Elevator landing door with door plate interlocking device

Abstract

The invention discloses an elevator device, in particular to an elevator landing door with a door plate interlocking device. The elevator landing door with the door plate interlocking device comprises a pair of door plates, the tops of the door plates conduct interlocking through a door locking device capable of being opened and locked, the bottoms of the door plates conduct interlocking through the interlocking device capable of being opened and locked, and the opening and locking actions of the interlocking device and the door lock device are in linkage. By means of the elevator landing door with the door plate interlocking device, the technical problem that the door plates in an elevator has an anti-theft function is solved, after the elevator landing door with the door plate interlocking device is used in a specific elevator system, the situation that injuries and deaths are caused due to the fact that a passenger falls into a shaft carelessly from the elevator of landing can be effectively avoided, the use safety performance of the elevator system is remarkably improved, and the life and property safety of elevator taking personnel is effectively guaranteed.

Description

technical field [0001] The invention relates to an elevator landing door, in particular to an elevator landing door with a door panel interlocking device. Background technique [0002] As the level of social urbanization is getting higher and higher, and the process of urbanization is getting faster and faster, more and more high-rise buildings are rising. Elevators, as an indispensable modern transportation tool, are inseparable from people's life and work. However, with the continuous increase of the number of elevators in use, safety accidents related to elevators also occur from time to time, and the situation where passengers accidentally fall into the shaft from the elevator landing door of the landing and cause casualties occurs more frequently. [0003] However, the reason why passengers fall into the hoistway from the elevator landing door of the landing is that the main reason is that when the elevator car did not arrive at the landing, a pair of elevator landing d...

Problems solved by technology

However, with the continuous increase in the number of elevators in use, safety accidents related to elevators also occur from time to time, among which the situation of passengers accidentally falling into the shaft from the elevator landing door of the landing and causing casualties occurs more frequently

[0003] However, the reason why passengers fall into the hoistway from the elevator landing door of the landing is that the main reason is that when the elevator car did not arrive at the landing, a pair of elevator landing doors in the existing elevator landing door device is only Interlocking is performed through a set of door lock devices used to lock a pair of floor door hanging plates. If the wire rope connecting the two hanging plates breaks, the other hanging plate without a lock hook can move freely, and the elevator floor The door will be opened; considering that the longitudinal length of the elevator landing door is relatively long, the bottom of a pair of elevator landing doors of the above-mentioned interlocking structure is relatively easy to be opened by external force. The lock hook and the lock hook seat in the door lock device of a pair of landing door hanging plates may be disengaged from each other. Once the two are disengaged, the pair of elevator landing doors in the elevator landing door device can was opened at will
