Description

Die Erfindung betrifft eine Aufhängung für die Fahrschiene oder dgl. eines Hebezeuges an einem Träger gemäß dem Oberbegriff des Anspruches 1.The invention relates to a suspension for the rail or the like. A hoist a carrier according to the preamble of claim 1.

Aus einem Prospekt der Demag Material Handling Equipment ist eine Redundanz-Aufhängung für Fahrschienen (Kranbahnen und Einschienenbahnen) bekannt, bei der die Fahrschiene zusätzlich mit einem Stahlseil abgesichert ist. Redundanz-Aufhängungen haben die Aufgabe, bei Versagen der eigentlichen Aufhängung, welche üblicherweise durch eine Schraubverbindung gebildet ist, die Tragfunktion zu übernehmen. Hierzu wird das Stahlseil um den oberen Träger gelegt und durch die Öffnung eines zusätzlich an der Fahrschiene befestigten Tragelements geführt. Die Seilenden sind als Kauschen ausgebildet, welche die Seilenden fest miteinander verbinden, wobei das Seil einen geschlossenen Ring bildet.A redundancy suspension is from a brochure of Demag Material Handling Equipment known for rails (crane tracks and monorails), in which the track is additionally secured with a steel cable. Redundancy suspensions have the task if the actual suspension fails, which is usually caused by a Screw connection is formed to take over the supporting function. For this, the steel cable is turned around placed the upper beam and through the opening of an additional one on the running rail attached support element guided. The rope ends are designed as thimbles, which the Firmly connect the rope ends to each other, the rope forming a closed ring.

Nachteilig ist bei dieser Lösung, daß bei stoßartiger Belastung, beispielsweise bei einem Abreißen der Fahrschienenbefestigung, die Redundanz-Aufhängung häufig ebenfalls reißt oder zumindest die Seile durch die Seilklemmen beschädigt werden.The disadvantage of this solution is that in the case of shock loads, for example one Tearing off the rail fastening, the redundancy suspension often also tears or at least the ropes are damaged by the rope clamps.

Die Aufgabe der Erfindung ist es, eine Seilverbindung für eine Redundanz-Aufhängung vorzuschlagen, bei der die o.g. Nachteile vermieden werden.The object of the invention is to provide a cable connection for a redundancy suspension to propose where the above Disadvantages are avoided.

Die Lösung dieser Aufgabe ergibt sich erfindungsgemäß durch die in dem Patentanspruch 1 angegebenen Merkmale. Durch die kennzeichnenden Merkmale der Unteransprüche 2 bis 6 ist die Aufhängung in vorteilhafterweise weiter ausgestaltet.This object is achieved according to the invention by the method described in claim 1 specified characteristics. Due to the characterizing features of dependent claims 2 to 6 advantageously designed the suspension further.

Die Erfindung sieht vor, daß die Seilenden lösbar durch ein Verbindungselement miteinander verbunden sind, das aus zwei baueinheitlich miteinander verbundenen Keilschlössern besteht, die derartig angeordnet sind, daß das eine Keilschloß um 180 Grad gegenüber dem anderen Keilschloß verdreht ist, so daß die von entgegengesetzten Richtungen einlaufenden Seilenden nach Umlenkung um die Keile der Keilschlösser entgegen Ihrer Einlaufrichtung zurückführbar, von den Keilen mindestens unter Last klemmbar und dementsprechend die Wirkrichtungen der die Seilenden klemmenden Keile entgegengesetzt sind. Hierdurch wird erreicht, daß sich das Seil beim Auftreten einer stoßartigen Belastung gegen den Reibungswiderstand des Keilschlosses festzieht, das sich dabei erwärmt und die stoßartig auftretende kinetische Energie absorbiert.The invention provides that the rope ends releasably together by a connecting element are connected, which consists of two wedge locks connected to each other which are arranged in such a way that one wedge lock is 180 degrees from the other Wedge lock is twisted so that the rope ends entering from opposite directions after deflection around the wedges of the wedge locks, they can be returned against the direction of entry, can be clamped by the wedges at least under load and accordingly the effective directions of the the wedges jamming the rope ends are opposite. This ensures that the Rope when a sudden load against the frictional resistance of the Wedge lock tightens, which heats up and the sudden kinetic Absorbs energy.

Eine vorteilhafte Ausführung des Verbindungselementes sieht vor, daß jedes Keilschloß aus einer Grundplatte und einer aufgesetzten Tasche mit einem keilförmigen Raum zur Aufnahme des korrespondierenden, einsteckbaren Keils gebildet ist.An advantageous embodiment of the connecting element provides that each wedge lock a base plate and a patch pocket with a wedge-shaped space for receiving of the corresponding insertable wedge is formed.

Zweckmäßigerweise ist der Keil in Einlaufrichtung frei verschiebbar, so daß die Seilverbindung im lastfreien Zustand einfach gelöst werden kann.The wedge is expediently freely displaceable in the direction of entry, so that the cable connection can easily be released in a load-free state.

Ein einfach aufgebautes Verbindungselement besteht aus zwei Keilschlössern, die eine gemeinsame Grundplatte als Verbindungselement aufweisen.A simply constructed connector consists of two wedge locks, one have common base plate as a connecting element.

Um das Seil gegen ein Herausgleiten zu sichern, ist das Seilende mit einer Seilklemme versehen.To secure the rope against sliding out, the rope end is with a rope clamp Mistake.

Zur effektiven Absorption der kinetischen Energie bei stoßartiger Belastung wird vorgeschlagen, daß der Keilwinkel in einem Winkelbereich zwischen 10 Grad und 14 Grad liegt.For effective absorption of the kinetic energy in the case of impact loads suggested that the wedge angle be in an angular range between 10 degrees and 14 degrees lies.

Die Enden 9a, 9b des Seiles sind durch ein Verbindungselement 10 fest miteinander verbunden. Das Verbindungselement 10 ist in Fig. 3 und Fig. 4 (Draufsicht) deutlicher zu erkennen. Es besteht aus einer Grundplatte 11, die auf jeder Seite ein Keilschloß 12, 13 trägt. Damit sind die beiden Keilschlösser 12, 13 über die Grundplatte 11 gleichzeitig miteinander verbunden. Jedes Keilschloß besteht also aus der gemeinsamen Grundplatte 11 und einer darauf befestigten Tasche 14, 15, die in ein Blech eingeformt ist. Die Keilschlösser sind jeweils um 180 Grad zueinander verdreht; in der Draufsicht in Fig. 4 ist die obere Öffnung 16 des Keilschlosses 12 und die untere Öffnung 17 des Keilschlosses 13 zu sehen. Der Innenraum der Taschen 14, 15 ist keilförmig ausgebildet und weist jeweils zwei Seitenflächen auf, die in ihrer gedachten Verlängerung unter einem spitzen Winkel, dem Keilwinkel, aufeinander zulaufen. Der Keilwinkel liegt im Ausführungsbeispiel bei 14 Grad. In die Tasche ist von einer Seite ein korrespondierend geformter Keil 18, 19 einsteckbar, der im wesentlichen denselben Keilwinkel aufweist. Wie aus Fig. 3 zu entnehmen ist, laufen die Enden des Seiles von entgegengesetzten Richtungen in die keilförmigen Taschen ein und werden dann um den Keil herum geführt. Der Keil 18, 19 ist zumindest in Einlaufrichtung frei verschiebbar.The ends 9a, 9b of the rope are fixed together by a connecting element 10 connected. The connecting element 10 is more clearly shown in FIGS. 3 and 4 (top view) detect. It consists of a base plate 11 which carries a wedge lock 12, 13 on each side.

Each wedge lock consists of the common base plate 11 and one pocket 14, 15 fastened thereon, which is molded into a metal sheet. The wedge locks are each rotated by 180 degrees to each other; 4 is the top opening 16 of the Wedge lock 12 and the lower opening 17 of the wedge lock 13 can be seen. The interior the pockets 14, 15 are wedge-shaped and each have two side surfaces which in their imaginary extension at an acute angle, the wedge angle approach. The wedge angle is 14 degrees in the exemplary embodiment. In the pocket is one Side a correspondingly shaped wedge 18, 19 insertable, which is essentially the same Has wedge angle. As can be seen from Fig. 3, the ends of the rope run from opposite directions in the wedge-shaped pockets and then around the wedge led around. The wedge 18, 19 is at least freely displaceable in the direction of entry.

Das Seil liegt abschnittsweise quer zu seiner Längsrichtung auf beiden Seite seines Außenumfangs jeweils am Keil und an den Innenflächen der Tasche an; es wird nach Umlenkung um die Keile 18, 19 der Keilschlösser12, 13 entgegen ihrer Einlaufrichtung zurückgeführt. Zumindest unter Last ist das Seil 9 von den Keilen 18, 19 klemmbar. Die Wirkrichtungen der die Seilenden 9a, 9b klemmenden Keile 18, 19 sind also entgegengesetzt. Zur Sicherung der Seilenden 9a, 9b sind Seilklemmen 20a, 20b - wie in Fig. 1 gezeigt - vorgesehen.
