对首台国产化采煤机行走箱进行了工业性试验研究。试验中该行走箱取得了最大2.85万t/d产量、最大7.6 km/d行走距离的成绩;该行走箱齿轨轮组、导向滑靴等易损件取得了持续过煤430万t、持续行走1 065 km的成绩。达到了预期的研发目标和设计要求。为后续采煤机行走箱的改进提高以及采煤机整机的国产化研究工作积累了丰富的经验。
Industrial test and research on the first domestic coal shearer walking box. In the experiment, the walking box achieved the maximum output of 28,500 t / d and the maximum distance of 7.6 km / d. The wearing parts such as the gear rack and the guide shoe of the traveling box made a continuous 4.3 million tons of coal, Walk 1 065 km results. Achieved the expected research and development goals and design requirements. It has accumulated rich experience for the improvement and improvement of follow-up shearer walking box and the localization research of shearer machine.
