我矿使用 IKJ2×2.5×1.2D 矿井卷扬机,钢丝绳直径 =31毫米,每个筒壳上需装木衬56块。每块木衬尺寸为;1200×140×85。过去更换木衬时,先将木衬装到筒壳上,再在木衬上画螺旋线与刻制螺旋槽,工作繁琐费力,每更换木衬一次,需要停产三天。1978年我们采用木衬预制刻槽,只需半天时间便顺利地装好全部木衬。 I mine using IKJ2 × 2.5 × 1.2D mine hoist, wire rope diameter = 31 mm, each cylinder shell required to install 56 wood lining. Each piece of wood lining size; 1200 × 140 × 85. In the past to replace the wood lining, the first wood lining mounted to the cartridge shell, and then draw on the wood lining on the helical spiral and engraved spiral groove, tedious work, each replacement wood lined, need to stop production for three days. In 1978 we prefabricated wood lined grooves, just half a day will be well installed all the wood lining.
