[0031] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0032] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a category, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally represents a "or" relationship between the front and rear associated objects.

[0033] The security CT device provided by the embodiments of the present application will be described in detail below in combination with the drawings and specific embodiments and application scenarios.

[0034] As shown in Figures 1 to 12 In the embodiments of the present application, a security CT device is disclosed, which comprises a mounting assembly 700, a detection assembly, an intermediate transmission mechanism 300, a left transmission mechanism 100, and a right transmission mechanism 200.

[0035] Specifically, the detection assembly is arranged in the mounting assembly 700 and is configured to detect the object 600, and at least part of the intermediate transmission mechanism 300 passes through the mounting assembly 700.

[0036] The left transmission mechanism 100, the intermediate transmission mechanism 300, and the right transmission mechanism 200 are sequentially arranged along a transmission direction of the object 600, for example, a direction indicated by an arrow L. Figure 3 The intermediate transmission mechanism 300 is detachably connected with the left transmission mechanism 100 and the right transmission mechanism 200.

[0037] In the embodiment, the intermediate transmission mechanism 300 is detachably connected with the left transmission mechanism 100 and the right transmission mechanism 200. In this way, when one or two of the left transmission mechanism 100, the intermediate transmission mechanism 300, and the right transmission mechanism 200 need to be removed during replacement of parts of the security CT device, only the corresponding part needs to be removed, without the need to remove the left transmission mechanism 100, the intermediate transmission mechanism 300, and the right transmission mechanism 200 as a whole. In this way, the weight of the removed part is lighter, and the number of parts connected with the removed part is smaller, thereby making the maintenance of the security CT device more convenient.

[0038] In another embodiment, the left transmission mechanism 100 includes a left framework 110 and a left transmission channel 120, and the left transmission channel 120 is supported on the left framework 110 and detachably connected with the left framework 110. The right transmission mechanism 200 includes a right framework 210 and a right transmission channel 220, and the right transmission channel 220 is supported on the right framework 210 and detachably connected with the right framework 210.

[0039] The intermediate transmission mechanism 300 includes an intermediate transmission channel 310, which is in communication with and detachably connected with the left transmission channel 120 and the right transmission channel 220, and passes through the mounting assembly 700.

[0040] In the embodiment, the left framework 110 and the left transmission channel 120 of the left transmission mechanism 100 are detachably connected, and the right framework 210 and the right transmission channel 220 of the right transmission mechanism are detachably connected. In this way, the left framework 110, the left transmission channel 120, the right framework 210, and the right transmission channel 220 can be individually removed as needed, thereby making the maintenance of the security CT device more convenient. The specific implementation of the detachable connection structure is not specifically limited in the embodiment, for example, but is not limited to, a coupling connector that can be used for cooperation connection.

[0041] As a specific embodiment, the left skeleton 110 is connected with the left transmission channel 120 by screws or bolts to achieve detachable connection between the two, and the right skeleton 210 is connected with the right transmission channel 220 by screws or bolts to achieve detachable connection between the two.

[0042] It should be noted that the left transmission channel 120 and the left skeleton 110 can be in one-to-one correspondence or one-to-multiple correspondence, each left transmission channel 120 is detachably connected with a corresponding left skeleton 110, the right transmission channel 220 and the right skeleton 210 can be in one-to-one correspondence or one-to-multiple correspondence, each right transmission channel 220 is detachably connected with a corresponding right skeleton 210, and the left transmission channel 120 and the right transmission channel 220 can be of any number, which is not limited in the embodiment of the application. In addition, when the number of left transmission channels 120, the number of left skeletons 110, the number of right skeletons 210, and the number of right transmission channels 220 are all at least two, each left transmission channel 120, each left skeleton 110, each right skeleton 210, and each right transmission channel 220 are arranged in sequence along the transmission direction of the measured object 600, for example.

[0043] Of course, in other optional embodiments, the left skeleton 110 and the left transmission channel 120 and the right skeleton 210 and the right transmission channel 220 can also be connected by welding, gluing, or other non-detachable methods.

[0044] In another embodiment, the intermediate transmission mechanism 300 further comprises a first intermediate skeleton 320 and a second intermediate skeleton 330, the first intermediate skeleton 320 is supported at the joint of the left transmission channel 120 and the intermediate transmission channel 310 and is detachably connected with at least one of the left transmission channel 120 and the intermediate transmission channel 310, and the second intermediate skeleton 330 is supported at the joint of the right transmission channel 220 and the intermediate transmission channel 310 and is detachably connected with at least one of the right transmission channel 220 and the intermediate transmission channel 310.

[0045] The joints of the left transmission channel 120 and the intermediate transmission channel 310 and the joints of the right transmission channel 220 and the intermediate transmission channel 310 have relatively large stress and are prone to misalignment with each other, so that the first intermediate skeleton 320 supports the joint of the left transmission channel 120 and the intermediate transmission channel 310 to prevent misalignment between the left transmission channel 120 and the intermediate transmission channel 310, and the second intermediate skeleton 330 supports the joint of the right transmission channel 220 and the intermediate transmission channel 310 to prevent misalignment between the right transmission channel 220 and the intermediate transmission channel 310.

[0046] As a specific implementation, the left skeleton 110 and the middle transmission channel 310 are detachably connected with the first middle skeleton 320 by screws or bolts, and the right skeleton 210 and the middle transmission channel 310 are detachably connected with the second middle skeleton 330 by screws or bolts. It should be noted that the detachable connection in the embodiment of the present application can be that the left skeleton 110 and the first middle skeleton are directly detachably connected, or that the two components are detachably connected with other structures, thereby being indirectly detachably connected together.

[0047] Optionally, as shown in Figure 11 The first middle skeleton 320 includes a support frame 321 and a support platform 322, the support frame 321 is arranged below the support platform 322 and connected with the support platform 322. In this way, the support platform 322 has a large contact area with the left transmission channel 120 and the middle transmission channel 310, thereby improving the stability of the left transmission channel 120 and the middle transmission channel 310. In addition, the structure of the second middle skeleton 330 is the same as that of the first middle skeleton 320, thereby improving the stability of the right transmission channel 220.

[0048] It should be noted that the number of the first middle skeleton 320 and the second middle skeleton 330 can be any number, which is not limited in the embodiment of the present application. When the number of the first middle skeleton 320 and the second middle skeleton 330 is at least two, each first middle skeleton 320 and each second middle skeleton 330 are arranged in sequence along the transmission direction of the measured object 600.

[0049] In other optional embodiments, the first middle skeleton 320 and the second middle skeleton 330 can only support the middle transmission channel 310. In this case, the first middle skeleton 320 and the second middle skeleton 330 are arranged below the middle transmission channel 310 as a whole.

[0050] In further embodiments, the left transmission channel 120, the middle transmission channel 310 and the right transmission channel 220 are configured as a shell structure. In the transmission direction, the shell structure has an inlet and an outlet at two ends thereof. The inlet is used for the measured object 600 to enter the inner cavity of the shell structure, and the outlet is used for the measured object 600 to move out of the inner cavity of the shell structure. The bottom end of the left transmission channel 120 and the bottom end of the right transmission channel 220 are open. The shape of the left transmission channel 120 and the shape of the right transmission channel 220 are approximately inverted U-shaped.

[0051] In the embodiment, the bottom end of the left transmission channel 120 and the bottom end of the right transmission channel 220 are both open, so that the bottom end of the left transmission channel 120 and the bottom end of the right transmission channel 220 do not interfere with other structures during the disassembly of the left transmission channel 120 and the right transmission channel 220, thereby making the disassembly of the left transmission channel 120 and the right transmission channel 220 more convenient.

[0052] In the specific use process, when the security CT device is arranged in the manner shown in FIG. 1, after the connection between the left transmission channel 120 and the left framework 110 is released, the left transmission channel 120 can be moved upward, for example, to remove the left transmission channel 120 from the left framework 110. Conversely, the left transmission channel 120 can be moved downward to support the left transmission channel 120 on the left framework 110. Figure 3

[0053] In other alternative embodiments, the bottom end of the left transmission channel 120 and the bottom end of the right transmission channel 220 can also be closed. At this time, the left transmission channel 120 and the right transmission channel 220 are both, for example, cylindrical structures, and the axis of the left transmission channel 120 and the axis of the right transmission channel 220 are both, for example, parallel to the transmission direction of the measured object 600.

[0054] In another embodiment, the bottom end of the middle transmission channel 310 is closed, for example. In this way, the middle transmission channel 310 is a closed structure in the circumferential direction, thereby making the strength of the middle transmission channel 310 better and the ability to resist external force impact stronger. In addition, in this way, the arrangement of the middle transmission channel 310 in the circumferential direction of the measured object 600 is more uniform, so that the middle transmission channel 310 has less interference with the detection result when detecting the measured object 600 along the circumferential direction of the measured object 600, thereby improving the accuracy of the detection.

[0055] It should be noted that in order to adapt to the detection requirements, the material of the middle transmission channel 310 is different from the material of the left transmission channel 120 and the material of the right transmission channel 220, for example, the material of the left transmission channel 120 and the material of the right transmission channel 220 are the same, and the material strength of the middle transmission channel 310 is generally weaker than the material strength of the left transmission channel 120 and the material strength of the right transmission channel 220. Of course, under the condition of ignoring the cost, the middle transmission channel 310, the left transmission channel 120, and the right transmission channel 220 can also be made of the same material.

[0056] In an alternative embodiment, the bottom end of the middle transmission channel 310 can also be open, at this time, the middle transmission channel 310 is generally in the shape of an inverted U.

[0057] ​In another embodiment, the security CT device further comprises a belt conveyor 400, a first transmission shaft 410 of the belt conveyor 400 is detachably arranged on the left frame 110, a second transmission shaft 420 of the belt conveyor 400 is detachably arranged on the right frame 210, and a belt 430 of the belt conveyor 400 passes through the left transmission channel 120, the middle transmission channel 310 and the right transmission channel 220 in sequence in the transmission direction and is used to drive the measured object 600 to move in the transmission direction.

[0058] In the embodiment, the first transmission shaft 410 can be removed from the left frame 110, and the second transmission shaft 420 can be removed from the right frame 210. In this way, the belt 430 can be directly sleeved on the first transmission shaft 410 and the second transmission shaft 420, so that the belt 430 can be directly selected as an integrated belt. The belt 430 in this form does not need to be processed on site, so that the precision of the belt 430 is higher, and the risk of deviation of the belt 430 in the specific use process is lower. Moreover, the belt in this form does not have a splicing position, so that when the measured object 600 is pressed on the splicing position, the splicing position does not affect the judgment of the security officer, and the security precision is higher. Furthermore, in the embodiment, the first transmission shaft 410 of the belt conveyor 400 is arranged on the left frame 110, and the second transmission shaft 420 is arranged on the right frame 210. In this way, no other frame needs to be additionally arranged to install the first transmission shaft 410 and the second transmission shaft 420, so that the overall structure of the security CT device is relatively simple.

[0059] In the specific use process, when the belt 430 needs to be replaced, first, the first transmission shaft 410 is removed from the left frame 110, and the second transmission shaft 420 is removed from the right frame 210. Then, the original belt 430 is removed from the first transmission shaft 410 and the second transmission shaft 420. Next, the new belt 430 is sleeved on the first transmission shaft 410 and the second transmission shaft 420. Finally, the first transmission shaft 410 is reinstalled on the left frame 110, and the second transmission shaft 420 is reinstalled on the right frame 210, so that the replacement of the belt 430 is completed.

[0060] In other optional embodiments, the first transmission shaft 410 can be connected to the left frame 110 by means of adhesion, welding or other non-detachable connection, and the second transmission shaft 420 can be connected to the right frame 210 by means of adhesion, welding or other non-detachable connection. At this time, the two ends of the strip-shaped belt need to be fused together by means of on-site fusion, so that the new belt is sleeved on the first transmission shaft 410 and the second transmission shaft 420, or a zipper type belt needs to be selected, and the zipper position of the zipper type belt is connected or disconnected, so that the new belt is installed on the first transmission shaft 410 and the second transmission shaft 420, or the original belt is removed from the first transmission shaft 410 and the second transmission shaft 420.

[0061] In an alternative embodiment, the first transmission shaft 410 is a driven shaft for example, and the second transmission shaft 420 is a driving shaft for example, and referring to Figure 9 and Figure 10 As shown, the driving roller 470 is rotatably sleeved on the second transmission shaft 420, and the driven roller 460 is rotatably sleeved on the first transmission shaft 410. In actual use, the driving roller 470 rotates to drive the belt 430 to move, and the belt 430 drives the driven roller 460 to rotate. At the same time, the belt 430 moves, and the measured object 600 moves synchronously with the belt 430 under the action of friction, so as to realize the movement of the measured object 600 along the transmission direction.

[0062] Of course, in other alternative embodiments, the first transmission shaft 410 can also be a driving shaft, and correspondingly, the second transmission shaft 420 is a driven shaft for example. In this case, the driving roller 470 is rotatably sleeved on the first transmission shaft 410, and correspondingly, the driven roller 460 is rotatably sleeved on the second transmission shaft 420.

[0063] In an alternative embodiment, referring to Figure 3 As shown, the belt conveyor 400 further comprises a first tensioning wheel 450, and the belt 430 passes through the first tensioning wheel 450 to realize self-tensioning.

[0064] In an alternative embodiment, at least part of the left framework 110 and at least part of the right framework 210 are made of C-shaped steel or L-shaped steel for example. The C-shaped steel or L-shaped steel has good overall strength and rigidity, and has small mass. In this way, the weight of the left framework 110 and the right framework 210 is relatively light, so that the movement of the left framework 110 and the right framework 210 is relatively convenient.

[0065] Further, referring to Figure 9 As shown, the left framework 110 comprises a first cross beam 111, a first longitudinal beam 112, a first mounting beam 113, a first intermediate beam 115, a third cross beam 116, and a first longitudinal rib 114. The first cross beam 111, the first longitudinal beam 112, and the third cross beam 116 are perpendicular to each other, and the number of the first cross beam 111, the first longitudinal beam 112, and the third cross beam 116 is multiple for example. The multiple first cross beams 111, the first longitudinal beams 112, and the third cross beams 116 are connected to each other to form a cuboid frame structure. The first mounting beam 113 and the first intermediate beam 115 are both connected between two adjacent first longitudinal beams 112, and are oppositely arranged in the height direction of the left framework 110. The first mounting beam 113 is connected to the first intermediate beam 115 through the first longitudinal rib 114.

[0066] Referring to Figure 10As shown, the right framework 210 comprises, for example, a second cross beam 211, a second longitudinal beam 212, a second mounting beam 213, a second intermediate beam 215, a fourth cross beam 216, and a second longitudinal rib 214, the second cross beam 211, the second longitudinal beam 212, and the fourth cross beam 216 are perpendicular to each other, the number of the second cross beam 211, the second longitudinal beam 212, and the fourth cross beam 216 is, for example, multiple, the multiple second cross beam 211, the second longitudinal beam 212, and the fourth cross beam 216 are connected to form a cuboid frame structure, the second mounting beam 213 and the second intermediate beam 215 are both connected between two adjacent second longitudinal beams 212, and are oppositely arranged in the height direction of the right framework 210, and the second mounting beam 213 is connected to the second intermediate beam 215 through the second longitudinal rib 214.

[0067] The first transmission shaft 410 is arranged between two adjacent first longitudinal beams 112, the second transmission shaft 420 is arranged between two adjacent second longitudinal beams 212, and the two ends of the first transmission shaft 410 are connected to the two first longitudinal beams 112 corresponding thereto, and the two ends of the second transmission shaft 420 are connected to the two second longitudinal beams 212 corresponding thereto.

[0068] The first cross beam 111, the second cross beam 211, the third cross beam 116, the fourth cross beam 216, the first longitudinal beam 112, and the second longitudinal beam 212 are, for example, all made of square steel tubes, the first mounting beam 113 and the second mounting beam 213 are, for example, both made of C-shaped steel or L-shaped steel, and the first cross beam 111, the second cross beam 211, the first mounting beam 113, the second mounting beam 213, the first intermediate beam 115, the second intermediate beam 215, the third cross beam 116, and the fourth cross beam 216 are, for example, all arranged in the horizontal direction, and the first longitudinal beam 112, the second longitudinal beam 212, the first longitudinal rib 114, and the second longitudinal rib 214 are, for example, all arranged in the vertical direction.

[0069] In another embodiment, the left transmission mechanism 100 further comprises at least two first support plates 130, and the right transmission mechanism 200 further comprises at least two second support plates 230, each first support plate 130 and each second support plate 230 are sequentially arranged in the transmission direction, each first support plate 130 is movably supported on the left framework 110, each second support plate 230 is movably supported on the right framework 210, and the belt 430 of the belt conveyor 400 passes around the first support plate 130 and the second support plate 230. Optionally, the first support plate 130 is, for example, supported on the first mounting beam 113 in the foregoing, and the second support plate 230 is, for example, supported on the second mounting beam 213 in the foregoing.

[0070] In this embodiment, when the object under test 600 passes the position of the first support plate 130, the object under test 600 can be supported on the first support plate 130. When the object under test 600 passes the position of the second support plate 230, the object under test 600 can be supported on the second support plate 230. In this way, both the first support plate 130 and the second support plate 230 can assist in supporting the object under test 600, thereby making the transmission of the object under test 600 more stable. In addition, in this embodiment, at least two first support plates 130 and at least two second support plates 230 are evenly arranged. Thus, when it is necessary to remove the first support plate 130, the user can remove one or more of the first support plates 130 as needed, instead of having to remove all of the first support plates 130 whenever it is necessary to remove the first support plate 130. At the same time, the user can remove only part of the second support plate 230 according to actual needs, thereby making the use of the security inspection CT equipment more convenient. Furthermore, with this configuration, when one of the first support plates 130 or the second support plate 230 is damaged, only the damaged first support plate 130 or the second support plate 230 needs to be replaced, instead of replacing all the first support plates 130 or all the second support plates 230, thereby saving costs and reducing waste.

[0071] In other alternative embodiments, the left transmission mechanism 100 may not include the first support plate 130, and the right transmission mechanism 200 may not include the second support plate 230. Alternatively, the left transmission mechanism 100 may include an integral first plate and a second plate, with the first plate movably supported on the top of the left frame 110. The left transmission channel 120 and the first plate are disposed opposite to each other in the height direction of the left frame 110. The second plate is movably supported on the top of the right frame 210, with the right transmission channel 220 and the second plate being disposed opposite to each other in the height direction of the right frame 210. The belt 430 of the belt conveyor 400 passes around the first plate and the second plate.

[0072] In another embodiment, the intermediate transmission mechanism 300 further includes a third support plate, which is detachably disposed in the intermediate transmission channel 310. The first segment and the second segment 431 of the belt 430 both pass through the intermediate transmission channel 310, and are arranged opposite to each other in the height direction of the intermediate transmission channel 310, for example, in the height direction of... Figure 3 As indicated by the middle arrow M, the third support plate is located between the first and second sub-segments 431. With this configuration, when the object under test 600 passes the position of the third support plate, the object under test 600 can be supported on the third support plate, thus making the transmission of the object under test 600 more stable.

[0073] In practical use, when it is necessary to replace belt 430, for example, if belt 430 needs to be removed from bottom to top, the replacement steps include, for example, the following:

[0074] S110, removing the first transmission shaft 410 from the left frame 110 and removing the second transmission shaft 420 from the right frame 210;

[0075] S120, removing the first support plate 130, the second support plate 230 and the third support plate;

[0076] S130, removing the original belt 430 from the first transmission shaft 410 and the second transmission shaft 420;

[0077] S140, reassembling the new belt 430 to the second transmission shaft 420 and the first transmission shaft 410;

[0078] S150, reassembling the first support plate 130, the second support plate 230 and the third support plate to the frame;

[0079] S160, reassembling the first transmission shaft 410 to the left frame 110 and reassembling the second transmission shaft 420 to the right frame 210, thus completing the belt 430 replacement.

[0080] As a specific embodiment, the intermediate transmission channel 310 is provided with a support step, the third support plate is supported on the support step, and the third support plate can be moved in and out of the intermediate transmission channel 310 from the first end and the second end of the intermediate transmission channel 310, the first end and the second end being two ends opposite in the direction of the axis of the intermediate transmission channel 310.

[0081] Of course, in other alternative embodiments, the intermediate transmission mechanism 300 can also not include the third support plate.

[0083] In the embodiment, when the first transmission shaft 410 moves towards the direction close to the second transmission shaft 420 or the second transmission shaft 420 moves towards the direction close to the first transmission shaft 410, the distance between the first transmission shaft 410 and the second transmission shaft 420 is reduced, when the first transmission shaft 410 moves towards the direction away from the second transmission shaft 420 or the second transmission shaft 420 moves towards the direction away from the first transmission shaft 410, the distance between the first transmission shaft 410 and the second transmission shaft 420 is increased, with the change of the distance between the first transmission shaft 410 and the second transmission shaft 420, the tension of the belt 430 changes, and the greater the distance, the tighter the belt 430. As can be seen, the scheme adopted in the embodiment can adjust the tension of the belt 430 according to actual needs, so that the belt conveyor 400 can be ensured to operate relatively stably under different working conditions. In addition, the driving shaft of the belt conveyor 400 is usually connected with a cable, in the embodiment, the scheme of moving the driven shaft to adjust the distance between the first transmission shaft 410 and the second transmission shaft 420 can keep the driving shaft of the belt conveyor 400 stationary, so as to prevent the cable from winding and prolong the service life of the cable.

[0084] As a specific implementation, the first adjusting seat 510 and the threaded connecting piece 520 are arranged on the left frame 110, the end of the first transmission shaft 410 is movably arranged in the groove 511 of the first adjusting seat 510, the right frame 210 is provided with a second adjusting seat 530, the second adjusting seat 530 is provided with a clamping groove, the end of the second transmission shaft 420 is clamped in the clamping groove, and the opening of the clamping groove is blocked by a blocking plate 540 to prevent the second transmission shaft 420 from being pulled out of the opening of the clamping groove.

[0085] In other optional embodiments, when the first transmission shaft 410 is a driven shaft, the end of the first transmission shaft 410 can also be directly embedded in the groove 511, in this case, the first transmission shaft 410 cannot move relative to the first adjusting seat 510, and similarly, when the second transmission shaft 420 is a driven shaft, the end of the second transmission shaft 420 can be directly embedded in the groove 511, at this time, the second transmission shaft 420 cannot move relative to the first adjusting seat 510.

[0086] In an optional embodiment, the left frame 110 and the right frame 210 can also be provided with the first adjusting seat 510 and the threaded connecting piece 520, in this case, the first transmission shaft 410 can be driven to move towards the direction close to or away from the second transmission shaft 420 by means of the threaded connecting piece 520, and at the same time, the second transmission shaft 420 can be driven to move towards the direction close to or away from the second transmission shaft 420 by means of the threaded connecting piece 520.

[0087] In a further embodiment, when the first transmission shaft 410 is a driven shaft, the end of the first transmission shaft 410 is in a limiting fit with the inner wall of the groove 511 in the circumferential direction of the first transmission shaft 410, and the moving direction of the first transmission shaft 410 is parallel to the conveying direction; and when the second transmission shaft 420 is a driven shaft, the end of the second transmission shaft 420 is in a limiting fit with the inner wall of the groove 511 in the circumferential direction of the second transmission shaft 420, and the moving direction of the second transmission shaft 420 is parallel to the conveying direction. In this way, the first transmission shaft 410 or the second transmission shaft 420 can be prevented from rotating around its own axis, so that the connection between the first adjusting seat 510 and the first transmission shaft 410 or the second transmission shaft 420 is more reliable.

[0088] In an alternative embodiment, when the first transmission shaft 410 is a driven shaft, the inner wall of the groove 511 can also not be in a limiting fit with the end of the first transmission shaft 410 in the circumferential direction of the first transmission shaft 410, and similarly, when the second transmission shaft 420 is a driven shaft, the inner wall of the groove 511 can also not be in a limiting fit with the end of the second transmission shaft 420 in the circumferential direction of the second transmission shaft 420.

In addition, in a specific detection process, the annular rotating frame 720 rotates, and the measured object 600 can move along the conveying direction at the same time, so that the detection assembly can detect the measured object 600 in more directions, so that the detection accuracy of the measured object 600 is relatively high. In the case where the annular rotating frame 720 rotates and the measured object 600 moves along the conveying direction, the detection path of the detection assembly is, for example, spiral.

[0093] Of course, in other alternative embodiments, the installation assembly 700 can also be in other forms, for example, the installation assembly 700 can include a fixed support connected with the base 990, and the detection assembly is directly fixed on the fixed support.

[0094] Optionally, referring to Figure 1 As shown, the fixed frame 710 is for example a gantry, specifically, it is for example in the form of an inverted U-shaped structure. The annular rotating frame 720 is rotatably arranged on the fixed frame 710 for example through a bearing 940, and one side of the annular rotating frame 720 is arranged on a slip ring 950 for example.

[0095] Optionally, referring to Figure 3 As shown, the annular rotating frame 720 is rotatably arranged on the fixed frame 710 for example through a bearing 940. The bearing 940 can reduce the friction between the annular rotating frame 720 and the fixed frame 710, so that the rotation of the annular rotating frame 720 is more stable.

[0096] In specific use, the right transmission mechanism 200 can be removed for example, so as to realize the replacement of the bearing 940.

The ray source 810 is configured to emit X-rays, and the detector 820 is configured to receive the X-rays that have passed through the object 600. The X-rays do not cause damage to the object 600, thereby preventing the object 600 from being damaged due to radiation, and the X-rays have strong penetrating power, thereby making the detection accuracy of the security CT device higher.

[0102] In particular, in use, the ray source 810 emits X-rays toward the object 600, the detector 820 receives the X-rays that have passed through the object 600 and converts them into digital signals, and finally, a CT image is obtained by processing the digital signals. More specifically, by using the interaction between X-rays and matter, the detection assembly can detect the composition of the object 600, and then restore the three-dimensional shape of the object 600 through an algorithm, and distinguish the specific material of the object 600 through calculation, and determine whether there is dangerous contraband, etc.

[0103] In another embodiment, referring to Figure 4 As shown, the security CT device further includes a cooling device 830 arranged on the annular rotating frame 720. The ray source 810 is internally provided with a cooling oil passage.

In this way, when the temperature of the ray source 810 is high, the cooling device 830 can be used to cool the ray source 810, thereby preventing the ray source 810 from being damaged due to high temperature.

In this way, during specific processing, it is not necessary to process the entire bottom end surface of the left framework 110, the right framework 210, the first intermediate framework 320 and the second intermediate framework 330 to be attached to the base 990, but only the leveling plate 910 needs to be connected to the left framework 110, the right framework 210, the first intermediate framework 320 and the second intermediate framework 330, and the surface of the leveling plate 910 facing the base 990 is processed to be attached to the base 990. In this way, the area to be processed is smaller, thereby making the processing of the security CT device more convenient.

[0108] In other optional embodiments, the installation device can also not include the leveling plate 910, at which time, for example, the entire bottom end surface of the left framework 110, the right framework 210, the first intermediate framework 320 and the second intermediate framework 330 can be machined to ensure that the entire bottom end surface of the left framework 110, the right framework 210, the first intermediate framework 320 and the second intermediate framework 330 can be attached to the base 990.

In this way, when it is necessary to adjust the position of the security CT device, the adjusting screw 920 is rotated to separate the support seat 921 from the support surface, so that the security CT device can be moved flexibly. On the contrary, when it is necessary to keep the security CT device at a desired position, the adjusting screw 920 is rotated to make the support seat 921 contact with the support surface and make the roller 930 separate from the support surface, so that the security CT device can be kept at the desired position more stably.
