Definitions

  • the present invention relates to a road paver with a screed according to the preamble of claim 1.
  • Road pavers have a floating screed, which acts on the mix with its own weight and the energy of the compaction units and ensures the pre-compaction and profiling of the pavement to be paved.
  • Different versions of screeds are used, e.g. B. rigid planks whose width cannot be changed, rigid planks, the width of which can be changed with the help of separate attachments, and extendable planks, the width of which can be varied with the help of extending parts.
  • the installation dimension of a screed without extending or add-on parts is referred to as the basic width or the basic screed.
  • separate widening parts can also be attached to the pull-out parts.
  • the paving width of such extendable screeds as well as other settings in order to ensure the processing of different mixes in different paving thicknesses in high quality can be done from external control stations attached to the respective end areas of the paving screed (also Called screed control station) can be controlled from.
  • EP 2 644 454 A1 discloses an outside steering position of a screed with a control panel provided thereon.
  • the control panel has a fastening section on its underside with which it can be fastened to the outside steering position.
  • the control panel can be plugged with its fastening section onto a tubular element on a holder of the screed and secured thereon.
  • an electrical connection for an electrical coupling process is provided on the operating panel on its underside, but separate from the fastening section both in terms of design and function.
  • the EP 2 578 748 A1 also discloses an outside steering position for a screed.
  • the outside steering position has a control panel that is attached to a mechanical mounting bracket.
  • the control panel has electrical connections on its underside.
  • connection cables of various lengths or additional extension cables are used to bridge varying distances.
  • connecting cables of different lengths have to be stored and changed as required in the course of road construction work, which is associated with operational disruptions and additional work for the operator.
  • the object of the present invention is therefore to provide an improved road finisher in order to eliminate the disadvantages listed above.
  • a paver is provided with a paving screed which has a base screed and extending parts that are transversely displaceable on the base screed relative to a direction of travel of the paver, an outside control station being mounted on an outer end region of one of the extending parts and via a connecting cable to the base screed or to one of the extending parts is electrically connected, wherein a cable reel with a drum for winding the connecting cable, an axis on which the drum is rotatably mounted, and a pretensioning element is arranged in the base screed or in one of the extending parts to accommodate the connecting cable and provide it in variable length.
  • Another advantage of the invention is that the number of cables required is reduced, since the same cable can be used for all working widths. In addition, the cable is stowed in a protected place when it is not needed, for example, when adding extension parts.
  • a sideshifter is arranged on an outer end region of the pull-out part, the outside control station being connected to the sideshifter via a plug connection.
  • the connecting cable preferably has a first length which corresponds at least (possibly with an excess length of up to 5% or 15%) to a maximum required distance between the outside steering position and an electrical connection point of the basic screed or an extending part.
  • connection cable outside the cable winder always has the correct length and a disturbing sagging of the cable with small working widths is avoided.
  • the cable winder preferably has a slip ring in order to establish a movable electrical connection between the lines of the connecting cable rotating with the drum and the electrical connection point of the basic screed or of an extension part.
  • the connecting cable has a second length which is greater than a maximum required distance between the outside steering position and an electrical connection point of the basic screed or an extending part.
  • a first end of the connecting cable can be connected to the external steering position and a second end of the connecting cable can be connected directly to the basic screed or to one of the extending parts.
  • This enables a static electrical connection between the connecting cable and the electrical connection point of the basic screed or an extending part, which is not rotated with the drum. This ensures reliable power transmission to the auxiliary control station during operation.
  • the connection is kept free of dirt and dust.
  • the connecting cable can be unrolled from the drum in two different unwinding directions at the same time.
  • part of the connection cable connected to an auxiliary control station is pulled in one direction, while another part is unwound in the opposite direction and is collected behind the drum.
  • a space for the unwinding of the connecting cable is expediently provided between the drum and the connection point of the basic screed or the pull-out parts. This space creates space for a part of the connecting cable that is unwound behind the drum.
  • a compensation section is provided which is pre-twisted inside the drum. This also enables the connection cable to be connected directly to the electrical connection point of the basic screed or an extending part. This saves the space required for unwinding the connecting cable behind the drum, since a part of the connecting cable that is unwound in the opposite direction to the pull-out direction is twisted to a torsion-free state and accumulated in the drum.
  • the compensation section of the connecting cable that is unwound in the interior of the drum is preferably a helical cable.
  • a coiled cable is particularly suitable for absorbing twisting.
  • the cable winder has a latching mechanism in order to keep the connecting cable under at least largely constant tensile stress when it is pulled out and to reduce the fatigue of the cable.
  • Figure 1 shows a road paver 1 for producing a road surface B.
  • the road paver 1 has a material bunker G for receiving a paving material E.
  • the paving material E can be moved out of the material bunker G by means of a longitudinal conveyor device, not shown, backwards against a direction of travel F to one on the paver 1 stored screed 2 transported.
  • the paving material is spread out in front of the screed 2 and compacted by the screed 2 in order to produce the new road surface B.
  • Figure 2 shows the screed 2 in a rear view in the direction of travel. It comprises a basic screed 3, which can be widened by a left and a right extension part 4a, 4b. Here the pull-out parts are shown in their extended state.
  • the one in the Figure 2 The screed 2 shown also has an outside steering position 5a, 5b, which is usually mounted with a fastening tube or carrier 16 on the outer end region E of an extension part 4a, 4b. It is also possible to attach the outside steering position 5a, 5b directly to the basic screed 3.
  • Figure 3 shows a rear view of the screed 2 with side shifters 11a, 11b.
  • Left and right sideshifters 11a, 11b are mounted on the outer end portions E of the pull-out parts 4a, 4b.
  • the external control stations 5a, 5b are connected to the respective sideshifter 11a, 11b via a plug connection 12.
  • a connection option for connecting the external control stations 5a, 5b to the pull-out parts 11a, 11b or the basic screed 3 can be provided in the sideshifter 11a, 11b. It is also possible to arrange further widening parts (not shown) between the pull-out parts 4a, 4b and sideshifts 11a, 11b.
  • the entire construction of the components with the pull-out part 4a, 4b, widening part and sideshift 11a, 11b is referred to as the "pull-out part".
  • a connecting cable 6 is provided for connecting the external control station 5a, 5b to the screed 2.
  • the connecting cable 6 can be electrically connected to the base screed 3 or to one of the pull-out parts 4a, 4b and, in its unused state, can be stowed in a cable reel 7 according to the invention. If the working width changes when extending and retracting the pull-out parts 4a, 4b during the cultivation, the pulled-out length of the connecting cable 6 also varies accordingly by winding and unwinding.
  • the basic screed 3 and the extending parts 4a, 4b have electrical connection points, which are each identified here with A1 and A2.
  • D1 and D2 each essentially define the maximum required distance between the outside steering position 5a, 5b and the electrical connection points A1, A2 of the basic screed 3 and the extending part 4a, 4b, if the Pull-out parts 4a, 4b are completely extended and this corresponds to the maximum required working width.
  • Figure 4 shows a side view of a cable winder 7 arranged in a base screed 3 or an extension part 4a, 4b with a connecting cable 6 in the rolled-up state.
  • the cable reel 7 can be held by a frame (not shown here) or can be fastened directly to a wall of the basic screed 3 or an extension part 4a, 4b by means of a holder.
  • the cable winder 7 has a drum 8, which is used to wind up the connecting cable 6, and an optionally stationary shaft 9 on which the drum 8 is rotatably mounted.
  • the drum 8 can be accommodated (not shown) between two drum disks lying parallel to one another, which hold the connecting cable 6 on the drum 8 at the side.
  • the cable reel 7 also comprises, in a known manner, a prestressing element 10, not shown in detail, e.g. B. a spring which is rotatably mounted between the drum 8 and the fixed axis 9. It is also possible to arrange the spring 10 at another point of the cable reel 7, where the spring is in contact with the drum 8.
  • This prestressing element 10 is tensioned when the connecting cable 6 is pulled out of a stowage space 17 of the basic screed 3 or an extension part 4a, 4b. After the connecting cable 6 has been released, the prestressing element 10 drives the drum 8 back.
  • the cable winder 7 can have a locking mechanism 15, e.g. B.
  • the connecting cable 6 is separated from the outside steering position 5a, 5b or the side shift 11a, 11b, it is automatically rewound. It is also possible to attach the locking mechanism 15 behind an opening 18 of the storage space 17 of the basic screed 3 or an extension part 4a, 4b from which the plug 19 of the connecting cable 6 is pulled out.
  • the invention also provides for the cable winder 7 to be designed without a latching mechanism 15 and for the connecting cable 6 to be kept under a constant tensile stress.
  • the cable reel 7 shown is provided with one or more slip rings 13.
  • Slip rings 13 are used to transfer electrical energy between two separate parts that rotate relative to each other.
  • a first end 20 of the connecting cable 6 is connected to the auxiliary steering position 5a, 5b and a second end 21 of the connecting cable 6 is connected to the lines 22 of the cable 6 on the slip ring 13 on the axle 9.
  • a line 23 extends between the slip ring 13 and the electrical connection points A1, A2. Via these, the slip rings 13 are connected to an electrical connection A1, A2 of the basic screed 3 or an extension part 4a, 4b connected. It is also possible to connect the lines 22 of the cable 6 to the sliding contacts (not shown) mechanically fastened in the inner part of the cable winder 7, the sliding contacts resting against the slip rings 13.
  • the axis 9 and the slip rings 13 remain immovable in the rest position. Instead, the electrical lines 22 of the connecting cable 6, with or without the sliding contacts, are set in motion by the rotation of the drum 8.
  • Figure 5 shows a side view of the cable winder 7 arranged in a base screed 3 or an extension part 4a, 4b with a connecting cable 6 in the unwound state.
  • a first, developed length L1 of the connecting cable 6 can be seen here. This corresponds at least to the maximum required distance D1, D2 between the auxiliary steering position 5a, 5b and an electrical connection A1, A2 of the basic screed 3 or an extension part 4a, 4b. With an excess length of up to 5% or 15%, this length L1 can correspond to a maximum required distance between the outside steering position and an electrical connection point of the basic screed of an extending part.
  • Figure 6 Figure 3 shows a further embodiment of the invention.
  • a first end 20 of the connecting cable 6 is connected to the auxiliary steering position 5a, 5b and a second end 21 of the connecting cable 6 is connected directly to the connection point A1, A2 of the basic screed 3 or to one of the extending parts 4a, 4b and the connecting cable 6 is simultaneously in two different ones Unrolling directions R1, R2 can be unrolled from the drum 8.
  • the connecting cable 6 here has a second length L2 which is greater than a maximum required distance D1, D2 between the auxiliary steering position 5a, 5b and an electrical connection A1, A2 of the basic screed 3 or an extension part 4a, 4b.
  • Figure 8 Figure 3 shows another embodiment of the invention.
  • a first end of the connecting cable 6 is connected to the auxiliary steering position 5a, 5b and a second end of the connecting cable 6 is connected directly to the connection point A1, A2 of the basic screed 3 or to one of the pull-out parts 4a, 4b.
  • the connecting cable 6 again has a second length L2 which is greater than a maximum required distance D1, D2 between the auxiliary steering position 5a, 5b and an electrical connection A1, A2 of the basic screed 3 or an extension part 4a, 4b.
  • a compensation section 6A of the connecting cable 6 is pre-twisted inside the drum 8. When unwinding, the portion of the connecting cable 6 wound on the drum 8 is unwound while the compensation portion 6A is rotated inside the drum 8 in a torsion-free state, and the length of the compensation portion 6A inside the drum 8 remains constant.
  • Figure 9 shows the drum 8 in an approximately half-unrolled state in which the compensation section 6A inside the drum 8 is in a torsion-free state. From this point on, as the connecting cable 6 is pulled out further, the compensation section 6A inside the drum 8 becomes opposite to FIG Figure 8 shown condition twisted. This state is in Figure 10 shown.
  • a helical cable can be used for the compensation section 6A of the connecting cable 6.
