采煤机螺旋滚筒修复工艺的探讨

Discussion on Repairing Technology of Shearer Spiral Drum

螺旋滚筒式采煤机是煤炭开采中使用最为广泛的采煤设备,其中螺旋滚筒是滚筒式采煤机工作的核心部件,它要完成装煤、落煤、降尘和冷却截齿及扑灭切削火花等工作。由于螺旋滚筒结构与被截割煤岩体直接接触,属采煤机中最易磨损和损坏的部件。为提高采煤机螺旋滚筒的可靠性,对其修复工艺进行分析研究,同时制订了螺旋滚筒的大修工艺。经实际维修测试表明,该修复工艺可满足现场生产的要求。

Spiral drum shearer is the most widely used mining equipment in coal mining, which is the core component of spiral drum shearer, it can finish the loading of coal dust and the cooling effect of cutting pick and extinguish the spark. Because of the direct contact with the cutting coal and rock mass, the spiral drum structure can be most easily worn and damaged part of the shearer. In order to improve the reliability of shearer spiral drum, the repair process has analyzed and studied. The actual maintenance shows that the repairing technology has meet the requirements of field production.
