Description

Technical Field

[0001] This application belongs to the field of detection technology, specifically relating to a detection device. Background Technology

[0002] In numerous testing fields, such as medical diagnostics, industrial flaw detection, and security inspection, testing devices play a crucial role. Among these, testing devices, such as DR (Digital Radiography) testing devices, typically include a radiation source that emits specific types of radiation, such as X-rays. These rays can penetrate the human body or objects, and by receiving and analyzing the information from the penetrating radiation, precise detection of the interior of the human body or objects can be achieved.

[0003] In related technologies, radiation sources are generally installed by fixing them to the frame of the detection device. When maintenance or repair of the detection device is required, especially when maintenance or repair of the radiation source itself is involved, the radiation source needs to be removed from the frame. However, due to the large weight of the radiation source, the friction between the radiation source and the frame is large when the radiation source moves relative to the frame, making disassembly and assembly difficult. Moreover, it usually requires multiple maintenance personnel to work together, which increases labor costs. Utility Model Content

[0004] The purpose of this application is to provide a detection device that can solve the problems of high difficulty and high cost in disassembling and assembling X-ray sources in related technologies.

[0005] This application provides a detection device, which includes a frame and a radiation generating module. The frame is provided with a pre-positioning position and an installation position, and the radiation generating module can move between the pre-positioning position and the installation position. At least one of the frame and the ray generating module is provided with a rolling element, and when the ray generating module moves between the pre-positioned position and the installation position, the ray generating module slides with the frame through the rolling element.

[0006] In this embodiment, since at least one of the radiation generating module and the frame is provided with a rolling element, when the radiation generating module moves between the pre-positioned position and the installation position, the radiation generating module can slide with the frame through the rolling element. With this configuration, when installing the radiation generating module, that is, when installing the radiation generating module from the pre-positioned position to the installation position, and when disassembling the radiation generating module, that is, when moving the radiation generating module from the installation position to the pre-positioned position, the friction between the radiation generating module and the frame can be transformed into rolling friction through the rolling element. This can effectively reduce the friction between the radiation generating module and the frame, so that maintenance personnel do not need to apply a lot of force to push or pull the radiation generating module when disassembling or assembling it. This can save the physical strength of maintenance personnel, make it easier for a single maintenance personnel to complete the disassembly and assembly work, reduce labor costs, and reduce the difficulty of disassembling and assembling the radiation generating module. Meanwhile, by setting rolling elements, wear between the X-ray generating module and the frame can be reduced, and the stability of the X-ray generating module during movement can be improved. This can reduce collisions and scratches between the X-ray generating module and other parts of the detection device, thereby extending the service life of the detection device and reducing safety risks.

Detailed Implementation

[0009] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0010] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0011] The detection device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0012] refer to Figures 1-5 The detection device provided in this application embodiment may include a skeleton 100 and a radiation generating module 200. The skeleton 100 may be provided with a pre-positioning position and an installation position. The radiation generating module 200 may be moved between the pre-positioning position and the installation position to realize the assembly and disassembly of the radiation generating module 200.

[0013] At least one of the skeleton 100 and the X-ray generating module 200 may be provided with a rolling element 300, and when the X-ray generating module 200 moves between the pre-positioned position and the installation position, the X-ray generating module 200 can slide with the skeleton 100 through the rolling element 300.

[0014] In this embodiment, the detection device can be, for example, a security inspection machine. The detection device also includes components such as a detection channel, a radiation detection module, and a shielding assembly, all of which can be implemented with reference to the implementation principles of relevant components in existing detection devices. When the item being detected moves in the detection channel, the radiation generating module 200 and the radiation detection module can cooperate to scan and detect the item. The shielding assembly can be used to shield the radiation to prevent leakage from the detection device.

[0015] The frame 100 refers to the structural component that can provide support and a mounting base for the X-ray generating module 200. Taking a security inspection machine as an example, the X-ray generating module 200 is mounted on the frame 100. The X-ray source in the X-ray generating module 200 can be in the form of a top X-ray source (top source) of the security inspection machine or a bottom X-ray source (bottom source) of the security inspection machine.

[0016] It should be noted that the pre-placement position refers to the position where the frame 100 first contacts the radiation generating module 200 during the installation process. Specifically, the pre-placement position can be the location of the pre-suspension groove described below. The installation position of the radiation generating module 200 refers to the position where the radiation generating module 200 is installed.

[0017] With this configuration, during the installation of the X-ray generating module 200 (i.e., when installing the X-ray generating module 200 from the pre-positioned position to the installation position) and during the disassembly of the X-ray generating module 200 (i.e., when moving the X-ray generating module 200 from the installation position to the pre-positioned position), the rolling element 300 can change the friction between the X-ray generating module 200 and the frame 100 from static friction to rolling friction. This effectively reduces the frictional force between the X-ray generating module 200 and the frame 100, allowing maintenance personnel to push or pull the X-ray generating module 200 without applying a lot of force. This saves the physical strength of maintenance personnel and makes it easier for a single maintenance worker to complete the disassembly and assembly work, thus reducing the difficulty of disassembling and assembling the X-ray generating module 200. Meanwhile, by setting the rolling element 300, the wear between the X-ray generating module 200 and the frame 100 can be reduced, and the stability of the X-ray generating module 200 during movement can be improved. This can reduce collisions and scratches between the X-ray generating module 200 and other parts of the detection device, thereby extending the service life of the detection device and reducing safety risks.

[0018] In this embodiment, the rolling element 300 may include a roller.

[0019] In alternative implementations, such as Figure 1 , Figure 2 and Figure 5As shown, the X-ray generating module 200 may be equipped with a handle 400, which protrudes from the frame 100 along the direction from the installation position to the pre-positioning position. This allows the handle 400 to protrude from the frame 100 after the X-ray generating module 200 is installed in place. This design allows the operator to grip the handle 400 to push or pull the X-ray generating module 200 during installation and removal, eliminating the need for tools to drag or pull it, thus facilitating operation. Furthermore, because the handle 400 protrudes along the direction from the installation position to the pre-positioning position, it facilitates the operator in applying force along this direction.

[0020] In other embodiments, the radiation generating module 200 may not have a handle 400. Maintenance personnel can directly apply force to the radiation generating module 200, or they can use other tools to push or pull the radiation generating module 200, such as using ropes to tie the radiation generating module 200 and pulling the ropes to pull the radiation generating module 200.

[0021] In alternative implementations, such as Figure 2 As shown, the radiation generating module 200 may include a radiation source 210 and a radiation source mounting base 220. The radiation source 210 may be mounted on the radiation source mounting base 220, and the radiation source mounting base 220 may be provided with a rolling element 300. The radiation source mounting base 220 can slide with the frame 100 through the rolling element 300. In this embodiment, the rolling element 300 is mounted on the radiation source mounting base 220 (for example, it can be mounted on the bottom or side of the radiation source mounting base 220). Compared with the method of directly mounting the rolling element 300 on the radiation source 210, this can further avoid modifying the structure of the radiation source 210, and thus is less likely to affect the internal components of the radiation source 210, thereby ensuring the service life and operational stability of the radiation source 210.

[0022] In other embodiments, the radiation generating module 200 may also include only the radiation source 210, on which a rolling element 300 is provided (for example, it may be provided at the bottom or side of the radiation source), and the radiation source 210 is slidably connected to the frame 100 through the rolling element 300.

[0023] In this embodiment, as Figure 1As shown, the X-ray source mounting base 220 can be provided with a mounting groove 221, and the X-ray source 210 can be installed in the mounting groove 221. For example, the X-ray source 210 can be provided with a threaded hole, and the X-ray source mounting base 220 can be provided with a fixing screw 224. The fixing screw 224 connects to the threaded hole to fix the X-ray source 210 to the X-ray source mounting base 220. Here, the threaded hole can be provided on the bottom wall 1131 of the X-ray source 210, and the fixing screw 224 can pass through the bottom wall 1131 of the X-ray source mounting base 220 and extend into the mounting groove 221 for connection with the X-ray source 210. Optionally, the X-ray source 210 can be provided with multiple threaded holes, and the X-ray source mounting base 220 can be provided with multiple fixing screws 224, with each threaded hole corresponding to each fixing screw 224. This improves the connection stability between the X-ray source 210 and the X-ray source mounting base 220.

[0024] Optionally, such as Figure 1 and Figure 2 As shown, the handle 400 mentioned above can be mounted on the radiation source mounting base 220. In this way, when assembling or disassembling the radiation generating module 200, no force needs to be applied to the radiation source 210, thus making it less likely to damage the radiation source 210.

[0025] In some embodiments, the X-ray source holder 220 can be formed by bending sheet metal. This eliminates the need for mold making, resulting in lower processing costs for the X-ray source holder 220.

[0026] In alternative implementations, such as Figure 1 , Figure 2 and Figure 4As shown, the X-ray generating module 200 may be equipped with a rolling element 300, and the frame 100 may be equipped with a sliding groove 113. The sliding groove 113 may have a bottom wall 1131 that slides in cooperation with the rolling element 300, and the bottom wall 1131 is inclined downward along the direction a from the pre-positioned position to the installation position. In this embodiment, since the bottom wall 1131 of the sliding groove 113 is inclined downward along the direction a from the pre-positioned position to the installation position, when installing the X-ray generating module 200, it is only necessary to align the rolling element 300 of the X-ray generating module 200 with the inlet of the sliding groove 113, and the X-ray generating module 200 will slide into the frame 100 along the bottom wall 1131 of the sliding groove 113 under its own gravity. In this way, the external force required during installation can be effectively reduced, the installation difficulty can be reduced, and the installation efficiency can be improved. Meanwhile, the inclined design of the bottom wall 1131 of the slide 113 causes the X-ray generating module 200 to experience a resistance from the pre-placed position to the installation position within the frame 100. When the detection device is subjected to external forces such as vibration or impact during normal use, this resistance can prevent the X-ray generating module 200 from sliding outward along the slide 113, thereby effectively preventing the X-ray generating module 200 from accidentally detaching from the frame 100, thus ensuring the stability and reliability of the X-ray generating module 200 installation. In addition, the sliding engagement between the rolling element 300 and the slide 113 means that the rolling element 300 does not need to occupy the installation space within the frame 100, thereby effectively increasing the installation space inside the frame 100.

[0027] In other embodiments, the bottom wall 1131 of the slide 113 may not be inclined downward in the direction a from the pre-positioned position to the installation position.

[0028] In some implementations, such as Figure 3 As shown, the frame 100 may include a mounting frame, a first side plate 111, and a second side plate 112. Both the first side plate 111 and the second side plate 112 are connected to the mounting frame, and a mounting cavity 110 for mounting the radiation generating module 200 can be formed between the first side plate 111, the second side plate 112, and the mounting frame. Here, the first side plate 111 can form the first cavity wall of the mounting cavity 110, and the second side plate 112 can form the second cavity wall of the mounting cavity 110.

[0029] Optionally, such as Figure 3As shown, the first side plate 111 and the second side plate 112 are spaced apart along the first direction b, and both the first side plate 111 and the second side plate 112 can be provided with sliding grooves 113. Rolling elements 300 can be provided on both sides of the X-ray generating module 200 along the first direction b. Specifically, rolling elements 300 can be provided on both sides of the X-ray source fixing base 220 along the first direction b, and each rolling element 300 can slide and engage with each sliding groove 113. With this arrangement, the bottom walls 1131 of both sliding grooves 113 can support the X-ray generating module 200, ensuring that the force on both sides of the X-ray generating module 200 is the same during sliding, thus ensuring the stability of the X-ray generating module 200 during sliding. Simultaneously, the bottom walls 1131 of both sliding grooves 113 can guide the X-ray generating module 200, ensuring that the X-ray generating module 200 is not easily deviated during sliding. Here, the first direction b intersects with the direction a from the pre-positioned position to the installation position and also intersects with the vertical direction.

[0030] In alternative implementations, such as Figure 3 As shown, the skeleton 100 can also be provided with a slot 114, which can communicate with the slide 113 and can be located on the side of the slide 113 away from the pre-placement position. When the X-ray generating module 200 is in the installation position, the rolling element 300 is located in the slot 114. With this configuration, when the X-ray generating module 200 is installed in place, the rolling element 300 is in a suspended state and no longer contacts the bottom wall 1131 of the slide 113, thus making it less likely to roll. This prevents rolling friction between the X-ray generating module 200 and the skeleton 100, making it less likely for the X-ray generating module 200 to shake or shift.

[0031] In other embodiments, the empty slot 114 may not be provided on the skeleton 100.

[0032] Optionally, such as Figure 3 As shown, slots 114 can be provided on both the first side plate 111 and the second side plate 112.

[0033] Further optional, such as Figure 3 As shown, a transition plane 119 can be provided between the empty groove 114 and the bottom wall 1131 of the slide 113, allowing the rolling element 300 to roll along the transition plane 119. With this configuration, when the disassembly ray generating module 200 is activated, the rolling element 300 moves from the area of ​​the empty groove 114 towards the bottom wall 1131 of the slide 113. The transition plane 119 reduces the height difference between the empty groove 114 and the bottom wall 1131 of the slide 113, making the rolling process of the rolling element 300 smoother and preventing it from jamming due to sudden height changes, thereby reducing the difficulty of disassembly.

[0034] Of course, a transition plane may not be provided between the bottom wall 1131 of the empty groove 114 and the sliding groove 113.

[0035] In some implementations, such as Figure 3 As shown, a limiting part 118 can also be provided on the skeleton 100. The limiting part 118 is located on the side of the slide groove 113 away from the pre-placement position, and in the direction a from the pre-placement position to the installation position, the limiting part 118 cooperates with the rolling element 300 for limiting. With this configuration, the limiting part 118 can limit the rolling element 300, thereby keeping the X-ray generating module 200 in the installation position so that the X-ray generating module 200 is installed in place.

[0036] It should be noted that when the rolling element 300 comes into contact with the limiting part 118, it indicates that the X-ray generating module 200 is installed in place.

[0037] In alternative implementations, such as Figure 3 As shown, the frame 100 can also be provided with a pre-suspension groove 115, which can communicate with the slide groove 113. The pre-suspension groove 115 can be set at a pre-positioning position, and the rolling element 300 can slide into the pre-suspension groove 115. With this configuration, when the X-ray generating module 200 is disassembled or assembled, the pre-suspension groove 115 can play a pre-fixing role for the X-ray generating module 200, thereby facilitating the installation or removal of the X-ray generating module 200 by maintenance personnel and reducing the difficulty of disassembling and assembling the X-ray generating module 200.

[0038] Of course, the pre-suspension groove 115 may not be provided on the frame 100.

[0039] In some embodiments, the mounting frame can be formed by welding square tubing, and the first side plate 111, the second side plate 112, the support plate 116 (described below), the slide 113, the slot 114, and the pre-suspension groove 115 can be formed by bending and welding sheet metal. This eliminates the need for mold making, thereby reducing processing costs.

[0040] In alternative implementations, such as Figure 2 and Figure 5As shown, the detection device may further include an adjusting member 500. When the radiation generating module 200 is in the installation position, the adjusting member 500 can be connected to both the radiation generating module 200 and the frame 100, and can be used to adjust the position of the radiation generating module 200 in the first direction b. With this configuration, when the radiation generating module 200 is installed on the frame 100, if the radiation generating module 200 is not fully aligned with the radiation detection module of the detection device, the adjusting member 500 can adjust the position of the radiation generating module 200 in the first direction b to align it with the radiation detection module, thereby achieving a better working position for the radiation generating module 200, obtaining a better radiation emission angle and coverage area, and thus improving the accuracy of the detection results.

[0041] Here, the first direction b intersects with the direction a from the pre-position to the installation position and also intersects with the vertical direction. For example, the first direction b can be perpendicular to the movement direction of the ray generating module 200 and also perpendicular to the vertical direction.

[0042] In this embodiment, the X-ray detection module can be disposed on the frame 100 and can be opposite to the X-ray generating module 200. A detection channel for the passage of an object can be formed between the X-ray detection module and the X-ray generating module 200, so that the X-rays emitted by the X-ray generating module 200 can pass through the object and irradiate the X-ray detection module, thereby realizing the detection of the object.

[0043] In other embodiments, the detection device may not include the adjustment element 500.

[0044] Optionally, such as Figure 1 , Figure 2 and Figure 5 As shown, the ray generating module 200 may be provided with a first connecting part 223, such as... Figure 3 and Figure 5 As shown, a second connecting portion 117 can be provided on the frame 100. When the radiation generating module 200 is in the installation position, the first connecting portion 223 and the second connecting portion 117 are opposite each other. The adjusting member 500 can be connected to the first connecting portion 223 and the second connecting portion 117 respectively, and can be used to adjust the distance between the first connecting portion 223 and the second connecting portion 117 in the first direction b, so as to adjust the position of the radiation generating module 200 in the first direction b. With this configuration, by providing the first connecting portion 223 on the radiation generating module 200 and the second connecting portion 117 on the frame 100, it is convenient to provide installation space for the adjusting member 500 and provide ample operating space for maintenance personnel, so as to facilitate their operation.

[0045] Of course, the first connecting part 223 may not be provided on the X-ray generating module 200, and the second connecting part 117 may not be provided on the frame 100. When the X-ray generating module 200 is in the installation position, the X-ray generating module 200 may be directly connected to the frame 100.

[0046] Optionally, such as Figure 3 As shown, the second connecting portion 117 can protrude upward from the second side plate 112. This arrangement allows the adjusting component 500 to be exposed outside the frame 100, providing ample operating space for maintenance personnel. When adjusting the position of the radiation generating module 200 in the first direction b, maintenance personnel do not need to insert their hands or tools into the frame 100, avoiding operational inconvenience caused by limited space. This allows for easier and more accurate rotation, twisting, or sliding of the adjusting component 500, improving adjustment efficiency and precision.

[0047] In some embodiments, the first connecting portion 223 may be provided with a connecting hole, such as Figure 3 As shown, the second connecting part 117 is provided with a connecting groove 1171, and the opening of the connecting groove 1171 can be oriented towards the pre-placed position. The adjusting member 500 can be an adjusting bolt, and the first connecting part 223 can be provided with a fixing nut. The fixing nut can be positioned opposite to the connecting hole. The screw of the adjusting bolt can pass through the connecting groove 1171 and the connecting hole and be connected to the fixing nut. By rotating the adjusting bolt, the distance between the first connecting part 223 and the second connecting part 117 in the first direction b can be adjusted, thereby adjusting the position of the X-ray generating module 200 in the first direction b. Of course, the first connecting part 223 may not be provided with a fixing nut, and the connecting hole can be a threaded hole, and the adjusting bolt can be threadedly connected to the connecting hole. Here, in the first direction b, the second connecting part 117 and the head of the adjusting bolt are in a limiting fit, that is, the diameter of the head of the adjusting bolt is larger than the size of the connecting groove 1171, so that the adjusting bolt can be connected to the second connecting part 117.

[0048] Optionally, such as Figure 5 As shown, in the direction a from the pre-placement position to the installation position, the groove wall of the connecting through groove 1171 is matched with the adjusting member 500 to limit the second connecting part 117 so that the radiation generating module 200 can be limited, thereby ensuring that the radiation generating module 200 is installed in place.

[0049] In alternative implementations, such as Figure 5As shown, the detection device may also include a fixing member 600. When the X-ray generating module 200 is in the installation position, the X-ray generating module 200 and the frame 100 can be connected through the fixing member 600. This configuration allows the X-ray generating module 200 to be securely fixed to the frame 100 via the fixing member 600, thereby effectively resisting vibration, impact, etc., preventing displacement or loosening of the X-ray generating module 200, and ensuring that the X-ray generating module 200 is always in a stable working position.

[0050] In other embodiments, the detection device may not include the fastener 600, that is, when the radiation generating module 200 is in the installation position, the radiation generating module 200 may not be fixedly connected to the frame 100.

[0051] Optionally, such as Figures 3-5 As shown, a support plate 116 can be provided on the frame 100, such as... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a fixing plate 222 can be provided on the X-ray generating module 200. When the X-ray generating module 200 is in the installation position, the fixing plate 222 is placed on the support plate 116 and can be fixedly connected to the support plate 116 by the fastener 600. In this embodiment, the fixing plate 222 can distribute part of the weight of the X-ray generating module 200 to the support plate 116, and then the support plate 116 transfers it to the frame 100. This can prevent the weight of the X-ray generating module 200 from acting on the rolling element 300, which would cause the rolling element 300 to be damaged due to excessive force. This helps to extend the service life of the rolling element 300. It can also prevent the frame 100 or the X-ray generating module 200 from having local stress concentration and deformation problems, thereby helping to extend the service life of the detection device. Meanwhile, by connecting the fixing plate 222 and the support plate 116 through the fastener 600, it is no longer necessary to set the connection holes of the fastener 600 on the radiation generating module 200 and the frame 100, which helps to improve the structural strength of the radiation generating module 200 and the frame 100.

[0052] In this embodiment, the fixing plate 222 may be provided with a first fixing hole, such as... Figure 3 As shown, a second fixing hole 1161 can be provided on the support plate 116. When the X-ray generating module 200 is in the installation position, the first fixing hole and the second fixing hole 1161 are aligned in the vertical direction. The fixing member 600 can pass through the first fixing hole and connect to the second fixing hole 1161 to realize the connection between the fixing plate 222 and the support plate 116. Here, the fixing member 600 can be connected with screws.

[0053] Of course, the support plate 116 may not be provided on the skeleton 100, and the fixing plate 222 may not be provided on the radiation generating module 200. When the radiation generating module 200 is in the installation position, the radiation generating module 200 and the skeleton 100 can be directly connected by screws or the like.

[0054] In some embodiments, support plates 116 can be provided on both the first side plate 111 and the second side plate 112, and fixing plates 222 can be provided on both sides of the radiation generating module 200 in the first direction b. Specifically, fixing plates 222 are provided on both sides of the radiation source fixing base 220 in the first direction b, and each fixing plate 222 is respectively mounted on the corresponding support plate 116. This arrangement can ensure the force balance between the radiation generating module 200 and the frame 100. Furthermore, each fixing plate 222 is connected to the corresponding support plate 116 by at least two fasteners 600. This arrangement can further improve the connection strength and stability between the radiation generating module 200 and the frame 100.

[0055] In this embodiment, when the X-ray source 210 needs maintenance, the fixing member 600 can be removed first, and then the handle 400 can be pulled to move the entire X-ray generating module 200 from the installation position to the pre-placement position. After moving a certain distance, the rolling member 300 contacts the bottom wall 1131 of the slide groove 113. The handle 400 can be pulled to move the rolling member 300 along the bottom wall 1131 of the slide groove 113 to the pre-placement position until the entire X-ray generating module 200 is detached from the frame 100.

[0056] When installing the X-ray source 210, the X-ray source 210 can be installed into the fixing groove 221 of the X-ray source fixing base 220, so that the X-ray source 210 and the X-ray source fixing base 220 are integrated into one unit, that is, forming the X-ray generating module 200. Then, the X-ray generating module 200 is lifted to the pre-placement position by the handle 400, and the rolling element 300 is embedded into the pre-suspending groove 115. Then, the X-ray generating module 200 is slowly pushed by the handle 400 until the rolling element 300 contacts the bottom wall 1131 of the slide groove 113. Under the action of the thrust and the gravity of the X-ray generating module 200 itself, the X-ray generating module 200 can slide along the bottom wall 1131 of the slide groove 113 until the rolling element 300 moves into the empty groove 114, indicating that the X-ray generating module 200 is installed in place. Finally, the fixing plate 222 of the X-ray source fixing base 220 and the support plate 116 on the frame 100 are connected by the fixing element 600.

[0057] It should be noted that when the radiation source in the radiation generation module 200 is the top radiation source of the detection device, the bottom of the fixing groove 221 of the radiation source fixing seat 220 can be provided with an opening so that the radiation emitted by the radiation source 210 can pass through and thus irradiate the detection item.
