Abstract
The invention provides an anti-reversion detection device of an escalator and relates to the technical field of the escalator. Two groups of magnetic approach switches are arranged at one side of a large chain wheel of a driving chain; and the magnetic approach switches are arranged on a bracket. The anti-reversion detection device of the escalator has a simple structure, can detect the operation state of the escalator at any moment and can realize the aim of finding an escalator reversion phenomenon in time.
Description
Technical field
The present invention relates to the technical field of escalator.
Background technology
Along with greatly developing of city, escalator can be used in a lot of places.But escalator in use, thereby may cause for some reason chain rupture the phenomenon that reverses to occur, and, staircase running velocity excessive such as the pressure that a side is subject to is too fast etc., if having the pedestrian in the above this moment, accident occurs easily.Need the running state of staircase is detected for this reason.
Summary of the invention
The object of the invention provides a kind of simple in structure, detects the running state of staircase constantly, finds that in time staircase reverses the escalator anti-reverse detecting device of phenomenon.
A kind of escalator anti-reverse detecting device, a side of driving chain hinge wheel is arranged two groups of magnet proximity switch, magnet proximity switch is arranged on the support.
The present invention adopts technique scheme, compared with prior art has following advantage: two magnet proximity switch are fixed in driving chain hinge wheel one side, by detecting the blocking situation of sprocket, judge the real-world operation speed on staircase or footway.When escalator or moving sidewalk operation, every through a sprocket, all can interdict magnet proximity switch one time, send pulsatile once.By the pulse interval of detecting sensor, can calculate the speed of movable parts, further can calculate the running velocity on footway.Two groups of magnet proximity switch, can detect respectively 1.2 times or 1.4 times of hypervelocities, and protect by setting certain pulse period or frequency threshold values as mutually redundant speed sense channel.By the Phase-Sequence Difference of two approach switch signals, can judge the service direction of staircase, if staircase takes a turn for the worse, then Phase-Sequence Difference changes, and can judge that then staircase takes a turn for the worse, stops the staircase running by the programming control additional brake, plays a protective role.Simple in structure, the moment is detected the running state of staircase, can in time find and avoid staircase to reverse phenomenon.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated:
As shown in Figure 1, a kind of escalator anti-reverse detecting device, a side of driving chain hinge wheel 1 is arranged two groups of magnet proximity switch 2, magnet proximity switch 2 is arranged on the support 3.
Two magnet proximity switch are fixed in driving chain hinge wheel one side, by detecting the blocking situation of sprocket, judge the real-world operation speed on staircase or footway.When escalator or moving sidewalk operation, every through a sprocket, all can interdict magnet proximity switch one time, send pulsatile once.By the Phase-Sequence Difference of two approach switch signals, can judge the service direction of staircase, if staircase takes a turn for the worse; then Phase-Sequence Difference changes; can judge that then staircase takes a turn for the worse, stop the staircase running by programming control additional brake (not looking out among the figure), play a protective role.
Claims (1)
1. an escalator anti-reverse detecting device is characterized in that a side of driving chain hinge wheel (1) is arranged two groups of magnet proximity switch (2), and magnet proximity switch (2) is arranged on the support (3).
