The invention relates to the technical field of counterweight equipment, in particular to a movable counterweight device and engineering machinery. The movable balance weight device comprises a balance weight frame, a first balance weight, a second balance weight and a displacement driving mechanism, the first balance weight and the second balance weight are connected to the two opposite sides of the balance weight frame respectively, and the displacement driving mechanism synchronously drives the first balance weight and the second balance weight to rotate at a constant speed relative to the balance weight frame. During application, the first counter weight and the second counter weight can be driven to rotate simultaneously and synchronously through the displacement driving mechanism, and when the first counter weight and the second counter weight rotate, adjustment of the gravity center is achieved. Meanwhile, the first balance weight and the second balance weight which rotate at a constant speed can enable the gravity center transfer speed to be more uniform, and hidden risks such as unbalance loading and unbalance caused by fast and slow gravity center change are avoided.

    本申请涉及配重设备技术领域,具体涉及可动式配重装置和工程机械。该可动式配重装置包括配重架、第一配重、第二配重以及变位驱动机构,第一配重和第二配重分别连接在配重架的相对两侧,变位驱动机构同步驱动第一配重和第二配重相对于配重架进行匀速转动。在应用时,通过变位驱动机构可以同时、同步地驱动第一配重和第二配重转动,当第一配重和第二配重转动时便实现了重心的调节。同时,匀速转动的第一配重和第二配重能够使得重心转移的速度更均匀,避免重心变化时快时慢带来的偏载和不平衡等隐性风险。
