Problems solved by technology

However, in an elevator with a high-speed car, the kinetic energy of the entire system is large, so the sliding distance of the friction member increases during emergency braking.
Therefore, there is a problem of increased wear of the friction parts and reduced braking capacity, and there is a need to prevent the elevator from continuing to run in a state where the braking capacity is reduced.

Abstract

The invention provides a control device of an elevator device, and an elevator device thereof. The control device of the elevator device suppresses wearing increase of a vibration component caused by repeated emergency stopping in high-speed operation and prevents braking capability reduction caused by wearing increase, thereby obtaining a stable brake force. The control device of the elevator device applies an action signal on a braking device of the elevator device, wherein the elevator device is provided with a traction machine for lifting an elevator cage and the braking device which applies a braking force on the traction machine. The control device comprises the components of an abnormity detecting part which detects abnormity of the elevator device; an action control part which applies an emergency braking force on the traction machine by means of the braking device when the abnormity of the elevator device is detected; and a meter for storing a reference number of the cage speed and a reference number of braking times. When the abnormity detecting part detects a fact that the cage speed is higher than the reference number of the cage speed when the abnormity is detected, an emergency braking force is applied on the traction machine by means of the braking device; and when the accumulated number of the number-of-times of emergency braking force application is higher than the reference number of braking times, the cage speed is suppressed.

Description

technical field [0001] The present invention relates to a control device for an elevator device and the elevator device, and more particularly to a control device for an elevator device that performs an emergency stop operation stably and reliably by using a brake device provided on a hoisting machine, and an elevator device equipped with the same. Background technique [0002] As a brake device for a traction machine installed in an elevator device, there is known a structure in which a friction member is pressed against a body to be braked to perform braking. Generally, when an abnormality is detected, the control device is operated to decelerate the elevator device. . However, in an elevator whose car runs at a high speed, since the kinetic energy of the entire system is large, the sliding distance of the friction member increases during emergency braking. Therefore, there is a problem that the wear of the friction member is increased and the braking ability is reduced, ...
