The invention relates to the technical field of engineering machinery, and provides a gravity center position adjusting device, a counterweight device and an operation machine.The gravity center position adjusting device comprises a fixed seat, a rotating seat, an eccentric counterweight, a first driving mechanism and a second driving mechanism, and the fixed seat is connected with a vehicle body; the rotating seat is rotationally connected with the fixed seat, the rotating axis is a first axis, the eccentric balance weight is rotationally connected with the rotating seat, the rotating axis is a second axis, the first axis and the second axis are both perpendicular to the bearing surface of the vehicle body, a gap is formed between the second axis and the first axis, and a gap is formed between the gravity center of the eccentric balance weight and the second axis; the first driving mechanism can drive the rotating seat to rotate relative to the fixed seat; the second driving mechanism can drive the eccentric balance weight to rotate relative to the rotating base. According to the arrangement, rotation of the rotating base and the eccentric balance weight is combined, the adjusting range of the gravity center position of the eccentric balance weight is enlarged, and the problem that in the prior art, the gravity center position of a balance weight can only be adjusted in the front-back direction of a vehicle body is solved.
本发明涉及工程机械技术领域,提供一种重心位置调整装置、配重装置及作业机械,其中,重心位置调整装置包括固定座、转动座、偏心配重、第一驱动机构和第二驱动机构,固定座与车体连接;转动座与固定座转动连接,转动轴线为第一轴线,偏心配重与转动座转动连接,转动轴线为第二轴线,第一轴线和第二轴线均垂直于车体的承载面,第二轴线与第一轴线之间具有间距,偏心配重的重心与第二轴线之间具有间距;第一驱动机构能够驱动转动座相对于固定座转动;第二驱动机构能够驱动偏心配重相对于转动座转动。如此设置,结合转动座和偏心配重的转动,增加了偏心配重的重心位置的调整范围,解决现有技术中的配重的重心位置仅能够沿车体的前后方向调整的问题。
