ELEVATOR ROPE SLIP DETECTOR AND ELEVATOR SYSTEM |
摘要 |
<p>In an elevator apparatus, a pulley is provided in a hoistway. A rope that moves together with the movement of a car is wound around the pulley. Further, the pulley is provided with a pulley sensor for generating a signal according to the rotation of the pulley. The car is provided with a car speed sensor for directly detecting the speed of the car. A control panel is provided with: a first speed detecting portion for obtaining the speed of the car based on information from the pulley sensor; a second car speed detecting portion for obtaining the speed of the car based on information from the car speed sensor; and a determination portion for determining the presence/absence of slippage between the rope and the pulley by comparing the speeds of the car as respectively obtained by the first and second speed detecting portions.</p> |
