Problems solved by technology
Its defect is: because the installation diameters of each layer of staves are not the same, when installing each layer of staves, it is necessary to re-extend or disassemble the suspension plate, and the workload of repeated disassembly and assembly of the suspension plate is large, which seriously restricts the installation of staves. The construction period affects ironmaking production; the disassembly and assembly of the hanging pan requires a lot of labor, the consumption of materials is also large, and the construction cost is high; the disassembly and assembly work on the edge of the hanging pan is a high-altitude operation, and there is a great potential safety hazard

Embodiment Construction
[0017] Depend on figure 1 , figure 2 It can be seen that the hanging pan used for stave installation and masonry in the blast furnace is composed of a main beam, a ring beam, spokes, a platform plate 2 and a central railing 3 to form a circular pan body 1 . The platform plate is fixed on the spokes, the spokes are fixed on the ring beam, the ring beam is fixed on the main beam, the main beam is hung on the hoisting device of the blast furnace 10 by the traction wire rope 11, and the disc body is provided with a ring-shaped ring concentric with the disc body. Support rail 5 and support 4. The rotating mechanism 6 is installed on the supporting track, and the rotating mechanism rotates along the supporting track, and is fixed by the fixing mechanism when rotating to the construction position. Moving mechanism 7 fronts establish operating platform 8, obliquely-stayed steel wire rope 7-3, and moving mechanism front end is also provided with lap plate 7-4, and moving mechanism r...

The invention discloses a hanging scaffold for mounting and building a furnace cooling wall in a blast furnace, and relates to an operation platform for furnace construction in the blast furnace. The hanging scaffold is a round plate body comprising a girder, a ring beam, spokes, a platform plates and a central handrail which are connected, and is characterized in that an annular support rail and a brace are arranged on the plate body; a rotation mechanism is mounted on the support rail; a moving mechanism provided with an operation platform is movably mounted on the rotation mechanism to drive the operation platform to approach or leave the original position; and the moving mechanism is locked with the rotation mechanism after arriving at a mounting position and is supported by the rotation mechanism and the brace. The hanging scaffold provided by the invention has the advantages of novel conception, reasonable and simple structure, high strength, high stability, and easiness for manufacture; the operation platform is reduced in area so as to reduce the material consumption and reduce the weight of the hanging scaffold; the hanging scaffold is convenient and quick to adjust position and angle, and obviates the assembly / disassembly of planks, thereby saving labor force, improving work efficiency, shortening construction period and facilitating iron-making production; the materials of the planks and the machine-team cost of a hoisting tool are saved so as to reduce the construction cost; and the construction site is clean and safe.
Description
technical field [0001] The invention belongs to a liftable support device in a building or matched with a building, in particular to an operating platform for construction operations in a blast furnace. Background technique [0002] Modern large-scale blast furnaces have a diameter of more than 10m and a height of tens of meters, and hundreds of staves need to be installed in the furnace. The installation of staves is carried out layer by layer from bottom to top, and the workload and construction intensity at heights are very large. It is impossible to install scaffolds in the furnace to install staves. Currently, when installing the cooling stave of blast furnace, an annular hanging pan with an operating platform is used. The hanging pan is hung on the traction wire rope, and is lifted to an appropriate height by a winch for layer-by-layer installation. The currently used ring suspension pan is composed of main beam, ring beam, spokes, platform plate and central railing. ...
