中条山有色金属集团公司铜矿峪矿地下开采中,矿石装运采用美国进口的EST-3.5型电动铲运机,其优点是:运行效率高,故障率低,使用期限长,污染小。但易损件费用高,尤其是铲板。因此,该公司自行研制了EST-3.5型铲运机铲板,实现了铲板的国产化1 铲板的钢种设计及工艺制定1.1 工况分析铲板的工作过程分铲、装、运矿石3个分解动作。“铲”这个动作使铲板在一瞬间承受较大重量的冲击载荷,同时承受很大的挤压和弯曲载荷,还伴随 In the underground mining of Tongkuangyu Mine of Zhongtiaoshan Non-ferrous Metals Group Corporation, EST-3.5 electric scraper used by the United States imported by the United States has the advantages of high operation efficiency, low failure rate, long service life and small pollution. However, wearing parts are expensive, especially for shovels. Therefore, the company developed its own EST-3.5 scoop shovel to achieve the domestication of a shovel plate design and process of a shovel 1.1 Condition analysis Shovel plate work process, shovel, loading, ore transport 3 decomposition action. “Shovel ” This action makes the shovel in the moment to bear a greater weight of the impact load, while under great compression and bending loads, but also with
