Abstract

The utility model discloses a tool for quickly processing an iron notch mud sleeve, which comprises a tapping machine drill rod and a disc, wherein one end of the drill rod is fixedly provided with a main drill, the drill rod passes through and fixedly connected with the disc, circular holes are uniformly distributed on the disc, the circular holes are fixedly connected with a connecting bolt, and the other end of the connecting bolt is fixed with a sub drill. The utility model can reduce the labor intensity of workers and has high processing efficiency when being used for processing the mud sleeve.

Description

A kind of instrument of fast processing iron mouth mud cover

Technical field

The utility model relates to a kind of instrument of fast processing iron mouth mud cover.

Background technology

Important channel when metallurgy industry blast furnace ironmaking iron mouth mud cover is blast furnace casting, domestic general use refractory material casting moulding at present or ramming process, work-ing life is lower.Matching used with it blast furnace gun also is the important tool of stokehold, is mainly used in the later stage of tapping a blast furnace to block up.If can not normally block up, will cause blast furnace checking even damping down, lead to a disaster, bring enormous economic loss.And blast furnace will be realized blocking up normally, and treatment facility need be safeguarded, and outside guaranteeing to run well, key effect is also played in the processing of iron mouth mud cover.Because in use, iron mouth mud cover occurs damaged through regular meeting, and unrestrained scum etc. is arranged, can not be normally when blocking up and the big gun head of clay gun fit like a glove, cause stemming can not well push iron mouth passage, influence the effect of blocking up.At present, when iron mouth mud cover is handled, generally be manual operation, at first use pneumatic pick that the refractory materials around the iron mouth mud cover is cut a hole the dell that becomes to be about as much as the big gun head shapes, the shape of this dell is very irregular, also needs finishing; And then add new refractory materials, and start clay gun and extrude a profile accurately to iron mouth place, clear up once more and proofread, so need just can finish for 3～4 times repeatedly.This process generally needs about 30 minutes, and the time is long, and working strength of workers is also bigger.And because the rhythm of production anxiety, the workman often can't patient processing, does not reach standard-required, causes size deviation bigger, can't realize normally blocking up.

The utility model content

The technical problems to be solved in the utility model provides a kind of instrument of fast processing iron mouth mud cover, and it can reduce labor strength, and the processing efficiency height.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of instrument of fast processing iron mouth mud cover, it comprises a taphole drilling machine drilling rod, be fixed with main drill bit at described drilling rod one end, it also comprises a disk, and described drilling rod passes disk and affixed, is evenly equipped with circular hole on described disk, the place is fixed with joint bolt at described circular hole, is fixed with the branch drill bit in the other end of joint bolt.

Preferably, above-mentioned main drill bit and branch drill bit are alloy bit; Preferably, above-mentioned disk and drilling rod welding.

Preferably, above-mentioned circular hole is four; Above-mentioned joint bolt is a trapezoidal thread.

Adopt the beneficial effect that technique scheme produced to be: to adopt this instrument that iron mouth mud cover is handled, only need once check and correction just can finish, about general 10 minutes times spent, improved efficiency greatly; Utilize the drilling rod of taphole drilling machine to advance, alleviated working strength of workers; Adopt the utility model to help to realize normalizing operation, avoid overlapping situations such as off centering because of artifact causes iron mouth mud.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the synoptic diagram of disk among Fig. 1;

Wherein, 1 represents drilling rod, and 2 represent disk, and 3 represent joint bolt, and 4 representatives divide drill bit, and 5 represent circular hole, the main drill bit of 6 representatives.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Referring to accompanying drawing 1 and accompanying drawing 2, the utility model is finished by existing taphole drilling machine, use existing electronic, pneumatic or hydraulically powered taphole drilling machine all can, the drilling rod on the taphole drilling machine because of the taphole drilling machine model is different may be different, but as long as and disk 2 firm welding.At distance taphole drilling machine drilling rod 1 front end 150mm place, disk 2 of weldering system, this disk 2 is a steel disc, thickness is 20mm, firm welding.Be evenly equipped with four circular holes 5 on the disk 2, be used for fixing joint bolt 3, this joint bolt adopts trapezoidal thread, is used for installing drill bit.Carry main drill bit 6 on the drilling rod 1.Drill bit herein uses the alloy bit effect relatively good.

During use, the drilling rod 1 of the band disk of making 2 is installed on the taphole drilling machine, makes intermediary master drill bit 6 aim at the Tie Kou center, all the other four branch drill bits 4 are tangent with cylindrical.Bore moving drilling rod 1, and slowly push ahead, hard refractory matter under the rotation of disk 2, is a plane generally big or small with clay gun big gun head diameter by the drill bit cutting just around the iron mouth mud cover.Continue to promote drilling rod, the plane continues to advance, and when reaching degree of depth 100mm, stops operating, and this iron mouth mud cover just comes out to have finished like this.The alloy bit that uses in the utility model was changed once in general 5 days, and consumption is very little.Adopt the utility model can make stokehold class Three realize normalizing operation, reduce artificial factor.
