摘　　要：针对国内铁路有砟轨道桥梁及隧道内线路清筛作业面宽度较窄,传统机械清筛存在困难问题,中国铁建高新装备股份有限公司研发出SQS-300K型桥隧专业清筛机,通过改用垂直式挖掘装置,实现对3100 mm(Ⅱ型枕)、3200 mm(Ⅲ型枕)宽度挖掘作业。对传统挖掘链增加破底齿,增强对板结道床破碎及挖掘能力,以实现对板结路段的快速清筛。为减少隧道施工过程中的有害气体,在作业编组平板车上增设4台轴流风机,减少了隧道内有毒气体残留。结合现场清筛作业过程出现的问题进行改进优化,证明SQS-300K型桥隧专用清筛机能满足桥梁和隧道内线路清筛要求,且可大幅提高铁路清筛质量和效率。Considering the cleaning operation surface’s narrow width of the bridge and tunnel’s railway and the difficulties of traditional mechanical machine cleaning,CRCC High-Tech Equipment Corporation Limited developed the SQS-300 K bridge and tunnel professional cleaning machine.The operation width of 3100 mm(Ⅱsleeper)and 3200 mm(Ⅲsleeper)can be excavated through using vertical excavation device.Through adding the bottom breaking teeth to the traditional excavation chain,the capacity of crushing and excavating the hardened track bed is enhanced,so as to achieve rapid cleaning on the hardened road section.In order to reduce harmful gas during tunnel construction,4 axial flow fans are added to the operation marshalling flat car,which reduces the residual toxic gas in the tunnel.Combined with the problems found in the on-site cleaning operation,it is proved that SQS-300 K professional cleaning machine can not only meet the screening requirements of lines in bridges and tunnels,but also greatly improve the quality and efficiency of railway cleaning.
