摘　　要：支架搬运车是一种用于煤矿井下单元支架快速搬家的辅助作业装备,直接与支架接触的叉装机构作为搬运车上主要受力的关键结构,其强度、刚度影响搬运车的使用寿命。基于有限元分析理论,对叉装机构各个关键部件进行受力分析,建立有限元模型,得出了门架C槽、上下滑移机构、左右滑移机构、货叉等关键部件的应力场分布及危险位置,与实际应力破坏相符。结果表明,叉装机构的设计满足实际工况的强度使用要求。The support carrier is an auxiliary operation equipment for the rapid moving of the unit support of the underground in coal mine,and the fork mounting mechanism in direct contact with the support is the key structure of the main force on the carrier,which strength and rigidity influences the service life of the carrier.Based on the theory of finite element analysis,analyzed the stress on various key components of the forked mechanism,established finite element models,and obtained the stress field distribution and dangerous positions of key components such as the C-slot of the gantry,the upper and lower sliding mechanisms,the left and right sliding mechanisms,and the cargo fork,which are consistent with the actual stress failure.The results show that the design of the fork mounting mechanism meets the strength requirements of actual working conditions.
