摘要
为了有效地提高煤矿的生产效率,减少工人的劳动强度,免去设备列车拉移过程的轨道安装和拆卸工序,确保井下辅助运输安全,实施综采工作面的自动化、高效开采,设备列车安全高效运行,文章使用自顶向下、逐步求精的程序设计方法,结合现有的大型设备提升机构,采用新的结构整体布置形式,设计了一种设备与轨道在大坡度巷道中的大步距交替自动前移,且能自主调偏的设备列车自移机构,以及一种能够随综采工作面的前移而前进的设备列车起重机构;并且对设备列车的平板车架与起重机构的支撑立柱进行拓扑优化设计,优化后平板车架与支撑立柱的质量分别降低了11.17%和12.84%,达到了机构轻量化设计要求。
In order to effectively improve the production efficiency of coal mine,reduce the labor intensity of workers,eliminate the track installation and disassembly process of equipment train pulling process,ensure the safety of underground auxiliary transportation,implement the automation of fully mechanized mining face,efficient mining,safe and efficient operation of equipment train.In this paper,a top-down,step by step refinement programming method is used in combination with the existing large equipment lifting mechanism,and a new overall structure layout is adopted to design an equipment train self-moving mechanism which can automatically move forward at alternating strides between equipment and track in a large slope roadway,and an equipment train lifting mechanism which can move forward with the advance of fully-mechanized mining face.The topological optimization design of the platform frame and the support column of the lifting mechanism of the equipment train is carried out.After optimization,the mass of the platform frame and the support column are reduced by 11.17%and 12.84%respectively,which meets the lightweight design requirements of the mechanism.
