Disclosed is an inspection system for inspecting a cargo by using radiation, comprising: a main plate conveyor; a radiation scanning unit that spans said main plate conveyor and is provided above said main plate conveyor, for scanning the cargo provided on the main plate conveyor; auxiliary conveyors that are provided at the front end and rear end of said main plate conveyor, respectively, so as to load the cargo to be inspected onto said main plate conveyor and to unload the inspected cargo from said main plate conveyor; and lifting devices for lifting said auxiliary conveyors. The inspection system according to the present invention occupies less area, has simple corollary equipments, a lower operating cost, and excellent compatibility, and can be widely applied.

Radiation inspection system

A combined mobile container inspection system, comprising: a radiation source; a chassis; a rotatable deck provided at an end of the upper surface of said chassis and rotatable with respect to said chassis, provided with a parallelogram bracket formed by a hingedly-connected four-bar linkage mechanism, wherein the cross link of the parallelogram bracket extends to form a horizontal cross arm with detectors, the other end of said horizontal cross arm is connected with a vertical upright arm, which is vertical or parallel to said horizontal cross arm; and a sliding deck provided at the rear end of the rotatable deck and movable upwardly and downwardly, said sliding deck is provided, in turn, with the radiation source, the X-ray therefrom is always right in the face of the detectors provided in the horizontal cross arm and vertical upright arm, calibrator and collimator.

Combined mobile container inspection system with low target

An inspection system for air cargoes, in which an accelerator, a collimator, and a vertical detector arm are all mounted on the floor; detectors are provided within both the horizontal detector arm and the vertical arm; the accelerator, the collimator, the horizontal detector arm and the vertical detector arm are provided in a same plane; the horizontal detector arm is supported by the upper end of the collimator, the vertical detector arm and the horizontal detector arm are connected to each other and provided in the side opposite to the accelerator; a stable portal-shaped frame is formed by means of the collimator, the horizontal detector arm and the vertical detector arm; the conveying device is located under the horizontal detector arm, being perpendicular to the portal-shaped frame, the collimator is provided between the conveying device and the frame.

Inspection system for air cargoes or vehicles

A trailer of an automatically scanning-type radiation inspecting system used for large-sized object, comprising a trailer body provided with a bevel portion at a tail end of a top surface thereof and positioning recesses adaptive to lower portions of front wheels of a vehicle carrying objects to be inspected respectively, a plurality of pairs of guide wheels mounted to a bottom surface of the trailer body and can be supported and run on rails, connection rods provided at front and rear ends of the bottom surface of the trailer body and used for connecting to wire ropes of winches respectively, anchoring hooks provided at front and rear ends of the bottom surface of the trailer body and used for engaging with wedges arranged on the ground, and holding means provided at front and back sides of the positioning recesses and used for holding the front wheels of the vehicle in the positioning recesses during movement of the trailer. During operation of the trailer of present invention, the trailer pulls the vehicle carrying objects to be inspected to pass through the inspection passage smoothly while the front wheels of the vehicle are held in the positioning recesses on the trailer and rear wheels thereof roll over the ground. The trailer-conveying apparatus formed by the trailer of the present invention and winches occupies less land, being low in cost, simple in structure, reasonable in design, advantageous to shield the radiation, and easy to be maintained.
