Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0029] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention.

In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0030] In the field of large medical equipment, such as MRI and CT scanners, the stable operation of core components plays a crucial role in the overall performance and diagnostic accuracy of the equipment. Among these, rotating components (such as bearings, rotors, and related rotating parts) perform key mechanical functions during equipment operation.

[0031] In real-world maintenance scenarios, the lack of specialized auxiliary tooling presents numerous challenges for on-site maintenance operations. Large rotating components are typically complex in design, heavy, and equipped with multiple maintenance parts (such as sensors, coils, and counterweights). These parts are arranged circumferentially around the rotating component to ensure dynamic balance during operation. During maintenance, some of these parts may be located in the high areas of the rotating component, requiring maintenance personnel to use ladders or aerial work platforms, which increases the complexity and safety risks. More importantly, when disassembling certain maintenance parts, the center of gravity of the rotating component may shift, causing it to lose balance and potentially rotate unexpectedly. Such unexpected rotation can not only damage delicate internal components but also pose a safety threat to maintenance personnel. For example, during the maintenance of a CT scanner, if heavy components located on the upper part of the rotating component are disassembled without effective securing measures, the component may suddenly rotate due to imbalance, leading to equipment damage or personnel injury. Furthermore, the lack of specialized tooling can prolong maintenance time, reduce efficiency, and consequently affect the normal use of medical equipment.

[0032] In some maintenance scenarios, manual operation or simple fixing tools (such as temporary clamping devices) are used to address the balance issues of rotating components. However, these methods often have limited effectiveness and cannot be adapted to large medical equipment of different models and specifications. For example, manually adjusting the position of rotating components requires the cooperation of multiple people, which is time-consuming, labor-intensive, and difficult to guarantee accuracy. Simple fixing tools may not be able to withstand the weight or complex forces of rotating components, posing a risk of failure.

[0033] Please see Figure 1-3 , Figure 1 The present invention provides a maintenance system for medical equipment having a rotating component 1, comprising a drive unit 10, a locking unit 20, an interaction unit 30, and a control unit 40.

[0034] The drive unit 10 is connected to the rotating component 1 for driving the rotating component 1 (such as the rotor of an MRI or CT device) to a preset position. The preset position refers to rotating the part 3 to be maintained to a position convenient for maintenance personnel to operate, typically a horizontal or low-lying area, to reduce the need for working at height. For example, such as... Figure 2As shown, if a certain maintenance part 3 on the rotating component 1 is located at a high position, the drive unit 10 can rotate the rotating component 1 to a position where the maintenance part 3 can be easily accessed via a motor or other drive mechanism, reducing the difficulty of operation. If there are multiple maintenance parts 3, the drive unit 10 can rotate sequentially to different preset positions to achieve maintenance one by one. In this embodiment, the drive unit 10 can be a servo motor, a stepper motor, a hydraulic drive system, etc. In this embodiment, the transmission system between the drive unit 10 and the rotating component 1 can be a gear transmission mechanism, a belt transmission mechanism, a chain transmission mechanism, etc. The maintenance part 3 has a maintenance component 2 to be maintained, and the maintenance part 3 represents the location of the next maintenance component 2 that needs to be disassembled and maintained.

[0035] The locking unit 20 is connected to the rotating component (either directly or indirectly via electromagnetic force) to lock the rotating component 1 after it reaches a preset position, preventing accidental rotation due to imbalance or external forces. The locking unit 20 can employ a mechanical locking device (such as a clamping mechanism) or an electromagnetic locking mechanism to ensure the stability of the rotating component 1 during maintenance. For example, when disassembling heavy maintenance components 2, the locking unit 20 can effectively prevent the rotating component 1 from rotating due to imbalance, thereby ensuring the safety of equipment and personnel. The locking unit 20 can be controlled by the control unit 40 or manually by the operator.

[0036] The interaction unit 30 provides an operating interface for maintenance personnel, used to receive user input commands and output command information. In this embodiment, the interaction unit 30 can be a touch screen, a button panel, or a remote control terminal, allowing maintenance personnel to input commands such as the rotation angle of the rotating component 1 and locking requirements through simple operations. For example, maintenance personnel can use the interaction unit 30 to set the rotating component 1 to rotate to a specific angle (such as 0° or 90°) or preset maintenance positions for each component, so as to facilitate the maintenance of specific components.

[0037] The control unit 40, as the core of the maintenance system, is responsible for receiving the instruction information and coordinating the work of the drive unit 10 and the locking unit 20. The control unit 40, through a preset program or algorithm, controls the rotation angle and speed of the drive unit 10, as well as the locking / unlocking action of the locking unit 20, based on the instruction information, ensuring the entire maintenance process is precise and efficient. For example, when maintenance personnel input the instruction "rotate the rotating part 1 by 90° and lock" through the interaction unit 30, the control unit 40 will command the drive unit 10 to complete the rotation action and trigger the locking unit 20 to fix the rotating part 1.

[0038] In the above scheme, taking the maintenance of the rotating component 1 of a CT scanner as an example, the rotating component 1 typically includes maintenance components 2 such as an X-ray tube, a detector, and a counterweight, distributed circumferentially. Assume that the X-ray tube located at the top of the rotating component 1 needs to be replaced. Using the maintenance system of this utility model, the maintenance process is as follows:

[0039] Maintenance personnel can input commands through the interactive unit 30 (such as a touch screen) to specify that the position of the X-ray tube be rotated to the lowest point (preset position).

[0040] The control unit 40 receives the command, the drive unit 10 starts, and drives the rotating part 1 to rotate to a horizontal position, so that maintenance personnel can operate directly.

[0041] After the rotating component 1 reaches the preset position, the locking unit 20 is automatically activated, and the rotating component 1 is fixed by a mechanical or electromagnetic locking mechanism to prevent rotation caused by the imbalance of the center of gravity due to the disassembly of the X-ray tube.

[0042] After the maintenance personnel complete the replacement of the X-ray tube, they input the next instruction through the interaction unit 30, and the drive unit 10 rotates the next part to be maintained 3 (such as the detector) to the preset position, and repeats the above process.

[0043] The entire process requires no high-altitude work or multi-person collaboration, and is simple, safe, and efficient. If there are multiple parts 3 to be maintained on the rotating component 1, the maintenance system can rotate each component sequentially to a suitable maintenance position to complete all maintenance tasks. This intelligent and automated maintenance method not only improves efficiency but also significantly reduces safety risks, ensuring the stable operation and diagnostic accuracy of the CT scanner.

[0044] Similarly, in MRI equipment, the maintenance system can be used to maintain the coils or sensors on the magnet rotating part 1. Through precise positioning and stable locking, it ensures that the uniformity of the magnetic field is not affected during the maintenance process, providing a reliable guarantee for the efficient operation of the equipment.

[0045] In one embodiment of this utility model, the locking unit 20 can control the current of the drive motor of the rotating component 1 to lock the rotating component 1. The locking unit 20 achieves the locking function of the rotating component 1 by controlling the current of the drive motor of the rotating component 1. Specifically, the locking unit 20 is integrated with the control system of the drive motor. By precisely adjusting the current input of the motor (e.g., by applying a specific amount of holding current or reverse current), the motor generates sufficient electromagnetic force or resistance to fix the rotating component 1 in a preset position and prevent it from rotating accidentally. This locking method utilizes the electromagnetic characteristics of the drive motor itself, eliminating the need for additional mechanical locking devices, simplifying the structure, and improving the reliability and response speed of the locking. In actual operation, when the rotating component 1 is rotated to a preset position (e.g., a horizontal position convenient for maintenance personnel to operate) by the drive unit 10, the control unit 40 sends a command to the locking unit 20. The locking unit 20 then adjusts the current of the drive motor to put the motor in a "locked state". For example, by applying a constant holding current, the motor can maintain a certain fixed angle to resist the rotation tendency caused by imbalance of the center of gravity or external forces. In addition, this current control method can achieve dynamic adjustment to adapt to the locking requirements under different load conditions, ensuring the stability of rotating part 1 during maintenance.

[0046] In one embodiment of this utility model, the locking unit 20 is a mechanical locking structure. The mechanical locking structure achieves its locking function through a physical mechanism (such as a locking pin, clamping device, or buckle), making it particularly suitable for scenarios where the medical device itself is powered off. Unlike electromagnetic locking methods that control the current of the drive motor, the mechanical locking structure does not rely on the power of the medical device itself, ensuring the stability of the rotating part 1 even when the device is completely powered off, thereby improving safety and reliability during maintenance. During operation, when the drive unit 10 rotates the rotating part 1 to a preset position (such as a horizontal position for easy operation by maintenance personnel), the control unit 40 triggers the separately powered mechanical locking structure (or a manually controlled mechanical locking structure). The physical constraint force of the mechanical locking structure fixes the rotating part 1, preventing accidental rotation due to gravity, unbalanced torque, or external forces (such as the pushing force during maintenance personnel operation). The independence of the mechanical locking structure is particularly important in power-off scenarios, as the medical device may require power disconnection during maintenance to ensure safety (such as avoiding electric shock or electromagnetic interference).

[0047] In one embodiment of this utility model, the drive unit 10 is independently configured relative to the drive motor of the rotating component 1. That is, the drive unit 10 is separate from the drive motor of the rotating component 1 used for normal operation in the medical device. During maintenance, medical devices often require power outages to ensure safety (e.g., to avoid electric shock or electromagnetic interference). If the drive unit 10 relies on the drive motor, it cannot drive the rotating component 1 to a preset position (e.g., a horizontal position convenient for maintenance) after a power outage. The independently configured drive unit 10 is powered by an independent power supply and can continue to operate when the device is powered off, ensuring the smooth progress of the maintenance process. The drive motor is typically designed for medical device operation (e.g., CT scans or MRI imaging), optimized for high-speed rotation or specific operating modes, and lacks the ability to precisely control the rotation angle and speed. However, during maintenance, the rotating component 1 needs to rotate to a specific position (e.g., a positioning accuracy of ±0.1°) at a low speed and with precision. The independent drive unit 10 (e.g., a servo motor or stepper motor) is specifically designed for maintenance needs, equipped with a high-precision encoder or feedback device, enabling precise rotation control and meeting the special requirements of maintenance scenarios.

[0048] In one embodiment of this utility model, the control unit 40 can control the drive unit 10 to drive the rotating component 1 to rotate to different preset positions according to different instructions. This design ensures that the rotating component 1 (such as the rotor of a CT scanner, the magnet rotating component 1 of an MRI, or the rotating gantry of a radiotherapy device) can be positioned at a specific angle or position required for maintenance in a high-precision and flexible manner. The control unit 40 receives user input instructions from the interaction unit 30 (such as a portable control panel, touch screen, or computer interface). The instructions typically include the target position (such as rotating 90°, 180°, or a specific angle), the required rotation speed, or the type of maintenance task. The control unit 40 parses the instructions and, combined with the current state of the rotating component 1 (such as the current position fed back by an encoder or sensor), calculates the required rotation angle, direction, and speed. The control unit 40 sends precise electrical signals to the drive unit 10 (such as a servo motor or stepper motor) to control the motor's speed and rotation angle, so that the rotating component 1 rotates smoothly to the preset position. The control unit 40 monitors the position of the rotating component 1 in real time through sensors (such as a high-precision encoder or limit switch) and adjusts the output of the drive unit 10 to ensure positioning accuracy. After the rotating part 1 reaches the preset position, the control unit 40 triggers the locking unit 20 (such as a mechanical locking pin or an electromagnetic locking device) to fix the rotating part 1 and prevent accidental rotation.

[0049] In one embodiment of this utility model, the control unit 40 can control the drive unit 10 to drive the rotating member 1 to rotate, thereby rotating the part 3 to be maintained on the rotating member 1 to the lowest position (e.g., Figure 3As shown, the control unit 40 controls the locking unit 20 to lock the rotating part 1 at the six o'clock position. The control unit 40 receives instructions input by maintenance personnel through the interaction unit 30 (such as a touch screen or portable control panel), such as "rotate the X-ray tube to the six o'clock position". The instructions include the identification of the part 3 to be maintained (such as "X-ray tube") or a specific angle (180°, corresponding to the lowest position). The control unit 40 calculates the rotation angle and direction based on the current position of the rotating part 1 (via encoder or sensor feedback), generates a control signal, and drives the motor of the independent drive unit 10 (such as a servo motor or stepper motor) to rotate the rotating part 1 to the six o'clock position at a low speed and in a precise manner. The control unit 40 uses a high-precision encoder or limit switch to monitor the angle of the rotating part 1 in real time to ensure positioning accuracy, so that the part 3 to be maintained accurately reaches the lowest position, facilitating maintenance operations. Once the rotating part 1 reaches the six o'clock position, the control unit 40 immediately triggers the locking unit 20 (such as a mechanical locking pin or clamping device) to fix the rotating part 1 by physical constraint force, preventing accidental rotation caused by imbalance of center of gravity or external force (such as the thrust when disassembling parts).

[0050] In one embodiment of this utility model, a noise detection unit 50 is further included, which is communicatively connected to the control unit 40. The noise detection unit 50 is used to detect the noise when the rotating component 1 rotates. The noise detection unit 50 aims to monitor the operating status of the rotating component 1 through noise characteristics, identify potential mechanical faults or abnormalities (such as bearing wear, poor gear meshing, or loose parts), thereby improving the maintenance efficiency and operational reliability of the medical equipment. In addition, the maintenance system also includes a storage unit 60, which records the noise data collected by the noise detection unit 50 and its corresponding rotational speed of the rotating component 1. The data can be uploaded to a cloud server for further analysis to support predictive maintenance and remote diagnostics.

[0051] Specifically, a noise detection unit 50 (such as a high-sensitivity microphone or vibration sensor) is installed near the rotating component 1 to collect sound waves or vibration signals generated by the rotating component 1 during operation or maintenance in real time. The detection frequency range typically covers the typical frequency band of mechanical noise and can capture abnormal noise (such as sharp metallic friction sounds or low-frequency vibrations). The noise detection unit 50 correlates the collected noise data (including noise intensity, frequency distribution, etc.) with the rotational speed of the rotating component 1 (feedback from the encoder or control unit 40) and transmits it to the control unit 40. The control unit 40 stores this information in a storage unit 60 (such as an embedded flash memory or SD card). The noise data and rotational speed information in the storage unit 60 can be uploaded to a cloud server via a network interface (such as Wi-Fi or Ethernet). The cloud server uses algorithms to analyze noise characteristics, identify abnormal patterns, determine the health status of the rotating component 1, and generate maintenance suggestions.

[0052] In one embodiment of this utility model, the control unit 40 can control the rotation of the rotating component 1 (either by the drive unit 10 or by the drive motor of the rotating component 1 itself), and detect the noise during the rotation of the rotating component 1 through the noise detection unit 50. This design adds the function of automatically starting the detection mode when the medical device is not in operation (such as standby or maintenance mode), so as to avoid interference from medical staff, patients or other environmental sounds during the operation of the medical device, thereby ensuring the accuracy of noise data and improving the reliability of fault diagnosis and maintenance efficiency. The driving of the rotating component 1 can be achieved by the drive unit 10 (such as an independent servo motor or stepper motor) or the drive motor built into the rotating component 1, and the control unit 40 coordinates the two to achieve precise rotation and noise monitoring.

[0053] In one embodiment of this utility model, the control unit 40 can control the rotating component 1 to rotate at different speeds (it can be driven by the drive unit 10 or by the drive motor of the rotating component 1 itself). By precisely adjusting the speed, the control unit 40 can meet the needs of different scenarios (such as daily operation, maintenance and inspection, or autonomous inspection mode), and in conjunction with the noise detection unit 50 and the storage unit 60, it can realize real-time monitoring and fault diagnosis of the operating status of the rotating component 1, thereby improving the operational reliability, maintenance efficiency, and safety of the medical equipment.

[0054] This utility model also provides a medical device, which may specifically be a CT scanner (computed tomography scanner), magnetic resonance imaging (MR) equipment, etc. The medical device includes the maintenance system and a rotating component 1 connected to the maintenance system during maintenance. The rotating component 1 may specifically be a rotating support structure for some MRI equipment, a rotating gantry for a CT scanner, etc.

[0055] In summary, this invention, through the collaborative design of the drive unit 10, locking unit 20, interaction unit 30, and control unit 40, achieves intelligent maintenance management of the rotating component 1 of the medical device. The maintenance system can precisely drive the rotating component 1 to a preset position (such as a low-lying area for easy operation) and ensure stable locking of the rotating component 1 through mechanical or electrical locking mechanisms. This effectively solves the risk of accidental rotation caused by center of gravity shift during component disassembly, significantly reducing the need for high-altitude operations and operational safety hazards. Simultaneously, it supports multi-position automatic cyclic positioning, adapting to the maintenance components 2 distributed around the rotating component 1, improving maintenance efficiency. The independent drive unit 10 design ensures operational feasibility in power outage scenarios, and the noise detection unit 50, combined with cloud analysis, enables fault warning and predictive maintenance. The overall solution improves the operational reliability of the medical device, reduces maintenance complexity, and provides standardized and highly safe technical guarantees for the maintenance of the rotating component 1.

Furthermore, although the accompanying drawings of this application show unidirectional arrows, as those skilled in the art will understand, in specific applications, any one or more, or all, of these unidirectional arrows can be adjusted to bidirectional arrows, and can be adjusted according to the function and role of the control unit 40.
