Description
Technical field
The present invention relates to a kind of structure steel fabrication and installation method, particularly relate to a kind of coke dry quenching boiler shell upper cone and make and installation method.
Background technology
Coke dry quenching boiler shell is the vertical cell body of circular cross-section, and shell is formed by steel plate and section steel manufacture, and middle and top is cone shape, and other is straight tube shape.The furnace shell of existing cone shape makes and installation method makes generally according to veneer reeling machine roll bending ability and on-the-spot steel plate wide point three ~ tetra-circle blanking, and after the layering assembly of ground, then other furnace shells of integral hoisting and coke dry quenching furnace dock.This construction method, steel plate loss big (drawing measuring and calculating loss is 7%), splicing welding joint is many；When layering is assembled, each layer frustum need to be set up temporary weld operating platform when being mutually butted, not only waste time and energy；And because the most of welding job of workmen completes in high-altitude, there is certain potential safety hazard, the construction speed of whole upper cone is affected the biggest.Therefore we make and installation method in the urgent need to a kind of new coke dry quenching boiler shell upper cone, big to solve steel plate loss, improve construction speed.
Summary of the invention
It is an object of the invention to provide a kind of coke dry quenching boiler shell upper cone to make and installation method, the method uses crane the huge sector that raw sheet material level is spliced to be sling, huge sector is uniformly encircled into frustum, it is no longer necessary to set up temporary platform, whole cone one-shot forming, efficiency of construction is high, and the proportion of goods damageds of steel plate the most greatly reduce.
The present invention is achieved in that
A kind of coke dry quenching boiler shell upper cone makes and installation method, comprises the steps:

Step 3, the steel plate in step 2 is welded, form fan-shaped steel plate；
Step 4, suspension centre is set
In the one side of fan-shaped steel plate, one end uniform ring near short arc sets 4 hangers (4 hangers use with fan-shaped steel plate and are welded to connect), and described 4 hangers are followed successively by the first hanger, the second hanger, the 3rd hanger, the 4th hanger；
Second hanger is connected with hoist lifting hook by the first steel wire rope；3rd hanger is connected with hoist lifting hook by the second steel wire rope；First hanger passes sequentially through the first chain block, the 3rd steel wire rope is connected with hoist lifting hook；4th hanger passes sequentially through the second chain block, the 4th steel wire rope is connected with hoist lifting hook；
The length of the first steel wire rope and the second steel wire rope is equal, and the length of the 3rd steel wire rope and the 4th steel wire rope is equal, and the 3rd steel wire rope is than the first length of steel rope；
Step 5, lifting splicing
Being sling by the fan-shaped steel plate being installed on hanger and steel wire rope with crane, crane gradually hooks up, and the second hanger and the 3rd hanger are gradually higher than the first hanger and the 4th hanger, and the first chain block regulates the height of the first hanger, the height of the second chain block regulation the 4th hanger；
After fan-shaped steel plate is sling, suitable for reading adjacent, gradually surround cone；At this moment, the 5th hanger, the 6th hanger and the 7th hanger are welded in fan-shaped steel plate lower inside；Being provided with pulley on described 5th hanger, one end of the 5th steel wire rope is connected with the 6th hanger, and the other end of the 5th steel wire rope is connected by the 3rd chain block and the 7th hanger after pulley；
Operate the 3rd chain block, make fan-shaped steel plate end opening gradually in draw close to adjacent, fan-shaped steel plate forms tapered steel plate；
Fall to taper steel plate make in plane, and by location-plate, taper steel plate is fixed in making plane, make bottom taper steel plate and positive round is formed on top；
Use layout butt joint that taper steel plate opening part is welded, complete the making of coke dry quenching boiler shell upper cone；
Step 6, the coke dry quenching boiler shell upper cone in step 5 is sling, make coke dry quenching boiler shell upper cone dock with coke dry quenching furnace housing straight section, complete the installation of coke dry quenching boiler shell upper cone.
In step 6, coke dry quenching furnace housing straight section and coke dry quenching boiler shell upper cone carry out butt welding after being corrected by wedge, and coke dry quenching boiler shell upper cone connects with top backing ring, and then directly integral hoisting has been welded with furnace shell direct tube section to absolute altitude 28.7m, and furnace shell binds.
Further scheme is: the length of the 3rd steel wire rope is 1.2 ~ 1.5 times of the length of the first steel wire rope.
Further scheme is: described 5th hanger is positioned at the middle and lower part of fan-shaped steel plate, and the 6th hanger is near fan-shaped steel plate left side, and the 7th hanger is near fan-shaped steel plate right edge.
The present invention mainly provides the benefit that: the integral assembling of coke dry quenching boiler shell upper cone the most just can be carried out, it is not necessary to sets up temporary platform, has saved time, manpower and material, has improve work efficiency；Simplify making and the installation of whole coke dry quenching boiler shell upper cone, improve fabrication and installation efficiency of construction；Because the most just completing the integral assembling of coke dry quenching boiler shell upper cone, it is to avoid the work high above the ground in existing method, decrease the potential safety hazard of coke dry quenching boiler shell upper cone fabrication and installation；Coke dry quenching boiler shell upper cone one-shot forming, intensity is high, can improve the service life of coke dry quenching boiler shell upper cone；Sectorial area after coke dry quenching boiler shell upper cone entirety setting-out is very big, and the tiling of whole of steel plate i.e. decreases weld seam quantity, is again downhand welding, and the proportion of goods damageds of steel plate are substantially reduced, and drops to 2.3% from drawing measuring and calculating loss from 7%.
