Problems solved by technology
When the vertical detection arm is unfolded to a predetermined position, but the driving device continues to apply a pulling force to the vertical detection arm, the vertical detection arm will twist around its own axis in the horizontal plane, so that the The detector will not be able to receive radiation accurately, which will lead to errors in the detection results and low detection accuracy

The invention relates to a scanning device and a vehicle-mounted radiation inspection system. The scanning device includes a horizontal support arm, a vertical probe arm, and a torque balance component. The vertical probe arm is rotationally connected with the horizontal support arm through a rotating shaft, has a folding position and an unfolding position relative to the horizontal support arm, and has a central axis perpendicular to the rotating shaft. The torque balance component is arranged on the two sides of the central axis. The vertical probe arm abuts against the horizontal support arm through the torque balance component in the unfolding position, so as to keep balance in the horizontal plane. The scanning device provided by the embodiment of the invention has high detection accuracy, and can improve the accuracy of detection.
Description
technical field [0001] The invention relates to the technical field of scanning detection equipment, in particular to a scanning device and a vehicle-mounted radiation inspection system. Background technique [0002] With the growth of global trade, the demand for containers is increasing day by day. More goods are transported and traded in containers. In order to avoid the situation where contraband such as weapons, explosives, illegal drugs or precious metals are hidden in the container, but at the same time the container cannot be opened for detection, the non-contact detection of the container by the ray scanning system can solve this problem well. A ray scanning system usually includes a horizontal support arm and a vertical detection arm. When it is necessary to use the ray scanning system for detection work, the vertical detection arm will be gradually expanded under the drive of the driving device. When the vertical detection arm is unfolded to a predetermined pos...
