The invention provides a steel derrick used for permanent lifting and also used as a kilometer vertical shaft full face heading machine. The steel derrick comprises a main leg, an auxiliary leg, a supporting platform, a lower head sheave platform for shaft sinking, an upper head sheave platform for shaft sinking and the like. The supporting platform is connected to the middles of the main legs and the auxiliary legs. The lower head sheave platform for shaft sinking is connected to the middle parts of the main leg and the auxiliary leg and positioned above the supporting platform; the upper head sheave platform for shaft sinking is connected to the middle parts of the main leg and the auxiliary leg and is positioned at the upper part of the lower head sheave platform for shaft sinking; the lower head sheave platform for permanent lifting is connected to the middle of the main leg and the top of the auxiliary leg and located on the upper portion of the upper head sheave platform for shaft sinking. The upper head sheave platform for permanent lifting is connected to the middle of the main leg and located on the upper portion of the lower head sheave platform for permanent lifting. The lifting beam platform is mounted at the top of the main leg; the two groups of derrick legs are respectively connected to two ends of the bottoms of the main leg and the auxiliary leg. The device can be used for permanent lifting, shaft sinking construction and shaft equipment installation at the same time, the shaft mouth occupation time is shortened, and the engineering investment is saved.
本发明提供了一种用于永久提升并兼作千米竖井全断面掘进机用的钢井架,包括主腿、副腿、支撑平台、凿井用下天轮平台、凿井用上天轮平台等;支撑平台连接在主腿、副腿的中部;凿井用下天轮平台连接在主腿、副腿中部,并位于支撑平台上部;凿井用上天轮平台连接在主腿、副腿中部,并位于凿井用下天轮平台上部;永久提升用下天轮平台连接在主腿中部、副腿顶部,并位于凿井用上天轮平台上部;永久提升用上天轮平台连接在主腿的中部,并位于永久提升用下天轮平台上部;起吊梁平台安装在主腿顶部;两组井架支脚分别连接于主腿、副腿底部两端。本发明可同时供永久提升、凿井施工及井筒装备安装时使用,减少竖井井口占用时间,节省工程投资。
