Abstract

The invention relates to an automatic emergency braking and warning device of an escalator and belongs to the technical field of lift braking. The automatic emergency braking and warning device comprises an automatic emergency braking device and a warning device. The automatic emergency braking device comprises a braking device power source, a braking device switch, a photosensitive resistor, a solenoid, an iron core, a laser light, and a transverter. The braking device power source, the braking device switch, the photosensitive resistor and the solenoid form a series circuit. The iron core islocated in the solenoid and the transverter is located under the iron core. The transverter is separated from the iron core during working and is in contact with the iron core during braking. The warning device comprises a warning light and an electric bell. The warning light is connected with the electric bell in series and is connected with the automatic emergency braking device in parallel. The automatic emergency braking and warning device of the escalator combines the principles of the photosensitive resistor and an electromagnet to conduct emergency braking on the escalator, is simple in structure, convenient to install, and has a wide application range; the condition that accidents happen to children at the two ends of the escalator is avoided, and the elevator can automatically brake and warn when accidents occur.

Description

technical field [0001] The invention belongs to the technical field of elevator brakes, and in particular relates to an automatic emergency brake and alarm device for a walking elevator. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. [0003] With the rapid economic development and the continuous deepening of the urbanization process, my country's elevator industry is experiencing a period of rapid development. my country's elevator production increased from 10,300 units in 1990 to 365,000 units in 2010, with a compound annual gro...
