Abstract
The invention discloses an elevator system capable of controlling a traction machine to stop running after counter-weight collapse to the bottom of a pit. A counter-weight rope head rod is arranged on a counter-weight rope head beam in a sliding penetrating manner; a pressure spring sleeves the upper part, which extends out of the counter-weight rope head beam, of the counter-weight rope head rod; the upper end of the pressure spring is in roof pressing fit with a limiting piece on the counter-weight rope head rod; a contact switch is fixedly arranged on one side of the counter-weight rope head rod on the counter-weight rope head beam; the contact of the contact switch is downward; a switch impact plate which is in contact with the contact after the counter-weight rope head rod moves upwards under the action of the pressure spring is fixed on the counter-weight rope head rod. According to the elevator system, the contact switch is arranged on one side of the counter-weight rope head rod, and the switch impact plate is arranged on the counter-weight rope head rod; after the elevator is subjected to counter-weight collapse to the bottom of the pit, the down pulling force of a steel wire rope on the counter-weight rope head rod disappears; under the action of the pressure spring, the counter-weight rope head rod moves upwards, and the impact plate is in contact with the contact of the contact switch to make the contact switch operate; therefore, the counter-weight collapse to the bottom of the pit can be accurately judged, to control the traction machine to stop running, and the elevator system meets the requirements of the national standard.
