The invention discloses a turnover device of a crane. The turnover device of the crane comprises a base and a turnover arm rotationally arranged on the base, wherein a driving mechanism connected withthe turnover arm and used for driving the turnover arm to swing is arranged on the base; a rotating assembly is installed on the base, and is connected with a power structure which is installed on the base and used for driving the rotating assembly and the driving mechanism to act; the power structure has a forward working state and a reverse working state; the power structure drives the rotatingassembly to act, and the rotating assembly winds a steel wire through a change wheel and a grooved wheel to drive a hanging piece to contract upwards, so that a heavy object hung on the hanging pieceis driven to move upwards; and meanwhile, the power structure further drives the driving mechanism to act, and the driving mechanism drives the turnover arm to swing and turn over, so that the functions of upward lifting or downward swinging and falling are achieved, and in the process of driving the heavy object to swing and lift, the lifting height of the heavy object is further increased through steel wire winding.

    本发明公开了一种吊车的翻转装置,包括底座和转动设置在所述底座上的翻转臂,在所述底座上安装有同所述翻转臂连接用于驱动所述翻转臂摆动的驱动机构;在所述底座上安装有旋转组件,所述旋转组件连接安装在所述底座上用于分别驱动所述旋转组件和所述驱动机构动作的动力结构,所述动力结构具有正向和反向两种工作状态;通过动力结构带动旋转组件动作,旋转组件借助换轮和槽轮缠绕钢丝,从而带动悬挂件向上收缩,从而带动与之挂设的重物跟随向上运动,同时动力结构还驱动驱动机构动作,驱动结构带动翻转臂摆动翻转,实现上扬吊运或下摆降落的功能,在带动重物摆动升降的过程中利用钢丝绕卷进一步提高重物的上抬高度。
