Embodiment Construction

[0030] figure 1 A large manipulator according to the present invention is schematically shown, that is, a vehicle-mounted concrete pump, which is denoted by reference numeral 1 as a whole. Within the scope of the present disclosure, working devices such as arms, booms, hoisting mechanisms, hoisting frames or masts are understood under the term large robot 1 . The large manipulator 1 comprises a deployable articulated mast 5 arranged around a vertical axis y 0 Rotating mast base 3. This rotation of the mast base 3 about a vertical axis is caused by a rotary drive 2 comprising a transmission and a hydraulic motor, preferably actuated via a proportional control valve. The articulated mast 5 is articulated on the mast base 3 and comprises a plurality, in the exemplary embodiment a total of four mast arms 6a, 6b, 6c, 6d which can be moved respectively by means of a corresponding one of the pivot drives 8a, 8b, 8c, 8d pivot relative to the adjacent mast arms 6a, 6b, 6c, 6d or the...

Abstract

The invention relates to a large manipulator (1), in particular a truck-mounted concrete pump, comprising a boom pedestal (3), which can be rotated about a vertical axis by means of a rotary drive (2)and which is mounted on a chassis (4), and an articulated boom (5) which comprises two or more boom arms (6a, 6b, 6c, 6d). The boom arms (6a, 6b, 6c, 6d) are pivotally connected to the adjacent boompedestal (3) or boom arm (6 a, 6b, 6c, 6d) via articulation joints (7a, 7b, 7c, 7d) by means of pivot drives (8a, 8b, 8c, 8d). The large manipulator also comprises a controller (9) which actuates thedrives (2, 8a, 8b, 8c, 8d) for the movement of the boom. The controller (9) is designed to autonomously move the articulated boom (5) from a starting position (A) of the articulated boom (5) into a specified target position (B) of the articulated boom (5) using a control sequence for actuating the drives (2, 8a, 8b, 8c, 8d). The invention additionally relates to a method for controlling the movement of an articulated boom (5) of a large manipulator (1), in particular of a truck-mounted concrete pump.

Description

technical field [0001] The invention relates to a large manipulator, especially a vehicle-mounted concrete pump, which has: a mast base, which can rotate around a vertical axis by means of a rotary drive, and which is arranged on a chassis; an articulated mast, It comprises two or more mast arms, wherein the mast arms are respectively pivotably and movably connected with corresponding adjacent mast bases or mast arms via hinged joints by means of a corresponding one of the pivot drives; and also has Control unit that actuates drives for mast movement. [0002] Furthermore, the invention 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 configurations in the prior art. For example, WO 2014 / 166637 A1 discloses a large manipulator with an articulated mast. WO 2014 / 166637 A1 proposes a large manipulator in which the c...
