The invention discloses a cargo transfer transporting device. The cargo transfer transporting device comprises a cargo bin for containing cargoes and a bearing frame for transporting the cargo bin. Aloading cavity with a rightward opening is formed in the cargo bin. First sliding grooves which are bilaterally symmetric and are provided with downward openings are formed in the front end wall and the rear end wall of the loading cavity, and sliding columns are mounted in the first sliding grooves in a vertical sliding mode. Upper permanent magnets are fixedly arranged at the upper ends of the sliding columns, lower permanent magnets are fixedly arranged at the lower ends of the sliding columns, and locking grooves which are communicated left and right are formed in the lower ends of the sliding columns. First electromagnetic devices are fixedly arranged in the upper end walls of the first sliding grooves, a fixed conductive block electrically connected with the first electromagnetic devices is fixedly arranged in the left end face of the cargo bin, and a positioning groove stretching left and right is formed in the bottom end face of the cargo bin.
