Definitions

  • the invention relates to a slipform paver according to the preamble of claim 1 and a method for adjusting the width of a tray device of a slipform paver according to the preamble of claim 15.
  • slipform pavers serve to produce paving concrete.
  • Known slipform pavers have a tractor, which may also be referred to as a base machine or carrier machine and consists of a machine frame and four drives, the tractor carries different working facilities for producing a concrete roadway, wherein for forming the concrete extending across the roadway Concrete tray is used.
  • slipform pavers have already been developed whose machine frame can be telescopically adjusted ( WO 2002/101150 . WO 99/50503 ).
  • the rigidity of the depression element is impaired by the division of an intermediate element into several segments and thus also the moment of resistance of the entire depression device in the working direction, as well as in the direction of gravity.
  • the present invention seeks to further develop a slipform paver of the type mentioned and a method for adjusting the width of the concrete trough of a slipform paver to a modified working width such that the apparative Effort and changeover times are reduced, and the moment of resistance of the concrete trough of the slipform paver is increased.
  • the invention provides in an advantageous manner that the permanent outer trough element is fixedly secured to one of the cross member and / or one of the longitudinal members, and that the outer trough element with the working width adjustment of the machine frame is movable.
  • all trough elements can be compressed via the working width adjustment until they rest against one another.
  • the working width adjustment can take place with the aid of substantially parallel to the trough device or orthogonal to the direction of aligned drives, wherein a divergence of the machine frame can also be done with a widening the track steering of the drives with or without hydraulic support by telescopic cylinder of the machine frame, without the drives must be aligned orthogonal to the working direction.
  • the depression device has at least one permanent central depression element, which is preferably arranged centrally relative to the base frame, and at least two permanent outer depression elements which can be moved relative to the base frame.
  • the insertable interchangeable tray elements of different widths can be completely and integrally suspended on a carrying device arranged above the tray elements, which connects all the tray elements arranged next to one another, no additional assembly work is required for the composition of the tray elements. Especially no flat resting on the ground support elements under the concrete trough is needed because the integral trough elements are merely suspended.
  • the support device forms together with the concrete trough a free and self-supporting construction.
  • the support means comprises support beams, which are guided longitudinally displaceably above the at least one central well element and are fixedly coupled to the outer well elements.
  • the support beams are preferably arranged in a double arrangement parallel to each other and can even be exchangeably fixed rigidly to the outer Muldenettin.
  • the trough device and the carrying device are divided into two, so that the central trough element has two articulated elements which are coupled to one another in the middle of the working width in order to form an adjustable roof profile, each of which is coupled via a carrying device to an outer trough element are.
  • the two halves of the trough device for adjusting a roof profile for the concrete layer to be created can be arranged roof-shaped, so that the concrete layer is increased in the middle of the roadway with respect to the edges.
  • the central trough element on the base frame and / or the outer trough elements on the cross member and / or the side member are height adjustable fastened.
  • the support beams of the split trough device each offset above the same, as well as in parallel and in the working direction to each other.
  • the support beams of the split trough device can thereby not collide with each other on the respective halves of the trough device with minimal working width adjustment in the region of the central trough element.
  • the drives can be pivoted at least at 90 ° at the ends of the longitudinal members.
  • the drives can be oriented on the one hand for the working operation in the working direction and for the transport operation, eg. B. can be aligned transversely to the direction of transport on trailers of a truck. In their position oriented transversely to the working direction, they are also suitable to accomplish the working width adjustment of the telescopic frame and thereby also to pull the outer trough elements according to the desired working width to the outside or to drive inwards.
  • the drives are preferably arranged at the lower end of lifting columns, which can be coupled via pivot arms with the longitudinal members.
  • the drives can be transferred either via the swivel arms or a steering of at least 90 °, or both ways in a desired position.
  • the support beams of the support means are fixed in place on the upper side of the permanent outer trough elements and are accommodated in the at least one central permanent trough element in each case arranged on the top of a sliding guide.
  • the arrangement on the top has the advantage that space is saved in the working direction of the slipform paver. This is important because the base frame and the tray means under the base frame in the working direction must not exceed a certain width when the slipform paver is transported on a truck.
  • the replaceable tray elements are slidably mounted on the carrying device after being suspended, as long as they are not locked with adjacent tray elements.
  • the individual tray elements may for example have a width between 10 cm and 200 cm.
  • the interchangeable tray elements are integral and are suspended as a one-piece element on the support means, so that no assembly work on the tray elements, apart from the mutual locking of adjacent tray elements themselves incurred.
  • the one-piece nature of the depression element is of particular advantage, since the depression element forms a closed profile in cross-section, so that a high resistance moment is formed against forces acting counter to the working direction and in the direction of gravity on the depression device. Also, and in particular the moment of resistance to torsion is significantly increased.
  • the trough device which is composed of such in cross-section a closed profile having trough elements, therefore, has a multiple of rigidity against Muidenettin, which are composed of several segments.
  • the slipform paver has a tractor 2, which consists of a machine frame 4 with extending parallel to the direction of longitudinal beams 8 and telescopic, transverse to the direction of cross beams 18 for variable adjustment of the working width.
  • the cross members 18 are in ( Fig. 2 ) or mounted on a base frame 20, wherein a total of four cross members 18 protrude from a arranged in the middle of the working width base frame 20 with variable length and are connected to the side rails 8.
  • the cross members 18 are offset from each other on or in the base frame 20, so that, for example, the working width between 3 m and 8 m can be varied.
  • the cross member 18 may also be multiply telescoped, if larger working widths should be adjustable.
  • the drives 14 can be pivoted at the ends of the side members 8 by an angle of at least 90 °, so that the slipform paver can be loaded transversely to its working direction on a low loader without exceeding the maximum allowable transport width.
  • Hubchulen 12 between the drives 14 and the machine frame 4 further allow height adjustment of the machine frame 4 in a known manner.
  • Fig. 2 shows a schematic, perspective view of the slipform paver according to the invention, wherein the base frame 20 carries a platform or cabin for the operator and drive means, which in Fig. 2 are summarized with the reference numeral 22.
  • the arrangement of telescopic Cross member 18 within the base frame can in principle Fig. 1 be removed.
  • Below the base frame 20 is as out Fig. 2 can be seen, a two-part trough device 28,32 (concrete trough) arranged, which extends over the entire working width, and the permanent trough elements 40a, 40b, 42a and 42b, and interchangeable trough elements 44, 46, 48, 50, the same or different widths can have.
  • the replaceable trough elements can for example have a width between ten centimeters and two meters, so that the width of the trough device 28, 32 can be adapted to any desired working width of the slipform paver.
  • the outer permanent well elements 42a, 42b are rigidly fixed either with the cross member 18 arranged above it at its end facing the longitudinal member 8, and / or on the longitudinal member 8 itself ( Fig. 3 ), so that when the drives 14 are in a position pivoted by 90 °, not only the working width of the machine frame 4 can be changed, but also the outer permanent tray elements 42a, 42b are pulled outward. This results in a distance from the central permanent well element 40a, 40b, so that the interchangeable well elements 44, 46, 48, 50 can be inserted into the resulting gap.
  • a self-supporting carrying device 54a, 54b is provided above the permanent tray elements 40a, 40b, 42a, 42b, which connects all tray elements 40 to 50.
  • All permanent or permanent and replaceable tray elements 40 to 50 can be locked with adjacent tray elements.
  • the replaceable trough elements 44 to 50 are displaceably mounted on the respective carrying device 54a, 54b after suspension, so that the trough elements 40 to 50, as long as they are not yet locked with adjacent trough elements, can be brought into a desired position, without further aids required are. In particular, no support means against the ground are required. This is an advantage, as there is rarely a level surface for the conversion of the slipform paver available on construction sites.
  • Each support means 54a, 54b has at least two mutually parallel support beams 56, 58 which abut on the outer permanent well element 42a and 42b, respectively, as in FIG Fig. 5c shown, are fixed.
  • the support beams 56, 58 preferably have a square or cuboidal cross-sectional profile and are each fixed in two transverse to the working direction side by side brackets 60, 61.
  • the pointing to the center of the slipform paver ends of the support beams 56, 58 are held on the central permanent well elements 40a, 40b respectively in sliding guides 64, 65.
  • the support beams 56,58 of a trough half 28 and the parallel support beams 56, 58 of the other half-hollow 32 offset in the working direction to each other, so that they can not collide with each other in the minimum working width adjustment.
  • the replaceable trough elements 44 to 50 have at their top two at least two offset in the direction of hooks 70, 71, which can overlap the support beam 56 and 58, so that the replaceable trough element 44 to 50 transversely slidably mounted on the support beams 56, 58 can be placed and precisely positioned in the working direction.
  • the hooks 70, 71 are bent in the working direction, can also be directed opposite. On the hooks 70, 71 may be provided a height adjustment, so that a fine adjustment of the height position of a replaceable trough element 40 to 50 is possible.
  • the division of the trough means 28, 32 makes it possible to set a roof profile preferably in the middle of the working width by the central trough elements 40a, 40b are hingedly connected at its lower edge and have at its upper edge a not shown in detail adjusting device for adjusting the angle of the roof profile ,
  • Fig. 6 shows the situation in which a relatively wide replaceable trough element 48 z. B. with the help of a lift truck in the gap between the permanent well element 40b and the interchangeable well element 50 is to be inserted.
