It also has a holding structure to be arranged at one end of the travel path, on which the measuring tape is fixed in a fixed position relative to the travel path by means of a fastening device is attached. The holding structure is intended in particular to be arranged at an upper end of the travel path. According to the invention, a receiving device for receiving a measuring tape supply is arranged on the holding structure, with a measuring tape piece of the measuring tape supply being provided to be arranged upwards along the extension piece when the travel path is extended by one extension piece.

  • the measuring tape of the measuring tape arrangement is made in one piece, ie consists of only one piece, it must have a length from the start that can cover the final height of the elevator shaft and thus the final length of the travel path of the elevator car. As long as the traversing path does not extend beyond its final length, there is a supply of measuring tape that is required in subsequent extensions of the traversing path. With each extension of travel, a length of measuring tape from the supply of measuring tape is placed along an extension of travel; the supply of measuring tape thus becomes smaller with each extension of the traverse path.
  • a receiving device for receiving the described supply of measuring tape on the holding structure makes it possible to supply the supply of measuring tape simply and quickly after arranging the measuring tape along the current travel path and to store it during the subsequent operation of the elevator system. If the travel path is extended upwards, the support structure must also be moved upwards, which is usually done by a fitter. In this case, the fitter also has direct access to the supply of measuring tape due to the arrangement of the recording device on the holding structure, which also enables simple and quick installation.
  • the storage of the measuring tape supply on the support structure has the additional advantage that only a small part of the measuring tape has to be removed from the container, so that a very large part can remain in the container and thus protected from damage.
  • the location information that varies along the measuring tape can be embodied in particular as locally varying magnetizations of a magnetic tape, which are arranged in a so-called pseudo-random code. By detecting the pseudo-random code, the position of the elevator car relative to the measuring tape can be unequivocally inferred.

  • the fastening device has a clamping plate which can be fixed to the holding structure in such a way that the measuring tape is clamped between the clamping plate and the holding structure.

This effectively prevents the measuring tape from twisting when the travel path is lengthened. Detaching the measuring tape from the holding structure is therefore understood to mean that the holding structure after detaching can be shifted relative to the measuring tape.
  • the lengthening of the travel distance can be repeated. In particular, it is repeated until the travel path extends over the entire elevator shaft of the completed building.

  • the measuring tape When using the measuring tape arrangement according to the invention and when carrying out the method according to the invention, the measuring tape is installed from bottom to top. One end of the measuring tape is thus arranged at the lower end of the travel path and thus of the elevator shaft, and the measuring tape is then guided upwards. A supply of measuring tape is thus located at the support structure at the upper end of the travel path, as described.

This would not be the case if the supply of measuring tape remained at the bottom of the hoistway and an end of the measuring tape located at the top of the travel was displaced upwardly as the travel lengthened.

Description

Die Erfindung betrifft eine Messbandanordnung für einen Einsatz in einer Aufzuganlage zum Bestimmen einer Position einer Aufzugkabine entlang eines Verfahrwegs gemäss dem Oberbegriff des Anspruchs 1 und ein Verfahren zum Installieren und Betreiben einer Aufzuganlage in einem Aufzugschacht eines sich in seiner Bauphase befindenden Gebäudes mit den Merkmalen des Anspruchs 14.The invention relates to a measuring tape arrangement for use in an elevator system for determining a position of an elevator car along a travel path according to the preamble of claim 1 and a method for installing and operating an elevator system in an elevator shaft of a building currently under construction, having the features of the claim 14

Aufzuganlagen verfügen über mindestens eine Aufzugkabine, welche innerhalb eines Aufzugschachts entlang eines vertikal verlaufenden Verfahrwegs zwischen verschiedenen Niveaus oder Stockwerken verfahren werden kann. Die Aufzugkabine wird dabei mithilfe eines Antriebs verlagert und der Antrieb wird von einer Steuerung gesteuert. Um die Aufzugkabine präzise verlagern und beispielsweise mit ihrem Boden bündig zu einem Boden eines Stockwerks stoppen zu können, müssen der Steuerung Informationen über die aktuelle Position der Aufzugkabine vorliegen.Elevator systems have at least one elevator car, which can be moved within an elevator shaft along a vertical travel path between different levels or floors. The elevator car is shifted with the help of a drive and the drive is controlled by a controller. In order to be able to move the elevator car precisely and, for example, to be able to stop it flush with the floor of a floor, the controller must have information about the current position of the elevator car.

Um derartige Informationen bereitstellen zu können, ist in der Aufzuganlage üblicherweise ein spezielles Messsystem vorgesehen. Beispielsweise ist in der EP 1 412 274 B1 eine Aufzuganlage mit einem Messsystem zur Ermittlung der absoluten Kabinenposition beschrieben.In order to be able to provide such information, a special measuring system is usually provided in the elevator installation. For example, in the EP 1 412 274 B1 describes an elevator system with a measuring system for determining the absolute car position.

Bei einem bestimmten Typ von Messsystem ist ein Band entlang des Verfahrwegs der Aufzugkabine angeordnet. Auf diesem Band sind variierende Ortsinformationen gespeichert. Beispielsweise kann das Band als Magnetband ausgebildet sein, auf dem die Ortsinformationen als lokal variierende Magnetisierungen gespeichert sind. An der Aufzugkabine kann eine Auslesevorrichtung vorgesehen sein, mithilfe derer diese Ortsinformationen ausgelesen werden können. Die Ortsinformationen können dann ausgewertet und an die Steuerung der Aufzuganlage weitergeleitet werden, sodass die Steuerung basierend auf diesen Ortsinformationen auf die aktuelle Position der Aufzugkabine relativ zu dem Band rückschliessen kann. Das Band wird daher hierin als Messband bezeichnet.In one type of measurement system, a tape is placed along the travel path of the elevator car. Varying location information is stored on this tape. For example, the tape can be designed as a magnetic tape on which the location information is stored as locally varying magnetizations. A readout device can be provided on the elevator car, with the aid of which this location information can be read out. The location information can then be evaluated and forwarded to the controller of the elevator installation, so that the controller can draw conclusions about the current position of the elevator car relative to the belt based on this location information. The tape is therefore referred to herein as referred to as a measuring tape.

Die Messbandanordnung verfügt über ein entlang des Verfahrwegs anzuordnendes Messband, wobei entlang des Messbands variierende Ortsinformationen gespeichert sind, anhand derer eine aktuelle Position relativ zu dem Messband ermittelbar ist. Sie weist ausserdem eine an einem oberen Ende des Verfahrwegs anzuordnende Haltestruktur auf, an welcher mittels einer Befestigungsvorrichtung das Messband an einer fixen Position relativ zu dem Verfahrweg befestigt ist.In the applicant's patent application with the international publication number WO 2019/141726 A1 describes a measuring tape arrangement for use in an elevator system for determining a position of an elevator car along a travel path, the travel path no longer changing after installation and initial commissioning of the elevator system.

In anderen Worten lassen sich im Folgenden beispielsweise unter Bezugnahme auf die Messbandanordnung beschriebenen Merkmale auch als Verfahrensschritte implementieren, und umgekehrt.In contrast, it is in particular the object of the invention to propose a measuring tape arrangement and a method for installing and operating an elevator system, which can be used particularly advantageously in a building that is in its construction phase. In particular, the installation of the measuring tape arrangement should be made possible with less expenditure of time and/or costs. According to the invention, this object is achieved with a measuring tape arrangement having the features of claim 1 and a method having the features of claim 14. The exemplary embodiments described below relate equally to the measuring tape arrangement and the method. In other words, features described below, for example with reference to the measuring tape arrangement, can also be implemented as method steps, and vice versa.

Die erfindungsgemässe Messbandanordnung für einen Einsatz in einer Aufzuganlage zum Bestimmen einer Position einer Aufzugkabine entlang eines Verfahrwegs verfügt über ein entlang des Verfahrwegs anzuordnendes, einstückiges Messband, wobei entlang des Messbands variierende Ortsinformationen gespeichert sind, anhand derer eine aktuelle Position relativ zu dem Messband ermittelbar ist. Sie weist ausserdem eine an einem Ende des Verfahrwegs anzuordnende Haltestruktur auf, an welcher mittels einer Befestigungsvorrichtung das Messband an einer fixen Position relativ zu dem Verfahrweg befestigt ist. Die Haltestruktur ist insbesondere dazu vorgesehen, an einem oberen Ende des Verfahrwegs angeordnet zu werden. Erfindungsgemäss ist an der Haltestruktur eine Aufnahmevorrichtung zum Aufnehmen eines Messbandvorrats angeordnet, wobei ein Messbandstück des Messbandvorrats dazu vorgesehen ist, bei einer Verlängerung des Verfahrwegs um ein Verlängerungsstück nach oben entlang des Verlängerungsstücks angeordnet zu werden.The measuring tape arrangement according to the invention for use in an elevator system for determining a position of an elevator car along a travel path has a one-piece measuring tape to be arranged along the travel path, with location information varying along the measuring tape being stored, on the basis of which a current position relative to the measuring tape can be determined. It also has a holding structure to be arranged at one end of the travel path, on which the measuring tape is fixed in a fixed position relative to the travel path by means of a fastening device is attached. The holding structure is intended in particular to be arranged at an upper end of the travel path. According to the invention, a receiving device for receiving a measuring tape supply is arranged on the holding structure, with a measuring tape piece of the measuring tape supply being provided to be arranged upwards along the extension piece when the travel path is extended by one extension piece.

Bei Aufzuganlagen, welche in einem sich in seiner Bauphase befindenden Gebäudes eingesetzt werden, wird üblicherweise der Verfahrweg der Aufzugkabine schrittweise nach oben verlängert. Dabei wird mit der Installation und dem Betrieb der Aufzuganlage nicht gewartet, bis das Gebäude vollständig fertiggestellt ist. Vielmehr wird die Aufzuganlage installiert und betrieben, sobald einige Stockwerke des Gebäudes inklusive des Aufzugschachts der Aufzuganlage dieser Stockwerke fertiggestellt sind. Damit kann die Aufzuganlage bereits während der Bauphase des Gebäudes zum vertikalen Transport von Personen und/oder Material genutzt werden. Dadurch können speziell für Transportaufgaben während der Bauphase vorgesehene Aufzüge - beispielsweise solche, die an der Aussenseite des Gebäudes angebracht werden - ganz oder teilweise eingespart werden.In the case of elevator installations which are used in a building which is in the construction phase, the travel path of the elevator car is usually gradually increased upwards. The installation and operation of the elevator system does not wait until the building is completely finished. Rather, the elevator system is installed and operated as soon as a few floors of the building, including the elevator shaft of the elevator system on these floors, have been completed. This means that the elevator system can already be used during the construction phase of the building for the vertical transport of people and/or material. As a result, elevators that are specially provided for transport tasks during the construction phase - for example those that are attached to the outside of the building - can be completely or partially eliminated.

Es wird also zunächst im untersten Abschnitt des Aufzugschachts die Aufzuganlage installiert, also beispielsweise Führungsschienen zum Führen der Aufzugkabine und ggf. eines Gegengewichts an Schachtwänden fixiert, womit ein unterstes Verfahrwegstück für die Aufzugkabine zur Verfügung gestellt wird. Um die Aufzuganlage betreiben zu können, wird ausserdem ein Messband mit variierenden Ortsinformationen entlang des untersten Verfahrwegstücks angeordnet, anhand dessen eine aktuelle Position der Aufzugkabine ermittelt werden kann. Nach Abschluss der Installation der Aufzuganlage im untersten Abschnitt des Aufzugschachts kann die Aufzuganlage in diesem untersten Abschnitt des Aufzugschachts betrieben werden, also die Aufzugkabine entlang des untersten Verfahrwegstücks vertikal verlagert werden.The elevator system is therefore first installed in the lowermost section of the elevator shaft, ie for example guide rails for guiding the elevator car and possibly a counterweight are fixed to the shaft walls, whereby a lowermost travel path piece is made available for the elevator car. In order to be able to operate the elevator system, a measuring tape with varying location information is also arranged along the lowermost travel path piece, on the basis of which a current position of the elevator car can be determined. After completion of the installation of the elevator system in the lowest section of the elevator shaft, the elevator system can be operated in this lowest section of the elevator shaft, ie the elevator car can be vertically displaced along the lowest travel path piece.

Sobald ein weiterer Abschnitt des Gebäudes und damit ein oberhalb des untersten Abschnitts angeordneter zweiter Abschnitt des Aufzugschachts fertig gestellt ist, kann die Aufzuganlage auch in dem genannten zweiten Abschnitt des Aufzugschachts installiert und anschliessend betrieben werden. Dazu müssen beispielsweise Führungsschienen im zweiten Abschnitt des Aufzugschachts fixiert werden. Der Verfahrweg der Aufzugkabine wird damit um ein Verlängerungsstück nach oben verlängert. Um die Aufzugkabinen auch entlang des Verlängerungsstücks verlagern zu können, wird das Messband auch entlang des Verlängerungsstücks angeordnet. Diese beschriebene Verlängerung des Verfahrwegs wird so lange wiederholt, bis das Gebäude fertiggestellt ist, der Aufzugschacht damit seine endgültige Höhe erreicht hat. Die beschriebene Installation der Aufzuganlage kann beispielsweise mit einem Verfahren gemäss der Patentanmeldung der Anmelderin mit der internationalen Veröffentlichungsnummer WO 2019/068469 A1 erfolgen.As soon as a further section of the building and thus a second section of the elevator shaft arranged above the lowest section is completed, the elevator system can also be installed in said second section of the elevator shaft and then operated. These must, for example, guide rails in second section of the elevator shaft to be fixed. The travel path of the elevator car is thus extended upwards by an extension piece. In order to also be able to move the elevator cars along the extension piece, the measuring tape is also arranged along the extension piece. This described extension of the traversing path is repeated until the building is completed and the elevator shaft has thus reached its final height. The described installation of the elevator system can be carried out, for example, using a method according to the applicant's patent application with the international publication number WO 2019/068469 A1 take place.

Da das Messband der Messbandanordnung einstückig ausgeführt ist, also aus nur einem Stück besteht, muss es von Anfang an eine Länge aufweisen, mit der die endgültige Höhe des Aufzugschachts und damit die endgültige Länge des Verfahrwegs der Aufzugkabine abgedeckt werden kann. So lange sich der Verfahrweg nicht über seine endgültige Länge erstreckt, ergibt sich damit ein Messbandvorrat an Messband, der in folgenden Verlängerungen des Verfahrwegs benötigt wird. Bei jeder Verlängerung des Verfahrwegs wird ein Messbandstück des Messbandvorrats entlang eines Verlängerungsstücks des Verfahrwegs angeordnet; der Messbandvorrat wird damit bei jeder Verlängerung des Verfahrwegs kleiner.Since the measuring tape of the measuring tape arrangement is made in one piece, ie consists of only one piece, it must have a length from the start that can cover the final height of the elevator shaft and thus the final length of the travel path of the elevator car. As long as the traversing path does not extend beyond its final length, there is a supply of measuring tape that is required in subsequent extensions of the traversing path. With each extension of travel, a length of measuring tape from the supply of measuring tape is placed along an extension of travel; the supply of measuring tape thus becomes smaller with each extension of the traverse path.

Das erfindungsgemässe Vorsehen einer Aufnahmevorrichtung zum Aufnehmen des beschriebenen Messbandvorrats an der Haltestruktur ermöglicht, den Messbandvorrat nach dem Anordnen des Messbands entlang des aktuellen Verfahrwegs einfach und schnell zu versorgen und während des folgenden Betriebs der Aufzuganlage aufzubewahren. Bei einer Verlängerung des Verfahrwegs nach oben muss auch die Haltestruktur nach oben verlagert werden, was üblicherweise von einem Monteur erledigt wird. Durch die Anordnung der Aufnahmevorrichtung an der Haltestruktur hat der Monteur in diesem Fall auch direkt Zugriff auf den Messbandvorrat, was ebenfalls eine einfache und schnelle Installation ermöglicht. Wenn das Messband aus einem Behälter, beispielsweise einer Kartonbox, entnommen wird, hat die Aufbewahrung des Messbandvorrats an der Haltestruktur den zusätzlichen Vorteil, dass nur ein geringer Teil des Messbands aus dem Behälter entnommen werden muss, ein sehr grosser Anteil damit in dem Behälter verbleiben kann und damit vor Beschädigungen geschützt wird.The inventive provision of a receiving device for receiving the described supply of measuring tape on the holding structure makes it possible to supply the supply of measuring tape simply and quickly after arranging the measuring tape along the current travel path and to store it during the subsequent operation of the elevator system. If the travel path is extended upwards, the support structure must also be moved upwards, which is usually done by a fitter. In this case, the fitter also has direct access to the supply of measuring tape due to the arrangement of the recording device on the holding structure, which also enables simple and quick installation. When the measuring tape is removed from a container, e.g. a cardboard box, the storage of the measuring tape supply on the support structure has the additional advantage that only a small part of the measuring tape has to be removed from the container, so that a very large part can remain in the container and thus protected from damage.

Die entlang des Messbands variierenden Ortsinformationen können insbesondere als lokal variierende Magnetisierungen eines Magnetbands ausgeführt sein, die in einem so genannten Pseudo-Zufallscode angeordnet sind. Durch Erfassen des Pseudozufallscode kann eindeutig auf die Position der Aufzugkabine relativ zum Messband geschlossen werden. Die Informationen können auch als optische Informationen, beispielsweise vergleichbar mit einem Barcode oder einem so genannten QR-Code ausgeführt sein.The location information that varies along the measuring tape can be embodied in particular as locally varying magnetizations of a magnetic tape, which are arranged in a so-called pseudo-random code. By detecting the pseudo-random code, the position of the elevator car relative to the measuring tape can be unequivocally inferred. The information can also be in the form of optical information, for example comparable to a barcode or a so-called QR code.

Das Messband hängt über die Befestigungsvorrichtung an der Haltestruktur nach unten. Es ist auch möglich, dass die Haltestruktur und die Befestigungsvorrichtung als ein gemeinsames Bauteil ausgeführt sind. Es kann an seinem der Befestigungsvorrichtung gegenüberliegenden Ende geführt oder gehalten sind, um ein Schwingen des genannten Endes zu verhindern. An dem genannten Ende ist insbesondere eine Spannvorrichtung, beispielsweise in Form eines Spanngewichts angeordnet, um das Messband unter einer gewissen Spannung zu halten.The measuring tape hangs down over the fastener on the support structure. It is also possible for the holding structure and the fastening device to be designed as a common component. It may be guided or supported at its end opposite the attachment device to prevent swinging of said end. In particular, a tensioning device, for example in the form of a tensioning weight, is arranged at said end in order to keep the measuring tape under a certain tension.

Die Haltestruktur ist insbesondere als eine Art Schiene ausgeführt, die im Aufzugschacht fixiert und damit in einer fixen bzw. ortsfesten Position relativ zum Verfahrweg angeordnet ist. Die Aufnahmevorrichtung zum Aufnehmen des Messbandvorrats ist an die Haltestruktur beispielsweise angeschraubt, angenietet, angeschweisst oder angeklebt. Es ist auch möglich, dass die Haltestruktur und die Aufnahmevorrichtung als ein gemeinsames Bauteil ausgeführt sind.The holding structure is designed in particular as a type of rail that is fixed in the elevator shaft and is therefore arranged in a fixed or stationary position relative to the travel path. The receiving device for receiving the supply of measuring tape is, for example, screwed, riveted, welded or glued to the holding structure. It is also possible for the holding structure and the receiving device to be designed as a common component.

In Ausgestaltung der Erfindung weist die Aufnahmevorrichtung eine Auflagefläche auf, welche so ausgeführt und angeordnet ist, dass sich der Messbandvorrat auf der Auflagefläche nach unten und an der Haltestruktur horizontal abstützen kann. Sie verfügt ausserdem über eine Abschlussfläche, welche so ausgeführt und angeordnet ist, dass ein sich auf der Auflagefläche abstützender Messbandvorrat zumindest teilweise zwischen der Haltestruktur und der Abschlussfläche angeordnet ist. Dies ermöglicht eine sichere Aufnahme des Messbandvorrats bei gleichzeitig einfachem und damit kostengünstigem Aufbau der Aufnahmevorrichtung.In an embodiment of the invention, the receiving device has a support surface which is designed and arranged in such a way that the supply of measuring tape can be supported downwards on the support surface and horizontally on the holding structure. It also has an end surface, which is designed and arranged in such a way that a supply of measuring tape supported on the bearing surface is arranged at least partially between the holding structure and the end surface. This enables the supply of measuring tape to be securely accommodated while at the same time having a simple and therefore cost-effective construction of the accommodation device.

Die Auflagefläche ist insbesondere horizontal und die Abschlussfläche insbesondere vertikal ausgerichtet. Ausserdem schliesst die Abschlussfläche insbesondere direkt an die Auflagefläche an. Eine maximale Erstreckung der Auflagefläche entlang der Haltestruktur ist insbesondere geringer als eine maximale Erstreckung der Abschlussfläche entlang der Haltestruktur, wobei die maximale Erstreckung der Abschlussfläche entlang der Haltestruktur insbesondere oberhalb der Haltestruktur ausgebildet ist. Die Aufnahmevorrichtung ist insbesondere so an der Haltestruktur angeordnet, dass die Abschlussfläche zwischen Haltestruktur und Schachtwand des Aufzugschachts angeordnet ist, an der die Haltestruktur zumindest mittelbar fixiert ist.The support surface is aligned in particular horizontally and the closing surface is aligned in particular vertically. In addition, the closing surface connects in particular directly to the bearing surface. A maximum extension of the bearing surface along the The holding structure is in particular less than a maximum extent of the end surface along the holding structure, the maximum extent of the end surface being formed along the holding structure in particular above the holding structure. The receiving device is arranged on the holding structure in particular in such a way that the closing surface is arranged between the holding structure and the shaft wall of the elevator shaft, on which the holding structure is at least indirectly fixed.

In Ausgestaltung der Erfindung weist die Aufnahmevorrichtung zwei sich gegenüberliegende Seitenwangen auf, welche so ausgeführt und angeordnet sind, dass eine horizontale Verlagerung des Messbandvorrats entlang der Haltestruktur begrenzt ist. Dies ermöglicht eine besonders sichere Aufnahme des Messbandvorrats.In an embodiment of the invention, the receiving device has two opposite side cheeks, which are designed and arranged in such a way that a horizontal displacement of the supply of measuring tape along the holding structure is limited. This enables the measuring tape supply to be picked up particularly securely.

Die Seitenwangen verhindern, dass der Messbandvorrat ohne Beschränkung horizontal entlang der Haltestruktur verschoben werden kann, was zu einem Verlassen der Aufnahmevorrichtung und damit zu einem Herabfallen in den Aufzugschacht führen könnte. Die Seitenwangen schliessen insbesondere seitlich an die Abschlussfläche an und sind insbesondere in einem rechten Winkel zur Abschlussfläche orientiert. Sie erstrecken sich insbesondere von der Abschlussfläche in Richtung Haltestruktur und sind insbesondere nur oberhalb der Haltestruktur angeordnet.The side walls prevent the supply of measuring tape from being displaced horizontally along the support structure without restriction, which could result in it leaving the holding device and thus falling into the elevator shaft. In particular, the side walls adjoin the end face laterally and are oriented in particular at a right angle to the end face. In particular, they extend from the closing surface in the direction of the holding structure and are in particular arranged only above the holding structure.

Insbesondere weist wenigstens eine Seitenwange, speziell beide Seitenwangen jeweils eine der Abschlussfläche gegenüberliegende Abstützfläche auf. Die Abstützflächen sind insbesondere parallel zur Abschlussfläche ausgerichtet. Sie sind insbesondere im Vergleich zur Abschlussfläche als schmale Streifen ausgeführt.In particular, at least one side cheek, specifically both side cheeks, each have a support surface opposite the closing surface. The support surfaces are in particular aligned parallel to the end surface. They are designed as narrow strips, especially compared to the end surface.

Die Abstützfläche, die Abschlussfläche und die Seitenwangen mit den Abstützflächen sind insbesondere so angeordnet, dass ein den Messbandvorrat aufnehmender Behälter, insbesondere eine Kartonbox passgenau aufgenommen werden kann, also sehr sicher gehalten werden kann.The support surface, the end surface and the side walls with the support surfaces are in particular arranged in such a way that a container accommodating the supply of measuring tape, in particular a cardboard box, can be accommodated with a precise fit, ie can be held very securely.

In Ausgestaltung der Erfindung weist wenigstens eine Seitenwange, insbesondere beide Seitenwangen der Aufnahmevorrichtung eine Lasche auf, über welche die Aufnahmevorrichtung an der Haltestruktur fixierbar ist. Damit ist eine besonders einfache und damit kostengünstige Verbindung zwischen der Aufnahmevorrichtung und der Haltestruktur möglich. Die Lasche verfügt insbesondere über ein Durchgangsloch, über das die Lasche und damit die Aufnahmevorrichtung an die Haltestruktur angeschraubt werden kann.In an embodiment of the invention, at least one side cheek, in particular both side cheeks, of the receiving device has a tab, via which the receiving device can be fixed to the holding structure. This is a particularly simple and therefore inexpensive connection between the recording device and the Holding structure possible. In particular, the lug has a through hole, via which the lug and thus the receiving device can be screwed to the holding structure.

In Ausgestaltung der Erfindung ist die Aufnahmevorrichtung einstückig ausgeführt. Damit ist sie besonders kostengünstig herstellbar. Die Aufnahmevorrichtung ist insbesondere aus einem Metallblech hergestellt, aus dem eine entsprechende Kontur ausgestanzt wird, welche anschliessend durch Biegen bzw. Abkanten in die gewünschte Form gebracht wird.In an embodiment of the invention, the receiving device is designed in one piece. This makes it particularly inexpensive to produce. The receiving device is made in particular from a metal sheet, from which a corresponding contour is punched out, which is then brought into the desired shape by bending or edging.

In Ausgestaltung der Erfindung ist die Befestigungsvorrichtung so ausgeführt und angeordnet, dass das Messband eingeklemmt und damit gehalten wird. Damit wird eine einfache und kostengünstige Befestigung des Messbands an der Haltestruktur ermöglicht, welche ausserdem wieder einfach zu lösen ist und keine Beschädigungen am zur Befestigung genutzten Stück Messband bewirkt. Beschädigungen am zur Befestigung genutzten Stück Messband müssen insbesondere verhindert werden, da dieses Stück Messband bei der Verlängerung des Verfahrwegs ebenfalls im Verlängerungsstück angeordnet ist und dessen Ortsinformationen zur Ermittlung der aktuellen Position der Aufzugkabine genutzt werden.In an embodiment of the invention, the fastening device is designed and arranged in such a way that the measuring tape is clamped and thus held. This enables the measuring tape to be attached to the holding structure in a simple and cost-effective manner, which is also easy to detach again and does not cause any damage to the piece of measuring tape used for attachment. Damage to the piece of measuring tape used for attachment must be prevented in particular, since this piece of measuring tape is also arranged in the extension piece when the travel path is extended and its location information is used to determine the current position of the elevator car.

In Ausgestaltung der Erfindung weist die Befestigungsvorrichtung eine Klemmplatte auf, welche an der Haltestruktur so fixierbar ist, dass das Messband zwischen Klemmplatte und Haltestruktur eingeklemmt ist. Dies ermöglicht besonders effektiv, eine Befestigung des Messbands an der Haltestruktur ohne Beschädigungen des Messbands.In an embodiment of the invention, the fastening device has a clamping plate which can be fixed to the holding structure in such a way that the measuring tape is clamped between the clamping plate and the holding structure. This enables the measuring tape to be attached to the holding structure in a particularly effective manner without damaging the measuring tape.

Die Klemmplatte wird insbesondere direkt oder indirekt an die Haltestruktur geschraubt und das Messband zwischen Klemmplatte und Haltestruktur festgeklemmt. Das Messband kann insbesondere auch zwischen der Klemmplatte und einer zwischen Klemmplatte und Haltestruktur angeordnete Zwischenplatte festgeklemmt werden. In diesem Fall wird das Messband nur mittelbar zwischen Klemmplatte und Haltestruktur festgeklemmt. Die Zwischenplatte ist insbesondere ebenfalls an die Haltestruktur angeschraubt. Die Klemmplatte und/oder die Zwischenplatte weisen insbesondere einen Gummiüberzug auf. Damit werden Beschädigungen des Messbands durch das Einklemmen besonders wirkungsvoll verhindert.In particular, the clamping plate is screwed directly or indirectly to the holding structure and the measuring tape is clamped between the clamping plate and the holding structure. In particular, the measuring tape can also be clamped between the clamping plate and an intermediate plate arranged between the clamping plate and the holding structure. In this case, the measuring tape is clamped only indirectly between the clamping plate and the holding structure. In particular, the intermediate plate is likewise screwed to the holding structure. In particular, the clamping plate and/or the intermediate plate have a rubber coating. This is particularly effective in preventing damage to the measuring tape caused by pinching.

In Ausgestaltung der Erfindung weist die Klemmplatte an ihrer oberen und/oder unteren Kante eine von der Haltestruktur weg weisende Abkantung auf. Damit werden Beschädigungen des Messbands durch die Klemmplatte auch bei einem Schwingen des Messbands wirkungsvoll verhindert. Die Abkantungen weisen beispielsweise einen Winkel gegenüber einem Bereich der Klemmplatte, an der das Messband anliegt, zwischen 45 und 80° auf.In an embodiment of the invention, the clamping plate has a bevel pointing away from the holding structure on its upper and/or lower edge. This effectively prevents the measuring tape from being damaged by the clamping plate, even if the measuring tape vibrates. The folds have, for example, an angle of between 45 and 80° with respect to a region of the clamping plate on which the measuring tape rests.

In Ausgestaltung der Erfindung ist die Haltestruktur dazu vorgesehen, an einer Führungsschiene der Aufzuganlage fixiert zu werden. Dies ermöglicht eine besonders einfache Fixierung der Haltestruktur, insbesondere ohne dass ein Bohren von Löchern in eine Schachtwand des Aufzugschachts notwendig ist. Die Haltestruktur kann beispielsweise mittels geeigneter Klemmelemente an der Führungsschiene fixiert werden.In an embodiment of the invention, the holding structure is intended to be fixed to a guide rail of the elevator installation. This enables the holding structure to be fixed in a particularly simple manner, in particular without it being necessary to drill holes in a shaft wall of the elevator shaft. The holding structure can be fixed to the guide rail, for example, by means of suitable clamping elements.

Bei dieser Ausgestaltung ist die Aufnahmevorrichtung insbesondere zwischen der Haltestruktur und einer Schachtwand angeordnet, an welcher die genannte Führungsschiene zumindest mittelbar fixiert ist.In this configuration, the receiving device is arranged in particular between the holding structure and a shaft wall, to which the mentioned guide rail is fixed at least indirectly.

Die beschriebenen Messbandanordnungen lassen sich besonders vorteilhaft in einem Positionsbestimmungssystem für einen Einsatz in einer Aufzuganlage zum Bestimmen einer Position einer Aufzugkabine entlang eines Verfahrwegs einsetzen. Ein derartiges Positionsbestimmungssystem ist besonders vorteilhaft in einer Aufzuganlage einsetzbar.The measuring tape arrangements described can be used particularly advantageously in a position determination system for use in an elevator system for determining a position of an elevator car along a travel path. Such a position determination system can be used particularly advantageously in an elevator installation.

Die oben genannte Aufgabe wird auch durch ein Verfahren zum Installieren und Betreiben einer Aufzuganlage in einem Aufzugschacht eines sich in seiner Bauphase befindenden Gebäudes gelöst, das wenigstens die folgenden Schritte aufweist:

  • Einbringen einer oben beschriebenen Messbandanordnung in den Aufzugschacht, wobei
    • die Haltestruktur der Messbandanordnung an einem oberen Ende eines unteren Verfahrwegstücks,
    • das Messband mittels der Befestigungsvorrichtung an der Haltestruktur befestigt und
    • ein Messbandvorrat in der Aufnahmevorrichtung angeordnet wird;
  • Verlängern des Verfahrwegs um ein Verlängerungsstück nach oben, wobei
    • das Messband von der Haltestruktur gelöst,
    • ein Messbandstück des Messbandvorrats entlang des Verlängerungsstücks angeordnet,
    • die Haltestruktur der Messbandanordnung an einem oberen Ende des Verlängerungsstücks angeordnet und
    • das Messband mittels der Befestigungsvorrichtung an der Haltestruktur befestigt
      wird.
The above object is also achieved by a method for installing and operating an elevator system in an elevator shaft of a building that is in the construction phase, which has at least the following steps:
  • Introduction of a measuring tape arrangement described above in the elevator shaft, wherein
    • the support structure of the measuring tape assembly at an upper end of a lower length of travel,
    • the measuring tape is fastened to the holding structure by means of the fastening device and
    • placing a supply of measuring tape in the receiving device;
  • Extending the traverse path by an extension piece upwards, where
    • the measuring tape is detached from the support structure,
    • a measuring tape piece of the measuring tape supply arranged along the extension piece,
    • the support structure of the measuring tape assembly is arranged at an upper end of the extension piece and
    • the measuring tape is fastened to the holding structure by means of the fastening device
      becomes.

Nach der Verlängerung des Verfahrwegs bildet das Verlängerungsstück ein oberes Verfahrwegstück.After the lengthening of the travel path, the extension piece forms an upper travel path piece.

Die genannten Schritte werden insbesondere in der angegebenen Reihenfolge ausgeführt, können aber auch in einer anderen Reihenfolge ausgeführt werden. Neben den genannten Schritten werden insbesondere weitere Schritte, wie beispielsweise ein Fixieren von Führungsschienen im Aufzugschacht ausgeführt.In particular, the steps mentioned are carried out in the order given, but can also be carried out in a different order. In addition to the steps mentioned, further steps, such as fixing guide rails in the elevator shaft, are carried out.

Vor der Verlängerung des Verfahrwegs wird insbesondere eine Aufzugkabine der Aufzuganlage entlang des unteren Verfahrwegstücks verlagert, wobei die Position der Aufzugkabine mit Hilfe der genannten Messbandanordnung bestimmt wird.Before the travel path is extended, in particular an elevator car of the lift system is moved along the lower travel path section, with the position of the elevator car being determined with the aid of the measuring tape arrangement mentioned.

Nach der Verlängerung des Verfahrwegs wird insbesondere die Aufzugkabine der Aufzuganlage entlang des unteren Verfahrwegstücks und des Verlängerungsstücks verlagert, wobei die Position der Aufzugkabine mit Hilfe der genannten Messbandanordnung bestimmt wird.After the lengthening of the travel path, in particular the elevator car of the elevator system is displaced along the lower travel path piece and the extension piece, with the position of the elevator car being determined with the aid of the measuring tape arrangement mentioned.

Wenn das Messband mittels der Befestigungsvorrichtung durch Verklemmen an der Haltestruktur befestigt wird, dann wird zum Lösen des Messbands von der Haltestruktur lediglich die Verklemmung aufgehoben und die Befestigungsvorrichtung entlang des Messbands nach oben geschoben, ohne das Messband aus der Befestigungsvorrichtung zu entfernen. Damit kann wirkungsvoll verhindert werden, dass sich das Messband bei der Verlängerung des Verfahrwegs verdreht. Unter einem Lösen des Messbands von der Haltestruktur wird demnach verstanden, dass die Haltestruktur nach dem Lösen gegenüber dem Messband verlagert werden kann.If the measuring tape is attached to the holding structure by means of the fastening device by clamping, then to release the measuring tape from the holding structure, the clamping is simply canceled and the fastening device is pushed up along the measuring tape without removing the measuring tape from the fastening device. This effectively prevents the measuring tape from twisting when the travel path is lengthened. Detaching the measuring tape from the holding structure is therefore understood to mean that the holding structure after detaching can be shifted relative to the measuring tape.

Die Verlängerung des Verfahrwegs kann wiederholt werden. Sie wird insbesondere so lange wiederholt, bis sich der Verfahrweg über den gesamten Aufzugschacht des fertiggestellten Gebäudes erstreckt. Bei der letzten Verlängerung kann die beschriebene Haltestruktur durch eine Haltestruktur ersetzt werden, die für Aufzuganlagen vorgesehen ist, deren Verfahrweg sich nach der Installation und der ersten Inbetriebnahme nicht mehr ändert, also beispielsweise durch eine Haltevorrichtung gemäss der internationalen Patentanmeldung der Anmelderin mit der Anmeldenummer PCT/EP2019/05 1045 .The lengthening of the travel distance can be repeated. In particular, it is repeated until the travel path extends over the entire elevator shaft of the completed building. In the last extension, the support structure described can be replaced by a support structure that is provided for elevator systems whose travel no longer changes after installation and initial operation, i.e., for example, by a support device according to the applicant's international patent application with the application number PCT/EP2019/05 1045 .

Beim Einsatz der erfindungsgemässen Messbandanordnung und beim Ausführen des erfindungsgemässen Verfahrens wird das Messband von unten nach oben installiert. Es wird also ein Ende des Messbands am unteren Ende des Verfahrwegs und damit des Aufzugschachts angeordnet und dann das Messband nach oben geführt. Ein Messbandvorrat befindet sich damit wie beschrieben bei der Haltestruktur am oberen Ende des Verfahrwegs. Bei einer Erstinbetriebnahme der Aufzuganlage wird üblicherweise eine so genannte Lernfahrt durchgeführt. Dazu wird die Aufzugkabine langsam an alle zu bedienenden Stockwerke verfahren und die Position der Kabine an den Stockwerken erfasst und gespeichert. Nach dem Speichern der genannten Positionen kann die Aufzugkabine die Stockwerke automatisch anfahren. Die beschriebene Installation des Messbands von unten nach oben hat den Vorteil, dass eine in einem Verfahrwegstück durchgeführte Lernfahrt nach einer Verlängerung des Verfahrwegs nicht wiederholt werden muss, da in diesem Verfahrwegstück die Zuordnung zwischen den Ortsinformationen des Messbands und der Position der Aufzugkabine unverändert bleibt. Dies wäre nicht so, wenn der Messbandvorrat am unteren Ende des Aufzugschachts bleiben würde und ein am oberen Ende des Verfahrwegs angeordnetes Ende des Messbands bei einer Verlängerung des Verfahrwegs nach oben verlagert werden würde.When using the measuring tape arrangement according to the invention and when carrying out the method according to the invention, the measuring tape is installed from bottom to top. One end of the measuring tape is thus arranged at the lower end of the travel path and thus of the elevator shaft, and the measuring tape is then guided upwards. A supply of measuring tape is thus located at the support structure at the upper end of the travel path, as described. When the elevator system is put into operation for the first time, a so-called learning run is usually carried out. For this purpose, the elevator car is slowly moved to all floors to be served and the position of the car on the floors is recorded and stored. After saving the positions mentioned, the elevator car can move to the floors automatically. The described installation of the measuring tape from bottom to top has the advantage that a learning run carried out in a travel section does not have to be repeated after the travel path has been extended, since the assignment between the location information of the measuring tape and the position of the elevator car remains unchanged in this travel section. This would not be the case if the supply of measuring tape remained at the bottom of the hoistway and an end of the measuring tape located at the top of the travel was displaced upwardly as the travel lengthened.

Es wird darauf hingewiesen, dass einige der möglichen Merkmale und Vorteile der Erfindung hierin mit Bezug auf unterschiedliche Ausführungsformen der erfindungsgemässen Messbandanordnung einerseits und des erfindungsgemässen Verfahren andererseits beschrieben sind. Ein Fachmann erkennt, dass die Merkmale in geeigneter Weise kombiniert, angepasst, übertragen oder ausgetauscht werden können, um zu weiteren Ausführungsformen der Erfindung zu gelangen.It is pointed out that some of the possible features and advantages of the invention are described herein with reference to different embodiments of the measuring tape arrangement according to the invention on the one hand and the method according to the invention on the other hand. A person skilled in the art recognizes that the features can be combined, adapted, transferred or interchanged in a suitable manner in order to arrive at further embodiments of the invention.

Gemäss Fig. 1 verfügt eine Aufzuganlage 10 über eine Aufzugkabine 12, die innerhalb eines Aufzugschachts 14 vertikal entlang eines Verfahrwegs 16 verlagert werden kann. Die Aufzugkabine 12 sowie ein Gegengewicht 20 sind hierzu über eine Riemenanordnung 22 miteinander verbunden, wobei die Riemenanordnung 22 über eine von einer Antriebsmaschine 24 angetriebene Treibscheibe 26 und eine Umlenkscheibe 28 geführt ist. Ein Betrieb der Antriebsmaschine 24 wird von einer Steuerung 30 gesteuert. Die Antriebsmaschine 24, die angetriebene Treibscheibe 26, die Umlenkscheibe 28 und die Steuerung 30 sind dabei auf einer Halteplattform 25 angeordnet. Während ihrer Bewegung entlang des Verfahrwegs 16 wird die Aufzugkabine 12 von Führungsschuhen 32, welche sich entlang vertikal verlaufender Führungsschienen 34 bewegen, geführt. Der Aufzugschacht 14 ist in einem Gebäude 18 angeordnet, das sich noch in seiner Bauphase befindet. Oberhalb des dargestellten Ausschnitts des Gebäudes 18 wird also noch gebaut.According to 1 an elevator system 10 has an elevator car 12 which can be displaced vertically along a travel path 16 within an elevator shaft 14 . For this purpose, the elevator car 12 and a counterweight 20 are connected to one another via a belt arrangement 22 , the belt arrangement 22 being guided over a drive pulley 26 driven by a drive machine 24 and a deflection pulley 28 . An operation of the prime mover 24 is controlled by a controller 30 . The drive machine 24, the driven traction sheave 26, the deflection sheave 28 and the controller 30 are arranged on a holding platform 25. During its movement along the travel path 16, the elevator car 12 is guided by guide shoes 32, which move along guide rails 34 running vertically. The elevator shaft 14 is located in a building 18 which is still under construction. There is still construction going on above the section of building 18 shown.

Um eine genaue Position der Aufzugkabine 12 entlang von deren Verfahrweg 16 bestimmen zu können, ist in dem Aufzugschacht 14 ein Messband 36 beispielsweise in Form eines Magnetbandes angebracht. Das Messband 36 erstreckt sich im Wesentlichen entlang des gesamten von der Aufzugkabine 12 zu durchlaufenden Verfahrwegs 16 und vorzugsweise parallel zu diesem. Beispielsweise kann das Messband 36 an bzw. parallel zu einer der Führungsschienen 34 verlaufen.In order to be able to determine an exact position of the elevator car 12 along its travel path 16, a measuring tape 36, for example in the form of a magnetic tape, is attached in the elevator shaft 14. The measuring tape 36 extends essentially along the entire travel path 16 to be traversed by the elevator car 12 and preferably parallel to it. For example, the measuring tape 36 at or parallel run to one of the guide rails 34.

An der Aufzugkabine 12 ist eine Auslesevorrichtung 38 vorgesehen, mithilfe derer in dem Messband 36 gespeicherte variierende Ortsinformationen ausgelesen werden können. Für den Fall, dass das Messband 36 als Magnetband ausgebildet ist, sind die variierenden Ortsinformationen als lokal variierende Magnetisierungen in magnetisierbarem Material des Magnetbandes gespeichert. Diese lokalen Magnetisierungen können mithilfe eines Magnetlesekopfs 40 der Auslesevorrichtung 38 sowie einer hierfür geeignet ausgebildeten Auslesesensorik 42 ausgelesen werden.A reading device 38 is provided on the elevator car 12, with the aid of which varying location information stored in the measuring tape 36 can be read out. If the measuring tape 36 is designed as a magnetic tape, the varying location information is stored as locally varying magnetizations in magnetizable material of the magnetic tape. These local magnetizations can be read using a magnetic read head 40 of the read-out device 38 and a read-out sensor system 42 suitably designed for this purpose.

Während sich die Aufzugkabine 12 durch den Aufzugschacht 14 bewegt, wird die Auslesevorrichtung 38, welche durch einen Befestigungsblock 44 beispielsweise an einem Dach der Aufzugkabine 12 befestigt ist, geführt von Führungsrollen 46 entlang des Messbandes 36 verlagert. Die dabei von der Auslesevorrichtung 38 ausgelesenen Ortsinformationen können an eine Auswertevorrichtung 48 weitergeleitet werden, wo sie ausgewertet oder zumindest vorverarbeitet werden, um dann über eine Kabelverbindung 50, oder alternativ drahtlos, an die Steuerung 30 der Aufzuganlage 10 übermittelt werden zu können.As the elevator car 12 moves through the elevator shaft 14, the readout device 38, which is attached by a mounting block 44 to a roof of the elevator car 12, for example, is displaced along the measuring tape 36, guided by guide rollers 46. The location information read out by the read-out device 38 can be forwarded to an evaluation device 48, where it is evaluated or at least pre-processed in order to then be able to be transmitted to the controller 30 of the elevator system 10 via a cable connection 50, or alternatively wirelessly.

Basierend auf einer demgemäss ermittelten Absolutposition der Aufzugkabine 12 kann die Steuerung 30 dann die Antriebsmaschine 24 geeignet ansteuern, um die Aufzugkabine 12 präzise an eine gewünschte Position verlagern zu können.Based on an absolute position of the elevator car 12 determined in this way, the controller 30 can then suitably control the drive machine 24 in order to be able to move the elevator car 12 precisely to a desired position.

Um das Messband 36 innerhalb des Aufzugschachts 14 geeignet fixieren zu können, ist das Messband 36 über eine in Fig. 1 nicht dargestellte Befestigungsvorrichtung (66 in Fig. 2 bis 4) an einer Haltestruktur 52 befestigt. Die Haltestruktur 52 ist an einem oberen Ende 53 des Verfahrwegs 16 an der Führungsschiene 34 fixiert und damit innerhalb des Aufzugschachts 14 stationär bzw. ortsfest angeordnet. An der Haltestruktur 52 ist auch ein in Fig. 1 nicht dargestellter Messbandvorrat (80 in Fig. 2) angeordnet. Der Messbandvorrat umfasst zumindest ein Messbandstück (82 in Fig. 2), das für eine Verlängerung des Verfahrwegs 16 genutzt wird. Ein unteres Ende des Messbandes 36 kann in einem unteren Bereich des Aufzugschachts 14, beispielsweise am Boden des Aufzugschachts 14, befestigt sein oder mit einem nicht dargestellten Spanngewicht versehen sein.In order to be able to fix the measuring tape 36 suitably within the elevator shaft 14, the measuring tape 36 is connected via an in 1 non-illustrated fastener (66 in Figures 2 to 4 ) attached to a support structure 52. The holding structure 52 is fixed to the guide rail 34 at an upper end 53 of the travel path 16 and is therefore arranged in a stationary or stationary manner within the elevator shaft 14 . Also on the support structure 52 is an in 1 measuring tape supply not shown (80 in 2 ) arranged. The measuring tape supply includes at least one piece of measuring tape (82 in 2 ), which is used to extend the travel path 16. A lower end of the measuring tape 36 can be fastened in a lower area of the elevator shaft 14, for example on the floor of the elevator shaft 14, or it can be provided with a tension weight, not shown.

Die Aufzuganlage 10 wird zunächst nur in einem untersten Abschnitt 54 des Aufzugschachts 14 installiert und betrieben. Die Aufzugkabine 12 wird damit entlang des Verfahrwegs 16, welcher auch als ein unteres Verfahrwegstück bezeichnet werden kann, verlagert. Die Position der Aufzugkabine 12 wird dabei auf Basis der Ortsinformationen des Messbands 36 bestimmt.The elevator system 10 is initially only installed and operated in a lowermost section 54 of the elevator shaft 14 . The elevator car 12 is thus displaced along the travel path 16, which can also be referred to as a lower travel path piece. The position of the elevator car 12 is determined on the basis of the location information from the measuring tape 36 .

Oberhalb des untersten Abschnitts 54 des Aufzugschachts 14 wird am Gebäude 18 und damit auch am Aufzugschacht 14 noch gebaut. Zum Schutz des untersten Abschnitts des Aufzugschachts kann im Aufzugschacht eine so genannte, nicht dargestellte Schutzplattform angeordnet sein, die den untersten Abschnitt des Aufzugschachts vor herabfallenden Gegenständen schützt.Above the lowest section 54 of the elevator shaft 14, the building 18 and thus also the elevator shaft 14 are still under construction. To protect the lowest section of the elevator shaft, a so-called protective platform (not shown) can be arranged in the elevator shaft, which protects the lowest section of the elevator shaft from falling objects.

Sobald ein weiterer Abschnitt des Gebäudes 18 und damit ein oberhalb des untersten Abschnitts 54 angeordneter zweiter Abschnitt 56 des Aufzugschachts 14 fertiggestellt ist, wird die Aufzuganlage 10 auch im zweiten Abschnitt 56 des Aufzugschachts 14 installiert. Dazu wird zunächst die Halteplattform 25 mit Antriebsmaschine 24, angetriebene Treibscheibe 26, Umlenkscheibe 28 und die Steuerung 30 mittels eines nicht dargestellten Baukrans nach oben verlagert und im Aufzugschacht 14 fixiert. Dann werden alle notwendigen Bauteile der Aufzuganlage 10, beispielsweise Führungsschienen 34, auch im zweiten Abschnitt 56 des Aufzugschachts 14 montiert. Der Verfahrweg 16 der Aufzugkabine 12 wird damit um ein Verlängerungsstück 58 nach oben verlängert. Um die Position der Aufzugkabine 12 auch entlang des Verlängerungsstücks 58 bestimmen zu können, wird das Messband 36 auch entlang des Verlängerungsstücks 58 angeordnet. Dazu wird zunächst das Messband 36 von der Haltestruktur 52 gelöst und anschliessend ein Messbandstück (82 in Fig. 2) des Messbandvorrats (80 in Fig. 2) entlang des Verlängerungsstücks 58 angeordnet. Abschliessend wird die Haltestruktur 52 an einem oberen Ende 60 des Verlängerungsstücks 58 angeordnet und das Messband 36 mittels der Befestigungsvorrichtung (66 in Fig. 2 und 3) an der Haltestruktur 52 befestigt.As soon as a further section of the building 18 and thus a second section 56 of the elevator shaft 14 arranged above the lowest section 54 is completed, the elevator system 10 is also installed in the second section 56 of the elevator shaft 14 . For this purpose, the holding platform 25 with the drive machine 24, the driven traction sheave 26, the deflection sheave 28 and the controller 30 are first moved upwards by means of a construction crane (not shown) and fixed in the elevator shaft 14. Then all the necessary components of the elevator installation 10, for example guide rails 34, are also installed in the second section 56 of the elevator shaft 14. The travel path 16 of the elevator car 12 is thus lengthened upwards by an extension piece 58 . In order to be able to determine the position of the elevator car 12 along the extension piece 58 as well, the measuring tape 36 is also arranged along the extension piece 58 . For this purpose, the measuring tape 36 is first detached from the holding structure 52 and then a measuring tape piece (82 in 2 ) of measuring tape supply (80 in 2 ) arranged along the extension piece 58. Finally, the holding structure 52 is arranged at an upper end 60 of the extension piece 58 and the measuring tape 36 is fastened by means of the fastening device (66 in 2 and 3 ) attached to the support structure 52.

Wenn alle notwendigen Installationen im zweiten Abschnitt 56 des Aufzugschachts 14 abgeschlossen sind, kann die Aufzuganlage 10 auch im zweiten Abschnitt 56 in Betrieb genommen werden. Damit kann die Aufzugkabine 12 entlang des unteren Verfahrwegstücks 16 und des Verlängerungsstücks 58 verlagert werden. Die Position der Aufzugkabine 12 wird dabei ebenfalls auf Basis der Ortsinformationen des Messbands 36 bestimmt.When all necessary installations in the second section 56 of the elevator shaft 14 have been completed, the elevator system 10 can also be put into operation in the second section 56 . The elevator car 12 can thus be displaced along the lower travel path piece 16 and the extension piece 58 . The position of In this case, the elevator car 12 is likewise determined on the basis of the location information from the measuring tape 36 .

Diese beschriebene Verlängerung des Verfahrwegs wird so lange wiederholt, bis das Gebäude fertiggestellt ist, der Aufzugschacht 14 damit seine endgültige Höhe erreicht hat.This described extension of the travel path is repeated until the building is completed, and the elevator shaft 14 has thus reached its final height.

In den Fig. 2 und 3 ist die Haltestruktur 52 mit allen an ihr angeordneten Teilen dargestellt. Die Haltestruktur 52 ist als eine längliche Schiene ausgeführt, die mittels einer Klemmvorrichtung 62 an einer Führungsschiene 34 fixiert ist. Die Haltestruktur 52 ist so angeordnet, dass sie an einem Schienenfuss 64 der Führungsschiene 34 anliegt, also zwischen der Führungsschiene 34 und einer Schachtwand des Aufzugschachts 14, an der die Führungsschiene 34 fixiert ist, angeordnet ist. An einem der Führungsschiene 34 gegenüberliegenden Ende der Haltestruktur 52 ist eine in Fig. 4 vergrössert dargestellte Befestigungsvorrichtung 66 angeordnet, mittels welcher das Messband 36 an der Haltestruktur 52 befestigt werden kann. Die Befestigungsvorrichtung 66 besteht aus einer mittels zweier Schrauben-Mutter-Verbindungen 70 an der Haltestruktur 52 fixierte Zwischenplatte 68 und eine mittels vier weiterer Schrauben-Mutter-Verbindungen 72 an der Haltestruktur 52 fixierte Klemmplatte 74. Zwischen der Zwischenplatte 68 und der Klemmplatte 74 verläuft das Messband 36, welches damit zwischen der Klemmplatte 74 und der Zwischenplatte 68 festgeklemmt ist. Da die Zwischenplatte 68 an der Haltestruktur 52 fixiert ist, ist das Messband 36 damit zumindest mittelbar zwischen der Klemmplatte 74 und der Haltestruktur 52 festgeklemmt. Die Klemmplatte 74 weist an ihrer oberen und unteren Kante jeweils eine von der Haltestruktur 52 weg weisende Abkantung 76 auf. Die Zwischenplatte 68 und die Klemmplatte 74 können zumindest auf ihrer zum Messband 36 ausgerichteten Seite mit einem Gummiüberzug versehen sein.In the 2 and 3 the holding structure 52 is shown with all parts arranged on it. The holding structure 52 is designed as an elongate rail which is fixed to a guide rail 34 by means of a clamping device 62 . The holding structure 52 is arranged in such a way that it bears against a rail foot 64 of the guide rail 34, ie is arranged between the guide rail 34 and a shaft wall of the elevator shaft 14, to which the guide rail 34 is fixed. At one end of the holding structure 52 opposite the guide rail 34 is an in 4 fastening device 66 shown enlarged, by means of which the measuring tape 36 can be fastened to the holding structure 52 . The fastening device 66 consists of an intermediate plate 68 fixed to the holding structure 52 by means of two screw-nut connections 70 and a clamping plate 74 fixed to the holding structure 52 by means of four further screw-nut connections 72. Between the intermediate plate 68 and the clamping plate 74 runs the Measuring tape 36, which is thus clamped between the clamping plate 74 and the intermediate plate 68. Since the intermediate plate 68 is fixed to the holding structure 52 , the measuring tape 36 is thus clamped at least indirectly between the clamping plate 74 and the holding structure 52 . The clamping plate 74 has a bevel 76 pointing away from the holding structure 52 on its upper and lower edge. The intermediate plate 68 and the clamping plate 74 can be provided with a rubber coating at least on their side aligned with the measuring tape 36 .

An der Haltestruktur 52 ist ausserdem eine Aufnahmevorrichtung 78 zum Aufnehmen eines symbolisch als ein Kreis dargestellten Messbandvorrats 80 angeordnet. Der Messbandvorrat 80 umfasst ein Messbandstück 82, das bei einer Verlängerung des Verfahrwegs 16 entlang des Verlängerungsstücks 58 angeordnet wird. Die Aufnahmevorrichtung 78 ist einstückig ausgeführt. Sie verfügt über eine horizontal verlaufende Auflagefläche 84, die unterhalb der Haltestruktur 52 angeordnet ist. Damit kann sich der Messbandvorrat 80 nach unten an der Auflagefläche 84 und horizontal in Richtung Führungsschiene 34 an der Haltestruktur 52 abstützen.Also arranged on the holding structure 52 is a receiving device 78 for receiving a supply of measuring tape 80 symbolically represented as a circle. The supply of measuring tape 80 comprises a piece of measuring tape 82 which is arranged along the extension piece 58 when the travel path 16 is extended. The receiving device 78 is designed in one piece. It has a horizontally running bearing surface 84 which is arranged underneath the holding structure 52 . The supply of measuring tape 80 can thus be supported downwards on the support surface 84 and horizontally in the direction of the guide rail 34 on the holding structure 52 .

Die Aufnahmevorrichtung 78 weist ausserdem eine Abschlussfläche 86 auf, die in einem rechten Winkel zur Auflagefläche 84 verläuft und hauptsächlich parallel und mit einem gewissen Abstand zur Haltestruktur 52 angeordnet ist. Sie überragt dabei die Haltstruktur 52 nach oben. Eine maximale Erstreckung der Abschlussfläche 86 entlang der Haltestruktur 52 im Bereich der Auflagefläche 84 ist dabei geringer als eine maximale Erstreckung der Abschlussfläche 86 oberhalb der Haltestruktur 52. Der sich auf der Auflagefläche 84 abstützende Messbandvorrat 80 ist damit teilweise zwischen der Haltestruktur 52 und der Abschlussfläche 86 angeordnet.The receiving device 78 also has an end surface 86 which runs at a right angle to the bearing surface 84 and is arranged mainly parallel to and at a certain distance from the holding structure 52 . It protrudes above the support structure 52 upwards. A maximum extension of the end face 86 along the holding structure 52 in the region of the bearing surface 84 is smaller than a maximum extension of the end face 86 above the holding structure 52. The supply of measuring tape 80 supported on the bearing surface 84 is thus partially between the holding structure 52 and the end face 86 arranged.

Die Aufnahmevorrichtung 78 wird seitlich durch zwei sich gegenüberliegende, mit der Abschlussfläche 86 verbundene und im rechten Winkel dazu verlaufenden Seitenwangen 88 abgeschlossen, welche eine horizontale Verlagerung des Messbandvorrats 80 entlang der Haltestruktur 52 begrenzen. Die beiden Seitenwangen 88 weisen ausserdem jeweils eine der Abschlussfläche 86 gegenüberliegende Abstützfläche 90 auf, womit sich auch ein rechter Winkel zwischen Abstützfläche 90 und Seitenwange 88 ergibt. Die beiden Seitenwangen 88 weisen ausserdem jeweils eine Lasche 94 auf, über welche die Seitenwangen 88 und damit die Aufnahmevorrichtung 78 an der Haltestruktur 52 angeschraubt und damit fixiert ist. Die Laschen 94 verfügen dazu jeweils über ein nicht dargestelltes Durchgangsloch, durch das jeweils eine Schraube zum Anschrauben an der Haltestruktur 52 gesteckt werden kann.The receiving device 78 is closed off laterally by two opposite side walls 88 which are connected to the closing surface 86 and run at right angles thereto and which limit horizontal displacement of the supply of measuring tape 80 along the holding structure 52 . The two side walls 88 also each have a support surface 90 opposite the closing surface 86 , which also results in a right angle between the support surface 90 and the side wall 88 . The two side walls 88 also each have a lug 94, via which the side walls 88 and thus the receiving device 78 are screwed to the holding structure 52 and thus fixed. For this purpose, the lugs 94 each have a through hole (not shown) through which a screw can be inserted for screwing onto the holding structure 52 .

Die Abstützfläche 84, die Abschlussfläche 86 und die Seitenwangen 88 mit den Abstützflächen 90 sind so angeordnet, dass ein den Messbandvorrat 80 aufnehmender Behälter, insbesondere eine Kartonbox 92 passgenau aufgenommen werden kann.The support surface 84, the end surface 86 and the side walls 88 with the support surfaces 90 are arranged in such a way that a container holding the supply of measuring tape 80, in particular a cardboard box 92, can be accommodated with a precise fit.

Das Messband 36, die Haltestruktur 52, die Befestigungsvorrichtung 66 und die Aufnahmevorrichtung 78 bilden zusammen eine Messbandanordnung 96. Die Messbandanordnung 96, die Auslesevorrichtung 38 und die Auswertevorrichtung 48 bilden zusammen ein Positionsbestimmungssystem 98 (siehe Fig. 1).The measuring tape 36, the holding structure 52, the fastening device 66 and the receiving device 78 together form a measuring tape arrangement 96. The measuring tape arrangement 96, the readout device 38 and the evaluation device 48 together form a position determination system 98 (see 1 ).
