采煤机行走箱担负着整个采煤机在刮板输送机上的行走任务,并和平滑靴一起支撑着整个采煤机,所以它的可靠性直接影响着采煤机在井下的工作情况,然而从现实来看,由于井下恶劣而复杂的环境,使得行走箱的零部件,特别是齿轨轮和导向滑靴,容易失效损坏,因此,为了确保方便快捷的更换,对行走箱结构作了局部改进,改进后效果显著。 The coal shearer walking case carries the entire shearer’s walking task on the scraper conveyor and supports the shearer along with the smoothing shoe, so its reliability directly affects the work of the shearer under the well. However, From a practical point of view, because of the harsh and complicated underground environment, the components of the traveling box, especially the gear wheels and the guide shoes, are easily damaged and damaged. Therefore, in order to ensure convenient and quick replacement, the structure of the traveling box is partially made Improve, improve the effect is remarkable.
