A mobile inspection system comprises: a stand; a ray source mounted to the stand and configured to generate a ray; a substantially inverted L-shaped detector beam comprising a horizontal detector beam portion and an upright detector beam portion connected to one end of the horizontal detector beam portion; a plurality of detectors configured to receive the ray emitted from the ray source, the plurality of detectors being disposed to at least one of the horizontal detector beam portion and the upright detector beam portion; and a drive device disposed to the stand, connected with the other end of the horizontal detector beam portion, and configured to drive the detector beam to rotate around an upright axis, wherein the ray source and the detector beam rotate synchronously.

Mobile inspection system

The present invention discloses a gantry configuration for a combined mobile radiation inspection system comprising a first arm frame, a second arm frame and a third arm frame. The first, second and third arm frames define a scanning channel to allow an inspected object to pass therethrough. The gantry configuration for the combined mobile radiation inspection system further comprises a position sensing device configured to detect a position error between the first arm frame and the second arm frame; and a controller configured to control a moving speed of at least one of the first arm frame and the second arm frame based on the detected position error, so that the position error between the first arm frame and the second arm frame is equal to zero. Compared with the prior art, the present invention is advantageous at least in that an automatic deviation correction device is provided on the gantry arm frame, and thus the position error between both side arm frames can be automatically controlled to zero, so that the gantry arm frame can be effectively prevented from being subjected to a force and deforming, and the radiation detector can receive the full ray, thereby improving the imaging quality.

The present invention relates to a trailer system, and particularly to a self-driving trailer system for a radiation imaging inspection system and a method for inspecting a vehicle by radiation imaging of a vehicle through the trailer system. The self-driving trailer system comprises two trailers symmetrical in structure. Each of the trailers comprises a driving device, running wheels, a trailer body, a carrying device, a lift cylinder, a balance wheel, and two pairs of guide wheels. The driving device, the running wheels, and the balance wheel are coupled with the trailer body. The carrying device is coupled with the trailer body through the lift cylinder. A front carrying arm and a rear carrying arm can clamp front wheels of a vehicle under inspection, and move upwards and downwards by the lift cylinder. The trailer system according to the present invention is smooth and reliable in operation and simple in structure, and is applicable to different diameters of wheels of container lorries under inspection and is convenient in operation.
