摘　　要：针对普通单体液压支柱存在的不足,提出了一种新型的高效单体液压支柱的结构原理,并对其关键结构件进行了设计,确定了各主要结构的尺寸,进行了强度校核,验算了支柱的稳定性。研究结果表明:新型高效单体液压支柱的升柱速度比原支柱快一倍以上,适用于破碎顶板,可广泛用于煤矿井下采煤工作面。Aiming at the defect of existing hydraulic prop, the structure principle of an efficient product has been put forward. Designed its key components and confirmed their main structured sizes, checked its strength and stability. The research results show that the rising speed of the new hydraulic prop is twice as large as that of the traditional one. The new hydraulic prop is suitable for broken roof and may be popularized.
