活动装置位移的测量方法及应用该方法的粗轧机和铡刀剪
摘要：
本发明公开了一种活动装置的位移测量方法及应用该方法的粗轧机和铡刀剪，通过提供拉线编码器和PLC系统，将所述拉线编码器安装在活动装置的固定端，将拉线编码器的拉线固定在活动装置的活动端，使拉线随着所述活动端移动；当拉线随着活动端移动时，拉线编码器产生信号的变化；通过PLC系统的信号模板采集信号的变化量，经过计算得到活动端的位移变化。该方法有效克服了因为机械间隙而导致的位置测量误差。所述粗轧机应用该方法后可实现侧导板宽度的精确测量，减少轧制过程中的镰刀弯现象，提高产品质量。所述铡刀剪应用该方法后，提高了钢板宽度的测量精度。
摘要（英）：

The invention discloses a movable device displacement measurement method as well as a rough mill and a gate footstep shear using the same. According to the measurement method, a stay wire coder and aPLC system are provided; the stay wire coder is installed at the fixed end of a movable device; a stay wire of the stay wire coder is fixed to the movable end of the movable device so that the stay wire moves with the movable end; when the stay wire moves with the movable end, the stay wire coder is used for generating signal changes; a signal template of the PLC system is used for acquiring the variation of signals; and displacement changes of the movable end are obtained by calculation. The method effectively overcomes position measurement errors caused by mechanical clearances. After usingthe method, the rough mill can realize precise measurement of the width of a side guide plate, reduces the phenomenon of cambering generated in a rolling process and improves the product quality. After using the method, the gate footstep shear improves the width measurement precision of a steel plate.
