Description

Technical Field

[0001] This utility model relates to the field of CT equipment technology, and in particular to a support module and CT equipment based on CT equipment. Background Technology

[0002] CT (Computed Tomography) is used for medical scanning, security screening, and other applications. CT equipment typically consists of an X-ray source and a detector, both fixed on a rotating support and rotating around the scanning channel to obtain omnidirectional scan images.

[0003] Currently, the rotating support of CT equipment typically uses a large disc as a base plate, fixed to a bearing. Functional components such as the detector housing and X-ray source are fixed to the disc surface with fixing screws perpendicular to the disc surface. When the rotating support operates at high speed, the functional components are subjected to centrifugal force, tending to shift outwards. Correspondingly, the fixing screws are subjected to shear force, easily leading to loosening and insufficient fixation. Therefore, to ensure the fixation strength and stability of the functional components under high-speed rotation, reinforcement structures are usually required. However, these additional reinforcement structures increase the size and weight of the equipment, increasing costs, and are inconvenient to disassemble and assemble, reducing maintenance efficiency. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a support module and CT equipment based on CT equipment, so as to solve the problem that the existing rotating support usually requires the setting of a reinforcement structure to reinforce the functional firmware. However, the additional reinforcement structure increases the size and weight of the equipment, increases the cost, and is inconvenient to disassemble and assemble, which reduces maintenance efficiency.

[0019] To address the issue that existing rotating brackets typically require reinforcement structures to strengthen functional components, which increases equipment size and weight, raises costs, and is inconvenient to assemble and disassemble, thus reducing maintenance efficiency.

[0020] This utility model provides a support module based on a CT scanner. The cast support body includes a front panel and a rear panel, with windows in the middle of both panels to form a scanning channel. An annular partition surrounding the scanning channel is provided between the front and rear panels, along with a top plate and side plates located outside the annular partition. A detector mounting cavity is formed at the lower part of the front and rear panels. The detector, installed in the mounting cavity, can be fixed between the front and rear panels, ensuring the detector's light-shielding requirements and providing high reliability. The fixing bolts for the functional components mounted on the top and side plates are easily arranged radially. When rotating with the support body, the centrifugal force direction is aligned with the axis of the fixing bolts, resulting in high reliability. This effectively improves the reliability of the functional components, reduces the need for reinforcement structures, lowers costs, reduces assembly / disassembly complexity, and improves maintenance efficiency.

[0021] Specifically, please refer to Figures 1 to 5The CT-based support module in this embodiment is mainly composed of a cast support body. The support body includes a front plate 11 and a rear plate 12. Windows are opened in the middle of both the front and rear plates 11 to form a scanning channel. The rear plate 12 has bearing bolt mounting holes for mounting bearing bolts 123, which are then fixed to the bearings of the CT equipment, allowing the entire assembly to rotate. The support body is symmetrical front to back. The bearing bolt mounting holes can be located on any plate, or, if the CT equipment has multiple bearings, both the front and rear plates can connect to corresponding bearings.

[0022] An annular partition 13 surrounding the scanning channel is provided between the front plate surface 11 and the rear plate surface 12, and a top plate 14 and a side plate 15 are provided outside the annular partition 13. The top of the annular partition 13 communicates with the top plate 14 and is provided with an opening to form a ray outlet 141 between the top of the annular partition 13 and the top plate 14. Figure 2 and Figure 3 As shown, the X-ray outlet 141 connects the top of the annular partition 13 and the top plate 14. The X-ray source is fixed on the top plate 14, and the emitted X-rays are emitted into the scanning channel through the X-ray outlet 141. A lead plate is also fixedly covered on the annular partition 13 for X-ray isolation.

[0023] Side plate 15 can be used for the installation of functional components such as water cooling systems and controllers. The X-ray source fixed on top plate 14 and the functional components fixed on side plate 15 can be set perpendicular to the surface of top plate 14 or side plate 15. Correspondingly, the axial direction of their fixing bolts is arranged along the radial direction of the bracket body. When rotating with the bracket body, the shear force on the fixing bolts can be reduced, and the fixing stability of the fixing bolts can be improved.

[0024] An annular partition 13 is spaced apart from the edges of the front panel 11 and the rear panel 12, and a light-shielding window 131 is provided at the lower part of the annular partition 13 to form a detector mounting cavity 16 at the lower part of the front panel 11 and the rear panel 12. A cover plate mounting hole is provided at the lower edge of the front panel 11 and the rear panel 12. The bracket body, combined with the light-shielding window 131, provides a fixed light-shielding plate, and the cover plate at the lower edge of the front panel 11 and the rear panel 12, achieves optical sealing of the detector installed in the detector mounting cavity 16, preventing external light interference with the detector's X-ray detection. The light-shielding plate is mainly used for shielding visible light and preventing X-ray transmission. The cover plate also blocks X-rays to prevent them from affecting the outside of the equipment, ensuring safety. The cover plate can be made of materials such as aluminum alloy or stainless steel, and is covered with a fixed lead plate to ensure X-ray blocking.

[0025] To facilitate the installation of the detector 21, the front plate 11 and the rear plate 12 also include a boss 162 protruding into the detector mounting cavity 16. The side wall of the boss 162 is provided with a detector mounting hole. The fixed end face of the detector 21 fits against the side wall of the boss 162 and is fixed by the detector mounting hole and bolt. The axis of the bolt is set along the radial direction of the bracket body. When the bracket body rotates, the bolt is subjected to the axial force of the bolt, which can avoid the influence of shear force and improve the fixing reliability.

[0026] The boss 162 can also improve the structural strength of the front plate 11 and the rear plate 12, thereby improving the fixation stability of the detector 21.

[0027] In this embodiment, a mounting component 17 is also included. The front panel 11 and the rear panel 12 also include mounting component mounting grooves 161, which have openings and screw holes, such as... Figure 4 As shown, the mounting component 17 includes a base plate 171 that is screwed into and fitted with the groove surface of the mounting component mounting groove 161, and a mounting plate 172 extending from the base plate 171. The mounting plate 172 can extend from the opening in the mounting component mounting groove 161 into the detector mounting cavity (e.g., Figure 1 and Figure 5 As shown, the mounting plate 172 has detector mounting holes on its side wall. After the mounting component 17 is fixed in the mounting component setting groove 161, the fixed end face of the detector 21 is attached to the side wall of the mounting plate 172 and screwed in. Correspondingly, the axis of the fixing bolt is set along the radial direction of the bracket body, which can reduce the shear force on the fixing bolt and improve the fixing effect.

[0028] In this embodiment, the boss 162 is located in the middle, and the mounting slots 161 are arranged at both ends, which are used for the installation of the main detector and the auxiliary detector, respectively. In practice, the boss 162 and the mounting slots 161 can be flexibly selected according to specific needs, or the arrangement of the two can be adjusted.

[0029] Since the lower part of the detector mounting cavity 16 is open to facilitate the installation of the detector, in order to improve the structural strength of the open lower part, in this embodiment, the lower edges of the front plate surface 11 and the rear plate surface 12 are provided with reinforcing rib mounting grooves 163. The reinforcing rib mounting grooves 163 are interposed between the mounting holes of the closed cover plate, and the reinforcing ribs 18 are provided in the reinforcing rib mounting grooves 163. The lower edges of the front plate surface 11 and the rear plate surface 12 can be connected and supported by the reinforcing ribs 18, thereby improving the shape retention capability of the detector mounting cavity 16, and thus ensuring the fixation stability of the detector fixed in the detector mounting cavity 16, as well as the installation stability of the closed cover plate.

[0030] To facilitate docking with the bearing, in this embodiment, as follows: Figure 2As shown, the outer side of the rear plate 12 is provided with a recessed platform 121 that mates with the bearing. The bearing bolt mounting holes are arranged around the recessed platform 121, and can be aligned and positioned with the bearing through the recessed platform 121. The inner ring of the recessed platform 121 is also provided with a keyway, so as to align with the bearing in the circumferential direction. The positioning of the bearing bolt mounting holes on the rear plate 12 is achieved by positioning the keyway with the bolt holes on the bearing.

[0031] To improve the structural strength of the side plate 15, in this embodiment, the side plate 15 is provided with inclined reinforcing ribs 151.

[0032] To reduce weight, in this embodiment, weight-reducing grooves 101 are provided on the outer surfaces of the front panel 11, rear panel 12, top panel 14, and side panel 15.

[0033] This utility model also provides a CT device, including the aforementioned support module, an X-ray source mounted on the top plate, and a detector mounted in the detector mounting cavity. The axes of the fixing bolts for each function are arranged radially, thereby reducing the shear force on the fixing bolts when the device rotates, improving the fixing reliability. The functional fasteners are installed on the outside of the top plate and side plates, which facilitates the integral casting of the support body, improves the structural strength of the support body, reduces the need for fixing structures, reduces the overall weight, reduces the disassembly and assembly requirements for maintenance, and improves maintenance efficiency.

[0034] This utility model provides a CT equipment-based support module and a CT equipment support body, including a front panel and a rear panel. Windows are opened in the middle of the front and rear panels to form a scanning channel. An annular partition surrounding the scanning channel is provided between the front and rear panels, along with a top plate and side plates located outside the annular partition. A detector mounting cavity is formed in the lower part of the front and rear panels. The detector installed in the detector mounting cavity can be fixed between the front and rear panels, ensuring the light-shielding requirements for detector operation and providing high fixation reliability. The fixing bolts of the functional components mounted on the top and side plates are conveniently arranged radially. When rotating with the support body, the centrifugal force direction is consistent with the axis of the fixing bolts, resulting in high fixation reliability. This effectively improves the fixation reliability of the functional components, reduces the need for reinforcement structures, lowers costs, reduces disassembly and assembly complexity, and improves maintenance efficiency.
