1. detecting device that is used for magnet stopper;

  • Through with restoring force brake plate is urged based on the elastic deformation of retarding spring generate braking force on the parts that are being used to brake during;

    Drive said brake plate away from the said parts that are used to brake by means of the said restoring force that overcomes said retarding spring through the electromagnetic attraction that solenoidal excitation produced, thereby discharge braking force;

    Said detecting device comprises;

    Load transducer, it detects the said restoring force of said retarding spring;

    AndJudgment means, it confirms the state of said magnet stopper based on the output of said load transducer;

    Wherein said judgment means confirms based on the output of said load transducer whether the said braking force of said magnet stopper is lower than the normal judgement lower limit of regulation or is higher than the normal judgement upper limit of regulation;

    And;

    Be lower than the normal judgement lower limit of regulation or be higher than the normal judgement upper limit of regulation if find the said braking force of said magnet stopper, then output detection signal.
