Definitions

  • the invention relates to a screed assembly with a workstation according to the preamble of claim 1.
  • the functions of the screed are regulated from the driver's cab of the paver.
  • different working parameters can be set on the components of the screed from the driver's cab.
  • the functions of the screed can be controlled by means of a control unit which is attached to the side of the screed.
  • the staff usually operates the control unit while it runs alongside the screed during installation, or from a catwalk, which is mounted transversely behind the screed on the screed frame. From there, however, a flawless control of the control unit is almost impossible and the staff must concentrate on several things at the same time, which can lead to accidents.
  • the staff to operate the attached to the screed control unit comes very close to the work area of the screed, where accidents at work can never be completely ruled out.
  • the catwalk is not intended as a workplace for a longer stay on it, for example, to control from there, the control unit.
  • the catwalk should primarily allow the operating personnel to cross the freshly installed road surface without thereby stepping on the hot, possibly still uncomplicated inserted material, which could lead to undesired impressions.
  • the object of the present invention is to provide a screed arrangement which improves the occupational safety for the operating personnel and ensures optimized installation, wherein in particular the installation of a new road surface can be carried out by means of the screed arrangement in such a way that there are fewer health risks comes for the operator.
  • the invention relates to a screed assembly for installation of a paving, said screed assembly seen in the working direction determines a working width for the installation of the pavement and has a workplace for an operator, the workplace is vibration-decoupled mounted on the screed assembly, so that transmission of vibrations of the screed assembly can be reduced or prevented in the workplace.
  • the operating staff can therefore spend a long time comfortably on the workstation to observe the installation from there and control if necessary, without causing health risks for the operating personnel.
  • the vibration-decoupled workplace provides a secure location on the screed assembly where sensitive equipment, such as gauges, can be stored and stored. Vibrations are speed-dependent oscillations by moving components of the screed arrangement as well as impacts, leveling movements or other adjusting movements of the screed arrangement.
  • the workplace is attached to a side slide of the screed assembly to be associated with an outer region of the working width.
  • the side slider is an especially mechanically or hydraulically (height) adjustable unit, which is attached to the lateral boundary of the working width respectively at outer ends of the screed assembly. Since in most screed arrangements, the basic structure of the respective sideshift is substantially the same, regardless of whether it is a rigid screed assembly, a screed assembly with broadening parts or a screed assembly with pull-out parts, the workplace and its attachment to the side shifter could be screed uniform across types, which leads to cost savings in production.
  • the outer area of a freshly installed pavement can be well seen, which is particularly advantageous in impact-to-collision work, i.e. when pavements are made parallel to each other.
  • numerous control functions of the screed assembly can be well controlled from this point. For example, from there an operating unit, which is fastened laterally to the screed arrangement, primarily on the side slide, can be controlled in order to set, for example, temperatures at components or vibration speeds of compressor components of the screed arrangement.
  • the workstation is fastened to a side slide carrier of the side slide, for example flanged or welded on.
  • the side slider support extends substantially horizontally along lateral ends of the ball assembly, with a height-adjustable side slider sheet being supported inwardly of the screed assembly.
  • the side slide carrier forms a sturdy base for attaching the workstation.
  • the attachment of the workplace on the side slide carrier has the significant advantage that it can be structurally identical in all screed types, and that the natural vibration behavior of the side sill regardless of the set working width of the screed assembly is essentially immutable, so that the vibration isolation of the workplace at this point particularly reliable can be guaranteed and can be adjusted well.
  • the workplace comprises a fastening unit, by means of which it is preferably fastened detachably to the screed arrangement, in particular the side slider support.
  • the mounting unit also allows the workstation to be retrofitted to a screed assembly of any type, and that the workstation can arbitrarily switch between different screed types.
  • the fastening unit comprises a vibration decoupling unit.
  • the thus vibration-decoupled workstation therefore provides a place for the operating personnel, where it is longer Spend time, for example, over eight hours, without taking health-related risks.
  • the vibration decoupling unit comprises at least one mass-spring system and / or a shock absorber.
  • the mass-spring system in particular, can keep away from the workplace speed-related vibrations of movable components of the screed assembly, which leads to a quiet position or seat of the operating personnel on the workstation.
  • the shock absorber can dampen shocks that may occur, for example, when starting the paver, when crossing bumps or when leveling the screed assembly.
  • the shock absorber of the vibration decoupling unit is automatically reversibly adjustable in order to bring the workplace always in a desired starting position.
  • this is a closed liquid spring, which, so to speak, is easy to install and to maintain as a closed unit.
  • a hydraulic shock absorber would be used, which is connected to an existing hydraulic system of the screed assembly. Expedient, in particular cost-effective, however, is also the use of a mechanical shock absorber and / or a gas pressure shock absorber.
  • the mass-spring system can be biased between the workstation and the screed assembly to thereby set a desired hardness therein.
  • the degree of hardness of the mass-spring system can thereby be individually adapted to different heavy operators.
  • the vibration decoupling unit is particularly user-friendly when a preload force of the mass-spring system can be set manually and / or automatically.
  • a manual adjustment could be realized, for example, by a screw design, by means of which the workstation is screwed against the natural extension of the mass-spring system.
  • An automated solution could include, for example, an electric motor as a drive, which presses the workplace to a desired biasing force against the expansion of the mass-spring system by its activation. It would also be conceivable to functionally couple the operation of the electric motor to a weight detection system, wherein the electric motor controls the preload force on the mass-spring system automatically in response to a detected weight of the operator located on the workstation.
  • the shock absorber has a variable damping hardness. This could be realized, for example, by adjusting the displacement volume of a damper fluid per unit of time. Similar to the mass-spring system, the damping hardness could also be manually and / or automatically adjustable to allow the operator a maximum individualization of the workplace.
  • the fastening unit comprises a swinging bearing, which is mounted on the screed assembly and the workplace hingedly coupled thereto, wherein the workplace is movable by means of the swing bearing between a stowage position and a working position is particularly advantageous. Depending on requirements, this can be used to fold out the workplace or, in particular, to bring it into the stowed position for transporting the screed assembly. It is also useful if the screed assembly in addition to the workplace has a catwalk for the operator on which the operator can also cross the working width during installation behind the screed assembly.
  • the workstation comprises a preferably height-adjustable floor panel on which the operator can stand safely, the walkway extending along a greater range of the working width of the screed assembly than the floorboard of the workstation.
  • the bottom plate seen in the direction of work to a greater depth than the catwalk, so that the operator can stay on it safely for a long time.
  • the bottom plate is arranged substantially at the same height as the catwalk. Seen from the rear, the floorboard of the workplace looks like an extension of the catwalk.
  • the bottom plate could also be arranged at a higher level than the catwalk, which may result in better Einsehdes in the installation and the screed assembly for the operator located on the workstation.
  • a particularly compact embodiment of the invention provides that the bottom plate is arranged in alignment with the catwalk, ie, that the bottom plate in series with the Catwalk is arranged and substantially the same depth as the catwalk comprises. This may be particularly advantageous for the transport of the screed assembly, because the bottom plate of the workplace does not protrude further back than the catwalk. In addition, particularly few edges and corners between the bottom plate and the catwalk are formed, which could trigger the operator.
  • the workplace can be set up particularly conveniently for the operator when the workplace comprises a seat, in particular a height-adjustable seat.
  • the comfort could be further increased by the air-suspension of the seat.
  • the workplace For use in bad weather, the workplace is particularly well if it is equipped with a weather roof.
  • the weather roof also acts as a shade dispenser, so that the operator is not exposed to the blazing sun on the workplace in fine weather.
  • a control unit for controlling functions of the workstation for example, the height adjustment of the bottom plate and / or the respective degrees of hardness of the mass-spring system and / or the shock absorber, and / or the screed assembly is installed on the workplace.
  • the vibration-decoupled workplace provides a safe place for storage and trouble-free operation of the sensitive and expensive operating unit.
  • Warning signals can also be output by the operating unit in order to warn the operator on the paver or to indicate to the operator that he should change a parameter of the installation run, for example a delivery volume of the deposit.
  • the operating unit can also have a display on which current setting parameters of the screed arrangement can be displayed.
  • the operating unit provided on the workstation can be functionally connected to an electronic measuring unit which is fastened to the screed arrangement or directly to the workstation.
  • the measuring unit can be designed, for example, to measure a distance to the ground, ie to the ground on which the paver travels, to the side of the screed arrangement. With regard to this distance, for example, the leveling of the screed assembly can be automated or a layer thickness of the newly laid road surface can be calculated. If the measuring unit is mounted on the vibration-decoupled workstation, then the measurement result could be improved. In addition, no harmful shocks would be transmitted to the measuring unit there. It is also expedient if a collision protection unit is arranged on the workstation which can be used to record objects approaching the workstation.
  • the collision protection unit can be configured such that it determines the distance from a workstation to a rolling vehicle traveling behind, and that as soon as it approaches too close to the workstation, it issues warning signals itself or via the optionally connected control unit. These signals can be formed either acoustically or visually.
  • the workplace is then designed for the operator, if he also has a suction unit, which is designed for the extraction of vapors of the road surface to be incorporated.
  • the suction unit can either be designed independently or connected to a suction unit already assigned to the screed arrangement.
  • the suction unit is designed such that it directs the ascending vapors under the floor panel to the rear behind the workstation and / or collects the rising vapors and this promotes via a planned exhaust pipe over the roof of the paver and / or the workplace.
  • the workplace includes a lighting unit, primarily to illuminate the workplace itself and the outer area of the working width.
  • the lighting unit helps the operator in particular when entering or leaving the workplace and to control the control unit.
  • the workplace can be made even more comfortable by having an air conditioning unit, in particular a heating and / or cooling unit formed thereon. This allows the operator to cool or heat the workplace depending on the weather.
  • the above-mentioned seat of the workplace is tempered with it.
  • the workplace or at least its essential structure is releasably secured to the screed assembly so that it can be removed overnight from the screed assembly. can be used to protect the units installed thereon, for example the operating unit or the measuring unit, against theft.
