摘要
MG400/930-WD采煤机外牵引行走轮上的端盖和挡板经常出现掉落的现象,从而引起不同类型的故障,严重地制约着综采工作面正常生产。通过对其外牵引进行了分析、研究,并对多个部位进行技改,大大降低了采煤机外牵引的故障率,提高了经济效益。
Because design is not ideal, it often occurs the traction walking wheel end cover and a baffle falling phenomenon in MG400/930-WD shearer, which resulted in different types of faults, and seriously restrict the normal production of fully mechanized working face. The traction was analyzed carefully and studied, and the technical transformation of many parts was carried out. Through these improvements, the accident rate is greatly reduced, and the production cost is reduced, and the economic benefit is improved.
