Description

Die Erfindung betrifft eine Einrichtung zur Erkennung der Ablegereife bei Kunstfaserseilen für Aufzüge.The invention relates to a device for detecting the Maturity for synthetic fiber ropes for lifts.

Bis heute werden im Aufzugsbau Stahlseile verwendet, welche mit den Kabinen bzw. den Lastaufnahmemitteln und Gegengewichten verbunden sind. Diese laufenden Stahlseile sind nicht dauerfest. Durch schwellende Spannungen und unterstützt durch den Verschleiss treten in den Biegezonen nach und nach Drahtbrüche auf. Das Versagen tritt durch die Kombination der verschiedenen Beanspruchungen in Aufzugsseilen, geringe Zugspannungen, aber hohe Pressungen bei hohen Spielzahlen, auf. Im Aufzugsbau spricht man von einem kontrollierbaren Seilversagen. Dies bedeutet, dass aus dem äusseren Zerstörungsgrad des Seiles die gefahrlose Restnutzungsdauer ablesbar ist. Von der Zahl der Drahtbrüche und vor allem von der Zahl der äusseren Drahtbrüche kann nur bedingt auf die verbleibende Seilbruchkraft geschlossen werden. Innere Drahtbrüche bleiben unter Umständen unbemerkt. Aufgrund dessen wird die Ablegedrahtbruchzahl durch eine bestimmte Anzahl von Drahtbrüchen auf einem Seilabschnitt definiert. Der Prüfer zählt entsprechend die Anzahl der Drahtbrüche. Wird die Ablegereife des Drahtseiles an der Drahtbruchzahl rechtzeitig erkannt, bleibt im Normalfall eine ausreichende Restbruchkraft erhalten, die die auftretende Seilzugkraft übersteigt.Steel cables are still used in elevator construction today, which with the cabins or the load handling devices and Counterweights are connected. These running steel cables are not permanent. Through swelling tensions and supported by the wear occur in the Bending zones gradually break open. The Failure occurs through the combination of different Stress in elevator ropes, low tensile stress, but high pressures with high game numbers. in the Elevator construction is called controllable Rope failure. This means that from the outside Degree of destruction of the rope the safe Remaining service life can be read. From the number of Broken wires and especially on the number of outer ones Broken wires can only partially affect the remaining Rope breaking force must be closed. Internal wire breaks may go unnoticed. Because of that the number of wire breaks by a certain number of Broken wires defined on a section of rope. Of the The inspector counts the number of wire breaks accordingly. If the wire rope is ready to be discarded on the The number of wire breaks recognized in good time usually remains receive a sufficient residual breaking force that the occurring cable pulling force exceeds.

Ein Kunstfaserseil ist insofern nicht mit einem Stahlseil zu vergleichen. Aufgrund der Kunstfaserseilmachart kann das oben beschriebene Verfahren zur Bestimmung der Ablegereife nicht zur Beurteilung eines möglichen Verschleisszustandes eines Kunstfaserseiles genutzt werden. Der äussere Mantel des neuartigen Tragorganes verhindert die visuelle Erkennung von Faser- oder Litzenbrüchen.In this respect, a synthetic fiber rope is not a steel rope to compare. Due to the synthetic fiber rope style the method described above for determining the Discard maturity not for the assessment of a possible Wear condition of a synthetic fiber rope used become. The outer jacket of the new support element prevents the visual detection of fiber or Strand breaks.

Mit der GB-PS 2 152 088 ist ein Kunstfaserseil bekanntgeworden, bei dem eine oder mehrere elektrisch leitende Indikatorfasern in die Litzen eingelegt werden, um den Seilzustand zu überwachen. Die von den Kunstfasern umgebenen Kohle-Indikatorfasern und die Litze sollen die gleichen mechanischen Eigenschaften haben, so dass sie gleichzeitig versagen. Durch Anlegen einer Spannungsquelle an der Indikatorfaser kann ein Reissen der Faser detektiert werden. Auf diese Weise kann jede einzelne Litze eines Kunstfaserseil überprüft und bei Überschreiten einer gewissen Anzahl gerissener Litzen das Seil ausgewechselt werden.With GB-PS 2 152 088 is a synthetic fiber rope become known in which one or more electrically conductive indicator fibers are inserted into the strands, to monitor the rope condition. The synthetic fibers Surrounded carbon indicator fibers and the braid are said to have the same mechanical properties so that they fail at the same time. By creating one Voltage source on the indicator fiber can tear of the fiber can be detected. In this way, everyone single strand of a synthetic fiber rope checked and attached Exceeding a certain number of torn strands Rope to be replaced.

Bei der vorstehend beschriebenen Erfindung werden die Indikatorfasern so dimensioniert, dass sie gleichzeitig mit den tragenden Litzen reissen. Im Extremfall ist somit eine ausreichende Restbruchkraft schwierig zu erhalten, da der Riss einer Indikatorfaser das Versagen einer gesamten tragenden Litze bedeutet und nicht nur einer einzelnen Faser einer Litze. Die Zeitspanne zwischen einem scheinbar intakten Seil und einer notwendigen Auswechslung des Seils ist aufgrund dieser Methode sehr klein. Der Verschleissfortschritt ist somit nicht erkennbar. Diese Einrichtung kann den Sicherheitsanforderungen im Aufzugsbau nicht genügen. Desweitern ist eine Durchmesserreduzierung des Kunstfaserseils, bzw. eine Abnutzung des Mantels, auch nach einer grossen Anzahl Biegewechsel optisch nicht zu erkennen.In the invention described above, the Indicator fibers dimensioned so that they are simultaneously tear with the carrying strands. So in the extreme case it is difficult to obtain sufficient residual breaking strength because the tear of an indicator fiber is the failure of one entire stranded wire means and not just one single fiber of a strand. The period between an apparently intact rope and a necessary one Changing the rope is very much due to this method small. The wear progress is therefore not recognizable. This facility can Safety requirements in elevator construction are not sufficient. Furthermore, the diameter is reduced Synthetic fiber rope, or wear of the sheath, too optically not after a large number of bending changes detect.

Der Erfindung liegt die Aufgabe zugrunde, eine Ablegereifeerkennung für ein Kunstfaserseil für Aufzüge der eingangs genannten Art vorzuschlagen, welche die vorgenannten Nachteile nicht aufweist und mittels welcher eine Auswechslung der Seile zuverlässig rechtzeitig, jedoch nicht unnötig vorzeitig erfolgen kann.The invention has for its object a Discard maturity detection for a synthetic fiber rope for lifts of the type mentioned at the beginning, which the does not have the aforementioned disadvantages and by means of which a replacement of the ropes reliably in time, but cannot be done prematurely unnecessarily.

Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichnete Erfindung gelöst.This object is achieved by the in claim 1 characterized invention solved.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass durch unterschiedliche Eigenschaften der leitenden Indikatorfasern und der tragenden Fasern eine genaue Beurteilung der Restbruchkraft des Kunstfaserseils möglich ist.The advantages achieved by the invention are in essential to see that through different Properties of the conductive indicator fibers and the bearing fibers an accurate assessment of the Residual breaking strength of the synthetic fiber rope is possible.

Durch die in den Unteransprüchen aufgeführten Massnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Ablegereifeerkennung für Kunstfaserseile möglich. Jede Litzenlage des Kunstfaserseils besitzt vorzugsweise mehr als eine Indikatorfaser, damit eine Zufälligkeit in der Beurteilung des Seilzustandes ausgeschlossen ist. Den mit den Fasern zu Litzen verdrehten bzw. verzwirnten Kohle-Indikatorfasern kann pro Lage je eine Farbe zugeteilt werden um ein Anschliessen an eine Spannungsquelle zu vereinfachen. Indikatorfasern in mindestens jeder Litzenlage ermöglichen eine vorausschauende Abschätzung des Ablegezeitpunktes. Mittels einer mit den Indikatorfasern in Verbindung stehenden Inspektionssteuerung findet in bestimmten Intervallen eine selbsttätige Überprüfung des Seiles statt. Bei einer Grenzwertüberschreitung wird der Aufzug automatisch zu einer bestimmten Haltestelle gefahren und abgeschaltet. Zudem kann das Seil mit einem zweischichtigen, verschiedenfarbigen Seilmantel ausgestattet werden, so dass der Verschleissgrad des Seiles auf einfache Art und Weise optisch überprüft werden kann. By the measures listed in the subclaims are advantageous developments and improvements of discard maturity detection for Synthetic fiber ropes possible. Every strand of the Synthetic fiber rope preferably has more than one Indicator fiber, so a randomness in the Assessment of the condition of the rope is excluded. The one with the fiber twisted or twisted carbon indicator fibers can be assigned one color per layer are to be connected to a voltage source simplify. Indicator fibers in at least everyone Strand position enables a predictive assessment the time of filing. By means of a Indicator fibers related Inspection control takes place at certain intervals the rope is checked automatically. At a The elevator automatically closes when the limit value is exceeded drove to a certain stop and switched off. In addition, the rope can be covered with a two-layer different colored rope sheath can be equipped so that the degree of wear of the rope in a simple way can be checked visually.

Eine in einem Aufzugsschacht 1 geführte Kabine 2 wird von einem Antriebsmotor 3 mit einer Treibscheibe 4 über ein Kunstfaserseil 5 angetrieben. Am anderen Ende des Seiles 5 hängt ein Gegengewicht 6 als Ausgleichsorgan. Die Befestigung des Seils 5 an der Kabine 2 und am Gegengewicht 6 erfolgt über Seilendverbindungen 7. Der Reibwert zwischen dem Seil 5 und der Treibscheibe 4 wird so dimensioniert, dass bei auf einem Puffer 8 aufgesetztem Gegengewicht 6 eine weitere Förderung der Kabine 2 verhindert wird.1 shows a schematic representation of a Elevator system. One guided in an elevator shaft 1 Cabin 2 is powered by a drive motor 3 Traction sheave 4 driven by a synthetic fiber rope 5. At the other end of the rope 5 hangs a counterweight 6 as Compensation body. The attachment of the rope 5 to the Cabin 2 and on counterweight 6 takes place over Rope end connections 7. The coefficient of friction between the rope 5 and the traction sheave 4 is dimensioned so that at a counterweight 6 placed on a buffer 8 further promotion of the cabin 2 is prevented.

Fig.2 und Fig.3 zeigen ein Kunstfaserseil 5 mit Indikatorfasern. Das gezeigte, in Gegenschlagausführung aufgebaute Kunstfaserseil 5 ist dreilagig. Ein Seilmantel 12 umgibt eine äusserste Litzenlage 13. Zwischen einer mittleren Litzenlage 14 und der äussersten Litzenlage 13 wird ein reibungsmindernder Stützmantel 15 angebracht. Dann folgen eine innere Litzenlage 16 und eine Seilseele 17. Die Litzen 18 werden aus einzelnen Aramidfasern verdreht bzw. verzwirnt. Jede einzelne Litze 18 wird zum Schutz der Aramidfasern mit einem Imprägniermittel, z.B. Polyurethanlösung, behandelt. Das Prinzip der Ablegereifeerkennung basiert auf der Zusammenführung zweier Fasertypen mit verschiedenen Eigenschaften zu einer Litze 18. Die eine Faser, das Aramid, besitzt eine hohe Biegewechselfähigkeit und eine hohe spezifische Dehnung. Die andere Faser, eine Kohlefaser 19, hat ein spröderes Verhalten, also eine weniger gute Biegewechselfähigkeit und eine niedrigere Bruchdehnung als die Aramidfasern. Diese Werte der Kohle-Indikatorfasern 19 können je nach Anwendung bei 30% - 75% der Werte von Aramidfasern liegen. Entsprechend der im Seil 5 auftretenden verschiedenen Seilzugspannungen werden Kohle-Indikatorfasern 19 mit verschiedenen Bruchdehnungen im Seil 5 positioniert. Aufgrund der Seilmachart nimmt die Litzenlänge zur Seele 17 des Seiles 5 hin ab, so dass im laufenden Betrieb die inneren Litzen die geringste Dehnung aufweisen werden. Der Dehnung entsprechend werden für die Indikatoren 19 leitfähige Fasern mit zur Seilseele 17 hin geringer werdenden Bruchdehnungen verwendet. Mit Hilfe einer Spannungsquelle kann die Anzahl der gerissenen Kohle-Indikatorfasern 19 bestimmt werden.2 and 3 show a synthetic fiber rope 5 with Indicator fibers. The shown, in counterblow execution assembled synthetic fiber rope 5 is three layers. A Rope sheath 12 surrounds an outermost strand layer 13. Between a middle strand layer 14 and the outermost one Strand layer 13 becomes a friction-reducing support jacket 15 appropriate. Then an inner strand layer 16 and a rope core 17. The strands 18 are made of individual Aramid fibers twisted or twisted. Every single strand 18 is used to protect the aramid fibers with a Impregnating agents, e.g. Treated polyurethane solution. The The principle of discard maturity is based on the Merging two types of fibers with different ones Properties to a strand 18. The one fiber, the Aramid, has a high ability to change bends and a high specific elongation. The other fiber, one Carbon fiber 19 has a more brittle behavior, i.e. one less good bending ability and a lower one Elongation at break than the aramid fibers. These values of the carbon indicator fibers 19 can be 30% - 75% depending on the application the values of aramid fibers. According to the im Rope 5 occurring different cable tension are carbon indicator fibers 19 with different Elongation at break positioned in rope 5. Due to the Seilmachart takes the strand length to the core 17 of the rope 5 down, so that the inner strands during operation will have the least stretch. The stretch Accordingly, 19 become conductive for the indicators Fibers with decreasing towards the rope core 17 Elongation at break used. With the help of a voltage source the number of broken carbon indicator fibers 19 be determined.

Fig.4 zeigt eine Litze 18 eines Kunstfaserseils 5 mit einer Kohle-Indikatorfaser 19. Beide Fasertypen, Aramidfasern 20 und die Kohlefaser 19, werden bei der Litzenherstellung parallel angeordnet und miteinander verdreht bzw. verzwirnt. Dabei kann die Kohlefaser 19 auch genau mittig in der Litze 18 plaziert werden, oder auf der Mantellinie wendelförmig verlaufen. Die Kohlefaser 19 sollte innerhalb des Imprägniermittels angeordnet werden, damit ein ausreichender Schutz gegen Pressung und Reibung gegeben ist. Ansonsten ist ein vorzeitiges Versagen der Kohle-Indikatorfaser 19 zu erwarten und das Seil 5 erscheint fälschlicherweise ablegereif. Im laufenden Betrieb wird in jedem Falle die Kohle-Indikatorfaser 19 entweder aufgrund zu grosser Dehnungen oder einer zu grossen Anzahl von Biegewechseln eher reissen oder brechen als die Aramidfasern 20 einer Litze 18, welche sich durch aussergewöhnlich gute dynamische Eigenschaften auszeichnet.4 shows a strand 18 of a synthetic fiber rope 5 with a carbon indicator fiber 19. Both types of fibers, Aramid fibers 20 and carbon fiber 19 are used in the Strand production arranged in parallel and with each other twisted or twisted. The carbon fiber 19 also be placed exactly in the middle of the strand 18, or run helically on the surface line. The Carbon fiber 19 should be within the impregnating agent be arranged to provide adequate protection against Pressure and friction is given. Otherwise, is a premature failure of the carbon indicator fiber 19 too expect and the rope 5 appears incorrectly ready for discard. In ongoing operation, the Carbon indicator fiber 19 either due to too large Stretching or too many bending cycles more likely to tear or break than the aramid fibers 20 one Strand 18, which is characterized by exceptionally good characterized dynamic properties.

Ausschlaggebend für diese Ablegereifeerkennung ist die gute elektrische Leitfähigkeit der Kohle-Indikatorfasern 19. Die Indikatorfaser 19 wird in jeder Litzenlage 13, 14, 16 oder in der äussersten und innersten Litzenlage 13, 16 mindestens in zwei Litzen 18 plaziert. In wenigen Fällen reicht auch nur eine Indikatorfaser 19 in den einzelnen Litzenlagen 13, 14, 16 aus. Bei 1:1 gehängten Aufzügen werden immer zwei Indikatorfasern 19 einer Litzenlage 13, 14, 16 auf dem Gegengewicht 6 durch Verbindungselemente 22 miteinander verbunden bzw. in Reihe geschaltet. Bei 2:1 gehängten Anlagen kann dieser Vorgang im Maschinenraum durchgeführt werden. Die Indikatorfasern 19 werden aus dem Verbund des aus der Seilendbefestigung 7 geführten Seilendes herausgelöst und immer paarweise miteinander verbunden. Auf der Kabine 2 werden die Seilenden ebenfalls aus der Seilendverbindung 7 herausgeführt und die Indikatorfasern 19 aus dem Seilverbund gelöst. Dort werden die zusammengehörigen Kohle-Indikatorfasern 19 mittels Durchgangsmessung herausgesucht und mit gekennzeichneten elektrischen Leitungen verbunden. Diese Leitungen führen auf der Kabine 2 in eine Inspektionssteuerung. Um den Anschluss an die Inspektionssteuerung zu vereinfachen, werden den einzelnen Litzenlagen 13, 14, 16 verschiedene Farben zugeordnet. In der Inspektionssteuerung befinden sich alle notwendigen elektronischen Bauteile, die eine ständige Prüfung des Kunstfaserseiles 5 ermöglichen.5 shows a contacting of the carbon indicator fibers 19 at one end of a rope 5. Crucial for this maturity detection is the good electrical one Conductivity of the carbon indicator fibers 19. The Indicator fiber 19 is in each strand layer 13, 14, 16 or in the outermost and innermost strand layer 13, 16 placed in at least two strands 18. In a few cases only one indicator fiber 19 is sufficient in each Strand layers 13, 14, 16 from. With 1: 1 suspended lifts are always two indicator fibers 19 of a strand 13, 14, 16 on the counterweight 6 by connecting elements 22 connected together or connected in series. At This process can be hung in 2: 1 attachments Engine room to be carried out. The indicator fibers 19 are from the composite of the rope end attachment 7th led out rope end and always in pairs connected with each other. On the cabin 2 Rope ends also from the rope end connection 7 led out and the indicator fibers 19 from the Rope assembly released. There they belong together Carbon indicator fibers 19 by means of continuity measurement picked out and marked with electrical Lines connected. These lines run on the Cabin 2 in an inspection control. To the connection to simplify inspection control will individual strands 13, 14, 16 different colors assigned. In the inspection control are all necessary electronic components, one enable constant testing of the synthetic fiber rope 5.

Fig.6 zeigt ein Schaltschema der Inspektionssteuerung. Über eine Spannungsquelle 25 wird ein konstanter Strom Ik in die zum Gegengewicht 6 laufende Indikatorfaser 19 eingespeist. Die Kohle-Indikatorfaser 19 stellt einen Widerstand R dar. Ein Tiefpassfilter TP filtert die ankommenden Impulse und führt diese einem Schwellwertschalter SW zu. Der Schwellwertschalter SW vergleicht die gemessenen Spannungen. Bei Überschreitung spezifischer Grenzwerte, d.h. aufgrund der reissenden Indikatorfasern 19 wird der Widerstand so gross, dass der zulässige Spannungswert überschritten wird. Diese Überschreitung des Grenzwertes wird von einem nicht flüchtigen Speicher M gespeichert. Dieser Speicher M kann mittels einer Reset-Taste T gelöscht werden oder er gibt seine Informationen an eine auf der Kabine 2 befindliche Logik L weiter. Diese Logik L wird von der Aufzugssteuerung selbsttätig abgefragt. Jede Indikatorpaarung wird entsprechend der obengenannten Anordnung verkabelt und ständig überprüft. Die Aufzugssteuerung überprüft dauernd die Logik und schaltet den Aufzug ab, wenn zu viele Faserrisse von der Logik übermittelt werden.Fig. 6 shows a circuit diagram of the inspection control. A constant current Ik into the indicator fiber 19 running towards the counterweight 6 fed. The carbon indicator fiber 19 represents one Resistor R. A low-pass filter TP filters the incoming impulses and leads them to you Threshold switch SW closed. The SW threshold switch compares the measured voltages. If exceeded specific limit values, i.e. due to the tearing The indicator fibers 19 the resistance becomes so great that the permissible voltage value is exceeded. This One does not exceed the limit volatile memory M stored. This memory M can be deleted by means of a reset button T or there his information to someone on the cabin 2 Logic L further. This logic L is from the Elevator control queried automatically. Each Indicator pairing is made according to the above Arrangement wired and constantly checked. The Elevator control continuously checks the logic and switches the elevator off if too many fiber tears from the logic be transmitted.

Damit eine bestimmte Resttragfähigkeit des Seiles 5 gewährleistet werden kann, darf nur ein bestimmter Prozentsatz der Indikatorfasern 19 versagen. Dieser Wert kann, in Abhängigkeit der Dimensionierung der Kohle-Indikatorfasern 19, zwischen 20% und 80% liegen, bezogen auf alle Kohle-Indikatorfasern 19. Dann wird der Aufzug selbsttätig in einen vorbestimmten Halt gefahren und ausgeschaltet. Störungsmeldungen können über ein Display weitergegeben und angezeigt werden. Der Verschleisszustand kann über ein Modem von jedem beliebigen Ort aus abgefragt werden. So that a certain residual load capacity of the rope 5 only a certain one can be guaranteed Percentage of indicator fibers 19 fail. This value can, depending on the dimensioning of the carbon indicator fibers 19, are between 20% and 80% on all carbon indicator fibers 19. Then the elevator automatically moved into a predetermined stop and switched off. Malfunction reports can be made on a display passed on and displayed. Of the Wear status can be checked by anyone via a modem can be queried from any location.

Diese Ablegereifeerkennung ermöglicht auch die Prüfung von Litzen 18, die in der mittleren oder innersten Litzenlage 14, 16 des Seiles 5 angeordnet sind, ohne das eine visuelle Beurteilung oder eine induktive Prüfung notwendig wäre. Damit den verschiedenen mechanischen Spannungszuständen in den Litzenlagen 13, 14, 16 im Kunstfaserseil 5 Rechnung getragen werden kann, werden den einzelnen Lagen 13, 14, 16 Kohle-Indikatorfasern 19 mit entsprechenden Bruchdehnungen zugeordnet. Den äussersten Indikatorfasern 19, die neben den Pressungen die höchsten Schubbelastungen ertragen müssen, können Indikatorfasern 19 mit einer etwas höheren Bruchdehnung zugeordnet werden. Auf diesem Weg kann eine optimal gesteuerte Seilverschleisskontrolle gewährleistet werden.This maturity detection also enables testing of strands 18 that are in the middle or innermost Strand layer 14, 16 of the rope 5 are arranged without the a visual assessment or an inductive test would be necessary. So that the different mechanical Tension states in the strand layers 13, 14, 16 in Synthetic fiber rope 5 can be taken into account the individual layers 13, 14, 16 carbon indicator fibers 19 associated with corresponding elongations at break. The outermost indicator fibers 19 in addition to the pressings can withstand the highest shear loads Indicator fibers 19 with a somewhat higher elongation at break be assigned. In this way, an optimal controlled rope wear control can be guaranteed.

Fig.7 zeigt ein Kunstfaserseil 5 im Querschnitt, mit mehrfarbigem Mantel. Für die visuelle Beurteilung eines Kunstfaserseils 5 auf einen möglichen ablegereifen Verschleisszustand wird die vorhandene Seilmanteloberfläche überprüft. Dafür muss gewährleistet werden können, dass ein Abrieb des Seilmantels 12 an der Oberfläche erfolgt. Dieser Abrieb wird über den im laufenden Betrieb auftretenden Schlupf erzeugt. Der Schlupf stellt das Mass für die Relativbewegung zwischen Seil 5 und Treibscheibe 4 dar. Er ist definiert als die Differenz der Geschwindigkeiten von Seil 5 und Treibscheibe 4 bezogen auf die Seilgeschwindigkeit. Hat ein Seil 5 beim Auflaufen auf die Treibscheibe 4 nicht deren Geschwindigkeit, spricht man von Gleitschlupf. Wenn beim Lauf über die Treibscheibe 4 die an beiden Seiten hängenden Gewichte unterschiedliche Seilzugkräfte verursachen, wird in jedem Fall Dehnschlupf auftreten, auch wenn die Treibfähigkeit überaus gross wäre. Das Seil 5 hat bei unterschiedlichen Seilzugkräften vor und hinter der Treibscheibe 4 verschiedene Spannungen. Dadurch werden verschiedene Dehnungen vor und hinter der Treibscheibe 4 erzeugt. Beim Lauf über die Treibscheibe 4 stellt sich der neue Dehnungszustand durch Rutschen des Seiles 5 ein. Bei kleinem Seilkraftverhältnis tritt die daraus resultierende Rutschbewegung im Bereich des Ablaufpunktes auf, bei voll ausgeschöpfter Treibfähigkeit tritt dagegen ein Rutschen über den gesamten Umschlingungsbogen auf.7 shows a synthetic fiber rope 5 in cross section, with multicolored coat. For the visual assessment of a Synthetic fiber rope 5 to a possible tire The existing condition becomes worn Rope jacket surface checked. This must be guaranteed can be that an abrasion of the cable sheath 12 on the Surface takes place. This abrasion is over the in slip occurring during operation. Of the Slip sets the measure for the relative movement between Rope 5 and traction sheave 4. It is defined as the Difference in speeds of rope 5 and Traction sheave 4 based on the rope speed. Has a rope 5 when running onto the traction sheave 4 is not their speed, one speaks of sliding slip. If when running over the traction sheave 4 on both sides hanging weights different cable tensile forces cause expansion slip will occur in any case, even if the driving ability were extremely high. The rope 5 has different pulling forces in front and behind the traction sheave 4 different voltages. Thereby are different strains in front of and behind the Traction sheave 4 generated. When running over the traction sheave 4 the new state of stretching arises when the Rope 5 a. With a small rope force ratio, the resulting sliding movement in the area of the Point of expiry on, with fully exhausted driving ability on the other hand, there is a slide across the entire Wrap on.

Das Seil 5 gleitet immer auf der Treibscheibe 4 in Richtung der grösseren Seilzugkraft, unabhängig von der Drehrichtung der Treibscheibe 4. Die Grössenordnung des Dehnschlupfes wächst entsprechend der Treibfähigkeit des Seilmantels 12 und der Rillengeometrie der Treibscheibe 4.The rope 5 always slides on the traction sheave 4 in Direction of the greater rope pull, regardless of the Direction of rotation of the traction sheave 4. The order of magnitude of the Elongation slip increases according to the driving ability of the Rope sheath 12 and the groove geometry of the traction sheave 4th

Der Seilmantel 12 soll eine der Litzenstruktur entsprechende Oberfläche erhalten. Die Oberfläche des Seilmantels 12 kann als Berg-/Talstruktur bezeichnet werden. Aufgrund der Materialkombination des Kunstfaserseils 5 und der Guss-/Stahltreibscheibe 4 unterliegt diese keinem abrasiven Verschleiss mehr, so dass im Prinzip von einer definierten Lauffläche 30 gesprochen werden kann. Allfällige Flüssigkeiten auf der Treibscheibe 4 können aufgrund der Berg-/Talstruktur des Seilmantels 12 von der definierten Lauffläche verdrängt werden. Die grössten Pressungen, die auf die ummantelten Litzen 18 wirken, werden im Rillengrund 31 der Treibscheibe 4 auf die Bergbereiche 32 des Seiles 5 ausgeübt. Folglich werden dort die grössten Verschleisserscheinungen zu erkennen sein. Vor allem durch den Dehnschlupf, aber auch in einem gewissem Masse durch den Gleitschlupf, wird der Oberflächenverschleiss erzeugt. Aus Erfahrungen mit den Stahlseilen werden die grössten Veränderungen auf den Beschleunigungsstrecken zu verzeichnen sein. Damit der Betrag des Abriebes festgestellt, d.h. dem Prüfer ein Mittel zur visuellen Kontrolle zur Verfügung gestellt werden kann, ob bis zur nächsten Prüfung genügend Manteldicke vorhanden ist, wird der Seilmantel 12 in einer inneren 33 und einer äusseren Farbe 34 extrudiert. Die Dicke der seilinneren Extrusion, d.h. die zweite Farbe 33 misst eine spezifische Stärke, die noch ein genügend grosses Laufvermögen garantiert. Der Mantel 12 schützt die Litzen 18 und erzeugt die notwendige Traktionsfähigkeit. Erkennt der Prüfer bei einer visuellen Kontrolle die einextrudierte zweite Farbe 33 des Seilmantels 12, so weiss er, dass das Seil 5 in absehbarer Zeit ersetzt werden muss.The cable sheath 12 should be one of the strand structure get appropriate surface. The surface of the Rope sheath 12 can be referred to as a mountain / valley structure become. Due to the material combination of the Synthetic fiber rope 5 and the cast / steel drive pulley 4 this is no longer subject to abrasive wear, so that in principle from a defined tread 30 can be spoken. Any liquids on the Traction sheave 4 can due to the mountain / valley structure Rope sheath 12 displaced from the defined tread become. The largest pressings on the jacketed Strands 18 act in the groove base 31 of the Traction sheave 4 on the mountain areas 32 of the rope 5 exercised. As a result, the largest are there Signs of wear can be recognized. Especially due to the expansion slip, but also to a certain extent due to the slip, the surface wear generated. Experience with the steel cables turns them into biggest changes on the acceleration routes be recorded. So the amount of abrasion determined, i.e. the auditor a means of visual Control can be made available up to the next test, there is sufficient sheath thickness the cable sheath 12 in an inner 33 and an outer Color 34 extruded. The thickness of the inner rope extrusion, i.e. the second color 33 measures a specific strength, which still guarantees a sufficiently large running ability. The jacket 12 protects the strands 18 and generates the necessary traction ability. The examiner recognizes at a visual inspection the extruded second color 33 of the rope sheath 12, he knows that the rope 5 in foreseeable future needs to be replaced.

Zur optimalen Beurteilung des Seilzustandes eines Kunstfaserseiles sollte eine Kombination der beiden Prüfverfahren, die Selbstkontrolle mittels Indikatorfasern 19 und die visuelle Seilmantelkontrolle mit einem zweifarbigen Mantel, angewendet werden.For optimal assessment of the rope condition of a Synthetic fiber rope should be a combination of the two Test methods, self-control by means of Indicator fibers 19 and the visual rope sheath control with a two-tone coat.
