Definitions

  • the invention relates to a method for converting a heavy load with a vertical height to be overcome and a stopper aid for hoists according to the preamble of claim. 6
  • the method according to the invention for implementing a heavy load provides that a first vertical portion of the lifting height is provided by a hoist, that a second vertical portion is provided at the lifting height by a attached to another attachment means of the hoist telescopic device, and that the first together with the second part results in the lifting height.
  • a stop aid according to the invention for hoists is characterized in that the connecting element is a telescopic device, and that by the telescopic device, the distance between the first and the second connection element is variable.
  • the stop aid according to the invention By means of the stop aid according to the invention, it is achieved in an advantageous manner that for a vertical transfer operation for heavy loads, the stop aid can make an additional vertical contribution to the turnover process. In this way, Umsetzvor réelle that can not be made in a lifting operation by the hoist itself, made possible by the inventive stop aids.
  • the flexibility of the hoist with the stopper aid according to the invention is increased in an advantageous manner. In addition, the conversion process for heavy loads under the aforementioned boundary conditions is simplified.
  • An advantageous embodiment of the stop aid according to the invention is characterized in that the telescopic device is a scissors gear.
  • the scissors gear as a telescopic device, a mechanically favorable configuration of the connecting element is achieved, wherein the tensile and compressive forces in the bars of the scissors gear are comparatively easily controlled.
  • the design of the scissors gear is particularly simple. Another advantage is that various fail-safe concepts, for example in the form of an assumed break of a bar of the scissors gear or a drive rod, are relatively easy to control.
  • Fig. 1 shows a section of a fuel storage pool 10 in a nuclear power plant as a sketch.
  • a castor transport container 14 for fuel elements of the nuclear power plant is parked in a first parking position 13 on a pool bottom 12 of the fuel storage tank 10.
  • the depth of the fuel element storage tank 10 between a water surface 16 of the filled with deionized water fuel storage tank 10 and the pelvic floor 12 is approximately two and a half times the height of the Castor transport container 14. This is approximately cylindrical and with one of its end faces on the pelvic floor 12 parked.
  • the same castor transport container 14 is also shown in a second parking position 18, in which it is namely located on a pedestal 20 on a basin floor 22, and thus in this illustration is arranged laterally next to the fuel storage tank 10.
  • a building wall 24 is only partially shown and configured at a certain height above the pool floor 22 as a support 26 for a crane bridge 28.
  • the crane bridge 28 is shown in the background as a lateral plan view. so that a crane hook 30 is shown cut free from its suspension ropes 32.
  • the crane hook 30 is disposed below the crane bridge 28 located in the background, although this is not readily apparent from this figure due to the perspective view of the crane bridge 28.
  • the crane hook 30 is also shown in a second position, in which a stop aid 34 attached to the crane hook 30 by means of bolts 36.
  • the stopper aid 34 has on the side facing away from the bolt 36, a cross member 38 which is configured so that in each case a vertical support 42 is disposed on a horizontal beam 40, respectively in the vicinity of its ends, each as a receiving element, the two trailer elements on Castor Transport container 14, here in its second parking position 18, serve.
  • a scissors gear 44 is used as a connecting element between the bolt 36 and the cross member 38 and shown in the second parking position 18 in a comparatively short distance between the bolt 36 and cross member 38.
  • FIG. 1 A further illustration of the crane hook 30, the stop aid 34 and the castor transport container 14 is likewise shown in FIG. 1 for the first set-up position 13.
  • the components in the first parking position 13 or in the second parking position 18 are provided with identical reference numerals.
  • An essential difference between the situation of the stop aid 34 in the first parking position 13 compared to the second parking position 18 is that the distance between the pin 36 and the cross member 38 in the first parking position 13 is large compared to the corresponding distance in the second parking position 18 , In this way, the crane hook 30 remains above the water surface 16, while the castor transport container 14 is already on the pelvic floor 12, so that in a step not shown here, the vertical support 42 can be knocked off the Castor transport container 14.
  • the inventive method for implementing a heavy load will now be explained in more detail with reference to the situation shown in FIG.
  • the heavy load to be implemented in the example shown in FIG. 1 of the Castor transport container 14.
  • Such designated as castors fuel transport containers usually take several fuel for transport purposes between the power plant and its manufacturing or reprocessing facility.
  • a loaded with fuel elements Castor containers typically weigh at least 25 tons, but can easily weigh up to 120 tons, depending on the size of the Castor container.
  • FIG. 1 illustrates a typical loading or unloading situation for the castor transport container 14 in which it is moved from the first parking position 13 into the second parking position 18 or vice versa.
  • the case to be overcome lifting height is the geodetic height difference between the second parking position 18 of the Castor-transport container 14 on the pelvic floor 22 and the first parking position 13 on the pelvic floor.
  • the implementation of the Castor transport container 14 is carried out as follows, in the event that it is in the second parking position 18. First, the Castor-transport container 14 is raised slightly so that it is lifted from its base 20 defined and freely movable in the horizontal direction. This lifting can be done by slight contraction of the scissors gear 44 or by the crane. By moving the crane trolley, the castor transport container 14 is now moved vertically until its vertical end position is reached. In a next step, the crane hook is lowered by the crane as far as possible due to the structural conditions of the crane.
  • the crane hook 30 is usually not allowed to be submerged in the water of the fuel storage pool 10.
  • the Castor transport container 14 has not yet reached its final storage position in the fuel storage tank 10.
  • the distance between the bolts 36 and the traverse 38 is continuously extended by the scissors gear 44. Until the castor-transport container 14 rests on the bottom of the pool 12 at its first parking position 13 and the crane or the stopper aid 34 is relieved of its weight to be transported. In this way, it is possible that the vertical beams 42 can now be suspended from the Castor transport container 14 and the crane is available again for further tasks.
  • Fig. 2 shows in a three-dimensional view the crane hook 30 with attached stopper aid 34 and the castor transport container 14 attached thereto.
  • Fig. 2 shows the components already introduced in Fig. 1, so that in this figure also the corresponding reference numerals are used become.
  • the crane hook 30 has as an attachment element own double hooks 46, which surrounds the two bolts 36.
  • the scissors gear 44 has a number of hinges 48, which assemble a number of scissor rods 50 to the scissors gear 44.
  • the example chosen shows two diamond-shaped scissor elements which divide the hinges 48 and the scissors bars 50 into three vertical rows in this view. In a middle row while three joints 48 are arranged, wherein the upper joint 48 in this view is connected to a first connection element 52 and the lower row in the middle row 48 is connected to the horizontal beam 40.
  • the bolts 36 are part of the first connection element 52.
  • each tie rod 54, 56 is fixedly connected to the lower of the two joints 48, while these are each performed by the respective upper joints 48 only by a corresponding recess.
  • the tie rods 54, 56 have a length that is sufficiently dimensioned for the lifting task.
  • a drive 58, 60 associated with the tie rods 54, 56.
  • each drive nuts 62 are present, which are movable by the respective drive 60, 62.
  • the tie rods 54, 56 have corresponding threads which cooperate with the drive nuts 62.
  • the adjustable length is limited only by the geometry of the scissors gear 44 and by the length of the tie rods 54, 56. But it is also within the inventive idea that the desired change in length of the scissors gear is extended by the fact that more diamond-shaped joint / Scherenstangenan angelen be supplemented or the tie rods can be extended accordingly.
  • Figure 3 shows the same objects as Figure 2, which is why the same reference numerals are used in this figure.
  • An essential difference from Figure 2 is in this figure 3 that it shows the scissors gear 44 in a position which shows the maximum distance between the crane hook 30 and the horizontal beam 40.
