摘要
ZZ13000/28/60型液压支架应用于同煤集团坚硬顶板条件下,针对支架的受力状况,建立了支架的三维实体模型,分析了在偏载、扭转工况下支架的受力情况。结果表明,ZZ13000/28/60型液压支架适合同煤集团坚硬顶板的要求。
ZZ13000 / 28 / 60 type hydraulic support used in hard roof conditions of Datong Coal Group Company. According to the stress of the stent, established the bracket of the three-dimensional entity model and analyzes the force of hydraulic support, un- der torsion and offset load conditions. The results show that, hydraulic support meet the requirement of hard roof in Datong Coal Group Company.
