Furthermore, through the cooperation of the detection ruler and the pantograph head, the difference in the length of the two pantograph heads can cover the width requirements of different pantographs. The short pantograph head is suitable for special scenarios or narrow rail lines. The 50mm scale mark on the PTFE grinding plate facilitates accurate measurement of the contact wire pull-out value, ensuring that the lateral alignment error between the pantograph and the contact wire is controlled within the millimeter level. Moreover, the segmented dynamic envelope contours of the straight section and the curved section can simulate the pantograph lifting range under different line conditions, avoiding pantograph-contact wire interference caused by lateral offset in the curved section.
