Description

Die Erfindung betrifft eine Evakuiervorrichtung für Aufzüge einer Aufzugsgruppe, wobei eine Notsteuerungseinrichtung vorgesehen ist, die bei Auftreten eines Notfalles zwecks Evakuierung von in einer Aufzugskabine befindlichen Fahrgästen aktiviert werden kann.The invention relates to an evacuation device for elevators of an elevator group, an emergency control device being provided which can be activated in the event of an emergency for the purpose of evacuating passengers in an elevator car.

Derartigen Evakuiervorrichtungen liegt normalerweise das Funktionsprinzip zugrunde, eine Aufzugskabine nach einem durch eine Betriebsstörung verursachten unbeabsichtigten Halt zwischen zwei Stockwerken zum nächstgelegenen Stockwerk zu bringen, um den eingeschlossenen Fahrgästen das Aussteigen zu ermöglichen. Eine häufige Ursache für Betriebsstörungen, sind Netzspannungsausfälle. In solchen Fällen kann, wie beispielsweise mit der US-PS 3 506 095 bekannt geworden, der Antriebsmotor an eine Hilfsspannungsquelle geschaltet und die betroffene Aufzugskabine zum nächsten Stockwerk gefahren werden.Such evacuation devices are normally based on the functional principle of bringing an elevator car between two floors to the next floor after an unintentional stop caused by a malfunction in order to enable the enclosed passengers to get out. A common cause of malfunctions is mains voltage failures. In such cases, as has become known, for example, from US Pat. No. 3,506,095, the drive motor can be connected to an auxiliary voltage source and the elevator car concerned can be moved to the next floor.

Aus der GB-A 2 017 346 ist es bekannt, bei Betriebsstörungen, die durch Netzspannungsausfall oder Defekte der elektrischen Steuerung verursacht sind, den Antriebsmotor an eine Hilfsspannungsquelle zu schalten, wobei automatisch diejenige Fahrtrichtung für die Notfahrt ermittelt wird, welche weniger Energie verbraucht. Bei einer anderen, mit der DE-A 1 506 484 bekannt gewordenen Einrichtung ist für die Notfahrt ein Hilfsmotor vorgesehen, so dass die betroffene Aufzugskabine auch bei einem Defekt des Antriebsmotors bewegt werden kann. Auch hierbei wird die leistungsmässig günstigere Fahrtrichtung gewählt, so dass der Hilfsmotor und die Hilfsspannungsquelle klein dimensioniert werden können. Ist die eingetretene Betriebsstörung derart, dass die Aufzugskabine beispielsweise unter Auslösung der Fangvorrichtung zwischen zwei Stockwerken zum Stillstand gekommen ist, so ist die Wahl der Fahrtrichtung für die Notfahrt nicht mehr ohne weiteres möglich. Bei Defekten, bei denen die betroffene Aufzugskabine sich weder in der einen noch in der anderen Richtung bewegen lässt, sind vorstehend erwähnte Einrichtungen ebenfalls nicht geeignet. In solchen Fällen kann von der Alarmauslösung bis zur Befreiung sehr viel Zeit vergehen, so dass die eingeschlossenen Fahrgäste grossen psychischen Belastungen ausgesetzt sind.From GB-A 2 017 346 it is known to switch the drive motor to an auxiliary voltage source in the event of malfunctions which are caused by mains voltage failure or defects in the electrical control, the direction of travel for the emergency journey which uses less energy being automatically determined. In another device which has become known from DE-A 1 506 484, an auxiliary motor is provided for emergency travel, so that the elevator car concerned can also be moved if the drive motor is defective. Here, too, the direction of travel which is more favorable in terms of performance is selected, so that the auxiliary motor and the auxiliary voltage source can be dimensioned small. If the malfunction that has occurred is such that the elevator car has come to a standstill between two floors, for example when the safety gear is triggered, then it is no longer possible to choose the direction of travel for the emergency drive. The above-mentioned devices are also unsuitable for defects in which the elevator car concerned cannot be moved in either direction. In such cases, it can take a long time from triggering the alarm to being released, so that the trapped passengers are exposed to great psychological stress.

Es ist daher Aufgabe der Erfindung, zwecks Vermeidung vorstehend erwähnter Nachteile eine Evakuiervorrichtung gemäss Oberbegriff zu schaffen, bei der eine von einem Notfall betroffene Aufzugskabine nicht in Bewegung gesetzt werden muss und die eingeschlossenen Fahrgäste trotzdem in kürzester Zeit befreit werden können.It is therefore an object of the invention to provide an evacuation device according to the preamble in order to avoid the disadvantages mentioned above, in which an elevator car affected by an emergency does not have to be set in motion and the enclosed passengers can still be freed in a very short time.

Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichnete Erfindung gelöst. Hierbei wird für die Evakuierung der in einer von einem Notfall betroffenen Aufzugskabine einer Aufzugsgruppe befindlichen Personen eine benachbarte Aufzugskabine verwendet. Zu diesem Zweck sind an den einander zugewandten Seitenwänden der in einem gemeinsamen Aufzugsschacht geführten Aufzugskabinen Übergangseinrichtungen angeordnet, die verriegelbare Türen aufweisen. Nach Eintritt des Notfalles und Aktivierung einer Notsteuerungseinrichtung wird die der blockierten Aufzugskabine benachbarte Aufzugskabine auf deren Niveau gesteuert, worauf die Türen der Übergangseinrichtungen beider Aufzugskabinen entriegelt und geöffnet werden und die Fahrgäste der blockierten Aufzugskabine in die benachbarte Aufzugskabine umsteigen können. Nach dem Umsteigen werden die Türen wieder geschlossen und verriegelt und die Notsteuerungseinrichtung deaktiviert, so dass die Fahrgäste zu beliebigen Stockwerken fahren können.This object is achieved by the invention characterized in claim 1. In this case, an adjacent elevator car is used for the evacuation of the people in an elevator car of an elevator group affected by an emergency. For this purpose, transition devices which have lockable doors are arranged on the mutually facing side walls of the elevator cars guided in a common elevator shaft. After an emergency occurs and an emergency control device is activated, the elevator car adjacent to the blocked elevator car is controlled at its level, whereupon the doors of the transition devices of both elevator cars are unlocked and opened and the passengers of the blocked elevator car can change to the adjacent elevator car. After changing trains, the doors are closed and locked again and the emergency control device deactivated so that passengers can travel to any floor.

Die mit der Erfindung erzielten Vorteile liegen insbesondere darin, dass die Evakuierung von Personen aus blockierten und ohne Beseitigung der Störungsursache nicht in Bewegung setzbaren Aufzugskabinen in kürzester Zeit sicher und ohne Hilfe von Bedienungspersonal stattfinden kann, so dass grössere psychische Belastungen der eingeschlossenen Fahrgäste vermieden werden. Weitere Vorteile sind darin zu sehen, dass bei Notfällen aufgrund mechanischer Defekte oder einer Spannungsunterbrechung der blockierten Aufzugskabine, eine allenfalls vorgesehene Hilfsspannungsquelle nicht beansprucht werden muss. Auch ist es vorteilhaft, dass die befreiten Fahrgäste nach dem Umsteigen zu Stockwerken ihrer Wahl fahren können.The advantages achieved by the invention are, in particular, that the evacuation of people from blocked elevator cars that cannot be moved without eliminating the cause of the fault can take place in a very short time without the help of operating personnel, so that greater psychological stress on the trapped passengers can be avoided. Further advantages can be seen in the fact that in the event of emergencies due to mechanical defects or a voltage interruption in the blocked elevator car, an auxiliary voltage source that may be provided need not be used. It is also advantageous that the exempted passengers can travel to floors of their choice after changing.

The fourth gate arrangement 40 is connected on the output side to four power switching elements 41-44, for example in the form of transistor switches, via which the directional protection devices 23, 24 of the elevator cars B, C as a function of start and stop signals formed in the fourth gate arrangement 40 for opening and closing Downward emergency trips can be controlled.

Mit 45 ist eine fünfte Gatteranordnung bezeichnet, die eingangsseitig mit den den Aufzugskabinen B, C zugeordneten Ausgängen des Dekodierers 33 und den Notfallkontakten 20a, 20b, 20c verbunden ist. Ausgangsseitig steht die fünfte Gatteranordnung 45 mit drei Leistungsschaltelementen 46a, 46b, 46c, beispielsweise in Form von Transistorschaltern in Verbindung, über welche die Umschaltrelais 30a, 30b, 30c angesteuert werden können. Die fünfte Gatteranordnung 45 und die drei Leistungsschaltelemente 46a, 46b, 46c bilden zusammen mit den drei Registern 32a, 32b, 32c und dem Dekodierer 33 eine Kabinenauswahlschaltung, mittels welcher eine von einem Notfall betroffene Aufzugskabine von der normalen Fahrsteuerung abgeschaltet und eine für die Notfahrt ausgewählte Aufzugskabine an eine aus den Elementen 34a-44 der Notsteuerungseinrichtung 18 gebildete Notfahrschaltung angeschaltet werden kann. Die Kabinenauswahlschaltung ist derart konzipiert, dass bei blockierten Aufzugskabinen A, C die Aufzugskabine B und bei blockierter Aufzugskabine B die Aufzugskabine C für die Evakuierung ausgewählt wird. Über zwei weitere Eingänge können der fünften Gatteranordnung 45 nach Beendigung der Evakuierung Signale Reset b, Reset c zugeführt werden, mittels welchen die beteiligten Aufzugskabinen wieder an die normale Fahrsteuerung geschaltet werden können.45 designates a fifth gate arrangement which is connected on the input side to the outputs of the decoder 33 assigned to the elevator cars B, C and to the emergency contacts 20a, 20b, 20c. On the output side, the fifth gate arrangement 45 is connected to three power switching elements 46a, 46b, 46c, for example in the form of transistor switches, by means of which the changeover relays 30a, 30b, 30c can be controlled. The fifth gate arrangement 45 and the three power switching elements 46a, 46b, 46c together with the three registers 32a, 32b, 32c and the decoder 33 form a car selection circuit, by means of which an elevator car affected by an emergency is switched off by the normal driving control and one selected for emergency travel The elevator car can be connected to an emergency drive circuit formed from the elements 34a-44 of the emergency control device 18. The car selection circuit is designed such that the elevator car B is selected for the blocked elevator cars A, C and the elevator car C is selected for the evacuation if the elevator car B is blocked. After completion of the evacuation, signals reset b, reset c can be fed to the fifth gate arrangement 45 via two further inputs, by means of which the elevator cars involved can be switched back to the normal travel control.

An den Ausgängen des Dekodierers 33 sind optische und/oder akustische Signaleinrichtungen 47b, 47c angeschlossen, die in den Aufzugskabinen B, C angeordnet sind, und die bei Auswahl einer Aufzugskabine B oder C für eine Notfahrt aktiviert werden.Optical and / or acoustic signal devices 47b, 47c are connected to the outputs of the decoder 33, which are arranged in the elevator cars B, C and which are activated when an elevator car B or C is selected for an emergency journey.

Die vorstehend beschriebene Evakuiervorrichtung arbeitet wie folgt:The evacuation device described above works as follows:

Es möge angenommen sein, dass die Aufzugskabine A infolge eines Spannungsunterbruches der Steuerung von einem Notfall betroffen wurde und zwischen zwei Stockwerken blockiert ist. In diesem Fall wird bei Betätigung des in der Aufzugskabine A angeordneten Alarmknopfes in der Pförtnerloge des Gebäudes Alarm ausgelöst und der Notfallkontakt 20a geschlossen, wodurch die Notsteuerungseinrichtung 18 in Betrieb gesetzt wird. Bei Schliessen des Notfallkontaktes 20a wird die im Register 32a gespeicherte Adresse der Aufzugskabine A freigegeben und dem Dekodierer 33 zugeführt, worauf dessen der Aufzugskabine B zugeordneter Ausgang aktiviert wird. Mittels der dadurch eingeschalteten Signalisationseinrichtung 47b werden allenfalls anwesende Fahrgäste aufgefordert, die Aufzugskabine B sofort bzw. beim nächsten Halt zu verlassen, wobei noch vorhandene Fahrbefehle gelöscht und keine neuen mehr angenommen werden. Durch die Aktivierung des der Aufzugskabine B zugeordneten Dekodiererausganges und Schliessen des Notfallkontaktes 20a werden über die fünfte Gatteranordnung 45 die Leistungsschaltelemente 46a, 46b angesteuert und die Umschaltrelais 30a, 30b erregt, so dass die Aufzugskabinen A, B mittels der Kontakte 29 von den zugeordneten normalen Fahrsteuerungen abgeschaltet und die Fahrtrichtungsschütze 23, 24 der Aufzugskabine B über die weiteren Kontakte 31 an die Notsteuerungseinrichtung 18 angeschaltet werden.It may be assumed that the elevator car A was affected by an emergency as a result of a power cut in the control system and is blocked between two floors. In this case, when the alarm button in the elevator car A is actuated, an alarm is triggered in the porter's lodge of the building and the emergency con clock 20a closed, whereby the emergency control device 18 is put into operation. When the emergency contact 20a is closed, the address of the elevator car A stored in the register 32a is released and fed to the decoder 33, whereupon the output associated with the elevator car B is activated. By means of the signaling device 47b thereby switched on, any passengers present are asked to leave the elevator car B immediately or at the next stop, existing travel commands being deleted and no new ones being accepted. By activating the decoder output assigned to the elevator car B and closing the emergency contact 20a, the power switching elements 46a, 46b are actuated via the fifth gate arrangement 45 and the changeover relays 30a, 30b are excited, so that the elevator cars A, B by means of the contacts 29 from the assigned normal travel controls switched off and the direction of travel contactors 23, 24 of the elevator car B are connected to the emergency control device 18 via the further contacts 31.

Mit der Aktivierung des der Aufzugskabine B zugeordneten Dekodiererausganges und dem Schliessen des Notfallkontaktes 20a werden auch die in den weiteren Registern 34a, 34b enthaltenen Positionen der Aufzugskabinen A, B freigegeben und dem Komparator 35 zugeführt. Es möge nun angenommen sein, dass sich die für die Notfahrt ausgewählte Aufzugskabine B unterhalb der vom Notfall betroffenen Aufzugskabine A befindet. In diesem Falle wird nach dem Vergleich der beiden Positionen der der Aufwärtsrichtung zugeordnete Ausgang ub des Komparators 35 aktiviert. Da der Notfallkontakt 20a geschlossen ist, so wird nach Eintreffen eines Nullastsignales von der Aufzugskabine B über die erste und vierte Gatteranordnung 37, 40 das Leistungsschaltelement 41 angesteuert und bei geschlossenen Sicherheitskreiskontakten 27 das der Aufwärtsrichtung zugeordnete Fahrtrichtungsschütz 23 der Aufzugskabine B erregt. Die Aufzugskabine B setzt sich daher nach oben in Bewegung, wobei dem Antrieb mit der Umschaltung auf Notbetrieb auf nicht weiter beschriebene Weise eine kleine Fahrgeschwindigkeit vorgegeben wird. Erreicht die Aufzugskabine B das Niveau der blockierten Aufzugskabine A, so wird der Magnetschalter 16.1 betätigt. Das damit erzeugte Signal wirkt sich bei geschlossenem Notfallkontakt 20a derart aus, dass die Steuerspannung des Leistungsschaltelementes 41 über die vierte Gatteranordnung 40 abgeschaltet wird, das Fahrtrichtungsschütz 23 abfällt und die Aufzugskabine B anhält.With the activation of the decoder output assigned to the elevator car B and the closing of the emergency contact 20a, the positions of the elevator cars A, B contained in the further registers 34a, 34b are also released and fed to the comparator 35. It may now be assumed that the elevator car B selected for the emergency journey is located below the elevator car A affected by the emergency. In this case, after the comparison of the two positions, the output ub of the comparator 35 assigned to the upward direction is activated. Since the emergency contact 20a is closed, after the arrival of a zero load signal from the elevator car B, the power switching element 41 is actuated via the first and fourth gate arrangement 37, 40, and the closed directional contactor 23 of the elevator car B is excited when the safety circuit contacts 27 are closed. The elevator car B therefore starts to move upwards, the drive being given a low driving speed by switching to emergency operation in a manner not described further. When the elevator car B reaches the level of the blocked elevator car A, the magnetic switch 16.1 is actuated. The signal generated in this way has an effect when the emergency contact 20a is closed in such a way that the control voltage of the power switching element 41 is switched off via the fourth gate arrangement 40, the directional contactor 23 drops out and the elevator car B stops.

Nach dem Anhalten der Aufzugskabine B neben der blockierten Aufzugskabine A werden die Türen 14 der Übergangseinrichtungen 13 entriegelt und geöffnet. Gleichzeitig werden die Übergangseinrichtungen beleuchtet und die in der Aufzugskabine A befindlichen Fahrgäste durch optische und/oder akustische Signalisation aufgefordert, in die Aufzugskabine B umzusteigen. Danach wird durch geeignete Einrichtungen, beispielsweise Fotozellen, geprüft, ob sich noch Personen in den Übergangseinrichtungen 13 befinden. Ist das nicht der Fall, so werden die Türen 14 geschlossen und verriegelt sowie die Beleuchtung in den Übergangseinrichtungen 13 ausgeschaltet. Danach wird durch Eingabe eines Kabinenrufes das Signal Reset b erzeugt, wodurch über die fünfte Gatteranordnung 45 die Steuerspannung der Leistungsschaltelemente 46a, 46b abgeschaltet wird und die Umschaltrelais 30a, 30b abfallen, so dass die Aufzugskabinen A, B über die Kontakte 29 an die zugeordneten normalen Fahrsteuerungen geschaltet und die Fahrtrichtungsschütze 23, 24 der Aufzugskabine B mittels der weiteren Kontakte 31 von der Notsteuerungseinrichtung 18 abgeschaltet werden.After the elevator car B has stopped next to the blocked elevator car A, the doors 14 of the transition devices 13 are unlocked and opened. At the same time, the transition facilities are illuminated and the passengers in elevator car A are asked by optical and / or acoustic signaling to change to elevator car B. Then it is checked by suitable devices, for example photocells, whether there are still people in the transition devices 13. If this is not the case, the doors 14 are closed and locked and the lighting in the transition devices 13 is switched off. Then the signal Reset b is generated by entering a car call, whereby the control voltage of the power switching elements 46a, 46b is switched off via the fifth gate arrangement 45 and the changeover relays 30a, 30b drop, so that the elevator cars A, B via the contacts 29 to the assigned normal ones Travel controls are switched and the travel direction protection devices 23, 24 of the elevator car B are switched off by the emergency control device 18 by means of the further contacts 31.
