ZweckmĂ€Ăigerweise bildet die Abstandsmesseinrichtung den festen Messpunkt. Das vereinfacht das Verfahren. Es entfallen aufwĂ€ndige Justierarbeiten gegenĂŒber einem z. B. als Spiegel ausgebildeten festen Messpunkt sowie ggf. erforderliche Kabelverlegearbeiten zu einem Computer.Conveniently, the distance measuring device forms the fixed measuring point. This simplifies the procedure. It eliminates complex adjustments compared to a z. B. designed as a mirror fixed measuring point and possibly required cable laying work to a computer.
In der Praxis hat es sich als besonders vorteilhaft erwiesen, dass die Abstandsmesseinrichtung in einen Aufzugsschachtgrubenraum gesetzt wird, welcher durch einen Boden des Aufzugsschachts, dessen WĂ€nde und eine gedachte FlĂ€che begrenzt ist, welche auf einer Oberseite von auf dem Boden abgestĂŒtzten Puffern aufliegt. Der Aufzugsschachtgrubenraum ist relativ einfach begehbar. Unterhalb der gedachten FlĂ€che, welche auf der Oberseite der Puffer aufliegt, kann die Abstandsmesseinrichtung sicher untergebracht werden. Selbst bei einem Aufsetzen des Fahrkorbs oder des Gegengewichts auf den Puffern ist eine BeschĂ€digung der Abstandsmessvorrichtung nicht zu befĂŒrchten. Nach einer besonders einfachen Ausgestaltung wird die Abstandsmesseinrichtung auf dem Boden des Aufzugsschachtgrubenraums abgestĂŒtzt.In practice, it has proved to be particularly advantageous that the distance measuring device is placed in a hoistway pit space which is bounded by a floor of the hoistway, its walls and an imaginary surface which rests on an upper surface of bumpers supported on the ground. The lift pit mine is relatively easy to walk on. Below the imaginary surface, which rests on top of the buffer, the distance measuring device can be safely accommodated. Even with a placement of the car or the counterweight on the buffers damage to the distance measuring device is not to be feared. According to a particularly simple embodiment, the distance measuring device is supported on the floor of the hoistway pit area.
Nach einer weiteren besonders vorteilhaften Ausgestaltung der Erfindung wird als Abstandsmesseinrichtung ein optischer Distanzsensor verwendet, welcher einen entlang einer optischen Achse Sendelichtstrahlen emittierenden Sensor, wenigstens einen Oszillator zur Modulation der Sendelichtstrahlen und einen Empfangslichtstrahl empfangenden EmpfĂ€nger mit Mitteln zur Bestimmung der Laufzeit der von der Fahrkorbunterseite reflektierten Empfangslichtstrahlen aufweist. Mit dem vorgeschlagenen optischen Distanzsensor kann insbesondere die zeitliche Ănderung des Abstands des Fahrkorbs aus der Phasendifferenz zwischen Sende- und Empfangslichtstrahl bestimmt werden.According to a further particularly advantageous embodiment of the invention, an optical distance sensor is used as the distance measuring device, which comprises a along an optical axis transmitting light rays emitting sensor, at least one oscillator for modulating the transmitted light beams and a receiving light beam receiving receiver with means for determining the transit time of the reflected from the car bottom receiving light beams having. With the proposed optical distance sensor, in particular the time change of the distance of the car from the phase difference between the transmitted and received light beam can be determined.
Der Sende- und der Empfangslichtstrahl sind bei dieser Ausgestaltung nicht gepulst. Die Entfernungsmessung erfolgt durch Frequenzmessung.The transmitting and the receiving light beam are not pulsed in this embodiment. The distance measurement is done by frequency measurement.
Eine solche Frequenzmessung kann mit geringem Schaltungsaufwand bewerkstelligt werden. Es ist damit möglich, die zeitliche Ănderung eines Abstands zwischen der Fahrkorbunterseite und dem festen Messpunkt besonders exakt und mit hoher Auflösung zu messen.Such a frequency measurement can be accomplished with little circuit complexity. It is thus possible to measure the change over time of a distance between the underside of the car and the fixed measuring point particularly accurately and with high resolution.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass die Mittel zur Bestimmung der Laufzeit einen Phasendifferenzdetektor umfassen, welcher mit dem EmpfĂ€nger ĂŒber einen elektrischen Signalweg verbunden ist. In den elektrischen Signalweg kann eine elektronische Signalverzögerungseinheit eingeschaltet sein, mit der eine Phasendifferenz zwischen Sende- und Empfangslichtstrahlen auf einen vorgegebenen Wert eingestellt oder eingeregelt wird. Zur Bestimmung der Phasenverschiebung ist zweckmĂ€Ăigerweise zwischen Sende- und Empfangslichtstrahlen wenigstens ein Synchrongleichrichter vorgesehen. Der Sender kann durch einen vorgeschalteten Oszillator mit einer konstanten Frequenz moduliert sein, so dass der Ausgang eines Taktoszillators auf den Synchrongleichrichter gefĂŒhrt ist, wobei die Frequenz des Taktoszillators durch RĂŒckkopplung des Ausgangssignals des Synchrongleichrichters einstellbar ist. In einem Phasendetektor kann die Phasendifferenz zwischen den Signalen des Oszillators und des Taktoszillators bestimmt und in der Auswerteeinheit als MaĂ fĂŒr den Abstand ausgewertet werden. Es kann auch sein, dass zur Bestimmung der Phasenverschiebung zwischen Sende- und Empfangslichtstrahlen die Modulationsfrequenz der Sendelichtstrahlen einstellbar ist, indem auf einem den Sender vorgeschalteten Oszillator das integrierte Ausgangssignal des Synchrongleichrichters rĂŒckgekoppelt ist, wobei die im Oszillator eingestellte Modulationsfrequenz in der Auswerteinheit als MaĂ fĂŒr den Abstand ausgewertet wird. Eine Abstandsmesseinrichtung mit den vorgenannten Merkmalen eignet sich zur Messung des Abstands des Fahrkorbs gegenĂŒber dem festen Messpunkt besonders gut. Eine damit erreichbare Messfrequenz ermöglicht eine Messung der zeitlichen Ănderung des Abstands im Millisekundenbereich. Damit können Verzögerungen und/oder Beschleunigungen erfasst werden, wie sie beispielsweise beim Auslösen einer Fangvorrichtung, bei Nothalt oder dgl., auftreten. Die vorgeschlagene Abstandsmesseinrichtung eignet also universell zur Ermittlung aller geschwindigkeits- und/oder beschleunigungsabhĂ€ngigen Kennwerte bei der PrĂŒfung der ordnungsgemĂ€Ăen FunktionsfĂ€higkeit eines Aufzugs.According to a further embodiment of the invention, it is provided that the means for determining the transit time comprise a phase difference detector, which is connected to the receiver via an electrical signal path. In the electrical signal path, an electronic signal delay unit can be turned on, with which a phase difference between transmitting and receiving light beams is set or adjusted to a predetermined value. For determining the phase shift, at least one synchronous rectifier is expediently provided between transmitting and receiving light beams. The transmitter can be modulated by a preceding oscillator at a constant frequency, so that the output of a clock oscillator is fed to the synchronous rectifier, wherein the frequency of the clock oscillator is adjustable by feedback of the output signal of the synchronous rectifier. In a phase detector, the phase difference between the signals of the oscillator and the clock oscillator can be determined and evaluated in the evaluation unit as a measure of the distance. It may also be that for determining the phase shift between transmitting and receiving light beams, the modulation frequency of the transmitted light beams is adjustable by the integrated output signal of the synchronous rectifier is fed back on a transmitter upstream of the oscillator, wherein the set in the oscillator modulation frequency in the evaluation unit as a measure of the Distance is evaluated. A distance measuring device with the aforementioned features is particularly suitable for measuring the distance of the car relative to the fixed measuring point. A measurement frequency achievable thereby enables a measurement of the temporal change of the distance in the millisecond range. This delay and / or accelerations can be detected, as they occur, for example, when triggering a safety gear, emergency stop or the like .. The proposed distance measuring device is thus universally suitable for determining all speed and / or acceleration-dependent characteristic values when testing the proper functioning of an elevator.
Vorteilhafterweise ist der optische Distanzsensor auf dem Boden der Aufzugsschachtgrube abgestĂŒtzt und an der Fahrkorbunterseite ist ein Reflektor angebracht. Das AbstĂŒtzen des optischen Distanzsensors auf dem Schachtboden lĂ€sst sich besonders einfach bewerkstelligen. UmstĂ€ndliche Montagearbeiten sind nicht erforderlich.Advantageously, the optical distance sensor is supported on the floor of the hoistway pit, and a reflector is attached to the underside of the car. The support of the optical distance sensor on the shaft bottom can be accomplished particularly easily. Cumbersome installation work is not required.
Nach einer weiteren Ausgestaltung ist eine Auswerteeinheit zur Auswertung der am Ausgang des EmpfĂ€ngers anstehenden Empfangssignale vorgesehen. Der EmpfĂ€nger kann eine lichtempfindliche FlĂ€che aufweisen, deren Normalvektor um einen vorgegebenen Kippwinkel zur optischen Achse geneigt ist. Damit kann vermieden werden, dass vom EmpfĂ€nger Licht in den Bereich der optischen Achse reflektiert wird, was zu einer VerfĂ€lschung der Messergehnisse fĂŒhren könnte. Der Kipp winkel liegt zweckmĂ€Ăigerweise im Bereich von 10 bis 30°.In accordance with a further embodiment, an evaluation unit is provided for evaluating the received signals present at the output of the receiver. The receiver may have a photosensitive surface whose normal vector is tilted by a predetermined tilt angle to the optical axis. This can be avoided that light is reflected by the receiver in the region of the optical axis, which could lead to a falsification of Messergehnisse. The tilt angle is suitably in the range of 10 to 30 °.
Zur Auswertung der Messwerte hat es sich als besonders vorteilhaft erwiesen, einen Tiefpassfilter, vorzugsweise einen SG- FIR-Tiefpassfilter, zu verwenden und die Messwerte damit zu filtern. Die Kombination des optischen Distanzsensors mit dem vorgeschlagenen Filter fĂŒhrt zu besonders zuverlĂ€ssigen Ergebnissen.To evaluate the measured values, it has proven to be particularly advantageous to use a low-pass filter, preferably an SG-FIR low-pass filter, and to filter the measured values with it. The combination of the optical distance sensor with the proposed filter leads to particularly reliable results.
Zur Ermittlung des Kennwerts wird der Abstand in AbhĂ€ngigkeit der Zeit gemessen und daraus eine Beschleunigung des Fahrkorbs ermittelt. Die Beschleunigung kann dabei einfach und exakt durch zweifache Ableitung der ĂŒber der Zeit gemessenen Abstandswerte ermittelt werden. Auf der Grundlage einer derart ermittelten Beschleunigung können eine Vielzahl von die ordnungsgemĂ€Ăe FunktionsfĂ€higkeit eines Aufzugs wiedergegebenen Kennwerten ermittelt werden.To determine the characteristic value, the distance is measured as a function of time and from this an acceleration of the car is determined. The acceleration can be determined simply and accurately by twice the derivative of the distance values measured over time. On the basis of such ascertained acceleration, a multiplicity of characteristic values reproduced for the proper functioning of an elevator can be determined.
Nach einer ersten Alternative des Verfahrens werden bei einem zu prĂŒfenden Aufzug, bei dem der Fahrkorb mit einer Fangvorrichtung versehen und ĂŒber zumindest ein ĂŒber eine Treibscheibe gefĂŒhrtes Seil mit einem Gegengewicht verbunden ist, zur Ermittlung eines die FunktionsfĂ€higkeit der Fangvorrichtung wiedergebenden Kennwerts die folgenden Schritte durchgefĂŒhrt:
- AbwÀrtsbewegen des Fahrkorbs;
- Auslösen der Fangvorrichtung;
- Messen eines Abstands des Fahrkorbs gegenĂŒber dem festen Messpunkt gegenĂŒber der Zeit; und
- Ermitteln der durch das Auslösen der Fangvorrichtung bewirkten Verzögerung Vf des Fahrkorbs aus den Messwerten.
- Moving the car down;
- Triggering the safety gear;
- Measuring a distance of the car from the fixed measuring point with respect to time; and
- Determining the caused by the triggering of the safety gear delay Vf of the car from the measured values.
Indem unmittelbar eine AbstandsĂ€nderung des Fahrkorbs gegen ĂŒber dem festen Messpunkt ĂŒber der Zeit gemessen wird, kann die Verzögerung des Fahrkorbs beim Auslösen der Fangvorrichtung besonders genau ermittelt werden. Das Verfahren lĂ€sst sich ĂŒberraschend einfach durchfĂŒhren. Insbesondere ist es nicht erforderlich, eine Messvorrichtung an einem Seil, der Treibscheibe oder dgl., anzubringen.By directly measuring a distance change of the car relative to the fixed measuring point over time, the delay of the car when the safety gear is triggered can be determined particularly accurately. The process can be carried out surprisingly easily. In particular, it is not necessary to attach a measuring device to a cable, the traction sheave or the like.
Nach einer vorteilhaften Ausgestaltung wird das AbwĂ€rtsbewegen mit unbeladenem Fahrkorb durchgefĂŒhrt. Das vereinfacht das erfindungsgemĂ€Ăe Verfahren. ZweckmĂ€Ăigerweise wird die Fangvorrichtung in einer unteren HĂ€lfte, vorzugsweise einem unteren Drittel, besonders bevorzugt in einem unteren Viertel, eines Fahrwegs des Fahrkorbs ausgelöst. Wegen der damit zunehmenden SeillĂ€nge zwischen Treibscheibe und Fahrkorb wird die Fangvorrichtung in einem unteren Abschnitt des Fahrwegs besonders stark beansprucht. FĂŒr die FunktionsfĂ€higkeit der Fangvorrichtung ergeben sich in einem unteren Abschnitt des Fahrwegs besonders aussagekrĂ€ftige Werte.According to an advantageous embodiment, the downward movement is carried out with unladen car. This simplifies the method according to the invention. Conveniently, the safety gear is triggered in a lower half, preferably a lower third, more preferably in a lower quarter of a travel path of the car. Because of the increasing rope length between traction sheave and car, the safety gear is particularly heavily stressed in a lower portion of the driveway. For the functionality of the safety gear results in a lower portion of the track particularly meaningful values.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung wird das AbwĂ€rtsbewegen mit Nenngeschwindigkeit durchgefĂŒhrt. Das vereinfacht weiter das vorgeschlagene Verfahren.According to a further advantageous embodiment of the invention, the downward movement is carried out at rated speed. This further simplifies the proposed method.
Die Verzögerung Vf fĂŒr den mit Nennlast beladenen Fahrkorb kann nach der folgenden Formel ermittelt werden:
wobei gilt:
- NL
- = Im Fahrkorb angegebene Nennlast
- g
- = Erdbeschleunigung
- s
- = 2te Ableitung des gemessenen Abstands nach der Zeit und
- mFK
- = Masse des Fahrkorbs
where:
- NL
- = Nominal load stated in the car
- G
- = Gravitational acceleration
- s
- = 2nd derivative of the measured distance with time and
- MFK
- = Mass of the car
Nach einer zweiten Alternative des Verfahrens werden, bei einem zu prĂŒfenden Aufzug, bei dem der Fahrkorb ĂŒber zumindest ein ĂŒber eine Treibscheibe gefĂŒhrtes Seil mit einem Gegengewicht verbunden und eine Bremseinrichtung zum Abbremsen der Treibscheibe vorgesehen ist, die folgenden Schritte zur Ermittlung eines eine TreibfĂ€higkeit T der Treibscheibe beschreibenden Kennwerts durchgefĂŒhrt:
- Bewegen des Fahrkorbs;
- Auslösen der Bremseinrichtung;
- Messen eines Abstands des Fahrkorbs gegenĂŒber einem festen Messpunkt ĂŒber der Zeit; und
- Ermittlung der TreibfÀhigkeit T der Treibscheibe aus den gemessenen Werten.
- Moving the car;
- Triggering the braking device;
- Measuring a distance of the car from a fixed measuring point over time; and
- Determination of the driving capability T of the traction sheave from the measured values.
Indem vorteilhafterweise der Abstand der Fahrkorbunterseite gemessen wird, lĂ€sst sich das vorgeschlagene Verfahren ĂŒberraschend einfach und schnell durchfĂŒhren. Es kann insbesondere auf die zeitaufwĂ€ndige Montage von Messwertaufnehmern an Seilen, der Treibscheibe oder dgl. Verzichtet werden. Abgesehen davon kann aus einer Messung der Ănderung des Abstands des Fahrkorbs gegenĂŒber einem festen Messpunkt die TreibfĂ€higkeit der Treibscheibe beim Auslösen der Bremseinrichtung mit verbesserter Genauigkeit ermittelt werden.By advantageously measuring the distance of the underside of the car, the proposed method can be carried out surprisingly easily and quickly. In particular, it can be dispensed with the time-consuming installation of transducers on ropes, the traction sheave or the like. Apart from that, from a measurement of the change in the distance of the car from a fixed measuring point, the driving ability of the traction sheave when triggering the braking device can be determined with improved accuracy.
Im Sinne der vorliegenden Erfindung wird unter dem Begriff "Bremseinrichtung" eine direkt auf die Treibscheibe wirkende Treibscheibenbremse oder auch eine indirekt auf die Treibscheibe wirkende Getriebe- oder Motorbremse verstanden. Der Begriff "Aufzugsschacht" ist im Sinne der vor liegenden Erfindung ebenfalls allgemein zu verstehen. Darunter werden sowohl voll- als auch teilumwehrte AufzugsschĂ€chte verstanden. Im Sinne der vorliegenden Erfindung handelt es sich bei dem "Abstand" um eine im Wesentlichen in Bewegungsrichtung des Fahrkorbs gemessene Distanz. Unter einem "Aufzug" wird sowohl ein Aufzug mit einem in vertikaler Richtung verfahrbaren Fahrkorb als auch ein SchrĂ€gaufzug verstanden, bei dem der Fahrkorb um zumindest 15° schrĂ€g gegenĂŒber der Waagerechten verfahrbar ist.For the purposes of the present invention, the term "braking device" is understood to mean a traction disk brake acting directly on the traction sheave or else a transmission or engine brake acting indirectly on the traction sheave. The term "elevator shaft" is also generally understood in the sense of the present invention. This includes both fully and partially reinforced lift shafts. For the purposes of the present invention, the "distance" is a distance measured essentially in the direction of movement of the car. An "elevator" is understood to mean both an elevator with a car which can be moved in the vertical direction and an inclined elevator, in which the car can be moved at least 15 ° obliquely in relation to the horizontal.
Mit dem vorgeschlagenen Verfahren kann insbesondere die TreibfĂ€higkeit bei Nothalt im Sinne der DIN EN 81-1 ermittelt werden. zu diesem Zweck wird unmittelbar der Abstand des Fahrkorbs ĂŒber der Zeit beim Bewegen des Fahrkorbs gemessen und die Bremseinrichtung ausgelöst. Die Verzögerung der Bewegung nach Auslösen der Bremseinrichtung lĂ€sst sich aus dem gemessenen Abstand durch zweifache Ableitung nach der Zeit ermitteln.With the proposed method, in particular the driving capability for emergency stop in the sense of DIN EN 81-1 can be determined. For this purpose, the distance of the car over time when moving the car is measured directly and triggered the braking device. The delay of the movement after release of the braking device can be determined from the measured distance by two-fold derivation after the time.
Im Gegensatz zum Stand der Technik ist es hier nicht erforderlich, zur Berechnung auf Integrationskonstanten zurĂŒckzugreifen. Die Verwendung von Integrationskonstanten fĂŒhrt bei der Berechnung zu Ungenauigkeiten.In contrast to the prior art, it is not necessary here to resort to calculation constants of integration. The use of integration constants leads to inaccuracies in the calculation.
Vorteilhafterweise wird das Bewegen mit unbeladenem Fahrkorb durchgefĂŒhrt. Das erhöht weiter die Effizienz des vorgeschlagenen Verfahrens. SelbstverstĂ€ndlich ist es auch möglich, den Fahrkorb beispielsweise mit Nennlast zu beladen.Advantageously, the movement is carried out with the car unloaded. This further increases the efficiency of the proposed method. Of course, it is also possible to load the car, for example, with nominal load.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung wird das Bewegen des Fahrkorbs mit Nenngeschwindigkeit durchgefĂŒhrt. Das vereinfacht weiter das vorgeschlagene Verfahren.According to a further advantageous embodiment of the invention, the moving of the car is carried out at rated speed. This further simplifies the proposed method.
ZweckmĂ€Ăigerweise wird der Fahrkorb zur Ermittlung der TreibfĂ€higkeit T aufwĂ€rts bewegt. Mit dem erfindungsgemĂ€Ăen Verfahren ist es aber auch möglich, die TreibfĂ€higkeit einer AbwĂ€rtsbewegung des Fahrkorbs mit einer hohen Genauigkeit zu bestimmen.Conveniently, the car is moved up to determine the driving ability T. With the method according to the invention, it is also possible to determine the driving ability of a downward movement of the car with a high accuracy.

Dazu hat es sich als zweckmĂ€Ăig erwiesen, auf zumindest einem zum Gegengewicht korrespondierenden ersten Puffer eine erste Kraftmesseinrichtung und auf zumindest einem zum Fahrkorb korrespondierenden zweiten Puffer eine zweite Kraftmesseinrichtung abzustĂŒtzen. Die Kraftmesseinrichtungen werden also ebenfalls in die Aufzugsschachtgrube eingebracht und befinden sich damit in der NĂ€he der Abstandsmesseinrichtung. Das ermöglicht es vorteilhafterweise, die Messwerte der Abstandsmesseinrichtung und/oder der Kraftmesseinrichtungen mittels eines damit verbundenen, vorzugsweise in den Aufzugsschachtgrubenraum gesetzten, Computers zu erfassen und auszuwerten. Das Einrichten einer die Kraftmesseinrichtungen, die Abstandsmesseinrichtung sowie den Computer umfassenden Messeinrichtung in der Aufzugsschachtgrube lĂ€sst sich schnell und einfach durchfĂŒhren. Mit einer solchen Messeinrichtung können sĂ€mtliche zur PrĂŒfung der ordnungsgemĂ€Ăen FunktionsfĂ€higkeit eines Aufzugs erforderlichen Kennwerte ermittelt werden.To test the proper functioning of an elevator, it is also necessary, in addition to the described method for testing the TreibfĂ€higkei emergency stop, to determine other characteristics. For this purpose, the method according to the invention, which forms a test sequence, can be combined with further test sequences. For this purpose, it has proven expedient to support a first force measuring device on at least one first buffer corresponding to the counterweight and a second force measuring device on at least one second buffer corresponding to the car. The force measuring devices are thus also introduced into the elevator shaft pit and are thus in the vicinity of the distance measuring device. This advantageously makes it possible to record and evaluate the measured values of the distance measuring device and / or of the force measuring devices by means of a computer connected thereto, preferably in the elevator shaft pit space. The establishment of a force measuring devices, the distance measuring device and the computer comprehensive measuring device in the hoistway pit can be performed quickly and easily. With such a measuring device all required to check the proper functioning of an elevator characteristics can be determined.
