摘要
在综采工作面的机头机尾处会布置过渡液压支架,掩护式过渡架常采用比中间架顶梁加长的结构形式,而底板比压是液压支架的重要技术特征参数之一,因此有必要分析顶梁加长对于底板比压的影响,从而研究过渡架的受力及结构的设计优化。
Layout transition hydraulic support in fully mechanized coal face at the nose and tail,the shield transition hydraulic structure often used than the middle frame roof beams lengthened bottom pressure hydraulic support one of the parameters of the technical features,it is necessary to analysis the top beam lengthened for bottom pressure,force to study the transition frame and structure design optimization.
