Description

Technical Field

[0001] This disclosure relates to the field of radiation inspection technology, and more specifically, to a CT device. Background Technology

[0002] CT technology plays a vital role in security inspections because it can eliminate the effects of overlapping objects. CT equipment is also widely used in technical fields such as item inspection; it can inspect not only smaller items such as baggage and flight cases, but also larger items such as containers and vehicles.

[0003] In related technologies, existing traditional CT equipment uses a single large bearing to support the rotatable part. The entire CT imaging system is mounted on this single large bearing and driven to rotate by a motor and multi-ribbed belts. For this type of CT equipment, the imaging system lacks a transport locking mechanism. However, with the emergence of distributed bearing CT equipment, a demand has arisen for a transport locking mechanism for the imaging system. Distributed bearing CT equipment relies on a lower support roller assembly to support the imaging system, which is a semi-open structure. During transportation, this inevitably results in significant impact on the support roller assembly, potentially causing damage.

[0035] The following is combined Figures 1A to 4B The CT device according to the embodiments of this disclosure will be described in detail.

[0036] Figure 1A This is a front view of a CT device according to some exemplary embodiments of the present disclosure. Figure 1B This is a side view of a CT device according to some exemplary embodiments of the present disclosure.

[0037] like Figure 1A and Figure 1B As shown, the CT equipment 100 includes: a frame 110, a support device 1, a rotatable part 2, a scanning device 3, and a transport locking mechanism 4.

[0038] The frame 110 is used to support the CT equipment 100, and the support device 1 is disposed on the frame 110 to support the rotatable part 2. For example, the support device 1 may be disposed on a first side and a second side of the frame 110 near the lower side.

[0039] The support device 1 includes a plurality of rotatable wheels 11, wherein at least one rotatable wheel 11 of the support device 1 serves as a drive wheel.

[0040] The rotatable part 2 can rotate around the rotation axis AX1 under the drive of the drive wheel of the support device 1. During the rotation of the rotatable part 2, the rotatable part 2 is supported by the support device 1. For example, the rotatable part 2 is... Figure 1A The rotatable part 2 is supported by the support device 1 and driven by the drive wheel. When the rotatable part 2 rotates, the other rotatable wheels 11 support the rotatable part 2.

[0041] Figure 2A This is a side view of a rotatable portion of a CT device according to some exemplary embodiments of the present disclosure. Figure 2B This is a front view of a rotatable portion of a CT device according to some exemplary embodiments of the present disclosure.

[0042] like Figure 2A and Figure 2BAs shown, the scanning device 3 includes a radiation source 31 and a detector 32. Both the radiation source 31 and the detector 32 are mounted on the rotatable part 2 and are arranged opposite each other along the radial direction of the rotatable part 2. For example, if the radiation source 31 is located at a first position on the periphery of the rotatable part 2 and the detector 32 is located at a second position opposite to the first position on the periphery, it can be ensured that no vibration or minimal vibration occurs when the rotatable part 2 rotates the radiation source 31 and the detector 32.

[0043] In embodiments of this disclosure, such as Figure 1B as well as Figure 2A and Figure 2B As shown, the support device 1 restricts the movement of the rotatable part 2 in the radial direction. The rotatable part 2 includes a rotatable body 22 and at least one rotatable track 21. The scanning device 3 is disposed on the rotatable body 22.

[0044] In embodiments of this disclosure, such as Figure 1A As shown, the CT device 100 also includes a transport locking mechanism 4, which is used to control and maintain the gap between the rotatable part 2 and the support device 1 to prevent the rotatable part 2 from impacting the support device 1 during the transport of the CT device 100.

[0045] In some embodiments of this disclosure, the transport locking mechanism 4 is located below the rotatable body 22 to support it. Furthermore, the transport locking mechanism 4 is located within the receiving space formed by the two rotatable tracks 21 and the rotatable body 22. Specifically, the rotatable part 2 includes the rotatable tracks 21 and the rotatable body 22, and has a relatively large weight; moreover, the rotatable part 2 is equipped with a radiation source 31 and a detector 32, making its overall weight relatively large. During the transport of the CT equipment, due to vibration, bumps, or tilting, the rotatable part 2 placed directly on the support device 1 will cause a significant impact on the support device 1, potentially even leading to damage. Introducing the transport locking mechanism 4 detaches the rotatable part 2 from the support device 1, distributing the weight and impact force of the rotatable part 2 to the transport locking mechanism 4, thereby preventing the rotatable part 2 from impacting the support device 1.

[0046] In embodiments of this disclosure, the CT device 100 includes at least one transport locking mechanism 4.

[0047] In some embodiments of this disclosure, such as Figure 1A and Figure 1BAs shown, the CT device 100 may include two transport locking mechanisms 4, which are arranged on both sides of the rotatable body 22 along the circumferential direction. It is understood that by providing two transport locking mechanisms, which lock the two sides of the rotatable part 2 respectively, torque balance during locking can be better achieved, avoiding uneven force distribution or the inability to effectively maintain the gap between the rotatable part and the support device.

[0048] like Figure 1A and 1B As shown, the upward direction D1 and the downward direction D2 of the rotatable part 2 are perpendicular to the rotation axis AX1, and the upward direction D1 and the downward direction D2 are opposite.

[0049] Figure 3A This is a front view of a transport locking mechanism of a CT device according to some exemplary embodiments of the present disclosure. Figure 3B This is a side view of a transport locking mechanism of a CT device according to some exemplary embodiments of the present disclosure. Figure 3C This is a front view of a lifting device for a CT device according to some exemplary embodiments of the present disclosure.

[0050] In some embodiments of this disclosure, such as Figure 3A and Figure 3B As shown, the transport locking mechanism 4 includes a first support part 411, a second support part 412, and a connecting part 413 for connecting the first support part 411 and the second support part 412. The first support part 411 is used to contact and support the rotatable body 22, and the second support part 412 is used to connect the frame 110.

[0051] For example, the first support part 411, the second support part 412 and the connecting part 413 can be fabricated using rectangular tubes and steel plates, and then the first support part 411, the second support part 412 and the connecting part 413 can be welded together. The structure is simple, easy to process and has high compressive strength.

[0052] In some embodiments of this disclosure, such as Figure 1A As shown, the CT equipment 100 also includes a lifting device 5, which is located on the frame 110. The lifting device 5 is used to lift the rotatable part 2 and is configured to lift the rotatable part 2 upward so that the rotatable part 2 is disengaged from the support of the support device 1.

[0053] For example, the lifting device 5 can be a type of... Figure 3CThe device shown is a lifting device 5 mounted on a frame 110. It can lift the rotatable part 2 and move it in the upward direction D1, causing the rotatable part 2 to disengage from the support device 1. Specifically, the lifting device 5 may include a mounting block 51, a support part 52, two connecting rod assemblies 53, and a drive assembly 54. The drive assembly 54 drives the two connecting rod assemblies 53 to open and close synchronously, thereby raising and lowering the support part 52.

[0054] like Figure 3C As shown, the support part 52 includes a support plate 521 and a roller assembly 522. The length direction of the support plate 521 is perpendicular to the rotation axis AX1, and the support plate 521 is curved on the side near the rotatable part 2. The roller assembly 522 is located on the side of the support plate 521 near the rotatable part 2. The roller assembly 522 includes a first roller and a second roller, which are respectively located on both sides of the support plate 521 along its length. The first roller and the second roller are symmetrically arranged about the center of the rotatable part 2. The rollers are rotatably mounted on the support plate 521 and their rotation axis is parallel to the rotation axis AX1. When the lifting device 5 lifts the rotatable part 2 upward, the rollers abut against the rotatable track 21.

[0055] like Figure 3C As shown, each connecting rod assembly 53 includes a first connecting rod 531 and a second connecting rod 532. The first end of the first connecting rod 531 is hinged to the frame 110, and the hinge axis is parallel to the rotation axis AX1. The second end of the first connecting rod 531 is hinged to the first end of the second connecting rod 532, and the hinge axis is parallel to the rotation axis AX1. The support plate 521 is hinged to the mounting block 51, and the hinge axis is parallel to the rotation axis AX1. The second end of the second connecting rod 532 is hinged to the mounting block 51, and the hinge axis is parallel to the rotation axis AX1. The hinge point between the support plate 521 and the mounting block 51 is collinear with the center of the rotatable part 2.

[0056] like Figure 3CAs shown, the drive assembly 54 includes a lead screw 541, two sliders 542, and a drive member 543. The lead screw 541 is arranged perpendicular to the rotation axis AX1. The two sliders 542 are the first slider and the second slider, respectively, dividing the two connecting rod groups 53 into a first connecting rod group and a second connecting rod group. The first connecting rod group is located on the first side of the frame 110, and the second connecting rod group is located on the second side of the frame 110. The first connecting rod group and the second connecting rod group are symmetrically arranged about the center of the rotatable part 2. The first slider corresponds to the first connecting rod group, and the second slider corresponds to the second connecting rod group. In the first connecting rod group, the second end of the first connecting rod and the first end of the second connecting rod are both hinged to the first slider; in the second connecting rod group, the second end of the first connecting rod and the first end of the second connecting rod are both hinged to the second slider; the first slider and the second slider are both threaded onto the lead screw 541. The drive member 543 is a servo motor, and the output end of the servo motor is fixedly connected to one end of the lead screw 541. A servo motor drives the lead screw 541 to rotate, so that multiple connecting rod groups 53 open and close synchronously.

[0057] Please continue reading. Figure 3C The working principle of the lifting device 5 described above will now be explained. It can be understood that when the rotatable part 2 needs to be lifted, the servo motor is activated, driving the lead screw 541 to rotate. This causes the first and second sliders on the lead screw 541 to move closer together, increasing the opening angle between the first connecting rod 531 and the second connecting rod 532 in each connecting rod group 53. Since the first end of the first connecting rod 531 is fixed, the second end of the second connecting rod 532 moves in the upward direction D1, thereby lifting the rotatable part 2 and achieving the lifting of the rotatable part 2. Conversely, when the support device 1 is needed to support the rotatable part 2, the servo motor is started, and the servo motor drives the lead screw 541 to rotate, thereby causing the first slider and the second slider on the lead screw 541 to move away from each other, so that the opening angle between the first connecting rod 531 and the second connecting rod 532 in each connecting rod group 53 becomes smaller. Since the first end of the first connecting rod 531 is fixed, the second end of the second connecting rod 532 moves in the downward direction D2, thereby causing the rotatable part 2 to descend and be placed on the support device 1.

[0058] It should be noted that the number of lifting devices 5 is not specifically limited in this embodiment, and can be set according to the actual application. For example, the lifting devices 5 can be set to one, two, or three sets, etc.

[0059] In some embodiments of this disclosure, such as Figure 1AAs shown, the lifting device 5 is located below at least one rotatable track 21, and the transport locking mechanism 4 and the lifting device 5 are spaced apart in the extension direction of the rotation axis AX1. After the rotatable part 2 is lifted off the support device 1 by the lifting device 5, the first support part 411, the second support part 412, and the connecting part 413 are placed between the rotatable body 22 and the frame 110. Exemplarily, the first support part 411 and the rotatable body 22 can be connected together with high-strength bolts, and the second support part 412 and the frame 110 can be connected together with high-strength bolts to ensure that the positions of the rotatable body 22 and the frame 110 are relatively fixed.

[0060] According to embodiments of this disclosure, the spaced-apart lifting device and transport locking mechanism effectively separate the rotatable part from the support device and maintain the gap, preventing the rotatable part from impacting the support device during transportation and causing damage to the wheel assembly. This helps extend the service life of the CT equipment. Furthermore, the transport locking mechanism can be welded from rectangular tubing and steel plates, resulting in a simple structure, low manufacturing difficulty and cost, and high reliability.

[0061] Figure 4A This is a front view of the transport locking mechanism of a CT device according to some other exemplary embodiments of this disclosure. Figure 4B yes Figure 4A Side view of a CT scanner.

[0062] In other embodiments of this disclosure, such as Figure 4A and 4B As shown, the transport locking mechanism 4 may include a lifting device 5', which is used to lift the rotatable part 2. The lifting device 5' is configured to lift the rotatable part 2 upward, so that the rotatable part 2 is detached from the support of the support device 1. It should be noted that the lifting device 5' in the transport locking mechanism 4 and the lifting device 5 independently configured in the CT equipment 100 have the same function, both being used to lift the rotatable part upward, so that the rotatable part is detached from the support of the support device. The main difference between the two lies in their configuration positions. Due to the different configuration positions, the lifting devices 5 and 5' lift the rotatable part 2 at different locations, and the lifting mechanisms required are also different.

[0063] For example, the lifting device 5' may include a jack, which may be driven manually or electrically, and may be transmitted by hydraulic transmission or screw transmission, so as to conveniently realize the lifting action.

[0064] Please continue reading. Figure 4AThe transport locking mechanism 4 may further include a movable frame 421, a fixed frame 422, and a shim assembly 423. The movable frame 421 connects to and supports the rotatable body 22, and is configured to rise or fall simultaneously with the rotatable part 2 when the lifting device 5' lifts or lowers it. The fixed frame 422 connects to the frame 110. The shim assembly 423 maintains and controls the gap between the movable frame 421 and the fixed frame 422, thereby maintaining and controlling the gap between the rotatable part 2 and the support device 1.

[0065] In some embodiments of this disclosure, such as Figure 4A As shown, the movable frame 421 includes a first movable frame support, a second movable frame support, and a movable frame connecting part for connecting the first movable frame support and the second movable frame support. The first movable frame support is used to contact and support the rotatable body 22, and the second movable frame support is used to contact the pad assembly 423.

[0066] For example, the first movable frame support, the second movable frame support, and the movable frame connecting part can be fabricated using rectangular tubes and steel plates respectively, and then welded into a whole movable frame 421.

[0067] In some embodiments of this disclosure, such as Figure 4A As shown, the mounting bracket 422 includes a first mounting bracket support, a second mounting bracket support, and a mounting bracket connecting part for connecting the first mounting bracket support and the second mounting bracket support. The first mounting bracket support is used to contact and support the pad assembly 423, and the second mounting bracket support is used to connect the frame 110.

[0068] For example, the first fixed frame support, the second fixed frame support, and the connecting part can be fabricated using rectangular tubes and steel plates and then welded into a single fixed frame 422.

[0069] In some embodiments of this disclosure, such as Figure 4A As shown, the gasket assembly 423 includes multiple gasket assembly units, the first end face of the gasket assembly unit contacts and supports the second movable frame support, and the second end face of the gasket assembly unit contacts the first fixed frame support.

[0070] In some embodiments of this disclosure, such as Figure 4A As shown, multiple gasket units are spaced apart in the gap between the movable frame 421 and the fixed frame 422. For example, they can be evenly arranged in the gap between the movable frame 421 and the fixed frame 422 to ensure uniform force distribution at each support.

[0071] For example, the gasket assembly unit can be made of high-strength steel, which has strong compressive strength.

[0072] According to embodiments of this disclosure, the transport locking mechanism, which includes a lifting device, not only effectively separates the rotatable part from the supporting device and maintains the gap, preventing the rotatable part from impacting the supporting device during transport and causing damage to the wheel assembly, but also offers ease of use and simple operation. Furthermore, the transport locking mechanism can be manufactured by welding rectangular tubing and steel plates, resulting in a simple structure, low manufacturing difficulty and cost, and high reliability.
