Description
Technical field
The utility model is related to blast furnace technical field of auxiliary equipment in smelting iron, and specifically provide a kind of blast furnace replacement rock drill
Lift trolley.
Background technology
Currently, the new No.1 4747m of this steel3Blast furnace is one of domestic super-huge blast furnace, 4 cast houses is shared, due to plane
Space is limited, and Hydraulic clay gun and iron notch drill are arranged in the same side of iron runner, and two Equipment Foundations positions are clipped in wind at a distance of relatively close
Between mouthful platform and cast house plateform frame structure, this arrangement form saves stokehold plane space very much, but plant maintenance
Solid space is smaller, increases upkeep operation difficulty.
In addition, rock drill is hung upside down on iron notch drill crossbeam, when replacing rock drill in the past, stokehold overhead traveling crane can't reach, crane
Into not going, fork truck is also lifted not in place, can only be worker's chain block, rock drill being removed to tuyere platform and go out bit by bit
Between the platform of iron field, then it is lifted on truck and is transported with overhead traveling crane.It replaces a rock drill and needs 5.5 hours, it is time-consuming, laborious, it is past
Toward because rock drill cannot be replaced in time, cause iron mouth that cannot open in time and influence blast furnace and normally tap a blast furnace.
In addition, if blast furnace iron notch cannot be opened in time, there are a large amount of slag irons in cupola well, it is suitable by conditions of blast furnace is influenced
Row, can cause blast furnace to be suppressed, not receive air quantity.Untouchable rising causes air port burn-through accident in cupola well, once air port is burnt, due to
There are a large amount of slag irons in cupola well, when checking often results in Slagging, brings about great losses to blast furnace.
Utility model content
In order to solve the above-mentioned technical problem, the utility model, which provides a kind of blast furnace and replaces rock drill, lifts trolley, with solution
Certainly the problem of blast furnace normally taps a blast furnace is influenced because rock drill cannot be replaced in time in the prior art.
The utility model is realized in this way a kind of blast furnace, which replaces rock drill, lifts trolley, including lift tablet, cartridge type subtracts
Device, hydraulic jack, support tablet and universal wheel are shaken, telescopic shock absorber is equipped with 4, and the upper end of 4 telescopic shock absorbers is fixed
At 4 angles for lifting tablet, lower end is fixed at 4 angles of support tablet, is supported and is fixed two hydraulic jacks on tablet,
Universal wheel is equipped with 4, is connected at 4 angles of support tablet lower surface.
Further, the telescopic shock absorber includes guide rod, spring and outer barrel, guide rod connecting spring, lower spring end
Be fixed in outer barrel, the upper end of guide rod be fixedly connected it is described lift tablet, support tablet described in the fixed-link of outer barrel lower end.
Further, described to lift the hot rolled steel plate that tablet is thickness 16mm；The heat that the support tablet is thickness 20mm
Rolled steel plate.
Further, it is 350mm that the highest for lifting tablet, which lifts height,.
Further, a length of 1300mm for lifting tablet, width 700mm, the height for lifting trolley are
780mm。
Compared with prior art, the utility model has the advantage of：
1, simple in structure, specificity is strong, and 3 times of work efficiency or more can be improved in checking maintenance, easy to use；
2, very narrow working space can be crept into, in the case where the advanced hoisting machinery of any high-tech is unattainable,
Can be 1.8 tons weight, it is 1.2 meters long, the rock drill on blast furnace open hole machine is hung upside down, from tuyere platform and cast house platform
It removes or moves into crack；
3, time saving, laborsaving, it replaces a rock drill and only needs 1 hour, mitigate labor intensity, it is empty to can avoid multiplexing kind
Between the security risk brought of cross-operation；
4, itself has independent hydraulic power unit, need not install feed cable or contact electric installation；
5, freedom of action, under its elevating capacity and appearance and size admissible condition, can in entire blast furnace table or
The lifting work of the overwhelming majority is undertaken in crack；
6, the fixed structures such as overhead track are not needed, therefore capital expenditure, production cost or maintenance cost can be made to reduce.
Description of the drawings
Below in conjunction with the accompanying drawings and embodiment is described in further detail the utility model：
FIG. 1 is a schematic structural view of the utility model.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with the accompanying drawings and implement
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model is not used to limit the utility model.
With reference to figure 1, the utility model, which provides a kind of blast furnace, to be replaced rock drill and lifts trolley, including lift tablet 1, cartridge type subtracts
Shake device 2, hydraulic jack 3, support tablet 4 and universal wheel 5, telescopic shock absorber 2 is equipped with 4, and 4 telescopic shock absorbers 2 is upper
End is fixed at 4 angles for lifting tablet 1, and lower end is fixed at 4 angles of support tablet 4, is supported and is fixed two liquid on tablet 4
It presses jack 3, universal wheel 5 to be equipped with 4, is connected at 4 angles of 4 lower surface of support tablet.
When needing to remove old rock drill, is shifted onto below iron notch drill trolley is lifted, back and forth pull hydraulic jack 3
Crank makes hand oil pump pressure oil constantly into oil cylinder, since the continuous of oil pressure increases in oil cylinder, piston promotion is forced to lift tablet
1 moves upwardly together, and when lifting tablet 1 and being close to rock drill, dismantles rock drill fastening bolt, then opens hydraulic jack 3
Oil return valve, in-oil cylinder high pressure oil just flow back to shoe cream room, and then rock drill forces and falls on original position under piston.Lift trolley release
Then narrow space is directly sling old rock drill with overhead traveling crane and is fallen on truck and transports.
Similarly, when needing to install new rock drill, first, handlebar new rock drill in day, which is lifted into, to be lifted on trolley, is lifted small
Vehicle is shifted onto below iron notch drill, and new rock drill is installed in place with same method.
