Abstract

PURPOSE:To permit preparation work to be performed in a short time further easily for detecting action of a governor by providing the first and second switches, respectively detecting each action of the first and second levers, to be opposed facing to each lever. CONSTITUTION:When a riding cage obtains its lowering speed abnormal exceeding a predetermined value, a rotary speed is increased of a pulley 4 following this increase, when pendulums are spread to the outer of a circumference larger than normal, a protruding part 5a or 6a engages with an engaging part 10c of the first lever 10. In this way, the first lever 10 is turned in the clockwise direction, separating its point end from a safety switch 11 outputting a stop signal of the riding cage while the second arm 10b from the first switch 21 detecting action of the safety switch by this separation. When the riding cage further lowers at a fast speed, the protruding parts 5a, 6a are engaged with a pawl 13b of the second lever 13. In this way, the second lever 13 is turned in the counterclockwise direction with a shaft 12 serving as the center, separating the first arm 13a of the lever 13 from the second switch 22 detecting action of a weight 15.

Generally, in an elevator, a speed governor is installed in a machine room formed above the elevator path to detect whether the elevator speed of a passenger compartment reaches an abnormal speed exceeding a predetermined speed. This speed governor is capable of engaging a pulley around which a governor rope connected to a car is wound, and a pendulum that expands outward due to centrifugal force depending on the rotational speed of the pulley. It includes a first lever that engages with a safety switch, and a second lever that has a hook that can be engaged with and detached from a catch weight that can hold a governor rope. For example, when the car descends at an abnormal speed,
The pulley rotates faster than a predetermined rotational speed, and the pendulum expands toward the outside of the circumference, and this pendulum engages the first lever, which rotates the first lever and secures it. The switch operates and outputs a stop signal to the corner. Furthermore, as the car descends at a faster rate, the rotational speed of the pulley increases, causing the pendulum to spread further outward and engage the second lever. Correspondingly, the second lever rotates, the hook and the catch weight are released from each other, and the catch weight rotates to clamp the governor rope between it and the fixed body. When the governor rope is captured by the speed governor in this manner, a stop device provided on the car is activated to stop the car.
