Embodiment 1

[0016] Such as figure 1 The illustrated embodiment one elevator door use detection safety system includes a sill chute 1, a floor door leaf 2 cooperating with the sill chute 1, a door slider 3 arranged at the bottom of the floor door leaf, and a door slider 3 arranged on the sill chute. An active infrared detector (not shown) and a control box (not shown) for processing the signal of the active infrared detector and connected to the elevator main controller, and the active infrared detector is connected to the control box. The floor door leaf 2 slides in the sill chute 1 through the door slider 3; when the floor door leaf is closed, the position of the active infrared detector and the position of the door slider 3 cooperate with each other.

[0017] There is a one-to-one correspondence between the number of door sliders and the number of active infrared detectors, and the number of active infrared detectors in this embodiment is four. In this embodiment, four active infrared ...

Embodiment 2

[0020] As shown in Table 1, the elevator door usage detection safety method in Embodiment 2 adopts the elevator door usage detection safety system shown in Embodiment 1. When the floor door is closed, if the active infrared detectors of the first infrared detection point A, the second infrared detection point B, the third infrared detection point C and the fourth infrared detection point D detect the door The slider sends an ON signal to the control box, and if the door slider is not detected, it sends an OFF signal to the control box. If the control box receives the ON signal of the four active infrared detectors, the signal output point of the control box sends an ON signal, and the elevator runs normally. If the control box does not receive the ON signal sent by the four active infrared detectors to the main controller of the elevator, the signal output point of the control box will send an OFF signal, and the elevator will stop running.

Abstract

The invention discloses a use detection safety system and method for an elevator door. The use detection safety system for the elevator door comprises a sill sliding groove, a storey door leaf matched with the sill sliding groove, a door sliding block arranged at the bottom of the storey door leaf, an initiative infrared detector arranged on the sill sliding groove, and a control box used for processing signals of the initiative infrared detector. The initiative infrared detector is connected with the control box. The storey door leaf slides in the sill sliding groove through the door sliding block. When the storey door leaf is closed, the position of the initiative infrared detector and the position of the door sliding block are matched. By the adoption of the above structure, automatic detection is achieved, the detection precision can be improved, effective detection is achieved, potential safety hazards are eliminated, and the workload of maintenance personnel is reduced.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator door use detection safety system and method. Background technique [0002] The lower part of the door leaf of the current elevator floor is usually fixed in the sill chute with two door sliders. When the door slider is lost or embedded in the sill chute depth is not up to the standard, it is easy to cause the lower part of the floor door leaf to be unable to be fixed. Under the impact of external force, it will break away from the sill chute (that is, displacement), causing the accident of people falling into the hoistway. possibility. The door slider can only be maintained through regular maintenance to ensure whether it is lost, or manually judge whether the embedded depth is up to standard, which has human subjective factors and potential safety hazards. Contents of the invention [0003] The object of the present invention is to disclose an elevator door use...
