The invention provides an early-warning device for abnormal opening of an elevator landing door. The early-warning device comprises a beacon transmitter and a beacon receiving early-warning device; the beacon transmitter is arranged in a lift car; the beacon receiving early-warning device is arranged on a landing door frame; the beacon transmitter is a short-distance signal sending mechanism and is in signal connection with the beacon receiving early-warning device when the lift car and the landing door frame are horizontally opposite within a settable range. According to the early-warning device for the abnormal opening of the elevator landing door, the technical problem of the early-warning prompt of the abnormal opening of the landing door is solved due to the combination of the structures and accordingly the good effects that the installation is easy, the production is easy, the early-warning prompt is implemented, and the safety hidden trouble is eliminated are achieved.
Description
technical field [0001] The invention provides an elevator early warning mechanism, in particular to an early warning device for abnormal opening of elevator hall doors. Background technique [0002] In the prior art, it is generally only detected for the safety of the elevator operating conditions, such as the mechanical failure of the elevator, or an alarm is issued when leveling, squatting, rushing to the top, and people are trapped in the car, that is to say, for the elevator. The important parameters of the operation are monitored and alarmed. However, for the abnormal opening of the elevator hall door, such as figure 1 with figure 2 As shown, the abnormal opening of the hall door 20 is relative to the normal opening of the hall door 20, that is to say: the stopped / suspended car 10 and the hall door 20 should be kept "horizontally opposite" (that is, the bottom of the car 10 The plane 12 and the lower plane 22 of the hall door 20 are kept on the same horizontal line) ...
