Embodiment Construction

[0022] figure 1 A large-scale manipulator according to the present invention is schematically shown, specifically a truck-mounted concrete pump, the whole of which is denoted by reference numeral 1 . Arranged on the chassis 2 is a mast base 3 which is rotatable about the vertical axis of the truck-mounted concrete pump 1 by means of a rotary drive (not shown). Hinged to the mast base 3 is an articulated mast, generally designated by reference numeral 4 , comprising four mast arms 5 , 6 , 7 and 8 in the exemplary embodiment shown. The first mast arm 5 is pivotally attached to the mast base 3 by a joint about a horizontal axis. The pivoting movement is achieved by a pivot drive (not shown for clarity). The remaining mast arms 6, 7 and 8 are respectively pivotably connected to respective adjacent mast arms by pivot joints about mutually parallel horizontal axes. The pivoting movement is likewise effected in each case via a pivot drive (not shown). The pivot drives each have o...

Abstract

The invention relates to a large manipulator (1), in particular a truck-mounted concrete pump, with a mast pedestal (3), which is rotatable about a vertical axis by means of a rotary drive and which is arranged on a frame (2), an articulated mast (4) which comprises two or more mast arms (5, 6, 7, 8), wherein the mast arms (5, 6, 7, 8) are each pivotably movably connected via articulated joints tothe respective adjacent mast pedestal (3) or mast arm (5, 6, 7, 8) by means of a pivot drive, a control unit controlling the drives for the mast movement, and a mast sensor system for detecting the position of at least one point of the articulated mast (4) or a pivot angle ([phi]1, [phi]2, [phi]3, [phi]4) of at least one articulated joint. The large manipulator is characterized in that the control unit (17) is additionally designed to limit the speed of the mast movement based on the output signal of the mast sensor system. In addition, the invention relates to a method for controlling the movement of an articulated mast (4) of a large manipulator (1), in particular a truck-mounted concrete pump.

Description

technical field [0001] The invention relates to a large manipulator, especially a truck-mounted concrete pump, which has: a mast base, which can be rotated around a vertical axis by a rotary drive, and is arranged on a chassis; an articulated mast, which includes two or more a plurality of mast arms, wherein the mast arms are connected to respective adjacent mast bases or mast arms via articulated joints so as to be pivotable by means of pivot drives, respectively; a control device which actuates the drives to for mast movement; and a mast sensor arrangement for detecting the position of at least one point of the articulated mast or the pivot angle of at least one articulated joint. [0002] The invention also relates to a method for controlling the movement of a large manipulator, in particular an articulated mast of a truck-mounted concrete pump. Background technique [0003] Large manipulators are known in various embodiments in the prior art. A large robot arm with an ...
