Definitions

  • the invention relates to a roller for soil compaction and a method for generating a vibration pattern of a roller for soil compaction.
  • rollers for soil compaction are used wherever compaction of the subsoil is desired over a relatively large area.
  • Such rollers for soil compaction include a machine frame with a control stand from which the roller is operated, a drive motor, usually a diesel engine, via which the drive energy required to operate the roller is made available, and at least one roller drum.
  • a roller bandage usually comprises an essentially hollow cylindrical bandage jacket as well as supplementary support elements, such as plate washers, etc.
  • the at least one roller bandage is usually rotatably mounted around a horizontal axis of rotation extending transversely to the forward direction between two bearing names arranged on the end face.
  • the bearing arms are at least partially rigid or, in the case of rollers pivoted, are connected to the machine frame via a pivot joint.
  • vibration exciters hereinafter also referred to as excitation unit, for generating vibrations within the at least one roller drum.
  • excitation unit for generating vibrations within the at least one roller drum.
  • the exciter unit comprises an exciter housing as well as two unbalance weights, which are mounted rotating in opposite directions within the exciter housing and coupled to one another. The coupling can take place, for example, via the engagement of two gears seated on the front side of the imbalance weights.
  • the imbalance weights can be rotated about two axes of rotation that are stationary relative to the exciter housing.
  • a drive motor arranged outside the exciter housing, usually a hydraulic motor, in drive connection with at least one of the two rotating unbalanced weights.
  • the drive motor or the drive connection can be designed in such a way that both imbalance weights are driven directly by the drive connection with the drive motor or there is a drive circuit in series, with one imbalance weight in drive connection with the drive motor driving the imbalance weight connected in series to rotate, for example via the face gears already mentioned.
  • the two imbalance weights are thus positively coupled.
  • the object of the invention is now to provide a roller for soil compaction which allows inexpensive manufacture with at the same time adequate and, in particular, subsurface-friendly vibration behavior.
  • the exciter housing is rotationally fixed with respect to the bearing arms, and that the two imbalance weights are coupled to one another in such a way that their amplitudes add up in the horizontal direction.
  • the usual and generally desired adjustability of the exciter unit relative to the machine frame is prevented by the non-rotatable connection of the exciter housing. This defines the relative position of the coupled unbalance weights with respect to the machine frame or at least with respect to the bearing arms (in the case of pivot-pivoted rollers), specifically in such a way that their amplitudes add up in the horizontal direction.
  • the imbalance weights thus rotate in mutually opposite directions around an axis of rotation in such a way that their amplitudes cancel each other out in the vertical direction and in the horizontal direction, in particular in and against the forward direction of the Roller, add up.
  • the rotational components in the vertical direction run in the same spatial direction. In total, an exclusively horizontal directional oscillator is thus obtained, which essentially exclusively generates horizontal oscillations.
  • the excitation unit is preferably designed in such a way that the two axes of rotation of the two imbalance weights run horizontally and transversely to the forward direction of the roller and one above the other in the vertical direction.
  • the two imbalance weights are thus positioned vertically one above the other and running parallel to one another, at least with regard to their axes of rotation. It is also advantageous if the two imbalance weights have the same imbalance masses and also mass distributions that are equal to one another with respect to their respective axis of rotation. As a result, the two imbalance weights can be designed to be essentially identical, whereby the manufacturing costs can be reduced again.
  • a rotation lock is preferably used which connects the exciter housing to at least one of the two bearing arms.
  • the rotation lock is ideally designed in such a way that it enables a rotary movement of the exciter housing with respect to the at least one of the two bearing arms, in particular via form-fitting elements.
  • the rotation lock is preferably designed in such a way that it effects a form fit on both sides of the direction of the circumferential movement of the bandage about its axis of rotation, in particular within, at the height or at least in the immediate axial proximity of the at least one bearing arm.
  • the anti-rotation device is preferably designed in the form of a stub shaft running through a drum pivot bearing, which is led out of the drum interior in particular on a drive end face of the end face opposite the at least one roller drum.
  • a drive face In the present case, such an end face of the roller drum is referred to, via which the drive of the exciter unit is achieved.
  • a suitable hydraulic motor is preferably arranged on the front side of the roller drum, in particular at the level of the axis of rotation of the roller drum or coaxially with it, on a bearing arm. In this context, it is not about the drive of the roller drum, which is often achieved by drive drives, in particular hydraulic motors, attached on both sides of the roller drum.
  • the stub shaft is thus arranged on the side of the drum opposite the drive motor of the excitation unit. This facilitates the positioning in particular of the drive motor for the excitation unit.
  • the stub shaft is arranged between two flange plates, one flange plate being fixed to the exciter housing and the other flange plate being fixed to the bearing arm, in particular being directly flanged to this.
  • the flange plates With the help of the flange plates, a sufficiently resilient connection of the stub shaft to the exciter housing and to the bearing arm is achieved.
  • the stub shaft furthermore preferably comprises a circumferential toothing which is attached at least at the end, ideally on both sides, and which is arranged in a corresponding complementary hollow toothing, for example on one or both of the two flange plates.
  • a circumferential toothing which is attached at least at the end, ideally on both sides, and which is arranged in a corresponding complementary hollow toothing, for example on one or both of the two flange plates.
  • the stub shaft is also preferably designed to be mirror-symmetrical in order to facilitate assembly.
  • the bearing arms are preferably designed in such a way that they include a damping stage at least between an outer part and an inner part, the exciter housing then being connected to the inner part via a rotation lock, in particular directly is rotatably connected.
  • a damping stage can for example be one or more rubber buffers arranged in parallel or the like.
  • the outer part of the bearing arm includes that part which is directed towards the machine frame and, in the case of articulated rollers, is ideally rigidly connected to the latter and, in the case of rollers with pivot point steering, is at least indirectly connected to the pivot point joint.
  • the inner part of the respective bearing arm denotes that part that is arranged behind the damping stage, coming from the machine frame, and on which the exciter housing is at least indirectly supported. It is particularly preferred if the aforementioned flange plate is flanged, in particular screwed, directly to the inner part of the respective bearing arm.
  • Another essential advantage of the invention is that the design and arrangement of the excitation unit according to the invention enables operation with a so-called split roller drum with two roller drum halves without any problems and in particular without additional adaptation measures.
  • Split roller drums are known and customary in the prior art. For this purpose, however, in particular in connection with excitation units, comparatively complex synchronization mechanisms for the two halves of the roller drum have to be used. This does not play a role in the present arrangement, so that robust and reliable operation is also possible with a split roller drum.
  • This has the advantage that, with regard to the design and mounting of the exciter unit, one and the same basic arrangement for undivided and divided roller drums can be used.
  • the exciter unit extends in the axial direction of the axis of rotation of the at least one roller drum into both halves of the roller drum, particularly preferably in the axial direction of the axis of rotation in equal parts with respect to the two unbalance weights. In this way, a relatively homogeneous distribution of the vibration effect of the exciter unit is achieved on both roller drum halves.
  • the two roll drum halves have the same extension in the axial direction of the axis of rotation of the at least one roll drum. In other words, the hollow cylinder-shaped drum jackets of the two roller drum halves have the same cylinder height.
  • the split roller drum with two roller drum halves for generating vibrations exclusively comprises the one exciter unit with two unbalance weights. This also simplifies the structure of the entire roller drum.
  • the roller has a further roller drum and is in particular an articulated or rotary mold-steered tandem roller.
  • Such rollers are known in terms of their basic structure in the prior art and are particularly well suited for the arrangement described above.
  • the further roller drum comprises a further exciter unit in order to improve the compaction process here too with the aid of vibrations generated by the exciter unit.
  • the further exciter unit is particularly preferably designed in such a way that it generates a vibration characteristic that is different from the exciter unit described above, in which the amplitudes of the two imbalance weights add in the horizontal direction and cancel in the vertical direction, with such an exciter unit being particularly preferred here, which at least temporarily generates a vertical component during work.
  • This enables a combination of the horizontal directional oscillator, as described above, with one Excitation unit that at least partially introduces vibrations with vertical components into the ground. This combination enables a particularly advantageous compression result to be obtained.
  • the further excitation unit is a so-called circular exciter.
  • a circular exciter is characterized in that it has only a single unbalanced mass rotating about an axis of rotation, ideally with an axis of rotation running horizontally and transversely to the forward direction.
  • Such circular exciters are also known in principle in the prior art and are characterized in particular by their simple structure and their high robustness.
  • a coordination device which coordinates the operation of the two excitation units with respect to one another, in particular with regard to their frequency and / or phase position.
  • the correlation device can have suitable sensors, in particular rotation sensors, for example on the respective drive motors, as well as a control unit which controls the operation of at least one of the two drive motors of the two excitation units and in this way enables suitable coordinated operation.
  • Another aspect of the invention also lies in a method for generating a vibration pattern with a roller according to the invention for soil compaction, in particular a vibration pattern suitable for compaction that is gentle on the subsoil.
  • the vibration pattern denotes the overall vibration behavior of the two roller drums with respect to the ground or, ultimately, the sum of the two exciter units combined with one another in the method according to the invention, consisting of a horizontal directional oscillator and a further, in particular different, exciter unit.
  • the method is particularly suitable for use on a tandem roller.
  • steps A) generating an exclusively horizontal oscillation or an oscillation with exclusively horizontal amplitude, in a first drum, in particular with the aid of the horizontal directional oscillator described above, and B) generating a different vibration, in particular with a vertical component, in a second bandage, take place simultaneously.
  • the generation of a different type of vibration with a vertical component thus denotes such a vibration characteristic in which, at least temporarily, an at least partially vertically acting compression force is also introduced into the subsoil.
  • the machine provides a kind of oscillating vibration behavior, in which the sum of the two bandages, at least at times, obliquely acting compaction forces are introduced into the ground. This can be required by users for certain compression tasks.
  • the exclusively horizontal oscillation for a specially divided roller drum with two roller drum halves, as described above for the roller according to the invention is generated exclusively via a single exciter unit, specifically the horizontal directional vibrator described above.
  • This method is distinguished by the fact that it provides a simple and reliable option for generating horizontal vibrations for a divided roller drum, even for a split drum.
  • FIGS. 1, 2 and 3 first illustrate the basic structure of various generic rollers 1.
  • Essential elements of this roller 1 are a machine frame 2, a control stand 3, a drive motor 4, as well as only a front and a rear roller bandage 5.
  • the roller bandages 5 can be rotated via two lateral bearing arms 6 about a horizontal axis of rotation running transversely to the forward direction A. mounted on the bearing arms 6, only the left bearing arm 6 facing the viewer being visible in FIGS. 1 to 3.
  • the roller bandages 5 can be steered about a substantially vertical steering axis relative to the machine frame 2 via a pivot joint 7.
  • a hydraulic motor is provided in each case to drive the roller drums 5 (not shown in the figures).
  • Figure 2 shows in contrast to Figure 1 an articulated tandem roller.
  • the machine frame 2 comprises two frame halves (front and rear frame halves) which are connected to one another via an articulated joint 8.
  • the bearing arms 6 are rigidly connected to the machine frame 2 at least with their part facing the latter.
  • Figure 3 finally shows a roller 1 of the roller train type.
  • the machine frame 2 comprises two frame halves, the front section and the rear section, which are connected to one another via a knee joint 8.
  • the roller train comprises only a single roller drum 5 and a pair of rear wheels 9. All of the rollers 1 of the Figures 1 to 3 are self-propelled and include an excitation unit in at least one of their existing roller drums 5, as explained in more detail in the following figures.
  • Figure 4 To further explain the structure of at least one of the roller bandages 5 of the rollers 1 from the Figures 1 to 3 is initially on Figure 4 Referenced.
  • This relates to a vertical longitudinal section along the axis of rotation D in a slightly oblique perspective view.
  • Essential elements of the roller drum 5 are a hollow cylindrical drum jacket 10 with two drum jacket halves 10A and 10B.
  • Figure 4 thus shows a two-part roller drum 5, the design and mounting of the exciter unit described further below being equally usable for undivided roller drums.
  • the axes of rotation R1 and R2 run parallel to one another and also parallel to the axis of rotation D and one above the other in the vertical direction.
  • a drive motor 22 is provided, in the present case a hydraulic motor.
  • the roller drum 5 thus exclusively comprises the one excitation unit 13.
  • the exciter housing 14 comprises on both sides along the axis of rotation D an end plate 17, 18 and a housing cylinder 19 spanning the imbalance weights in the direction of their axis of rotation R1 and R2 between the end plates 17 and 18, which in the present exemplary embodiment is not completely closed.
  • the mounting of the exciter unit 13 is in relation to the bearing arms 6, which in FIG Figure 4 are only partially shown, non-rotatable. This means that the bandage jacket 10 can be rotated with respect to the exciter unit 13, for example by means of pivot bearings 20, but is essentially stationary and non-rotatably mounted with respect to the bearing arms 6.
  • the bearing arms 6 each comprise an outer part 6A and an inner part 6B, which are connected to one another via damping elements 21 in order to transmit vibrations generated by the exciter unit 13 during operation to the machine frame 2, with which the outer part 6A of the bearing arms in the to the Figures 1 to 3 described way is connected to minimize.
  • a rotation lock 25 with a plug-in shaft 26 is provided on the end face 24 of the roller drum 5 opposite the end face 23 of the roller drum 5, on which the drive motor 22 for driving the excitation unit 13 is arranged, or on its side.
  • One end of the plug-in shaft 26 is non-rotatably inserted in a flange plate 27 which is flanged to the end plate 17 of the exciter housing 14.
  • the stub shaft 26 runs coaxially to the axis of rotation D through a rotary bearing of the roller drum 5 on the bearing arm 6 and ends in a rotationally fixed manner in a flange plate 28 which is flanged to the inner part 6B of the bearing arm 6 from the outside.
  • the stub shaft has form-locking elements to prevent rotation in at least that axle shaft area with which it opens into one of the two flange plates 27, 28, in particular those with stop surfaces acting in the direction of rotation of the axis of rotation D, such as circumferential external teeth.
  • form-locking elements are in engagement with complementary form-locking elements in the respective flange plates 27, 28, for which purpose, for example, internal toothing that is complementary to the external toothing of the stub shaft can be used.
  • a friction fit for example by means of suitable knurling, in particular on the stub shaft, etc.
  • the exciter unit 13 On the end face 23 opposite the anti-rotation device 25, the exciter unit 13 is in drive connection with the drive motor 22 via a shaft.
  • the shaft is connected to one of the imbalance weights 15A, 15B via a gear connection.
  • the other imbalance weight is driven via the gear pair 16 attached to the imbalance weights 15A and 15B and meshing with one another.
  • the imbalance weights 15A and 15B are arranged in the exciter unit 15 in such a way that their amplitudes add up in the horizontal direction in the rotational operation about the rotational axes R1 and R2 and cancel out in the vertical direction. If the excitation unit 13 in the roller drum 5 according to Figure 4 thus put into operation, the roller drum 5 and in particular its two roller drum halves 10A and 10B are subjected to horizontally aligned vibrations. Specifically, this is achieved in that the imbalance weights with their imbalance lying outside in the radial direction in relation to the axis of rotation R1 and R2 rotate in opposite directions from above and below and each rotate in the same spatial direction in the horizontal direction. Overall, with this arrangement, a horizontal directional vibrator with an exclusively horizontal overall amplitude is thus obtained.
  • Figure 5 gives the in Figure 4 The basic structure described in a schematic diagram in a slightly modified form again, with the description of the Figure 5 especially to those already too Figure 4 Reference is made to the statements made. It is essential that especially in Figure 5 It is clearly shown that in the direction of the axis of rotation D on both sides of the excitation unit 13 there is in each case a plug-in shaft 26 for rotation lock with the corresponding flange plates 27 and 28. Also clarified Figure 5 the connection of the bearing arms 6 to the machine frame 2 via their outer part 6A in each case, whereby a turntable joint can alternatively also be interposed here, as already mentioned above. The roller drum halves 10A and 10B can be rotated about the axis of rotation D with respect to the bearing arms 6B via a swivel joint, not shown in detail.
  • Figure 6 accesses the basic structure of the Figures 1 to 3 rollers 1 shown and illustrates a further development in that two different excitation units are provided in the exclusively two roller drums 5 comprised by the roller.
  • left roller drum 5 is the excitation unit 13, as in the Figures 4 or 5 explained in more detail, arranged in the form of the horizontal directional vibrator, with only the two unbalance weights 15A and 15B and their rotational movement in a vertical plane transverse to the axis of rotation D of the two roller drums 5 being shown for simplification.
  • the right-hand roller drum 5 comprises an exciter unit 31 which acts differently than the exclusively horizontal directional oscillator and which, in the specific exemplary embodiment, is a circular exciter with only one imbalance weight 15.
  • the oscillation characteristic of this circular exciter is that it generates a phase-dependent oscillation spectrum with oscillation components that act vertically upwards and downwards and horizontally forwards and backwards, as in Fig. 6 indicated cross arrow clarified.
  • This excitation unit 31 is arranged in the front roller drum 5 of the roller 1 in the forward direction A. In the sum of the two excitation units 13 and 31, an oscillation characteristic with the roller 1 is thus obtained Figure 6 obtained, in which at least transient oblique forces can be introduced into the substrate.
  • the directional oscillator 31 can also be substituted by exciter units that act differently, such as an oscillation exciter, an adjustable directional oscillator, etc.

  • FIG. 7 finally shows a flow chart of a method according to the invention. It is essential that when a roller is operated 33 an exclusively horizontal vibration is generated in a first drum according to step 34 and a different vibration, in particular with a vertical component, is simultaneously generated in a second drum according to step 35.
