[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Understandably, referring to Figure 1 , Figure 2 , Figure 5 and Figure 6The medical detector driving device of this utility model includes a lifting mechanism 100, a rotating mechanism 200, and a mounting frame 300. The lifting mechanism 100 includes a column 110, a slide 120, and a first driving member. The slide 120 is slidably connected to the column 110, and the first driving member is used to drive the slide 120 to move up and down on the column 110. The rotating mechanism 200 includes a bearing seat 210, a rotating shaft 220, and a second driving member 230. The bearing seat 210 is fixedly connected to the slide 120, and both ends of the bearing seat 210 are equipped with support bearings 211. The rotating shaft 220 connects the two support bearings 211, and the second driving member 230 is used to drive the rotating shaft 220 to rotate. The mounting frame 300 is fixedly connected to the rotating shaft 220, and the center line of the mounting frame 300 coincides with the axis of the rotating shaft 220. The mounting frame 300 is used to mount the detector 310.

[0033] The column 110 is vertically arranged, the slide 120 is slidably connected to the column 110, the bearing seat 210 is fixedly connected to the slide 120, and two support bearings 211 are respectively arranged at both ends of the bearing seat 210. One end of the rotating shaft 220 is rotatably connected to the two support bearings 211, and the other end is fixedly connected to the mounting frame 300. The first driving member can drive the slide 120 to move up and down on the column 110, so that the mounting frame 300 can move in the vertical direction. The second driving member 230 can drive the rotating shaft 220 to rotate, so that the mounting frame 300 can rotate. Thus, the detector 310 can move up and down in the vertical direction and can rotate, meeting the imaging needs of different parts of the patient, making the position of the detector 310 flexible and easy to adjust.

[0034] In addition, by connecting the rotating shaft 220 to two support bearings 211, the positional accuracy of the rotating shaft 220 can be improved, allowing the rotating shaft 220 to be accurately positioned on the bearing seat 210. Furthermore, the two support bearings 211 can enhance the support for the rotating shaft 220, stabilizing its position and reducing the possibility of positional deviation. Moreover, the centerline of the mounting bracket 300 coincides with the axis of the rotating shaft 220, which can reduce the bending load on the rotating shaft 220 caused by the weight of the mounting bracket 300, enabling the rotating shaft 220 to be subjected to force balance, thereby reducing the bending deformation of the rotating shaft 220, improving the positional stability of the mounting bracket 300, and enhancing the imaging accuracy of the detector 310.

[0035] The centerline of the mounting bracket 300 can be understood as the axis of symmetry passing through the geometric center of the mounting bracket 300, so as to reduce the torque formed on the rotating shaft 220 by the weight of the mounting bracket 300 and the detector 310, so that the rotating shaft 220 can be balanced by forces, reduce the possibility of bending and displacement, and improve reliability.

[0036] It should be noted that the first driving component can be a linear hydraulic cylinder, an electric cylinder, or a motor combined with a chain drive, belt drive, or other transmission mechanism; the second driving component 230 can be a motor, a pneumatic motor, a swing cylinder, etc., and is not limited here.

[0037] Understandably, referring to Figure 2 , Figure 5 and Figure 6 The rotating mechanism 200 also includes a fixed frame 240, on which a plurality of fasteners 241 are passed. The fasteners 241 are arranged at intervals along the circumference of the fixed frame 240. The fasteners 241 are threadedly connected to the slide 120. The bearing seat 210 is fixedly connected to the fixed frame 240. The bearing seat 210 is fixedly connected to the fixed frame 240, and the plurality of fasteners 241 are all passed through the fixed frame 240 and threadedly connected to the slide 120, so that the fasteners 241 can fix the fixed frame 240 on the slide 120, thereby stabilizing the position of the rotating mechanism 200.

[0038] The fastener 241 is threadedly connected to the slide 120. By driving the fastener 241 to rotate, the fastener 241 can be screwed into or out of the fixed frame 240, thereby allowing the fixed frame 240 to move closer to or further away from the slide 120. With the cooperation of multiple fasteners 241, the position of the fixed frame 240 can be easily adjusted, thereby driving the rotating shaft 220 to move, keeping the rotating shaft 220 horizontal, ensuring the accurate position of the detector 310, and improving the accuracy of the shooting.

[0039] It should be noted that multiple fasteners 241 are arranged at intervals along the circumference of the fixing frame 240. By adjusting the position of each fastener 241, the position of the fixing frame 240 can be flexibly adjusted, so that the rotating shaft 220 can remain horizontal. The fasteners 241 can be bolts, screws, etc., which will not be described in detail here.

[0040] Understandably, referring to Figure 2 and Figure 5 Multiple stiffening plates 221 connect the rotating shaft 220 to the mounting frame 300, and these stiffening plates 221 are arranged at intervals along the circumference of the rotating shaft 220. The stiffening plates 221 enhance the connection strength between the rotating shaft 220 and the mounting frame 300, making the connection more stable. This allows the rotating shaft 220 to withstand various loads generated by the mounting frame 300 and the detector 310, preventing loosening and deformation due to insufficient strength at the connection point. This ensures the stability of the detector 310's position and improves the quality of the captured images.

[0041] Understandably, referring to Figure 1 , Figure 3 and Figure 4The column 110 has guide grooves 111 on both sides, and the slide 120 has a first bearing 121 and a second bearing 122 on both sides. The axis of the first bearing 121 and the axis of the second bearing 122 are arranged perpendicularly. The first bearing 121 abuts against the side wall of the guide groove 111, and the second bearing 122 abuts against the bottom wall of the guide groove 111. Guide grooves 111 are provided on both sides of the column 110, and first bearings 121 and second bearings 122 are provided on both sides of the slide 120. The first bearings 121 and second bearings 122 are arranged in the guide grooves 111. By setting the first bearings 121 to abut against the side wall of the guide groove 111 and the second bearings 122 to abut against the bottom wall of the guide groove 111, the first bearings 121 and second bearings 122 can cooperate to limit the position of the slide 120 on the column 110. This not only enables the slide 120 to move accurately, but also reduces the resistance of the slide 120 on the column 110, thereby stabilizing the position of the rotating shaft 220 and improving the imaging accuracy of the detector 310.

[0042] It should be noted that the slide 120 is provided with multiple first bearings 121 and multiple second bearings 122 on the same side. The multiple first bearings 121 are arranged in two groups. One group of first bearings 121 abuts against one side wall of the guide groove 111, and the other group of first bearings 121 abuts against the other side wall of the guide groove 111. This can limit the slide 120 to the column 110, prevent the slide 120 from shifting position, and improve the positional stability of the slide 120.

[0043] Understandably, referring to Figure 3 and Figure 5 The system also includes a controller, a first detection component 410, and a second detection component 420. The first detection component 410 detects the position of the carriage 120, and the second detection component 420 detects the position of the rotating shaft 220. The first detection component 410 and the first drive member, as well as the second detection component 420 and the second drive member 230, are all electrically connected to the controller. The first detection component 410 is arranged on the lifting mechanism 100, and the second detection component 420 is arranged on the rotating mechanism 200. The first detection component 410 can detect the position of the carriage 120, and the second detection component 420 can detect the position of the rotating shaft 220, so that the controller can control the movement of the first drive member or the second drive member 230 respectively. This ensures accurate movement of the carriage 120 and the rotating shaft 220, improves the accuracy of the detector 310's position adjustment, and helps improve the imaging quality of the detector 310.

[0044] It should be noted that the controller can be a microcontroller, a programmable logic controller, an industrial computer, etc., which will not be elaborated here.

[0045] Specifically, refer to Figure 3The first detection component 410 includes two first triggers 411 and two first sensors 412. The two first triggers 411 are respectively arranged at both ends of the slide 120, and the two first sensors 412 are respectively arranged at both ends of the column 110. The first triggers 411 can trigger the first sensors 412, and the first sensors 412 are electrically connected to the controller. When the slide 120 slides on the column 110, the first triggers 411 can trigger the first sensors 412, thereby detecting the position of the slide 120 on the column 110. This allows the controller to control the first drive component to open or close, ensuring accurate movement of the slide 120, preventing the slide 120 from sliding off the column 110, reducing the possibility of positional deviation of the slide 120, and improving movement stability.

[0046] It should be noted that the first sensing element 412 can be a limit switch, an infrared sensor, an ultrasonic sensor, etc., so that the first triggering element 411 can trigger the first sensing element 412. These will not be described in detail here.

[0047] Specifically, refer to Figure 3 The first detection component 410 also includes two second triggers 413 and two second sensors 414. The two second triggers 413 are respectively arranged at both ends of the carriage 120. The second sensors 414 are arranged adjacent to the first sensors 412. The two second sensors 414 are respectively arranged at both ends of the column 110. The second triggers 413 can trigger the second sensors 414. The second sensors 414 are electrically connected to the controller. Two second triggers 413 are respectively arranged at both ends of the carriage 120, and two second sensors 414 are respectively arranged at both ends of the column 110. When the carriage 120 slides on the column 110, the second triggers 413 can trigger the second sensors 414, thereby detecting the position of the carriage 120 on the column 110. Moreover, the second sensors 414 and the first triggers 411 are arranged adjacent to each other, so that the first sensors 412 and the second sensors 414 form a dual position detection, so that the controller can accurately control the opening or closing of the first drive member. This not only improves the safety of the carriage 120 movement, but also improves the accuracy of the carriage 120 position control, which helps to improve the reliability of the device.

[0048] It should be noted that the second sensing element 414 can be a limit switch, an infrared sensor, an ultrasonic sensor, etc., so that the second triggering element 413 can trigger the second sensing element 414. These will not be described in detail here.

[0049] Specifically, refer to Figure 5 and Figure 6The second detection component 420 includes an encoder 421, a first gear 422, and a second gear 423. The first gear 422 is connected to the movable end of the encoder 421, and the second gear 423 is fixedly connected to the rotating shaft 220. The first gear 422 and the second gear 423 mesh. The encoder 421 is electrically connected to the controller. The first gear 422 is fixedly connected to the movable end of the encoder 421, and the second gear 423 is fixedly connected to the rotating shaft 220. By setting the first gear 422 and the second gear 423 to mesh, the rotation angle of the rotating shaft 220 can be transmitted to the encoder 421 sequentially through the second gear 423 and the first gear 422 to detect the rotation angle of the rotating shaft 220. This facilitates the controller to control the opening or closing of the second drive component 230, achieving precise control of the rotation angle of the rotating shaft 220 and improving the motion stability of the rotating shaft 220.

[0050] Specifically, refer to Figure 5 and Figure 6 The second detection component 420 also includes a light-shielding plate 424 and multiple detection elements 425. The light-shielding plate 424 is fixedly connected to the rotating shaft 220, and the multiple detection elements 425 are arranged at intervals along the circumference of the bearing seat 210. The light-shielding plate 424 can trigger the detection elements 425, and the detection elements 425 are electrically connected to the controller. The light-shielding plate 424 is fixedly connected to the rotating shaft 220, and the multiple detection elements 425 are arranged at intervals along the circumference of the bearing seat 210 so that when the rotating shaft 220 rotates, the light-shielding plate 424 can trigger the detection elements 425, thereby enabling the detection elements 425 to detect the position of the rotating shaft 220. This allows the controller to control the second drive element 230 to open or close, improving the rotation accuracy of the rotating shaft 220. Furthermore, the encoder 421 and the detection elements 425 work together to form dual position detection, effectively preventing excessive rotation of the rotating shaft 220 from causing cable breakage and improving the reliability of the device.

[0051] It should be noted that the detection component 425 can be a photoelectric sensor, which is not limited here.

[0052] Understandably, referring to Figure 3 The lifting mechanism 100 also includes two limiting blocks 130, which are respectively arranged at both ends of the column 110. The slide 120 can abut against the limiting blocks 130. The two limiting blocks 130 are respectively arranged at both ends of the column 110. By setting the slide 120 to abut against the limiting blocks 130, the slide 120 can be limited between the two limiting blocks 130, thereby preventing the slide 120 from sliding out of the column 110 and improving the reliability of the lifting mechanism 100.

[0053] The limiting block 130 can be an elastic component such as a rubber component or a silicone component, so that the limiting block 130 can buffer and absorb the impact of the movement of the slide 120, reduce the possibility of collision damage to the slide 120, and improve reliability.

[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
