Definitions

  • the present invention relates to an elevator device, and in particular, to a guidance device (horizontal suspension) for moving an elevator car up and down along guide rails.
  • JP-A-5-319739 discloses a conventional elevator device in an example, which incorporates a vibration sensor provided to an elevator car for suppressing a vibration level of an elevator car chamber, and sensors provided in the upper and lower parts of the elevator car composed of the car chamber and a car frame, for detecting displacements of guide rails. Further, actuators which are provided in the lower part of the elevator car are feedback controlled with the use of detection signals from the sensors, and further, are feed-forward controlled with the use of signals from sensors for detecting displacements of the guide rails. Thus, the vibration of the elevator car is suppressed horizontally.

  • the current is applied to the coil so as to reduce the shake with the use of Lorentz's force in order to restrain disturbances caused by bending of the guide rails, and stepped parts in joints thereof.
  • sensors for detecting displacements of the guide rails are adapted to detect rail surfaces.
  • optical sensors are inappropriate if the surfaces of metal rails are glossy since it difficult to precisely detect a displacement by an optical sensor due to reflection upon the glossy rail surface.
  • sensors other than optical sensors be used, although the affection by the gloss could be avoided, they would be expensive or likely to be affected by damages and the like.
  • output signals from the sensors are used in feed-forward control, a displacement should be detected before the actuator passes by, and accordingly, the sensors must be attached to the positions remote from the car frame, which are remoter than the actuator. Thus, it is difficult to aim at saving a space.
  • JP 2001270668A discloses an installation accuracy measuring device and method for guide rails.
  • the device comprises a displacement gauge for a lifting body, a horizontal and a vertical accelerometer for said lifting body and a control calculating installation accuracy of the guide rail based on the detected results.
