Definitions
- the present invention relates to an elevator installation with a monitoring device for a suspension element, and to a method for monitoring at least one suspension element in an elevator installation.
- a test current can be applied to the tension members.
- a current flow, a voltage, an electrical resistance or an electrical conductivity is measured.
- a size measured in this way it is possible to deduce an integrity or a degree of wear of the suspension element. Namely, reduces the diameter of a tension member by fractures of individual wires or by metallic abrasion, the electrical resistance of this tension member increases.
- the patent US7123030B2 discloses such a method for determining a degree of wear of a belt-type suspension element. Based on a specific electrical resistance of electrically conductive tension members is closed on a breaking force of the suspension element.
- Such a method has the advantage that a situation-appropriate reaction to the different states of the suspension element is made possible.
- a weighting state By dividing it into three different damaged states of the tension members on the basis of a change in the electrical characteristics of the tension members, it is possible to assign a weighting state to a suspension element or all suspension elements of an elevator installation by appropriate weighting of these states.
- Such a warning state can in turn be used in a simple manner to trigger a corresponding reaction in accordance with the situation.
- this method allows to assess the condition of a suspension more accurate and thus avoid unnecessary shutdown of the elevator system or to prevent dangerous further operation of the elevator system.
- three states can be detected by the monitoring device during monitoring. This has the advantage that a condition of the suspension element can be estimated even more accurately than is possible with only two different defective states of the tension members.
- interrupted tension member means a situation in which a tension member is substantially interrupted at one location such that substantially no electrical current can flow over that location.
- Grounded tension member in this context means that a tension member is in contact with a grounded member such that electrical current applied to the tension member substantially drains off this grounded member.
- damaged tension member in this context means that the tension member has at least one point of damage, for example in the form of individual wire breaks or in the form of rusted wires, so that an electrical resistance of this tension member changes due to these damaged areas. Such damage to the tension members usually have the effect of increasing the electrical resistance of an affected tension member.
- a "damaged tension member” may also be present if, due to damage, two adjacent tension members are in electrical contact with each other. This is the case, for example, when the jacket material between two tension members is damaged or when a broken wire of a tension member contacts an adjacent tension member. Such cross-connections between tension members usually have the effect of reducing the electrical resistance of an affected tension member.
- These three different defective states of a tension member can be determined in a simple manner by determining an electrical resistance of the tension member. If the electrical resistance of a tension member tends to infinity, there is an interrupted tension member. If the electrical resistance of the tension member tends towards zero, then there is a grounded tension member. If the electrical resistance of a tension member changes, then there is a damaged tension member with at least one damaged point.
- Such a method has the advantage that both dangerous situations due to individual defective suspension means are recognized, as well as dangerous situations due to a sum of defects in various suspension elements of an elevator installation. For example, small defects in each one of three Carrying means of a lift system represent a dangerous condition, although the individual suspension means considered alone would not have to be assigned to a dangerous condition.
- a dangerous situation can be detected, in which only one of several support means of a lift system has defects, but so serious defects that a dangerous situation for the entire elevator system is present. If, in such a situation, one would only consider the totality of the defects of all the means of suspension, this situation would not be able to be correctly assessed.
- the warning state upon continuing to drive or continue operating the elevator system, the warning state will not cause the elevator system to continue driving, the warning state of first degree error to continue driving with a warning being canceled, and the warning state of the second degree error to shut down the elevator ,
- an interrupted tensile member or a grounded tensile member results in a more severe weighing condition than a damaged tensile member.
- the advantage of such an exemplary weighting of the various defects of the tension members is that, depending on the nature of the
- a suspension element with an interrupted tension member or a grounded tension member is assigned a second-order error in each case.
- a support means with at least one damaged tensile carrier then leads to a fault of the first degree if at most one tension member per suspension element has a damaged tension member and if the number of damaged tension members is smaller than the number of suspension elements.
- a support means with at least one damaged tensile carrier then leads to a second-degree error if more than one tensile member per suspension element is damaged or if the number of damaged tensile members is equal to or greater than the number of suspension elements.
- Such an exemplary weighting of the various defective states of the tensile carriers has the advantage that an elevator installation can continue to be operated in the case of non-hazardous defects with the deduction of an advance warning, but can be put out of operation in the event of dangerous defects of the tensile carriers.
- a predefined position of an elevator car is approached before the elevator installation is put out of operation for further journeys.
- a predefined position of the elevator car can be, for example, the next public stop starting from a current position of the elevator car.
- a maintenance center in charge of the elevator installation is informed of the detected condition of the tension members or of the condition associated therewith. This has the advantage that the maintenance center responsible for the elevator installation can plan a service or maintenance of the elevator installation according to this information.
- an elevator installation with at least one suspension element, wherein the suspension element comprises electrically conductive tension members, which are surrounded by an electrically insulating jacket.
- the elevator installation further comprises a monitoring device associated with the suspension element, wherein a method as described above can be carried out in the elevator installation.
- the method disclosed here for monitoring a suspension element in an elevator installation can be used in different types of elevator installations.
- elevator systems with or without shaft, with or without counterweight, or elevator systems with different gear ratios can be used.
- any suspension means comprising electrically conductive tension members surrounded by an electrically insulating jacket in an elevator installation can be monitored by the method or apparatus disclosed herein.

Description
Die vorliegende Erfindung betrifft eine Aufzugsanlage mit einer Überwachungsvorrichtung für ein Tragmittel, sowie ein Verfahren zur Überwachung zumindest eines Tragmittels in einer Aufzugsanlage.The present invention relates to an elevator installation with a monitoring device for a suspension element, and to a method for monitoring at least one suspension element in an elevator installation.
Bei Aufzugsanlagen wurden zum Tragen und / oder Antreiben einer Aufzugskabine herkömmlicherweise Stahlseile als Tragmittel eingesetzt. Gemäss einer Weiterentwicklung solcher Stahlseile werden auch riemenartige Tragmittel, welche Zugträger und eine um die Zugträger angeordnete Ummantelung aufweisen, eingesetzt. Solche riemenartigen Tragmittel lassen sich jedoch nicht auf herkömmliche Art überwachen, weil die Zugträger, welche eine Bruchlast des Tragmittels bestimmen, nicht sichtbar sind durch die Ummantelung.In elevator systems, steel cables have traditionally been used as support means for carrying and / or driving an elevator car. According to a further development of such steel cables, belt-type suspension elements which have tension members and a jacket arranged around the tension members are also used. However, such belt-like support means can not be monitored in a conventional manner, because the tension members, which determine a breaking load of the suspension element, are not visible through the sheath.
Zur Überwachung solcher Zugträger in riemenartigen Tragmitteln kann ein Prüfstrom an die Zugträger angelegt werden. In dem so gebildeten Stromkreis oder in mehreren so gebildeten Stromkreisen wird ein Stromfluss bzw. eine Stromstärke, eine Spannung, ein elektrischer Widerstand oder eine elektrische Leitfähigkeit gemessen. Anhand einer derart gemessenen Grösse kann auf eine Intaktheit bzw. einen Abnützungsgrad des Tragmittels zurückgeschlossen werden. Verringert sich nämlich der Durchmesser eines Zugträgers durch Brüche einzelner Drähte oder durch metallischen Abrieb, wächst der elektrische Widerstand dieses Zugträgers an.To monitor such tension members in belt-like suspension means, a test current can be applied to the tension members. In the circuit thus formed or in a plurality of circuits thus formed, a current flow, a voltage, an electrical resistance or an electrical conductivity is measured. On the basis of a size measured in this way, it is possible to deduce an integrity or a degree of wear of the suspension element. Namely, reduces the diameter of a tension member by fractures of individual wires or by metallic abrasion, the electrical resistance of this tension member increases.
Das Patent
Bei einer solchen im Stand der Technik beschriebenen Überwachungsmethode kann allerdings nur eine generelle Aussage über den Zustand eines Tragmittels gemacht werden. Es ist daher wünschenswert, eine detailliertere Überwachung von ummantelten Zugträgern in Tragmitteln zu Verfügung zu haben, um eine situationsgerechte Reaktion auslösen zu können.With such a monitoring method described in the prior art, however, only a general statement can be made about the condition of a suspension element. It is therefore desirable to have a more detailed monitoring of sheathed tension members in support means in order to be able to trigger an appropriate reaction.
Es ist daher eine Aufgabe der vorliegenden Erfindung, ein Verfahren zur Überwachung eines Tragmittels in einer Aufzugsanlage zur Verfügung zu stellen, welches eine präzise Aussage über den Zustand des Tragmittels zulässt. Zudem soll das Verfahren mit kostengünstigen Mitteln durchführbar sein. Es ist zudem eine Aufgabe der vorliegenden Erfindung, eine Aufzugsanlage mit einem Tragmittel zur Verfügung zu stellen, wobei in der Aufzugsanlage ein solches Verfahren durchführbar ist.It is therefore an object of the present invention to provide a method of monitoring a suspension in an elevator system to provide, which allows a precise statement about the state of the suspension means. In addition, the process should be feasible with cost-effective means. It is also an object of the present invention to provide an elevator installation with a suspension element, wherein such a method can be carried out in the elevator installation.
Zur Lösung dieser Aufgabe wird zunächst ein Verfahren zur Überwachung zumindest eines Tragmittels in einer Aufzugsanlage vorgeschlagen. Das Tragmittel umfasst elektrisch leitende Zugträger, welche von einem elektrisch isolierenden Mantel umgeben sind. Das Verfahren umfasst folgende Schritte:
- Überwachen eines elektrischen Widerstandes der Zugträger, wobei durch eine Überwachungsvorrichtung zumindest zwei der Zustände: unterbrochener Zugträger,
- geerdeter Zugträger, und beschädigter Zugträger feststellbar sind;
- Auswerten der festgestellten Zustände der Zugträger, wobei die Zustände einem Wamzustand zugeordnet werden; und
- Weiterbetreiben oder Weiterbetreiben unter Absetzung einer Vorwarnung oder Ausserbetriebnehmen der Aufzugsanlage unter Berücksichtigung des Wamzustandes.
- Monitoring an electrical resistance of the tensile carriers, wherein by a monitoring device at least two of the states: interrupted tensile carrier,
- grounded tension members, and damaged tension members are lockable;
- Evaluating the detected states of the train carriers, the states being assigned to a word state; and
- Continue or continue operating by canceling an advance warning or taking the elevator system out of service, taking into account the warning status.
Ein solches Verfahren hat den Vorteil, dass eine situationsgerechte Reaktion auf die unterschiedlichen Zustände des Tragmittels ermöglicht wird. Durch das Aufteilen in drei verschiedene geschädigte Zustände der Zugträger anhand einer Veränderung der elektrischen Charakteristika der Zugträger ist es möglich, durch entsprechende Gewichtung dieser Zustände einem Tragmittel bzw. allen Tragmitteln einer Aufzugsanlage einen Wamzustand zuzuordnen. Ein solcher Warnzustand kann wiederum auf einfache Art und Weise dazu benützt werden, eine entsprechende Reaktion situationsgerecht auszulösen. Somit erlaubt es dieses Verfahren, den Zustand eines Tragmittels genauer einzuschätzen und somit unnötige Ausserbetriebnahmen der Aufzugsanlage zu vermeiden bzw. gefährliches Weiterbetreiben der Aufzugsanlage zu verhindern.Such a method has the advantage that a situation-appropriate reaction to the different states of the suspension element is made possible. By dividing it into three different damaged states of the tension members on the basis of a change in the electrical characteristics of the tension members, it is possible to assign a weighting state to a suspension element or all suspension elements of an elevator installation by appropriate weighting of these states. Such a warning state can in turn be used in a simple manner to trigger a corresponding reaction in accordance with the situation. Thus, this method allows to assess the condition of a suspension more accurate and thus avoid unnecessary shutdown of the elevator system or to prevent dangerous further operation of the elevator system.
In einer vorteilhaften Weiterbildung sind beim Überwachen drei Zustände durch die Überwachungsvorrichtung feststellbar. Dies hat den Vorteil, dass ein Zustand des Tragmittels noch genauer eingeschätzt werden kann, als das dies möglich ist mit lediglich zwei verschiedenen defekten Zuständen der Zugträger.In an advantageous development, three states can be detected by the monitoring device during monitoring. This has the advantage that a condition of the suspension element can be estimated even more accurately than is possible with only two different defective states of the tension members.
In diesem Zusammenhang bedeutet der Begriff "unterbrochener Zugträger" eine Situation, in welcher ein Zugträger an einer Stelle im Wesentlichen so unterbrochen ist, dass im Wesentlichen kein elektrischer Strom über diese Stelle fliessen kann. Der Begriff "geerdeter Zugträger" bedeutet in diesem Zusammenhang, dass ein Zugträger derart Kontakt mit einem geerdeten Element hat, dass elektrischer Strom, welcher an dem Zugträger angelegt wird, im Wesentlichen über dieses geerdete Element abfliesst. Der Begriff "beschädigter Zugträger" bedeutet in diesem Zusammenhang, dass der Zugträger an zumindest einer Stelle eine Beschädigung, beispielsweise in Form einzelner Drahtbrüche oder in Form angerosteter Drähte, aufweist, sodass sich ein elektrischer Widerstand dieses Zugträgers aufgrund dieser beschädigten Stellen verändert. Solche Beschädigungen der Zugträger haben in der Regel den Effekt, dass sich ein elektrischer Widerstand eines betroffenen Zugträgers vergrössert. Ein "beschädigter Zugträger" kann auch dann vorliegen, wenn Aufgrund einer Beschädigung zwei benachbarte Zugträger elektrisch miteinander in Kontakt stehen. Dies ist beispielsweise dann der Fall, wenn das Mantelmaterial zwischen zwei Zugträgern beschädigt ist oder wenn ein gebrochener Draht eines Zugträgers einen benachbarten Zugträger berührt. Solche Querschlüsse zwischen Zugträgern haben in der Regel den Effekt, dass sich ein elektrischer Widerstand eines betroffenen Zugträgers verringert.In this context, the term "interrupted tension member" means a situation in which a tension member is substantially interrupted at one location such that substantially no electrical current can flow over that location. The term "grounded tension member" in this context means that a tension member is in contact with a grounded member such that electrical current applied to the tension member substantially drains off this grounded member. The term "damaged tension member" in this context means that the tension member has at least one point of damage, for example in the form of individual wire breaks or in the form of rusted wires, so that an electrical resistance of this tension member changes due to these damaged areas. Such damage to the tension members usually have the effect of increasing the electrical resistance of an affected tension member. A "damaged tension member" may also be present if, due to damage, two adjacent tension members are in electrical contact with each other. This is the case, for example, when the jacket material between two tension members is damaged or when a broken wire of a tension member contacts an adjacent tension member. Such cross-connections between tension members usually have the effect of reducing the electrical resistance of an affected tension member.
Diese drei unterschiedenen defekten Zustände eines Zugträgers sind auf einfache Art und Weise durch eine Bestimmung eines elektrischen Widerstandes des Zugträgers feststellbar. Strebt der elektrische Widerstand eines Zugträgers gegen unendlich, liegt ein unterbrochener Zugträger vor. Strebt der elektrische Widerstand des Zugträgers gegen Null, so liegt hingegen ein geerdeter Zugträger vor. Ändert sich der elektrische Widerstand eines Zugträgers, so liegt ein beschädigter Zugträger mit zumindest einer beschädigten Stelle vor.These three different defective states of a tension member can be determined in a simple manner by determining an electrical resistance of the tension member. If the electrical resistance of a tension member tends to infinity, there is an interrupted tension member. If the electrical resistance of the tension member tends towards zero, then there is a grounded tension member. If the electrical resistance of a tension member changes, then there is a damaged tension member with at least one damaged point.
In einer beispielhaften Ausführungsform werden beim Auswerten sowohl jedem einzelnen Tragmittel mit allen dazugehörigen Zugträgern als auch einer Summe aller Tragmittel in der Aufzugsanlage mit allen dazugehörigen Zugträgern je einen Wamzustand zugeordnet. Ein solches Verfahren hat den Vorteil, dass sowohl gefährliche Situationen aufgrund einzelner defekter Tragmittel erkannt werden, wie auch gefährliche Situationen aufgrund einer Summe von Defekten in verschiedenen Tragmitteln einer Aufzugsanlage. So können beispielsweise kleine Defekte in je einem von drei Tragmitteln einer Aufzugsanlage einen gefährlichen Zustand darstellen, obwohl das einzelne Tragmittel für sich alleine betrachtet noch nicht einem gefährlichen Zustand zugeordnet werden müsste. Andererseits kann durch ein solches Verfahren eine gefährliche Situation erkannt werden, in welcher nur eines von mehreren Tragmitteln einer Aufzugsanlage Defekte aufweist, dafür aber so gravierende Defekte, dass eine gefährliche Situation für die gesamte Aufzugsanlage vorliegt. Würde man in einer solchen Situation nur die Gesamtheit der Defekte aller Tragmittel betrachten, würde diese Situation nicht richtig eingeschätzt werden können.In an exemplary embodiment, each evaluating each individual support means with all associated tension members as well as a sum of all support means in the elevator system with all associated tension members each assigned a Wamzustand. Such a method has the advantage that both dangerous situations due to individual defective suspension means are recognized, as well as dangerous situations due to a sum of defects in various suspension elements of an elevator installation. For example, small defects in each one of three Carrying means of a lift system represent a dangerous condition, although the individual suspension means considered alone would not have to be assigned to a dangerous condition. On the other hand, by such a method, a dangerous situation can be detected, in which only one of several support means of a lift system has defects, but so serious defects that a dangerous situation for the entire elevator system is present. If, in such a situation, one would only consider the totality of the defects of all the means of suspension, this situation would not be able to be correctly assessed.
In einer beispielhaften Ausführungsform ist für das Weiterbetreiben bzw. Ausserbetriebnehmen der Aufzugsanlage ein schwerwiegendster Wamzustand, ausgewählt aus dem schwerwiegendsten Wamzustand jedes einzelnen Tragmittels und dem Wamzustand der Summe aller Tragmittel, massgebend. Dadurch wird sichergestellt, dass jede Art von gefährlichen Situationen erkannt werden kann.In an exemplary embodiment, for the continued operation or decommissioning of the elevator installation is a most serious Wamzustand selected from the most serious Wamzustand each support means and the Wamzustand the sum of all suspension means, authoritative. This ensures that any kind of dangerous situation can be detected.
In einer beispielhaften Ausführungsform können den Zugträgern zumindest die Warnzustände
- kein Fehler
Fehler 1. GradesFehler 2. Grades
- no mistake
- 1st degree error
- 2nd degree error
In einer beispielhaften Ausführungsform führt beim Weiterbetreiben oder Weiterbetreiben unter Absetzung einer Vorwarnung oder Ausserbetriebnehmen der Aufzugsanlage der Wamzustand kein Fehler zum Weiterbetreiben der Aufzugsanlage, der Wamzustand Fehler 1. Grades zum Weiterbetreiben unter Absetzung einer Vorwarnung, und der Wamzustand Fehler 2. Grades zur Ausserbetriebnahme des Aufzuges.In an exemplary embodiment, upon continuing to drive or continue operating the elevator system, the warning state will not cause the elevator system to continue driving, the warning state of first degree error to continue driving with a warning being canceled, and the warning state of the second degree error to shut down the elevator ,
In einer beispielhaften Ausführungsform führt beim Auswerten ein unterbrochener Zugträger oder ein geerdeter Zugträger zu einem schwerwiegenderen Wamzustand als ein beschädigter Zugträger. Der Vorteil einer derartigen beispielhaften Gewichtung der verschiedenen Defekte der Zugträger liegt darin, dass je nach Beschaffenheit desIn an exemplary embodiment, when evaluated, an interrupted tensile member or a grounded tensile member results in a more severe weighing condition than a damaged tensile member. The advantage of such an exemplary weighting of the various defects of the tension members is that, depending on the nature of the
Tragmittels situationsgerecht auf Defekte der Zugträger reagiert werden kann.Tragmittels can be responded to the situation of defects in the tension members.
In einer beispielhaften Ausführungsform wird einem Tragmittel mit einem unterbrochenen Zugträger oder einem geerdeten Zugträger in jedem Fall ein Fehler 2. Grades zugeordnet.In an exemplary embodiment, a suspension element with an interrupted tension member or a grounded tension member is assigned a second-order error in each case.
In einer beispielhaften Ausführungsform führt ein Tragmittel mit zumindest einem beschädigten Zugträger dann zu einem Fehler 1. Grades, wenn höchstens ein Zugträger pro Tragmittel einen beschädigten Zugträger aufweist und wenn die Anzahl beschädigter Zugträger kleiner ist als die Anzahl Tragmittel. Zudem führt ein Tragmittel mit zumindest einem beschädigten Zugträger dann zu einem Fehler 2. Grades, wenn mehr als ein Zugträger pro Tragmittel beschädigt ist oder wenn die Anzahl beschädigter Zugträger gleich gross oder grösser ist als die Anzahl Tragmittel. Eine solche beispielhafte Gewichtung der verschiedenen defekten Zustände der Zugträger hat den Vorteil, dass eine Aufzugsanlage bei ungefährlichen Defekten unter Absetzung einer Vorwarnung Weiterbetrieben werden kann, und jedoch bei gefährlichen Defekten der Zugträger auf sichere Art und Weise ausser Betrieb genommen werden kann.In an exemplary embodiment, a support means with at least one damaged tensile carrier then leads to a fault of the first degree if at most one tension member per suspension element has a damaged tension member and if the number of damaged tension members is smaller than the number of suspension elements. In addition, a support means with at least one damaged tensile carrier then leads to a second-degree error if more than one tensile member per suspension element is damaged or if the number of damaged tensile members is equal to or greater than the number of suspension elements. Such an exemplary weighting of the various defective states of the tensile carriers has the advantage that an elevator installation can continue to be operated in the case of non-hazardous defects with the deduction of an advance warning, but can be put out of operation in the event of dangerous defects of the tensile carriers.
In einer beispielhaften Ausführungsform wird beim Ausserbetriebnehmen der Aufzugsanlage eine vordefinierte Position einer Aufzugskabine angefahren, bevor die Aufzugsanlage für weitere Fahrten ausser Betrieb gesetzt wird. Eine solche vordefinierte Position der Aufzugskabine kann beispielsweise der nächste öffentliche Halt ausgehend von einer aktuellen Position der Aufzugskabine sein. Dies hat den Vorteil, dass Passagiere, welche sich zum Zeitpunkt der Feststellung eines schwerwiegenderen Defektes der Tragmittel in der Aufzugskabine befinden, möglichst rasch die Aufzugsanlage verlassen können.In an exemplary embodiment, when the elevator installation is taken out of operation, a predefined position of an elevator car is approached before the elevator installation is put out of operation for further journeys. Such a predefined position of the elevator car can be, for example, the next public stop starting from a current position of the elevator car. This has the advantage that passengers who are in the elevator car at the time of detection of a more serious defect of the suspension means can leave the elevator installation as quickly as possible.
In einer beispielhaften Ausführungsform wird beim Weiterbetreiben unter Absetzung einer Vorwarnung eine für die Aufzugsanlage zuständige Unterhaltsstelle über den festgestellten Zustand der Zugträger oder über den dazu zugeordneten Wamzustand informiert. Dies hat den Vorteil, dass die für die Aufzugsanlage zuständige Unterhaltsstelle einen Service bzw. einen Unterhalt der Aufzugsanlage gemäss dieser Information planen kann.In an exemplary embodiment, upon continuing to operate an advance warning, a maintenance center in charge of the elevator installation is informed of the detected condition of the tension members or of the condition associated therewith. This has the advantage that the maintenance center responsible for the elevator installation can plan a service or maintenance of the elevator installation according to this information.
In einer beispielhaften Ausführungsform umfasst das Verfahren weiter den Schritt:
- Anzeigen eines festgestellten Zustandes der Zugträger oder eines den Tragmitteln zugeordneten Wamzustandes an einer in der Aufzugsanlage angeordneten Anzeigeeinrichtung. Ein solches Verfahren hat den Vorteil, dass ein Aufzugstechniker vor Ort unmittelbar den Zustand der Zugträger bzw. der Tragmittel ablesen kann.
- Displaying a detected state of the tension members or a Wamzustandes associated with the support means on a arranged in the elevator installation display device. Such a method has the advantage that an elevator technician can directly read the condition of the tension members or the suspension elements on site.
Die eingangs gestellte Aufgabe wird zudem gelöst durch eine Aufzugsanlage mit zumindest einem Tragmittel, wobei das Tragmittel elektrisch leitende Zugträger umfasst, welche von einem elektrisch isolierenden Mantel umgeben sind. Die Aufzugsanlage umfasst weiterhin eine dem Tragmittel zugeordnete Überwachungsvorrichtung, wobei in der Aufzugsanlage ein Verfahren, wie es oben beschrieben ist, durchführbar ist.The object stated at the outset is also achieved by an elevator installation with at least one suspension element, wherein the suspension element comprises electrically conductive tension members, which are surrounded by an electrically insulating jacket. The elevator installation further comprises a monitoring device associated with the suspension element, wherein a method as described above can be carried out in the elevator installation.
Das hier offenbarte Verfahren zur Überwachung eines Tragmittels in einer Aufzugsanlage kann in unterschiedlichen Arten von Aufzugsanlagen eingesetzt werden. So können beispielsweise Aufzugsanlagen mit oder ohne Schacht, mit oder ohne Gegengewicht, oder Aufzugsanlagen mit unterschiedlichen Übersetzungsverhältnissen eingesetzt werden. Somit kann jedes Tragmittel, welches elektrisch leitende Zugträger umfasst, welche von einem elektrisch isolierenden Mantel umgeben sind, in einer Aufzugsanlage, mit der hier offenbarten Methode bzw. Vorrichtung überwacht werden.The method disclosed here for monitoring a suspension element in an elevator installation can be used in different types of elevator installations. For example, elevator systems with or without shaft, with or without counterweight, or elevator systems with different gear ratios can be used. Thus, any suspension means comprising electrically conductive tension members surrounded by an electrically insulating jacket in an elevator installation can be monitored by the method or apparatus disclosed herein.
Anhand von Figuren wird die Erfindung symbolisch und beispielhaft näher erläutert. Es zeigen:

Ein loses Ende 1.1 des Tragmittels 1 ist mit einer Kontaktierungsvorrichtung 2 zur temporären oder permanenten elektrischen Kontaktierung der Zugträger und somit zur Überwachung des Tragmittels 1 versehen. Im dargestellten Beispiel ist an beiden Enden 1.1 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, und die Zugträger am anderen Tragmittelende 1.1 sind elektrisch miteinander verbunden. Die Tragmittelenden 1.1 sind von der Zugkraft im Tragmittel 1 nicht mehr belastet, da diese Zugkraft bereits vorgängig über die Tragmittelbefestigungsvorrichtungen 47 in das Gebäude geleitet ist. Die Kontaktierungsvorrichtungen 2 sind also in einem nicht überrollten Bereich des Tragmittels 1 und ausserhalb des belasteten Bereichs des Tragmittels 1 angeordnet.A loose end 1.1 of the
Im Beispiel ist die Kontaktierungsvorrichtung 2 an einem Ende des Tragmittels 1.1 mit einer Überwachungsvorrichtung 3 verbunden. Die Überwachungsvorrichtung 3 verschaltet dabei die Zugträger des Tragmittels 1 als elektrische Widerstände in einer elektrischen Verschaltung zur Bestimmung von elektrischen Widerständen. Die Überwachungsvorrichtung 3 ist zudem mit der Aufzugssteuerung 45 verbunden. Diese Verbindung kann beispielsweise als paralleles Relais oder als BUS-System ausgebildet sein. Dadurch kann ein Signal oder ein Messwert von der Überwachungsvorrichtung 3 an die Aufzugssteuerung 45 übermittelt werden, um den Zustand des Tragmittels 1, wie ermittelt von der Überwachungsvorrichtung 3, in einer Steuerung des Aufzuges 40 zu berücksichtigen.In the example, the contacting

In diesem Beispiel ist das Tragmittel mit Längsrippen auf einer Traktionsseite ausgestattet. Solche Längsrippen verbessern ein Traktionsverhalten des Tragmittels 1 auf der Treibscheibe 43 und erleichtern zudem eine seitliche Führung des Tragmittels 1 auf der Treibscheibe 43. Das Tragmittel 1 kann jedoch auch anders ausgestaltet werden, beispielsweise ohne Längsrippen, oder mit einer anderen Anzahl oder anderen Anordnung der Zugträger 5. Wesentlich für die Erfindung ist es, dass die Zugträger 5 elektrisch leitend ausgestaltet sind.In this example, the suspension element is equipped with longitudinal ribs on a traction side. Such longitudinal ribs improve a traction of the support means 1 on the

Die zweite, dritte und vierte Auswertungstabelle in
In der Auswertungstabelle für ein individuelles Tragmittel wurden die Wamzustände mit dem Zusatz "a" bezeichnet, und in den Auswertungstabellen für Aufzugsanlagen mit mehreren Tragmitteln wurden die Wamzustände mit dem Zusatz "b" ergänzt. In einer beispielhaften Ausführungsform wird in einer Aufzugsanlage mit mehreren Tragmitteln sowohl ein Wamzustand für jedes einzelne Tragmittel ermittelt wie auch ein Wamzustand für die gesamte Aufzugsanlage. Dabei hat der Wamzustand für jedes einzelne Tragmittel den Zusatz "a" und der Wamzustand für die Aufzugsanlage insgesamt hat den Zusatz "b". Massgebend für das Weiterbetreiben bzw. ausser Betrieb nehmen der Aufzugsanlage ist nun der schwerwiegendste Wamzustand. Dies kann sowohl ein Wamzustand eines individuellen Tragmittels sein, als auch ein Wamzustand für die gesamte Aufzugsanlage.In the evaluation table for an individual suspension element, the warning states were designated with the suffix "a", and in the evaluation tables for elevator systems with several suspension elements the warning states were supplemented with the suffix "b". In an exemplary embodiment, in a lift installation with a plurality of suspension elements both a warning state for each individual suspension element is determined, as well as a warning state for the entire elevator installation. The Wamzustand for each support means has the addition "a" and the Wamzustand for the elevator system has the addition of "b". Decisive for the continued operation or decommissioning of the elevator system is now the most serious Wamzustand. This can be both a Wamzustand an individual suspension means, as well as a Wamzustand for the entire elevator system.
Beispielsweise führen zwei beschädigte Zugträger in der Auswertungstabelle für eine Aufzugsanlage mit drei Tragmitteln zu einem Fehler 1. Grades. Falls diese zwei beschädigten Zugträger in demselben Tragmittel vorkommen, führt dies in der Betrachtung für dieses individuelle Tragmittel zu einem Fehler 2. Grades (siehe Auswertungstabelle für ein individuelles Tragmittel). Demzufolge kann durch dieses beispielhafte Verfahren unterschieden werden, ob defekte Zugträger gehäuft in einem Tragmittel vorkommen oder nicht. Ein gehäuftes Auftreten von Defekten in einem einzigen Tragmittel ist tendenziell gefährlicher für den Gesamtzustand der Aufzugsanlage und wird daher in diesem Ausführungsbeispiel schwerwiegender gewichtet als ein verteiltes Auftreten von Defekten in Zugträgem, verteilt auf verschiedene Tragmittel.For example, lead two damaged tension members in the evaluation table for a lift system with three support means to a 1st degree error. If these two damaged tension members occur in the same suspension element, this leads to an error of the second degree for this individual suspension element (see evaluation table for an individual suspension element). Accordingly, it can be distinguished by this exemplary method, whether defective tensile carriers frequently occur in a suspension means or not. An increased incidence of defects in a single suspension means tends to be more dangerous to the overall condition of the elevator installation, and is therefore more heavily weighted in this embodiment than a distributed occurrence of defects in tensile structures distributed among various suspension means.
Es versteht sich von selbst, dass im Rahmen der vorliegenden Erfindung eine Vielzahl weiterer Auswertungstabellen realisierbar sind. Die in
