Abstract
The invention relates to a safety system realizing automatic stop of an escalator when a floor plate thereof is opened. The safety system comprises a touch switch and a regulating mechanism, wherein the touch switch is capable of forming a closed loop with an escalator control center, and the regulating mechanism is used for controlling on or off state of the touch switch. The regulating mechanism comprises a limit shaft, a support and an abutting part; the limit shaft is fixed on an escalator frame; the support is arranged on the limit shaft and capable of rotating clockwise or anticlockwise along the axis of the limit shaft; the abutting part is arranged on the support and used for controlling on or off of the touch switch; when the support is in a natural state, a height difference is generated between two ends of the support. Safety accidents can be prevented effectively by the safety system. In addition, the support of the safety system resets to the natural state only after the support is separated from the floor plate, so that accuracy of the safety system for the escalator is improved while cost is reduced.
