Example

[0021] Reference Figure 1-Figure 5 , an electromechanical monitoring device, comprising a first frame 1 and a second frame 2, and also comprising: a monitoring ring 4 and a vibration sensor 7 for detecting vibration of a drive shaft of an electromechanical device, two groups of touch plates 12 are symmetrically arranged in the monitoring ring 4, and the touch plates 12 are fitted to the surface of the drive shaft of the electromechanical device; In this embodiment, the electromechanical equipment to be detected, the first frame 1 and the second frame 2 are fixedly installed on the monitoring platform so that the driving shaft of the above-mentioned electromechanical equipment passes through the monitoring ring 4, and the suction cup feet 31 at the bottom of the first frame 1 and the second frame 2 are adjusted so that the monitoring ring 4 is concentric with the driving shaft of the electromechanical equipment to ensure the accuracy of subsequent monitoring data.

[0022] Specifically, the bottoms of the first frame 1 and the second frame 2 are both provided with an adjustable foot structure, including a suction cup foot 31, the suction cup foot 31 is connected to a foot rod 32, the foot rod 32 and the first frame 1 and the second frame 2 are all threadedly connected, and an adjusting nut (33) is provided on the surface of the foot rod (32), and the distance between the suction cup foot 31 and the bottom surface of the first frame 1 can be driven by rotating the foot rod 32, and after adjustment, the adjusting nut (33) is locked to change the height of the first frame 1 and the second frame 2, so as to adjust the concentricity of the detection device and the drive shaft of the electromechanical device to be tested.

[0023] A connecting rod 3 is connected between the first frame 1 and the second frame 2 , a monitoring ring 4 is arranged between the first frame 1 and the second frame 2 , a second connecting block 29 is arranged in an annular equidistant array on the outer surface of the monitoring ring 4 , and the connecting rod 3 is connected through the second connecting block 29 .

[0024] In this embodiment, a second connecting block 29 is provided on the outer wall of the monitoring ring 4, and the connecting rod 3 connects the first frame 1, the second frame 2 and the monitoring ring 4 through the second connecting block 29, which not only reduces the dead weight of the entire monitoring device, but also provides more space for operators to perform monitoring operations.

[0025] There is a limit sleeve 11 in a circular equidistant array inside the monitoring ring 4, a first spring 10 is arranged inside the limit sleeve 11, and a touch rod 8 is slidably connected inside the limit sleeve 11, a touch plate 12 is fixedly connected to the bottom end of the touch rod 8, and sliding grooves are symmetrically opened on both sides of the limit sleeve 11. A limiter 9 is fixedly installed on the surface of the touch rod 8, and the protrusions on both sides of the limiter 9 are slidably connected to the sliding groove.

[0026] Specifically, a limit sleeve 11 is set in the monitoring ring 4, and the touch rod 8 is elastically connected to the limit sleeve 11 through the first spring 10. The electromechanical equipment and the vibration sensor 7 are started. If the driving shaft of the electromechanical equipment vibrates during rotation, the touch plate 12 and the touch rod 8 will slide vertically back and forth in the limit sleeve 11 during vibration.

[0027] The top of the touch rod 8 passes through the limit sleeve 11 and extends to the outside of the limit sleeve 11. The top of the limit sleeve 11 is pinned with a pressure rod 13. A mounting plate 15 is fixedly installed on the top of the second frame 2. Two groups of vertical plates 14 are fixedly installed on the mounting plate 15. The pressure rod 13 is pinned between the two groups of vertical plates 14 in the center position. The vibration sensor 7 is fixedly installed on the mounting plate 15, and one end of the pressure rod 13 is fitted with the contact of the vibration sensor 7.

[0028] Specifically, in this embodiment, since the rotation of the drive shaft generates vibration, the touch plate 12 is pushed as the drive rotates, thereby driving the touch rod 8 to slide up and down in the limit sleeve 11. When the touch rod 8 slides vertically, it drives the pressure rod 13 to rotate around the pin connection center in the vertical plate 14, thereby triggering the vibration sensor 7 to sense and record monitoring data.

[0029] A load ring 5 is used to provide load to the driving shaft of the electromechanical equipment. The load ring 5 has load wheels 16 in an annular equidistant array therein. The load ring 5 has a vibration sleeve 18 in an annular equidistant array therein. The vibration sleeve 18 has a screw 19 threadedly connected thereto. One end of the screw 19 is rotatably connected to a wheel seat 17. The load wheel 16 is rotatably connected to the wheel seat 17.

[0030] In this embodiment, a load ring 5 is provided on one side of the monitoring ring 4, and a load is applied to the drive shaft by using the load wheel 16 in the load ring 5. Vibration monitoring is then performed under the load state. The data collected by the vibration sensor 7 for the second time solves the defect of single monitoring data in the current technology and further improves the accuracy of the monitoring data.

[0031] Two groups of detachable limit shafts 21 are symmetrically arranged on both sides of the wheel seat 17. The top of the limit shaft 21 is threadedly connected to the wheel seat 17. The limit shaft 21 is slidably connected in the load ring 5. A second spring 20 is symmetrically connected between the vibration sleeve 18 and the load ring 5.

[0032] Specifically, the screw 19 is rotated to drive the load wheel 16 to fit the surface of the drive shaft of the electromechanical equipment to be tested, and a load is applied to the drive shaft. When the drive shaft is loaded, steps one and two are repeated, and the monitoring data of the vibration sensor 7 is recorded again, thereby performing multi-state monitoring of the vibration frequency of the drive shaft.

[0033] An adjusting shaft 24 and a guide link 28 are connected between the second frame 2 and the load ring 5. The adjusting shaft 24 and the guide link 28 are arranged in a circular equidistant array on the outer wall of the load ring 5. A second connecting block 29 is also provided on the outer wall of the load ring 5. The guide link 28 and the second connecting block 29 are slidably plugged. A first connecting block 22 is provided on the outer wall of the load ring 5. The adjusting shaft 24 runs through the first connecting block 22. Guide sleeves 23 are provided in both the first connecting block 22 and the second connecting block 29.

[0034] In this embodiment, the outer rings of the monitoring ring 4 and the load ring 5 are both provided with a first connecting block 22, and only a group of second connecting blocks 29 are provided on the outer ring of the load ring 5. Guide sleeves 23 are provided in the first connecting block 22 and the second connecting block 29 to facilitate the sliding connection between the guide link 28 and the connecting rod 3 therein, which can not only ensure the structural stability of the monitoring device, but also ensure that the load ring 5 can move on the surface of the guide link 28.

[0035] An adjustment component is arranged between the adjustment shaft 24 and the first connecting block 22, and the adjustment component includes a rack 25 and a gear 26. A slot is opened in the adjustment shaft 24, and the rack 25 is fixedly installed in the slot. The gear 26 is rotatably installed in the first connecting block 22 through an adjustment rod 27. The rack 25 and the gear 26 are meshed, and a damping bearing is arranged between the adjustment rod 27 and the first connecting block 22.

[0036] In this embodiment, when it is necessary to adjust the position of the load ring 5 on the surface of the drive shaft, the gear 26 is rotated and the rack 25 is moved. Since the rack 25 is fixedly installed in the groove of the adjustment shaft 24, and the first connecting block 22 and the load ring 5 are fixedly connected, the gear 26 can drive the load ring 5 to produce a certain displacement, thereby adapting to drive shafts of different lengths.

[0037] A linkage plate 30 is fixedly installed on one side of the outer wall of the limit sleeve 11. The linkage plate 30 is inclined at one end of the limit sleeve 11. Adjustment rings 6 are provided on the outer sleeves of the two groups of linkage plates 30. The adjustment rings 6 are set to a conical ring structure. The inner wall of the adjustment ring 6 and the inclined surface of the linkage plate 30 are slidably fitted, and the adjustment ring 6 and the load ring 5 are fixedly connected.

[0038] In this embodiment, after the load wheel 16 and the drive shaft are fitted, the adjustment component is used to change the position of the load ring 5 on the surface of the drive shaft. Since a guide shaft 34 is provided through the second frame 2, the horizontal section of the linkage plate 30 and the guide shaft 34 are slidably connected. Therefore, when the load ring 5 moves, the adjustment ring 6 pressurizes the two groups of linkage plates 30 to drive the limit sleeve 11 to move downward, thereby driving the touch plate 12 and the drive shaft to fit and compact.

[0039] In the present invention, when in use, the electromechanical device to be tested, the first frame 1 and the second frame 2 are fixedly installed on the monitoring platform, so that the driving shaft of the electromechanical device passes through the monitoring ring 4, the adjustment ring 6 and the load ring 5 in sequence, and the suction cup support feet 31 at the bottom of the first frame 1 and the second frame 2 are adjusted. Specifically, the support foot rod 32 is rotated to drive the distance between the suction cup support feet 31 and the bottom surface of the first frame 1, change the height of the first frame 1 and the second frame 2, and adjust the concentricity of the detection device and the driving shaft of the electromechanical device to be tested; The electromechanical device and the vibration sensor 7 are started at the same time. If the driving shaft of the electromechanical device generates vibration during the rotation process, the vibration will drive the pressure rod 13 to rotate around the pin connection center in the vertical plate 14 through the touch plate 12 and the touch rod 8, thereby triggering the vibration sensor 7 to sense. As the driving rotation pushes the touch plate 12, the touch rod 8 is driven to slide up and down in the limit sleeve 11. When the touch rod 8 slides vertically, it drives the pressure rod 13 to rotate around the pin connection center in the vertical plate 14, thereby triggering the vibration sensor 7 to sense and record the monitoring data. The screw 19 is rotated to drive the load wheel 16 to fit the surface of the drive shaft of the electromechanical equipment to be tested, and a load is applied to the drive shaft. When the drive shaft is loaded, steps 1 and 2 are repeated, and the monitoring data of the vibration sensor 7 is recorded again, thereby performing multi-state monitoring on the vibration frequency of the drive shaft. Specifically, the screw 19 is rotated to drive the load wheel 16 to fit the surface of the drive shaft of the electromechanical equipment to be tested, and a load is applied to the drive shaft. When the drive shaft is loaded, steps 1 and 2 are repeated, and the monitoring data of the vibration sensor 7 is recorded again, thereby performing multi-state monitoring on the vibration frequency of the drive shaft.

[0040] A monitoring method comprises the following steps: Step 1: The electromechanical device to be tested, the first frame 1 and the second frame 2 are fixedly mounted on the monitoring platform, so that the driving shaft of the electromechanical device passes through the monitoring ring 4, the adjustment ring 6 and the load ring 5 in sequence, and the suction cup feet 31 at the bottom of the first frame 1 and the second frame 2 are adjusted so that the monitoring ring 4 is concentric with the driving shaft of the electromechanical device; Step 2: Start the electromechanical device and the vibration sensor 7 at the same time. If the driving shaft of the electromechanical device generates vibration during the rotation process, the pressure rod 13 is driven to rotate around the pin connection center in the vertical plate 14 through the touch plate 12 and the touch rod 8, thereby triggering the vibration sensor 7 to sense and record the monitoring data; Step 3: Rotate the screw 19 to drive the load wheel 16 to fit the surface of the drive shaft of the electromechanical equipment to be tested, apply load to the drive shaft, and repeat steps 1 and 2 when the drive shaft is loaded, and record the monitoring data of the vibration sensor 7 again, so as to perform multi-state monitoring of the vibration frequency of the drive shaft.
