按照苏联煤和油母页岩矿技术操作规程的要求,立井单绳提升设备的过卷高度不小于2.5m.西乌克兰煤矿生产联合企业十月革命50周年矿由于箕斗加长,过卷高度减小到2.1m,同时,这个矿已开采了30多年,井架锈蚀严重,部件接头已很脆弱,如不加改造,是很不安全的。 最初改造井架工程的设计是采用斜撑和吊车进行拆装井架,吊车悬臂长度不应小于6.5m。乌克兰煤炭部顿涅茨设计公司按这些条件完成了预算设计。设计规定:从下部天轮平台起沿井架高度6m距离内,安装厚10mm的护壁钢板,用角钢加强
According to the Soviet Union coal and oil shale mine technical requirements, vertical shaft single rope hoisting equipment over the roll height of not less than 2.5m West Ukraine Coal Mine production joint ventures 50th anniversary of the October Revolution due to skip skip lengthened to reduce the height to 2.1 At the same time, the mine has been mined for more than 30 years and the derrick has been seriously corroded. The joint of the components has been very fragile. It is unsafe if not modified. The first transformation of derrick engineering design is the use of bracing and crane for derrick, crane cantilever length of not less than 6.5m. Donetsk, the Ukrainian coal ministry, completed the budget design on these terms. Design requirements: from the lower day wheel platform along the derrick height 6m distance, the installation of 10mm thick protective wall steel, with angle steel to strengthen
