Radiation scanning and detecting device for small and medium size vehicles

The invention relates to a radiation scanning and detecting device for small and medium size vehicles. The radiation scanning and detecting device for the small and medium size vehicles comprises a door frame, a radiation source, a detector, a supporting platform, a conveyer support, a circulation drag unit, a vehicle wheel guide unit and a hanging bridge unit. The method of the radiation scanning and detecting device for the small and medium size vehicles has the advantages that a top illuminate radiation source U-type detector arrangement mode is adopted, the flattening radiation detection relative to the vehicles is achieved, and image quality is improved effectively; detectors with high sensitivity are adopted, image resolution can achieve the level of package detection, and a security check inspector can identify guns, knives, explosive assemblies and other forbidden objects conveniently; a double-energy detection technology is adopted to detect the material characteristics of the articles inside the vehicles, the fact that the security check inspector can identify flammable and combustible dangerous goods is facilitated; trundles and foot margins are designed and mounted on vehicle conveying devices and check channels, equipment is convenient to mount, debug and move, non-fixed type mounting with the ground is achieved, and the floor of a site cannot be damaged.
