Elevator door safety protection device

Abstract

The invention discloses an elevator door safety protection device. The elevator door safety protection device comprises an elevator car door, a drive mechanism, a first transmission mechanism and a controller. The elevator car door is provided with a transmitter and a receiver. The elevator door safety protection device further comprises a second transmission mechanism connected with the drive mechanism. The transmitter and the receiver are in sliding connection with the elevator car door. The elevator car door is provided with sliding grooves. The transmitter and the receiver are in sliding connection with the sliding grooves through sliding blocks. The moving distance of the sliding grooves in the length direction of the elevator car door is larger than or equal to the distance between adjacent infrared transmitting pipes in the transmitter. Moving of the elevator car door, the transmitting end and the receiving end can be achieved only by using one drive mechanism, and a power source is saved; the sliding grooves are arranged in a sine curve manner, the sliding blocks can drive the transmitting end and the receiving end to move in the moving direction of the elevator car door and the length direction of the elevator car door, and the purpose of blind area eliminating is achieved; and a transparency detection sensor can detect transparent obstacles, the problem that infrared rays cannot detect the transparent obstacles is solved, and the elevator safety is improved.

Description

technical field [0001] The invention relates to the technical field of elevator safety protection, more specifically, it relates to an elevator door safety protection device. Background technique [0002] With the rapid development of urbanization, in urban housing construction, in order to occupy less land, many high-rise buildings have sprung up. Commercial office buildings, hotels, high-rise residential areas, etc. have become places where people go in and out. Elevators are also following These places are widely used, and a large number of people and goods are constantly conveyed by elevators, making them an indispensable tool for people to enter and exit these high-rise buildings. The automatic door of the elevator is automatically opened and closed under the control of the electric drive device. When the elevator door is in the process of closing, if a passenger enters or exits, there is a risk of being bumped or caught by the door. According to the provisions of 8.7....

AI Technical Summary

Problems solved by technology

However, due to the gap between the infrared emitting tubes, when the height of the small-sized object or obstacle does not exceed the gap, it cannot be detected, and there is a certain detection blind area, which makes the safety of the elevator not high.
