Description

Technical Field

[0001] The present invention relates to the technical field of vibration amplitude detection, and particularly to a vibration amplitude detection device for a variable-frequency speed-regulating integrated machine. Background Art

[0002] A variable-frequency speed-regulating integrated machine is a mechanical device that combines a frequency converter and a motor. During actual use, due to the requirements of its working characteristics, the variable-frequency speed-regulating integrated machine usually vibrates to a certain extent. The amplitude of the vibration will affect the actual working effect of the device to a certain extent. Therefore, it is necessary to regularly detect the variable-frequency speed-regulating integrated machine to ensure the yield rate.

[0003] Patent Publication No. CN115014787A discloses a device for effectively detecting the vibration amplitude of an engine block, including a base. A tray for installing the engine is provided on the base. A support frame is provided on one side of the base. A cylinder mechanism is provided on the support frame. The extending arm of the cylinder mechanism can move towards the engine on the tray. A vibration sensor is provided on the extending arm of the cylinder mechanism. When detecting the vibration amplitude of the engine, this patent uses the cylinder mechanism to send the vibration sensor into contact with the engine, and then detects the vibration amplitude of the engine through the vibration sensor. However, during the process of detecting the vibration amplitude of the engine in this patent, since the vibration of the engine is not regular, the local vibration amplitudes of the engine are inconsistent. And the measuring probe of the vibration sensor in this patent only contacts one place of the engine, so it can only detect the local vibration amplitude of the engine, resulting in the inability to intuitively display the vibration intensity during the actual detection process, thus affecting the actual detection effect.

Detailed implementation manners

[0030] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1: A vibration amplitude detection device for a variable frequency speed regulation integrated machine, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, including an installation rod 2, the installation rod 2 is symmetrically installed on the machine body 1, the installation rod 2 can be disassembled, four moving rods 8 are symmetrically and slidably connected to the installation rod 2, fixing rods 3 are fixedly connected to the outer sides of the front and rear moving rods 8, pushing rods 4 are fixedly connected to the tops of the two fixing rods 3, the upper sides of the two pushing rods 4 are inclined planes, contact plates 5 for conducting amplitude are fixedly connected to the inner sides of the front and rear moving rods 8, a third spring 17 is sleeved on the inner side of each moving rod 8, and the two ends of the third spring 17 are respectively connected to the contact plate 5 and the installation rod 2. A fixing frame 7 is fixedly connected to the left sides of the two installation rods 2, connecting rods 6 for conducting amplitude are fixedly connected to the front and rear sides of the upper part of the fixing frame 7, a moving frame 9 is slidably connected between the two connecting rods 6, guide rods 10 are fixedly connected to the front and rear sides of the bottom of the moving frame 9, a shock guide block 12 for receiving vibration is slidably connected to the two guide rods 10, a first spring 11 is connected between the lower parts of the two guide rods 10 and the bottom of the shock guide block 12, two guide rods 18 are fixedly connected to the left side of the moving frame 9, a guide frame 14 is slidably connected to the two guide rods 18, a fixing frame 13 is slidably connected to the upper part of the guide frame 14, a detector 16 is installed inside the fixing frame 13, two second springs 15 are connected between the bottom left side of the fixing frame 13 and the lower part of the guide frame 14, and a fourth spring 19 is connected between the bottom of the guide frame 14 and the lower parts of the two guide rods 18.

[0032] To ensure the accuracy of the detection results, the vibration frequencies of a large range of the body 1 can be detected. The mounting rod 2 is installed on the body 1 so that the connecting rod 6 is located at the top of the body 1 and contacts the body 1. When it is necessary to detect the vibration amplitude of the body 1, the body 1 is started. During the operation of the body 1, the vibration generated will drive the contact plate 5 to shake, and then drive the fixed rod 3 to move through the moving rod 8. The third spring 17 undergoes adaptive deformation. The fixed rod 3 drives the push rod 4 to move in and out, so that the push rod 4 pushes the moving frame 9 to move up and down. Then, the moving frame 9 drives the shock guide block 12 to shake. And the connecting rod 6 contacts the body 1, and can conduct the overall vibration frequency of the body 1 to the shock guide block 12. The staff can manually press the detector 16 to move downward to contact the shock guide block 12. The detector 16 drives the fixed frame 13 to move downward, and the second spring 15 is compressed. During the vibration of the moving frame 9, the fourth spring 19 undergoes adaptive deformation to prevent the detector 16 from affecting the vibration of the shock guide block 12 and affecting the detection results. In this way, the vibration amplitude of the shock guide block 12 can be detected, and thus the vibration amplitude of the body 1 can be detected. If the vibration is too intense, it means that the body 1 needs to be repaired. After the detection is completed, the detector 16 is released, and the second spring 15 resets, driving the fixed frame 13 and the detector 16 to move upward and reset. The staff can also, according to needs, detect the local vibration of the body 1. Manually control the moving frame 9 to move to the position to be detected, and then press the detector 16, so that the detector 16 drives the shock guide block 12 to move downward, and the first spring 11 is compressed, so that the shock guide block 12 contacts the body 1. In this way, the specific local vibration can be detected, and more data can be obtained to improve the detection accuracy. After the end, the detector 16 is released, the first spring 11 resets, driving the shock guide block 12 to move upward and reset, and the detector 16 resets under the reset action of the second spring 15, and then the moving frame 9 is controlled to reset.

[0033] Embodiment 2: On the basis of Embodiment 1, please refer to Figure 6 and Figure 7 , and further includes a sliding rod 20. The sliding rod 20 is symmetrically and slidably connected to the fixed frame 7. The right sides of the two sliding rods 20 are both inclined planes. Two support rods 21 are fixedly connected to the upper left side of the fixed frame 7. The support rods 21 are L-shaped. Rotating blocks 22 for conducting the amplitude are rotatably connected to the lower parts of the two support rods 21. A torsion spring 23 is sleeved on the lower part of each support rod 21. The two ends of the torsion spring 23 are respectively connected to the lower part of the support rod 21 and the rotating block 22.

[0034] To ensure the accuracy of the detection results, the contact points for amplitude conduction can be increased. The rotating block 22 contacts the body 1. When the body 1 vibrates, it will strike the rotating block 22 to make it rotate. The torsion spring 23 undergoes adaptive deformation, causing the rotating block 22 to push the sliding rod 20 to move to the right. If the distance that the sliding rod 20 moves is greater than the distance that the contact plate 5 moves, it indicates that the amplitude on the left side of the body 1 is stronger than that in the middle of the body 1. And the side with larger vibration can push the push rod 4 to move a greater distance, thereby increasing the amplitude of the up-and-down jitter of the moving frame 9. In this way, the maximum value can be taken within different amplitudes, facilitating the detector 16 to detect the maximum vibration amplitude of the body 1, thus improving the accuracy of the detection results and facilitating the staff to judge whether the body 1 needs maintenance.

[0035] Please refer to Figure 8 and Figure 9 It also includes fixing plates 25. The two fixing plates 25 are respectively installed on the front and rear sides of the upper middle part of the body 1. The fixing plates 25 can be disassembled. Three sliding rods 24 are slidably connected to each of the two fixing plates 25. A fifth spring 27 is sleeved on the outside of each sliding rod 24. The two ends of the fifth spring 27 are respectively connected to the sliding rod 24 and the outside of the fixing plate 25. Contact blocks 26 for contacting the body 1 are fixedly connected to the rear sides of the three sliding rods 24 on the front side, and contact blocks 26 are fixedly connected to the front sides of the three sliding rods 24 on the rear side. The contact blocks 26 are arc-shaped.

[0036] To ensure the accuracy of the detection results, the contact blocks 26 are in close contact with the body 1. In this way, it can completely fit the surface of the body 1, avoiding the uneven surface of the body 1, which will affect the detection value. When the body 1 vibrates, the contact blocks 26 vibrate accordingly, and the fifth spring 27 undergoes adaptive deformation, so that a more intuitive amplitude can be conducted to the shock conduction block 12, improving the detection effect.

[0037] Please refer to Figure 10 、 Figure 11 and Figure 12 It also includes placing rods 28. Placing rods 28 are fixedly connected to the front and rear sides of the upper part of the fixing frame 7. The placing rods 28 are inclined. Limiting grooves 32 are evenly opened on the placing rods 28. Two rings 29 are placed on the two placing rods 28. Two clamping blocks 31 are fixedly connected to the inner walls of the two rings 29 through two telescopic components 30. The clamping blocks 31 contact the placing rods 28. The telescopic component 30 is composed of a telescopic rod and a spring. The telescopic rod is connected to the ring 29, and the spring is sleeved on the telescopic rod.

[0038] In order to be able to feel the vibration amplitude of the body 1 more intuitively, the position of the ring 29 can be observed. When the body 1 vibrates, the fixing frame 7 will vibrate accordingly, thereby driving the placement rod 28 to vibrate. The vibration of the placement rod 28 will drive the ring 29, the telescopic component 30 and the block 31 to vibrate. The telescopic component 30 performs adaptive deformation here. If the vibration is too severe, the ring 29 will move downward along the placement rod 28 during the vibration process. If the staff sees that the ring 29 descends too fast, they can immediately use the detector 16 to detect it, and then determine whether to perform maintenance, so that the staff can perform maintenance on the body 1 in time.
