摘　　要：推移杆在液压支架移架中起着至关重要的作用。薄煤层液压支架由于结构特点,致使液压系统中进回液多通块布置出现位置紧张的情况,为了提高支架综合性能,故而创新设计了带供液功能的推移杆,提高了支架的整体性能。The pushing rod plays a vital role in the moving of hydraulic support.Due to the structural characteristics of the hydraulic support in thin coal seam,the layout position of the liquid inlet and return multi-pass blocks in the hydraulic system is tight.In order to improve the comprehensive performance of the support,the push rod with liquid supply function is innovatively designed to improve the overall performance of the support.
