Definitions

  • the invention relates to a device for holding and changing a submersible lance which can be connected to a feed line via a spring-loaded plug-in and sealing device.
  • the object of the present invention is to propose a device which is able to hold a diving lance in a simple manner and to prevent it from falling out, and which, if appropriate, allows automatic changing.
  • the device according to the invention is characterized by a gripper and support arm connected to a drive via a linkage with a drive and pivotable about a horizontal axis in the operating position, the gripper and support arm, the linkage and as well as the insertion and sealing device on one common base plate are attached.
  • the drive consists of a hydraulically operated cylinder.
  • the linkage itself is designed so that during the diving lance insertion or. Sealing process describes curves that cross an imaginary line, whereby the plunger is automatically locked by the spring assembly, even if the hydraulic pressure fails.
  • Another unit of the device according to the invention consists of a diving lance holder which is adapted to the holding device and which allows the diving lance to be changed without any problems and without manual intervention.
  • FIG. 1 shows an immersion lance 1 which comprises at its upper end a tube (2) which, at a certain distance from each other, has a pair of nozzles 3 and 4 offset by 180 °.
  • the nozzles 3 and 4 are preferably formed by round rods or thick-walled tubes, and are connected to the tube 2 in solidarity.
  • the tube 2 can be connected in various ways with the immersion lance 1, for. B. by screwing or flange.
  • a seal 5 which in the preferred embodiment is made of soft material, for. B. consists of an O-ring made of Viton.
  • an arm 6 of a lance holder can be seen, which receives the immersion lance 2 via the two nozzles 4 which are offset by 180 °.
  • a holder 7 is attached, which is connected to a guide device which, for. B. is described in the aforementioned document EP-A-56 944.
  • a gripper 8 is rotatably mounted on the holder 7 via an axis 9.
  • the gripper 8 is moved about the axis 9 via a linkage 10 and 11 and a hydraulic cylinder 12.
  • the cylinder 12 and the linkage 10 and 11 are rotatably mounted on the bracket 7 via axes 13 and 14, respectively.
  • the linkage 10 and 11 is connected to one another via a further axis 15, the rod 11 at its end opposite the axis 15 via an axis of rotation 17 to the
  • the piston rod of the cylinder 12 and the rod 10 are connected at their end opposite the axis 15 to the gripper 8 via a further axis 16.
  • the rod 11 can preferably also be designed as a triangle as shown in FIGS. 1 a, 1 b, 1 c.
  • a sealing device 18 is attached to the holder 7, which essentially comprises a pneumatic delivery line 19 fastened by screwing, a collecting funnel 20 provided for the tube 2, a spring assembly 21, and a spherical support surface 22 of the tube 2.
  • FIGS. 1b and 1c The mode of operation of the device according to the invention can be seen from FIGS. 1b and 1c.
  • the piston rod of the cylinder (12) is extended. This movement is passed on to the gripper 8 via the linkage 10 and 11 and via the axes of rotation 14, 15, 16 and 17.
  • the gripper 8 rotates about its axis of rotation 9 and comes into contact with the tube 2 via the two connecting pieces 3, which are offset by 180 °, and lifts the tube 2 with the immersion lance 1 out of the immersion lance holder 6.
  • the tube 2 comes via the seal 5 in contact with the support surface 22.
  • the spring assembly 21 is now compressed and ensures absolutely reliable contact between the seal 5 and the support surface 22, which is required for the pneumatic transport.
  • a preferred embodiment of the device according to the invention consists in that during the extension of the cylinder 12, the axis 15 crosses the imaginary line between the axes 14 and 16. This ensures that the dead center of the system is exceeded, i. H. automatic self-locking of the gripper 8 is ensured.
  • the self-locking system can only be unlocked via the cylinder 12. This is of great advantage since the cylinder 12 is only required for moving the gripper 8 and the sealing during the operation of the immersion lance 1 is carried out by the system as described above.
  • the embodiment according to the invention is particularly advantageous if the cylinder 12 fails during the blowing.
  • the gripper 8 on the other hand the nozzles 3 and 4 and the immersion lance holder 6 are designed in such a way that when the gripper 8 is open (FIG. 1a) the immersion lance holder 6 rotates and when the gripper 8 is closed (FIG. 1c) Moving the entire sealing device 18 with the immersion lance 1 is guaranteed.
  • FIG. 2 shows the side view of a preferred embodiment of a submersible lance quiver on a centrally arranged rotary table 23 which is rotated via an electric motor 24 and a gear 25.
  • the rotary table 23 comprises a vertical king column 26, which is slightly conical at the top, for receiving the diving lance quiver.
  • the submersible lance holder mainly consists of a central tree 27 which understands a certain number of lance holders 6a, 6b, into which submersible lances 1a, 1 are suspended via the connecting pieces 4a, 4b.
  • An eyelet 28 is also provided for receiving a crane hook (see FIG. 3). So that the immersion lances 1a, 1b remain in a vertical position during transport, holders 29a, 29b are provided, into which the immersion lances 1a, 1b are inserted at their lower end.
  • the central tree 27 has a conical attachment 30, which automatically ensures centering together with the royal column 26.
  • the immersion lance holder is rotated so that the immersion lances 1a, 1b are always brought into a specific position. In a preferred embodiment, this can be done e.g. B. Limit switches can be reached. Furthermore, the rotation of the plate 23 can be achieved with the aid of a cylinder.
  • a displaceable quiver can also be used in which the lances are suspended in rows next to one another.
