On the fire door of dynamic heating furnace when lower switch, carriage and reflection unit 9 is driven to move up and down simultaneously also by mobile pull rod 3,
When reflection unit 9 is by displacement sensor 10, displacement sensor 10 is back to host computer by signal is detected.
Due to the weight and snap action of fire door itself, the shaking of oven door body and transmission chain is caused, in the band of transmission chain
Under dynamic, mobile pull rod 3 any direction in annulus 2 shakes, and shakes the impact force brought for offsetting oven door body, avoids reflecting
Device 9 shakes damage displacement sensor 10.
It is buting iron that institute's displacement sensors 10, which are close to reflection unit 9 when switch,；When displacement sensor 10 is magnetic switch
Reflection unit 9 is magnet；Reflection unit 9 is reflector plate when displacement sensor 10 is optoelectronic switch.
The upper plate and the steel plate that lower plate is thickness 10mm to 15mm, the holder are channel steel.
The advantage of the invention is that：Can be applied to the Compaction of Heating Furnace Door of existing chain drive or V belt translation, without pair
Oven door body and the kind of drive are transformed, you can effectively improve the accuracy and reliability of fire door position detection.Driving chain
Activity links between carriage, and the shaking of oven door body and driving chain does not influence reflection unit.Displacement sensor
Position is fixed between reflection unit, is not in the case where reflection unit shakes damage displacement sensor.
