Description
Technical field
The utility model relates to blast furnace service technique field, particularly relates to a kind of iron making blast furnace skin drilling equipment.
Background technology
The emphasis of each blast furnace system maintenance of iron-smelter is shell of blast furnace boring and installs cooling stud project, due to blast furnace system maintenance belong to multidisciplinary, entry, multiplex (MUX) plants operation simultaneously, duration schedule requirement is extremely strict, therefore, need to set about from rig and cutter aspect, improve drilling efficiency, for the system overhaul of whole blast furnace holds arteries and veins.Because in blast furnace system maintenance process, can cooling stud be in place on schedule, and can involve the maintenance of whole blast furnace system complete normally on schedule, and can blast furnace blow on schedule resume production, and project of all holing with shell of blast furnace is closely bound up, be closely connected.
At present, usual employing outsourcing drilling machine finished product holes to shell of blast furnace, but this finished product drilling machine exists, and cost is high, efficiency is low, cannot carry out the shortcoming of changing according to operation field situation, simultaneously, owing to lacking spare part and cannot changing in time when part of appliance breaks down, and when vexed car situation encountered by drilling machine, motor very easily burns; Finished product drill bit belongs to machine welding and reconditioning, cannot repair.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of iron making blast furnace skin drilling equipment of effective raising operating efficiency.
For solving the problem, a kind of iron making blast furnace skin drilling equipment described in the utility model, is characterized in that: the sliding support that this device comprises cutter head, the reductor be connected with motor and is socketed on support bar; Described cutter head comprises hollow, the cylindrical and cutter hub of bottom lock; The end of described cutter hub is equally spaced is inlaid with 8 alloy threading tool heads, is connected bottom it with the output shaft of described reductor; The both sides of described motor and described reductor are all fixed on described support bar; Described support bar and Connection Block weld together; Described sliding support is connected with handle by advancing screw mandrel.
The lengthwise position of each cutter head in described 8 alloy threading tool heads and the center line of described cutter hub are 10 ° of angles.
Each cutter head in described 8 alloy threading tool heads is provided with 5 cutting faces.
The utility model compared with prior art has the following advantages:
1, owing to being provided with support bar and propulsion lead screw in the utility model, therefore, the difficult problem cannot constructed because of narrow space can be solved.
2, in the utility model, cutter head comprises hollow, the cylindrical and cutter hub of bottom lock, and the end of this cutter hub is equally spaced is inlaid with 8 alloy threading tool heads, therefore, be easy to timely reparation, hand grinding, not only promote cutter sharpness, and reduce cost, improve operating efficiency.
3, after adopting the utility model, remarkable in economical benefits.
Shell of blast furnace Special drill machine procurement price is 15000 yuan/platform (not containing drill bit) in the market, finished product drill bit procurement price is 300 yuan/, calculate to need drilling machine 10 in construction work, every platform is equipped with 6 kinds of specifications (length is 80mm, 120mm, 150mm, 200mm, 250mm, 300mm) drill bit, and this outsourcing drill bit belongs to unrepairable, buying expenses adds up to 16.8 ten thousand yuan (not containing the renewal cost of cutter in work progress).And in the utility model except motor, reductor buying, all the other equal parts all can be processed voluntarily, purchase cost about 3000 yuan/platform, processing cost 1000 yuan/platform, add up to expense 4000 yuan/platform, amount to 40,000 yuan.12.8 ten thousand yuan can be reduced costs.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1-cutter head, 2-motor, 3-reductor, 4-support bar, 5-sliding support, 6-propelling screw mandrel 7-handle, 8-Connection Block, 9-alloy threading tool head 10-stove epidermis face.
Detailed description of the invention
As shown in Figure 1, a kind of iron making blast furnace skin drilling equipment, the sliding support 5 that this device comprises cutter head 1, the reductor 3 be connected with motor 2 and is socketed on support bar 4.Cutter head 1 comprises hollow, the cylindrical and cutter hub of bottom lock; The end of cutter hub is equally spaced is inlaid with 8 alloy threading tool heads 9, is connected bottom it with the output shaft of reductor 3; Motor 2 is all fixed on support bar 4 with the both sides of reductor 3; Support bar 4 and Connection Block 8 weld together; Sliding support 5 is connected with handle 7 by advancing screw mandrel 6.
Wherein: the lengthwise position of each cutter head in 8 alloy threading tool heads 9 and the center line of cutter hub are 10 ° of angles.
Each cutter head in 8 alloy threading tool heads 9 is provided with 5 cutting faces.
During use, by the periphery situation of Connection Block 8 according to stove hole skin position, gas cutting welds and stove epidermis face 10 after becoming suitable dimension, and keeps relative verticality with the utility model; In operation process, turning handle 7 promotes to advance screw mandrel 6, is with dynamic cutter head 1 feed by the sliding support 5 be connected on motor 2 and reductor 3.If there is vexed car situation in boring procedure, disable motor 2, taps out part with hammer by the utility model immediately, can continue operation; If cutter head 1 serious wear or fracture in boring procedure, carry out changing.
