DETAILED DESCRIPTION
[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.
[0029] In the description of the present invention, it should be noted that the term "including" and its variations represent open inclusion, that is, "including but not limited to". The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0030] The utility model provides a vibration conveyor amplitude detection device, referring to Figure 1-Figure 3 and Figure 7As shown, it includes a sleeve 1, a push rod 2, a sensor 3 and an output device 5; the sleeve 1 is vertically arranged on the frame 6, and has openings at both ends; the push rod 2 is arranged in the sleeve 1, and the push rod 2 includes a pressure-bearing part, which is arranged below the force-applying part of the vibration groove 7, and the distance between the pressure-bearing part of the push rod 2 and the force-applying part of the vibration groove 7 enables the push rod 2 to move downward when the vibration groove 7 moves downward; the sensor 3 is arranged on the frame 6, below the push rod 2. Specifically, the sleeve 1 and the sensor 3 can be fixed to the outside of the frame 6 of the vibrating conveyor, for example, the sleeve 1 is made of a steel pipe, and the sensor 3 is fixed by a bracket, and the sleeve 1 and the bracket can be fixed on the outside of the frame 6 by welding, and then the push rod is inserted into the sleeve 1, and the sensor 3 is fixed on the bracket. A spring 4 is arranged between the push rod 2 and the sensor 3, one end of the spring 4 is connected to the bottom of the push rod 2, and the other end is connected to the sensor 3; the output device 5 is electrically connected to the sensor 3.
[0031] When the vibration conveyor is working, the vibration groove 7 of the vibration conveyor moves up and down in the vertical direction. When the vibration groove 7 moves downward, the force-applying part of the vibration groove 7 presses downward on the compressed part of the push rod 2, pushing the push rod 2 to move downward, and the push rod 2 presses the spring 4 downward, thereby pressing the sensor 3; when the vibration groove 7 moves upward, the push rod 2 moves upward and resets under the elastic force of the spring 4. The greater the displacement of the vibration groove 7 moving downward, the greater the compression of the spring 4, the greater the force pressing the sensor 3, and the greater the signal collected by the sensor 3. The signal collected by the sensor 3 is output through the output device 5. Through the change of the signal collected by the sensor 3, it can be judged whether the amplitude of the vibration conveyor is within the required range. If the amplitude of the vibration conveyor is not within the required range, the staff can perform timely maintenance on the vibration conveyor to effectively avoid major failures of the vibration conveyor.
[0032] When the vibration groove 7 does not contact the push rod 2, and the compressed part of the push rod 2 is in a free state, the signal output by the sensor 3 is the signal generated by the push rod 2 pressing the spring 4 under the action of gravity, and the spring 4 pressing the sensor 3. During actual use, the signal can be cleared. Preferably, the sensor 3 can use a pressure sensor or a displacement sensor. When the sensor 3 uses a pressure sensor, the output signal is a pressure signal. When the sensor 3 uses a displacement sensor, the output signal is a displacement signal. For the convenience of description, the pressure sensor is used as an example in the description of the following technical solution of the utility model.
[0033] refer to Figure 4As shown, when the vibration conveyor is working, the vibration groove 7 of the vibration conveyor moves up and down in the vertical direction. When the vibration groove 7 vibrates with normal amplitude, it has a center position L0, an upper critical position L1 and a lower critical position L2. When the vibration groove 7 works normally, it vibrates up and down between the upper critical position L1 and the lower critical position L2. The pressure-bearing part of the push rod 2 can be set below the bottom of the vibration groove 7. The bottom of the groove is the force-applying part of the vibration groove 7. The bottom of the groove presses the pressure-bearing part of the push rod 2 and pushes the push rod 2 to move downward. At this time, the center position L0, the upper critical position L1 and the lower critical position L2 of the vibration groove 7 when it vibrates with normal amplitude are the center position L0, the upper critical position L1 and the lower critical position L2 of the bottom of the groove. In order to facilitate the installation of the sleeve 1, the push rod 2 and the sensor 3, a detection plate 71 can also be set on the outside of the vibration groove 7, and the pressure part of the push rod 2 is set below the detection plate 71. The detection plate 71 is the force-applying part of the vibration groove 7. The detection plate 71 presses the pressure part of the push rod 2 and pushes the push rod 2 to move downward. At this time, the center position L0, upper critical position L1 and lower critical position L2 of the vibration groove 7 when it vibrates with normal amplitude are the center position L0, upper critical position L1 and lower critical position L2 of the detection plate 71.
[0034] As a preferred embodiment, the pressure part of the push rod 2 is 1-10mm lower than the center position L0 of the force application part of the vibration groove 7 or 1-3mm lower than the lower critical position L2 of the force application part of the vibration groove 7. For example, the pressure part of the push rod 2 can be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm or 10mm lower than the center position L0 of the force application part of the vibration groove 7; the pressure part of the push rod 2 can also be 1mm, 1.5mm, 2mm, 2.5mm or 3mm lower than the lower critical position L2 of the force application part of the vibration groove 7.
[0035] When the compressed part of the push rod 2 is 1-10mm lower than the center position L0 of the force-applying part of the vibration groove 7, the vibration groove 7 moves downward, pressing the compressed part of the push rod 2, the push rod 2 presses the spring 4, the spring 4 compresses and presses the sensor 3, and the sensor 3 outputs a signal. When the vibration groove 7 moves to the lower critical position L2, the signal output by the sensor 3 is the critical value F0 corresponding to the lower critical position L2. Figure 4 and Figure 5As shown, when the vibration groove 7 vibrates at a normal amplitude, the force-applying part of the vibration groove 7 moves between the upper critical position L1 and the lower critical position L2, and the signal output by the sensor 3 is not greater than the critical value F0. When the rubber strip of the rocker arm 8 ages, the elasticity decreases, and the amplitude of the upward movement of the vibration groove 7 decreases. Under the action of gravity, the amplitude of the downward movement of the vibration groove 7 increases, and the amplitude of the downward movement of the vibration groove 7 exceeds the lower critical position L2. The displacement of the force-applying part pressing the push rod 2 to move downward increases. Correspondingly, the compression of the spring 4 increases, the force on the sensor 3 increases, the output signal is greater than the critical value F0, and the signal output curve fluctuates more. Through the signal curve output by the sensor 3, when it is observed that the output signal ∆t increases for a certain period of time, it indicates that the rubber strip of the rocker arm 8 is aged and needs to be replaced. In this embodiment, the vibration groove 7 can press the push rod 2 by moving slightly downward, and the sensor 3 can monitor the vibration amplitude of the vibration groove 7 in real time.
[0036] When the pressure-bearing part of the push rod 2 is 1-3 mm lower than the lower critical position L2 of the force-applying part of the vibration groove 7, Figure 4 and Figure 6 As shown in the figure, when the vibration groove 7 vibrates at a normal amplitude, the force-applying part of the vibration groove 7 moves between the upper critical position L1 and the lower critical position L2, the compressed part of the push rod 2 is in a free state, and the sensor 3 does not output a signal. When the rubber strip of the rocker arm 8 ages, the elasticity decreases, the amplitude of the upward movement of the vibration groove 7 decreases, and under the action of gravity, the amplitude of the downward movement of the vibration groove 7 increases. At this time, when the vibration groove 7 continues to move downward from the lower critical position L2, its force-applying part contacts the compressed part of the push rod 2, presses the push rod 2, and pushes the push rod 2 to move downward. The push rod 2 presses the spring 4, and the spring 4 compresses and presses the sensor 3, and the sensor 3 outputs a signal. Through the signal curve output by the sensor 3, it is observed that when the sensor 3 continuously outputs a signal for a certain time ∆t, it indicates that the rubber strip of the rocker arm 8 has aged and needs to be replaced.
[0037] In one embodiment of the present invention, reference Figure 1 As shown, the top of the push rod 2 can be directly set below the force-applying part of the vibration groove 7. The pressure-bearing part of the push rod 2 is the top of the push rod 2, which is the part where the force-applying part of the vibration groove 7 contacts the push rod 2. The force-applying part of the vibration groove 7 directly presses the top of the push rod 2 to push the push rod 2 downward. The push rod 2 has a simple structure and is easy to install. Preferably, the top of the push rod 2 can also be set as a spherical surface to prevent the vibration groove 7 from bumping against the push rod 2 when it contacts.
[0038] In one embodiment of the present invention, reference Figure 2As shown, a first roller 21 may also be provided at the top end of the push rod 2, and the first roller 21 is provided below the force-applying part of the vibration groove 7. Specifically, the push rod 2 may be provided below the force-applying part of the vibration groove 7 or outside the vibration groove 7, and the first roller 21 may be provided on the side of the push rod 2 facing the vibration groove 7, so that the first roller 21 is located below the force-applying part of the vibration groove 7. When the first roller 21 is provided at the top end of the push rod 2, the pressure-bearing part of the push rod 2 is the first roller 21. When the vibration groove 7 of the vibrating conveyor descends, the force-applying part of the vibration groove 7 contacts the first roller 21, the first roller 21 rotates, and the first roller 21 rolls and rubs against the force-applying part, which can reduce wear and effectively avoid the problem of detection error caused by wear of the pressure-bearing part of the push rod 2.
[0039] In one embodiment of the present invention, reference Figure 3 As shown, the push rod 2 is arranged outside the vibration groove 7; a first roller 21 is arranged in the middle of the push rod 2, and the first roller 21 is 1-3mm lower than the lower critical position L2 of the force-applying part of the vibration groove 7. For example, the pressure-bearing part of the push rod 2 is 1mm, 1.5mm, 2mm, 2.5mm or 3mm lower than the lower critical position L2 of the force-applying part of the vibration groove 7. A second roller 22 is arranged at the top of the push rod 2, and the second roller 22 is 10-15mm higher than the center position L0 of the force-applying part of the vibration groove 7. For example, the second roller 22 is 10mm, 11mm, 12mm, 13mm, 14mm or 15mm higher than the center position L0 of the force-applying part of the vibration groove 7.
[0040] When the vibration groove 7 vibrates with normal amplitude, the force-applying part of the vibration groove 7 moves between the upper critical position L1 and the lower critical position L2, that is, the force-applying part moves between the first roller 21 and the second roller 22, and does not contact the first roller 21 and the second roller 22. When the rubber strip of the rocker arm 8 ages, the elasticity decreases, and the amplitude of the downward movement of the vibration groove 7 increases. At this time, the force-applying part of the vibration groove 7 can contact the first roller 21, press the first roller 21, and push the top rod 2 to move downward. The top rod 2 presses the spring 4, and the spring 4 compresses and presses the sensor 3, and the sensor 3 outputs a signal. When the sensor 3 continues to output a signal for a certain period of time ∆t, it indicates that the rubber strip of the rocker arm 8 has aged and needs to be replaced. By setting the first roller 21, the vibration amplitude of the vibration groove 7 can be monitored.
[0041] After replacing the rubber strip of the rocker arm 8, the inclination angle of the rocker arm 8 may become larger due to the error between the mounting hole of the rocker arm 8 and the screw hole when installing the rocker arm 8, and the eccentricity generated when replacing the bearing of the transmission system. In order to avoid the inclination angle of the rocker arm 8 being too large, a second roller 22 can be set above the force-applying part of the vibration groove 7 to check the inclination angle of the rocker arm 8. When the inclination angle of the rocker arm 8 becomes larger, when the vibration groove 7 vibrates at a normal amplitude, the upper critical position L1 during actual operation is higher than the design value, and the amplitude of the upward movement of the vibration groove 7 increases. It can be observed that the force-applying part of the vibration groove 7 hits the second roller 22. After replacing the rubber strip of the rocker arm 8, if the force-applying part hits the second roller 22 when the vibration groove 7 vibrates, it indicates that the inclination angle of the rocker arm 8 needs to be adjusted.
[0042] In one embodiment of the present invention, Figure 7 As shown, the output device 5 includes a controller 51 and a display 52, wherein the controller 51 is electrically connected to the sensor 3, and the display 52 is electrically connected to the controller 51. A processing module can be set in the controller 51, and the signal collected by the sensor 3 can be processed by the controller 51 and then output and displayed by the display 52, so that the output curve of the signal collected by the sensor 3 can be conveniently observed, the amplitude state of the vibration groove 7 can be monitored, and the use state of the rubber strip of the rocker arm 8 can be judged.
[0043] In one embodiment of the present invention, Figure 7 As shown, the output device 5 also includes an alarm 53, and the alarm 53 is electrically connected to the controller 51. A judgment module can be set in the controller 51, and the judgment module is pre-set with a maintenance threshold, and the maintenance threshold corresponds to the signal collected by the sensor 3 when the rubber strip of the rocker arm 8 needs to be replaced. When the controller 51 determines that the signal sent by the sensor 3 to the controller 51 is greater than the maintenance threshold, that is, the sensor 3 detects that the rubber strip of the rocker arm 8 is aging, the alarm 53 issues a warning reminder such as sound and light, for example, the alarm 53 emits a prompt sound, or turns on a red warning light, etc., to remind the staff to maintain the vibration conveyor in time.
[0044] In one embodiment of the present invention, Figure 8 As shown, the sleeve 1 is provided with a slide groove 11 extending in the vertical direction. Fig. 9 As shown, the push rod 2 is provided with a slider 23 adapted to the slide groove 11. When in use, the push rod 2 passes through the sleeve 1, and the slider 23 is inserted into the slide groove 11. When the vibration groove 7 presses the push rod 2, the slider 23 moves downward along the slide groove 11. When the spring 4 pushes the push rod 2 upward, the slider 23 moves upward along the slide groove 11, so that the push rod 2 can move up and down in the vertical direction. Preferably, the slide groove 11 extends from one end of the sleeve 1 to the other end, and the slider 23 extends from one end of the push rod 2 to the other end.
[0045] In one embodiment of the present invention, Figure 3 As shown, the bottom of the push rod 2 is provided with a first limit rod 24 into which the spring 4 is inserted, and the sensor 3 is provided with a second limit rod 31 into which the spring 4 is inserted. The first limit rod 24 and the second limit rod 31 can fix the position of the spring 4 to prevent the spring 4 from falling off during use. It can be understood that when the vibration groove 7 descends to press the push rod 2, the length of the first limit rod 24 and the second limit rod 31 cannot interfere with the downward movement of the push rod 2.
[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
