底侧卸式矿车外动力卸载设施的研究与应用

Research and application of external powerunloading device for bottom unloading mining carts

大型有轨运输矿车设有专用卸载站,站内矿车沿卸载曲轨运行。针对矿车通过卸载站时电机车无法产生驱动力,导致矿车无法稳定通过卸载站问题,从矿车通过卸载站机械能变化情况出发,以塞尔维亚某铜矿卸载站为例,分析矿车卸载过程中速度变化情况,并通过设置外动力设施控制卸载运行速度,使大型有轨运输矿车卸载平稳可靠,对生产系统自动化起到了极大促进作用。

Large-scale tram transport mining carts are equipped with dedicated unloading stations,where the carts run along unloading curved tracks.Addressing the problem of electric locomotives unable to generate sufficient driving force for mining carts to pass through unloading stations stably,this study,taking the unloading stations of a copper mine in Serbia as an example,analyzes the speed variation of mining carts during unloading processes.By setting up external power device to control unloading speed,the unloading process of large-scale tram transport mining carts becomes smoother and more reliable,greatly promoting the automation of production system.
