The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
Refer to Fig. 1 to Fig. 9, the utility model provides the anti-reverse detecting device of a kind of escalator or moving sidewalk, it comprise the metal sprocket wheel 1 being located in drive shaft and thering are a plurality of along the circumferential direction teeth spaced apart, be arranged on a side of metal sprocket wheel 1 and be fixed on escalator or the side truss 2 of moving sidewalk on probe bracket 3, be arranged on probe bracket 3 and respectively facing to two metal probes 4, the frock 5 of the side of adjacent two teeth 11,12 on metal sprocket wheel 1.Described anti-reverse detecting device also comprises and described two checking systems that metal probe is electrically connected mutually, and checking system is not utility model point of the present utility model, therefore not shown in the figures.
Between two metal probes 4 and the side of metal sprocket wheel 1, have gap, metal sprocket wheel 1 can rotate relative to metal probe 4.In the present embodiment, metal sprocket wheel 1 is metal duplex chain wheel.
Refer to Fig. 3 and Fig. 4, probe bracket 3 comprise fixing metal probe 4 attachment face 31, with the bearing surface axially paralleling 32 of metal sprocket wheel 1 and the joint face 33 being fixedly connected with side truss 2.On attachment face 31, have with metal sprocket wheel 1 on adjacent two teeth 11,12 one to one 311,312, two metal probes 4 of two mounting holes be fixedly mounted on correspondingly in two mounting holes 311,312.The week that the bearing surface 32 of probe bracket 3 is positioned at metal sprocket wheel 1 laterally.On the joint face 33 of probe bracket 3, offer a plurality of bar holes 331 for attaching screw.
Probe bracket 3 is directly installed on the side truss 2 of escalator or moving sidewalk, do not need by horizontal support, metal probe to be fixed on again the place ahead of metal sprocket wheel 1, make the structure of anti-reverse detecting device of the present utility model simpler, easier for installation.
When metal sprocket wheel 1 rotates, two metal probes 4 can send signal and survey tooth acquisition detection signal, the detection signal of two metal probes 4 of checking system reception is monitored the rotation direction of escalator or moving sidewalk, if while finding that metal sprocket wheel reverses, escalator or moving sidewalk are automatically out of service.
