摘　　要：刮板输送机应用于铝土矿综采工作面时,因铝土矿石主要成分为Al_(2)O_(3),硬度高,刮板输送机磨损严重,寿命低,无法满足使用要求。针对该问题,通过提升关键零部件材料性能、改进结构、提高易磨损部件的维护便捷性、降低刮板链速度等措施,以提高设备的耐磨性,并应用在瓦厂坪铝土矿1101工作面。通过对中部槽和刮板磨损情况实测分析,改进后的中部槽耐磨性提升明显,预计寿命可达到设计要求;刮板长度方向磨损较严重,但未发生刮板断裂、跳出链道等事故;中部槽可在下个工作面继续使用,刮板可采用堆焊方式修复后在下个工作面继续使用。When the scraper conveyor is applied to fully-mechanized work face of the bauxite mine,since the main component Al_(2)O_(3) of bauxite ore is of high hardness,the scraper conveyor is seriously worn with low lifespan,thus the service requirement fails to satisfy.In view of the problem,such measures were taken as improvement of the material properties of key components,structural optimization,enhancement of the maintenance convenience of easily worn parts,and reduction of the scraper chain speed,so as to improve the wear resistance of the scraper conveyor,which had been applied on work face 1101 in Wachangping bauxite mine.The measurements of middle groove and scraper showed the wear resistance of improved middle groove greatly enhanced,and the expected service life could meet the design requirement;the scraper wore seriously in length direction,but there was no accidents such as scraper breaking or jumping out of chain track;the middle groove could be used again on next work face,and the scraper could be used again on next work face after being repaired via surfacing weld.
