Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection, in particular to a rolling bearing multi-sensor detection platform. Background Art

[0002] Rolling bearings are key components in mechanical equipment, transmitting motion and bearing loads. Their operating status directly affects the reliability and lifespan of the entire machine. Currently, condition monitoring and fault diagnosis of rolling bearings, particularly collecting vibration signals at their mounting locations (bearing seats), are a common and effective method for assessing their health.

[0003] However, in the prior art, vibration detection of bearing seats usually involves magnetically attaching multiple independent vibration detectors to the outer surface of the bearing seat in a point-by-point manner. This method has significant shortcomings: first, the selection of detection points and the placement of sensors mainly rely on the operator's experience, and the position distribution is often uneven and difficult to accurately control, resulting in the collected vibration signal being unable to fully and evenly reflect the true state of the bearing seat in the circumferential direction, seriously affecting the accuracy and comparability of the detection results; second, each sensor needs to be individually positioned and attached, and the installation process is cumbersome and time-consuming; after the detection is completed, they need to be disassembled and recycled one by one, which is inefficient, especially in situations where space is limited or frequent detection is required.

[0004] Therefore, there is an urgent need for a rolling bearing multi-sensor detection platform to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings mentioned in the above background technology, the present invention provides a rolling bearing multi-sensor detection platform.

[0006] The technical solution is: a rolling bearing multi-sensor detection platform, including a mounting block, a hinge, a locking bolt, a pressure plate, a lifting frame and a vibration sensor. The mounting block is arranged in a semicircular shape, and the two mounting blocks are formed into a circular mounting ring through the hinge. The two mounting blocks are locked by the locking bolt and the locking nut to maintain the mounting ring state. During detection, the mounting ring is sleeved on the bearing seat, and the main shaft to be detected is installed in the bearing seat through the rolling bearing. Eight mounting grooves are evenly spaced on the mounting block, of which four evenly spaced mounting grooves are fixedly installed with pressure plates, and the mounting grooves with pressure plates are slidably connected with lifting frames. A vibration sensor is fixedly installed on each lifting frame, and the detection end of the vibration sensor is set toward the bearing seat. When the lifting frame moves downward, the detection end of the vibration sensor is in contact with the surface of the bearing seat, so as to perform vibration detection on the rolling bearing on the bearing seat.

[0007] Furthermore, it also includes a connecting plate, a guide rod, a lifting plate, a hinged rod, a cleaning plate, a scraper block and a connecting spring. The lower part of each vibration sensor is fixedly installed with a connecting plate, and two guide rods are slidably connected to the connecting plate. A lifting plate is fixedly connected between the bottoms of the two guide rods, and two connecting springs are connected between the lifting plate and the connecting plate. The two connecting springs are both sleeved on the corresponding guide rods. The cleaning plate is slidably connected inside the lifting plate, and hinged rods are hingedly connected between the two sides of the cleaning plate and the corresponding two sides of the connecting plate. A scraper block is fixedly installed on the side of the bottom of the cleaning plate close to the mounting block. A through hole for the vibration sensor to pass through is opened on the cleaning plate directly below the vibration sensor. When the lifting frame drives the vibration sensor and the connecting plate to move downward, the scraper block contacts the surface of the bearing seat, and the cleaning plate slides out from the inside of the lifting plate under the pushing force of the hinged rod.

[0008] Furthermore, it also includes a driven gear, a transmission gear, a rack, a gear ring and a drive assembly. A driven gear is rotatably installed on the middle part of each pressure plate through a rotating shaft, and a transmission gear is fixedly installed on the rear side of the driven gear through a rotating shaft. A rack is fixedly installed on the front side of each lifting frame, and the transmission gear is meshed with the rack. Semi-circular gear rings are slidably installed on the front of the two mounting blocks. When the two mounting blocks are combined into a mounting ring, the two semi-circular gear rings are combined into a circular gear ring, and the gear ring is meshed with each driven gear. A driving assembly for driving the gear ring to rotate is provided on one of the mounting blocks.

[0009] Furthermore, the driving assembly includes a servo motor and a driving gear, wherein the servo motor is fixedly mounted on the front of one of the mounting blocks, the driving gear is fixedly mounted on the output shaft of the servo motor, and the driving gear is meshed with the gear ring.

[0010] Furthermore, the scraper is made of plastic.

[0011] Furthermore, the sliding connections between the gear ring and the mounting block are coated with grease.

[0012] The beneficial effects of the present invention are as follows: 1. The present invention combines two semicircular mounting blocks into a circular mounting ring structure, and utilizes mounting grooves and pressure plates evenly spaced thereon to ensure the precise positioning and equidistant distribution of vibration sensors and lifting frames in the circumferential direction of the bearing seat. This rigid and uniform layout enables all vibration sensors to contact the detection surface at the same time and at equal distances, and the collected vibration signals can more comprehensively and evenly reflect the true status of each point on the circumference of the bearing seat, fundamentally solving the influence of sensor position deviation on the detection results, and greatly improving the accuracy, reliability and comparability of rolling bearing vibration detection.

[0013] 2. This utility model utilizes two hinged mounting blocks and a locking bolt structure to quickly assemble and disassemble the inspection platform. Operators simply close the two unfolded mounting blocks around the bearing seat and secure them with the locking bolts to complete the installation of the entire platform. To disassemble, loosen the locking bolts and hinge the mounting blocks for easy removal. This "embracing" design significantly simplifies the operation process and significantly reduces installation and disassembly time. It is particularly suitable for applications where space is limited or frequent inspections are required, greatly improving inspection efficiency.

[0014] 3. In the process of the vibration sensor being driven downward by the lifting frame, the plastic scraper will contact the surface of the bearing seat before the sensor, and the cleaning plate will slide out under the push of the hinged rod, automatically scraping off the oil and foreign matter at the detection point, providing a clean contact surface for the vibration sensor, ensuring that signal collection is not interfered with by pollution, and improving data accuracy.

[0015] 4. This utility model uses a single servo motor to drive the driving gear, which in turn drives the combined gear ring, which in turn drives all driven gears and transmission gears synchronously, ultimately driving all racks and lifting frames to rise and fall synchronously. This design not only achieves automatic and synchronous compression and lifting of all vibration sensors, eliminating the trouble of individual adjustments and ensuring consistent contact pressure, but also, combined with the buffering effect of the connecting spring, ensures smooth and reliable sensor contact and smooth deployment and retraction of the scraper.

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Embodiment: A rolling bearing multi-sensor detection platform, such as Figure 1-Figure 5 As shown, it includes a mounting block 4, a hinge 5, a locking bolt 6, a pressure plate 7, a lifting frame 8 and a vibration sensor 9. The mounting block 4 is arranged in a semicircular shape. The two mounting blocks 4 form a circular mounting ring through the hinge 5. The two mounting blocks 4 are locked together by the locking bolt 6 and the locking nut 601 to maintain the mounting ring state. During the inspection, the mounting ring is sleeved on the bearing seat 1, and the main shaft 3 to be inspected is installed in the bearing seat 1 through the rolling bearing 2. Eight mounting grooves 401 are evenly spaced on the mounting block 4, of which four evenly spaced mounting grooves 401 are fixedly installed with pressure plates 7, and the mounting grooves 401 with the pressure plates 7 are all slidably connected with lifting frames 8. A vibration sensor 9 is fixedly installed on each lifting frame 8, and the detection end of the vibration sensor 9 is set towards the bearing seat 1. When the lifting frame 8 moves downward, the detection end of the vibration sensor 9 is in close contact with the surface of the bearing seat 1, so as to perform vibration detection on the rolling bearing 2 on the bearing seat 1. In addition, the four evenly spaced mounting grooves 401 can be used to set the mounting pressure plate 7 and the lifting frame 8 according to the detection needs, so as to install the sound detector to cooperate with the vibration sensor 9 for synchronous detection, thereby improving the comprehensiveness of the detection of the rolling bearing 2. The sliding connection between the gear ring 21 and the mounting block 4 is coated with grease. The coated grease effectively reduces the friction resistance and ensures the smoothness of the driving process.

[0026] like Figure 5 and Figure 6As shown, it also includes a connecting plate 10, a guide rod 11, a lifting plate 12, a hinged rod 13, a cleaning plate 14, a scraper 1401 and a connecting spring 15. The lower part of each vibration sensor 9 is fixedly installed with a connecting plate 10 by means of bolts. Two guide rods 11 are slidably connected to the connecting plate 10. A lifting plate 12 is fixedly connected between the bottoms of the two guide rods 11. Two connecting springs 15 are connected between the lifting plate 12 and the connecting plate 10. The two connecting springs 15 are both sleeved on the corresponding guide rods 11. The cleaning plate 14 is slidably connected to the inside of the lifting plate 12. The two sides of the cleaning plate 14 are hingedly connected to the corresponding two sides of the connecting plate 10 with hinged rods 13. A scraper 1401 is fixedly installed on one side of the bottom of the plate 14 near the mounting block 4. A through hole for the vibration sensor 9 to pass through is opened on the cleaning plate 14 directly below the vibration sensor 9. When the lifting frame 8 drives the vibration sensor 9 and the connecting plate 10 to move downward, the scraper 1401 contacts the surface of the bearing seat 1. Under the pushing force of the hinged rod 13, the cleaning plate 14 slides out from the inside of the lifting plate 12 to clean the surface of the bearing seat 1. After the cleaning plate 14 slides out, it will no longer block the through hole on the cleaning plate 14, so that the vibration sensor 9 can pass more smoothly. The scraper 1401 is made of plastic material to facilitate better cleaning of the surface of the bearing seat 1.

[0027] like Figure 3 and Figure 5 As shown, it also includes a driven gear 18, a transmission gear 19, a rack 20, a gear ring 21 and a drive assembly. A driven gear 18 is rotatably installed on the middle part of each pressure plate 7 through a rotating shaft, and a transmission gear 19 is fixedly installed on the rear side of the driven gear 18 through a rotating shaft. A rack 20 is fixedly installed on the front side of each lifting frame 8, and the transmission gear 19 is engaged with the rack 20. A semi-circular gear ring 21 is slidably installed on the front part of the two mounting blocks 4. When the two mounting blocks 4 are combined into a mounting ring, the two semi-circular gear rings 21 are combined into a circular gear ring, and the gear ring is engaged with each driven gear 18. A driving assembly for driving the gear ring 21 to rotate is provided on one of the mounting blocks 4.

[0028] like Figure 1 、 Figure 2 、 Figure 3 and Figure 7 As shown, the driving assembly includes a servo motor 22 and a driving gear 23 , wherein the servo motor 22 is fixedly mounted on the front of one of the mounting blocks 4 , and the driving gear 23 is fixedly mounted on the output shaft of the servo motor 22 , and the driving gear 23 is meshed with the gear ring 21 .

[0029] When it is necessary to use this device to perform vibration detection on the rolling bearing 2 in the bearing seat 1, first, the operator unfolds the two semicircular mounting blocks 4 through the hinge 5 and places them around the outside of the bearing seat 1. Then, the operator closes the two mounting blocks 4 so that they are combined into a complete annular mounting ring through the hinge 5, and uses the locking bolt 6 and the locking nut 601 to firmly lock the two mounting blocks 4 to ensure that the mounting ring is stably mounted on the bearing seat 1. At this time, the main shaft 3 to be tested has been installed inside the bearing seat 1 through the rolling bearing 2. Then, the operator starts the servo motor 22, and the servo motor 22 drives the driving gear 23 on its output shaft to rotate. Since the driving gear 23 is engaged with the gear ring 21, and after the two mounting blocks 4 are combined, the two semi-circular ring gears 21 thereon are also combined into a complete annular gear ring. Therefore, the rotation of the driving gear 23 drives the entire gear ring to rotate synchronously, and the rotation of the gear ring 21 drives the four driven gears 18 engaged with it to rotate, thereby driving the transmission gear 19 to rotate. The rotation of the transmission gear 19 drives the rack 20 engaged with it to move downward. The downward movement of the rack 20 drives the entire lifting frame 8 to slide downward along the mounting groove 401. The downward movement of the lifting frame 8 drives the vibration sensor 9 and the connecting plate 10 fixed thereon to move downward together. The downward movement of the connecting plate 10 is driven by the two guide rods 11 The movable lifting plate 12 moves downward. When the lifting frame 8 continues to move downward, first, the plastic scraper 1401 fixed to the bottom of the cleaning plate 14 will contact the surface of the bearing seat 1. As the lifting frame 8 continues to move downward, the connecting plate 10 continues to move downward relative to the scraper 1401 and the cleaning plate 14 that are blocked by the contact with the surface of the bearing seat 1. At this time, the hinged rod 13 connected between the two sides of the cleaning plate 14 and the corresponding two sides of the connecting plate 10 starts to move, generating a driving force, forcing the cleaning plate 14 to overcome the friction and slide out from the inside of the lifting plate 12. After the cleaning plate 14 slides out, it no longer blocks the through hole on the cleaning plate 14, allowing the vibration sensor 9 to pass through the through hole smoothly. During this process, the scraper 1401 moves on the surface of the bearing seat 1, scraping off oil or foreign matter in its contact area, providing a clean contact surface for the upcoming vibration detection. At the same time, the connecting spring 15 is compressed to store energy.

[0030] When the vibration sensor 9 moves down with the lifting frame 8 to its detection end and finally comes into close contact with the surface of the bearing seat 1 that has been cleaned by the scraper 1401, the lifting frame 8 stops moving down, and the vibration sensor 9 is in the optimal working position, and can begin to accurately collect and detect the vibration signal of the rolling bearing 2 on the bearing seat 1 during operation.

[0031] After the inspection is completed, the operator controls the servo motor 22 to reverse, driving the driving gear 23 to reverse, thereby driving the gear ring 21 to reverse, and the gear ring 21 reverses to drive the driven gear 18 and the transmission gear 19 to reverse, thereby driving the rack 20 and the lifting frame 8 to slide upward and reset. The lifting frame 8 rises and drives the vibration sensor 9 and the connecting plate 10 to rise. At this time, the compressed connecting spring 15 releases energy, pushing the lifting plate 12 to move downward a short distance relative to the connecting plate 10. At the same time, as the connecting plate 10 rises, the tension of the hinged rod 13 causes the cleaning plate 14 to retract with the scraper 1401 into the lifting plate 12, restoring the initial state. Finally, loosen the locking bolt 6, open the two mounting blocks 4 through the hinge 5, and the entire inspection platform can be removed from the bearing seat 1.
