The invention relates to the technical field of crane maintenance equipment, and particularly discloses a crane overload protection device which comprises a base fixedly mounted at the top of a standard knot, a disc-shaped mounting table is arranged above the base, and a crane is fixedly mounted on the upper surface of the mounting table. The reinforcing mechanism is fixedly mounted in the base; and the auxiliary mechanism is fixedly mounted in the reinforcing mechanism. Through cooperation of a bearing ring and a rotating column, a rotating cover can rotate in the downward moving process, and meanwhile three rotating discs fixedly connected with a supporting column are arranged, so that the rotating discs synchronously rotate on a stable disc along with rotation of the rotating cover; through the double-layer stable structure, the gravity center of the crane is always kept vertical during working, so that the working stability of the crane is greatly improved, and the safety of a working environment is effectively improved.

    本发明涉及起重机维护设备技术领域,具体公开了一种起重机的超载保护装置,包括底座,所述底座固定安装在标准节的顶部,所述底座的上方设置有安装台,其中安装台设置为圆盘状,且起重机固定安装在安装台的上表面,还包括:加强机构,所述加强机构固定安装在底座的内部;辅助机构,所述辅助机构固定安装在加强机构的内部。通过承载环和转动柱的配合使得转动罩在下移过程中亦可以进行转动,同时通过设置与支撑柱固定连接的三个转动盘使得转动盘随着转动罩的转动在稳定盘上进行同步转动,通过双层级稳定结构使得起重机在工作时重心始终保持垂直,极大地提高了起重机工作时的稳定性,有效提高工作环境的安全性。
