Definitions
- the invention relates to a large manipulator, in particular for truck-mounted concrete pumps, with one on one Frame, in particular a chassis arranged, about a substantially vertical axis of rotation by 360 ° rotatable means a drive unit drivable mast block, with a compound of at least three branches, preferably designed as a concrete distribution boom Articulated mast, which mast arms around each horizontal, opposite to each other kink axes the respectively adjacent Mastbock or Mastarm means each of a further drive unit limited pivotally are, and with at least one control lever having remote control device for driving the drive units, wherein the control lever in two mutually perpendicular Hauptstellraumen is adjustable back and forth, and wherein the Remote control device a controllable via the control lever, computer-assisted coordinate transmitter having for the drive units.
- Truck-mounted concrete pumps of this type are mobile work tools that can be used with the full 360 ° swiveling range of the trestles in the extended horizontal position of the articulated mast.
- the operator is responsible for controlling the truck-mounted concrete pump and positioning the concrete end hose on the last arm of the articulated mast. He has to operate more than two rotational degrees of freedom of the articulated mast on the associated drive units with movement of the articulated mast in non-structured three-dimensional workspace in compliance with the site boundary conditions.
- Proportional Funkfernstauerungen this operator activity was facilitated to the extent that the operator is no longer linked with a cable spatially with the truck-mounted concrete pump.
- the invention is based on the recognition that at a common control of the redundant Buckling axes of the buckling mast independent of the Rotary axis of the mast block with a single adjustment of the control lever an illustrative for the operator Stretching or shortening movement of the kink mast at a given height of the Knickmastspitze can be executed.
- the coordinate encoder in the one main actuating direction of the control lever the drive units of the bending axes independent from the drive unit of the rotary axis in each rotary position of the mast block under execution of a stretching or shortening movement of the buckling mast at a given height the Knickmastspitze are actuated and that the drive units the redundant buckling axes of Knickmasts each in accordance with an optional predetermined Off-swing characteristic can be actuated are.
- the drive unit of the axis of rotation of the Mastbocks independent of the drive units the bending axes under execution of a rotary motion of the buckling mast at a given height of the mast top actuated.
- the mast arms depend on their orientation to the gravitational axis on the one hand and from the on load acting on them (e.g., concrete in the production pipe) on the other hand more or less large bending and torsional moments are exposed to the location of the mast top given given pivot positions in the individual Falsified joints is, according to a preferred Embodiment of the invention proposed that the path-swing characteristic in the coordinate transmitter according to the attack on the individual fattening arms Load-dependent bending and torsional moments is modifiable. The same applies if to avoid of collisions in the movement space of the Knickmasts obstacles are overcome.
- the truck-mounted concrete pump shown in the drawing has a chassis 10, one near the front axle 12 and the cab 14 of the chassis 10th arranged mast block 16, one on the mast block 16 um a vertical axis of rotation 18 by means not shown Hydraulic rotary unit rotatable by 360 ° Articulated mast 20, one above a material feed bin 22 hydraulically powered concrete Concrete pump 24 and one via a diverter valve 26 to the concrete pump 24 connected delivery line 28 on.
- the articulated mast 20 has five mast arms 1, 2, 3, 4 and 5, which at the articulation A with the Mast block 16 and at the articulated joints B, C, D and E. about each horizontal bending axes pivotally with each other are connected.
- a remote control device which a radio remote control unit 80 separate from the chassis and one with the radio remote controller 80 via transceivers 36, 36 'via a bidirectional radio link 38 communicating vehicle-mounted control device 31 includes.
- the radio remote control unit 80 has several, designed as a control lever controls 34, 34 ', 34 ", each in two mutually perpendicular Main positions forward and backward under delivery be adjusted by control signals.
- the Control signals are sent over the bidirectional radio link transmitted to the vehicle-fixed transceiver 36 ' and in a data preparation stage 40 and a computer-aided coordinate generator 42 in coordinate signals for the power units 30 of the six Axes 18, A, B, C, D, E implemented.
- the size of the deflection of the control levers 34, 34 ', 34 " via a suitable sensor or electronics in speed-determining Signals are implemented.
- the drive units 30 all buckling axes A to E individually or in their entirety so controlled that the Buckling mast 20 in the plus direction a stretching movement and in the minus direction a shortening movement at constant Drehrage of the mastbuck 16 and at constant Height H of the articulated mast end above the ground 140 performs.
- Each bending axis A to E is within the coordinate transmitter 42 so controlled by software, that the articulated joints depending on path and time itself move harmoniously to each other.
- the invention relates to a large manipulator, in particular for truck-mounted concrete pumps.
- On a rack is one around one vertical axis of rotation 18 drivable mast block as well one composed of at least three fattening arms 1 to 5 Articulated mast arranged.
- the mast arms 1 to 5 of the kink mast are horizontal, parallel to each other Buckling axes A to E in pairs opposite to each adjacent Mastbock 16 or Mastarm 1 to 5 limited by a respective drive unit 30 pivotally.
- the actuation of the articulated mast takes place via a remote control device 30 with control levers 34,34 ', 34 ".
- the remote control device via the Control lever 34 controllable, computer-assisted coordinate encoder 42 for the drive units 30, about in the one main direction (+, -) of the Control lever 34, the drive units 30 of the bending axes A to E independent of the drive unit of Rotary axis 18 of the mast block 16 under execution of a Stretching or shortening movement of the kink mast 20 operable at a predetermined height H of the mast top are.
