Problems solved by technology

[0003] At this time, when the elevator is operated in the state where the rope is hooked to the equipment in the hoistway, it may cause damage to the equipment, and an incident may occur in which passengers are trapped in the car.
In addition, there may be an event that the recovery of the elevator takes a long time due to damage to the equipment
In addition, not only earthquakes, but also strong winds may cause the same event

Embodiment approach 1

[0026] figure 1 It is a block diagram showing the whole of the elevator according to Embodiment 1 of the present invention. Such as figure 1 As shown, the machine room 2 is set on the top of the hoistway 1. A traction machine 3 with a sheave, a deflector pulley 4 , a building sway detector 5 and an elevator control device 10 are arranged in the machine room 2 . The hoisting machine 3 and the deflector pulley 4 are arranged at intervals from each other.

[0027] Around the sheave and deflector pulley 4, there is a common main rope (for a long size part, such as a rope, a conveyor belt) 6. Hereinafter, the main rope 6 will be described as the rope 6 . The car 7 and the counterweight 8 are suspended from the ropes 6 . In this example, the upper part of the car 7 is connected to one end of the rope 6 , and the upper part of the counterweight 8 is connected to the other end of the rope 6 .

[0028] The sheave is rotated by the driving force of the traction machine 3 to move t...

Abstract

A control device and control method for elevators, which can prevent elevators from unnecessarily transferring to a control operation action in the situation of weak swaying of buildings, so that the service is improved. The control device for elevators includes: a calculation part (42) for calculating swaying quantity of a long size component (6) in the moment that a determination data value of swaying of buildings exceeds an operation reference value when a lift car is stopping; a comparison portion (32) for determining whether the swaying quantity of the long size component (6) exceeds a reference index value or not; a standard usual operation control portion (45) for performing an usual operation control on the lift car (7) when the swaying quantity of the long size component is less than the reference index value and the determination data value exceeds the operation reference value, and the standard usual operation control portion for automatically calling landing and registering to allow the lift car (7) to drive to change a stop position when the lift car cannot move over a preset time.

Description

technical field [0001] The present invention relates to an elevator control device and an elevator control method for controlling the operation of the elevator based on the amount of rope sway. Background technique [0002] In recent years, it has been reported that during long-period earthquake vibrations, the ropes in the elevator vibrate greatly due to the resonance with the swing of the building, and the equipment in the hoistway (for example, the flat surface installed on the inner wall of the hoistway) The mounting arm of the layer detection board) has the effect of hooking. [0003] At this time, when the elevator is operated in a state where the ropes are hooked to the equipment in the hoistway, the equipment may be damaged, and passengers may be trapped in the car. In addition, there is a possibility that the recovery of the elevator takes a long time due to damage to the equipment. In addition, not only earthquakes, but also strong winds may cause the same event....
