In tundish stated above position.Ladle is placed on panoramic table by the driving received with molten steel across side, passes through panoramic table
Turning round, which makes ladle be parked on tundish, supplies its molten steel.The empty Bao Ze poured transports molten steel back by panoramic table revolution and received again
Across.
Replacing for pivoting support, be usually fragmentary dismounting method, i.e. each fragmentary component to ladle turret and its attached
Category equipment is progressively removed, installed, and this method wastes time and energy, when needing even tens of days a couple of days according to specification of equipment size is estimated
Between.
The content of the invention
Its purpose of the invention is that a kind of integrally lifted according to crane gear of offer changes conticaster ladle pivoting support
Method, the replacing options for solving traditional pivoting support exist and waste time and energy, and need a couple of days according to specification of equipment size is estimated
The problem of even tens of days time.
Adopt the technical scheme that to achieve the above object, a kind of integrally lifted according to crane gear changes conticaster steel
The method of bag pivoting support, including step：
（1）Ladle under traveling crane is commanded first, is removed bale panoramic tables periphery wall brick, site clearing greasy dirt, is conveniently replaceable operation；
（2）Forks arm is risen into extreme higher position, steel plate positioning is filled between forks arm and principal arm gap, then on cement beam
Side's installation jacking cylinder and column, adjustment make column keep plumbness, and column upper end is determined with forks arm decorated fire solid welding；
（3）Remove locking device, hydraulic slip ring, electric slip ring and the inside and outside circle connecting bolt of pivoting support on pivoting support；
（4）Control jacking cylinder jacks examination top simultaneously, after confirming that bale panoramic tables leave base, increases the operation of jacking amount, until
After bale panoramic tables ascending amount reach a certain height, pitched with scissors and reinforce column, then protection column is installed；
（5）Bale panoramic tables lower end is fixed on chain block to lift pivoting support, the insertion sliding steel pipe on base, then
Pivoting support inner ring bolt is up lifted while inserts ready thin plate, allows inner ring bolt to fall on thin plate, then will revolution
Supporting is placed on sliding steel pipe；
（6）A platform is concordantly built in base side, pivoting support level is pulled out on platform with chain block, completed back
Turn the dismounting of supporting, then new pivoting support is installed.
Beneficial effect
The present invention has advantages below compared with prior art.
The present invention proposes a kind of method for integrally being lifted according to crane gear and changing conticaster ladle pivoting support, this method
It is simple with technique, it is easy to operate, securely and reliably, it is time saving and energy saving the advantages of.
