Description

Technical Field

[0001] This application relates to the field of fault detection technology, and in particular to a sensor transfer device, a fault monitoring system, and a mechanical system. Background Technology

[0002] Mechanical equipment failures can cause significant economic losses and personal safety risks. Therefore, it is crucial to monitor the status of mechanical equipment in real time and to promptly detect and resolve any malfunctions.

[0003] To facilitate timely detection and troubleshooting, sensors are typically installed on mechanical equipment for detection, and fault diagnosis is then performed based on the detection results.

[0004] Because sensors are expensive, in order to save costs, sensors are usually only installed on a few key vulnerable parts of mechanical equipment. In this case, the number of sensors is small, the comprehensiveness and accuracy of fault monitoring are poor, and it is easy to miss or misdiagnose, resulting in significant economic losses and safety hazards.

[0005] The above statements are for the purpose of providing background information in relation to this application only, and do not necessarily constitute prior art. Utility Model Content

[0066] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0067] In the description of this application, the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0068] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0069] In this application, "multiple (levels)" means at least two (levels), that is, two (levels), three (levels), four (levels) or more (levels).

[0070] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0071] Structural components of mechanical equipment, such as engines, reducers, and drive shafts of engineering vehicles and other construction machinery, may malfunction during operation. If these malfunctions are not detected and addressed in a timely manner, they may cause significant economic losses and lead to major safety accidents. Therefore, it is crucial to monitor mechanical equipment in real time and detect and eliminate malfunctions promptly.

[0072] Using sensors for detection is a common fault monitoring method. Typically, multiple sensors are installed on mechanical equipment, each detecting different parts, and fault diagnosis is performed based on the detection results. In this case, each sensor is fixed in one location, detecting only one part. Because sensors are usually expensive, to save costs, sensors are often only placed on a few key, vulnerable parts of the mechanical equipment. The number of sensors is small, and the cost is low. However, this results in limited detection data, poor detection comprehensiveness, and affects the accuracy of fault diagnosis, easily leading to missed or misdiagnosed cases, causing significant economic losses and safety hazards.

[0073] While increasing the number of sensors can improve the comprehensiveness and accuracy of detection and reduce the risk of missed or misdiagnosed cases, deploying a large number of sensors will significantly increase costs.

[0074] It is evident that deploying only a limited number of sensors results in poor detection comprehensiveness, affecting the accuracy of fault diagnosis and easily leading to missed or misdiagnosed cases, causing significant economic losses and safety hazards. Conversely, deploying more sensors increases costs. Therefore, how to achieve more comprehensive fault monitoring with a smaller number of sensors and reduce the risk of missed or misdiagnosed cases has become an urgent problem to be solved.

[0075] In view of the above situation, this application provides a sensor transfer device.

[0076] Figures 1-11 The structure of the sensor transfer device of this application is illustrated by way of example.

[0077] See Figures 1-11 In this application, the sensor transfer device 10 includes a connector 1 and a drive mechanism 2. The connector 1 includes a connecting member 11 for detachably engaging with a sensor 30. The drive mechanism 2 is driven to connect with the connector 1 and drives the connector 1 closer to or further away from the sensor 30 and moves the engaged sensor 30 to change the position of the sensor 30, allowing the sensor 30 to detect different parts of the mechanical equipment.

[0078] Because of the cooperation between connector 1 and drive mechanism 2, sensor transfer device 10 can engage with sensor 30 and move the engaged sensor 30 to other positions for detection. Therefore, the position of sensor 30 is no longer fixed, and sensor 30 can no longer only detect one part. Instead, it can flexibly change position and switch detection points under the action of sensor transfer device 10. In this case, during the operation of mechanical equipment, the position of sensor 30 can be flexibly changed by sensor transfer device 10 according to actual needs, increasing detection data and improving detection comprehensiveness. This allows for improved comprehensiveness and accuracy of fault monitoring without increasing the number of sensors 30, thereby effectively reducing the risk of missed or misdiagnosed cases based on a smaller number of sensors and lower cost.

[0079] During operation, if a certain part of the mechanical equipment requires it, the sensor transfer device 10 can send the sensor 30, which was originally placed in other parts, to the corresponding part for detection. This allows even parts where the sensor 30 was not originally placed to be effectively detected. In this case, only a few sensors 30 need to be placed to detect more parts, providing as many feature signals as possible, and achieving more comprehensive and accurate detection and diagnosis.

[0080] As can be seen, the sensor transfer device 10 can switch detection points by flexibly changing the position of the sensor 30, thereby improving the comprehensiveness of detection. In this way, the problem of missed diagnosis and misdiagnosis caused by insufficient number of sensors can be effectively solved. With only a few sensors 30 and a low cost, the comprehensiveness and accuracy of fault monitoring can be effectively improved, and the risk of missed diagnosis and misdiagnosis can be reduced.

[0081] The motion of the connector 1 of the sensor transfer device 10 can be varied, including rotation and / or movement.

[0082] As an example, see Figures 1-11 The drive mechanism 2 drives the connector 1 to move along at least one of a first direction X and a second direction Z, which are perpendicular to each other, to move the connector 1 closer to or away from the sensor 30 and to move the engaged sensor 30. In this case, the movement of the connector 1 is a movement along the first direction X and / or a second direction Y perpendicular to the first direction X. The connector 1 can move closer to or away from the sensor 30 accordingly, and can also move the engaged sensor 30 between different positions to switch detection points.

[0083] Based on the movement in the first direction X and / or the second direction Y, the connector 1 can move within a larger range, engage with the sensor 30 within a larger range, and drive the engaged sensor 30 to move within a larger range, realizing the switching of more detection points. Therefore, without increasing the number of sensors, the comprehensiveness and accuracy of fault diagnosis can be improved more effectively, and the risk of missed diagnosis and misdiagnosis can be reduced.

[0084] To achieve the movement of connector 1 along the first direction X, see [reference needed]. Figures 1-3 In some embodiments, the driving mechanism 2 includes a first driving mechanism 3, which drives the connector 1 to move along a first direction X. In this way, the connector 1 can automatically move along the first direction X under the action of the first driving mechanism 3, which is not only highly efficient but also accurate. This allows the connector 1 to move closer to and further away from the sensor 30 more quickly and accurately, and to move the sensor 30 between different detection points, thus achieving a more efficient and comprehensive fault diagnosis process.

[0085] Specifically, see [link to relevant documentation] Figures 1-3 In some embodiments, the first driving mechanism 3 includes a guide 31 and a moving member 32. The guide 31 extends along a first direction X, and the moving member 32 can move along the guide 31 and is driven to connect with the connector 1 to drive the connector 1 to move along the first direction X. In this way, the connector 1 can be driven to move along the first direction X simply by the moving member 32 moving along the guide 31, which is simple and convenient.

[0086] More specifically, see Figure 1 and Figure 2 In some embodiments, the guide 31 includes a rack 33, and the moving member 32 includes a first gear 34, which meshes with the rack 33. Thus, only the rotation of the first gear 34 is needed to move along the rack 33, achieving movement along the first direction X. This not only results in a simple and compact structure but also efficient and accurate transmission, which helps reduce the space occupied by the sensor transfer device 10 and improves the efficiency and accuracy of detection point switching.

[0087] Additionally, to achieve the movement of connector 1 along the second direction Y, see [link to relevant documentation]. Figures 1-11 In some embodiments, the drive mechanism 2 includes a second drive mechanism 4, which drives the connector 1 to move along the second direction Z. Thus, under the action of the second drive mechanism 4, the connector 1 can automatically move along the first direction X, which is not only highly efficient but also accurate. This allows the connector 1 to move closer to and further away from the sensor 30 more quickly and accurately, and to move the sensor 30 between different detection points, achieving a more efficient and comprehensive fault diagnosis process.

[0088] Specifically, see Figure 1 and Figure 2 In some embodiments, the second driving mechanism 4 includes a first driving member 5 and a second driving member 6. The first driving member 5 and the second driving member 6 respectively drive the connector 1 to move towards a first side and a second side in the second direction Z, so that the connector 1 moves along the second direction Z. In this way, the connector 1 can reciprocate along the second direction Z, and the reciprocating movement of the connector 1 along the second direction Z is carried out under the drive of the first driving member 5 and the second driving member 6 respectively. Since the movement of the connector 1 along both sides of the second direction Z is driven by dedicated components, it is more conducive to improving the accuracy of movement.

[0089] Further, see Figures 1-11 In some embodiments, the second drive mechanism 4 includes not only the first drive member 5 and the second drive member 6, but also a receiving member 7. The connector 1 is movably disposed in the receiving member 7 along the second direction Z. The first drive member 5 is openably disposed in the end opening 723 of the receiving member 7. When closed, it applies a force to the connector 1 toward the first side of the second direction Z to drive the connector 1 to move toward the first side of the second direction Z into the receiving member 7. When open, it avoids the connector 1. The second drive member 6 is disposed in the receiving member 7 and applies a force to the connector 1 toward the second side of the second direction Z to drive the connector 1 to move toward the second side of the second direction Z when the first drive member 5 is open, so that the connector 11 extends to the outside of the end opening 723.

[0090] Based on the above configuration, connector 1 can not only reciprocate along the second direction Z under the drive of the first driving member 5 and the second driving member 6, but also extend out of the receiving member 7 or retract into the receiving member 7 during the reciprocating movement along the second direction Z. In this way, on the one hand, when it is necessary to switch the detection point, connector 1 can extend out of the receiving member 7 under the action of the second driving member 6, which facilitates the connection between connector 1 and sensor 30; on the other hand, when the detection point is switched, connector 1 can retract into the receiving member 7 under the action of the first driving member 5. In this way, connector 1 can be protected by the first driving member 5 and the receiving member 7, which can protect it from dust, rain and impact, improve reliability and extend service life. Moreover, the size of sensor transfer device 10 can be reduced, the space occupied by sensor transfer device 10 can be reduced, and the impact on the original layout of mechanical equipment can be minimized while improving the comprehensiveness and accuracy of fault monitoring.

[0091] The first driving component 5 and the second driving component 6 can adopt various structural forms.

[0092] For example, see Figure 2 In some embodiments, the second driving member 6 includes an elastic component such as a spring 61. Thus, the second driving member 6 only needs to abut against the connector 1 on the side of the connector 11 away from the end opening 723 to apply an elastic force to the connector 1 towards the second side of the second direction Z. This allows the connector 1 to move towards the second side of the second direction Z under the action of the corresponding elastic force when the first driving member 5 is open, extending beyond the end opening 723 and connecting with the sensor 30. Furthermore, when the first driving member 5 is closed and a force is applied to the connector 1 towards the first side of the second direction Z, the second driving member 6 can retract accordingly, without hindering the movement of the connector 1 towards the first side of the second direction Z, facilitating the smooth retraction of the connector 1 into the receiving member 7. Moreover, when the second driving member 6 includes an elastic component such as a spring 61, the cost is lower, the space occupied is smaller, and the structural compactness of the sensor transfer device 10 is improved.

[0093] For example, see Figure 6 and Figure 7 In some embodiments, the first driving member 5 includes two covers 51, which are arranged opposite to each other along the opening and closing direction of the first driving member 5 and can move closer or further away from each other to open and close the first driving member 5. Based on this, simply moving the two covers 51 closer or further away from each other is sufficient to control the opening and closing of the first driving member 5, which is simple and convenient. Since the driving force required for each cover 51 is smaller when driving the first driving member 5 to open and close by driving the entire first driving member 5, compared to driving the entire first driving member 5 to open and close, it is more labor-saving and efficient.

[0094] The cover 51 can move as a whole to move closer to or further away from another cover 51, or it can move partially to move closer to or further away from another cover 51. In addition, the cover 51 can move closer to or further away from another cover 51 by rotating and / or moving.

[0095] For example, see Figure 6 and Figure 7 In some embodiments, the cover 51 includes multiple cover plates 52, which are connected sequentially along the opening and closing direction and can move relative to each other along the opening and closing direction to move the cover 51 closer to or further away from another cover 51. Based on this, the cover 51 can extend and retract through the relative movement of the multiple cover plates 52. In this case, the cover 51 does not need to move as a whole relative to the receiving member 7, but only some of the cover plates 52 need to move to move closer to or further away from another cover 51 to control the opening and closing of the first driving member 5. When opened, it occupies less space, which not only improves the structural compactness, but also reduces the risk of interference with the structural components of mechanical equipment during the opening and closing process, making the operation safer and more reliable.

[0096] Further, see Figure 7 In some embodiments, the cover 51 includes not only multiple cover plates 52, but also a reset member 53. The reset member 53 connects two adjacent cover plates 52 and applies a force to the adjacent cover plates 52 to move them away from each other. Based on this, after the external force is released, the multiple cover plates 52 of the cover 51 can automatically move away from each other under the action of the reset member 53, causing the cover 51 to reset and return to a position closer to another cover 51, thus closing the first driving member 5. This makes the closing process of the first driving member 5 more efficient and effortless. Exemplarily, the reset member 53 includes an elastic component such as a spring 61 to facilitate the closing of the first driving member 5 without hindering its opening.

[0097] The opening and closing of the first driving component 5 can have multiple driving methods. As one example, see... Figures 1-11 In some embodiments, the first driving member 5 is driven to connect with the receiving member 7 and opens and closes under the drive of the receiving member 7. In this way, the receiving member 7 is not only used to receive the connector 1, but also to drive the first driving member 5 to open and close, which makes the function richer and the degree of integration higher. Compared with the method of setting up a separate component to drive the first driving member 5 to open and close, it is more conducive to simplifying the structure and reducing space occupation.

[0098] As an example of the receiving member 7 that drives the opening and closing of the first driving member 5, see Figures 1-11In some embodiments, the receiving member 7 includes a multi-stage sleeve 71, which is sequentially sleeved along the second direction Z and can move relative to each other along the second direction Z. The multi-stage sleeve 71 includes a final stage sleeve 72, with an end opening 723 located on the final stage sleeve 72. The connector 1 is movably disposed in the final stage sleeve 72 along the second direction Z. The final stage sleeve 72 is driven to connect with the first driving member 5 and drives the first driving member 5 to open and close by moving along the second direction Z.

[0099] Based on the above configuration, the receiving member 7 can extend and retract by the relative movement of the multi-stage sleeves 71 arranged in sequence along the second direction Z. This helps to further reduce the volume of the sensor transfer device 10 and reduce the space occupied by the sensor transfer device 10 without the need to switch detection points. Furthermore, the receiving member 7 can drive the first driving member 5 to open and close by moving the last stage cylinder 72 along the second direction Z, thereby controlling the first driving member 5 to apply or release the force on the connector 1, which is simple and convenient.

[0100] Specifically, in order to achieve the driving connection between the final stage cylinder 72 and the first driving member 5, so that the final stage cylinder 72 can drive the first driving member 5 to open and close by moving along the second direction Z, see [reference needed]. Figures 1-11 In some embodiments, the second drive mechanism 4 includes a linkage mechanism 81, which includes a roller 82 and a pulling member 83. The roller 82 is disposed on the final stage cylinder 72. The first end of the pulling member 83 is fixed, and the second end passes around the roller 82 and is connected to the first drive member 5 to realize the drive connection between the final stage cylinder 72 and the first drive member 5.

[0101] Based on the above configuration, the final stage cylinder 72 is driven to connect with the first driving member 5 via the pulling member 83. When the final stage cylinder 72 moves along the second direction Z, the pulling member 83 can tighten or loosen accordingly. The second end of the pulling member 83 can pull or release the first driving member 5, thereby realizing the opening and closing of the first driving member 5. Specifically, see Figure 10 and Figure 11 When the final stage cylinder 72 moves towards the second side along the second direction Z, the pulling member 83 can be tightened, pulling the first driving member 5 and opening the first driving member 5; while when the final stage cylinder 72 moves towards the first side along the second direction Z, the pulling member 83 can be loosened, releasing the pull on the first driving member 5, making it convenient for the first driving member 5 to close again.

[0102] As can be seen, the linkage mechanism 81, which includes the pulling member 83 and the roller 82, can realize the driving connection between the final stage cylinder 72 and the first driving member 5, converting the reciprocating movement of the final stage cylinder 72 along the second direction Z into the opening and closing of the first driving member 5, which facilitates the control of whether the connector 1 extends outside the receiving member 7 and engages with the sensor 30. Since the pulling member 83 and the roller 82 occupy little space, it is beneficial to further reduce the space occupied by the sensor transfer device 10.

[0103] The form of the pulling member 83 is not limited; for example, it can be a rope or a chain, and correspondingly, the roller 82 can be a smooth wheel or a sprocket.

[0104] Furthermore, the number of linkage mechanisms 81 is unlimited; there can be one or more. For example, see... Figures 6-11 The second drive mechanism 4 includes two linkage mechanisms 81, which correspond one-to-one with the two covers 51 of the first drive member 5. The second ends of the pulling members 83 of the two linkage mechanisms 81 are respectively connected to the two covers 51, so that the final stage cylinder 72 can drive the two covers 51 to move closer or further apart by moving along the second direction Z. In this way, the two linkage mechanisms 81 can convert the movement of the final stage cylinder 72 along the second direction Z into the opposite movement of the two covers 51 along the opening and closing direction, thereby controlling the opening and closing of the first drive member 5.

[0105] In the foregoing embodiments, the movement of the final stage cylinder 72 along the second direction Z can be achieved by various methods. As one example, see [link to relevant documentation]. Figures 1-6 In some embodiments, the multi-stage sleeve 71 includes not only the final stage sleeve 72 but also a linkage sleeve 73. The linkage sleeve 73 is movably disposed along the second direction Z and is drivenly connected to the final stage sleeve 72 so that the final stage sleeve 72 is driven to move along the second direction Z by moving along the second direction Z. Based on this, only the movement of the linkage sleeve 73 along the second direction Z is needed to drive the final stage sleeve 72 to move along the second direction Z, which is simple and convenient. Using the linkage sleeve 73 in the multi-stage sleeve 71 to drive the movement of the final stage sleeve 72 results in a simpler structure and occupies less space.

[0106] To achieve the driving connection between the linkage cylinder 73 and the final stage cylinder 72, so that the linkage cylinder 73 can drive the final stage cylinder 72 to move together along the second direction Y, see [reference needed]. Figure 2 and Figure 5 In some embodiments, the second drive mechanism 4 includes not only the linkage cylinder 73, but also the actuation mechanism 84. The actuation mechanism 84 includes a rotating wheel 85 and a traction member 86. The rotating wheel 85 is disposed on the linkage cylinder 73. The first end of the traction member 86 is fixed, and the second end passes around the rotating wheel 85 and is connected to the final stage cylinder 72 to realize the drive connection between the linkage cylinder 73 and the final stage cylinder 72.

[0107] Based on the above configuration, the linkage cylinder 73 is driven to the final stage cylinder 72 via the traction member 86. When the linkage cylinder 73 moves along the second direction Z, the traction member 86 can be tightened or loosened accordingly. The second end of the traction member 86 can pull or release the final stage cylinder 72, causing the final stage cylinder 72 to move along the second direction Z. See details... Figure 2 and Figure 5When the linkage cylinder 73 moves towards the second side along the second direction Z, the traction member 86 can be tightened, pulling the final stage cylinder 72 and causing the final stage cylinder 72 to move towards the second side along the second direction Z; while when the linkage cylinder 73 moves towards the first side along the second direction Z, the traction member 86 can be released, releasing the pull on the final stage cylinder 72 and allowing the final stage cylinder 72 to move towards the second side along the second direction Z.

[0108] As can be seen, the actuation mechanism 84, which includes the traction member 86 and the rotating wheel 85, can realize the driving connection between the linkage cylinder 73 and the final stage cylinder 72, converting the movement of the linkage cylinder 73 along the second direction Z into the movement of the final stage cylinder 72 along the second direction Z. This facilitates the control of whether the first driving member 5 opens and closes, and thus controls whether the connector 1 extends outside the receiving member 7 to engage with the sensor 30. Since the traction member 86 and the rotating wheel 85 occupy relatively little space, this helps to further reduce the space occupied by the sensor transfer device 10.

[0109] The form of the traction member 86 is not limited; for example, it can be a rope or a chain, and correspondingly, the wheel 85 can be a smooth wheel or a sprocket.

[0110] Furthermore, the number of actuating mechanisms 84 is unlimited; there can be one or more. For example, see... Figure 2 and Figure 5 In some embodiments, the second drive mechanism 4 includes two actuation mechanisms 84, which are disposed on opposite sides of the final stage cylinder 72. Thus, the two actuation mechanisms 84 can apply force to opposite sides of the final stage cylinder 72, driving the final stage cylinder 72 to move more smoothly along the second direction Z, thereby controlling the first drive member 5 to open and close more smoothly.

[0111] See also Figure 2 and Figure 5 In some embodiments, the second drive mechanism 4 includes an elastic element 77 connected to the final stage cylinder 72 and applying an elastic force to the final stage cylinder 72 on a first side in the second direction Z. This facilitates the automatic return of the final stage cylinder 72 under the action of the elastic element 77.

[0112] In the foregoing embodiments, the driving method for the movement of the linkage cylinder 73 along the second direction Z can be varied. For example, see... Figures 1-5 In some embodiments, the multi-stage sleeve 71 includes not only the linkage cylinder 73 but also a rotating cylinder 74. The rotating cylinder 74 is rotatably disposed and threadedly connected to the linkage cylinder 73 so that the linkage cylinder 73 can be driven to move along the second direction Z by rotation. In this way, simply rotating the rotating cylinder 74 is enough to drive the linkage cylinder 73 to move along the second direction Z, which is simple and convenient. Using the rotating cylinder 74 in the multi-stage sleeve 71 to drive the movement of the linkage cylinder 73 results in a simpler structure and occupies less space.

[0113] Furthermore, in order to achieve the rotation of the rotating cylinder 74, see... Figure 2 In some embodiments, the second drive mechanism 4 includes not only the rotating cylinder 74, but also a transmission mechanism 87. The transmission mechanism 87 is drivenly connected to the rotating cylinder 74 to drive the rotating cylinder 74 to rotate. In this way, the rotating cylinder 74 can rotate automatically under the drive of the transmission mechanism 87, which is more efficient and accurate.

[0114] The transmission mechanism 87 can adopt various structural forms. For example, see... Figure 2 The transmission mechanism 87 includes a second gear 88 and a third gear 89. The second gear 88 is connected to the rotating cylinder 74 and meshes with the third gear 89 to drive the rotating cylinder 74 to rotate when the third gear 89 rotates.

[0115] The rotating cylinder 74 is driven to rotate by the meshing second gear 88 and third gear 89. This design is not only simple and compact, but also has high transmission efficiency and high transmission accuracy. It can achieve more efficient and precise rotation of the rotating cylinder 74 while reducing space occupation. This allows for more efficient and accurate control of the movement of the linkage cylinder 73 and the final stage cylinder 72, the opening and closing of the first driving component 5, and the movement of the connector 1. This enables the sensor transfer device 10 to connect or disconnect from the sensor 30 more efficiently and accurately, meeting the needs of more efficient, comprehensive and accurate fault monitoring.

[0116] In the case where the second drive mechanism 4 includes the receiving member 7, in order to accurately control the displacement of the connector 1, see [reference needed]. Figure 8 and Figure 9 In some embodiments, the sensor transfer device 10 further includes a first limiting part 18 and a second limiting part 721. The first limiting part 18 is disposed on the connector 1 and moves along the second direction Z with the connector 1. The second limiting part 721 is disposed on the inner wall of the receiving member 7. The first limiting part 18 and the second limiting part 721 cooperate to limit the maximum displacement of the connector 1 towards the second side of the second direction Z. In this way, excessive movement of the connector 1 towards the second side of the second direction Z can be prevented, improving the operational safety of the sensor transfer device 10.

[0117] Specifically, see Figure 8 and Figure 9In some embodiments, the second limiting part 721 includes a groove 722, and the first limiting part 18 includes a ball 19. The ball 19 can engage or disengage from the groove 722 as the connector 1 moves along the second direction Z. Thus, when the connector 1 moves into position towards the second side of the second direction Z, the ball 19 reaches the groove 722 and engages, preventing the connector 1 from continuing to move relative to the final stage cylinder 72 towards the second side of the second direction Z. This effectively limits the maximum displacement of the connector 1 towards the second side of the second direction Z, improving operational safety. When the connector 1 leaves the position of maximum displacement towards the second side of the second direction Z, the ball 19 is compressed and disengages from the groove 722, thereby releasing the displacement restriction and allowing the connector 1 to smoothly move towards the first side of the second direction Z. Therefore, the cooperation of the ball 19 and the groove 722 effectively limits the maximum displacement of the connector 1 towards the second side of the second direction Z, improving operational safety, without affecting the movement of the connector 1 between other positions within its stroke range, achieving a safer and smoother operation.

[0118] In the foregoing embodiments, the driving mechanism 2 may include only one of the first driving mechanism 3 and the second driving mechanism 4, or it may include both the first driving mechanism 3 and the second driving mechanism 4. When the driving mechanism 2 includes both the first driving mechanism 3 and the second driving mechanism 4, it is more convenient for the connector 1 to move closer to or further away from the sensor 30 and to move the sensor. For example, the first driving mechanism 3 can drive the connector 1 to move along the first direction X, bringing the connector 1 to a position near the sensor 30. Then, the second driving mechanism 4 can drive the connector 1 to move along the second direction Y, bringing the connector 1 further closer to the sensor 30, so that the connector 1 can smoothly engage with the sensor 30 and switch detection points.

[0119] When the drive mechanism 2 includes both a first drive mechanism 3 and a second drive mechanism 4, the first drive mechanism 3 can be driven to connect with the connector 1 via the second drive mechanism 4. This results in a simpler and more compact structure. Furthermore, the second drive mechanism 4, together with the connector 1, can move along the first direction X under the drive of the first drive mechanism 3, facilitating the sequential movement along both the first direction X and the second direction Y, thus achieving a more efficient and orderly detection point switching process.

[0120] In addition, when the drive mechanism 2 includes both the first drive mechanism 3 and the second drive mechanism 4, the first drive mechanism 3 and the second drive mechanism 4 can be driven by different power mechanisms 9, or they can share the same power mechanism 9 and be driven by the same power mechanism 9.

[0121] For example, see Figures 1-4In some embodiments, the drive mechanism 2 includes a power mechanism 9, which is switched to engage with a first drive mechanism 3 and a second drive mechanism 4 to switch between driving the first drive mechanism 3 and the second drive mechanism 4. In this case, the first drive mechanism 3 and the second drive mechanism 4 share the same power mechanism 9 and are driven by the same power mechanism 9. Since the number of power mechanisms 9 is small, the structure is simpler, more compact, and lower in cost.

[0122] Specifically, see Figures 1-3 In some embodiments, the power mechanism 9 includes a power source 91 (e.g., a motor 93) and a switching mechanism 92. The switching mechanism 92 is driven by the power source 91 and alternately engages with the first drive mechanism 3 and the second drive mechanism 4, so that the power mechanism 9 alternately engages with the first drive mechanism 3 and the second drive mechanism 4. Thus, by simply controlling the switching mechanism 92 to alternately engage with the first drive mechanism 3 and the second drive mechanism 4, the power mechanism 9 can be controlled to alternately engage with the first drive mechanism 3 and the second drive mechanism 4, allowing the first drive mechanism 3 and the second drive mechanism 4 to be driven by the same power mechanism 9, simplifying the structure and reducing costs.

[0123] The switching mechanism 92 can take various structural forms. As one example, see... Figures 1-3 In some embodiments, the switching mechanism 92 includes a clutch 96 (e.g., a dual electromagnetic clutch 97). This allows for convenient control of the power source 91 to switch between driving the first drive mechanism 3 and the second drive mechanism 4.

[0124] For example, see Figures 1-3 In some embodiments, where the first drive mechanism 3 includes the aforementioned first gear 34 and the second drive mechanism 4 includes the aforementioned third gear 89, the first gear 34 of the first drive mechanism 3 and the third gear 89 of the second drive mechanism 4 are rotatably mounted on the output shaft 95 of the power source 91. The clutch 96 of the switching mechanism 92 is mounted on the output shaft 95 and rotates with the output shaft 95. The clutch 96 is located between the first gear 34 and the third gear 89 and engages with the first gear 34 and the third gear 89 in a switching manner.

[0125] Since the clutch 96, the first gear 34 of the first drive mechanism 3, and the third gear 89 of the second drive mechanism 4 are all mounted on the output shaft 95, and the clutch 96 is located between the first gear 34 and the second gear 88, the clutch 96 can be easily switched between engaging with the first gear 34 and the second gear 88. For example, when the clutch 96 is a dual electromagnetic clutch 97, it is only necessary to control the energization of the end of the dual electromagnetic clutch 97 facing the first gear 34 and the end facing the second gear 88 to switch between engaging with the first gear 34 and the second gear 88, which is simple and convenient.

[0126] Furthermore, since both the first gear 34 of the first drive mechanism 3 and the second gear 88 of the second drive mechanism 4 can rotate relative to the output shaft 95, and the clutch 96 rotates along with the output shaft 95, when the clutch 96 is not engaged with the first gear 34 and the second gear 88, the power source 91 will only drive the clutch 96 to rotate, not the first gear 34 and the second gear 88, and will not drive the first drive mechanism 3 or the second drive mechanism 4 to operate. Only when the clutch 96 is engaged with the first gear 34 or the second gear 88 can the power source 91 drive the first gear 34 or the second gear 88 to rotate, thereby driving the first drive mechanism 3 or the second drive mechanism 4 to operate, controlling the connector 1 to move closer to or further from the sensor 30 and driving the sensor 30 to move, thus achieving the switching of the detection point. This is more conducive to controlling the orderly movement in both directions and achieving a safer and more reliable detection point switching process.

[0127] In the foregoing embodiments, the connector 11 can be engaged with the sensor 30 using various methods such as clamping and adsorption. For example, see... Figure 9 In some embodiments, the connector 11 includes a magnetic member 12, which is used to magnetically attract the sensor 30 to engage with it. In this case, the connector 11 engages with the sensor 30 using a magnetic attraction method, which is simple and convenient, and is less likely to damage the sensor 30, making it safer and more reliable.

[0128] For easier connection of connector 11 and sensor 30, see [link / reference] Figure 9 In some embodiments, the connector 1 includes not only a connector 11, but also a rotating member 13. The connector 11 is disposed on the rotating member 13, and the rotating member 13 is rotatably disposed to drive the connector 11 to rotate.

[0129] Based on the above configuration, the connector 11 can not only move closer to or further away from the sensor 30 under the action of the drive mechanism 2 and drive the engaged sensor 30 to move between different positions, but also rotate under the drive of the rotating member 13 to change its angle and position, facilitating the engagement of the connector 11 with the sensor 30 or the retraction of the connector 11. For example, when it is necessary to engage with the sensor 30, the connector 11 can rotate with the rotating member 13 to the angle where the sensor 30 is located after being driven into place by the drive mechanism 2, thus facilitating the engagement of the connector 11 with the sensor 30. For another example, when the sensor transfer device 10 has transported the sensor 30 to its position and the sensor transfer device 10 does not need to change the position of other sensors 30, the connector 11, which is separated from the sensor 30, can be rotated to an angle that will not interfere with other components during the retraction process under the action of the rotating member 13, facilitating the retraction of the connector 11 into place. In this way, the operation of the sensor transfer device 10 can be smoother, more efficient, and safer and more reliable.

[0130] Additionally, see Figure 9 In some embodiments, the connector 1 includes not only the connector 11, but also a vibration damping member 15. The vibration damping member 15 dampens the vibration of the connector 11 during its movement. This improves the smoothness of the movement of the connector 11, making it easier for the connector 11 to engage and disengage from the sensor 30 more smoothly and efficiently, as well as for transporting the sensor 30. Furthermore, it reduces vibration noise, enabling a quieter detection point switching process.

[0131] Specifically, see Figure 9 In some embodiments, the damping element 15 is conical. In this way, the damping element 15 can achieve damping in more directions, resulting in better damping effect, which is more conducive to improving the smoothness of the operation of the sensor transfer device 10 and reducing the operating noise of the sensor transfer device 10.

[0132] The sensor transfer device 10 in the aforementioned embodiments can drive the sensor 30 to move between stationary parts of the mechanical equipment, increasing the detection data without increasing the number of sensors 30, making the fault monitoring signal more comprehensive and accurate, and facilitating accurate diagnosis of fault type and fault source.

[0133] The sensor transfer device 10 can engage with the sensor 30 in various situations and drive the sensor 30 to move between different positions.

[0134] As one method, when there is a fault alarm signal and it is necessary to determine the source of the fault, for example, when there is a fault in the engine and a fault alarm signal is issued, and it is necessary to determine which part of the engine is the source of the fault, the sensor transfer device 10 is engaged with the sensor 30 outside the area corresponding to the fault alarm signal, and the engaged sensor 30 is moved to the area corresponding to the fault alarm signal to perform detection, so as to provide more signals and facilitate accurate location of the fault source.

[0135] For example, in the absence of a fault alarm signal, the sensor transfer device 10 can be connected to the sensor 30, and the connected sensor 30 can be moved between different parts of the mechanical equipment to perform inspections, thereby realizing the function of regular inspections, so as to achieve early detection and early handling, further improve the comprehensiveness, accuracy and timeliness of fault monitoring, and more effectively reduce the economic losses and safety accidents caused by faults.

[0136] Therefore, see Figure 13 This application also provides a fault monitoring method, which includes:

[0137] In response to a fault alarm signal, the sensor transfer device 10 engages with a sensor 30 located outside the area corresponding to the fault alarm signal, and moves the engaged sensor 30 to the area corresponding to the fault alarm signal for detection; and / or,

[0138] In response to the inspection command, the sensor transfer device 10 engages with the sensor 30, and drives the engaged sensor 30 to move between different parts of the mechanical equipment to perform the inspection.

[0139] The fault monitoring method of this application can be performed under the control of the controller 40. Therefore, this application also provides a controller 40, which includes a memory and a processor coupled to the memory, the processor being configured to execute the fault monitoring method of any embodiment based on instructions stored in the memory.

[0140] Additionally, see Figure 12 This application also provides a fault monitoring system 100, which includes a sensor 30 and a sensor transfer device 10 according to any embodiment of this application. Furthermore, in some embodiments, the fault monitoring system 100 also includes a controller 40 according to any embodiment of this application.

[0141] Furthermore, this application also provides a mechanical system, which includes mechanical equipment and a fault monitoring system 100 according to any embodiment. The fault monitoring system 100 is used to monitor and diagnose faults in mechanical equipment (such as engineering vehicles and other construction machinery) in order to detect and eliminate faults in a timely manner, thereby reducing economic losses and safety hazards.

[0142] The following will provide further details. Figures 1-13 The example shown.

[0143] First, let's introduce Figures 1-11 An embodiment of the sensor transfer device 10 shown.

[0144] In this embodiment, the sensor transfer device 10 is mounted on the engineering vehicle and arranged vertically, with the first direction X and the second direction Z along the horizontal and vertical directions, respectively.

[0145] The engineering vehicle is equipped with multiple sensors 30 of different types and models. The sensor transfer device 10 is used to change the position of the sensors 30 when needed, realizing rapid switching of detection points, making the monitoring signals comprehensive and accurate, and improving the accuracy of fault diagnosis. When there is no need for position change, the sensor transfer device 10 can also be retracted into a small space to reduce interference with the entire vehicle.

[0146] Specifically, such as Figures 1-11As shown, in this embodiment, the sensor transfer device 10 includes a connector 1 and a drive mechanism 2. The connector 1 is used for detachable engagement with the sensor 30 and includes a magnetic suction member 12, a rotating member 13, a mounting base 14, a vibration damping member 15, a guide rod 16, and a support 17 serving as a connecting member 11. The drive mechanism 2 is used to drive the connector 1 to move along the first direction X (i.e., horizontal movement) and along the second direction Z (i.e., lifting). It includes a first drive mechanism 3, a second drive mechanism 4, and a power mechanism 9. The first drive mechanism 3 includes a rack 33 serving as a guide 31 and a first gear 34 serving as a moving member 32. The second drive mechanism 4 includes a first drive member 5, a second drive member 6, a housing member 7 including a three-stage sleeve 71 (i.e., a rotating cylinder 74, a linkage cylinder 73, and a final stage cylinder 72), an elastic member 77, a column 78, and a base 79, two linkage mechanisms 81 including rollers 82 and pulling members 83, two actuation mechanisms 84 including rotating wheels 85 and traction members 86, and a transmission mechanism 87 including a second gear 88 and a third gear 89. The power mechanism 9 includes a motor 93 serving as a power source 91 and a dual electromagnetic clutch 97 serving as a switching mechanism 92.

[0147] Among them, the power mechanism 9 is used to provide the power required for horizontal movement and lifting. Figure 3 The combined structure of the power mechanism 9 with the first gear 34 of the first drive mechanism 3 and the third gear 89 of the second drive mechanism 4 is shown. Figure 3 As shown, in this embodiment, the motor 93 is arranged vertically, and its output shaft 95 extends vertically (i.e., the axial direction of the output shaft 95 is along the second direction Z). A support platform 98 is provided on one side of the upper end of the motor 93. The first gear 34, the dual electromagnetic clutch 97, and the third gear 89 are sequentially sleeved on the output shaft 95 from bottom to top, such that the dual electromagnetic clutch 97 is located between the first gear 34 and the third gear 89, with its upper and lower ends facing the third gear 89 and the first gear 34, respectively. Thus, when the upper and lower ends of the dual electromagnetic clutch 97 are energized, they can engage with the third gear 89 and the first gear 34, respectively. The dual electromagnetic clutch 97 rotates together with the output shaft 95, and bearings are provided between the first gear 34 and the third gear 89 and the output shaft 95, so that the first gear 34 and the third gear 89 can rotate relative to the output shaft 95.

[0148] Based on the above settings, when the motor 93 starts, it can drive the dual electromagnetic clutch 97 to rotate. The lower end of the dual electromagnetic clutch 97 is energized first, so that the dual electromagnetic clutch 97 engages with the first gear 34, realizing the drive connection between the motor 93 and the first gear 34. This allows the first gear 34 to rotate under the drive of the motor 93, and during the rotation, it moves along the rack 33 extending in the first direction X, realizing the horizontal movement of the other structures of the sensor transfer device 10 except for the rack 33, so as to drive the connector 1 to move horizontally to the specified horizontal position. Afterward, the lower end of the dual electromagnetic clutch 97 is de-energized and the upper end is energized, so that the dual electromagnetic clutch 97 switches to engage with the third gear 89, realizing the drive connection between the motor 93 and the third gear 89. This allows the third gear 89 to rotate under the drive of the motor 93, and then drives the rotating cylinder 74 to rotate by meshing with the second gear 88.

[0149] The rotating cylinder 74, the linkage cylinder 73, and the final stage cylinder 72 are arranged sequentially from bottom to top and nested sequentially from the outside to the inside to accommodate the connector 1 and provide three-stage power.

[0150] The rotating cylinder 74 is rotatably mounted and rotates under the drive of the second gear 88 of the transmission mechanism 87 to provide the first stage of power to drive the linkage cylinder 73 to rise and fall.

[0151] Figure 4 The combined structure of the rotating cylinder 74 with the second gear 88, the elastic element 77, the column 78 and the base 79 is shown.

[0152] like Figure 4 As shown, in this embodiment, the base 79 is detachably connected to the support platform 98 of the power mechanism 9 by bolts or the like (see...). Figure 2 The elastic element 77, constructed as a spring 61, is located within the rotating cylinder 74. Its lower end is fixed and immovable in the vertical direction (second direction Z), while its upper end is connected to the final stage cylinder 72. This provides a downward elastic force to the final stage cylinder 72, allowing it to descend when it reaches a designated position. This improves the reliability of the final stage cylinder 72's reset. A column 78 is located within the rotating cylinder 74 and surrounded by the elastic element 77. The upper and lower ends of the column 78 are connected to the final stage cylinder 72 and the base 79, respectively. Thus, the column 78 not only guides the extension and retraction of the elastic element 77 but also provides support for the final stage cylinder 72 in the vertical direction, especially when it reaches its highest position.

[0153] The rotating cylinder 74 is sleeved outside the elastic member 77 and fixedly connected above the second gear 88. It rotates together with the second gear 88, so that when the second gear 88 rotates under the drive of the third gear 89, it can drive the rotating cylinder 74 to rotate, so that the rotating cylinder 74 drives the linkage cylinder 73 to rise and fall by rotating.

[0154] The linkage cylinder 73 is vertically and elliptically arranged inside the rotating cylinder 74. It is used to convert the rotation of the rotating cylinder 74 into the lifting and lowering of the final stage cylinder 72 through two actuation mechanisms 84, so as to provide the second stage power to drive the final stage cylinder 72 to lift and lower.

[0155] Figure 5 The diagram illustrates the coordination relationship between the linkage cylinder 73, the rotating cylinder 74, and the two actuation mechanisms 84.

[0156] like Figure 5 As shown, in this embodiment, the outer wall of the linkage cylinder 73 is provided with threads, and correspondingly, the inner wall of the rotating cylinder 74 is provided with threads, so that the linkage cylinder 73 and the rotating cylinder 74 are threadedly connected. In this way, when the rotating cylinder 74 rotates, it can drive the linkage cylinder 73 to rise and fall.

[0157] Furthermore, combined Figure 5 and Figure 3 As can be seen, in this embodiment, two actuation mechanisms 84 are disposed between the linkage cylinder 73 and the final stage cylinder 72, and located on opposite sides of the final stage cylinder 72. The two actuation mechanisms 84 have the same structure, each including a rotating wheel 85 and a traction member 86. The rotating wheel 85 is a sprocket, rotatably disposed on the upper end of the inner wall of the linkage cylinder 73, and rises and falls together with the linkage cylinder 73. The traction member 86 is a chain, with its first end (i.e., the lower end) fixed and immovable in the vertical direction, and its second end (i.e., the upper end) bypassing the rotating wheel 85 and connected to the lower end of the final stage cylinder 72 (i.e., the end of the final stage cylinder 72 furthest from the first driving member 5). Specifically, it is connected to two protrusions 75 on the lower part of the outer wall of the final stage cylinder 72 (see...). Figure 6 )superior.

[0158] Based on the above configuration, when the linkage cylinder 73 rises, it drives the two rotating wheels 85 to rise, causing one side (the side away from the final stage cylinder 72) of the two traction members 86 to lengthen and the other side (the side closer to the final stage cylinder 72) to shorten. As a result, the second ends of the two traction members 86 rise, pulling the final stage cylinder 72 upward, causing the final stage cylinder 72 to rise. When the linkage cylinder 73 descends, it drives the two rotating wheels 85 to descend. At this time, one side (the side away from the final stage cylinder 72) of the two traction members 86 shortens and the other side (the side closer to the final stage cylinder 72) lengthens, causing the two traction members 86 to loosen. The second ends of the two traction members 86 no longer pull the final stage cylinder 72 upward. Thus, the final stage cylinder 72 can descend smoothly under the action of gravity and the pulling force of the elastic member 77.

[0159] The final stage cylinder 72 is vertically and vertically disposed inside the linkage cylinder 73. It is used to convert the lifting and lowering of the linkage cylinder 73 into the opening and closing of the first driving member 5 through two linkage mechanisms 81, so as to provide the third stage power to drive the first driving member 5 to open and close.

[0160] Figure 6 The diagram shows the relationship between the final stage cylinder 72, the two linkage mechanisms 81, and the first drive component 5.

[0161] like Figure 6 As shown, in this embodiment, the lower end of the outer wall of the final stage cylinder 72 is provided with two protrusions 75. These two protrusions 75 are symmetrically arranged, and, combined with Figure 6 , Figure 2 and Figure 5 It can be seen that the two protrusions 75 are respectively connected to the second end of the traction member 86 of the two actuation mechanisms 84, realizing the driving connection between the final stage cylinder 72 and the two actuation mechanisms 84, so that the final stage cylinder 72 can rise and fall with the linkage cylinder 73 under the action of the two actuation mechanisms 84.

[0162] A sensor 76 is provided at the top of the final stage cylinder 72 to detect obstacles during the lifting and lowering process of the final stage cylinder 72, especially during the lifting process, in order to prevent the final stage cylinder 72 from colliding with obstacles. Specifically, as shown... Figure 6 As shown, in this embodiment, two sensors 76 are provided at the top of the final stage cylinder 72. These two sensors 76 are arranged opposite each other to detect obstacles from both sides, thereby more reliably preventing collisions. Once an obstacle is detected and a collision risk is found, a signal is issued to promptly alarm and request a change of position.

[0163] The upper end of the final stage cylinder 72 is open, forming an end opening 723 (see...). Figure 2 The first drive element 5 is closably disposed on the end opening 723 to open and close the end opening 723, facilitating the control of the connector 1 extending or retracting.

[0164] Two linkage mechanisms 81 are disposed between the final stage cylinder 72 and the linkage cylinder 73, and located on opposite sides of the final stage cylinder 72. The two linkage mechanisms 81 have identical structures, each including a roller 82 and a pulling member 83. The roller 82 is a pulley, rotatably mounted on the upper end of the outer wall of the final stage cylinder 72, and rises and falls together with the final stage cylinder 72. The pulling member 83 is a rope, with its first end (lower end) fixed and immovable in the vertical direction, and its second end (upper end) passing around the roller 82 and connected to the two covers 51 of the first drive member 5, providing power for the opening and closing of the first drive member 5.

[0165] The first driving member 5 includes two covers 51, both of which are located at the end opening 723 and are arranged opposite each other in the first direction X. Furthermore, the two covers 51 have identical structures, each including three cover plates 52. These three cover plates 52 are arranged sequentially along the first direction X. The cover plate 52 furthest from the other cover 51 is fixed and does not move along the first direction X, while the other two cover plates 52 can move along the first direction X. Thus, the first direction X forms the opening and closing direction. The three cover plates 52 of the same cover 51 are connected sequentially along the opening and closing direction and can move relative to each other in the opening and closing direction, allowing the two covers 51 to move closer or further apart, thereby realizing the opening and closing of the first driving member 5.

[0166] Specifically, a bracket 55 is provided at the end opening 723, and a sliding groove 56 is provided on the bracket 55. Two of the three cover plates 52 are movable along the sliding groove 56. More specifically, one of the two movable cover plates 52 is provided with a limiting member 54 (e.g., a limiting pin). The limiting member 54 is slidably connected to the sliding groove 56, which plays a sliding guiding role, guiding the cover plate 52 to move along the sliding groove 56, and can limit the displacement of the cover plate 52 in the vertical direction, which is conducive to achieving a smoother and more stable opening and closing process.

[0167] Both covers 51 are connected to the pulling member 83 of the linkage mechanism 81 through the cover plate 52 closest to the other cover 51, so as to realize the driving connection between the pulling member 83 and the cover 51.

[0168] Figure 7 The fit between the three cover plates 52 of the cover body 51 is further illustrated. For example... Figure 7 As shown, in this embodiment, a reset member 53 is provided between any two adjacent cover plates 52. The reset member 53 is constructed as a spring 61 and applies an elastic force to the two cover plates 52 to move them away from each other. In this way, after the pulling member 83 is released, each cover plate 52 of the cover body 51 can automatically reset under the push of the reset member 53, thereby closing the first driving member 5.

[0169] Based on the above configuration, when the final stage cylinder 72 rises, it can drive the two pulling members 83 to apply a reverse pulling force to the two covers 51 in the opening and closing direction, while compressing the reset members 53 in the two covers 51, pulling the two covers 51 open to the edge, thereby opening the first driving member 5; when the final stage cylinder 72 descends, the two pulling members 83 are released, and the compressed reset members 53 then push the covers 51 to reset, thereby closing the first driving member 5.

[0170] It can be seen that the housing 7, the linkage mechanism 81, the actuation mechanism 84, and the transmission mechanism 87 can work together to drive the first driving component 5 to open and close.

[0171] When the first driving member 5 is opened, the end opening 723 opens, allowing the connector 1 to pass and allowing the connector 1 to rise under the action of the second driving member 6, extending outside the final stage cylinder 72 and engaging with the sensor 30. When the first driving member 5 is closed, it can squeeze the connector 1, causing the connector 1 to descend and retract into the final stage cylinder 72.

[0172] Figure 9 The structure of connector 1 and second drive unit 6 is shown.

[0173] like Figure 9 As shown, in this embodiment, connector 1 includes a support 17, a guide rod 16, a damping element 15, a mounting base 14, a rotating element 13, and a magnetic attractor 12 serving as a connecting element 11. The second driving element 6 is configured as a spring 61. The guide rod 16 is connected to the support 17. The damping element 15 is disposed at the top of the guide rod 16 and is a conical damping rubber made of vulcanized rubber with a metal shell, capable of damping vibrations in the up-down, left-right, and front-back directions. The mounting base 14 is disposed above the damping element 15. The rotating element 13 is configured as a ball joint and is rotatably disposed on the mounting base 14. The magnetic attractor 12 is disposed on the rotating element 13 and rotates together with the rotating element 13. The second driving element 6 surrounds the outside of the guide rod 16. Furthermore, combined with… Figure 2 It is understood that the support 17 is vertically and flexibly disposed within the final stage cylinder 72, and the second drive member 6 abuts against the damping member 15 and the final stage cylinder 72, applying an upward elastic force to the damping member 15. Thus, when the first drive member 5 is not open, the connector 1 is entirely located within the final stage cylinder 72 and can rise together with the final stage cylinder 72; however, when the first drive member 5 is open, as... Figure 10 and Figure 11 As shown, the connector 1 as a whole can rise relative to the final stage cylinder 72 under the action of the second driving member 6, so that the magnetic suction member 12 extends to the outside of the final stage cylinder 72.

[0174] Depend on Figure 9 As can be seen, in this embodiment, the side wall of the support 17 is also provided with a ball bearing 19 serving as a first limiting part 18. The ball bearing 19 is a spring ball bearing, which can both rise and fall with the connector 1 and move radially relative to the support 17 in the final stage cylinder 72. Correspondingly, the inner wall of the final stage cylinder 72 is provided with a groove 722 serving as a second limiting part 721. When the connector 1 rises to the highest position relative to the final stage cylinder 72, the ball bearing 19 is engaged in the groove 722, preventing the connector 1 from rising further, thereby limiting the maximum upward displacement of the support device 1.

[0175] After the magnetic chuck 12 extends outside the final stage cylinder 72, the rotating component 13 can be rotated to a suitable angle so that the magnetic chuck 12 faces the sensor 30. Simultaneously, the magnetic chuck 12 is energized, generating a strong magnetic field that attracts the sensor 30. Then, under the action of the first drive mechanism 3, the sensor transfer device 10 moves the sensor 30 to the target position. Afterward, the magnetic chuck 12 is de-energized, separating from the sensor 30, allowing the sensor 30 to fall to the target position for detection. If the sensor transfer device 10 has completed its work and there is no need to transfer the sensor 30 further, the motor 93 can reverse its operation, controlling the first drive component 5 to close, pressing the connector 1 downwards, and compressing the second drive component 6, so that the entire connector 1 is pressed into the final stage cylinder 72. After the first drive component 5 is fully closed, it provides dustproof, rainproof, and impact-proof protection for the connector 1.

[0176] As can be seen, the sensor transfer device 10 of this embodiment can quickly switch the position of the sensor 30, effectively solving the problem of missed diagnosis and misdiagnosis due to insufficient number of sensors. It can provide more acquisition signals without increasing the number of sensors 30, realize a more comprehensive, efficient and accurate fault monitoring process, and improve the diagnostic accuracy of fault type and fault source.

[0177] Moreover, the sensor transfer device 10 of this embodiment can retract into a small space when not in operation, occupying less space and having less impact on the overall vehicle layout.

[0178] Meanwhile, the second drive mechanism 4 for lifting the drive connector 1 of the sensor transfer device 10 does not adopt a structure different from other structures such as drive cylinders (e.g., hydraulic cylinders). It is not only accurate in positioning and inexpensive, but also has a high lifting distance after extension and a small overall height after retraction. This facilitates the connection between the sensor transfer device 10 and the sensor 30, and also helps to reduce the space occupied by the sensor transfer device 10 when it is not working, thus reducing the impact on the overall vehicle layout.

[0179] Next, we will introduce... Figure 12 and Figure 13 Examples of fault monitoring systems and methods are shown.

[0180] like Figure 12 As shown, in this embodiment, the fault monitoring system 100 includes a data acquisition module 20, which includes a sensor 30. The sensor 30 is used to detect parameters of the mechanical equipment (such as temperature, vibration, or pressure) to acquire signals of the real-time status of the mechanical equipment and obtain data for fault monitoring and diagnosis.

[0181] Specifically, such as Figure 12As shown, in this embodiment, the data acquisition module 20 includes multiple sensors 30. Similarly, the fault monitoring system 100 includes multiple sensors 30. These multiple sensors 30 can be arranged in different parts of the mechanical equipment to detect different parts, and the parameters detected can be the same or different. For example, in some embodiments, these multiple sensors 30 include various sensors such as temperature sensors, vibration sensors, pressure sensors, and speed sensors, and each type of sensor can be one or more, and their models can be the same or different. This allows for the detection of more parts and more parameters, facilitating a more comprehensive and accurate fault monitoring and diagnosis process.

[0182] Moreover, such as Figure 13 As shown, in this embodiment, the fault monitoring system 100 includes not only the data acquisition module 20, but also the controller 40, the diagnostic module 50, the display module 60, and the storage module 70.

[0183] The diagnostic module 50 is signal-connected to the data acquisition module 20 to perform fault diagnosis based on the detection results of the data acquisition module 20, determining the fault type and fault source. Specifically, in some embodiments, the data detected by each sensor 30 of the data acquisition module 20 is transmitted to the diagnostic module 50. The diagnostic module 50 initiates an objective parameter extraction process, inputs the extracted objective parameter values ​​into a large database model, and uses the big data model to diagnose the fault type and fault source, thereby achieving fault diagnosis.

[0184] The display module 60 is used for information display. On one hand, the sensors 30 of the data acquisition module 20 provide daily monitoring for the mechanical equipment. Once the monitoring results exceed the threshold, an alarm program will be activated and the alarm results will be displayed on the screen of the display module 60 in a timely manner. On the other hand, the display module 60 is signal-connected to the diagnostic module 50 to display fault diagnosis results, so as to prompt timely repair or replacement of parts. For example, in some embodiments, when the diagnostic module 50 diagnoses a fault, the display module 60 will issue an alarm, display the fault type and fault source, and propose repair or replacement suggestions.

[0185] The storage module 70 is signal-connected to the diagnostic module 50. It is used to extract fault data and diagnostic results obtained by the diagnostic module 50, continuously enrich the big data model, and store the verified and accurate diagnostic results in the storage module 70. These results are then uploaded to a general-purpose big data database via cloud storage, allowing them to be transferred as prior knowledge to other similar or identical mechanical equipment. During actual operation, after the display module 60 displays a fault alarm signal, it connects to the storage module 70. By comparing the display module 60 with the fault alarm signal, the initial fault mode is determined and fed back to the controller 40.

[0186] The controller 40 is connected to other modules such as the diagnostic module 50 to receive signals from other modules and control their operation.

[0187] Furthermore, by Figure 12 As can be seen, in this embodiment, the fault monitoring system 100 also includes a sensor transfer device 10. The sensor transfer device 10 is signal-connected to the controller 40 to operate under the control of the controller 40. The controller 40 can control the sensor transfer device 10 to move closer to or further away from the sensor 30 by issuing a position change command to the sensor transfer device 10, thereby causing the sensor 30 to move.

[0188] Fault monitoring system 100 can be configured according to Figure 13 The fault monitoring method shown is in operation.

[0189] like Figure 13 As shown, during operation, after receiving a fault alarm signal (also known as a fault warning signal) and a preliminary fault mode, the controller 40 determines the travel path of the sensor transfer device 10 and sends a position change command to the sensor transfer device 10. The controller then controls the sensor transfer device 10 to travel along the determined path, engage with the required sensor 30, and move the corresponding sensor 30 to the area corresponding to the fault alarm signal (i.e., the area where the fault source may exist) for detection. This provides more detection data for the diagnostic module 50 to more accurately diagnose the fault mode and fault source. For example, when an alarm signal is issued at a certain part of the engine, the sensor transfer device 10 can move sensors 30 from other components such as the reducer or other parts of the engine to the corresponding alarm location on the engine to collect more signals, thus more accurately determining the engine fault source.

[0190] In addition, even when no fault alarm signal appears, the controller 40 can also send a position change command to the sensor transfer device 10 to form an inspection command. The sensor transfer device 10 carries the sensor 30 to perform regular inspections of the entire mechanical equipment.

[0191] Because it can move the sensor 30 in a timely manner through the sensor transfer device 10 when a fault warning occurs, so as to collect as many signals as possible and locate the fault source, and can also perform systematic and comprehensive fault diagnosis on a regular basis, so as to achieve self-diagnosis and real-time diagnosis, it can reduce costs, save time, improve the accuracy and timeliness of fault diagnosis, and effectively reduce property losses and personal safety accidents.

[0192] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this application or equivalent substitutions can be made to some technical features, all of which should be covered within the scope of the technical solutions claimed in this application.
