Abstract

The invention discloses an elevator landing door lock protective device and an elevator landing door. The elevator landing door lock protective device comprises a mainframe, a first sensor, a second sensor, and an electric magnetic mechanism, wherein the first sensor and the second sensor are separately mounted at upper and lower ends of the elevator landing door for detecting the position of an elevator car, and transmitting a detected signal to the mainframe; the electric magnetic mechanism is arranged on a landing door lock, and is used for receiving a control signal transmitted by the mainframe and realizing opening or closing of the landing door lock according to the control signal; while the elevator is in a normal operation state, the device can achieve the protective effect on thelanding door lock, so that the landing door lock can be ensured to be opened while the elevator car is on a set position; and the landing door lock cannot be opened while the elevator is on an unset position. Safety of rescue, maintenance or staff in the car is ensured.

Description

Technical field [0001] The invention relates to the technical field of special equipment elevator safety, in particular to an elevator floor door lock protection device and a floor door lock. Background technique [0002] The elevator is a kind of equipment that moves vertically between different floors in the hoistway. Each landing of the elevator is equipped with a landing door. The landing door drives the opening of the car door to allow passengers to enter and exit the car. When the elevator is running and the car is not in the leveling position, the floor car doors are all closed to prevent accidents. At the same time, in order to prevent the passengers in the car from opening the car door manually, a door lock is installed on the car door. When the car reaches the leveling position, the car door opens and the elevator door lock circuit is disconnected. The elevator stops running and cannot Start to ensure the safety of passengers. When the elevator is in a power outage, r...
