煤矿装车平煤过程中,若平煤器的平煤板抬起发生故障,就会造成平煤器损坏、火车牵引绞车烧毁,甚至更严重后果。通过对平煤板的受力分析,找出其薄弱环节,从切向破坏力入手,设计平煤器故障碰撞安全保护结构,并提供其选材依据。 In the process of loading coal in a coal mine, if the flat coal plate of a flat coal mine is lifted and fails, it will cause damage to the flat coal mine, burn the traction winch, and even more serious consequences. Through the analysis of the force of flat coal slab, the weak links are found out. Starting from the tangential destructive force, the structure of the fault protection and safety protection of the coal slab is designed, and the material selection basis is provided.
