带式输送机重段清扫器清扫效果分析与改进设计

为解决带式输送机重段清扫器清扫效果不稳定、清扫力调节不方便和使用寿命低等问题,首先对现有清扫器的工作原理进行了分析,确立了影响清扫效果的主要因素及清扫器的设计准则,从原理上对清扫器进行了改进,设计了新型的可调节式恒力矩重段清扫器,在清扫器工作特性分析的基础上对新型清扫器的工作性能进行了评价,并在大同煤矿集团公司井下进行了工业性试验,试验结果表明,该清扫器维护简单,运行状态稳定,清扫效果和可调节性好,使用寿命长,为清扫技术的不断完善奠定了基础。

Analyses of the load segment sweeper of the belt-conveyor sweeping effect and its revised design

In order to solve the problems of the load segment sweeper of the belt-conveyor sweeping effect instability,sweeping strength adjusting discommodiousness and low using life,the work theory of the existing sweeper was analyzed,the primary factor of influencing the sweeping effect and the design rule of sweepers were established.The sweeper was improved on the theory.The new adjustable constant torque load segment sweeper was designed.On the basis of the sweeper work trait analysis,the work capability of the new sweeper was evaluated,and the industrial experiment was put up in the well of Datong Coal Mine Group Corporation.The results show that the running state of the sweeper is steady,the sweeping effect and adjustability are good,the using life is long,and it is a basis of improving sweeping technique.
