Abstract:
A CT scanning device (100), comprising: a supporting frame (1); a sliding ring (2); a driving mechanism (3), configured to drive the sliding ring (2) to rotate with respect to the supporting frame (1); at least two annular rails (4), mounted on the outer periphery of the sliding ring (2); and at least two groups of supporting devices (5). Each group of supporting device (5) comprises at least two roller assemblies (51) which are arranged around the annular rail (4) and are suitable for supporting the sliding ring (2); each roller assembly (51) comprises a roller (511), and the rollers (511) are mounted on the supporting frame (1) and combined with the annular rail (4) so as to support the sliding ring (2); the roller (511) of at least one roller assembly (51) of the at least two roller assemblies (51) is combined with the annular rail (4) to prevent the sliding ring (2) from moving in the axial direction. The multiple rollers (511) having smaller outer diameters are used for supporting the sliding ring (2), so that a cantilever structure for supporting the sliding ring (2) can be omitted, and the rollers (511) are easy to be replaced after being damaged.
