The escalator comprises ladder columns and a plurality of steps, the two ends of each ladder column are connected with the railroad hopper car through an upper support and a lower support correspondingly, the multiple steps are arranged between the two ladder columns, a plurality of protrusions are arranged on the steps, through grooves are formed in the protrusions, and the through grooves are communicated with the ladder columns. The escalator for the railroad hopper car adopts a split structure and is convenient to disassemble and assemble, friction force and sliding materials are increased through the protrusions and the through grooves, use safety is improved, and corrosion of material accumulation to the escalator is reduced.
本发明公开了一种铁路漏斗车用扶梯及铁路漏斗车,包括:梯柱,梯柱的两端分别通过上支座和下支座与铁路漏斗车连接,多个阶梯,多个阶梯设置在两个梯柱之间,阶梯上设置有多个凸起,凸起上设置有通槽,该铁路漏斗车用扶梯采用分体式结构,方便拆卸安装,同时通过凸起和通槽增加摩擦力和滑落物料,提高使用安全性,减少物料堆积对扶梯的腐蚀。
