Abstract
Description
Diese Erfindung betrifft einen Antrieb für eine Liftkabine, die an längsvertikalen Schienen geführt ist. Als Besonderheit ist der Antrieb von der Liftkabine aus wartbar. Die Antriebseinheit ist dabei seitlich, das heisst auf irgendeiner Seite der Liftkabine im Liftschacht angeordnet, wobei die Antriebseinheit und die Kabine aneinander vorbeifahren, was eine möglichst geringe Schachtkopfhöhe und gleichzeitig auch einen minimalen Schachtraumquerschnitt nötig macht, wenn denn der Lift überhaupt in einen Schacht eingebaut wird und nicht an freistehenden längsvertikalen Schienen geführt angeordnet wird.This invention relates to a lift cabin drive which is guided on longitudinal vertical rails. As a special feature, the drive can be maintained from the lift cabin. The drive unit is laterally, that is arranged on any side of the elevator car in the elevator shaft, the drive unit and the car pass each other, which makes the smallest possible shaft head and at the same time a minimum shaft space cross-section necessary if the lift is ever installed in a shaft and is not guided guided on freestanding longitudinal vertical rails.
Herkömmlich sind viele Liftantriebe im oberen Ende des Liftschachtes angeordnet. Zur Wartung dieser Liftantriebe muss ein Liftmonteur auf das Kabinendach der Liftkabine steigen, um Zugang zum Liftantrieb zu bekommen. Das ist grundsätzlich gefährlich, und schon einige Monteur wurden in der Vergangenheit beim Ausführen solcher Kontroll- und Wartungsarbeiten zwischen Liftkabine und Schachtdecke verletzt oder gar durch Zerquetschung getötet. Daher hat der Gesetzgeber strenge Richtlinien erlassen, die ein Verletzen des Liftmonteurs verunmöglichen sollen.Conventionally, many lift drives are arranged in the upper end of the lift shaft. To maintain these lift drives, a lift fitter must climb onto the cabin roof of the lift cabin to gain access to the lift drive. This is fundamentally dangerous, and in the past some mechanics have been injured or even crushed in the past by carrying out such checks and maintenance between the lift cabin and the manhole. Therefore, the legislature has issued strict guidelines that should make it impossible to injure the lift mechanic.
Als zentrale Vorschrift müssen bei neuen Aufzügen die Quetschgefahren in den Endstellungen der Aufzugskabine mittels Freiräumen bzw. Schutznischen vermieden werden. Aufgrund der Formulierung von Ziffer 2.2. in der Aufzugsverordnung und der EG-Aufzugsrichtlinie bedeutet das, dass für den Gesetzgeber die optimale Sicherheit mit einem zwingend vorgeschriebenen Schutzraum erreicht wird. Der Schachtkopf, die Schachtgrube und der Schutzraum sind durch die harmonisierten Normen SN EN 81-1/2:1998 definiert. Danach heisst es dort in Punkt 5.7.1 zum oberen Schutzraum von Treibscheibenaufzügen unter d): Der Raum über der Kabine muss einen auf einer seiner Seiten liegenden Quader mit den Mindestmassen von 0.5m x 0.6m x 0.8m aufnehmen können, und zwar permanent. Ein zusätzlicher Freiraum kann temporär erstellt werden, wenn sichergestellt ist, dass der Liftschacht nur dann zugänglich ist, wenn dieser Freiraum erstellt ist. Die Höhe dieses zusätzlichen Freiraumes mit Grundfläche 0.48m x 0.25m ist abhängig von der Maximalgeschwindigkeit der Liftkabine und berechnet sich in Metern zu 1 + 0.035 x v2, wobei v in [m/s] eingesetzt wird. Diese Vorschriften gelten und müssen auch dann eingehalten werden, wenn es für die Wartung des Liftes überhaupt nicht nötig ist, auf das Kabinendach zu steigen.The central requirement for new elevators is the risk of crushing in the end positions of the elevator car by means of clearances or shelter niches are avoided. Due to the wording of point 2.2. in the elevator regulation and the EC elevator directive this means that for the legislature the optimal safety with a compulsory prescribed protection area is achieved. The shaft head, the shaft pit and the shelter are defined by the harmonized standards SN EN 81-1 / 2: 1998. According to this, in point 5.7.1, it is said to be the upper shelter of traction sheave lifts under d): The space above the cabin must be able to accommodate a cuboid lying on one of its sides with minimum dimensions of 0.5mx 0.6mx 0.8m, permanently. An additional free space can be created temporarily if it is ensured that the lift shaft is accessible only when this clearance is created. The height of this additional free space with footprint 0.48mx 0.25m depends on the maximum speed of the lift cabin and is calculated in meters to 1 + 0.035 xv 2 , where v is used in [m / s]. These regulations apply and must be complied with even if it is not necessary at all to climb onto the cabin roof to maintain the lift.
Bisher war es allerdings kaum nötig, ein Begehen der Liftkabine (Kabinendach) zu vermeiden. Die meisten Liftantriebe befinden sich im oberen Ende des Liftschachtkopfes und daher muss die Liftkabine (Kabinendach) begehbar sein, um die Wartungsarbeiten auszuführen. Anders verhält es sich bei einer Liftkonstruktion, bei welcher das obere Ende des Schachtkopfes völlig frei bleibt. Von der Architektur her kommt der zunehmende Wunsch, auf unschöne Lichtschachtköpfe auf den Gebäuden verzichten zu können. Das aber stellt die Lifthersteller vor neue Herausforderungen, gerade weil mit jeder Konstruktion auch die geltenden Aufzugsverordnungen erfüllt werden müssen. Neuste Liftkonstruktionen erlauben eine minimale Schachtkopfhöhe von bloss noch 280cm. Das ist das Mass vom obersten Stockwerkboden bis hinauf an die Unterseite des Liftschachtkopfes, das heisst an die Decke des Liftschachtes. Ein dort einzubauender Lift weist zum Beispiel eine Kabine von 220cm Innenhöhe auf. Ca. 10cm werden für die Überfahrt oben über der Kabine benötigt. Für den Lifttürenantrieb benötigt es zusätzlich gewisse Höhe. Somit verbleiben in der obersten normalen Liftposition noch 5cm übrig. Diese werden als Sicherheitspuffer benötigt. Wenn der Lift mit grosser Last im obersten Stockwerk anhält, genau auf Stockwerkhöhe, und dann entlastet wird, so kann sich die Kabine aufgrund der Elastizität der Tragseite noch um einige cm anheben. Auch dann muss noch ein Spalt breit Luft bis zum Liftschachtkopf vorhanden sein, damit in keinem Fall die Liftkabine an demselben anschlagen kann. Bei dieser Konstellation mit Liftkabinenhöhe von 220cm plus die Minimalhöhe des liegenden vorgeschriebenen Quaders von 0.50m, das heisst 220cm + 50cm + 10cm Überfahrt, ergibt sich gerade diese Schachtkopfhöhe von 280cm. Es besteht der Wunsch, dieses Mass des Schachkopfes noch weiter zu reduzieren, denn die übliche Stockwerkhöhe in Wohnbauten beträgt 240cm. Dann kommt die Betondecke und allenfalls die Flachdachkonstruktion darüber. Mit Liftschachtköpfen von 280cm ab dem obersten Geschossboden ist man in vielen Fällen immer noch höher als die zugehörige Dachkonstruktion, sodass der Liftkopf immer hoch aus dem Dach herausragt. Gerade das soll aber vermieden werden.So far, however, it was hardly necessary to avoid committing the elevator cabin (cab roof). Most lift drives are located in the upper end of the lift shaft head and therefore the lift cabin (cabin roof) must be accessible for maintenance. The situation is different with a lift construction in which the upper end of the shaft head remains completely free. From the architecture comes the increasing desire to be able to do without unsightly light shaft heads on the buildings. However, this presents the lift manufacturers with new challenges, precisely because with every construction, the applicable lift regulations must be met. Latest lift constructions allow a minimum shaft head height of only 280cm. This is the measure of the top floor floor up to the bottom of the lift shaft head, that is to the ceiling of the elevator shaft. For example, a lift to be installed has a cabin of 220cm inside height. Approximately 10cm are needed for crossing above the cabin. For the lift door drive, it also requires certain height. Thus remain in the top normal lift position still 5cm left. These are needed as a safety buffer. If the lift stops at the top floor with a heavy load, exactly at floor level, and then is relieved, the cabin can still lift by a few cm due to the elasticity of the support side. Even then there must still be a gap wide air up to the lift shaft head, so that in no case can strike the elevator car at the same. In this constellation with elevator cabin height of 220cm plus the minimum height of the lying prescribed cuboid of 0.50m, which means 220cm + 50cm + 10cm crossing, this shaft height of 280cm results straight. There is a desire to further reduce this measure of the chess head, because the usual floor height in residential buildings is 240cm. Then comes the concrete ceiling and possibly the flat roof construction above. With lift shaft heads of 280cm from the top floor you are in many cases still higher than the corresponding roof construction, so that the lift head always protrudes high out of the roof. But that is exactly what should be avoided.
Ein weiterer Nachteil herkömmlicher Antriebe für Liftkabinen ist darin zu sehen, dass mit Elektromotoren, Getrieben und Seilscheiben gearbeitet wird. Konstruktionsbedingt gelingt es in vielen Fällen nicht, einen guten Massenausgleich zu erhalten. Das macht es dann nötig, dass die Antriebskonstruktionen sehr stark mit dem Liftschacht verbunden werden müssen, sodass die auftretenden Reaktionskräfte absorbiert werden können.Another disadvantage of conventional drives for lift cabins is the fact that it works with electric motors, transmissions and sheaves. Due to the design, in many cases it is not possible to obtain a good mass balance. This then makes it necessary that the drive structures must be very strongly connected to the lift shaft, so that the reaction forces occurring can be absorbed.
Die Aufgabe der vorliegenden Erfindung ist es deshalb, einen Antrieb für eine Liftkabine zu schaffen, welcher bei einer bestimmten Liftkabinenhöhe eine minimale Schachtkopfhöhe verlangt und der weiter aus der Liftkabine heraus wartbar ist. Der Antrieb soll einen minimalen Raum zwischen der Liftkabine und Schachtwand beanspruchen, wo eine solche vorhanden ist, und eine optimale Gewichtsverteilung zwischen der Liftkabine und ihrer Nutzlast sowie dem Gegengewicht bieten, sodass kaum mehr Kräfte auf die Schachtwand wirken, an welcher die Antriebskonstruktion gesichert ist. Weiter soll der Antrieb möglichst auf verschiedene Lasten anpassbar sein und bei verglasten Liftschächten als Werbeträgerfläche für flächige oder dreidimensionale Werbesujets einsetzbar sein.The object of the present invention is therefore to provide a drive for a lift cabin which requires a minimum shaft head height at a certain elevator car height and which can be maintained further from the elevator car. The drive should take up a minimal space between the elevator car and shaft wall, where such exists, and provide optimum weight distribution between the elevator car and its payload and the counterweight, so that hardly more forces act on the shaft wall on which the drive structure is secured. Next, the drive should be as possible adaptable to different loads and used in glass elevator shafts as an advertising surface for flat or three-dimensional Werbesujets be.
Diese Aufgabe wird gelöst von einem Antrieb für eine Liftkabine und deren Gegengewicht, die je an einem Paar von vertikalen Führungsschienen geführt sind, dadurch gekennzeichnet, dass der Antrieb ein getriebeloser Traktionsantrieb mit stationärem Stator und äusserem, drehenden und innen mit Permanentmagneten bestückten Treibrohr ist, um welches die Tragmittel für die Liftkabine und das Gegengewicht in entsprechend gestalteten Oberflächen für die Aufnahme der Tragmittel geführt sind, und welcher Traktionsantrieb als Einheit mit seinem Treibrohr an den Tragmitteln hängend und sonst freistehend auf einem Führungsrahmen angeordnet ist, wobei der Führungsrahmen zwischen den vertikalen Führungsschienen geführt ist, die oben mit einer Brücke verbunden sind, und dass unterhalb des Führungsrahmens ein an ihm hängender, ebenfalls an den beiden vertikalen Führungsschienen geführter Rahmen befestigt ist, zur Aufnahme eines bedarfsweise festzulegenden Gegengewichtes zur Liftkabine.This object is achieved by a drive for a lift cage and its counterweight, which are each guided on a pair of vertical guide rails, characterized in that the drive is a gearless traction drive with stationary stator and outer, rotating and inside equipped with permanent magnets propellant to which the support means for the elevator car and the counterweight are guided in correspondingly shaped surfaces for receiving the support means, and which traction drive is arranged as a unit with its drive tube hanging on the suspension means and otherwise free-standing on a guide frame, wherein the guide frame between the vertical guide rails is that are connected at the top with a bridge, and that below the guide frame a hanging on him, also guided on the two vertical guide rails frame is attached, for receiving a if necessary to be determined counterweight to the lift cage ine.
