Description
Technical field
The invention belongs in the building or the liftable bearing set that cooperates with building, relate in particular to the service platform for construction operation in the State of Blast Furnace.
Background technology
More than the Modern Large Blast Furnaces diameter 10m, up to tens of rice, need to install hundreds of piece cooling wall in the stove.From bottom to top successively construction of cooling wall is installed, and amount of high-altitude operation and construction intensity are all very large, set up scaffold and cooling wall is installed without possibility in burner hearth.Adopt the annular hanging scaffold that is provided with service platform during current installation blast furnace cooling stave, hanging scaffold is hung on the haulage cable, is elevated to suitable height by winch, successively installs.The annular hanging scaffold of current use is connected and composed by girder, collar tie beam, spoke, landing slab and center railing, and landing slab is fixed on the spoke, and spoke is fixed on the collar tie beam, and collar tie beam is fixed on the girder, and girder is hung on the haulage cable.The hanging scaffold diameter is convenient to hanging scaffold vertical lift and smoothly turnover in blast furnace less than the minimum diameter of blast furnace inwall.But when being installed to the larger position of cupola well or the such diameter of bosh band, it is large that hanging scaffold and blast furnace inwall spacing become, and must extend and bed board could satisfy the construction demand hanging scaffold.Adopt at present device to be: to insert steel pipe or shaped steel in the tubular spoke of hanging scaffold (pipe or square tube), when hanging scaffold rises to the position of blast furnace different inner diameters, the length that can regulate spoke by steel pipe or shaped steel in the flexible spoke, and then colligation or remove interim bed board on spoke, regulate the needs that the hanging scaffold diameter satisfies construction operation thereby reach.Its defective is: because the installation diameter of each layer cooling wall is not quite similar, when each layer cooling wall is installed, all will again extends or dismantle hanging scaffold, repeated disassembled and assembled hanging scaffold work capacity be large, is seriously restricting the duration of cooling wall installation, affects ironmaking production; The dismounting of hanging scaffold needs a large amount of artificial, and the consumption of material is also larger, and construction cost is high; Carry out disassemble and assemble work at the hanging scaffold edge and belong to aloft work, exist great potential safety hazard.
Summary of the invention
The defective that exists in order to overcome prior art the purpose of this invention is to provide a kind of hanging scaffold of installing and build by laying bricks or stones operation for cooling wall in the State of Blast Furnace, avoids delaying because of demolition, installation hanging scaffold service platform repeatedly, increase work efficiency, reduce labor intensity, the reduction of erection time, blast furnace puts into production in advance; Cutting down the consumption of raw materials eliminates safe hidden trouble.
Be used for the interior cooling wall of State of Blast Furnace and install and build by laying bricks or stones the hanging scaffold of operation, connect and compose circular disk body by girder, collar tie beam, spoke, landing slab and center railing, landing slab is fixed on the spoke, spoke is fixed on the collar tie beam, collar tie beam is fixed on the girder, girder is hung on the winding plant that blast furnace establishes by haulage cable, is characterized in arranging on the described disk body supporting track and support with the body concentric annular arrangement of dish; Rotating mechanism is loaded on the supporting track, and rotating mechanism rotates along supporting track, turns to construction location and is fixed by fixed mechanism; Travel mechanism establishes service platform in the front portion, travel mechanism's rear portion removable mounting is on rotating mechanism, travel mechanism moves as radial expansion along rotating mechanism, drive service platform and be toward or away from original position, arrive desired location, travel mechanism and rotating mechanism locking are by rotating mechanism and support supporting, before service platform just firmly is fixed on position to be installed.Improve the strength and stability of service platform, reduced or avoided the generation of safety misadventure.
The present invention further improves, and described rotating mechanism presses rail to consist of the rectangular box framework by turret, turret; Establish the lattice plate between on the turret, prop up the rear end of movable stand, both improved the intensity of turret, increase again the stability of movable stand; Turret is divided into rotor wheel, places on the supporting track, and turret rotates along supporting track, and turret is also established sliding roller and pin-and-hole; Described rotor wheel is the universal caster wheel with service brake, and pin is stepped on just and can be braked or unclamp, and is easy to operate.
The present invention further improves, and establishes 3-5 rotating mechanism on the described disk body, and each rotating mechanism rotates 80 °-120 ° along supporting track, can cover one week of blast furnace inwall, satisfies the needs that one deck cooling wall is installed.
The present invention advances a bit to improve, and described travel mechanism consists of rectangular frame by movable stand, service platform, oblique pull steel rope and lap plate, and the travel mechanism rear portion places on the sliding roller that arranges in the turret; The oblique pull steel rope is connected the oblique pull movable stand with the calabash that pulls on being located at the last furnace shell bolt; Movable stand moves as radial expansion along the sliding roller of turret, and behind the arrival construction location, lap plate rides on the mounted lower floor cooling wall, gains in strength and stability; Pin-and-hole also is set on the movable stand, corresponding with the pin-and-hole that rotation is set up, pin movable stand and turret by bearing pin or pin.
Last improvement of the present invention, operated platform is made of walkway board, arc-plane plate and gusset bar, and walkway board and arc-plane plate are fixed on the movable stand rib plate; Movable rail is established in walkway board and arc-plane plate both sides, is plugged in the mobile assembly opening that sets up, and guarantees construction safety, the conveniently detachable and increase and decrease of guardrail; The wide 550-750mm of described arc-plane plate, long 1500-1800mm can be for many people simultaneously at the cambered plate construction operation.
During work, by winding plant hanging scaffold of the present invention is promoted to operating altitude first, then forward turret to certain angle along the lower support track by rotor wheel, sliding moving frame forward or backward again, until the lap plate on the movable stand props up lower floor's cooling wall, service platform places the installation site, utilize stop mechanism that service platform is fixed, put on steel rope from the hold-down bolt hole of furnace shell upper strata cooling wall, establish the chain block traction at movable stand and live the oblique pull steel rope, to improve stability and the intensity of service platform.After service platform is adjusted, movable rail is inserted in the assembly opening of service platform and both sides, aisle establishing, the workmen enters service platform by walkway board, carries out installation exercise.
Compared with prior art, advantage is: novel, rational in infrastructure, simple, intensity is large, and stability is high, easily makes; The service platform area reduces, and cutting down the consumption of raw materials alleviates the weight of hanging scaffold; Hanging scaffold position and angular adjustment are convenient, fast, exempt the disassemble and assemble work of hanging scaffold bed board, save the labour, increase work efficiency reduction of erection time, favourable ironmaking production; The material of platen consumption and the machine-team expense of lifting device are paved in saving, are conducive to reduce executive cost; The camp site is clean and tidy, construction safety.
