Description
Technical field
The present invention relates to the detachable operating platform of a kind of hood type, specifically, is a kind of detachable operating platform of hood type of blast furnace granulated slag steam discharge cylindrical shell and the application in blast furnace granulated slag steam discharge cylindrical shell renovates thereof.
Background technology
Baogang Stocks Trading Co.'s iron-smelter one, No. two blast furnace grain slag systems are INBA method grain slag treatment process, at north and south cast house, a set of independently grain slag treatment facility is respectively set, the a large amount of steam containing Korrosionsmedium produced in flushing cinder process, high-altitude is discharged into by steel work exhaust steam tube, exhaust steam tube height exceedes bleeding valve, greatly reduce the corrosion of steam to blast furnace steel work and equipment, simultaneously because steam condensing reflux decreases discharge and the new water magnitude of recruitment of system of steam.But steam reaches 3.3 at the condensed water pH value of discharge condensing reflux, two blast furnaces were operation about 15 months, and the cylindrical shell of grain slag exhaust steam tube is just because hole appears in corrosion.The water that the formation of hole causes cylindrical shell to include corrosive medium makes a sheer drop from high-altitude.Condensed water has stronger corrosivity to steel work.The corrosion rate of the condensed water leaked down to cylindrical shell is surprising, forms hidden trouble to tubular construction inherently safe.A large amount of percolating water drops on factory building roof and equipment, causes roof panel and equipment to damage because of heavy corrosion.Therefore be badly in need of carrying out technical renewal transformation.For fundamentally solving the cylindrical shell corrosion failure problem of No. one, No. two blast furnace granulated slag exhaust steam tube, spy carries out field, Baosteel one, No. two blast furnace north and south the renovating of totally four grain slag exhaust steam tubes.Original steel exhaust steam tube is abolished, is replaced by glass steel material (FRP pipe) exhaust funnel from+20.00m-+115.000m; Exhaust funnel external diameter is 2.5 meters.The oblique section of exhaust funnel is for be provided with sub-truss across cast house roofing section, and truss support point is newly-increased roofing steel bracket, and interface utilizes periodical repair time interface; The vertical section of furnace roof is connected and fixed by anchor ear and original steel exhaust funnel.But in blast furnace granulated slag exhaust steam tube improvement project, because the FRP pipe changed is for glass fiber material, the conventional construction method cannot setting up springboard by steel-pipe welding temporary support carrys out high-altitude tube connector flange.In addition, if set up fixing platform legs hand cradle to carry out the transformation that grain slag exhaust steam tube is replaced by glass steel material (FRP pipe), it is built and removing and certainly will waste time and energy thereafter, causes a large number of operating expenses.
Therefore knownly set up the method that fixing platform legs hand cradle carries out the replacing of grain slag exhaust steam tube and there is above-mentioned all inconvenience and problem.
Summary of the invention
Object of the present invention, is the detachable operating platform of hood type proposing a kind of blast furnace granulated slag steam discharge cylindrical shell installed on the ground temporarily set up.
Another object of the present invention, be to propose a kind of installation on the ground of temporarily setting up, lift with on glass fiber reinforced plastic exhaust steam tube, complete the Flange joint of upper-lower section glass fiber reinforced plastic exhaust steam tube in high-altitude, and adopt crane dismounting Posterior circle to use the detachable operating platform of hood type of the blast furnace granulated slag steam discharge cylindrical shell of next section of exhaust steam tube.
For achieving the above object, technical solution of the present invention is:
A kind of detachable operating platform of hood type of blast furnace granulated slag steam discharge cylindrical shell, two corresponding semicircular arc-shaped structures are arranged to by the detachable operating platform of hood type, semicircular arc-shaped structure comprises anchor ear Inner arc plate, and anchor ear cylindrical loop-drive and some landing beams, is characterized in that:
Described anchor ear Inner arc plate is made up of circular arc steel plate, and its two ends are provided with junction plate, junction plate are arranged some bolts hole and are furnished with connecting bolt;
Described anchor ear cylindrical loop-drive bends to circular arc by angle bar;
Described platform girder system steel pipe is made, its one end is vertical with anchor ear Inner arc plate upper end welds admittedly, the other end and anchor ear external arc lap welding connect, and at end vertical upwards fixing welding protection railing, the anchor ear Inner arc plate above many landing beams and completely spread steel graticule mesh between anchor ear cylindrical loop-drive; The below of protection railing arranges diagonal brace between anchor ear Inner arc plate lower end.
The detachable operating platform of hood type of blast furnace granulated slag steam discharge cylindrical shell of the present invention can also be further achieved by the following technical measures.
The detachable operating platform of hood type of aforesaid blast furnace granulated slag steam discharge cylindrical shell, wherein said two semicircular arc-shaped structure connecting bolts connect into the detachable operating platform of hood type of a blast furnace granulated slag steam discharge cylindrical shell.
A kind of application of the detachable operating platform of hood type in blast furnace granulated slag steam discharge cylindrical shell renovates of blast furnace granulated slag steam discharge cylindrical shell.
After adopting technique scheme, the detachable operating platform of hood type of blast furnace granulated slag steam discharge cylindrical shell of the present invention has the following advantages:
1, operating platform structure is simple, easy to make;
2, operating platform is installed in tread, and pipeline has docked in high-altitude dismounting, can be recycled;
3, avoid the high-altitude of large-diameter pipeline flange bolt to connect, guarantee the construction safety in high-altitude, accelerating construction progress, reduce engineering cost.
