Definitions

  • the invention relates to a machine for earthworks, such as cable excavators, hydraulic excavators, backhoe excavators, loading shovel excavators or the like.
  • DE-A 32 32 163 relates to a hydraulically driven excavator which has mechanical-hydraulic working elements, such as compression springs, leaf springs, tension springs or counterweights, by means of which the dead weight of the cantilever arm and equipment (bucket, gripper, chisel and others) is lifted based on force.
  • An extension can be attached to the boom suspension, to which a counterweight (counterweight) is attached, the weight of which depends on the size of the boom arm with equipment.
  • Equipment and counterweight are mounted on a common trestle on the superstructure, a hydraulic ram being provided between the superstructure and the equipment, which may interact with a spring.
  • the disadvantage here is that due to the geometric arrangement and the pivoting of the counterweight above the superstructure, the stability of the device with the counterweight raised is absolutely in question.
  • DE-B 19 17 434 relates to a machine for earthworks, for example excavators or the like, with a rotating device arranged on a chassis, which carries a rotating tower containing the implement and a counterweight.
  • a rotating device arranged on a chassis, which carries a rotating tower containing the implement and a counterweight.
  • a vertically aligned, adjustable parallelogram support which consists of two parallel arms articulated at one end to a platform located on the rotating device and at the other at the rotating tower.
  • a piston-cylinder device is arranged between one of the arms and the platform or the turret .
  • the parallelogram and thus the shifting of the counterweight or components of the superstructure are adapted to the respective work situation or the transport purpose, which ultimately results in a relatively large construction effort since there is no operative connection between equipment and counterweight.
  • CA-A 1 008 407 relates to a machine for earthworks, in particular a hydraulic excavator.
  • the excavator contains an undercarriage that can be moved on caterpillars, on which an upper carriage is rotatably mounted via a connecting element.
  • Work equipment consisting of a boom system and a shovel is pivotally attached to the superstructure.
  • a displaceable counterweight is arranged on the end of the superstructure facing away from the boom system and is connected to the boom system via lifting elements. The shifting of the counterweight serves the purpose of ensuring the stability of the excavator in the case of excessively long boom systems, the counterweight being shifted diametrically when the boom system is extended.
  • the aim of the subject matter of the invention is to develop a machine for earthworks in such a way that the potential energy of the respective work cycle is stored with simple constructive means in order to be able to use it sensibly again in the next cycle.
  • the subject of the invention can be used in a sensible manner in all machines for earthworks, in particular cable excavators, hydraulic excavators, backhoe and loading shovel excavators, the rocker depending on the particular device either being shifted to a support frame as a one-piece component or a division of the equipment and the swiveling part Part is made, each stored separately on a trestle and are connected to one another by corresponding connecting elements, such as ropes, chains or hydraulic cylinders.
  • FIGS. 1 and 2 show a schematic diagram of a hydraulic excavator 1 designed as a loading shovel excavator, which is essentially composed of the following components: an undercarriage 3 connected to a crawler chassis 2, a slewing ring 4, a stationary uppercarriage part 5 together with the driver's cab 6, the uppercarriage 5 being pivotable about the vertical axis 7 relative to the undercarriage 3.
  • a pivotable part 10 consisting of the components motor 8, counterweight 9 and the hydraulic system, not shown here, is connected to the work equipment 11, forming a kind of rocker, which carries the loading shovel 12 in the region of its free end.
  • the components 10 and 11 can thus be pivoted about a common horizontal axis 13, which is only indicated here, but at the same time can be rotated about the vertical axis 7 together with the stationary superstructure part 5.
  • the zero position of the pivotable part 10 is indicated by the dashed line 14 and the vertical distance between this zero position 14 and the upper edge 14 'of the undercarriage 3 is denoted by V.
  • V the vertical distance between this zero position 14 and the upper edge 14 'of the undercarriage 3
  • a swivel angle alpha of more than 45 ° can be achieved.
  • the division of the pivot angle alpha is approximately 1/2, ie the pivot angle of the pivotable part 10, based on the zero position 14, is twice as high as down.
  • the distance a from the center of gravity 15 of the pivotable part 10 to the tilting axis referred to in this illustration as the tipping point 35 forms the ratio to the distance b from the center of gravity 16 of the equipment 11 to the tipping point 35 a / b> 1.

  • the pivotable part 23, which is only indicated here, can be pivoted about the horizontal axis 24 of the support bracket 22 and the equipment 26 which interacts with the backhoe bucket 25 can be pivoted about the horizontal axis 27 of the support bracket 21.
