The invention relates to a locking mechanism for an ultra-large tonnage conveying trolley. A bottom plate is arranged on the ultra-large tonnage conveying trolley, a shaft seat is fixedly arranged at one side of the bottom plate, a support frame is fixedly arranged at the other side of the bottom plate, the support frame is higher than the shaft seat, the middle part of a cylinder body of a locking oil cylinder is hinged to the top of the shaft seat, a swinging arm is in a V shape, one end of the swinging arm is hinged to the end part of the locking oil cylinder, the middle part of the swinging arm is hinged to the upper part of the support frame, and one side, near the swinging arm, of a locking disc is connected with the swinging arm through a pair of tension springs in symmetrical arrangement. The locking mechanism has the advantages that according to the technical scheme, the locking mechanism is mainly arranged inside a machine frame of the ultra-large tonnage conveying trolley, when large-scale materials are loaded on a conveying platform, in order to prevent safety accidents due to material slippage, firstly, the locking oil cylinder is forwards driven, and the swinging arm can be vertical, the locking disc ascends, so that the friction sheet can be butted against the bottom of the materials, and in addition, upward force is given to the materials, so that the friction is increased, and the effect of preventing the slippage is achieved.
