C. use chain block lifting blast furnace cooling stave in stove, then unclamp top hoist and the steel wire rope of layback hoist engine；
D. use the outer chain block of two stoves through the cooling wall water pipe hole on blast furnace furnace wall and cooling wall bolt outside blast furnace
The parallel pulling in hole blast furnace cooling stave, the cooling water pipe of blast furnace cooling stave is solid by cooling wall bolt hole after entering cooling wall water pipe hole
Determine blast furnace cooling stave；
E., in next block blast furnace cooling stave entrance State of Blast Furnace is drawn in top hoist lifting, step b, step c, step d are repeated, will
Next block blast furnace cooling stave is installed and is put in place, completes one by one blast furnace cooling stave integral installation according to above-mentioned steps.
The collaborative hanging method of above-mentioned blast furnace cooling stave, in the stove in State of Blast Furnace in described step a, coaster has 4, point
Not being arranged on the circumference of blast furnace inwall, their spacing is equal.
The collaborative hanging method of above-mentioned blast furnace cooling stave, in the stove in State of Blast Furnace in described step a, chain block is many
Individual, they lay respectively at above the installation site of every piece of blast furnace cooling stave, and the outer chain block of the stove installed outside State of Blast Furnace is respectively
Relative with the cooling wall water pipe hole of every piece of blast furnace cooling stave and cooling wall bolt hole.
The collaborative hanging method of above-mentioned blast furnace cooling stave, puts down with the outer different work of blast furnace in operating personnel is scattered in blast furnace
Platform, operating personnel uses radio communication contact information to keep in touch at any time, it is ensured that operation is smooth and easy.
The invention has the beneficial effects as follows:
The present invention is respectively provided with top hoist and layback hoist engine at blast furnace roof and stokehold, utilizes top hoist and coaster
By in blast furnace cooling stave traction to stove, in layback hoist engine and stove, draw blast furnace cold with chain block, the outer chain block of stove
But wall to mount point is fixed installation, and the contact in installation process uses wireless connections mode, keeps in touch unobstructed.
The present invention is the innovation of blast furnace cooling stave mounting technique, use simple apparatus to solve for a long time not solve
Medium and small blast furnace maintenance lifts a difficult problem for blast furnace cooling stave.The present invention can be to reduce traditional work mode crane, to arrange subring
The facility expenses such as beam, are not required to remove furnace top equipment, reduce operating personnel's labor intensity, operating flexibility, and safety is high, is effectively improved
Working performance.
Accompanying drawing explanation
Fig. 1 is the lifting schematic diagram of the blast furnace cooling stave of the present invention；
Fig. 2 is the traction scheme of installation of the blast furnace cooling stave of the present invention.
In figure, labelling is as follows: coaster 4, stove outer coaster 5, stove in top hoist 1, furnace roof coaster 2, layback hoist engine 3, stove
