Put.
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 smooth, it is necessary to periodically carry out large repairs, perforate again.Most Normal practice is by all of this region of tapping hole
Resistance to material is all removed and built by laying bricks or stones again（One more than 4000 cubes of the resistance to material gross weight in blast furnace iron notch position is more than 100 tons）, build
Pre-buried tapping hole when building.Cost that such a method needs is higher, long construction period.Conventional water drilling machine is employed to be drilled
Construction method, there is problems with：
1st, because carbon brick can not intake, so can not add water during drilling machine construction to carry out radiating treatment, water drilling rig steel alloy bores
Head runs at high speed, generates heat larger, and abrasion deformation amount is larger, causes to use；The consumption of drill bit is very big, and cost is very high；
2nd, water drilling drill bit front portion can not cut off cylindrical carbon brick body after having cut carbon brick, cause carbon brick body to be inconvenient to take 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, need to use extension bar using water drilling drill hole of drilling machine；One
As water drilling rig extension bar it is thinner, rigidity is inadequate, and hole linearity can not ensure during drilling；
4th, water drilling rig is run at high speed and is not added with water, produces substantial amounts of dust, and very big injury is brought to construction worker.
The content of the invention
It is an object of the invention to overcome drawbacks described above, there is provided a kind of high and safe and harmless blast furnace casting of operating efficiency
The restorative procedure and its supporting drilling equipment of mouth.
In order to achieve the above object, the present invention is realized in：

Push oil cylinder is horizontally set in frame and pipe bending cylinder is connected with sliding platform and promotes sliding platform on line slideway
Slide；Motor base is arranged on sliding platform, and drill bit drive motor is arranged on sliding platform；Bearing block is arranged on sliding platform
On, the shaft of connecting rod is located in bearing block and one end of connecting rod is connected with drill bit drive motor by the connecting-rod bearing, even
The other end of bar is connected with drill bit.
The described drilling equipment for blast furnace iron notch reparation, the connecting-rod bearing has two kinds, is conical bearing and ball respectively
Bearing.
The described drilling equipment for blast furnace iron notch reparation, drill bit drive motor are hydraulic motors or with deceleration
The motor of machine.
The described 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
Step 1, frame is fixed and drill bit is marched to close to resistance to material by drill bit by drill bit drive motor,
Step 2, the resistance to material of drill bit drive motor bit cutting is started, pass through pipe bending cylinder in the process and compress brill
Head, keep preload pressure；
Step 3, stretch out after stroke is covered and retract in pipe bending cylinder, increase transition connecting rod is repeated again with lengthening the length of connecting rod
Drilling action is above compressed, untill resistance to material drills.
The cutting element of this drilling equipment is drill bit, highly wear-resisting alloy steel cutting tool is welded with drill bit, cutter is with boring
Fixation is welded to connect using brazing between head body；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.
Brief description of the drawings
Fig. 1 is the side view of the present apparatus.
Embodiment
The present invention is further illustrated 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,
