Description
Technical field
The utility model belongs to the converter smelting mechanical means, is specifically related to a kind of quick replacement device of mammoth conveter oxygen rifle.
Background technology
At present, oxygen converter steelmaking is in critical role in various method for making steel in the world, and the oxygen rifle is one of main mechanical of oxygen converter steelmaking.Usually the oxygen rifle is set to two covers, and a cover is online to be used, and another set of the maintenance at guard position awaited orders.Because the operating environment of oxygen rifle is abominable, the work-ing life of oxygen rifle is very short, changes more frequent.Therefore, the time length of oxygen rifle replacing will directly affect normal production and the output height of converter.Only take 260 ton large-scale converters as example, oxygen rifle body diameter phi 402mm, long 24m, shower nozzle are ZT402-6, oxygen rifle upper hose, oxygen pipe adopt counterpart flange associated mode to be connected with metallic hose.Oxygen rifle adjusted design is 3 of the lower ends adjustment of oxygen rifle.
Existing oxygen rifle oxygen pipe, water inlet pipe and water outlet pipe, oxygen metallic hose and water metallic hose all adopt flange connect, need dismantle 40 support bolts during dismounting oxygen rifle, change new oxygen rifle and need again screw 40 support bolts again, and the square flange counterpart need be adjusted contraposition, cause thus the oxygen rifle replacing time long, labor strength is large, transfers the rifle difficulty.5 ~ 6 hours oxygen rifle activity durations needed 5 ~ 6 filling times, made the single rifle production of converter reach 40 ~ 48 hours, in case another oxygen rifle breaks down, converter will stop production immediately.In addition, because the point of tangent of oxygen lance lifting bogie overlaps with the dolly center of gravity, very easily cause to lay particular stress on and car wheel occurs and gnaw the rail phenomenon.
Summary of the invention
The purpose of this utility model is the deficiency that exists for above-mentioned prior art, and a kind of reasonable in design, fabrication and installation are convenient, effect is good converter oxygen gun quick replacement device are provided.
For this reason, the technical solution of the utility model is:
The converter oxygen gun quick replacement device comprises oxygen rifle dolly, and water inlet key seat, oxygen pin boss, backwater key seat, hemisphere pit, guide finger, oxygen gun bracket, sealing groove and the sealing-ring of being clapped and be arranged at respectively bat up and down, the end end of by are formed; Clap by the upset bolt and be fixed on the collar tie beam of oxygen rifle dolly at the end; Water inlet key seat, oxygen pin boss and backwater key seat are set up in parallel a side of clapping the end of in, and its upper end is reserved with respectively sealing groove, and inserts sealing-ring; Water inlet key seat and backwater key seat inboard respectively are provided with a guide finger; The opposite side that clap at the end has down " U " shape oxygen carriage, has half ball impression on the square plate of bottom and cheats.
Described water inlet key seat, oxygen pin boss and backwater key seat are three stainless steel tubes with bore to be welded on end bat corresponding aperture form, and it is highly 300-500mm.Reserving is highly generally to determine according to the thickness of caliber, and caliber is thicker highly higher, otherwise relatively shorter, but can not be too short, in order to avoid unstability or affect sealing effectiveness.
Described guide finger is the cylinder taper type, is highly 500-700mm.Guide finger mainly be arranged on the oxygen rifle on guide path coordinate so that accurately locate during grafting oxygen rifle.
Described hemisphere pit is arranged on the end to take section, and the protruding ball on pit and oxygen rifle is complementary, the spherical joint that formation can be adjusted flexibly.
The utility model has overcome the deficiency that prior art exists, and has following advantage:
1. owing to adopting whole substitute mode of pegging graft, make the replacing time of oxygen rifle shorten to 30 minutes by original 5 ~ 6 hours, change efficient and convenient.Namely save the activity duration, alleviate again workman's labour intensity, for enterprise wins considerable economic benefit.
2. because oxygen rifle dolly is connected by spherical joint on dolly with the oxygen rifle, has realized that the oxygen rifle can be vertical with fire door under any state, and can arbitrarily adjust, easy and simple to handle.
3. because apparatus structure is reasonable in design, namely solved the problem that hang arms rear oxygen rifle and dolly are laid particular stress on, avoided again causing by laying particular stress on dolly to gnaw the generation of track phenomenon.

Fig. 2 is the vertical view of converter oxygen gun quick replacement device.
In figure: the end, clap 1, water inlet key seat 2, oxygen pin boss 3, backwater key seat 4, hemisphere pit 5, guide finger 6, oxygen gun bracket 7, oxygen rifle dolly 8, sealing groove 9, sealing-ring 10.
Embodiment
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in detail:
The converter oxygen gun quick replacement device, as attached illustrated in figures 1 and 2, emphasis is to make the end to clap.Clap 1 at the bottom of making a thick box-shaped of 200mm by size, it is made and presses the cased beam making with proof strength.Get out the circular hole of two φ 273mm, a φ 402mm on the same axis of one side.Opposite side cuts out " U " shape oxygen bracket slot of oxygen gun bracket 7 according to oxygen rifle diameter.Secondly, the square steel plate that is drilled with hemisphere pit 5 is welded in the bat appropriate location parallel with oxygen rifle medullary ray, 1 bottom, the end.Internal diameter size according to oxygen hose and water pipe on the oxygen rifle, and be complementary with this internal diameter size, the heavy wall stainless steel tube of two φ 273mm of the sealing groove 9 selecting in advance and process, φ 402mm, a long 400mm is welded in respectively the position of clapping three circular holes that bored on 1 top in the end, forms water inlet key seat 2, backwater key seat 4 and oxygen pin boss 3.The guide finger 6 that in water inlet key seat 2 and the inboard of backwater key seat 4, a termination section is processed into respectively the φ 120mm of cylinder taper type, long 600mm is welded in end bat 1.Then clap the position in 1 bottom water inlet, backwater and oxygen pin boss hole the end of at and install respectively the ring flange identical with this aperture, ring flange is by the connection by metal hose of bolt and external oxygen G﹠W.At last, " O " shape sealing-ring 10 is placed in the sealing groove 9 of water key seat 2, backwater key seat 4 and oxygen pin boss 3.1 use nut is clapped at the end is fixed on the upset bolt of being located on oxygen rifle dolly 8 collar tie beams, make its can with the together up-and-down movement of oxygen rifle dolly.
Can use after the utility model fabrication and installation.During operation, after the oxygen rifle falls within on oxygen gun bracket 7, due to the position-limiting action of oxygen gun bracket 7, thereby can easily the guide path on the oxygen rifle be imported guide finger 6, water inlet pipe, oxygen hose and return water pipe centering that guide finger 6 is guided again on the oxygen rifle are located.Because the internal diameter of the water inlet pipe on the oxygen rifle, oxygen hose and return water pipe is slightly larger than into the external diameter of water key seat 2, oxygen pin boss 3 and backwater key seat 4, therefore can the water inlet pipe on the oxygen rifle, oxygen hose and return water pipe be inserted in the water inlet key seat 2 that is arranged in end bat 1 very wellly, on oxygen pin boss 3 and backwater key seat 4, thereby realize whole grafting fast, and complete the conveying function of oxygen G﹠W under the effect of sealing-ring 10.When changing the oxygen rifle, only need the oxygen rifle is inserted in into water key seat 2, the oxygen hose on oxygen pin boss 3 and backwater key seat 4 and water pipe are extracted and got final product, and need not demounting bolt, and be namely easy to be quick again.
