Elevator landing door anti-collision device

Abstract

The invention discloses an elevator landing door anti-collision device, through which the problems of derailment, passenger falling and the like caused by deformation of the existing door planks are solved. The elevator landing door anti-collision device comprises a sill and a door plank which is assembled on the sill; and the technical key points are described as follows: the sill which is made of profiles is provided with a chute guiderail with an anti-falling baffle platform; the door plank is assembled on the sill through two groups of door plank sliders which are fixed on a lower end socket; each group of door plank sliders comprises two paired anti-falling sliders which consists of slider bodies and limit guide blocks wrapping the slider bodies; the slider bodies are combined and then fixedly connected with the door plank; the two limit guide blocks are combined and assembled in the chute guiderail with the anti-falling baffle platform of the sill; and under the driving of the door plank, the two limit guide blocks reciprocate along the length direction of the chute guiderail. The elevator landing door anti-collision device is simple in structure, reasonable in design, convenient for mounting and dismounting and safe and reliable for use, and has the advantages of enhancing the strength of landing doors, remarkably improving the tensile strength, abrasion resistance and anti-collision property of elevator landing doors, effectively avoiding deformation-caused derailment of door planks and eliminating the potential safety hazard of passenger falling.

Description

technical field [0001] The invention relates to a safety protection device for an elevator landing door, in particular to an elevator landing door anti-collision device used for preventing deformation of the elevator landing door when the door panel is hit by an abnormal external force. Background technique [0002] In order to solve the anti-collision problem of the elevator landing door composed of the sill and the door panel assembled on the sill when the door panel is hit by abnormal external force, many elevator manufacturers adopt the method of increasing the strength of the door panel to solve the problem. The fly in the ointment of this solution is that it not only increases the complexity of the door panel structure, but also increases the cost. Especially when the elevator landing door is subjected to external force, because the magnitude of the external force is not easy to control, the deformation of the door panel is not easy to grasp, so the structure of the re...
