Description of the drawings
Attached drawing 1 is the utility model structure diagram, and attached drawing 2 is to slide magnet ring scheme of installation, and attached drawing 3 is the present apparatus
Control block diagram, wherein 1 is hydraulic cylinder to be measured, 2 be piston rod, and 3 be connecting rod, and 4 be mounting bracket, and 5 be to slide magnet ring, and 6 be to survey
Bar, 7 be measurement geometrical clamp, and 8 be bearing, and 9 be sensor electronic storehouse.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is illustrated.The utility model discloses one kind
Coke oven commutation hydraulic cylinder measuring device, the measuring device include the connecting rod 3 being connected with hydraulic cylinder piston rod 2 to be measured, the device
It further includes：The mounting bracket 4 being fixed on hydraulic cylinder to be measured；Sensor, sensor are magnetostrictive displacement sensor, and mangneto is stretched
The displacement sensor that condenses includes sensor electronic storehouse 9, measuring staff 6 and slides magnet ring sensing element, slides magnet ring sensing element and is located at peace
It is connected on dress stent 4 and with connecting rod 3.The power supply and analog output of sensor are connected to smart display controller, intelligence
The output of display controller passes through physical location program that in cable connection PLC/DCS systems, PLC/DCS systems pass through hydraulic cylinder
It is compared, determines left limit, middle /V and the right limit of hydraulic cylinder respectively, interchanger is finally supplied with the output form of switching value
The program that commutates reads application.
In the present embodiment, sliding magnet ring sensing element includes sliding magnet ring 5, slides magnet ring 5 and is connected by measuring geometrical clamp 7
In on bearing 8, bearing 8 is flexibly connected with mounting bracket 4, and one end of bearing 8 is fixedly connected with connecting rod 3.In this way, slide magnet ring
Sensing element opposite mounting bracket 4 can generate relative displacement under the drive of connecting rod 3, and the displacement is by sliding magnet ring 5 and surveying
