Abstract
The utility model relates to a continuous casting middle ladle metering mouth rotary changing device, wherein a seat board is arranged on the bottom surface of a continuous casting middle ladle; three pairs of pressing plate locating convex blocks are uniformly distributed around central holes on the seat board; the lateral surfaces of pressing plates are provided with a horizontal shaft hole; each of the pressing plates is movably arranged between each pair of locating convex blocks through a pin shaft; the inner end of each of the pressing plates is provided with a convex stage, and the outer end part of each of the pressing plates is provided with a groove which is matched with a groove of the seat board and is used for installing a groove of a spring; a rotary bracket of a lower metering mouth is in the shape of a cylinder, the inner wall of the upper part of the rotary bracket is provided with an inner flange for supporting the lower metering mouth, and the upper opening part of the rotary bracket is provided with an outer flange which can be overlapped on the convex stage of each of the pressing plates; the outer circumferential wall of the rotary bracket is provided with a rotary handle. The utility model has the advantages of simple structure, complicated drive mechanism with high cost saving, and convenient, stable and reliable operation. By means of one-time lower metering mouth installation, the utility model can carry out a plurality of times of replacing operation. In the event of the failure of the continuous casting middle ladle, the utility model can make the lower metering mouth and an upper water inlet stagger to seal and block the upper water inlet and avoid accidents by rotating the rotary bracket.
Description
Technical field
The utility model belongs to the metal casting technical field, particularly relates to a kind of mouth of a river, location replacing apparatus of continuous casting tundish.
Background technology
In continuous casting tundish equipment, generally be significantly less than the service life of tundish liner the service life of its metering nozzle, can be synchronously whole in order to make the tundish service life of equipment, and in use, metering nozzle needs repeatedly to change.The quick replacement device of metering nozzle all is direct-push basically at present, promptly be connected with the guide rail plate in the tundish bottom, on the guide rail plate, be equipped with and be fixed on the matched following metering nozzle of filling pipe end of tundish bottom, also putting on the guide rail plate simultaneously has standby metering nozzle down, directly promotes standby metering nozzle down by air cylinder driven mechanism and replaces following metering nozzle in the use.The shortcoming that this direct-push quick replacement device exists is that cylinder directly promotes the mouth of a river and has certain impulsive force, damages nozzle body easily; Structure is complicated; Operation is trouble.
Summary of the invention
The technical problem that the utility model quasi-solution is determined is: for the continuous casting tundish provides a kind of structure simpler, easy to operate, the safe and reliable quick displacement apparatus of following metering nozzle.
Technical solution of the present utility model is: it comprises seat board, pressing plate, its seat board is installed on the bottom surface of continuous casting tundish, be evenly equipped with three pairs of pressing plate locating convex blocks around the seat board centre bore on the seat board, the side of pressing plate is provided with a horizontal shaft hole, by bearing pin each pressing plate is movably installed between every pair of locating convex block, the inner of pressing plate is provided with protruding rank, the outer end offers to match with the seat board groove and is used for the groove of mounting spring, following metering nozzle rotary bracket is cylindrical, its upper inside wall is provided with the supporting inward flange of metering nozzle down, upper oral part is provided with the outward flange that can be overlapped on the protruding rank of pressing plate, and the carriage periphery wall is provided with turning handle.
Can uniform installation on carriage a plurality of metering nozzles down also can offer a plurality of metering holes on a following metering nozzle body, and the axial line of each metering hole are equidistant with the axial line of following metering nozzle body.
The beneficial effects of the utility model are: simple in structure, save cost high complex drive mechanism again; Easy to operate, steady, reliable, metering nozzle under the once mounting can carry out repeatedly replacement operator; When the continuous casting tundish broke down, also rotatable carriage misplaced metering nozzle and filling pipe end and blocks filling pipe end, takes place to avoid accident.
Description of drawings
Fig. 1 is the utility model installment state general structure schematic diagram.
Fig. 2 is that Figure 1A is to view.
The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
Seat board 7 is a circular steel plate, the center offers the hole of installing bottom, the mouth of a river, on the one side of seat board 7, be evenly equipped with three pairs of locating convex blocks 3 around the center hole, offer the horizontal pin axis hole on each projection 3, the central axis of pin shaft hole and seat board RADIAL are perpendicular, at the seat board periphery, every pair of projection 3 offers groove 11 relatively, whole seat board 7 is screwed on the bottom surface of continuous casting tundish 8 by the screw slotted eye 17 of seat board periphery; The side of pressing plate 5 also is provided with horizontal shaft hole, by bearing pin 10 pressing plate is connected and installed between every pair of projection 3, the groove 12 that the leading section of pressing plate 5 is provided with protruding rank 14, the outer end offers matches and be used for mounting spring 6 with seat board groove 11 also is provided with the set screw 4 of regulating spring 6 on the pressing plate; The spring 6 of present embodiment adopts the high-temperature gas spring; The rotary bracket 1 of following metering nozzle is a cylinder, and its upper inside wall is provided with the supporting inward flange of metering nozzle 15 down, and upper oral part is provided with the outward flange 13 that can be overlapped on the protruding rank 14 of pressing plate, and the carriage periphery wall is provided with turning handle 2.The following metering nozzle 15 of present embodiment be evenly equipped with three metering holes 16 on its nozzle body, and the axial line of the axial line of each metering hole 16 and nozzle body is equidistant.Make down one of them metering hole 16 butt joint filling pipe end 9 of metering nozzle during use, when this metering hole uses to the hole enlargement limit, only need rotating bracket handle 2, water hole 9 gets final product to make another metering hole 16 aim at upward.By that analogy, replacement operator is very easy.
