Definitions

  • the invention relates to an assembly device for lining of a converter.
  • Both types of converter have a fireproof brick lining on that at the initial delivery and after the corresponding Wear must be created or renewed.
  • the invention is based on the object Offer delivery alternative that have the disadvantages and Difficulties eliminated as far as possible.
  • the assembly device comprises a scaffold, which in the area of the converter opening in the converter is hooked in. It comes down to a safe (stable) Attach the scaffold in the opening area of the converter to so that the scaffolding part protruding into the converter is one has a stable position.
  • the scaffold can be attached to a ring be attached or have a circumferential ring that on the edge area of the converter opening, for example Screw connection is attached.
  • About the inside diameter of the The size of the scaffolding can be defined at the same time.
  • the scaffold is also essential for the assembly device articulated mounting arm with gripping device.
  • the stones can be used individually or in Groups gripped by the gripping device and from the mounting arm brought to the desired installation location and set down there.
  • the corresponding control of the mounting arm can be done manually and / or automatically.
  • the gripping device can Have suction head, the stones with appropriate vacuum sucks and holds.
  • the Mounting arm and / or the gripping device in all directions the coordinate system is (are) movable. In this way it should be ensured that in principle every mounting arm pick up a stone at any point and anywhere Place.
  • Gripping devices are mounted on the scaffold, for example three Mounting arms on the outer circumference of the scaffold at an angular distance of approx. 120 ° each, the mounting arms also in height can be arranged offset.
  • the mobility of the mounting arm can, for example, by at least one swivel can be reached.
  • the mounting arm thus has the function of a robotic arm which in different sections is divided, the angle side can be adjusted to each other.
  • the transfer of the mounting arm and the associated Gripping device from a first position to a second Position can be accelerated if the mounting arm is designed telescopically. He can then simultaneously via the Joint at an angle and over the length of the telescopic part be adjusted.
  • the assembly and assembly time can be facilitated and accelerate when the scaffold is adjustable in length is trained.
  • a telescopic design of the Framework can be selected.
  • Another embodiment provides for the scaffold to be segmented to design, being individual, in the axial direction of the scaffold successive segments for extension or Shortening the scaffold hung one inside the other or from each other be decoupled, which is also in the following Figure description is explained.
  • the successive Segments have a different cross-section, so they are added from above or removed again from above can.
  • the scaffolding so that it is centered in the axial direction Has cavity that is free of internals.
  • This one, at cylindrical shape of the scaffold also cylindrical cavity can be used to feed personnel and material. So can walk along the stones, which are usually arranged on a pallet of the cavity in the converter and for example on be placed on the ground. It is also possible to have staff via a corresponding stage in the converter let down, the staff only control and Has surveillance tasks while putting the stones over the mentioned mounting arms with associated gripping devices he follows.
  • the assembly arms can be Required according to the progress of the delivery adjusted to the desired level. Your comprehensive Movement ensures delivery in all sections of Wall and floor of the converter.
  • a appropriate program the delivery more or less done completely automatically and for example via Sensors are monitored.
  • the assembly device described can also be used to cancel Lining material is used, with the mounting arms then, for example, instead of with gripping devices Compressed air devices or claws are formed.
  • the invention is based on a Embodiment explained in more detail.
  • a converter 10 is shown in FIG an (upper) opening area 12 a conical widening first wall section 14.1 and one attached to it adjoining cylindrical wall section 14.2, which merges into a convex base 14.3.
  • the bottom is 14.3 already with a complete refractory lining 16.3 provided while the areas adjacent to the wall sections 14.1, 14.2 still free of refractory material for a Are wear lining.
  • the scaffold 30 consists of several segments, of which the Segments 30.0 to 30.5 can be seen in FIG. 1.
  • the Segments 30.0 to 30.4 have the same overall height (in Axial direction A - A considered), while the segment 30.5 is shorter.
  • Each segment 30.0 to 30.5 has a cylindrical shape and is designed like a cage, it consists of a multitude of Longitudinal and cross struts, between which there is free space.
  • the uppermost segment 30.0 is stationary on the metal ring 18 attached.
  • segment 30.1 is stationary via closures 30.1v on the segment 30.0 attached. Accordingly, segment 30.2 is on the segment 30.1, segment 30.3 attached to segment 30.2 and so on.
  • closures consist of swiveling claws, which according to Art adjacent segments of a toggle lock, for example Connect 30.0 with 30.1 in a fixed but detachable manner. Any other Lanyards that meet the above criteria are possible.
  • the framework 30 has a stable cylindrical shape central, cylindrical cavity 30.6.
  • mounting arms 32, 34 On the lower segment 30.5 there are two diametrically opposite identical mounting arms 32, 34 articulated.
  • the structure the mounting arms 32, 34 is based on the Mounting arms 32 explained in more detail.
  • the mounting arm 32 consists of a 32.1 on a hinge subsequent first section 32.2, which is another Joint 32.3 is connected to a further section 32.4, which is followed by a joint 32.5 to which a section 32.6 connects that at its end a gripping device 32.7 wearing.
  • the gripping device 32.7 is designed so that a or several refractory bricks to line the converter 10 can be summarized.
  • Piston / cylinder arrangement 32.2b supports the safe Mobility of the mounting arm 32 under load.
  • Masonry stones can be placed over the cavity 30.6 Brick lining 16.3 deposited in the bottom area of the converter 10 become. From here, the mounting arms 32, 34 with their Gripping devices, for example the gripping device 32.7, grab one or more converter stones and on the desired position of the refractory to be created Brick lining 16.2 in the wall section 14.2 of the converter 10 lay down. Likewise, as the lining progresses along of the scaffold 30 a platform can be arranged to stones for to shut down the brickwork.
  • the scaffold 30 is then shortened by lifting it upwards out of the Opening area 12 is pulled until the segments 30.0 and 30.2 lie above the converter 10 and can be removed. Then the scaffold 30 with the segment 30.3 Metal ring 18 attached, as shown in Figure 1 in Connection with segment 30.0 was explained.
  • FIG. 2 also shows the position of the scaffold 30 shortened in this way the segments 30.3, 30.4 and 30.5.
  • the scaffold 30 can be restored to the previous one described way can be shortened, with the result only the segments 30.4 and 30.5 form the framework 30.
  • the conical wall is then bricked up further Wall section 14.1 of the converter 10 with a refractory Lining 16.1 to the opening area 12.
  • the lining in this area can also be achieved by directly attaching the Mounting arms 32, 34 take place in the opening area 12.
  • the mounting arms 32, 34 on the bottom Take refractory lining 16.3 stones, because the middle sections of the mounting arms 32, 34, like the Section 32.4 are designed telescopically (not shown) and an extension of the mounting arms 32, 34 to allow fire-resistant lining 16.3 on the bottom.
  • the scaffold will be erected dismantled and the converter can be put into operation.
