Definitions

  • the invention relates to a slipform paver with a pre-scraper mounted vertically adjustable on a frame, a pressure plate spaced from it and forming an upper slide formwork, and a vibrating device in the intermediate area.
  • a slipform paver of this type is known from DE-A-30 32495.
  • the level of paving material in the area between the scraper and the pressure plate must be kept within relatively narrow limits of, for example, ⁇ 2 cm around a target value of, for example, 5 cm above the underside of the pressure plate. If the level is too low, the pressure plate cuts into the liquid slurry area too much, so that accordingly less installation material gets under the pressure plate, which can result in corresponding imperfections, in particular holes, in the concrete ceiling. In addition, the top layer of the pavement produced in this way has lower strength and tends to dry out. If the level of the paving material in this area is too high, the pressure plate cuts into the concrete material too far below the approx.
  • Constant thick slurry layer given the concrete moisture The result is that the concrete material under the pressure plate is too dry, so that a flat, smooth road surface can no longer be achieved.
  • an upper concrete layer is placed on the lower concrete layer applied first. During the production of this upper concrete layer, a slurry layer of reduced thickness is created in the area between the preliminary scraper and the pressure plate due to the smaller concrete volume. The correspondingly more precise level regulation cannot always be achieved manually.
  • a slipform paver without a scraper in which the pressure plate following the vibrating device, which forms an upper slipform, is formed by a rubber apron which is supported on a height-adjustable crossbeam and on a sensor plate following the crossbeam .
  • This arrangement prevents that if the installation material pressure below the rubber apron is too high, it will boil up after the rubber apron has passed. If the installation material pressure is too high, the sensor plate hinged to the frame is pivoted upward from the apron, whereupon a control device is actuated which controls a height adjustment drive for the crossbar in the direction of a reduction in the excess pressure, that is to say by correspondingly lowering the crossbar.
  • the object of the invention is to provide a slipform paver of the type mentioned at the outset with improved manufacturing quality and simplified operation due to automatic regulation of the scraper height.
  • a sludge level sensor in the area between the scraper and pressure plate for the installation material, a height adjustment drive for the scraper and a control device which compares a determined actual sludge level with a desired sludge level and in the direction a reduction in the level difference that controls the height adjustment drive are provided.
  • control device comprises a three-point switch which can be actuated by the level sensor, with the switch positions "neutral position”, "raise the preliminary scraper” and “lower the preliminary scraper”.
  • a follow-up control is preferably provided with different target level values that can be entered manually.
  • a float arrangement which directly indicates the sludge level is preferably used as the level sensor.
  • the floating body arrangement comprises a floating body and a connecting link carrying the floating body at one end and articulated at the other end to the scraper, and that the connecting link between the articulation point and the floating body is connected to a measuring rod which is connected to the three-point switch attached to the frame is coupled.
  • a sludge level change immediately leads to a lifting or lowering of the floating body and subsequently to a pivoting movement of the connecting link, which is transmitted directly via the measuring rod to the three-point switch.
  • the pre-scraper height can be adjusted accordingly quickly and precisely. Since the level sensor is now articulated on the scraper, the height adjustment of the articulation point is not necessary when the target level of the scraper is changed.
  • connection point between the connecting link and the measuring rod a distance from the articulation point between 1/4 and 1/3, better 1/3 to 2/3, ideally about half the distance between the articulation point and the center of buoyancy of the preferably spherical or cylindrical float.
  • the floating body is preferably spherical or cylindrical, with the advantage of simple manufacture and mechanical robustness.
  • a switch actuating element for the three-point switch which can be optionally attached to the measuring rod in various positions along the measuring rod, is provided, which enables simple and quick adjustment or readjustment of the desired level.
  • the switch actuating element is articulated to a switching lever of the three-point switch, and that the switch actuating element engages around the measuring rod and can be fixed on the measuring rod by means of a locking screw.
  • the height adjustment drive comprises at least one preferably double-acting hydraulic cylinder.
  • the hydraulic cylinder preferably engages the pre-scraper via a double-arm lever articulated on the pressure plate.
  • the optimal height difference between the preliminary scraper and the pressure plate is essentially independent of the height of the pressure plate.
  • the permissible swivel range of the double-arm lever articulated on the pressure plate can therefore be in a constant small range even with widely differing pressure plate heights.
  • the three-point switch directly controls a corresponding hydraulic device for the at least one hydraulic cylinder.
  • an electrical control circuit is preferably provided, which is connected to the electromechanical three-point switch and controls a hydraulic device connected to the at least one hydraulic cylinder. Such a control circuit can be changed more easily if it functions reliably, in particular with regard to its control properties.
  • the formation is designated 10.
  • a one- or two-layer concrete pavement 12 is to be erected on this level.
  • auxiliary banquets 14 are first built on both sides of the longitudinal edges thereof, as indicated in FIG. 1.
  • slipform paver can also run in a conventional manner on rails which rest directly on the formation.
  • the slipform paver 16 comprises two crawler tracks 18 on the side for driving on the auxiliary banquets 14 or on stationary formwork and running rails 44 placed thereon.
  • the crawler tracks 18 are equipped with rubber studs 20.
  • a distributor 22 for the paving material 24 is arranged at the front end of the slipform paver 16, this distributor 22 executing a reciprocating movement perpendicular to the plane of the drawing in FIG. 1.
  • the slipform paver 16 comprises a slipform consisting of a horizontal pressure plate 26 and vertical side formwork, which can also be omitted when using the formwork and running rails 44.
  • vibrating elements in the form of so-called vibrating bottles 30 are distributed over the width of the resulting roadway surface 12 and are immersed in the installation material 24 distributed by the distributor 22.
  • a preliminary scraper 32 is arranged between the scraper bottles 30 and the distributor 22, a preliminary scraper 32 is arranged. As will be explained in more detail below, the height of the preliminary scraper 32 is regulated automatically.
  • the preliminary scraper 32 is rigidly attached to one end of a bent double-arm lever 49, which is articulated on the vertical front wall 26a of the pressure plate 26 in the kink area and can be pivoted about a horizontal pivot axis 54 via a hydraulic cylinder 50, the piston rod 52a of which engages the other lever end.
  • a dowel setting device 34 is arranged at the rear end, which can be moved up and down in the vertical direction and is intended for inserting dowels 36 into the road surface 12. In the area of these dowels 36, a parting line is cut as a predetermined breaking point in a subsequent operation.
  • FIG. 2 shows the basic structure of the device according to the invention for the automatic control of the pre-scraper height.
  • the distributor 22 is omitted here.
  • the scraper 32 in the form of an elongated plate with a lower horizontal longitudinal edge and a slightly inclined upper edge towards the pressure plate 26 pushes a mountain of paving material 24 in front of it.
  • the slipform paver according to the invention is suitable both for a single-layer ceiling structure (FIG. 1) and for a two-layer structure (FIG. 2). In the latter case, a second layer 12b of wear-resistant split concrete is applied to the prefabricated first layer 12a made of less expensive round-grain concrete, which is shown in FIG. 2.
  • a particularly water-rich slurry or slurry layer 57 is formed on the surface of the material 24.
  • the thickness of this slurry layer 57 is approximately constant for a given moisture level of the supplied installation material 24.
  • the horizontal underside of the pressure plate 26 is approximately at the level of the bottom of the slurry layer 57.
  • the thickness of the slurry layer on the paving material below the pressure plate 26 depends on the level c of the paving material removed from the scraper 32 in front of the pressure plate 26, this thickness can be readjusted by changing the slurry level in front of the pressure plate 26.
  • the readjustment can be based on the level h of the slurry surface, since the slurry layer 57 in front of the pressure plate 26 has an essentially constant thickness d with the concrete consistency remaining the same. It can be seen that the level can be raised by lifting the pre-stripper 32. Accordingly, the pre-stripper 32 is lowered to lower the level.
  • a cylindrical float 56 with a horizontal cylinder axis 56a, which extends transversely to the direction of movement A, is used to determine the actual level, which is immersed in the slurry layer 57 in the region above the bottles 30.
  • the floating body 56 is articulated on the inside of the preliminary scraper 32 by means of an approximately horizontally extending connecting link 58 (pivot pin 60).
  • An approximately vertical measuring rod 62 is in turn articulated on the connecting link 58, specifically at a point (reference point 64) which lies approximately halfway between the distance a from the cylinder axis 56 and the pivot pin 60.
  • the upper end of the measuring rod 62 passes through a corresponding bore of a switch actuating element 66; a locking screw 66a that is radial with respect to the measuring rod axis allows the switch actuating element 66 to be fixed in different height positions on the measuring rod 62.
  • An electromechanical three-point switch 68 is attached to the frame 16a of the slipform paver 16 in the area of the upper measuring rod end, the switch lever 68a of which extends horizontally in a central or neutral position and from this position in a vertical plane upwards to an upper end position and downwards in a lower end position is pivotable (dashed or dotted lines in FIG. 2). 2, a movable contact 68b following the lever movement is indicated, which is exposed in the central position of the lever 68a, touches the fixed contact 70a in the upper end position of the lever and the fixed contact 70b in the lower end position of the lever. Similar to the thermostat controls, the switchover from the middle position to the upper contact position and back can be provided with a switching hysteresis. The same can also be provided for the transition to the lower switching position and back.
  • the two fixed contacts 70a and 70b are connected to a control circuit 74 via corresponding electrical lines 72a and 72b, indicated by dash-dotted lines.
  • the circuit 74 controls a four / three-way valve 76 via a control line 78.
  • the two upper connections of the valve 76 are on the one hand to one Hydraulic line 80a connected, which leads to the pressure connection of a hydraulic pump 82 and the other to a return line 80b, which opens into a hydraulic oil reservoir 84.
  • the pump 82 is supplied with pressure fluid from the reservoir 84 via a line 80c.
  • the two lower connections of the valve 76 in FIG. 2 are connected to the two connections 50a and 50b of the double-acting cylinder 50 via hydraulic lines 80d and 80e.
  • a working piston 52b provided on the piston rod 52a in the interior of the cylinder divides the cylinder interior into two working spaces, the working space surrounding the piston rod 52a planarly being connected to the connection 50b and the other to the connection 50a.
  • valve 76 In the central position of valve 76 shown in FIG. 2, line 80a is connected to line 80b; the lines 80d and 80e, on the other hand, are shut off by the valve 76.
  • the piston 52b can therefore not move in the axial direction within the cylinder 50, so that accordingly the preliminary scraper 32 is immovable relative to the pressure plate 26 via the blocked piston rod 52a and the double arm lever. If for some reason the level of the paving material 24 including the slurry layer 57 rises relative to the pressure plate 26, the float 56 is raised and with it the measuring rod 62, but by half the way.
  • the switching lever 68a of the switch 68 Since the free end of the switching lever 68a of the switch 68 is articulated on the switch actuating element 66, the switching lever 68a pivots in accordance with the movement of the measuring rod. As soon as the upper end position of the lever 68a is reached, the switch 68 switches over, which results in the contacts 68b and 70a closing. A corresponding signal is fed to the control circuit 74 via the line 72a, which then controls the hydraulic device formed from the pump 82 and the valve 76 in such a way that the pre-stripper 32 is lowered. For this purpose, the valve body of valve 76 in FIG. 2 is shifted to the left into the corresponding switching position, in which line 80a is connected to line 80d and line 80b is connected to line 80e.
  • the pump 82 If the pump 82 is not running continuously, it is started by the circuit 74 via a line 74a, whereupon the corresponding hydraulic pressure causes the piston rod 52a to extend and the lowering of the preliminary scraper 32. Since the level h only changes after a relatively large time delay after When the lowering of the preliminary scraper 32 changes accordingly, the cylinder axis 56a forms a momentarily spatially constant pivot axis with respect to the connecting link 58 when the preliminary scraper 32 is lowered. As a result, the measuring rod 62 lowers by half the distance covered vertically downward by the preliminary scraper 32 until finally the switch 68 switches back to its neutral middle position. The control circuit 74 then switches the valve 76 back into the central position shown in FIG. 2, in which the preliminary scraper 32 is stationary relative to the pressure plate 26.
  • the control circuit 74 switches the valve 76 into the third switching position in which the lines 80a and 80e and the lines 80b and 80d are connected to one another.
  • the piston rod 52a is consequently pushed into the cylinder 50 and the preliminary scraper is raised accordingly until finally the switch 68 is moved into its central position via the moving switching rod 62. is switched.
  • the target level can be changed in a simple manner by loosening the locking screw 66a, displacing the switch actuating element 66 accordingly and again with the locking screw 66a on the measuring rod 62 specifies.
  • the switch actuating element 66 must be attached to the measuring rod 62 at a comparatively lower point on the latter; to lower the desired level, the switch actuating element 66 must be moved upwards.
  • the nominal height h can be reliably kept in a range of 11 ⁇ 2 cm with little mechanical effort, with a thickness of the top layer 12b of 6 to 7 cm.
  • the thickness of the lower layer 12a is approximately 15 cm.
  • the height control is based on the height h 'of the reference point 64 as the actual value. Accordingly, the sum of the sludge level setpoint and the distance b of the cylinder axis 56 forming the center of buoyancy of the floating body 56 from the sludge surface results as the desired value.
  • the height h in turn is composed of the thickness c of the actual concrete layer and the thickness d of the liquid slurry layer 57.
