摘要
针对采煤机在综采作业时由于煤矿井下地质条件复杂、采煤机综采作业时受载荷冲击较大而导致其四轮行走机构频繁发生损坏的问题,以MG2型采煤机的行走机构为例,通过对MG2型采煤机销轨与采煤机截深关系分析,建立了仿真分析的数学模型,利用ADAMS仿真分析软件对采煤机行走机构与销轨在不同条件下的啮合特性进行了仿真分析,为优化采煤机行走机构、提升工作可靠性和使用寿命提供理论和技术支持。
In view of the frequent damage to the four-wheel walking mechanism of shearer due to the complicated underground geological conditions and the large impact of load in fully mechanized coal mining operation,this paper takes the walking mechanism of MG2 shearer as an example,and takes the driving mechanism of MG2 type shearer as an example.Based on the analysis of the relationship between the pin rail and the cutting depth of the MG2 shearer,the mathematical model of the simulation analysis is established.The meshing characteristics of the walking mechanism and the pin rail of the shearer under different conditions are simulated and analyzed by using the ADAMS simulation and analysis software.It provides theoretical and technical support for optimizing the running mechanism of shearer and improving working reliability and service life.
