Description
Technical field
The present invention relates to maintaining blast furnace field, specifically a kind of drilling equipment for blast furnace iron notch reparation.
Background technology
The etch of long-term molten iron is passed through at its tapping hole position to the industrial blast furnace of smelter when in use, and iron mouth hole is easy
Blocking causes to tap a blast furnace not freely, needs periodically to carry out large repairs, trepanning again.Most Normal practice is by all of this region of tapping hole
Resistance to material is all removed and is built by laying bricks or stones again（One 4000 cubes or more of the resistance to material total weight in blast furnace iron notch position is more than 100 tons）, build
Pre-buried tapping hole when building.Cost that such method needs is higher, long construction period.Conventional water drilling machine is employed to drill
Construction method has problems with：
1st, since carbon brick cannot intake, so water cannot be added during drilling machine construction to carry out radiating treatment, water drilling drilling machine alloy
Steel bit runs at high speed, it is larger to generate heat, and abrasion deformation amount is larger, causes to use；The consumption of drill bit is very big, and cost is very
It is high；
2nd, water drilling drill bit forepart cannot cut off cylindrical carbon brick body after having cut carbon brick, and carbon brick body is caused to be inconvenient to take
Go out, the deeper position of depth is more not easily taken out, and causes construction period long, influences engineering project progress；
3rd, the general 2500 ~ 3000mm of the depth of tapping hole carbon brick layer is needed using water drilling drill hole of drilling machine using lengthening
Bar；General water drilling drilling machine extension bar is thinner, and rigidity is inadequate, and hole straightness can not ensure during drilling；
4th, water drilling drilling machine runs at high speed and is not added with water, generates a large amount of dust, and very big wound is brought to construction worker
Evil.
Invention content
It is an object of the invention to overcome drawbacks described above, a kind of operating efficiency height and safe and harmless blast furnace casting are provided
The restorative procedure and its mating drilling equipment of mouth.
In order to achieve the above object, the invention is realized in this way：
A kind of drilling equipment for blast furnace iron notch reparation drives including drill bit, connecting rod, the connecting-rod bearing, bearing block, drill bit
Dynamic motor, motor base, pipe bending cylinder, rack, the linear guide and mating sliding platform；Wherein, the linear guide and sliding platform are
It is horizontally set on to pipe bending cylinder in rack and pipe bending cylinder connect with sliding platform and sliding platform is pushed to be led in straight line
It is slided on rail；Motor base is arranged on sliding platform, and drill bit drive motor is arranged on sliding platform；Bearing block is arranged on slip
On platform, the shaft of connecting rod is threaded through in bearing block and one end of connecting rod connects with drill bit drive motor by the connecting-rod bearing
It connects, the other end of connecting rod is connect with drill bit.
The drilling equipment for blast furnace iron notch reparation, there are two types of the connecting-rods bearing, is conical bearing and ball respectively
Bearing.
The drilling equipment for blast furnace iron notch reparation, drill bit drive motor are hydraulic motors or with deceleration
The motor of machine.
The drilling equipment for blast furnace iron notch reparation, drill bit are push pipe formula of the end face with cutter head and tooth
Drill bit.
The application method of the drilling equipment, including
Rack is fixed and passes through drill bit drive motor drill bit is marched to drill bit close to resistance to material by step 1,
Step 2 starts the resistance to material of drill bit drive motor driving bit cutting, is compressed in the process by pipe bending cylinder
Drill bit keeps preload pressure；
Step 3 is stretched out after stroke is covered in pipe bending cylinder and is retracted, and increases transition connecting rod to lengthen the length of connecting rod, again
It repeats front and compresses drilling action, until resistance to material drills.
The cutting element of this drilling equipment is drill bit, highly wear-resisting alloy steel cutting tool is welded on drill bit, cutter is with boring
Fixation is welded to connect using brazing between head ontology；In bit alloy-steel cutter into contact with resistance to material cut.
In this way, the various inconvenience present in traditional water drilling drilling machine construction are abandoned.
Description of the drawings
Fig. 1 is the side view of the present apparatus.
Specific embodiment
It is further illustrated the present invention below by way of specific embodiment.
As shown in Figure 1, a kind of drilling equipment for blast furnace iron notch reparation, including drill bit 1, connecting rod 2, the connecting-rod bearing 3,
Bearing block 4, drill bit drive motor 5, motor base 6, pipe bending cylinder 7, rack 8, the linear guide 9 and mating sliding platform 10；Wherein,
The linear guide 9 and sliding platform 10 or even pipe bending cylinder 7 are horizontally set in rack 8 and pipe bending cylinder 7 and sliding platform
10 connect and sliding platform 10 are pushed to be slided in the linear guide 9；Motor base 6 is arranged on sliding platform 10, drill bit driving horse
It is arranged on sliding platform 10 up to 5；Bearing block 4 is arranged on sliding platform 10, and the shaft of connecting rod 2 is worn by the connecting-rod bearing 3
