This technology utilizes the penetrating properties of X-rays and the differential absorption of X-rays by different materials to perform nondestructive testing for internal defects, structural integrity, and assembly quality. When X-rays pass through metal casings, they are attenuated to varying degrees depending on the material's thickness, density, and the presence of defects (such as pores and cracks).

The side of the guide slider is rotatably connected to a straightening wheel, and the snake tube is located in the opening of the straightening wheel.
[0012] Optionally, the side of the guide slider is rotatably connected to a winding rod, the straightening wheel is rotatably connected to the winding rod, a torque spring is elastically connected between the winding rod and the guide slider, a metal wire is fixedly installed between the middle part of the snake tube and the winding rod, and the metal wire is wound on the winding rod.

[0017] Furthermore, since a certain length of the snake tube needs to be reserved, when the connecting slider slides toward the syringe, the straightening wheel slides away from the syringe, so that the snake tube is always in a straightened state, avoiding it from obstructing the connecting slider and preventing the snake tube from being squeezed by the connecting slider, which not only causes damage to the snake tube, but also causes the connecting slider to encounter obstacles during sliding, affecting the scanning of the CT scanning device.
[0018] Furthermore, the tension of the lubricating oil causes the lubricating oil to adhere to the brush, reducing the flow rate of the lubricating oil and preventing the lubricating oil from flowing quickly to the bottom of the coupled slider, resulting in a large amount of lubricating oil not participating in the lubrication of the coupled slider and the first screw, and under the action of the brush, the coating is more evenly applied.

DETAILED DESCRIPTION
[0021] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0022] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention.
[0023] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
[0024] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0025] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.
[0026] Example 1: This example proposes a CT detection device with a metal shell, such as Figure 1 As shown, the system comprises a base frame 1, with a scanning cantilever 2 slidably connected to the side of the base frame 1. A CT scanner 3 is slidably connected to the interior of the scanning cantilever 2. A scanning control device 4 is fixedly mounted on the side of the scanning cantilever 2. The scanning cantilever 2 raises and lowers the CT scanning height. For example, for a large metal shell, the scanning cantilever 2 can raise and lower the CT scanning height to traverse the metal shell, achieving comprehensive inspection of the metal shell.
[0027] A cantilever auxiliary mechanism 5 is provided inside the scanning cantilever frame 2, and the cantilever auxiliary mechanism 5 includes a first screw 52. Both ends of the first screw 52 are rotatably connected to the scanning cantilever frame 2. A connecting slider 51 is threadedly connected to the first screw 52. The interior of the scanning cantilever frame 2 is rotatably connected to a centrifugal shaft 55. A motor is provided at the end of the first screw 52. A transmission member is provided between the first screw 52 and the centrifugal shaft 55. The transmission member includes a first gear 53 and a second gear 54. The first gear 53 is fixedly installed at the end of the first screw 52. The end of the centrifugal shaft 55 is fixedly installed with a second gear 54. The first gear 53 is meshed with the second gear 54. The diameter of the first gear 53 is five times the diameter of the second gear 54.
[0028] When the CT scanning device 3 experiences a sliding jam, it indicates that the friction between the first screw 52 and the associated slider 51 increases, the rotational speed of the first screw 52 decreases, and the first screw 52 drives the centrifugal shaft 55 to rotate via the first gear 53 and the second gear 54. Due to the gear ratio of the first gear 53 and the second gear 54, when the first screw 52 rotates one circle, the centrifugal shaft 55 rotates several circles to increase the rotational speed of the centrifugal shaft 55. Therefore, when the rotational speed of the first screw 52 decreases, the rotational speed of the centrifugal shaft 55 changes significantly.
[0029] A centrifugal rod 56 is fixedly mounted perpendicular to the outer wall of the centrifugal shaft 55. A centrifugal slider 57 is slidably connected to the centrifugal rod 56. A coil spring 58 is elastically connected between the end of the slider 57 and the centrifugal shaft 55. A pressure block 59 has a truncated cone-shaped groove on the side facing the slider 57, and the slider 57 contacts the groove of the pressure block 59. A pressure block 59 is slidably connected to the outer wall of the centrifugal shaft 55, contacting the inclined surface of the slider 57. A syringe 511 is fixedly mounted on the inner wall of the scanning cantilever 2, located in the sliding path of the pressure block 59.
[0030] When the CT scanning device 3 slides normally, the centrifugal slider 57 is subjected to a large centrifugal force, and the centrifugal slider 57 stretches the coil spring 58 and squeezes the pressure block 59. When the cantilever auxiliary mechanism 5 slides and gets stuck, the centrifugal force on the centrifugal slider 57 is reduced, and the centrifugal slider 57 is reset by the coil spring 58, so that the centrifugal slider 57 no longer squeezes the pressure block 59.
[0031] Since the syringe 511 is internally provided with a piston having a reset function, when the centrifugal slider 57 no longer presses the pressure block 59 , the piston resets to squeeze out the lubricating oil in the syringe 511 .
[0032] A snake tube 512 is provided inside the scanning cantilever frame 2, one end of the snake tube 512 is fixedly connected to the syringe 511, and the other end of the snake tube 512 is fixedly connected to the carrying slider 51. The lubricating oil in the syringe 511 enters the first screw 52 and is threadedly connected to the carrying slider 51. As the position of the first screw 52 and the CT scanning device 3 changes, lubricating oil is applied to the connection between the carrying slider 51 and the first screw 52 to prevent the CT scanning device 3 from getting stuck, causing the image scanned by the CT scanning device 3 to be unclear.
[0033] In this embodiment, when the CT scanning device 3 jams during operation, the rotation speed of the first screw 52 is affected, so that the centrifugal force on the centrifugal slider 57 connected to the centrifugal shaft 55 is reduced. At this time, the centrifugal slider 57 slides toward the centrifugal shaft 55 and no longer squeezes the pressure block 59. The piston with a reset function in the syringe 511 is used to squeeze the hydraulic oil into the carrying slider 51, thereby reducing the jamming of the CT scanning device 3 during the sliding process, thereby preventing the CT scanning device 3 from jamming and causing the image scanned by the CT scanning device 3 to be unclear.
[0034] Example 2. Based on Example 1, this example proposes a CT detection device with a metal shell. A pipeline auxiliary mechanism 6 is provided inside the scanning cantilever frame 2. The pipeline auxiliary mechanism 6 includes a second screw 61. Both ends of the second screw 61 are rotatably connected to the scanning cantilever frame 2. The second screw 61 and the first screw 52 are parallel to each other. A guide slider 64 is threadedly connected to the second screw 61. The moving directions of the connecting slider 51 and the guide slider 64 are opposite. A fourth gear 63 is fixedly installed at the end of the first screw 52, and a third gear 62 is fixedly installed at the end of the second screw 61. The third gear 62 is meshed with the fourth gear 63. The side of the guide slider 64 is rotatably connected to the straightening wheel 66, and the snake tube 512 is located in the opening of the straightening wheel 66.
[0035] Since the connecting slider 51 and the syringe 511 need to be connected by a snake tube 512, a certain length of the snake tube 512 needs to be reserved. However, when the distance between the connecting slider 51 and the syringe 511 is close, an excessively long snake tube 512 will hinder the sliding of the connecting slider 51. Therefore, the snake tube 512 is stretched by the straightening wheel 66. When the connecting slider 51 slides toward the syringe 511, the straightening wheel 66 slides away from the syringe 511, so that the snake tube 512 is always in a straightened state to prevent it from hindering the connecting slider 51.
[0036] The side of the guide slider 64 is rotatably connected to the winding rod 65, the straightening wheel 66 is rotatably connected to the winding rod 65, a torque spring 68 is elastically connected between the winding rod 65 and the guide slider 64, and a metal wire 67 is fixedly installed between the middle part of the snake tube 512 and the winding rod 65, and the metal wire 67 is wound on the winding rod 65.
[0037] A metal wire 67 connects to the snake tube 512 to prevent it from misaligning and becoming out of alignment with the straightening wheel 66. The snake tube 512 is a flat, tubular structure. A slit is defined within the scanning cantilever 2 to limit the left-right bending of the snake tube 512. A metal extension tube 69 is fixed between the connecting slider 51 and the snake tube 512 to further restrict its bending direction.
[0038] In this embodiment, since a certain length of the snake tube 512 needs to be reserved, when the connecting slider 51 slides toward the syringe 511, the straightening wheel 66 slides in the direction away from the syringe 511, so that the snake tube 512 is always in a straightened state, avoiding it from obstructing the connecting slider 51 and preventing the snake tube 512 from being squeezed by the connecting slider 51, which not only causes damage to the snake tube 512, but also causes the connecting slider 51 to encounter obstacles during the sliding process, affecting the scanning of the CT scanning device 3.
[0039] Example 3. Based on the above-mentioned Example 1 or Example 2, this example proposes a CT detection device with a metal shell. A coating mechanism 7 is provided inside the connecting slider 51. The coating mechanism 7 includes a supporting thin rod 73. The supporting thin rod 73 is fixedly installed inside the connecting slider 51. A brush 74 is fixed to the bottom of the supporting thin rod 73. The bottom of the brush 74 is in contact with the first screw 52. The lubricating oil is absorbed by the brush 74, and the tension of the lubricating oil is used to make the lubricating oil adhere to the brush 74, thereby preventing the lubricating oil from flowing directly to the bottom of the connecting slider 51. At the same time, since the amount of lubricating oil squeezed out by the syringe 511 is limited, the tension of the brush 74 and the lubricating oil is used to avoid waste of lubricating oil.
[0040] A first straight hole 71 is provided inside the connecting slider 51 and is connected to the metal wire 67 . A second straight hole 72 is also provided inside the connecting slider 51 and a supporting rod 73 is located inside the second straight hole 72 . The first straight hole 71 is connected to the second straight hole 72 and the supporting rod 73 supports the brush 74 .
[0041] In this embodiment, the tension of the lubricating oil causes the lubricating oil to adhere to the brush 74, reducing the flow rate of the lubricating oil and preventing the lubricating oil from flowing quickly to the bottom of the connecting slider 51, resulting in a large amount of lubricating oil not participating in the lubrication of the connecting slider 51 and the first screw 52, and under the action of the brush 74, the coating is more evenly applied.
[0042] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
