Abstract

With this safety brake device, overspeeds of an elevator cabin or of a counterweight in the down direction are avoided. On its front side, a housing (1) has a recess (2) which extends over the entire housing height and on one end of which a brake plate (3) is arranged which has a free leg (4) plunging next to it. A trapezoidal stirrup (6) with a rectangular extension (7) projecting from the housing (1) is inserted into the part of the recess (2) adjoining the leg (4). On the guide-rail side, the stirrup (6) has a slotted link (9) running up at an angle and having a U-shaped cross-section. The two end faces of the slotted link (9) serve as rolling paths for roller spindles (12) arranged on a cylindrical catch roller (11). A camber in the form of an additional inclined control face (13) is provided in the lower part of the slotted link (9), with which camber the catch roller (11) is guided more quickly to the free leg (4). The recess (2) ends with an inclined wedge surface (14) on the side opposite the brake plate (3). The stirrup (6) bears on the inclined wedge surface (14). A longitudinal slot (15) running vertically through the stirrup (6) and deep into the extension (7) gives the stirrup (6) the necessary elasticity. <IMAGE>

Description

Die Erfindung betrifft eine Bremsfangvorrichtung mit in Wechselwirkung mit einem freien Schenkel einer Führungsschiene stehender Fangrolle im Keilspalt und Bremsplatte zum Abbremsen bis zum Stillstand einer Aufzugskabine oder eines Gegengewichts.The invention relates to a brake safety device in interaction with a free leg of a guide rail catching roller in the wedge gap and brake plate for braking until an elevator car or a counterweight comes to a standstill.

Aus der Patentschrift DE-A1-26 04 157 ist eine Bremsfangvorrichtung mit einem Führungskeil und einer Gegenbacke bekannt, die bei Normalbetrieb entlang einem freien Schenkel einer Führungsschiene geführt werden. Der Führungskeil ist am unteren Ende mittels einem Führungsbolzen drehbar gelagert und am oberen Ende von einem justierbaren Federpaket gehalten. Im Störfall wird eine Rollenhaiterung nach oben ausgelenkt. Dadurch wird eine Fangrolle über ein Auflager aus der Ruheposition entlang der Kante des Führungskeils nach oben bewegt. Mit dem Auftreffen der Fangrolle auf der Führungsschiene wird der Führungskeil nach rechts ausgeschwenkt und das Federpaket unter Spannung gesetzt. Die Aufwärtsbewegung der Fangrolle wird durch einen am oberen Ende des Fangkeils angeordneten Bremskeil begrenzt. Wenn die vom Federpaket ausgeübte Kraft einen vorherbestimmten Wert überschreitet, bewegt sich die gesamte Vorrichtung nach rechts und die Gegenbacke legt sich an die Führungsschiene an.From the patent specification DE-A1-26 04 157 a brake safety device with a guide wedge and a counter shoe is known, which are guided along a free leg of a guide rail during normal operation. The guide wedge is rotatably supported at the lower end by means of a guide pin and is held at the upper end by an adjustable spring assembly. In the event of a malfunction, a roller bracket is deflected upwards. As a result, a catch roller is moved upwards over the support from the rest position along the edge of the guide wedge. When the catching roller hits the guide rail, the guide wedge is swung out to the right and the spring assembly is put under tension. The upward movement of the catch roller is limited by a brake wedge arranged at the upper end of the catch wedge. When the force exerted by the spring assembly exceeds a predetermined value, the entire device moves to the right and the counter jaw rests on the guide rail.

Ein Nachteil der bekannten Einrichtung liegt im grossen mechanischen Aufbau des drehbar gelagerten Führungskeils und des am oberen Ende des Führungskeils angreifenden Federpakets. Ein weiterer Nachteil der bekannten Einrichtung besteht darin, dass vor Inbetriebnahme und nach einem Störfall ein zusätzlicher Aufwand an Justierarbeiten an Federpaket und Bremskeil unumgänglich ist.A disadvantage of the known device lies in the large mechanical structure of the rotatably mounted guide wedge and the spring assembly acting on the upper end of the guide wedge. Another disadvantage of the known device is that additional commissioning work on the spring assembly and the brake wedge is essential before start-up and after a malfunction.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtung zu vermeiden und eine Bremsfangvorrichtung so auszubilden, dass mit weniger Einzelteilen eine an unterschiedliche Gesamtgewichte von Aufzugskabine beziehungsweise Gegengewicht anpassbare Bremsfangverzögerung machbar ist.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of avoiding the disadvantages of the known device and of designing a brake safety device in such a way that a brake safety delay that can be adapted to different total weights of the elevator car or counterweight is feasible with fewer individual parts.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass durch den einfachen Aufbau der Einzelteile eine weitgehend automatisierte Fertigung der Bremsfangvorrichtung ermöglicht wird. Als weiterer Vorteil sind die einfachen Einstellarbeiten zur Anpassung der Bremsfangverzögerung an die unterschiedlichen Gesamtgewichte von Aufzugskabine und Gegengewicht anzusehen. Automatisierte Fertigung wie auch einfache Einstellarbeiten wirken sich positiv auf die Herstellungskosten der in grossen Stückzahlen gefertigten Bremsfangvorrichtung aus.The advantages achieved by the invention are essentially to be seen in the fact that the simple construction of the individual parts enables largely automated manufacture of the brake safety device. Another advantage is the simple adjustment work to adapt the braking delay to the different total weights of the elevator car and counterweight. Automated production as well as simple adjustment work have a positive effect on the manufacturing costs of the large number of brake safety devices.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Es zeigen:

In den Fig. 1 bis 4 ist mit 1 ein Gehäuse mit einer sich auf der Gehäusevorderseite über die gesamte Gehäusehöhe erstreckenden Ausnehmung 2 bezeichnet, an deren einen Ende eine Bremsplatte 3 angeordnet ist, neben welcher ein freier Schenkel 4 einer Führungsschiene 5 eintaucht. In den an den Schenkel 4 angrenzenden Teil der Ausnehmung 2 ist ein trapezförmiger Bügel 6 mit einem aus dem Gehäuse 1 ragenden rechteckförmigen Fortsatz 7 eingelegt. Der Bügel 6 weist führungsschienenseitig eine schräg nach oben verlaufende, einen Keilspalt 8 bildende Kulisse 9 mit U-förmigem Querschnitt auf, die unten und oben in ein kreisförmiges Ende übergeht. Die beiden Stirnflächen der Kulisse 9 dienen als Rollbahnen 10 für an einer zylinderförmigen, an der Manteloberfläche gerändelten Fangrolle 11 angeordnete Rollenachsen 12. Im unteren Teil der Kulisse 9 ist eine Überhöhung in der Form einer zusätzlichen Steuerschräge 13 vorgesehen, mit der die Fangrolle 11 rascher an den freien Schenkel 4 der Führungsschiene 5 geführt wird. Die Ausnehmung 2 endet an der der Bremsplatte 3 gegenüberliegenden Seite mit einer Keilschräge 14, an der der Bügel 6 anliegt. Ein in vertikaler Richtung durch den Bügel 6 und bis tief in den Fortsatz 7 hinein verlaufender Langschlitz 15 verleiht dem Bügel 6 das notwendige Federvermögen.1 to 4, 1 denotes a housing with a recess 2 extending on the front of the housing over the entire height of the housing, at one end of which a brake plate 3 is arranged, next to which a free leg 4 of a guide rail 5 is immersed. A trapezoidal bracket 6 with a rectangular extension 7 protruding from the housing 1 is inserted into the part of the recess 2 adjoining the leg 4. The bracket 6 has on the guide rail side an obliquely upward-extending link 9 which forms a wedge gap 8 and has a U-shaped cross section, which merges into a circular end at the top and bottom. The two end faces of the link 9 serve as runways 10 for roller axles 12 arranged on a cylindrical catch roller 11 knurled on the surface of the jacket. In the lower part of the link 9 there is an elevation in the form of an additional control bevel 13 provided with which the catch roller 11 is guided more quickly to the free leg 4 of the guide rail 5. The recess 2 ends on the side opposite the brake plate 3 with a wedge bevel 14 on which the bracket 6 rests. A slot 15 extending in the vertical direction through the bracket 6 and deep into the extension 7 gives the bracket 6 the necessary resilience.

Das eine Ende einer Schraube 16 steht mit dem an einem Träger 17 angeordneten Gehäuse 1, das andere Ende der Schraube 16 steht mit einer am dem Fortsatz 7 angeordneten Lasche 21 in Verbindung. Eine mittels der Schraube 16 bewirkte Höhenverstellung A des Fortsatzes 7 hat eine Querverstellung B des Bügels 6 zur Folge. Dabei gleitet der durch eine Abdeckplatte 18 verschiebbar gehaltene Bügel 6 entlang der Keilschräge 14 und verändert den Abstand der Fangrolle 11 zum freien Schenkel 4 der Führungsschiene 5. Der Abstand der Fangrolle 11 zum freien Schenkel 4 bestimmt wiederum die an unterschiedliche Gesamtgewichte von Aufzugskabine und Gegengewicht anzupassende Bremsfangverzögerung wie auch die mit C bezeichnete Einfederung des Bügels 6.One end of a screw 16 is connected to the housing 1 arranged on a carrier 17, the other end of the screw 16 is connected to a tab 21 arranged on the extension 7. A height adjustment A of the extension 7 effected by means of the screw 16 results in a transverse adjustment B of the bracket 6. The bracket 6, which is slidably held by a cover plate 18, slides along the wedge bevel 14 and changes the distance between the catching roller 11 and the free leg 4 of the guide rail 5. The distance between the catching roller 11 and the free leg 4 in turn determines the distance to be adapted to different total weights of the elevator car and the counterweight Brake delay as well as the deflection of the bracket 6, designated C.

Im Störfall betätigt ein nicht dargestellter Geschwindigkeitsbegrenzer mittels Zugorgane ein mit 19 bezeichnetes Hebelwerk, das mit einem Ende eines in die Ausnehmung 2 eintauchenden Betätigungsarms 20 in Verbindung steht. Die am anderen Ende des Betätigungsarm 20 drehbar angeordnete Fangrolle 11 wird dabei aus ihrer Ruhelage ausgelenkt und im Keilspalt 8 nach oben gezogen, wobei die Rollenachsen 12 den durch die Rollbahnen 10 vorherbestimmten Weg abrollen. Durch die nach oben gerichtete Relativbewegung entlang der Rollbahn 10 der Fangrolle 11 wird die Bremsplatte 3 zum freien Schenkel 4 der Führungsschiene 5 in Eingriff gebracht. Über den federnden Bügel 6 wird die Fangrolle 11 ohne innere Reibungsverluste immer stärker an den freien Schenkel 4 angedrückt und die Aufzugskabine beziehungsweise das Gegengewicht bis zum Stillstand abgebremst.In the event of a malfunction, a speed limiter (not shown) actuates a lever mechanism, designated 19, by means of traction elements, which is connected to one end of an actuating arm 20 which plunges into the recess 2. The catch roller 11, which is rotatably arranged at the other end of the actuating arm 20, is deflected from its rest position and pulled upwards in the wedge gap 8, the roller axes 12 rolling off the path predetermined by the roller tracks 10. Due to the upward relative movement along the runway 10 of the catching roller 11, the brake plate 3 becomes the free leg 4 the guide rail 5 brought into engagement. About the resilient bracket 6, the catch roller 11 is pressed more and more against the free leg 4 without internal friction losses and the elevator car or the counterweight is braked to a standstill.
