The invention discloses a furnace shell hoisting device for blast furnace overhaul and a mounting and using method thereof, and relates to the technical field of metallurgical industry production. The bearing beam is arranged below the large platform of the furnace body frame, the track beam is arranged below the bearing beam, the electric hoist is arranged below the track beam, car stops are arranged at the head end and the tail end of the track beam, the bearing beam is connected with a large platform secondary beam and a large platform main beam, and a first supporting frame is arranged on the side, close to a blast furnace casting house, of the bearing beam. An angle brace is arranged between the first supporting frame and the large platform of the furnace body frame. The hoisting device has the beneficial effects that the hoisting device is simple in structure, the spandrel girders and the electric hoists are slightly modified to be suitable for replacement of blast furnace overhaul furnace shells with various furnace capacities, the two spandrel girders and the two track girders can be mounted in advance before the blast furnace overhaul shutdown, a large amount of blast furnace overhaul period is saved, a sliding platform does not need to be additionally arranged, and the cost is reduced. The two functions of translation and lifting of the furnace top can be considered, and the furnace shell can be hoisted to the installation position from a casting house at a time.
一种高炉大修用炉壳吊装装置及其安装使用方法,它涉及冶金工业生产技术领域。承重梁设置在炉体框架大平台的下方,承重梁的下方设有轨道梁,轨道梁的下方设有电动葫芦,且轨道梁的头尾两端均设置有车档,承重梁连接其大平台次梁与大平台主梁,承重梁在靠近高炉出铁场侧设置有第一支撑架,第一支撑架与炉体框架大平台之间设有隅撑。本发明有益效果为本:吊装装置,结构简单,其承重梁和电动葫芦略作修改可以适用于各种炉容的高炉大修炉壳更换,两根承重梁和两根轨道梁可以在高炉大修停炉前提前安装,节省了大量的高炉大修工期,且不需要另外设置滑移平台,可以兼顾炉顶的平移和提升两种功能,可以一次性将炉壳从出铁场吊装至安装位置。
