Problems solved by technology

For example, cracks invisible to the naked eye on the steps of an escalator will break during operation or the steps will be missing during operation; if the maintenance management personnel do not operate according to the regulations, the steps of the stopped escalator are lost before the start of the escalator, and the personnel do not perform operation checks before and after starting the escalator , or start the escalator without reinstalling the steps after repairing, etc., resulting in a high proportion of step failures in escalator accidents

Embodiment 1

[0007] Embodiment 1: see figure 1 , figure 2 , the detection module 6 of the present invention is connected in the safety loop of the escalator control cabinet 7 . The movable contact 5 refers to the common electrode 2 and the dedicated electrode 3 . At the two ends of the escalator steps 1 on the escalator frame 4 (how many special electrodes 3 are used for how many steps the escalator has, now take 7 escalator steps as an example), movable contacts 5 are installed, one of which is public electrode 2, and the other is the dedicated electrode 3 for this step.

[0008] The output detection signal unit 9 in the present invention is connected to the common electrode 2, and the receiving detection signal unit 10 is connected to the dedicated electrode 3 of each step, and the common electrode 2 and the dedicated electrode 3 interfere with both ends of the escalator step 1. The detection module 6 of the present invention is composed of a control unit 8 , a detection signal outpu...

Abstract

The invention relates to a safety detecting facility, and particularly to an escalator safety detecting device. The escalator safety detecting device comprises an escalator control cabinet, and is characterized in that a detecting module is connected with the escalator control cabinet. As the technical scheme is adopted, safety hazard of the escalator caused by stair fault is controlled efficiently, and personal safety of passengers is guaranteed.

Description

technical field [0001] The invention relates to a safety maintenance facility, in particular to an escalator safety detection device. Background technique [0002] With the development of escalator technology, the application of escalators is becoming more and more extensive, and various accidents on escalators are also increasing. For example, cracks invisible to the naked eye on the steps of an escalator will break during operation or the steps will be missing during operation; if the maintenance management personnel do not operate according to the regulations, the steps of the stopped escalator are lost before the start of the escalator, and the personnel do not perform operation checks before and after starting the escalator , or start the escalator after repairing and forgetting to restore the installation steps, etc., resulting in a high proportion of step failures in escalator accidents. Contents of the invention [0003] The technical problem to be solved by the p...
