Definitions

  • the invention relates to a construction machine, in particular a road paver or a tandem roller.
  • Construction machines of this type are used, for example, in road and path construction, in the construction of squares and runways.
  • a construction machine typically comprises a machine frame, a driver's cab, at least one driving device, and an operating unit.
  • a construction machine of this type is a road paver or a tandem roller.
  • a road paver typically further comprises a material hopper positioned in front of the driver's cab in the paving direction, conveyor devices for the longitudinal and transverse conveyance of paving material, and a paving screed.
  • Tandem rollers typically have so-called roller drums as driving devices. Tandem rollers can be pivot-steered or articulated.
  • Such construction machines are usually self-propelled construction machines that have a drive motor, for example an internal combustion engine or an electric motor, which provides the drive energy required for operation of the construction machine.
  • the supporting structure of the construction machine is typically a machine frame and a chassis supporting the machine frame and having at least one driving device, for example a wheel, a track drive, or a compaction/rolling drum.
  • Construction machinery is typically operated from a control station on the construction machine.
  • the control station has suitable operating devices.
  • the control station can have at least one control station door.
  • the control station door can be adjustable, in particular pivotable, between a closed and an at least partially open position.
  • the control station door essentially represents a fall protection device and can, for example, be part of a railing structure. It can be provided that the control station must be entered through the control station door. This can be the case in particular with tandem rollers. However, it is also possible that opening the control station door is not necessary to enter the control station, as another access point is available, for example, from the rear of the construction machine, as is often the case with road pavers.
  • the control station can, for example, be open, have at least one roof arranged above the control station, or be designed in the form of a cabin that completely encloses the control station.
  • Road pavers are used to apply a surface layer of paving material, such as asphalt or concrete, to a prepared subsoil or to install.
  • paving material such as asphalt or concrete
  • they have a material hopper at their front end in which paving material is stored. This is transported through a central shaft to the rear of the machine and there distributed transversely to the working direction by a transverse distribution device, for example a screw conveyor. Finally, the paving material is smoothed off by a paving screed and pre-compacted.
  • a typical road paver for example, is in the DE102017002225A1 revealed.
  • Tandem rollers are usually used either to compact the subsoil on which a surface course is to be laid, or to compact a layer of paving material, in particular asphalt.
  • tandem rollers can be used in a paving train following a road paver in the paving direction and compact the asphalt mat laid out by the paver.
  • tandem rollers typically have two compaction drums, which can essentially consist of hollow metal cylinders with which the tandem roller rolls on the soil to be compacted.
  • at least one vibration exciter can be arranged, which causes the compaction drum to vibrate in order to influence the compaction.
  • a typical tandem roller can be found, for example, in the DE102018007825A1 revealed.
  • Construction machines of this type also have at least one control unit.
  • an control unit is understood to be a unit consisting of a driver's seat for the driver of the construction machine and the control elements used by the driver to control the construction machine.
  • the control elements can, for example, be part of a so-called control console.
  • An control console refers in particular to a type of panel-like arrangement of several control elements.
  • the driver's seat and the control console are typically movably mounted in the operator's station to allow the driver to adopt different seating positions within the operator's station. This can improve operating comfort and the driver's overview of the work area and the external environment of the construction machine, which increases both the accuracy of the work and operational safety.
  • control unit in this case also includes structures that connect the driver's seat to the control console or contribute to its movable mounting.
  • this also includes, for example, a support structure on which both the driver's seat and the control console are arranged. It is known to provide a transverse guide with at least one guide rail along which the control unit can be displaced.
  • the support structure can be movably mounted on the at least one guide rail, so that the support structure, together with the driver's seat and the control console, is designed to be movable along the at least one guide rail.
  • driver's seat and the control console it is known to design the driver's seat and the control console to be displaceable together in a direction transverse to the working direction of the construction machine within the operator's station.
  • a working direction In this case, this is understood in particular as a front/rear direction of the construction machine.
  • driver seats or control units that can be moved transversely to the working direction of the construction machine are known, for example, from the patents DE 10 2010 035 270 B4 and EP 1 961 607 B1 known to the applicant.
  • DE 10 2010 035 270 B4 discloses a driver's seat which, together with the control console and steering wheel, is mounted on a rail by means of a supporting structure and can be moved transversely.
  • US 2017/088103 A1 discloses a control station with a seat support on which a driver's seat and an operating console are arranged. Using the seat support, the driver's seat and the operating console can be moved together along a guide rail. The driver's seat is mounted so it can rotate around a vertical axis.
  • the driver's seat preferably has a so-called seat index point.
  • the seat index point is a standard defined in the EN ISO 5353 standard.
  • the EN ISO 5353 standard is hereby incorporated by reference.
  • the seat index point is determined using the determination device described in this standard.
  • the seat index point of the driver's seat is therefore approximately located at the intersection point of a theoretical axis of the upper body of a person sitting in the driver's seat with the theoretical axis of the thigh on the vertical plane passing through the seat centerline. It is therefore located in the middle of the seat, a few centimeters above the seat surface. Further details on the seat index point can be found in the aforementioned standard.
  • the seat index point represents a standard point for detecting a person sitting in a seat.
  • the seat index point can always be clearly located on every seat and in every position of the seat in accordance with the specifications of the standard, making it suitable for describing the position of the seat, particularly, for example, within the driver's cab and/or in relation to other elements.
  • the seat index point of this seat shall be considered to be a point located in the center of the seat surface and a few centimeters, in particular 5 cm, vertically above the seat surface.
  • the center of the seat surface is preferably the center point of a surface resulting from a projection of the driver's seat surface onto the horizontal plane.
  • the solution for a construction machine of this type is achieved by designing the support structure with the driver's seat and control console so that it can pivot about a vertical pivot axis, with the pivot axis being positioned in front of the driver's seat in the working direction.
  • the pivot axis refers to a movement axis and not necessarily a component axis.
  • the support structure together with the driver's seat and the control console, has a first degree of freedom, which is achieved by movement along the transverse guide or guide rail.
  • This movement is, in particular, a linear movement.
  • This movement preferably occurs horizontally and transversely to the working direction.
  • the term "horizontal” refers to a situation in which the construction machine is standing on a horizontally extending surface.
  • the transverse guide is designed in particular such that a corresponding movement of the support structure and the other components from a right side of the operator's station to a left side of the operator's station and vice versa is possible.
  • transverse displacement should therefore be possible, in particular starting from a first lateral displacement position in which the driver's seat is positioned entirely in a first half of the operator's station with respect to the width of the operator's station transversely to the forward direction of the construction machine, at least beyond the center line separating the width halves of the operator's station into the other or second half of the operator's station, such that the driver's seat is positioned entirely in the second half of the operator's station.
  • transverse displacement should be possible across the entire width of the interior of the operator's station, i.e. from the left side to the right side as seen in the working direction.
  • the support structure can be movable transversely to the working direction up to the side wall/railing that delimits the interior of the operator's station on the left or right side or, if this has an openable element, the operator's station door.
  • the support structure is adjustable in a horizontal plane transversely to the forward direction of the construction machine, i.e. in the direction of a width extension, at least with regard to the driver's seat, at least completely across the middle of the width extension of the operator's station from one side to the other side.
  • the support structure, the driver's seat and the control console can be moved, in particular linearly displaced, up to immediately next to the operator's station door.
  • the operator's platform of the construction machine has operator's platform doors on both sides, spaced apart transversely to the working direction
  • the supporting structure and the operator's seat as well as the control console can be connected along the transverse guide by a Position next to one operator's cab door to a position next to the other operator's cab door opposite in the direction of the width. It is therefore important that the range of adjustment in the width direction is not limited to a range of a few centimeters, as is known, for example, in terms of amount for individual adjustment of a seat height depending on body size or other individual factors of different operators.
  • the linear adjustability preferably covers a range of at least one meter, preferably of at least 1.5 meters, in the direction of the width.
  • the movement along the transverse guide takes place over almost the entire width of the operator's cab between a right-hand stop position, in which in particular the driver's seat, for example on its right-hand side, strikes against an adjustment travel limit formed in particular by a side limit positioned on the right-hand side of the operator's cab, and a left-hand stop position, in which in particular the driver's seat, for example on its left-hand side, strikes against an adjustment travel limit formed in particular by a side limit positioned on the left-hand side of the operator's cab.
  • driver's seat Preferably, only one driver's seat is provided on the operator's platform of the construction machine and/or on the entire construction machine.
  • prior art solutions provide multiple driver seats, for example, two driver seats spaced apart from each other transversely to the working direction. Due to the mobility of the driver's seat according to the invention transversely to the working direction along the transverse guide, the seat can be positioned on either side, eliminating the need for a second seat. This not only reduces production costs, but also simplifies operation of the vehicle.
  • a core idea of the present invention is to equip the support structure with the driver's seat and the control console with a further, second, degree of freedom. This is achieved by pivoting the support structure with the driver's seat and the control console around the vertical pivot axis. It is important that the support structure, the driver's seat, and the control console jointly perform exactly the same pivoting movement around exactly the same pivot axis, so that their relative position to one another ideally remains the same both during "displacement" according to the first degree of freedom and during "swivel” according to the second degree of freedom. Only the respective pivoting path of the aforementioned components differs due to a different distance from the pivot axis.
  • the pivot angle is exactly the same for all aforementioned components.
  • the pivoting movement occurs in particular relative to the transverse guide or the rest of the operator's station of the construction machine.
  • the pivot axis runs in the vertical direction (again, relative to a construction machine standing on a horizontal floor), so that the joint pivoting of the support structure, the driver's seat, and the control console involves a rotation in the horizontal plane.
  • the driver's seat can assume different positions within the operator's station (or, as explained in more detail below, even outside the operator's station) and/or can be aligned differently, particularly in relation to the construction machine or the working direction or straight-ahead direction of the construction machine.
  • the driver's seat can be tilted relative to the working direction so that the driver sitting in the driver's seat can more easily see one of the two sides of the construction machine.
  • the driver's seat can be tilted towards either side of the construction machine, i.e., with regard to the pivoting, either to the right or to the left.
  • the terms straight-ahead position and side position are also used below for positions of the driver's seat.
  • the driver's seat is in a straight-ahead position when the line of sight of a driver sitting in the driver's seat and looking straight forward is parallel to the working direction or the straight-ahead direction of the construction machine.
  • the driver's "straight forward” line of sight does not refer to the construction machine and its straight-ahead direction, but rather to the driver's seat.
  • a “straight forward” line of sight can also be derived from the arrangement of the seat, the backrest (if applicable), and the armrests of the driver's seat, in particular, for example, perpendicular to the vertical plane in which the backrest has its greatest extension, and from this plane toward the seat. Additionally or alternatively, the "straight forward" line of sight can be defined in a horizontal plane parallel to the greatest extension of the armrests' armrests. If this line of sight of the driver coincides with the straight-ahead direction of the construction machine, the driver's seat is in the straight-ahead position.
  • the driver's seat is in a lateral or inclined position. Because such lateral or inclined positions can be adjusted both to the right and to the left, the driver can choose from a variety of different positions and/or orientations of the driver's seat in the operator's station, depending on which position or orientation provides the best overview of work- and safety-relevant areas of the construction machine and/or its surroundings.
  • the fact that the driver's seat, together with the control console and the supporting structure that supports these two components, can be pivoted around the pivot axis ensures that the control console always has the same orientation relative to the driver's seat.
  • the pivot axis of the support structure can, in principle, run in various positions relative to the driver's seat, whereby, according to the invention, it is at least always arranged in front of the driver's seat in the working direction.
  • This relates to an arrangement or position of the pivot axis when the driver's seat is pivoted into a position in which a driver sitting on the driver's seat looks straight ahead in the forward direction of the construction machine.
  • a different movement of the driver's seat and the control console results during the pivoting process.
  • the pivot axis runs in the working direction of the construction machine between the driver's seat and the control console.
  • the control console is preferably located in the working direction in front of the driver's seat.
  • the control console would be pivoted in a different direction transverse to the working direction than the driver's seat when pivoted about the pivot axis.
  • the control console would, for example, be pivoted to the left transverse to the working direction and the driver's seat to the right transverse to the working direction, or vice versa.
  • the swivel axis and the control console are positioned or run in front of the driver's seat on the support structure in the working direction. This allows the driver's seat to cover a greater swivel range when pivoting around the swivel axis than the control console, albeit in the same direction. This allows the driver's seat to assume more pronounced lateral positions by pivoting around the swivel axis, thus allowing the driver a viewing angle that differs significantly from the straight-ahead position.
  • the pivot axis is preferably functionally the only pivot axis about which the support structure with the driver's seat and the control console can be pivoted.
  • the support structure together with the other components, is designed to be pivotable exclusively about the said pivot axis.
  • separate axes of rotation can be provided, for example the driver's seat can be rotated independently of the support structure and the control console, for example about a vertical axis.
  • the control console can also be designed to be rotatable independently of the support structure and the driver's seat about an axis, in particular a vertical axis, for example in order to provide individual adjustment options for different drivers.
  • pivot axis is not a physical component, but rather a virtual reference axis that characterizes the rotational movement and is specified or defined, in particular, by an articulated mounting of the support structure on the transverse guide.
  • the transverse guide generally refers to all components that contribute to the mounting of the support structure, and thus also of the driver's seat and the control console, with the described mobility along the transverse guide, in particular horizontally and transversely to the working direction of the construction machine.
  • the transverse guide preferably comprises, for example, in addition to the guide rail, at least one transverse guide support via which the guide rail is arranged in the operator's station. It is ideal if the transverse guide has at least and very particularly precisely two transverse guide supports, in particular projecting vertically, which are arranged at the respective ends of the guide rail and mount it in the operator's station.
  • the transverse guide supports can thus be designed in the form of spars and preferably form a frame or supporting frame for the guide rail.
  • the transverse guide supports are connected directly to the machine frame. It is preferred if the transverse guide supports are connected to a base structure forming the supporting structure of the operator's station, which base structure is mounted on the machine frame, in particular in a vibration-damped manner.
  • the transverse guide and the guide rail are preferably located in front of the driver's seat and/or the support structure and/or the control console in the working direction.

  • the guide rail has a non-circular, in particular square or polygonal, cross-section in order to prevent rotation of the support structure about the longitudinal axis of the guide rail.
  • the transverse guide in addition to the guide rail, has a further bearing rail arranged at a vertical distance from the guide rail.
  • the bearing rail preferably also runs parallel to the guide rail with respect to its longitudinal extent.

  • the guide rail bears a large part of the weight of the support structure, the driver's seat and the control console. In this way, the bearing rail can be less massive than the guide rail.
  • the guide rail can be designed with a round cross-section and the support structure can be mounted on the guide rail, for example via the sliding bushing using ball bearings. This enables particularly simple and smooth movement of the support structure along the transverse guide. This can therefore be achieved solely by the muscle power of the driver himself, without the need for additional propulsion, and without being perceived as unpleasant by the driver.
  • the support structure is mounted on the transverse guide via a support carriage.
  • the support structure is preferably mounted on the support carriage via a pivot joint forming the pivot axis.
  • the support carriage is thus mounted, for example, via the aforementioned sliding bushing or a similar movable bearing device on the guide rail along the transverse guide.
  • the support carriage can have a further sliding bushing with which it is mounted on the bearing rail so that it can move along the transverse guide.

  • it is particularly easy for him to look past another vehicle on the construction site, for example a truck driving in front of or behind the construction machine 1.
  • the usual communication with the driver of this other vehicle on the construction site is also facilitated.
  • he can also look along the outer contour of the machine and, for example, determine with high precision where the construction machine 1 is traveling and which parts of the ground are therefore being worked by it and which are not. Distances to obstacles can also be determined particularly precisely in this way.
  • the driver can open the cab door 26 manually.
  • a coupling device 35 ( Figure 3 ) may be provided, which leads to an automatic opening of the operator's cab door 26 when the support structure 30 is pivoted about the pivot axis S in one of the end positions of the transverse guide 31 onto the operator's cab door 26.
  • the coupling device 35 can, for example, be a stop that pushes the operator's cab door 26 open outwards.
  • the coupling device 35 can also comprise a magnet, so that the operator's cab door 26 can also be automatically closed by the coupling device 35 when the support structure 30 and the driver's seat 8 as well as the control console 9 are pivoted from the pivoted-out position back into the straight-ahead position.
  • a pivoting floor 27 is preferably provided. This preferably has the shape of a circular sector and is pivotable about a pivot axis, in particular between a storage position and a working position.
  • the pivot axis of the pivoting floor 27 is preferably coaxial with a door rotation axis T ( Figure 8 ), wherein the pivot axis of the pivoting floor 27 is also preferably arranged at the tip of the circular sector.
  • the pivoting floor 27 is preferably arranged in a storage compartment under the operator's cab floor 28 and can be pulled out from there into a working position, in which the pivoting floor 27 preferably bridges or closes the area between the operator's cab floor 28 and the open operator's cab door 26 in the horizontal plane.
  • the pivoting floor 27 thus extends the operator's cab floor 28 when the operator's cab door 26 is open, extends beyond the actual extent of the operator's cab floor 28 and therefore secures the driver, who is no longer above the operator's cab floor 28 when the operator's seat 8 is in the swiveled-out position.
  • the operator's seat 8 is then arranged above the swivel floor 27 in the working position.
  • Figure 8 shows that the displacement direction h of the support structure 30 with the control console 9 and the driver's seat 8 runs transversely to the working direction a.
  • pivoting of the support structure 30 or the control console 9 and the driver's seat 8 about the pivot axis S is preferably characterized by a pivot angle W, which is spanned by two vertical planes, each of which runs through the seat index point SIP of the driver's seat 8 and the pivot axis S.
  • One vertical plane results from the straight-ahead position of the driver's seat 8 before pivoting about the pivot axis S and the second vertical plane results from the lateral position of the driver's seat 8 after pivoting about the pivot axis S.
  • the pivot angle W measured in the horizontal plane results. The larger the pivot angle W, the further the driver's seat 8 and its seat index point SIP can be pivoted outwards.
  • Figure 8 It is also apparent that the operator's cab door 26 can be opened or closed about a door rotation axis T.
  • the door rotation axis T is preferably arranged in the working direction a in front of the pivot axis S.
  • the door rotation axis T is arranged by an offset v in the working direction a in front of the pivot axis S. In this way, it is ensured that pivoting of the support structure 30 and in particular of the control console 9 about the pivot axis S is possible even in the end positions predetermined by the transverse guide 31.
  • the control console 9 would be positioned with its left rear corner, which is in Figure 8 protrudes beyond the outer contour of the construction machine 1, collide with the operator's cab door 26. Due to the correspondingly preferred arrangement of the door rotation axis T in the working direction a in front of the pivot axis S, sufficient space is provided in this area so that the operating console 9 can also pivot freely into the lateral position.
  • Figure 8 It also shows that the seat index point SIP of the driver's seat 8 can preferably be pivoted outwards beyond an outer contour K of the construction machine 1.
  • the outer contour K of the construction machine 1 is defined by the outer surface of the construction machine 1 and in particular of the operator's station 2 when the operator's station door 26 is closed. the area in which the closed operator's cab door 26 is arranged, the outer contour K of the construction machine 1 is therefore defined by the position of the outer surface of the closed operator's cab door 26.
  • the outer contour K of the construction machine 1 remains as a virtual reference surface in the same position in which it is located when the operator's cab door 26 is closed, even when the operator's cab door 26 is open.
  • the driver's seat 8 and in particular also the seat index point SIP of the driver's seat 8 are pivoted outwards beyond this outer contour K by pivoting the support structure 30 about the pivot axis S.
  • the seat index point SIP is in particular moved beyond the outer contour K in such a way that it has a distance d to the outer contour K.
  • the distance d is measured in particular in the direction transverse to the working direction a.
  • Figure 9 shows that pivoting of the support structure 30 with the driver's seat 8 and the control console 9 around the pivot axis S is also possible in a position along the transverse guide 31 which is not an end position.
  • the driver's seat 8 is located entirely within the operator's station 2, even though it is in a lateral position, i.e., pivoted about the pivot axis S.
  • This also allows the driver to adopt different positions and different orientations of the driver's seat within the operator's station, thus improving his overview of the construction machine 1 and the work process.
  • the invention therefore makes it possible to significantly improve the flexibility of an operating unit 29 of a generic construction machine 1 and thus increase work safety and work quality.
