Description

Technical Field

[0001] The utility model belongs to the technical field of bearings, and particularly relates to a device for detecting minute vibrations on the surface of a bearing. Background Art

[0002] A bearing is an important component used to support mechanical rotation. It usually consists of an inner ring, an outer ring, rolling elements (such as spheres or rollers), and a cage (such as a cage, sleeve, etc.). Their basic function is to reduce friction between mechanical components, make rotation smoother, and support the operation of the bearing under specific loads and speeds.

[0003] According to a disclosed vibration detection device (publication number: CN211085468U), it includes a main control module, a communication module, a sensor detection module, a power supply module, and a GPS positioning module; the communication module, the sensor detection module, the power supply module, and the GPS positioning module are respectively electrically connected to the main control module. The sensor detection module includes a vibration sensor for collecting vibration source signal data; the power supply module includes a rechargeable battery for continuously powering the device. However, in the above device, through the cooperation of components such as the sensor detection module, the power supply module, and the GPS positioning module, it is difficult to achieve the effect of fixing the bearing, and it is difficult to ensure that it will not cause data inaccuracy due to movement or loosening during the detection process, increasing the accidental situations caused by the movement of the bearing, and there is room for improvement. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a device for detecting minute vibrations on the surface of a bearing. Through the cooperation of the force driving the fixed plate by the electric telescopic rod and components such as the support frame, the fixed block, and the baffle in the fixing device, the effect of driving the fixed block to displace through the displacement of the support frame and driving the baffle to displace through the displacement of the fixed block is achieved, solving the existing problems.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a device for detecting minute vibrations on the surface of a bearing, including a protective plate. A bearing is arranged on the top of the protective plate, and a vibration sensor is arranged on the top of the protective plate;

[0007] A fixing device is arranged on the top of the protective plate. The fixing device includes an electric telescopic rod. The bottom of the electric telescopic rod is fixedly connected to the top of the protective plate. The telescopic end of the electric telescopic rod is fixedly connected to a fixed plate. A rotating rod is rotatably connected to the side of the fixed plate. One end of the rotating rod away from the fixed plate is rotatably connected to a support frame. A fixed block is fixedly connected to the top of the support frame. A baffle is fixedly connected to the side of the fixed block.

[0008] Further, the number of the rotating rods is set to two, and they are symmetric with respect to the vertical central axis of the protective plate. The number of the fixed blocks is set to two, and they are symmetric with respect to the vertical central axis of the protective plate. The above design can firmly fix the bearing in the set position, ensuring that it will not cause data inaccuracy due to movement or loosening during the detection process. This stability is crucial for accurately detecting the subtle vibrations on the surface of the bearing.

[0009] Further, a support plate is fixedly connected to the top of the protective plate. A hydraulic cylinder is fixedly connected to the side of the support plate. One end of the hydraulic cylinder is slidably connected to a force-receiving rod through a piston, and the other end of the hydraulic cylinder is slidably connected to a hydraulic rod through a piston. The bottom of the hydraulic rod is fixedly connected to a pressing plate, and one end of the force-receiving rod is fixedly connected to a force-receiving plate.

[0010] Further, a spring is fixedly connected to the side of the hydraulic cylinder. The end of the spring away from the hydraulic cylinder is fixedly connected to the circumferential surface of the force-receiving rod. The initial state of the spring is a relaxed state. The above design is beneficial to reset the force-receiving rod through the elastic force of the spring, and can effectively reduce the unexpected situations caused by the movement of the bearing.

[0011] Further, a fixing frame is fixedly connected to the top of the protective plate. A mounting block is fixedly connected to the side of the fixing frame. A positioning block is fixedly connected to the side of the fixing plate. The side of the positioning block is slidably connected to the side of the mounting block. By controlling the downward pressure of the pressing plate through the hydraulic system, it can ensure that the bearing is in a horizontal state. This correction can eliminate the instability caused by the uneven installation of the bearing, ensuring that the vibration sensor can accurately and stably detect the subtle vibrations on the surface of the bearing.

[0012] Further, a slideway is fixedly connected to the top of the fixing frame. A slider is fixedly connected to the bottom of the support frame. The side of the slider is slidably connected to the top of the slideway. Using the hydraulic system for position correction can effectively control the application of force, avoiding damage or unnecessary pressure to the bearing and the equipment. At the same time, this design makes the operation simple, and the operator can relatively easily adjust and control the correction process.

[0013] Further, a pressing rod is fixedly connected to the side of the support frame. A limiting block is fixedly connected to the top of the fixing frame. The limiting block is located on the movement track of the support frame. Since the bearing is correctly fixed and kept horizontal, the detected vibration data is more credible and comparable, which is very important for predicting the life of the bearing and can help the operator take necessary measures in time.

[0014] The utility model has the following beneficial effects:

[0015] The utility model drives the fixing plate through the electric telescopic rod, and the force of displacement is matched with components such as the support frame, fixing block and baffle in the fixing device, realizing the displacement of the fixing block driven by the displacement of the support frame and the displacement of the baffle driven by the displacement of the fixing block, achieving the effect of fixing the bearing, ensuring that the data is not inaccurate due to movement or loosening during the detection process, and effectively reducing accidents caused by the movement of the bearing.

[0016] The utility model drives the extrusion rod through the displacement of the support frame, and the force of displacement is matched with components such as the stress plate, hydraulic rod and hydraulic cylinder in the fixing device, realizing the displacement of another piston driven by the liquid inside the hydraulic cylinder, the piston driving the hydraulic rod to displace, and the hydraulic rod driving the pressing plate to displace downward, achieving the effect of correcting the position of the bearing by pressing the pressing plate, ensuring that the bearing is in a horizontal state and preventing the detection data from being affected.

[0017] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] A spring 219 is fixedly connected to the side of the hydraulic cylinder 216. The end of the spring 219 away from the hydraulic cylinder 216 is fixedly connected to the circumferential surface of the force-receiving rod 218. The initial state of the spring 219 is a relaxed state. The above design is beneficial to reset the force-receiving rod 218 through the elastic force of the spring 219, and can effectively reduce accidents caused by the movement of the bearing 102.

[0032] A fixing frame 213 is fixedly connected to the top of the protective plate 101. A mounting block 212 is fixedly connected to the side of the fixing frame 213.

[0035] A specific application of this embodiment is as follows: In this application, the electric telescopic rod 201 drives the fixed plate 209 to displace, causing the fixed plate 209 to drive the positioning block 211 to displace along the mounting block 212.

The support frame 203 drives the slider 207 to displace along the slideway 206. Then, the displacement of the support frame 203 drives the fixed block 204 to displace. The displacement of the fixed block 204 drives the baffle 205 to displace, achieving the function of fixing the bearing 102. Then, the displacement of the support frame 203 drives the extrusion rod 215 to displace. The extrusion rod 215 extrudes the force-bearing plate 220 to displace. Then, the force-bearing plate 220 extrudes the force-bearing rod 218, causing the force-bearing rod 218 to displace inward to extrude the piston inside the hydraulic cylinder 216. The piston inside the hydraulic cylinder 216 pushes the liquid inside it. The liquid inside the hydraulic cylinder 216 pushes another piston to displace. The piston pushes the hydraulic rod 217 to displace. The hydraulic rod 217 pushes the pressing plate 221 to displace downward, achieving the function of correcting the position of the bearing 102 by pressing down the pressing plate 221, ensuring that the bearing 102 is in a horizontal state and preventing the influence on the detection data. At this time, the vibration sensor 103 on the side of the bearing 102 detects the bearing 102.
