Description

Technical Field

[0001] The present application relates to the technical field of vacuum pumps, and in particular to a vibration state monitoring device for a vacuum pump. Background Art

[0002] At present, the vacuum pump vibration status monitoring device is a system used to accurately evaluate the health status of the vacuum pump. It aims to continuously collect and analyze the vibration-related data generated by the vacuum pump during operation, so as to determine whether it is in normal working condition and to warn of possible failures in advance. The vibration sensor plays a key role in the vibration status monitoring of the vacuum pump. The vibration sensor can keenly capture the subtle vibration changes generated by the operation of the vacuum pump and convert these vibration information into electrical signals to transmit to the monitoring system; Through searching, a Chinese patent with a Chinese patent announcement number of "CN221171719U" discloses a monitoring device for vacuum pump vibration, which includes a horizontal plate, a control mechanism, two sliding bases, two vibration sensors, two fixed structures, two connecting structures, two shock absorbing mechanisms and two mounting structures; the two sliding bases are slidably connected to the horizontal plate, and each vibration sensor is detachably connected to a sliding base through a fixed structure. A travel slide is provided in the middle of the horizontal plate, and the two vibration sensors can slide in the travel slide. The detection of the vibration sensor touches the driving end housing of the bottom column vacuum pump. The two vibration sensors are connected to the control mechanism. The monitoring device for vacuum pump vibration described in the utility model solves the problem that the vibration of the vacuum pump cannot be detected in time and accurately due to the lack of a monitoring device for vacuum pump vibration in the related art, which leads to energy waste and instability of the equipment. With respect to the above-mentioned related technologies, the inventors found the following defects: Although the above device can assist in adjusting the left and right positions during use, during the detection process, it only relies on two sets of vibration sensors to assist in detection, and can only perform auxiliary detection on the top of the vacuum pump, and cannot flexibly adjust and detect various positions on both sides of the vacuum pump. When a single set of vibration sensors is used to detect one side of the vacuum pump, there are many disadvantages. Only detecting one side is likely to lead to an incomplete grasp of the overall vibration situation. It should be noted that the vibration of the vacuum pump often differs in different directions and positions. If the focus is only on one side, it is very easy to ignore the key vibration information of other parts, and then make an inaccurate judgment on its operating status. Secondly, unilateral detection may be useless. It cannot capture the complex vibration modes caused by the interaction or imbalance between components. For example, some faults may cause the vibration to propagate in multiple directions, but single-side detection is difficult to fully present such complex vibration characteristics. Furthermore, given the structure and working principle of the vacuum pump itself, the vibration may propagate and reflect internally. If only one side is detected, it is very likely to be disturbed by these propagations and reflections, which will ultimately lead to inaccurate test results. In addition, if the fault happens to occur on the undetected side, it is very likely that the problem will not be detected in time, thereby delaying the best time for maintenance and processing. It can be seen that there are certain defects and deficiencies in the overall monitoring period, so it needs to be improved. Summary of the invention

DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-8 This application is described in further detail.

[0018] The present application embodiment discloses a vacuum pump vibration state monitoring device. Figure 1-8 As shown, it comprises a frame 1, mounting mechanisms 2 are movably mounted on both sides of the interior of the frame 1, an adjustment mechanism 3 is fixedly mounted on the front side of the frame 1, the rear side of the adjustment mechanism 3 is connected to the front end of the mounting mechanism 2, a transverse rail frame 4 is fixedly mounted on the middle part of the inner side of the frame 1, and two sets of monitoring mechanisms 5 are slidably connected inside the transverse rail frame 4;

[0019] The monitoring mechanism 5 includes a slider 51, which is slidably connected to the inside of the transverse rail frame 4. The slider 51 is arranged in two groups. Connecting arms 52 are fixedly installed on both sides of the slider 51. Arc-shaped slide rails 53 are fixedly installed on the outer ends of the connecting arms 52. Monitoring components 56 are movably installed at equal intervals on the outer sides of the arc-shaped slide rails 53. The mounting mechanisms 2 on both sides of the frame 1 are movably installed, so that the device can flexibly adapt to vacuum pumps of different specifications and ensure stable installation. The adjustment mechanism 3 is connected to the mounting mechanism 2, and can accurately adjust the position and state of the mounting mechanism 2, thereby enhancing the adaptability of the device. In order to improve the convenience of operation, the transverse rail frame 4 in the middle of the inner side of the frame 1 and the two sets of monitoring mechanisms 5 slidably connected therein greatly improve the coverage and accuracy of monitoring. The slider 51 slides flexibly in the transverse rail frame 4, and cooperates with the connecting arms 52 on both sides and the arc-shaped slide rail 53 at the outer end to monitor the vacuum pump in an all-round manner. The monitoring components 56 arranged at equal intervals on the outer side of the arc-shaped slide rail 53 further refine the density and accuracy of monitoring, ensuring that any tiny vibration changes are not missed, thereby realizing all-round, high-precision, flexible and detailed monitoring of the vibration state of the vacuum pump.

[0020] Please refer to Figure 1-Figure 4The mounting mechanism 2 includes a longitudinal rail frame 21, which is fixedly mounted on the front and rear sides of the bottom of the frame 1. A screw rod 22 is rotatably connected to the interior of the longitudinal rail frame 21. The screw threads of the two ends of the screw rod 22 are screwed in opposite directions. Both ends of the screw rod 22 are threadedly connected to a clamping arm 23. A clamping frame 24 is fixedly mounted on the lower end of the clamping arm 23. The inner cross-section of the clamping frame 24 is V-shaped. Anti-slip stripes are evenly spaced on the inner side of the clamping frame 24.

The design of the opposite rotation directions of the threads at both ends of the screw rod 22 is ingenious, so that when it rotates, it can simultaneously drive the clamping arms 23 connected by threads at both ends to move toward or away from each other, thereby quickly and accurately adjusting the clamping spacing to adapt to vacuum pumps of different sizes. The inner side of the clamping frame 24 at the lower end of the clamping arm 23 is V-shaped, and anti-slip stripes are provided at equal intervals, which can clamp the vacuum pump more closely, increase friction, ensure stable clamping, and prevent sliding and deviation.

The worm 33 and the worm gear 32 are transmission connected. A button handle 35 is fixedly connected to the outer side of a side plate 31. The button handle 35 and a worm 33 are fixedly connected. A hand-tightening screw 36 is fixedly connected to the outer side of the button handle 35. The hand-tightening screw 36 passes through the button handle 35 and is fitted and connected to the side plate 31. The side plate 31 is fixed to the front outer side of the longitudinal rail frame 21, providing a stable installation position for the worm gear 32 and the rotating shaft 34. The worm gear 32 is rotatably connected to The middle part of the front side of the longitudinal rail frame 21 is connected to the worm 33 at both ends of the rotating shaft 34, realizing efficient transmission and conversion of force. By rotating the button handle 35 fixedly connected to the worm 33, the rotating shaft 34 can be driven to rotate, so that the worm 33 drives the worm wheel 32 to rotate, thereby accurately controlling the movement of related components. The setting of the hand-tightened screw 36 is even more ingenious. It runs through the button handle 35 and is closely connected with the side plate 31. After the adjustment is completed, tightening the hand-tightened screw 36 can fix the button handle 35 to prevent accidental rotation, thereby ensuring the stability and accuracy of the adjustment.

[0022] Please refer to Figure 1-Figure 7The monitoring component 56 includes an arc-shaped movable block 561, which is slidably connected to the inside of the arc-shaped slide rail 53. The middle part of the arc-shaped movable block 561 is threadedly connected with an adjusting screw 562. The end of the adjusting screw 562 passes through the arc-shaped movable block 561 and is rotatably connected with a vibration sensor 563. A limiting member 564 is fixedly installed on the outer side of the arc-shaped movable block 561. The limiting member 564 includes a limiting frame 5641 and a limiting hole 5642. The limiting frame 5641 is fixedly installed on both ends of the outer side of the arc-shaped movable block 561. The limiting frame 5641 is fixedly connected to a limiting spring 5643 inside the limiting frame 5641. The outer end of the limiting spring 5643 is fixedly installed with a sliding block 5644. The sliding block 564 4 is fixedly connected to the outer side of the arc-shaped slide rail 53 with a limit pin 5645, and the limit holes 5642 are evenly spaced on both sides of the arc-shaped slide rail 53. The outer ends of the limit pins 5645 are inserted into the inner side of the limit holes 5642. The limit member 564 also includes a connecting plate 5646, which is arranged at the outer ends of the limit frame 5641. The bottom ends of the connecting plate 5646 are respectively fixedly connected to the two sliding blocks 5644 on one side of the limit frame 5641. Both ends of the vibration sensor 563 are fixedly connected to the limit ring 55, and the inner side of the limit ring 55 is slidably connected with the support shaft 54. The outer end of the support shaft 54 ​​is fixedly connected to the arc-shaped movable block. The arc-shaped movable block 561 in the monitoring component 56 can be in the arc-shaped movable block 561. The slide rail 53 slides inside, which makes the position of the vibration sensor 563 flexibly adjustable to meet different monitoring needs. The threaded connection between the adjusting screw 562 and the arc-shaped movable block 561 can accurately control the degree of fit between the vibration sensor 563 and the vacuum pump housing to ensure accurate detection of vibration. The design of the limiter 564 is very ingenious. The limiter frame 5641 is fixed at both ends of the outer side of the arc-shaped movable block 561. The internal limit spring 5643, the sliding block 5644 and the limit pin 5645 cooperate with each other. The limit holes 5642 are arranged at equal intervals, so that when the position of the arc-shaped movable block 561 is adjusted, the limit pin 5645 can be inserted into the corresponding limit hole 5642, which is effective. The vibration sensor 563 is stably positioned to prevent unnecessary displacement of the arc-shaped movable block 561 during the monitoring process, thereby ensuring the accuracy and stability of the monitoring. The setting of the connecting plate 5646 facilitates the simultaneous operation of the sliding blocks 5644 on both sides, making the adjustment and fixing operations more convenient and efficient. The limit rings 55 fixedly connected at both ends of the vibration sensor 563 are slidably connected to the support shaft 54, further ensuring the stability of the vibration sensor 563 during the adjustment and working process, reducing shaking and deviation. It can be seen that the design of the monitoring component 56 in the present device has many advantages such as flexible adjustment, precise positioning, and stable monitoring, and can comprehensively and accurately monitor the vibration state of the vacuum pump, thereby improving the monitoring effect and the reliability of the device.

[0023] The implementation principle of a vacuum pump vibration status monitoring device in the embodiment of the present application is as follows: by carefully setting up the installation mechanism 2, the device can be used to drive the rotating shaft 34 to rotate by twisting the button handle 35. When the rotating shaft 34 rotates, the two groups of worms 33 can be synchronously caused to rotate. In view of the transmission connection relationship between the worm 33 and the worm wheel 32, when the worm 33 rotates, the worm wheel 32 can be driven to rotate, and the rotation of the worm wheel 32 can drive the screw rod 22 to rotate. At this time, since the threads at both ends of the screw rod 22 have opposite rotation directions, as the screw rod 22 rotates, the clamping arms 23 can be synchronously driven to slide relative to each other. By adjusting the sliding displacement of the clamping arms 23, the clamping frame 24 can be made to fit closely to the two sides of the vacuum pump. Since the inner side of the clamping frame 24 is in a V shape The shaped design and the inner wall of the clamping frame 24 can contact the outer surface of the vacuum pump, and the anti-slip stripes can ensure that the device is firmly clamped and installed on the outer surface of the vacuum pump. After the installation is completed, it is only necessary to twist the hand-tightened screw 36 on the button handle 35 to make it close to and fit the outer side of the side plate 31 to achieve the locking and fixing of the button handle 35. Once the button handle 35 is fixed, the screw rod 22 is also fixed. When disassembly is required, it is only necessary to twist the hand-tightened screw 36 in the opposite direction. At this time, the locking state of the button handle 35 is released, and then the button handle 35 is twisted in the opposite direction to drive the worm 33 to reverse, and then drive the screw rod 22 to make the clamping arm 23 move toward the outside. In this way, the device can be quickly disassembled and assembled during application, which is convenient for maintenance of the device, and further significantly improves the overall convenience of use of the device. By cleverly arranging the monitoring mechanism 5, during the use of the device, after the device is successfully installed on the outer surface of the vacuum pump, the slider 51 can be adjusted to slide on the inner side of the transverse rail frame 4 according to actual needs. At this time, the positions of the two arc-shaped slide rails 53 on the left and right sides of the outer side of the vacuum pump can be adjusted. When the position adjustment is completed, it is only necessary to twist the adjusting screw 562 to drive the vibration sensor 563 close to the outer shell of the vacuum pump. On the one hand, the detection end of the vibration sensor 563 is tightly fitted to the outer shell of the vacuum pump, so that the vibration generated by the vacuum pump during operation can be effectively monitored by the vibration sensor 563; on the other hand, the vibration sensor 563 is fitted to the outer surface of the vacuum pump, and the arc-shaped slide rail 53 can also be fixed, thereby firmly fixing the slider 51. The device is fixed inside the transverse track, so that the device has an excellent positioning function. In addition, since multiple monitoring components 56 can be set on each arc-shaped slide rail 53, the position of the monitoring component 56 on the arc-shaped slide rail 53 can be flexibly adjusted by adjusting the sliding of the arc-shaped movable block 561. The arc-shaped movable block 561 will adaptively change the direction of the vibration sensor 563 during the sliding process. Therefore, no matter how the monitoring component 56 is adjusted on the arc-shaped slide rail 53, it can be adaptively attached to the outer surface of the vacuum pump. It can be seen that the device as a whole can install multiple groups of monitoring components 56 according to monitoring needs, so that each position on both sides of the vacuum pump can be monitored, the overall adaptability is stronger, the monitoring is more comprehensive, and its monitoring performance is effectively improved; By arranging the monitoring components 56 and the limiting components 564 to cooperate with each other, the device can be used to adaptively install multiple groups of monitoring components 56 according to the specific conditions to be monitored. Specifically, when in use, the arc-shaped movable block 561 can be slidably embedded in the interior of the arc-shaped slide rail 53. Since the arc-shaped movable block 561 and the arc-shaped slide rail 53 are both concentric arcs, the arc-shaped movable block 561 can be stably slid and embedded in the interior of the arc-shaped slide rail 53. During this period, since the limiting holes 5642 are arranged at equal intervals, the arc-shaped slider 51 can be adjusted to the required installation position according to the installation position. The limiting spring 5643 can be reset to drive the end of the limiting pin shaft 5645 to be inserted into the inner side of the limiting hole 5642, thereby positioning the arc-shaped movable block 561, and when it needs to be adjusted or installed again, During installation, it is only necessary to push the connecting plate 5646 to synchronously drive the two sliding blocks 5644 to move outward, so that the limiting spring 5643 inside the limiting frame 5641 can be pushed and pulled to make it in an extended state. At this time, the sliding block 5644 drives the limiting pin 5645 to disengage from the inner side of the limiting hole 5642. After adjusting the position, the connecting plate 5646 is released, and the limiting spring 5643 is reset. The sliding block 5644 can be pulled to drive the limiting pin 5645 to be inserted into the corresponding limiting hole 5642. During disassembly, the connecting plate 5646 can be adjusted to cause the limiting pin 5645 to disengage. At this time, the arc-shaped movable block 561 can be pulled out from the inside of the arc-shaped slide rail 53. It can be seen that the device as a whole is convenient for quick disassembly, assembly, maintenance and overhaul, which can further improve the convenience and flexibility of use of the device.

[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
