Description

Es ist eine Tragvorrichtung für Einseilhahnen bekannt, bei der der die Last tragende Balken sich auf dem Seil abstützt mittels zweier in der Seilrichtung begrenzt beweglicher Tragschuhe, in denen als Stützmittel je zwei gleichachsig zum Seil drehbar angeordnete zylindrische Rollen dienen, auf deren Mänteln schraubenförmige Hohlrillen angeordnet sind, die dem Schlage des Seiles entsprechen. Diese bekannte Einrichtung hat sich, weil durch die große Auflagefläche der spezifische Druck auf das Seil verringert wird und dieses sich, ungehindert um seine Längsachse drehen (spinnen) kann, im Sinne einer außerordentlichen Seilschonung und eines stoßfreien Aufsetzens und Abhebens der Last vorzüglich bewährt, sie befriedigt indessen nur, wenn die Neigung der Bahn eine gewisse Grenze nicht überschreitet; von einer bestimmten Bahnneigung an besteht die Gefahr, daß die auf das Seil aufgesetzte Last längs des Seiles rutscht.A support device for single-rope cocks is known in which the load-bearing device is used The beam is supported on the rope by means of two that are limited in the rope direction Carrying shoes, in which, as support means, two each rotatably arranged on the same axis as the rope Cylindrical rollers are used, on whose shells helical hollow grooves are arranged, which the lay of the rope correspond. This well-known device has, because of the large contact surface the specific pressure on the rope is reduced and this is unhindered around his Can rotate (spin) the longitudinal axis, in the sense of an extraordinary rope protection and A smooth placing and lifting of the load has proven to be excellent, but it is satisfactory only if the inclination of the path does not exceed a certain limit; from one certain inclination of the path there is a risk that the load placed on the rope slides along the rope.

Diese Rutschgefahr wird erfindungsgemäß dadurch beseitigt, daß die drehbaren Stützrollen auf diesen Bolzen begrenzt axial verschiebbar sind und ihre Drehbewegung durch Reibmittel abbremsbar ist, so daß in der Steigung oder Neigung der Bahn die eine Rolle fest gebremst wird und die andere lose bleibt. Diese Wirkung kann durch Reibung zwischen Stützrolle und Gehäuse oder zwischen Stützrolle und Rollenbolzen herbeigeführt werden. Im ersten Falle kann die Stirnfläche der Stützrolle eben oder kegelig als Reibfläche ausgebildet sein, im zweiten Falle ist die Stützrolle mit einem Hohlkegel und der Rollenbolzen mit einem entsprechenden Reibkegel versehen. Weiterhin sind erfindungsgemäß die die Rollenreibung herbeiführenden Mittel nur an einem Ende jeder Stützrolle angebracht, und zwar bei der einen Rolle, in Förderrichtung gesehen, vorn und bei der anderen hinten.This risk of slipping is eliminated according to the invention in that the rotatable support rollers are axially displaceable to a limited extent on these bolts and their rotational movement can be braked by friction means, so that in the Incline or incline of the path that one role is firmly braked and the other remains loose. This effect can be caused by friction between the support roller and the housing or between the support roller and the roller bolt be brought about. In the first case, the end face of the support roller can be flat or conical be designed as a friction surface, in the second case the support roller is with a hollow cone and the roller pin is provided with a corresponding friction cone. Furthermore, according to the invention, the roller friction inducing means attached only to one end of each support roller, namely at one roller, seen in the direction of conveyance, at the front and the other at the back.

Die Erfindung ist in der Zeichnung beispielsweise dargestellt an einer Tragvorrichtung für Einseilbahnen, bei der die Stützrolle mit einem Hohlkegel und der Drehbolzen mit einer konischen Verdickung versehen ist, lind zwar zeigt:The invention is shown in the drawing, for example, on a support device for single-cable railways, where the support roller with a hollow cone and the pivot pin is provided with a conical thickening, although it shows:

Claims

mens or bar 2, which is supported on the rope 5 with the carrying shoes 3 and 4, which can be moved to a limited extent in the rope direction to serve. In the supporting shoes-f ^ J 4 and two each are coaxial to the rope Toggle ^S: parent support rollers 6 and 7 mounted rotatably mounted on their coats helical ;, corresponding to the impact of the rope shaped hollow grooves. As FIG. 3 shows, these rollers are provided at one end with a hollow cone 10 which cooperates with the cone 11 (FIG. 4) of the bolt 12. As the section in Fig. 2 shows, in the direction of movement indicated by the arrow, the left roller 7 at the front and the right roller 6 at the rear are provided with the friction cone. The other support shoe 4 is designed in exactly the same way. When the rope is inclined, the carriage with the support shoes and the bolts is pulled downwards, while the support rollers are carried along by the frictional engagement of their screw grooves with the strands of the rope; Both rollers are thus axially shifted somewhat in the same direction, whereby one roller 7 is increasingly pressed onto the conical thickening 11 of the bolt with increasing slope and is prevented from rotating, while the other roller 6 is pulled off the cone of the other bolt and can rotate freely. Because one roller is clamped while the opposite one can rotate freely, a certain wedge-clamping effect is achieved, which guarantees an absolutely non-slip fit on the rope. Due to the mutual arrangement of the friction means, the clamping effect must occur, regardless of whether the car is on an uphill or downhill slope.

The device thus combines the advantages of extraordinary rope protection (unhindered spinning of the rope) and the impact-free placing and lifting of the load the advantage of an absolutely secure press fit on the rope and the exclusion of everyone f.Possibility to slide regardless of the changing position Inclination of the path.
