Mining Products Safety Approval and Certification Center

针对目前矿用防爆锂电池无轨胶轮车暂无针对性的国家、行业标准,装备设计、检测与认证依据缺乏的现状,在充分考虑现有相关标准规定、煤矿井下车辆运行的恶劣环境以及复杂工况的基础上,以锂电池、底盘、车身等防爆锂电池无轨胶轮车关键结构与部件为主要对象,研究提出锂电池优选与安全使用、底盘与车身结构合理设计、自动保护监控系统优化配置等方面的安全要求,该要求在6家企业的20多台锂电池无轨胶轮车设计、检测中进行了应用验证,结果表明,锂电池无轨胶轮车相比防爆柴油机无轨胶轮车,运行成本降低3/4以上,出勤率提高近30%。

According to the present situations of temporary non related national and industrial standards and non equipment design, test and certification basis for t he present mine flame-proof trackless rubber tyre vehicle powered with a lithium battery, in a full consideration of the available related standards and regulations as wel . I as the severe operation environment and the complicated performances of the vehicle in an underground coal mine, with the lithium battery, chassis, vehicle body and the key structure and components of the mine flame-proof trackless rubber tyre vehicle powered with lithium battery as the main object, the study provided the optimize d selection and safety application of the lithium battery, the rational design of the chassis and vehicle body structure, the optimal allocation of the automatic protection a nd monitoring system and other aspect safety requirements. The requirements would have the application certification on the design and test of over 20 set trackless ru bber tyre vehicles powered with the lithium battery from 6 enterprises. The results showed that in comparison with the flame proof diesel engine trackless rubber tyre ve hicle, the operation cost of the flame-proof lithium battery trackless rubber tyre vehicle could be reduced over 3/4 and the attendance rate of the flame-proof lithium batt ery trackless rubber tyre vehicle could be improved by near 30%.
