Definitions

  • the present invention relates to a laying device for objects, in particular a stone laying device, having the features of claim 1.
  • Such stone laying devices are known. For example, goes from the DE 198 14 882 C1 a molded brick laying apparatus having an aligning cylinder for operating Ausrichtbacken, a gripping cylinder for actuating gripping jaws and a Abdrückzylinder for actuating a Abdschreibdazzling. All cylinders are connected to a single reversible hydraulic circuit.
  • the actuation of the individual cylinders is carried out with a valve sequential control such that in the closing operation of the laying device initiating position of a control lever initially the gripping cylinder is pressurized by the flow pressure of the hydraulic circuit in the closing direction of the jaws, that when exceeding a first threshold pressure in the flow line of the alignment in the closed position of the alignment jaws and the gripping cylinder are pressurized again in the opening direction of the gripping jaws, that when a second pressure threshold in the flow line, which is higher than the first pressure threshold is exceeded, the gripping cylinder is pressurized again in the closing direction of the jaws and that when a third Pressure threshold in the flow line, which is higher than the second pressure threshold, the Abdrückzylinder is pressurized so that the Abdrück worn nails presses on the outer row of blocks.
  • the movements for opening the gripping jaws then run off.
  • a problem of such a hydraulic valve sequencing is that the operation of the thus controlled Formsteinverlegevorraum is precisely defined and not individually variable.
  • filters are required to protect the individual pressure follower valves from contamination. This means that the whole system is prone to failure and maintenance intensive and therefore expensive.
  • Another disadvantage of the known embodiments is that two hydraulic oil connections with reversible flow and return are necessary to produce the corresponding opening and closing movements on the part of the carrier device.
  • the object of the present invention is therefore to design a laying device for objects in such a way that it can also be operated in connection with carrier devices with non-reversible hydraulic connections.
  • the essential advantage of the invention is that the present laying device can be operated both in connection with reversible and with non-reversible hydraulic connections.
  • the present laying device can be operated in particular in connection with carrier machines that have no reversible hydraulic connections, because the present invention for controlling cam control device can be operated either in both directions of rotation.
  • the present laying device is relatively less susceptible to interference and relatively low maintenance. For this reason, the operation of the present laying device is relatively inexpensive.
  • FIG. 1 shows a hydraulically actuable laying device 1 according to the invention, which is used in particular for laying the molded brick layers.
  • the laying device 1 has a central suspension device 2, which is fastened with the aid of chains or the like on the boom of a mobile excavator, not shown, or the like driving device.
  • the laying device 1 has a holding crosspiece 2 'connected to the suspension device 2, which is formed substantially rectangular.
  • the holding traverse 2 ' is connected at its lower side by means of four articulation points 102 with a holding frame 3.
  • jaws 4a, 4b On the holding frame 3 are in opposite directions in one direction jaws 4a, 4b, which are actuated by a cylinder 5, arranged.
  • alignment cylinders 6a, 6b lying opposite one another are arranged with respect to the holding frame 3, which can be actuated in the illustrated example by two separate alignment cylinders 7a, 7b.
  • the gripping jaws 4a, 4b can engage the one opposite sides of a molded block layer.
  • the alignment jaws 6a, 6b can engage the other opposite sides of the molded brick layer
  • the laying device 1 For laying a layer of molded bricks arranged in the composite, the laying device 1 is first moved over such a molded brick layer, wherein this shaped brick layer is usually the uppermost layer of a stack consisting of several stacked molded brick layers.
  • both the alignment jaws 6a, 6b and the jaws 4a, 4b are opened.
  • the jaws 4a, 4b After placing the laying device 1 on the top mold stone layer, wherein not shown in detail, connected to the support frame 3 support rails rest on the mold layer, are e.g. First, the jaws 4a, 4b briefly closed to align the stones of the molded brick layer clean.
  • the gripping jaws 4a, 4b are opened again and the alignment cylinders 6a, 6b are closed in order to move the stones in the molded brick layer.
  • the gripping jaws 4a, 4b are then closed to clamp the molded brick layer and the alignment jaws 6a, 6b are opened again.
  • a Abdschreibzylinder (not shown) can be actuated, which presses a Abdschreib driving (also not shown) against the held between the jaws 4a, 4b molded block position.
  • the Abdschreib shark is biased by provided spring elements against the mold stone layer.
  • the thus taken shape stone layer can now be moved by pivoting the laying device 1 to a place of installation in a pavement to be created pavement and moved and sold in the correct position next to the already laid pavement.
  • the molded brick layer is pressed by the biased Abdschreib worn on the sand or gravel bed of the pavement.
  • the laying device 1 described so far is known.
  • the present invention provides a cam control device instead of the known automatic hydraulic control via pressure sequence valves, which controls the valve stem of the individual control valves, the gripping cylinder 5 for actuating the gripping jaws 4a , 4b, the alignment cylinders 7a, 7b to actuate the Ausrichtbacken 6a, 6b and the cylinder of the Abdrückvorraum drive.
  • this cam control device consists of a driven by a motor, preferably a hydraulic motor 10 drum member 11, the spaced apart on its peripheral surface in the longitudinal extension of the drum member 11 spaced apart cam rings 12, 13 and 14, which are fixed against rotation on the surface of the drum member 11 ,
  • the hydraulic motor 10 is mounted in a frame part 16 of the laying device 1, such that its output 17 is rotatably connected or connectable to the drum part 11 rotatably mounted in the frame part 16.
  • valve block 18 which has substantially juxtaposed control valves 19, 20 and 21, which can be actuated in the manner shown on valve tappets 23, 24 and 25 respectively.
  • valve block 18 two ports for applying the pressurized fluid to a control valve in reversible form are each provided.
  • a valve stem is actuated by a cam ring, when the drum part 11 rotates.
  • the cam ring 12 controls the valve tappet 23 of the control valve 19, the cam ring 13, the valve stem 24 of the control valve 20 and the cam ring 14, the valve stem 25 of the control valve 21st
  • the cam rings 12, 13, 14 each have areas of different thickness, which are offset from each other in the circumferential direction, so that in each case a predetermined time sequence control of the control valves 19, 20 and 21 results.
  • one cycle of the sequential control corresponds to one revolution of the roller or drum part 11.
  • the drum part 11 can be exchanged for another drum part in a simple manner, according to the other desired Has valve sequence control on its circumference designed cam rings.
  • it can be advantageously provided to divide the cam rings into individual segments, for example, into three segments each extending over 120 ° in order to allow a changed valve sequence control to proceed particularly simply and quickly.
  • the individual segments are screwed, for example, on the circumference of the drum part 11.
  • FIG. 1 A block diagram of a hydraulic system for controlling the laying device shown in Figure 1 with the cam control device such that, for example, when gripping a top mold stone layer of a stack of molded brick layers respectively the gripping jaws 4a, 4b are short to align the stones, then the gripping jaws 4a, 4b are opened, then the alignment jaws 6a, 6b are closed to move the stones, then the gripping jaws 4a, 4b are closed for clamping the stones in the laying device 1 and the jaws 6a, 6b opened again, the Figure 3.
  • the hydraulic fluid is applied via the main ports 35, 36 and selectively applied to the hydraulic motor 10 via quantity valves 37, 38 depending on the desired direction of rotation.
  • the applied via the main ports 35, 36, the main amount of the pressurized fluid passes through the control valves 19, 20, 21 controlled to the gripping jaws 4a, 4b associated gripping cylinder 5, to the alignment jaws 6a, 6b associated alignment cylinders 7a, 7b and associated with the Abdschreibvorraumplatzzylinder 9.
  • the cam control device can also be designed differently, as long as it fulfills the same functions for valve following control.
  • the cams can also be moved linearly to actuate the control valves.
  • a rod or the like by a drive in Axialraum moves, wherein the cams in the longitudinal direction of the rod spaced from each other are arranged on the rod.
  • the stroke of the rod preferably corresponds to one cycle of the sequential control.
  • the present cam control device can also be extended by a plurality of cam rings and control valves, so that additional actuators can be actuated in the case of special laying formations.
