Description

Die Erfindung betrifft ein Kunstfaserseil , vorzugsweise aus aromatischem Polyamid, mit einer Umhüllung nach dem Oberbegriff des Anspruchs 1.The invention relates to a synthetic fiber rope, preferably made of aromatic polyamide, with a covering according to the generic term of claim 1.

Seile sind insbesondere in der Fördertechnik, wie z.B. bei Aufzügen, im Kranbau und im Bergbau, ein wichtiges stark beanspruchtes Maschinenelement. Besonders vielschichtig ist die Beanspruchung von getriebenen Seilen, über Seiltrollen umglenkten Seilen oder auf Trommeln aufgewickelten Seilen, wie sie beispielsweise im Aufzugsbau und bei sSeilbahnen verwendet werden. Dort sind grosse Seillängen notwendig und es besteht aus energetischen Gründen die Forderung nach möglichst kleinen Massen. Hochfeste Kunstfaserseile, beispielsweise aus aromatischen Polyamiden oder Aramiden mit hochgradig orientierten Molekülketten erfüllen diese Anforderungen besser als herkömmliche Stahlseile. Allerdings sind Werkstoffe, wie z.B. Aramide, besonders empfindlich gegenüber ultraviolettem (UV) Licht, oxidierenden und reduzierenden Umwelteinflüssen, durch die die Bruchkraft und das Arbeitsvermögen herabgesetzt werden. Aramidseile werden daher üblicherweise mit lichtbeständigem Material ummantelt oder umflochten.Ropes are particularly useful in conveyor technology, e.g. at Elevators, in crane building and mining, an important strong stressed machine element. It is particularly complex Stress on driven ropes, via rope pulleys deflected ropes or ropes wound on drums, such as it is used, for example, in elevator construction and on cable cars become. Large pitches are necessary there and it exists for energetic reasons the demand for the smallest possible Masses. High-strength synthetic fiber ropes, for example made of aromatic polyamides or aramids with high grade oriented molecular chains better meet these requirements than conventional steel cables. However, materials are like e.g. Aramids, particularly sensitive to ultraviolet (UV) light, oxidizing and reducing environmental influences, by which the breaking force and the work capacity are reduced become. Aramid ropes are therefore usually included light-resistant material encased or braided.

Es ist beispielsweise aus der EP 0 672 781 A1 der Anmelderin bekannt geworden, solche ummantelte Kunstfaserseile bei Aufzugsanlagen als Tragorgane zu verwenden, um den Kabinenrahmen einer in einem Aufzugsschacht geführten Kabine mit einem Gegengewicht zu verbinden. Das Seil läuft über eine Treibscheibe, die zum Heben und senken der Kabine und des Gegengewichts von einem Antriebsmotor angetrieben wird. Das Antriebsmoment wird unter Reibschluss dem jeweils über den Umschlingungswinkel anliegenden Seilabschnitt aufgeprägt. It is for example from the applicant's EP 0 672 781 A1 became known, such sheathed synthetic fiber ropes To use elevator systems as supporting elements to the Cabin frame of a cabin guided in an elevator shaft to connect with a counterweight. The rope runs over a Traction sheave used to raise and lower the cabin and the Counterweight is driven by a drive motor. The The drive torque is in frictional engagement over the Wrap angle stamped on the rope section.

Anstatt einer die gesamte Decklitzenlage umgebenden Ummantelung, ist dort jede einzelne Litze dieser Lage mit einem ringsum geschlossenen extrudierten Mantel aus Kunststoff, vorzugsweise Polyurethan oder Polyamid, versehen, die gesamthaft als Abriebschutz für das Seil dienen und den gewünschten Reibwert zur Treibscheibe gewährleisten.Instead of one that surrounds the entire top strand layer Sheathing, there is every single strand of this layer with one all-round closed extruded plastic sheath, preferably polyurethane or polyamide, provided serve as abrasion protection for the rope and the Ensure the desired coefficient of friction with the traction sheave.

Dort werden die Bindekräfte zwischen den Kunststoffmänteln und der äussersten Kunstfaserlitzenlage erreicht, indem die Kunststoffummantelung unter Druck aufgespritzt wird, so dass alle Zwischenräume zwischen den Litzen ausgefüllt und ein Formschluss mit einer grossen Haltefläche gebildet wird. Die bei Belastung des Seils auftretenden Schubkräfte können unter bestimmten Bedingungen dennoch ein Verschieben oder Aufstauchen der Kunststoffmäntel verursachen. Solche Veränderung des Seils sind unerwünscht, weil sie zum Ausfall des Seils führen könnten. Die nötigen Bindekräfte zwischen Litze und Mantel durch Aufbringen der Litzenmäntel im Druckspritzverfahren darzustellen, gestaltet sich jedoch aufwendig.There the binding forces between the plastic shells and the outermost layer of synthetic fiber reached by the Plastic coating is sprayed on under pressure, so that all gaps between the strands filled and one Form fit with a large holding surface is formed. The shear forces occurring when the rope is loaded can under a shifting or upsetting under certain conditions cause the plastic sheaths. Such change in the rope are undesirable because they lead to rope failure could. The necessary binding forces between the strand and the sheath by applying the strand sheaths in a pressure spray process to represent, however, is complex.

Demzufolge liegt der Erfindung die Aufgabe zugrunde, den Herstellungsaufwand für ein Kunstfaserseil zu verringern, während eine unverändert hohe Funktionalität sichergestellt ist.Accordingly, the invention is based on the object Reduce the manufacturing costs for a synthetic fiber rope, while ensuring an unchanged high functionality is.

Diese Aufgabe wird erfindungsgemäss mit einem Kunstfaserseil der eingangs genannten Art mit den kennzeichnenden Merkmalen des Anspruch 1 gelöst.This object is achieved according to the invention with a synthetic fiber rope of the type mentioned at the outset with the characteristic features of claim 1 solved.

Umfangreiche Versuche der Anmelderin haben ergeben, dass anstelle einer bisher extrudierten, schützenden Ummantelung nur durch eine Beschichtung der Kunstfaserlitzen in der äussersten Litzenlage mit Flüssigkeit, welche UV-Stabilisatoren und andere Zusätze zum Schutz gegen Abrieb und das Seil schädigenden Umwelteinflüssen enthält, ein zuverlässiger UV-Schutz sowie eine ausreichende Abriebfestigkeit des Seiles dauerhaft sichergestellt werden kann.Extensive tests by the applicant have shown that instead of a previously extruded, protective sheath by coating the synthetic fiber strands in the outermost Braid layer with liquid, which UV stabilizers and others Additives to protect against abrasion and rope damage Contains environmental influences, reliable UV protection as well sufficient abrasion resistance of the rope permanently can be ensured.

Die durch die Erfindung erzielten Vorteile bestehen in einer dauerhaften Bindung der Umhüllung an die Kunstfaserlitzen der äusseren Litzenlage, weil das Material der Umhüllung und der die Kunstfasern der Litzen fixierenden Matrix gleich sind. Durch blosses Zumischen entsprechender Zusätze kann die Funktionalität über f die gesamte Lebensdauer von Faserseilen auf einfache Weise verlängert werden. Die erfindungsgemässe Umhüllung bildet weder Aufstauchungen noch ist sie verschiebbar auf den Kunstfaserlitzen. Die Herstellung der Umhüllung erfolgt weitgehend ohne zusätzlichen vorrichtungsmässigen Aufwand und ist einfach und kostengünstig. Ausgehend von grosserienmässig hergestellten herkömmlichen Kunstfaserlitzen sind die Kunstfaserlitzen für die äusserste Faserlitzenlage lediglich durch ein ohnehin vorhandenes Imprägnierungsbad zu ziehen, um die erfindungsgemässe Beschichtung auszubilden. Die Schichtdicke ist über die Verweildauer der Kunstfaserlitze im Imprägnierbad einstellbar. Der Beschichtungsvorgang kann ferner beliebig oft wiederholt werden.The advantages achieved by the invention are: permanent binding of the sheath to the synthetic fiber strands of the outer strand layer, because the material of the covering and the the synthetic fibers of the strand fixing matrix are the same. The mere addition of appropriate additives can Functionality over the entire lifespan of fiber ropes can be easily extended. The inventive Enclosure neither forms upsets nor is it displaceable on the synthetic fiber strands. The casing is produced largely without additional device-related effort and is simple and inexpensive. Starting from mass production conventional synthetic fiber strands are the Synthetic fiber strands for the outermost fiber strand layer only through an existing impregnation bath to to form the coating according to the invention. The Layer thickness is based on the dwell time of the synthetic fiber strand in the Impregnation bath adjustable. The coating process can also can be repeated any number of times.

Eine besonders abriebfeste Ausführungsform der Beschichtung wird durch Zugabe von Kurzfasern, beispielsweise aus Aramid, zum Imprägnierbad erreicht.A particularly abrasion-resistant embodiment of the coating is made by adding short fibers, e.g. aramid, reached to the impregnation bath.

Weitere vorteilhafte Ausführungen der Erfindung sind in den übrigen abhängigen Ansprüchen aufgeführt.Further advantageous embodiments of the invention are in the other dependent claims listed.

Anschliessend ist ein bevorzugtes Ausführungsbeispiel der Erfindung mit Imprägniermittel als Flüssigkeit unter Bezugnahme auf eine in der Zeichnung dargestellte Querschnittsansicht eines aus sechszehn Litzen bestehenden Seils 1 näher beschrieben. Um eine Kernlitze 2 sind fünf gleiche Litzen 3 schraubenlinienförmig gelegt, mit denen fünf dickere Litzen 4 abwechselnd mit fünf dünneren Litzen 5, im Parallelschlag zu einer Decklage 6 verseilt sind. Die für das dargestellte Seil 1 verwendeten tragenden Litzen 2,4,5 sind aus einzelnen Aramidfaserbündeln 7 gedreht oder geschlagen.Then a preferred embodiment of the Invention with impregnating agent as a liquid with reference on a cross-sectional view shown in the drawing a rope 1 consisting of sixteen strands closer described. Around a core strand 2 are five identical strands 3 laid helically, with which five thicker strands 4 alternating with five thinner strands 5, in parallel lay a top layer 6 are stranded. The for the shown rope 1st load-bearing strands 2,4,5 used are made of individual Aramid fiber bundles 7 turned or beaten.

Die Litzen 2,3,4 und 5 bestehen im wesentlichen aus Aramidgarnen 8, die schraubenlinienförmig in einer Matrix aus Polyurethan fixiert sind. Zum Verseilen oder Drehen werden die Aramidgarne 8 mit einem schützenden Imprägnierungsmittel, beispielsweise mit Polyurethanlösung, behandelt. Der Anteil des Polyurethans an jeder Litze 2,4,5 ist mit ausschlaggebend für die Biegewechselfestigkeit des Seils 1. Je höher der Anteil des Polyurethans, desto höher wird die Biegewechselleistung. Mit steigendem Poyurethananteil sinkt der Füllfaktor des gesamten Seiles 1 und damit die Tragfähigkeit und das Dehnungsverhalten des Seils 1. Der Polyurethananteil zur Imprägnierung der Litzen 2,4,5 kann je nach gewünschten Seileigenschaften beispielsweise zwischen zehn und sechzig Prozent liegen.The strands 2,3,4 and 5 consist essentially of Aramid yarns 8 that are helical in a matrix Polyurethane are fixed. For stranding or turning the Aramid yarns 8 with a protective impregnating agent, treated with a polyurethane solution, for example. The share of Polyurethane on each strand 2,4,5 is decisive for the bending fatigue strength of the rope 1. The higher the proportion of Polyurethane, the higher the alternating bending power. With increasing polyurethane content decreases the fill factor of the whole Rope 1 and thus the load-bearing capacity and the elongation behavior of the rope 1. The polyurethane part for impregnating the strands 2,4,5 can, for example, depending on the desired rope properties are between ten and sixty percent.

Bei dem dargestellten Ausführungsbeispiel sind exemplarisch sieben Aramidgarne 8 mittels Imprägnierung zu einem Filament 7 verbunden und fixiert. Die Imprägnierung bildet dabei um jedes einzelne Filament 7 eine schützende dünne Schicht 9. Sieben der Filamente 7 sind miteinander schraubenlinienförmig zu einer Litze 2,3,4,5 geschlagen. In der tatsächlichen Ausbildung besitzen die Filamente 7 nicht die in der Zeichnung dargestellte kreisrunde Form, sondern sind an die Oberfläche benachbarter Filamente und der Litzen angepasst. Insoweit ist der Aufbau aller bei dem Ausführungsbeispiel verwendeter Litzen 2,3,4,5 grundsätzlich gleich, jedoch kann die Anzahl der Verdrehungen pro Meter zwischen den verschiedenen Litzenlagen und den Litzen mit verschiedenen Litzendurchmessern unterschiedlich sein.In the illustrated embodiment are exemplary seven aramid yarns 8 by impregnation into a filament 7 connected and fixed. The impregnation forms everything single filament 7 a protective thin layer 9. seven of the Filaments 7 are helical to one another Stranded 2,3,4,5 struck. In actual training the filaments 7 do not have those in the drawing shown circular shape, but are on the surface adjoining filaments and strands. So far the structure of all strands used in the embodiment 2,3,4,5 basically the same, but the number of Twists per meter between the different strands and the strands with different strand diameters be different.

Jede der in der Decklage 6 verseilten dicken Litzen 4 und dünnen Litzen 5 ist erfindungsgemäss von einer zusätzlichen Schutzschicht 10 aus Imprägniermittel umhüllt. Diese Schutzschicht wird vorteilhafterweise durch zusätzliches Tränken in einen Imprägniermittelbad im Durchlaufverfahren auf der Oberfläche der dicken Litzen 4 und dünnen Litzen 5 gebildet. Das Imprägniermittel enthält neben Polyurethan auch Zusätze von UV-Stabilisatoren, vorzugsweise Siliziumkristalle, Oxidations- und Reduktionsblocker. Durch die Zugabe von Kurzfasern, vorzugsweise aus Aramid, erhält die Schutzschicht 10 eine verbesserte Abriebfestigkeit.Each of the thick strands 4 and 4 stranded in the cover layer 6 thin strands 5 is according to the invention of an additional Protective layer 10 encased in impregnating agent. This Protective layer is advantageously by additional Soak in a impregnation bath in a continuous process the surface of the thick strands 4 and thin strands 5 educated. In addition to polyurethane, the impregnating agent also contains Additions of UV stabilizers, preferably silicon crystals, Oxidation and reduction blockers. By adding Short fibers, preferably made of aramid, maintain the protective layer 10 improved abrasion resistance.

Die Dicke 11 der Schutzschicht 10 um die einzelnen Litzen 4,5 beträgt hier 0,2 mm; erfindungsgemäss kann sie jedoch im Bereich zwischen 0,1 und 1 mm je nach gewünschter Schutzwirkung gewählt werden. Die Schutzschicht 10 wirkt als Abriebschutz zwischen den dicken Litzen 4 und den dünnen Litzen 5 der Decklage 6 und bildet im Verband aller Litzen 4,5 der Decklage 6 nach aussen eine ebenso wirkungsvolle wie kostengünstig herzustellende Umhüllung des Seils 1. Auf einen zusätzlichen Seilmantel aus Kunststoff kann deshalb verzichtet werden. Gemäss der Erfindung mit einer Schutzschicht 10 beschichtete Litzen 4, 5 können als Halberzeugnis vorgefertigt werden und dann je nach Bedarf mittels herkömmlichen Verseilmaschinen weiterverarbeitet werden, was die Herstellungskosten des Aramidfaserseil 1 bedeutend reduziert. Statt einem Imprägniermittel kann auch eine andere Flüssigkeit mit Hafteigenschaft auf das Seil aufgebracht werden. The thickness 11 of the protective layer 10 around the individual strands 4, 5 here is 0.2 mm; According to the invention, however, it can Range between 0.1 and 1 mm depending on the desired protective effect to get voted. The protective layer 10 acts as an abrasion protection between the thick strands 4 and the thin strands 5 of the Cover layer 6 and forms 4.5 of the cover layer in association with all strands 6 externally an effective as well as inexpensive Sheathing of the rope to be produced 1. On an additional Rope sheath made of plastic can therefore be dispensed with. Coated according to the invention with a protective layer 10 Strands 4, 5 can be prefabricated and semi-finished then as required using conventional stranding machines be further processed, which is the manufacturing cost of Aramid fiber rope 1 significantly reduced. Instead of one Impregnant can also be used with another liquid Adhesive property to be applied to the rope.

Neben Anwendungen als reines Tragseil, lässt sich das Seil bei verschiedensten Anlagen der Fördertechnik anwenden, z.B. für Aufzüge, Schachtförderanlagen im Bergbau, Lastkränen wie Bau-, Hallen- oder Schiffskräne, Seilbahnen und Skilifte sowie als Zugmittel bei Fahrtreppen. Der Antrieb kann sowohl durch Reibschluss über Treibscheiben oder Koeppe-Scheiben als auch durch drehende Seiltrommeln, auf die das Seil aufgewickelt wird, erfolgen. Unter Förderseil ist ein laufendes, angetriebenes Seil zu verstehen, das gelegentlich auch als Zug- oder Tragseil bezeichnet wird. In addition to applications as a pure suspension rope, the rope can also be used use a wide variety of conveyor systems, e.g. For Elevators, mine hoists in mining, load cranes such as construction, Hall or ship cranes, cable cars and ski lifts as well as Traction devices for escalators. The drive can both by Friction over traction sheaves or Koeppe sheaves as well by rotating rope drums on which the rope is wound will be done. Under conveyor rope is a running, to understand driven rope, sometimes as a pull or Carrier rope is called.
