Description
Technical field
This utility model relates to blast furnace tuyere small sleeve dismounting dolly, belongs to blast furnace maintenance equipment technical field.
Background technology
Blast furnace mainly by air inlet system, feeding system, hot-air system, cooling system, tap a blast furnace slag-tapping system, injection system etc.
Composition.Tuyere small sleeve is the equipment in air inlet system, fine copper casting form, circular cone tubular, inner hollow, and water flowing cools down.Peace
During dress, external diameter rear end is overlapped bright finish with air port two and is connected, and internal diameter outer end is connected with blowpipe sphere, and the inner is stretched into inside blast furnace, and bottom has
Holding device；High-temperature oxygen-enriched air and coal dust that blast furnace process needs mix at blowpipe end, enter by tuyere small sleeve front end
Inside blast furnace, with the chemical reaction that coke carries out fierceness, release substantial amounts of heat, thermic load during therefore tuyere small sleeve is blast furnace process
The equipment concentrated most, is easily damaged.
When changing tuyere small sleeve, after little set being beaten pine by sliding hammer, traditional way is that little set is lifted by 6 to 8 people with crowbar
Extract air port two after Qiing out to overlap, less for fresh wind port set is lifted feeding air port two by many people and overlap interior, but due to by working space
Narrow and small impact, wastes time and energy the process that little set is extracted out and sent into very much, it is therefore necessary to a kind of equipment of invention, improves and changes
The operation technique of tuyere small sleeve.
Utility model content
Technical problem to be solved in the utility model is to provide blast furnace tuyere small sleeve dismounting dolly, can be convenient, fast complete
Become the dismounting of tuyere small sleeve, solve background technology problem.
The technical scheme solving above-mentioned technical problem is:
Blast furnace tuyere small sleeve dismounting dolly, the wheel including wheel shaft, being installed on wheel shaft two ends and being fixed in the middle part of wheel shaft
Crowbar, crowbar is mutually perpendicular to wheel shaft.
Above-mentioned blast furnace tuyere small sleeve dismounting dolly, described crowbar end is fixed with action bars, and steady pin, operation are installed in front end
Bar is vertical with crowbar respectively with steady pin；The bearing of crowbar and wheel shaft to the distance of crowbar end more than bearing to crowbar before
The distance of end.
Above-mentioned blast furnace tuyere small sleeve dismounting dolly, described crowbar end is fixed with action bars, and steady pin, operation are installed in front end
Bar is vertical with crowbar respectively with steady pin；It also includes support, and pedestal upper end is fixed with crowbar, fixes in the middle part of lower end and wheel shaft,
The bearing of crowbar and support to the distance of crowbar end more than the distance of bearing to crowbar front end.
When using this utility model dismounting tuyere small sleeve, before this utility model is pushed into tuyere small sleeve to be removed, will sled
Thick stick stretches in tuyere small sleeve with one end of steady pin, determines when tuyere small sleeve is all enclosed within crowbar and crosses steady pin, two people
Depression bar, levers up tuyere small sleeve, and other two people or a people rotate wheel and be moved rearwards by, and are split out by tuyere small sleeve；Load
During tuyere small sleeve, crowbar is stretched in the little set of fresh wind port with one end of steady pin, determines that tuyere small sleeve is all enclosed within crowbar also
When crossing steady pin, two people's depression bars, little for fresh wind port set is levered up, other two people or a people rotate wheel and move forward,
It is sent to air port two and overlaps interior.
The beneficial effects of the utility model are:
This utility model, equipped with wheel, conveniently moving, utilizes lever principle to operate, and three to four people just can be light
Tuyere small sleeve is levered up, tuyere small sleeve is extracted out or is sent into air port two and overlaps, complete the disassembling operations of tuyere small sleeve.This utility model
Simple in construction, with low cost, time saving and energy saving, convenient, fast can complete the dismounting of tuyere small sleeve.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is the side view of Fig. 1；
Figure is labeled as: wheel 1, wheel shaft 2, crowbar 3, action bars 4, support 5, steady pin 6.
Detailed description of the invention
Fig. 1 and Fig. 2 shows, this utility model includes wheel shaft 2, is installed on the wheel 1 at wheel shaft 2 two ends, crowbar 3 and support 5,
Support 5 is one piece of rectangular slab, and the middle part of wheel shaft 2 is fixed on the base of rectangular slab, and top margin is fixed with the crowbar 3 vertical with wheel shaft 2；
The end of crowbar 3 is fixed with action bars 4, facilitates maintainer to exert a force；Steady pin 6 is installed in front end, be used for preventing tuyere small sleeve from
Slip on crowbar；Action bars 4 is vertical with crowbar 3 respectively with steady pin 6；The bearing of crowbar 3 and support 5 is to crowbar 3 end
Distance, more than the distance of bearing to crowbar 3 front end, forms a laborsaving lever construction.
When using this utility model dismounting tuyere small sleeve, before this utility model is pushed into tuyere small sleeve to be removed, will sled
Thick stick 3 stretches in tuyere small sleeve with one end of steady pin 6, determines when tuyere small sleeve is all enclosed within crowbar 3 and crosses steady pin 6,
Two people's depression bars 4, lever up tuyere small sleeve, and other two people or a people rotate wheel 1 and be moved rearwards by, and are torn open by tuyere small sleeve
Go out；When loading tuyere small sleeve, crowbar 3 is stretched in the little set of fresh wind port with one end of steady pin 6, determines that tuyere small sleeve all overlaps
At crowbar 3 and when crossing steady pin 6, two people's depression bars 4, little for fresh wind port set is levered up, other two people or a people rotate car
Wheel 1 moves forward, and is sent to air port two and overlaps interior.
