Definitions

  • the at least one resilient element can generate lower forces in the degressive characteristic area than in the progressive characteristic area. Then the degressive characteristic curve lies in the coordinate tensystem to the left of the first characteristic area and the progressive characteristic area to the right.
  • the actuating element and the (or the first and / or the second) holding region are connected to each other in such a way that a spring-elastic element arranged therebetween is kept biased.
  • the device according to the invention comprises a coupling element (eg in the form of an arm).
  • the coupling element can be designed to introduce forces that bias the at least one resilient element.
  • the first abutment portion 30 and the first holding portion 32 are movable relative to each other. Movements of the first holding portion 32 to the first abutment portion 30 to (here, holding plate 32 is moved in the direction of arrow 40) load (compress) the first resilient elements 26. Movements of the first holding portion 32 of the first abutment portion 30 away (here, retaining plate 32nd is moved opposite to the direction of arrow 40) relieve the first resilient elements 26.
  • the element 20 coupled to the guide device 16 via the coupling element 18 is connected to the first and second holding regions 32 and 36, respectively, by means of a first cap 38 and a second cap (not shown) of comparable design.
  • the guide device 16 can be moved upward in relation to the support structure 24 or components connected thereto, as shown.
  • the element 20 and the associated second cap and second holding portion 36 are moved upward.
  • This biasing force can be used to reinforce forces provided by the exciter modules 4 that are provided in total opposite to the direction of action 40. Such preload forces can be particularly advantageous if it is to be removed from the ground by means of the vibration exciter piles.
  • the upper and lower exciter modules 4 are arranged so that their shafts 46 extend parallel to one another in a plane 48 which runs parallel to a direction of action 40.
  • the shaft 50 of the middle exciter module 4 is likewise arranged parallel to the shafts 46, but is not located in the plane 48.
  • the arm 52 is connected by means of one or more first elastic elements 26 and by means of one or more second elastic elements 28 with a guide means 16.
  • the elastic elements 26 and 28 represent components of a device according to the invention with first and second th units comprising the resilient elements 26 and 28, respectively.
  • Such a force-displacement characteristic can be achieved by the springs, for example, consist of cellular elastomer or to such an extent that the resulting force-displacement curve is of the type shown in Fig. 3.
  • the springs for example, consist of cellular elastomer or to such an extent that the resulting force-displacement curve is of the type shown in Fig. 3.
  • the spring-elastic components / materials with linear force-displacement characteristic and those with a force-displacement characteristic of the type of Fig. 3 include. This can e.g. be achieved by a combination of coil spring and Elastomerfederan negligence.
  • the spring-elastic elements 26 and / or the resilient elements 28 are statically prestressed or deformed in such a way that resulting spring forces result from the preloaded installation, which results from the left-hand beginning of the almost linear one in FIG Area Bl is located. Further deformation (compression) then leads to spring forces or spring travel in accordance with the approximately linearly running region B1.
  • the maximum spring force F max indicates the maximum spring force or the maximum spring travel x max at which the device 22 operates in (nearly) linear characteristic range Bl. However, with the device 22, higher forces or larger spring travel can be realized; then the device 22 operates in the progressive characteristic region 83. This may for example be the case when the device 22 is acted upon by the guide means 16 with a force greater than F max ; This can also occur when the device 22 by resulting
  • the device 22 furthermore has spring-elastic properties which now follow the characteristic region B3. Accordingly, a comparison is obtained with respect to the characteristic curve B3. range Bl - progressive stiff spring characteristic with less travel or vice versa.
