Definitions

  • the invention relates to a lifting device for heavy loads of elongated shape, in particular multi-axis pig iron transport wagons, so-called torpedo wagons.
  • Torpedo cars are used to transport molten pig iron from blast furnace systems to steelworks. They usually have 12 to 16 axles, a length of 20 to 30 meters and their unladen weight varies between 150 and 300 tons depending on the version.
  • the storage bolsters of the container are supported on both sides by 2 to 4 bogies, which are each equipped with 2 wheel axles and must be overhauled after fixed operating times. For this purpose, the ends of the torpedo body are detached from the stools and lifted off. During the maintenance of the subframe (a few days), the torpedo tube cools down so that it can possibly be given a new lining.
  • test bench for motor vehicles which can be raised with the aid of a lifting platform.
  • the test bench comprises two side members which are rigidly connected to one another via cross members. Supports and running wheels are arranged below the longitudinal beams, the latter coming into effect when the supports are partially removed.
  • the object of the invention is to propose a lifting device which avoids the above disadvantages, adapts to the inclinations of the load when lifting and allows the load to be set down in the desired position.
  • the advantages of the device are that the lifting and lowering process can be precisely controlled and observed from a safe distance.
  • the torpedo body always remains in a horizontal position, so that repair work with a full torpedo is now possible even in emergencies. It also does not get into an oscillating movement, as is customary with goods attached to cranes; it is particularly time-saving that the torpedo body can be moved with millimeter precision when loosening and fixing the subframe. Thanks to the new device, the torpedo bodies no longer need to be provided with special brackets for lifting.
  • a lifting device for torpedoes which in its basic structure consists of hydraulic double-acting lifting elements 1, which are articulated via bolts 3 on the walking beam 2; the walking beam 2 is articulated to the crossbar 7 by means of the support 6 and the bolts 4 and 5.
  • a first eye bearing (not shown) carrying the bolt 8 is welded to the crossbar 7 and a second eye bearing 14 carrying the bolt 8a is screwed on.
  • the two eye bearings are possibly provided with a plurality of holes which are offset in the longitudinal direction to the beam 7 and through which the bolts 8 and 8a can be pushed.
  • the saddle pieces 9 and 9a are rotatably mounted on the bolts 8 and 8a.
  • the screwing of the eye bearing 14 to the crossbeam 7 allows easy adjustment (by means of holes and longitudinal holes provided in the eye bearing 14) and quick removal of the saddle piece 9a.
  • An exact fit of the saddle pieces is only guaranteed if the curve dimensions, bow height and bow string the saddle pieces are matched to the respective torpedo body radius, ie different saddle pieces must be provided for different container diameters.
  • each crossbar 7 On the lower side of each crossbar 7, two supports 10 are welded (see FIG. 2). In addition to the supports 10, two suspension struts 11 are also attached to each crossbeam 7, which are supported on the floor by axles provided with two steel wheels 12. These axes run parallel to the lifting beam 2. The spring is dimensioned such that its force enables the device to be lifted without the lifting beam 2 and lifting elements 1. So there is a shift in the transverse direction in the unloaded state and a firm standing on the supports 10 (or when lifting, on the lifting elements 1) is ensured under load.
  • the two crossbeams 7 are connected to one another via two semi-trailing arms 13 (see FIG. 3). These semi-trailing arms are only advantageous when installing the lifting device. After assembly they should be unscrewed so as not to disturb the articulated setting of the device when lifting.
