Definitions

  • the invention relates to a device with a liftable and lowerable horizontal assembly platform and a receiving means for mounting cooling segments on the inside of the steel sheet of a blast furnace.
  • blast furnaces have cooling plates or segments (so-called staves) arranged evenly distributed around the circumference between the outer steel or armor plate and the inner refractory lining.
  • Each cooling segment is attached to the steel sheet and has its own connections for the inlet and outlet of the cooling medium. These connections are led outside through holes in the armor plate.
  • the cooling segments - seen in a horizontal cross section - are either rectangular or in the form of a circular ring segment.
  • a mounting platform which can be adjusted in height by means of a lifting device and a further lifting device provided with a receiving means at the upper end of the blast furnace have hitherto been used.
  • the footprint of the assembly platform can be changed and thus adaptable to the respective diameter of the blast furnace.
  • the cooling segments while hanging on the upper lifting device, have to be pressed laterally towards the armor plates due to the taper of the blast furnace against at least a partial component of their gravity, which gives them a considerable weight of around 2.5 ... 6 t Difficulties connected and is accordingly time consuming.
  • time-consuming, sensitive changes in the position of the cooling segments are often necessary, both in terms of their height, their lateral position and their angular position.
  • the invention has for its object to design a device of the type mentioned for mounting cooling segments in such a way that the assembly of the cooling segments can be significantly accelerated.
  • the assembly platform has rails arranged concentrically to the axis of the blast furnace, that a support frame designed as a vehicle frame can be moved on these rails, which has a support part which can be moved relative to one another and on which the receiving means for the cooling segments is in turn arranged, wherein the receiving means has a substantially horizontal receiving part and a substantially vertical contact part, that adjustment means are provided for height adjustment of the receiving means relative to the assembly platform and for inclination adjustment in the longitudinal and transverse directions, and that the position of the Recording means is also adjustable about a vertical vertical axis and in the radial direction.
  • cooling segments are fastened to the steel sheet and each have a space or gap between them, the receiving part being able to move into the space. This makes it possible to mount the cooling segments both from the bottom up and from the top down. If the steel or jacket plate of the blast furnace is initially only present in the upper region of the blast furnace frame, the top rows of cooling segments can already be installed with the device according to the invention. By lowering the assembly platform, the lower-lying rows of cooling segments can be used - unlike with a receiving means that attacks from above, e.g. a crane hook - then be assembled. If necessary, individual cooling segments can also be replaced.
  • the rails arranged around the axis of the blast furnace make it possible to leave a central passage in the assembly platform.
  • a heavy central hoist can pass through the opening and be used to assemble other, heavy parts of the blast furnace.
  • a swivel arm is mounted on the support or vehicle frame, on the movable end of which the receiving means for the cooling segments is arranged.
  • the effective radius of the receiving means for the cooling segments (hereinafter also referred to as "cooling segment receptacle") can be changed over a wide range, the radial alignment of the cooling segment receptacle with respect to the blast furnace or to a horizontal plane thereof due to the pivotability the cooling segment can be mounted in relation to the swivel arm.
  • the adjustment means for height adjustment the height of the cooling segment receptacle can be sensitively changed relative to the mounting platform which can be roughly adjusted in height.
  • the inclination of the cooling segment receptacle can also be adapted to the local conditions of the blast furnace.
  • the adjustment means can be summarized both for the height adjustment and for the bank angle.
  • these are preferably designed as hydraulic cylinders arranged separately under the cooling segment receptacle.
  • the hydraulic cylinders are operated simultaneously and to the same extent and to adjust the inclination differently.
  • the means for height adjustment are arranged only at the front end under the hinge.
  • the one made at one end only The change in inclination of the cooling segment receptacle that occurs when the height is adjusted can be corrected by means of the specially provided adjustment device.
  • the construction carrying the cooling segment receptacle according to claim 6 consists of a subframe pivotably mounted on the pivoting arm and a frame supported on this, the position of which can be adjusted relative to the subframe is.
  • the device for mounting cooling segments 1 has a supporting structure 3 which is supported in the upper part of a blast furnace 2 and on which lifting devices 4 are arranged which are evenly distributed over the circumference and by means of which a mounting platform 5 can be raised and lowered within the blast furnace 2 by means of ropes 6.
  • the assembly platform 5 has radially oriented, telescopic cantilever beams 7, with the aid of which the area of the assembly platform 5 can be enlarged in a known manner.
  • the assembly platform 5 has a recess 8 through which the receiving means, e.g. a crane hook, a central lifting device 9 can be carried out.
  • the cooling segments 1 can be gripped both by a lifting device 9 arranged in the middle of the upper support frame 3, pulled through the recess 8 and placed on the receptacle 28, and introduced through an opening in the upper region of the blast furnace and by one in the upper region of the blast furnace located further lifting device 9 'are placed on the assembly platform 5 or the receptacle 28.
  • a so-called king column 20 with a vertical axis around which a swivel beam or swivel arm 21 is pivotably mounted and in any way, e.g. can be driven via a (not shown) manually operated rotary drive.
  • an auxiliary frame 22 is in turn pivotally mounted about a vertical axis 23.
  • a frame 27 is mounted on this subframe 22 via three pendulum supports 24, 25, 26 with double joints, on which in turn the actual cooling segment receptacle 28 is arranged.
  • the drive of the vehicle frame 14 or the entire assembly carriage 13 takes place via the wheels 15 ', which are in the swivel range of the swivel arm 21 and the cooling segment receptacles 28.
  • These wheels 15 ' are rigidly connected to one another via their common axis and are connected together via the axis to a drive motor 18.
  • the running wheels 15 'on the rails 11 and 12' have different diameters which relate to one another like the diameter or radii of the rails 11 and 12.
  • the running surfaces of the running wheels 15 'are conical, both of them Treads each represent part of an (imaginary) conical surface, which is given by the diameter of the running wheel 15 'on the outer rail 11' and the radius of the rail 11.
  • the two other wheels 15 ⁇ can be designed analogously or individually mounted on the vehicle frame 14.
  • an adjusting device 29 designed as a pressure medium cylinder is provided between the frame 27 and the auxiliary frame 22.
  • a manually operated spindle drive with an easily accessible handwheel can also be provided as the adjusting device.
  • Two pendulum supports 24, 25 are supported on piston rods of hydraulic cylinders 31 and 32, which are mounted on or in the auxiliary frame 22.
  • a vertical guide column 33 which is immovable with respect to the base area, is guided in the auxiliary frame 22 without its own drive and is connected to the frame 27 via a guide 34 designed as an elongated hole connection.
  • This connection allows a relative movement of the frame 27 and thus the cooling segment receptacle 28 with respect to the auxiliary frame 22 in the longitudinal direction, but prevents a relative movement in the (horizontal) transverse direction.
  • the cooling segment receptacle 28 At the end located above the hydraulic cylinders 31, 32 is the cooling segment receptacle 28 with a horizontal, platform-like receptacle or Support 36 and a vertical system 37 mounted on the frame 27 via a horizontal hinge joint 38.
  • the cooling segment support 28 is connected with its vertical contact 37 to the rear end of the intermediate frame 27 via an adjusting or adjusting device 39 designed as a turnbuckle with opposite thread pitches, so that the inclination of the cooling segment receptacle 28 can be changed in the longitudinal direction, ie around the axis 38 , both clockwise and counterclockwise.
  • a pressure medium cylinder can also be used.
  • the pivot arm 21 of the assembly carriage 13 is shown in any position.
  • the swivel arm 21 (not shown separately) extends radially outwards, the diameter of the rails 11, 12 being dimensioned accordingly.
  • the swivel arm 21 must be pivoted laterally accordingly (cf. the dash-dotted line in FIG. 3).
  • the swivel arm 21 is pivoted radially inward toward the central recess or opening 8 of the assembly platform 5.
