  • the known base course paver leads to considerable acquisition or maintenance costs of a construction equipment which cannot be used in any other way, which additionally has to be transported to the respective construction site whenever a base course is to be manufactured and then has to be removed from this construction site again.
  • the object is achieved by the combination of an excavator with a vibrating device specified in claim 1.
  • the excavator arm already provided on the excavator can be used on the one hand to move the vibrator from a storage position, e.g. B. on a truck or on the edge of the site to lift and attach to the holding device.
  • the excavator arm with the excavator shovel provided on the excavator arm can be used for the z. B. on a truck brought material from the truck and distribute it on the ground in front of the excavator and in front of the vibrator.
  • An additional excavator which would have to carry out this unloading and distribution, and would have to drive on the not yet compacted surface in front of the vibrating device, is therefore not necessary. This is particularly advantageous because the impressions produced by the tires of the additional excavator in the prepared but not yet compacted subsurface make it extremely difficult to produce a flat, uniformly compacted base layer.
  • the excavator itself has a very high weight (up to 25 t), it is ensured that the vibrating device rests with a very high pressure on the material to be vibrated, so that a good coupling for transmitting the vibrations generated by the vibrating device from the vibrating device on the material to be compressed is ensured.
  • the vibrating device has a mounting base which can be hooked onto the holding device with hook sections. It is thus possible for the excavator driver to lift the vibrating device with the excavator arm from the ground automatically and without additional help and by hooking the hook portions to the holder on the excavator, thereby reducing the time required for a vibrator to provide a base course.

All elements required for articulating the vibrating device on the excavator are thus firmly connected to the excavator, so that a particularly stable articulation of the vibrating device on the excavator can be provided. Furthermore, only the vibrator itself is removed from the excavator for transportation, so that the separate transportation of the excavator and the vibrator is also facilitated.
  • Swivel arm include, as well as an upper swivel arm pivotally attached to an upper portion of the support plates and to an upper portion of the support plates, which is arranged essentially parallel to the lower swivel arm and forms with this a parallelogram guide for the vibrating device carrier.
  • the parallelogram guidance of the vibrating device carrier and thus the vibrating device ensures that when the vibrating device is raised or lowered it is not pivoted relative to the excavator and thus relative to the ground and thus rests with its entire working surface on the ground at any working height.

  • the length of the vibrating device carrier in the transverse direction of the undercarriage is less than or equal to the maximum width of the undercarriage, it is ensured that there are no components which protrude laterally over the undercarriage so that the undercarriage can be transported or moved on public roads without any problems can be.
  • coupling elements are provided in the region of the outer ends of the vibrating device carrier in the transverse direction of the undercarriage for firmly coupling the vibrating device carrier to the vibrating device.
  • the articulation of the vibrating device on the vibrating device carrier is thus provided as close as possible in the region of the lateral ends of the vibrating device, so that the torques transmitted by the vibrating device to the vibrating device carrier and the holding device are kept as low as possible.
  • the holding device can comprise swivel devices which are respectively attached to side surfaces of the chassis frame of the chassis and which can be firmly coupled to the vibrating device.
  • the coupling of the vibrator with the excavator is on the side of the undercarriage, i.e. outside of the crawler tracks, enables a strong reduction in the torques transmitted from the vibrating device to the undercarriage, in particular around an axis of rotation parallel to the direction of travel, whereby a particularly stable coupling of the vibrating device to the excavator is provided.
  • the swivel devices each have vertically spaced upper and lower swivel arms which are articulated on the chassis frame with one of their ends and which can be firmly coupled in the area of their other ends to the vibrating device in order to provide respective parallelogram guides for the vibrating device.

  • Conventional excavators are generally unable to operate in a low speed, i.e. to drive in a range of 1 to 3 m / min. at such a uniform speed as is desired for the production of base layers.
  • the reason is that conventional excavators are designed for higher driving speeds of, for example, more than 3 km / h (50 m / min.).
  • the oil pumps provided for operating the traction motors are adjustable in terms of their delivery rate, but cannot deliver a uniform amount of oil in the area of low delivery rate, since they then already work in the area of the leakage oil flow.
  • the hydraulic pump is a triple pump, a pump part serving to actuate the first and second cylinder units, a pump part serving to drive the at least one vibrator, and a pump part serving to drive the undercarriage. It is thus possible, by appropriate design of the drive pump part for low pumping power, using the motor provided in any case on the excavator, to supply a pump oil quantity suitable for driving the vehicle at a very low and constant speed.
  • the cylinder units and the at least one vibrator can be operated by the same hydraulic pump, so that no additional units are required for this either.

B. by inserting intermediate elements, the strap carrier 218 can be attached in a position corresponding to the pairs of straps 204, 206 or 208, 210 on the vibrating device.
  • the embodiment of the holding device 152 described with reference to FIGS. 5 and 6 has the advantage that there are no components protruding beyond the upper edge of the undercarriage 150.
  • the freedom of movement or rotation of an uppercarriage arranged on the undercarriage is not restricted, and the superstructure can e.g. B. can be pivoted through 180 ° to the rear so that work can also be carried out in the area behind the excavator with the excavator.
  • the bearing points of the vibrating device carrier on the undercarriage are shifted as far out as possible, i.e.
  • FIG. 7 shows a plan view of a front section of a right crawler track chassis 240, an upper part of the crawler belt 242 being partially broken away.
  • the crawler track chassis 240 runs on a chassis frame 244 which is firmly connected to the undercarriage of the excavator.
  • a reinforcing plate 248 On an outer side surface 246 of the chassis frame 244, a reinforcing plate 248 z. B. firmly attached by welding.
  • a mounting plate 252 is removably fixed by a plurality of bolts 250.
  • an upper swivel arm 254 and a lower swivel arm 256 are each pivotably mounted in the region of their first ends 258, 260 around a horizontal axis which extends essentially transversely to the undercarriage.
  • a mounting base 262 for the upper swivel arm and a mounting base 264 for the lower swivel arm are fixedly attached to the mounting plate 252.
  • a bolt 278 for the lower swivel arm and a bolt 280 for the upper swivel arm each penetrate openings in the mounting plates 274 and 276 and the lower swivel arm 256 and the upper swivel arm 254, respectively, and thus provide a swivel connection between the swivel arms 254, 256 and the vibrating device (not shown as a whole).
  • connection of the connecting plate 272 to the carrier part 270 is in each case formed by angle elements 282 fixed on the carrier part 270.
  • Screw bolts 284 penetrate openings in the angle elements 282 and the connecting plate 272 and thus fix the carrier part 270 to the connecting plate 272.
  • a cylinder unit 286 On the mounting plate 252 is also a cylinder unit 286 via a cylinder carrier 288 with one of its parts, for. B. the cylinder part, pivotally mounted. With another part, e.g. B. a piston rod part 290, the cylinder unit 286 is pivotally connected to the lower pivot arm 256.
  • the upper swivel arm 254 is laterally spaced further from the mounting plate 252 and thus from the undercarriage frame 244 than the lower swivel arm 256. Therefore there is between the upper swivel arm 254 and the mounting plate 252 sufficient space for arranging the cylinder unit 286 is provided.
  • the cylinder unit 286 is e.g. B. a hydraulic cylinder unit for raising and lowering the parallelogram guide provided by the swivel arms 254,256 and the connecting plate 272 for the vibrating device. It is advantageous if, as shown in FIGS. 7 and 8, the cylinder unit 286 acts on the lower swivel arm 256 in the region of a central section 257. This ensures, on the one hand, that the lever effect provided for lifting the vibrating device by the lower swivel arm 256 does not exceed the force exerted by the cylinder unit 286 under load by the vibrating device, and, on the other hand, the lifting path provided by the cylinder unit 286 through the total length of the lower swivel arm 256 accordingly is enlarged.
  • the cylinder unit 286 can have a correspondingly short overall length, so that it does not protrude too far above the crawler chassis 240 and does not restrict the pivoting movement of an uppercarriage mounted on the undercarriage.
  • the bolts 278 and 280 are loosened on the upper and lower swivel arms provided on both sides of the undercarriage, so that the connection of the upper and lower swivel arms 254, 256 respectively to the connecting plate 272 and thus the vibrator is released. It is thus ensured that no components projecting laterally beyond the upper swivel arm, e.g. B. the vibrator, are connected to the excavator, so that the overall width of the excavator allows transport on public roads.
  • the upper swivel arm 254 can be adjusted in length in one of its end regions by screw elements known per se, so that when the vibrator is mounted on the excavator, the Angular position of the vibrator is adjustable relative to the excavator.
  • the structure of the vibrating device corresponds essentially to that with reference to the vibrating device described in FIGS. 1-4.
  • the combination of an excavator with a vibrating device according to the invention creates an inexpensive possibility for the production of base layers. Since there are always excavators on roads or track construction sites, which are used to work on the subsurface and for a variety of other tasks, these excavators can also be used to attach the base layers by attaching a vibrating unit. There is therefore no need to provide any additional construction equipment, which then has to be transported to the construction site for the production of the base layers and which has to be removed from the construction site after the work process has ended. The total costs for producing such a base course or the total construction costs and the maintenance costs of the construction equipment fleet are thus considerably reduced.
  • the excavator used in the combination according to the invention is suitable for exerting a very high pressure on the surface to be worked via the vibrating device, so that uniform and highly compacted base layers can be produced with the combination according to the invention.
