[0028] like Figures 1 to 5As shown, a rotating machinery fault diagnosis device includes: a worktable 1, with a support member 2 and a cover plate 101 respectively on the top of the worktable 1. The support member 2 is used to support the rotating parts; a limiting member 4 is set on the top of the cover plate 101 to limit the rotating parts; and a detection member 3 is set on the top of the worktable 1 to detect faults in the rotating parts. Specifically, during use, the rotating parts to be diagnosed are first placed on the top of the worktable 1, and then the rotating parts are limited by the cooperation of the support member 2 and the limiting member 4 to ensure the stability of the position of the rotating parts during the diagnosis process. Finally, the rotating parts are diagnosed by the detection member 3. The cover plate 101 can cover the rotating parts during use to prevent the rotating parts from falling from the top of the worktable 1. A drive box is also provided on the outside of the worktable 1, which can provide power to the rotating parts during use.

[0029] like Figures 1 to 5 As shown, an observation window is also provided on the outside of the cover plate 101. Specifically, the observation window is made of transparent acrylic material to ensure that the operator can observe the rotation status of the rotating parts in a timely manner. The cover plate 101 is connected to the worktable 1 by a hinge.

[0030] like Figures 1 to 5 As shown, the support component 2 includes multiple adjusting blocks 201, which are arranged in a straight line along the length of the worktable 1. Each adjusting block 201 has a support roller 202 on its top. Specifically, the adjusting blocks 201 can drive the support rollers 202 to move in opposite directions during use. The adjusting blocks 201 and the worktable 1 can be connected by bolts or slots, so that they can provide support for rotating parts of different lengths in conjunction with the support rollers 202 during use. The opposing support rollers 202 can be driven by a bidirectional thread or a gear rack.

[0031] like Figures 1 to 5As shown, the limiting component 4 includes a sliding sleeve 401, and there are multiple sliding sleeves 401. The sliding sleeves 401 are positioned directly above the adjusting block 201. The axis of the sliding sleeve 401 is parallel to the height direction of the worktable 1. A guide rod 402 is slidably connected inside the sliding sleeve 401, and the guide rod 402 passes through the cover plate 101. A pressure roller 404 is provided at the end of the sliding sleeve 401 relative to the worktable 1. A spring 403 is also sleeved on the outside of the guide rod 402. Specifically, when diagnosing the rotating part, the rotating part is first placed on top of the support roller 202, and then the cover plate 101 is closed. While closing the cover plate 101, the pressure roller 404 presses the rotating part from the top to ensure the rotating part is properly diagnosed. For stability during the process, the pressure roller 404 is positioned directly above the rotating part. The sliding sleeve 401 guides the movement direction of the guide rod 402 and provides support for it, ensuring that the pressure roller 404 and the guide rod 402 can move linearly along the sliding sleeve 401. The spring 403 provides tension to the guide rod 402 during use, allowing the pressure roller 404 to press the rotating part. The sliding sleeve 401 and the cover plate 101 can be connected by bolts or clips. The number and position of the sliding sleeves 401 can be selected according to the size and length of the rotating part, so that the pressure roller 404 can stably limit the rotation of the part during use.

[0032] like Figures 1 to 5As shown, the testing component 3 includes multiple adjusting frames 301, which slide on the top of the workbench 1. A support rod 302 is slidably connected to the outer side of the adjusting frame 301. One end of the support rod 302 has an arc-shaped block 303, and both ends of the arc-shaped block 303 have sliding grooves 305. A connecting rod 304 is slidably connected inside the sliding grooves 305. A limiting rod 306 is provided on the outer side of the connecting rod 304. Both ends of the connecting rod 304 have telescopic grooves 307, and telescopic rods 308 are slidably connected inside the telescopic grooves 307. A testing component is provided on the outer side of the telescopic rod 308. The measuring rod 309 slides inside the arc-shaped block 303. Specifically, during use, the position and height of the arc-shaped block 303 are adjusted by the cooperation of the adjusting bracket 301 and the support rod 302. Then, the distance between the opposite ends of the measuring rod 309 is adjusted by the cooperation of the connecting rod 304 and the arc-shaped block 303, ensuring that the measuring rod 309 can stably diagnose the rotating part during use. A non-contact eddy current sensor for diagnosing the rotating part is provided at the opposite end of the measuring rod 309. The contact eddy current sensor can monitor the center trajectory of a rotating component during use. The shaft center trajectory diagram is a set of vibration signals monitored from two mutually perpendicular directions on the same cross section of the journal. Based on the shape of the detected shaft center trajectory diagram, the specific cause of the vibration can be analyzed, and early signs of faults can be obtained, which has a guiding role in preventing the fault from worsening and troubleshooting. The limit rod 306 can control the position of the connecting rod 304 relative to the support rod 302 during use, preventing the connecting rod 304 from moving relative to the support rod 302 during detection. The axis of the detection rod 309 is perpendicular to the axis. The telescopic groove 307 can guide the telescopic rod 308 during use, ensuring that the telescopic rod 308 can slide stably inside the telescopic groove 307, thereby synchronously adjusting the spacing of the detectors during use. The arc block 303 can guide the detection rod 309 during use, ensuring that the detection rod 309 can move stably during use. There are no restrictions on the shape of the detection rod 309, which can be cylindrical, square columnar, or hexagonal prism, etc.

[0033] like Figures 1 to 5 As shown, the telescopic rod 308 is also equipped with a locking rod inside, and the locking rod abuts against the detection rod 309. Specifically, the locking rod and the telescopic rod 308 are connected by threads, so that the detection rod 309 can be controlled by the contact and separation of the locking rod and the detection rod 309 during use.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
