Embodiment 1
[0026] refer to Figure 1 to Figure 7 , the ultra-low-dose X-ray human body security inspection system with double exchange platforms of the present invention includes an X-ray source 10, a collimation component 20, an inspection channel 30, an X-ray detector 40, an image acquisition and processing device 50, a control device 60 and an operation Console 70. Such as figure 1 As shown, the inspection channel 30 includes an entrance 31 , an exit 32 and a mobile inspection platform 33 , the entrance 31 and the exit 32 are respectively located on the front left side and the rear right side of the mobile inspection platform 33 . The X-ray source 10 is installed in the rear center of the mobile inspection platform 33, which generates ultra-low dose X-rays. The front part of the X-ray source is equipped with a collimating part 20, and the collimating part extends from the output end of the X-ray source 10 to the rear side of the mobile inspection platform 33. An X-ray detector 40 i...
Embodiment 2
[0037] The basic structure of this embodiment is the same as that of Embodiment 1, except that the gear transmission between the two upper large gears 3353 and the two lower large gears 3354 of the platform driving mechanism is replaced by a belt transmission mechanism.
[0038] Such as Figure 7 , Figure 8 The platform driving mechanism 335 includes a reduction motor 3351, a driving gear 3352, two upper gears 3353 meshing with the first rack 3312 or the second rack 3322 on the first platform or the second platform respectively, two lower gears 3353, The bull gear 3354 and four pinion gears 3355 meshing with the upper bull gear 3353 and the lower bull gear 3354 respectively are provided with a belt transmission mechanism 3357 between the two upper bull gears 3353 and the two lower bull gears 3354. The mechanism includes a driving pulley 35571, two driven pulleys 35572 and a belt 35573. The driving pulley 35571 is installed on the motor shaft of the reduction motor 3351 on th...
Embodiment 3
[0040] The basic structure of this embodiment is the same as that of Embodiment 1, except that the gear transmission between the two upper large gears 3353 and the two lower large gears 3354 of the platform driving mechanism is replaced by a belt transmission mechanism.
[0041] Such as Figure 9The platform driving mechanism 335 includes a reduction motor 3351, a driving gear 3352, two upper gears 3353 meshing with the first rack 3312 or the second rack 3322 on the first platform or the second platform respectively, two lower gears 3353, The bull gear 3354 and four pinion gears 3355 meshing with the upper bull gear (3353) and the lower bull gear 3354 respectively, are provided with a sprocket transmission mechanism 3358 between the two upper bull gears 3353 and the two lower bull gears 3354, The sprocket transmission mechanism includes a driving sprocket 35581, two driven sprockets 35582 and a chain 35583. The driving sprocket 35581 is mounted on the motor shaft of the reduct...
