The quickly online provision for disengagement of above-mentioned ladle upper nozzle, the rear portion of described pull head is hollow structure, and the front end of air-cooled push rod is inserted in the rear cavity of pull head, and the front end of pull head is discount structure, the front end of pull bar is discount structure, and the discount of pull head is interlockingly connected with the discount of pull bar.
The quickly online provision for disengagement of above-mentioned ladle upper nozzle, it also has pull head clamper, is fixed by pull head gripper after pull head and pull bar snapping, and pull head clamper is positioned at the cavity of bracing frame.
The quickly online provision for disengagement of above-mentioned ladle upper nozzle, it also has mast-up, mast-up to have rotation, traveling, elevating mechanism, and the vertical loading board of mast-up is connected with hollow jack.
The quickly online provision for disengagement of above-mentioned ladle upper nozzle, it also has roller, roller to be arranged on before steel ladle opening on fire-screen door frame, and air-cooled push-rod frame is on roller.
The invention has the beneficial effects as follows:
The present invention uses pull head, pull bar, jack pair ladle upper nozzle to carry out tractive dismounting, the online dismounting of ladle upper nozzle can be rapidly completed, the time pulling out, replacing with the mouth of a river was shortened to current 3 ~ 5 minute by original 20 ~ 30 minutes, substantially increase operating efficiency, it also avoid the damage resistance to material of ladle bottom, reduce stuffing sand addition, add ladle life.The present invention need not overhead traveling crane coordinating operation in operation, has liberated an overhead traveling crane, and the direct motion produced is produced positive meaning, and operation Employee population is reduced to current 4 worker by original 7 ~ 8 simultaneously, has saved human resources, improves the working environment of worker.Design science of the present invention rationally, simple in construction, easy to use, solve the difficult problem changing ladle upper nozzle not solved for a long time, production had the most significant realistic meaning.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Figure mark as follows: cooling duct 1, air-cooled push rod 2, roller 3, ladle 4, pull head 5, filling pipe end 6, bracing frame 7, pull head clamper 8, hollow jack 9, mast-up 10, pull bar 11.
Detailed description of the invention
The present invention is made up of air-cooled push rod 2, roller 3, pull head 5, pull bar 11, pull head clamper 8, hollow jack 9, bracing frame 7, mast-up 10.
Showing in figure, air-cooled push rod 2 is made up of stainless-steel pipe, and a termination cooling duct 1, the other end welds a thin steel column of segment length 40mm, for being connected with pull head 5.Air-cooled push rod 2 frame is on roller 3, and roller 3 is arranged on ladle 4 and wraps before mouth on fire-screen door frame, and air-cooled push rod 2 can penetrate filling pipe end 6 in promoting and pull head 5 is sent into bag on roller 2 and be connected with pull bar 11.
Showing in figure, pull head 5 is made by stainless steel, and hollow one end, one end is solid, and the front end of air-cooled push rod 2 is inserted in the rear cavity of pull head 5, and solid position car goes out discount, for being connected with the discount of pull bar 11 front end.There is the round platform of major diameter at the rear portion of pull head 5, round platform is stuck in the outside of the ladle inner face of filling pipe end 6, the front portion of pull head 5 arrives ladle 4 bottom outside through filling pipe end 6 in ladle 4, and when pull head 5 is pulled out by pull bar 11, filling pipe end 6 is outwards taken out of by the rear portion round platform of pull head 5 together.
Showing in figure, pull bar 11 is through hollow jack 9, and the rear portion of pull bar 11 has screw thread, screw to be spun on the screw thread at pull bar 11 rear portion.The discount of pull bar 11 is interlockingly connected with pull head 5, can the most quickly connect, and the screw-nut of pull bar 11 is used for regulating stroke.
Showing in figure, pull head 5 is gripped by pull head clamper 8 after pull bar 11 snapping.
Showing in figure, bracing frame 7 is between ladle 4 bottom outside and hollow jack 9, and the two ends of bracing frame 7 are in close contact with hollow jack 9 front end with ladle 4 bottom outside respectively, and pull head 5, pull bar 11 and pull head clamper 8 are positioned at the cavity of bracing frame 7.Bracing frame 7 can be stablized and be accurately positioned, and is used for supporting hollow jack 9 drawing recoil and stablizing centering hollow jack 9.
Showing in figure, the vertical loading board of mast-up 10 is connected with hollow jack 9, and mast-up 10 has rotation, traveling, elevating mechanism, and quick for hollow jack 9 is moved.
The course of work of the present invention is as follows:
Bracing frame 7 is fixed in ladle bottom mechanism, moves hollow jack 9 to working position, switch on power；
Pull head 5 is inserted in air-cooled push rod 2 head, and cooling duct 1 opens cooling wind, and air-cooled push rod 2 frame, on roller 3, promotes air-cooled push rod 2 pull head 5 pushes ladle 4 and sends in filling pipe end 6；
Use pull head clamper 8 to interlock fixing by pull bar 11, pull head 5, withdraw from air-cooled push rod 2, and close cooling wind；
Screw on rotating rod 11, to hollow jack 9 head, starts Pu pump and is pulled out by filling pipe end 6；
Pull bar 11, pull head 5 separate, and hollow jack 9 moves to standby position, close power supply, unload bracing frame 7 and pull head 5.
Use the present invention, need operate the most in order, have to check for each equipment tool before using whether normal, confirm that bracing frame 7 is fixing, pull bar 11, pull head 5 connect fixing, pull bar 11 and be connected with hollow jack 9 to fix and restart Pu pump；
Use the duty of middle close attention hollow jack 9, as worked slowly in found hollow jack 9, must close power supply immediately, check pull head 5 whether centering, check hollow jack 9 whether fault, and process in time.
Using the present invention, Employee population is reduced to 4 people by 8 original people, and per tour can save worker 4 people, and the first and second the third fourths four groups save 16 people altogether, and scene has four ladle nozzle provision for disengagement stations, saves 64 people altogether.Work time cost be 200 yuan/man day/.
Work time cost can be saved the whole year: 64 people × 200 yuan/man day × 30/ day month × December/year=460.8 ten thousand yuan/year.
