Description

Gegenstand der Erfindung ist ein System zur elektrischen Kontaktierung von Zugträgern in Tragmitteln, um Tragmittel in Aufzugsanlagen zu überwachen.The invention relates to a system for electrical contacting of tension members in suspension means to monitor suspension means in elevator systems.

Bei manchen Fördereinrichtungen wie beispielsweise Aufzugsanlagen, Kranen oder Hebezügen, werden riemenförmige Tragmittel eingesetzt. Diese Tragmittel umfassen im Allgemeinen mehrere aus Strahldrähten bestehende Zugträger, welche die von dem Tragmittel aufzunehmenden Zugkräfte aufnehmen. Die Zugträger sind im Allgemeinen von einem Mantel aus Kunststoff umgeben. Der Mantel schützt die Zugträger beispielsweise vor mechanischem Verschleiss, weil die Tragmittel häufig über Umlenkstellen geführt werden. Zudem verbessert der Mantel die Traktion des Tragmittels auf Umlenk- oder Antriebsrollen, und fixiert die Anordnung der Zugträger untereinander.In some conveyors such as elevator systems, cranes or hoists, belt-shaped suspension means are used. These support means generally comprise a plurality of beam wires consisting of tensile carriers which absorb the tensile forces to be absorbed by the suspension element. The tension members are generally surrounded by a plastic sheath. The jacket protects the tension members, for example against mechanical wear, because the support means are often guided over deflection points. In addition, the jacket improves the traction of the suspension element on deflection or drive rollers, and fixed the arrangement of the tension members with each other.

Solche Tragmittel sind innerhalb einer Fördereinrichtung ein sicherheitskritisches Bauteil. Ihr Versagen, bzw. Bruch kann zu einem Herabfallen des zu fördernden Gutes führen. Dies kann zu erheblichen Sach- bzw. Personenschäden führen. Aus diesem Grund werden Prüfeinheiten in Fördereinrichtungen eingesetzt, welche insbesondere den mechanischen Zustand der Zugträger überprüfen. Schäden an den die Kräfte aufnehmenden Zugträgern sollen dadurch frühzeitig erkannt werden können, so dass das Tragmittel bei einer Beschädigung ausgewechselt werden kann, um ein Versagen der Fördereinrichtung zu verhindern.Such suspension means are within a conveyor a safety-critical component. Their failure, or breakage can lead to a fall of the good to be promoted. This can lead to considerable property damage or personal injury. For this reason, test units are used in conveyors, which in particular check the mechanical condition of the tension members. Damage to the forces absorbing tension members should be able to be detected early, so that the support means can be replaced in case of damage to prevent failure of the conveyor.

Die Zugträger sind von dem elektrisch isolierenden Mantel aus Kunststoff umgeben. Zur Durchführung einer Prüfung des Zustandes der Zugträger ist bei einigen Verfahren eine Kontaktierung eines Kontaktelementes mit dem Zugträger erforderlich. Bei einem bekannten Verfahren wird mit Hilfe des Kontaktelementes durch die Zugträger ein elektrischer Strom geleitet, der als Prüfstrom dazu dient, den Zustand der Zugträger festzustellen. Daneben kommen auch andere Prüfverfahren, die nicht mit elektrischem Strom arbeiten, z.B. Ultraschall, in Betracht.The tension members are surrounded by the electrically insulating jacket made of plastic. In order to carry out a test of the state of the tension members, contacting of a contact element with the tension member is required in some methods. In a known method, an electrical current is passed with the aid of the contact element through the tension members, which serves as a test current to determine the state of the tension members. In addition, other test methods that do not use electric current, e.g. Ultrasound, into consideration.

Die DE 3 934 654 A1 zeigt ein gattungsbildendes Tragmittel. Die Enden der Zugträger sind dabei paarweise leitend mit einem Brückenteil verbunden, so dass die Zugträger des Tragmittels elektrisch in Reihe geschaltet sind. Die Zugträger des Tragmittels sind über ein Amperemeter an eine Spannungsquelle angeschlossen, so dass mittels des Prüfstromes, der durch sämtliche Zugträger aufgrund der elektrischen Schaltung in Reihe geleitet wird, der Zustand der Zugträger beurteilt werden kann.The DE 3 934 654 A1 shows a generic support means. The ends of the tension members are connected in pairs conductive with a bridge part, so that the tension members of the support means are electrically connected in series. The tension members of the suspension element are over an ammeter connected to a voltage source, so that by means of the test current, which is passed through all train carrier due to the electrical circuit in series, the state of the tension members can be assessed.

Die WO 2005/094249 A2 zeigt ein System zur Kontaktierung eines Tragmittels, bei dem die Kontaktelemente senkrecht zu einer Längsachse der Zugträger den Mantel des Tragmittels durchstossen und dann in die Zugträger eindringen. Nachteiligerweise können dabei die Kontaktelemente aufgrund des erforderlichen Durchstossvorganges durch den Mantel die Zugträger verfehlen.The WO 2005/094249 A2 shows a system for contacting a support means, wherein the contact elements perpendicular to a longitudinal axis of the tension members pierce the jacket of the suspension element and then penetrate into the tension members. Disadvantageously, the contact elements can miss the tension members due to the required piercing process through the jacket.

Eine Aufgabe der vorliegenden Erfindung besteht darin, ein System zur elektrischen Kontaktierung von Zugträgern in Tragmitteln zur Verfügung zu stellen, bei welchem die Zugträger des Tragmittels zuverlässig und in genauer Weise von einem Kontaktelement kontaktiert werden können, um einen Zustand der Zugträger ermitteln zu können. Das System soll in der Handhabung einfach und zuverlässig sein sowie geringe Herstellungskosten aufweisen.An object of the present invention is to provide a system for electrical contacting of tension members in support means available, in which the tension members of the support means can be reliably and accurately contacted by a contact element to determine a state of the tension members can. The system should be easy to use and reliable and have low production costs.

Zur Lösung dieser Aufgabe wird ein System zur elektrischen Kontaktierung von Zugträgern in Tragmitteln vorgeschlagen, welches ein Tragmittel und eine Kontaktierungsvorrichtung umfasst. Das Tragmittel hat einen Mantel und mindestens vier Zugträger, welche parallel zueinander im Mantel angeordnet sind, und welche im Wesentlichen auf einer Ebene liegen. Die Kontaktierungsvorrichtung hat ein Kontaktelement. Das Kontaktelement hat eine Schneidseite zur Durchdringung des Mantels, wobei die Schneidseite des Kontaktelements derart durch den Mantel geführt ist, dass das Kontaktelement die mindestens vier Zugträger zumindest mit der Schneidseite kontaktiert.To solve this problem, a system for electrical contacting of tension members in suspension means is proposed, which comprises a support means and a contacting device. The suspension element has a jacket and at least four tension members, which are arranged parallel to one another in the jacket, and which lie essentially on one plane. The contacting device has a contact element. The contact element has a cutting side for penetrating the jacket, wherein the cutting side of the contact element is guided through the jacket such that the contact element contacts the at least four tension members at least with the cutting side.

Diese Lösung hat den Vorteil, dass alle Zugträger eines Tragmittels mit nur einem Kontaktelement kontaktiert werden können. Somit muss nur ein Kontaktelement durch den Mantel des Tragmittels geführt werden. Dies vereinfacht die Anwendung dieses Systems zur elektrischen Kontaktierung von Zugträgern in Tragmitteln wesentlich. Zudem können durch ein solches System alle Zugträger im Tragmittel auf einfache Art und Weise parallel geschaltet werden.This solution has the advantage that all tension members of a suspension element can be contacted with only one contact element. Thus, only one contact element has to be guided through the jacket of the suspension element. This significantly simplifies the application of this system for the electrical contacting of tension members in suspension elements. In addition, by means of such a system, all tension members in the suspension element can be connected in parallel in a simple manner.

Das Kontaktelement mit der Schneidseite hat zudem den Vorteil, dass das Kontaktelement messerartig durch den Mantel getrieben werden kann, um die Zugträger zu kontaktieren.The contact element with the cutting side also has the advantage that the contact element can be driven like a knife through the jacket to contact the tension members.

Eine solche Schneidseite kann beispielsweise als geradlinige Kante ausgebildet sein, oder aber als gezackte Kante mit Kontaktspitzen oder als Kante mit Kontaktvertiefungen oder Kontakterhöhungen. Solche Kontaktspitzen oder Kontaktvertiefungen bzw. Kontakterhöhungen haben den Vorteil, dass die Zugträger jeweils von einer Kontaktspitze bzw. Kontaktvertiefung oder Kontakterhöhung zuverlässig kontaktiert werden können. Vorteilhafterweise ist jeweils eine Kontaktspitze bzw. Kontaktvertiefung bzw. Kontakterhöhung pro Zugträger vorgesehen. Dadurch können alle Zugträger eines Tragmittels mit einem einzigen Kontaktelement zuverlässig kontaktiert werden.Such a cutting side may be formed, for example, as a straight edge, or as a serrated edge with contact tips or as an edge with contact recesses or contact increases. Such contact tips or contact recesses or contact increases have the advantage that the tension members can each be reliably contacted by a contact tip or contact recess or contact increase. Advantageously, a contact tip or contact depression or contact increase per tensile carrier is provided in each case. As a result, all tensile carriers of a suspension element can be reliably contacted with a single contact element.

In einer weiteren vorteilhaften Ausführungsform umfasst die Kontaktierungsvorrichtung ein erstes und ein zweites Halteelement. Das Tragmittel ist dabei im Wesentlichen zwischen dem ersten und dem zweiten Halteelement angeordnet. Das Kontaktelement ist von einem der beiden Halteelemente gestützt, so dass die Schneidseite des Kontaktelementes gegen das Tragmittel gerichtet ist. Solche Halteelemente vereinfachen es, das Kontaktelement in gewünschter Weise durch den Mantel des Tragmittels zu führen.In a further advantageous embodiment, the contacting device comprises a first and a second holding element. The suspension element is arranged substantially between the first and the second holding element. The contact element is supported by one of the two holding elements, so that the cutting side of the contact element is directed against the support means. Such holding elements make it easier to guide the contact element in the desired manner by the jacket of the support means.

In einer weiteren vorteilhaften Ausführungsform sind das erste und zweite Halteelement durch ein erstes und ein zweites Befestigungselement miteinander verbunden. Vorteilhafterweise sind durch eine Betätigung des ersten und des zweiten Befestigungselementes das erste und zweite Halteelement zueinander verschiebbar. Dadurch können die Halteelemente zueinander geführt werden, um dadurch das Kontaktelement in den Mantel des Tragmittels zu treiben.In a further advantageous embodiment, the first and second retaining element are connected to each other by a first and a second fastening element. Advantageously, the actuation of the first and the second fastening element, the first and second retaining element to each other. As a result, the retaining elements can be guided relative to one another in order thereby to drive the contact element into the jacket of the suspension element.

In einer weiteren vorteilhaften Ausführungsform sind ein Scharnier und ein Befestigungselement vorgesehen, um das erste und das zweite Halteelement miteinander zu verbinden. Dies hat den Vorteil, dass nur ein Befestigungselement betätigt werden muss, um das erste und zweite Halteelement zueinander zu verschieben und dadurch das Kontaktelement in den Mantel des Tragmittels zu treiben.In a further advantageous embodiment, a hinge and a fastening element are provided in order to connect the first and the second retaining element to one another. This has the advantage that only one fastening element has to be actuated in order to displace the first and second retaining elements relative to one another and thereby to drive the contact element into the jacket of the suspension element.

In einer beispielhaften Ausführungsform sind das erste und das zweite Befestigungselement bzw. das eine Befestigungselement jeweils als Schraube mit Mutter ausgebildet. Es sind jedoch auch andere Ausführungsformen möglich.In an exemplary embodiment, the first and the second fastening element and the one fastening element are each designed as a screw with nut. However, other embodiments are possible.

In einer vorteilhaften Ausführungsform wird an einem ersten Kontaktelement, welches an einem ersten Tragmittelende angeordnet ist, in einem Verwendungszustand eine elektrische Spannung angelegt, wobei ein elektrischer Strom gemessen wird, welcher vom ersten Kontaktelement zu einem zweiten Kontaktelement, welches an einem zweiten Tragmittelende angeordnet ist, fliesst. Dadurch können allfällige Schäden in den Zugträgern festgestellt werden.In an advantageous embodiment, at a first contact element, which at a first end of the support means is arranged, applied in a use state, an electrical voltage, wherein an electric current is measured, which flows from the first contact element to a second contact element, which is arranged at a second Tragmittelende flows. As a result, any damage can be detected in the train carriers.

In einer weiteren vorteilhaften Ausführungsform weist das Tragmittel zumindest fünf Zugträger auf, wobei das Kontaktelement die zumindest fünf Zugträger kontaktiert.In a further advantageous embodiment, the suspension element has at least five tension members, wherein the contact element contacts the at least five tension members.

In einem weiteren vorteilhaften Ausführungsbeispiel wird eine Aufzugsanlage mit einem solchen System zur elektrischen Kontaktierung von Zugträgern in Tragmitteln zur Verfügung gestellt. Dabei sind die Kontaktierungsvorrichtungen vorzugsweise an nicht überrollten Bereichen des Tragmittels angeordnet.In a further advantageous embodiment, an elevator installation is provided with such a system for the electrical contacting of tension members in suspension elements. The contacting devices are preferably arranged on non-overrolled areas of the support means.

In Figur 1 sind zwei Kontaktierungsvorrichtungen 2 zur Kontaktierung eines Tragmittels 1 in einer Aufzugsanlage 40 eingebaut. Die schematische und beispielhafte Aufzugsanlage 40 beinhaltet zumindest eine Aufzugskabine 41, ein Gegengewicht 42 und ein Tragmittel 1 sowie eine Treibscheibe 43 mit zugeordnetem Antriebsmotor 44. Die Treibscheibe 43 treibt das Tragmittel 1 an und bewegt damit die Aufzugskabine 41 und das Gegengewicht 42 gegengleich. Der Antriebsmotor 44 ist von einer Aufzugssteuerung 45 gesteuert. Die Kabine 41 ist gestaltet, um Personen und/oder Güter aufzunehmen und zwischen Etagen eines Gebäudes zu transportieren. Kabine 41 und Gegengewicht 42 sind entlang von Führungen geführt (nicht dargestellt). Im Beispiel sind die Kabine 41 und das Gegengewicht 42 jeweils an Tragrollen 46 aufgehängt. Das Tragmittel 1 ist dabei an einer ersten Tragmittelbefestigungsvorrichtung 47 festgemacht, und dann zunächst um die Tragrolle 46 des Gegengewichts 42 geführt. Sodann ist das Tragmittel 1 über die Treibscheibe 43 gelegt, um die Tragrolle 46 der Kabine 41 geführt und schliesslich durch eine zweite Tragmittelbefestigungsvorrichtung 47 mit einem Fixpunkt verbunden. Dies bedeutet, dass das Tragmittel 1 mit einer entsprechend einem Umhängefaktor höheren Geschwindigkeit über den Antrieb 43, 44 läuft. Im Beispiel beträgt der Umhängefaktor 2:1.In FIG. 1 two contacting devices 2 for contacting a support means 1 in an elevator installation 40 are installed. The schematic and exemplary elevator installation 40 includes at least one elevator car 41, a counterweight 42 and a suspension element 1 and a traction sheave 43 with associated drive motor 44. The traction sheave 43 drives the support means 1 and thus moves the elevator car 41 and the counterweight 42 gegengleich. The drive motor 44 is controlled by an elevator control 45. The cabin 41 is designed to receive people and / or goods and to transport between floors of a building. Cabin 41 and counterweight 42 are guided along guides (not shown). In the example, the cabin 41 and the counterweight 42 are each suspended on support rollers 46. The support means 1 is fastened to a first support means fastening device 47, and then first guided around the support roller 46 of the counterweight 42. Then the support means 1 is placed over the traction sheave 43, guided around the support roller 46 of the car 41 and finally connected by a second suspension means fastening device 47 with a fixed point. This means that the suspension element 1 runs with a higher speed via the drive 43, 44 in accordance with a transfer factor. In the example, the wrap factor is 2: 1.

Ein loses Ende 1.1 des Tragmittels 1 ist mit der Kontaktierungsvorrichtung 2 zur temporären oder permanenten Kontaktierung des Tragmittels 1 versehen. Im dargestellten Beispiel ist an beiden Enden des Tragmittels 1 eine derartige Kontaktierungsvorrichtung 2 angeordnet. In einer alternativen nicht dargestellten Ausführungsform ist nur eine Kontaktierungsvorrichtung 2 an einem der Tragmittelenden 1.1 angeordnet. Die Tragmittelenden 1.1 sind von der Zugkraft im Tragmittel 1 nicht mehr belastet, da diese Zugkraft bereits vorgängig über die Tragmittelbefestigungen 47 in das Gebäude geleitet ist. Die Kontaktierungsvorrichtungen 2 sind also in einem nicht überrollten Bereich des Tragmittels 1 angeordnet.A loose end 1.1 of the suspension element 1 is provided with the contacting device 2 for the temporary or permanent contacting of the suspension element 1. In the example shown, such a contacting device 2 is arranged at both ends of the support means 1. In an alternative embodiment, not shown, only one contacting device 2 is arranged on one of the support means ends 1.1. The Tragmittelenden 1.1 are no longer burdened by the tensile force in the suspension element 1, since this tensile force is already passed through the support means fasteners 47 into the building. The contacting devices 2 are therefore arranged in a non-overrun area of the suspension element 1.

Die gezeigte Aufzugsanlage 40 in Figur 1 ist beispielhaft. Andere Umhängefaktoren und Anordnungen sind möglich. Die Kontaktierungsvorrichtung 2 zur Kontaktierung des Tragmittels 1 wird dann entsprechend der Platzierung der Tragmittelbefestigungen 47 angeordnet.The elevator installation 40 shown in FIG FIG. 1 is exemplary. Other cap factors and arrangements are possible. The contacting device 2 for contacting the support means 1 is then arranged according to the placement of the support means fastenings 47.

In den Figuren 2a bis 2d sind verschiedene Ausführungsbeispiele von Tragmitteln 1 dargestellt, welche in einem System zur elektrischen Kontaktierung von Zugträgen in Tragmitteln verwendet werden können. Die Tragmittel 1 weisen jeweils einen Mantel 5 und zumindest vier Zugträger 3 auf. Die Zugträger 3 sind dabei parallel zueinander im Mantel 5 angeordnet, und liegen im Wesentlichen auf einer Ebene. Die Anzahl der Zugträger 3 und die Form des Mantels 5 können dabei unterschiedlich ausgestaltet sein.In the FIGS. 2a to 2d different embodiments of support means 1 are shown, which can be used in a system for electrical contacting of tensile forces in suspension means. The support means 1 each have a jacket 5 and at least four tension members 3. The tension members 3 are arranged parallel to each other in the jacket 5, and lie substantially on one level. The number of tension members 3 and the shape of the shell 5 can be designed differently.

Figur 2a zeigt ein beispielhaftes Tragmittel 1 mit einem rechteckigen Querschnitt und sechs parallel zueinander angeordneten Zugträgern 3. Das Tragmittel 1 weist eine Rückseite 6 und eine Traktionsseite 4 auf. In diesem Ausführungsbeispiel ist das Tragmittel 1 symmetrisch ausgestaltet, d.h. die Rückseite 6 kann als Traktionsseite eingesetzt werden, bzw. die Traktionsseite 4 kann als Rückseite eingesetzt werden. FIG. 2a shows an exemplary support means 1 with a rectangular cross-section and six mutually parallel tension members 3. The support means 1 has a back 6 and a traction side 4. In this embodiment, the support means 1 is designed symmetrically, ie the back 6 can be used as a traction side, or the traction side 4 can be used as a back.

In Figur 2b ist ein weiteres beispielhaftes Tragmittel 1 dargestellt. In diesem Ausführungsbeispiel weist die Traktionsseite 4 Längsrippen 7 auf. Solche Längsrippen 7 verbessern das Traktionsverhalten des Tragmittels 1 und erlauben eine präzise seitliche Führung des Tragmittels 1 auf Antriebs- bzw. Umlenkrollen. Die Rückseite 6 ist wie in Figur 2a ohne zusätzliche Strukturen ausgebildet. In diesem Ausführungsbeispiel umfasst das Tragmittel 1 sechs Längsrippen 7, wobei jeder Längsrippe 7 zwei Zugträger 3 zugeordnet sind. Somit sind insgesamt zwölf Zugträger 3 im Mantel 5 des Tragmittels 1 angeordnet.In FIG. 2b is another exemplary suspension means 1 shown. In this embodiment, the traction side 4 has longitudinal ribs 7. Such longitudinal ribs 7 improve the traction of the support means 1 and allow a precise lateral guidance of the support means 1 on drive or deflection rollers. The back 6 is as in FIG. 2a formed without additional structures. In this embodiment, the support means 1 comprises six longitudinal ribs 7, wherein each longitudinal rib 7 are assigned two tension members 3. Thus, a total of twelve tension members 3 are arranged in the jacket 5 of the suspension element 1.

In Figur 2c ist eine weitere beispielhafte Ausführungsform eines Tragmittels 1 dargestellt. In diesem Ausführungsbeispiel umfasst das Tragmittel 1 vier Zugträger 3 im Mantel 5. Dabei ist der Mantel 5 um die Zugträger 3 konturiert, so dass die Traktionsseite 4 und auch die Rückseite 6 eine wellenartige Form aufweisen.In Figure 2c is a further exemplary embodiment of a support means 1 is shown. In this embodiment, the suspension element 1 comprises four tension members 3 in the jacket 5. The jacket 5 is contoured around the tension members 3, so that the traction side 4 and also the rear side 6 have a wave-like shape.

In Figur 2d ist eine weitere beispielhafte Ausführungsform eines Tragmittels 1 dargestellt. Dieses beispielhafte Tragmittel 1 umfasst 8 zueinander parallel angeordnete Zugträger 3, welche vom Mantel 5 umgeben sind. Die Rückseite 6 weist eine Führungsrippe 8 auf. Dadurch wird erreicht, dass das Tragmittel 1, auch wenn es auf seiner Rückseite 6 über Umlenkrollen geführt ist, seitlich führbar ist. Zudem weist das Tragmittel 1 auf seiner Traktionsseite 4 zwei Führungsnuten 9 auf. Mit entsprechenden Führungsrillen auf einer Treib- bzw. Umlenkrolle lässt sich so das Tragmittel 1 seitlich führen.In Figure 2d is a further exemplary embodiment of a support means 1 is shown. This exemplary support means 1 comprises 8 mutually parallel tension members 3, which are surrounded by the jacket 5. The back 6 has a guide rib 8. This ensures that the support means 1, even if it is guided on its rear side 6 via deflection rollers, is laterally feasible. In addition, the support means 1 on its traction side 4 on two guide grooves 9. With appropriate guide grooves on a drive or deflection pulley, the suspension element 1 can thus be guided laterally.

Die in den Figuren 2a bis 2d dargestellten Tragmittel 1 sind beispielhafte Ausführungsformen eines Tragmittels 1, welches in einem System zur elektrischen Kontaktierung von Zugträgern in Tragmitteln verwendet werden kann. Es versteht sich von selbst, dass beliebige andere Ausführungsformen von Tragmitteln in einem solchen System verwendet werden können.The in the FIGS. 2a to 2d shown suspension means 1 are exemplary embodiments of a support means 1, which can be used in a system for electrical contacting of tension members in suspension means. It goes without saying that any other embodiments of suspension means can be used in such a system.

In den Figuren 3a bis 3d sind verschiedene Ausführungsbeispiele eines Kontaktelementes 10 zur Verwendung in einem System zur elektrischen Kontaktierung von Zugträgern in Tragmitteln dargestellt. Diese Kontaktelemente 10 weisen jeweils einen Kontaktelementkörper 12 und eine Schneidseite 11 auf. Die Schneidseite 11 ist dazu geeignet, den Mantel eines Tragmittels zu durchdringen und dadurch das Kontaktelement 10 an die Zugträger im Innern des Tragmittels heranzuführen. Der Kontaktelementkörper 12 ist vorzugsweise aus einem elektrisch leitenden Material hergestellt, wie beispielsweise einem Metall. Der Kontaktelementkörper 12 ist zudem vorzugsweise genügend robust ausgebildet, so dass das Kontaktelement 10 beim Einführen in den Tragmittelmantel nicht Schaden nimmt. Die Schneidseite 11 ist vorzugsweise ähnlich einem Grat einer Messerschneide aufgebaut, um eine entsprechende Schneidewirkung zu ermöglichen.In the FIGS. 3a to 3d are different embodiments of a contact element 10 for use in a system for electrical contacting of tension members shown in support means. These contact elements 10 each have a contact element body 12 and a cutting side 11. The cutting side 11 is adapted to penetrate the shell of a support means and thereby bring the contact element 10 to the tension members in the interior of the suspension element. The contact element body 12 is preferably made of an electrically conductive material, such as a metal. The contact element body 12 is also preferably sufficiently robust, so that the contact element 10 does not damage during insertion into the suspension element casing. The cutting side 11 is preferably constructed similar to a ridge of a knife edge to allow a corresponding cutting action.

Die Schneidseite 11 des Kontaktelementes 10 in Figur 3b ist im Wesentlichen geradlinig ausgebildet. Ein solches Kontaktelement 10 kann für viele verschiedene Tragmittel eingesetzt werden, da die Schneidseite 11 nicht auf eine bestimmte Anzahl und Anordnung der Zugträger im Tragmittel zugeschnitten ist. Demgegenüber weisen die Schneidseiten 11 in den Figuren 3a, 3c und 3d eine unregelmässige Form auf. Solche unregelmässigen Formen sind auf das mit dem Kontaktelement 10 zu verwendende Tragmittel abgestimmt. So ist beispielsweise das Kontaktelement 10 aus Figur 3a für ein Tragmittel mit sechs Zugträgern vorgesehen. Die Kontaktspitzen 13 ermöglichen dabei ein zuverlässiges Kontaktieren der einzelnen Zugträger. Zudem erleichtern die Kontaktspitzen 13 ein Durchführen des Kontaktelementes 10 durch den Mantel des Tragmittels. Die Kontaktvertiefungen 14, bzw. Kontakterhöhungen 15 in den Figuren 3c und 3d dienen einem ähnlichen Zweck wie die Kontaktspitzen 13 in Figur 3a. Die Kontaktvertiefungen 14 sind in einem Verwendungszustand jeweils um einen Zugträger angeordnet. Dadurch werden die Zugträger nicht punktuell kontaktiert, wie dies mit Kontaktspitzen der Fall ist, sondern die Zugträger werden auf einem grösseren Teil ihrer Umfangsoberfläche von den Kontaktvertiefungen 14 des Kontaktelements 10 kontaktiert. Die Kontakterhöhungen 15 haben eine ähnliche Wirkung wie die Kontaktspitzen 13, mit dem Unterschied, dass die Kontakterhöhungen 15 abgerundet sind.The cutting side 11 of the contact element 10 in FIG. 3b is essentially rectilinear. Such a contact element 10 can be used for many different support means, since the cutting side 11 is not tailored to a certain number and arrangement of the tension members in the support means. In contrast, the cutting sides 11 in the FIGS. 3a, 3c and 3d an irregular shape. Such irregular shapes are matched to the support element to be used with the contact element 10. For example, the contact element 10 is made FIG. 3a intended for a suspension with six tension members. The contact tips 13 enable reliable contacting of the individual tension members. In addition, the contact tips 13 facilitate a passage of the contact element 10 through the jacket of the suspension element. The contact recesses 14, or contact increases 15 in the Figures 3c and 3d serve a similar purpose as the contact tips 13 in FIG FIG. 3a , The contact recesses 14 are arranged in a use state in each case by a tension member. As a result, the tension members are not contacted punctually, as is the case with contact tips, but the tension members are contacted on a larger part of their peripheral surface by the contact recesses 14 of the contact element 10. The contact increases 15 have a similar effect as the contact tips 13, with the difference that the contact increases 15 are rounded.

Die Kontaktelemente 10 in den Figuren 3a bis 3d sind wiederum beispielhafte Ausführungsformen zur Verwendung in einem System zur elektrischen Kontaktierung von Zugträgern in Tragmitteln. Es versteht sich von selbst, dass ein solches Kontaktelement 10 auf verschiedene andere, nicht dargestellte Arten, ausgebildet werden kann.The contact elements 10 in the FIGS. 3a to 3d Again, exemplary embodiments are for use in a system for electrical contacting of tension members in suspension elements. It goes without saying that such a contact element 10 can be formed in various other ways, not shown.

In den Figuren 4a und 4b ist jeweils ein System zur elektrischen Kontaktierung von Zugträgern in Tragmitteln dargestellt. Dabei ist in Figur 4a ein Tragmittel 1 mit einem rechteckigen Querschnitt und sechs parallel zueinander angeordneten Zugträgern 3 dargestellt. In Figur 4b ist ein Tragmittel 1 mit einer wellenförmigen Traktions- bzw. Rückseite und vier parallel zueinander angeordneten Zugträgern 3 dargestellt. Die im jeweiligen System verwendeten Kontaktelemente 10 sind auf das jeweilige Tragmittel 1 abgestimmt. So ist in Figur 4a ein Kontaktelement 10 mit Kontaktspitzen 13 angeordnet, wobei die Anzahl der Kontaktspitzen 13 mit der Anzahl der Zugträger 3 übereinstimmt. In Figur 4b ist entsprechend ein Kontaktelement 10 mit Kontaktvertiefungen 14 dargestellt. Wiederum ist die Anzahl der Kontaktvertiefungen 14 mit der Anzahl der Zugträger 3 übereinstimmend.In the FIGS. 4a and 4b In each case, a system for electrical contacting of tension members is shown in support means. It is in FIG. 4a a support means 1 with a rectangular cross section and six mutually parallel tension members 3 shown. In FIG. 4b is a support means 1 with a wave-shaped traction or back and four mutually parallel tension members 3 shown. The contact elements 10 used in the respective system are matched to the respective support means 1. So is in FIG. 4a a contact element 10 is arranged with contact tips 13, wherein the number of contact tips 13 coincides with the number of tension members 3. In FIG. 4b Accordingly, a contact element 10 with contact recesses 14 is shown. Again, the number of contact recesses 14 with the number of tension members 3 is consistent.

Das Tragmittel 1 ist jeweils von einem ersten und einem zweiten Halteelement 16, 17 umgeben. Dabei ist das Kontaktelement 10 jeweils vom zweiten Halteelement 17 gestützt, so dass die Schneidseite 11 des Kontaktelementes 10 gegen das Tragmittel 1 gerichtet ist. Das erste und das zweite Halteelement 16, 17 sind durch ein erstes Befestigungselement 18 und ein zweites Befestigungselement 19 miteinander verbunden. Durch eine Betätigung der Befestigungselemente 18, 19 sind das erste und das zweite Halteelement 16, 17 zueinander verschiebbar. Durch eine solche Betätigung der Befestigungselemente 18, 19 wird also das Kontaktelement 10 in den Mantel 5 des Tragmittels 1 geführt. Die Befestigungselemente 18, 19 werden nun solange betätigt, bis das Kontaktelement 10 alle Zugträger 3 des Tragmittels 1 kontaktiert. In diesem Ausführungsbeispiel sind die Befestigungselemente 18, 19 jeweils als Schraube mit Mutter ausgebildet. Nach erfolgter Kontaktierung der Zugträger 3 durch das Kontaktelement 10 wird eine Spannung angelegt, so dass ein Prüfstrom durch die Zugträger 3 fliesst, um den Zustand der Zugträger 3 zu ermitteln.The support means 1 is in each case surrounded by a first and a second holding element 16, 17. In this case, the contact element 10 is supported in each case by the second holding element 17, so that the cutting side 11 of the contact element 10 is directed against the support means 1. The first and the second retaining element 16, 17 are connected to one another by a first fastening element 18 and a second fastening element 19. By an actuation of the fastening elements 18, 19, the first and the second holding element 16, 17 are mutually displaceable. By such an actuation of the fastening elements 18, 19 so the contact element 10 is guided in the jacket 5 of the support means 1. The fastening elements 18, 19 are now operated until the contact element 10 contacts all tension members 3 of the suspension element 1. In this embodiment, the fastening elements 18, 19 are each formed as a screw with nut. After contacting the tension members 3 by the contact element 10, a voltage is applied, so that a test current flows through the tension members 3 in order to determine the state of the tension members 3.

In einer alternativen nicht dargestellten Ausführungsform ist nur ein Befestigungselement 18, 19 vorgesehen, und das zweite Befestigungselement ist durch ein Scharnier ersetzt. Dadurch sind die beiden Halteelement 16, 17 bereits miteinander verbunden, was eine Montage vereinfacht, und es muss nur ein Befestigungselement 18, 19 betätigt werden, um die Kontaktierungsvorrichtung 2 am Tragmittel 1 anzuordnen.In an alternative embodiment, not shown, only one fastener 18, 19 is provided, and the second fastener is replaced by a hinge. As a result, the two retaining elements 16, 17 are already connected to one another, which simplifies assembly, and only one fastening element 18, 19 has to be actuated in order to arrange the contacting device 2 on the suspension element 1.
