Description

Technical Field

[0001] The present invention relates to the technical field of vibrator bearing monitoring, and particularly to a vibrator bearing condition monitoring system and method. Background Technique

[0002] A vibrator is a device attached to a vibrating screen to generate an excitation force and is an important component using mechanical vibration. A vibrator is composed of a bearing and a gear. The bearing can support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. Monitoring the parameters of the bearing is the basis for participating in chart calculation and fault analysis and judgment.

[0003] Currently, most vibration sensors are fixed by threaded connection. However, for the sensors installed in this way, since they are exposed to the outside for a long time, rust is likely to occur at the threaded connection between the sensor and the vibrator. At this time, it may lead to the phenomenon that the vibration sensor is not easily disassembled, and the bottom of the installed sensor is not fixed, which may cause the sensor to shift during operation, thereby resulting in errors in the parameter detection of the bearing.

[0004] In view of the deficiencies of the prior art, the present invention provides a vibrator bearing condition monitoring system, which has the advantages of avoiding the use of threaded fixation that is not conducive to later disassembly and fixing the bottom end of the sensor to increase the accuracy of parameter acquisition, and solves the problems that the use of threaded fixation is not conducive to later disassembly and the bottom end of the sensor is not fixed, resulting in inaccurate parameter acquisition. Summary of the Invention

[0005] To achieve the above object of avoiding the use of threaded fixation that is not conducive to later disassembly and fixing the bottom end of the sensor to increase the accuracy of parameter acquisition, the present invention provides the following technical solution: A vibrator bearing condition monitoring system includes a box body, a driving rod is rotatably connected inside the box body, a bearing is fixedly installed on the surface of the driving rod, a limiting component is fixedly installed inside the box body, and a fixing component is fixedly installed at the bottom inside the box body.

[0006] As an optimization, the number of the driving rods is two, and both ends of the two driving rods respectively penetrate through the front and rear ends of the box body.

[0007] As an optimization, the limiting component includes a limiting tube, which is fixedly installed at the top of the box body. A fixing pin is fixedly installed inside the limiting tube. A rotating block is rotatably connected to the surface of the fixing pin. A fixing sleeve is fixedly installed on the inner wall of the limiting tube. A push rod is slidably connected inside the fixing sleeve. Above the fixing sleeve inside the limiting tube, a hollow tube is fixedly installed. A clamping groove is opened at the top end of the inner wall of the hollow tube. A first spring is fixedly installed on the inner wall of the hollow tube close to one side of the limiting tube. The other end of the first spring is fixedly installed with a trapezoidal block. An electric push rod is fixedly installed inside the trapezoidal block. A limiting block is fixedly installed at the output end of the electric push rod. A sensor body is slidably connected inside the limiting tube.

[0008] As an optimization, the limiting tube is located between two bearings. The sensor body inside the limiting tube can detect the parameters of the two bearings on the left and right sides. The top end of the limiting tube passes through the top end of the box body and extends above the box body.

[0009] As an optimization, the number of the rotating blocks is two, which are symmetrically installed on the left and right sides inside the limiting tube. One ends of the two rotating blocks close to each other are located below the sensor body. The two rotating blocks are pushed during the downward movement of the sensor body, and then drive the limiting block to limit the sensor body.

[0010] As an optimization, the trapezoidal block is slidably connected inside the hollow tube. The electric push rod is electrically connected to a control device. The limiting block is located outside the trapezoidal block, and the fixing of the sensor body by the limiting block can be remotely controlled through the control device.

[0011] As an optimization, the fixing component includes a support rod, which is fixedly installed at the bottom inside the box body. In the middle of the top end of the support rod, a support block is fixedly installed. A fixing rod is fixedly installed on the side wall of the support block. A sliding rod is slidably connected to the surface of the fixing rod. One end of the sliding rod far from the side wall of the support block is fixedly installed with a fixing plate. Side rods are fixedly installed on both sides of the fixing plate. One ends of the side rods close to the middle of the support block are fixedly installed with a second spring. One end of the fixing plate close to the middle of the support block is fixedly installed with a fixing block. Rotating rods are rotatably connected to both sides of the fixing block.

[0012] As an optimization, one end of the sliding rod close to the fixing rod is hollow. The fixing rod is slidably connected inside the sliding rod. A spring is fixedly installed between the fixing rod and the sliding rod. The other end of the second spring far from the side rod is fixedly connected to the rotating rod. The rotating rod rotates towards the center direction of the support block under the elastic force of the second spring, and then fixes the bottom end of the sensor body.

[0013] A method for using an exciter bearing condition monitoring system is as follows: The specific steps of using are as follows:

[0014] S1: Insert the vibration sensor through the installation hole reserved on the box body for preliminary installation of the vibration sensor.

[0015] S2: When installing the vibration sensor, the limiting component will limit the sensor body, and the fixing component will fix the bottom end of the sensor body, so that the vibration sensor will not shift.

[0016] S3: Install the exciter on the vibrating screen according to the model, and install a motor as the driving operation.

[0017] S4: Connect the sensor and the collector in a wired manner, and the platform establishes a long TCP connection with the collector.

[0018] S5: Receive the data information collected by the sensor uploaded by the collector, calculate the corresponding chart information using the corresponding algorithm, and the historical chart records can be queried. Different alarm information is configured according to different models of vibrating screens to achieve fault monitoring.

[0019] The beneficial effect of the present invention is that for the exciter bearing condition monitoring system, after the sensor body is inserted into the inner part of the limiting tube, the two limiting blocks on the left and right sides of the sensor body fix the sensor body under the thrust of the push rod, so that the sensor body is fixed inside the box body. When disassembly is required, the electric push rod is controlled by the control device to shorten, so that the limiting block no longer limits the sensor body, achieving the effects of stable limiting and convenient disassembly, and avoiding the phenomenon that traditional threaded fixing is not convenient for disassembly in the later stage. The inertial mass block at the bottom end of the sensor body that slides downward is clamped inside the support block, avoiding the phenomenon that the vibration sensor itself shifts due to vibration and other reasons during the use of the exciter, and further avoiding the inaccurate detection of bearing parameters.

[0036] Please refer to Figure 6 , the fixing component 5 includes a support rod 51, the support rod 51 is fixedly installed at the bottom inside the box body 1, a support block 52 is fixedly installed in the middle of the top end of the support rod 51, a fixing rod 53 is fixedly installed on the side wall of the support block 52, a sliding rod 54 is slidably connected to the surface of the fixing rod 53, one end of the sliding rod 54 far from the side wall of the support block 52 is fixedly installed with a fixing plate 55, side rods 56 are fixedly installed on both sides of the fixing plate 55, a second spring 57 is fixedly installed at one end of the side rod 56 close to the middle of the support block 52, a fixing block 58 is fixedly installed at one end of the fixing plate 55 close to the middle of the support block 52, rotating rods 59 are rotatably connected to both sides of the fixing block 58, one end of the sliding rod 54 close to the fixing rod 53 is hollow, the fixing rod 53 is slidably connected inside the sliding rod 54, a spring is fixedly installed between the fixing rod 53 and the sliding rod 54, the other end of the second spring 57 far from the side rod 56 is fixedly connected to the rotating rod 59, and the rotating rod 59 rotates towards the center direction of the support block 52 under the elastic force of the second spring 57 to fix the bottom end of the sensor body 412.

[0037] During use, after the sensor body 412 is inserted into the inner part of the limit tube 401, during the downward movement of the sensor body 412, it will push the rotating block 403 to rotate. When the rotating block 403 rotates, it will push the push rod 405 to move upward. When the push rod 405 moves upward, it will push the hypotenuse of the trapezoidal block 409, thereby causing the trapezoidal block 409 to stretch the first spring 408 and move in the direction close to the sensor body 412. When the trapezoidal block 409 moves, it drives the fixed limit block 411 to move in the direction of the sensor body 412, thereby limiting the sensor body 412. When disassembly is required, the output end of the electric push rod 410 is controlled by the control device to shorten, so that the limit block 411 moves away from the sensor body 412 and no longer limits the sensor body 412, achieving the effects of stable limiting and convenient disassembly. After the inertial mass block at the bottom of the downward-sliding sensor body 412 is clamped on the surface of the support block 52 that has moved downward, pressing the sensor body 412 downward will push the four fixed blocks 58 to move towards the edge of the support block 52, so that the bottom end of the sensor body 412 is clamped inside the support block 52. At this time, the four fixed blocks 58 limit the bottom end of the sensor body 412. At the same time, the two rotating rods 59 on both sides of the length direction of each fixed block 58 further limit the sensor body 412 under the elastic force of the second spring 57, avoiding the phenomenon that the vibration sensor itself is displaced due to vibration and other reasons during the use of the vibrator.

[0038] In summary, for this vibrator bearing condition monitoring system, after the sensor body 412 is inserted into the inner part of the limit tube 401, the two limit blocks 411 on the left and right sides of the sensor body 412 fix the sensor body 412 under the thrust of the push rod 405, so that the sensor body 412 is fixed inside the box body 1. When disassembly is required, the electric push rod 410 is controlled by the control device to shorten, so that the limit block 411 no longer limits the sensor body 412, achieving the effects of stable limiting and convenient disassembly, and trying to avoid the phenomenon that traditional screw fixation is not convenient for disassembly in the later stage. The inertial mass block at the bottom of the downward-sliding sensor body 412 is clamped inside the support block 52, avoiding the phenomenon that the vibration sensor itself is displaced due to vibration and other reasons during the use of the vibrator, and further avoiding the phenomenon that the detection of bearing parameters is inaccurate.
