Abstract
Description
Förderband mit Stahlseileinlage Die rfinduiig bezieht sich auf ein Förderband aus Gummi oder gummiähnlichem Kunststoff mit in Längsrichtung eingebetteten Stahlseilen als Zugträger und quer dazu unter der Deckplatte eingebetteten Seilen. Conveyor belt with steel cable insert The rfinduiig refers to a Conveyor belt made of rubber or rubber-like plastic with embedded lengthways Steel cables as tension members and cables embedded across them under the cover plate.
Zur Vermeidung von Schäden an Förderbändern mit in Längsrichtung verlufenden Stahlseilen ist es bekannt, in :uerrichtung hierzu verschiedene Schlitzschutzeinrichtungen vorzusehen. Neben den eingebetteten1 elektrisch überwachten Drahtschleifen sind auch in Quer-Se,ile B richtung eingebetteteYals mechanischer Jchlitzschutz bekannt gewordene Die elektrisch überwachten Sciilitzschutzeinrichtungen erfordern einen erheblichen technischen Aufwand. Dennoch können sie in manchen Fällen die an sie gestellten Anforderungen nicht erfüllen. Die in uerrichtung eingebetteten Stahlseile ls mechanischer Schiitzschutz erfüllen ihre Aufgabe nach den bisherigen Erfahrungen ebenfalls nicht ausreichend. Sind die uerseile in grösseren Abständen angeordnet, so müssen sie einen beträchtlichen durch messer aufweisen. Dies beeinträchtigt den gleichmässigen Lauf des sandes und ferner die gleichmässige Eluldungsfähigkeit. Der oberen Stahlseildicke sind ferner Grenzen gesetzt, da diese sonst zu einer relativ verminderten Festigkeit bei einer Schlingenbildung führt.In order to avoid damage to conveyor belts with steel cables running in the longitudinal direction, it is known to provide various slot protection devices in this direction. In addition to the embedded1 electrically monitored wire loops, there are also embedded wires in the transverse direction as mechanical slit protection The electrically monitored lightning protection devices require considerable technical effort. Nevertheless, in some cases they cannot meet the requirements placed on them. The steel cables embedded in the structure as mechanical protection against accidental damage do not adequately fulfill their task according to previous experience either. If the outer ropes are arranged at greater intervals, they must have a considerable diameter. This impairs the smooth running of the sand and also the smooth elulability. There are also limits to the upper steel rope thickness, as this would otherwise lead to a relatively reduced strength when a loop is formed.
Ausserdem sind Gezebeeinlagen als Schlitzschutz vorgesehen, bei denen die Festigkeit in suerrichtung überwiegt. Die Herstellung und Verarbeitung solcher Gewebe ist schwierig und kostspielig. Auch diese Einlagen können daher den hohen Anforderungen nicht gerecht werden. Sie lassen auch kaum eine optimale Einstellung auf die Anforderungen an die Schlitzschutzfestigkeit zu.In addition, Gezebe inserts are provided as slit protection, where the strength in the superstructure predominates. The manufacture and processing of such Fabric is difficult and expensive. These deposits can therefore also be high Does not meet requirements. They also hardly leave an optimal setting towards the requirements for the slot protection strength.
Nach den zur Zeit vorherrschenden Vorstellungen soll die Schlitzschutzfestigkeit mindestens das Dreifache der Festigkeit betragen, die das Förderband ohne eine entsprechende Einlage aufweist.According to the prevailing ideas at the moment, the slot protection strength should at least three times the strength of the conveyor belt without a corresponding insert.
Aufgabe der Erfindung ist es, eine aus verseilen bestehende Einlage zu schaffen, die eine einfache Fertigung des Fördergurtes in allen Fertigungsstufen und eine hohe Schlitzschutzfestigkeit schafft, ohne dabei die Laufeigenschaften des Fördergurtes unter den verschiedenen technischen Bedingungen zu beeinträchtigen.The object of the invention is to provide an insert consisting of cords to create a simple production of the conveyor belt in all stages of production and creates a high level of protection against slits without compromising the running properties of the conveyor belt under the various technical conditions.
Zur Lösung dieser Aufgabe st erfindungsgemäss vorgesehen, dass die Querseile entsprechend der eingangs umrissenen Förderbandgestaltung aus Polyamid mit erhöhter Xeissfestigkeit und Dehnbarkeit einen Durchmesser von ca. 2 mm und gegenseitige Abstände von ca. 6 mm aufweisen.To solve this problem, the invention provides that the Cross ropes made of polyamide according to the conveyor belt design outlined at the beginning with increased strength and elasticity a diameter of approx. 2 mm and have a mutual distance of approx. 6 mm.
Für den Erfindungsgedanken sind diese Merkmale von gleichrangiger Bedeutung, um die hohen Anforderungen erfüllen zu können. Die erhöhte Reissfestigkeit und Dehnbarkeit lässt sich durch an sich bekannteSeilkonstruktionen in Verbindungen mit reissfedten Polyamid-Elonofilen erreichen. An Stelle von Polyamid sind auch andere Sythesefasern mit gleichwertigen Eigenschaften brauchbar. Hinzukommen muss dabei eine passende Abmessung des Durchmessers in Verbindung mit den passenden Abständen. Der angegebene Seildurchmesser kann um etwa 50% schwanken. Die Abstände können zwischen 3 und 10 mm liegen. Wichtig ist, dass jeweils eine Abstimmung dieser Abmessungen bezüglich Abstand und Dicke aufeinander folgt. ei diesen kennzeichnenden Merkmalen ist insbesondere die erhöhte Dehnbarkeit von Bedeutung, da hierdurch bei einem Schadensfalls eine grössere Anzahl von Querseilen gemeinsam zum Tragen kommend Diese Dehnbarkeit führt dazu, dass weiter zurückliegende Seile dem Schlitzvorgang am Fördergurt bereits entgegenwirken, bevor das erste Seil gerissen ist. Bei der abmessung der Seile und deren physikalischen Eigenschaften erreicht die Schlingenfestigkeit einen besonders hohen Wert.For the idea of the invention, these features are of equal importance Significance in order to be able to meet the high requirements. The increased tear strength and extensibility can be made into connections by per se known rope constructions with tear-spring-loaded polyamide Elonofilen. Instead of polyamide are also other synthetic fibers with equivalent properties can be used. Must be added a suitable dimension of the diameter in connection with the appropriate distances. The specified rope diameter can vary by about 50%. The distances can be between 3 and 10 mm. It is important that each of these dimensions is coordinated follows one another in terms of distance and thickness. ei these distinguishing features In particular, the increased elasticity is important, as this in the event of damage a larger number of cross ropes come into play together This extensibility leads to the fact that ropes that are further behind have already passed the slitting process on the conveyor belt counteract this before the first rope breaks. When dimensioning the ropes and Their physical properties make the loop strength particularly easy great value.
Sie ann 100 kp pro Seil überschreiten. Unter der Schlingenfestigkeit ist eine Beanspruchung zu verstehen, bei der zwei Seile um 180° geknickt sind und die Seile in den Knickstellen ineinanderliegend auf Zug beansprucht werden. Die Dehungsfähigkeit der Seile beträgt mindestens 15 - 20 ,Ó. Sie .ird durch eine Seilkonstruktion erholten die beispielsweise den Bedingungen 1880x5x3 folgt. Die Festigkeit dieser Seile liegt bei 20G kp Die Seile eisen eine Bruchdehnung von 35 % auf e Nach einer Ausgestaltung des ErfindungsgedanKens kann es zweckmässig sein, dass je eine Querseileneinlage beiderseits der Zugseileneinlage angeordnet ist. Allerdings ist aSuch die anordnung auf einer Seite zu den Zugseilen mit einem erheblichen tecnnischen Fortschritt verbunden. Durch die doppelte wuerseileinlage wird nicht nur die Schlitzschutzwirkung für den Fördergurt vergrössert, es wird auch sichergestellt, dass das Förderband einen symmetrischen Aufbau hatO sie Quereinlagen reichen vorzugsweise bis an die beiden äussersten Zugseile. Nach dem rfindungsged-nken ist es bei besonders gefährdeten Fördergurten auch möglich, mehrere Quereinlagen übereinander anzuordnen und diese dann zu den Seilen hin abzustufen0 Dadurch Wird die besonders gefährdete Bittelzone des Förderbandes gekräftigt. Es ist zweckmässig, die Querseile mit einer vulkanisierfähigen Haftmischung zu versehell. Derartige Haftmischungen sind an sich bekannt0 Die tAischungen sind auf die Eigenschaften der benachbarten Gur.ni- und Kunststoffschichten abgestimmte Die Herstellung eines derartigen Förderbandes ist dadurch vereinfacht, dass die Querseile in einer Kautschukmischungsschicht eingebettet sind. Eine derartige Kordseileinlage wird analog hergestellt, wie dies bei der Fabrikation von Reifenkord bekannt ist. Eine derartige Kordfdeschicht lasst sich recht einfach verarbeiten. Durch diesen Aufbau ist eine Verschiebung der Fäden aus einer Parallelstellung ausgeschlossen. Die Fäden werden in der Schicht gleichmässig straff gehalten bis sie ihren endgültigen Platz in dem Förderband erhalten haben.They can exceed 100 kp per rope. Under the loop strength is to be understood as a load in which two ropes are bent by 180 ° and the ropes lying one inside the other in the kinks are subjected to tensile stress. the The rope's ability to stretch is at least 15 - 20, Ó. It is made by a rope construction recovered which, for example, follows the conditions 1880x5x3. The strength of this The ropes are at 20G kp. The ropes have an elongation at break of 35% after a In the embodiment of the concept of the invention, it can be expedient to have one cross rope insert is arranged on both sides of the pull rope insert. However, such is the arrangement on one side to the pull ropes associated with considerable technical progress. The double wuerseileinlage not only protects the Conveyor belt enlarged, it is also ensured that the conveyor belt is symmetrical The structure has cross inserts that preferably extend to the two outermost traction ropes. According to the concept of the invention, it is also possible for particularly endangered conveyor belts to arrange several cross inserts on top of each other and then to graduate them towards the ropes0 This strengthens the particularly endangered Bittelzone of the conveyor belt. It it is advisable to provide the cross ropes with a vulcanizable adhesive mixture. Such adhesive mixtures are known per se0 The mixtures are based on the properties The production of a Such a conveyor belt is simplified in that the cross ropes are in a rubber compound layer are embedded. Such a cord insert is produced in the same way as this in the manufacture of tire cord is known. Leave such a cord layer process quite easily. This structure causes the threads to shift excluded from a parallel position. The threads are in the layer evenly held taut until they have their final place in the conveyor belt.
