我处在立井井筒施工中,为提高工作效率,加快施工速度,适应大段高砌壁的需要,设计了三层吊盘。 三层吊盘的结构系在原两层吊盘下面,用4根钢丝绳再悬吊一层盘(附图)。上、中两盘为刚性连接,连接立柱使用工字钢,层间距4m,中、下两盘为柔性连接,连接钢丝绳直径视下盘的荷载而定,层间距7～8m。吊盘使用两台JZM-40/1350型凿井绞车悬吊。
I was in shaft shaft construction, in order to improve work efficiency, speed up the construction speed, to meet the needs of a large section of high walls, designed a three-tier hanging plate. The structure of the three-tier hanging plate below the original two-story hanging plate, with four rope re-suspension layer of plate (with photos). The upper and the middle two plates are rigidly connected, the connecting columns are made of I-beam, the distance between layers is 4m, the middle and lower plates are flexible connections, the diameter of the connecting wire rope is determined by the load on the lower plate, and the distance between layers is 7-8m. Suspension using two JZM-40/1350 sinking winch hanging.
