加长顶梁对过渡液压支架技术参数的影响

在综采工作面中,过渡液压支架布置于刮板输送机的机头与机尾处,由于机头与机尾处的设备较多,通常要求过渡架滞后于中间架布置,而在工作阻力与调高范围等技术参数上又基本等同于中间架,所以过渡架大多采用中间架加长顶梁的形式,由于顶梁的加长,会使部分技术参数及受力状况产生一些变化,通过分析与计算将过渡架与中间架进行对比。

On Extension Top Beam of Parameters of Transition Hydraulic Support Technology

In the fully mechanized working face,decorate in transition hydraulic support of scraper coveyor head and tail place,because nose and the tail place many devices,usually require transition frame lags behind the middle frame decorate,while in the work resistance and raise scope technical parameter have basic equivalent to middle rack,so the transition frame is used mostly intermediate frame lengthen top beam type,due to the top beam lengthen,will make some technical parameters and stress conditions produce some changes,the following analysis and computation will transition wearing and middle rack were compared.
