Description
Die Erfindung betrifft eine Bremsfangvorrichtung für das Lastaufnahmemittel einer Vertikalfördereinrichtung mit mindestens einem in einem Gehäuse (1) angeordneten Bremskeil (3,4), der bei Auslösung eines Bremsvorganges auf eine Führungsschiene (2) des Förderfahrzeuges einwirkt und mit einem Anschlag, welcher den Hub des mindestens einen Bremskeils (3, 4) und somit die maximale Bremskraft während des Bremsvorganges begrenzt. Ausserdem betrifft die Erfindung ein Verfahren zur Anpassung der Bremskraft dieser Bremsfangvorrichtung an die am Lastaufnahmemittel wirkenden abzubremsenden Massen.The invention relates to a safety brake device for the Load-receiving means of a vertical conveyor with at least one brake wedge arranged in a housing (1) (3,4), when a braking operation on a Guide rail (2) of the conveyor vehicle acts and with a stop which the stroke of the at least one brake wedge (3, 4) and thus the maximum braking force during the Braking limited. In addition, the invention relates a method for adjusting the braking force of this brake device to be braked on the load receiving means Masses.
Eine derartige Bremsfangvorrichtung ist bereits aus der EP-A-0825145 bekannt.Such a brake device is already known from EP-A-0825145.
Derartige Bremsfangvorrichtungen werden beispielsweise bei Personenaufzügen, Lastenaufzügen und für Fahrkörbe bei Schachtförderanlagen verwendet, wobei üblicherweise der Bremsvorgang bei Ueberschreiten einer zulässigen Fahrgeschwindigkeit durch ein auf die Bremskeile einwirkendes Begrenzerseil eines Geschwindigkeitsbegrenzers ausgelöst wird.Such brake devices are for example at Passenger lifts, goods lifts and for cars Schachtförderanlagen used, usually the Braking operation when exceeding a permissible travel speed by a force acting on the brake wedges Limiter rope of a speed limiter triggered becomes.
Mit der Oesterreichischen Patentschrift Nr.297260 ist eine Bremsfangvorrichtung gemäss Oberbegriff bekannt geworden, bei der eine an der Aufzugskabine befestigte, aus Winkelprofilen bestehende Gleitführung für ein Keilgehäuse vorgesehen ist. Das Keilgehäuse weist eine in senkrechter Richtung konisch verlaufende Ausnehmung auf, in der zwei Bremskeile angeordnet sind, welche die Führungsschiene des Aufzuges mit Spiel umgeben. Die Bremskeile sind in Nuten der Ausnehmung auf Kugeln rollbar gelagert, so dass an den Keilflächen von Keilgehäuse und Bremskeilen bei deren Bewegung nur ein geringer Rollwiderstand entsteht. Die beiden Bremskeile können von einem Doppelhebel bewegt werden, der auf einer Welle sitzt, die über einen Hebel vom Begrenzerseil eines Geschwindigkeitsbegrenzers verdreht wird. Bei Ueberschreiten der zulässigen Geschwindigkeit des Aufzuges werden die Bremskeile gegen die Führungsschiene gedrückt und der Bremsvorgang eingeleitet. Ueber dem Keilgehäuse ist von der Kabine abstehend eine Abstützkonsole befestigt, gegen die sich das Keilgehäuse über Tellerfedern abstützt. An der Abstützkonsole sind mit Muttern gesicherte Stellschrauben angeordnet, die als Anschläge für die Bremskeile dienen. Während des Bremsvorganges werden die Bremskeile soweit in das Keilgehäuse eingezogen, wie es der Dicke der Führungsschiene entspricht. Die dabei auftretenden Bremskräfte bewirken, dass das Keilgehäuse gegen die Tellerfedern angehoben wird, bis die Bremskeile an den Stellschrauben anschlagen, wodurch ein weiteres Ansteigen der Bremskräfte verhindert wird.With the Austrian Patent No. 297260 is a Safety brake device according to the preamble has become known, in the one attached to the elevator car, made of angle profiles existing sliding provided for a wedge housing is. The wedge housing has a vertical direction tapered recess on, in the two chocks are arranged, which the guide rail of the elevator with Surround the game. The brake wedges are in grooves of the recess Rolled on balls, so that on the wedge surfaces of Wedge housing and chocks when moving only one low rolling resistance arises. The two brake wedges can be moved by a double lever on one side The shaft sits over a lever off the governor rope Speed limiter is twisted. When crossing the permissible speed of the elevator will be the Brake wedges pressed against the guide rail and the braking process initiated. Above the wedge housing is from the Cabin mounted a support bracket attached against the the wedge housing is supported by disc springs. At the Support bracket are secured with nuts set screws arranged, which serve as stops for the brake wedges. During the braking process, the brake wedges are in so far the wedge housing retracted, as is the thickness of the guide rail equivalent. The occurring braking forces cause the wedge housing to lift against the Belleville springs until the chocks hit the set screws, causing a further increase in braking forces is prevented.
Die vorstehend beschriebene Bremsfangvorrichtung hat den Nachteil, dass bei unterschiedlichen abzubremsenden Massen unterschiedliche Verzögerungswerte am Lastaufnahmemittel erzeugt werden. Bei grossen Lasten im Lastaufnahmemittel kann somit eine zu geringe Verzögerung, bei kleinen Lasten eine unzulässig hohe Verzögerung des Lastaufnahmemittels auftreten und damit zu Personen- und Sachschäden führen.The above-described safety brake device has the Disadvantage that at different braked masses different deceleration values on the load handling device be generated. For heavy loads in the load handling device can thus be too low a delay, with small loads an inadmissibly high delay of the load handling device occur and thus lead to personal injury and property damage.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Bremsfangvorrichtung gemäss Oberbegriff vorzuschlagen, die diese Nachteile nicht aufweist.The invention is therefore based on the object, a brake device to propose according to the generic term, this Disadvantages not.
Diese Aufgabe wird durch die in den unabhängigen Patentansprüchen
1 und 8 angegebene Erfindung gelöst. Hierbei ist
eine Stelleinrichtung vorgesehen, die durch Verschieben von
mindestens einem Anschlag oder des Gehäuses die im Fall
einer Fangbremsung auftretende Einfederung von Federelementen
und somit die daraus resultierenden Federkräfte bestimmt,
wobei diese Federelemente mit den genannten Federkräften
die Bremskeile gegen die Führungsschienen des Lastaufnahmemittels
pressen. Mittels der Stelleinrichtung kann
also der mindestens eine Anschlag oder das Gehäuse in Abhängigkeit
von der Grösse der abzubremsenden Masse des Lastaufnahmemittels
verstellt und damit die Bremskraft zwischen den
Bremskeilen und der Führungsschiene beeinflusst werden.This object is achieved by the in the
Die mit der Erfindung erzielten Vorteile sind insbesondere darin zu sehen, dass unabhängig von der Grösse der aktuell im Lastaufnahmemittel vorhandenen Last bei der Bremsung eine definierte Verzögerung von einer Grösse erreicht werden kann, bei der Personen- und Sachschäden vermieden werden.The advantages achieved by the invention are in particular to see that regardless of the size of the current in the load handler existing load during braking one defined delay of one size can be achieved can be avoided in the case of personal injury and property damage.
Ein weiterer Vorteil ist darin zu sehen, dass die Verstellung des Anschlages oder des Gehäuses kontinuierlich während der Fahrt erfolgen kann. Dies ist bei Vertikalfördereinrichtungen wichtig, die Ausgleichsgewichte aufweisen und mit Ausgleichsseilen ausgerüstet sind, die zwischen der Unterseite des Lastaufnahmemittels und derjenigen des Ausgleichsgewichts hängen. Da der eine Fangbremsung zusätzlich beeinflussende Anteil der Masse der genannten Ausgleichsseile sich während der Fahrt verändert, ist es vorteilhaft, dass die Position des Anschlags oder des Gehäuses, von der die im Fall einer Fangbremsung auftretende Bremskraft abhängt, laufend dieser Veränderung anpasst werden kann.Another advantage is the fact that the adjustment of the stop or housing continuously during the ride can be done. This is with vertical conveyors important to have the balance weights and with Equalizing cables are fitted between the bottom of the load-handling device and that of the balance weight hang. As the catch braking additionally influencing Share of the mass of the said compensating ropes It changes during the journey, it is advantageous that the position of the stop or the housing from which the im Case of a fall arrest braking force occurring, be constantly adapted to this change.

- a longitudinal section through a second inventive brake device in a simplified, schematic representation
In den Fig.1 und 2 ist mit 1 ein an einem nicht dargestellten
Lastaufnahmemittel einer Vertikalfördereinrichtung
befestigtes Gehäuse und mit 2 eine Führungsschiene des
Aufzuges bezeichnet. Im Gehäuse 1 sind zu beiden Seiten der
Führungsschiene 2 Bremskeile 3,4 angeordnet. Die Bremskeile
3,4 stützen sich über Gegenbacken 5,6 und Federelemente 7,8
im Gehäuse 1 ab, wobei die Gegenbacken 5,6 und die Federelemente
7,8 in Ausnehmungen 9,10 des Gehäuses 1 geführt werden.
Oberhalb der Bremskeile 3,4 ist ein Anschlag 11 vorgesehen,
der im Gehäuse 1 geführt wird und in Richtung des
Doppelpfeiles 12 auf und ab bewegt werden kann. Zu diesem
Zweck ist eine mit dem Anschlag in Wirkverbindung stehende
Stelleinrichtung 13 vorgesehen, mittels welcher der Anschlag
11 abhängig von den aktuell abzubremsenden Massen positioniert
werden kann. Diese Massen setzen sich hauptsächlich
aus der im Lastaufnahmemittel vorhandenen Last, dem Gewicht
der Kabine und dem aktuell wirksamen Gewichtsanteil der am
Lastaufnahmemittel hängenden Unterseile zusammen. Mit der
beschriebenen Massnahme kann der Hub der Bremskeile 3,4 und
davon abhängig der Kompressionsweg der Federelemente 7,8
sowie, daraus resultierend, die Bremskraft zwischen den
Bremskeilen 3,4 und der Führungsschiene 2 derart beeinflusst
werden, dass unabhängig von der Grösse der zu bremsenden
Massen im Fall einer Fangbremsung eine Verzögerung eintritt,
bei der einerseits das Lastaufnahmemittel sicher gestoppt
wird und andererseits keine Personen- oder Sachschäden
entstehen.In FIGS. 1 and 2, 1 is a not shown on a
Load-receiving means of a vertical conveyor
fixed housing and with 2 a guide rail of the
Elevator called. In the
Die Stelleinrichtung 13 kann beispielsweise einen Verstellantrieb
aufweisen, der einen Servomotor und eine von diesem
angetriebene Schraubenspindel enthält, mit der der Anschlag
11 positioniert wird. Die Stelleinrichtung 13 enthält ausserdem
eine Positionsregeleinrichtung, die in Abhängigkeit
von mehreren Eingangssignalen Stellsignale für den Servomotor
erzeugt. Ausgewertet werden mindestens ein Eingangssignal,
das die Position des Anschlags meldet, sowie ein von
einer Lastmesseinrichtung generiertes Signal, das die Grösse
der Last im Lastaufnahmemittel repräsentiert. In Fällen, wo
die Vertikalfördereinrichtung, wie vorstehend beschrieben,
mit Ausgleichsseilen ausgerüstet ist, kann ein weiteres
Eingangssignal berücksichtigt werden, das in Abhängigkeit
von der vertikalen Position des Lastaufnahmemittels die
veränderliche, aktuell wirksame Masse der Ausgleichsseile
repräsentiert.The adjusting
Selbstverständlich können für die Anschlagpositionierung auch Stelleinrichtungen anderer Art verwendet werden, wie beispielsweise hydraulisch betätigte Servo-Stellzylinder oder motorgetriebene Nockenscheiben.Of course, for the stop positioning Also actuators of other types are used, such as For example, hydraulically operated servo-actuating cylinder or motor driven cams.
Wie an sich bekannt, werden beim Ueberschreiten einer zulässigen
Geschwindigkeit die Bremskeile 3,4 über ein Begrenzerseil
eines Geschwindigkeitsbegrenzers und eine Hebelanordnung
angehoben. Infolge der Keilwirkung zwischen den Bremskeilen
3,4 und den der Gegenbacken 5,6 werden erstere gegen
die Führungsschiene 2 bewegt, bis sie an dieser anliegen.
Durch das Auftreten von Reibungskräften zwischen den Bremskeilen
3,4 und der Führungsschiene 2 werden die Bremskeile
3,4 bis zum Anschlag 11 nach oben gezogen, was eine Seitwärtsverschiebung
der Gegenbacken 5,6 durch die Keilwirkung
und die Einfederung der Federelemente 7,8 bewirkt. Die
zusammengepressten Federelemente 7,8 drücken nun die Bremskeile
3,4 gegen die Führungsschiene 2, wodurch zwischen
Bremskeilen und Führungsschiene eine von der Position des
Anschlags 11 abhängige, der Bewegung des Lastaufnahmemittels
entgegenwirkende Bremskraft entsteht.
Im Unterschied zur vorstehend beschriebenen Einrichtung, bei
der das Gehäuse 1 am Lastaufnahmemittel fixiert ist und der
Anschlag 11 durch die Stelleinrichtung 13 verschoben wird,
können in einer Ausführungsvariante der Anschlag 11 am
Lastaufnahmemittel fixiert sein und das Gehäuse 1 mit Bremskeilen
3,4, Gegenbacken 5,6 und Federelementen 7,8 verschoben
werden. Auslösung und Bremswirkung der Bremsfangvorrichtung
bleiben dabei praktisch unverändert.As is known per se, when a permissible speed is exceeded, the
In contrast to the device described above, in which the
Das Ausführungsbeispiel nach Fig. 3 weist anstelle des die
Endstellung des Bremskeils bestimmenden Anschlags 11 zwei im
Bereich der Ausnehmungen 9,10 in der Wand des Gehäuses 1
geführte Anschläge 15 auf. Diese bilden in Richtung der
Doppelpfeile 16 einstellbare Abstützungen für die Federelemente
7,8, mit deren Hilfe die im Fall einer Fangbremsung
durch die Keilwirkung der Bremskeile 3,4 auftretende Einfederung
der Federelemente 7,8 verändert werden kann. Zwei
Stelleinrichtungen 14 positionieren die genannten Anschläge
15 vor jeder Fahrt und gegebenenfalls auch während einer
Fahrt so, dass im Fall einer Fangbremsung die Einfederung
der Federelemente 7,8 und somit die daraus resultierende
Federkräfte, mit der die Federelemente 7,8 die Bremskeile
3,4 gegen die Führungsschienen 2 pressen, der aktuell abzubremsenden
Masse angepasst sind. Die funktionellen Eigenschaften
der Stelleinrichtungen 14 entsprechen denjenigen
der vorstehend beschriebenen Stelleinrichtung 13.The embodiment of FIG. 3 has instead of the
