A kind of oil tubing thread detection device based on PLC control

At present, the traditional oil tubing thread detection method exists in the measurement error, low efficiency, workload and other problems, for the traditional oil tubing thread detection problems in this paper puts forward an oil tubing thread detection device. The device consists of mechanical system, electrical system and control system, through the construction of mechanical equipment to achieve the lifting, positioning, clamping, rotating and imaging functions of the oil tubing, completed the wiring between the PLC and the various drive equipment, the use of Visual Studio to write the form program and Smart200PLC for linkage control. The results show that the linkage control of the oil tubing thread detection device has achieved good results, realizing the lifting and speed regulation of the linear actuator in the device and the start/stop control and speed regulation of the main motor, which is of great practical significance in realizing the automation, intellectualize and precision of the oil tubing thread detection.
