Detailed implementation manners

[0026] The following illustrates the implementation manners of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0027] Existing vibration sensors are generally installed in parts such as the motor housing or the belt conveyor frame that are in a state of long-term vibration. However, the existing installation methods of vibration sensors generally adopt methods such as bolt connection, magnetic adsorption installation, or welding installation. However, these methods are either cumbersome to install and not easy to disassemble and maintain, or are easy to move or even fall off under long-term vibration.

[0028] To solve this problem, please refer to Figures 1-5 , a data acquisition device for belt conveyor monitoring that is easy to maintain, including:

[0029] Vibration sensor 10, mounting plate 31, and fixing component 20 arranged outside the threaded column 32.

[0030] A circular ring 11 is fixedly arranged on the outer side of the vibration sensor 10, and at least two groups of limiting holes 12 are opened on the circular ring 11. A threaded column 32 is fixedly arranged on the bottom of the mounting plate 31, and at least one group of plug rods 33 is fixedly arranged on the bottom of the mounting plate 31. The fixing assembly 20 includes an inner ring 21 and at least two groups of plug plates 24. The inner ring 21 is threadedly connected with the threaded column 32. An elastic member 22 is arranged on the outer side of the inner ring 21. An outer ring 23 is slidably arranged on the outer side of the inner ring 21. The end of the elastic member 22 away from the inner ring 21 is fixedly connected to the inner top of the outer ring 23. At least two groups of plug plates 24 are fixedly arranged at the bottom of the inner ring 21, and a socket 25 corresponding to the plug rod 33 is opened on the top of the outer ring 23.

[0031] The limiting assembly 40 disposed in the plugging plate 24 is used to limit the plugging plate 24 when it is inserted into the limiting hole 12 so that the plugging plate 24 cannot be separated by itself.

[0032] When in use, the mounting plate 31 is fixed to the belt conveyor where monitoring is required, the insert plate 24 is aligned with the limiting hole 12, the insert plate 24 is inserted into the limiting hole 12, and the ring 11 is limited by the limiting component 40 in the insert plate 24, so that the insert plate 24 will not be separated from the limiting hole 12, the outer ring 23 is held by hand to be pulled down and rotated, and the elastic member 22 is compressed when the outer ring 23 descends, and the inner ring 21 is driven to rotate by the outer ring 23. The inner ring 21 moves upward when rotating due to the threaded column 32, and the inner ring 21 drives the vibration sensor 10 to rotate and move upward through the insert plate 24 and the limiting hole 12. When the inner ring 21 rotates to the top of the threaded column 32, the ring on the vibration sensor 10 11, because the plug plate 24 is pulled upward by the limit assembly 40, the upper end surface of the ring 11 is in close contact with the top of the threaded column 32, thereby completing the fixation of the vibration sensor 10. When the inner ring 21 rotates to the top of the threaded column 32, the plug rod 33 is located directly above the socket 25. The outer ring 23 is loosened, and the elastic member 22 pushes the outer ring 23 to move upward, so that the plug rod 33 is inserted into the socket 25, so that the outer ring 23 does not rotate when it is vibrated. When maintaining the vibration sensor 10, the outer ring 23 is pulled downward to enable it to rotate, thereby driving the vibration sensor 10 to descend, and canceling the limit of the limit assembly 40 on the limit hole 12, thereby completing the disassembly of the vibration sensor 10.

[0033] In the specific implementation process, Figure 4 As shown, the limit assembly 40 includes at least one group of sliders 42 and elastic members 43. A slide groove 41 is provided in the plug plate 24. The slider 42 is slidably arranged at the bottom of the slide groove 41. The elastic member 43 is fixedly arranged on one side of the slider 42. A limit pin 44 is fixedly arranged on the other side of the slider 42. The end of the elastic member 43 away from the slider 42 is fixedly connected to the inner wall of the slide groove 41.

[0034] During use, push the end of the limit pin 44 to move it into the chute 41. The limit pin 44 drives the slider 42 to move and compress the second elastic member 43, so that the insertion plate 24 can be inserted into the limit hole 12. When the limit pin 44 passes through the limit hole 12, release the extrusion on the end of the limit pin 44. The second elastic member 43 pushes the end of the limit pin 44 out again through the slider 42, so that the pushed-out limit pin 44 blocks when the insertion plate 24 is disengaged from the limit hole 12, and the vibration sensor 10 is connected to the insertion plate 24 through the limit hole 12.

[0035] In a specific implementation process, such as Figure 3 and Figure 4 shown, a dial plate 45 is fixedly arranged on the slider 42, and the dial plate 45 penetrates through the outer surface of the insertion plate 24.

[0036] When it is necessary to cancel the limitation of the limit pin 44 on the ring 11, push the dial plate 45 in the direction opposite to the penetrating end of the limit pin 44. The dial plate 45 drives the limit pin 44 to move into the chute 41 through the slider 42, so that the insertion plate 24 will not be blocked when disengaging from the limit hole 12, and the vibration sensor 10 is separated from the insertion plate 24.

[0037] In a specific implementation process, such as Figure 3 shown, the end of the limit pin 44 penetrates through the outer surface of the insertion plate 24, and the bottom of the end of the limit pin 44 penetrating through the insertion plate 24 is arc-shaped.

[0038] During use, the penetration of the limit pin 44 enables it to block when the insertion plate 24 is disengaged from the limit hole 12. The end of the limit pin 44 is arc-shaped, so that its bottom can move into the chute 41 by itself under the extrusion force when being extruded, thus facilitating the insertion of the insertion plate 24 into the limit hole 12.

[0039] In a specific implementation process, such as Figure 4 shown, a collar 34 that rotates along its own axis is arranged at the bottom outside the threaded column 32. At least one group of limit blocks 35 is fixedly arranged on the outside of the collar 34. The limit blocks 35 penetrate through the chute 41 and are slidably connected within the chute 41.

[0040] During use, when the insertion plate 24 rotates, the collar 34 is driven to rotate through the limit blocks 35. The limit blocks 35 inside the chute 41 will slide within the chute 41 due to the rotation of the inner ring 21. When the inner ring 21 is located at the top of the threaded column 32, the limit blocks 35 are in front of the moving direction of the dial plate 45 and block it, so that the dial plate 45 cannot be pushed, and thus the limit pin 44 cannot move into the chute 41, preventing the vibration sensor 10 from detaching due to vibration.

[0041] In a specific implementation process, such as Figure 3As shown, at least one set of ribs 26 is fixedly arranged on the outer side of the inner ring 21, and at least one set of rib grooves 27 is formed at the inner opening of the top of the outer ring 23. The ribs 26 are slidably connected within the rib grooves 27.

[0042] During use, with the ribs 26 and the rib grooves 27, the outer ring 23 can move up and down on the outer side of the inner ring 21. However, when the outer ring 23 rotates, the inner ring 21 can be driven to rotate together through the ribs 26 and the rib grooves 27.

[0043] In a specific implementation process, as Figure 2 shown, there are at least two sets of mounting holes 311 formed in the mounting plate 31. Bolts 312 are inserted into the mounting holes 311. Washers 313 are sleeved on the bolts 312, and nuts 314 are threadedly arranged on the bolts 312. The washers 313 are located between the bolts 312 and the nuts 314.

[0044] When installing and fixing the mounting plate 31, insert the bolts 312 into the mounting holes 311, pass the bolts 312 through the reserved holes at the connection part to be connected, sleeve the washers 313 on the bolts 312, and then screw the nuts 314 into the top of the bolts 312, thereby fixing the mounting plate 31 at the monitoring location through the bolts 312 and the nuts 314.

[0045] In a specific implementation process, as Figure 3 shown, the first elastic member 22 is a spring, and the spring is sleeved on the outer side of the inner ring 21.

[0046] The first elastic member 22 can be an ordinary spring, which is just sleeved on the outer side of the inner ring 21. This design enables the outer ring 23 to be pushed upward when released, and when the outer ring 23 is vibrated, it will always push the outer ring 23 upward, preventing the insertion rod 33 from disengaging from the insertion hole 25.

[0047] In a specific implementation process, as Figure 4 shown, the chute 41 is arc-shaped, and the second elastic member 43 is an arc-shaped spring. The arc-shaped spring is horizontally arranged within the chute 41.

[0048] During use, the first elastic member 22 can be an ordinary arc-shaped spring, which is horizontally arranged within the arc-shaped chute 41. This design enables it to effectively push the slider 42 to move smoothly within the arc-shaped chute 41.

[0049] In a specific implementation process, as Figure 1 and Figure 2 shown, the threaded column 32 penetrates through the outer ring 23, and anti-slip strips 28 are arranged on the outer side of the outer ring 23.

[0050] During use, the penetration of the threaded post 32 ensures that the outer ring 23 is not affected by the threads outside the threaded post 32 when rising or falling. The anti-slip strips 28 on the outside of the outer ring 23 prevent slipping when holding the outer ring 23 and rotating it.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
