Definitions

  • the invention relates to an installation for compacting concrete mix, comprising a frame which has a lower plate and an upper plate between which concrete mix can be accommodated, which plates can be pressed in the direction towards one another and can be made to vibrate with respect to one another in order to compact the mix.
  • Said known installation has the disadvantage that the noise level and vibrational level in operation are unacceptably high. Consequently, said installation constitutes an unacceptable burden on the surroundings, whilst it is also not able to meet legal requirements with regard to working conditions. Moreover, the environmental nuisance, caused by noise and vibrations, is too high.
  • the aim of the invention is, therefore, to provide an installation of the type described above which does not have these disadvantages. This is achieved because each plate is connected to the frame by means of an associated, spring-mounted massive body.
  • the relatively large massive bodies prevent vibrations being transmitted to the frame.
  • An additional advantage of said bodies is that a substantial machine foundation is no longer required since said foundation only has to take the weight of the installation but does not have to absorb the dynamic forces which are associated with the vibrating function of the installation.
  • the upper plate is connected to the associated upper massive body by means of an exciter, whereas the lower plate is connected to the associated lower massive body by means of a pressure cylinder.
  • the frame is so constructed that the latter has, on the one side, a set of anchor points for the upper massive body and, on the other side, a set of anchor points for the lower massive body, and at least the frame sections which connect the sets of anchor points are rigid.
  • the frame comprises two parallel plate sections, each of which has a vertical section which connects two horizontal sections, which horizontal sections carry the anchor points.
  • Figure 1 is a schematic diagram of the installation according to the invention.
  • Figures 2 a and 2 b show, respectively, a front and a side view of an embodiment of the installation according to the invention.
  • 1 and 2 indicate frame sections on which the upper massive body 4 is mounted by means of springs 3 and the lower massive body 6 is mounted by means of springs 5.
  • the upper massive body carries a hydraulic exciter 7, an upper plate 9 being fixed to the piston rod 8 thereof.
  • the lower massive body carries a pressure cylinder 10, the lower vibrating plate 12 being fixed to the piston rod 11 thereof.
  • Both the exciter 7 and the pressure cylinder 10 can be operated by means of the hydraulic unit 13.
  • the hydraulic unit 13 is controlled by means of the control and regulator unit 14.
  • compaction of the product 15, which is located between the upper plate 9 and the lower plate 12 is effected by a combination of excitation and compression.
  • the vibrations are generated by means of the hydraulic system 13, 14.
  • the hydraulic system 13, 14 also provides the compression function.
  • the vibrating components of the installation in particular the vibrating plates 9, 12, exciter 7 and pressure cylinder 10, can develop severe vibration, which vibrations are transmitted to the upper massive body 4 and the lower massive body 6.
  • Said massive bodies 4, 6 have such a high mass that the violent vibrations of the components 7, 9, 12 and 10 are not able to be transmitted directly to the frame 1, 2.
  • the spring mountings 3, 5 also form a supplementary barrier against transmission of vibrations to the frame 1, 2.
  • the compaction installation shown in Figures 2 a and 2 b makes use of the construction principle shown in Figure 1.
  • This installation comprises a very rigid frame 16, which constitutes a closed system and contains two C-shaped walls 17, 18.
  • Support plates 19, 20 are fitted on the horizontal arms of the walls, which support plates are firmly fixed to the walls 17 by means of support strips 21 and 23.
  • the spring mountings 24 for the upper massive body 25 and, respectively, the spring mountings 26 for the lower massive body 27 are fitted on said support plates 19, 20.
  • the lower massive body 27 has a recess 28, in which the hydraulic press 29 is incorporated.
  • the exciter 30 is suspended from the upper massive body 25.
  • the massive bodies are provided with, respectively, a lower vibrating plate 31 and an upper vibrating plate 32.
