The invention discloses a slip ring drive structure for CT (computed tomography). The slip ring drive structure comprises a slip ring bracket, a slip ring, a first drive device, a second drive device and a transmission device, wherein the slip ring is rotatably fixed on the slip ring bracket the transmission device is coaxially and fixedly connected with the slip ring the first drive device and the second drive device are fixed on the slip ring bracket the first drive device and the second drive device are in transmission connection with the transmission device the driving directions of the first drive device and the second drive device are the same. The slip ring drive structure for CT can be used for greatly shortening the starting time of the slip ring, improving the starting speed of the slip ring of safety inspection CT, so that the package inspection time of the safety inspection CT is improved. After the slip ring is started, one motor stops electrifying, and the power of the other motor is relatively low, so that the rotary energy consumption of the slip ring of the safety inspection CT can be lowered.
