Document Type and Number:
Japanese Patent JP2016104664
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an elevator emergency rescue operation device during power outage, capable of reducing power consumption of elevator emergency rescue operation.SOLUTION: A control device 17 of the invention comprises: a load calculation part 26E for, on the basis of a position of a car 3 detected by position detection devices 13, 26A, 26B, and a load in the car 3 detected by load detection devices 14, 26C, calculating a load on the car 3 side and a load of a balance weight 5 side applied to a motor 8, respectively; a direction calculation part 26F for comparing the load on the car 3 side and load on the balance weight 5 side of the motor 8 calculated by the load calculation part 26E, and calculating a rotation direction where driving force of the motor 8 becomes a light load; and a driving control part 26D for controlling drive of the motor 8 so that, the rotation direction of the motor 8 in emergency rescue operation of an elevator 1 becomes the rotation direction calculated by the direction calculation part 26F.SELECTED DRAWING: Figure 3
