煤矿井下主要运输线路轨道铺设量应满足什么?

日期:2019-12-05 16:32:00 | 人气:

煤矿轨道务必按规范铺设。主要运输煤巷轨道的铺设质量应合乎什么规定?

井下主要运输线路轨道

(1)脚手架扣件务必齐备、坚固并与轨型相符合。轨道连接头的空隙不可超过5mm,高矮和上下错差不可超过2mm。

(2)平行线段2条铁轨墙顶的高矮偏差,及其曲线图段外轨按设计方案加宽后与内轨墙顶的高矮偏差,都不可超过5mm。

(3)平行线段和扩宽后的曲线图段轨距上偏差为+5mm,下偏差为-2mm。

(4)在曲线图段内要设定轨距支撑杆。

(5)轨枕的规格型号及总数应符合标准规定,间隔偏差不能超过50mm。道碴的粒度分布及铺设薄厚应符合标准规定,轨枕下应捣实。对道床应常常清除,应无脏物、无浮煤、无存水。

同一路线务必采用同一型号规格铁轨。铁路道岔的钢轨型号,不可小于路线的钢轨型号。

煤矿轨道采用期内应提升维护保养,按时维修。
