对分体式煤矿坑道钻机履带化改进进行了研究,提出了采用单泵阀控流量分配系统解决方案,给出了阀控流量分配系统的基本原理,利用AMESim软件分析及现场实验研究分析阀控流量分配系统对煤矿井下坑道钻机行走负载适应性影响,并通过与其他流量分配系统对比,得出阀控流量分配系统可实现煤矿井下坑道钻机行走回路负载独立流量分配的结论。
The improvement of crawler of drilling rig in split coal mine was studied. The solution of flow distribution system with single-pump valve was put forward. The basic principle of valve-controlled flow distribution system was given. Using AMESim software analysis and field experiment to analyze valve flow The effect of the distribution system on the adaptability of the running load of tunnel boring machine in coal mine is compared with that of the other flow distribution systems. The conclusion is that the valve controlled flow distribution system can realize the independent flow distribution of the load in the walking tunnel of coal mine tunnel.
