Definitions

  • the present invention relates to a transhipment apparatus having an envelope boom and a cabin boom, wherein the cabin boom comprises a first and a second arm, which are articulated to each other via a connecting element, and a first actuator for moving the first arm.
  • handling equipment for example for wood, scrap or any other goods, but also to understand excavators and cranes.
  • the envelope boom can be used to transfer the corresponding goods, while the cabin jib serves to adjust the position of the driver's cab. This gives the driver an improved view of the work area, such as hatches, railway carriages or the like.
  • the cabin boom has for this purpose the articulated arms, via which the position of the car relative to the handling device is adjustable. The improved visibility allows more precise and faster work cycles.
  • the handling equipment usually has an envelope boom and a separate cabin boom, which can be moved independently of each other.
  • the envelope boom is usually arranged on the superstructure, which is rotatable relative to the undercarriage.
  • the cabin boom is usually also hinged to the uppercarriage of the handling unit and laterally offset from the envelope boom. At its free end, the cabin boom carries the driver's cab, which is movable relative to the superstructure.
  • Object of the present invention is therefore to provide a handling device according to the preamble of claim 1, which has an improved distribution of forces and Verstellgeometrie.

  • a handling device in which, according to the invention, the first and the second arm are each articulated on the connecting element via separate pivot axes.
  • the handling devices according to the invention in order to achieve different reach heights or ranges, only the arms must be extended or shortened, while the kinematics with the actuators can basically remain the same. Here at most the piston diameter of the hydraulic cylinders used as actuators must be adapted. Thus, the handling device according to the invention can be adapted with minimal design effort for different operating conditions with respect to the range or reach.
  • the actuator of the second arm is arranged on the underside of the second arm.
  • this actuator is charged by the weight of the cabin only to pressure, so that here also results in a larger effective area. Also, the cramped space within the parallel links are avoided.
  • the actuators of the first and / or the second arm are loaded by the weight of the cabin to pressure. This has the advantages already mentioned above regarding the force dissipation and the adjustment geometry.
  • the driver's cab in the handling device according to the invention by force fit forcibly guided parallel or at a certain angle to the ground.
  • the orientation of the cabin during movement of the cabin boom must not be readjusted, but is done automatically by positive engagement. The driver can thus bring the cabin in the desired position without changing the angle of the car to the ground.
  • the first and / or the second arm designed as a parallel link. This allows in a relatively simple manner a forced parallel guidance of the driver's cab.
  • the first and / or the second arm of the cabin boom according to the invention comprises at least one support element which has a closed box profile. This results in a sturdy construction which is lightweight at the same time yet stiffly responsive to bending and torsional loading.
  • the first and / or the second arm is designed as a parallel link and comprises a bottom arranged main bearing element, which has a closed box profile. So takes over this main bearing element the main load, and the coupling rods and the connecting element can be made simpler and lighter in weight.
  • the first and / or the second arm of the cabin boom designed as a parallel link, wherein the arm associated with this actuator from outside of the parallelogram engages the lower arm.
  • the first and / or the second arm has in its interior at least one hollow profile for receiving the cables or hoses running to the driver's cab.
  • these can advantageously run within the closed box profile.
  • the connecting element according to the invention has a joint whose pivot axis is perpendicular to the pivot axes of the first and / or the second arm.
  • the cabin can not only be adjusted with respect to the height and the boom width, but can also be pivoted laterally.
  • z. B. the lateral distance between the cabin jib and the cargo handling boom are increased, which may be necessary just for bulky Umschlaggut to still get an optimal view of the loading point.
  • the pivot axis of the joint runs in the vertical direction.
  • the joint of the connecting element is associated with an actuator.
  • the cabin can then be pivoted accordingly.
  • the hinge of the connecting element connects a first and a second part of the connecting element articulated to each other, wherein the first and the second arm are articulated respectively on the first and on the second part of the connecting element.
  • the first and the second arm are each articulated via separate pivot axes on the connecting element and also the actuator is not arranged between the two arms.
  • the connecting element has at least five separate pivot axes, in each case two for the arms of the cabin boom designed as parallel links and one for the actuator of the first arm.
  • the three bearing points for storage and adjustment of the first arm can be arranged arbitrarily to the two bearing points of the second arm, so that the movement and Verstellgeometrie the boom can be arbitrarily adapted to the application.
  • the cabin jib has a docking position on the handling device, in particular on the uppercarriage of the handling device. So the driver z. B. for maintenance work on the transhipment device or the superstructure by driving the cab in the docking position.
  • the cabin can be lowered by the cabin boom to the ground level.
  • the driver can either get on the ground from the ground, or he can use the cabin boom to transport spare parts on the handling device or on the superstructure.
  • the handling device advantageously has a platform for the transport of material, which is arranged on the cabin. This platform allows even larger elements to be transported with the cabin jib to the handling unit.
  • Access to the cab takes place either from the ground when the cab is lowered to ground level or in the docking position on the superstructure. It is also conceivable that the cabin boom still has a further access position, which allows easy access to the driver's cab.
  • FIG. 1 shows an embodiment of the cargo handling apparatus according to the invention with an envelope boom 1 and a cabin boom 2, which are arranged on the uppercarriage 5 of the handling device according to the invention.
  • the handling device is a wheeled excavator, which can be moved over the undercarriage 6.
  • the present invention can also be used for crawler excavators and other material handlers.
  • the envelope boom 1 in this case has two articulated arms, which can be moved via corresponding actuators. Depending on the application, a corresponding gripper is then attached to the top of the turn-up jib with which the material to be handled can be gripped.
  • Envelope 1 and cabin jib 2 are next to each other so arranged on the superstructure 5, that the movement planes of the two arms substantially are arranged parallel to each other.
  • the superstructure 5 is rotatably arranged in the envelope device shown on the undercarriage 6, so that both the envelope jib and the cabin jib, which are both hinged to the superstructure 5, are rotated by rotation of the upper carriage 5 in the same way.
  • the cabin boom 2 comprises a first arm 10 and a second arm 20, which are connected via a connecting element 30 hinged together.
  • the first arm 10 carries the driver's cab 3 of the handling device.
  • a support bracket 4 is arranged on the first arm 10, which is designed in an L-shape and on which the driver's cab 3 is mounted.
  • the second arm 20, however, is hinged on the handling device, here on the superstructure 5.
  • the first arm 10 is moved via an actuator 15, the second arm 20 via an actuator 25. Both actuators are designed as a hydraulic cylinder.
  • the first actuator 15 is articulated to move the first arm 10 via a pivot point 33 on the connecting element 30, which is arranged below the articulation points 31 of the first arm 10.
  • the first actuator 15 is only loaded on pressure.
  • first arm and the second arm 20 are articulated via respective separate pivot axes 31 and 32 on the connecting element.
  • first arm 10 and the second arm 20 have no common pivot axes, in turn, the adjustment and movement geometry of the cabin boom 2 can be optimally adjusted.
  • the actuator 25 of the second arm 20 is disposed below the second arm 20, so that this is also loaded only by pressure.
  • the first and the second arm of the cabin boom 2 are both designed as a parallel link, so that the driver's cab is positively guided by means of positive engagement parallel to the ground.
  • the first arm 10 consists of a main support element 12 and a coupling rod 10 which are each articulated via articulation points 11 on the support bracket 4 and via articulation points 31 on the connecting element 30.
  • the second arm 20 consists of a main support member 22 and a coupling rod 23 which are articulated via articulation points 21 on the superstructure 5 and articulation points 32 on the connecting element 30. The alignment of the articulation points 21 of the second arm 20 on the superstructure 5 to each other results automatically from the desired boom width and height of the cabin boom.
  • the articulation points 21 are therefore arranged as possible in a horizontal line, whereas if a large boom width is required, the articulation points 21 are arranged more strongly in a vertical line.
  • the oblique arrangement shown here is therefore a compromise of boom height and boom width.
  • the range of movement of the boom according to the invention can also be adjusted accordingly by the orientation of the articulation points 31 of the first arm 10 on the connecting element.
  • the use of separate articulation axes 31 and 32 of the first and second arms on the connecting element 30 results in increased flexibility with which the desired radii of movement can be easily achieved.
  • the main support members 12 and 22 are embodied according to the invention as closed box sections, which gives them increased stability with a lightweight construction. Likewise, cables and hoses to the cab can be passed through the hollow sections in the main support members 12 and 22.
  • the first arm 15 associated with the first arm 15 is articulated via an articulation point 33 on the connecting element 30, which is located below the articulation points 31 of the main support member 12 and coupling rod 13.

  • the platform 8 on the superstructure 5 also has a railing 40 and can also be reached from the undercarriage 6 via a ladder 41.
  • FIG. 5 shows a second embodiment of the handling device according to the invention, which differs from the first embodiment only in the embodiment of the connecting element 30.
  • the connecting element 30, which can be seen enlarged again on the right in individual views, has a joint 34, the pivot axis of which is perpendicular to the articulation axes 31 and 32 of the first and second arms.
  • the pivot axis 34 is arranged vertically, the first arm 10 of the cabin boom and thus also the driver's cab itself can pivot laterally against the second arm 20, so that the cabin of the in FIG. 5 not shown Envelope boom, which would be arranged in the picture behind the cabin boom, swing away.
  • the connecting element has an actuator 35, via which the joint 34 can be moved.
  • the connecting element 30 in this case has a first part 38 and a second part 39, which are pivotally connected to each other via the hinge 34.
  • first part 38 On the first part 38 are the articulation points 31 of the first arm 10 and the articulation point 33 of the first actuator 15.
