Abstract

The lift has a lift car and counterweight interconnected by a cable (2) guided over a pulley, and the counterweight compensates for the natural weight of the lift car and a part of the net load. The counterweight (1) is variable in overall weight by at least one additional weight (8) which is detachable from the counterweight in the lift pit. The counterweight has side plates (5,6) which pass by the additional weight in the pit, whereby each side plate has a coupling device (12) to create a releasable connection between the counterweight and additional weight. An independent claim is included for a method for the compensating of a natural weight of a lift car and part of the load by using an additional weight.

Description

Die Erfindung betrifft einen Aufzug mit einer Aufzugskabine und einem Gegengewicht, wobei die Aufzugskabine und das Gegengewicht mittels eines über eine Seilscheibe geführten Seils miteinander verbunden sind und das Gegengewicht das Eigengewicht der Aufzugskabine und einen Teil der Nutzlast kompensiert.The invention relates to an elevator with an elevator car and a counterweight, wherein the elevator car and the counterweight are connected to each other by means of a guided via a pulley rope and the counterweight compensates the weight of the elevator car and a portion of the payload.

Aus der Offenlegungsschrift DE 198 42 052 ist ein Aufzug mit einer Aufzugskabine und einem Gegengewicht bekannt geworden, wobei die Aufzugskabine mittels eines über eine Treibscheibe geführten Tragseils mit dem Gegengewicht verbunden ist. Üblicherweise wird mit dem Gegengewicht 50% der Nutzlast und das Kabinengewicht ausgeglichen. Im vorliegenden Fall kompensiert das Gegengewicht das Kabinengewicht und weniger als 40% der Nutzlast. Bei voller Nutzlast wird der Aufzug mit der kleiner gewählten Antriebsmaschine und mit einem reduzierten Betriebsgeschwindigkeitsprofil betrieben.From the Laid-open publication DE 198 42 052 an elevator has become known with an elevator car and a counterweight, wherein the elevator car is connected to the counterweight by means of a carrying cable guided via a traction sheave. Typically, the counterweight balances 50% payload and cabin weight. In the present case, the counterweight compensates for the cabin weight and less than 40% of the payload. At full payload, the elevator is operated with the smaller selected prime mover and with a reduced operating speed profile.

Ein Nachteil der bekannten Einrichtung liegt darin, dass das Gegengewicht unter der Annahme dimensioniert ist, dass die volle Nutzlast nur selten zu transportieren ist. Die Leistungsfähigkeit des Aufzuges wird mit dem reduzierten Betriebsgeschwindikeitsprofil immer dann reduziert wenn die Nachfrage an Transportleistung am grössten ist. Bei einer Unterkompensation treten folgende Probleme auf: Bremsen, Fangvorrichtung und Puffer müssen für Q-A·Q ausgelegt sein. (Q = Nutzlast, A = Kompensationsfaktor, beispielsweise 40% bzw. 0,4). Ausserdem ist bei einer Unterkompensation das Problem der Traktion zu lösen, selbst wenn nur wenige Fahrten mit Kabinenvolllast durchzuführen sind. Die Traktion muss auch für Q-A·Q ausgelegt sein. Der Motor muss ein Drehmoment proportional zu Q-A·Q erzeugen, wobei der erforderliche Strom selbst bei reduzierter Geschwindigkeit ansteigt. Überlastungen des Motors bzw. des Umrichters sind nicht ausgeschlossen. Bei Abwärtsfahrten entsteht mehr zu rekuperierende Energie, die beispielsweise in einem Bremswiderstand in Wärme umgewandelt werden muss.A disadvantage of the known device is that the counterweight is dimensioned on the assumption that the full payload is only rarely to be transported. The efficiency of the elevator is reduced with the reduced operating speed profile whenever the demand for transport performance is greatest. Undercompensation causes the following problems: Brakes, safety gear and buffers must be designed for QA · Q. (Q = payload, A = compensation factor, for example 40% or 0.4). In addition, the problem of traction is to be solved in an undercompensation, even if only a few trips are carried out with full cabin load. The traction must also be designed for QA · Q. The motor must generate a torque proportional to QA · Q, with the required current increasing even at reduced speed. Overloading of the motor or the inverter is not excluded. Driving downhill creates more energy to be recuperated which, for example, has to be converted into heat in a braking resistor.

Aus der Schrift US 4 236 605 ist eine Aufzugsanlage bekannt geworden, wobei ein Windenantrieb eine Aufzugskabine und ein Gegengewicht antreibt. Die Aufzugskabine und das Gegengewicht sind mittels eines über eine Umlenkrolle geführten Seils miteinander verbunden. Das Gegengewicht ist im Gewicht veränderbar ausgestaltet. Zur Beschleunigung der Aufzugskabine in Aufwärtsrichtung hat das Gegengewicht maximales Gewicht. Dann wird ein Gegengewichtselement deponiert und die Aufzugskabine fährt mit konstanter Geschwindigkeit. Zur Verzögerung der Aufzugskabine wird ein weiteres Gegengewichtselement deponiert. Bei einer Fahrt der Aufzugskabine in Abwärtsrichtung werden die Gewichtselemente vom Gegengewicht wieder aufgenommen.From the Scriptures US 4,236,605 an elevator system has become known, wherein a winch drive drives an elevator car and a counterweight. The elevator car and the counterweight are connected to each other by means of a rope guided over a pulley. The counterweight is variable in weight. To accelerate the elevator car in the upward direction, the counterweight has maximum weight. Then a counterweight element is deposited and the elevator car moves at a constant speed. To delay the elevator car another counterweight element is deposited. When driving the elevator car in the downward direction, the weight elements are resumed by the counterweight.

Nachteilig bei dieser Einrichtung ist das Deponieren bzw. das Aufnehmen von Gewichtselementen während der Fahrt. Die Veränderung des Gegengewichtes während der Fahrt verursacht erhebliche Geräusche im Aufzugsschacht und macht eine ruckfreie Fahrt der Aufzugskabine unmöglich. Ausserdem ist diese Einrichtung nur funktionsfähig, wenn das Verkehrsaufkommen den Veränderungsmöglichkeiten des Gegengewichtes entspricht, bzw. wenn die Aufzugskabine im Erdgeschoss volle Nutzlast hat und auf der Fahrt nach oben entleert wird.A disadvantage of this device is the depositing or recording of weight elements while driving. The change in the counterweight while driving causes considerable noise in the elevator shaft and makes a jerk-free ride of the elevator car impossible. In addition, this facility is only functional if the traffic volume changes the possibilities of Counterweight or when the elevator car on the ground floor has full payload and is emptied on the way up.

Aus der Schrift JP 06263368 ist ein im Gewicht veränderbares Gegengewicht für einen Aufzug bekannt geworden. An der Unterseite des Hauptgewichtes ist eine Kopplungseinrichtung vorgesehen, mittels der ein Zusatzgewicht mit dem Hauptgewicht verbindbar ist. Das Zusatzgewicht wird bei hohem Verkehrsaufkommen angekoppelt und bei schwachem Verkehr in der Schachtgrube deponiert.From the Scriptures JP 06263368 a weight-adjustable counterweight for a lift has become known. On the underside of the main weight, a coupling device is provided, by means of which an additional weight can be connected to the main weight. The additional weight is coupled with heavy traffic and deposited in the shaft pit in poor traffic.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in Anspruch 1 gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtung zu vermeiden und einen Aufzug mit optimiertem Ausgleich zwischen Aufzugskabine und Gegengewicht zu schaffen.The invention aims to remedy this situation. The invention, as characterized in claim 1 solves the problem of avoiding the disadvantages of the known device and to provide a lift with optimized balance between the elevator car and counterweight.

Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.Advantageous developments of the invention are specified in the dependent claims.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass beachtliche Energieeinsparungen möglich sind. Beispielsweise wird der Aufzug bei Spitzenverkehr mit einer 1000 kg Nutzlast betrieben und bei Normalverkehr mit einer 630 kg Nutzlast, wobei bei einem 50% Nutzlastausgleich 500 kg bzw. 315 kg vom Gegengewicht kompensiert werden. Falls bei der kleineren Nutzlast zuviele Passagiere zusteigen, erzeugt die Aufzugssteuerung einen Überlastalarm und fordert zum Aussteigen auf. Mit optimal kompensierten Aufzugskabinen (möglichst kleine Gewichtsdifferenz zwischen beladener Aufzugskabine und Gegengewicht) ist zudem die Gefahr von Schlupf zwischen Tragseil und Treibscheibe geringer. Die Gewichtsanpassung im Gegengewicht erfolgt durch Aufnahme oder Abgabe mindestens eines Zusatzgewichtes und kann manuell oder automatisch beispielsweise aufgrund einer Verkehrsmessung oder eines Spitzenverkehr berücksichtigenden Zeitplanes erfolgen.The advantages achieved by the invention are essentially to be seen in the fact that considerable energy savings are possible. For example, the elevator is operated at peak traffic with a 1000 kg payload and in normal traffic with a 630 kg payload, with a 50% payload compensation 500 kg or 315 kg are compensated by the counterweight. If too many passengers board at the smaller payload the elevator control an overload alarm and asks to get off. With optimally compensated elevator cars (the smallest possible weight difference between loaded elevator car and counterweight), the risk of slippage between the carrier cable and the traction sheave is also lower. The weight adjustment in the counterweight is carried out by receiving or delivering at least one additional weight and can be done manually or automatically, for example, due to a traffic measurement or a peak traffic schedule.

Die erfindungsgemässe Einrichtung verbessert die Energieeffizienz von schlecht ausgelasteten Aufzugskabinen wesentlich. 99,9% aller Fahrten werden mit weniger als 80% Nutzlast durchgeführt und 80% aller Fahrten werden mit weniger als 20% Nutzlast durchgeführt. Mit dem veränderbaren Gegengewicht kann dem entgegengewirkt werden. Ausserdem kann die Antriebsmaschine auf kleinere Kompensationsfaktoren bzw. auf kleinere Nutzlastausgleiche ausgelegt werden, falls ein vertretbarer Überlastfaktor bei einzelnen Fahrten mit Volllast vertretbar ist.The device according to the invention substantially improves the energy efficiency of poorly utilized elevator cars. 99.9% of all journeys are made with less than 80% Payload carried out and 80% of all trips are carried out with less than 20% payload. With the variable counterweight can be counteracted. In addition, the prime mover can be designed for smaller compensation factors or for smaller payload compensations if a justifiable overload factor is justifiable for individual trips at full load.

Anhand der beiliegenden Figuren wird die vorliegende Erfindung näher erläutert.Reference to the accompanying figures, the present invention will be explained in more detail.

Es zeigen:

  • Fig. 1 ein Gegengewicht einer Aufzugsanlage,
  • Fig. 2 ein Zusatzgewicht zum Gegengewicht und
  • Fig. 3 das Gegengewicht mit dem Zusatzgewicht gekoppelt.
Show it:
  • Fig. 1 a counterweight of an elevator installation,
  • Fig. 2 an additional weight to the counterweight and
  • Fig. 3 the counterweight coupled with the additional weight.

Fig. 1 zeigt ein Gegengewicht 1 einer Aufzugsanlage, das in einem Aufzugsschacht entlang von Führungsschienen verfahrbar ist. Eine entlang von Führungsschienen im Aufzugsschacht verfahrbare Aufzugskabine ist mittels eines über eine Seilscheibe geführten Seils 2 mit dem Gegengewicht 1 verbunden, wobei das Seil 2 am oberen Joch angreift. Je nach Seilführung kann am Joch 3 anstelle des Seilendes mindestens eine Umlenkrolle angeordnet sein. Fig. 1 shows a counterweight 1 an elevator system, which is movable in a lift shaft along guide rails. An elevator car which can be moved along guide rails in the elevator shaft is connected to the counterweight 1 by means of a cable 2 guided via a cable pulley, the cable 2 engaging the upper yoke. Depending on the cable guide, at least one guide roller may be arranged on the yoke 3 instead of the cable end.

Das Gegengewicht 1 besteht aus einem oberen Joch 3, einem unteren Joch 4 , einem ersten Seitenschild 5, einem zweiten Seitenschild 6 und aus Gewichtselementen 7. Die im Querschnitt beispielsweise U-förmigen Seitenschilder 5,6 sind mit den Jochs 3,4 verbunden und weisen nach unten hin je eine freie Verlängerung 5.1,6.1 auf.The counterweight 1 consists of an upper yoke 3, a lower yoke 4, a first side shield 5, a second Side plate 6 and of weight elements 7. The cross-sectionally, for example, U-shaped side plates 5,6 are connected to the yokes 3,4 and have downwards depending on a free extension 5.1,6.1.

Fig. 2 zeigt ein an das Gegengewicht 1 ankoppelbares Zusatzgewicht 8, das aus einem Joch 9 mit Stangen 10 besteht. Gewichtselemente 11 sind auf die Stangen 10 aufsteckbar. An der Schmalseite des Jochs 9 sind Bohrungen 9.1 vorgesehen, die der Ankopplung des Zusatzgewichtes 8 an das Gegengewicht 1 dienen. Fig. 2 shows an attachable to the counterweight 1 additional weight 8, which consists of a yoke 9 with rods 10. Weight elements 11 are attachable to the rods 10. On the narrow side of the yoke 9 holes 9.1 are provided, which serve to couple the additional weight 8 to the counterweight 1.

Fig. 3 zeigt das Gegengewicht 1 in der untersten Lage, bei der die Aufzugskabine auf dem obersten Stockwerk steht. Die freien Verlängerungen 5.1,6.1 der Seitenschilder 5,6 sind an den Schmalseiten des in der Schachtgrube angeordneten Zusatzgewichtes 8 vorbeigefahren. Falls das Gesamtgewicht des Gegengewichtes 1 beispielsweise aufgrund einer höheren Nutzlast der Aufzugskabine erhöht werden muss, wird eine Kopplungseinrichtung 12 betätigt. Die Kopplungseinrichtung 12 stellt eine lösbare Verbindung zwischen dem Gegengewicht 1 und dem Zusatzgewicht 8 her und ist an den Verlängerungen 5.1,6.1 der Seitenschilder 5,6 angeordnet. Fig. 3 shows the counterweight 1 in the lowest position, in which the elevator car is on the top floor. The free extensions 5.1,6.1 of the side plates 5,6 are passed on the narrow sides of the arranged in the shaft pit additional weight 8. If the total weight of the counterweight 1, for example, must be increased due to a higher payload of the elevator car, a coupling device 12 is actuated. The coupling device 12 establishes a detachable connection between the counterweight 1 and the additional weight 8 and is arranged on the extensions 5.1, 6. 1 of the side plates 5, 6.

Es kann auch mehr als ein Zusatzgewicht 8 vorgesehen sein. In diesem Fall sind die Zusatzgewichte 8 übereinander angeordnet und können einzeln an das Gegengewicht 1 angekoppelt bzw. abgekoppelt werden.It can also be provided more than an additional weight 8. In this case, the additional weights 8 are arranged one above the other and can be individually coupled or disconnected to the counterweight 1.

Als Kopplungseinrichtung 12 kann beispielsweise je Seitenschild 5,6 ein motorisierter Schraubendreher vorgesehen sein, der eine Schraube durch das Seitenschild 5.1,6.1 in die Bohrung 9.1 dreht bzw. aus der Bohrung 9.1 entfernt.As a coupling device 12, for example, per side shield 5.6 a motorized screwdriver may be provided which rotates a screw through the side plate 5.1,6.1 in the bore 9.1 and removed from the bore 9.1.

Als weitere Ausführungsvariante der Kopplungseinrichtung 12 kann je Seitenschild 5,6 ein elektromechanisch betätigbarer Greifer vorgesehen sein, der das Joch 9 des Zusatzgewichtes 8 untergreift bzw. freisetzt.As a further embodiment variant of the coupling device 12, an electromechanically actuable gripper may be provided per side shield 5, 6 which engages or releases the yoke 9 of the additional weight 8.

Als weitere Ausführungsvariante der Kopplungseinrichtung 12 kann je Seitenschild 5,6 mindestens ein verrastbarer Bolzen vorgesehen sein, der mittels elektromechanischem Stössel durch das Seitenschild 5,6 in die Bohrung 9.1 vorschiebbar ist bzw. aus der Bohrung 9.1 entfernbar ist.As a further embodiment variant of the coupling device 12, at least one latchable bolt can be provided per side shield 5, 6, which can be pushed into the bore 9.1 by means of electromechanical plunger through the side plate 5, 6 or can be removed from the bore 9.1.

Es kann auch eine manuelle Kopplungseinrichtung 12 vorgesehen sein, indem beispielsweise verrastbare, manuell betätigbare Bolzen das Gegengewicht 1 mit dem Zusatzgewicht 8 an den Seitenschildern 5,6 verbinden bzw. lösen. Die Bolzen können beispielsweise mittels Bowdenzug betätigbar sein.It may also be a manual coupling device 12 may be provided by, for example, lockable, manually operable bolts connect the counterweight 1 with the additional weight 8 on the side plates 5.6 or solve. The bolts can be actuated for example by means of Bowden cable.
