摘要
煤矿辅助运输单轨吊设备在井下巷道内垂直转弯处重载运行时,单轨吊承载轨道的悬挂连接处或者轨道的腹板位置会发生折弯甚至发生断裂状况。通过SolidWorks建立单轨吊设备、轨道以及悬挂的三维模型,以单轨吊所使用两个连续I140E轨道之间的夹角α和单轨吊重载垂直转弯时起吊梁最后一个承载车和下方第一个驱动部的连杆和轨道之间的夹角β为变量,以轨道在受到冲击时轨道的最大应力和最大应变量为约束,对单轨吊运输车驱动和轨道分析,并结合轨道失效位置,找到引起轨道失效的原因。选用石家庄煤矿机械有限责任公司的DC280/160Y防爆柴油机10驱单轨吊车,通过分析、计算、建模、仿真,提出辅助运输连续化作业优化方案,结合工程验证,证明了方案的可靠性,为煤矿辅助运输设备连续化作业的高效安全提供经验借鉴。
When the coal mine auxiliary transport monorail crane equipment runs at the vertical bend in the underground roadway,the suspension connection of the monorail bearing track or the web position of the track will bend and even break.The three-dimensional model of monorail equipment,track and suspension is established using SolidWorks.The angleαbetween the two continuous I140E tracks used by monorail and the angleβbetween the connecting rod and track of the last bearing car of the lifting beam and the first driving part below the monorail heavy load during vertical turning are taken as the variables.With the maximum stress and maximum strain of the track under impact as constraints,the driving and track of the monorail crane are analyzed,and the cause of track failure is found by combining the failure location of the track.The DC280/160Y explosion-proof diesel 10-drive monorail crane of Shijiazhuang Coal Mine Machinery Co.,Ltd.is selected.Through analysis,calculation,modeling and simulation,the optimization scheme of auxiliary transportation continuous operation is proposed.Combined with engineering verification,the reliability of the scheme is proved,which provides experience for the efficient and safe continuous operation of auxiliary transportation equipment in coal mine.
