一种新型地下混装炸药车自动送管系统的设计与应用

Design and application of a new automatic hose pushing system for Underground Mixed Loading Truck

输药管自动送管系统是地下混装炸药车必备的辅助系统之一,北京矿冶研究总院研制了一种新型自动送管器及其电液比例控制系统。通过在首钢矿业公司杏山铁矿的应用证明,该系统可实现上向扇形炮孔的机械化送管,可在退管装药过程中根据混装炸药输送速度进行比例调速控制,并且具备孔深探测等自动化功能,系统整体作业效率能够满足地下矿生产实际需求,可显著降低工人的劳动强度。

The automatic hose pushing system is one of the necessary auxiliary systems for Underground Mixed Loading Truck. Beijing General Research Institute of Mining ; Metallurgy has developed a new crawler hose pushing device and its electro-hydraulic proportional control system. The application of this system in Xingshan Underground Iron Mine has proved that it can be used to push mixed explosive loading hose into upward fan holes mechanically, form a proportional speed control with mixed explosive delivery system during the hose extracting and charging process, and had hole depth detection function. The efficiency of this system can satisfy the actual demand of underground mine production, thus it can reduce the labor intensity of workers dramatically.
