摘要
为了降低SL3装船机悬臂煤炭作业仰角,合理选取了优化溜筒长度的方法,通过对抛料铲煤流过程轨迹进行模拟并修正,确定了实际煤流轨迹的近似抛物线模拟函数,通过该函数得到了同抛料点处不同溜筒长度的抛料距离,结合实际装船要求合理选取溜筒筒体长度优化截短范围为1.5~2m,同时给出了装船作业煤尘抑制方案。方案实施后,悬臂作业仰角降低了3°~5°,满足了悬臂低仰角作业要求,各船型各轮次的流程作业效率平均提升了95t/h,经济效益显著。
In order to reduce working boom lifting angle of SL3,the reasonable method for chute length optimization is selected,through simulating and amending the throwing coal track of chute bucket,actual throwing coal track function is confirmed,in the same position and different chute length,different throwing coal distance is obtained.Considering the working requirements of SL3,the shortening length of SL3 chute is 1.5~2 m,meanwhile controlling method of SL3 working coal dust is introduced.After the solution is carried out,working lifting angle of SL3 boom is reduced up to 3°~5°,SL3 works well,working process flow-rate of SL3 is added up to 95 t/h,and the economic benefit is improved.
