Description
Technical field
The present invention relates to a kind of pipeline online in real time ultrasonic thickness measurement device, particularly a kind of multiple caliber conduit online real-time ultrasonic thick measuring device.
Background technology
Pipeline not only can bring difficulty to installation if tube outer diameter and wall thickness are overproof, and can cause serious waste of material after machine-shaping.Wall thickness off-centre is overproof will to influence tubing compressive resistance and safety in utilization.So the on-line measurement and the control of the eccentric size of external diameter and wall thickness are crucial.China's pipeline former makes that the extruded product dimensional accuracy of producing is low owing to lack accurate measurement control device and equipment at present, the rejection rate height, and evenness of wall thickness is poor, thereby causes raw-material significant wastage.One of existing solution is to adopt ultrasonic pulse echo method to measure, promptly utilize ultrasonic probe that pipe wall is sent a ultrasonic pulse, successively receive pulsating wave by outer surface of tube wall and inside surface reflected back, distance values between these two pulsating waves has just reflected the thickness information of tube wall, then can obtain the actual value of pipe thickness more as calculated.Utilize the ultrasonic thickness measurement device of this method development, as European patent EP 0985905 described a kind of pick-up unit, the probe dish that comprises ultrasonic probe, water spraying mechanism and concentric, the weak point of this device are probe and water spraying mechanism stationkeeping, can only measure the fixedly pipeline of caliber.
Summary of the invention
