Definitions

  • the present invention relates to a device for adjusting a height of a side plate of a paver relative to a screed of the paver, the side shield by at least two separately height-adjustable lifting devices, which are attached to a main frame of the paver, which is connectable to the screed attached, lifted and can be lowered in order to prevent a built-in material from escaping sideways, before the building material is compacted by the screed to a road surface.
  • the present invention relates to a method for manufacturing a pavement with a paver, the a screed with a maximum paving width and which is provided with a device according to the invention, wherein the road surface to be produced has a width which is greater than the maximum installation width.
  • Paver is understood below to mean a class of construction machines, such as e.g. Pavers with which so-called paving material of various qualities (such as asphalt, concrete or the like) can be laid on a subsoil intended for this purpose, such as, for example, asphalt.
  • a planum as far as possible in high compression quality just and profile-appropriate laid. Planum refers to a base course on which a road, a path, a building or similar can be built.
  • Telescope collars are known with which varying road widths can be made.
  • a screed then consists of several elements, of which at least one transverse to the installation direction, ie parallel to the width of the road, can be moved variably. In this way, different road widths can be made.
  • this technique also reaches its limit, namely, when the telescopic screed is maximally extended.
  • This object is achieved with a device for adjusting a height of a side plate of a paver according to the type mentioned above, wherein the two lifting devices are connected to one another with a connecting element and a central adjusting device is provided which cooperates with the connecting element such that the two separately height-adjustable Lifting devices are simultaneously height adjustable by actuation of the adjustment.
  • the side plate of a paver can be easily lifted and lowered in a simple manner.
  • the actuation of the two lifting devices is effected by a central movement of the adjusting mechanism according to the present invention.
  • Manual operation of the lifting devices as is common in the art, has only a secondary meaning. The sometimes very time and effort consuming Verstellarbeit deleted completely.
  • the two lifting devices can be quickly raised and lowered together, so that a road widening beyond the permissible installation width can be done easily and quickly.
  • Another advantage of the present invention is that the device according to the invention can be easily and quickly mounted on existing side plates or their lifting devices, so that a conversion of a side plate according to the prior art towards a side plate according to the present invention easily, quickly and cost is possible.
  • the central adjusting device is driven mechanically, electrically or hydraulically.
  • the lifting devices are realized as headstocks, which are each connected via a chain to the side plate, and when the connecting element is a traverse, which is connected to the central adjusting device.
  • the two separately height-adjustable lifting devices are arranged symmetrically to the side plate, and the central adjusting device is arranged centrally between the two lifting devices and connected to the main frame.
  • This arrangement geometry prevents the force exerted on the two lifting devices by the adjusting device according to the invention being distributed unevenly. Due to the symmetrical arrangement experienced both lifting devices an equally large force component, so that tilting of the side plate can be excluded.
  • the central adjusting device comprises an adapter plate, a drive unit and an adjustment mechanism, wherein the adapter plate and the adjustment mechanism are coordinated such that the adjustment gradually can cause a change in height by the adjustment on the adapter plate and climbs up, the adjustment mechanism in the Snap adapter plate when a desired height is reached.
  • the engagement of the adjustment mechanism in the adapter plate ensures that the desired height adjustment does not change during a work process.
  • An adjustment mechanism, which can climb up or down on the adapter plate, can be produced in a simple manner. This results in a cost-effective production, so that, for example, a retrofitting of existing road paver can be done cheaply.
  • Another advantage is the fact that in addition a fold-off stripping device is provided, which is mounted laterally of the screed with a hinge on the main frame to, when the side plate is in a raised state, the built-in, then laterally next to the screed is led to strip.
  • the operation is further simplified by the worker does not have to distribute the laterally conveyed next to the screed built-in to reduce it to a desired covering thickness. Similar to the screed, the scraper simply travels over the additional screed in addition to the screed and pulls this additional slick "smooth". This measure in turn increases the speed with which an additional road width can be made.
  • the stripping device comprises a detent element with which the stripping device can be fixed relative to the main frame at a desired angle relative to an installation direction.
  • the stripping device is height adjustable relative to the main frame.
  • a covering thickness can be made laterally next to the screed of the paver, which differs from the lining thickness, which is made by the screed.
  • a thicker side coating could be made by the distance between scraper and planum is chosen to be greater than the distance between screed and Planum.
  • a height dimension can be set, which end-compressed state of the covering can be achieved profile accurate.
  • the stripping device comprises an extension plate, with which a stripping length is variably adjustable.
  • an extension plate can be used to increase the maximum installation width required.
  • the stripping device comprises a heating element.
  • the heating element ensures that the built-in material, which is usually poured hot in front of the screed, does not stick to the scraper and affects the surface of the covering.
  • the inventive method comprises the following steps: adjusting the side plate in the raised state by operating the central adjusting device; Unfolding and locking the stripping device; Conveying the material to be installed via a distributing device upstream of the screed, in particular a screw, beyond the width of the screed; and stripping of beyond the screed also funded built-in.
  • Fig. 1 shows a schematic side view of a road paver 10, which has a height-adjustable side plate according to the present invention.
  • the road paver 10 is movable in a driving and installation direction 14 using caterpillars 12, which can also be replaced by wheels.
