高度可自动调节的采煤机支撑装置研究

Research on Support Device with Automatic Height Adjustment of Shearer

针对采煤机在俯采和仰采时机身倾斜导致行走系统受力状况差的难题和采煤机配套不同工作面需要频繁调整滑靴高度从而造成成本增加的问题,研究一种高度可调节的采煤机支撑装置,来适当调整采煤机的工作状态和配套关系。应用效果表明:高度可调节的支撑装置在采煤机中的应用,提高了采煤机的机身稳定性,同时降低了采煤机的使用成本,可满足复杂工作面对采煤机适应性的要求。

Aiming at the difficult problem that the mining machine inclines at the time of overhand mining and overhand mining,which leads to the poor stress state of the walking system,and the slipper height needs to be adjusted frequently for different working faces of coal mining machine,which causes the cost increase,a highly adjustable support device for coal mining machine was studied,to adjust the working state properly and supporting relationship of the shearer.Application results show that the support device which can automatically adjust the height in the shearer improves the stability of the shearer fuselage,reduces the cost of the shearer,and can meet the requirements of the shearer adaptability in complex work.
