Description

Technical Field

[0001] The utility model relates to a ground compactor, which can be used to compact ground materials, in particular asphalt. Background Art

[0002] In road construction or in the manufacture of runways at airports and the like, it is known to apply markings (often also called road markings) after the manufacture of the ground, which is usually built with bituminous material and compacted by one or more ground compactors. For this purpose, pre-markings are applied, for example, with the aid of special equipment, which indicate the route of the road markings to be applied in a further process step according to relatively thin and, for example, only interrupted guide lines. Liquid marking materials can be used for applying pre-markings as well as road markings, which are sprayed or applied to the previously compacted ground material. In particular in the area of ​​construction sites, it is also known to create temporary road markings by applying marking materials designed as wheel tracks in the manner of adhesive tapes. Utility Model Content

[0003] The purpose of the utility model is to provide a ground compactor and a method for operating the compactor, by using the method the manufacture of ground structure can be simplified.

[0004] According to the first aspect of the utility model, the purpose is achieved by a ground compactor for compacting ground materials (especially asphalt), the ground compactor comprising at least one compactor roller which can rotate on the compactor structure around a roller rotation axis which is substantially orthogonal to the longitudinal direction of the compactor, the ground compactor also comprising at least one marking unit supported on the compactor structure for applying marking material to the ground material passed by the ground compactor.

[0005] Since the compaction of the ground material (usually asphalt) is the last process or one of the last processes in the manufacture of ground structures, such as in road construction, the marking material can be applied to the surface of the ground material simultaneously with the ground compactor constructed according to the utility model, such as in the last run or one of the last runs of compacting the ground material. No additional work process or additional equipment is required for this process.

[0006] In one embodiment which is easy to realize and supports a defined positioning of the discharged marking material, at least one marking unit can be supported essentially immovably on the compactor structure.

[0007] In order to also gain access to the side edge regions of the compacted ground material, it is proposed that at least one marking unit which is supported essentially immovably on the compactor structure is supported on a side edge region of the compactor.

[0008] The edge pressing unit can be arranged on the compactor structure associated with at least one side edge region, in particular in combination with a marking unit immovably supported on the side edge region of the compactor structure, thus ensuring a fixed predetermined distance between the edge pressing unit and the marking unit transversely to the longitudinal direction of the compactor, resulting in a correspondingly defined predetermined distance of the applied marking material to the side edge of the compacted ground material.

[0009] In order to be able to produce more complex forms of road markings, it is proposed that at least one marking unit is movably supported on the compactor structure.

[0010] For this purpose, for example, at least one guide rail can be provided on the compactor structure, and at least one (preferably each) marking unit movably supported on the compactor structure can be moved along the at least one guide rail.

[0011] In order to be able to arrange the marking unit supported on the guide rail at different positions for outputting marking material, a marking unit drive can be configured to be associated with at least one (preferably each) marking unit movable along at least one guide rail, for moving the marking unit along at least one guide rail.

[0012] When at least one (preferably each) guide rail extends essentially in the direction of the roller rotation axis and / or when at least one (preferably each) guide rail is arranged behind the compactor roller in the longitudinal direction of the compactor, essentially the entire width of the ground material covered by the ground compactor or passed over during travel can be used to output marking material.

[0013] Particularly for smaller applications or for applying lane lines for pre-marking, at least one (preferably each) marking unit can comprise a spray can containing a liquid marking material.

[0014] For larger working ranges or also for applying final road markings, it is advantageous if at least one (preferably each) marking unit comprises a spray head and at least one marking material tank connected to the spray head for supplying liquid marking material is arranged on the compactor structure.

[0015] At least one (preferably each) marking unit may be designed to apply a pre-marking to a ground material.Alternatively or additionally, at least one (preferably each) marking unit may be designed to apply a road marking to a ground material.

[0016] In order to be able to produce non-permanent road markings, for example in the area of ​​construction sites, it is proposed to design at least one (preferably each) marking unit for applying the marking material as a wound tape.

[0017] For a defined operation of the at least one marking unit, it is proposed that the at least one (preferably each) marking unit is under the control of the drive control unit and can be operated to output the marking material by issuing a control command from the drive control unit.

[0018] According to another aspect of the present invention, the object stated at the beginning is achieved by a method for operating a ground compactor constructed according to the present invention, wherein, when the ground compactor moves on the ground material, at least one marking unit is operated to apply marking material to the ground material.

[0019] For example, when producing edge areas of a road, for example constructed with asphalt, if the edge pressing unit is operated to form an edge of the ground material over which the ground compactor runs, at least one marking unit is operated to apply marking material to the ground material as an edge marking. It can thus be ensured that the marking material applied during the process is at a defined distance from the edge of the ground material produced by the edge pressing unit.

[0020] If the marking unit for applying the marking material is operated as a winding belt, it is advantageous if the marking unit is arranged in front of at least one compactor roller in the direction of movement of the soil compactor. The winding belt delivered by the marking unit is thus rolled over by the soil compactor immediately after delivery and is firmly pressed against the surface of the soil material which is also compacted at the same time.

[0021] In particular for producing pre-markings of complex shapes, it is recommended that when operating at least one marking unit to apply the marking material for pre-marking:

[0022] - generating a portion of the pre-marking during a marking run and generating another portion of the pre-marking during another marking run,

[0023] or / and

[0024] A pre-marked part is produced by a marking unit and another pre-marked part is produced by another marking unit.

[0025] In order to ensure that marking material is output only where road markings are supposed to be present according to previous planning, it can be provided that at least one (preferably each) marking unit - which is used to apply marking material to the ground material - operates based on position data representing the position of the ground compactor on the ground material (preferably GPS data) and / or based on marking model data.

[0034] Figure 1 A ground compactor 10 for road construction is shown, which in the illustrated design example travels over ground material 12 to be compacted, for example asphalt, and thereby compacts it. The ground compactor 10 extends substantially in a compactor longitudinal direction L and in the illustrated design example comprises two compactor rollers 14, 16 which are arranged at a distance from one another in the compactor longitudinal direction L. Figure 1 The ground compacting machine 10 shown in Figure 1 The state shown is a movement in the movement direction B along the floor material 12 , in particular in its edge region 18 .

[0035] exist Figure 2 In the process shown, which is the last pass or one of the last passes of the ground material 12 to be compacted, an edge 24 of the ground material 12 is formed by means of an edge pressing unit 20, which is arranged on the ground compactor 10 in the edge area 18 of the ground material 12, with the aid of a correspondingly formed forming tool 22, in particular by pressing the ground material 12 present in this area.

[0036] A marking unit, designated as a whole by 26, is arranged on the soil compacting machine 10. In the illustrated embodiment, the marking unit 26 comprises a container for a liquid marking material M, which is designed in the form of a spray can 28. The spray can 28 is supported replaceably on a carrier 32 which is fixed to a compacting machine structure 30 of the soil compacting machine 10, so that the spray can 28 can be replaced by a new spray can when the marking material M contained in the spray can 28 has been completely discharged.

[0037] like Figure 1 and Figure 2 As shown, by delivering the marking material M onto the surface of the ground material 12 compacted by the ground compactor 10 and processed in the edge region 18 to form the edge 24, an interrupted guide line L of the pre-marking V is generated, for example, in the movement direction B. Since the marking unit 26 is fixedly supported on the compactor structure 30 in the side edge region 34 of the ground compactor 10 and therefore has a defined and unchangeable distance from the edge pressing unit 20 transversely to the compactor longitudinal direction L and essentially in the direction of the roller rotation axis W of the two compactor rollers 14, 16, the pre-marking V generated by the marking unit 26 also has a defined and constant distance from the edge 24 of the ground material 12 compacted and formed in the edge region 18.

[0038] The marking unit 26 can be activated by an operator controlling the ground compacting machine 10 in order to generate a pre-marking V, and then the actual road marking is generated along the pre-marking V, for example by a separate device. Alternatively or additionally, the marking unit 26 can be activated automatically. For this purpose, position data, such as GPS data, which reflect the position of the ground compacting machine on the ground material 12 to be compacted, can be used, for example, by means of a satellite-based positioning system. In addition, model data for the route of the ground material 12 or the road to be produced can already be generated in the planning phase of the ground to be produced, i.e. the road in the example shown, which model data can also contain information about the route of the pre-marking V, which is generated, for example, along the edge 24 of the compacted ground material 12. Based on the position data and the marking model data, the marking unit 26 can then be activated by a control unit arranged on the ground compacting machine 10 to output the marking material M.

[0039] It should be noted that the marking unit and, if necessary, the edge pressing unit can also be arranged on the other side edge region of the soil compacting machine 10. Figure 1 Cannot be seen in Figure 1 When moving in the moving direction B opposite to the moving direction of the ground compactor 10, it can also be processed. Figure 1 The wheel region 36 shown in the center rear part can in particular be applied with a marking material M.

[0040] Figure 3 and Figure 4An alternative embodiment of a soil compacting machine 10 is shown. In this soil compacting machine 10, two marking units 26, 26' are arranged behind the compacting machine roller 16 in the longitudinal direction L of the compacting machine. The two marking units 26, 26' each comprise a carrier 32 and a container designed in the form of a spray can 28, which is supported movably on a guide rail 38 substantially in the direction of the roller rotation axis W, and which contains a liquid marking material M. In order to move the marking units 26, 26' or the carriers 32 along the guide rail 38, a marking unit drive can be provided in connection with each marking unit 26, 26', which moves independently of the respective other marking unit in the longitudinal direction of the guide rail 38, i.e. also substantially in the direction of the roller rotation axis W. Such a marking unit drive can comprise a drive motor, for example an electric motor, which drives a continuous belt running in the direction of the guide rail 38 to move via respective deflection rollers. The respective carrier 32 can be fixed to the continuous belt.

[0041] The movability of the marking unit 26, 26' along the guide rail 38 enables the generation of a guide line L or L' with a pre-marked V or V' of almost any shape or any orientation. Figure 4 As can be seen in FIG. 1 , in particular, a guide line L in the edge region 18 and a guide line L′ away from the edge region 18 can also be generated. Figure 3 and Figure 4 This is shown in particular by the fact that the guide line L' can form part of a pre-marking V', which is intended for producing an arrow on the ground material 12. When the ground compacting machine 10 moves in the moving direction B, only half of this pre-marking V can be generated by the marking unit 26'. For example, the other half can be generated during another travel. Alternatively, the two marking units 26, 26' can be used to generate the entire pre-marking V', i.e. the outline of the arrow, together during a single travel.

[0042] The two marking units 26 , 26 ′ can also be activated, for example, by an operator to apply the marking material M. Alternatively or additionally, in this embodiment, the two marking units 26 , 26 ′ can also be activated to output the marking material M by taking into account the position data of the ground compacting machine 10 and a marking plan that reflects the marking model data for applying a pre-marking to the ground material 12 .

[0043] It should be noted that Figure 1 The fixed marking unit visible in the Figure 3on the ground compactor 10, so that, for example, a pre-mark can be applied in the edge area by means of a fixed marking unit, and the pre-mark can be produced by two marking units, which are basically movable over the entire width of the ground compactor 10 in the direction of the roller rotation axis W or transversely to the longitudinal direction L of the compactor, the pre-mark having a greater distance to the edge 24 of the ground material and having a more complex shape.

[0044] exist Figure 5 You can see Figure 3 and Figure 4 A variation of the design example shown. In this design form, each of the marking units 26, 26' comprises a spray head 40 supported on a respective carrier 32, via which the marking material M can be delivered. A marking material tank 42 is also provided on the ground compactor 10, which is connected to the spray heads 40 of the two marking units 26, 26' via a pipeline 44, so that the liquid marking material contained therein is guided to the spray heads 40 of the two marking units 26, 26' and delivered via them onto the ground material 12.

[0045] Figure 5 The embodiment shown is particularly suitable for larger construction projects in which relatively large quantities of marking material M are to be output. Figure 5 The embodiment type shown is particularly suitable also for generating the actual road markings themselves, without having to generate pre-markings beforehand.

[0046] exist Figure 6 In the embodiment of the soil compacting machine shown, the marking material M is applied to the soil material 12 not in liquid form but in the form of a wound strip A. The wound strip A is supported in a wound manner on a carrier 32, which in turn is supported movably substantially in the direction of the roller rotation axis W on a guide rail 38, which is arranged behind the compacting machine roller 16 in the longitudinal direction L of the compacting machine. When the soil compacting machine 10 is moved in the movement direction B, the marking material provided in the form of the wound strip A for producing the road marking F can be pressed onto the surface of the soil material 12, for example, according to the marking model data, and the road marking F is produced there. The wound strip A has adhesive properties similar to those of an adhesive tape, so that when the soil compacting machine 10 is moved, the wound strip A unwinds in the movement direction B and adheres to the soil material 12. For example, in order to produce a road marking F that is interrupted in the movement direction B, a cutting tool can be provided on the carrier 32, which cuts the marking material M at a suitable location. In order to prevent the marking material M from interacting with the ground material 12 at locations where the road marking F is to have interruptions, the carrier 32 can also be displaced in the height direction.

[0047] To improve Figure 6The bonding effect of the marking material M in the illustrated design example can be provided that when such marking material M is applied to the ground material 12, the ground compactor 10 is moved so that the marking unit 26 is positioned along the movement direction of at least one of the front compactor rollers 14, 16. Figure 6 In the example shown, the ground compactor 10 will move in a moving direction B' opposite to the moving direction B. The marking material M output by the marking unit 26 is rolled over by the ground processing roller 16 (also the ground processing roller 14 in the example shown) following in the longitudinal direction L of the compactor and is therefore pressed more strongly against the surface of the ground material 12.

[0048] The application of marking material M in the form of a wound strip A is particularly suitable for construction site areas where such marking material M is only applied temporarily and where no road marking is produced by a color material that adheres strongly to the ground material 12 .

[0049] Figure 7 The operating principle of such a soil compacting machine 10 is shown when applying a marking material M, for example a liquid marking material. The marking unit 26 is controlled by a control unit 46, which controls the marking unit 26 to move along the guide rail 38 on the one hand and to discharge the marking material M to a position provided for this purpose on the other hand. The position P of the soil compacting machine 10 and the pre-marking V generated in this case can be displayed on a display unit 48, which is designed as a tablet computer or the like, for example. When the soil compacting machine 10 is in the position provided for this purpose and the pre-marking V is to be generated, the operator can send corresponding control commands to the control unit 46 via corresponding input elements, and the control unit 46 then positions the marking unit 26 in a corresponding manner by moving along the guide rail 38 and controls it to discharge the marking material M. As already explained above, this control can also be carried out based on position data and marking model data, so that no interaction of the operator is required and the operator only needs to be shown on the display unit 48 the position of the soil compacting machine 10 and the position where the pre-marking V or, if necessary, the road marking F is to be generated.

[0050] The position data also essentially indicate exactly the position of the ground compacting machine 10 in space and thus on the ground material 12 to be compacted, which can be obtained, for example, by Figure 7The display unit 48 shown provides, as indicated by the symbol 50 shown thereon, direct communication with a GPS satellite system, for example, and for this purpose has a corresponding receiving unit and is designed to evaluate the received data to determine the position. Alternatively or additionally, such a receiving unit 52 can also be provided separately from the display unit 48, which is also designed for evaluating the received data and thus for determining the position and is connected to the display unit 48 for data exchange. For example, this receiving unit 52 can be arranged on the soil compacting machine 10 itself, for example on the cover 54 of an operator station 56 arranged on the soil compacting machine 10.
