The invention discloses a box body anti-tipping device and method and an electric excavator. According to the specific scheme, a lock cylinder mounting part is used for mounting a lock cylinder on a rotary table; the lock cylinder connecting part is fixedly connected with the lock cylinder; one end of the lock cylinder rotating spring is connected with the lock cylinder connecting part, and the other end is connected with the turntable bottom surface; one end of the flexible cable is connected with the lock cylinder connecting part, and the other end is connected with a mounting plate on the turntable; the telescopic part is installed on the rotary table located above the flexible cable, an operator opens the telescopic part, the telescopic part compresses the flexible cable downwards, so that the lock cylinder is driven to rotate along with the lock cylinder connecting part, the top structure of the lock cylinder rotating by a preset angle cannot penetrate through a limiting hole of the battery replacing box, and the battery replacing box is fixed to the rotary table. The step of manually rotating a bottom handle in the battery replacement process can be omitted, full-automatic battery replacement is achieved, and the problems that a driver forgets to operate, and consequently economic losses and even casualties are caused are solved.

    本发明公开了一种箱体防倾翻装置、方法及电动挖掘机,具体方案为:锁芯安装部件用于将锁芯安装在转台上;锁芯连接部件与锁芯固定连接;锁芯旋转弹簧的一端与锁芯连接部件相连,另一端与转台底面相连;柔性线缆的一端与锁芯连接部件相连,另一端与转台上的安装板相连;伸缩部件安装在位于柔性线缆的上方的转台上,操作员开启伸缩部件,伸缩部件向下压缩柔性线缆,从而带动锁芯跟随锁芯连接部件一起旋转,旋转预定角度后的锁芯顶部结构不能够穿过换电箱的限位孔,使得换电箱固定在转台上。本发明能够省略换电过程中手动旋转底部把手这一步骤,实现全自动换电,避免因司机忘记操作而引起经济损失甚至造成人员伤亡的问题。
