Embodiment Construction

[0045] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0046] figure 1 It is a cross-sectional view showing the outline of an elevator controlled operation device according to an embodiment of the present invention. The elevator car 2 and the counterweight 3 in the elevator hoistway 1 are suspended by a main sling 5 wound on the hoist 4, and the main sling 5 drives the elevator car 2 and the counterweight 3 up and down. One end of a tail cable 6 used to supply power to the elevator car 2 and communicate with the outside of the elevator car is suspended at the lower part of the elevator car 2, and the other end of the tail cable 6 is fixed at a height equivalent to the middle floor On the wall of the lift channel. The tail cable 6 moves up and down as the elevator car 2 rises and falls. The governor rope 7 is wound between the governor 8 and the tension balance weight 9, and its two ends are fixed to the emergency stop device ...

Abstract

Provided is an elevator earthquake control operation apparatus, which can prevent the elevator from damage when the main suspender and the like long size members shakes due to the earthquake and contacts or wraps with the protrusion in the hoist trunk, simultaneously can more safely run to the nearest floor to prevent passengers from being closed in the elevator cage. The apparatus detects whether the long size members wrap in the moving direction of the elevator cage, if the problematical wrapping takes place, the elevator has emergency stop and the operation direction of the elevator is switched to an opposite direction, and then detects whether the long size members wrap in the moving direction of the elevator cage again, and simultaneously makes the elevator runs at low speed to the nearest floor.

Description

Technical field [0001] The present invention relates to an earthquake controlled operation device and an earthquake controlled operation method for stopping an elevator to the nearest floor when a predetermined shaking of a building due to an earthquake, strong wind, etc. is detected during elevator driving. Background technique [0002] Figure 4 It represents the flow of elevator control operation in the prior art. In the existing elevator control operation, after an earthquake occurs, the elevator control operation starts when the ultra-low-level seismic sensor operates. At this time, if the low-level seismic sensor is not operating and the elevator is running, the elevator car can be moved to the nearest floor and the elevator car can be parked on that floor, and after a certain period of time, the ultra-low The level of seismic sensor is reset to restore the elevator to normal operation. [0003] In addition, in the prior art, when the low-level seismic sensor is operating,...
