膨胀节波形检测装置系统设计

摘要

It introduces the principles and methods of expansion joint detection device and completes the machine body of the device and control system design .It uses the move of sprocket on the arc -shaped rail to rotate the detector for measuring the waveform changes of the expansion joint , and applies the axial movement of screw to drive test head to measure the waveform changes of expansion joint , takes PLC in the control system for real -time control of the detection device .The system uses the computer to process the date detected by the device and display the image .%详细介绍了膨胀节检测装置设计的原理及方法,完成了该装置的机械主体及控制系统设计. 利用链轮在圆弧形导轨上的移动实现检测装置旋转测量膨胀节波形的径向变化,利用丝杠带动检测头轴向移动来测量膨胀节波形的轴向变化,采用PLC对检测装置进行实时控制,通过计算机处理数据和显示图形.
