl das Zug- wie auch das Fesselseil am vom Antrieb abgewandten Ende verankert sind, und zwar das Zugseil an einem in der Länge verstellbaren Festpunkt und das Festseil an einem Spannzylinder. Um einen Schlingenantrieb zu schaffen, der sich durch einen vereinfachten Aufbau auszeichnet und bei dem dennoch der Schlingenwagen gefesselt geführt werden kann, wird vorgeschlagen, daß dem Antrieb eine Seilbahnmaschine zugeordnet ist, die zwei im Abstand angeordnete Seilumlenkräder (1, 2) aufweist, von denen ein Rad (1) gegenüber dem anderen Rad (2) derart schräggestellt ist, daß das Seil (3) durch das schräggestellte Rad (1) im Scheitelbereich des anderen Rades (2) in unterschiedliche Nuten aufgelegt bzw. abgezogen wird und daß durch die Seilbahnmaschine sowohl das Zug- wie auch das Fesselseil geführt sind.The invention relates to a sling car drive, in which the sling car holds the tape to be guided and can be moved back and forth in the longitudinal direction of the tape by means of a cable arrangement connected to a drive pulley and is simultaneously tied up, and both the traction and the tether rope on Drive anchored end are anchored, namely the pull rope at a length-adjustable fixed point and the fixed rope on a tension cylinder. In order to create a loop drive which is characterized by a simplified structure and in which the loop carriage can nevertheless be guided in a tied manner, it is proposed that the drive be assigned a cable car machine which has two cable deflection wheels (1, 2) arranged at a distance, one of which one wheel (1) is inclined relative to the other wheel (2) in such a way that the cable (3) is placed or pulled off in different grooves in the apex area of the other wheel (2) by the inclined wheel (1) and that by the cable car machine both the traction and the tether rope are guided.

Description

Aus der Praxis sind Schlingenwagenantriebe bekannt, bei denen der das Band führende Wagen über eine Seilanordnung bewegt wird. Das hierzu benutzte Seil ist einerseits an einem Festpunkt verankert, wird dann über Umlenkrollen am Seilwagen zu einer Seilwinde zurückgeführt und durch Drehung dieser Seilwinde auf- bzw. abgespult.Loop car drives are known in practice, in which the car guiding the belt is moved via a cable arrangement. The rope used for this is anchored on the one hand at a fixed point, is then returned to the cable winch via deflection rollers on the cable wagon, and is wound or unwound by rotating this cable winch.

Nachteilig ist hierbei ein Seilversatz, der sich durch das Aufspulen bzw. Abspulen auf die Seilwinde ergibt, wobei hier ein bestimmter Auflaufwinkel eingehalten werden muß. Ein weiterer wesentlicher Nachteil ist darin zu sehen, daß dann, wenn der Wagen schnell in Richtung Seilwinde gezogen wird und bspw. das Band plötzlich reißt, der Wagen ungebremst gegen die Pufferanordnung fährt und es dabei zu Zerstörungen am Wagen oder der Anlage selbst kommen kann. Um diesen Nachteil zu vermeiden, ist es bereits bekannt, den Wagen über ein eigentliches Haupt- oder Zugseil zu führen und andererseits über ein Fesselseil zu halten. Das Haupt- oder Zugseil wird über Umlenkrollen an der vom Band abgewandten Seite des Schlingenwagens geführt, während das Fesselseil über Rollen auf der Bandseite des Wagens umgelenkt und über eine weitere Umlenkrolle ebenfalls zur Seilwinde geführt wird. Der Vorteil dieser Ausführung ist, daß durch die Kombination Zugseil/Fesselseil der Wagen sehr genau führbar ist, und zwar in jeder Richtung, und er kann auf diese Weise auch zu jedem Punkt gefahren werden. Nachteilig ist aber, daß auch hierbei eine Seilwinde verwendet wird, die zum Aufwickeln des Haupt- oder Zugseiles wie auch des Fesselseiles notwendig ist.The disadvantage here is a cable offset, which results from the winding or unwinding on the cable winch, a certain run-up angle having to be observed here. Another major disadvantage is that if the car is pulled quickly towards the winch and, for example, the belt suddenly breaks, the car runs against the buffer arrangement unchecked and damage to the car or the system itself can occur. In order to avoid this disadvantage, it is already known to guide the carriage over an actual main or traction rope and, on the other hand, to hold it over a tether rope. The main or traction rope is guided over deflection rollers on the side of the sling wagon facing away from the belt, while the anchoring rope is deflected over rollers on the hinge side of the carriage and is also guided to the cable winch via a further deflection roller. The advantage of this design is that the wagon can be guided very precisely by the combination of the pull rope / anchoring rope, in any direction, and it can also be driven to any point in this way. The disadvantage, however, is that a winch is used here as well, which is necessary for winding up the main or pull rope as well as the fetter rope.

Der Erfindung liegt die Aufgabe zugrunde, einen Schlingenwagenantrieb zu schaffen, der sich durch einen vereinfachten Aufbau auszeichnet und bei dem dennoch der Schlingenwagen gefesselt geführt werden kann.The invention has for its object to provide a sling car drive, which is characterized by a simplified structure and in which the Sling car can be guided tied up.

Gelöst wird diese Aufgabe mit den Merkmalen im Patentanspruch.This problem is solved with the features in the claim.

Der besondere Vorteil der erfindungsgemäßen Lösung ist in der Anwendung einer Seilbahnmaschine zu sehen. Bei diesem System wird das Seil nicht mehr aufgewickelt, sondern der Wagen wird durch die Seilbahnmaschine über Reibschluß verfahren. Die bei einem solchen Reibschlußantrieb erforderliche Gegenkraft wird über das gleiche Seil (Fesselseil), das an der anderen Seite des Wagens befestigt ist, durch einen Spannzylinder an der Umlenkrolle oder am Festpunkt, der dem Antrieb gegenüberliegt, erzeugt. Damit ist der Wagen, wie beim aus der Praxis bekannten Ausführungsbeispiel, gefesselt, kann dennoch zu jedem beliebigen Punkt sicher geführt werden und vermeidet eine Seilwinde, so daß auch Seilablenkungen, die die Funktion der Seilwinde beeinträchtigen könnten, vermieden werden. Schließlich ist noch wesentlich, daß dieses Antriebssystem konstruktiv einfacher und damit preisgünstiger zu erstellen ist.The particular advantage of the solution according to the invention can be seen in the use of a cable car machine. With this system, the rope is no longer wound up, but the car is moved by the cable car machine via frictional engagement. The counterforce required in such a friction drive is generated via the same rope (tether rope), which is attached to the other side of the car, by a tensioning cylinder on the deflection roller or at the fixed point, which is opposite the drive. Thus, the trolley, as in the embodiment known from practice, is tied up, can nevertheless be guided safely to any point and avoids a cable winch, so that cable deflections which could impair the function of the cable winch are avoided. Finally, it is essential that this drive system is structurally simpler and therefore cheaper to produce.

Die Erfindung soll nachfolgend anhand der Zeichnungen erläutert werden. Dabei zeigt die

  • Fig. l die grundsätzliche Seilführung zwischen Schlingenwagen und Seilbahnmaschine,
  • Fig. 2 und
  • Fig. 3 eine schematische Darstellung der Seilbahnmaschine und
  • Fig. 4 einen Schnitt gemäß der Linie A-A in Fig. 3
The invention will be explained below with reference to the drawings. The shows
  • 1 shows the basic cable routing between loop car and cable car machine,
  • Fig. 2 and
  • Fig. 3 is a schematic representation of the cable car machine and
  • 4 shows a section along line AA in FIG. 3

In der Figur 1 ist schematisch die grundsätzliche Seilführung zwischen Schlingenwagen 5 und Seilbahnmaschine 11 dargestellt. Der Schlingenwagen 5 hält das nicht dargestellte Band, wobei hier lediglich durch einen Pfeil der Bandzug angedeutet ist. Dieser Schlingenwagen ist mit Umlenkrollen 4 versehen. Die Umlenkrollen 4 führen einerseits das Fesselseil 14, das über den Pneumatikzylinder 6 abgestützt wird und das im gezeigten Beispiel über die weiteren Umlenkrollen 8 und 9 sowie die Umlenkrolle 12 mit der Seilbahnmaschine verbunden ist. Das Zugseil 15 läuft ebenfalls über Umlenkrollen 4 am Schlingenwagen und ist am Festpunkt 7 gehalten. Bei dem gezeigten Beispiel läuft dieses Zugseil 15 über die Rolle 13 in die Seilbahnmaschine ein. Die Seilbahnmaschine selbst besitzt außer den Führungsrollen 12 und 13 eine Umlenkrolle 1 sowie eine Treibrolle 2. Die Umlenkrolle 1 ist gegenüber der Treibrolle, wie die Figur 4 zeigt, schräggestellt, so daß das Auflegen bzw. Abziehen auf den Scheitelbereich bzw. aus dem Scheitelbereich der Treibrolle 2 in verschiedenen Nuten erfolgt. Durch diesen an sich bekannten Reibschlußantrieb in der Seilbahnmaschine kann auf eine übliche Seilwinde, wie sie bei bisherigen Anlagen notwendig war, verzichtet werden und dennoch wird gewährleistet, daß der Schlingenwagen durch das Zugseil bzw. das Festseil ständig gehalten ist.In Figure 1 , the basic cable routing between loop car 5 and cable car machine 11 is shown schematically. The sling carriage 5 holds the band, not shown, the band tension being indicated only by an arrow. This loop carriage is provided with deflection rollers 4 . The deflection rollers 4 on the one hand guide the rope 14 which is supported by the pneumatic cylinder 6 and which in the example shown is connected to the cable car machine via the further deflection rollers 8 and 9 and the deflection roller 12. The pull rope 15 also runs over pulleys 4 on the sling car and is held at fixed point 7 . In the example shown, this pull rope 15 runs over the roller 13 into the cable car machine. In addition to the guide rollers 12 and 13, the cable car machine itself has a deflection roller 1 and a drive roller 2. The deflection roller 1 is inclined relative to the drive roller, as shown in FIG. 4, so that the application or removal from the apex area or . from the apex of the drive roller 2 in different grooves. Due to this known friction drive in the cable car machine, a conventional cable winch, as was necessary in previous systems, can be dispensed with and nevertheless it is ensured that the sling wagon is constantly held by the traction cable or the fixed cable.

Es sei abschließend noch erwähnt, daß aus Gründen des besseren Verständnisses von dem Fesselseil 14 und dem Zugseil 15 gesprochen wurde. Im eigentlichen Sinne handelt es sich um ein einziges Seil, dessen einer Abschnitt als Fesselseil und dessen anderer Abschnitt als Zugseil wirkt. In der Seilbahnmaschine gehen beide Seilabschnitte ineinander über.It should finally be mentioned that, for reasons of better understanding, the rope 14 and the traction rope 15 were mentioned. In the true sense, it is a single rope, one section of which acts as a tether rope and the other section as a traction rope. In the cable car machine, both cable sections merge.
