Description
Technical field
The utility model relates to the desulfurization treatment unit field of the pig iron, is specially a kind of rapid tool change of molten iron desulphurization stirring oar.
Background technology
Iron ladle stirring desulphurization technique is that the cross desulfurization stirring rake with the castable of anti-the material is inserted Stirring in the iron ladle after baking, make molten iron produce whirlpool, then in molten iron whirlpool district, drop into sweetening agent, make the element sulphur in sweetening agent and the molten iron in the whirlpool that constantly generates along with stirring, desulphurization reaction occur.The desulfurization stirring rake is maximum expendable part in stirring desulphurization equipment, owing to being subject to the erosion of high temperature liquid iron and washing away, after the desulfurization stirring rake used for some time, outside anti-material damaged, and replacing online need stop production.Renewal process is: at first old desulfurization stirring rake is pulled down and transported working position, and then new desulfurization stirring rake is transported to working position installs.The whole oar process of changing, transporting of desulfurization stirring rake, be transported into is that centering is all realized by a replacing chassis, the desulfurization stirring rake is changed chassis and is seen Fig. 1, change chassis 1 along the track traveling, in order to desulfurization stirring rake 2 is transported into or transports, the lodging bench 3 that a desulfurization stirring rake is arranged at replacing chassis 1 simultaneously, lodging bench 3 is a movable platform, about can realizing by hydraulic drive, about, the actions such as front and back and rotation, these actions are used for realization to the accurate location of desulfurization stirring rake, make one by one centering of bolt hole on the desulfurization stirring rake 2 body flanges (being the lower flange sheet) and the bolt hole on whipping appts 4 joint flanges (being the upper flange sheet), penetrating one by one bolt hole with bolt again connects, can real upper flange sheet and lower flange sheet be fixed, thereby finish desulfurization stirring rake 2 is fixed on the whipping appts 4.This operational method, a large amount of time loss are in the centering operation, and accurate location difficulty, and replacing once more than the 80min consuming time, directly causes the treatment time of Beater operator bit-loss two stoves, and is larger to Influence of production.
The utility model content
In order to overcome the defective of prior art, a kind of simple in structure, easy to use, high efficiency, safe and reliable more changing device are provided, the utility model discloses a kind of rapid tool change of molten iron desulphurization stirring oar.
The utility model reaches goal of the invention by following technical solution:
A kind of rapid tool change of molten iron desulphurization stirring oar, comprise wireline, it is characterized in that: also comprise the collar, wireline has three at least, and the length of each root wireline and diameter are all equal respectively, and a collar is fixed at the two ends of every wireline, the collar is comprised of ring body and clevis bolt, ring body is " recessed " font, and an end of wireline is fixed on the base of ring body, and clevis bolt passes respectively two parallel opposite side of ring body.
The rapid tool change of described molten iron desulphurization stirring oar is characterized in that: the length of wireline is all at 250mm～350mm, and the diameter of wireline is all at 20mm～30mm.
When the utility model used, desulfurization stirring rake that first will be old was removed and is hung away, new desulfurization stirring rake is transported to working position and places on the lodging bench, and the body flange that the jacking lodging bench makes the desulfurization stirring rake is the joint flange of close whipping appts gradually; When the distance between body flange and the joint flange during less than the length of wireline, stop jacking, the collar at wireline two ends is enclosed within respectively on the hook in the body flange outside and on the hook in the joint flange outside, and makes wireline center on the body flange and joint flange is evenly distributed; Descend subsequently lodging bench until the desulfurization stirring rake by unsettled the slinging of wireline and and lodging bench break away from, because wireline can only produce pulling force and can not produce thrust body flange and joint flange, the desulfurization stirring rake is in plumbness with automatic rotation to wireline under action of gravitation, this moment, each bolt hole of body flange and joint flange also alignd one by one, had namely finished self-centering; Penetrate bolt hole and assembling with two long tack bolts this moment first, namely finished quick location; Jacking lodging bench again subsequently, lodging bench is with desulfurization stirring rake jack-up, until wireline all is in the relaxed state that does not stress, wireline is taken off, and connects one by one all residue bolts, finishes the installation of new desulfurization stirring rake.
The utility model is simplified apparatus effectively, shortens the activity duration: because the centering operation is finished automatically, the requirement of lodging bench reduces greatly, only keeps elevating function and gets final product, and no longer needs complicated direction to move control; Changing the oar operation only needs about 40min, has both reduced to change the oar operation quantity-produced is affected, and has also improved production efficiency.
The beneficial effects of the utility model are: simple in structure, easy to use, and high efficiency, safe and reliable.
