2075E回采工作面作为钱矿2011年重点工作面,小时产量1100t以上中,采面溜选用SGZ960/1050,下运皮带DSJ-120/3*200,但下运巷道由于地质条件限制配套SZZ960-400中双链刮板转载机结构庞大无法安装使用,决定安装一部SZB730/75型刮板转载机,但运量只有630t/h,无法满足运输要求,为此,决定对其进行提速改造,通过选型计算,将链速由1.34m/s提升到1.7m/s,更换新减速器,双电机拖动,将两侧护板加高,通过理论论证及现场使用情况,运量可达到1200t/h,满足安全生产需要,又对机头底部游动小车进行改造,使其可以骑在SDJ-120/140/3*200皮带上纵向移动,达到配套移动要求。
2075E mining face as money mine 2011 key face, the hour output of 1100t above, face selection of sliver with SGZ960 / 1050, the next belt DSJ-120/3 * 200, but under the road due to geological conditions supporting SZZ960-400 The structure of double-chain scraper reloader was too large to be installed and used. It was decided to install a SZB730 / 75 scraper reloader but the capacity was only 630t / h, which could not meet the transportation requirements. Therefore, it was decided to revamp and upgrade Selection calculation, the chain speed from 1.34m / s to 1.7m / s, replace the new reducer, dual motor drag, both sides of the guard raised, through theoretical proof and field use, the volume can reach 1200t / h, to meet the needs of production safety, but also to transform the mobile head at the bottom of the car so that it can ride on the SDJ-120/140/3 * 200 belt longitudinal movement, to meet the requirements of the move.
