Description

Technical Field

[0001] This utility model relates to the field of cultural relic scanning equipment, and in particular to a vertical all-round CT scanning imaging device for cultural relics. Background Technology

[0002] Cultural relics (especially metalware, ceramics, lacquerware, and funerary objects) are mostly fragile, non-renewable, and "one-time" relics. Traditional methods of dismantling, cutting, and sampling can cause irreversible damage. CT scans can penetrate the surface of cultural relics and directly reveal internal details. The core value of CT scanning imaging of cultural relics lies in solving the pain points of "invisibility, inability to disassemble, and reluctance to move" in traditional cultural relic research and protection in a "non-destructive, precise, and comprehensive" way. It provides key support for the historical interpretation, scientific protection, and digital inheritance of cultural relics. Furthermore, cultural relics will gradually deteriorate due to natural aging and environmental changes, while the digital data generated by CT scans can serve as a "permanent backup." For example, the "mold core" (casting residue) inside bronzes, the filling material inside the abdominal cavity of terracotta figurines (such as the grain residue in Han Dynasty terracotta figurines), and the interlayer inside scrolls of calligraphy and painting (such as the patching paper used in ancient restorations) can be clearly identified without dismantling.

[0003] Existing CT scanners for scanning cultural relics typically feature height-adjustable sample stages that can be flexibly positioned within the scanning chamber to facilitate loading and unloading and ensure precise alignment between the relic and the X-ray source, thus improving portability during the inspection process. However, due to the inherent weight of artifacts such as bronzes and clay sculptures, the impact of the descending sample stage, especially if the relic is irregularly shaped, can easily cause it to sway or shift, affecting its stability and, given its fragile nature, compromising its safety. Utility Model Content

[0004] To address the aforementioned issues, this application provides a vertical omnidirectional CT scanning imaging device for cultural relics.

[0005] To achieve the above objectives, this application provides the following technical solution: a vertical omnidirectional CT scanning imaging device for cultural relics, comprising a cabin, wherein relatively distributed X-ray sources and detectors are provided inside the cabin, a platform that can be raised and lowered is provided between the X-ray sources and detectors, a support plate that can be raised and lowered synchronously is provided below the platform, and a movable seat arranged parallel to it is provided below the support plate.

[0006] Multiple limiting rods are fixed at the top of the movable seat, and multiple sliding rods are fixed at the bottom of the support plate. Multiple alignment sleeves are fixed at the bottom of each sliding rod. The sliding rods and alignment sleeves are sleeved on the outside of the limiting rods. A shock-absorbing component is provided on the outside and lower part of the limiting rods. When the platform and support plate descend, the sliding rods and alignment sleeves approach the shock-absorbing component until the alignment sleeves are in contact with the shock-absorbing component.

[0007] Furthermore, each of the shock-absorbing components includes a pad fixed to the top of the movable seat. The top of each pad is connected to a docking ring via a pressure spring. The top of each docking ring is fixedly connected to a shock-absorbing sleeve. The pad, pressure spring, docking ring, and shock-absorbing sleeve all surround the outside of the limiting rod and are coaxially distributed with the limiting rod.

[0008] The inner side of the shock-absorbing sleeve has an inverted frustum-shaped accommodating space. As the sliding rod descends, the alignment sleeve descends to the inner side of the shock-absorbing sleeve and abuts against the inclined wall of the inner side of the shock-absorbing sleeve.

[0009] Furthermore, two parallel linkage racks are fixed at the bottom of the support plate, and the same electric gear set is meshed on one side of each of the two linkage racks. The electric gear set is fixed to the movable seat through a mounting bracket.

[0010] Furthermore, a driver is provided below the support plate, and the output end of the driver is installed through the central axis of the support plate and the stage. When the driver is running, the stage rotates in the relative space between the radiation source and the detector.

[0011] Furthermore, a first slider is fixed to the bottom of the movable seat, and a Y-axis linear module adapted to it is installed on the first slider. When the Y-axis linear module is running, the first slider, the movable seat, the support plate and the platform move synchronously along the Y-axis direction.

[0012] Furthermore, a second slider is fixed to the bottom of the Y-axis linear module, and an X-axis linear module adapted to it is installed on the second slider. The X-axis linear module is fixed inside the cabin. When the X-axis linear module is in operation, the second slider, the Y-axis linear module, the first slider, and the moving seat move synchronously along the X-axis direction.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] When the platform and support plate of this invention descend, the sliding rod fixed to the support plate descends synchronously. The alignment sleeve located at the bottom of the sliding rod can connect with the shock-absorbing component. The shock-absorbing component can prevent the platform and the cultural relics it carries from shaking, thereby effectively preventing irregularly shaped cultural relics from shaking on the platform surface, ensuring the stability of the cultural relics and providing a protective effect.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Reference Figure 1 , Figure 2 and Figure 6The illustrated vertical omnidirectional CT scanning imaging device for cultural relics includes a chamber 1. Inside the chamber 1 are relatively distributed X-ray sources 2 and detectors 3. A movable platform 4 is positioned between the X-ray sources 2 and detectors 3. During the CT scanning imaging operation, the X-ray sources 2 and detectors 3 remain stationary. The platform 4 rotates the cultural relic 360° around its central axis (perpendicular to the X-ray axis), ensuring that the X-rays penetrate the sample from different angles. The detectors 3 simultaneously acquire projection data from each angle. To maintain the stability of the platform 4, a support plate 5 is provided below the platform 4, which can be raised and lowered synchronously. Below the support plate 5, a movable seat 6 is arranged parallel to it. The movable seat 6 can move the support plate 5 and the platform 4 within the chamber 1 to adjust their positions.

[0025] Before performing the CT scan, the support plate 5 and stage 4 move to the hatch of chamber 1 to receive the artifact placed by the staff. After the artifact is placed, the support plate 5 and stage 4, carrying the artifact, move again to the space between the radiation source 2 and detector 3 for the CT scan. During the movement of the support plate 5 and stage 4 to the hatch of chamber 1, they must be lowered to avoid the radiation source 2 and to stably receive the artifact to be scanned. When the support plate 5 and stage 4, carrying the artifact, move again to the space between the radiation source 2 and detector 3, they must move to a designated height to ensure accurate reception of the radiation emitted from the radiation source 2. After the artifact scanning is completed, the above steps are repeated to remove the scanned artifact and place the next artifact to be scanned.

[0026] like Figure 3 , Figure 5 As shown, multiple limiting rods 61 are fixed to the top of the movable seat 6, and multiple sliding rods 51 are fixed to the bottom of the support plate 5. Multiple alignment sleeves 52 are fixed to the bottom of each sliding rod 51. The sliding rods 51 and alignment sleeves 52 are fitted onto the outside of the limiting rods 61. A shock-absorbing component is located on the outside and lower part of the limiting rods 61. When the platform 4 and support plate 5 descend, the sliding rods 51 and alignment sleeves 52 approach the shock-absorbing component until the alignment sleeves 52 come into contact with it. Therefore, when the support plate 5, platform 4, and the artifact after scanning descend, the contact between the alignment sleeves 52 and the shock-absorbing component prevents the platform 4 and the artifact it carries from shaking. This effectively prevents irregularly shaped artifacts from shaking on the surface of the platform 4, ensuring the stability of the artifact and providing protection.

[0027] Specifically, such as Figure 5As shown, each shock-absorbing component includes a pad 62 fixed to the top of the movable seat 6. The top of each pad 62 is connected to a docking ring 64 via a pressure spring 63. The top of each docking ring 64 is fixedly connected to a shock-absorbing sleeve 65. The pad 62, pressure spring 63, docking ring 64 and shock-absorbing sleeve 65 are all arranged around the outside of the limiting rod 61 and are coaxially distributed with the limiting rod 61.

[0028] The inner side of the shock-absorbing sleeve 65 has an inverted frustum-shaped accommodating space. As the slide rod 51 descends, the alignment sleeve 52 descends to the inner side of the shock-absorbing sleeve 65, abutting against the inclined inner wall of the shock-absorbing sleeve 65. The shock-absorbing sleeve 65 can effectively stop the alignment sleeve 52 from descending to its limit height. The elastic potential energy of the shock-absorbing sleeve 65 itself can buffer the impact force of the platform 4 and the cultural relic with a certain weight descending in a straight line. Furthermore, combined with the pad block 62 and the pressure spring 63 located below it, since the pressure spring 63 can be compressed and quickly reset under the impact force, the combination of the shock-absorbing sleeve 65 and the pressure spring 63 can effectively absorb the impact force generated when the platform 4 and the cultural relic descend in a straight line, avoiding the shaking phenomenon that occurs after the platform 4 and the cultural relic descend rapidly, thus improving the stability of the cultural relic.

[0029] like Figure 4 As shown, in this utility model, to enable the support plate 5 and the platform 4 to move smoothly up and down, two parallel linkage racks 53 are fixed to the bottom of the support plate 5. Each of the two linkage racks 53 is meshed with the same electric gear set 54 on one side. The electric gear set 54 is fixed to the movable seat 6 via a mounting bracket. Under the operation of the electric gear set 54, the two linkage racks 53 and the support plate 5 can move up and down, the platform 4 can move up and down, and the sliding rod 51 and the alignment sleeve 52 move synchronously up and down along the surface of the limiting rod 61.

[0030] like Figure 4 As shown, a driver 41 is located below the support plate 5, and the output end of the driver 41 is installed through the central axis between the support plate 5 and the stage 4. During the CT scan imaging operation on the cultural relic, when the driver 41 is running, the stage 4 rotates within the relative space between the X-ray source 2 and the detector 3, allowing the cultural relic to receive the CT scan imaging operation evenly and comprehensively, ensuring the accuracy of the subsequently generated images.

[0031] Example 2: Based on Example 1, such as Figure 2 , Figure 3 As shown, when the cabin 1 is opened, in order to allow the movable seat 6 and the support plate 5 to move smoothly to the cabin door of the cabin 1 so that the staff can place the cultural relics on the surface of the platform 4 smoothly, in this utility model, the bottom end of the movable seat 6 is fixed with a first slider 7, and a Y-axis linear module 8 adapted to it is installed on the first slider 7. When the Y-axis linear module 8 is running, the first slider 7, the movable seat 6, the support plate 5 and the platform 4 move synchronously along the Y-axis direction.

[0032] Furthermore, in this utility model, a second slider 9 is fixed at the bottom of the Y-axis linear module 8, and an X-axis linear module 10 adapted to it is installed on the second slider 9. The X-axis linear module 10 is fixed inside the cabin 1. When the X-axis linear module 10 is running, the second slider 9, the Y-axis linear module 8, the first slider 7 and the moving seat 6 move synchronously along the X-axis direction.

[0033] In summary, under the operation of the Y-axis linear module 8 and the X-axis linear module 10, the moving seat 6 and the support plate 5 can be flexibly adjusted in position along the Y-axis and X-axis directions inside the cabin 1, which makes it easy for staff to place the cultural relics on the surface of the platform 4. The platform 4 carrying the cultural relics can move with the moving seat 6 and the support plate 5 to the position facing the X-ray source 2 to receive CT scanning imaging.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
