Definitions

  • the present invention relates to a scaffold changing device for continuous casting plants, in particular for manipulating strand supporting and guiding scaffolds of multi-core curved continuous casting plants.
  • the present invention is therefore based on the object to develop a device that allows the installation and removal of all strand support and guide frames of a continuous casting system with two or more strands in case of casting disruption and format change quickly, easily and safely to accomplish.
  • the stand changing device which is characterized in that a base body is mi't chassis on rails below the casting platform disposed transversely moved to the casting direction and a single parallel to the casting direction and carries ausfumblerbaren pickup arm of the H certainalachse is pivotally arranged in the vertical plane and at the end of which there is a support and clamping device pivotable about the horizontal axis in the vertical plane.
  • the rails over which the undercarriage with its own drive moves run under the across the entire casting area to a storage area.
  • the receiving arm of the scaffolding changing device has an extension and retraction mechanism which is designed such that the travel length exceeds the depth of the scaffolding to be installed or removed.
  • the scaffolds captured by the carrying and clamping device can be moved past the interference edges of the neighboring scaffolds and cooling chambers.
  • the pivoting mechanism of the receiving arm is designed in such a way that the executable pivoting dimension is at least equivalent to the curved dimension described by the strand support and guide frames. This means that any scaffolding on any segment of the arch that the strings are lined up with can be easily reached by the carrying and clamping device located at the end of the arm.
  • the swivel mechanism is designed so that there is a swivel dimension of at least 90 ° around the axis. It is therefore sufficient to provide each scaffold with two fastening points into which the carrying and clamping device can snap after the device, the arm and the clamping device have been positioned accordingly.
  • the scaffolding is attached regardless of the position of the carrying device.
  • a preferred embodiment of the scaffolding changing device provides that the drive for moving the base body, the retracting and extending mechanism of the receiving arm, as well as the pivoting mechanisms of the receiving arm or the carrying and clamping device have control elements which are connected to a central control point.
  • FIG. 1 shows a vertical longitudinal section through an arc continuous casting installation which is equipped with a possible embodiment of the scaffolding changing device according to the invention.
  • the base body (1) of the scaffolding changing device is arranged so as to be movable transversely to the casting direction via rails (2) with a drive (not shown) on rails below the casting platform (12).
  • the rails extend beyond the width of the casting machine a storage area where the scaffolding can be placed on a scaffolding template at any level below the casting platform and new scaffolding can be picked up using the scaffolding changing device.
  • the base body (1) On the axis (3) transversely to the casting direction, the base body (1) carries a receiving arm (4) which can be pivoted about this axis (3) and moved in and out.
  • an axis (5) is arranged transversely to the casting direction.
  • the support and clamping device (6) which can be pivoted about this axis (5) is attached here. With the help of the support arms (7) and the locking device (8), any frame (10) of a continuous casting system can be captured at the attachment points (9) provided for this purpose.
  • each scaffold of a multi-core continuous casting system By superimposing the two possible movements of the receiving arm (4) and the possible movement of the carrying and clamping device (6), it is possible to pass each scaffold of a multi-core continuous casting system past the interference edges of the scaffolds lying next to it and the cooling chamber (11) into one for to bring the removal to a convenient location and to transport it out of the casting area transversely to the casting direction by moving the scaffold changing device.
  • All movements of the scaffolding changing device can be carried out electromechanically or hydraulically and can be controlled remotely.
  • a particularly favorable embodiment of the device according to the invention provides for the attachment of a cutting torch to the carrying and clamping device (6). This makes it possible to cut a strand that has got stuck while the casting operation is running, without having to wait for the end of the casting.
  • the cutting torch is turned into the desired position by controlling the holding arm
  • the flame cut is carried out particularly conveniently by moving the scaffold changing device transversely to the casting direction.
