Definitions

  • a first setting speed generator 3 sets the speed to a speed higher than the operating speed at a car position based on the generated car operating speed pattern
  • a second setting speed generator 4 generates a speed that is set higher than the speed generated by the first setting speed generator 3
  • a third setting speed generator 5 generates a speed higher than the speed generated by the second setting speed generator 4.
  • FIG. 6 is a diagram showing the concept of the result generated by passing the waveforms 24 and 25 shown in FIGS. 3A and 3B through the filter 8a having the characteristics 26 shown in FIG. 5 .
  • a waveform 27 shown in FIG. 6A is the result generated by passing the waveform 24 shown in FIG. 3A through the filter 8a and, in this case, the vibration component is extracted.
  • a waveform 28 shown in FIG. 6B is the result generated by passing the waveform 25 shown in FIG. 3B through the filter 8a and, in this case, a little or no output is generated.

Claims (8)

  1. Aufzug, bei dem eine erste festgelegte Geschwindigkeit entsprechend einer Position einer Aufzugkabine (70) festgelegt ist, die vertikal entlang einer Führungsschiene (75) in einem Schacht sich bewegt und bei der eine zweite festgelegte Geschwindigkeit auf einen höheren Wert eingestellt ist als die erste festgelegte Geschwindigkeit, wobei eine erste Bremsvorrichtung (11) betätigt wird wenn die Geschwindigkeit der Kabine (70) größer wird als die erste festgelegte Geschwindigkeit und eine zweite Bremsvorrichtung (13) wird betätigt, wenn die Geschwindigkeit der Kabine (70) größer wird als die zweite festgelegte Geschwindigkeit, dadurch gekennzeichnet,dass der Aufzug ferner aufweist:
    eine dritte festgelegte Geschwindigkeit, die höher ist als die zweite festgelegte Geschwindigkeit; und
    einen Vibrationsdetektor (8), der eine Geschwindigkeitsänderung der Kabine (70) erfasst, wenn die Geschwindigkeit der Kabine 70) die erste festgelegte Geschwindigkeit überschreitet und die erste Bremsvorrichtung (11) betätigt wird, wobei die zweite Bremsvorrichtung (13) betätigt wird auf der Grundlage einer Änderung der Geschwindigkeit der Kabine (70) und auf der Grundlage der zweiten festgelegten Geschwindigkeit oder der dritten festgelegten Geschwindigkeit.
  2. Aufzug nach Anspruch 1, wobei der Vibrationsdetektor (8) aus einer Vibrationskomponente die Geschwindigkeitsänderung der Kabine (70) extrahiert.
  3. Aufzug nach Anspruch 1, wobei die zweite Bremsvorrichtung 13) betätigt wird wenn die Geschwindigkeitsänderung der Kabine (70) kleiner oder gleich einem Schwellenwert ist und die Geschwindigkeit der Kabine (70) die zweite festgelegte Geschwindigkeit überschreitet.
  4. Aufzug nach Anspruch 1, wobei der Vibrationsdetektor (8) aus einer Vibrationskomponente die Geschwindigkeitsänderung der Kabine (70) extrahiert und die zweite Bremsvorrichtung (13) betätigt wird wenn die Vibrationskomponente einen Schwellenwert überschreitet und zusätzlich die Geschwindigkeit der Kabine (70) die dritte festgelegte Geschwindigkeit überschreitet.
  5. Aufzug nach Anspruch 1, wobei der Vibrationsdetektor (8) die Beschleunigung als die Geschwindigkeitsänderung der Kabine (70) erfasst.
  6. Aufzug nach Anspruch 1, ferner aufweisend einen Puffer am Boden des Schachtes, wobei die dritte festgelegte Geschwindigkeit so festgesetzt ist, dass die Kabine (70) gestoppt werden kann ohne den Puffer zu berühren wenn die Geschwindigkeit der Kabine (70) die dritte festgelegte Geschwindigkeit überschreitet und die zweite Bremsvorrichtung (13) betätigt wird.
  7. Aufzug nach Anspruch 1, ferner aufweisend einen Puffer am Boden des Schachtes, wobei die zweite festgelegte Geschwindigkeit so festgesetzt ist, dass die Kabine (70) gestoppt werden kann ohne den Puffer zu berühren, wenn die erste Bremsvorrichtung (11) betätigt wird.
  8. Aufzug nach Anspruch 1, wobei der Vibrationsdetektor (8) die Änderung der Geschwindigkeit der Kabine (70) aus einer Vibrationskomponente extrahiert, wobei die zweite Bremsvorrichtung (13) betätigt wird wenn die Vibrationskomponente kleiner oder gleich einem Schwellenwert der Geschwindigkeit der Kabine (70) ist, der die zweite festgelegte Geschwindigkeit übersteigt und wobei die zweite Bremsvorrichtung (13) betätigt wird, wenn die Vibrationskomponente den Schwellenwert überschreitet und die Geschwindigkeit der Kabine (70) die dritte festgelegte Geschwindigkeit überschreitet.
