Abstract
A tundish hydraulic quick-change water port device belongs to the technical field of metallurgical steelmaking technology. The existing tundish hydraulic quick-change water port device has a bulky and cumbersome fuel cylinder, is complicated in operation, is inconvenient for platen gap adjustment and easily leads to leakage. The technical proposal of the utility model is that a base (5) is provided with a pneumatic spring (2), a one-piece water port (7) and a fuel cylinder bracing frame (9), the platens (1) which are screwed with four fastening adjustment bolts (3) are inserted on the base (5) through an axis pin (4), a hydraulic outfall (8) is embedded between the two platens (1), the fuel cylinder holding frame (9) is provided with a fuel cylinder (10), a connecting plate (6) is fixed on the base (5) through fixed screws (11), a fuel cylinder (10) is provided with a crown bar (12), four pneumatic springs (2) are arranged between the platen (1) and the base (5). The utility model has the advantage that the fuel cylinder is compact and light, the operation is simple, the platen gap adjustment is convenient, and the sealing performance is good so that the molten steel does not leak.
Description
Technical field: the utility model relates to metallurgical steelmaking equipment technical field, is a kind of tundish hydraulic pressure fast sprue-replacing device more specifically.
Background technology: the big heaviness of existing tundish hydraulic pressure fast sprue-replacing device oil cylinder volume, complicated operation, platen gap is adjusted inconvenient, the big bleed-out water in gap, the mouth of a river can not finely be moved under the little hydraulic pressure in gap.
Summary of the invention: for overcoming above-mentioned shortcoming, the purpose of this utility model is a kind of tundish hydraulic pressure fast sprue-replacing device of design.Its technical scheme is: pneumatic spring 2, the disjunctor mouth of a river 7 are housed on the base plate 5 and are plugged with oil cylinder bracing frame 9, being screwed with four pressing plates 1 of adjusting bolt 3 is plugged on the base plate 5 by pivot pin 4, the mouth of a river 8 is embedded between two pressing plates 1 under the hydraulic pressure, oil cylinder bracing frame 9 is provided with oil cylinder 10, connecting plate 6 is fixed on the base plate 5 by fixed screw 11, oil cylinder 10 is provided with push rod 12, four pneumatic springs 2 is housed between pressing plate 1 and base plate 5.The advantage of this utility model is: the reasonable in design practicality, novelty is skillfully constructed, this tundish hydraulic pressure fast sprue-replacing device oil cylinder volume is little lightly simple to operate, platen gap good seal easy to adjust is bleed-out water not, mouth of a river good seal conveniently moving has improved productivity ratio under the hydraulic pressure, and long service life has reduced production cost; Oil cylinder frame and base plate are that one makes oil cylinder fixing more firm, and location, the following mouth of a river accurately; Pressing plate adopts lever principle, and the centre penetrates bearing pin and makes fulcrum, and the outside is used four pneumatic springs and finely tune effective cooperation and the pressure of having guaranteed time mouth of a river and gap, the disjunctor mouth of a river with bolt even, has avoided bleed-out water and folder molten steel accident; During the design of pressing plate groove has been guaranteed to use down the mouth of a river and the disjunctor mouth of a river effective cooperate and make stand-by and the following mouth of a river that back off does not stress and alleviated pneumatic spring firmly, guaranteed that time mouth of a river cooperates with the effective of the disjunctor mouth of a river, avoided bleed-out water and pressed from both sides the molten steel accident.
Description of drawings: Fig. 1 front view, the view of Fig. 2 for making progress at Figure 1A, Fig. 3 is at Figure 1B-B place cutaway view.In the accompanying drawing: 1, pressing plate, 2, pneumatic spring, 3, adjust bolt, 4, pivot pin, 5, base plate, 6, connecting plate, 7, the disjunctor mouth of a river, 8, the mouth of a river under the hydraulic pressure, 9, the oil cylinder bracing frame, 10, oil cylinder, 11, fixed screw, 12, push rod.
The specific embodiment: pneumatic spring 2, the disjunctor mouth of a river 7 are housed on the base plate 5 and are plugged with oil cylinder bracing frame 9, being screwed with four pressing plates 1 of adjusting bolt 3 is plugged on the base plate 5 by pivot pin 4, the mouth of a river 8 is embedded between two pressing plates 1 under the hydraulic pressure, oil cylinder bracing frame 9 is provided with oil cylinder 10, connecting plate 6 is fixed on the base plate 5 by fixed screw 11, oil cylinder 10 is provided with push rod 12, four pneumatic springs 2 is housed between pressing plate 1 and base plate 5.At first on the connecting plate 6 weldering tundish, be screwed on the connecting plate 6 with key screw base plate 5 then, the disjunctor mouth of a river 7 is inserted in the base plate 5, dress pneumatic spring 2 between pressing plate 1 and base plate 5, insert pivot pin 4 then, again adjustment bolt 3 being passed pressing plate 1 is screwed on the base plate 5, the mouth of a river 8 under 2 hydraulic pressure is pushed in the groove between the pressing plate 1, oil cylinder 10 is screwed on the oil cylinder bracing frame 9, the push rod 12 of oil cylinder 10 is aimed at the mouth of a river 8 under the hydraulic pressure, when dropping down molten steel, start oil cylinder 10 usefulness push rods 12 and promote under the hydraulic pressure mouth of a river 8 and the disjunctor mouth of a river 7 water holes outflow molten steel that communicates of tapping; Because heating to expand, ladle environment temperature rising pneumatic spring 2 make pressing plate 1 gap between the mouth of a river 8 and the disjunctor mouth of a river 7 under pivot pin 4 turns an angle clamping platen 1, hydraulic pressure make it better bleed-out water not of sealing.
