[0002] The present disclosure relates to the technical field of detection equipment, and in particular to an inspection equipment. Background Art

[0003] CT equipment uses X-ray beams to illuminate objects or human bodies, and determines whether they are carrying dangerous items or diagnoses diseases based on the scanned images. CT equipment is widely used in security and medical fields.

[0004] CT equipment usually includes multiple components. In related technologies, multiple components are usually installed on a supporting pallet. The weight of each component is different, and different sections of the supporting pallet bear different loads. The CT equipment is placed on the ground, and the supporting pallet is in direct contact with the ground, and the loads borne by different areas of the supporting pallet cannot be detected. The pressure on different areas of the ground in contact with the supporting pallet is uneven, and the areas of the ground with greater force may be at risk of collapse or cracking, which in turn affects the reliable operation of the CT equipment. In addition, the supporting pallet is deformed due to uneven force, which will cause changes in the gaps between the components and the height of the components, causing the inspection channel to deform and affecting the operation of the equipment.

DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions, and advantages of the present disclosure more clearly understood, the present disclosure is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It is apparent that the embodiments described are only a portion of the embodiments of the present disclosure, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present disclosure without inventive effort are intended to fall within the scope of protection of the present disclosure.

[0033] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise," "include," etc. used herein indicate the presence of the features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0034] In the description of this disclosure, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on the specific circumstances.

[0035] The inspection equipment provided according to the embodiment of the present disclosure can at least achieve the following technical effects: an installation area is constructed inside the supporting frame, the inspection device is installed in the installation area of ​​the supporting frame, and one or more detection mechanisms are provided at the bottom of the supporting frame. The detection mechanisms are used to detect the pressure values ​​at corresponding positions of the supporting frame. Based on the pressure values, it is convenient to take timely measures for areas of the supporting frame where the force is greater, so that the overall force of the supporting frame is balanced, thereby avoiding damage to the ground in contact with the inspection equipment and ensuring the reliable operation of the inspection equipment.

[0036] The inspection device according to the embodiment of the present disclosure will be described below with reference to FIG. 1 to FIG. 8 .

[0037] As shown in Figure 1, the inspection equipment provided by the embodiment of the present disclosure includes a supporting frame 1, an inspection device 2 and a pressure detection unit; the inspection device 2 is installed inside the supporting frame 1, and the inspection device 2 is configured to emit radiation rays to the object to be inspected to obtain a scanned image of the object to be inspected; the pressure detection unit is connected to the supporting frame 1, wherein the pressure detection unit includes N detection mechanisms 3, and the N detection mechanisms 3 are used to detect the pressure values ​​applied by the supporting frame 1 at N positions, where N is an integer greater than or equal to 1.

[0038] Specifically, the inspection equipment disclosed herein is used to inspect objects or human bodies. The inspection device 2 includes at least one ray scanning component 23, which can emit radiation rays to the object to be inspected to scan the object to be inspected, obtain a scanned image of the object to be inspected, and diagnose and identify the object to be inspected based on the scanned image.

[0039] The inspection device 2 also includes shielding components located on both sides of the ray scanning component 23. The two shielding components are defined as a first shielding component 21 and a second shielding component 22. The first shielding component 21 has a channel entrance connected to the outside, and a first shielding curtain is installed at the channel entrance. The second shielding component 22 has a channel exit connected to the outside, and the second shielding curtain is installed at the channel exit. The ray scanning component 23 has a scanning channel, the first shielding component 21 has a first channel, and the second shielding component 22 has a second channel. The first channel, the scanning channel and the second channel are connected to each other to form an inspection channel 24.

[0040] The first shielding curtain opens, and the object to be inspected enters the inspection channel from the channel entrance. The first and second shielding curtains close, and the radiation scanning component 23 emits radiation toward the object to be inspected for inspection. The first and second shielding components 21 and 22 shield the radiation from the inspection radiation and the area outside the inspection device 2. After the inspection of the object is complete, the second shielding curtain opens, and the object to be inspected leaves the inspection device 2 through the channel exit.

[0041] The supporting frame 1 is used to support the inspection device 2. It is formed by splicing together multiple horizontal beams and multiple longitudinal beams. The supporting frame 1 can be a single, integrated frame or composed of multiple frames. For example, the supporting frame 1 can be composed of three frames, corresponding to the first shielding component 21, the second shielding component 22, and the radiation scanning component 23, respectively. These three frames are defined as the first frame 11, the second frame 12, and the third frame 13. The first frame 11 and the third frame 13 can be connected by welding, screwing, or clamping, while the second frame 12 and the third frame 13 can be connected by welding, screwing, or clamping.

[0042] As will be understood, a conveyor assembly is mounted at a predetermined height from the bottom of the support frame 1. The conveyor assembly extends through the first shielding member 21, the second shielding member 22, and the radiation scanning member 23, and is used to transport the object to be inspected. The conveyor assembly can be a belt drive or a roller drive. A storage space is formed between the conveyor assembly and the bottom of the support frame 1. This space is used to house auxiliary components of the inspection equipment, including fans, control systems, and electrical equipment.

[0043] The weight of the radiation scanning component 23 is greater than the weight of the first shielding component 21 and the weight of the second shielding component 22. Different parts of the supporting frame 1 bear different weights, with the central section of the supporting frame 1 bearing greater weight than the weights on the sides of the supporting frame 1. If the inspection equipment is placed on the ground and the bottom surface of the supporting frame 1 is in direct contact with the ground, the different weights of the various components of the inspection device 2 will cause uneven pressure on the ground. This is especially true for floors with load-bearing requirements, such as the second floor and above, or the first floor with a basement.

[0044] The inspection equipment is placed on the ground with load requirements, and the load-bearing frame 1 is in direct contact with the ground. Since different sections of the load-bearing frame 1 bear different loads, local positions of the load-bearing frame 1 bear too much load, which will cause local areas of the ground to be over-pressurized, and then collapse or crack. The ground is damaged, which further affects the relative position relationship between the various components of the inspection device 2. For example, the ray scanning component 23 sinks and the first shielding component 21 and the second shielding component 22 rises, affecting the transportation of the conveying component and the inspection of the inspection device 2, resulting in the inspection equipment not being able to operate normally.

[0045] A pressure detection unit is provided at the bottom of the supporting frame 1. This unit includes N detection mechanisms 3, which are spaced apart across the bottom of the supporting frame 1. Along the width of the supporting frame 1, the supporting frame 1 has a first side and a second side that oppose each other. Along the length of the supporting frame 1, the detection mechanisms 3 are spaced apart at the bottom of the first side, and at the bottom of the second side. The detection mechanisms 3 are used to detect pressure at corresponding locations on the supporting frame 1 and include pressure testers.

[0046] The inspection equipment is placed on the ground. Multiple detection mechanisms 3 at the bottom of the support frame 1 detect pressure values ​​at various locations on the support frame 1. The pressure values ​​detected by the detection mechanisms 3 are defined as real-time pressure values. For example, if the real-time pressure value detected by the detection mechanism 3 at the third frame 13 corresponding to the radiation scanning component 23 is greater than the standard value, it indicates that the pressure on the third frame 13 is relatively high. To address this situation, the accessory components placed in the accommodation space of the third frame 13 can be placed outside the third frame 13, or the accessory components placed in the accommodation space of the third frame 13 can be placed in the accommodation spaces corresponding to the first frame 11 and the second frame 12.

[0047] The pressure values ​​at multiple positions of the supporting frame 1 are detected by the detection mechanism 3. When the real-time pressure value at a certain position is greater than the standard value, timely measures can be taken to ensure that the multiple positions of the supporting frame 1 reach a state of force balance, thereby avoiding damage to the ground and ensuring the reliable operation of the inspection equipment.

[0048] In the embodiment of the present disclosure, an installation area is constructed inside the supporting frame 1, and the inspection device 2 is installed in the installation area of ​​the supporting frame 1. A plurality of detection mechanisms 3 are provided at the bottom of the supporting frame 1. The plurality of detection mechanisms 3 are used to detect the pressure values ​​at multiple positions of the supporting frame 1. Based on the pressure values, it is convenient to take timely measures for the areas of the supporting frame 1 where the force is uneven, so that the supporting frame 1 as a whole is in a state of balanced force, thereby avoiding damage to the ground in contact with the inspection equipment and ensuring the reliable operation of the inspection equipment.

[0049] In some embodiments, for example, the pressure detection unit is located above the supporting frame 1. Specifically, the detection mechanism is a tensile detection member, such as a tensile rod, connected to the top of the supporting frame. The tensile data of the tensile rod can be monitored and directly converted into a pressure signal to determine the pressure value. The tensile data can be obtained by monitoring the deformation of the tensile rod.

[0050] As shown in Figures 2 and 3, in other embodiments, for example, the pressure detection part is located at the bottom of the supporting frame 1, the detection mechanism 3 includes a supporting mechanism 31 and a pressure sensor 32, and the supporting mechanism 31 is configured to support the supporting frame 1 thereon; the pressure sensor 32 is connected to the bottom of the supporting frame 1 and the supporting mechanism 31, and is located between the bottom of the supporting frame 1 and the supporting mechanism 31.

[0051] Specifically, the inspection mechanism 3 includes a support mechanism 31 and a pressure sensor 32. The pressure sensor 32 can be mounted to the bottom surface of the support frame 1 via fasteners. The support mechanism 31 has a first end and a second end that are opposite each other. The first end of the support mechanism 31 is connected to the pressure sensor 32, and the second end of the support mechanism 31 is configured to contact the ground. It will be appreciated that the second end of the support mechanism 31 is a planar structure, providing an appropriate contact area with the ground to ensure stable placement of the inspection device.

[0052] Pressure sensor 32 is mounted on the bottom of support frame 1. One end of support mechanism 31 is connected to pressure sensor 32, while the other end of support mechanism 31 is in contact with the ground. This mounting position of pressure sensor 32 allows for accurate detection of real-time pressure at corresponding locations on support frame 1 while preventing damage from direct contact with the ground. The space created between the multiple support mechanisms 31 and the bottom surface of support frame 1 facilitates the transport of inspection equipment.

[0053] As shown in Figures 2 and 3, in an optional embodiment, support mechanism 31 includes a base 312 and an adjustment rod 311. Base 312 rests against the ground. Adjustment rod 311 is connected to pressure sensor 32 at one end and to base 312 at the other end. Adjustment rod 311 is configured to change the distance between the bottom of support frame 1 and the ground. In some embodiments, by changing this distance, the pressure value detected by at least one pressure sensor 32 is adjusted, thereby achieving uniform load distribution.

[0054] Specifically, the support mechanism 31 includes a base 312 and an adjustment rod 311. The adjustment rod 311 can be an adjustment screw with a threaded section extending from one end of the adjustment rod 311 to the other end; alternatively, the adjustment rod 311 can have a threaded section at one end; alternatively, the adjustment rod 311 can have a smooth middle section and threaded sections at both ends. One end of the adjustment rod 311 is connected to the pressure sensor 32, and the other end of the adjustment rod 311 is connected to the base 312. The cross-section of the base 312 can be circular or square, and has a suitable thickness and cross-sectional dimensions.

[0055] For example, one end of the adjustment rod 311 is threadedly connected to the pressure sensor 32, and the other end of the adjustment rod 311 is fixedly connected to the base 312. By screwing the adjustment rod 311 in or out, the overall height of the support mechanism 31 is adjusted, thereby adjusting the distance between the bottom of the supporting frame 1 and the ground. For example, one end of the adjustment rod 311 is fixedly connected to the pressure sensor 32, and the other end of the adjustment rod 311 is threadedly connected to the base 312. By screwing the base 312 in a clockwise or counterclockwise direction, the overall height of the support mechanism 31 is adjusted, thereby adjusting the distance between the bottom of the supporting frame 1 and the ground.

[0056] Alternatively, one end of the adjusting rod 311 is threadedly connected to the pressure sensor 32, and the other end of the adjusting rod 311 is threadedly connected to the base 312. By screwing the adjusting rod 311 in or out, the overall height of the support mechanism 31 is adjusted to adjust the distance between the bottom of the supporting frame 1 and the ground.

[0057] If the real-time pressure value detected by the pressure sensor 32 at a certain position is greater than the standard value, the overall height of the support mechanism 31 can be lowered by screwing the adjustment rod 311 or the base 312 to reduce the pressure on the supporting frame 1 at that position.

[0058] In some embodiments, the adjustment rod 311 may also be a telescopic rod, a sleeve rod, or other structures.

[0059] During the process of adjusting the supporting frame 1, the supporting mechanism 31 can be raised as a whole where the real-time pressure value detected by the pressure sensor 32 is less than the standard value, or the supporting mechanism 31 can be lowered as a whole where the real-time pressure value detected by the pressure sensor 32 is greater than the standard value, so as to achieve a state in which the multiple real-time pressure values ​​detected by multiple pressure sensors 32 are consistent, thereby ensuring that the supporting frame 1 as a whole is in a state of balanced force.

[0060] During the adjustment process, for the multiple real-time pressure values ​​detected by the multiple pressure sensors 32, it is preferred to lower the support mechanism 31 as a whole at the position where the real-time pressure value is larger. During the height adjustment process, it is easier to operate by lowering the support mechanism 31 as a whole.

[0061] It should be understood that the present disclosure is not limited to adjusting the pressure value by changing the distance between the bottom of the support frame and the ground. For example, if the pressure value obtained by a certain detection mechanism deviates from the standard value, the pressure value can be adjusted by assembling or disassembling components above the detection mechanism. Alternatively, a lifting mechanism can be added to apply an upward pulling force to the support frame to adjust the pressure value.

[0062] In the embodiment of the present disclosure, one end of the adjusting rod 311 is connected to the pressure sensor 32, and the other end of the adjusting rod 311 is connected to the base 312, and the base 312 is in contact with the ground. By screwing the adjusting rod 311 or the base 312, the supporting mechanism 31 is raised or lowered as a whole to increase or decrease the pressure on the supporting frame 1 at the position corresponding to the detection mechanism 3, which is conducive to convenient and flexible adjustment of the pressure on different positions of the supporting frame 1.

[0063] In an optional embodiment, the pressure at each position has a corresponding standard value, and the inspection equipment also includes a data acquisition device and a control device. The data acquisition device is communicatively connected to the N pressure sensors 32 and is used to collect N pressure values ​​detected by the N pressure sensors 32; the control device is communicatively connected to the data acquisition device, and when any pressure value deviates from its standard value, the control device is used to control the adjustment rod 311 to change the distance until the error between the pressure value and its standard value is less than or equal to the preset value.

[0064] Specifically, a data acquisition device is communicatively connected to multiple pressure sensors 32. The data acquisition device can collect the pressure value detected by any pressure sensor 32 and define the pressure value detected by the pressure sensor 32 as a real-time pressure value. The pressure experienced by the corresponding area of ​​the support frame 1 corresponding to each pressure sensor 32 has a standard value. A control device is communicatively connected to the data acquisition device and controls the rotation parameters of the adjustment rod 311 based on the real-time pressure value collected by the data acquisition device, thereby achieving precise adjustment of the overall height of the support mechanism 31.

[0065] For example, the real-time pressure value detected by the pressure sensor 32 at a certain position of the supporting frame 1 is greater than the standard value. The control device controls the adjustment rod 311 to rotate forward according to the real-time pressure value collected by the data acquisition device, thereby reducing the overall height of the support mechanism 31 until the error between the real-time pressure value detected by the pressure sensor 32 and the standard value is less than or equal to the preset value, and the adjustment rod 311 stops rotating.

[0066] For example, if the real-time pressure value detected by the pressure sensor 32 at a certain position of the supporting frame 1 is smaller than the standard value, the control device controls the adjustment rod 311 to rotate out according to the real-time pressure value collected by the data acquisition device, thereby increasing the overall height of the support mechanism 31 until the error between the real-time pressure value detected by the pressure sensor 32 and the standard value is smaller than or equal to the preset value, and the adjustment rod 311 stops rotating.

[0067] In the embodiment of the present disclosure, if the real-time pressure value detected by any pressure sensor 32 deviates from the standard value, the control device adjusts the overall height of the support mechanism 31 corresponding to the pressure sensor 32 based on the real-time pressure value collected by the data acquisition device, and can quickly adjust the pressure at multiple positions of the supporting frame 1 in real time to ensure the reliable operation of the inspection equipment.

[0068] As shown in Figures 4, 5 and 6, in an optional embodiment, the supporting frame 1 includes S vertical beams and T connecting beams, the S vertical beams are used to support and transfer the load of the inspection device 2, and S is greater than or equal to N; wherein each connecting beam is connected to a vertical beam at both ends to support and transfer the load of the inspection device 2, and T is greater than or equal to 1; wherein the orthographic projections of the N detection mechanisms 3 are one-to-one corresponding to or close to the orthographic projections of the N vertical beams.

[0069] Specifically, the supporting frame 1 includes S vertical beams and T connecting beams. The number of vertical beams and connecting beams can be multiple, and the number of vertical beams and connecting beams can be set according to actual needs. The supporting frame 1 includes a first frame 11, a second frame 12, and a third frame 13, which correspond one-to-one with the first shielding component 21, the second shielding component 22, and the radiation scanning component 23.

[0070] For example, the first frame 11 is composed of four first vertical beams 111 and a plurality of first connecting beams 112, forming a square frame structure. The four first vertical beams 111 and the plurality of first connecting beams 112 enclose a first installation area for mounting the first shielding component 21. The second frame 12 is composed of four second vertical beams 121 and a plurality of second connecting beams 122, forming a square frame structure. The four second vertical beams 121 and the plurality of second connecting beams 122 enclose a second installation area for mounting the second shielding component 22.

[0071] The third frame 13 is composed of four third vertical beams 131 and a plurality of third connecting beams 132. The four third vertical beams 131 and the plurality of third connecting beams 132 enclose a third mounting area for mounting the radiation scanning component 23. It is understood that the connection between the third frame 13 and the first frame 11 can share the same vertical beam, and the connection between the third frame 13 and the second frame 12 can also share the same vertical beam.

[0072] Taking the third frame 13 as an example, two third vertical beams 131 are spaced apart on the first side of the radiation scanning component 23. The bottoms of the two third vertical beams 131 are connected by a third connecting beam 132, and the tops of the two third vertical beams 131 are connected by a third connecting beam 132. The multiple third vertical beams 131 and the multiple third connecting beams 132 support and transmit the load of the radiation scanning component 23.

[0073] The detection mechanism 3 is mounted on the bottom surface of the third connecting beam 132 at the bottom of the third frame 13, and the detection mechanism 3 corresponds to the position of the third vertical beam 131, or the detection mechanism 3 is close to the third vertical beam 131. The load borne by the third frame 13 is transmitted to the detection mechanism 3 by the third vertical beam 131, and further transmitted to the ground by the detection mechanism 3. The real-time pressure value detected by the detection mechanism 3 is used to adjust the load at the corresponding position, so that the load borne by the third frame 13 is evenly distributed, thereby reducing deformation of the inspection channel 24.

[0074] The arrangement of the detection mechanism 3 on the first frame 11 and the second frame 12 is similar to that on the third frame 13 and will not be further described. It will be appreciated that the end of the first frame 11 near the third frame 13, and the end of the first connecting beam 112 near the third connecting beam 132, only need to be provided with the support mechanism 31, and no pressure sensor 32 is required.
