摘要
基于煤矿高浓度胶结充填专用液压支架设计的可靠性,研制了ZCL7200/16/26型高浓度胶结充填专用液压支架,并采用Solidworks三维建模平台建立充填液压支架模型,运用有限元分析支架在模拟加载、偏载工况下关键构件应力、变形分布状态,考察支架整体结构稳定性和结构强度,研究表明:专用充填支架强度有限元分析结果均在设计允许范围内,支架整体性、稳定性满足充填工作面使用要求;支架现场应用整体性好、强度高、抗扭性好、可靠度高、移架速度快,充填体固结后尾梁能够顺利撤出,对回采高度及充填体高度变化适应性好,顶梁、立柱在试用过程中应力、变形等参数值均满足液压支架通用技术要求,取得了良好的技术经济效果。
To analyze the reliability of the special hydraulic support for coal mining high concentration cementation stowing, based on the brief introduction about backfilling technology and technique of coal mining high concentration cementation stowing, ZCL7200/16/26 hydraulic support is developed. Solidworks 3D model is adopted to build parametric model of coal mining hydraulic support. Finite element analysis is applied to analyze stress and deformation distribution of key component under simulation loading and unbalance loading working, to investigate the support overall structural stability and strength. Research indicates： the finite element analysis results are within the required range indicating favorable support integrity and stability; the support shows good integrity, high strength, high reliability and fast advancing supporting speed in field practice, and beam can be pulled out smoothly after back filling consolidation; besides it adapts the height of support and filling body well; stress and deformation monitoring parameters of top beam and upright in trial meet the general technical requirements of hydraulic support. Good technical and economic effects have been achieved.
