Device for preventing plane trolley from turning over for coiled material transfer

The utility model relates to the technical field of coiled material transfer, in particular to a planar trolley rollover prevention device for coiled material transfer, which comprises a device body, a hook is fixedly connected to one side outside the device body, clamping mechanisms are fixedly connected to the top surface of the device body, and the clamping mechanisms are symmetrically distributed about the vertical center line of the device body. The device comprises a device body, a lifting mechanism and a gravity layer are arranged in the device body, a supporting column is movably connected to the interior of the lifting mechanism and located at the bottom of the device body, and motors are fixedly connected to the interior of the lifting mechanism and the interior of the gravity layer respectively. The supporting column is controlled by the lifting mechanism to be in a static state for supporting and bearing, the stress mechanism is driven by the gear mechanism to enhance the center gravity according
