Abstract
Description
Fördergurt Die Erfindung bezieht sich auf Fördergurte aus Gummi oder gummiähnlichen Kunststoffen mit in einer Ebene zwischen einer oberen und einer unteren plastomeren Deckplatte eingebetteten, in Längsrichtung ohne gegenseitige Berührung durchlaufenden Drahtseilen, Kabeln oder anderen fadenförmigen Festigkeitsträgern und unabhängig von diesen in einer oder mehreren Lagen eingebetteten, im wesentlichen in Querrichtung ohne gegenseitige Berührung über die Gurtbreite verlaufenden zusätzlichen fadenförmigen Festigkeitsträgern.Conveyor belt The invention relates to conveyor belts made of rubber or rubber-like plastics with in a plane between an upper and a lower plastomer cover plate embedded, lengthways without mutual contact continuous wire ropes, cables or other thread-like reinforcements and, independently of these, embedded in one or more layers, essentially in the transverse direction without mutual contact across the belt width additional thread-like reinforcements.
Die meistens als ''Svah seil-ördergurte't Sezeichneten Fördergurte mit ausschließlich in Längsrichtung orientierten Verstärkungseiniagen sin zwar in der Lage, hohe und hochEte Zugl-rorte aufzunehmen und daher besonders für schwere Beanspruchungen mit laugen Förderstrecken geeignet, ihre im Vergliech zu gew@@@@@erstärkten Fördergurten re Anfälligkeit gegen Aufschlitzschäden macht es andererseits aber of r.otwendig, sie mit zusätzlichen Quereislagen zu armieren, was in vielen Fällen je nach den vorkommenden Sinsatzbedingungen auch schon als Durchschlagschutz gegen aufprallendes scharfkantiges Fördergut verlangt wird.The conveyor belts mostly identified as '' Svah seil-ördergurte't Se with reinforcement elements oriented exclusively in the longitudinal direction are indeed in able to accommodate high and high tensile places and therefore especially for heavy Stresses with long conveyor lines are suitable to strengthen theirs in comparison to gew @@@@@ On the other hand, however, it makes conveyor belts more susceptible to damage due to slashing It is often necessary to reinforce them with additional transverse layers, which in many cases Depending on the operating conditions that occur, it can also act as a puncture protection against impacting sharp-edged conveyed goods are required.
Für diese Zwecke haben sich ähnlich den Längsverstärkungen aus ebenfalls in Kordlage berührungsfrei nebeneinander angeordneten Drahtseilen od.For these purposes, similar to the longitudinal reinforcements have also been made wire ropes arranged side by side in a non-contacting cord position or
dgl. aufgebaute Quereinlagen im praktischen Förderbetrieb schon vielfach bewährt. Der Ausdruck "Quereinlagen" ist hierbei in dem vorliegenden Zusammenhang im weitesten Sinne, d.h. also auch spitze Winkel gegen die Gurtkante einschließend zu verstehen. Von Aufgabestationen und anderen wenigen Sonderfällen abgesehen werden die Fördergurte in aller Regel aber im Last um gemuldet geführt, um ihre durch den festliegenden Böschungswinkel des Fördergutes begrenzte Förderkapazität zu steigern, und diese erwünschte Muldungsfähigkeit wird durch die zusätzlichen Quereinlagen erheblich beeinträchtigt. Dies gilt besonders, wenn sich die Quereinlagen über und unter den Längsfestigkeitsträgern befinden. Da weder auf die Schutzfunktion der Quereinlagen noch auf die Muldbarkeit verzichtet werden kann, waren bisher stets nur Kompromißlösungen anzustreben, wobei mit der Wahl möglichst biegsamer, aber noch ausreichend widerstandsfähiger Festigkeitsträger für die Quereinlagen als Folge der dadurch höheren Quersteifigkeit gewisse Verschlechterungen im dynamischen Verhalten der Fördergurte und unvermeidliche Einbußen in der Förderleistung hingenommen werden mußten.Like. built-up cross inserts in practical conveyor operation already many times proven. The term "cross inserts" is used here in the present context in the broadest sense, i.e. also including acute angles against the belt edge to understand. Dispensing stations and other few special cases are not included the conveyor belts usually but carried in the load around troughed to their through the fixed slope angle of the conveyed goods to increase limited conveying capacity, and this desired troughability is made possible by the additional cross-inserts significantly impaired. This is especially true if the cross inserts are over and are located under the longitudinal strength beams. Since neither on the protective function of the Cross-inserts still waived the tolerance can be, were so far only to strive for compromise solutions, whereby with the choice as flexible as possible, but still sufficiently resistant reinforcements for the cross inserts as a result of the resulting higher transverse rigidity, certain deteriorations in the dynamic Accepted behavior of the conveyor belts and inevitable losses in the conveying capacity had to be.
Die Aufgabe der Erfindung ist demgegenüber darin zu sehen, den versteifenden Einfluß der Quereinlagen auf das Biegeverhalten der Fördergurte in Querrichtung ohne Verminderung ihrer erwünschten Schutzwirkung abzuschwächen und in weitergehendem Maße als bisher möglich aufzuheben. Diese Aufgabe wird für Fördergurte der eingangs geschilderten Art dadurch gelöst, daß die zusästzlichen Restigkeitsträger auf beiden Seiten mit einer die Verbindung zu dem elastomeren Gurtwerstcff herstellenden Schicht eines nichtvulkanisierbaren plastischen Werkstoffes, vorzugszeile einer aus 2 - Ohlorbutadien - (1, 3) - Polymerisaten hergestellte Mischung, bedeckt sind.The object of the invention is to be seen in contrast to the stiffening Influence of the cross inserts on the bending behavior of the conveyor belts in the cross direction without diminishing their desired protective effect and in further detail Measures to be saved as previously possible. This task is carried out for conveyor belts at the beginning described type solved in that the additional residual carriers on both Sides with a layer that establishes the connection to the elastomeric belt structure a non-vulcanizable plastic material, preferred line one of 2 - Ohlorbutadiene - (1, 3) - polymers produced mixture, are covered.
Die Erfindung ersetzt die bisher vorherrschende direkte Haftverbindung der Quereinlagen mit den benachbarten Gummischichten des Gurtkörpers dnrch eine gleichsam ischwimmende" Einbettung der einzelnen Festigkeit$= träger in einer plastisch verformbarer Zischenschicht1 die diesen eine begrenzte Bewegungröglicheit um Ausgleichen von Spannungen im Ablauf der dynamischen Gurt verformungen verleiht L'ls überreschende Folge hiervon zeigen die erfindungsgemäßen Fördergurte eine unerwartete Biegewilligkeit in Querrichtung! woraus sich wiederum beträchtliche Verbesserungen in den Laufeigenschaften und schließlich auch in der Förderleistung herleiten. Als mittelbarer Vorteil tritt hierzu die freizügige Auswahlmöglichkeit für die Elemente der QuereinlagenX die nicht mehr nach besonders hoher Konstruktionsdehnung auszulegen sind, sondern allein nach den maß gelblichen Festigkeitsbeanspruchungen und Wirtschaftlichkeitsüberlegungen ausgesucht und dimensioniert werden können.The invention replaces the hitherto predominant direct adhesive connection of the cross inserts with the adjacent rubber layers of the belt body through one as it were "floating" embedding of the individual strength $ = carrier in a plastic deformable interstitial layer 1 that allows limited movement to compensate for this of tension in the course of dynamic belt deformations gives L'ls surprising As a result, the conveyor belts according to the invention show an unexpected flexibility in transverse direction! which in turn results in considerable improvements in the running properties and finally also in the delivery rate. Occurs as an indirect benefit for this purpose the free choice for the elements of the cross-insertsX the are no longer to be designed according to particularly high structural elongation, but solely according to the yellowish strength stresses and economic considerations can be selected and dimensioned.
Für Fördergurte mit in nur einer Lage über oder unter den längs durchlaufenden Festigkeitsträgern vorgesehenen Quereinlagen wirkt sich die Erfindung in noch weiterer Hinsicht günstig aus. Da die Gurte als Folge der abschließenden Vulkanisation über ihren gesamten Querschnitt zu schrumpfen suchen, an diesem Schrumpfen aber durch die Quereinlagen gehindert werden, führt die einseitige Querarmierung stets zu unerwünschten Wölbungen einer Gurtoberfläche. Die Erfindung dagegen ermöglicht das Nachgeben der Deckplatten auf beiden Seiten des Gurtkernes und ein ungehindertes Ausgleichen der Schrumpfbewegung in allen Teilen, so daß sich ein in allen Teilen verbessertes Erzeugnis ergibt.For conveyor belts with only one layer above or below the lengthways Reinforcements provided transverse inserts affects the invention cheap in other ways. Because the straps as a result of the final Vulcanization tries to shrink over its entire cross-section, due to this shrinkage but are hindered by the cross inserts, the one-sided cross reinforcement leads always leads to undesirable curvatures on a belt surface. The invention, however, enables the yielding of the cover plates on both sides of the belt core and an unhindered Compensate for the shrinkage movement in all parts, so that there is one in all parts improved product results.
Die von den längs durchlaufenden Festigkeitsträgern unabhängige Unterbringung der Quereinlagen in dem Gurtkörper gestattet es, die Verbindungaschicht, die die zusätzlichen Festigkeitsträger lückenlos und ganzflächig bedeckt, als Mittel zum Anzeigen unzulässiger Verschleißerscheinungen in den äußeren Deckplatten auszunutzen, wenn sie gemäß einem Teilmerkaal der Erfindung eine von den Deckplatten abweichende Farbgebung aufweist. Durch den Fortfall der üblichen Vulkanisiermittel und Rußanteile ist die Verbindungsschicht im allgemeinen schon von vornherein auffallend heller gefärbt als die stark rußhaltigen vulkanisierbaren Gummimischungen. Dieser Effekt kann gegebenenfalls durch Zumischen anderer Füll- oder Zusatzstoffe noch weiter gesteigert werden, um auch an den bewegten Fördergurten Verschleißstellen, die bis in gefährliche Nähe des Gurtkernes mit den längs durchlaufenden Festigkeitsträgern reichen, durch Freilegen der Verbindungsschicht über der zwischen dem Kern und der betroffenen Deckplatte eingebetteten Quereinlage mit Sicherheit zu erkennen.The accommodation that is independent of the longitudinal reinforcements the transverse inserts in the belt body allows the connecting layer that the additional reinforcement completely and completely covered, as a means for To exploit indications of impermissible signs of wear in the outer cover plates, if they differ from the cover plates according to a partial feature of the invention Has coloring. By eliminating the usual vulcanizing agents and soot components the connecting layer is generally noticeably lighter from the start colored than the vulcanizable rubber compounds with a high carbon black content. This effect can optionally be added further by adding other fillers or additives be increased to wear points on the moving conveyor belts that are up in dangerous proximity to the belt core with the longitudinal reinforcement members range by exposing the tie layer over that between the core and the The affected cover plate embedded transverse insert can be identified with certainty.
Die Erfindung ist anhand der schematischen Darstellung eines Ausführungsbeispiels in der Zeichnung verdeutlicht. Die einzige Figur der Zeichnung zeigt einen Abschnitt eines erfindungsgemäßen Stahlseil-Fördergurtes im Querschnitt.The invention is based on the schematic representation of an embodiment illustrated in the drawing. The only figure in the drawing shows a section of a steel cord conveyor belt according to the invention in cross section.
Der gezeichnete Fördergurt ist aus Gummideckplatten 1, 2 mit zwischen diesen in eine Kerngummischicht 3 eingebetteten längs durchlaufenden Drahtseilen 4 und einer zwischen den Drahtseilen 4 und der oberen Deckplatte 1 angeordneten Quereinlage aus zusätzlichen Drahtseilen 5 aufgebaut. Dieses Grundsatz-Aufbauschema für Stahlseil-Fördergurte ist an sich bekannt und läßt in der Zuordnung der einzelnen Komponenten zueinander oder in ihrer Anzahl und Dimensionierung und in anderen Einzelheiten mannigfache Änderungen zu, ohne damit den Rahmen der Erfindung zu verlassen.The drawn conveyor belt is made of rubber cover plates 1, 2 with between these embedded in a core rubber layer 3 longitudinally running wire ropes 4 and one arranged between the wire cables 4 and the upper cover plate 1 Transverse insert made up of additional wire ropes 5. This basic construction scheme for steel cord conveyor belts is on known and leaves in the assignment of the individual components to each other or in their number and dimensions and various changes in other details without thereby departing from the scope of the invention to leave.
Gemäß der Erfindung sind die zusätzlichen Drahtseile 5 der Quereinlage in eine beispielsweise aus 2 - Chlorbutadien - (1, 3) - Polymerisaten hergestellte Verbindungsschicht 6 eingebettet. Die Verbindungsschicht 6, die in Form eines nur dünnen Aufstriches auf die Drahtseile 5 aufgebracht werden kann und die Zwischenräume zwischen diesen vollständig ausfüllt, liegt unmittelbar an der oberen Deckplatte 1 auf der einen Seite und an der Kerngummischicht 3 auf der anderen Seite an und stellt die durc'lgehende Verbindung im Schichtenaufbau des Gurtkörpers her. Da sie ihre Plastizität auch nach dem Fertigvulkanisieren des Fbrdergurtes beibehält, ermöglicht sie den eingebetteten Drahtseilen 5 den für die technische Wirkung der Erfindung wesentlichen Bewegungsspielraum.According to the invention, the additional wire ropes 5 are the transverse insert into one prepared, for example, from 2-chlorobutadiene (1, 3) polymers Connection layer 6 embedded. The connecting layer 6, which is in the form of one only thin spread can be applied to the wire ropes 5 and the spaces completely filled between these, lies directly on the upper cover plate 1 on one side and on the core rubber layer 3 on the other side on and creates the continuous connection in the layer structure of the belt body. Since they maintains their plasticity even after the conveyor belt is fully vulcanized they the embedded wire ropes 5 for the technical effect of the invention essential freedom of movement.
