Definitions

  • the invention relates to a slipform paver with a height-adjustable machine frame and an assembly unit arranged on the machine frame for fastening a concrete trough.
  • the invention relates to a slipform paver with a concrete trough.
  • the slipform pavers With the known slipform pavers, components made of a flowable material, in particular concrete, can be manufactured continuously.
  • the slipform pavers have a device in which the flowable material is brought into the desired shape.
  • Such a device for shaping the flowable material is also referred to as a concrete trough.
  • the concrete troughs To produce components with different cross sections, the concrete troughs must be replaced. Therefore, the known slipform pavers have an assembly unit to which concrete troughs of different designs can be attached.
  • the machine frame of the known slipform pavers is connected to chain drives via lifting columns.
  • the height of the machine frame can be adjusted by retracting or extending the lifting columns.
  • the machine frame can be raised or lowered on the left or right side in the working direction and / or raised or lowered on the front and rear side in the working direction. Since the concrete trough is firmly connected to the machine frame, the orientation of the machine frame also determines the orientation of the concrete trough.
  • the US-A-6 109 825 describes a slipform paver with a concrete trough, the machine frame of which can be adjusted in height on lifting columns.
  • the EP 1 264 943 A2 describes a slipform paver which has a height-adjustable machine frame and a drive unit with drive means for executing translatory and / or rotary movements.
  • the slipform paver has different working units. These work units each comprise components which are fixed immovably or pivotably on the side parts of the machine frame.
  • the components of a work unit form the upper part of a mold for concrete.
  • the profile of the concrete part to be manufactured can be changed.
  • the two components are inclined.
  • the concrete form is made up of various parts that are connected to the machine frame.
  • a construction machine for lining a trench which has a side frame which is pivotally attached to the machine frame of the construction machine.
  • the side frame comprises a concrete mold for producing a trench lining.
  • the frame consists of a number of rigid tubular members welded together in a substantially rectangular configuration. The pivotable attachment of the side frame to the machine frame only serves to align the frame with respect to the inclination of the trench (slope).
  • a construction machine for lining a trench which has a side frame pivotably attached to the machine frame of the construction machine, is also from the GB 1 513 615 A. known.
  • the US 3,625,121 A describes an apparatus for producing layers of bitumen.
  • the device has a profiled guide plate and a drag plate, which are used to produce a layer of bitumen.
  • the guide plate is pivotally attached to another plate.
  • a mechanism is provided for adjusting or adjusting the angular position of the guide plate.
  • the known slipform pavers allow the production of components with an orientation that changes continuously along their length. The contour or cross-section of the components also changes continuously over the length if one assumes that the floor on which the component is to be built is level.
  • water channels can be produced which, among other things, have an inner flank facing the traffic route and the inclination of which continuously changes along the traffic route. In the area of the processes, the inner flank lies in the level of the traffic route, while the flank between the processes is inclined inwards with respect to the traffic route. The flank can have the greatest slope halfway between the processes.
  • the invention has for its object to provide a slipform paver which allows in particular an improvement in the working conditions for the machine operator.
  • the slipform paver according to the invention has a drive unit with drive means for executing translatory and / or rotary movements and a control unit which is designed in such a way that the drive means of the drive unit are controlled to carry out the translatory and / or rotary movements.
  • the drive means of the drive unit can include the known chain drives and lifting columns.
  • the slipform paver according to the invention is characterized in that the assembly unit for fastening a concrete trough is pivotally mounted on the machine frame about an axis running in the working direction of the slipform paver.
  • the slipform paver has a swivel unit which has drive means for swiveling the assembly unit about the swivel axis running in the working direction.
  • the concrete trough fastened to the assembly unit is pivoted about the pivot axis by means of the pivot unit, while the machine frame maintains its orientation.
  • the manufacture of the component does not require a change in the orientation of the machine frame. Since the machine frame maintains its orientation, the working conditions for the machine operator are improved.
  • there is less wear on the lifting columns since the lifting columns do not have to be retracted or extended.
  • an undesired inclination of the conveyor belt of the conveyor for loading the concrete trough with concrete is avoided.
  • the assembly unit for fastening the concrete trough is understood in particular to mean a unit with which concrete troughs of different designs can be exchanged quickly. Such changing devices for concrete troughs are known to the person skilled in the art.
  • An assembly unit can also be understood to mean a unit that does not allow the concrete trough to be changed quickly. In principle, the concrete trough can also be connected to the machine frame without being able to be replaced.
  • the drive means of the swivel unit are preferably operated by the central control unit of the Controlled slipform paver, with which the drive means of the drive unit for controlling the translatory and / or rotary movements are also controlled.
  • a preferred embodiment provides that the drive means of the swivel unit for executing the swivel movements are controlled according to a predetermined movement sequence in order to give the components to be manufactured the desired shape.
  • the specified movement sequence comprises a pivoting movement of the assembly unit about the pivot axis running in the working direction of the slipform paver from a neutral position, which can correspond to a horizontal or essentially horizontal orientation of the concrete trough, into an inclined position and from the inclined position back into the neutral position.
  • the predetermined movement sequence can also include a sequence of such pivoting movements. This allows water channels to be produced whose flanks facing the traffic route are inclined between the drains and are not inclined at the drains.
  • control unit provides that the individual pivoting movements resulting from the pivoting movements are carried out within a time interval in which the slipform paver has traveled a predetermined distance.
  • the specified distance between the individual swiveling movements can correspond to the intervals between the processes on the water channels.
  • the drive means of the swivel unit can be designed differently.
  • the swivel unit can have, for example, hydraulic and / or pneumatic and / or electromotive drive means.
  • the swivel unit preferably has hydraulic drive means.
  • the assembly unit has fastening means which interact with complementary fastening means of an assembly unit of a concrete trough in order to be able to replace the concrete trough.
  • the fastening means are preferably on one Arranged mounting plate of the mounting unit, which is pivotally mounted about an axis running in the working direction of the slipform paver, the drive means of the pivot unit engaging the mounting plate.
  • the assembly unit can also be arranged on the machine frame so as to be adjustable in height and / or along an axis transverse to the working direction of the slipform paver, in order to move the assembly unit or the concrete trough independently of the pivoting movements can.
  • a preferred embodiment of the control unit provides that a device for adjusting the assembly unit can be controlled along an axis running transversely to the working direction of the slipform paver and / or for adjusting the height of the assembly unit.
  • control unit further provides that the control unit is designed such that any reference point of the concrete trough maintains a constant horizontal and / or vertical distance from a reference by adjusting the assembly unit. This allows deviations from the desired horizontal and / or vertical distance, which are caused by the pivoting of the mounting unit, to be compensated. As a result, the concrete trough swings around an axis of this arbitrary reference point that runs in the working direction of the slipform paver.
  • Fig. 1 shows the slipform paver in the rear view. Since slipform pavers as such are part of the prior art, only the components of the construction machine that are essential to the invention are described here.
  • the slipform paver 1 has a machine frame 2 which is supported by a chassis.
  • the undercarriage has a front left and a working direction rear left chain drive 4A in the working direction of the slipform paver and a right and working right rear chain drive 4B in the working direction, which are attached to front and rear left lifting columns 5A and to front and rear right lifting columns 5B are.
  • the working direction of the slipform paver points to the drawing level.
  • the chain drives 4A, 4B and lifting columns 5A, 5B form the drive means of a drive unit 3 for executing translatory and / or rotary movements of the slipform paver.
  • the machine frame 2 can be adjusted in height relative to the floor.
  • the machine frame 2 can be inclined in different directions with respect to the ground.
  • the construction machine can be moved in different directions.
  • the drive means 4A, 4B, 5A, 5B of the drive unit 3 are used to perform the translatory and / or rotary movements of one in Fig. 1 controlled central control unit, not shown.
  • the control unit controls the drive means in such a way that the slipform paver follows a guide wire 6 stretched in the working direction.
  • the slipform paver can also follow another reference that may already be present in the field, for example a curb or a guide wall.
  • the slipform paver has a scanning device 7, which is only indicated, with a horizontal and a vertical scanning element 7A, 7B, which scan the guide wire 6 in the horizontal and vertical directions.
  • a slipform paver with such a scanning device is from, for example US-A-4 041 623 known.
  • the slipform paver has a concrete trough 8.
  • the exchangeable concrete trough 8 is detachably fastened to the machine frame 2 on the left side of the slipform paver in the working direction with a quick-change system 9.
  • the concrete trough 8 has a chute 8A, which is used to supply concrete with a conveyor device of the slipform paver, not shown, and a shape 8B arranged below the chute, which is delimited by side plates 8C, 8D.
  • the trough quick-change system 9 has an assembly unit 10 assigned to the machine frame 2 and an assembly unit 11 assigned to the concrete trough 8.
  • the assembly unit 10 of the machine frame 2 and the assembly unit 11 of the concrete trough 8 each have a mounting plate 10A or 11A, on each of which fastening means 10B or 11B are arranged, which engage with one another when the concrete trough is locked on the machine frame 2.

  • the assembly unit 10 of the slipform paver can be adjusted on the machine frame 2 with a device 12 both in height and along an axis running transversely to the working direction.
  • the lateral adjustment is carried out by means of a horizontal piston cylinder arrangement 12A and the height adjustment by means of a vertical piston cylinder arrangement 12B.
  • the concrete trough can thus be moved in such a way that an arbitrarily selectable reference point (R) of the concrete trough maintains a constant horizontal distance (h) and / or a constant vertical distance (v) from the guide wire 6.
  • R reference point
  • v constant vertical distance
  • the slipform paver is used in particular for the continuous production of components, the orientation of which continuously changes in the working direction.
  • This includes in particular water channels 13 which have an inner flank 13A facing the traffic route and an outer flank 13B facing away from the traffic route.

  • Fig. 1 shows the neutral position, in which the concrete trough 8 is not pivoted.
  • the concrete trough is in the in Fig. 2 shown inclination, while the concrete trough in the Fig. 3 shown inclination when the piston is fully extended.
  • the concrete trough can also assume all other intermediate positions.
  • the inner flank of the shape 8B of the concrete trough 8 has a lower inclination than in that in Fig. 3 shown inclination.
  • the piston-cylinder arrangement 15C of the swivel unit 15 is controlled by the central control unit of the slipform paver.
  • the central control unit is designed such that a specific movement sequence can be specified for the pivoting movement of the assembly unit 10.
