Elevator landing door safety protection structure

Abstract

The invention discloses an elevator landing door safety protection structure. The elevator landing door safety protection structure comprises opposite open type door leaves, door pockets fixed to thetwo sides of the door leaves and a sill located below the door leaves. The sill is fixedly installed at the bottom of an opening of a shaft landing door, a plurality of limiting sliding block mechanisms are installed below the door leaves in a detachable mode, and upper clamping teeth are evenly arranged at the bottoms of the limiting sliding block mechanisms. A sliding groove is formed in the topend face of the sill in a concave mode, the limiting sliding block mechanisms are arranged in the sliding groove in a rolling mode, safety blocks are connected with the bottom of the sliding groove through lifting components, and lower clamping teeth clamped with the upper clamping teeth are arranged at the tops of the safety blocks. A contact type switch mechanism controlling the lifting components is installed on the outer surface of the sill. When an elevator door is not stopped on the floor where the landing door is located, a power supply circuit of a first electromagnet and a second electromagnet are in a connected state all the time, the upper clamping teeth of the limiting sliding block mechanisms and the lower clamping teeth on the sill are made to be clamped under the action ofelectromagnetic force, locking below the door leaves can be achieved, and it can be avoided that the door leaves are unauthorizedly opened in a man-made malice operation situation.

Description

technical field [0001] The invention relates to the technical field of elevator hall door safety protection equipment, in particular to an elevator hall door safety protection structure. Background technique [0002] As a characteristic equipment, the safety of elevators has always been the focus of people's attention, and it is also a topic that people in the industry are constantly discussing. The elevator hall door is the only barrier to isolate the hall and the shaft, and at the same time it is the only way to connect the car and the hall. The safety of the hall door is particularly important for the operation of the elevator system. [0003] There are many types of elevator accidents, which are generally divided into top rushing, squatting bottom, door accidents and other accidents. Among them, door accidents accounted for the largest proportion. The hall door accident is mainly due to the poor contact of the hall door interlock, which causes the hall door to open wit...

AI Technical Summary

Problems solved by technology

However, when the hallway is subjected to pulling forces from both sides, or when the door leaf is pried open, this device cannot protect the door lock mechanism above the hallway. For this reason, we propose a safety protection structure for the elevator hall door to solve the above-mentioned problems. question
