煤矿井下救生舱舱门设计及结构优化
|
摘要
针对救生舱舱门在煤矿救生系统工作中的重要性以及存在的不完善之处,提出了一种新型圆形煤矿救生舱舱门结构,对其抗冲击结构及锁紧机构的组成与工作原理进行了详细阐述,利用有限元软件对其抗冲击结构进行强度分析,并基于结果对结构进行优化,优化验证结果表明,舱门的安全系数由优化前的1.6提高到了3.1,满足了救生舱的设计使用要求,对救生舱的应用有着重要的现实意义。
According to the particularity of the blast airtight door of coal mine refuge chamber in the coal mine safety work and its widespread shortcomings, a new structure of the coal mine refuge chamber′s door was proposed. The composition and working principle of the anti-impact structure and the locking mechanism was explained. The strength of the anti-impact structure was analysised by the finite element software. Based on the analysis results, the anti-impact structure was optimized. And the optimization results presented that the safety factor of the cabin door was improved to 3.1 from 1.6,satisfying the design requirements of the refuge chamber, which has the important practical significance for the application of the refuge chamber.
