Description

Die Erfindung betrifft ein Wartungsverfahren für einen Aufzug, insbesondere bei der Wartung von Aufzügen in hohen Gebäuden.The invention relates to a maintenance method for an elevator, in particular in the maintenance of elevators in tall buildings.

Unter einem Gebäude mit hoher Bauhöhe ist ein Gebäude ab ca. 30 Stockwerken und höher zu verstehen. Gerade bei solch hohen Gebäuden ist die Installation eines Aufzugs relativ aufwändig. Für die Installation werden oft spezielle Verfahren und Hilfsmittel bereitgestellt, damit die Installation zeitlich effizient durchführbar ist.A building with a high height is to be understood as a building from approx. 30 storeys upwards. Especially with such high buildings, the installation of a lift is relatively expensive. Often, special procedures and tools are provided for the installation to make the installation efficient in terms of time.

Die US 2010/133048 A1 beschreibt ein Verfahren zur Installation eines Aufzugs, bei dem ein Teil der später im normalen Betrieb des Aufzugs genutzte Aufzugskabine als eine Installationsplattform genutzt wird.The US 2010/133048 A1 describes a method for installing an elevator in which a part of the elevator car used later in the normal operation of the elevator is used as an installation platform.

Die JP S64 2986 A ein Verfahren zur Installation eines Aufzugs, bei dem eine Installationseinrichtung mit zwei übereinander angeordneten Serviceplattformen verwendet wirdThe JP S64 2986 A a method for installing a lift, in which an installation device is used with two superposed service platforms

US2010/0133048 A1 zeigt beispielsweise ein Installationsverfahren für einen Aufzug in einem hohen Gebäude, in dem eine verfahrbare Installationsplattform genutzt wird. Beim Start des Installationsverfahrens ist die Installationsplattform im Bereich der Schachtgrube positioniert. Fortlaufend werden Aufzugskomponenten auf die Installationsplattform gebracht, von wo aus diese im Schachtbereich montiert werden. Dabei sieht das Installationsverfahren vor, dass die Installationsplattform ansteigend in unterschiedliche Montagepositionen mittels eines Hebezeugs verfahren wird, bis die Installationsplattform eine oberste bzw. letzte Montageposition erreicht. Schliesslich dient die Installationsplattform selbst zumindest als Teilstruktur der Aufzugskabine. US2010 / 0133048 A1 shows, for example, an installation method for a lift in a high building in which a movable installation platform is used. When starting the installation process, the installation platform is positioned in the pit area. Elevator components are continuously brought to the installation platform, from where they are mounted in the shaft area. The installation method provides that the installation platform is increasingly moved into different mounting positions by means of a hoist until the installation platform reaches a top or last mounting position. Finally, the installation platform itself serves at least as a substructure of the elevator car.

Dieses Installationsverfahren zeichnet sich also nicht nur durch eine effiziente Vorgehensweise aus, sondern auch durch die optimale Ausnutzung der bereits während der Installation vorhandenen Strukturen, indem die Installationsplattform oder zumindest Teile davon in der späteren Aufzugskabine verbaut werden.This installation method is not only characterized by an efficient approach, but also by the optimal utilization of existing structures already during the installation, by installing the installation platform or at least parts of it in the later elevator car.

Daher kann die Aufgabe der vorliegenden Erfindung darin gesehen werden die Nutzung einer zuvor in einem Installationsverfahren genutzten Aufzugskomponente auf spätere Anwendungen im Aufzug auszudehnen, insbesondere auch auf Wartungsanwendungen.Therefore, the object of the present invention can be seen in the use of a previously in to extend an elevator component used in an installation process to subsequent applications in the elevator, in particular also to maintenance applications.

Die Aufgabe wird durch ein Wartungsverfahren mit folgendem Schritt gelöst:

  • Bereitstellen einer Serviceplattform in einem unteren Fahrbereich des Aufzugs, insbesondere einer Schachtgrube, für spätere Wartungsarbeiten, wobei die Serviceplattform zuvor zu Installationszwecken an mindestens einem Paar Kabinenführungsschienen montiert wurde und dabei als Arbeitsplattform zum Montieren von Aufzugskomponenten an eine den Fahrbereich begrenzende Struktur, insbesondere eine Schachtwand, diente,
  • Anhängen der Serviceplattform an eine Aufzugskabine und
  • Verfahren der Serviceplattform mittels eines Antriebs der Aufzugskabine in eine Wartungsposition.
The task is solved by a maintenance procedure with the following step:
  • Providing a service platform in a lower travel area of the elevator, in particular a shaft pit, for subsequent maintenance work, wherein the service platform was previously mounted for installation purposes on at least one pair of cabin guide rails and thereby as a work platform for mounting elevator components to a structure limiting the travel area, in particular a shaft wall, served,
  • Attaching the service platform to an elevator car and
  • Moving the service platform by means of a drive of the elevator car in a maintenance position.

Der Vorteil dieses Wartungsverfahrens liegt darin, dass eine zuvor benutzte Installationsplattform auch als Serviceplattform zu Wartungszwecken dienen kann. Insbesondere kann die Serviceplattform doppelt genutzt werden. Dies führt nicht nur zu einer optimierten Nutzung der Serviceplattform selber, sondern auch zu einem optimierten zeitlichen Ablauf des vorgängigen Installationsverfahrens sowie des Wartungsverfahrens selbst, da die Installationsplattform ohne aufwändige Umbauarbeiten einer neuen Anwendung zugeführt werden kann.The advantage of this maintenance procedure is that a previously used installation platform can also serve as a service platform for maintenance purposes. In particular, the service platform can be used twice. This not only leads to an optimized use of the service platform itself, but also to an optimized timing of the previous installation procedure and the maintenance process itself, since the installation platform can be fed to a new application without costly remodeling.

Speziell vorteilhaft ist es, dass die Serviceplattform bereits an Kabinenführungsschienen geführt ist. Die Serviceplattform kann hierbei in einer definierten Position im unteren Fahrbereich des Aufzugs bereitgestellt werden und stellt klare räumliche Randbedingungen für den normalen Betrieb des Aufzugs. Zudem ist die Serviceplattform für Wartungsarbeiten unterhalb der Aufzugskabine schnell verfügbar und dank der zuverlässigen Führung an den Kabinenführungsschienen sicher betreibbar.It is particularly advantageous that the service platform is already guided on cabin guide rails. The service platform can be provided here in a defined position in the lower travel range of the elevator and provides clear spatial boundary conditions for the normal operation of the elevator. In addition, the service platform for maintenance work below the elevator car is quickly available and can be safely operated thanks to the reliable guidance on the car guide rails.

Erfindungsgemäß wird die Serviceplattform an eine Aufzugskabine angehängt und sie wird durch einen Antrieb der Aufzugskabine in eine Wartungsposition verfahren, sodass auf einen bereits verfügbaren Antrieb zum Verfahren der Serviceplattform zurückgegriffen werden kann.According to the service platform is attached to an elevator car and it is moved by a drive of the elevator car in a maintenance position, so that can be used on an already available drive for moving the service platform.

Ein weiterer Schritt des Wartungsverfahrens betrifft das Anhängen der Serviceplattform an der Aufzugskabine mittels mindestens eines Verbindungselements, wobei das Verbindungelement zumindest eines folgender Elemente umfasst: eine Kette, ein Kabel, ein Seil, einen Riemen oder einen Zugstab. Mittels eines solchen Verbindungselements ist die Serviceplattform besonders einfach und zuverlässig an die Aufzugskabine koppelbar. Dabei sind sowohl an der Unterseite der Aufzugskabine als auch an der Serviceplattform Verbindungspunkte für das Verbindungselement vorzusehen, an denen beispielsweise das Verbindungselement eingehakt, eingeklemmt, eingerastet oder verschraubt werden kann.Another step of the maintenance method relates to the attachment of the service platform to the elevator car by means of at least one connecting element, wherein the connecting element comprises at least one of the following elements: a chain, a cable, a rope, a belt or a tie rod. By means of such a connecting element, the service platform is particularly simple and reliable the elevator car can be coupled. In this case, connecting points for the connecting element are to be provided both on the underside of the elevator car and on the service platform, where, for example, the connecting element can be hooked, clamped, snapped or screwed.

Vorzugsweise ist das Verbindungselement dermassen ausgelegt, dass die ServiceplattformPreferably, the connecting element is designed such that the service platform

Ein weiterer Schritt des Wartungsverfahrens betrifft das Entfernen einer Dachkonstruktion von der Serviceplattform vor dem Bereitstellen der Serviceplattform im unteren Fahrbereich und/oder das Entfernen einer Führungsverlängerung von der Serviceplattform vor dem Bereitstellen der Serviceplattform im unteren Fahrbereich. Die Dachkonstruktion bietet während der Installation Schutz vor herabfallenden Gegenständen und wird bei Wartungsarbeiten nicht mehr benötigt, insbesondere da die Aufzugskabine bereits genügend Schutz bietet. Die Führungsverlängerung leitet die Führungskräfte in einen unteren während der Installation der Kabinenführungsschienen besser verankerten Bereich der bereits montierten Kabinenführungsschienen. Auch die Führungsverlängerung wird bei Wartungsarbeiten nicht mehr benötigt. Vorteilhaft ist dabei, dass für das Bereitstellen der Serviceplattform im unteren Fahrbereich weniger Raum vorzusehen ist.Another step of the maintenance procedure involves removing a roof structure from the service platform prior to providing the service platform in the lower drive area and / or removing a guide extension from the service platform prior to providing the service platform in the lower drive area. The roof construction provides protection during installation falling objects and is no longer needed during maintenance, especially since the elevator car already provides enough protection. The guide extension guides the executives into a lower area of the already mounted cab guide rails during installation of the car guide rails. Also, the guide extension is no longer needed during maintenance. It is advantageous that less space must be provided for the provision of the service platform in the lower driving range.

Anhand von weiteren Ausführungsbeispielen und Zeichnungen wird das Wartungsverfahren weiter erläutert.On the basis of further embodiments and drawings, the maintenance method will be further explained.

Fig. 1 zeigt einen Schacht 1 eines Gebäudes mit mehreren Stockwerken 2.1, 2.2, 2.n, währen der Installation eines Aufzugs. Fig. 1 shows a shaft 1 of a building with several floors 2.1, 2.2, 2.n, during the installation of an elevator.

Auf der Höhe des obersten Stockwerks 2.n im oberen Bereich des Schachts 3 ist ein Träger 12 schräg in den Schacht 1 hineinragend montiert. Dabei ist ein erstes Ende, hier das linke Ende, des Trägers 12 gelenkig auf dem Boden des obersten Stockwerks 2.n gelagert und ein davon abgewandtes zweites Ende, hier das rechte Ende gegen eine Seitenwand des Schachts 1 angelehnt.At the height of the uppermost floor 2.n in the upper region of the shaft 3, a carrier 12 is mounted obliquely projecting into the shaft 1. In this case, a first end, in this case the left end, of the support 12 is articulated on the floor of the uppermost floor 2.n and a second end facing away therefrom, here the right end leans against a side wall of the shaft 1.

Der Träger 12 verfügt über einen Aufhängungspunkt für ein Hebezeug. Dieser Aufhängungspunkt kann beispielsweise als Öse ausgelegt sein. Das Hebezeug umfasst zumindest ein Tragmittel 13, wie beispielsweise ein Seil, und einen Antrieb 14 der entlang des Tragmittels 13 selbsttreibend verfahrbar ist. Das Tragmittel 13 kann einfach mit einem Haken am Aufhängungspunkt des Trägers 12 eingehängt werden.The carrier 12 has a suspension point for a hoist. This suspension point can be designed, for example, as an eyelet. The hoist comprises at least one support means 13, such as a rope, and a drive 14 which is self-propelled along the support means 13. The support means 13 can be easily hung with a hook on the suspension point of the carrier 12.

Zudem ist eine Installationsplattform 51 an Kabinenführungsschienen 31 verfahrbar montiert. Die Installationsplattform 51 dient während der Installation des Aufzugs als Arbeitsplattform, die entlang den bereits montierten Kabinenführungsschienen 31 verfahrbar ist und von der aus ein Monteur Aufzugskomponenten im Bereich des Schachts 1 montiert. Dazu wird die Installationsplattform 51 auf ihrer Unterseite mit dem Antrieb 14 verbunden. Diese Verbindung kann beispielsweise einfach und zuverlässig über Schraubverbindungen hergestellt werden. Die Installationsplattform 51 umfasst im gezeigten Ausführungsbeispiel drei Teilmodule, nämlich eine Grundplattform 52 mit einer Balustrade 53, die die Stehfläche der Grundplattform 52 begrenzt, eine Führungsverlängerung 55 und eine Dachkonstruktion 54. Die Führungsverlängerung 55 ist an die Grundplattform 52 montierbar und leitet Führungskräfte in einen unteren stabileren Bereich der Kabinenführungsschienen 31, 32 ein. Dies ermöglicht, die Serviceplattform 51 in eine möglichst hohe Arbeitsposition zu verfahren. Die Dachkonstruktion 54 schliesslich bietet Monteuren Schutz vor herabfallenden Gegenständen.In addition, an installation platform 51 is movably mounted on cab guide rails 31. The installation platform 51 is used during the installation of the elevator as a working platform, which is movable along the already mounted cabin guide rails 31 and from which a fitter mounted elevator components in the region of the shaft 1. For this purpose, the installation platform 51 is connected on its underside to the drive 14. This connection can be made, for example, easily and reliably via screw. In the exemplary embodiment shown, the installation platform 51 comprises three submodules, namely a base platform 52 with a balustrade 53 which delimits the standing surface of the base platform 52, a guide extension 55 and a roof construction 54. The guide extension 55 can be mounted on the base platform 52 and guides executives into a lower platform more stable area of the car guide rails 31, 32 a. This makes it possible to move the service platform 51 into the highest possible working position. Finally, the roof construction 54 offers technicians protection against falling objects.

Fig. 2 zeigt den fertig installierten Aufzug. Der Aufzug umfasst zumindest eine Aufzugskabine 10 und ein Gegengewicht 9 zum Ausgleichen der Gewichtskräfte. Dazu sind die Aufzugskabine 10 und das Gegengewicht 9 je an einem Ende eines Traktionsmittel 5 im Aufhängungsverhältnis 1:1 aufgehängt. Das Traktionsmittel 5 läuft im oberen Bereich 3 des Schachts 1 zumindest über eine Traktionsscheibe 6, die mit einem Antrieb 7 wirkverbunden ist, und über eine Umlenkrolle 8. Mittels des Antriebs 7 kann die Aufzugskabine 10 auf die Stockwerke 2.1, 2.2, 2.n verfahren werden. Fig. 2 shows the fully installed elevator. The elevator comprises at least one elevator car 10 and a counterweight 9 for balancing the weight forces. For this purpose, the elevator car 10 and the counterweight 9 are each suspended at one end of a traction means 5 in the suspension ratio 1: 1. The traction means 5 runs in the upper region 3 of the shaft 1 at least via a traction sheave 6, which is operatively connected to a drive 7, and via a deflection pulley 8. By means of the drive 7, the elevator car 10 can travel to the floors 2.1, 2.2, 2.n. become.

Desweiteren ist in Fig. 2 die zur Serviceplattform 51 umfunktionierte Installationsplattform dargestellt. Die Serviceplattform 51 umfasst zumindest die Grundplattform 52 und die Balustrade 53. Hierbei wurden die Dachkonstruktion 54 sowie die Führungsverlängerung 55 vor dem Bereitstellen der Serviceplattform 51 entfernt. Die Serviceplattform 51 wird schliesslich in einem unteren Fahrbereich 4 des Aufzugs, insbesondere einer Schachtgrube 4, für spätere Wartungsarbeiten bereitgestellt.Furthermore, in Fig. 2 represented the converted to the service platform 51 installation platform. The service platform 51 comprises at least the base platform 52 and the balustrade 53. In this case, the roof construction 54 and the guide extension 55 were removed before the service platform 51 was made available. Finally, the service platform 51 is provided in a lower travel area 4 of the elevator, in particular a shaft pit 4, for later maintenance work.

Fig. 3 zeigt die Serviceplattform 51, wie sie über Verbindungselemente 58.1, 58.2 an der Aufzugskabine 10 aufgehängt ist. Als Verbindungselemente 58.1, 58.2 eignen sich Ketten, Kabel, Seile, Riemen oder Zugstäbe. Um die Serviceplattform 51 einfach und zuverlässig an der Aufzugskabine 10 aufhängen zu können, sind sowohl an der Unterseite der Aufzugskabine 10 als auch an der Serviceplattform 51 Verbindungspunkte 11.1, 11.2 bzw. 50.1, 50.2 angeordnet. An diesen Verbindungspunkten 11.1, 11.2, 50.1, 50.2 kann jeweils ein Verbindungselement 58.1, 58.2 eingehakt, eingeklemmt, eingerastet oder verschraubt werden. Vorzugsweise sind vier Verbindungselemente 58.1, 58.2 im Randbereich der Serviceplattform 51 vorgesehen, damit die Serviceplattform 51 für Wartungstechniker einen sicheren Stand bietet. Fig. 3 shows the service platform 51, as it is suspended from the elevator car 10 via connecting elements 58.1, 58.2. As connecting elements 58.1, 58.2 are chains, cables, ropes, belts or tension rods. In order to hang the service platform 51 easily and reliably on the elevator car 10, connecting points 11.1, 11.2 and 50.1, 50.2 are arranged both on the underside of the elevator car 10 and on the service platform 51. At these connection points 11.1, 11.2, 50.1, 50.2 can each be a connecting element 58.1, 58.2 hooked, clamped, snapped or screwed. Preferably, four connection elements 58.1, 58.2 are provided in the edge region of the service platform 51, so that the service platform 51 for maintenance technicians can have a safe Stand offers.
