Abstract: A radiographic inspection device and a method of inspecting an object are provided. The radiographic inspection device includes a support frame, where an inspection space applicable to inspect an object is formed within the support frame, and the inspection space has a first opening connecting to an outside; a transfer mechanism applicable to carry the object and move through the inspection space; a shielding curtain mounted at the first opening; and a driving mechanism. The driving mechanism includes: a driver mounted on the support frame; and a joint portion, where an upper end of the shielding curtain is connected to the joint portion. The driver is configured to synchronously drive two ends of the joint portion, so that the shielding curtain moves up and down with the joint portion to open or close the first opening.

Abstract: A radiographic inspection device and a method of inspecting an object are provided. The radiographic inspection device includes a support frame, where an inspection space applicable to inspect an object is formed within the support frame, and the inspection space has a first opening connecting to an outside; a transfer mechanism applicable to carry the object to move through the inspection space; a shielding curtain mounted at the first opening; and a driving mechanism mounted on the support frame and configured to drive the shielding curtain to move, so as to open or close the first opening. Since the driving mechanism drives the shielding curtain to rise or fall, it is possible to ensure that the lightweight object for inspection may smoothly enter the inspection space for subsequent radiographic scanning.

Abstract: A radiographic inspection apparatus and a vehicle-mounted security inspection system. The radiographic inspection apparatus includes a scanning device, where the scanning device includes: an upright framework; a slip ring rotatably provided on the upright framework; and a locking mechanism. The locking mechanism includes: a driving mechanism provided on the upright framework; and a contact portion provided on the driving mechanism to come into contact with an outer ring of the slip ring under a driving of the driving mechanism, so as to prevent the slip ring from rotating relative to the upright framework.
