Description
Technical field
The present invention relates to the desulfurization agitator head safe elevating control dress that in desulfurizer, desulfurization agitator head lifts safely can be made
Put.
Background technology
In steel mill, desulfurizer is used to molten iron in ladle be carried out with the equipment of desulfurization, in desulfurizer during work
Desulfurization agitator head extend in ladle molten iron is carried out with desulfurization after declining, after the completion of desulfurization work desulfurization agitator head rise again extensive
Restore position.The structure of the apparatus for controlling of lifting of control desulfurization agitator head lifting is: is provided with reel in frame, reel passes through steel
Cord drives desulfurization agitator head oscilaltion, and reel is driven by the decelerator being installed in frame, in the output shaft two of decelerator
Side is additionally provided with band-type brake, and after desulfurization agitator head stop motion, band-type brake can embrace reducer output shaft, prevents desulfurization agitator head from falling
Fall, motor mutually can be driven with decelerator by clutch respectively with pneumatic means, is provided with Motor drive shelves gentle in clutch
Dynamic drive, can make clutch change between two gears by stirring clutch and dialling handle, when clutch is in Motor drive shelves
When, by Motor drive, when clutch is in pneumatic actuation shelves, decelerator is driven decelerator by pneumatic means, in frame also
Be provided with can controlled motor, pneumatic means and band-type brake work controller, be provided with permutator, pneumatic in the controller
Rise button, electronic rising button, electronic decline button；Wherein permutator has normal condition and two shelves of accident condition
Position, when permutator is in normal condition gear, controller actuating motor driver carrys out controlled motor, at permutator
When accident condition gear, controller executes pneumatic actuation program to control pneumatic means.
In the case of normal power-up, the lifting of desulfurization agitator head is by Motor drive.But, when desulfurization agitator head is entering to molten iron
During row desulfurization, when such as occurring power-off, frequency converter failure etc. to make the accident that motor cannot work, considering for safety needs handle
Desulfurization agitator head is lifted and removes to keep in repair at fault, at this moment because motor cannot work, so desulfurization agitator head
Lifting need to by Motor drive be converted to pneumatic means drive；The above-mentioned operation step being converted to pneumatic means driving by Motor drive
Suddenly as follows: to make it be converted to accident condition gear by original normal condition gear firstly the need of switch transition switch, then dial
Handle dialled by dynamic clutch makes clutch be converted to pneumatic actuation shelves by original Motor drive shelves, and finally pressing pneumatic rising button makes
Controller executes pneumatic actuation program, and controller can make the band-type brake of reducer output shaft both sides open simultaneously, thus can be by
Pneumatic means drives desulfurization agitator head to rise.
During desulfurization agitator head is converted to pneumatic means driving by Motor drive, permutator is being cut by operator
After shifting to accident condition gear, often forget that stirring clutch dials handle, such clutch cannot be from original Motor drive
Shelves are converted to pneumatic actuation shelves, and in this case after operator press pneumatic rising button, controller still can make deceleration
The band-type brake of device output shaft both sides is opened, but because pneumatic means is not driven to decelerator, may result in desulfurization agitator head
Decline in the presence of deadweight, because the weight of desulfurization agitator head is larger, so huge impact will be produced during declining,
Cause great potential safety hazard.

Device 2 drives desulfurization agitator head to rise.
In the present embodiment, each binding post is band cartridge fuse binding post, permissible using band cartridge fuse binding post
Play the effect of overload protection.Alarm 8 is band flashing lamp alarm, and band flashing lamp alarm warning function is higher, more can draw
Play the attention of operator.Travel switch 4 is Direct Action Type travel switch, simple and reliable for structure, the price of Direct Action Type travel switch
Cheaply.Display lamp 81 is 24v display lamp, and 24v display lamp best suits the voltage of controller 9 circuit.Also set in the lower section of alarm 8
It is equipped with and can teaching process personnel need when alarm 8 is reported to the police clutch 3 to be switched to the mark of pneumatic actuation shelves, in this mark
Content can be " clutch is please switched to pneumatic actuation shelves by accident condition "；It is provided with and can accuse in the lower section of display lamp 81
Know that operator's clutch 3 when display lamp 81 is shinny has been located in the mark of pneumatic actuation shelves, the content in this mark can be
" when display lamp is shinny, clutch has been located in pneumatic actuation shelves ", mark being provided below in alarm 8 and display lamp 81 can refer to
Lead operator and carry out next step operation, improve work efficiency and processing safety.
The operation principle of the safe apparatus for controlling of lifting of the desulfurization agitator head described in the present embodiment is: as shown in Figure 1 and Figure 2, when
When permutator 82 is located at normal condition gear, controller 9 actuating motor driver carrys out controlled motor, now can be using electricity
Dynamic rising button 841 and electronic decline button 84 lifting to control desulfurization agitator head；When permutator 82 is located at accident condition
During gear, alarm 8 can be reported to the police, and then operator are it will be noted that mark below this alarm condition and alarm 8, operation
Personnel, according still further to the prompting in mark, stir clutch and dial handle 31 so that clutch 3 is converted to by original Motor drive shelves pneumatic
Drive, now decelerator 5 do not driven by motor 1, but driven by pneumatic means 2, when clutch 3 is converted to pneumatic actuation shelves
Afterwards, display lamp 81 understands shinny, alarm 8 meeting stop alarm, finally presses pneumatic rising button 83, controller 9 can open band-type brake 6
And make pneumatic means 2 drive desulfurization agitator head to rise.Note, if operator are not converted to pneumatic driving clutch 3
Dynamic shelves, that is, clutch dial handle 31 and do not touch travel switch 4, now display lamp 81 is shinny, alarm 8 is still reported to the police, this
In the case of, after operator press pneumatic rising button 83, controller 9 will not open band-type brake 6, and at this moment desulfurization agitator head will not be because
It is not have pneumatic means 2 to drive.
The invention has the benefit that the safe apparatus for controlling of lifting of desulfurization agitator head of the present invention can stir in desulfurization
Head by Motor drive be converted to pneumatic means drive when give operator operation indicating, and when clutch do not switch to pneumatic
During drive, pressing pneumatic rising button cannot make the band-type brake of reducer output shaft both sides be opened, and such desulfurization agitator head is just
Do not fall out, substantially increase the safety of desulfurization agitator head lifting work.
