减震防磨损溜槽在山东京杭水铁联运中的应用

溜槽作为煤炭运输中连接运输设备和储煤设施的重要部件，其设计的合理性直接影响到整个生产系统。尤其落差大的溜槽在使用过程中，不仅噪声大，磨损快，而且还会对下一级胶带冲击很大。实际生产中，溜槽维护成本高，严重影响煤炭运输正常作业。结合山东京杭水铁联运项目中溜槽运量大、落差高的特点，阐述了常用的防冲击、减震防磨损的方法以及在实际使用中的优缺点。并结合设计经验，提出了新的应用设计，通过计算机头落煤曲线，得出机头溜槽物料大概落煤点，设计堆煤网格，形成集料槽；在溜槽底板设置阻尼层，并用螺栓固定，起到缓冲减震降噪的作用。同时也起到了保护下一级胶带和落煤点缓冲托辊的作用。
