Embodiment Construction
[0047] according to figure 1 The illustration of shows schematically a large robot 1 configured as a truck-type concrete pump with a chassis 2 on which a vertical axis 16 is arranged around the large robot 1 by means of a hydraulic rotary drive 6 Rotating turntable 3. An articulated mast 4 , generally designated by reference numeral 4 , is hinged to the turntable 3 , and in the exemplary embodiment shown, said mast comprises four mast sections 5 a , 5 b , 5 c and 5 d . The first mast section 5a is movably arranged on the turntable 3 via a joint pivotally about a horizontal axis. The pivoting movement is achieved by the pivot drive 6a. The remaining mast sections 5b, 5c and 5d are pivotally movable connected with the respective connected mast sections 5a, 5b, 5c, 5d via articulated joints about horizontal axes parallel to each other. The pivoting movement also affects the pivot drives 6a, 6b, 6c, 6d respectively. Pivot drives 6a, 6b, 6c, 6d each comprise one (or more) hydra...

The invention relates to a large manipulator (1), in particular a truck-type concrete pump, comprising: a turntable (3), which can be rotated around a vertical axis by means of a rotary drive and arranged on a chassis (2); an articulated a mast (4) comprising two or more mast sections (5a, 5b, 5c, 5d), wherein said mast sections (5a, 5b, 5c, 5d) are respectively driven by means of drives (6, 6a, 6b , 6c, 6d) are pivotally movably connected to corresponding adjacent turntables (3) or mast sections (5a, 5b, 5c, 5d) via hinged joints; control means (7) for mast movement, which Drives said drives (6, 6a, 6b, 6c, 6d) in normal operation; and a mast sensor system for detecting the position of at least one point of said articulated mast (4) or the pivot of at least one articulated joint Swivel The problem solved by the invention is to be able to bring an articulated mast from its fully folded state to its desired working position in the shortest possible time. Furthermore, even in the event of a failure of said mast sensor system, it should be ensured that the displacement speed of the drives complies with legal standards. To this end, the invention proposes that said control means (7) are designed to limit the speed of movement of the mast, since the mast speed is limited to a maximum value according to the instantaneous output signal of the mast sensor system, wherein said drive (6, 6a, 6b, 6c, 6d) are manually controllable in the emergency mode of operation, wherein at least one limiting device (11, 12, 13, 14) is provided which The displacement speed of at least one of (6, 6a, 6b, 6c, 6d) is limited to a fixed predefined maximum value. The invention also relates to a method for controlling the movement of an articulated mast of a large manipulator.
Description
technical field [0001] The invention relates to a large manipulator, in particular a truck-type concrete pump, with: a turntable, rotatable about a vertical axis by means of a rotary drive, arranged on a chassis; an articulated mast comprising two or two or more mast sections, wherein each of said mast sections is pivotably and movably connected to a corresponding adjacent turntable or mast section via an articulated joint by means of a drive each; a control device for driving the drive in normal operation of the movement of the mast; and a mast sensor system for detecting the position of at least one point of said articulated mast or the pivot angle of at least one articulated joint. [0002] Furthermore, the invention relates to a method for controlling the movement of a large manipulator, in particular an articulated mast of a truck-type concrete pump. Background technique [0003] Large manipulators are known in various configurations in the prior art. For example, WO ...
