我矿矿体倾斜角在3°～4°,掘进、采矿工作面的装矿设备均采用H600电力装岩机。在装矿作业中,由于铲斗频繁撞击缓冲弹簧,不但弹簧极易损坏,而卡簧又经常脱出,并易断裂,从而导致卡簧频繁装修、更换。不但卡簧的耗损量大,维修费高,而且因停产检修而影响生产。 我们针对缓冲弹簧存在的问题,将卡簧取消,把压板焊接在弹簧套内,拆除底板7 I ore body tilt angle of 3 ° ~ 4 °, mining, mining face loading equipment are used H600 electric rock loader. In mining operation, due to the frequent impact of the bucket buffer spring, not only the spring is extremely vulnerable, but often spring out prolapse, and easy to break, resulting in frequent replacement card spring replacement. Not only retainer card wear and tear, maintenance costs, but also because of production and maintenance shutdown affect production. We address the buffer spring problems, the retainer canceled, the plate welded in the spring sleeve, remove the bottom plate 7
