Title:
CONCRETE PUMP TRUCK BOOM CONTROL SYSTEM AND METHOD, AND CONCRETE PUMP TRUCK
Document Type and Number:
WIPO Patent Application WO/2022/160859
Kind Code:
A1
Abstract:
A concrete pump truck boom control system and method, and a concrete pump truck. The boom control system comprises a boom provided with a plurality of sections of arms (1), a plurality of luffing drive components (2), a plurality of inclination angle measurement components (3), a rotation angle measurement component (4) and a controller (6), wherein the adjacent arms (1) are rotatably connected in the same vertical plane, each luffing drive component (2) is disposed between the two adjacent arms (1), and the plurality of inclination angle measurement components (3) are installed at beginning ends of the plurality of sections of arms (1) in a one-to-one corresponding manner, and configured to measure an accelerated speed and an angular speed of each of the beginning ends in three orthogonal directions when the located arms (1) vibrate; the rotation angle measurement component (4) is configured to measure a rotation angle of the boom in a horizontal plane; and the controller (6) is configured to obtain a posture of each of the plurality of sections of arms (1) according to a measurement value of each of the plurality of inclination angle measurement components (3) and a measurement value of the rotation angle measurement component (4), so as to obtain a deformation offset of each of the plurality of sections of arms (1) relative to a target position, and configured to enable the corresponding luffing drive component (2) to act to adjust the position of each of the arms (1) according to the deformation offset, so that the boom can be kept at the target position. Further disclosed are a pump truck provided with the boom control system, and a control method of the boom control system. The control system enables the boom to be still kept at the target position during vibrating.
