Description

Technical Field

[0001] This invention relates to the field of high voltage generator technology, specifically to a CT high voltage generator maintenance auxiliary device with fault early warning. Background Technology

[0002] The CT high-voltage generator, as the core component that converts low-voltage electricity into high-voltage electricity, has a large workload and a high failure rate, requiring regular maintenance. However, existing disassembly techniques face the following problems: Spatial structure constraints The internal layout of a CT scanner is compact (such as a rotating gantry integrated design). The high-voltage generator is usually closely adjacent to components such as the X-ray tube and detector, resulting in insufficient available operating space. Although modern high-voltage generators adopt an integrated cabinet design, their irregular shape further restricts the intervention of external support equipment. Disassembly compatibility defects Shape mismatch: The non-standard structure of the high-voltage generator (such as protruding modules and irregular interfaces) makes it impossible for general support equipment to fit the stress points, which can easily lead to slippage or local stress concentration during disassembly; the non-standard structure causes uneven weight distribution of the high-voltage generator, resulting in a shift in the center of gravity, making it difficult for traditional hoisting equipment to balance the load.

[0003] Based on this, the present invention designs a CT high-voltage generator maintenance auxiliary device with fault early warning to solve the above problems. Summary of the Invention

Detailed Implementation

[0018] Please see Figure 1-11This invention provides a technical solution: a CT high-voltage generator maintenance auxiliary device with fault early warning, comprising a base 1, a fixing frame 2 fixedly connected to the top of the base 1, a sliding plate 3 slidably connected inside the fixing frame 2, and an adjustment locking mechanism on the sliding plate 3, comprising two threaded cylinders 8, each of which is respectively disposed at the front end of the sliding plate 3. A threaded sleeve 14 is helically connected to the front end of each threaded cylinder 8, and a drive disc 11 is rotatably connected to the front end of the threaded sleeve 14. A support base 12 is fixedly connected to the top of the drive disc 11. A locking component is disposed inside the threaded cylinder 8, which is used to fix the drive disc 11 to the front end of the sliding plate 3 and restrict its rotation when the support base 12 supports the high-voltage generator; an adjustment component is disposed at the front end of the sliding plate 3, which is used to change the position of the threaded cylinder 8. See Figures 1-2 The entire device is moved to one side of the CT machine. The sliding plate 3 is adjusted to a suitable height. The position of the two support seats 12 is adjusted by the adjustment component. Then, the drive disk 11 is flipped so that the support seats 12 contact the bottom left and right sides of the high voltage generator. The position of the adjustment component is locked to fix the position of the drive disk 11. The position of the support seats 12 is then locked by the locking component so that the support seats 12 do not shift at an angle when supporting the high voltage generator. The CT high voltage generator is supported by external insertion. This method is suitable for CT machines with compact internal parts and irregular bottom support surfaces. The support seats 12 on both sides are adjusted according to the height of the two end faces of the high voltage generator. The drive disk 11 can adjust the angle of the support seats 12 to support the bottom surface at different angles.

[0019] As a further embodiment of the present invention, the adjusting assembly includes a second lead screw 7, which is disposed at the front end of the sliding plate 3. Both sides of the second lead screw 7 are respectively screwed with a first lead screw 5, and both first lead screws 5 are respectively fixed to the front end of the sliding plate 3. A drive seat 6 is screwed onto the second lead screw 7, and the threaded cylinder 8 is fixed to the front end of the drive seat 6. See Figure 2 When the sliding plate 3 moves to a suitable height on the fixed frame 2, the horizontal position of the drive seat 6 on the second lead screw 7 and the vertical position of the second lead screw 7 on the first lead screw 5 are adjusted according to the specific position of the high voltage generator, thereby adjusting the planar coordinates of the support seat 12. After the adjustment is completed, the rotation of the first lead screw 5 and the second lead screw 7 is locked to fix the drive seat 6, and the support seats 12 on both sides can be adjusted individually, which can effectively support the high voltage generator with opposite bottom surfaces on both sides.

[0020] As a further embodiment of the present invention, the locking assembly includes a rotating rod 13, which is fixedly connected to the output end of the lead screw 7. The rotating rod 13 is slidably sleeved inside the threaded sleeve 14. A connecting disc 10 is rotatably connected to the front end of the threaded sleeve 14. The driving disc 11 is slidably connected to the connecting disc 10 via a sliding rod 9. A plurality of ring-shaped limiting blocks 20 are slidably connected to the rear end of the driving disc 11. A rotating cylinder 24 is slidably connected inside the threaded sleeve 14. A threaded rod 23 is fixedly connected to the front end of the rotating cylinder 24. A useful... The limiting block 20 has a tapered plate 22 fixedly connected to its rear end for contacting the threaded sleeve 14, and a rotating cylinder 16 is rotatably sleeved on the outside of the rotating cylinder 24. The rotating cylinder 16 has several sliding grooves 17. The inner wall of the threaded sleeve 14 has a protrusion 18 fixedly connected for engaging with the sliding grooves 17. The rear end of the rotating cylinder 24 has a stop block 19 that can contact the protrusion 18. The rear end of the drive disc 11 has a connecting shaft 15 fixedly connected. The connecting shaft 15 slides through the rotating cylinder 24 and is disposed inside the threaded sleeve 14. See Figures 3-11 When adjusting the position of the drive seat 6, manually pull up the drive plate 11 to slide relative to the connecting plate 10, so that the support seat 12 slides from the outside to the bottom of the high-voltage generator. Then rotate the support seat 12 to make it fit against the bottom of the high-voltage generator and lock the position of the drive seat 6. Manually keep the support seat 12 in contact with the high-voltage generator. At this time, start the drive seat 6 to drive the rotating rod 13 to rotate. The rotating rod 13 drives the threaded sleeve 14 to rotate synchronously. Since the threaded sleeve 14 is helically connected to the threaded cylinder 8, the threaded sleeve 14 rotates with the rotating rod 13. While rotating, the threaded sleeve 14 slides relative to the rotating rod 13, thereby pushing the connecting plate 10 to gradually slide closer to the driving plate 11; at the same time, the threaded sleeve 14 drives the protrusion 18 to rotate, and the protrusion 18 drives the rotating cylinder 16 to rotate through the sliding groove 17. The rotating cylinder 16 drives the rotating cylinder 24 to rotate together through the one-way bearing 25, so that the rotating cylinder 24 and the threaded sleeve 14 rotate synchronously; when the threaded sleeve 14 rotates to contact the cone plate 22, the threaded sleeve 14 will push the limiting block 20 to slide outward along the cone plate 22. Figures 7-10 As shown, when the limiting block 20 slides to the outermost side, the threaded rod 23 will contact the inner side of the limiting block 20, and gradually connect with the limiting block 20 by the rotation of the threaded rod 23 until the threaded sleeve 14 slides to the farthest distance. At this time, the drive disk 11 is fixed on the threaded sleeve 8 by the threaded connection between the limiting block 20 and the threaded rod 23. At this time, the fixing of the support seat 12 is completed, and the support seat 12 plays a supporting role for the high voltage generator. When the high-voltage generator is removed from the CT machine and only the support base 12 supports it, the start drive base 6 drives the rotating rod 13 to flip, and the threaded sleeve 14 will slide backward to reset. At this time, the threaded sleeve 14 drives the rotating cylinder 16 to flip through the protrusion 18. However, due to the action of the one-way bearing 25, the rotating cylinder 16 cannot be transmitted to the rotating cylinder 24. That is, the threaded rod 23 at the front end of the rotating cylinder 24 is still fixed to the drive plate 11. The high-voltage generator can then be removed from the CT machine through the support base 12. While the threaded sleeve 14 drives the rotating cylinder 16 to rotate, the protrusion 18 slides along the slide groove 17 until the protrusion 18 contacts the stop block 19. The protrusion 18 drives the rotating cylinder 24 to rotate through the stop block 19, which can disengage the threaded rod 23 from the screw connection with the limit block 20, so that the drive plate 11 can be rotated and used again.

[0021] As a further aspect of the present invention, a strong spring for resetting the limiting block 20 is fixedly connected inside the driving disk 11, and the limiting block 20 is provided with a through groove for engaging with the sliding rod 9, such as... Figure 8 As shown, after the limiting block 20 is pressed by the threaded sleeve 14 to the position where it mates with the sliding rod 9, when the threaded sleeve 14 disengages from the limiting block 20, the limiting block 20 can automatically reset under the action of the strong spring.

[0022] As a further embodiment of the present invention, a drive motor 4 is fixedly connected to the front end of the sliding plate 3, and the output shaft of the drive motor 4 is fixedly connected to the lead screw 5. The drive motor 4 drives the lead screw 5 to rotate, thereby adjusting the horizontal height of the lead screw 7.

[0023] As a further embodiment of the present invention, the base 1 is rotatably connected to the bottom of the four sides, and the bottom casters facilitate the transportation of the entire device.

[0024] As a further embodiment of the present invention, a driving component is fixedly connected to the top of the fixed frame 2, and the output end of the driving component is fixedly connected to the sliding plate 3. The driving component drives the sliding plate 3 to slide up and down inside the fixed frame 2, so that the sliding plate 3 is adjusted to a suitable height to connect with the high voltage generator.

[0025] As a further embodiment of the present invention, a high-friction anti-slip pad is fixedly connected to the front end of the rotating cylinder 16. The anti-slip pad increases the friction and reduces wear, resulting in a lower wear rate between the rotating cylinder 16 and the threaded rod 23.

[0026] As a further embodiment of the present invention, the connecting plate 10 is provided with a slot 21 for docking with the cone plate 22. When the threaded sleeve 14 slides to the position where it docks with the limiting block 20, the cone plate 22 can pass through the slot 21 and dock with the connecting plate 10, thereby further restricting the shaking of the limiting block 20 through the slot 21.

[0027] Working principle: Move the entire device to one side of the CT scanner, and adjust the sliding plate 3 to a suitable height. According to the specific location of the high voltage generator, adjust the horizontal position of the drive seat 6 on the second lead screw 7 and the vertical position of the second lead screw 7 on the first lead screw 5, thereby adjusting the planar coordinates of the support seat 12. After the adjustment is completed, lock the rotation of the first lead screw 5 and the second lead screw 7 to fix the drive seat 6, and the support seats 12 on both sides can be adjusted individually. When adjusting the position of the drive seat 6, manually pull up the drive plate 11 to slide relative to the connecting plate 10, so that the support seat 12 slides from the outside to the bottom of the high voltage generator. Then rotate the support seat 12 to make it fit against the bottom of the high voltage generator and lock the position of the drive seat 6. Manually keep the support seat 12 in contact with the high voltage generator. At this time, start the drive seat 6 to drive the rotating rod 13 to rotate. The rotating rod 13 drives the threaded sleeve 14 to rotate synchronously. Since the threaded sleeve 14 is helically connected to the threaded cylinder 8, the threaded sleeve 14 moves with the rotating rod 13. While rotating, the threaded sleeve 14 slides relative to the rotating rod 13, thereby pushing the connecting plate 10 to gradually slide closer to the driving plate 11; at the same time, the threaded sleeve 14 drives the protrusion 18 to rotate, and the protrusion 18 drives the rotating cylinder 16 to rotate through the sliding groove 17. The rotating cylinder 16 drives the rotating cylinder 24 to rotate together through the one-way bearing 25, so that the rotating cylinder 24 and the threaded sleeve 14 rotate synchronously; when the threaded sleeve 14 rotates to contact the cone plate 22, the threaded sleeve 14 will push the limiting block 20 to slide outward along the cone plate 22. Figures 7-10 As shown, when the limiting block 20 slides to the outermost side, the threaded rod 23 will contact the inner side of the limiting block 20, and gradually connect with the limiting block 20 by the rotation of the threaded rod 23 until the threaded sleeve 14 slides to the farthest distance. At this time, the drive disk 11 is fixed on the threaded sleeve 8 by the threaded connection between the limiting block 20 and the threaded rod 23. At this time, the fixing of the support seat 12 is completed, and the support seat 12 plays a supporting role for the high voltage generator. When the high-voltage generator is removed from the CT machine and only the support base 12 supports it, the start drive base 6 drives the rotating rod 13 to flip, and the threaded sleeve 14 will slide backward to reset. At this time, the threaded sleeve 14 drives the rotating cylinder 16 to flip through the protrusion 18. However, due to the action of the one-way bearing 25, the rotating cylinder 16 cannot be transmitted to the rotating cylinder 24. That is, the threaded rod 23 at the front end of the rotating cylinder 24 is still fixed to the drive plate 11. The high-voltage generator can then be removed from the CT machine through the support base 12. While the threaded sleeve 14 drives the rotating cylinder 16 to rotate, the protrusion 18 slides along the slide groove 17 until the protrusion 18 contacts the stop block 19. The protrusion 18 drives the rotating cylinder 24 to rotate through the stop block 19, which can disengage the threaded rod 23 from the screw connection with the limit block 20, so that the drive plate 11 can be rotated and used again.
