Abstract
The utility model relate to a fattening device for a taphole mud sleeve of a blast furnace. The fattening device is characterized by comprising a positioning head, a cutter rest and a connection sleeve, wherein the positioning head, the cutter rest and the connection sleeve are connected into a whole body in a welding way; the positioning head is arranged on the upper end surface of the cutter rest and protrudes upwards; at least two cutters are axially distributed and fixed on the upper end surface of the cutter rest by taking the positioning head as a center; the top surfaces of the cutters are provided with cutting edges; a raised mounting platform is arranged on the upper end surface of the cutter rest; the cutters are fixed near the mounting platform on the upper end surface of the cutter rest by bolts in a connecting way; and the connection sleeve is hollow, is matched with the drill rod of an iron notch drill and is driven by the drill rod of the iron notch drill to rotate. Due to the adoption of the fattening, the taphole mud sleeve can be maintained mechanically without being affected in quality so that the operation stability of the iron notch drill can be improved, the quality of the channel of a taphole can be guaranteed and the service lives of the iron notch drill as well the drill rod and the drill bit thereof can be prolonged, and the operator can be far from the severe working environment in a taphole area.
Description
Technical field
A kind of iron mouth mud that the utility model relates to use in metallurgy high furnace ironmaking production technical field overlaps surperficial routine maintenance special implement
Background technology
Existing blast furnace iron notch is after clay gun is blocked up, and the routine maintenance of iron mouth mud cover is smooth by manual mode of carrying out, and when tapping a blast furnace tapping outlet, takes drill for tapping machine directly the iron mouth to be carried out drilling, technical having the following disadvantages:
1, the people safeguards that by hand there is Occupational health harm in iron mouth mud cover.High, the obnoxious flavour enrichment of the temperature of iron port area in production, dust are large, to operator's Occupational health exist harm may, labor intensity is large, the used time is many.
2, the people safeguards that by hand iron mouth mud cover quality is unstable.There is technological disparity in operator's manual upkeep operation, causes the routine maintenance quality of iron mouth mud cover unstable, and then drilling is unstable when affecting tapping outlet, causes iron mouth passage undesired, affects blast furnace and normally taps a blast furnace.
3, affect iron perforater and drilling life of bit thereof.The routine maintenance quality of iron mouth mud cover is unstable, and the iron perforater bit force is inhomogeneous, easily skids, sideslip, and drilling rod is yielding, and the unstable of drilling causes drill bit, rock drill Working environment relatively poor, affects service life of equipment.
The utility model content
The purpose of this utility model just is to provide a kind of blast furnace iron mouth mud sleeve routine maintenance clipper, realize that mud cover smooth after the iron mouth is blocked up safeguard mechanize, make operator away from iron mouth severe environment work area, reduce the harm of labour intensity and Occupational health, improve simultaneously iron perforater and drill bit thereof, drilling rod Working environment, ensure iron mouth quality, improve the stokehold working efficiency.
The technical scheme of employing of the present utility model is: comprise positioning head, knife rest and adapter sleeve soldering group synthetic whole, described positioning head is positioned at the upper surface of knife rest, protrudes upward; The upper surface of described knife rest is fixed with at least two cutters take the center of positioning head as rotating shaft radially distributes, the end face of described cutter is blade; Fixing on described knife rest.
Further: the erecting bed of the projection of the upper surface of described knife rest, described cutter are to be joined with bolts upper surface at knife rest near erecting bed.
Further: described adapter sleeve is hollow shape, and its hollow shape matches with the drilling rod of iron perforater, is rotated by the drilling rod drive of iron perforater.
The utility model has the advantages that:
1, realize that iron mouth mud cover safeguards mechanize, operator can be away from the abominable Working environment of iron port area.
2, the mechanize of iron mouth mud cover is safeguarded and can be guaranteed mud cover maintenance quality, improves the stability of iron perforater operation, guarantees the iron notch channel quality, extends iron perforater and drilling rod thereof, drilling life of bit.
Description of drawings
Accompanying drawing is used for illustrating embodiment of the present utility model.
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is vertical views of accompanying drawing 1.
Accompanying drawing 3 is A-A sectional views of accompanying drawing 1.
Accompanying drawing 4 is B-B sectional views of accompanying drawing 2.
Embodiment
In accompanying drawing, each parts detail is as follows: 1, positioning head, 2, cutter, 3, bolt, 4, knife rest, 5, adapter sleeve
Positioning head 1 of the present utility model, knife rest 4 are welded into integral body with adapter sleeve 5, and described positioning head 1 is positioned at the upper surface of knife rest 4, protrudes upward; The upper surface of described knife rest 4 is fixed with at least two cutters 2 take the center of positioning head 1 as rotating shaft radially distributes, the end face of described cutter 2 is blade; Fixing on described knife rest 4.The erecting bed of the projection of the upper surface of described knife rest 4, described cutter 2 is to be joined with bolts in the upper surface of knife rest 4 near erecting bed, realizes the moment of torsion transmission.Positioning head 1 and cutter 2 act on mud and put realization location and cutting function by the moment of torsion that adapter sleeve 5 knife rests 4 pass over; Described adapter sleeve 5 is hollow shape, and its hollow shape matches with the drilling rod of iron perforater, is rotated by the drilling rod drive of iron perforater.
Principle of work of the present utility model is: the drilling rod of iron perforater drives adapter sleeve 5 and rotates, make cutter 2 follow rotation, positioned by positioning head 1, the end face blade of cutter 2 rotates and carries out drilling, because cutter is radially symmetrical, during rotation the shear action of blade is stable, can not skid, sideslip, and drilling rod is not yielding.
