Definitions

  • the invention relates to a method, in particular for repairing a slide closure on a vessel containing molten metal, and to a slide closure according to the preamble of claim 1 or claim 5.
  • a known sliding closure according to the publication EP-A-3 424 618 is equipped with a slide housing, a slide unit guided longitudinally therein with a push rod, a bracket and an in the latter removably attached linear drive provided with a drive rod.
  • This drive rod can be connected to the push rod of the slide unit by a coupling, which, when the linear drive is pushed into the holder, is coupled by moving the drive rod against the slide unit, while when the linear drive is removed from the holder, it is uncoupled transversely to the direction of movement of the drive rod.
  • At least one electrical line and/or media, such as gas or air, conveying connecting lines must be connected to supply sources away from the platform. This is usually done by manually plugging in the connection lines on the casting platform at the slide closure.
  • the invention is based on the object of creating a method for repairing a sliding closure, in which, in a structurally simple manner, improved handling for the assembly of the linear drive and the connection of plug-in connections for at least one electrical and/or one line connection for the supply of media , Such as gas or air, is made possible, and this should preferably be designed for execution by means of a robot or manipulator.
  • At least one electrical plug part and/or at least one valve plug part for the medium of the at least one connection line is assigned to the linear drive and the holder in pairs. In this way, when the linear drive is pushed into the holder, they can be automatically inserted and thus cause the connection of the respective connecting line or be automatically released when the linear drive is removed from the holder.
  • the linear drive is preferably inserted or removed from the holder transversely to its adjustment direction, and the connection lines are inserted or removed synchronously in the same direction. Due to the space available on the casting platform, this transverse insertion results in excellent accessibility for handling.
  • FIG. 1 and 2 show a holder 15 and a linear drive 12, which can be inserted laterally into this, of an indicated slide closure 10 with a slide housing 11 and a slide unit guided longitudinally in this, of which only one push rod 13 projecting into the holder 15 can be seen.
  • Such a sliding closure 10 is known per se in terms of structure and mode of operation and is therefore not shown in further detail. He suits preferably for a ladle containing for pouring molten steel as a vessel of a continuous casting plant. In principle, however, it could also be used at the outlet of other vessels, such as in a converter, a distributor or even in furnaces in the non-ferrous metal sector.
  • the linear drive 12 is usually only pushed into this holder 15 and coupled after the ladle filled with molten metal has been placed on a turret on a casting platform of the continuous casting plant.
  • This is preferably done by a robot arranged on the casting platform, which automatically determines the exact position of the holder 15 of the sliding closure 10 by means of a detection system that can be mounted on it and then grasps the linear drive 12, which is designed as a hydraulic piston/cylinder unit, from a storage location using a corresponding gripping tool. leads to the sliding closure 10 and pushes it into the holder 15. When removing the same, this is done in reverse order.
  • connection lines 16, 17, 18 are connected to an external power, gas or air pressure source with associated control devices and are coupled for repair by plugging operations on the casting platform at the slide closure 10.
  • this plugging process of the connecting lines 16, 17, 18 takes place with the insertion of the linear drive 12 into the holder 15 or, when loosening, with the removal of the same from the holder 15 automatically.
  • connection lines 16, 17, 18 are inserted or removed in the same direction.
  • connection lines are plugged in, they are centered first and then move into the plugged-in position.
  • the linear drive 12 and the holder 15 are expediently each provided with at least one guide means which are designed in such a way that the linear drive 12 can be pushed transversely into the holder 15 or removed from it.
  • the guide means for the linear drive 12 is at the front, where its drive rod 12' is located, and that at the holder 15 is arranged at the rear at the free-standing end.
  • These guide means are preferably designed as an approximately rectangular flange 22 in the case of the linear drive 12 and as corresponding guide grooves 25 ′ in a C-shaped receiving part 25 in the case of the holder 15 .
  • This flange 22 can be pushed in and out of these guide grooves 25', which are arranged parallel one above the other, of the receiving part 25 and is held in a form-fitting manner during the casting process.
  • the guide grooves 25' are arranged inclined inwards at a few degrees to the horizontal. This ensures that the linear drive remains securely in the holder, without an operable locking means having to be used.
  • the flange 22 of the linear drive 12 also has a laterally extending holding element 20 which can be gripped by the gripping tool of the robot. However, the linear drive 12 can also be carried manually.
  • connection lines 16 , 17 , 18 are guided along the front side of the holder 15 to the sliding closure 10 and at the rear along the linear drive 12 designed as a cylinder 19 .
  • the holder 15 has a wall 15' on one longitudinal side, along which the connecting lines are routed, and is open on the other longitudinal side, so that the drive rod 12' with the coupling head 14 can be inserted therein. From the linear drive 12 these connecting lines are routed in bundles through a sleeve 21 protruding at the rear of the cylinder 19 and at least one hose (not shown in detail) to these external supply sources. This results in a further advantage of a compact, secure routing of these connection lines 16, 17, 18.
  • FIG. 3 to 6 shows, according to the invention, one electrical plug part 26, 36 and two valve plug parts 27, 28 37, 38 for the medium of the connecting lines 16, 17, 18 are assigned in pairs to the linear drive 12 and the holder 15 in such a way that when the linear drive 12 automatically plugged into the holder 15 and thus bring about the connection of the connection lines 16, 17, 18 or the same are automatically released when the linear drive 12 is removed from the holder.
  • One electrical connector part 26 is above the cylinder 19 and the corresponding connector part 36 is laterally above the receiving part 25 are arranged free-standing in the holder 15, while the plug-in valve parts 27, 28 for the medium protrude at the front of this flange 22 and the two corresponding plug-in valve parts 37, 38 are fastened on the inside in the receiving part 25, so that the plug-in parts 26, 36 or the plug-in valve parts 27 , 28, 37, 38 are plugged into one another in the receiving part 25 when the flange 22 is pushed into these guide grooves 25'.
  • a centering means is provided for the prior centering of the pairs of corresponding male valve parts 27, 28, 37, 38 when plugging.
  • a protruding centering pin 29 is arranged on the flange 22 and, on the other hand, a receiving sleeve 29' is arranged in the receiving part 25 as a centering means.
  • the centering pin 29, which is approximately pointed at the front, is dimensioned longer than the valve plug parts 27, 28, so that when the flange 22 is pushed in, it reaches the receiving sleeve 29' before the valve plug parts 27, 28, 37, 38 are pushed into one another.
  • the plug-in valve parts 37, 38 with the receiving sleeve 29' are advantageously held in a plate-like device 34, which is mounted floating in the holder 15 transversely to its longitudinal extension, in order to compensate for deviations from the plug-in valve parts 27, 28 in the flange 22. This ensures that this plug-in process can be carried out correctly and with tolerances that conform to steelworks standards.
  • the flange 22 which is also provided with bevels 22' on the side at the front as a centering aid, is pushed into the guide grooves 25' of the receiving part 25.
  • the centering pin 29 comes in first this receiving sleeve 29', so that the valve plug-in parts 27, 28, 37, 38 are already pre-centered with respect to one another as they are pushed in further.
  • the valve plug-in parts consist of known sleeve and closing elements with seals, which are not explained in detail.
  • a ratchet lever 24 of a ratchet mechanism 23 can also be seen, by means of which automatic transport security is ensured.
  • a plug-in stroke limiting pin 33 is shown, which engages in a longitudinal groove in the push rod 13 in order to serve as a stop for the stroke of the latter.
  • a socket 31 is included in one plug part 26, while the corresponding plug pins 37 protrude in the other plug part 36.
  • These plug parts 26, 36 are also centered with the centering via this centering pin 29 in the receiving sleeve 29.
  • one plug part 26 is articulated or floating on the cylinder 12' by means of an indicated device 39, so that it avoids inaccuracies during the plugging process can compensate.
  • a hinged cover 32 is also preferably provided for the plug part 36, by means of which the opening in this plug part is closed in the unplugged state in order to prevent contamination in the same.
  • the connecting lines 17, 18 are arranged on the side of the flange 22 next to the cylinder 19 on the side near the valve plug-in parts 27, 28 placed on the face side of the flange 22, with which they are connected.
  • Both these electrical plug parts 26, 36 and the valve plug parts 27, 28, 37, 38 are also designed in pairs in relation to one another such that they each reach the plugged state before the end position of the flange 22 has been reached in the holder 15 and over the remaining insertion path in the plugged condition are. This has the advantage that if the flange cannot be inserted into the end position due to contamination or the like, the electrical or media connection is still provided over a certain distance of, for example, 10 to 15 millimeters before the end position.
  • connection line be it electrical or for a medium, or more than three of them can be provided.
  • the plug parts 26, 36 for the electrical connection line could also be arranged like the valve plug parts on the side of the flange or on the inside of the receiving part, in which such and at least one valve plug part could also be provided.
  • the valve plug parts could be arranged above the cylinder 19 like the plug parts.
  • linear drive 12 as a flange 22 and in the case of the holder 15 as corresponding guide grooves 25' in a C-shaped receiving part 25 could be designed differently, for example that the guide grooves were formed in the flange 22 and the receiving part 25 would engage in them .
  • the linear drive 12 usually uses a hydraulic piston/cylinder unit, but it could also be an electric drive.
  • the guide means and thus the insertion direction of the linear drive 12 and the plugging process could be inserted or removed from the holder in the adjustment direction or from the side from the bottom up instead of transversely to the adjustment direction A of its drive rod 12′.
  • the guide means and the plug parts or valve plug parts would then have to be arranged accordingly, so that according to the invention this plugging of the at least one connecting line can take place automatically when the linear drive is pushed into the holder or released when it is removed from the holder.
