CT inspection system

The present disclosure relates to CT inspection field, in particular to a CT inspection system. The CT inspection system provided by the present disclosure includes a rotating bracket, a scanning device and a rotation driving device, a rotation driving unit of the rotation driving device includes a support beam and two wheel driving mechanisms with drive wheels, the support beam is arranged in a swingable manner, the two wheel driving mechanisms are arranged on the support beam and located at the two sides of the swing center of the support beam, and the drive wheels drive the rotating bracket to rotate so as to cause the scanning device rotate during rotation. In the present disclosure, when one of the two wheel driving mechanisms located at the two sides of the swing center of the support beam bears relatively large load, the swingable support beam automatically distributes the load to the other one by swinging, so that each wheel driving mechanism bears the pressure in a relatively balanced manner, therefore a more stable rotation process of the rotating bracket is achieved, and thus the rotation stability of the radiation source device and the detection device that are driven to rotate by the rotating bracket is effectively improved.
