の重大事故が発生する可能性が大きい。In the above-mentioned prior art, the limit switch mounting position is located at a certain distance from the regular floor level to the final limit switch side before the final limit switch and in order to prevent malfunction during regular floor landing. Need to be a place with. However, it is difficult to secure the mounting position of the limit switch in a low-speed elevator with a small top clearance, such as for general houses, or a pit clearance. Since it will be difficult to secure the emergency stop distance after passing through, there is a possibility that a passenger will be trapped due to the operation of the final limit switch, or a serious accident such as the car or the counterweight colliding with the shock absorber. large.

御など従来からの基本的な制御機能も含まれる。The detector 21 detects the operating condition of the limit switch 12 and the traveling distance of the elevator from the inside of the elevator tower 24, and detects the traveling distance and the traveling time from the time when the car reaches the operating point of the limit switch 12. The measurement is started and at the same time, the measured value is sent to the comparison unit 22. The comparison unit 22 compares the measured value with the set value, and when any of the measured values exceeds the set value due to an abnormality in the elevator, a traveling command cutoff signal is sent to the control unit 23. The control unit 23 limits the traveling of the elevator according to the instruction of the comparison unit 22 and prevents the car 11 from coming into contact with the final limit switch 13 and the shock absorber 14. The control unit 23 also includes a conventional basic control function such as normal deceleration control.

る。According to the present invention, the limit switch can be installed at a place where the car operates before reaching the landing position on the terminal floor. At this time, if the deceleration is normal, it does not affect the traveling of the elevator at all, and when the elevator is abnormal, the elevator is stopped before the final limit switch operation position and the car or the counterweight contact with the shock absorber. Since the distance can be secured, it is possible to prevent unnecessary accidents of trapping passengers. Also,
It has a function to reliably cut off the traveling command of the elevator even if the elevator passes through the landing position, such as the elevator continues traveling at a slight speed even after deceleration.
