Description

Technical Field

[0001] The present disclosure relates to the technical field of security inspection, and more particularly, to a loading mechanism for X-ray detection and a security inspection method. Background Art

[0002] CT technology has played an important role in security inspection because it can eliminate the influence of object overlap. CT devices are also widely used in technical fields such as item detection. CT devices can not only detect smaller items such as luggage and airline boxes, but also detect larger items such as containers and vehicles.

[0003] In the related art, a CT device obtains projection data at different angles by rotating an X-ray machine and a detector, and obtains a tomographic image through a reconstruction method, so as to obtain internal information of the detected item. Combining dual-energy or multi-energy imaging technology can reconstruct the atomic number and electron density of the detected substance, so as to realize the identification of the type of substance, and has achieved good results in the detection of explosives, dangerous goods, etc.

[0004] For example, in the related art, in some special application scenarios, due to the particularity of the detected item, the CT device is set in a designated area, and the detected item needs to be delivered to the designated area before the CT scan of the detected item can be performed. In this process, the detected item needs to be loaded onto the loading mechanism, and the loading mechanism drives the detected item to move to the designated area. The support assembly of the existing loading mechanism is used to clamp the detected item. Since the relative position between the detected item and the support assembly needs to be adjusted when the detected item is loaded onto the support assembly, the support assembly will be severely worn after a long time of use. After the support assembly is worn, it will affect the accuracy of the CT scan of the detected item. Therefore, when the support assembly is worn to a certain extent, it needs to be replaced, which wastes manpower and material resources and reduces the efficiency of the CT scan.

[0005] The above information disclosed in this part is only used to understand the background of the disclosure concept of the present disclosure. Therefore, the above information may include information that does not constitute prior art. Summary of the Invention

Detailed implementation manners

[0051] The specific embodiments of the present disclosure will be described in detail below. It should be noted that the embodiments described here are only for illustrative purposes and do not limit the present disclosure. In the following description, in order to provide a thorough understanding of the present disclosure, a large number of specific details are set forth. However, it will be apparent to those of ordinary skill in the art that the present disclosure does not have to employ these specific details. In other instances, well-known structures, materials, or methods have not been specifically described to avoid obscuring the present disclosure.

[0052] Throughout the specification, references to "one embodiment", "an embodiment", "an example", or "an example" mean that a particular feature, structure, or characteristic described in connection with the embodiment or example is included in at least one embodiment of the present disclosure. Thus, the phrases "in one embodiment", "in an embodiment", "an example", or "an example" appearing throughout the specification do not necessarily all refer to the same embodiment or example. Additionally, the specific features, structures, or characteristics may be combined in any suitable combination and / or sub-combination in one or more embodiments or examples. Further, those of ordinary skill in the art should understand that the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0053] The terms used herein are merely for describing specific embodiments and are not intended to limit the present disclosure. The terms "including", "comprising", etc. as used herein indicate the presence of features, steps, operations, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.

[0054] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those of ordinary skill in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0055] In the related art, in some special application scenarios, due to the particularity of the item to be detected, the CT device is set in a designated area, and the item to be detected needs to be delivered to the designated area before the CT scan of the item to be detected can be performed. During this process, the item to be detected needs to be loaded onto the loading mechanism, and the loading mechanism drives the item to be detected to move to the designated area. The support component of the existing loading mechanism is used to clamp the item to be detected. Since the relative position between the item to be detected and the support component needs to be adjusted when the item is loaded onto the support component, the support component will be severely worn after long-term use. After the support component is worn, it will affect the accuracy of the CT scan of the item to be detected. Therefore, when the support component is worn to a certain extent, it needs to be replaced, which wastes manpower and material resources and reduces the efficiency of the CT scan.

[0056] The following refers to Figures 1-6 Describe a loading mechanism 100 for X-ray detection and a method for security inspection according to an embodiment of the present disclosure.

[0057] As Figure 1 shown, the loading mechanism 100 according to an embodiment of the present disclosure includes a frame 10, a clamping member 20 for clamping a workpiece 200, an auxiliary support bracket assembly 30, and a support roller assembly 40.

[0058] Specifically, with reference to Figure 1 , the frame 10 is configured to move between a loading area and a security inspection area; the auxiliary support bracket assembly 30 is provided on the frame 10, and the auxiliary support bracket assembly 30 is configured to be able to be installed and cooperate with the clamping member 20; the support roller assembly 40 is provided on the frame 10, and the support roller assembly 40 is configured to be able to be installed and cooperate with the clamping member 20. Among them, in the loading area, when the clamping member 20 is installed and cooperates with the auxiliary support bracket assembly 30, it is suitable for clamping the workpiece 200 to the clamping member 20. After the clamping member 20 clamps the workpiece 200, it is suitable for moving the clamping member 20 and the workpiece 200 as a whole to the support roller assembly 40. After the clamping member 20 clamps the workpiece 200 and is installed and cooperates with the support roller assembly 40, the frame 10 is suitable for moving to the security inspection area.

[0059] It can be understood that in the field of security inspection, a loading area and a security inspection area are set for the smooth security inspection of items. In the embodiments of the present disclosure, the item to be detected is named the workpiece 200. The loading area is used to store the workpiece 200, and the security inspection area is used to perform security detection on the workpiece 200. Therefore, during security inspection, the loading mechanism 100 needs to load the workpiece 200 in the loading area, transport the workpiece 200 to the security inspection area after loading the workpiece 200, and perform security detection on the workpiece 200.

[0060] The frame 10 is a frame structure, as Figure 2As shown, the frame 10 may include two longitudinal beams 11 and two cross beams 12. A connecting beam is also provided between the two longitudinal beams 11. Multiple connecting beams are arranged at intervals along the length direction of the longitudinal beam 11, and the multiple connecting beams are used to enhance the structural strength of the frame 10. The longitudinal beam 11, the cross beam 12, and the connecting beam can all be made of profiles. As Figure 1 As shown, the auxiliary support bracket assembly 30 is fixedly installed on the top surface of the frame 10 or movably installed on the top surface of the frame 10. The support roller assembly 40 is fixedly installed on the top surface of the frame 10 or movably installed on the top surface of the frame 10.

[0061] When loading the workpiece 200, the loading mechanism 100 stops in the loading area, places the clamping member 20 on the auxiliary support bracket assembly 30, and clamps the workpiece 200 to the clamping member 20. During the process of clamping the workpiece 200, the relative position between the workpiece 200 and the clamping member 20 can be adjusted so that the clamping member 20 stably clamps the workpiece 200 and the clamping position can meet the requirements of precise detection. The auxiliary support bracket assembly 30 is configured to be able to be installed and cooperate with the clamping member 20, which can facilitate the stable placement of the clamping member 20 on the auxiliary support bracket assembly 30, thereby facilitating the clamping of the workpiece 200.

[0062] After the clamping member 20 clamps the workpiece 200, the clamping member 20 and the workpiece 200 as a whole can be transferred to the support roller assembly 40. Here, a crane can be used to hoist the clamping member 20 and the workpiece 200 as a whole to the support roller assembly 40. The support roller assembly 40 is configured to be able to be installed and cooperate with the clamping member 20, which can facilitate the stable placement of the clamping member 20 on the support roller assembly 40. After transferring the clamping member 20 and the workpiece 200 as a whole to the support roller assembly 40, the frame 10 can be started, and the frame 10 drives the workpiece 200 to move to the security inspection area, so that the workpiece 200 can be subjected to security inspection.

[0063] Optionally, walking wheels are provided at the bottom of the frame 10, and the walking wheels walk from the loading area to the security inspection area along the target route to transport the workpiece 200 to the security inspection area. The frame 10 can be connected to a tractor, and the frame 10 is towed from the loading area to the security inspection area by the tractor. A driving member can also be provided on the frame 10, the driving member is drivingly connected to the walking wheels, and the driving member drives the walking wheels to walk along the target route to transport the workpiece 200 to the security inspection area.

[0064] Optionally, slide rails are provided at the bottom of the frame 10, and matching chutes are provided between the loading area and the security inspection area. The slide rails are slidably matched with the chutes. After the clamping member 20 and the workpiece 200 are hoisted as a whole to the support roller assembly 40, the frame 10 slides along the chute to transport the workpiece 200 to the security inspection area.

[0065] During the process of clamping the workpiece 200 by the clamping member 20, by configuring the auxiliary support bracket assembly 30 to be capable of being installed and cooperating with the clamping member 20, it is convenient to stably place the clamping member 20 on the auxiliary support bracket assembly 30, thereby facilitating the clamping of the workpiece 200. During the process of installing the workpiece 200 and the clamping member 20 on the support roller assembly 40, by configuring the support roller assembly 40 to be capable of being installed and cooperating with the clamping member 20, it is convenient to stably place the clamping member 20 on the support roller assembly 40.

[0066] For the loading mechanism 100 according to an embodiment of the present disclosure, by arranging the auxiliary support bracket assembly 30 on the frame 10, the work of loading the workpiece 200 can be completed on the auxiliary support bracket assembly 30, and then the clamping member 20 and the workpiece 200 are integrally transferred to the support roller assembly 40 after loading, which can reduce the wear of the support roller assembly 40. Since the support roller assembly 40 is a support structure for supporting the workpiece 200 for security inspection, reducing the wear of the support roller assembly 40 can ensure the security inspection accuracy of the workpiece 200. Reducing the wear of the support roller assembly 40 can also reduce the replacement frequency of the support roller assembly 40, thereby saving manpower and material resources and improving the security inspection efficiency of the workpiece 200.

[0067] According to some embodiments of the present disclosure, as Figure 1 shown, a first positioning component is provided at the bottom of the frame 10, and a second positioning component is provided in the security inspection area. When the frame 10 moves to the security inspection area, the first positioning component is adapted to cooperate with the second positioning component to position the frame 10. The positioning positions of the first positioning component and the second positioning component can be positions suitable for security inspection. Thus, the loading mechanism 100 can be docked at a position suitable for security inspection, facilitating the smooth progress of the security inspection work and ensuring the accuracy of the security inspection.

[0068] In some embodiments of the present disclosure, as Figure 1 and Figure 2 shown, the first positioning component can be a positioning wheel assembly, the positioning wheel assembly is rollably arranged on the frame 10, the second positioning component can be a positioning track assembly, and a positioning portion is provided on the running surface of the positioning track assembly. When the positioning wheel assembly walks to the positioning portion on the running surface, the positioning wheel assembly is in positioning cooperation with the positioning track assembly.

[0069] The frame 10 has a length direction and a width direction. The length direction is as Figure 1 shown in the D1 direction in Figure 2As shown in the direction of D2. Along the length direction of the frame 10, the opposite ends of the frame 10 are defined as the first end and the second end of the frame 10 respectively. Along the width direction of the frame 10, the opposite sides of the frame 10 are defined as the first side and the second side of the frame 10 respectively. The frame 10 has a first central plane and a second central plane. The direction of the first central plane is consistent with the length direction. The first side and the second side are located on both sides of the first central plane. The direction of the second central plane is consistent with the width direction. The first end and the second end are located on both sides of the second central plane.

[0070] The positioning wheel assembly includes one or more positioning wheels, and the number of positioning wheels is set according to actual needs. For example, the number of positioning wheels is one, and the positioning wheel is located in the central area of the frame 10. The number of positioning wheels is two, and the two positioning wheels are respectively arranged near the first end and the second end of the frame 10, or the two positioning wheels are located in the area near the second central plane, and one positioning wheel is arranged near the first side, and the other positioning wheel is arranged near the second side. The number of positioning wheels is four, two positioning wheels are arranged near the first end of the frame 10, and the other two positioning wheels are arranged near the second end of the frame 10.

[0071] The positioning track assembly includes one or more positioning tracks. The number of positioning tracks matches the number of positioning wheels. The positioning tracks are fixed in the security inspection area. The positioning wheel can travel along the walking surface of the positioning track. A positioning part is arranged on the walking surface of the positioning track, that is, a protrusion protruding from the walking surface is formed at the end of the walking surface. When the positioning wheel travels to the position where the positioning part is located, the positioning wheel abuts against the positioning part, and the positioning part can limit the movement of the positioning wheel along the front-back direction of the security inspection area, so that the frame 10 is docked at a fixed position in the security inspection area.

[0072] It can be understood that through the cooperation of the positioning wheel assembly and the positioning track assembly, it is convenient to realize the cooperation of the first positioning component and the second positioning component to position the frame 10. Since the positioning wheel assembly is rollably arranged on the frame 10, when the positioning wheel assembly is matched with the positioning part, the positioning wheel assembly can roll to the positioning part on the walking surface, which is easy to realize and time-saving and labor-saving.

[0073] According to some embodiments of the present disclosure, such as Figure 1 and Figure 2As shown, the loading mechanism 100 may further include a traveling wheel assembly. The traveling wheel assembly may include a first traveling wheel 53, and the first traveling wheel 53 is rotatably provided at the bottom of the frame 10. The positioning wheel assembly may include a first positioning wheel 51, and the first positioning wheel 51 is rotatably provided at the bottom of the frame 10. The first positioning wheel 51 and the first traveling wheel 53 are spaced apart in the length direction of the frame 10. Taking the ground as a reference, the radially lowest point of the first positioning wheel 51 is higher than the radially lowest point of the first traveling wheel 53. The positioning track assembly at least includes a first track 61. The running surface of the first track 61 has a slope portion and a flat portion. A positioning portion is provided on the flat portion. When the first positioning wheel 51 travels from the slope portion to the flat portion and is in positioning cooperation with the positioning portion, the first traveling wheel 53 contacts or separates from the slope portion.

[0074] Specifically, the top surface of the first track 61 is above the ground. Along the traveling direction of the frame 10, the slope portion is located at the rear end of the first track 61, and the flat portion is located at the front end of the first track 61. The inclination angle of the slope portion is set according to actual requirements. The inclination angle of the slope portion may be 10 degrees, 15 degrees, 20 degrees, etc. The positioning portion is located at one end of the flat portion away from the slope portion.

[0075] Both the first positioning wheel 51 and the first traveling wheel 53 are rotatably mounted at the bottom of the frame 10. Along the vertical direction, the radially lowest point of the first positioning wheel 51 is higher than the radially lowest point of the first traveling wheel 53. Thus, when the first traveling wheel 53 travels along the ground, the first positioning wheel 51 does not contact the ground.

[0076] The number of the first positioning wheels 51 and the first traveling wheels 53 is set according to actual requirements. For example, the number of both the first positioning wheels 51 and the first traveling wheels 53 is one, and the first positioning wheels 51 and the first traveling wheels 53 are mounted in the central area at the bottom of the frame 10. The number of the first tracks 61 is also one.

[0077] The first running wheel 53 runs along the ground, and the first running wheel 53 drives the frame 10 to run from the loading area to the security inspection area. When the frame 10 runs close to the first track 61, the frame 10 is adjusted so that the first positioning wheel 51 and the first running wheel 53 are aligned with the first track 61. The first running wheel 53 runs close to the first track 61, and as the first running wheel 53 continues to roll, the first positioning wheel 51 rolls from the slope portion toward the flat portion, and the slope portion is used to achieve a stable transition when the first positioning wheel 51 runs along the running surface of the first track 61. In the process of the first positioning wheel 51 running along the flat portion, the first positioning wheel 51 gradually approaches the positioning portion of the flat portion. The first positioning wheel 51 moves to conflict with the positioning portion, at which time, the first positioning wheel 51 is positioned and matched with the positioning portion, and the first running wheel 53 stops rolling along the slope portion. When the first positioning wheel 51 is positioned and matched with the positioning portion, the first running wheel 53 may contact the slope portion; the first running wheel 53 may also be in a separated state from the slope portion, that is, the first running wheel 53 does not contact the slope portion.

[0078] It can be understood that the first running wheel 53 can be used to enable the rack 10 to move between the loading area and the security inspection area. When neither the first running wheel 53 nor the first positioning wheel 51 runs on the first track 61, the radial lowest point of the first positioning wheel 51 is higher than the radial lowest point of the first running wheel 53, so that only the first running wheel 53 is in contact with the ground, thereby driving the rack 10 to move, and the first positioning wheel 51 does not need to contact the ground, thereby avoiding wear of the first positioning wheel 51 and reducing the replacement frequency of the first positioning wheel 51.

[0079] It can be understood that the walking surface of the first track 61 has a sloped portion and a flat portion, and a positioning portion is provided on the flat portion. When the first positioning wheel 51 walks on the flat portion, the slope of the slope is constructed so that when the first positioning wheel 51 is positioned and matched with the positioning portion, the first walking wheel 53 contacts or separates from the slope. This can facilitate the simultaneous arrangement of the first walking wheel 53 and the first positioning wheel 51 on the frame 10, and ensure that the first positioning wheel 51 does not interfere with or affect each other when realizing the positioning function and the first walking wheel 53 does not interfere with or affect each other when realizing the function of driving the frame 10 to move.

[0080] According to some embodiments of the present disclosure, the loading mechanism 100 may further include a traveling wheel assembly. The traveling wheel assembly may include a first traveling wheel 53, and the first traveling wheel 53 is rollably disposed at the bottom of the frame 10. The positioning wheel assembly may include a first positioning wheel 51, and the first positioning wheel 51 is rollably disposed at the bottom of the frame 10. The first positioning wheel 51 and the first traveling wheel 53 are spaced apart in the width direction of the frame 10. With the ground as a reference, the radially lowest point of the first positioning wheel 51 is higher than the radially lowest point of the first traveling wheel 53. The positioning track assembly at least includes a first track 61. When the first positioning wheel 51 travels on the first track 61, the first track 61 is spaced apart from the first traveling wheel 53. The first track 61 is provided with a positioning portion, and when the positioning portion is configured to be in positioning cooperation with the first positioning wheel 51, the first traveling wheel 53 contacts or separates from the ground.

[0081] Specifically, the top surface of the first track 61 is above the ground, and a protruding positioning portion is formed at the end of the running surface of the first track 61.

[0082] In the width direction of the frame 10, the first positioning wheel 51 and the first traveling wheel 53 are spaced apart. Both the first positioning wheel 51 and the first traveling wheel 53 are rollably mounted at the bottom of the frame 10. In the vertical direction, the radially lowest point of the first positioning wheel 51 is higher than the radially lowest point of the first traveling wheel 53. Thus, when the first traveling wheel 53 travels along the ground, the first positioning wheel 51 does not contact the ground.

[0083] The number of the first positioning wheels 51 and the first traveling wheels 53 is set according to actual needs. For example, the number of the first positioning wheels 51 is one, the number of the first traveling wheels 53 is two. The first positioning wheel 51 and the two first traveling wheels 53 are both located in the central area at the bottom of the frame 10, and the first positioning wheel 51 is located at the first central plane of the frame 10, and the two first traveling wheels 53 are located on opposite sides of the first positioning wheel 51.

[0084] The first traveling wheel 53 travels along the ground, and the first traveling wheel 53 drives the frame 10 to travel from the loading area to the security inspection area. When the frame 10 travels close to the first track 61, the frame 10 is adjusted so that the first positioning wheel 51 is centered with the first track 61. As the first traveling wheel 53 rolls along the ground, the first positioning wheel 51 gradually approaches the first track 61. During the continuous rolling of the first traveling wheel 53 along the ground, the first positioning wheel 51 first contacts the rear end of the first track 61. During the movement of the first positioning wheel 51 along the running surface of the first track 61, the first positioning wheel 51 gradually approaches the positioning portion until the first positioning wheel 51 moves to the position where the positioning portion is located, and the first positioning wheel 51 abuts against the positioning portion. At this time, the first positioning wheel 51 is in positioning cooperation with the positioning portion, and the first traveling wheel 53 stops moving along the ground. When the first positioning wheel 51 is in positioning cooperation with the positioning portion, the first traveling wheel 53 is in contact with the ground, or the first traveling wheel 53 can also be in a separated state from the ground, that is, the first traveling wheel 53 is not in contact with the ground.

[0085] It can be understood that the first traveling wheel 53 can be used to realize the movement of the frame 10 between the loading area and the security inspection area. When neither the first traveling wheel 53 nor the first positioning wheel 51 is traveling on the first track 61, the radially lowest point of the first positioning wheel 51 is higher than the radially lowest point of the first traveling wheel 53, so that only the first traveling wheel 53 is in contact with the ground, thereby driving the frame 10 to move, and the first positioning wheel 51 does not need to contact the ground. Thus, the wear of the first positioning wheel 51 can be avoided, and the replacement frequency of the first positioning wheel 51 can be reduced.

[0086] It can be understood that the first positioning wheel 51 and the first traveling wheel 53 are spaced apart along the width direction of the frame 10. When the first positioning wheel 51 travels on the first track 61, the first track 61 is spaced apart from the first traveling wheel 53. The first track 61 is provided with a positioning portion, and when the positioning portion is configured to be in positioning cooperation with the first positioning wheel 51, the first traveling wheel 53 is in contact with or separated from the ground. Similarly, it is convenient to simultaneously arrange the first traveling wheel 53 and the first positioning wheel 51 on the frame 10, and ensure that when the first positioning wheel 51 realizes the positioning function and the first traveling wheel 53 realizes the function of driving the frame 10 to move, they will not interfere with and affect each other.

[0087] According to some embodiments of the present disclosure, as Figure 2 shown, the traveling wheel assembly may further include a second traveling wheel 54, the second traveling wheel 54 is rotatably provided at the bottom of the frame 10, the first traveling wheel 53 and the second traveling wheel 54 are symmetrically arranged on both sides of the frame 10 in the width direction, the positioning wheel assembly may further include a second positioning wheel 52, the second positioning wheel 52 is rotatably provided at the bottom of the frame 10, and the first positioning wheel 51 and the second positioning wheel 52 are symmetrically arranged on both sides of the frame 10 in the width direction.

[0088] Specifically, the walking wheel assembly includes a first walking wheel 53 and a second walking wheel 54. The first walking wheel 53 and the second walking wheel 54 are symmetrically distributed with respect to the first central plane of the frame 10. The first walking wheel 53 is located on the first side of the frame 10, and the second walking wheel 54 is located on the second side of the frame 10. The first walking wheel 53 and the second walking wheel 54 walk along the ground, which is beneficial to the stability during walking and can effectively prevent the frame 10 from swaying left and right.

[0089] The positioning wheel assembly includes a first positioning wheel 51 and a second positioning wheel 52. The first positioning wheel 51 and the second positioning wheel 52 are symmetrically distributed with respect to the first central plane of the frame 10. The first positioning wheel 51 is located on the first side of the frame 10, and the second positioning wheel 52 is located on the second side of the frame 10. The first positioning wheel 51 and the second positioning wheel 52 are respectively in positioning cooperation with two positioning parts, which is beneficial to the stability of positioning.

[0090] In the width direction of the frame 10, the first positioning wheel 51 and the second positioning wheel 52 can be located between the first walking wheel 53 and the second walking wheel 54; alternatively, the first walking wheel 53 and the second walking wheel 54 can be located between the first positioning wheel 51 and the second positioning wheel 52.

[0091] The first walking wheel 53 and the second walking wheel 54 in the walking wheel assembly are symmetrically arranged on both sides in the width direction of the frame 10, and the first positioning wheel 51 and the second positioning wheel 52 in the positioning wheel assembly are symmetrically arranged on both sides in the width direction of the frame 10. This can facilitate the arrangement of the walking wheel assembly and the positioning wheel assembly, and is beneficial to the stability of the walking wheel assembly during walking and the stability of the positioning of the positioning wheel assembly.

[0092] In some examples, there can be multiple groups of walking wheel assemblies. In the length direction of the frame 10, multiple groups of walking wheel assemblies are arranged at intervals at the bottom of the frame 10.

[0093] For example, the walking wheel assembly includes two groups. One group of walking wheel assemblies is arranged at the first end of the frame 10, and the other group of walking wheel assemblies is arranged at the second end of the frame 10. The walking wheel assembly can also be three groups or more than three groups. When there are multiple groups of walking wheel assemblies, multiple groups of walking wheel assemblies are arranged at intervals at the bottom of the frame 10 in the length direction of the frame 10, which is beneficial to further improving the stability of walking.

[0094] In some examples, there can be multiple groups of positioning wheel assemblies. In the length direction of the frame 10, multiple groups of positioning wheel assemblies are arranged at intervals at the bottom of the frame 10.

[0095] For example, the positioning wheel assembly includes two sets. One set of the positioning wheel assembly is disposed at the first end of the frame 10, and the other set of the positioning wheel assembly is disposed at the second end of the frame 10. The positioning wheel assembly can also be three sets or more than three sets. When there are multiple sets of the positioning wheel assembly, the multiple sets of the positioning wheel assembly are spaced along the length direction of the frame 10 at the bottom of the frame 10, which is beneficial to further improve the positioning stability.

[0096] In some examples, the loading mechanism 100 may further include a first traveling wheel 53 and a second traveling wheel 54. The first traveling wheel 53 and the second traveling wheel 54 are rollably disposed at the bottom of the frame 10 and are spaced apart along the width direction of the frame 10. The positioning wheel assembly may include a first positioning wheel 51 and a second positioning wheel 52 that are spaced apart along the width direction of the frame 10. The first positioning wheel 51 is spaced apart from the first traveling wheel 53 in the length direction of the frame 10, and the second positioning wheel 52 is spaced apart from the second traveling wheel 54 in the length direction of the frame 10. The positioning track assembly includes a first track 61 and a second track 62 that are spaced apart along the width direction of the frame 10. The running surface of the first track 61 has a ramp portion and a flat portion, and a positioning portion is provided on the flat portion. When the first positioning wheel 51 travels from the ramp portion to the flat portion and the first positioning wheel 51 is in positioning cooperation with the positioning portion, the first traveling wheel 53 contacts or separates from the ramp portion. The running surface of the second track 62 also has a ramp portion and a flat portion, and a positioning portion is provided on the flat portion. When the second positioning wheel 52 travels from the ramp portion to the flat portion and the second positioning wheel 52 is in positioning cooperation with the positioning portion, the second traveling wheel 54 contacts or separates from the ramp portion.

[0097] The first traveling wheel 53 and the second traveling wheel 54 travel along the ground, and the first traveling wheel 53 and the second traveling wheel 54 drive the frame 10 to travel from the loading area to the security inspection area. When the frame 10 travels close to the first track 61 and the second track 62, the frame 10 is adjusted so that the first positioning wheel 51 and the first traveling wheel 53 are centered with the first track 61, and the second positioning wheel 52 and the second traveling wheel 54 are centered with the second track 62. The first traveling wheel 53 travels close to the first track 61, and at the same time, the second traveling wheel 54 travels close to the second track 62. As the first traveling wheel 53 and the second traveling wheel 54 continue to move, the first positioning wheel 51 travels along the running surface of the first track 61 from the ramp portion towards the flat portion, and the second positioning wheel 52 travels along the running surface of the second track 62 from the ramp portion towards the flat portion.

[0098] During the process of the first positioning wheel 51 and the second positioning wheel 52 traveling along the flat portion, the first positioning wheel 51 and the second positioning wheel 52 gradually approach the positioning portion of the flat portion until the first positioning wheel 51 moves to the position where the positioning portion of the first track 61 is located, and the second positioning wheel 52 moves to the position where the positioning portion of the second track 62 is located. At this time, the first positioning wheel 51 and the second positioning wheel 52 are respectively in positioning cooperation with the two positioning portions.

[0099] In some specific examples, the loading mechanism 100 further includes a traveling wheel assembly. The traveling wheel assembly includes a first traveling wheel 53 and a second traveling wheel 54. The first traveling wheel 53 and the second traveling wheel 54 are rotatably provided at the bottom of the frame 10 and are spaced apart along the width direction of the frame 10. The positioning wheel assembly includes a first positioning wheel 51 and a second positioning wheel 52 that are spaced apart along the width direction of the frame 10. The first positioning wheel 51 is spaced apart from the first traveling wheel 53 along the width direction of the frame 10, and the second positioning wheel 52 is spaced apart from the second traveling wheel 54 along the width direction of the frame 10. There is a first height difference between the radially lowest points of the first positioning wheel 51 and the first traveling wheel 53, and there is a first height difference between the radially lowest points of the second positioning wheel 52 and the second traveling wheel 54. The positioning track assembly includes a first track 61 and a second track 62 that are spaced apart along the width direction of the frame 10. When the first positioning wheel 51 travels on the first track 61 and the second positioning wheel 52 travels on the second track 62, the first track 61 is spaced apart from the first traveling wheel 53, and the second track 62 is spaced apart from the second traveling wheel 54. Positioning portions are provided on both the first track 61 and the second track 62.

[0100] The first traveling wheel 53 and the second traveling wheel 54 travel along the ground, and the first traveling wheel 53 and the second traveling wheel 54 drive the frame 10 to travel from the loading area to the security inspection area. When the frame 10 travels close to the first track 61 and the second track 62, the frame 10 is adjusted so that the first positioning wheel 51 is centered with the first track 61 and the second positioning wheel 52 is centered with the second track 62. As the first traveling wheel 53 and the second traveling wheel 54 move along the ground, the first positioning wheel 51 gradually approaches the first track 61, and the second positioning wheel 52 gradually approaches the second track 62. During the continuous movement of the first traveling wheel 53 and the second traveling wheel 54 along the ground, the first positioning wheel 51 first contacts the rear end of the first track 61, and the second positioning wheel 52 first contacts the rear end of the second track 62. During the process of the first positioning wheel 51 moving along the running surface of the first track 61 and the second positioning wheel 52 moving along the running surface of the second track 62, the first positioning wheel 51 and the second positioning wheel 52 gradually approach the positioning portion until the first positioning wheel 51 moves to the position where the positioning portion of the first track 61 is located, and the first positioning wheel 51 abuts against the positioning portion. At the same time, the second positioning wheel 52 moves to the position where the positioning portion of the second track 62 is located, and the second positioning wheel abuts against the positioning portion. At this time, the first positioning wheel 51 and the second positioning wheel 52 are respectively in positioning cooperation with the two positioning portions, and the first traveling wheel 53 and the second traveling wheel 54 stop moving along the ground.

[0101] The first track 61 and the second track 62 are arranged at intervals in the width direction of the frame 10. The first traveling wheel 53 and the second traveling wheel 54 are arranged at intervals in the width direction of the frame 10. The first positioning wheel 51 and the second positioning wheel 52 are arranged at intervals in the width direction of the frame 10. Thus, it is convenient to separate the first positioning wheel 51 from the first traveling wheel 53 in the width direction of the frame 10. When the first positioning wheel 51 travels on the first track 61, the first track 61 is separated from the first traveling wheel 53. The first track 61 is provided with a positioning portion, and when the positioning portion is configured to be in positioning cooperation with the first positioning wheel 51, the first traveling wheel 53 contacts or separates from the ground. At the same time, it is convenient to separate the second positioning wheel 52 from the second traveling wheel 54 in the width direction of the frame 10. When the second positioning wheel 52 travels on the second track 62, the second track 62 is separated from the second traveling wheel 54. The second track 62 is provided with a positioning portion, and when the positioning portion is configured to be in positioning cooperation with the second positioning wheel 52, the second traveling wheel 54 contacts or separates from the ground.

[0102] Optionally, a third track 63 and a fourth track 64 are further arranged between the loading area and the security inspection area. The top surfaces of the third track 63 and the fourth track 64 are flush with the ground. During the process of the first traveling wheel 53 and the second traveling wheel 54 driving the frame 10 to travel from the loading area to the security inspection area, the first traveling wheel 53 travels along the third track 63, and the second traveling wheel 54 travels along the fourth track 64. The third track 63 and the fourth track 64 are beneficial to the smoothness of the travel of the first traveling wheel 53 and the second traveling wheel 54. It can be understood that the traveling surfaces of the first track 61 and the second track 62 are higher than the ground.

[0103] In some embodiments of the present disclosure, as Figure 1 shown, the auxiliary support bracket assembly 30 may include m auxiliary support brackets 31. The m auxiliary support brackets 31 are sequentially arranged on the frame 10 along the length direction of the frame 10. When clamping the workpiece 200, according to the number of the auxiliary support brackets 31 used, a corresponding number of clamping members 20 are configured. Each clamping member 20 is installed and matched with an auxiliary support bracket 31, where m is an integer greater than or equal to 1. It can be understood that according to the weight and volume of the workpiece 200, the number of the auxiliary support brackets 31 used can be selected on site to facilitate the smooth progress of the clamping work. The more the number of the auxiliary support brackets 31 used, the larger the weight and volume of the workpiece 200 that can be clamped. Therefore, the auxiliary support bracket assembly 30 may include m auxiliary support brackets 31. Especially when m is greater than 1, it is convenient to select the number of the auxiliary support brackets 31 used on site.

[0104] According to some embodiments of the present disclosure, as Figure 3 and Figure 4As shown, the clamping member 20 is formed into an annular structure, and the workpiece 200 is suitable for clamping into the ring of the clamping member 20. Among them, the annular clamping member 20 can be adapted to cylindrical and truncated cone-shaped workpieces 200, so that the clamping effect of the cylindrical and truncated cone-shaped workpieces 200 is better and the installation stability is high.

[0105] The structure of the auxiliary support bracket 31 is not particularly limited. Figure 5 As shown, the auxiliary support bracket 31 includes a base and a first side plate 311, a second side plate 312 and a connecting plate arranged on the base, the first side plate 311 and the second side plate 312 are arranged at intervals, an arc-shaped notch is formed at one end of the first side plate 311 and the second side plate 312 away from the base, the connecting plate is used to connect the first side plate 311 and the second side plate 312, and the connecting plate is connected to the end surfaces of the first side plate 311 and the second side plate 312. The auxiliary support bracket 31 also includes a plurality of rollers 313, the plurality of rollers 313 are arranged at intervals between the first side plate 311 and the second side plate 312, and the central axes of the plurality of rollers 313 are consistent with the central axis of the clamping member 20.

[0106] The clamping member 20 is an annular structure, and has a first surface and a second surface opposite to each other along the axial direction of the clamping member 20, and has an inner surface and an outer surface opposite to each other along the radial direction of the clamping member 20. The clamping member 20 can be an integral structure or a split structure.

[0107] The clamping member 20 is placed on the auxiliary support bracket 31, and the outer surface of the clamping member 20 is in contact with the roller 313. The multiple rollers 313 are used to support the clamping member 20. The first surface of the clamping member 20 is opposite to the first side plate 311, and the second surface of the clamping member 20 is opposite to the second side plate 312. The first side plate 311, the second side plate 312 and the connecting plate play a limiting role on the clamping member 20.

[0108] If the clamp 20 is an integral structure, after the clamp 20 is placed on the auxiliary support bracket 31, the workpiece 200 is pushed along the axis direction of the clamp 20 until the workpiece 200 passes through the through hole of the clamp 20 and moves to the target position, the surface of the workpiece 200 contacts the inner surface of the clamp 20, and the clamp 20 clamps the workpiece 200. If the clamp 20 is a split structure, the clamp 20 includes a first annular portion and a second annular portion. After the first annular portion of the clamp 20 is placed on the auxiliary support bracket 31, the workpiece 200 is placed on the first annular portion, and then the second annular portion is connected to the first annular portion by screwing or clamping to clamp the workpiece 200.

[0109] In some embodiments of the present disclosure, Figure 4As shown, a plurality of gaskets 24 are provided on the inner wall of the ring of the clamping member 20 at intervals along the circumferential direction of the clamping member 20. Among them, the gasket 24 can reduce the wear of the clamping member 20 on the workpiece 200, thereby protecting the workpiece 200.

[0110] Specifically, the gasket 24 is arc-shaped, and the gasket 24 can be made of flexible material or hard material. The workpiece 200 is placed inside the ring of the clamping member 20, and a surface contact is formed between the workpiece 200 and the gasket 24. Compared with the contact between the workpiece 200 and the inner surface of the clamping member 20, the contact area between the clamping member 20 and the workpiece 200 is greatly reduced, which is conducive to reducing the wear of the clamping member 20 on the workpiece 200, protecting the workpiece 200, and ensuring that the workpiece 200 after detection is not affected in terms of its use function.

[0111] According to some embodiments of the present disclosure, as Figure 4 shown, each gasket 24 is connected to the clamping member 20 through a claw 25, and the claw 25 is configured to be able to drive the gasket 24 to move in the radial direction of the clamping member 20. Thus, the fitting degree between the gasket 24 and the workpiece 200 can be adjusted through the claw 25, and the clamping member 20 can clamp the workpiece 200, improving the clamping stability.

[0112] Specifically, the claw 25 includes a worm, a worm gear, and a guide sleeve. The worm passes through the first surface and the second surface of the clamping member 20. The worm gear is arranged perpendicular to the worm. One end of the worm gear meshes with the worm. The guide sleeve is sleeved on the worm gear and meshes with the other end of the worm gear. The end of the other end of the worm gear is connected to the gasket 24, so that the gasket 24 can selectively move in the radial direction.

[0113] The worm can be turned at both the first surface and the second surface. Under the action of the worm, the worm gear is driven to rotate, and the rotation of the worm gear causes the guide sleeve to move in the radial direction of the clamping member 20, so that the gasket 24 approaches or moves away from the surface of the workpiece 200.

[0114] When clamping the workpiece 200, the fitting degree between the gasket 24 and the workpiece 200 is adjusted through the claw 25, so that the clamping member 20 clamps the workpiece 200, which is beneficial to improving the clamping stability. After the detection is completed, the claw 25 drives the gasket 24 to move in the radial direction of the clamping member 20 away from the workpiece 200, facilitating the removal of the workpiece 200 from the clamping member 20.

[0115] In some embodiments of the present disclosure, as Figure 4As shown, the clamping member 20 may include an upper half-ring 22 and a lower half-ring 21. The upper half-ring 22 and the lower half-ring 21 are connected by a connecting member 23 to jointly form an annular structure. The lower half-ring 21 is adapted to be installed and cooperate with the auxiliary support bracket 31. Thus, connecting the upper half-ring 22 and the lower half-ring 21 facilitates installing the workpiece 200 onto the clamping member 20 and also facilitates removing the workpiece 200 from the clamping member 20.

[0116] Specifically, the clamping member 20 includes an upper half-ring 22 and a lower half-ring 21, and the structures of the upper half-ring 22 and the lower half-ring 21 may be the same. The lower half-ring 21 is adapted to be installed and cooperate with the auxiliary support bracket 31, that is, the lower half-ring 21 is placed at the auxiliary support bracket 31, and the outer surface of the lower half-ring 21 forms a surface contact with the surfaces of the plurality of rollers 313 of the auxiliary support bracket 31.

[0117] In some examples, the connecting member 23 may be a bolt, a screw, a pin, etc.

[0118] In some examples, the clamping member 20 is a circular ring. The upper half-ring 22 has a first connecting portion 221 and a second connecting portion 222, and both the first connecting portion 221 and the second connecting portion 222 may be plate-like bodies. The lower half-ring 21 has a third connecting portion 211 and a fourth connecting portion 212, and both the third connecting portion 211 and the fourth connecting portion 212 may be plate-like bodies. The first connecting portion 221 is connected to the third connecting portion 211 by the connecting member 23, and the second connecting portion 222 is connected to the fourth connecting portion 212 by the connecting member 23. The first connecting portion 221 and the second connecting portion 222 are located at one end of the diameter of the circular ring, and the third connecting portion 211 and the fourth connecting portion 212 are located at the other end of the diameter of the circular ring. Through holes are provided on both the first connecting portion 221, the second connecting portion 222, the third connecting portion 211, and the fourth connecting portion 212, and the connecting member 23 is a combination of a bolt and a nut.

[0119] When clamping the workpiece 200, first place the workpiece 200 at the lower half-ring 21, adjust the position of the workpiece 200, then buckle the upper half-ring 22 onto the workpiece 200, adjust the centering positions of the first connecting portion 221 and the third connecting portion 211 and the centering positions of the second connecting portion 222 and the fourth connecting portion 212, and then connect the first connecting portion 221 and the third connecting portion 211 and the second connecting portion 222 and the fourth connecting portion 212 by bolts and nuts. Thus, the workpiece 200 is clamped within the ring of the clamping member 20, and the clamping process is convenient to operate.

[0120] After the workpiece 200 is inspected, remove the bolts and nuts at the four connecting portions, and then remove the upper half-ring 22, and the workpiece 200 can be removed from the clamping member 20, and the operation process is convenient.

[0121] According to some embodiments of the present disclosure, such as Figure 3 and Figure 5As shown, the portion of each auxiliary support bracket 31 that cooperates with the clamping member 20 is formed as a partially annular structure adapted to the clamping member 20. A pressing member 314 is provided on the partially annular structure. When the clamping member 20 is installed and cooperated with the partially annular structure, the pressing member 314 is in contact and cooperation with the clamping member 20. Thus, the pressing member 314 can achieve the purpose of pressing the clamping member 20 and can provide stable support for the clamping member 20.

[0122] Specifically, the auxiliary support bracket 31 includes a first side plate 311, a second side plate 312, and a plurality of rollers 313. The pressing member 314 can be provided on the first side plate 311, or the pressing member 314 can be provided on the second side plate 312, or the pressing member 314 can be provided on both the first side plate 311 and the second side plate 312.

[0123] In some examples, the pressing member 314 can be a pressing bolt. There are a plurality of pressing bolts, and the plurality of pressing bolts are spaced apart along the circumferential direction of the partially annular structure.

[0124] A plurality of pressing bolts are spaced and provided on the first side plate 311, and a plurality of pressing bolts are spaced and provided on the second side plate 312. Place the lower half ring 21 on the auxiliary support bracket 31. The first surface of the lower half ring 21 faces the first side plate 311, and the second surface of the lower half ring 21 faces the second side plate 312. Adjust the pressing bolts on the first side plate 311 so that the pressing bolts abut against the first surface of the lower half ring 21, and adjust the pressing bolts on the second side plate 312 so that the pressing bolts abut against the second surface of the lower half ring 21. Then place the workpiece 200 and the upper half ring 22.

[0125] Through the pressing bolts on the first side plate 311 and the second side plate 312, the lower half ring 21 can be stably fixed on the auxiliary support bracket 31, which is conducive to the smooth clamping of the workpiece 200.

[0126] According to some embodiments of the present disclosure, as Figure 1 shown, the support roller assembly 40 can include n support roller members 41. The n support roller members 41 are sequentially arranged on the frame 10 along the length direction of the frame 10. When the clamping member 20 and the workpiece 200 are integrally migrated, each clamping member 20 is installed and cooperated with a support roller member 41, where n is an integer greater than or equal to 1. It can be understood that setting n support roller members 41, especially when n is greater than 1, can make the support for the clamping member 20 and the workpiece 200 stable and facilitate the smooth progress of safety detection.

[0127] The number of auxiliary support brackets 31 and support roller members 41 is set according to actual requirements. For example, the number of auxiliary support brackets 31 is two, and the number of support roller members 41 is also two. One auxiliary support bracket 31 is located at the first end of the frame 10, and the other auxiliary support bracket 31 is located at the second end of the frame 10. The two support roller members 41 are located between the two auxiliary support brackets 31.

[0128] In some embodiments of the present disclosure, as Figure 1 and Figure 2 shown, each support roller member 41 may include a base 411 and two support rollers 412. Among them, the base 411 is provided on the frame 10; in the width direction of the frame 10, the two support rollers 412 are spaced apart on the base 411, and the clamping member 20 is adapted to be clamped between the two support rollers 412.

[0129] Specifically, the outer circumferential surface of the clamping member 20 is clamped between the two support rollers 412. Thus, it is convenient to stably mount the clamping member 20 on the support roller assembly 40. The base 411 is convenient for arranging the two support rollers 412 and facilitating the installation of the two support rollers 412 on the frame 10.

[0130] Optionally, the support roller 412 is rotatably provided on the base 411. One of the two support rollers 412 is connected to the motor 414. The motor 414 drives one support roller 412 to rotate, thereby driving the clamping member 20 and the other support roller 412 to rotate.

[0131] For the case where the workpiece 200 needs to be circumferentially detected, during the detection process, the motor 414 is started to drive the clamping member 20 and the workpiece 200 to rotate to meet the detection requirements. For the case where the workpiece 200 does not need to be circumferentially detected, during the detection process, the motor 414 is turned off.

[0132] In some embodiments of the present disclosure, as Figure 1 shown, the two support rollers 412 are movably provided on the base 411 to adjust the distance between the two support rollers 412. Thus, more clamping members 20 with different size specifications can be adapted.

[0133] When the outer diameter of the clamping member 20 is relatively large, by increasing the distance between the two support rollers 412 and increasing the support angle of the two support rollers 412 for the clamping member 20, the stability of the support is improved.

[0134] According to some embodiments of the present disclosure, as Figure 1 shown, each support roller member 41 may further include an axial stop 413. In the length direction of the frame 10, the axial stop 413 is provided at one end of the base 411 for limiting the clamping member 20. Thus, the accurate installation position of the clamping member 20 can be ensured, and the security inspection accuracy rate of the workpiece 200 can be improved.

[0135] For example, the number of the supporting roller members 41 is two, and the two supporting roller members 41 are defined as a first supporting roller member and a second supporting roller member respectively. The two clamping members 20 and the workpiece 200 are placed on the first supporting roller member and the second supporting roller member. The shaft stopper 413 on the first supporting roller member abuts against the second surface of one clamping member 20, and the shaft stopper 413 on the second supporting roller member abuts against the first surface of the other clamping member 20. Thereby, the horizontal movement of the two clamping members 20 can be restricted, the positions of the two clamping members 20 can be ensured to be accurate, and further, the security inspection accuracy rate of the workpiece 200 can be improved.

[0136] In some embodiments of the present disclosure, as Figure 1 shown, m auxiliary support brackets 31 are movably arranged on the frame 10, and / or n supporting roller members 41 are movably arranged on the frame 10.

[0137] In some examples, m auxiliary support brackets 31 are movably arranged on the frame 10, which can facilitate the adjustment of the distance between the auxiliary support brackets 31, so as to better meet the loading requirements of workpieces 200 of various size specifications and improve the versatility of the auxiliary support brackets 31.

[0138] In some examples, n supporting roller members 41 are movably arranged on the frame 10, which can facilitate the adjustment of the distance between the supporting roller members 41, so as to better adapt to the overall structure of the clamping members 20 and the workpiece 200 loaded on the auxiliary support brackets 31 and improve the versatility of the supporting roller members 41.

[0139] In some embodiments of the present disclosure, as Figure 1 、 Figure 2 and Figure 3 shown, a first moving member 13 is arranged on the frame 10; a second moving member is arranged on each auxiliary support bracket 31, and / or a third moving member is arranged on each supporting roller member 41. The second moving member is movably matched with the first moving member 13, and the third moving member is movably matched with the first moving member 13. Thereby, it can be facilitated to realize that m auxiliary support brackets 31 are movably arranged on the frame 10, and / or n supporting roller members 41 are movably arranged on the frame 10.

[0140] Further, the first moving member 13 extends along the length direction of the frame 10. The first moving member 13 can be a chain, and both the second moving member and the third moving member can be sprockets; the first moving member 13 can also be one of a chute and a slide rail, the second moving member can be the other of the chute and the slide rail, and the third moving member can be the other of the chute and the slide rail.

[0141] As Figure 6 shown, according to the method for security inspection by applying the above loading mechanism 100 according to the embodiments of the present disclosure, the security inspection method includes operations S110 to S130.

[0142] In operation S110, the workpiece 200 to be loaded is clamped by the clamping member 20, wherein the clamping member 20 is mounted on the auxiliary support bracket assembly 30.

[0143] In operation S120, the clamping member 20 and the workpiece 200 as a whole are lifted and transferred to the support roller assembly 40.

[0144] In operation S130, the frame 10 carries the workpiece 200 to move to the security inspection area to perform a security inspection on the workpiece 200.

[0145] Specifically, the structures of the frame 10, the clamping member 20, the auxiliary support bracket assembly 30, and the support roller assembly 40 are as described above and will not be elaborated here. Taking the auxiliary support bracket assembly 30 including two auxiliary support brackets 31 and the support roller assembly 40 including a first support roller member and a second support roller member as an example, the security inspection method will be described in detail below.

[0146] In the loading area, the distance between the two auxiliary support brackets 31 is adjusted by moving the auxiliary support brackets 31. After adjusting the distance between the two auxiliary support brackets 31, the two lower half-rings 21 are respectively placed on the two auxiliary support brackets 31, and the workpiece 200 is placed on the inner surfaces of the two lower half-rings 21. The position of the workpiece 200 is adjusted so that one lower half-ring 21 contacts the workpiece 200 at approximately one-fourth of the length direction, and the other lower half-ring 21 contacts the workpiece 200 at approximately three-fourths of the length direction. Then, the two upper half-rings 22 are connected to the two lower half-rings 21 in one-to-one correspondence to clamp the workpiece 200.

[0147] The two clamping members 20 and the workpiece 200 are lifted by a lifting device, and the two auxiliary support brackets 31 are moved so that the two auxiliary support brackets 31 are away from the first support roller member and the second support roller member. The distance between the first support roller member and the second support roller member is adjusted by moving the first support roller member and the second support roller member so that the distance between the first support roller member and the second support roller member is adapted to the distance between the two clamping members 20. After adjusting the distance between the first support roller member and the second support roller member, the two clamping members 20 and the workpiece 200 are lifted by the lifting device so that one clamping member 20 contacts the two support rollers 412 of the first support roller member, and the other clamping member 20 contacts the two support rollers 412 of the second support roller member.

[0148] After that, the two sets of walking wheel assemblies drive the frame 10 to travel from the loading area to the security inspection area. When the frame 10 travels to a position close to the first track 61 and the second track 62, the first positioning wheel 51 and the second positioning wheel 52 respectively travel along the first track 61 and the second track 62 until the first positioning wheel 51 travels to the positioning portion of the first track 61 and the second positioning wheel 52 travels to the positioning portion of the second track 62. The first positioning wheel 51 and the second positioning wheel 52 are in positioning cooperation with the two positioning portions, and the frame 10 is fixed at the security inspection area.

[0149] After the frame 10 is fixed at the security inspection area by the first positioning wheel 51 and the second positioning wheel 52, the radiation source and the detector located at the security inspection area perform a security inspection on the workpiece 200. The radiation source can emit X-rays, and the security inspection of the workpiece 200 is performed by the X-rays.

[0150] According to the security inspection method of the present disclosure, the operation of loading the workpiece 200 can be completed on the auxiliary support bracket assembly 30. After loading, the overall migration of the clamping member 20 and the workpiece 200 to the support roller assembly 40 can reduce the wear on the support roller assembly 40. Since the support roller assembly 40 is a support structure for supporting the workpiece 200 for security inspection, reducing the wear on the support roller assembly 40 can ensure the security inspection accuracy of the workpiece 200. Reducing the wear on the support roller assembly 40 can also reduce the replacement frequency of the support roller assembly 40, thereby saving manpower and material resources and improving the security inspection efficiency of the workpiece 200.
