【摘要】 架空乘人装置由于其结构简单、安全可靠、维修方便及投资小等特点,被广泛运用于矿井斜巷、平巷中,实现对井下工人的远距离运输。由于架空乘人装置存在飞车、断绳安全隐患,一旦发生故障将给煤矿带来巨大的经济损失和人员伤亡。而目前对此类事故的防护措施研究尚且不足,因此研究可靠的飞车、断绳保护技术具有重要的意义。通过对架空乘人装置保护装置的研究现状及问题探讨,钢丝绳的动力学模型以及架空乘人装置动态特性的研究,研制了抓捕制动效果明显的飞车、断绳保护装置。根据架空乘人装置的运行特点及飞车、断绳保护装置的设计原则,完成了飞车、断绳保护装置结构设计和液压系统总体方案及元件的选型计算；构建了飞车、断绳保护装置的虚拟样机,并在ANSYS有限元分析软件对主要受力部件进行强度和刚度校核的基础上,完成了对保护装置的优化设计；提出了监控系统的总体方案,设计了以S7-200PLC为控制核心的控制系统和MCGS组态软件开发的上位机监控界面；根据飞车、断绳保护装置的布置原则,对保护装置的最小数量及允许安装的最大距离进行了详细计算和分析,结合牵引钢丝绳张紧力分布的实际情况,确定了保护装置的安装布置方案。分析结果和实践表明,飞车、断绳保护装置结构设计合理,动作灵活,系统稳定可靠,能够在飞车、断绳故障时快速可靠地抓捕和并使架空乘人装置停止运行。更多还原

【Abstract】 Aerial passenger device is widely used in mine inclined and level lane to realize the long-distance transportation of the underground workers for its characteristics of simple structure, safe and reliable, convenient maintenance, low investment and so on. Due to aerial passenger device exists hidden danger of runaway fast and rope broken, it will bring economic losses and casualties for mine in the event of fault. And current research of protective measures of such accidents is still insufficient, so the research of runaway fast and broken rope protection technology has very important significance. Based on the research state and problems discussing of aerial passenger device protectors, the wire rope dynamic model and aerial passenger device dynamic characteristics research, a runaway fast and broken rope protector of obvious braking effect is developed.According to operation characteristics of the aerial passenger device and design principle of runaway fast and broken rope protector, the structure design, hydraulic system scheme and the selection calculation are completed. Virtual prototype of the runaway fast and broken rope protector is built. And optimization design of the protector is accomplished based on strength and rigidness checking of the main mechanical parts by the ANSYS finite element analysis software. The overall scheme of monitoring system is proposed, the control system in core of S7-200PLC and the PC monitoring interface developed by configuration software MCGS are designed. In accordance with the layout principle of runaway fast and broken rope protector, the minimum quantity of protectors and the maximum installation distance allowed have carried on detailed calculation and analysis. Combining with actual tension distribution situation of drawing wire rope, the installation layout scheme of protectors is determined.The analysis results and practices show that the structure design of runaway fast and broken rope protector is reasonable, movement is flexible and system is stable and reliable. It can catch the broken rope quickly and stop the running aerial passenger device.更多还原
