Definitions

  • the invention relates to a self-propelled device with a chassis and a suction lifter fastened to at least one adjustable boom with a rectangular outline for lifting and moving transportable heavy concrete parts, in particular for laying concrete paving stones (CH-A-445546 or FR-A-1461504) .
  • This work also occurs before the stone layer is picked up from the delivered pallet stack, so that a lot of time is wasted with each laying operation.
  • the components can only be transported and displaced working from this laying device when viewed in the direction of travel.
  • it is only possible to move a layer width so that once a layer has been set, the vehicle has to move a new one individually to the laying point.
  • the driving work to be performed in this way is considerable.
  • the area of application is limited to areas whose sizes correspond at least to the range of motion of the chassis.
  • the use of the device is thus when laying stones on narrower surfaces, such as footpath and bicycle path u. Like., not possible. Also can not from below, d. H. if the vehicle were to stand on the road surface, work would be carried out because the short extension of the cantilever arm would not allow several layers of stone to be moved against the curb. As the laying work progresses in the case of larger areas, the route to be covered by the device becomes ever greater due to the increase in the distance between the storage location of the components outside the area and the place of installation.
  • the known device is equipped with a gripper with which the components, for example paving stones, are grasped and held by a clamping action when lifting.
  • the components are thus pressed against each other and thus prevented from slipping down.
  • the stone layer would fall out of the jaw.
  • half of the stones in order to be able to lay a bandage requested by the purchaser of a paving, such as "herringbone pattern", half of the stones must be missing from the individual stone layers, which are closed by inserting whole individual stones after placing a second stone layer with exactly opposite empty spaces of half stone sizes . This ensures the continuation of the original association.
  • this gripper cannot be used with plate-like laying elements, because they would dodge upwards or downwards due to their flat shape and small edge area if the clamping effect occurs.
  • Claw-like elements are used to generate the clamping force, which are a hindrance when a laying unit is set down. For example, they prevent the parts to be laid against each other. Therefore, these cannot be lowered to the sand level in order to then release the claws, but to prevent the claw-like gripping elements from reaching between the parts that have already been laid and the parts to be laid, the latter must slide out of the gripper shortly above the ground, so that they cover the last part of the way in free fall.
  • the disadvantage here is that the components to be installed do not come to rest exactly flush, which is particularly disadvantageous in the case of smaller units, such as paving stones.
  • the joint pattern shifted as a result must be corrected immediately by a second helper for each stone layer so that it does not work out of the right-angled grid at all when laying it on again.
  • considerable frictional forces occur between the gripping elements and the components. T. on the individual sides are of different heights and therefore irregularities when setting the unit down to lead.
  • connecting means After the stones have been laid, the connecting means should gradually disappear, for example dissolve.
  • the use of connecting means means a considerable additional work and material expenditure.
  • Concrete paving stones have a high specific weight, which makes it necessary to provide a high vacuum. Moving an entire layer of stones in one work step requires precise alignment and the full abutment of all stones.
  • the individual suction stamps of a suction lifter must be rotatable in all directions, i. H. not only about a vertical axis, but also about a horizontal one, because often individual stones are canted due to the rough packaging and delivery. In addition, the individual stones in a stone layer are not always flush in one plane, so that height compensation of the individual suction stamps must also be possible.
  • the suction lifter must have twice as many suction stamps as the stones to be lifted so that bandages (e.g. herringbone) can also be laid.
  • suction stamps are each assigned to a stone of rectangular, commercially available format (approx. 11/22 cm), regardless of whether the stone is longitudinal or transverse. For this reason, namely to be able to lay different dressings with one and the same suction lifter, this grid arrangement of two suction punches per stone was chosen.
  • the suction stamps must therefore be round and may therefore only have a certain size, given the stone formats available on the market. This results in a fixed suction support surface per suction pad with a diameter of approx. 40 mm. A possibly wavy joint pattern is also taken into account.
  • the fluctuating vacuum should be as small as possible due to a small pump in order to contribute to a low overall weight of the mobile device. This in turn presupposes that the suction cross sections should be closed automatically when a suction pad does not come to rest on the surface of a stone, but rather reaches into the void, so to speak. This is the case when laying the herringbone bandage in accordance with the regulations. With other associations, such as B. the block bandage, there are no designated spaces, so that all vacuum cleaners have to do their job. In addition, care must be taken to ensure that the vacuum position can be kept ready for operation regardless of the position of the accelerator pedal of the drive device, so that a uniform vacuum strength is present at all times.
  • a plunger is extended downward as an extension of a valve body beyond the boundary plane of the suction bell, so that when the bell is placed on the object to be lifted, the valve can be opened and the vacuum can be passed into the suction bell.
  • Disadvantages here are the reduction in the load-bearing suction area due to the tappet cross-section and the possibility of premature opening by tilted lifting material. As a result, the suction flow can be released prematurely, so that the vacuum in the suction system can break down. Leaks due to concrete sand sticking to the valve seat must also be expected.
  • a suction cup for lifting loads can be found in German utility model 69 31 165, in which the suction cross-section is initially released at the beginning of a lifting process and is also kept open, provided the suction cup is placed on the load to be lifted.
  • a sealing collar can also ensure a low level compensation due to its flexibility.
  • this has the disadvantage that the seal carries out an erasing movement with considerable wear on rough stone material. This results in a loss of the seal, which leads to failure when lifting loads with a high specific weight.
  • a large pendulum vacuum must be available for such a construction, since only then can the fluid dynamic effect, which leads to the closing of the valve body, be provided. Every time the valve is closed, considerable amounts of secondary air have to be sucked in, which stress the vacuum.
  • the large suction cross-sectional area required for lifting is reduced inadmissibly when the entire suction lifter is under greater pressure.
  • the suction lifter must first be placed on the material to be lifted and then the vacuum switched on. This means an additional operation for the operator of a self-propelled device which is already heavily loaded. Similar explanations also apply to the German utility model 7 228 550. All of the above-mentioned embodiments have the common disadvantage that subsequent adjustment of the suction bell, ie. H. after placing on the load, is not possible. But this is exactly the prerequisite for the detection of loosely lying small components.
  • the invention has for its object to provide a device of the type mentioned in such a way that when lifting a large number of individual concrete parts, in particular composite paving stones, which lie loosely together in a bond, the aforementioned difficulties are overcome and overall the device with the necessary low total weight in the It is able to run over freshly laid concrete paving stones without the formation of ruts in the not yet vibrated compound. This is intended to increase the possible use and the laying quality.
  • the solution according to the invention is characterized in that the suction lifter independently of one another has axially and angularly movable suction stamps and directional jaws which can be pivoted against the lifting material on all sides, the suction flow of each individual suction stamp being released by suitable means when it comes into contact with the lifting material.
  • the device according to the invention fulfills each and every one of the conditions mentioned above for laying concrete paving stones in particular.
  • laying paving elements ten stone layers can be moved or laid without having to move the device. This corresponds to the quantity of a standard pallet delivered by the concrete works with a stone stack.
  • the paving stones or slabs to be laid can be lowered down to the sand bed so that they cannot slide sideways. This is particularly possible when laying a first layer, which requires very precise alignment.
  • the laying elements no longer need to cover the last part of their lowering path in free fall. It is possible to lay any number of concrete pavement formats, which, without exception, are about 11/22 cm in size and approx. 85% of the total pavement requirement in the trade, with a single laying device.
  • the device according to the invention also permits laying work both on the front facing in the direction of travel and on the side thereof, without having to move the vehicle.
  • a stack of components to be laid behind the vehicle can be detected by rotating the support frame by 180 °. This makes it possible to lay very narrow strips. Narrow stripes running laterally to the chassis can thus be detected, as can be done, for example, from the roadway for laying pedestrian strips or roadway boundary edges and cycle paths.
  • additional weights can be used to do this to create the necessary counter-moment for the maximum display. These additional weights can be removed to make the weight easier as soon as it is necessary to use the device on a new paved surface.
  • the suction lifter 13 with its suction plungers 24 is placed on the stones with the straightening jaws 26 swung out or aligned in parallel
  • this alignment has two decisive advantages.
  • the laying elements are moved back into their old position by an unavoidable slight movement during transport from the concrete plant to the construction site, so that they lie in the grid on the suction pads as planned. Before they are lifted by the action of a vacuum, they are aligned exactly at right angles parallel to each other, which guarantees a constant rectangular joint pattern until the laying process is completed on the sand planum. No further work with correction of the joint pattern is required.
  • the original external pressure PO is accordingly reduced to the negative pressure P 1.
  • the negative pressure in the support tube 39, in the adjoining central bore 45 of the joint ball and in the air channels 33 of the support body can be released by a ventilation device (not shown). The siphon can then be lifted in the desired vertical direction.
  • the lower part 32 b of the support body with the air channels 33 is injection molded from plastic.
  • the execution of the suction bell 34 - also made of plastic - leads to the fact that the frictional resistance between these parts is significantly reduced in the sense of self-lubrication.
  • the slider-like effect of the suction bell 34 inside the lower part 32 b prevents the seizing of loose, unavoidable grains of sand and concrete particles, which easily lead to malfunctions in the conventional valve arrangements.
  • a vacuum is created within the suction spaces 37 in the support bodies 32 of the suction plungers 24. As a result, the stones are immovably connected to the suction pads. The entire stone layer can then be raised and swiveled to the installation site.
  • the straightening jaws 26 are pivoted out of the position shown in FIG. 3 into the starting position (FIG. 4).
  • This pivoting out of the straightening jaws 26 brings a further decisive advantage.
  • the operator's view of the stone layer hanging on the suction plungers 24 is completely released.
  • the stone layer can then be carefully aligned and brought into the correct assignment by means of the pivot pin 21 of the gripper, which can be rotated about the vertical axis, placed on the desired surface, specifically directly on the sand bed.
  • the suction plungers 24 can be pushed slightly upwards relative to their support plate 29, the return spring 38, which also serves as a damping spring, being compressed.
  • the individual suction plungers 24 are able to compensate for unevenness when setting down and relieving pressure.
  • Figures 1 and 2 clearly show the lifting of the frame and the extension arms 6 and the pivoting without moving the chassis from the spot. It can be seen in Figure 3 how the individual stone layers can be placed next to each other by pivoting in connection with lifting and lowering the frame, the outrigger arms and by actuating the pivot pin. This is made possible by the suspension of the suction lifter in a gimbal-like shape in connection with the mobility of the entire suction lifter about a vertical axis in connection with the lifting and lowering of the frame and the extension arms.
  • the cantilever arms in connection with the suction lifter 13 are pivotally attached to the frame 5 about the pivot point 7, a lever plate 8 being used in connection with a hydraulic cylinder for lifting and lowering.
