摘　　要：分析了隔离布充填支架不同类型后部隔离装置的特点,设计了一种新型后部隔离装置,尾梁对充填区域具有持续支护能力,并通过变截面设计提高了支护能力,隔离装置通过连接杆间接铰接在顶梁上。针对隔离装置姿态调整复杂的问题,设置了上伸缩梁来增强隔离装置与顶板和尾梁之间的密封效果。The characteristics of different types of isolation cloth filling support rear isolation devices were analyzed,a new rear isolation device was designed.The tail beam provides continuous support to the filling area,and the support capacity is enhanced through a variable cross-section design.The isolation device was indirectly hinged to the top beam through connecting rod.To address the problem that adjusting the posture of the isolation device is complex,an upper telescopic beam was designed to enhance the sealing among the isolation device,the roof and the tail.
