and/or a second limit groove matched with the outer ring chassis is formed in one side, close to the outer ring chassis, of the stiffening beam.

3. The base structure according to claim 2, wherein a track mounting part for providing a moving path for a moving mechanism for driving the rotating platform to move is arranged at one end of the reinforcing beam away from the chassis, and the track mounting part is arranged in parallel with the inner ring chassis and/or the bearing support frame;

and a third limit groove matched with the track installation part is formed in one end, close to the track installation part, of the stiffening beam.

4. A base structure as claimed in claim 2 or claim 3, wherein the stiffening beams are arranged in circumferentially spaced apart and equally spaced apart relationship along the central axis of the chassis and extend from the central axis of the chassis to the outer edge of the chassis.

5. The base structure of claim 4, wherein the reinforcement beams include a plurality of first reinforcement beams and a plurality of second reinforcement beams arranged at intervals in sequence along a circumferential direction of the chassis, the chassis includes a chassis body having a square shape,

the plurality of first stiffening beams extend outwards from the central axis of the chassis to the vertex of the chassis body, where two adjacent frames are connected, and the plurality of second stiffening beams extend outwards from the central axis of the chassis to the frames of the chassis body and are perpendicular to the frames.

6. The base structure of claim 5 wherein the chassis comprises an outer ring chassis and an inner ring chassis,

and, keep away from the backup pad that is equipped with the same central axis and set up in parallel with the inner circle chassis in the one end of chassis at first stiffening beam and second stiffening beam, the backup pad includes:

the central supporting plate is arranged at the position, close to the central axis of the chassis, of the first reinforcing beam and/or the second reinforcing beam;

and/or the outer ring support plate encloses the central support plate.

7. The base structure of claim 5, wherein a supporting portion extending from the frame toward the central axis of the chassis is provided on the frame of the chassis body, and the supporting portion and the second reinforcing beam are vertically provided.

8. The base structure of claim 5 wherein the reinforcement beams further comprise a plurality of transverse reinforcement beams disposed between the first reinforcement beam and its adjacent second reinforcement beam, the plurality of transverse reinforcement beams and the first reinforcement beam and the second reinforcement beam are each fixedly connected, and the distance between each transverse reinforcement beam and the central axis of the chassis at the junction of the first reinforcement beam and the second reinforcement beam is equal.

9. The base structure of claim 8 wherein a rail mounting portion is provided at an end of the stiffening beam remote from the chassis to provide a path of movement for the movement mechanism that moves the rotary platform, the rail mounting portion being provided on a side of the transverse stiffening beam remote from the chassis.

10. The base structure of claim 5, wherein a reinforcing rib which is perpendicular to the chassis body and has the same extending direction as the first reinforcing beam and a reinforcing angle which is arranged at one end of the reinforcing rib and/or the first reinforcing beam far from the chassis body are arranged at the vertex where two adjacent frames are connected in the chassis body.

11. A scanning device comprising a base structure according to any one of claims 1 to 10, a rotating platform arranged above the base structure and connected to the base structure by means of a bearing support, and a scanning column connected to the base and penetrating the base at its central axis.
