[0028] The middle position of the support plate 4 is threadedly connected to the movable rod 3, and the two ends of the support plate 4 are slidably connected to the limit rod 2, and the support plate 4 and the bracket 1 form a relative lifting structure, and the lifting distance of the support plate 4 is equal to the farthest distance from the fixed block 5 to the bracket 1. When the movable rod 3 rotates, it can drive the support plate 4 to do lifting movement, so that the diagnostic mechanism 17 can be driven to rise and fall synchronously to change the height;

[0029] There are two first bevel teeth 7, and one of the first bevel teeth 7 is meshed with the second bevel tooth 8, and the second bevel tooth 8 and the fan blade 9 are coaxially arranged. At the same time, the first bevel tooth 7 and the support plate 4 are coaxially arranged. When the first bevel tooth 7 rotates, the fan blade 9 can be driven to rotate by the second bevel tooth 8 meshed with it, so that the wind force generated can dissipate the heat generated when the device is running;

[0030] The rubber sleeve 13 and the docking block 16 inside the support frame 12 are connected through a spherical joint, and the rubber sleeve 13 and the rubber pad 15 are in contact, and the support frame 12 forms a sliding structure through the slider 11 and the movable groove 10, and the docking block 16 can be rotated to different angles in the support frame 12 for adjusting the angle of the diagnostic mechanism 17;

[0031] An oil storage box 18 is fixed on the bracket 1 on the side of the movable rod 3, and a bamboo oil nozzle 19 is provided at one end of the oil storage box 18, and an oil inlet pipe 20 is connected to the other end of the oil storage box 18, and the end of the oil inlet pipe 20 and the bottom of the movable rod 3 are extended to the inside of the oil storage cavity 24, and an oil collecting port 21 is opened on the bracket 1 on the side of the oil storage box 18, and a filter screen 22 is fixed on the inner side of the oil collecting port 21, and a one-way valve 23 is provided below the filter screen 22, and the oil collecting port 21 is funnel-shaped, and excess oil in the cooling oil during the transmission process can fall into the oil collecting port 21, and the impurities contained in the cooling oil are filtered through the filter screen 22;

[0033] Working principle: Figure 1-4As shown, before diagnosing the rotating machinery, the position of the diagnostic mechanism 17 needs to be adjusted. Therefore, the two meshing first bevel teeth 7 are driven to rotate by the motor 6, and then the movable rod 3 is driven to rotate synchronously. Since the movable rod 3 and the support plate 4 are threadedly connected, and the support plate 4 can be driven to move up and down through the limit rod 2, the diagnostic mechanism 17 can be driven to move up and down synchronously to change the height. The diagnostic mechanism 17 can slide in the movable groove 10 through the support frame 12 and the slider 11, which can be used to adjust the lateral position of the diagnostic mechanism 17, such as Figure 4 The diagnostic mechanism 17 is connected to the support frame 12 through the docking block 16, so the docking block 16 can be rotated to different angles in the support frame 12 to adjust the angle of the diagnostic mechanism 17. After the adjustment, the locking bolt 14 is rotated to drive the rubber pad 15 to contact the rubber sleeve 13 to ensure the stability of the position of the diagnostic mechanism 17 after the angle adjustment, so as to realize diagnostic operations with different requirements;

[0034] like Figure 3 and Figure 5-6 As shown, when the first bevel gear 7 rotates, the fan blade 9 can be driven to rotate by the second bevel gear 8 meshing therewith, so that the wind force generated can dissipate the heat generated when the device is running, and at the same time, the bamboo oil nozzle 19 transfers the cooling oil in the oil storage box 18 to the fan blade 9. The air-cooling and oil-cooling method can improve the heat dissipation efficiency, and the excess oil in the cooling oil during the transfer process can fall into the oil collecting port 21, and the impurities contained in the cooling oil are filtered through the filter screen 22, and then the excess cooling oil flows into the oil storage chamber 24, and then the movable rod 3 rotates while driving the fixed rod 25 to rotate, and drives the sleeve plate 26 to slide on the fixed rod 25, so that the valve plate 28 can be driven to move horizontally through the guide rod 27, and the cooling oil in the oil storage chamber 24 is pushed from one end to the other end, and then enters the oil storage box 18 from the oil inlet pipe 20, so that the cooling oil can be reused to avoid waste.
