Description

  The present invention relates to an elevator control device that mainly suppresses a decrease in elevator operation rate due to door opening / closing abnormalities.

  Conventionally, an elevator is moved up and down by a hoisting machine and a rope, and includes a car door provided on a car and a landing door provided at each landing.

  Among these, the elevator car door is provided with a guide (guide shoe) at the lower part of the door panel, and is opened and closed along the car sill groove by a door drive mechanism and a door motor. On the other hand, the landing door engages with the car door and opens and closes, and the guide shoe moves along the landing sill groove.

  The car sill groove and the landing sill groove are generally about 10 mm wide. The landing sill and the car sill are almost the same height as the floor of the building and the floor of the car, so that foreign objects such as pebbles and garbage may enter the car sill groove or the landing sill groove. If the foreign object is sufficiently small relative to the car sill groove or the landing sill groove, the movement of the door is unlikely to be hindered, but the foreign matter that has fallen into the car sill groove or the landing sill groove gets caught in the car sill groove or the landing sill groove. Then, the guide shoe may be caught by a foreign object and the door cannot be opened or closed. During that time, the elevator was out of order, and the elevator could not be used until the elevator inspector removed the cause of the failure and restored it, causing the operating rate to decrease.

  As described above, among the causes of the failure of the elevator, even a minor failure that can easily remove the cause of the failure may cause the elevator to stop and the service to deteriorate.
