Description
Die Erfindung betrifft einen Aufzug bestehend aus einer in einem Aufzugsschacht entlang von Führungsschienen verfahrbaren Aufzugskabine und einem Gegengewicht, wobei Aufzugskabine und Gegengewicht mittels eines über Rollen geführten Tragmittels verbunden sind und je Tragmittelende ein Fixpunkt vorgesehen ist und ein Antrieb das Tragmittel antreibt gemäss der Definition des unabhängigen Patentanspruchs.The invention relates to an elevator comprising an elevator car which can be moved in a lift shaft along guide rails and a counterweight, the elevator car and the counterweight being connected by means of a suspension element guided by rollers, and a fixed point is provided per support end and a drive drives the suspension element according to the definition of the independent one claim.
Ein Aufzug gemäß dem Oberbegriff des Anspruchs 1 ist z.B. aus
Aus der Patentschrift
Die Erfindung, wie sie in Anspruch 1 gekennzeichnet ist, löst die Aufgabe, bei einer Nothaltsituation Verzögerungen an einer Aufzugskabine auf ein für die Aufzugspassagiere erträgliches Mass abzuschwächen.The invention, as characterized in
Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.Advantageous developments of the invention are specified in the dependent claims.
Die Reibwerte von Riemen oder Kunstfaserseilen an der Treibscheibe sind wesentlich höher als die Reibwerte von Stahlseilen. Beim Einfallen der Antriebsbremse, beispielsweise bei einem durch den Sicherheitskreis ausgelösten Nothalt, ist der Schlupf an der Treibscheibe bei kunststoffummantelten Tragmitteln sehr viel geringer als bei Stahlseilen. Als Folge davon entstehen viel höhere Verzögerungswerte an und in der Aufzugskabine. Mit dem erfindungsgemässen Fixpunkt für die Tragmittelendverbindungen kann der Fahrkomfort auch bei modernen Tragmitteln in einer Nothaltsituation aufrecht erhalten werden. Besonders bei schnellfahrenden Aufzügen muss ein weiches Nothalten gewährleistet werden, zu hohe Verzögerungen würden in der Aufzugskabine zu Unfällen und Verletzungen der Aufzugspassagiere führen. Der erfindungsgemässe Fixpunkt ist bei Normalbetrieb fest mit der Führungsschiene oder mit dem Aufzugsschacht verbunden. Bei einem durch den Sicherheitskreis ausgelösten Nothalt wird der Fixpunkt mittels eines Mechanismus freigesetzt, wobei der Mechanismus und die Antriebsbremse gleichzeitig ausgelöst werden. Der Mechanismus setzt aber den Fixpunkt frei bevor das durch die Antriebsbremse erzeugte Bremsmoment zur Verzögerung der Aufzugskabine aufgebaut ist. Mit dem sich aufbauenden Bremsmoment tritt eine Verzögerung der Aufzugskabine ein, wobei ein Dämpfungselement des freigesetzten Fixpunktes einfedert und die Verzögerung auf ein für die Aufzugspassagiere erträgliches Mass abschwächt. Der Sicherheitskreis überwacht wesentliche sicherheitsrelevante Funktionen des Aufzuges und umfasst bevorzugt eine Serieschaltung von Kontakten zur Überwachung von beispielsweise Türstellungen der Kabinentür oder der Stockwerktüren, zur Überwachung der Übergeschwindigkeit der Aufzugskabine, zur Überwachung der Stromversorgung für die Aufzugssteuerung, zur Überwachung der Detektion des Schachtendes und so fort. Öffnet einer der Kontakte des Sicherheitskreises wird wie oben dargelegt ein Nothalt ausgelöst und die Antriebsbremse eingerückt und der Fixpunkt freigesetzt.The coefficients of friction of belts or synthetic ropes on the traction sheave are significantly higher than the friction coefficients of steel ropes. When the drive brake engages, for example during an emergency stop triggered by the safety circuit, slippage at the traction sheave is much lower with plastic-coated suspension elements than with steel cables. As a result, much higher deceleration values occur in and around the elevator car. With the inventive fixed point for the Tragmittelendverbindungen the ride comfort can be maintained even with modern support means in an emergency situation. Especially in the case of fast-moving elevators, a soft emergency stop must be ensured, too long delays would lead to accidents and injuries to the elevator passengers in the elevator car. The fixed point according to the invention is firmly connected to the guide rail or to the elevator shaft during normal operation. In an emergency stop triggered by the safety circuit, the fixed point is released by means of a mechanism whereby the mechanism and the drive brake are triggered simultaneously. However, the mechanism releases the fixed point before the braking torque generated by the drive brake is set up to decelerate the elevator car. With the build-up braking torque occurs a delay of the elevator car, wherein a damping element of the released fixed point springs in and attenuates the delay to a bearable for the elevator passengers Mass. The safety circuit monitors essential safety-related functions of the elevator and preferably comprises a series connection of contacts for Monitoring of, for example, door positions of the car door or the landing doors, for monitoring the speed of the elevator car, for monitoring the power supply for the elevator control, for monitoring the detection of the shaft end and so on. If one of the contacts of the safety circuit opens, as described above, an emergency stop is triggered and the drive brake is engaged and the fixed point is released.
