Abstract
Description
Die Erfindung betrifft ein Verbindungssystem für Förder gurte aus Gummi, PVC o. dgl., wobei die Verbindungswirkung überwiegend durch bei der Verbindungsherstellung einge brachte Haftstoffe und Zugübertragungselemente erzielt wird.The invention relates to a connection system for conveying belts made of rubber, PVC or the like, the connecting effect predominantly turned on when connecting brought adhesives and train transmission elements achieved becomes.
Die bei der Ausführung der Verbindungen zum Tragen kommen den Varianten sind sog. Fingersplice mit Gewebeabdeckung in Längen bis zu mehreren Metern für Einlagengurte, oder Verbindungen mit gestoßenem oder überlapptem Zugträger mit eventuell eingebrachtem Zwischenzugträger für Zwei- und Mehrlagengurte. Allen Verbindungen ist gemeinsam, daß sie nur einen Bruchteil der Gurtdauerfestigkeit er reichen. Der Verbindungsausfall durch Überbeanspruchung beginnt bei fehlerfrei hergestellten Verbindungen sehr oft an den äußeren Enden der Verbindung und wandert immer weiter in die Verbindung hinein. Zusätzlich sind die oft mehrere Meter langen Fingersplice-Verbindungen wegen ihrer Länge schwierig in der Herstellung und benötigen große Vulkanisiergeräte, was einen nicht unerheblichen Aufwand zur Folge hat.Which come into play when making the connections the variants are so-called finger splices with tissue covering in lengths of up to several meters for insert straps, or Connections with butted or overlapped tension members with possibly inserted intermediate tension beam for two and multi-layer belts. All connections have in common that they are only a fraction of the belt fatigue strength pass. The connection failure due to overuse starts very well with connections made correctly often at the outer ends of the link and always wanders further into the connection. In addition, they are often finger splice connections several meters long because of their Length difficult to manufacture and require large ones Vulcanizing equipment, which is a considerable effort has the consequence.
Der Erfindung liegt die Aufgabe zugrunde, die bekannte Fingersplice-Verbindung derart zu verbessern, daß die Verbindung bei erheblich kürzerer Ausführung mindestens gleichwertig belastbar ist. The invention has for its object the known To improve the finger splice connection in such a way that the Connection with a significantly shorter version at least is equally resilient.
Die Lösung der gestellten Aufgabe besteht darin, daß bei den in die Verbindung eingebrachten zusätzlichen Zugkraft übertragungselementen die Enden der Zugkraftübertragungs elemente mechanisch mit dem Gurtzugträger verbunden werden. Somit wird die kritische Stelle der Verbindung derart gesichert, daß sie zusätzliche Kräfte übertragen kann und somit eine kürzere Verbindung möglich ist.The solution to the problem is that the additional pulling force introduced into the connection transmission elements the ends of the traction transmission elements are mechanically connected to the belt tension member. Thus the critical point of the connection becomes like this assured that it can transmit additional forces and thus a shorter connection is possible.
In Weiterbildung der Erfindung ist das Zugkraftübertra gungselement ein Einzelcord in entsprechender Dimensio nierung und in der erforderlichen Dichte, der anstelle des Abdeckgewebes über die Finger vernäht wird oder ein beidseitig aufgelegtes Abdeckgewebe, dessen einzelne Kett fäden in den Zugträger vernäht werden.In a further development of the invention, the tensile force is transmitted a single cord in corresponding dimensions nation and in the required density, which instead of the covering fabric is sewn over the fingers or a covering fabric applied on both sides, the single warp threads are sewn into the tension member.
Das Vernähen erfolgt vorteilhafterweise so, daß in eini gem Abstand von den Fingerfüßen dünne Bohrungen in den Gurtkörper eingebracht werden, durch die die zugtragenden Fäden der Zusatzgewebekette geführt werden. Die Bohrungen werden vorteilhafterweise in mehreren Zeilen angeordnet, damit der Zugträgerquerschnitt des Gurtes nicht zu sehr geschwächt wird. Die übrigen Verbindungselemente können wie bei herkömmlichen Fingersplicen ausgeführt sein.The sewing is advantageously carried out so that in one According to the distance from the finger feet, thin holes in the Belt body are introduced through which the tensile Threads of the additional fabric chain are guided. The holes are advantageously arranged in several lines, so that the tension member cross section of the belt is not too much is weakened. The other connecting elements can as with conventional finger splices.
Die Zugkraftübertragung erfolgt in der erfindungsgemäßen Verbindung bei normaler Belastung der Verbindung wie beim bekannten Fingersplice. Bei hoher Belastung der Verbindung wird ein Teil der Kräfte über die Abdeckfäden bzw. Abdeck gewebe über die formschlüssige Durchführung der Fäden durch den Gurtkern in den Gurtkörper eingeleitet. Dabei ist für das erfindungsgemäße System die hohe Metallhaken festigkeit der heute eingesetzten Fördergurte von großem Nutzen, der große Abstand der Corddurchführungsbohrung vom Fingerfuß in Kombination mit der hohen Hakenfestig keit vermeidet ein Auskämmen der Corde nahezu ganz.The traction is transmitted in the invention Connection with normal loading of the connection as with known finger splice. At high load on the connection becomes a part of the forces over the covering threads or covering fabric on the form-fitting implementation of the threads introduced into the belt body through the belt core. Here is the high metal hook for the system according to the invention strength of the conveyor belts used today of great Benefit, the large distance of the cord feed-through hole from the finger base in combination with the high hook strength combing the cords almost completely.
Ein weiterer Nutzen der Durchführung der Abdeckgewebefäden durch den Gurtkern ist, daß Teilausfälle des herkömmlichen Verbindungsteils durch die sicherere Kraftüberleitung partielle Mehrbelastungen wesentlich besser übertragen werden können.Another benefit of carrying the cover fabric threads through the belt core is that partial failures of the conventional Connecting part through the safer power transmission partial additional burdens transferred much better can be.
Die Erfindung ist anhand einer Zeichnung näher erläutert.The invention is explained in more detail with reference to a drawing.
Bei dem gewählten Ausführungsbeispiel handelt es sich um die Ausführung, bei der ein Cord (1) über die Ver bindung vernäht wird (7). Die beiden Gurtenden 2, 3 sind bereits gefingert (5), und in diesem Ausführungsbeispiel jeweils in zwei Zeilen (4) gebohrt. Zwischen Cord 1 und Gurtkörper und zwischen den Fingern ist ein Haft system (6), welches auch außerhalb der Bohrungen eine Kraftübertragung zwischen Fingerbereich und Cord gewähr leistet.The selected embodiment is the version in which a cord ( 1 ) is sewn via the connection ( 7 ). The two belt ends 2 , 3 are already fingered ( 5 ), and in this embodiment each are drilled in two rows ( 4 ). Between the cord 1 and the belt body and between the fingers is an adhesive system ( 6 ), which ensures a force transmission between the finger area and cord even outside the holes.
In diesem Ausführungsbeispiel beträgt die Fingerlänge 300 mm und die gesamte Verbindungslänge 500 mm, sie ist also mit relativ geringem Aufwand und kleinem Gerät herstellbar.In this embodiment, the finger length is 300 mm and the total connection length 500 mm, it is So with relatively little effort and small device producible.
Der gesamte Verbindungsbereich ist wie beim bisherigen System mit einer Deckplatte abgedeckt.The entire connection area is the same as the previous one System covered with a cover plate.
