The invention relates to the technical field of engineering machinery gravity center adjustment, in particular to a gravity center adjusting device and engineering machinery. The gravity center adjusting device comprises a balance weight mechanism, a support, a translation supporting mechanism and a telescopic driving mechanism, the two ends of the support are in pivot joint with the engineering machine and the balance weight mechanism respectively, and the translation supporting mechanism is constructed to assist the support in supporting the balance weight mechanism to move. The telescopic driving mechanism is configured to drive the counterweight mechanism to move relative to the engineering machinery in a telescopic motion mode. During use, the telescopic movement of the telescopic driving mechanism can drive the counterweight mechanism to be close to or away from the engineering machinery at any time. The translation support mechanism can provide effective auxiliary support when the counterweight mechanism moves, so that the counterweight mechanism can move more stably. A telescopic beam type structure is not needed to drive the counterweight mechanism to be close to or away from the engineering machinery, and various defects caused by the fact that a telescopic beam is adopted to control the counterweight to move are avoided.
本申请涉及工程机械重心调节技术领域,具体涉及重心调节装置和工程机械。其中重心调节装置包括配重机构、支架、平移支撑机构和伸缩驱动机构,支架的两端分别与工程机械和配重机构枢接,平移支撑机构构造为辅助支架支撑配重机构进行移动,伸缩驱动机构构造为以伸缩运动驱动配重机构相对于工程机械进行移动。在使用时,伸缩驱动机构的伸缩运动可以随时驱动配重机构靠近工程机械或者远离工程机械。平移支撑机构能够在配重机构移动时提供有效的辅助支撑,使得配重机构能够更加稳定地运动。本申请无需采用伸缩梁式的结构来驱动配重机构靠近或远离工程机械,避免了采用伸缩梁控制配重移动而导致的各类缺陷。
