Description

Aufzugsanlage  elevator system
Gegenstand der Erfindung ist eine Aufzugsanlage und insbesondere eine Ausgestaltung einer Befestigung eines Tragmittels in der Aufzugsanlage. The invention relates to an elevator installation and in particular an embodiment of a fastening of a suspension element in the elevator installation.
Bei manchen Aufzugsanlagen werden riemenförmige Tragmittel eingesetzt. Solche Tragmittel umfassen im Allgemeinen mehrere aus Stahldrähten bestehende Zugträger, welche die von dem Tragmittel aufzunehmenden Zugkräfte aufnehmen. Die Zugträger sind im Allgemeinen von einem Mantel aus Kunststoff umgeben. In some elevator systems belt-shaped suspension means are used. Such support means generally comprise a plurality of steel wires existing tension members which receive the tensile forces to be absorbed by the support means. The tension members are generally surrounded by a plastic sheath.
Solche Tragmittel sind innerhalb einer Aufzugsanlage ein sicherheitsrelevantes Bauteil. Aus diesem Grund werden Prüfeinheiten in Aufzugsanlagen eingesetzt, welche insbesondere den mechanischen Zustand der Zugträger überprüfen. Schäden an den die Kräfte aufnehmenden Zugträgenr sollen dadurch frühzeitig erkannt werden können. Somit kann das Tragmittel bei einer Beschädigung ausgewechselt werden, um ein Versagen der Aufzugsanlage zu verhindern. Such suspension means are within a lift installation a safety-relevant component. For this reason, test units are used in elevator systems, which in particular check the mechanical condition of the tension members. Damage to the tensile forces absorbing the forces should thus be detected early. Thus, the support means can be replaced in the event of damage in order to prevent a failure of the elevator installation.
Die elektrisch leitenden Zugträger sind von dem elektrisch isolierenden Mantel aus Kunststoff umgeben. Zur Durchführung einer Prüfung des Zustandes der Zugträger werden üblicherweise die Zugträger elektrisch kontaktiert, und mit Hilfe eines durch die Zugträger geleiteten elektrischen Prüfstromes wird ein Zustand der Zugträger festgestellt. Dabei deuten Veränderungen, insbesondere eine Erhöhung des elektrischen Widerstandes der Zugträger, auf eine Verschlechterung eines Zustandes der Zugträger hin. Um die einzelnen Zugträger zuverlässig überprüfen zu können, ist es wichtig, dass die Zugträger untereinander nicht in elektrischem Kontakt stehen. Solche elektrischen Kurzschlüsse zwischen Zugträgern eines Tragmittels können beispielsweise an Stellen auftreten, an denen das Tragmittel eingeklemmt wird. The electrically conductive tension members are surrounded by the electrically insulating jacket made of plastic. To carry out a test of the condition of the tension members, the tension members are usually electrically contacted, and with the aid of an electrical test current passed through the tension members, a condition of the tension members is determined. In this case, changes, in particular an increase in the electrical resistance of the tension members, indicate a deterioration in a state of the tension members. In order to reliably check the individual tension members, it is important that the tension members are not in electrical contact with each other. Such electrical short circuits between tension members of a suspension element can occur, for example, at points at which the suspension element is clamped.
Eine Aufgabe der vorliegenden Erfindung besteht darin, eine Aufzugsanlage zur Verfügung zu stellen, bei welcher zuverlässig verhindert wird, dass ummantelte An object of the present invention is to provide an elevator installation which reliably prevents sheathed
Zugträger des Tragmittels untereinander elektrisch kurzgeschlossen sind. Die Tensile carriers of the suspension element are electrically short-circuited with each other. The
Aufzugsanlage soll zudem kostengünstig und einfach zu installieren sein. Zur Lösung dieser Aufgabe wird eine Aufzugsanlage mit einer Kabine und einem Tragmittel vorgeschlagen. Dabei ist die Kabine vom Tragmittel zumindest teilweise getragen. Das Tragmittel umfasst mehrere parallel zueinander angeordnete elektrisch leitende Zugträger, welche im Wesentlichen von einem Mantel umhüllt sind. Das Tragmittel weist eine erste Seite und eine zweite Seite auf. Das Tragmittel ist an Tragmittelbefestigungsvorrichtungen befestigt, wobei die Lift system should also be inexpensive and easy to install. To solve this problem, an elevator installation with a cabin and a suspension element is proposed. The cabin is at least partially supported by the support means. The support means comprises a plurality of mutually parallel electrically conductive tension members, which are substantially surrounded by a jacket. The support means has a first side and a second side. The suspension element is attached to suspension means fastening devices, wherein the
Tragmittelbefestigungsvorrichtungen jeweils ein Gehäuse und ein Klemmelement umfassen. Das Gehäuse und das Klemmelement weisen Klemmflächen auf, zwischen welchen das Tragmittel eingeklemmt ist. Dabei ist zumindest zwischen einer Seite des Tragmittels und den daran angeordneten Klemmflächen ein elektrisch isolierendes Material angeordnet, welches das Tragmittel elektrisch von dem Gehäuse bzw. dem Klemmelement trennt.  Supporting means fastening devices each comprise a housing and a clamping element. The housing and the clamping element have clamping surfaces, between which the support means is clamped. In this case, an electrically insulating material is arranged at least between one side of the support means and the clamping surfaces arranged thereon, which electrically separates the support means from the housing or the clamping element.
Eine solche Aufzugsanlage hat zunächst den Vorteil, dass herkömmliche Keilschlösser als Tragmittelbefestigungsvorrichtungen verwendet werden können. Die herkömmlichen Tragmittelbefestigungsvorrichtungen und das darin eingelegte Tragmittel werden lediglich durch das elektrisch isolierende Material ergänzt. Dadurch wird sichergestellt, dass bei einem möglicherweise auftretenden Kontakt zwischen den Zugträgern und der Tragmittelbefestigungsvorrichtung keine elektrischen Brücken zwischen den Zugträgern entstehen, und dass keine Erdung der Zugträger über die Such an elevator installation initially has the advantage that conventional wedge locks can be used as suspension means fastening devices. The conventional suspension fixing means and the support means inserted therein are supplemented only by the electrically insulating material. This ensures that arise in a possibly occurring contact between the tension members and the support means fastening device no electrical bridges between the tension members, and that no grounding of the tension members on the
Tragmittelbefestigungsvorrichtung entsteht. Somit bleiben die Zugträger des Tragmittels elektrisch voneinander isoliert, auch wenn der Mantel auf einer Seite des Tragmittels durchgescheuert ist. Ein solches elektrisch isolierendes Material ist kostengünstig herzustellen und einfach in einer Aufzugsanlage zu installieren. Zudem können bestehende Aufzugsanalgen mit einem solchen elektrisch isolierenden Material nachgerüstet werden.  Tragmittelbefestigungsvorrichtung arises. Thus, the tension members of the support means remain electrically isolated from each other, even if the jacket is worn through on one side of the support means. Such an electrically insulating material is inexpensive to manufacture and easy to install in an elevator installation. In addition, existing elevator systems can be retrofitted with such an electrically insulating material.
In einem vorteilhaften Ausführungsbeispiel ist die erste Seite des Tragmittels eine Traktionsseite, welche in Kontakt steht mit einer Treibscheibe eines Antriebes. Die zweite Seite des Tragmittels ist eine Rückseite. Dabei ist das elektrisch isolierende Material zwischen der Rückseite des Tragmittels und dem Gehäuse bzw. dem In an advantageous embodiment, the first side of the support means is a traction side, which is in contact with a traction sheave of a drive. The second side of the suspension element is a rear side. In this case, the electrically insulating material between the back of the support means and the housing or the
Klemmelement angeordnet. Eine derartige Anordnung des elektrisch isolierenden Materiales ist vorteilhaft, weil beobachtet wurde, dass der in der Regel dünner ausgestaltete Mantel auf der Rückseite des Tragmittels schneller durchscheuert als der in der Regel dicker ausgestaltete Mantel auf der Traktionsseite des Tragmittels. Somit kann es in diesem Ausführungsbeispiel genügen, lediglich eine Seite des Tragmittels durch das elektrisch isolierende Material von der Tragmittelbefestigungsvorrichtung elektrisch zu isolieren. Clamping element arranged. Such an arrangement of the electrically insulating material is advantageous because it has been observed that the usually thinner configured jacket on the back of the support means penetrates faster than in usually thicker configured coat on the traction side of the suspension element. Thus, in this embodiment, it may be sufficient to electrically isolate only one side of the support means by the electrically insulating material from the suspension fastener.
In einem weiteren vorteilhaften Ausführungsbeispiel ist zwischen beiden Seiten des Tragmittels und dem Gehäuse bzw. dem Klemmelement ein elektrisch isolierendes Material angeordnet. Eine solche Anordnung ist vorteilhaft, wenn zu erwarten ist, dass entweder der Mantel auf der Rückseite des Tragmittels oder der Mantel auf der In a further advantageous embodiment, an electrically insulating material is arranged between both sides of the suspension element and the housing or the clamping element. Such an arrangement is advantageous when it is expected that either the jacket on the back of the suspension element or the jacket on the
Traktionsseite des Tragmittels im Gebrauch geschädigt werden könnte. Traction side of the suspension element could be damaged in use.
In einer vorteilhaften Ausführungsform sind auf der Traktionsseite des Tragmittels Längsrippen ausgebildet. Solche Längsrippen haben den Vorteil, dass eine Traktion zwischen dem Tragmittel und einer Treibscheibe erhöht ist, und dass zudem ein In an advantageous embodiment, longitudinal ribs are formed on the traction side of the suspension element. Such longitudinal ribs have the advantage that a traction between the support means and a traction sheave is increased, and that in addition a
Durchscheuern des Mantels auf der Traktionsseite bis auf die Zugträger wirksam verhindert wird. Chafing of the jacket on the traction side until it is effectively prevented on the tension members.
Das elektrisch isolierende Material kann auf verschiedene Art und Weise ausgebildet sein. Es kann beispielsweise als durchgehende Schicht oder aber als auf einer Fläche verteilten Teilstücken ausgebildet sein. Wesentlich dabei ist es, dass das Tragmittel bzw. die Zugträger wirksam von den Klemmflächen elektrisch isoliert sind. The electrically insulating material may be formed in various ways. It may be formed, for example, as a continuous layer or as portions distributed on a surface. It is essential that the suspension element or the tension members are effectively electrically isolated from the clamping surfaces.
In einem vorteilhaften Ausführungsbeispiel ist das elektrisch isolierende Material als Folie ausgebildet. In einer vorteilhaften Weiterbildung ist die Folie zwischen dem Tragmittel und dem Gehäuse bzw. dem Klemmelement eingelegt und eingeklemmt. Eine solche Folie hat den Vorteil, dass sie einfach in bestehende Aufzugsanlagen nachgerüstet werden kann, und dass sie keinerlei Veränderung bei einer Herstellung der In an advantageous embodiment, the electrically insulating material is formed as a film. In an advantageous embodiment, the film between the support means and the housing or the clamping element is inserted and clamped. Such a film has the advantage that it can be easily retrofitted into existing elevator systems, and that they no change in a production of the
Tragmittelbefestigungsvorrichtung verlangt. Tragmittelbefestigungsvorrichtung requires.
In einem alternativen vorteilhaften Ausführungsbeispiel ist das elektrisch isolierende Material als Klebeband ausgebildet. In einer vorteilhaften Weiterbildung ist das In an alternative advantageous embodiment, the electrically insulating material is designed as an adhesive tape. In an advantageous development that is
Klebeband auf dem Tragmittel und / oder auf dem Gehäuse bzw. dem Klemmelement aufgeklebt. Ein solches Klebeband hat ebenfalls den Vorteil, dass es auf einfache Art und Weise in bereits bestehende Aufzugsanlagen nachgerüstet werden kann. Zudem bietet ein Klebeband den Vorteil, dass das elektrisch isolierende Material bei einer Installation der Aufzugsanlage weniger leicht von seiner vorgesehenen Position wegrutschen kann. Adhesive tape adhered to the support means and / or on the housing or the clamping element. Such an adhesive tape also has the advantage that it can be retrofitted in a simple manner in already existing elevator systems. It also offers a Adhesive tape has the advantage that the electrically insulating material is less able to slip away from its intended position during installation of the elevator installation.
In einem weiteren vorteilhaften Ausführungsbeispiel ist das elektrisch isolierende Material als Beschichtung ausgebildet. In einer vorteilhaften Weiterbildung ist die Beschichtung auf dem Gehäuse bzw. dem Klemmelement aufgebracht. Eine solche Beschichtung hat den Vorteil, dass sie immer an ihrer vorgesehenen Position verbleibt, und dass dazu keine separaten Installationsschritte bei einer Installation des Aufzuges notwendig sind. Dadurch können bei der Installation der Aufzugsanlage weniger Fehler auftreten. Eine Beschichtung hat zudem weiterhin den Vorteil, dass In a further advantageous embodiment, the electrically insulating material is formed as a coating. In an advantageous development, the coating is applied to the housing or the clamping element. Such a coating has the advantage that it always remains in its intended position, and that this no separate installation steps in an installation of the elevator are necessary. As a result, fewer errors may occur during the installation of the elevator installation. A coating also has the further advantage that
Oberflächeneigenschaften unabhängig vom Material der Surface properties independent of the material of the
Tragmittelbefestigungsvorrichtung gewählt werden können. So kann beispielsweise ein Beschichtungsmaterial gewählt werden, welches eine andere Oberflächenrauheit als die Tragmittelbefestigungsvorrichtung ohne Beschichtung aufweist.  Tragmittelbefestigungsvorrichtung can be selected. Thus, for example, a coating material can be selected which has a different surface roughness than the suspension means fastening device without coating.
In einer vorteilhaften Weiterbildung ist die Beschichtung eine Pulverbeschichtung oder ein Nasslack oder eine keramische Beschichtung oder eine Emaillierung oder eine Teflonbeschichtung. Die Art der Beschichtung kann je nach Beschaffenheit der In an advantageous development, the coating is a powder coating or a wet paint or a ceramic coating or an enamel coating or a Teflon coating. The type of coating can vary depending on the nature of the
Aufzugsanlage, des Tragmittels, und der Tragmittelbefestigungsvorrichtung gewählt bzw. angepasst werden. Elevator system, the support means, and the suspension means fastening device are selected or adapted.
In einem vorteilhaften Ausführungsbeispiel weist die Beschichtung eine Schichtdicke von 5 bis 1000 Mikrometer, bevorzugt von 10 bis 500 Mikrometer, besonders bevorzugt von 15 bis 300 Mikrometer auf. Dabei kann je nach Beschichtungsart eine kleinere oder grösser Schichtdicke erforderlich sein, um die gewünschte elektrisch isolierende Funktion unter allen Umständen zu gewährleisten. In an advantageous embodiment, the coating has a layer thickness of 5 to 1000 microns, preferably from 10 to 500 microns, more preferably from 15 to 300 microns. Depending on the type of coating, a smaller or larger layer thickness may be required in order to ensure the desired electrically insulating function under all circumstances.

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 The elevator installation 40 illustrated schematically and by way of example in FIG. 1 includes an elevator cage 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 suspension element 1 and thus moves the elevator cage 41 and the counterweight 42 counter to one another , The drive motor 44 is controlled by an elevator control 45. The cabin 41 is designed to accommodate people and / or goods and between floors of a
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 Transport 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 suspension element 1 is at a first
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, als sich Kabine 41 bzw. Gegengewicht 42 bewegen. Im Beispiel beträgt der Umhängefaktor 2: 1. Fixed suspension means fastening device 47, and then first performed to 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 at a higher speed via the drive 43, 44, in accordance with a transfer factor, than the car 41 or counterweight 42 move. in the Example is the shoulder factor 2: 1.

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 A loose end 1.1 of the suspension element 1 is provided with a contacting device 2 for temporary or permanent contacting and monitoring 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.
