Problems solved by technology

As described in Patent Document 3 and Patent Document 4, if the active guidance device is stopped when an abnormality occurs, the vibration of the elevator car cannot be suppressed, and the ride comfort will deteriorate.
Whether stopping the elevator until the maintenance personnel arrives or stopping the active guidance and continuing the elevator, passengers feel uncomfortable

Embodiment 1

[0029] Hereinafter, the first embodiment of the present invention will be described. First, based on figure 2 as well as image 3 , a vibration damping system for actively suppressing lateral vibration of an elevator car caused by guide rail irregularities and the like will be described. exist figure 2 Among them, an elevator car 10 of an elevator device has a car frame 11 and a car chamber 12, and roller guide mechanisms 14, 15, 16, 17 as vibration damping mechanism parts are provided on the upper and lower parts of the car frame 11. The roller guide mechanisms 14, 15, 16, and 17 abut on guide rails (not shown) provided in the hoistway, and the elevator car 10 moves up and down along the guide rails. The roller guide mechanisms 14 , 15 , 16 , and 17 are provided on the left and right sides of the elevator car 10 and substantially in the center in the front-rear direction of the elevator car 10 . Then, the guide rails are attached and fixed to the hoistway wall surface so...

Abstract

The invention provides an elevator in which a damping device will not be stopped and the ride comfort is secured even if a failure occurs to any one of a plurality of acceleration detectors and a plurality of actuators constituting the damping device. The elevator has a pair of guide rails arranged in a vertical direction in a hoist trunk; an elevator car that ascends and descends along the guide rails; a plurality of acceleration detectors that detect vibration of the elevator car; and a control device that controls a plurality of actuators based on the output of the plurality of actuators for suppressing the vibration of the elevator car and the plurality of acceleration detectors, reproduces parameters for generating a control command transmitted to the plurality of actuators when any one of the plurality of acceleration detectors fails, and generates the control command transmitted to the plurality of actuators based on the value of normal acceleration detector in the plurality of acceleration detectors.

Description

technical field [0001] The present invention relates to an elevator in which vibration of an elevator car is suppressed by an actuator mounted on a roller guide. Background technique [0002] The elevator is provided with a guide device that moves the elevator car up and down along the guide rails and makes the rollers contact the guide rails from three directions. A total of four guide devices are installed on the upper, lower, left, and right sides of the elevator car, and the rollers are pressed against the guide rails, and the pressing force is adjusted by springs provided on the rods on which the rollers are attached. In addition, through the adjustment of the spring force, the vibration of the elevator car in the front, rear, left and right directions caused by the irregularity of the guide rail is suppressed. [0003] In addition, in order to simplify the structure, it is known, for example, as described in Patent Document 1: a single actuator is used to control the ...
