Description

Technical Field

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

[0002] CT technology plays an important role in security inspections because it can eliminate the impact of overlapping objects. CT equipment is also widely used in technical fields such as object detection. CT equipment can not only detect smaller items such as luggage and air boxes, but also larger items such as containers and vehicles.

[0003] In related technologies, CT equipment obtains projection data at different angles by rotating the X-ray machine and detector, and obtains tomographic images through reconstruction methods, thereby obtaining internal information of the inspected object. In combination with dual-energy or multi-energy imaging technology, the atomic number and electron density of the inspected material can be reconstructed to identify the type of material, which has a good effect in the detection of explosives, dangerous goods, etc.

[0004] For example, in the related technology, in some special application scenarios, due to the particularity of the detected object, the CT equipment is set in a designated area, and the detected object needs to be delivered to the designated area before the detected object can be scanned by CT. In this process, the detected object needs to be loaded onto the loading mechanism, and the loading mechanism drives the detected object to move to the designated area. The support assembly of the existing loading mechanism is used to clamp the detected object. Since the detected object needs to adjust its relative position with the support assembly when it is loaded onto the support assembly, the support assembly will be greatly worn after a long period of use. After the support assembly is worn, it will affect the accuracy of the CT scan of the detected object. 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 CT scanning.

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 technology, in some special application scenarios, due to the particularity of the detected object, the CT equipment is set in a designated area, and the detected object needs to be delivered to the designated area before the detected object can be scanned by CT. In this process, the detected object needs to be loaded onto the loading mechanism, and the loading mechanism drives the detected object to move to the designated area. The support assembly of the existing loading mechanism is used to clamp the detected object. Since the relative position of the detected object with the support assembly needs to be adjusted when it is loaded onto the support assembly, the support assembly will be greatly 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 object. 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 CT scanning.

[0056] Reference below Figure 1-Figure 6 A loading mechanism 100 for X-ray inspection and a method for safety inspection according to an embodiment of the present disclosure are described.

[0057] like Figure 1 As shown, the loading mechanism 100 according to the 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, referring to Figure 1 The frame 10 is configured to move between the loading area and the 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 installed and matched 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 installed and matched with the clamping member 20, wherein, in the loading area, when the clamping member 20 is installed and matched with the auxiliary support bracket assembly 30, it is suitable to clamp the workpiece 200 to the clamping member 20, after the clamping member 20 clamps the workpiece 200, it is suitable to move 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 matched with the support roller assembly 40, the frame 10 is suitable to move to the security inspection area.

[0059] It is understandable that in the field of security inspection, in order to facilitate the smooth security inspection of items, a loading area and a security inspection area will be set up. In the embodiment of the present disclosure, the item to be inspected is named as a workpiece 200, the loading area is used to store the workpiece 200, and the security inspection area is used to perform security inspection on the workpiece 200. Therefore, during the security inspection, the loading mechanism 100 is required to load the workpiece 200 in the loading area. After loading the workpiece 200, the workpiece 200 is transported to the security inspection area for a security inspection on the workpiece 200.

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

[0061] When loading the workpiece 200, the loading mechanism 100 stops at the loading area, the clamping member 20 is placed on the auxiliary support bracket assembly 30, and the workpiece 200 is clamped to the clamping member 20. During the clamping process of 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 accurate detection. The auxiliary support bracket assembly 30 is configured to be able to be installed and matched with the clamping member 20, so that the clamping member 20 can be stably placed 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 can be moved as a whole to the support roller assembly 40, where 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 matched with the clamping member 20, which can facilitate the clamping member 20 to be stably placed on the support roller assembly 40. After the clamping member 20 and the workpiece 200 are moved 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 safely inspected.

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

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

[0065] In the process of clamping the workpiece 200 by the clamping member 20, by configuring the auxiliary support bracket assembly 30 to be able to be installed and matched with the clamping member 20, the clamping member 20 can be stably placed on the auxiliary support bracket assembly 30, thereby facilitating the clamping of the workpiece 200. In 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 able to be installed and matched with the clamping member 20, the clamping member 20 can be stably placed on the support roller assembly 40.

[0066] According to the loading mechanism 100 of the 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 after loading, the clamping member 20 and the workpiece 200 are moved as a whole to the support roller assembly 40, which can reduce the wear of the support roller assembly 40. Since the support roller assembly 40 is a supporting 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, Figure 1 As shown, a first positioning assembly is provided at the bottom of the frame 10, and a second positioning assembly is provided in the security inspection area. When the frame 10 moves to the security inspection area, the first positioning assembly is adapted to cooperate with the second positioning assembly to position the frame 10. The positioning positions of the first positioning assembly and the second positioning assembly can be positions suitable for security inspection, thereby allowing the loading mechanism 100 to be docked at a position suitable for security inspection, facilitating the smooth conduct of security inspection work while ensuring the accuracy of security inspection.

[0068] In some embodiments of the present disclosure, Figure 1 and Figure 2 As shown, the first positioning assembly can be a positioning wheel assembly, which can be rotatably arranged on the frame 10, and the second positioning assembly can be a positioning rail assembly, and a positioning portion is provided on the walking surface of the positioning rail assembly. When the positioning wheel assembly moves on the walking surface to the positioning portion, the positioning wheel assembly is positioned and matched with the positioning rail assembly.

[0069] The frame 10 has a length direction and a width direction. Figure 1 As shown in the D1 direction, the width direction is as Figure 2The two opposite ends of the frame 10 defined along the length direction of the frame 10 are the first end of the frame 10 and the second end of the frame 10, respectively. The two opposite sides of the frame 10 defined along the width direction of the frame 10 are the first side of the frame 10 and the second side of the frame 10, respectively. The frame 10 has a first center plane and a second center plane. The direction of the first center plane is consistent with the length direction. The first side and the second side are located on both sides of the first center plane. The direction of the second center plane is consistent with the width direction. The first end and the second end are located on both sides of the second center 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 vicinity of the second center 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, and 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 which matches the number of positioning wheels, and the positioning track is fixed to the security inspection area. The positioning wheel can move along the walking surface of the positioning track, and a positioning portion is provided 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 moves to the position where the positioning portion is located, the positioning wheel conflicts with the positioning portion, and the positioning portion can limit the movement of the positioning wheel in the front-rear direction of the security inspection area, thereby allowing the rack 10 to dock at a fixed position in the security inspection area.

[0072] It is understandable that, through the cooperation of the positioning wheel assembly and the positioning rail assembly, it is easy to cooperate the first positioning assembly with the second positioning assembly to position the frame 10. Since the positioning wheel assembly is rollably arranged on the frame 10, when the positioning wheel assembly is cooperated with the positioning part, the positioning wheel assembly can roll to the positioning part on the walking surface, which is easy to implement and saves time and effort.

[0073] According to some embodiments of the present disclosure, Figure 1 and Figure 2As shown, the loading mechanism 100 may further include a wheel assembly, which may include a first wheel 53, which is rollably disposed at the bottom of the frame 10. The positioning wheel assembly may include a first positioning wheel 51, which is rollably disposed at the bottom of the frame 10, and the first positioning wheel 51 and the first wheel 53 are spaced apart in the length direction of the frame 10. With the ground as a reference, the radial lowest point of the first positioning wheel 51 is higher than the radial lowest point of the first wheel 53. The positioning track assembly at least includes a first track 61, the running surface of the first track 61 has a slope and a gentle portion, and a positioning portion is provided on the gentle portion, and the first positioning wheel 51 travels from the slope to the gentle portion, and when the first positioning wheel 51 is positioned and matched with the positioning portion, the first wheel 53 contacts or separates from the slope.

[0074] Specifically, the top surface of the first track 61 is located above the ground, and along the travel direction of the rack 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 needs, and the inclination angle of the slope portion can 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] The first positioning wheel 51 and the first traveling wheel 53 can both be rotatably installed at the bottom of the frame 10. In the vertical direction, the radial lowest point of the first positioning wheel 51 is higher than the radial lowest point of the first traveling wheel 53. Therefore, 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 wheel 51 and the first running wheel 53 is set according to actual needs. For example, the number of the first positioning wheel 51 and the first running wheel 53 is one, and the first positioning wheel 51 and the first running wheel 53 are installed in the central area of ​​the bottom of the frame 10. The number of the first track 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 wheel assembly, which may include a first wheel 53, which is rollably disposed at the bottom of the frame 10. The positioning wheel assembly may include a first positioning wheel 51, which is rollably disposed at the bottom of the frame 10, the first positioning wheel 51 and the first wheel 53 are spaced apart along the width direction of the frame 10, and the radial lowest point of the first positioning wheel 51 is higher than the radial lowest point of the first wheel 53 with the ground as a reference. The positioning track assembly includes at least a first track 61, and when the first positioning wheel 51 travels on the first track 61, the first track 61 is spaced apart from the first wheel 53, and a positioning portion is provided on the first track 61, and when the positioning portion is configured to be positioned and matched with the first positioning wheel 51, the first wheel 53 contacts or separates from the ground.

[0081] Specifically, the top surface of the first track 61 is located above the ground, and the end of the walking surface of the first track 61 is configured with a protruding positioning portion.

[0082] The first positioning wheel 51 and the first running wheel 53 are arranged at intervals along the width direction of the frame 10. Both the first positioning wheel 51 and the first running wheel 53 are rotatably mounted on the bottom of the frame 10, and along the vertical direction, 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 when the first running wheel 53 runs along the ground, the first positioning wheel 51 does not contact the ground.

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

[0084] The first running wheel 53 runs along the ground, and the first running 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 aligned with the first track 61. As the first running wheel 53 rolls along the ground, the first positioning wheel 51 gradually approaches the first track 61. In the process of the first running wheel 53 continuing to roll along the ground, the first positioning wheel 51 first contacts the rear end of the first track 61. In the process of the first positioning wheel 51 moving along the running surface of the first track 61, the first positioning wheel 51 gradually approaches the positioning part until the first positioning wheel 51 moves to the position of the positioning part, and the first positioning wheel 51 conflicts with the positioning part. At this time, the first positioning wheel 51 is positioned and matched with the positioning part, and the first running wheel 53 stops moving along the ground. When the first positioning wheel 51 is positioned and matched with the positioning part, the first running wheel 53 contacts the ground. The first running wheel 53 can also be in a separated state from the ground, that is, the first running wheel 53 does not contact the ground.

[0085] It can be understood that the first traveling wheel 53 can be used to enable the frame 10 to move between the loading area and the security inspection area. When neither the first traveling wheel 53 nor the first positioning wheel 51 is running 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 traveling wheel 53 so that only the first traveling wheel 53 is in contact with the ground, thereby driving the frame 10 to move. 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.

[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. A positioning portion is provided on the first track 61. The positioning portion is configured to be positioned with the first positioning wheel 51 so that the first traveling wheel 53 is in contact with or separated from the ground. It is also convenient to simultaneously set the first traveling 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 traveling wheel 53 does not interfere with or affect each other when realizing the function of driving the frame 10 to move.

The positioning wheel assembly may further include a second positioning wheel 52, which is rollably disposed at the bottom of the frame 10, and the first positioning wheel 51 and the second positioning wheel 52 are centrally symmetrically arranged on both sides of the width direction of the frame 10.

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

[0089] The positioning wheel assembly includes a first positioning wheel 51 and a second positioning wheel 52, which are symmetrically distributed about the first center 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 positioned and matched with the two positioning parts, which is beneficial to the stability of positioning.

[0090] Along the width direction of the frame 10 , the first positioning wheel 51 and the second positioning wheel 52 may be located between the first running wheel 53 and the second running wheel 54 ; or the first running wheel 53 and the second running wheel 54 may be located between the first positioning wheel 51 and the second positioning wheel 52 .

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

[0092] In some examples, there may be multiple groups of traveling wheel assemblies, and in the length direction of the frame 10 , the multiple groups of traveling 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. In the case where there are multiple groups of walking wheel assemblies, the multiple groups of walking wheel assemblies are arranged at intervals at the bottom of the frame 10 along the length direction of the frame 10, which is conducive to further improving the walking stability.

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

[0095] For example, the positioning wheel assembly includes two groups, one group of positioning wheel assemblies is arranged at the first end of the frame 10, and the other group of positioning wheel assemblies is arranged at the second end of the frame 10. The positioning wheel assembly can also be three groups or more. In the case where the positioning wheel assembly is a plurality of groups, the plurality of groups of positioning wheel assemblies are arranged at intervals at the bottom of the frame 10 along the length direction of the frame 10, which is conducive to further improving the stability of positioning.

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

[0097] The first running wheel 53 and the second running wheel 54 run along the ground, and the first running wheel 53 and the second running wheel 54 drive 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 and the second track 62, the frame 10 is adjusted so that the first positioning wheel 51 and the first running wheel 53 are centered with the first track 61, and the second positioning wheel 52 and the second running wheel 54 are centered with the second track 62. The first running wheel 53 runs close to the first track 61, and the second running wheel 54 runs close to the second track 62. As the first running wheel 53 and the second running wheel 54 continue to move, the first positioning wheel 51 runs along the running surface of the first track 61 from the sloped part to the flat part, and the second positioning wheel 52 runs along the running surface of the second track 62 from the sloped part to the flat part.

[0098] In the process of the first positioning wheel 51 and the second positioning wheel 52 moving 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 of the positioning portion of the first track 61, and the second positioning wheel 52 moves to the position of the positioning portion of the second track 62. At this time, the first positioning wheel 51 and the second positioning wheel 52 are respectively positioned and cooperated with the two positioning portions.

[0099] In some specific examples, the loading mechanism 100 further includes a wheel assembly, which includes a first wheel 53 and a second wheel 54, which 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 includes a first positioning wheel 51 and a second positioning wheel 52 spaced apart along the width direction of the frame 10, the first positioning wheel 51 is spaced apart from the first wheel 53 along the width direction of the frame 10, the second positioning wheel 52 is spaced apart from the second wheel 54 along the width direction of the frame 10, and there is a first height difference between the radial lowest point of the first positioning wheel 51 and the first wheel 53, and there is a first height difference between the radial lowest point of the second positioning wheel 52 and the second wheel 54. The positioning rail assembly includes a first rail 61 and a second rail 62 which are spaced apart along the width direction of the frame 10. When the first positioning wheel 51 runs on the first rail 61 and the second positioning wheel 52 runs on the second rail 62, the first rail 61 is spaced apart from the first running wheel 53, and the second rail 62 is spaced apart from the second running wheel 54. Positioning parts are provided on both the first rail 61 and the second rail 62.

[0100] The first running wheel 53 and the second running wheel 54 run along the ground, and the first running wheel 53 and the second running 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 running wheel 53 and the second running 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. In the process of the first running wheel 53 and the second running wheel 54 continuing to move 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. In the process of the first positioning wheel 51 moving along the walking surface of the first track 61 and the second positioning wheel 52 moving along the walking 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 of the positioning portion of the first track 61, and the first positioning wheel 51 conflicts with the positioning portion. At the same time, the second positioning wheel 52 moves to the position of the positioning portion of the second track 62, and the second positioning wheel conflicts with the positioning portion. At this time, the first positioning wheel 51 and the second positioning wheel 52 are respectively positioned and matched with the two positioning portions, and the first walking wheel 53 and the second walking wheel 54 stop moving along the ground.

[0101] The first rail 61 and the second rail 62 are arranged at intervals along the width direction of the frame 10, the first running wheel 53 and the second running wheel 54 are arranged at intervals along the width direction of the frame 10, and the first positioning wheel 51 and the second positioning wheel 52 are arranged at intervals along the width direction of the frame 10. This can facilitate the first positioning wheel 51 and the first running wheel 53 to be spaced apart along the width direction of the frame 10, when the first positioning wheel 51 runs on the first rail 61, the first rail 61 and the first running wheel 53 are spaced apart, the first rail 61 is provided with a positioning part, and the positioning part is configured to be positioned and matched with the first positioning wheel 51, when the first running wheel 53 contacts or separates from the ground.

When the first running wheel 53 and the second running wheel 54 drive the rack 10 from the loading area to the security inspection area, the first running wheel 53 runs along the third track 63, and the second running wheel 54 runs along the fourth track 64. The third track 63 and the fourth track 64 are conducive to the stability of the running of the first running wheel 53 and the second running wheel 54. It can be understood that the running surface of the first track 61 and the running surface of the second track 62 are higher than the ground.

[0103] In some embodiments of the present disclosure, Figure 1 As shown, the auxiliary support bracket assembly 30 may include m auxiliary support brackets 31, and 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, a corresponding number of clamping members 20 are configured according to the number of auxiliary support brackets 31 used, and each clamping member 20 is installed and matched with an auxiliary support bracket 31, wherein 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 auxiliary support brackets 31 used can be selected on site to facilitate the smooth progress of the clamping work. The more the number of auxiliary support brackets 31 used, the heavier and larger the workpiece 200 can be clamped. Therefore, the auxiliary support bracket assembly 30 may include m auxiliary support brackets 31, and especially when m is greater than 1, it is convenient to select the number of auxiliary support brackets 31 used on site.

[0104] According to some embodiments of the present disclosure, 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 spaced apart along the circumference of the clamping member 20 are provided on the inner wall of the ring of the clamping member 20. The gaskets 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 can be made of a flexible material or a hard material. The workpiece 200 is placed in the ring of the clamp 20, and the workpiece 200 and the gasket 24 form a surface contact. Compared with the contact between the workpiece 200 and the inner surface of the clamp 20, the contact area between the clamp 20 and the workpiece 200 is greatly reduced, which is conducive to reducing the wear of the clamp 20 on the workpiece 200, and is conducive to protecting the workpiece 200, ensuring that the workpiece 200 after detection is not affected in terms of use function.

[0111] According to some embodiments of the present disclosure, Figure 4 As shown, each gasket 24 is connected to the clamping member 20 through a claw 25, and the claw 25 is configured to drive the gasket 24 to move in the radial direction of the clamping member 20. Therefore, the fit between the gasket 24 and the workpiece 200 can be adjusted through the claw 25, so that the clamping member 20 can clamp the workpiece 200 and improve the clamping stability.

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

[0113] The worm can be screwed at both the first surface and the second surface, and the worm wheel is driven to rotate under the action of the worm. The rotation of the worm wheel causes the guide sleeve to move in the radial direction of the clamp 20 to make the gasket 24 approach or move away from the surface of the workpiece 200.

[0114] When clamping the workpiece 200, the clamping claw 25 adjusts the fit between the gasket 24 and the workpiece 200, so that the clamping member 20 clamps the workpiece 200, which is conducive to improving the stability of the clamping. After the inspection is completed, the clamping claw 25 drives the gasket 24 to move in the radial direction of the clamping member 20 away from the workpiece 200, so as to facilitate the removal of the workpiece 200 from the clamping member 20.

[0115] In some embodiments of the present disclosure, 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 form a ring structure, and the lower half ring 21 is suitable for installation and cooperation with the auxiliary support bracket 31. Thus, the connection between the upper half ring 22 and the lower half ring 21 can facilitate the installation of the workpiece 200 on the clamping member 20, and can also facilitate the removal of 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 can be the same. The lower half ring 21 is suitable for being installed and matched 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 surface of the plurality of rollers 313 of the auxiliary support bracket 31.

[0117] In some examples, the connector 23 may be a bolt, a screw, a pin, or the like.

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

[0119] When clamping the workpiece 200, first place the workpiece 200 on the lower half ring 21, adjust the position of the workpiece 200, then buckle the upper half ring 22 on the workpiece 200, adjust the centering position of the first connecting portion 221 and the third connecting portion 211 and the centering position 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. In this way, the workpiece 200 is clamped in the ring of the clamping member 20, and the clamping process is convenient to operate.

[0120] After the workpiece 200 is inspected, the bolts and nuts at the four connecting parts are removed, and then the upper half ring 22 is removed, 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, Figure 3 and Figure 5As shown, the part of each auxiliary support bracket 31 that matches with the clamping member 20 is formed into a partial annular structure that matches with the clamping member 20, and a pressing member 314 is provided on the partial annular structure. When the clamping member 20 is installed and matched with the partial annular structure, the pressing member 314 contacts and matches with the clamping member 20. Therefore, the pressing member 314 can achieve the purpose of tightening the clamping member 20 and 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 tensioning member 314 can be arranged on the first side plate 311, the tensioning member 314 can also be arranged on the second side plate 312, or the tensioning member 314 can be arranged on both the first side plate 311 and the second side plate 312.

[0123] In some examples, the tightening member 314 may be a tightening bolt, and there may be a plurality of tightening bolts, which are spaced apart along the circumference of the partial annular structure.

[0124] A plurality of jacking bolts are arranged at intervals on the first side plate 311, and a plurality of jacking bolts are arranged at intervals on the second side plate 312. The lower half ring 21 is placed on the auxiliary support bracket 31, with the first surface of the lower half ring 21 facing the first side plate 311, and the second surface of the lower half ring 21 facing the second side plate 312. The jacking bolts on the first side plate 311 are adjusted so that the jacking bolts are in conflict with the first surface of the lower half ring 21, and the jacking bolts on the second side plate 312 are adjusted so that the jacking bolts are in conflict with the second surface of the lower half ring 21. Then the workpiece 200 and the upper half ring 22 are placed.

[0125] Through the tightening 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 , thereby facilitating the smooth clamping of the workpiece 200 .

[0126] According to some embodiments of the present disclosure, Figure 1 As shown, the support roller assembly 40 may include n support roller members 41, which 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 moved as a whole, each clamping member 20 is installed and matched with a support roller member 41, wherein n is an integer greater than or equal to 1. It can be understood that by providing n support roller members 41, especially when n is greater than 1, the support of the clamping member 20 and the workpiece 200 can be stable, which facilitates the smooth implementation of safety inspection.

[0127] The number of the auxiliary support brackets 31 and the support roller members 41 is set according to actual needs, for example, the number of the auxiliary support brackets 31 is two, and the number of the 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, and the two support roller members 41 are located between the two auxiliary support brackets 31.

[0128] In some embodiments of the present disclosure, Figure 1 and Figure 2 As shown, each supporting roller member 41 may include a base 411 and two supporting rollers 412 , wherein the base 411 is disposed on the frame 10 ; in the width direction of the frame 10 , the two supporting rollers 412 are spaced apart from each other on the base 411 , and the clamping member 20 is suitable for being clamped between the two supporting rollers 412 .

[0129] Specifically, the outer annular surface of the clamping member 20 is clamped between the two support rollers 412. Thus, the clamping member 20 can be stably installed on the support roller assembly 40, and the base 411 can facilitate the arrangement of the two support rollers 412 and the installation of the two support rollers 412 on the frame 10.

[0130] Optionally, the support roller 412 is rotatably disposed on the base 411 , and 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] In the case where the workpiece 200 needs to be inspected circumferentially, during the inspection process, the motor 414 is started to drive the clamping member 20 and the workpiece 200 to rotate to meet the inspection requirements. In the case where the workpiece 200 does not need to be inspected circumferentially, during the inspection process, the motor 414 is turned off.

[0132] In some embodiments of the present disclosure, Figure 1 As shown, the two support rollers 412 are movably arranged on the base 411 to adjust the distance between the two support rollers 412. Thus, the clamping member 20 of more sizes can be adapted.

[0133] When the outer diameter of the clamping member 20 is relatively large, the support angle of the two support rollers 412 to the clamping member 20 is increased by increasing the distance between the two support rollers 412, which is beneficial to the stability of the support.

[0134] According to some embodiments of the present disclosure, Figure 1 As shown, each supporting roller member 41 may further include an axle stopper 413, which is disposed at one end of the base 411 in the length direction of the frame 10, and is used to limit the position of the clamping member 20. This ensures that the position of the clamping member 20 is accurately installed, thereby improving the accuracy of the security inspection of the workpiece 200.

[0135] For example, the number of the supporting rollers 41 is two, and the two supporting rollers 41 are defined as the first supporting roller and the second supporting roller. The two clamping members 20 and the workpiece 200 are placed on the first supporting roller and the second supporting roller, and the shaft stopper 413 on the first supporting roller contacts the second surface of one clamping member 20, and the shaft stopper 413 on the second supporting roller contacts the first surface of the other clamping member 20, thereby limiting the horizontal movement of the two clamping members 20, ensuring the accurate position of the two clamping members 20, and further facilitating the improvement of the accuracy of the security inspection of the workpiece 200.

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

[0137] In some examples, m auxiliary support brackets 31 are movably disposed on the frame 10 , which can facilitate adjustment of the distance between the auxiliary support brackets 31 , thereby better meeting the loading requirements of workpieces 200 of various sizes and specifications, and improving the versatility of the auxiliary support brackets 31 .

[0138] In some examples, n support rollers 41 are movably disposed on the frame 10, which can facilitate adjustment of the distance between the support rollers 41, so as to better adapt to the overall structure of the clamping member 20 and the workpiece 200 loaded on the auxiliary support bracket 31, thereby improving the versatility of the support rollers 41.

[0139] In some embodiments of the present disclosure, Figure 1 , Figure 2 and Figure 3 As shown, a first moving member 13 is provided on the frame 10; a second moving member is provided on each auxiliary support bracket 31, and / or a third moving member is provided on each support 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. Thus, it is convenient to realize that m auxiliary support brackets 31 are movably provided on the frame 10, and / or n support roller members 41 are movably provided on the frame 10.

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

[0141] like Figure 6 As shown, according to the method for performing safety inspection using the above-mentioned loading mechanism 100 according to an embodiment of the present disclosure, the safety inspection method includes operations S110 to S130.

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

[0143] In operation S120 , the clamping member 20 and the workpiece 200 are hoisted and moved integrally to the supporting roller assembly 40 .

[0144] In operation S130 , the frame 10 carries the workpiece 200 and moves to the security inspection area, where a security inspection is performed 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 repeated here. The following takes 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 to describe the safety inspection method in detail.

[0146] In the loading area, the distance between the two auxiliary support brackets 31 is adjusted by moving the auxiliary support brackets 31. After the distance between the two auxiliary support brackets 31 is adjusted, 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-quarter of the length direction, and the other lower half ring 21 contacts the workpiece 200 at approximately three-quarters of the length direction, and then the two upper half rings 22 are connected to the two lower half rings 21 one by one to clamp the workpiece 200.

[0147] The two clamping members 20 and the workpiece 200 are hoisted by the hoisting equipment, 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 spacing 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 spacing between the first support roller member and the second support roller member matches the spacing between the two clamping members 20. After the spacing between the first support roller member and the second support roller member is adjusted, the two clamping members 20 and the workpiece 200 are hoisted by the hoisting equipment 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] Afterwards, the two sets of running wheel assemblies drive the frame 10 from the loading area to the security inspection area. The frame 10 moves 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 move along the first track 61 and the second track 62 respectively until the first positioning wheel 51 moves to the positioning portion of the first track 61 and the second positioning wheel 52 moves to the positioning portion of the second track 62. The first positioning wheel 51 and the second positioning wheel 52 are positioned and matched with the two positioning portions, and the frame 10 is fixed at the security inspection area.

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

[0150] According to the security inspection method of the embodiment of the present disclosure, the work of loading the workpiece 200 can be completed on the auxiliary support bracket assembly 30, and after loading, the clamping member 20 and the workpiece 200 are moved to the support roller assembly 40 as a whole, which can reduce the wear of the support roller assembly 40. Since the support roller assembly 40 is a supporting 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.
