Definitions

  • the invention relates to a device for installing and removing sink blocks for metallurgical vessels, in particular for pans, with a guide for the axial displacement of the sink block.
  • DE-Al-33 30 105 is only for pulling out
  • Described flushing device suitable device which consists of a frame which is attached to the bottom of the vessel.
  • a spindle is mounted in the frame, via which the force required for pulling out can be applied.
  • the disadvantage here is that it is difficult to eject the used sink because of the very limited space.
  • the object of the invention is to avoid these disadvantages and to provide a device which allows both the pulling out and the setting of sink blocks, on the one hand the sink to be installed can be brought into a position in which the application of a layer of mortar is easily possible and on the other hand, an exactly axial movement can be achieved during insertion.
  • a position should be provided in which the extracted sink can be easily ejected.
  • the device is therefore designed such that joints are provided which allow at least two independent pivoting movements of the sink around different axes.
  • the metallurgical vessel is usually brought into the lying position in which the bottom of the vessel is vertical and thus the axis of the sink is horizontal.
  • the guide ensures an exact axial movement of the sink, so that stripping of the mortar is prevented and a uniform joint is achieved.
  • another advantage of the invention is that the mortar can be easily freed of mortar residues after pulling out the sink.
  • the device will be attached to the vessel in such a way that the axis of one joint is essentially vertical, so that the pivoting can take place without any significant expenditure of force, since gravity cannot be overcome got to.
  • the second joint with a substantially horizontal axis serves to pivot the sink completely out of the area of the opening and to be able to bring it into a position with a vertical axis in which work on the sink is easily possible.
  • the layer of mortar required for a precise fit can be easily applied to the vertical sink in this way.
  • the guide contains a rail on which a carriage is slidably arranged. This enables the sink to be moved easily and quickly.
  • a particularly favorable design is given if a first joint allows the guide to be pivoted relative to the vessel and a second joint allows the sink to pivot relative to the slide.
  • the second joint can rotatably hold a head on the slide, which can be fixed by means of a locking device.
  • the setting and pulling out of the sink is made easier if a guide tube for manipulating the sink is axially displaceable in the head.
  • a tool for connection to the sink can be attached to the guide tube. This tool can be designed differently for setting the sink than for pulling out.
  • the device can have a receptacle for a pneumatic hammer. This jackhammer can be placed on the outer end of the guide tube.
  • Flushing stone is provided, which are arranged regularly around the axis of the flushing stone. You can also pull out the sink
  • two support punches are provided, the axes of which lie zxi on a plane which contains the axis of the sink, and which are located on the head
  • the device permanently to the vessel can remain ⁇ • ⁇ ⁇ ⁇ provided seir & 8 it has a coupling piece 25 to be able to fasten it ab ⁇ e iabar axr- Gefäfc.
  • a plate attached to the bottom of the vessel or to the sink flange is used during operation, which can be provided with a refractory backfill.
  • Joints or the guide can be easily compensated, so that an exact axial movement of the sink is guaranteed in any case.
  • FIG. 1 is a view of the device according to the invention from above when the sink is pulled out
  • FIG. 2 is a side view when
  • FIG. 3 is a view of the
  • FIG. 4th 5 shows a view corresponding to FIG. 1 when the sink is pulled out
  • FIG. 6 shows such a view on a reduced scale when the sink is pivoted
  • FIG. 7 shows a front view on a reduced scale in the position for throwing off the sink
  • FIG 8 is a front view, on a reduced scale, in the position for fitting a new sink.
  • 9 and 10 show a further embodiment of the device according to the invention, specifically in FIG. 9 in a view from above and in FIG. 10 in a side view. 1 and 2 is the position of the invention
  • the pan base 1 is brought into a vertical position by pivoting the vessel, so that the axis 17a of the sink 17 lies horizontally.
  • a sink flange 2 is provided on the pan base 1 in a known manner.
  • the axis 6a is essentially vertical
  • the axis 11a of the second joint 11 is attached to a head 12.
  • the second joint 11 is designed as a bolt which is fixedly connected to the carriage 9 and which engages in a corresponding bore in the head 12.
  • the axis 11a of the second joint 11 is perpendicular to the axis 6a of the first joint 6.
  • a disc 10a is also rotatably mounted on the bolt of the slide 9 and has several bores in the area of its circumference into which a locking device 10 can engage,
  • the disc 10a is connected to the head 12 via a fine adjustment 13 designed as a screw spindle.
  • the pivoting of the head 12 about the second axis 11a takes place by releasing the locking device 10 and jointly rotating the disk 10a and the head 12.
  • the fine adjustment 13 can Head 12 can be rotated slightly relative to the disc 10a, so that a precisely central insertion of the sink 17 is made possible.
  • a guide tube 14 is axially slidably mounted in the head 12.
  • the pliers 15a for pulling out the sink 17 are coupled via a bayonet lock.
  • the pliers 15a can be easily coupled to the gas connection pipe 16 of the sink 17 via a locking mechanism 19.
  • Attached to the head 12 are two hydraulic rams 21a and 21b which act on a pressure plate 24 which, during the extraction process, introduces the force into this guide tube 14 via a wedge 25 inserted into the guide tube 14.
  • the head 12 is supported on the sink flange 2 via support stamps 20a and 20b.
  • the support plunger 20a has been omitted from FIG. 1.
  • the hydraulic plungers 21a and 21b are connected via a schematically illustrated hydraulic line 22 to a hydraulic purope 23, which in the exemplary embodiment is designed as a hand pump, which is attached to the guide 7. 3 and 4 is on the guide tube 14
  • Pressure piece 15b coupled to set the sink 17.
  • the gas connection pipe 16 is inserted directly into the pressure piece 15 b and the guide pipe 14.
  • a pneumatic hammer 26 is placed, with which the force required for setting can be applied. The force is applied to the bottom plate of the sink 17 via the pressure piece 15b.
  • FIG. 5 shows the device 4 in a position in which the slide 9 is pushed into the outermost position on the guide 7 after being pulled out.
  • the carriage 9 is held in this position by the end stop 27.
  • Fig. 6 the guide 7 and thus the carriage 9 and
  • Axis 11a of the second joint 11 rotated by 90 ° so that the axis 17a of the sink 17 is substantially vertical and the sink 17 is directed downwards. In this position, the sink 17 can be easily dropped.
  • Fig. 8 the head 12 is rotated 90 "relative to the carriage 9 about the axis 11a of the second joint 11 such that the axis 17a of the sink 17 is substantially vertical and the sink 17 is directed upwards.
  • a new sink 17 is placed and the required mortar layer is then applied to this sink 17.
  • the sink 17 in this position is relatively far away from the opening 28 of the sink flange 2 and in particular is pivoted out of the area of the axis 28a which allows hot gases to flow out, thus making it possible to work undisturbed on the sink 17 and also ensuring that premature curing of the mortar layer is prevented.
  • the support rams used for the pull-out process are designed as hydraulic rams 30a and 30b which act counter to the pull-out direction.
  • the hydraulic rams 21a and 21b and the pressure plate 24 are omitted. All the steps for operating the supports are omitted, since the hydraulic rams 30a and 30b are extended by the hydraulic pump 23.
  • the stamps are retracted via a return spring in each hydraulic stamp.
  • the sink 17 is installed and pulled out with one and the same tool 31, which is a combination of pressure piece 15b and pliers 15a.
  • This tool 31 is screwed onto the guide tube 14.
  • the frictional connection for the extraction process is made between guide tube 14, inserted wedge 25 and slide 9.
  • this embodiment variant presupposes that the two hydraulic rams 30a and 30b run synchronously, because otherwise the device may be distorted.
