Description

Die Erfindung betrifft eine Einrichtung zur Stillsetzung einer Aufzugsanlage, bestehend aus einem, die Geschwindigkeit einer mittels Tragseil mit einem Gegengewicht verbundenen Aufzugskabine überwachenden Geschwindigkeitsbegrenzer, wobei die Bewegung der Aufzugskabine bzw. des Gegengewichtes mittels eines Begrenzerseiles auf den Geschwindigkeitsbegrenzer übertragen wird, der die Stillsetzung der Aufzugsanlage bei Übergeschwindigkeit auslöst.The invention relates to a device for decommissioning an elevator system consisting of one that Speed one with a carrying rope Monitor counterweight connected elevator car Speed limiter, the movement of the Elevator car or the counterweight by means of a Limiter rope on the speed limiter is transferred, the shutdown of the elevator system Triggers overspeed.

Aus der Patentschrift DE 36 15 270 C2 ist ein Geschwindigkeitsbegrenzer bekannt geworden, der die Fahrgeschwindigkeit einer Aufzugskabine überwacht. Die Aufzugskabine treibt über ein Drahtseil eine Seilscheibe mit integriertem Sperrkranz an. Ein Nockenrad versetzt einen Pendelhebel mit einer Pendelnase in Pendelbewegungen. Auf dem Pendelhebel ist ein Betätigungshebel drehbar gelagert, der mittels einer Rückhalteeinrichtung gegenüber dem Pendelhebel in Ruhelage gehalten wird. Das obere Ende des Betätigungshebels ist als Betätigungsbügel ausgebildet, am unteren Ende sitzt die gegenüber einer Pendelnase vorstehende Auslösenase. Beide Nasen liegen immer dann zwischen zwei Speerkranzzähnen, wenn die Pendelrolle auf einer Nocke steht. Wenn die Pendelrolle zwischen zwei Nocken steht, werden beide Nasen aus der Bahne der Sperrkranzzähne gehoben. Dadurch bewegen sich die Sperrkranzzähne ohne Wirkung an den Nasen vorbei. Bei Übergeschwindigkeit hebt die Pendelrolle vom Nockenrad ab. Die Auslösenase bleibt in der Sperrkranzbahn eingetaucht. Ein Sperrkranzzahn greift an der Auslösenase an und lenkt den Betätigungshebel aus. Dadurch schaltet der Betätigungsbügel über einen Schalter den Antrieb ab. Bei weiterem Anstieg der Kabinegeschwindigkeit taucht die Pendelnase in die Sperrkranzbahn ein und blockiert über die Sperrkranzzähne die Seilscheibe. Durch die Friktion in der Seilrille wird die Kraft zur Auslösung einer Fangvorrichtung aufgebaut.From the patent DE 36 15 270 C2 is a Speed limiter has become known which the Driving speed of an elevator car monitored.

In den Fig. 1 bis 4 ist mit 1 eine in einem nicht dargestellten Aufzugsschacht verfahrbare Aufzugskabine bezeichnet, welche mittels eines über eine Treibscheibe 2 geführtes Tragseil 3 mit einem Gegengewicht 4 verbunden ist. Zur Überwachung der Geschwindigkeit der Aufzugskabine 1 bzw. des Gegengewichtes 4 ist beispielsweise ein auf dem Pendelhebelprinzip arbeitender Geschwindigkeitsbegrenzer 5 vorgesehen, wobei die Bewegung der Aufzugskabine 1 bzw. des Gegengewichtes 4 mittels eines Begrenzerseiles 6 auf den Geschwindigkeitsbegrenzer 5 übertragen wird. Beispielsweise auf dem Fliehkraftprinzip oder auf dem Massenträgheitsprinzip arbeitende Begrenzer können auch für die Geschwindigkeitsüberwachung verwendet werden. Das Begrenzerseil 6 erstreckt sich über die gesamte Schachthöhe und wird am unteren Schachtende mittels einer Umlenkrolle 7 umgelenkt und gespannt sowie am oberen Schachtende über eine Seilscheibe des Geschwindigkeitsbegrenzers 5 geführt. 1 to 4, 1 is not one in one shown elevator shaft movable elevator car referred to, which by means of a traction sheave 2 guided carrying rope 3 connected to a counterweight 4 is. To monitor the speed of the elevator car 1 or the counterweight 4 is, for example, one on the Pendulum lever principle working speed limiter 5 provided, the movement of the elevator car 1 and the Counterweight 4 by means of a governor rope 6 on the Speed limiter 5 is transmitted. For example on the centrifugal force principle or on the The principle of inertia can also work for speed monitoring can be used. The Limiter rope 6 extends over the entire shaft height and is at the bottom of the shaft by means of a pulley 7 deflected and tensioned as well as at the top of the shaft a pulley of the speed limiter 5 out.

Die Enden des Begrenzerseiles 6 sind an einem drehbar an der Aufzugskabine 1 gelagerten ersten Auslösehebel 8 festgemacht, der im Notfall eine an der Aufzugskabine 1 angeordnete Fangvorrichtung 9 betätigt. Nach dem Lösen der Aufzugskabine 1 aus dem Fang setzt eine Rückstellfeder 10 den ersten Auslösehebel 8 und die Fangvorrichtung 9 zurück. Am Gegengewicht 4 ist ein Ausleger 11 angeordnet, durch den das Begrenzerseil 6 geführt ist. Nahe beim Ausleger 11 trägt ein fest mit dem Begrenzerseil 6 verbundener Federsockel 12 eine Ausgleichsfeder 13, die mit ihrer Federkraft gegen den Ausleger 11 drückt. Ausleger 11, Federsockel 12 und Ausgleichsfeder 13 bilden eine elastische Seilkupplung, die unterschiedliche Seildehnungen zwischen Tragseil 3 und Begrenzerseil 6 aufnehmen kann. Eine Auslösemechanik 14 des Geschwindigkeitsbegrenzers 5 betätigt bei Übergeschwindigkeit der Aufzugskabine 1 in Aufwärtsrichtung eine Seilbremse 15.The ends of the limiter rope 6 are rotatable on one the first release lever 8 mounted on the elevator car 1 moored in an emergency in the elevator car 1 arranged safety gear 9 actuated. After loosening the An elevator car 1 from the catch sets a return spring 10 the first release lever 8 and the safety device 9 back. On the counterweight 4, a boom 11 is arranged through which the governor rope 6 is guided. Near boom 11 carries a firmly connected to the governor rope 6 Spring base 12 a compensating spring 13, with its Presses spring force against the boom 11. Outrigger 11, Spring base 12 and compensating spring 13 form one elastic rope coupling, the different rope expansions can accommodate between suspension cable 3 and 6 limiter rope.

Bei Übergeschwindigkeit der Aufzugskabine 1 in Aufwärtsrichtung wird der Geschwindigkeitsbegrenzer 5 nicht wie bei Übergeschwindigkeit in Abwärtsrichtung blockiert, sondern die Seilbremse 15 mittels der Auslösemechanik 14 betätigt. Die Seilbremse 15 muss mindestens die unausgeglichenen Kräfte an der Treibscheibe 2 kompensieren, um eine weitere Beschleunigung der aufwärts fahrenden Aufzugskabine 1 zu verhindern. Bei einer höher liegenden Bremskraft wird das System entsprechend dem Anlageträgheitsmoment verzögert. Die von der Seilbremse 15 aufzubringende Bremskraft muss mindestens so gross sein, wie die maximale Seilkraftdifferenz an der Treibscheibe 2.If the elevator car is too fast 1 in The speed limiter 5 does not become upward as blocked at overspeed in the downward direction, but the rope brake 15 by means of the trigger mechanism 14 operated. The rope brake 15 must be at least compensate for unbalanced forces on the traction sheave 2, to further accelerate the ascending To prevent elevator car 1. With a higher one The system will brake accordingly System moment of inertia delayed. The from the rope brake 15 braking force to be applied must be at least as large like the maximum rope force difference on the traction sheave 2.

Fig. 2 zeigt Einzelheiten des Geschwindigkeitsbegrenzers 5, des Auslösemechanismus 14 und der Seilbremse 15. Das Begrenzerseil 6 ist über eine an einer ersten Achse 16 drehbar gelagerte Seilscheibe 17 mit einer Seilrille geführt. Die erste Achse 16 ist von einem Gehäuse 18 getragen. An der Seilscheibe 17 ist ein Sperrkranz 19 mit Sperrkranzähnen 20 und ein Nockenrad 21 mit Nocken 22 angeordnet. Das Gehäuse 18 trägt eine zweite Achse 23, an der ein Pendelhebel 24 mit einer Pendelrolle 25 drehbar gelagert ist. Bei Normalgeschwindigkeit folgt die Pendelrolle 25 der durch die Nocken 22 gebildeten Nockenbahn des Nockenrades 21. Bei Übergeschwindigkeit vermag die Pendelrolle 25 aufgrund der Trägheit des Pendelhebels 24 der Nockenbahn nicht mehr zu folgen. An dem der Pendelrolle 25 gegenüberliegenden Ende des Pendelhebels 24 ist eine erste Nase 26 angeordnet, die bei Normalgeschwindigkeit der Aufzugskabine 1 zwischen zwei Sperrkranzzähne 20 eintaucht, wenn die Pendelrolle 25 auf einer Nocke 22 steht und die aus der Bahn der Sperrkranzzähne 20 gehoben wird, wenn die Pendelrolle 25 zwischen zwei Nocken 22 steht. Bei Übergeschwindigkeit der Aufzugskabine 1 in Abwärtsrichtung bleibt die erste Nase 26 zwischen zwei Sperrkranzzähnen 20 stehen, wobei die rechte Flanke des nachfolgenden Sperrkranzzahnes 20 an der ersten Nase 26 ansteht und den Sperrkranz 19 und somit die Seilscheibe 17 blockiert. Durch die Relativbewegung der Aufzugskabine 1 gegenüber dem blockierten Begrenzerseil 6 wird mittels des ersten Auslösehebels 8 die Fangvorrichtung 9 eingerückt und die Aufzugskabine 1 an den Führungsschienen festgesetzt.2 shows details of the speed limiter 5, the trigger mechanism 14 and the rope brake 15. Das Limiter rope 6 is connected to a first axis 16 rotatably mounted pulley 17 with a rope groove guided. The first axis 16 is from a housing 18 carried. On the sheave 17 is a locking ring 19 with Locking ring teeth 20 and a cam wheel 21 with cams 22 arranged. The housing 18 carries a second axis 23 of a pendulum lever 24 rotatable with a pendulum roller 25 is stored. This follows at normal speed Pendulum roller 25 formed by the cams 22 Cam track of the cam wheel 21. At overspeed the pendulum roller 25 due to the inertia of Pendulum lever 24 of the cam track no longer to follow. To the the pendulum roller 25 opposite end of the pendulum lever 24 a first nose 26 is arranged, which at Normal speed of the elevator car 1 between two Ratchet teeth 20 immersed when the pendulum roller 25 on a cam 22 stands and which from the path of Ratchet teeth 20 is raised when the pendulum roller 25 stands between two cams 22. If the speed is too high The elevator car 1 in the downward direction remains the first nose 26 stand between two ratchet teeth 20, the right one Flank of the subsequent ratchet tooth 20 on the first Nose 26 is pending and the locking ring 19 and thus the Pulley 17 blocked. Due to the relative movement of the Elevator car 1 opposite the blocked governor rope 6 is the safety device by means of the first release lever 8 9 indented and the elevator car 1 to the Guide rails fixed.

An dem der Pendelrolle 25 gegenüberliegenden Ende des Pendelhebels 24 ist ein Betätigungshebel 27 an einer dritten Achse 28 des Pendelhebels 24 drehbar angeordnet. Der Betätigungshebel 27 wird mittels einer Rückhalteeinrichtung, beispielsweise mittels eines Schnäppers relativ zum Pendelhebel 24 in einer Ruhelage gehalten. Eine zweite Nase 29 des Betätigungshebels 27 taucht bei Normalgeschwindigkeit der Aufzugskabine 1 zwischen zwei Sperrkranzzähne 20 ein, wenn die Pendelrolle 25 auf einer Nocke 22 steht und wird aus der Bahn der Sperrkranzzähne 20 gehoben wird, wenn die Pendelrolle 25 zwischen zwei Nocken 22 steht. Bei Übergeschwindigkeit der Aufzugskabine 1 in Aufwärtsrichtung bleibt die zweite Nase 29 zwischen zwei Sperrkranzzähnen 20 stehen, wobei die linke Flanke des nachfolgenden Sperrkranzzahnes 20 an der zweiten Nase 29 ansteht und den Betätigungshebel 27 in eine Rechtsdrehung versetzt. Der Sperrkranz 19 und somit die Seilscheibe 17 und das Begrenzerseil 6 bewegen sich weiter. Durch die Rechtsdrehung des Betätigungshebels 27 versetzt ein Betätigungsschenkel 30 des Betätigungshebels 27 einen zweiten Ausläsehebel 31 der Seilbremse 15 in eine Linksdrehung um eine vierte Achse 32 der Seilbremse 15, wobei mindestens eine mittels mindestens einer Druckfeder 33 verschiebbare Bremsbacke 34 freigesetzt wird. Die Bremsbacke 34 bewegt sich nach unten und wird mittels der Druckfeder 33 gegen mindestens eine am Gehäuse 18 angeordnete Gegenbacke 35 gepresst, wobei das zwischen den Backen 34, 35 laufende Begrenzerseil 6 abgebremst wird. Die auf das Begrenzerseil 6 ausgeübte Bremskraft bremst die Aufzugskabine 1 und das Gegengewicht 4 sanft ab und ist abhängig von der Federkraft der Druckfeder 33, der Oberfläche der Backen 34, 35 und von der Oberfläche des Begrenzerseiles 6. Die Abbremsung erfolgt via Begrenzerseil 6, Federsockel 12, Ausgleichsfeder 13 und Ausleger 11 auf das Gegengewicht 4.At the opposite end of the pendulum roller 25 Pendulum lever 24 is an operating lever 27 on one third axis 28 of the pendulum lever 24 rotatably arranged. The operating lever 27 is by means of a Restraint device, for example by means of a Schnäppers relative to the pendulum lever 24 in a rest position held. A second nose 29 of the actuating lever 27 dives at normal speed of elevator car 1 between two ratchet teeth 20 when the pendulum roller 25 stands on a cam 22 and becomes the web of Ratchet teeth 20 is raised when the pendulum roller 25 stands between two cams 22. If the speed is too high The second nose remains elevator car 1 in the upward direction 29 stand between two ratchet teeth 20, the left flank of the subsequent ratchet tooth 20 on the second nose 29 is present and the actuating lever 27 in a Right turn offset.
