摘　　要：针对阳煤集团老矿井支架设备更新换代的需求,采用立柱新型外压固定结构,设计ZFY7800/17/32D型两柱放顶煤液压支架,优化抬底机构布置形式,实现支架结构紧凑型设计,增强支架的支护性能,降低支架的质量。According to the update requirements of support equipment in old mines of Yangquan Coal Group, the new fixed structure of column under external pressure is adopted to design ZFY7800/17/32D type two-leg top coal caving hydraulic power support. Some optimizations for the bottom lifting mechanism realize the compact structure and enhance the support performance and reduce the weight.
