Detailed Description

As shown in fig. 1-4, a channel-type X-ray security inspection system can use the principle of X-ray fluoroscopy to image a human body to inspect metal or non-metal contraband hidden by people. The utility model discloses a ray source 5, detecting plate 6, detecting arm 4 is head and the tail enclosed construction, and such structural strength is higher. The detection arm 4 is of a quadrilateral structure, guide assemblies, namely guide rods 7, which are vertical in the axial direction are arranged at a pair of diagonal positions, and the guide rods 7 guide the lifting motion of the detection arm 4. In order to balance the force on the feeler arm 4 as much as possible, the guide rods 7 are arranged diagonally to the feeler arm 4. The elevation of the detecting arm 4 is driven by the screw 8. In order to also try to balance the force on the feeler arm 4, the spindles 8 are provided in two groups and are each arranged in another pair of diagonal positions.

In order to make the two groups of screw rods 8 synchronously rotate so as to make the detection arm 4 stably lift, the lower ends of the two groups of screw rods 8 are rigidly fixed with transmission belt wheels 10, and a transmission synchronous belt 11 is connected between the two groups of transmission belt wheels 10. A driving belt wheel 9 is rigidly connected below one (any) of the two groups of screw rods 8. The drive pulley 9 is connected to a drive pulley 13 via a drive timing belt 12. The driving pulley 13 is mounted on the output shaft of the driving motor 14 and rigidly connected thereto. Therefore, the power output by the driving motor 14 can drive the two sets of screw rods 8 to synchronously rotate through the driving synchronous belt 12 and the transmission synchronous belt 11.

The base 16 right below the probe arm 4 is provided with a groove 20 capable of accommodating the probe arm 4, and the depth H of the groove 20 is greater than or equal to the thickness of the probe arm 4. When the probe arm 4 is in the groove 20, the upper surface of the probe arm is flush with the upper surface of the base 16, so that the passage of a person to be detected is facilitated. In order to prevent the ray from leaking outside when the equipment works, the left and right side wall plates 3 of the channel can be made of lead glass or a material containing a lead plate, the utility model discloses well adopt aluminium glass. For same reason, passageway entry and exit are provided with respectively and enter door 1 and export door 2, and enter door 1 and export door 2 comprise leaded glass or by the material that includes the stereotype, the utility model discloses well adoption aluminium glass.

The inner area of the probe arm 4 close to the probe plate 6 is provided with a safety grating 19, which is used for preventing the probe arm 4 from colliding with the person to be detected when the probe arm is lifted. The upper surface of the base 16 at the entrance of the passageway has a footprint pattern 17 for indicating the standing position of the person to be inspected.

The utility model discloses a concrete working method does: in the initial state, the probe arm 4 is in the groove 20 and its upper surface is flush with the upper surface of the base, the entrance door 1 is in the open state, and the exit door 2 is in the closed and locked state. The person to be inspected enters the passageway from the entrance of the passageway and stands on the footprint pattern 17 according to the prompt. The access door 1 is then closed and the safety light barrier 19 opens to check whether a person is in the plane of the light beam. When the person is not in the beam plane, the detector arm 4 starts to rise uniformly while the radiation source 5 is switched on. During this process, the radiation beam is scanned over the body of the examined person, while the transmitted radiation is received by the detection plate 6. After processing, the transmitted ray signal is converted into a perspective image of the detected person and transmitted to a computer of an operator. The feeler arm 4 is lowered immediately after rising to the top and returns to the initial position. The operator judges whether the person to be detected has prohibited articles hidden therein according to the perspective image, and determines whether to open the exit door 2 to allow or refuse the person to be detected to pass through.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention should be included in the scope of the present invention.
