Definitions

  • the invention relates to a device for laying paving stones with a movable chassis, a cantilever arm that is height-adjustable relative to the chassis and a gripping tongs element that is attached to the cantilever arm so that it can be rotated and pivoted in a pendulum manner and to move.
  • Such a device is known from DE-GbmS 72 31 217, in particular there of FIG. 5, which is used to lay larger block-shaped or plate-shaped road surface elements, the gripping pliers with their clamping jaws being many times the load of such a road surface element can attack from the side, which is also necessary for reliable holding.
  • the pliers used there have an opening angle of approximately 180 ° spread jaws, the suspension acting directly in the area of the jaw linkage.
  • Such a simple pliers construction can grasp one-piece blocks, if necessary also a row of paving stones, but it is not able to reliably detect blocks or stone rows lying side by side, in which length differences cannot be compensated for.
  • the object of the invention is to provide a device which, when paving, enables the laying of paving stones in groups, in particular in more than two adjacent rows, in a simple, reliable and exact manner.
  • the gripping pliers element has a set of more than two gripping pliers, which are mounted in a common plane of engagement, are arranged and act in parallel, and in which pivotally mounted clamping jaws have levers such as levers the suspension are connected so that they move in the direction of the clamping engagement under load and each of the tongs is individually connected to the suspension of the gripping tongs element by load-distributing lever transmissions in the form of a system of balance beam.
  • the gripping pliers element with more than two gripping pliers mounted in a common plane of attack and with pivoting clamping jaws ensures that the clamping jaws do not lower differently depending on the required clamping path. Rather, the common level of engagement ensures that the stones or rows of stones lying next to one another also remain in a common plane. Nonetheless, the gripping tongs are simultaneously equipped with clamping force by the load-distributing lever transmissions, so that shorter stones or rows of stones cannot fall down due to lower clamping forces due to tolerances.
  • the device consists of a chassis 1 with a wheel axle 2, a support axle 3, a hydraulically moved cantilever arm 4 and a gripping tongs element 5 hanging thereon.
  • the gripping tongs element 5 comprises a plurality of gripping tongs 6.
  • the gripping tongs element including the concrete paving stones covered with them, is suspended via support levers 8, balance beam 9 and brackets 10 so that the weight is evenly distributed among the individual gripping tongs. This ensures that in the case of dimensional tolerances of the concrete paving stones with each other or despite contamination, e.g. Sand, every single gripper 6 clamps evenly and securely between the concrete paving stones.
  • the gripping tongs 6 are constructed so that they do not reach under the concrete paving stones, but instead press the rows of concrete paving stones by lateral pressure so that the bridges formed, formed from the rows of concrete paving stones 11, cannot break through. The same effect can be achieved if the concrete paving stones are gripped and clamped across the line.
  • a force P 2 necessary for this on a gripping pliers 6 is generated by lever transmission from a force P l which corresponds to the weight of the concrete paving stones and associated parts of the gripping pliers element 5 gripped by the gripping pliers 6.
  • the support levers 8 for each gripper 6 are mounted on the associated clamping jaws 7 (cf. FIGS. 3 and 4). They transmit the translated greater force via pull tabs 12 to angle lever clamping jaws 13.
  • the angle lever clamping jaws 13 exert the force P 2 , which is a multiple of the force P, through the overall transmission, sufficient to close the bridge formed from the individual concrete paving stones 11 hold.
  • the counterforce to the force P 2 is intercepted by jaws 14 which are rigidly attached to the jaw base frames 7 so that they are always at right angles to the concrete paving stones 11.
  • a cable 15 can be guided from the clamping jaw base frames 7 to the operating side of the device, which is pulled and locked via a lever transmission 16, so that all levers of the gripping tongs element 5 are relieved and the movable angle levers 13 that open up by their own weight are opened are.
  • the gripper element then hangs on the clamping jaw base frames 7 and not, as when clamping, on the balance beam 9.
  • a linkage with a corresponding redirection of the power transmission can also be selected.
  • the change in the suspension can be done in different ways, e.g. with hook and eye.
  • the clamping jaws 14, which are rigid with respect to the interconnected base frames 7, are located in the joints between the already laid and the newly added concrete paving stones. So that they do not jam in the joint when lifting and cause displacements of the concrete block paving, they must be pulled up vertically.
  • a push-off lever 17 is mounted on the base frames 7 approximately in the middle between the rigid clamping jaws 14 and the center of gravity of the empty gripping tongs element 5.
  • the suspension on the cable 15 is attached to one end of the lever 17 above the center of gravity of the empty gripper element, while the other end of the lever 17 can rest on the paving stones 11 near the jaws 14.
  • the concrete block layer must be able to be connected exactly to the lying pavement. Therefore, the gripper element 5 must be rotatable and pivotable in all directions. In addition, the floating concrete paving stone layer must always hang horizontally, regardless of the position of the device. Therefore, the suspension on the cantilever 4 with the fixed webs 18 is pivotally connected to an eye tab 19 via a bolt 20. For the possibility of swiveling in the direction offset by 90 ° provides a bearing pin 21. An angled horizontal disc 22 rests in a corresponding pan 23 for the possibility of rotation about a vertical central axis. The disc 22 is firmly connected to the eye pin 24.
  • the cantilever arm 4 In order to raise the gripper element 5 to such an extent that a layer of concrete paving stones can be removed from a package up to a height of approximately 1.20 m, the cantilever arm 4 is raised by a hydraulic cylinder 25. Here, the cantilever arm 4 swivels around a bearing 26.
  • a pressure vessel is attached to the device, which is partly filled with oil and partly with compressed air.
  • the chassis 1 is formed from tubes and also serves as a pressure vessel. From the lower area, in which the oil under pressure is located, a line goes to the hydraulic cylinder 25 via a manual valve.
  • a manual valve is opened.
  • the pressurized oil extends the hydraulic cylinder.
  • the height of the gripper pliers element 5 brought to the level of the concrete block paving is determined by closing the manual valve, since there is only oil in the hydraulic cylinder 25 and in the lines.
  • the cantilever arm 4 can also be lifted from prestressed springs by means of spring force without compressed air storage, the hydraulic cylinder 25 also being extended. Then the hydraulic cylinder 25 is used only for lowering and locking. The oil container is then not under pressure. The lowering is done as previously described, whereby the springs are tightened again.
  • the cantilever arm 4 is lifted by spring force and a mechanical brake is used instead of the hydraulic cylinder described above.
  • the concrete block paving layer is lifted by tilting the entire device around the wheel axis 2 as with a hand truck.
  • the laying of the concrete paving stones is done in the same way.
  • handles 27 are expediently arranged one above the other.
  • some concrete paving stones can be placed in a basket 28 as a counterweight.
  • the pressure in the hand is reduced and handling is made easier.
  • a container for sand or the like can also be attached.
  • the wheels of the wheel axle 2 are braked separately.
  • the braked or locked wheel then serves as a fixed fulcrum to allow the other wheel to roll over an obstacle by turning the entire device sideways.
  • Operating levers for the brakes are arranged on the handles 27 so that the handles do not have to be released when braking.
  • the transmission to the brakes of the wheels can be carried out using a linkage, cable or Bowden cable.
  • an additional device for rearranging the concrete paving stones within the concrete paving stone layer is required.
  • the weight of the concrete paving stones is used as an initial force.
  • FIGS. 5 and 6 An additional device provided for this purpose, shown in FIGS. 5 and 6, consists of a support table 29 with four legs 29 '.
  • the legs 29 ' are designed as hydraulic cylinders which are held in the extended state by springs 30 when the support table 29 is reloaded.
  • the springs 30 are compressed and the hydraulic cylinders are retracted.
  • the oil displaced in this way is pressed through interconnected lines 32 into horizontally acting parallel working cylinders 33 on the support table 29.
  • Piston rods 34 of the working cylinders 33 extend and push the concrete paving stone rows in front of opposite stops 35.
  • the springs 30 provide for the lifting of the support table 28 as well as for the extension of the hydraulic cylinders of the legs 29 ′ and the insertion of the piston rods 34 .
  • the support table 29 can also be provided with rigid legs which are attached on one side. A counterweight ensures that it is horizontal when not in use. When the concrete paving stone layer is placed on it, the support table 29 tilts and is thus tilted so large that the concrete paving stone layer slides on it until every row of concrete paving slips before a stop. In order to reduce the friction of the concrete paving stones, the support table 29 can be designed as a roller table.
  • the support table 29 tilts back into the horizontal starting position.
