Radiation scanning inspection apparatus

A radiation scanning inspection apparatus. The apparatus is provided with a working state and a transportation state, and comprises a base part, wherein the base part comprises a first longitudinal part (1) and a second longitudinal part (2) that are positioned on two opposite sides of the radiation scanning inspection apparatus; a main beam (3), wherein the main beam is arranged above the base part, and the height of the main beam in the working state is greater than that in the transportation state; a lifting device (62) arranged on the base part and used for lifting the main beam (3) when the working state and the transportation state are switched; and a support body (61), wherein the support body can be separated relative to the base part, is arranged between the main beam (3) and the base part in the working state, and is separated from the base part in the transportation state, such that the main beam (3) is directly connected to the base part. According to the inspection apparatus, disassembly and assembly of the apparatus are reduced, when the apparatus is switched from the transportation state to the working state, various tedious calibration operations do not need to be carried out, and state switching is flexible and convenient.
