Description
Technical field
The utility model relates to metallurgy industry ironmaking field of auxiliary, particularly relates to a kind of device for supporting coal rifle changing machine.
Background technology
In blast furnace, coal powder injection is briquet replacing coke, significantly can reduce the problem of coke consumption and ironmaking cost.Wherein coal spouting gun is the tubular unit for connecting between high furnace interior and coal injection, because high furnace interior has the bad working environments of High Temperature High Pressure, the situation that the erosion generation rifle head that coal spouting gun is easy to the wearing and tearing and High Temperature High Pressure being subject to coal dust damages, and rifle head damages the coal spouting gun just needing more to renew.The mode that tradition changes coal spouting gun relies on manpower to be extracted, carry out at high temperature under high pressure owing to extracting coal spouting gun, so, replacing coal spouting gun is abnormally dangerous, particularly utilize when coal spouting gun serious wear and manually can not pull out at all, can only could change coal spouting gun when blast furnace staying, so, the mode of this kind of replacing coal spouting gun can affect blast furnace heat load and stablize, thus reduces ironmaking amount.
Summary of the invention
The purpose of this utility model is to provide a kind of mode utilizing machinery to change coal spouting gun and solves blast furnace heat load instability and reduce the problems such as ironmaking amount for changing the device of coal spouting gun in Zhi Gaolu.
What the utility model proposed comprises two rod members paralleled that the upper surface supported by lift screw mandrel be arranged on flat-bed trailer is respectively arranged with axial recess and the position-limited wheel be arranged in axial recess for changing the device of coal spouting gun in blast furnace, and the plate supported by position-limited wheel be arranged on two rod members, the both sides of this plate are respectively arranged with the toothed track that be connected perpendicular with it, this toothed track is arranged respectively be meshed with it and two pinions be connected by transverse axis, and be provided with manual pulley on the transverse axis of a pinion side.
Described plate is provided with the latch for fixing coal spouting gun.
3-8 position-limited wheel is set in the axial recess of described rod member.
Described lift screw mandrel comprises the screw mandrel arranging female pipe fitting and screw in pipe fitting internal thread, and the upper end of this screw mandrel is provided with handwheel.
The plate in the device changing coal spouting gun in blast furnace that the utility model proposes is provided with the toothed track driven by pinion, thus this plate moving axially at rod member can be made, being arranged on by coal spouting gun on plate to make it extract out from blast furnace or insert, and because driving the power of plate relatively large, so the coal spouting gun of serious wear also can take out by this device; Meanwhile, because the translational speed of plate is relatively very fast, the speed of replacing coal spouting gun can be made to improve.
Accompanying drawing illustrates:
Accompanying drawing 1 is the main TV structure schematic diagram of the device embodiment for changing coal spouting gun in blast furnace that the utility model proposes;
Accompanying drawing 2 is side-views of rod member and plate in Fig. 1;
Accompanying drawing 3 is vertical views of Fig. 1.
Embodiment:
See Fig. 1 to Fig. 3, these three accompanying drawings provide the surface structure schematic diagram of the device embodiment for changing coal spouting gun in blast furnace that the utility model proposes.This device comprises flat-bed trailer 1, lift screw mandrel 2, rod member 3, position-limited wheel 4 and plate 5.
Flat-bed trailer 1 is made up of rectangular plate 11 and four rotor wheels 12 being arranged on this rectangular plate 11 lower surface.Rectangular plate 11 is provided with four lift screw mandrels 2, this lift screw mandrel 2 comprises the pipe fitting 21 being provided with internal thread (not providing in figure) and the screw mandrel 22 screwed in pipe fitting 21 internal thread, and be provided with handwheel 23 in the upper end of each rhizoid bar 22, screw mandrel 22 can be made in the process screwing handwheel 23 to move up or down.Rod member 3 is provided with two, two rod members 3 are disposed on the same plane and parallel, two ends of each root rod member 3 lower surface support by lift screw mandrel 2, the upper surface of each root rod member 3 is respectively arranged with axial recess 31, position-limited wheel 4 is provided with in axial recess 31, this position-limited wheel 4 is the parts for support plate 5, so, position-limited wheel 4 can determine its quantity according to the length of plate 5, under normal conditions, position-limited wheel 4 in each axial recess 31 can be provided with 3-8, optimal selection four position-limited wheels 4.
Plate 5 is the parts for being extracted out from blast furnace by coal spouting gun or inserting, so, the central region of this plate 5 is provided with the channel-shaped portion 51 for limiting coal spouting gun position, and is respectively arranged with toothed track 52 at the two ends of plate 5, and this toothed track 52 can be welded on the both sides of plate 5.The central region of plate 5 is provided with for being meshed mutually pinion 53 with toothed track 52, namely pinion 53 is provided with two, two pinions 53 are fixed on a rotation axis 54, and on a pinion 53, be provided with the manual pulley 55 be meshed with it, and the latch 56 be provided with in the channel-shaped portion 51 of plate 5 for fixing coal spouting gun, due to the parts that this latch 56 is for being fixed on by coal spouting gun on plate 5, so, its quantity can be determined according to the body on coal spouting gun, two latches 56 can be set under normal conditions, 3-6 latch 56 also can be set.
In the process changing coal powder lance for blast furnace, the obliquity handwheel 23 that can be arranged on blast furnace position according to coal spouting gun drives lift screw mandrel 2, to make plate 5 and coal spouting gun in same direction, be then fixed on by coal spouting gun on plate 5, recycling manual pulley 55 drives plate 5.
