Displacement-positioning positive and reverse rotation monitoring system

Abstract

The invention relates to the technical field of elevator safety design and relates to a displacement-positioning positive and reverse rotation monitoring system, comprising a power supply, an emergency stop controller, a motor, a harness, positioning moving members and positioning fixed members. All the power supply, the emergency stop controller and the motor are disposed below an escalator; escalator steps are driven by the motor to function. One positioning moving member is disposed below each escalator step. The positioning fixed members are disposed below the escalator steps. The lower end face of each positioning moving member is provided with irregular pits. In the invention, the positioning fixed members may judge positive and reverse operating directions of the escalator steps by monitoring changes of the lower pits of the positioning moving members, and when reverse operation of the escalator steps is monitored, the emergency stop controller controls the motor to stop operating in time. The system is reasonable in design, simple in structure and applicable to optimal designing of mitigation systems for escalator crowdedness or stampede accidents.

Description

Technical field [0001] The invention belongs to the technical field of elevator safety design. Specifically, it is a displacement positioning type forward and reverse monitoring system that can recognize crowding or trampling accidents of escalators through an infrared monitor. Background technique [0002] The elevator is a vertical elevator powered by a motor, equipped with a box-shaped pod, used for multi-storey buildings to carry people or carry goods. There is also a stepped type, the stepper is installed on the track to run continuously, commonly known as the escalator or moving walk. Fixed lifting equipment serving the specified floors. The vertical elevator has a car that runs between at least two rows of vertical or rigid guide rails with an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload cargo. It is customary to regard elevators as the general term for vertical transportation ve...

However, if the elevator maintenance is not in place, the escalator may have a stampede accident

By searching the existing patent technology, it is found that the application number is 201510329002, and the patent technology named as the method of preventing accidental movement of the elevator car provides a method to prevent the displacement of the elevator car, but it still does not propose how to reduce the displacement after the accident occurs.
