Definitions

  • the invention relates to a vibrating device with oscillating, spaced modules with two parallel, counter-rotating unbalance shafts with unbalances, the modules being arranged one behind the other in the longitudinal direction to the unbalanced shafts and adjacent modules being coupled via shafts attached to the successively arranged unbalanced shafts , - A vibrating device with oscillating, spaced modules with two parallel, counter-rotating unbalance shafts with unbalance, whereby on different modules, one behind the other unbalanced shafts of the same direction of rotation are coupled via shafts attached to the successively arranged unbalanced shafts, and - a vibrating device with vibrating, mechanically coupled modules and with parallel arranged, counter-rotating unbalance shafts with unbalance.
  • Such a vibrating device is known from DE-AS 25 47 762.
  • the vibrating device has adjacent modules, each of which includes two parallel shafts with unbalance.
  • the unbalanced shafts lying one behind the other in the longitudinal direction are coupled to one another by shafts.
  • the modules each have a wall element to be shaken (arranged vertically).
  • Each wall element is inserted by means of elastic seals in windows of a fixed shape, which is intended for filling concrete.
  • DE-A-3 112 198 discloses a vibrating device with an elongated shape, which is fastened to a plurality of support elements which are mounted so that they can vibrate, each with two modules.
  • the modules each have an unbalanced shaft, the unbalanced shafts of the two modules of a support element being aligned in parallel.
  • the two modules are attached to a common connecting element, which extends perpendicular to the position of the unbalanced shafts.
  • the invention has for its object to provide a large-area vibrator, which is composed of small and light modules, with no stability problems and a particularly good distribution of the material to be vibrated can be achieved.
  • the counter-rotating rotation of the unbalanced shafts arranged in parallel ensures a directional swinging movement - perpendicular to the surface formed by the unbalanced shafts.
  • the unbalanced shafts can be components of unbalanced motors that are switched on during operation. It is also conceivable for the unbalanced shafts to be driven by a single motor or by a plurality of oscillating or stationary motors.
  • the container can be, for example, a shape, e.g. B. for a component made of concrete. If several modules are arranged next to one another, the immediately adjacent unbalanced shafts attached to different modules can be brought into a rotational movement in the same direction by means of a belt or a toothed belt.
  • the shafts that connect unbalanced shafts arranged one behind the other can be cardan shafts or shafts that have a coupling on at least one end.
  • the couplings on the shaft ends can compensate for an offset or deflection.
  • the couplings should not be flexible in the direction of rotation, but they should be in the axial direction. In the event of an offset in the (unbalance) shafts arranged one behind the other or in the event of deflections, proper operation is possible.
  • a large-area vibrating table can be formed by designing the carrier elements as flat surfaces, which are all at the same height.
  • Such a vibrating table can be expanded as required (subsequently) by coupling modules of the same design, without the need for a new dimensioning or reinforcement of the modules already installed.
  • the gaps between the surfaces of the carrier elements can be closed by elastic seals. It is also conceivable that adjacent surfaces overlap. These measures prevent smaller parts from falling through the interstices of the individual surfaces or getting caught between them.
  • the vibrating table serves as a vibrating base for a freely movable (“dancing") shape thereon; A viscous mass introduced into the mold is then compressed particularly evenly, because the compression effect is particularly effective at the frequencies and amplitudes that occur. So that the shape does not fall laterally from the vibrating table, the vibrating table surface could be laterally surrounded by an edge. It is possible to dimension the modules in such a way that they can only oscillate up to a load limit with regard to the loaded weight and are unyielding when the load limit is exceeded.
  • the load limit could then be set so that it is reached when an industrial truck drives onto the vibrating table surface. It is possible to support the individual modules of the vibrating table on air springs.
  • the connecting element which runs perpendicular to the elongated support elements of the vibrating device with exactly two modules (each with a single unbalanced shaft) and is connected to the support elements, can be, for example, a double-T support that is always rigid along its longitudinal direction and is slightly torsionally flexible .
  • magnetic vibrators can also be used as drives for generating vibrations instead of the unbalance motors.
  • the container with the goods to be shaken - for example a mold - is fastened to the carrier elements with fastening elements and is therefore not freely movable, the noise during operation is significantly reduced, which leads to considerable cost savings in production because of complex noise-reducing construction measures can be dispensed with. It is also advantageous that the operating personnel is exposed to lower levels of health hazards due to the noise reduction.
  • clamping devices are particularly cheap, especially when the container to be clamped has a shape, for example for railway sleepers are made of concrete. Molds filled with concrete can then be quickly clamped onto the vibrating device one after the other to produce a larger number of railway sleepers.
  • the tensioning element could have a hydraulic cylinder with a piston with an arm pointing outward in the longitudinal direction of the hydraulic cylinder, the length of the tensioning element being hydraulically variable by moving the arm.
  • the clamping member could be dimensioned so that it is in the container for the material to be shaken in the.
  • Each module 1 shows a side view of a vibrating device with three modules 1.
  • Each module 1 has two unbalance motors 2, the unbalanced shafts of which are aligned parallel to one another.
  • the unbalanced shafts protrude with their two ends beyond the stand of the unbalance motors 2.
  • At these ends of the unbalanced shafts there are unbalances which each rotate within a housing 5.
  • the unbalance shaft with the unbalance at both ends of the left unbalance motor 2 is indicated by dashed lines.
  • the aligned unbalanced shafts arranged one behind the other are coupled by shafts 7, which are connected to the unbalanced shafts via couplings 9.
  • Elongated support elements 6 are mounted on the unbalance motors 2 and extend into the plane of the drawing.
  • a tensioning device 11 is attached to both ends of the elongated support elements.
  • the clamping devices 11 hold a mold 10 which has a high material rigidity.
  • the shape 10 runs through the entire vibrating device and gives it 6 stability by fastening to the carrier elements.
  • Any number of modules 1 can be arranged one behind the other; as an example, a third module 1 is drawn in dashed lines.
  • Fig. 2 shows the vibrating device according to Fig. 1 in the bottom view.
  • Two parallel rows of unbalance motors 2 coupled one behind the other by shafts 7 can clearly be seen.
  • the unbalance shafts of the unbalance motors 2 in the opposite rows rotate in opposite directions. Any number of additional modules 1 can be connected. Overall, however, the vibrating device should not be longer than the shape 10 to be clamped.
  • Fig. 3 shows a large-area vibrating device, which is composed of partial table surfaces I, II, ... XV.
  • the vibrating device has a total of more than just two rows of unbalance motors M1 ... M16.
  • Each subtable surface I ... XV forms a module with two unbalance motors rotating in opposite directions.
  • Imbalance motors M1 ... M16 arranged one behind the other in the longitudinal direction are connected to one another via couplings and shafts.
  • On two adjacent subtable surfaces I ... WV rows of unbalance motors arranged side by side are positively synchronized via a toothed belt Z (or a chain).
  • the toothed belt Z is attached to the associated toothed belt pulleys of the motors M14 and M15, M16 and M29 at the end of the rows with the unbalance motors M2, M6, M10, M14 and M3, M7, M11, M15 and M4, M8, M12, M16.
  • the unbalance of the rows of unbalance motors M1 ... M16 connected by the toothed belt Z should always be aligned in the same direction during assembly, for example, all in an alignment downwards or to the right. In this way, the tensile stresses acting on the toothed belt Z are kept low.
  • FIG. 4 shows a side view of the vibrating device according to FIG. 3, specifically with a view of the toothed belt Z.
  • the directions of rotation of the unbalance motors M1 ... M16 arranged in rows one behind the other can be seen.
  • the unbalance motors, which are attached to a single module, run in opposite directions.
  • the unbalance motors M14, M15 and M16, M29 connected by the toothed belts Z are fastened under adjacent subtable surfaces and rotate in the same direction.
  • a further embodiment of a vibrating device can be seen in the bottom view in FIG. 5.
  • Each of the two unbalance motors 2 is fastened from below to an elongated support element 6 '.
  • the unbalance motors 2 are arranged parallel to one another, specifically the motor shafts (with unbalances attached to them) lie parallel to the elongated support elements 6 '.
  • the motor shafts with the unbalance rotate in opposite directions, so that a swinging movement occurs perpendicular to the plane of the drawing.
  • the support elements 6 'each have a tensioning device 11 at their ends. All four clamping devices 11 together hold a shape 10 'that of the Clamping devices 11 is pressed from above against the carrier elements 6 '.
  • the connecting element 12 is designed to be rigid and torsionally elastic along its central axis, which runs centrally between the outer edges of the clamped vibrating element, ie it does not bend, but is easily rotatable about its central axis (torsion). This enables a directional oscillating movement, even if the shape 10 'is not distinguished by a high level of material rigidity.
  • the mold 10 ' can be clamped well even if its underside has slight unevenness.
  • the mold 10 ' is held by clamping elements 11 which are attached to the ends of the two support elements 6'.
  • the shape 10 ' gives the vibrating device additional material rigidity.
  • Fig. 6 shows a clamping device 11 which works hydraulically.
  • a clamping member 13 arranged perpendicularly - parallel to the side wall of the mold 10 '- has a hydraulic cylinder 14 in which a piston 15 can be moved up and down by the action of hydraulic oil flowing in or out.
  • the piston 15 is connected to an arm 16 which projects out of the hydraulic cylinder 14 along the central axis thereof.
  • This arm 16 transmits its upward and downward movement to a rotatably mounted lever 17 which is fastened to the arm 16 via a swivel joint 18. Laterally offset from the rotary joint 18, the lever 17 has a further joint 19, as a result of which the lever 17 is divided into two lever arms.
  • the lever arm 20 facing away from the hydraulic cylinder presses on the mold 10 'from above when the tensioning member 13 has its maximum length.
  • the tensioning member 13 has a further swivel joint 21, which moves a second lever 22.
  • This lever 22 is movable about a pivot joint 23 which is laterally offset with respect to the tensioning element 13.
  • the possible directions of rotation of all swivel joints 18, 19, 21 and 23 lie in the same plane.
  • the lever arm 24 of the lever 22 facing away from the tensioning element 13 is supported at its end downward with a clamped shape 10 'on a projection 25 which is arranged below on the side of the lever arm 24 facing away from the carrier element 6' and at the same time is fastened below the carrier element 6 ' .
  • a further swivel joint 26 is located between the swivel joint 23 of the lever 22 and the end of the lever 22 supported on the projection 25 available, on which - in the plane of the directions of rotation of all rotary joints 18, 19, 21, 23 and 26 - two angle pieces 27 are attached symmetrically left and right to the longitudinal direction of the lever arm 24, which on the sides facing away from the lever arm 24 parallel to the underside of the Carrier element 6 'create two levels, on each of which a coil spring 28 is supported.
  • the spiral springs 28 are fastened to the underside of the carrier element 6 'and, when the shape 10' is clamped in, press against the underside of the carrier element 6 '.
  • FIG. 8 illustrates the directions of movement in the case of tensioning the tensioning device 11. The parts shown in the latter two figures are explained in connection with the description of FIG. 6.
  • Fig. 9 shows a clamping device 11 ', which is slightly modified compared to that of FIGS. 6 to 8.
  • the upper half of the figure corresponds to the representation in FIG. 6, this applies in particular to the hydraulically displaceable clamping member 13 and the mechanism with the upper lever 17, which, when the mold 10 ′ is clamped in, has its lever arm 20 on the mold 10 from above 'presses.
  • Parts of the same design are given the same reference numerals in FIGS. 6, 7, 8 and 9.
  • two angled holding elements 29 are attached symmetrically laterally to the left and right to the longitudinal direction of the lever 22 ', as in FIG. 6, each supporting a coil spring 28'; the coil springs 28 ' are each attached with their other end to the underside of the carrier element 6 '.
  • two further spiral springs 30 are arranged below the angled holding elements 29, each of which is fastened with one end below the holding element 29 and with its other end on a shoulder 31 which is fixed relative to the carrier element 6'. All spiral springs 28 ' , 30 need not be prestressed when the mold 10 'is clamped. When the clamping member 13 is shortened to take out the mold 10 ', the lever arm 20 rotates away from the mold 10'.
  • the tensioning member 13 is pressed downward and with it the lever 22 ′ fastened at the bottom to the tensioning member 13 via the swivel joint 21.
