Referring to fig. 1 and 2 together, an embodiment of the present invention provides an online security inspection system, including a conveying assembly S, the conveying assembly S including a base B having a predetermined length and a conveyor belt a disposed on the base B, wherein the online security inspection system further includes: a guide assembly 10, a gantry 1, a radiation source arrangement 2 and a detector arrangement 3.
the conveying assembly S can be equipment for conveying articles commonly used in the industries of civil aviation, rail transit, customs, logistics, food, coal and the like, wherein the base B comprises a support and a dragging plate arranged on the support, and the conveyor belt A runs around the dragging plate to convey the articles.
The guiding assembly 10 is disposed between the base B and the conveyor a to elevate the support surface of the conveyor a and establish a detection surface.
the frame 1 is disposed at the outer periphery of the conveying module S and covers the guide module 10.
The radiation source arrangement 2 is arranged at either one of the guiding assembly 10 or the gantry 1, the radiation source arrangement 2 generally comprising a radiation source and a collimating arrangement.
The detector arrangement 3 may be a portal frame structure or an L-frame structure. Taking an L-shaped frame structure as an example, the detector device 3 includes a horizontal detector 31 and a vertical detector 32, the horizontal detector 31 is disposed on the other one of the guiding assembly 10 and the rack 1, the vertical detector 32 is disposed on a side portion of the guiding assembly 10, a first detection beam surface is formed between the detector device 3 and the radiation source device 2, and the guiding assembly 10 is used for guiding the object O to be detected to pass through the first detection beam surface along the conveyor belt a.
The detection rays emitted by the ray source device 2 are distributed in a fan shape on the first detection beam surface, and can provide detection rays with a scanning range of at least 70 degrees to 120 degrees. The conveyor belt a is used as a detection reference surface of the object O, and drives the object O to be detected to gradually lift and move to the upper side of the bearing member 11 along the inclined surface 120 of the guide member 12, and to pass through the first detection beam surface at a constant speed, so as to form image information of the object O to be detected.
When the guide assembly 10 is arranged between the base B and the conveyor belt A, firstly, the conveyor belt A of the original conveying assembly S is loosened through the tensioning mechanism, the guide assembly 10 is placed on a carriage of the base B and fixed, for example, in a screw fastening mode, the guide assembly 10 is convenient to detach, the guide assembly 10 can also be welded or riveted on the carriage, and then the conveyor belt A is tensioned again and adjusted to prevent deviation.
the pallet of the base B is supported in the vertical direction without being mechanically connected to the conveyor belt a or the guide assembly 10. From this, whole transformation and installation are simple, need not set up recess etc. on base B's layer board or frame, and the transformation work volume is less, can not destroy base B's original structure, has reduced the risk of damaging original conveying component.
According to the online security inspection system provided by the invention, the guide assembly 10 is arranged between the base B of the original conveying assembly S and the conveyor belt A so as to heighten the supporting surface of the conveyor belt A, and the radiation source device 2 and the detector device 3 are arranged on the guide assembly 10 and the rack 1 covering the periphery of the guide assembly, so that the base B is not required to be grooved, the deployment and reconstruction cost of the online security inspection system is reduced, and the construction convenience is improved.

Because the occupied space of the transverse detector 31 is small, the supporting surface of the conveyor belt A only needs to be higher by a small size, namely the height of the bearing member 11 in the vertical direction is small, so that the whole volume of the online security inspection system is small.
In some embodiments, the radiation source device 2 is disposed below the carrier 11 corresponding to the recess 110, the transverse detector 31 is disposed on the gantry 1, and the vertical detector 32 is disposed at a side of the carrier 11, such that a first detection beam plane is formed between the detector device 3 and the radiation source device 2.
the guide member 12 is connected to at least one end of the bearing member 11 in the length direction thereof, the guide member 12 has an inclined surface 120 tapered from the end connected to the bearing member 11 to the end distant from the bearing member 11 in the thickness direction thereof, and the upper surface 11a and the inclined surface 120 form a support surface of the conveyor belt a. The guide member 12 has an inclination angle θ, which is wedge-shaped as a whole, and is determined according to the height of the carrier member 11 and the technical parameters of the conveyor belt a.

The flexible board 112 is typically a carbon fiber board with a small thickness, but other flexible materials, such as Polyvinyl Chloride (PVC) polymer film, may be used instead. For the conditions of higher bearing surface quality requirement and better flatness, rigid materials which can penetrate through rays, such as metal films and the like, can also be directly adopted.

Specifically, one side of either one of the guide member 12 and the carrier member 11 toward the other is provided with a fixed shaft extending in the width direction, on which the roller 13 is provided, and the outer surface of the roller 13 is disposed in alignment with the upper surface 11a of the carrier member 11. The rolling member 13 may be a roller shaft or a plurality of rollers so as to generate sliding friction with the conveyor belt a, and the rolling member 13 may convert the sliding friction into rolling friction, thereby reducing the wear of the conveyor belt a and prolonging the service life of the conveyor belt a. When the rolling member 13 is a roller, a protective cover 131 is provided at an end thereof to prevent a gap from being generated between the edge of the conveyor belt a and the guide member, prevent foreign materials from entering the gap to damage the conveyor belt a, prevent a person from being injured by the nip, and prevent the object from being damaged by the nip.
