Description
Technical field
The invention belongs to the technical field of ladle upper nozzle detaching equipment, specially a kind of front inserting filling pipe end disassembly dress
It sets.
Background technique
Replacing filling pipe end is the maximum work of steel mill ladle-pot hot-repair workshop section labor intensity, the especially work of summer worker
Environment is more severe, some steel mills take the filling pipe end of tooling disassembly at present, but using effect is unsatisfactory.
Currently, the disassembly of filling pipe end is mainly smashed service life overdue filling pipe end with pneumatic pick, cleaning is then further taken out
This traditional mode, it is longer with the time, it is larger to brick cup damage, the online service life of ladle is influenced, worker needs low coverage
From operation, severe operational environment, labor intensity of workers is big, also to consider that filling pipe end is torn open in hot repair staffing and turnover ladle quantity
Unload the longer and time of taking time it is uncertain the problems such as influence；Also there are individual steel mills using simply from ladle mouth insertion steel disk drawing
Then head dismantles filling pipe end from mechanism side with the mode that oil cylinder pulls out, but the uncertain of filling pipe end remaining lengths influences to tear open
The success rate unloaded, employment is more, and part operation part is due to the too big flexible deformation of across high-temperature region distance.
Application No. is 2015101237201 patent application, a kind of entitled ladle upper nozzle quickly online provision for disengagement,
Technical background of the provision for disengagement designed by it is more special, using with limitation, can not large-scale application, it is domestic at present most
Substantially traditional filling pipe end disassembly mode is that will smash taking-ups to the filling pipe end in service life with pneumatic pick, and cleaning simultaneously more renews.
The problems of this device:
1, since pull head is needed with air-cooled push rod from being sent into filling pipe end to be removed before ladle, across from ladle mouth to packet
The high-temperature area at bottom is used for a long time, air-cooled push rod meeting bending deformation, increases bar diameter raising rigidity manpower and is difficult to operate again.
2, the push of air-cooled push rod needs very large space to operate in ladle front.
3, need to be more with personnel, the push of air-cooled push rod, pull head and pull rod fasten and the behaviour of Hydraulically Operated Equipment before ladle
It has been both needed to personnel depaly.
4, pull head and pull rod buckling parts bit manipulation require coaxiality error too big, for button herein in practical operation
It closes, needs to adjust the position of each pull head and pull rod, waste time also more.
5, filling pipe end was used to after the service life, and the length is uncertain values, although this device pull head component can pre-adjust,
But measurement and alignment error are very big in actual use, and it is lower that filling pipe end removes success rate.
Application No. is 2015103384239 patent application, a kind of entitled disassembly work of steel casting upper nozzle brick
Tool, extracting tool disclosed in the tool contain 2015101237201 existing for all problems, and pull head is unable to adjust, in dismounting
Mouth of a river success rate is lower.
Summary of the invention
The present invention is more for above-mentioned disassembly employment, operation difficulty is big, wants to extracting tool and personnel and operating space
The problems such as high is asked, a kind of front inserting filling pipe end provision for disengagement is provided, the solution disassembly filling pipe end time is too long, employment is too many asks
Topic, provision for disengagement of the invention, key technology is can be inserted into from filling pipe end bottom (mechanism side), then device pull head turnover panel
It opens and holds filling pipe end upper end, then rear locking cylinder distance, effective impulse stroke of oil cylinder is improved as far as possible, by another worker
Operation hydraulic station drive cylinder pulls down filling pipe end.
Technical scheme is as follows:
A kind of front inserting filling pipe end provision for disengagement, which is characterized in that including double outlet-rod hydraulic cylinder bodies, piston rod I, piston rod
II and pull rod, double outlet-rod hydraulic cylinder bodies are hollow structure, in the fixed position-arresting disk in I end of piston rod；Pull rod through it is double go out
Bar hydraulic cylinder and position-arresting disk, piston rod II are fixedly connected by piston rod protection head with pull rod；The one of the nearly position-arresting disk of pull rod
The end at end is drawhead, and drawhead is equipped with hollow groove, and hollow groove is interior to be fixed with turnover panel by shaft, in the bar of the pull rod other end
Body is equipped with limit hole, is combined with spacer pin with limit hole.
The features of the present invention is also:
I end of piston rod passes through the fixed position-arresting disk of hexagon socket cap head screw.
It further include miniature movable type hydraulic station, the fitting body of double outlet-rod hydraulic cylinder bodies is connect by pipeline with hydraulic station.
The drawhead is cylindrical rod head.
The filling pipe end provision for disengagement of this front inserting, when in use, operator station is in ladle bottom mechanism side, by drawhead from upper
It is extend into ladle in mouth of a river, rotating rod, turnover panel is rotated along shaft, and operator pulls out pull rod, and turnover panel withstands on Shang Shui
Edge on mouth pushes position-arresting disk to lean against the slide gate mechanism pedestal installed on packet bottom, then close to piston rod on rear side of hydraulic cylinder
Spacer pin is plugged in the position of protection head on pull rod, operates hydraulic station, and piston rod pushes spacer pin that pull rod is forced away from packet bottom
The turnover panel in direction, rod head moves out, and filling pipe end is pulled out.
The beneficial effects of the present invention are:
The beneficial effect slitting of the present apparatus is as follows:
1, by being inserted into behind ladle, without above-mentioned pull head push rod, operation content before no ladle dismantles work during filling pipe end
People is far from high-temperature region.
2, no matter filling pipe end uses any degree, and it is that pull head turnover panel tenses locking cylinder after filling pipe end, operation that we, which operate,
Success rate is high.
3, personnel are few in operating process, and only a people is inserted into pull rod, hold filling pipe end finger lock oil cylinder, then operate hydraulic cylinder
Filling pipe end is pulled out.Time is short, and skilled operation is less than 1 minute.
In short, the apparatus structure is simple, it is not take up site space, only by the operator that stands in ladle bottom from upper when operation
Mouth of a river is inserted into drawhead into ladle, without other personnel from ladle operation made above, conveniently, efficiently, it is red to meet steel mill
The allegro requirement of packet tapping reduces hot repair worker and is equipped with quantity, ton steel cost is effectively reduced, improves worker laboring environment, subtract
Light labor intensity of workers.And such pull-out mode protects brick cup inner surface and end to greatest extent, extend brick cup and
The service life of ladle.
Front inserting filling pipe end provision for disengagement of the invention is suitable for 80 tons or more ladles, and filling pipe end is big and is difficult to pneumatic pick
The steel mill of disassembly；It is smaller suitable for hot repair operation field, the steel mill of no spiral arm lifting and hydraulic interface.
