The invention relates to the technical field of engineering machinery, and discloses a counterweight moving device and an operation machine, and the counterweight moving device comprises a first support, a second support, a counterweight and a driving part. The counter weight can slide on the first support and the second support, and the driving piece is used for driving the counter weight to move in the direction close to or away from the rotary table. The second support can be switched between a folded state and an unfolded state, and in the unfolded state, the second support is flush with the first support. The second support can be rotationally switched between the folded state and the unfolded state relative to the first support, so that when the second support is folded, the length of the whole vehicle is shortened, the road driving requirement is met, and potential safety hazards in the driving process are reduced; when the second support is unfolded, the driving piece can drive the balance weight to slide on the first support and the second support, the distance between the gravity center of the balance weight and the rotation center of the rotary table is adjusted, and therefore under the condition that the weight of the balance weight is not increased, the lifting performance of equipment is greatly improved, and the stability of the whole machine is improved.
本发明涉及工程机械技术领域,公开了一种配重移动装置及作业机械,该配重移动装置包括第一支架、第二支架、配重和驱动件。配重能够在第一支架和第二支架上滑动,驱动件用于带动配重向靠近或远离转台的方向移动。第二支架可在收起状态和展开状态之间切换,且在展开状态下,第二支架与第一支架平齐设置。通过第二支架能够相对于第一支架在收起状态和展开状态之间转动切换,从而在收起第二支架时,缩短整车长度,满足道路行驶要求,减少行驶过程中的安全隐患;在展开第二支架时,驱动件可带动配重在第一支架和第二支架上滑动,调整配重重心和转台回转中心间的距离,以在不增加配重重量情况下,大幅度提升设备起重性能,提升整机稳定性。
