Definitions

  • the invention relates to a manipulator for guiding a pouring tube under a metal-containing container, with a support frame which can preferably be displaced on rails and at least one connecting element which runs in the latter in one or more guideways and holds the pouring tube and by means of which the pouring tube is formed in a web shape from an approximately horizontal into an vertical position is movable under the container, wherein at least one connecting element can be moved along a guide path by a displacement element provided in the support frame and the pouring tube is detachably held on the connecting element.
  • the present invention relates to an increasingly common requirement in steel mills, according to which a change of the pouring tube during the continuous casting must take place without interruption.
  • the small distance between the container known as a distributor and the continuous casting mold requires an exact insertion of the pouring tube into the mold.
  • the connecting element holding the pouring tube is displaceable along a guideway.
  • a cylinder-piston unit which interacts with a chain drive and a telescopic arm carrying the connecting element.
  • a second chain drive is provided for simultaneously pivoting the pouring tube about the axis of rotation of the connecting element. This is kinematically connected to the first chain drive via the telescopic arm.
  • guides are provided on both sides for pouring out the container provided in which guide pins of a pouring tube holder slide.
  • the guideways are designed in such a way that the pouring tube is guided in the said manner from a horizontal position into a vertical position immersed in the mold melt and under the spout.
  • a disadvantage of this device is sometimes the manual introduction of the pouring tube. On the one hand, the space is usually very narrow and, on the other hand, there is also a certain danger for the man operating the pouring tube because of the heat load and because of possible unforeseen melt discharge.
  • the present invention is therefore based on the object of providing a manipulator for guiding a pouring tube under a melt containing container, with which a user-friendly, simple construction which is easily adaptable to the space conditions of the overall system and which is easily adaptable to the rough conditions of the entire plant for precisely guiding the pouring tube is achieved.
  • the object is achieved with a manipulator of the type mentioned in that the connecting element for the pouring tube has an auxiliary steering lever, one end of which is rotatably mounted in the connecting element or is fixedly connected to it and holds the pouring tube, and the other end of which is in an additional guideway is guided, this guideway to the path of the connecting element in the direction of advancing the pouring tube continuously diverges at an angle between 5 ° and 30 °, and the pouring tube is releasably held on the connecting element such that it is connected in a stationary state to the connecting element or from this can be solved.
  • the actuating device for the connecting element consists solely of the displacement member as the drive means.
  • the displacement member does not have to be mounted on two different housing parts which can be displaced relative to one another. This not only leads to a constructive simplification of the device, but also offers the advantage of a precise fixing of the two guide tracks according to the invention relative to one another, because both guide tracks can be attached to a one-piece manipulator housing.
  • auxiliary steering lever according to the invention results in a functionally reliable, robust and structurally simple kinematics for guiding the pouring tube.
  • the resulting movement path for the pouring tube can be easily adapted to the respective space conditions of the overall system.
  • the said displacement member is designed in particular as a chain drive and arranged in the support frame such that the connecting element fastened to it and thus the pouring tube performs the web-shaped movement.
  • a robust and steelwork-compliant displacement member of the manipulator according to the invention is thus created.
  • a piston / cylinder unit can also be provided as a displacement element for a connecting element instead of a chain drive.
  • the manipulator is preferably positioned on its side facing the container on a support arm of a device for connecting the pouring tube to the spout of the container.
  • the manipulator guides the pouring tube into the vertical position and hangs it in the fork-shaped support arm by disengaging the connection between the support ring of the pouring tube and the connecting element.
  • This manipulator can of course also be used to remove a pouring tube from the support ring.
  • FIG. 1 shows a container 10 with a pouring opening 11, which is indicated by a hint of molten metal.
  • a slide closure or the like arranged on the container 10 can be arranged below the opening, or a refractory pouring tube 12 can also be connected directly.
  • the pouring tube 12 protrudes into the molten metal located in a continuous casting mold 13 and it is pressed onto the spout of the container in a conventional manner by a support arm 16 of a device 15.
  • the support arm 16 is, for example, vertically displaceable in the direction of the pouring tube axis by a piston / cylinder unit 17 and, moreover, is arranged to be pivotable or longitudinally displaceable in the horizontal direction by a device (not shown).
  • the support arm 16 has a fork-shaped design at both ends, in each of which a pouring tube 12 or. 14 can be attached. This basically creates the prerequisite that this device 15 can also be used to change the pouring tube.
  • a manipulator 20 enables the pouring tube 14 to be mechanically brought in and suspended in the support arm 16.
  • the pouring tube 14 is accordingly replaced by a approximately horizontal position P1 pivoted into the molten metal of the mold and then brought into the vertical end position P3.
  • the manipulator 20 has a support frame 22 which has a rail 23 at the bottom in the direction of the advancement of the pouring tube with tracks 23 'provided on both sides, in each of which two rollers 25 of a slide 24 run.
  • the carriage 24, for its part, has four further rollers 26 at the bottom, which run in a rail 28 which is arranged transversely to said rail 23 and is fastened on the mold 13, two tracks 29 which guide the rollers 26 being incorporated in the rail 28.
  • the manipulator can be loaded with the pouring tube 14 from an easily accessible point, then automatically brought into the vicinity of the vessel spout by means of the former rail 28, or even better by a drive, not shown, and with the other rail 23 struck on the support arm 16 of the device 15 and positioned exactly opposite it.
  • the manipulator 20 could also be arranged on a trolley and positioned on the support arm 16 by means of this.
  • the manipulator 20 has a connecting element 30 on both sides in its supporting frame 22 and a displacement element carrying this, which in the present exemplary embodiment is designed as a chain drive 40.
  • the chain drive 40 consists of an endless chain 41, two sprockets 43, 44 which guide these, each with an axle 45, 46 mounted in the support frame 22 and a drive pinion 47 which is rotatably connected to the axle 46 and is driven by a drive (not shown).
  • a similar chain drive 40 is provided for each connecting element 30.
  • the connecting element 30 is fastened to a chain link of the chain 41 and has a polygonal bolt 31 which is displaceably mounted transversely to the chain, by means of its displacement into a corresponding polygonal hole 18 of a bearing pin 19 arranged on a support ring 14 'of the pouring tube 14, the pouring tube 14 is held in the manipulator becomes.
  • the displacement of the bolt 31 takes place by means of a switching mechanism 50, in which, starting from a rotatable switch 51, a rod 53 rotatably mounted in the support frame 22 with grippers 54, 55 is rotated via an articulated connection 52, and thus in an annular groove 31 ′ of the bolt 31 guided gripper 54, 55 cause the displacement of the bolt. It is advantageous here that the pouring tube 14 can be connected or detached from the connecting elements 30 in the stationary state.
  • the sprockets 43, 44 are each mounted on one end of a side wall of the support frame 22, the sprocket 44 being arranged somewhat higher than the wheel 43 and thus the chain executes an approximately fifteen-degree inclination with respect to the horizontal in the longitudinal movement.
  • the sprocket 43 facing the container is moreover arranged in such a way that the chain 41 running on its periphery, after the straight, inclined guideway 40 'formed, causes the bearing journals 19 of the support ring 14' to open exactly into a groove-shaped groove 16 'of the support arm 16. This is preferably done by rotating the wheel 43 and thus the connecting element 30 after its rectilinear movement through an angle of approximately 60 to 90 °.
  • the respective bearing pin 19 has a centering tip 19 ′ which is formed at the bottom and corresponds to the groove 16 'mentioned; Any deviations between the position of the groove 16 'and that of the bearing pin 19 can be easily compensated for.
  • the bearing pins also have transverse end faces 19 ′′, which center the casting tube in the support arm 16 transversely to the longitudinal axis of the pouring tube with almost no play.
  • the respective connecting element 30 also has an auxiliary steering lever 32, one end of which has a bush 33 which is rotatably mounted in the connecting element 30 and holds the bolt 31, while the other end has a sliding roller 35 which is guided in an additional guideway, this guideway 34 to the path formed by the chain 40 'seen in the direction of moving the pouring tube 14 continuously apart at an angle of approximately 20 °.
  • the auxiliary steering lever 32 is arranged approximately coaxially with the pouring tube axis.
  • the guide track 34 is bent in the same direction at the end facing the container 10 in accordance with the rounding formed by the chain 41. This results in a uniform feeding and turning of the pouring tube from the approximately horizontal to the vertical position, with which the pouring tube can be inserted easily and very precisely in very tight spaces.
  • This auxiliary steering lever can be dispensed with, in particular for smaller pouring tubes or if space permits, and the pouring tube is then to be fastened to the connecting elements 30 in its longitudinal axis parallel to the straight chain path in position P1.
  • the support frame 22 consists essentially of two side walls carrying the displacement members and a crossbar connecting these two.
  • the axes 45 of the front sprockets 43 are extended towards the inside of the support frame 22 and each form a centering pin, which can each be snapped into a corresponding recess 16 ′′ of the fork-shaped support arm 16 and center the manipulator 20 to the container 10.
  • the connecting elements 30 When handling the manipulator 20, the connecting elements 30 are initially moved into the upper end position P1. By means of the switching mechanism 50, the bolts 31 are pushed back by actuating the rotary switch 51. Then the pouring tube is inserted into the support frame 22 corresponding to the position P1 and the bolts 31 are inserted into the polygonal holes 18 of the support ring 14 ', whereby the pouring tube is held in the manipulator. Now the support frame 22 can be moved into position by means of the rails 23, 28 and the slide 24 running therein, the centering bolts of the axes 45 into the recesses 16 '' of the support ring 16 and thus the pouring tube can be brought in manually or by a drive by moving the chain 41 in the direction of the container 10.
  • the pouring tube is brought into the vertical position P3 via the position P2.
  • the support ring and thus the pouring tube are now in the support arm of the pouring tube changing device 15, the bolts 31 can in turn be moved back via the switching mechanism 50 and the pouring tube can thus be released by the manipulator.
  • the manipulator 20 is then moved away from the support arm 16 and the new pouring tube 14 can be used instead of the pouring tube 12 located under the spout, which has been used up after a certain time.
  • the pouring tube 12 can then be moved out of the mold on the opposite side by the manipulator 20.
  • FIG. 3 and 4 show another embodiment of a manipulator 65, in which instead of a chain drive there is provided a guide track 56 corresponding to this and a connecting element 60 guided therein, which is moved back and forth by a piston / cylinder unit 63 as a displacement member is moved.
  • the connecting element 60 in turn has an auxiliary steering lever 60 'which, with its sliding element 62, is guided at one end in a second guideway 64 and its longitudinal axis is arranged approximately parallel to the pouring tube axis.
  • the guideways 56 and 64 are also formed in a support frame 59, which consists of one or two side walls and a crossbar.
  • a pin 66 Coaxial with the sliding block 61 of the connecting element 60 provided in the guideway 56 is a pin 66 which holds the pouring tube 14 and can be locked or disengaged therefrom. Otherwise, this manipulator 65 is similar in principle to that according to FIGS. 1 and 2 and therefore not all details are shown and described.
  • a connecting element 70 is provided instead of the connecting element 30 and the associated switching mechanism 50, which is also fastened to the chain 41. It has a plate-shaped fork 70 ', which is arranged between the chain 41 and the pouring tube 14 attached to it.
  • the pouring tube 14 is held in a metal support ring 49, which has a square support pin 49 'on each side, which can be inserted into a recess of the fork 70' with almost no play.
  • the recess is arranged with respect to the support frame 22 in such a way that it is opened approximately vertically upward in the position P1.
  • the fork 70 ' is also rotatably mounted in the connecting element 70 and is additionally rotated by its rotary connection with the auxiliary steering lever 32 when the pouring tube 14 is brought closer, as a result of which the pouring tube can be introduced in an optimal movement path.
  • bearing journals 49 ′′ arranged on both sides of the support ring 49 also enable transfer of the pouring tube, for example to a pouring tube changer 15, as already described above.
