矿用带式输送机可伸缩机尾力学特性仿真分析研究

Simulation Analysis of Mechanical Characteristics of Telescopic Tail of Mining Belt Conveyor

针对有关带式输送机在综掘面使用过程中存在的问题,在现有带式输送机的基础上,设计一款可伸缩机尾,并通过输送带张力逐点计算方法、静力学分析方法分析在各种工况下的输送带张力及架体受力情况。结果表明在上坡过程中,输送带张力过大,机尾重力分力所能提供的摩擦不足以支撑输送带张力,保证带式输送机的正常运行,需进一步对结构做改进设计。同时根据有限元分析方法对伸缩结构进行静力学分析,验证其结构满足强度要求。研究成果可作为研究基础为后续优化研究提供可靠支撑。

In view of the problems existing in the use of belt conveyor in fully mechanized mining face,based on the existing belt conveyor,a telescopic tail is designed,and the belt tension and frame stress under various working conditions are analyzed by point-to-point calculation method of belt tension and static analysis method.The results show that in the uphill process,the belt tension is too large,and the friction provided by tail gravity component is not enough to support the tension belt,to ensure the normal operation of belt conveyor,the structure needs to be further improved.At the same time,the static analysis of the telescopic structure is carried out according to the finite element analysis method to verify that the structure meets the strength requirements.The research results can be used as the research basis to provide reliable support for subsequent optimization research.
