针对进口采煤机配件及整机供应周期长、价格高,而用于采煤机行走的行走箱更换难度较大且配件更换频繁,导致生产成本增加,工作人员劳动强度增大等问题,在对进口采煤机行走箱进行研究分析的基础上进行了国产化研究应用,并分析探讨了研制过程中关键技术特点、质量保证措施及成功应用带来的经济效益。 For the imported shearer parts and machine long supply cycle, the price is high, and for the shearer walking walking box replacement more difficult and frequent replacement parts, resulting in increased production costs, increased staff labor intensity and other issues in the Based on the research and analysis of the imported shearer walking case, the localization and application of the coal shearer are studied. The key technical features, quality assurance measures and the economic benefits brought by the successful application are analyzed and discussed.
