[0046] The present disclosure is described in detail below. In the following paragraphs, various aspects of the embodiments are defined in more detail. Each aspect defined in this manner may be combined with any other aspect or aspects unless expressly stated not to be combinable. In particular, any feature considered to be preferred or advantageous may be combined with one or more other features considered to be preferred or advantageous.

[0047] The terms "first" and "second" appearing in this disclosure are only for the convenience of description to distinguish different components with the same name, and do not indicate a priority or primary and secondary relationship.

[0048] In the description of the present disclosure, the directions or positional relationships indicated by “upper”, “lower”, “top”, “bottom”, “front”, “back”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present disclosure and do not indicate or imply that the device referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the scope of protection of the present disclosure. The origin of the coordinate system is o, the first direction x is located in the horizontal plane, and is Figure 1 The left and right directions, the second direction y is in the horizontal plane, Figure 2 The third direction z is a vertical direction and is perpendicular to the first direction x and the second direction y.

[0049] like Figures 1 to 6As shown, the present disclosure provides an inspection device, which in some embodiments includes: a radiation source 11 and an arm 2, wherein the radiation source 11 is configured to emit a radiation beam, for example, it can generate X-rays, gamma rays or neutron rays. The arm 2 includes a horizontal arm 21 and a vertical arm 22, wherein the horizontal arm 21 is arranged along a first direction x, and the radiation source 11 is arranged at the first end of the horizontal arm 21, the second end of the horizontal arm 21 is connected to the first end of the vertical arm 22, and the second end of the vertical arm 22 extends upward to form an L-shaped arm, and detectors 23 are provided on both the horizontal arm 21 and the vertical arm 22. The detector 23 is configured to receive the radiation emitted by the radiation source 11 and passing through the object to be inspected, so as to form a three-dimensional image of the surface of the object to be inspected. For example, the object to be inspected can be a container 5, a package or other container with goods inside.

[0050] An inspection channel G is formed between the radiation source 11, the horizontal arm 21, and the vertical arm 22. This channel G is configured to allow objects suspended from above to pass through, enabling scanning inspections to be achieved through the relative motion between the objects and the arm 2. The width and height of the inspection channel G can be adapted to the specifications and dimensions of commonly used objects to be inspected, for example, to the specifications and dimensions of all containers 5.

[0051] In order to achieve relative movement between the item to be inspected and the arm 2, the following methods can be used: First, the item to be inspected moves along the second direction y during the hoisting process, and the inspection equipment is fixed and remains stationary. This method can minimize the shaking of the radiation source 11 and the arm 2, ensure the accuracy of the inspection, and can be inspected while the item to be inspected is being hoisted and moved for transportation, without affecting the transportation efficiency. Moreover, when the hoisting position is high, it is easy to set up the inspection equipment in the air by fixing it, thereby improving the safety of use. Second, the item to be inspected is in a stationary state, and during the inspection process, the inspection equipment moves to cause the item to be inspected and the arm 2 to move relative to each other. Third, both the item to be inspected and the inspection equipment are in motion, but their movements are not synchronized.

[0052] This embodiment forms an upward-opening inspection channel G by arranging the horizontal arm 21 at the bottom and extending the vertical arm 22 vertically upward from the second end of the horizontal arm 21. Equipment such as slings used to lift items to be inspected can pass from above the inspection channel G. Therefore, it is suitable for realizing safety inspection during the process of lifting items to be inspected in the air, which can meet the needs of this new logistics transfer method. There is no need to unload the items to be inspected to the ground for inspection, which can improve the overall efficiency of the transfer and safety inspection of items.

[0053] In some embodiments, as Figure 1 As shown, the inspection device further includes: a support component 3 having a support surface on its top, the support surface being at a preset height from the ground, the preset height being set according to the height of the object to be inspected. The radiation source 11 and the arm 2 are disposed on the support component 3 .

[0054] This embodiment, by providing a support member 3 as the carrier of the entire imaging system, enables the radiation source 11 and the boom 2 to be positioned at a certain height to accommodate the hoisting height of the object to be inspected, thereby enabling the safety inspection of the object to be inspected while hoisted in the air. Alternatively, when the hoisting height is lower, the radiation source 11 and the boom 2 can be positioned on the ground or on a platform placed on the ground.

[0055] like Figure 1 As shown, the supporting component 3 includes: a base 31 and a supporting platform 32. The supporting platform 32 is arranged on the top of the base 31, and the top surface of the supporting platform 32 forms a supporting surface.

[0056] This embodiment uses a base 31 to support the support platform 32, so that the support platform 32 is at a certain height from the ground, and the radiation source 11 and the arm 2 are arranged on the support platform 32, which occupies a small area. It can not only realize the safety inspection of the items to be inspected in the air, but also does not affect the passage of pedestrians and vehicles, so that normal road transportation is not affected.

[0057] Specifically, a plurality of bases 31 are arranged at intervals along the second direction y to provide a more stable support force for the support platform 32. The base 31 may include a column and a support portion, which is fixed to the top of the column and gradually increases in size from bottom to top in the first direction x.

[0058] In some embodiments, as Figure 4 As shown, the installation height of the ray source 11 is not lower than the upper surface of the object to be inspected, and the horizontal rays emitted by the ray source 11 can be received by the detector 23 on the vertical arm 22.

[0059] Conventional inspection equipment has two main scanning modes: horizontal scanning and vertical scanning. Horizontal scanning places the radiation source at a lateral position of the object to be inspected, for example, on the horizontal ground or in an equipment cabin on the ground; vertical scanning places the radiation source above the object to be inspected.

[0060] With respect to the item transfer method disclosed herein, if vertical scanning is employed, it will be affected by the transfer equipment 6 above the items to be inspected, making it difficult to arrange the radiation source; if horizontal scanning is employed, it will be difficult to obtain a comprehensive image of the items to be inspected. Since the radiation emitted by the radiation source 11 is fan-shaped with a central angle a, the present disclosure arranges the radiation source 11 above and to the side of the items to be inspected, enabling the horizontal radiation emitted by the radiation source 11 to be no lower than the upper surface of the items to be inspected, and the horizontal radiation can also be received by the detector 23 on the vertical arm 22. This allows for zero-degree scanning of the items to be inspected without affecting the transportation of the hoisted items to be inspected, improving the comprehensiveness and accuracy of security inspections and facilitating layout.

[0061] In some embodiments, the inspection equipment further includes an equipment cabin 1, which includes a first cabin 1A and a second cabin 1B. The cabin 1 may be separated into the first cabin 1A and the second cabin 1B by, for example, a horizontal partition. The first cabin 1A is located on top of the second cabin 1B. The first cabin 1A is configured to accommodate a radiation source 11, and the second cabin 1B is configured to accommodate ancillary equipment of the radiation source 11, including at least one of a modulator, a water-cooling unit, and an electrical panel.

[0062] In this embodiment, the equipment compartment 1 employs a double-layer structure. The radiation source 11 is located in the top first compartment 1A, conveniently positioned above and to the side of the object to be inspected, enabling zero-degree scanning of the object. The supporting equipment for the radiation source 11 is located in the bottom second compartment 1B, facilitating inspection and maintenance. This structure allows the radiation source system to be integrated within the equipment compartment 1, reducing its footprint.

[0063] In some embodiments, as Figures 1 to 6 As shown, the inspection equipment includes two arms 2, which are respectively positioned on either side of the radiation source 11 in a first direction x. This embodiment provides two independent inspection channels G, enabling independent safety inspections of items hoisted by the transfer equipment 6 on either side of the radiation source 11, thereby improving transfer and inspection efficiency.

[0064] In some embodiments, the inspection device includes two radiation sources 11 spaced apart along a second direction y and configured to emit radiation toward the arms 2 on either side. The two arms 2 are staggered along the second direction y, wherein the second direction y is perpendicular to the first direction x in a horizontal plane. For example, the two radiation sources 11 may be located in the same equipment cabin 1, which may be located between two transfer devices 6.

[0065] For dual-channel inspection equipment, this embodiment arranges two radiation sources 11 at intervals along the second direction y, and the two radiation sources 11 work independently, which not only improves the inspection efficiency; but also arranges the two radiation sources 11 in the same equipment cabin 1, which can also reduce the space occupied by the equipment cabin 1 in the second direction y, making the layout of the inspection equipment more compact, and minimizing the space occupied by the equipment cabin 1 without affecting the operation of the items to be inspected, and realizing scanning inspection of the objects to be inspected hoisted by multiple transfer equipment 6.

[0066] like Figure 6 As shown, the inspection device further includes a protective wall 4 configured to prevent radiation from radiating outward from the protective wall 4. In the first direction x, the protective wall 4 is at least provided outside at least one of the arm 2 and the radiation source 11. For example, Figure 1 As shown, two protective walls 4 are provided and installed on the supporting platform 32 , and the two protective walls 4 are respectively located on the outside of the arms 2 on both sides.

[0067] This embodiment can prevent the radiation emitted by the radiation source 11 from radiating outward from the protective wall 4, thereby improving the safety of personnel and other equipment at work.

[0068] In such Figures 7 to 10 ,as well as Figure 11 In the embodiment shown, the inspection device includes a single arm 2, which is provided on one side of the radiation source 11 along the first direction x. Accordingly, one radiation source 11 is also provided.

[0069] This embodiment can realize single-channel inspection and is suitable for situations where the items to be inspected are hoisted and passed along a single fixed path. The arm 2 can be fixed on one side of the radiation source 11, or the arm 2 can be detachably arranged so as to be selectively arranged on the side where the items to be inspected are hoisted according to the needs of the scanning inspection.

[0070] During the scanning process of the article security inspection system disclosed herein, the radiation source 11 and the detectors 23 on the horizontal arm 21 and the vertical arm 22 remain relatively stationary, and the container 5 moves along the second direction y driven by the transfer equipment 6. When the container 5 passes through the inspection channel G, the radiation source 11 emits X-rays, which penetrate the container 5. The detectors 23 located on the horizontal arm 21 and the vertical arm 22 receive the X-rays and convert them into output signals, generating digital image signals in real time to achieve security inspection of the container 5.

[0071] Secondly, the present disclosure provides an article transfer inspection system. In some embodiments, such as Figures 1 to 5 As shown, it comprises: a transfer device 6 and the inspection device of the above embodiment. The transfer device 6 is configured to hoist the items to be inspected; the inspection device is configured to perform safety inspection on the items to be inspected passing through the inspection channel G.

[0072] The inspection equipment in this embodiment forms an inspection channel G with an upward opening, and equipment such as slings used to lift the items to be inspected can pass from above the inspection channel G. Therefore, by using this inspection equipment in conjunction with the transfer equipment 6, safety inspections can be carried out during the aerial lifting of the items to be inspected, which can meet the needs of this new logistics transfer method. There is no need to unload the items to be inspected to the ground for inspection, which can improve the overall efficiency of the transfer and safety inspection of the items.

[0073] To achieve relative movement between the object to be inspected and the arm 2, the transfer device is configured to move the object to be inspected along the second direction y during the hoisting process, while the inspection device is fixed and remains stationary. This method can minimize vibration of the radiation source 11 and the arm 2, ensuring the accuracy of the inspection. The inspection can be carried out while the object to be inspected is being hoisted and moved for transport, without affecting the efficiency of the transport. Moreover, when the hoisting position is high, the fixed inspection device also facilitates its installation at high altitude, improving its safety.

[0074] Optionally, the object to be inspected is in a stationary state, and during the inspection process, the inspection device moves so that the object to be inspected moves relative to the arm 2. Alternatively, both the object to be inspected and the inspection device are in motion, but their movements are not synchronized.

[0075] In some embodiments, as Figure 3 As shown, the transfer device 6 includes a track 61, a lifting device, and a drive unit. The track 61 extends along the second direction y and is located between the radiation source 11 and the vertical arm 22 in the first direction x, where the second direction y is perpendicular to the first direction x. The lifting device is configured to lift the object to be inspected, such as a hook. The drive unit is configured to drive the lifting device to move the object to be inspected along the track 61.

[0076] This embodiment can move the items to be inspected along the track 61 through the driving components during the hoisting process, and can perform safety inspections during the hoisting and transportation process, thereby improving the efficiency of transportation and safety inspections of the items.

[0077] In some embodiments, as Figure 3 As shown, the article transfer inspection system includes two transfer devices 6, each of which includes two arms 2. In a first direction x, the two transfer devices 6 are located on either side of a radiation source 11, and the two arms 2 are located on either side of the radiation source 11. This embodiment enables independent security inspections during the transfer of articles via the two transfer devices 6, improving inspection efficiency through dual-channel inspections.

[0078] like Figure 5 As shown, the article transfer inspection system also includes a fixed bracket 7, which includes a support column 71, two extension arms 72 and two connecting parts 73. The bottom end of the support column 71 is fixed to the ground, and the two extension arms 72 are connected to the top of the support column 71 and extend to both sides along the first direction x. The extension arms 72 and the support column 71 can be connected by an inclined portion. The two connecting parts 73 are respectively connected to the outer ends of the two extension arms 72 and extend downward. The two connecting parts 73 are configured to be fixed to the two rails 61 respectively. In order to reliably fix the rails 61, two fixed brackets 7 are provided, which are respectively located on both sides of the equipment cabin 1 along the second direction y. In order to avoid the extension arm 72, a notch 41 can be set on both sides of the top of the protective wall 4.

[0079] In other embodiments, Figures 7 to 10 As shown, Figures 1 to 6 The difference between the embodiments is that the article transfer inspection system includes two transfer devices 6, the inspection device includes a single arm 2, and in the first direction x, the two transfer devices 6 are respectively located on both sides of the radiation source 11, and the arm 2 can be optionally arranged on any side of the radiation source 11.

[0080] This embodiment provides two transfer devices 6 and allows the arm 2 to be selectively positioned on either side of the radiation source 11. This simplifies the structure of the article transfer inspection system and reduces costs when the articles to be inspected are hoisted and passed along a single fixed path. Furthermore, the arm 2 can be installed on the desired side based on the requirements of the hoisting inspection, providing flexibility to meet transfer inspection needs.

[0081] like Figure 9 As shown, two protective walls 4 are respectively arranged on the outside of the arm 2 and the outside of the equipment cabin 1, which can prevent the rays emitted by the ray source 11 from radiating outward from the protective walls 4, thereby improving the safety of personnel and other equipment.

[0082] In some further embodiments, Figure 11 As shown, Figures 7 to 10 The illustrated embodiment differs in that the article transfer inspection system includes a single transfer device 6, and the inspection device includes a single boom 2. In the first direction x, the transfer device 6 and boom 2 are located on the same side of the radiation source 11. This embodiment is suitable for situations where articles to be inspected are hoisted and passed along a single fixed path, and features a simple structure and cost savings.

[0083] In this embodiment, two protective walls 4 are also arranged on the outside of the arm 2 and the outside of the equipment cabin 1 respectively, which can prevent the rays emitted by the radiation source 11 from radiating outward from the protective walls 4, thereby improving the safety of personnel and other equipment.

[0084] The above is a detailed introduction to the inspection equipment and article transfer inspection system provided by the present disclosure. Specific embodiments are used herein to illustrate the principles and implementation methods of the present disclosure. The description of the above embodiments is only intended to help understand the method and core concept of the present disclosure. It should be noted that for ordinary technicians in this technical field, without departing from the principles of the present disclosure, several improvements and modifications can be made to the present disclosure, and these improvements and modifications also fall within the scope of protection of the claims of the present disclosure.
