Definitions

  • the invention relates to a conveying device for conveying piles with a continuous conveying means, in particular designed as a belt or chain conveyor, with a machine frame and a shovel pivotably linked to boom arms, the boom arms being attached to a rocker arm pivotally hinged at the front end of the machine frame Are pivotally articulated in height and the cantilever arms and the rocker are connected to the front end of the machine frame by means of cylinder-piston assemblies, and a feed chute is arranged above the continuous conveyor in the area of the front end of the machine frame facing the pile, with the loading shovel for throwing off the pile.
  • Work in the feed chute can be pivoted about at least one substantially horizontal axis crossing or intersecting the longitudinal axis of the discharge device and the pivot drive of the extension arms covers a pivot angle at which the upper edge the rear wall of the loading shovel arrives above the feed opening of the feed chute and forms the run-off edge of the material to be conveyed received by the loading shovel.
  • Swing arm and the cantilever arms as well as additional pivoting of the loading shovel cause a transfer of the picked up material to a continuous conveyor, taking into account the transfer of the picked up for such an overhead
  • Machine center of gravity had to be raised and pivoted, so that a correct weight distribution in the longitudinal direction of the conveyor had to be taken care of to prevent tipping.
  • the required stability in such a device can only be guaranteed by appropriate weight and correspondingly long training of the continuous conveyor as a counterweight arm.
  • the invention now aims to develop a device of the type mentioned in such a way that the load pick-up is improved while reducing the risk of tipping and at the same time creating conditions which offer better maneuverability and maneuverability of the device without an increased risk of tipping.
  • the device according to the invention is that. the support of the or the cylinder-piston unit (s) for the rocker at the front end of the machine frame, seen in side view, is arranged behind the support of the rocker at the front end of the machine frame.
  • the kinematics of the linkage of the rocker and the rocker drive selected here enables a more compact overall construction and is taken into account accordingly, taking into account the fact that the entire pivoting path is covered closer to the front edge of the machine frame and thus closer to the tilting edge defined by the front wheels use shorter continuous conveyors and thus reduce the overall length of the machine, which already makes the maneuverability clear is increased.
  • the support of the cylinder-piston unit for the rocker in the specified manner also offers better load absorption, since such a cylinder-piston unit is pressurized on the piston side for retracting the blade into the pile and for subsequently lifting the blade , while comparable constructions, such as, for example, the above-mentioned construction according to AT-PS 380 451, have accepted a tensile load on the swivel drive here.
  • the design according to the invention is developed so that the support of the rocker at the front end of the machine frame lies in the side view between the machine frame-side supports of the cylinder-piston units for the pivot drive of the rocker and the cantilever arms.
  • cylinder-piston units which are dimensioned according to the forces to be absorbed can be accommodated in a space-saving manner without any restrictions or obstructions being caused by the relatively large pivoting path of the extension arms and the bucket.
  • a particularly compact design is obtained when the design is made such that the cantilever arms are cranked and that the free ends of the cantilever arms, to which the bucket is pivotally articulated, essentially stand when the bucket is lowered near the front end of the machine frame ⁇ Lichen parallel to the cylinder-piston unit (s) for the height pivoting of the boom arms.
  • the maneuverability and Improve maneuverability by the fact that the machine frame consists of a frame front part and a frame rear part, which are connected to each other via an articulated joint with a joint axis extending transversely to the machine direction, and that the continuous conveying means is formed by two adjoining conveyors whose transfer point is in the area the articulation of the frame parts.
  • Such articulated joint in the machine frame has the consequence that in angled position, the center of gravity Läge is shifted significantly, with significantly without simultaneous improvement of kinematics to reduce the danger of tipping over in a derar ⁇ term pivoting a machine frame rear part with respect to the machine frame front part of the risk of overturning would take zu ⁇ '. Due to the fact that the movement path of the loading shovel can be moved closer to the front edge of the front part of the machine frame and thus closer to the tipping edge of the front wheels, it is now also possible to design the front shovel loaders, for example from DE-OS 3 200 084, as articulated links can now be used in a compact device which at the same time carries a movable continuous conveyor which can be adapted to the requirements.
  • a particularly compact and short construction for the swivel drive of the loading shovel relative to the extension arms or to a cross member, which in turn can be swiveled relative to the extension arms, can be achieved in that the drive cylinder piston units for the swiveling of a cross member for the loading shovel and the swiveling of the loading shovel are arranged crossing each other relative to this cross member.

  • Fig. 2 is a plan view in the direction of arrow II of the discharge device of Fig. 1
  • Fig. 3 in an enlarged scale a side view of the articulation of the loading shovel over the boom arms and swing arm.
  • the discharge device 1 shown in FIGS. 1 and 2 has a frame front part 2 and a frame rear part 3, which are pivotally connected to one another via a schematically indicated articulated joint with an articulated axis 4.
  • the frame parts 2 and 3 can be moved via wheels 5.
  • a front frame part is, as is shown in more detail in FIG. 3, a loading shovel 8 articulated via a rocker arm 6 and extension arms 7, with a dashed line in FIG. 1 showing some positions of the loading shovel 8 and associated pivoting paths of the front edge 9 of the loading shovel 8 are indicated.
  • Material or pile picked up by the loading shovel 8 is transferred to a first continuous conveyor 10, for example a belt or chain conveyor, via a feed chute 35 in the area of the front end of the front frame part 2 and subsequently via a transfer point 11 located in the area of the articulation axis 4 transferred to a second continuous conveyor 13, which is mounted on the rear frame part 3 and can be raised and lowered via a cylinder-piston unit 12.
  • the second conveyor 13 can be raised and lowered in the sense of the double arrow 14 by the cylinder-piston unit 12 and articulated at 15 on the rear frame part.
  • the articulation of the first conveying means 10 on the frame front part 2 is indicated by 16.
  • the conveyors 10 and 13 are mounted on damping blocks 17, so that, together with the articulated arrangement of the conveyors 10 and 13, the impact forces occurring during the transfer of the material can be at least partially damped.
  • the frame rear part 3 can be pivoted relative to the frame front part 2 by a relatively large angle c, which can be, for example, in the order of 30 ° from the central axis, so that when pivoting in this way into one of the two screed - If indicated side positions result overall there is a visible shift of the center of gravity of the entire discharge device towards the front end of the machine or towards the loading shovel and its articulation.

  • the kinematics for the loading shovel which is shown in more detail in FIG. 3, is selected, in FIG. 3 that at the front end of the machine frame next lying position is shown.
  • the rocker arm 6 is articulated on the machine frame front part 2 via a articulation point 18 and via a cylinder-piston unit 20 articulated on the frame at 19, which engages the rocker arm 6 at 21 at the end opposite the articulation point 18, in the direction of a movement of the loading shovel 8 pivotable to the pile.
  • cantilever arms 7 are pivotably articulated, which can be actuated via at least one cylinder-piston unit 24 articulated on the machine frame at 23, the cylinder-piston unit 24 acting at 25 in the region of the offset of the cantilever arms 7.
  • a crossmember or support 27 for the loading shovel 8 is articulated to the boom arms 7 at 26, which can be pivoted via at least one cylinder piston unit 28 via an articulated linkage 29 on the boom arms and an articulated linkage 30 on the crossmember or support.
  • At least one further cylinder-piston unit 31 is provided, which engages the cross member 27 in the region of the • pivot axis 26 of the cross member 27 and the articulation point thereof the loading shovel 8 is designated 32, the pivot axis of the loading shovel being designated 34.
  • the arrangement of the cylinder-piston assembly 20 in a side view behind the rocker 6 also makes it possible for insertion the piston force becomes effective in the pile or material to be picked up on the cylinder-piston unit 20.
  • the parallel arrangement of at least the cylinders 20 and 24 of the rocker 6 in the fully retracted state is favored by the cranked configuration of the extension arms 7, so that the loading shovel 8 as a whole comes to lie very close to the front wheels.
  • a further improvement in the compact design also results from the fact that the cross member or support 27 is articulated to the jib arms near the lowest point at 26 at 26, the kinematics of the loading shovel due to the crossed arrangement of the cylinder-piston assemblies 28 and 31 8 is further improved, particularly when lifting and ejecting.

  • the removal device 1 can in any case load parallel to the base and it is ensured that the operation of the loading shovel for material transfer will be carried out without risk of tipping over.
  • the risk of tipping must not least be eliminated because the discharge device is used at relatively low track heights and the. There is no free space to the roof for the machine to tip over and a correspondingly long, appropriately designed conveying means serving as counterweight cannot be used.
  • the base-parallel movement of the blade in the direction of the heap for the reception of the material can be further improved, with the chosen arrangement of the cylinder-piston units 20 and 24 relative to the articulation of the rocker 6 so that the method in In the direction of the pile, the cylinder-piston units 20 and 24 are actively communicated.
