Abstract
The invention relates to a construction method for lifting carbon bricks at the blast furnace bottom, which belongs to the technical field of blast furnace bottom masonry construction. The construction method comprises the following steps: making a lifting beam (1) from seamless steel pipes; both ends of the upper surface of the lifting beam (1) are welded with two upper palm plate lifting rings (2), and both ends of the lower surface of the lifting beam (1) are welded with four lower palm plate lifting rings (3); upper buckles (4) are installed by utilizing the lower palm plate lifting rings (3) on the two ends of the lifting beam (1), a wire rope (5) is hung on each buckle (4), and an expandable lifting tool (6) is hung on the lower end of each wire rope (5) by the buckle (4), thereby achieving the lifting conditions for lifting the carbon bricks; and the expandable lifting tool (6) is inserted into a lifting hole in a carbon brick (7) at the furnace bottom, and an electric hoist is lifted to lift the carbon brick (7), thereby completing the lifting of the carbon brick at the furnace bottom. The invention solves the problems of backward technique, unstable lifting, easy rotation of carbon bricks, easy collision with carbon brick edges, and the like, accelerates the construction progress, shortens the construction period and enhances the work efficiency.
Description
Technical field
The invention belongs to carbon bricks at blast furnace bottom building construction technical field, the handling method that particularly relates to a kind of carbon bricks at blast furnace bottom building construction, be particularly useful for that blast furnace is newly-built, in enlarging and the overhauling reform engineering, during the carbon bricks at blast furnace bottom building construction, the handling of furnace bottom carbon brick.
Background technology
When the carbon bricks at blast furnace bottom building construction, the handling method that is adopted generally is at present: utilize steel rope directly to fasten and hang vacuum cup handling carbon brick.Be earlier with two vacuum cups during use, be buckled on the carbon brick surface that the extension steel rope is directly fastened in the top of vacuum cup; , make after sucker is adsorbed on the carbon brick surface the air sucking-off in the vacuum cup by vacuum pump, utilize hoist ceiling crane that carbon brick is sling, pile up assigned address.
The method that adopts above-mentioned traditional handling carbon brick to build by laying bricks or stones exists following problem: utilize steel rope directly to fasten the extension suspender, the original backwardness of technology can not satisfy the big needs of producing of modernization; In the handling process, not steady, carbon brick rotates easily, the corner angle of the carbon brick that causes easily colliding with; Vacuum cup matching used hose, cable can cause certain winding at the construction field (site), form chaotic, have potential safety hazard, be unfavorable for building construction.
Summary of the invention
The object of the present invention is to provide a kind of construction method of lifting carbon bricks at blast furnace bottom.Adopt " balance sling " handling furnace bottom carbon brick, the technology that has solved traditional handling carbon brick existence falls behind, handling is not steady, carbon brick easily rotates, collides with easily problems such as carbon brick corner angle, has accelerated construction speed, has shortened the construction time spent, has improved work efficiency.
" balance sling " is made up of hanging beam, palm plate suspension ring, buckle, steel rope, expansion suspender etc.Make simple, easy to use, volume is little, easy to operate.
The technical scheme steps that adopts:
(1) utilize solid drawn pipe to make hanging beam.
(2) end positions on hanging beam is welded two and is gone up four of palm plate suspension ring and the welding of the end positions below hanging beam palm plate suspension ring down.
(3) below hanging beam, slap under the two ends on the plate suspension ring, buckle and steel rope are installed, utilize buckle to hang up the expansion suspender in the lower end of steel rope.
(4) with the expansion suspender, be inserted in the hole for hoist of furnace bottom carbon brick, the electric block that the hoists carbon brick of slinging is finished the handling of furnace bottom carbon brick.
In step (4) construction, at first the expansion suspender is inserted in the hole for hoist of furnace bottom carbon brick, electric block hoists, when the steel rope of " balance sling " is tightened, the taper pull bar of expansion suspender with on carry, sleeve-shaped expansion blade is outwards expanded and the bloated jail of carbon brick lifting hole(eyelet) hole wall, at this moment carbon brick steadily can be sling, reach the purpose of handling.
The invention has the beneficial effects as follows: in the lifting carbon bricks at blast furnace bottom process, adopt " balance sling " handling carbon brick, less investment, make simple, handling is steadily easy to operate, solved the drawback that rope twines, and has improved work efficiency, has shortened the engineering time that carbon bricks at blast furnace bottom is built by laying bricks or stones.

Palm plate suspension ring scheme drawing on Fig. 2.
Fig. 3 is palm plate suspension ring scheme drawing down.
Specific implementation method
Below in conjunction with embodiment of the present invention is described shown in specific implementation method and the figure:
The technical scheme steps that adopts:
(1) utilize solid drawn pipe to make hanging beam 1.
(2) end positions on hanging beam 1 is welded two and is gone up palm plate suspension ring 2 and plate suspension ring 3 are slapped in four of the welding of the end positions hanging beam 1 below down.
(3) below hanging beam 1, slap under the two ends on the plate suspension ring 3, buckle 4 and steel rope 5 are installed, utilize buckle 4 to hang up expansion suspender 6 in the lower end of steel rope 5.
(4) with expansion suspender 6, be inserted in the hole for hoist of furnace bottom carbon brick 7, the electric block that the hoists carbon brick 7 of slinging is finished the handling of furnace bottom carbon brick.
1, " balance sling " blanking is made
(1) hanging beam: utilize solid drawn pipe to be made.
(2) palm plate suspension ring: thickness is the steel plate of δ=16mm, as slapping the plate suspension ring up and down.Amount to 6.
(3) upward slap the plate suspension ring with two and be welded on " balance sling " top two-end part, slap the plate suspension ring down with four and be welded on " balance sling " following two-end part.
2, prepare before " balance sling " used
Go up palm plate suspension ring, and hang on the hook of hoist ceiling crane for two with silk rope pinning " balance sling "; On the following palm plate suspension ring at " balance sling " two ends, hang up buckle and steel rope, the lower end of steel rope hangs up the expansion suspender with buckle.Dead work is finished, and reaches usage condition.
3, " balance sling " used
(1) at first uses electric block to sling " balance sling ", make two ends steel rope and expansion suspender vertically downward.
(2) the expansion suspender is inserted in the hole for hoist on plane on the furnace bottom carbon brick, and inserts it into and put in place, that is: the plane baffle ring of expansion suspender and carbon brick plane are harmonious, and must not leave the slit.
(3) electric block that hoists stops when steel rope is tightened, and whether the expansion blade of checking the expansion suspender distending, whether expand firm with furnace bottom carbon brick hole for hoist, after confirming that expansion blade distending is errorless, open electric block once more, at this moment " balance sling " the furnace bottom carbon brick that plays steadily rises.
(4) after the furnace bottom lifting carbon bricks is arrived the desired location, slowly carriage return falls and it is piled up to putting in place gently.
(5) confirm carbon brick pile up put in place errorless after, electric block continues carriage return, loosens steel rope.After steel rope loosens, make the expansion blade retraction of expansion suspender, and with furnace bottom carbon brick hole for hoist radial separation.At this moment the expansion suspender is taken out from furnace bottom carbon brick hole, just finished the handling of furnace bottom carbon brick.
