At the same time , the function of measuring coal in every coal storage bunker and measuring coal before its entering into every boiler greatly improves productivity of the whole loading and unloading coal system . . on the aspect of operation technics of the loading and unloading coal system , this article analyzes factors which affect operation technics of coal - whippers , stacking conveyers and pusher tractors . no standardization in daily operation , low safety , long operation time and out of line among different machines reduces the efficiency of the loading and unloading coal system 卸煤操作工藝方面,主要分析了卸船機(jī)、堆取料機(jī)和推扒機(jī)在日常作業(yè)過(guò)程中影響作業(yè)工藝的因素,在日常作業(yè)過(guò)程中主要存在問(wèn)題是無(wú)標(biāo)準(zhǔn)化作業(yè)要求,安全得不到保障,作業(yè)時(shí)間長(zhǎng),各作業(yè)機(jī)械之間配合差,從而影響整個(gè)卸煤系統(tǒng)的作業(yè)效率,本文通過(guò)對(duì)卸船機(jī)、堆取料機(jī)、推扒機(jī)作業(yè)流程的設(shè)計(jì),規(guī)定了單個(gè)機(jī)械的作業(yè)程序,以及相互之間作業(yè)時(shí)的配合方法,使卸船機(jī)作業(yè)和堆場(chǎng)作業(yè)更規(guī)范化,同時(shí),大大縮短卸船作業(yè)時(shí)間,提高了碼頭泊位利用率,減少機(jī)械作業(yè)時(shí)間,從而提高了整個(gè)輸煤系統(tǒng)的工作效率。
