摘　　要：以某种型号的锚杆钻车上的钻臂滑移机构为研究对象,对其在巷道进行锚杆支护作业的工况进行阐述。利用悬臂梁模型构建了伸缩架体的力学模型,推导出伸缩架体集中应力与伸缩架体滑移的距离成正相关。模拟最危险的工况下,通过三维仿真软件对伸缩架体和固定架体展开应力分析,证明了该钻臂设计的强度和刚度满足要求,在对滑移机构的分析中发现其薄弱环节为伸缩架体,通过在伸缩架体内增加贴板的改进措施,将最大集中应力由144.8 MPa降低至75.8 MPa。The drilling arm sliding mechanism of a certain type of bolt drilling rig was taken as the research object,and the working conditions of bolt support in roadway were explained.The mechanical model of telescopic frame was constructed by using cantilever beam model,and it is deduced that the concentrated stress of telescopic frame is positively related to the sliding distance of telescopic frame.Simulating the most dangerous working conditions,the stress analysis of the telescopic frame and the fixed frame was carried out by three-dimensional simulation software,which proves that the strength and stiffness of the drilling arm design meet the requirements.In the analysis of the sliding mechanism,it is found that the weak link is the telescopic frame,and the maximum concentrated stress is reduced from 144.8 MPa to 75.8 MPa through the improvement measures of adding stickers in the telescopic frame.
