Problems solved by technology

[0002] With the development of society, the application of elevators is becoming more and more extensive, and the number of old elevators is also increasing. The quality of elevator maintenance is uneven, and elevator accidents also occur from time to time, especially falling casualties caused by abnormal opening of elevator landing doors. Accidents, the failure of the elevator brake to cause the shearing accident of the elevator, which accounts for a high proportion of elevator accidents, seriously threatens the personal safety of the elevator personnel
[0003] Elevator passengers are accustomed to standing at the door of the elevator floor, stepping in as soon as the door is opened, and when they find that the elevator car is not in place or the car is moving and cannot respond, elevator safety accidents occur

Embodiment

[0014] Embodiment: a kind of elevator near floor door safety warning device, such as figure 1 As shown, a door interlock switch (1) is included, and the door interlock switch (1) is sequentially connected with a distance sensor (2), a controller (3), and an audible and visual alarm device (4).

[0015] Working principle: The door interlock switch (1) is installed on both sides of the door, the elevator landing door is closed, the door interlock switch (1) is turned on, and the distance sensor (2) starts to work. The number of distance sensors (2) is more than one. Installed on the landing door of the elevator, the probe of the distance sensor (2) faces the waiting hall for sending and receiving signals, and the controller (3) processes the signal to calculate the distance between the passenger and the landing door of the elevator. When the distance sensor (2) detects that the distance of the passengers waiting for the elevator exceeds the distance set by the system, the system...

Abstract

The invention discloses an elevator near-floor door safety early warning device, which is composed of a door interlock switch (1), a distance sensor (2), a controller (3) and an audible and visual alarm device (4). The quantity of distance sensor (2) is more than one, is installed on the landing door of elevator, controls sound and light alarm device (4) to work by controller (3). The invention is simple in structure and easy to install. When the passenger is too close to the elevator landing door, an alarm can be issued to remind the elevator passenger to keep a certain safe distance from the elevator landing door, which can effectively prevent the accidental opening of the elevator landing door. Casualty accidents caused by elevator slipping.

Description

technical field [0001] The invention relates to a safety early warning device, in particular to an elevator near-floor door early warning device for safely riding an elevator Background technique [0002] With the development of society, the application of elevators is becoming more and more extensive, and the number of old elevators is also increasing. The quality of elevator maintenance is uneven, and elevator accidents also occur from time to time, especially falling casualties caused by abnormal opening of elevator landing doors. Accidents, the failure of the elevator brake to cause the shearing accident of the ladder, accounts for a high proportion of elevator accidents, and seriously threatens the personal safety of the elevator personnel. [0003] Elevator passengers are used to standing at the door of the elevator floor, step in as soon as the door is opened, and find that the elevator car is not in place or the car is no longer able to respond to the movement of the...
