As shown in fig. 2, the vehicle carrying board P loop transportation system for the vehicle security inspection device D comprises a conveying device 3, a back conveying device 4 (shown in fig. 4a and 4 b), a first switching device 1, and a second switching device 2. The conveyor 3 is arranged at the security check device D, extends from an entrance of the security check device D to an exit of the security check device D via an inspection lane of the security check device D, and the conveyor 3 is configured to convey the tape carrier boards P from the entrance of the security check device D to the exit of the security check device D via the inspection lane of the security check device D. The return device 4 is arranged between the entrance and the exit of the security inspection apparatus D, and the return device 4 is configured to return the empty vehicle boards P from the exit of the security inspection apparatus D to the entrance of the security inspection apparatus D. The first switching device 1 is arranged at an entrance parking space of the security inspection apparatus D, and the first switching device 1 is configured to be switchable between a first position in which it is turned on with the conveying device 3 and a second position in which it is turned on with the back feeding device 4. And, the second switching means 2 is arranged at the exit parking space of the security check device D, and the second switching means 2 is configured to be able to switch between a third position in which it is in communication with the conveying means 3 and a fourth position in which it is in communication with the back feeding means 4.

In some embodiments, the conveyor 3 is arranged at an inspection lane conveying position of the security inspection apparatus. The first switching device 1, the conveying device 3 and the second switching device 2 can be arranged in sequence along the conveying direction of the security check equipment D, and the arrangement position of the returning device 4 is not limited as long as the empty vehicle carrying plates can be returned from the exit parking spaces to the entrance parking spaces of the security check equipment without interfering with the vehicle security check conveying line with the empty vehicle carrying plates.
In some embodiments, the conveying device and the loopback device may have the same construction. For example, each of the conveying device and the returning device may be a roller table constituted by a plurality of conveying rollers, and the plurality of conveying rollers may be rotated in forward and reverse directions along the conveying direction of the security check apparatus D. More specifically, the conveyor may further comprise a conveyor at the entrance of the inspection tunnel and a conveyor at the exit of the inspection tunnel, leaving a gap therebetween for the passage of the inspection radiation. Likewise, the returning device may further comprise a returning device at the entrance of the inspection channel and a returning device at the exit of the inspection channel, with a gap for passage of the inspection radiation. In some embodiments, the first switching device and the second switching device may have the same configuration. For example, each of the first switching device and the second switching device may include a roller table constituted by a plurality of conveying rollers and a lift lever for ascending and descending the plurality of conveying rollers, and the plurality of conveying rollers may rotate in the forward and reverse directions.
According to an exemplary embodiment of the present disclosure, as shown in fig. 3, the conveying device 3 and the back-feeding device 4 adopt a top-bottom double-layer layout, in which the conveying device 3 is located at an upper layer of the double-layer layout and the back-feeding device 4 is located at a lower layer of the double-layer layout. Because the conveying device 3 is used for only conveying the belt loading vehicle carrying plate P1 and the returning device 4 is used for only conveying the no-load loading vehicle carrying plate, the physical space occupied by the conveying roller way can be saved in a better mode by adopting an upper-layer layout and a lower-layer layout.
According to an exemplary embodiment of the present disclosure, the first switching device 1 and the second switching device 2 may both be a lifting roller bed, and the first switching device 1 and the second switching device 2 have the same structure. In the case where the first switching device 1 is switched to the first position, the first switching device 1 is raised to be at the same level as the conveyor 3 located at the upper level; in the case where the first switching device 1 is switched to the second position, the first switching device 1 descends to be at the same level as the loopback device 4 located at the lower level. Likewise, in the case where the second switching device 2 is switched to the third position, the second switching device 2 is raised to be at the same level as the conveyor 3 located on the upper layer; in the case where the second switching device 2 is switched to the fourth position, the second switching device 2 descends to be at the same level as the loopback device 4 located at the lower level. Further, according to the present exemplary embodiment, on the basis that the first switching device 1, the conveying device 3, and the second switching device 2 are arranged in order in the conveying direction of the security check equipment D, the first switching device 1, the loopback device 4, and the second switching device 2 may also be arranged in order in the conveying direction of the security check equipment. Further, according to the present exemplary embodiment, the switching of the first switching device 1 between the first position and the second position and the switching of the second switching device 2 between the third position and the fourth position are both achieved by a lifter (as shown in fig. 4a and 4 b).
Fig. 4a and 4b show the working cooperation between the first and second switching means 1, 2 and the conveyor 3 and the return conveyor 4 in this exemplary embodiment, wherein fig. 4a shows a first state in which the second switching means 2 is level with the conveyor 3 (i.e. the second switching means 2 is in the third position), and fig. 4b shows a second state in which the second switching means 2 is level with the return conveyor 4 (i.e. the second switching means 2 is in the fourth position). As shown in fig. 4a, the second switching device 2 is switched to the third position by the ascending of the lifting lever 21, and is connected to the conveying device 3, and at this time, the belt loading pallet P1 (i.e., the loading pallet on which the test vehicle D is loaded) is conveyed from the conveying device 3 to the second switching device 2. When the vehicle D is taken away, the loaded vehicle carrying board P1 becomes the unloaded vehicle carrying board P2 (i.e., the vehicle carrying board without the vehicle D), and at this time, as shown in fig. 4b, the second switching device 2 is switched to the fourth position by the descending of the lifting rod 21, so that it is connected to the returning device 4, and at this time, the unloaded vehicle carrying board P2 is transferred from the second switching device 2 to the returning device 4.
It should be noted that, although only the working cooperation relationship between the second switching device 2 and the conveying device 3 and the loopback device 4 is described in the foregoing with reference to the exemplary embodiment shown in fig. 4a and 4b, since the first switching device 1 and the second switching device 2 have the same structure and the same working manner, the working cooperation relationship between the first switching device 1 and the conveying device 3 and the loopback device 4 is not repeated.
According to an exemplary embodiment of the present disclosure, the detector of the security inspection apparatus D may be disposed between the conveyor 3 located at the upper layer and the loop back device 4 located at the lower layer. Therefore, the empty loading vehicle plate P2 can not shield the detector when being transported back, and then the interference to the image of the detected vehicle is avoided.
A vehicle carrier loop transport method for a vehicle security inspection apparatus according to an exemplary embodiment of the present disclosure is described next with reference to fig. 5 and 6.
