Abstract

A rope is made of synthetic non-conducting strands with interspersed electrically conducting indicator fibers to warn of breaks or faults. All the indicator fibers are connected together at one end and selectively connected in series and parallel at the other. Any breaks are detected electrically by comparison with a reference value for electrical resistance. Independent claims are also included for: (a) a contact element fitted at one end of the rope, e.g. a disk with a cutting edge held by a self-tapping screw or a number of alternative contact devices (b) a plastic rope fitted with safety wires connected in this manner; (c) twinned ropes of opposite twist fitted with safety wires and a joint contact device.

Seilmantel befreit und die Indikatorfasern freigelegt. Daraufhin werden Indikatorfasern elektrisch in Reihe verschaltet, indem freiliegende Indikatorfasern eines Kunstfaserseilendes mittels einzelnen Verbindungselementen paarweise miteinanderverbunden werden. Die hohe Anzahl der in jedem Kunstfaserseil eingebrachten Indikatorfaseren macht diese Konfektionierung teuer.Cable sheath freed and the indicator fibers exposed. Thereupon indicator fibers become electrically in series interconnected by exposing an indicator fiber Synthetic fiber rope ends using individual connecting elements connected in pairs. The high number of indicator fibers incorporated in each synthetic fiber rope this packaging is expensive.

Das Verfahren und die zur Durchführung des Verfahrens verwendeten Werkstücke sollen mit bestehenden Standards des Aufzugsbaus kompatibel sein.The object of the present invention is a method for Contacting those that can be monitored in terms of security To provide synthetic ropes that are inexpensive and is reliable.

    Die Indikatorfasern 9 sind elektrisch verschaltet, um so das Reissen von Indikatorfasern 9 elektrisch zu messen. Indikatorfasern 9 sind an einem Seilende mittels einer weiter unten näher beschriebenen Kontaktiereinrichtung 1,2,3,4,5,51 in Reihe verschaltet bzw. kurzgeschlossen. Jede dieser Indikatorfasern 9, bzw. jede Indikatorfaserschaltung besitzt einen elektrischen Widerstand, über den an dem nicht kurzgeschlossenen Seilende beispielsweise über das Ende einer beliebig wählbaren Indikatorfaser 9 bzw. Indikatorfaserschaltung eine elektrische Spannung angelegt wird und die übrigen Indikatorfasern sequenziell oder permanent mittels beispielsweise der aus der EP-0,731,209 bekannten Überwachungseinrichtung auf Leitfähigkeit bzw. Grösse des Widerstands überprüft werden. Bei Reissen einer Indikatorfaser 9 bzw. Indikatorfaserschaltung bricht eine daran angelegte elektrische Spannung zusammen, was erfasst und an eine Überwachung weitergeleitet wird. Übersteigt die Anzahl gerissener Indikatorfasern 9 einen vorgegebenen Wert, gibt die Überwachung beispielsweise ein Alarmsignal. Fällt die speisende Indikatorfaser 9 aus, springt die Speisung automatisch auf eine der übrigen leitenden Indikatorfasern 9 über. Dem Fachmann steht es bei Kenntnis der vorliegenden Erfindung frei, Indikatorfasern in anderen Indikatorfaserschaltungen, beispielsweise in Kombinationen von Reihen- und Parallelschaltungen zu realisieren. Vorteilhafterweise wird die elektrische Spannung, wie zuvor beschrieben, am ersten Ende eines Litzenseils 6 angelegt und auch gemessen. Dazu bildet die Kontaktierungseinrichtung 1,2,3,4,5,51 am zweiten Endes des Kunstfaserseils 6 eine elektrisch leitende Verbindung von mehr als zwei Indikatorfasern. Die Kontaktiereinrichtung 1,2,3,4,5 ist aus beliebigen, elektrisch isolierenden, bzw. elektrisch leitenden Materialien hergestellt. In Bereichen, wo sie auf elektrisch miteinander zu kontaktierenden Indikatorfaserenden 9 zu liegen kommt, ist sie elektrisch leitend. Im Unterschied dazu bestimmen die Materialien der Kontaktiereinrichtung 51 massgeblich deren Eigenschaften, was unten anhand der Figur 6 beschrieben ist.The indicator fibers 9 are electrically connected, so that Measure the tearing of indicator fibers 9 electrically. Indicator fibers 9 are attached to a rope end by means of a contacting device described in more detail below 1,2,3,4,5,51 connected in series or short-circuited.

    Erfindungswesentlich bei allen diesen Ausführungsformen der Kontaktierungseinrichtungen ist, dass nicht einzelne Indikatorfasern gezielt einander zugeordnet und untereinander kontaktiert werden, sondern eine möglichst grosse Anzahl von Indikatorfasern mit dem elektrisch leitenden Teil einer einzigen Kontaktierungseinrichtung in Berührung kommen und wahllos kurzgeschlossen werden. Die gebildete Verbindung wird vor Aufnahme des Überwachungseinsatzes messtechnisch ausgemessen und daraus ein Referenzzustand des sicherheitstechnisch überwachbaren Seils definiert. Beispielsweise werden ausgehend von einer beliebig gewählten speisenden Indikatorfaser die Leitfähigkeit der übrigen Indikatorfasern ermittelt, d.h. es wird getestet, welche Indikatorfasern mit der speisenden Faser in Verbindung stehen. Das Ergebnis der Referenzmessung wird in der Überwachungseinrichtung gespeichert und legt diejenigen Indikatorfasern fest, welche zur Seilüberwachung verwendet werden. Anstatt einzelne Indikatorfasern auszutesten, kann wiederum ausgehend von einer speisenden Indikatorlitze der Gesamtwiderstand aller mittels Kontakteinrichtung kurzgeschlossener Indikatorfasern des Seils gesamthaft gemessen und gespeichert werden. Abweichungen von diesem Referenzwert während der Ablegereifeüberwachung werden als gerissene Indikatorfasern interpretiert. Essential to the invention in all of these embodiments of the Contacting facilities is that not individual Indicator fibers specifically assigned to each other and be contacted with each other, but one if possible large number of indicator fibers with the electrical conductive part of a single contacting device in Come into contact and are short-circuited indiscriminately. The formed connection is before the inclusion of the Monitoring operation measured and from it a reference state of the safety-technically monitorable Seils defined. For example, starting from a arbitrarily chosen feeding indicator fiber the Conductivity of the other indicator fibers determined, i.e. it it is tested which indicator fibers with the feeding Fiber related. The result of the reference measurement is stored and stored in the monitoring device those indicator fibers that are used for rope monitoring be used. Instead of individual indicator fibers to test, can in turn start from a dining Indicator wire the total resistance of all means Contact device of short-circuited indicator fibers of the Seils are measured and saved overall. Deviations from this reference value during the Discard maturity monitoring are called torn indicator fibers interpreted.

Eine Spannhülse 23 ist koaxial über das freie Ende des Kunstfaserseils 6 geschoben und mit Hilfe einer Gewindemuffe 24 und einer Überwurfbüchse 25 fixiert. Die Spannhülse 23 weist am Umfang einen Bund 26 auf, der in Längsrichtung der Spannhülse 23 einen Axialanschlag 27 ausbildet. Die Spannhülse 23 weist bis hin zum Axialanschlag 27 in Längsrichtung, z.B. wie hier gezeigt, drei Schlitze 28 auf. Auf das geschlitzte Spannhülsenstück 29 sind koaxial ein erster Spannring 30 und ein zweiter Spannring 31 aufgeschoben, welche einander zugewandt komplementäre Kegelflächen 32,33 ausbilden. Der erste Spannring 30 ist in Längsrichtung geschlitzt und deshalb in radialer Richtung elastisch. Der erste Spannring 30 stützt sich am Axialanschlag 27 ab, während der zweite Spannring 31 bei axial aufgeschobener Gewindemuffe 24 mittels einer darin ausgebildeten Axialschulter 27 gegen den ersten Spannring 30 gekontert wird, wodurch mit Hilfe der aufeinander auflaufenden Kegelflächen 32,33 axial gerichtete Kräfte eine zentrische wirkende Kraftkomponente auf den geschlitzten ersten Spannring ausüben und das geschlitzte Spannhülsenstück 29 auf das Kunstfaserseil 6 spannt. Die Gewindemuffe 24 bildet einen rohrförmigen Gewindestutzen 34 mit Aussengewinde 35 aus, der wie hier dargestellt, beispielsweise für ein einfacheres Lösen der Kontaktiereinrichtung 3 mit einem Schlüsselkopf 36 zum Ansetzen eines Gabelschlüssels, einer Zange oder dergleichen, versehen ist.A contacting device 3, such as that, is without a tool is shown in Figure 3, at the free end of the Form synthetic fiber rope 6. An adapter sleeve 23 is pushed coaxially over the free end of the synthetic fiber rope 6 and with the help of a threaded sleeve 24 and a union sleeve 25 fixed. The clamping sleeve 23 has a collar 26 on the circumference on the one in the longitudinal direction of the clamping sleeve 23 Forms axial stop 27. The clamping sleeve 23 points up to the axial stop 27 in the longitudinal direction, e.g. like here shown, three slots 28 on. On the slotted one Collet piece 29 are coaxially a first clamping ring 30 and a second clamping ring 31 slid on each other Form complementary conical surfaces 32, 33 facing. The first clamping ring 30 is slotted in the longitudinal direction and therefore elastic in the radial direction. The first tension ring 30 is supported on the axial stop 27, while the second Clamping ring 31 with threaded sleeve 24 axially pushed on by means of an axial shoulder 27 formed therein against the first clamping ring 30 is countered, whereby with the help of axially directed conical surfaces 32,33 converging Forces a centric force component on the exercise the slotted first clamping ring and the slotted one Clamping sleeve piece 29 clamps on the synthetic fiber rope 6.

    Figur 4 zeigt eine Kontaktiereinrichtung 4 in Form einer selbstschneidenden Kurzschlussmuffe 40 mit einem Rohrstutzen 41 in dessen Innenwandung ein Innengewinde 42 geschnitten ist. Am Aussenumfang des Rohrstutzens 41 ist ein Schlüsselkopf 43 ausgebildet, der zum Ansetzen eines Werkzeugs bei der Montage der Kurzschlussmuffe 40 auf das freie Ende des Kunstfaserseils 6 dient. Der Innendurchmesser des Innengewindes 42 ist kleiner gewählt als der Durchmesser des Kunstfaserseils 6 ohne Seilmantel 12, während der Aussendurchmesser des Innengewindes 42 in etwa dem Aussendurchmesser des Kunstfaserseils 6 einschliesslich Seilmantel 12 entspricht. Zur Herstellung der Kontaktierung wird das offene Ende des Rohrstutzens 41 axial auf das freie Ende des Kunstfaserseils 6 aufgesezt und durch Drehen der Kurzschlussmuffe 40 um deren Längsachse auf das Seilende aufgeschraubt. Infolge der Drehbewegung schneidet das Innengewinde 42 sich in den Seilmantel 12, wobei die Kurzschlussmuffe 40 mit der äussersten Litzenlage und den darin verlaufenden Indikatorfasern 9 in Kontakt kommt und diese kurzschliesst.Figure 4 shows a contacting device 4 in the form of a self-tapping short-circuit sleeve 40 with a pipe socket 41 cut an internal thread 42 in its inner wall is. On the outer circumference of the pipe socket 41 is a Key head 43 formed to attach a Tool when assembling the short-circuit sleeve 40 on the free end of the synthetic fiber rope 6 is used. The inside diameter of the internal thread 42 is chosen to be smaller than the diameter of the synthetic fiber rope 6 without rope sheath 12, during the Outside diameter of the internal thread 42 is approximately that Outside diameter of the synthetic fiber rope 6 included Rope sheath 12 corresponds. For establishing the contact the open end of the pipe socket 41 is axially on the free End of the synthetic fiber rope 6 and mounted by turning the Short-circuit sleeve 40 around its longitudinal axis on the rope end screwed on. As a result of the rotary movement, this cuts Internal thread 42 in the cable sheath 12, the Short-circuit sleeve 40 with the outermost strand layer and the indicator fibers 9 running therein comes into contact and this short-circuits.

    Die Ausführung der Kontaktiereinrichtung 5 gemäss Figur 5 dient zur Bildung eines Kurzschlusses der Indikatorfasern 9 eines sogenannten Zwillingsseils 7. Das Zwillingsseil 7 besteht aus zwei Litzenseilen 6 mit entgegengesetzter Drehrichtung, die über einen gemeinsamen Seilmantel 8 verdrehfest in ihrer parallelen Lage zueinander fixiert und zum Zwillingsseil 7 verbunden sind. Jede Stirnfläche der beiden Litzenseile 6 ist mit einer Kurzschlussscheibe 44 und die Kurzschlussscheiben 44 durch ein Überbrückungsblech 45 elektrisch leitend miteinander verbunden, bzw. kurzgeschlossen. Das Überbrückungsblech 45 weist zwei Durchgangsbohrungen 46 auf, die im Abstand der Seillängsachsen der Litzenseile 6 ausgebildet sind. Die Kurzschlussscheiben 44 und das Überbrückungsblech 45 sind axial hintereinander mit Hilfe zweier durch die Bohrungen 46,47 durchgreifender Befestigungsschrauben 48 gegen die Stirnfläche des Zwillingsseils 7 gespannt. Die beispielsweise als Senkfurchschrauben ausgebildeten Befestigungsschrauben 48 schneiden sich in innenliegende Litzenlagen beider Litzenseile 6 des Zwillingsseils 7 ein und spannen so die Kontaktschneiden 49 der Kurzschlussscheiben 44 gegen die Litzen 10 der Decklage 50, welche die Indikatorfasern 9 enthalten. The design of the contacting device 5 according to FIG. 5 serves to form a short circuit of the indicator fibers 9 a so-called twin rope 7. The twin rope 7 consists of two stranded ropes 6 with opposite Direction of rotation via a common cable sheath 8 fixed against rotation in their parallel position to each other and are connected to the twin rope 7. Every face of the two stranded wires 6 is with a short-circuit disc 44 and the short-circuit disks 44 through a bridging plate 45 electrically connected to each other, or short-circuited. The bridging plate 45 has two Through holes 46 on the distance of Rope longitudinal axes of the stranded cables 6 are formed. The Short-circuit disks 44 and the bridging plate 45 are axially one after the other with the help of two through the holes 46,47 penetrating fastening screws 48 against the End face of the twin rope 7 stretched. The trained for example as countersunk screws Fastening screws 48 cut into the inside Strand layers of both strand cables 6 of the twin cable 7 and so clamp the contact cutting edges 49 of the Short-circuiting washers 44 against the strands 10 of the cover layer 50, which contain the indicator fibers 9.

    Bei einer Aufzuganlage werden zur Überwachung der Ablegereife des Zwillingsseils 7 die Kurzschlussscheiben 44 beispielsweise auf der Gegengewichtsseite eines als Tragseil dienenden Zwillingsseils 7 in beschriebener Weise elektrisch leitend miteinander verbunden. Am kabinenseitigen Ende des Zwillingsseiles 7 erfolgt dann die Speisung der Überwachungsspannung in eines der beiden Litzenseile 6. Am anderen Litzenseil 6 des gleichen Seilendes der mittels Kontaktierungseinrichtung 5 in Reihe geschaltenen Litzenseile 6 des Zwillingsseils 7 wird beispielsweise der Gesamtwiderstand der Indikatorfasern 9 bzw. der Indikatorfaserschaltung gemessen. Bei einer spezifischen Zunahme des elektrischen Widerstands kann in dieser Art darauf geschlossen werden, dass eine oder aber mehrere Indikatorlitzen 9 ausgefallen sind. Bei Überschreiten einer bestimmten Ausfallsrate wird dann angezeigt, dass das Zwillingsseil 7 ausgewechselt werden muss.In an elevator system to monitor the Discard of the twin rope 7, the short-circuit disks 44 for example on the counterweight side as a suspension cable serving twin rope 7 in the manner described electrically conductively connected. At the cabin end of the Twin ropes 7 are then fed Monitoring voltage in one of the two strands 6. Am another strand rope 6 of the same rope end by means of Contacting device 5 connected in series Stranded ropes 6 of the twin rope 7 is, for example, the Total resistance of the indicator fibers 9 or Indicator fiber circuit measured. With a specific Electrical resistance can increase in this way conclude that one or more Indicator strands 9 have failed. If one is exceeded certain failure rate is then displayed that the Twin rope 7 must be replaced.

    Dem Fachmann stehen bei Kenntnis der vorliegenden Erfindung vielfältige andere Möglichkeiten der Realisierung von Befestigungsmitteln frei. So ist auch ein Verkleben oder Verpressen eines Kurzschlusselements am Kunstfaserseilende möglich.Those skilled in the art are familiar with the present invention diverse other ways of realizing Fasteners free. So is gluing or Pressing a short-circuit element at the end of the synthetic fiber rope possible.

    Figur 6 zeigt eine Ausführung der Kontaktierungseinrichtung 51, die durch eine Klebstoffschicht 52 eines elektrisch leitenden Klebstoffs gebildet ist. Die Klebstoffschicht 52 besteht vorzugsweise aus einem Acrylharz oder einem Epoxydharz, welchen ein elektrisch leitender Füllstoff beigemengt ist. Hier verwendete Klebstoffe sind zum Beispiel die unter der handelsüblichen Bezeichnung ELECOLIT 342 und ELECOLIT 489 von der Firma PANACOL-ELOSOL GmbH erhältlichen silbergefüllten elektrisch leitenden Einkomponenten Beschichtungsmittel. ELECOLIT 342 ist ein silbergefülltes Acrylharz mit einem spezifischen Volumenwiderstand von 0,01 - 0,001 Ohm - cm. ELECOLIT 489 ist ein mit einer Silberlegierung gefülltes Epoxydharz und enthält einen entsprechend geringeren Silberanteil; sein spezifischer Volumenwiderstand ist 0,01 Ohm - cm. ELECOLIT 342 und ELECTOLIT 489 eignen sich deshalb besonders gut zur Herstellung von elektrisch leitenden Verbindungen.Figure 6 shows an embodiment of the contacting device 51 by an adhesive layer 52 of an electrical conductive adhesive is formed. The adhesive layer 52 consists preferably of an acrylic resin or a Epoxy resin, which is an electrically conductive filler is included. Adhesives used here are for example the under the commercial name ELECOLIT 342 and ELECOLIT 489 available from PANACOL-ELOSOL GmbH silver-filled electrically conductive one-component Coating agent. ELECOLIT 342 is a silver filled Acrylic resin with a volume resistivity of 0.01 - 0.001 ohm - cm. ELECOLIT 489 is one with one Silver alloy filled epoxy resin and contains one correspondingly lower silver content; be more specific Volume resistance is 0.01 ohm - cm. ELECOLIT 342 and ELECTOLIT 489 are therefore particularly suitable for Manufacture of electrically conductive connections.

    Die Endkontaktierung mittels eines elektrisch leitenden Klebstoffs ist einfach und schnell herzustellen. Der elektrisch leitende Klebstoff kann mit einem Pinsel auf die Stirnfläche am Seilende des Kunstfaserseils 6 oder des Zwillingsseils 7 aufgetragen werden und trocknet bei Raumtemperatur aus, wobei er die harte, zäheastische Kunststoffschicht 52 bildet. Im Unterschied zum herkömmichen Kurzschliessen mittels Klemmen oder mechanischen Kontaktierelementen bleibt die Güte der Seilschnittfläche in weitem Bereich ohne Einfluss auf die zuverlässige Kontaktierung der Indikatorfasern 9. Der flüssig aufgetragene elektrisch leitende Klebstoff dringt in die Zwischenräume zwischen den Litzen 10 ein und gleicht auf diese Weise Längenunterschiede der Indikatorlitzenenden an der Stirnfläche am des Seilende des Kunstfaserseils 6 aus. Gleichzeitig ist die Klebstoffschicht 52 nach dem Aushärten des Klebstoffs damit fest im Seilende des Kunstfaserseils 6 verankert.The end contact by means of an electrically conductive Adhesive is easy and quick to make. The electrically conductive glue can be applied to the brush with a brush End face at the rope end of the synthetic fiber rope 6 or Twin rope 7 are applied and dries Room temperature, being the hard, tough-looking Plastic layer 52 forms. In contrast to the conventional Short circuit by means of clamps or mechanical The quality of the rope cut surface remains in contacting elements wide area without affecting the reliable Contacting the indicator fibers 9. The liquid applied electrically conductive adhesive penetrates into the Gaps between the strands 10 and equalizes this way, differences in length of the indicator wire ends the end face of the end of the synthetic fiber rope 6. At the same time, the adhesive layer 52 is after curing of the adhesive firmly in the rope end of the synthetic fiber rope 6 anchored.

    Wie in Figur 6 dargestellt kann beispielsweise eine gummielastische Überstülpmuffe 53 über das Seilende des Kunstfaserseils 6 gestülpt werden, welches die Klebstoffschicht 52 vor mechanischem Verschleiss schützt. As shown in Figure 6, for example rubber elastic sleeve 53 over the rope end of the Synthetic fiber rope 6, which the Adhesive layer 52 protects against mechanical wear.
