Description

Technical Field

[0001] This utility model relates to the field of bearing monitoring technology, and in particular to a bearing fault monitoring device. Background Technology

[0002] Bearing fault detectors primarily diagnose faults through physical signal capture and analysis technology. Common types include vibration signal-based analyzers (which collect vibration data of bearings during operation using accelerometers and combine it with spectrum analysis to identify damage characteristics of the inner ring, outer ring, or rolling elements), oil analysis equipment (which detects the composition and concentration of metal abrasive particles in lubricating oil to determine the degree of wear), acoustic diagnostic instruments (which use ultrasonic or audio sensors to capture abnormal noises during bearing operation and locate early cracks or poor lubrication problems), infrared thermal imagers (which identify overheating or localized wear through abnormal temperature distribution), and motor current analysis systems (which indirectly infer bearing faults by monitoring fluctuations in drive motor current).

[0003] The inventors have discovered at least the following problems in the prior art:

[0004] When using existing bearing fault detectors, users need to hold the test bar and press it after determining the test position so that the probe at the bottom retracts into the sensor before testing can be performed. During the test, the user needs to apply pressure continuously for more than 30 seconds to obtain stable test data, which makes it very inconvenient to use.

[0005] In addition, during testing, it is necessary to test the bearing installed in the bearing housing at multiple positions to ensure the accuracy of the data. However, when testing at different positions, it is easy to forget the positions that have been tested before, which will lead to repeated testing positions.

[0006] Therefore, this solution provides a bearing fault monitoring device to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a bearing fault monitoring device to solve the problems in the prior art that require long-term manual pressing operation, which is inconvenient to use, and that multiple positions are easily missed or repeatedly detected.

[0008] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0009] A bearing fault monitoring device includes a monitor and a sensor. The monitor is connected to the sensor via a connecting line. A probe is embedded in the bottom of the sensor. A receiving mechanism and a magnetic marking mechanism are arranged around the sensor. The receiving mechanism is located above the magnetic marking mechanism. The receiving mechanism includes a receiving tube and a convex ring integral with the receiving tube. The convex ring has snap-fit ​​notches on both sides.

[0010] The magnetic marking mechanism includes a receiving cylinder, a magnetic block embedded at the bottom of the receiving cylinder, and a marking sponge. Two hooks are fixedly connected to the top of the receiving cylinder, and the hooks fit into the notch.

[0011] Both the receiving tube and the receiving cylinder are sleeved around the sensor.

[0012] Preferably, two ear plates are fixedly connected to the top of the convex ring, the ear plates are symmetrically distributed on both sides of the sensor, and limit blocks are fixedly connected to both sides of the bottom end of the receiving tube.

[0013] Preferably, the outer side of each ear plate is threaded with a positioning bolt, and one end of the positioning bolt is fixedly connected with a rubber gasket, which is in contact with the sensor.

[0014] Preferably, the inner wall of the receiving cylinder is provided with a sliding groove, the limiting block slides up and down inside the sliding groove, and the bottom end of the receiving cylinder is provided with an embedding groove for engaging the magnetic block.

[0015] Preferably, the receiving cylinder is internally connected to a linkage rod that slides vertically, and the bottom end of the linkage rod is fixedly connected to a pressure plate.

[0016] Preferably, the receiving cylinder is conical, the imprinting sponge is located below the pressure plate, and the interior of the imprinting sponge is filled with water-soluble red ink.

[0017] Preferably, a barrier ring is also embedded at the bottom of the receiving cylinder, and the barrier ring is located inside the magnetic block.

[0018] The beneficial effects of this utility model are:

[0019] I. This utility model, through the cooperation of the receiving mechanism and the magnetic marking mechanism, when the sensor is close to the bearing seat being tested, the magnetic block is attracted to the surface of the bearing seat. Then, the sensor is pressed again to release it, allowing the probe to retract into the sensor and trigger the detection, and lock the position. Thus, the operator can complete the detection without continuously applying pressure, reducing operator fatigue and improving detection efficiency.

[0020] II. This utility model utilizes the cooperation between the receiving mechanism and the magnetic marking mechanism. The magnetic marking mechanism adopts a conical barrel-shaped receiving cylinder design, with a barrier ring at the bottom to isolate the magnetic block from the probe. During testing, the linkage rod drives the pressure plate to squeeze the marking sponge, forming a visible mark with water-soluble red ink on the outer wall of the bearing. This mark is semi-permanent (it can be wiped away with a wet wipe) and can clearly indicate the tested area, avoiding duplication or omission of the test position. Attached Figure Description

[0030] Please refer to the following. Figures 1 to 5 As shown, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0031] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0032] This utility model provides a bearing fault monitoring device, including a monitor 1 and a sensor 3. The monitor 1 is connected to the sensor 3 through a connecting line 2. A probe 4 is embedded in the bottom of the sensor 3. A receiving mechanism 5 and a magnetic marking mechanism 6 are arranged around the sensor 3. The receiving mechanism 5 is located above the magnetic marking mechanism 6.

[0033] The receiving mechanism 5 includes a receiving pipe 51 and a protruding ring 52 integral with the receiving pipe 51. The protruding ring 52 has snap-fit ​​notches 53 on both sides.

[0034] The magnetic marking mechanism 6 includes a receiving tube 61, a magnetic block 68 embedded at the bottom of the receiving tube 61, and a marking sponge 67. Two hooks 64 are fixedly connected to the top of the receiving tube 61, and the hooks 64 fit into the notch 53.

[0035] Both the receiving tube 51 and the receiving cylinder 61 are sleeved around the sensor 3;

[0036] The monitor 1, sensor 3 and probe 4 constitute the bearing fault detector in the prior art. The sensor 3 is a pulse sensor, and the probe 4 is simply a probe that activates the sensor after it retracts into the sensor 3. At the same time, the probe 4 can also detect the bearing in the bearing housing.

[0037] In a further embodiment, two ear plates 55 are fixedly connected to the top of the convex ring 52, and the ear plates 55 are symmetrically distributed on both sides of the sensor 3. Limiting blocks 54 are fixedly connected to both sides of the bottom end of the receiving tube 51.

[0038] In this embodiment, the limiting block 54 ensures that the receiving mechanism 5 can only be inserted into a portion of the receiving cylinder 61.

[0039] In a further embodiment, the outer side of the ear plate 55 is threaded with a positioning bolt 56, and one end of the positioning bolt 56 is fixedly connected with a rubber gasket 57, which is in contact with the sensor 3.

[0040] In this embodiment, the rotating positioning bolt 56 allows the rubber gasket 57 to clamp the sensor 3, thereby positioning the initial position of the receiving mechanism 5, so as to adapt to probes 4 with different pressing lengths and improve the adaptation range.

[0041] In a further embodiment, the inner wall of the receiving cylinder 61 is provided with a sliding groove 63, the limiting block 54 slides up and down inside the sliding groove 63, and the bottom end of the receiving cylinder 61 is provided with an embedding groove 62 that fits the magnetic block 68.

[0042] In this embodiment, the inside of the embedding groove 62 has a snap-fit ​​block, which can prevent the magnetic block 68 from detaching; the imprinting sponge 67 is located between the two magnetic blocks 68.

[0043] In a further embodiment, a linkage rod 65 is slidably connected up and down inside the receiving cylinder 61, and a pressure plate 66 is fixedly connected to the bottom end of the linkage rod 65.

[0044] In this embodiment, the top end of the linkage rod 65 protrudes a certain distance above the receiving cylinder 61, so that when the bottom end of the protruding ring 52 is attached to the top end of the receiving cylinder 61, the linkage rod 65 and the pressure plate 66 can move downward.

[0045] In a further embodiment, the receiving cylinder 61 is cone-shaped, the imprinting sponge 67 is located below the pressure plate 66, and the interior of the imprinting sponge 67 is adsorbed with water-soluble red ink.

[0046] In this embodiment, the bottom diameter of the receiving cylinder 61 is larger than the top diameter, which can ensure the stability of the magnetic block 68 during adsorption and prevent the magnetic block 68 from getting too close to the probe 4; the ink adsorbed in the imprinting sponge 67 can be imprinted on the outer wall of the bearing, and can be wiped off with a wet wipe after the test is completed; if there is no ink in the imprinting sponge 67, it can be dripped in with a dropper or other tools, and kept half-saturated to avoid excessive overflow.

[0047] In a further embodiment, a barrier ring 69 is also embedded at the bottom of the receiving cylinder 61, and the barrier ring 69 is located inside the magnetic block 68.

[0048] In this embodiment, the barrier ring 69 is used to block the magnetic block 68 and prevent the magnetic block 68 from affecting the probe 4.

[0049] The working principle of this utility model is as follows:

[0050] When testing, the test can be started by pressing the button on the monitor 1. The operator can hold the sensor 3 and align the probe 4 with the desired testing position and press to perform the test. During this process, the magnetic block 68 at the bottom of the receiving tube 61 will be attracted to the bearing seat when it is close to the bearing seat. Pressing at this time will not only move the sensor 3 and probe 4 downward, but also passively insert the receiving tube 51 into the inside of the receiving tube 61. During the insertion process, the hooks 64 on both sides of the top of the receiving tube 61 will be pressed against the inside of the notch 53 and expand outward. When the bottom of the protruding ring 52 is completely attached to the top of the receiving tube 61, the hooks 64 will lock the position of the receiving tube 51. At this time, the probe 4 will also be completely retracted into the inside of the sensor 3 and the monitoring will begin. At this time, the sensor 3 can be released. Due to the attraction of the magnetic block 68, it is not necessary to continuously apply downward pressure to the sensor 3, which makes it more convenient to use.

[0051] When the bottom of the convex ring 52 is in contact with the top of the receiving cylinder 61, the linkage rod 65 will be fully inserted into the inside of the receiving cylinder 61, thereby causing the pressure plate 66 to move down and squeeze the marking sponge 67 below. This causes some of the ink inside the marking sponge 67 to be squeezed out and printed on the surface of the bearing seat, forming a mark. This not only reminds that the bearing seat has been inspected, but also that this position of the bearing seat has been inspected, thus avoiding omissions or duplicate inspections of positions or bearing seats during inspection.

[0052] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
