Abstract

A detection apparatus comprises a freely-movable integral framework provided with front wheels and rear wheels, characterized in that, a control portion and a scan portion, and a driving mechanism driving said framework to move are provided on said framework, wherein said framework is provided with a first interface for connecting to external power, so that said detection apparatus is driven by external power via the driving mechanism to perform detection while conducting detection on site, and wherein the semitrailer for mounting the framework is provided with a second interface connectable to a traction apparatus so as to connect the detection apparatus and the traction apparatus while carrying out site-changing transportation. Said detection apparatus is not affected by the alteration of the emission standards, has low failure rate and maintenance cost, has zero emission in the detection state, and is pollution-free.

Claims

1. A detection apparatus, comprising:

a freely-movable integral framework provided with front wheels and rear wheels,

characterized in that,

a control portion and a scan portion, and a driving mechanism for driving said framework to move are provided on said framework,

a first interface for connecting to external power is provided on said framework, so that said detection apparatus is driven by external power via the driving mechanism to perform detection while conducting detection on site.

2. The detection apparatus according to claim 1, characterized in that, said first interface is an interface for clean energy.

3. The detection apparatus according to claim 2, characterized in that, said traction apparatus is a universal tractor chosen according to the emission requirements.

4. The detection apparatus according to claim 1, characterized in that, said front wheel is a liftable steering axle.

5. The detection apparatus according to claim 1, characterized in that, said driving mechanism is a friction-wheel driving system.

6. The detection apparatus according to claim 5, characterized in that, said friction-wheel driving system includes a hydraulic cylinder, an electromotor and a friction-wheel, which are configured so that the friction-wheel is pressed tightly against the rear wheel or the front wheel of the framework while the hydraulic cylinder is extended, and the external power brings the friction-wheel to rotate.

7. The detection apparatus according to claim 6, characterized in that, a rotatable tray (9) is mounted on the framework, and the scan portion is mounted on said tray.

8. The detection apparatus according to claim 7, characterized in that, a control cabin (2) is provided on the framework, and the control portion is arranged in said control cabin to control the scan portion, the driving mechanism and the travelling direction thereof.

9. The detection apparatus according to claim 8, characterized in that, said scan portion includes a liftable vertical strut, a transverse connecting rod on the vertical struct extending as a horizontal cantilever provided with detectors, and the horizontal cantilever is provided on the other end thereof with a hydraulically stretching cylinder, wherein the hydraulically stretching cylinder connects the vertical cantilever and the horizontal cantilever provided with detectors and have the vertical cantilever being perpendicular to the horizontal cantilever or parallel with the horizontal cantilever, said scan portion further includes an electronic linear accelerator, the X-rays thereof always facing the vertical cantilever and the horizontal cantilever after they are perpendicular to each other, and a collimator acting as X-rays shielding is provided between the electronic linear accelerator and the vertical cantilever.

11. A method of inspecting containers, medium and small automobiles, passenger cars, and unit load devices comprising scanning the container, medium and small automobile, passenger car, or unit load device using the detection apparatus of claim 1.
