Embodiment Construction

[0010] The present invention will be further described below with reference to the accompanying drawings.

[0011] On one side of the rotating part 1 of the escalator or moving walkway, eight magnetic induction elements with the same polarity direction—small magnetic steel 2 are evenly embedded. The Hall proximity switch sensor element A1, A2 Hall proximity switch displacement sensor 3, the Hall proximity switch displacement sensor 3 is connected with the escalator control microprocessor 4, and the escalator control microprocessor 4 is connected with the braking and power control device 5 is connected. The above-mentioned main engine rotating part 1 may be a main engine flywheel or a main engine sprocket or a driving wheel.

[0012] The working principle of the above device is: when the escalator or moving walk is working, the rotating part 1 of the main engine rotates at a certain speed, and whenever the magnetic steel 2 on the rotating part passes in front of the Hall proxi...

Abstract

A protecting unit for the uncontrolled reverse running and over-speed of escalator or automatic sidewalk is composed of escalator control microprocessor and its signal sensor unit, brake controller and power supply controller. Said signal sensor unit consists of parallel two non-contact shift sensor and the inducing parts on the moving part of host.

Description

technical field [0001] The invention relates to an operation safety control device of an escalator or a moving sidewalk, especially a non-operating reversing and overspeed protection device. Background technique [0002] According to safety regulations, escalators or moving walks must be equipped with overspeed and non-manipulated reverse protection devices. The existing non-manipulation reverse protection device is mainly composed of a transmission friction wheel, a rotary encoder, a PLC microprocessor, a transmission brake and a power supply control device. The transmission friction wheel is connected with the driving shaft of the escalator and drives the rotary encoder to rotate, and the rotary encoder transmits the rotation direction signal to the PLC. When the PLC receives the reverse signal during work, it sends a control signal to the transmission brake and power control device after processing to cut off the power supply and brake the transm...
