[0027] Example

[0028] In the existing technology, for underground conveyor belt equipment that is out of the sight of the operators, the operating status of the conveyor belt cannot be controlled during actual operation. If the conveyor belt malfunctions and stops running, or if the personnel neglect to turn it on, it is easy to cause material accumulation, which can lead to equipment damage.

[0029] Please see Figures 1-5 This utility model provides a technical solution: a conveyor belt operation status monitoring device, including a conveyor belt body, a monitoring component on one side of the conveyor belt body; and an alarm component, which is used to remind personnel of the operation status of the conveyor belt body.

[0030] To facilitate the disassembly of contactor 22 and avoid disassembly in confined spaces that could affect disassembly efficiency, the monitoring component includes a mounting base 9, a mounting bracket 11, and a sensor 13. The mounting bracket 11 is mounted on the top of the mounting base 9, and the sensor 13 is mounted on the mounting bracket 11 with a nut. A groove 14 is provided on the top of the mounting base 9. A limit block 15 is mounted on one end of the groove 14, and a pull post 16 is slidably connected to the other end of the groove 14. One end of the pull post 16 is fixedly connected to one side of the limit block 15. Located inside the slide groove 14, the pull column 16 is fixedly connected to the inner side of the slide groove 14 with a telescopic spring 17. The top of the mounting bracket 11 is provided with a slot 18, and the limiting block 15 is engaged inside the slot 18. By pushing the pull column 16 to move inside the slide groove 14, the pull column 16 drives the limiting block 15 to move to one end of the slide groove 14. At this time, one end of the limiting block 15 is disengaged from the top of the mounting bracket 11, and the mounting bracket 11 can be lifted upwards and moved. The mounting seat 9 is disengaged from the inside of the positioning groove 12, thus completing the disassembly of the mounting bracket 11.

[0031] When installing the contactor 22, one end of the slot 18 of the mounting bracket 11 is pressed against the inclined surface at the top of the limiting block 15. By pressing down the mounting bracket 11, the limiting block 15 is pushed to move. At this time, the telescopic spring 17 is compressed. When the limiting block 15 is pressed against the top of the mounting base 9, the telescopic spring 17 drives the pull column 16 to reset, so that the limiting block 15 is engaged with the top of the mounting bracket 11, thus completing the installation of the sensor 13, saving time and effort.

[0032] The top of the mounting base 9 is fixedly connected with two positioning posts 10. The mounting frame 11 has positioning slots 12 on both sides. The two positioning posts 10 are engaged inside the positioning slots 12. During installation, the positioning slots 12 on the mounting frame 11 are moved to the outside of the positioning posts 10 to facilitate the installation of the mounting frame 11.

[0033] The conveyor belt body includes a fixed frame 1, two rotating shafts 2, and two toothed discs 3. The two rotating shafts 2 are rotatably connected to the inner ends of the fixed frame 1, and the two toothed discs 3 are fixedly sleeved on the outer ends of the rotating shafts 2 and located inside the fixed frame 1. Chains 4 are connected to the outer sides of the two toothed discs 3 on one side, and connecting plates 5 are installed between the chains 4. A conveyor belt 6 is installed on the outer side of the connecting plates 5. Several convex shafts 8 are installed on one side of the chains 4, and a drive motor 7 is installed on one side of the fixed frame 1. The output shaft of the drive motor 7 is fixedly connected to one end of the rotating shaft 2 extending to the outer side of the fixed frame 1. The output shaft of the drive motor 7 drives the toothed discs 3 on the rotating shaft 2 to rotate, and the toothed discs 3 drive the conveyor belt 6 to rotate through the chains 4. The conveyor belt 6 can move the material, and during the rotation of the chains 4, it also drives the several convex shafts 8 to rotate.

[0034] Mounting base 9 is installed on one side of fixed frame 1. The center line of sensor 13 coincides with the center line of cam shaft 8. The alarm component includes control box 19, PLC module 20 and control relay 21. PLC module 20 is installed inside control box 19. Control relay 21 is installed inside control box 19 and below PLC module 20. Contactor 22 is installed inside control box 19 on one side of control relay 21. Audible and visual alarm 23 is installed on top of control box 19. Dynamic indicator light 24 is set on top of control box 19 on one side of audible and visual alarm 23. Sensor 13 utilizes the uneven state between cam shaft 8 and chain 4. After the conveyor belt body is running, there is a continuous and stable pulse signal. After stopping, the signal is normally open or normally closed to activate audible and visual alarm 23, thereby completing the monitoring of the conveyor belt body and eliminating the accumulation of waste material after the conveyor belt body stops, which may cause equipment damage. At the same time, when the conveyor belt body is running normally, dynamic indicator light 24 is flashing. When the conveyor belt body stops running, dynamic indicator light 24 is turned off to confirm the running status of the conveyor line.

[0035] The electrical signal output terminal of sensor 13 is connected to the electrical signal input terminal of PLC module 20. The electrical output terminal of PLC module 20 is connected to the electrical input terminal of control relay 21. The electrical output terminal of control relay 21 is connected to the electrical input terminal of contactor 22. The electrical output terminal of contactor 22 is connected to the electrical input terminals of audible and visual alarm 23 and dynamic indicator light 24, respectively. The model of sensor 13 is E2E-X10D1-NZ; the model of PLC module 20 is CP2E-E30DR-A; the model of control relay 21 is MY2N-GS24VDC; the model of contactor 22 is CAD32BDC24VDC; and the model of audible and visual alarm 23 is JD150PB-L04YT0112W122.

[0036] The working principle or structural principle is as follows: When the conveyor belt body is in use, the drive motor 7 is started by controlling the switch group. The output shaft of the drive motor 7 drives the toothed disc 3 on the rotating shaft 2 to rotate. The toothed disc 3 drives the conveyor belt 6 to rotate through the chain 4. The conveyor belt 6 can move the material. During the rotation of the chain 4, several cam shafts 8 are also driven to rotate. The sensor 13 takes advantage of the uneven state between the cam shafts 8 and the chain 4. After the conveyor belt body is running, there is a continuous and stable pulse signal. After stopping, the signal is normally open or normally closed to activate the audible and visual alarm 23, thereby completing the monitoring of the conveyor belt body and eliminating the accumulation of waste material after the conveyor belt body stops, which may cause equipment damage. At the same time, when the conveyor belt body is running normally, the dynamic indicator light 24 is in a flashing state. When the conveyor belt body stops running, the dynamic indicator light 24 is turned off to confirm the operating status of the conveyor line.

[0037] When sensor 13 needs to be disassembled for maintenance, by pushing pull column 16 to move inside slide groove 14, pull column 16 drives limit block 15 to move to one end of slide groove 14. At this time, one end of limit block 15 is disengaged from the top of mounting bracket 11, and mounting bracket 11 can be lifted upwards and moved. Mounting seat 9 is disengaged from inside positioning groove 12, thus completing the disassembly of mounting bracket 11, which facilitates the disassembly of contactor 22. When installing contactor 22, move positioning groove 12 on mounting bracket 11 to the outside of positioning column 10, and then one end of slot 18 of mounting bracket 11 abuts against the inclined surface at the top of limit block 15. By pressing down mounting bracket 11, limit block 15 is pushed to move. At this time, telescopic spring 17 is compressed. When limit block 15 abuts against the top of mounting seat 9, telescopic spring 17 drives pull column 16 to reset, so that limit block 15 is engaged with the top of mounting bracket 11, thus completing the installation of sensor 13, saving time and effort.
