Definitions
- the invention relates to a braking device of an elevator car which brakes the elevator car at least when an inadmissibly high speed of the elevator car occurs.
- Out JP06092568 is such a braking device in which a speed limiter with a pulley via a speed limiter rope activates a brake unit on an elevator car.
- the speed governor rope circulates in the form of a closed loop, on the one hand, the pulley of the speed limiter arranged in the upper area of the car travel and, on the other hand, a cable deflection pulley present in the lower area of the car travel, one strand of the cable loop being coupled to an actuating element of the brake unit attached to the elevator car and thus to the elevator car is.
- the lower Seilumlenktech is arranged vertically movable and loaded in the downward direction by a weight so that the cable loop is stretched by the lower SeilumlenkMIC.
- a monitoring device with a detector monitors the position of this lower Seilumlenkusion to influence the elevator control in case of breakage or excessive elongation of theklasbe bayeauseils.
- the invention has for its object to provide a braking device of the type described above, which does not have the disadvantages of the cited as prior art device.
- a braking device for elevator cars is to be created in which, after a failure of the coupling between the speed governor cable and the brake unit of the elevator car, the elevator system does not remain in operation in a safety-related impermissible state.
- the advantage achieved by the invention is essentially to be seen in the fact that the reliability of the elevator system is increased by an operating condition is avoided in a failure of the coupling (operative connection) between the traction means and the elevator car or the brake unit of the elevator car, in which the elevator car people are transported, although the prescribed fuse through the braking device is no longer functional.
- the traction means of the braking device forms a Switzerlandstoffumlenkusionn circumferential closed loop, both ends of the traction means are fixed to a coupling element which simultaneously couples the traction means with the actuating element of the brake unit.
- the coupling element has a weight that is sufficient in the case of failure of the coupling between the traction means and the elevator car to move the traction means together with the Switzerlandstoffumlenkimin in motion, so that the coupling element drops.
- the monitoring device comprises a mounted in the lower Switzerlandstoffumlenkus detector which detects the coupling element, if this after a failure of the coupling between the traction means and the brake unit or the elevator car to the level of the detector has dropped.
- the monitoring device comprises a detector mounted on the elevator car, which detects in normal operation whether the coupling element is in its normal position relative to the elevator car located, and signals a failure of the coupling between the traction means and the elevator car as soon as he no longer recognizes the coupling element.
- the detector is a switch with galvanic contacts, which detects the presence of the coupling element by means of a mechanical probe element.
- a reliable and easy to install braking device is achieved with a detector comprising a sensor that detects the presence of the coupling element without contact.
- a detector comprising a sensor that detects the presence of the coupling element without contact.
- inductive sensors, capacitive sensors or light sensors are used for this purpose.
- the braking device according to the invention is designed such that the detector of the monitoring device is connected to an elevator control, which interrupts the operation of the elevator in the event of a detected failure of the coupling between the traction means and the brake unit or the elevator car.
- the elevator control is designed so that it interrupts the operation of the elevator after the detected failure of said coupling only when the elevator car has reached a floor. This avoids that passengers unnecessarily remain trapped in the elevator car and need to be evacuated with outside help.
- the attached to the elevator car 5 brake units 15 may be designed as a conventional elevator safety brakes.
- brake wedges or eccentric discs are brought into frictional contact with the car guide rails 4 via an actuating lever 16 and a - not shown here - mechanical system of levers, whereupon the brake wedges or the eccentric discs due to the existing between them and the car guide rails relative movement and the friction effect in a position be brought in which they themselves or an intermediate brake body are pressed so strong against the car guide rails that the elevator car is braked.
- the brake units 15 may, for example, also contain hydraulically actuated brake pistons, which press the brake plates against the car guide rail and thereby brake the elevator car.
- the actuating lever 16 acts on valves that control the pressurization of the brake piston and thus the pressing of the brake plates against the guide rails.
- these can slow down the travel of the elevator car in two or only in one direction of travel.
- An activation system activates the brake units 15 in the event of an impermissibly high speed - hereinafter referred to as overspeed - or in other situations recognized by the elevator control 30, which require immediate and safe braking of the elevator car.
- the activation system comprises a traction means 17 with two Anlagenstofftrumen extending parallel to the direction of travel of the elevator car, the traction means at least one upper Werstoffumlenkharimen 18 and a lower Werstoffumlenkusion 19 circulates and is connected at its two ends with a coupling element 23. This coupling element is coupled to the actuating lever 16 of the attached to the elevator car 5 brake unit 15 which is held in normal operation by a centering device 25 in its normal position.
- a blocking device 20 which blocks the traction means when detected overspeed of the traction means 17 and the elevator car, or adjacent, generated by the elevator control 30 blocking signal, which depending on the embodiment of the blocking device blocking by direct braking of the traction means 17 or by blocking the upper Switzerlandstoffumlenkhari 18 can be done.
- a pulling means 17 for the braking device for example, wire ropes, flat belts, toothed belts or link chains of all kinds are used.
- the coupling element 23 of the traction mechanism 21 sinks with the strand of the traction means fixed to it in the direction of the lower traction sheave 19.
- the coupling element 23 is designed sufficiently heavy for this purpose, so that its weight can move the traction means and the two Werschumlenkharin 18, 19 despite friction losses in motion.
- This situation is in the lowest part of the Fig. 1 shown where the detector 27 shown as an electrical switch with a mechanical probe element 27.1 and the sunken coupling element 23 shown in dashed lines is.
- the detector 27 signals the presence of the coupling element in its sunken position and thus the failure of said coupling between the coupling element 23 of the traction mechanism 21 and the elevator car 5 to the elevator control 30, which shuts down the elevator system, advantageously as soon as the elevator car has reached a floor.
- Fig. 2 shows a second embodiment of the inventive braking device 2, in which the position of the coupling element 23 is monitored with respect to the elevator car 5 by a detector connected to the car 28.
- a detector is used which detects the coupling element without contact, ie, which contains, for example, an inductively or capacitively operating sensor or an infrared light sensor.
- the detector 28 signals the failure of said coupling to the elevator control, which stops the elevator system, preferably only in this embodiment of the braking device when the elevator car has reached a floor. It makes sense to alert the service organization responsible for the elevator installation at the same time.
- Fig. 2 is already related to Fig. 1 mentioned centering device 25 particularly well recognizable, the operating lever 16 of the mounted on the elevator car 5 brake unit 15 is fixed in its normal position during normal operation of the elevator system to ensure that a strand of the circulating traction means 17 in the Normal operation moves synchronously with the elevator car up and down.
- the centering of the actuating lever 16 in its normal position is realized in that a guided in a bore ball is pressed by a compression spring into a notch of a disc which is rotatable in solidarity with the actuating lever 16 about a common lever axis 26.

Description
Die Erfindung betrifft eine Bremseinrichtung einer Aufzugskabine, die mindestens beim Auftreten einer unzulässig hohen Geschwindigkeit der Aufzugskabine die Aufzugskabine bremst.The invention relates to a braking device of an elevator car which brakes the elevator car at least when an inadmissibly high speed of the elevator car occurs.
Aus
Beim genannten Stand der Technik werden zwar ein Bruch oder eine übermässige Längung des Geschwindigkeitsbegrenzerseils durch den Detektor erkannt und gegebenenfalls entsprechende Sicherheitsmassnahmen eingeleitet. Ein während des Aufzugsbetriebs auftretender Ausfall der Kopplung zwischen dem Geschwindigkeitsbegrenzerseil und der Aufzugskabine wird jedoch durch die Überwachungseinrichtung nicht erkannt. Dies hat zur Folge, dass die Aufzugsanlage bei Ausfall der genannten Kopplung weiterhin in Betrieb bleibt, obwohl die für die Sicherheit der Aufzugspassagiere äusserst wichtige Bremseinrichtung an der Aufzugskabine nicht funktioniert.In the cited prior art, although a break or excessive elongation of the speed governor rope are detected by the detector and, if appropriate, appropriate safety measures are initiated. A failure of the coupling between the speed governor cable and the elevator car occurring during the elevator operation becomes however, not recognized by the monitoring device. This has the consequence that the elevator system remains in operation in case of failure of said coupling, although the extremely important for the safety of the elevator passengers braking device on the elevator car does not work.
Mögliche Ursachen für einen solchen Ausfall der Kopplung zwischen dem Geschwindigkeitsbegrenzerseil und der Bremseinheit bzw. der Aufzugskabine sind beispielsweise ein herausgefallener oder gebrochener Verbindungsbolzen, ein gebrochener Betätigungshebel (Betätigungselement) der Bremseinheit oder eine gebrochene Betätigungswelle, über welche der Betätigungshebel mit der Bremseinheit bzw. mit der Aufzugskabine verbunden ist.Possible causes for such a failure of the coupling between the speed governor cable and the brake unit or the elevator car, for example, a fallen or broken connecting pin, a broken operating lever (actuator) of the brake unit or a broken actuating shaft, via which the actuating lever to the brake unit or with the Elevator car is connected.
Der Erfindung liegt die Aufgabe zugrunde, eine Bremseinrichtung der vorstehend beschriebenen Art vorzuschlagen, die die Nachteile der als Stand der Technik zitierten Einrichtung nicht aufweist. Insbesondere soll also eine Bremseinrichtung für Aufzugskabinen geschaffen werden, bei welcher nach einem Ausfall der Kopplung zwischen dem Geschwindigkeitsbegrenzerseil und der Bremseinheit der Aufzugskabine die Aufzugsanlage nicht in einem sicherheitstechnisch unzulässigen Zustand weiter in Betrieb bleibt.The invention has for its object to provide a braking device of the type described above, which does not have the disadvantages of the cited as prior art device. In particular, therefore, a braking device for elevator cars is to be created in which, after a failure of the coupling between the speed governor cable and the brake unit of the elevator car, the elevator system does not remain in operation in a safety-related impermissible state.
Erfindungsgemäss wird die Aufgabe durch eine Bremseinrichtung für eine Aufzugskabine sowie durch eine Aufzugsanlage mit der genannten Bremseinrichtung gelöst, wobei die Bremseinrichtung folgende Merkmale aufweist:
- umfasst mindestens eine an der Aufzugskabine angebrachte Bremseinheit mit einem Betätigungselement,
- umfasst mindestens zwei Zugmittelumlenkscheiben, von denen je eine im Bereich des oberen bzw. des unteren Endes des Kabinenfahrwegs installiert ist,
- umfasst ein flexibles Zugmittel, das die Zugmittelumlenkscheiben umläuft, wobei mindestens ein Trum des Zugmittels sich parallel zum Fahrweg der Aufzugskabine erstreckt, mit dem Betätigungselement der Bremseinheit und somit mit der Aufzugskabine gekoppelt ist und sich im Normalbetrieb synchron mit der Aufzugskabine bewegt,
- umfasst eine Blockiervorrichtung, die mindestens bei Übergeschwindigkeit der Aufzugskabine das Zugmittel bremst, wodurch dieses über das Betätigungselement die Bremseinheit aktiviert,
- umfasst eine Überwachungseinrichtung, die einen Ausfall der Kopplung zwischen dem Zugmittel und der Aufzugskabine detektiert.
- comprises at least one brake unit attached to the elevator car with an actuating element,
- comprises at least two Zugmittelumlenkscheiben, each of which is installed in the region of the upper and the lower end of the cabin travel,
- comprises a flexible traction means, which rotates the Zugmittelumlenkscheiben, wherein at least one strand of the traction means extends parallel to the travel path of the elevator car, is coupled to the actuating element of the brake unit and thus to the elevator car and moves in synchronous operation with the elevator car during normal operation,
- comprises a blocking device which brakes the traction means at least in the case of an overspeed of the elevator car, thereby activating the brake unit via the actuating element,
- includes a monitoring device that detects a failure of the coupling between the traction means and the elevator car.
Der durch die Erfindung erreichte Vorteil ist im Wesentlichen darin zu sehen, dass die Betriebssicherheit der Aufzugsanlage erhöht wird, indem bei einem Ausfall der Kopplung (Wirkverbindung) zwischen dem Zugmittel und der Aufzugskabine bzw. der Bremseinheit der Aufzugskabine ein Betriebszustand vermieden wird, in welchem mit der Aufzugskabine Personen transportiert werden, obwohl die vorgeschriebene Sicherung durch die Bremseinrichtung nicht mehr funktionsfähig ist.The advantage achieved by the invention is essentially to be seen in the fact that the reliability of the elevator system is increased by an operating condition is avoided in a failure of the coupling (operative connection) between the traction means and the elevator car or the brake unit of the elevator car, in which the elevator car people are transported, although the prescribed fuse through the braking device is no longer functional.
Vorteilhafte Ausgestaltungen und Weiterbildungen des Erfindungsgegenstands gehen aus den Unteransprüchen hervor und sind im Folgenden beschrieben:Advantageous embodiments and further developments of the subject invention will become apparent from the dependent claims and are described below:
Gemäss einer bevorzugten Ausführungsform der Erfindung bildet das Zugmittel der Bremseinrichtung eine die Zugmittelumlenkscheiben umlaufende geschlossene Schleife, wobei beide Enden des Zugmittels an einem Kopplungselement fixiert sind, welches gleichzeitig das Zugmittel mit dem Betätigungselement der Bremseinheit koppelt. Die Kombination der Verbindung der Zugmittelenden und der genannten Kopplung in einem einzigen Element hat die Vorteile, dass mit derselben Komponente zwei Funktionen erfüllt werden, dass das Gewicht in einer einzigen Komponente konzentriert ist, und dass damit grösstmögliche Freiheit für die Anordnung der Zugmittelumlenkscheiben erreicht wird.According to a preferred embodiment of the invention, the traction means of the braking device forms a Zugmittelumlenkscheiben circumferential closed loop, both ends of the traction means are fixed to a coupling element which simultaneously couples the traction means with the actuating element of the brake unit. The combination of the connection of the traction means ends and the said coupling in a single element has the advantages that with the same component two functions are fulfilled, that the weight is concentrated in a single component, and that thus the greatest possible freedom for the arrangement of Zugmittelumlenkscheiben is achieved.
Zweckmässigerweise hat das Kopplungselement ein Gewicht, das im Falle des Ausfalls der Kopplung zwischen dem Zugmittel und der Aufzugskabine ausreicht, das Zugmittel mitsamt den Zugmittelumlenkscheiben in Bewegung zu versetzen, so dass das Kopplungselement absinkt.Conveniently, the coupling element has a weight that is sufficient in the case of failure of the coupling between the traction means and the elevator car to move the traction means together with the Zugmittelumlenkscheiben in motion, so that the coupling element drops.
Eine besonders einfache und kostengünstige Ausführungsform der Erfindung wird dadurch erreicht, dass die Überwachungseinrichtung einen im Bereich der unteren Zugmittelumlenkscheibe angebrachten Detektor umfasst, der das Kopplungselement detektiert, wenn dieses nach einem Ausfall der Kopplung zwischen dem Zugmittel und der Bremseinheit bzw. der Aufzugskabine auf das Niveau des Detektors abgesunken ist.A particularly simple and inexpensive embodiment of the invention is achieved in that the monitoring device comprises a mounted in the lower Zugmittelumlenkscheibe detector which detects the coupling element, if this after a failure of the coupling between the traction means and the brake unit or the elevator car to the level of the detector has dropped.
Bei einer besonders bevorzugten und funktionssicheren Ausführungsform der Erfindung umfasst die Überwachungseinrichtung einen an der Aufzugskabine angebrachten Detektor, der im Normalbetrieb detektiert, ob das Kopplungselement sich in seiner in Bezug auf die Aufzugskabine normalen Lage befindet, und der einen Ausfall der Kopplung zwischen dem Zugmittel und der Aufzugskabine signalisiert, sobald er das Kopplungselement nicht mehr erkennt.In a particularly preferred and functionally reliable embodiment of the invention, the monitoring device comprises a detector mounted on the elevator car, which detects in normal operation whether the coupling element is in its normal position relative to the elevator car located, and signals a failure of the coupling between the traction means and the elevator car as soon as he no longer recognizes the coupling element.
Bei einer besonders kostengünstigen Ausgestaltung der erfindungsgemässen Bremseinrichtung ist der Detektor ein Schalter mit galvanischen Kontakten, der die Anwesenheit des Kopplungselements mit Hilfe eines mechanischen Tastelements detektiert.In a particularly cost-effective embodiment of the inventive braking device, the detector is a switch with galvanic contacts, which detects the presence of the coupling element by means of a mechanical probe element.
Eine zuverlässige und einfach zu installierende Bremseinrichtung wird mit einem Detektor erreicht, der einen Sensor umfasst, der die Anwesenheit des Kopplungselements berührungsfrei detektiert. Vorteilhafterweise werden dafür Induktiv-Sensoren, Kapazitiv-Sensoren oder Lichtsensoren verwendet.A reliable and easy to install braking device is achieved with a detector comprising a sensor that detects the presence of the coupling element without contact. Advantageously, inductive sensors, capacitive sensors or light sensors are used for this purpose.
Zweckmässigerweise ist die erfindungsgemässe Bremseinrichtung so ausgestaltet, dass der Detektor der Überwachungseinrichtung mit einer Aufzugssteuerung in Verbindung steht, welche im Fall eines detektierten Ausfalls der Kopplung zwischen dem Zugmittel und der Bremseinheit bzw. der Aufzugskabine den Betrieb des Aufzugs unterbricht.Conveniently, the braking device according to the invention is designed such that the detector of the monitoring device is connected to an elevator control, which interrupts the operation of the elevator in the event of a detected failure of the coupling between the traction means and the brake unit or the elevator car.
Bei einer bevorzugten Ausgestaltung der Erfindung ist die Aufzugssteuerung so konzipiert, dass sie nach detektiertem Ausfall der genannten Kopplung den Betrieb des Aufzugs erst unterbricht, wenn die Aufzugskabine ein Stockwerk erreicht hat. Dadurch wird vermieden, dass Passagiere unnötigerweise in der Aufzugskabine eingeschlossen bleiben und mit fremder Hilfe evakuiert werden müssen.In a preferred embodiment of the invention, the elevator control is designed so that it interrupts the operation of the elevator after the detected failure of said coupling only when the elevator car has reached a floor. This avoids that passengers unnecessarily remain trapped in the elevator car and need to be evacuated with outside help.

Im Folgenden werden die Bremseinrichtung und ihre Funktionsweise detaillierter beschrieben.In the following, the braking device and its operation will be described in more detail.
Die an der Aufzugskabine 5 angebrachten Bremseinheiten 15 können als übliche Aufzugs-Fangbremsen ausgeführt sein. Bei solchen werden beispielsweise Bremskeile oder Exzenterscheiben über einen Betätigungshebel 16 und ein - hier nicht dargestelltes - mechanisches Hebelsystem mit den Kabinenführungsschienen 4 in Reibkontakt gebracht, worauf die Bremskeile bzw. die Exzenterscheiben infolge der zwischen ihnen und den Kabinenführungsschienen vorhandenen Relativbewegung und der Reibwirkung in eine Stellung gebracht werden, in welcher sie selbst oder ein dazwischen liegender Bremskörper so stark gegen die Kabinenführungsschienen gepresst werden, dass die Aufzugskabine gebremst wird.The attached to the
Die Bremseinheiten 15 können beispielsweise auch hydraulisch betätigte Bremskolben enthalten, die Bremsplatten gegen die Kabinenführungsschiene pressen und dadurch die Aufzugskabine bremsen. Vorzugsweise wirkt der Betätigungshebel 16 dabei auf Ventile, die die Beaufschlagung der Bremskolben mit Druckflüssigkeit und damit das Anpressen der Bremsplatten gegen die Führungsschienen steuern.The
Je nach Ausführungsart der Bremseinheiten können diese die Fahrt der Aufzugskabine in beiden oder nur in einer Fahrrichtung bremsen.Depending on the embodiment of the brake units, these can slow down the travel of the elevator car in two or only in one direction of travel.
Ein Aktivierungssystem aktiviert die Bremseinheiten 15 im Fall einer unzulässig hohen Geschwindigkeit - im Folgenden als Übergeschwindigkeit bezeichnet - oder auch in andern von der Aufzugssteuerung 30 erkannten Situationen, die eine sofortige und sichere Bremsung der Aufzugskabine erfordern. Das Aktivierungssystem umfasst ein Zugmittel 17 mit zwei sich parallel zur Fahrrichtung der Aufzugskabine erstreckenden Zugmitteltrumen, wobei das Zugmittel mindestens eine obere Zugmittelumlenkscheibe 18 und eine untere Zugmittelumlenkscheibe 19 umläuft und an seinen beiden Enden mit einem Kopplungselement 23 verbunden ist. Dieses Kopplungselement ist an den Betätigungshebel 16 der an der Aufzugskabine 5 angebrachten Bremseinheit 15 gekoppelt, der im Normalbetrieb durch eine Zentriervorrichtung 25 ausrastbar in seiner Normallage gehalten wird. Dadurch wird erreicht, dass ein Trum des umlaufenden Zugmittels 17 sich im Normalbetrieb synchron mit der Aufzugskabine auf und ab bewegt. Im Bereich der oberen Zugmittelumlenkscheibe 18 ist eine Blockiervorrichtung 20 vorhanden, die bei detektierter Übergeschwindigkeit des Zugmittels 17 und der Aufzugskabine, oder bei anliegendem, von der Aufzugssteuerung 30 erzeugtem Blockiersignal das Zugmittel blockiert, wobei je nach Ausführungsart der Blockiervorrichtung die Blockierung durch direkte Bremsung des Zugmittels 17 oder durch Blockierung der oberen Zugmittelumlenkscheibe 18 erfolgen kann.An activation system activates the

Beim Auftreten einer unzulässig hohen Geschwindigkeit - im Folgenden als Übergeschwindigkeit bezeichnet - oder auch bei andern von der Aufzugssteuerung erkannten Situationen, die eine sofortige und sichere Bremsung der Aufzugskabine 5 erfordern, wird das Zugmittel 17 durch die Blockiervorrichtung 20 blockiert, was zur Folge hat, dass das Kopplungselement 23 den Betätigungshebel 16 der Bremseinheiten 15 aus seiner durch die Zentriervorrichtung 25 ausrastbar zentrierten Lage auslenkt und damit die Bremseinheiten aktiviert.Upon the occurrence of an impermissibly high speed - hereinafter referred to as overspeed - or in other situations recognized by the elevator control, which require immediate and safe braking of the
Im Fall des vorstehend beschriebenen Ausfalls der Kopplung zwischen dem Kopplungselement 23 des Zugmittels 21 und der Aufzugskabine 5 bzw. den an dieser befestigten Bremseinheiten 15, sinkt das Kopplungselement mit dem an ihm fixierten Trum des Zugmittels in Richtung auf die untere Zugmittelumlenkscheibe 19 ab. Das Kopplungselement 23 ist zu diesem Zweck ausreichend schwer ausgeführt, so dass seine Gewichtskraft das Zugmittel und die beiden Zugmittelumlenkscheiben 18, 19 trotz Reibungsverlusten in Bewegung versetzen kann.In the case of the above-described failure of the coupling between the
