【摘要】 介绍了 JSBZ132型臂式掘进机的新型工作机构,通过对工作机构各杆件的受力分析,导出在肱臂液压缸、尺臂液压缸和水平回转液压缸作用下的截割头牵引力.根据工作机构各构件的相互协调性原则,确定了各个液压缸和截割力之间的匹配关系式,为确定其工作压力和选型提供依据.更多还原

【Abstract】 This paper introduces the new working mechanism of JSBZ132 road headers.By mechanics analysis to all rods of the working mechanism,the cutterhead’s driving force created respectively by the humerus hy- draulic cylinder,ulna hydraulic cylinder and turning hydraulic cylinder are deduced.In order to improve the in- ternal harmony of the working mechanism,the matching relativities of cylinders and cutting force of the cut- terhead are established,which can help to select hydraulic cylinder type and its working pressure.更多还原
