摘　　要：针对采煤机在使用过程中调高油缸活塞杆弯曲变形,通过理论分析结合实践经验,排除了活塞杆过载的可能性,确定了活塞杆弯曲原因是煤矸堆积阻碍了油缸正常摆动,并提出了解决措施,为后续生产以及设计提供了借鉴和参考。Aiming at the bending deformation of the piston rod of height adjusting cylinder in the use of shearer,through theory analysis combining with the actual experience,the possibility of overload of the piston rod was excluded,and defined that the main cause of piston rod bending is coal and gangue accumulation which block the normal swing of the cylinder.The solution measures were put forward,which provides reference for subsequent production and design.
