Abstract
The utility model 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 is simple in structure, can detect operation state of the escalator at any moment and can achieve the aim of finding an escalator reversion phenomenon in time.
Description
Technical field
The utility model 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 easily occurs.Need the running state of staircase is detected for this reason.
Summary of the invention
The utility model purpose is to provide 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 support.
The utility model adopts technique scheme, and compared with prior art have following advantage: two magnet proximity switch are fixed in driving chain hinge wheel one side, by detecting the blocking situation of sprocket, judges 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.The speed sense channel of two groups of mutual redundancies of magnet proximity switch conduct by setting certain pulse period or frequency threshold values, can detect respectively 1.2 times or 1.4 times of hypervelocities, and protect.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, Phase-Sequence Difference changes, and can judge that 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 utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model 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 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; Phase-Sequence Difference changes; can judge that staircase takes a turn for the worse, stop the staircase running by programming control additional brake (not looking out in 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 support (3).
