摘　　要：针对济钢原料厂 76型带式输送机运行状况差、故障率和备件消耗高、维护量大的状况 ,研究并实施了将 76型托辊架改为DTII型双向可变槽角自动调心托辊架等 ,有效解决了皮带跑偏撒料问题 ,减少了皮带运行阻力 ,降低了运行成本 ,实现了皮带自动纠偏功能。改造后 ,每千米皮带可获得年直接经济效益 13 7万元。Pointing to the status of bad operation condition, higher fault, higher consumption of spare part and big maintenance, etc, the raw material plant of Jigang has done transforming to 76 type belt conveyor which was replacing 76 type roller rack by DTⅡ type automatic centering roller racks with double way changeable slot-angle. As a result, it solves the problems of belt deviation and leakage of material, reduces the operation resistance of belt and operation cost, realizes automatic deviation correction of the belt. After transforming the direct economic benefit of 0.137 million yuan can be obtain from per-kilometer belt every year.
