铁路道床边坡收碴整形是工务部门的主要作业项目之一,过去多以手工为主,劳动强度大、质量差、效率低。目前一些工务段使用链耙式和皮带滚筒式收碴机,前者结构复杂,对不规则边坡形状作业适应性差;后者属半机械化作业方式,两人配合操作,劳动强度大,收碴整形质量差、作业效率低,两者至今仍未能在现场普遍使用。国外则以大型整形车为主, Ballast ballast rail ballast is a ballast plastic works one of the main operations, in the past mostly hand-based, labor-intensive, poor quality, low efficiency. At present, some work sections use chain rake and belt roller type ballast, the former has complicated structure and poor adaptability to the irregular slope shape workings. The latter is a semi-mechanized operation mode, and the two work together with great labor intensity and plastic ballasting Poor quality and low work efficiency, so far the two have not been widely used in the field. Foreign large plastic vehicles are based,
