Definitions

  • the invention relates to a method for forming a multi-layer road finisher according to the preamble of claim 1.
  • the invention further relates to a multi-layer road finisher according to the preamble of claim 7.
  • Road coverings are usually formed from essentially three layers, namely a base layer, a binder layer and a cover layer. It has been found that a high quality pavement can be achieved when the topmost paving layers are installed in immediate succession so that the hot paving layer is applied to the still hot binder layer. In this context one speaks in the jargon of a "hot-on-hot" -leading.
  • the present invention seeks to provide a method for forming a multi-layer road paver and a multi-layer paver, with independent road pavers are used, which can also be used for the production of conventional monolayer road surfaces.
  • a method for achieving this object comprises the measures of claim 1. Accordingly, it is provided to arrange an upper paver on a lower base road paver. So it is used for multi-layer installation two on the piggyback principle stacked independent paver.
  • the base paver serves as a carrier for the upper paver. Both the basic road paver and the upper paver can be used separately as needed to produce conventional single-ply pavements.
  • the entire upper paver for conversion into a multi-layer paver above the base paver.
  • the upper paver is at a distance above the ground, so that its chassis is not supported on the ground and therefore only the chassis of the base paver serves as a chassis of the entire multi-layer paver.
  • the landing gear of the upper paver hangs in the air, so that all road pavers are carried together by the chassis of the lower base paver.
  • the chassis is disconnected from the upper paver before it is placed on the lower base paver. This reduces the weight of the entire multi-layer paver.
  • the chassis of the base paver then only needs to carry the upper paver without its landing gear.
  • the built-in or compacting coal and / or auger is dismantled from the upper paver before the upper paver is placed on the lower base paver.
  • the upper paver can be provided to put the upper paver on the base paver, so that the base paver, especially his chassis, carries the upper paver.
  • the chassis of the upper paver does not serve for Moving the multi-layer paver, this is only the chassis of the base paver.
  • the method preferably assign a support device for the upper paver to the base paver releasably.
  • the carrying device can fulfill several tasks. Preferably, it serves for easy coupling of the upper paver to the lower base paver. Alternatively or additionally, however, the carrying device also serves for attaching the screed removed from the upper paver and / or the auger.
  • the support device can be fully supported on the base paver, so that it carries both the support device and the upper paver. But it is also conceivable to support the support completely or at least partially on the ground. Then at least part of the carrying device and the top paver arranged thereupon rests on the ground. The support device then at least partially assumes the function of the chassis of the upper paver, which can be degraded by the same or is unloaded when the upper paver is arranged for multi-layer installation on or on the lower base paver.
  • a multilayer road paver for solving the above-mentioned problem has the features of claim 7. It is envisaged to arrange an upper paver on the base paver, which serves to form the second road surface on the bottom first paver produced by the base paver. Accordingly, according to the invention, two independent road pavers are arranged one above the other according to the piggyback principle.
  • the lower base paver carries the upper paver whose suspension remains unused and unloaded, if necessary, even before putting it on the lower base paver can be removed.
  • the support means includes one or more means for holding the upper paver above the lower base paver.
  • the support device can be completely supported on the base paver, but also fully or partially supported by a separate chassis, preferably several tires, together with the chassis of the base paver on the ground.
  • the carrying device need only be attached to the lower base paver, so that essentially only the pushing or pulling force of the chassis of the base paver is transferred to the support means, so the base paver only pulls or pushes the support device with the top paver arranged thereon , Then the suspension of the support device does not need to have its own drive, although in an alternative embodiment of the invention, a separate drive of the chassis of the support device would also be conceivable.
  • the carrying device need only have at one end a suspension of preferably one or more wheels, while the other end of the support device rests on the base paver.
  • the carrying device with the upper paver is then saddled up on the base paver. It is also conceivable that the carrying device is supported with the upper paver at least partially on the attached to the support screed for the upper paver or both screeds for the upper paver and the base paver.
  • the support device with the associated upper paver can also be completely supported on the own chassis, which is then preferably also driven.
  • the suspension of the support height adjustable is provided to make the suspension of the support height adjustable.
  • the weight load of the base paver by the support means and especially the top paver arranged thereon needs to be changed as needed during the installation of the road surfaces.
  • the height adjustability of the chassis of the support device can also serve to change the weight, which exerts at least one screed on the newly installed road surface during installation, namely to adapt to the needs.
  • the carrying device may be provided with at least one storage container for a type of road building material.
  • This reservoir can serve as an additional reservoir to the reservoir of the base paver, but also the reservoir replace the top paver or the paver.
  • At least one means for transferring road construction material from the upper paver to the auger for the road construction material is assigned to the surfacing layer to be produced by the upper road paver, in particular cover layer.
  • the means associated with the carrying device thus bridges the distance of the road finisher to the distribution auger associated therewith, which is increased by the arrangement of the paver above the base paver.
  • the support device is also associated with a compactor screed or screed of the upper paver.
  • the support device thereby carries those components of the upper paver who can no longer be arranged on the paver because of its arrangement on the base paver and have been dismantled from the top paver for multilayer installation for the purpose of retrofitting the two independent road paver for multi-layer paver.
  • This support frame can encompass both the upper paver and the upper paver where necessary with the remaining chassis and / or reservoir so that to piggyback the top paver on the base paver only the screed and optionally the auger are rebuild from the top paver on the support frame.
  • Fig. 1 shows a multilayer road paver for the simultaneous production of two layers of a multilayer road surface.
  • a binder layer and an overlying cover layer can be produced simultaneously, that is to say directly one after the other, whereby it is possible to install two layers, above all the binder layer and cover layer, "hot-on-hot”.
  • the multilayer road paver shown in FIG. 1 has two full-fledged, commercially available road pavers, each of which can be used individually for producing a single-layer road surface.
  • an upper independent road paver 11 is arranged above a lower base paver 10.
  • the upper paver 11 is smaller than the lower paver 10, because usually the cover layer is thinner and therefore less mass to install compared to the lower layer. If necessary, but also the upper paver 11 can be the same size as the basic paver 10, so have the same installation performance.
  • the upper paver 11 is arranged according to the piggyback principle on the base paver 10, which thereby serves as a carrier device, namely for the upper paver 11.
  • the chassis of the paver 11 is removed to reduce weight. This is thus arranged in the embodiment of FIG. 1 without his chassis on the base paver 10.
  • the chassis of the paver 11 is not required for the formation of multi-layer paver, because according to the invention the upper paver 11 is placed in a raised position above the base paver 10, in which the chassis is already spaced from the ground 12, that is not supported on the floor 12.
  • the upper paver 11 it is possible to arrange the upper paver 11 with its chassis above the base paver 10. Even then, the chassis of the paver 11 is at a distance above the ground 12, so that the chassis "in the air" depends and the upper paver 11 not carries and thus in multi-layer installation is inactive, so does not need to be driven.
  • the piggyback arrangement according to the invention of the upper paver 11 above the base paver 10 has the advantage that the multilayer paver is driven only by the chassis 13 of the base paver 10, whereby synchronization of the drives of the base paver 10 and the upper paver 11 - albeit this with his chassis would be supported on the floor 12 - is avoided.
  • the basic road paver 10 shown has a chassis 13, which is designed as a crawler chassis. However, the invention is not limited thereto.
  • the basic paver 10 of the multi-layer paver may also have another chassis, for example a wheel chassis.
  • the basic road paver 10 contains all the facilities that it needs for the installation of a lower layer of the pavement to be produced, so seen in the direction of installation 14 front hopper 15, at least one auger 16 behind the chassis 13 and a screed 17 behind the auger 16.
  • the Screed 17 is preferably a high-density screed.
  • At the base road paver 10 therefore no conversions are required for retrofitting the same for multi-layer paver.
  • the chassis From the upper paver 11, which is placed according to the invention on serving as a carrier base paver 10, the chassis, the auger 18 and the screed 19 are removed in the illustrated embodiment.
  • the chassis can but if necessary remain on the paver 11.
  • the multilayer road paver shown in FIG. 1 has a carrying device embodied here as a supporting frame 20.
  • the support frame 20 is fully supported on the ground by front wheels 21 and rear wheels 22.
  • the front wheels 21 are located in the installation direction 14 in front of the chassis 13 of the basic road paver 10, while the rear wheels 22 are located near the rear of the chassis 13.
  • the wheels 21 and 22 have no drive, so they are freely rotatable.
  • the support frame 20 is connected to the base paver 10 via at least one coupling point 23. This crosspoint 23 may in the illustrated support frame 20 with front wheels 21 and rear wheels 22 may be omitted.
  • the support frame 20 is coupled to the base paver 10 via a pusher point 24.
  • the pusher point 24 is configured to transmit only horizontal forces between the support frame 20 and the base paver 10, but not vertical forces.
  • the pusher point 24 only serves to move the support frame 20, which does not have its own drive, with the road paver 11 arranged thereon from the base paver 10 in the installation direction 14, especially to push it in front of it.
  • the pusher point 24 may be omitted. It is further provided by a height adjustment of at least the rear wheels 22 and / or the coupling point 23 during the installation of the road surfaces to relieve the base paver 10, in particular the screed 17 hanging thereon.
  • a height adjustment of the rear wheels 22 and / or the coupling point 23 by suitable mechanically, electrically, hydraulically or pneumatically operated lifting means.
  • the upper paver 11 On the support frame 20 of the upper paver 11 is attached. As a result, the upper paver 11 is mounted on the lower base paver 10 with the aid of the support frame 20.
  • the lower base paver 10 serves as a carrier device and at the same time to drive the support frame 20 with the road paver 11 arranged thereon.
  • the upper paver 11 is detachably connected to the support frame 20, at appropriate locations. Preferably, the upper paver 11 is connected to approximately horizontally extending upper beams 25 of the support frame 20, for example screwed. For the exact positioning of the upper road paver 11 on the support frame 20, stops or positioning means may be provided on the upper paver 11 and / or support frame 20.
  • the auger 18 and the screed 19 for the upper paver 11 also carries the support frame 20. Behind the screed 17 of the basic paver 11, the auger 18 of the paver 11 and behind the screed 19 of the upper paver 11 are attached to the support frame 20. At least the screed 19 is arranged vertically adjustable at the rear end of the support frame 20. Alternatively, the height adjustment of the screed 19 or the auger 18 by a height adjustment of the rear wheels 22 of the support frame 20 or the coupling point 23 between the base paver 10 and the support frame 20 done.
  • Fig. 4 shows the support frame 20 with the front wheels 21 and the rear wheels 22 and the screed 19 and the auger 18 for the upper paver 11. From this figure it can be seen that the rear wheels 22 at a rear end of a rocker 26th are stored. The opposite front end of the rocker 26 is pivotable about a horizontal axis of rotation 27. For pivoting the rocker 26 is used in the illustrated embodiment, at least one pressure medium cylinder 28. At the rear end of a leveling beam 29, preferably a pair of parallel leveling beams, the screed 19 is attached. Opposite front ends of the leveling beams 29 are pivotally hinged to the support frame 20. By at least one pressure cylinder 30, the leveling bars 29 are height adjustable.
  • the support frame 20 shown in FIG. 4 has a storage container 31 on its front side. This can be designed so that it increases the reservoir 15 of the base paver 10. However, it is also conceivable that the storage container 31 on the support frame 20 replaces the storage container 15 of the base paver 10. In this case, before the conversion of the basic paver 10 for multi-layer paver of the basic paver 10 of the reservoir 15 to dismantle. Furthermore, in the multilayer road paver shown here, the hopper 31 at the front end of the support frame 20 is assigned a dump bin 32. Likewise, a dump bin 33 is associated with the reservoir 34 of the upper paver 11.
  • the reservoir 31 on the support frame 20 serves to receive the material for the road layer underlying the cover layer, preferably the binder course, which is installed by the base paver 10. In contrast, the reservoir 34 serves to receive the cover layer material, which is installed by the upper paver 11.
  • a conveyor which serves to feed the reservoir 34 of the upper paver 11 with cover layer material. It is then no separate feeder required. Instead, can be filled by a truck by means of the conveyor of the reservoir 34 of the upper paver 11. As usual, the truck will be pushed by the multi-layer paver.

Then the upper paver 11 is placed on the base paver 10 by the piggyback principle. In the multilayer road paver shown here, the upper paver 11 is placed on the support frame 20. This can be done after the support frame 20 is connected to the base paver 10. However, it is also conceivable first to set up the upper paver 11 on the support frame 20 and then, if the auger 18 and the screed 19 are not yet attached to the support frame 20 to drive the base paver 10 from behind into the support frame 20, whereby the lower Basic paver 10 passes under the upper paver 11.
