针对目前采煤机调高系统试验研究中滚筒加载方式存在的问题,设计了采煤机滚筒调高模拟加载实验台,该实验台可编程,能动态连续模拟滚筒各种煤岩介质截割工况,并实现截割介质机械性质的随机变化。试验结果表明,该实验台性能可靠,模拟载荷变化规律与实际截割载荷情况相似,满足采煤机滚筒调高系统的加载要求。 In view of the problems existing in the drum loading method in the experimental research of shearer raising system, a simulation loading experiment bench for the height adjustment of the shearer drum is designed. The experimental table can be programmed to dynamically and continuously simulate the various coal media cutters Conditions, and to achieve a random change in the mechanical properties of cutting media. The experimental results show that the performance of the experimental bench is reliable and the variation law of simulated load is similar to the actual cutting load, which meets the loading requirements of the drum heightening system of shearer.
