Abstract
The utility model provides an iron notch drill of high reliability, belongs to metallurgical equipment technical field, the purpose of design is that the strike axle that prevents iron notch drill burns out, its technical scheme is, during this iron notch drill constitutes including the iron notch drill body with prevent the splash device, prevent that the splash device includes guard plate and suspended beam, suspended beam fixes the top at the drilling rod of iron notch drill body, the guard plate is hung in suspended beam's lower part, and the drilling rod of iron notch drill body passes from the centre bore of guard plate, leaves between guard plate and drilling rod and prevents bumping the clearance. The utility model discloses the sediment iron that utilizes the guard plate to stop mouthful back splash of blast furnace division iron prevents that high temperature sludge iron from burning the strike axle, has lengthened the life who hits the axle greatly, has reduced iron notch drill's cost of maintenance, has guaranteed blast furnace production's normal clear.
Description
Technical field
The utility model relates to a kind of not easily by the blast furnace open hole machine that the slag iron of blast furnace taphole splash burns, and belongs to technical field of metallurgical equipment.
Background technology
Iron perforater is a kind of common equipment of iron work, and its function is used to open blast furnace taphole.Iron perforater is grouped into primarily of rotating part and drilling part, and rotating part will creep into part and deliver to working position by stand, after beating tapping outlet, then is returned to stand rapidly.The reliability of iron perforater is directly connected to the production efficiency of blast furnace ironmaking.
In iron perforater operational process, usually splash slag iron after blast furnace taphole opening, especially when unstable for the stemming quality of shutoff iron notch, more easily causes the splash of slag iron, makes the drilling rod square toes of iron perforater and hit axle scaling loss or burn.Because existing iron perforater does not have effective anti-splash device, when there is slag iron splash, want to protect the strike axle of iron perforater, just must return and creep into part, so both incur loss through delay opening opportunity, affect smooth operation of furnace again.If the splash of iron mouth is out of control, in order to prevent splash from producing volume of smoke contaminate environment, creeping into part can not return immediately, adds and hits axle by the probability burnt.In addition, if after opening blast furnace taphole, iron perforater breaks down and can not return, or turns round comparatively slowly because rotating part is short of power, then certainly will burn out strike axle.Iron perforater hits frequent breakage and the repairing of axle, not only needs the human and material resources of at substantial, sometimes also can occasion a delay and tap a blast furnace, and affects the direct motion of blast furnace and stablizes, even making blast furnace be forced to checking or damping down, cause unnecessary financial loss to enterprise.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of iron perforater of high reliability, to reduce the probability that iron perforater strike axle burns, ensures normally carrying out of blast fumance.
Problem described in the utility model realizes with following technical proposals:
A kind of iron perforater of high reliability, formation comprises iron perforater body and anti-splash device, described anti-splash device comprises protective shield and hangs crossbeam, described suspension crossbeam is fixed on the top of the drilling rod of iron perforater body, described protective shield hanging is in the bottom hanging crossbeam, the drilling rod of iron perforater body passes from the centre hole of protective shield, leaves anti-collision gap between protective shield and drilling rod.
The iron perforater of above-mentioned high reliability, described protective shield is circular, is put together by two pieces of symmetrical semicircle ring flat-plates, and the upper end of every block half ring flat-plate is hinged with suspension crossbeam by the jointed shaft parallel with drilling rod.
The iron perforater of above-mentioned high reliability, described protective shield is provided with cast protective layer towards the side of blast furnace taphole.
The utility model utilizes protective shield to stop the slag iron of splash after blast furnace open hole, prevents high temperature sludge iron from burning strike axle, substantially prolongs the work-ing life of hitting axle, reduces the maintenance cost of iron perforater, ensure that normally carrying out of blast fumance.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
In figure, mark is as follows: 1, protective shield, and 2, drilling rod, 3, hang crossbeam, 4, strike axle, 5, jointed shaft.
Embodiment
The utility model has set up the anti-splash device for the protection of hitting axle on the basis of original iron perforater, causes iron perforater to hit axle damage to avoid the splash of iron mouth or iron perforater fault.
Referring to Fig. 1 and Fig. 2, the utility model comprises iron perforater body (only depict the drilling rod 2 of iron perforater body in figure and hit axle 4) and anti-splash device, and wherein, anti-splash device mainly comprises protective shield 1, hangs crossbeam 3 and jointed shaft 5.Hang the top that crossbeam 3 is fixed on the drilling rod 2 of iron perforater body, protective shield 1 entirety is circular, is put together by two pieces of symmetrical semicircle ring flat-plates, and two pieces of semicircle ring flat-plates are hinged with suspension crossbeam 3 by jointed shaft 5.
Protective shield 1 is positioned at the 500mm place, strike axle 4 front of iron perforater, neither affects the dismounting of drilling rod 2, can hit axle 4 by available protecting again, substantially prolongs the work-ing life of hitting axle 4.
Opened by the semicircle ring flat-plate of two similar hinges when installing drilling rod 2, load onto latter two semicircle ring flat-plate of drilling rod 2 by drilling rod 2 " vising ", protective shield does not affect drilling rod 2 and moves and rotate.If iron mouth generation splash in opening process, protective shield can available protecting strike axle 4 thereafter, prevents it from being burnt out by slag iron; Can not return if iron perforater breaks down, protective shield can get a small amount of valuable rescue time.
Anti-splash device makes simple and easy, install and change conveniently, without Special use restriction and requirement, one deck cast protective layer can be added towards the side of blast furnace taphole if desired at protective shield, so, both ensure that the toughness of protective shield, in turn enhance its wearing quality, if wearing and tearing appear in mould material, can fill up with stemming and continue to use.Anti-splash device is applicable to the iron perforater of general medium and small blast furnace, can effectively avoid hitting axle scaling loss or burning, and extending the work-ing life of hitting axle, is that blast furnace stable smooth operation creates conditions from periphery.
After certain blast furnace installs anti-splash device additional, at least 10 can be saved every year and hit axle, save consumptive material expense more than 20,000 yuan.
