Definitions

  • the invention relates to a working machine unit, in particular for installation and compaction of paving layers, and a method for assembling the working machine.
  • Tarpaulin coatings are usually applied with finishers to which a building material, for example asphalt, concrete or gravel is supplied via a feeder or which have a reservoir for the building material, which is filled as needed.
  • a longitudinal conveyor transports the building material from the storage container or from a feed opening to a transverse distribution device, which distributes the building material evenly over a paving width.
  • a compacting beam guided above leveling bars smoothes and then compacts the building material on a substrate.
  • asphalt construction dominates because asphalt has a number of advantages.
  • the aim is to increase the degree of compaction and to reduce the thickness of the surface layers.
  • ceiling damage, cracks and flaking compact asphalt is used increasingly in which two layers are laid simultaneously hot-on-hot.
  • the installation is usually carried out either with two pavers, with the second paver installed directly behind the first paver, with the disadvantage that the second paver has to drive on the first installed paver layer.
  • special pavers are used that combine all the necessary work functions of two pavers in one machine.
  • an attachment for a paver which allows the simultaneous hot-on-hot laying of two layers and which consists of a second material storage bucket, a second transport device and a second distribution device mounted in front of a second screed.
  • the disadvantage here is that a provided with this accessory Paver claimed during transport from a construction site to a distant other site a large transport volume and heavy mobile crane equipment is needed.
  • a paver which is equipped for the simultaneous installation of at least two concrete pavement layers with a chassis, a chassis, at least two arranged on the chassis Mischgut matterern, each Mischgut disposer associated behind the chassis arranged transverse distributor and one longitudinal conveyor.
  • the two screeds designed as Hochverdichtungsbohlen be via two separate leveling beams, which are articulated on the chassis, pulled along by the paver floating.
  • a slipform paver with a supported by individually driven crawler chassis square frame in which two screeds are dragged successively swimming from the support frame.
  • This road construction machine is able to install two separate concrete inlay layers.
  • the disadvantage is that the pave width is limited by the slip formwork and the paving width are arranged within the crawler tracks.
  • the invention is based on the object to provide an improved work machine unit, in particular for installation and for compacting paving layers.
  • Such a work machine unit is formed according to the invention by a method for assembly with the features of claim 14th
  • a working machine unit in particular for installation and compacting of paving layers, comprises at least parts of a first and a second paver, in particular two commercially available pavers.
  • Both pavers each comprise at least one body, a feed opening or a reservoir for building material to be installed, a longitudinal conveyor for conveying the building material to a transverse distribution device for its distribution over a pave width and connected to the body via two leveling beams a compaction plank for compacting and / or smoothing of building material on a surface.
  • the second paver is arranged standing on the first paver and coupled with this directly or indirectly. At least the first paver has a landing gear.
  • the leveling beams of the second paver are modified such that the compaction pile of the second paver lies in the direction of travel of the working machine unit behind the compaction pile of the first paver in substantially the same height as the compaction pile of the first paver.
  • the leveling bars are lengthened and downwardly for this purpose.
  • the transverse distribution devices are preceded by their respective compaction booms in the direction of travel.
  • the body of the first working machine is for this purpose in particular designed so that it can carry the load of the second paver.
  • Such a work machine unit enables on the one hand the installation of a two-layer asphalt surface or the installation of outer layers of other materials. Two existing pavers only have to be combined in the manner described.
  • the transport of two individual pavers is significantly less complicated than the transport of a much larger combined paver. If necessary, the working machine arrangement can be disassembled again so that the pavers can also be used for other tasks, such as the installation of single-layer coverings.
  • the inventive arrangement of two compaction planks also makes it possible to create separate profiles for the two layers, eg rain gutters can be introduced.
  • the body of the second paver can be mounted directly on the body of the first paver.
  • a hoist such as a truck crane
  • the second paver preferably has a demountable chassis. Such an arrangement is particularly compact.

  • At least one mechanical quick fastener such as a snap fastener, as known from mechanical quick couplers or three-point linkage of self-propelled work machines.
  • a mechanical quick fastener such as a snap fastener
  • the leveling beams of the second paver are preferably interchangeable. In this way, both standard leveling beams for solo operation of the second paver as well as modified leveling beams for operation in the work machine unit can be mounted.

  • adapters for fixing the transverse distribution device of the second finisher are provided to arrange them in a particularly simple manner in the desired position for installation in the direction of travel immediately before the compaction plank of the second paver.
  • At least one of the longitudinal conveying devices is designed as a scraper chain conveyor. Because of their robustness, scraper chain conveyors are particularly suitable for the transport of typical building materials.
  • the longitudinal conveyor of the second paver has an extension element for feeding the building material to the transverse distributor of the second paver, because a greater distance between the longitudinal conveyor and the transverse distributor of the compactor due to the location of the second paver on the first and longitudinal displacements of the compaction pavers second paver results.
