Description

Technical Field

[0001] This application relates to the field of detection technology, specifically to a frame component and a detection device including the frame component. Background Technology

[0002] X-ray inspection technology has been widely applied in many fields. For example, inspection equipment typically consists of two main parts: an X-ray source (such as an X-ray source) and a detector. The X-ray source generates the X-rays, while the detector receives the X-rays after they pass through the object being inspected and converts them into a visual image, which can then be used to reconstruct the internal structural information of the object. Inspection equipment uses X-ray beams to irradiate objects or human bodies, and based on the scanned images, determines whether dangerous items are being carried or diagnoses diseases, making it widely used in security inspection, medical, and other fields. Inspection equipment typically includes a conveyor mechanism for transporting the object to be inspected and a channel assembly for containing the X-ray source and preventing X-ray leakage. The conveyor mechanism includes a conveyor belt, through which the object is transported by the conveyor belt and passes through the area irradiated by the X-ray source for scanning and inspection. After a period of operation, the conveyor belt may age or wear, requiring repair or replacement. This necessitates removing the old conveyor belt from the inspection equipment and replacing it with a repaired or new one. However, for existing inspection equipment, disassembling the conveyor belt is a complex process, requiring significant labor intensity and time, resulting in low efficiency in conveyor belt replacement.

Detailed Implementation

[0019] The following description provides specific details of various embodiments of this application to enable those skilled in the art to fully understand and implement the various embodiments of this application. It should be understood that the technical solutions of this application can be implemented without some of these details. In some cases, this application does not show or describe in detail some well-known structures or functions to avoid such unnecessary descriptions obscuring the description of the embodiments of this application. The terminology used in this application should be understood in its broadest and most reasonable manner, even when used in connection with specific embodiments of this application.

[0020] In particular, the meaning of "connection" and "coupling" mentioned in the embodiments of this application includes direct connection and indirect connection. Moreover, in the embodiments of this application, there are no restrictions on the specific technical means, components, number of components or materials for implementing direct connection or indirect connection. Examples of components for implementing direct connection or indirect connection include, but are not limited to, screws, adhesives and any suitable mechanical connectors.

[0021] Embodiments of this application provide a frame assembly comprising: a base, a top frame, a crossbeam assembly located between the base and the top frame, and a first support column and a second support column. Each of the first and second support columns is sequentially coupled to the base, the crossbeam assembly, and the top frame in a vertical direction. The frame assembly further includes a detachable support assembly detachably connected to both the base and the top frame. When the detachable support assembly is coupled to the base and the top frame, the first support column, the second support column, the base, the top frame, and the detachable support assembly form a receiving space. This frame assembly can be applied to inspection equipment (e.g., X-ray inspection equipment) to support and accommodate various functional components within the inspection equipment. That is, the various functional components of the inspection equipment can be installed onto the frame assembly, and the frame assembly and the various functional components form the entire inspection equipment. The detachable support assembly can be fixedly connected to the base and the top frame of the frame assembly to enhance the mechanical stability and reliability of the frame assembly, and together with the first support column, the second support column, the base, and the top frame, forms a receiving space capable of accommodating at least a portion of the functional components. When it is necessary to repair or replace parts in some functional components (e.g., conveyor belts), the operation of the functional component to be replaced or repaired can be carried out by removing the detachable support assembly. There is no need to remove the functional component to be replaced or repaired from the frame assembly before operating it. This reduces the difficulty of repairing or replacing parts in functional components (e.g., conveyor belts) and helps to improve the efficiency of replacing or repairing parts in testing equipment.

[0022] Figures 1 to 3 The figure shows a structural schematic diagram of a framework component provided according to an embodiment of this application. Figure 1 The illustration shows an example of a 3D perspective view of a frame component. Figure 2 The diagram illustrates the basis Figure 1 The front view of the frame components shown. Figure 3 The diagram illustrates the basis Figure 1 The side view of the frame component shown. Figure 1 , Figure 2 and Figure 3As shown, the frame assembly includes: a base 10, a top frame 40, a crossbeam assembly HL located between the base 10 and the top frame 40, and a first support column 20 and a second support column 30. In this example, the crossbeam assembly HL includes a rectangular structure formed by four crossbeams joined end-to-end, parallel to the base or top frame. Each of the first support column 20 and the second support column 30 is vertically coupled to the base 10, the crossbeam assembly HL, and the top frame 40 in sequence. The vertical direction mentioned here can be a direction perpendicular to the base 10, or it can deviate from this vertical direction, i.e., the vertical direction forms an angle with this vertical direction. The top frame 40 includes a rectangular assembly coupled to at least the first support column 20 and the second support column 30, the rectangular assembly connecting the first support column 20 and the second support column 30 to each other and including at least four connecting crossbeams joined end-to-end. In this example, the rectangular assembly may also include additional connectors 40a that connect two of the four connecting crossbeams that are opposite each other to each other to enhance the mechanical reliability of the top frame. In other embodiments, the top frame 40 can be a complete plate-like metal structure. This application does not impose specific limitations or requirements on the specific structure and form of the top frame; therefore, the examples described herein do not limit the possible specific structure and form of the top frame in this application. Figure 1 , Figure 2 and Figure 3 As shown, the frame assembly also includes a detachable support assembly detachably connected to the base 10 and the top frame 40, respectively. When the detachable support assembly is coupled to the base 10 and the top frame 40, the first support column 20, the second support column 30, the base 10, the top frame 40, and the detachable support assembly form a receiving space. This receiving space can be used to accommodate at least a portion of the functional components in the testing equipment. In this example, the detachable support assembly includes: a first longitudinal beam 610 and a second longitudinal beam 620 opposite to each other; a first connector 630 and a second connector 640 opposite to each other. When the detachable support assembly is connected to the base 10 and the top frame 40, the first end of the first longitudinal beam 610 and the first end of the second longitudinal beam 620 are coupled to the top frame 40 via the first connector 630, and the second end of the first longitudinal beam 610 and the second end of the second longitudinal beam 620 are coupled to the base 10 via the second connector 640.

[0023] like Figure 1 and Figure 2As shown, the first longitudinal beam 610, the second longitudinal beam 620, the first connector 630, and the second connector 640 in the detachable support assembly are coupled together to form a generally rectangular structure. The first longitudinal beam 610 and the second longitudinal beam 620 extend in a direction generally parallel to the first and second support columns. The first connector 630 and the second connector 640 extend in a plane generally parallel to the base or top frame. The first connector 630 connects the first end of the first longitudinal beam 610 and the first end of the second longitudinal beam 620, and the second connector 640 connects the second end of the first longitudinal beam 610 and the second end of the second longitudinal beam 620. The first connector 630 can be connected to the top frame 40 via screws or other fasteners, and the second connector 640 can be connected to the base 10 via screws or other fasteners. Figures 1-3 In the example shown, the second connector 640 can be connected to the base plate 70, which will be described below, via fasteners such as screws. However, the base plate 70 is not necessary, and the second connector 640 can be directly connected to the base 10 via fasteners such as screws. Therefore, in some embodiments, when it is necessary to remove the removable support assembly from the frame assembly, only the screws at the first and second connectors need to be adjusted. In some embodiments, such as Figure 1 and Figure 2 As shown, the detachable support assembly also includes a third connector 650 that is coupled to the first longitudinal beam 610 and the second longitudinal beam 620 respectively, to enhance the mechanical strength and stability of the detachable support assembly. The third connector 650 may be parallel to the first connector and the second connector.

[0024] like Figures 1-3 As shown, according to some embodiments of this application, the crossbeam assembly HL includes: a first crossbeam 510 and a second crossbeam 520 opposite to each other, and a third crossbeam 530 and a fourth crossbeam 540 opposite to each other. The two ends of the first crossbeam 510 are coupled to a first support column 20 and a second support column 30, respectively. The first crossbeam 510, the second crossbeam 520, the third crossbeam 530, and the fourth crossbeam 540 are connected end-to-end to form a rectangular structure parallel to the base or top frame. This rectangular structure can be used to carry or support functional components (e.g., conveying mechanisms) in the testing equipment. For example, the conveying mechanism can be fixedly mounted on the third crossbeam 530 and the fourth crossbeam 540, so that the detachable support assembly and the conveying mechanism will not have any potential spatial conflicts. In some embodiments, the second crossbeam 520 in the crossbeam assembly HL is detachably connected to the detachable support assembly to further enhance the overall mechanical stability of the frame assembly and more stably support and fix the functional components in the testing equipment.

[0025] According to some embodiments of this application, such as Figures 1 to 3As shown, the frame assembly also includes: a base plate 70, a third support column 80, and a fourth support column 90 located between the base 10 and the frame structure of the beam assembly HL. A first side of the base plate 70 is coupled to a first support column 20 and a second support column 30. The first ends of the third support column 80 and the fourth support column 90 are coupled to a second side of the base plate 70 opposite to the first side. The second ends of the third and fourth support columns are coupled to the base. Here, the first and second sides of the conductive base plate are referred to as... Figure 1 The base plate 70 shown is parallel to two opposing edges on the horizontal direction D1. In this embodiment, the third support column 80 and the fourth support column 90 can support the base plate 70. The detachable support assembly is detachably connected to the base plate 70. For example, the second connector 640 can be fixedly connected to the base plate 70 by fasteners such as screws. By setting the base plate 70 above the base 10, the overall size of the detachable support assembly can be reduced. In addition, the detachable support assembly is fixedly connected to the base plate at a certain distance from the base (depending on the height of the third support column 80 and the fourth support column 90), which further facilitates the operation of the detachable support assembly by the operator. The detachable support assembly can be more easily removed from the frame assembly and can also be reinstalled into the frame assembly with less effort.

[0026] like Figures 1 to 3 As shown, in some embodiments, the frame assembly further includes reinforcing ribs 101 that are respectively coupled to the first support column 20 or the second support column 30 and the top frame 40, with the extending direction of the reinforcing rib 101 forming an angle with the extending direction of the first support column 20 or the second support column 30. For example, in some embodiments, the extending direction of the reinforcing rib 101 forms an acute angle with the extending direction of the first support column 20 or the second support column 30. The reinforcing ribs can further enhance the connection stability between the top frame and the support columns, enhance the overall robustness and mechanical stability of the frame assembly, and, when the frame assembly is used in testing equipment, the reinforcing ribs can be used to fix and install some functional components in the testing equipment.

[0027] Another embodiment of this application provides a testing device that may include a frame component as described in any of the foregoing embodiments for frame components.

[0028] The following is through Figures 4 to 7 Specific examples of testing equipment.

[0029] According to some embodiments of this application, the detection device further includes a conveying mechanism mounted to the frame assembly via a beam assembly in the frame assembly. The conveying mechanism includes a conveyor belt, at least a portion of which is located within the receiving space. The conveyor belt in the conveying mechanism can carry and transport the object to be inspected through the interior of the detection device to complete the inspection of the object. Further, the detection device may also include a channel assembly for accommodating a radiation source and preventing radiation emitted from the source from leaking out. The channel assembly may include, for example, a cavity structure formed of lead material, within which the radiation source can be placed.

[0030] Figures 4 to 6 The illustration shows the conveyor mechanism and channel assembly in the testing equipment installed on the frame assembly. Figure 4 and Figure 5 These are front and side views of the overall structure of the conveyor mechanism, channel assembly, and frame assembly when they are installed onto the frame assembly. Figure 6 When the conveyor mechanism and channel assembly are installed onto the frame assembly, the overall structure of the conveyor mechanism, channel assembly, and frame assembly is parallel to... Figure 5 The side view shown is a cross-sectional view. (See example.) Figure 4 As shown, the testing equipment includes a conveying mechanism, which comprises a support frame 201 and a conveyor belt 202. The conveying mechanism can be mounted to the frame assembly via a crossbeam assembly HL in the frame assembly. For example, the support frame 201 of the conveying mechanism can be mounted and fixed to a third crossbeam 530 and a fourth crossbeam 540 in the crossbeam assembly HL, with the third crossbeam 530 and the fourth crossbeam 540 supporting and fixing the support frame 201 and other components on the support frame 201. At least a portion of the conveyor belt 202 is located in a receiving space formed by the aforementioned first support column 20, second support column 30, base 10, top frame 40, and removable support assembly. Figure 4 As shown, when the conveyor belt 202 is installed in the conveying mechanism, the length extension direction of the conveyor belt 202 is consistent with the horizontal direction D1, and the entire conveyor belt 202 extends outside the aforementioned receiving space, while the middle part of the conveyor belt is located inside the receiving space.

[0031] In some embodiments, the conveying mechanism includes a support frame and a roller assembly. The support frame is coupled to the beam assembly, and the roller assembly is rotatably mounted on the support frame. The roller assembly includes a plurality of rollers, and a conveyor belt is sequentially wound around the plurality of rollers. The plurality of rollers includes a drive roller, a redirecting roller, and a plurality of driven rollers. The drive roller and the redirecting roller are spaced apart along the conveying direction of the conveyor belt. Figure 7 A partial cross-sectional view of a conveying mechanism according to an embodiment of this application is schematically illustrated. Figure 7As shown, the conveying mechanism includes a support frame 201 and a roller assembly. The roller assembly is rotatably mounted on the support frame 201 and includes multiple rollers 2031-2036. The conveyor belt 202 is sequentially wound around the multiple rollers 2031-2036. The multiple rollers include a drive roller 2031, a redirecting roller 2032, and multiple driven rollers. The drive roller 2031 and the redirecting roller 2032 are spaced apart along the conveying direction D1 of the conveyor belt. The drive roller 2031 can be an electric roller, which can be coupled to a drive device to provide driving force for the conveyor belt. The drive roller can also be called a driving roller. The redirecting roller 2032 is actually a type of driven roller, which is spaced apart from the drive roller along the conveying direction of the conveyor belt. When the conveyor belt is wound around the redirecting roller and the drive roller, the conveyor belt forms a loop structure, thereby assisting the drive roller in driving the conveyor belt to rotate cyclically.

[0032] like Figure 7 As shown, in some embodiments, the plurality of driven rollers includes a first driven roller 2033 and a second driven roller 2034. The first driven roller 2033 is arranged on the side of the redirecting roller 2032 near the center of the conveyor belt 202, and the second driven roller 2034 is arranged on the side of the driving roller 2031 near the center of the conveyor belt 202. The connecting line between the center of the first driven roller 2033 and the center of the redirecting roller 2032, and the connecting line between the center of the second driven roller 2034 and the center of the driving roller 2031 are parallel to the conveying direction D1 of the conveyor belt 202, and the diameter of the first driven roller is smaller than the diameter of the redirecting roller, and the diameter of the second driven roller is smaller than the diameter of the driving roller. Furthermore, in some embodiments, the plurality of driven rollers further includes a third driven roller 2035 and a fourth driven roller 2036. The third driven roller 2035 and the fourth driven roller 2036 are respectively located on the side of the drive roller 2031 or the redirecting roller 2032 near the base of the frame assembly, and the distance L2 between the center of the third driven roller 2035 and the center of the fourth driven roller 2036 is greater than the distance L1 between the center of the first driven roller 2033 and the center of the second driven roller 2034. Thus, the first driven roller 2033 and the second driven roller 2034 can cooperate with the drive roller 2031 and the redirecting roller 2032 to allow the conveyor belt 202 to have a larger contact area with the drive roller 2031 and the redirecting roller 2032, which is beneficial to the smooth rotation of the conveyor belt during operation. The larger contact area between the conveyor belt and the third driven roller 2035 and the fourth driven roller 2036 allows the third driven roller 2035 and the fourth driven roller 2036 to achieve a better tensioning effect on the conveyor belt.

[0033] like Figures 4 to 6As shown, in some embodiments, the detection device further includes a channel assembly 300 located within the accommodating space formed by the aforementioned first support column, second support column, base, top frame, and detachable support components. The channel assembly 300 is coupled to the top frame 40 and the conveying mechanism (e.g., support frame 201). The channel assembly includes a detection channel, and the conveyor belt 202 includes a carrying section 202a and a return section 202b located on the side of the carrying section 202a near the base. At least a portion of the carrying section 202a is located within the detection channel. Figure 4 As shown, when the detection equipment is running to detect the object being inspected, the object being inspected is located in the carrying section 202a of the conveyor belt 202 and moves with the conveyor belt through the detection channel of the channel assembly to realize the detection of the object being inspected. The carrying section 202a and the return section 202b form a closed loop conveyor belt.

[0034] As previously described, in some embodiments, the frame assembly may include reinforcing ribs 101 respectively coupled to the first or second support column and the top frame, the extending direction of the reinforcing ribs 101 forming an angle with the extending direction of the first or second support column 20 or 30, and a channel assembly 300 respectively coupled to the reinforcing ribs 101 and the top frame 40. In some embodiments, the extending direction of the reinforcing ribs 101 forms an acute angle with the extending direction of the first or second support column 20 or 30. Thus, the channel assembly can be mounted and fixed to the frame assembly. In some embodiments, such as Figures 4 to 6 As shown, the testing equipment also includes a detachable connecting plate CL, which is detachably connected to the support frame 201 of the conveying mechanism and the channel assembly 300. When the detachable connecting plate CL connects the conveying mechanism and the channel assembly, it prevents radiation leakage from the radiation source and enhances the connection stability between the conveying mechanism and the channel assembly. Figures 4 to 6 As shown, the detachable connecting plate CL is a generally rectangular metal connecting plate that can be connected to the support frame 201 of the conveying mechanism and the channel assembly 300 by fasteners such as screws. When the detachable connecting plate CL is removed, an opening is formed between the conveying mechanism and the channel assembly.

[0035] According to some embodiments of this application, the detection device further includes an X-ray source and a detector. The X-ray source is located within the channel assembly and on the side of the detection channel near the top frame. The detector is located within the space enclosed by the carrying area of ​​the conveyor belt and the return section. For example, see... Figure 6 The X-ray source can be fixedly mounted to the top wall 300a or other side wall of the channel assembly, so that the X-ray source is located in the cavity formed by the metal wall of the channel assembly, and the detector is located in the space enclosed by the carrying area of ​​the conveyor belt and the return section, for example, Figure 7An example of the location of detector 400 is schematically illustrated. In this way, the detector can receive X-rays emitted from the X-ray source, passing through the object under inspection and the conveyor belt, to achieve imaging inspection of the object under inspection. It will be understood that in some embodiments, the inspection device may also include an outer housing to protect the components within the inspection device or enhance its aesthetic appearance; details will not be elaborated here.

[0036] The following describes the process of replacing the conveyor belt in the testing equipment described in the foregoing embodiments. The process of removing the conveyor belt from the testing equipment and installing a new conveyor belt may include the following steps: removing the aforementioned detachable support assembly from the testing equipment; disassembling the first driven roller 2033 and the second driven roller 2034 in the conveying mechanism to loosen the conveyor belt and allow it to be removed; disassembling the detachable connecting plate to form an opening between the conveying mechanism and the channel assembly; inserting the new conveyor belt through this opening into the conveying mechanism; reinstalling the first driven roller 2033 and the second driven roller 2034 into the conveying mechanism; reconnecting the detachable support assembly to the frame assembly; reconnecting the detachable connecting plate to the conveying mechanism and the channel assembly; and appropriately adjusting the position of each driven roller to ensure the conveyor belt has appropriate tension. Therefore, based on the testing equipment provided in this application embodiment, replacing the conveyor belt does not involve disassembling too many parts of the testing equipment, nor does it require disassembling the entire conveying mechanism or the entire channel assembly from the testing equipment. This achieves a more convenient and less time-consuming method for replacing the conveyor belt, improving work efficiency and reducing the maintenance cost of the testing equipment.

[0037] Figure 8 and Figure 9 The illustration shows a structural schematic diagram of a testing device according to a comparative example of this application. Figure 8 and Figure 9 These are, respectively, a side view and a front cross-sectional view of the testing equipment for a comparative example. For example... Figure 8 and Figure 9 As shown, the testing equipment includes a base frame SP, a channel assembly TS, and a conveyor mechanism TP. Both the conveyor mechanism TP and the channel assembly TS are fixedly mounted on the base frame, with the channel assembly located above the conveyor mechanism. For example, the channel assembly TS passes through at least... Figure 8 The connecting screw shown at point A is fixed to the base frame SP, and the conveying mechanism is at least through Figure 8 The connecting screw shown at point B is secured to the base frame. The base frame SP also includes a guide rail RL located below the conveyor mechanism. If the conveyor belt in the testing equipment of this comparative example is replaced, the following operations are required: disconnect the connector between the conveyor mechanism and the channel assembly; disconnect the connector between the base frame and the conveyor mechanism (e.g., Figure 8(As shown in Figure B), the connecting screws completely separate the conveyor mechanism from other components and structures of the testing equipment; allow the conveyor mechanism to fall onto the guide rail RL; use auxiliary equipment to move the conveyor mechanism away from the base frame area via the guide rail RL and to the outside of the testing equipment; perform the conveyor belt replacement operation on the conveyor mechanism from the outside of the testing equipment.

[0038] It can be seen that, compared with the testing equipment provided in the comparative examples, the testing equipment based on the frame components provided in the embodiments of this application can greatly simplify the process of replacing the conveyor belt in the conveying mechanism. The process of replacing the conveyor belt does not require removing the entire conveying mechanism or the entire channel assembly from the testing equipment, nor does it require transferring the entire conveying mechanism to the outside of the testing equipment. This achieves a convenient and time-saving way to replace the conveyor belt, thereby improving the maintenance efficiency of the testing equipment.

[0039] The foregoing has discussed some embodiments of this application, the scope of which is limited only by the appended claims. While individual features may be included in different claims, they may be advantageously combined, and the order of features in the claims does not imply that the features must operate in any particular order. Furthermore, the word "comprising" in the claims does not exclude other elements or steps.
