The invention discloses a novel railway tunnel ballast bed coal suction vehicle set and a corresponding operation method. The coal suction vehicle set comprises a side suction vehicle and a material vehicle, and a side suction vehicle frame (301) is installed on a third driving walking bogie (302) and a fourth driving walking bogie (311); the side suction vehicle frame (301) is n-shaped, at leastone set of the side suction working device (308) is arranged and located at the right-angle portion of an operation cab (307), the side suction working device (308) is connected with the side suctionvehicle frame (301) through a rotary supporting rotary table, the side suction working device (308) is fixedly connected with the rotary supporting rotary table, and a hydraulic motor drives a worm wheel to rotate via a worm, so that a mechanical arm swings out and in along the rotation axis. According to the railway tunnel sleeper outer ballast bed coal suction vehicle set, speed reduction designis conducted on the air ducts in the tops of a front draught fan chamber and a rear draught fan chamber of the side suction vehicle set, so that the ultrahigh air speed of a draught fan outlet is reduced to 2 m/s, and pulverized coal flying dust around the outlet is prevented.

一种新型铁路隧道道床吸煤车组及相应的作业方法，所述吸煤车组包括侧吸车和物料车，侧吸车车架(301)安装在第三驱动走行转向架(302)和第四驱动走行转向架(311)上；侧吸车车架(301)呈“几”字形，侧吸工作装置(308)设置至少一套，位于操作司机室(307)的直角部分，侧吸工作装置(308)通过回转支撑转台与侧吸车车架(301)相连，侧吸工作装置(308)与回转支撑转台之间固定链接，液压马达通过蜗杆驱动蜗轮回转，使机械臂沿回转轴线摆出及摆入。上述实施例所述铁路隧道轨枕外道床吸煤车组侧吸车前后风机室顶部的风道进行了减速设计，最终使风机出口的超高风速减低为2m/s，防止出口周围的煤粉扬尘。
