[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0020] according to Figure 1-4 As shown, this embodiment proposes a mechanical roller bearing damage detection device, including bearing bodies 3 disposed at both ends of the central shaft 2 of the mechanical roller 1. A set of bearing bodies 3 are provided with an assembly rod 4 on one side of the inner end face. The assembly rod 4 is provided with an assembly bolt 5. The assembly rod 4 is connected to the assembly hole on the inner end face of the set of bearing bodies 3 through the assembly bolt 5. A sensing iron plate 6 is provided on the end face of the mechanical roller 1 near the assembly rod 4. A through groove is provided at the lower end of the assembly rod 4. An installation sleeve 7 is provided in the through groove. A movable rod 8 is detachably installed in the installation sleeve 7. Each movable rod 8 is provided with a scale 9. The movable rod 8 can move within the installation sleeve 7. The length of movement can be indicated by the scale 9 to improve the accuracy of movement. A proximity switch 10 is provided below the end of the movable rod 8 near the sensing iron plate 6. The proximity switch 10 is connected to one end of the movable rod 8, and the wire of the proximity switch 10 is electrically connected to the PLC control cabinet.
[0021] When the mechanical roller bearing damage detection device of this utility model detects the damage status of the bearing body 3, it first controls the installation position of the proximity switch 10 to ensure that the sensing iron plate 6 is within its sensing distance. When the mechanical roller 1 rotates, the proximity switch 10 receives the sensing signal fed back by the sensing iron plate 6 in real time. When the bearing body 3 is damaged, causing the rotation speed of the central shaft 2 to decrease or stop (the mechanical roller 1 and the central shaft 2 rotate synchronously), the proximity switch 10 will transmit the received sensing signal to the PLC control cabinet. The PLC control cabinet will issue a corresponding alarm to indicate that the bearing body 3 is damaged.
[0022] The assembly rod 4 includes a fixing rod 401 and a sleeve 402. The fixing rod 401 has multiple fixing holes 403. The sleeve 402 is fitted over the outside of the fixing rod 401, and a fixing bolt 404 is mounted on the sleeve 402, connecting to the fixing holes 403. The fixing rod 401 and sleeve 402 of this invention constitute a telescopic rod, enabling the proximity switch 10 mounted on the assembly rod 4 to be adjusted in position and height, resulting in high device flexibility.
[0023] An adjusting bolt 11 is provided on the lower outer wall of the sleeve 402. The mounting sleeve 7 has a mating hole adapted to the adjusting bolt 11. The movable rod 8 has multiple adjusting holes 12, and the adjusting bolt 11 is connected to each adjusting hole 12. The movable rod 8 of this invention can move within the mounting sleeve 7, thereby making the distance between the sensing surface of the proximity switch 10 and the sensing iron plate 6 adjustable. Specifically, this is achieved by moving the movable rod 8 and then connecting the adjusting bolt 11 to the corresponding adjusting hole 12.
[0024] The proximity switch 10 has a connecting sleeve 13 on its top, which is sleeved onto one end of the movable rod 8. The connecting sleeve 13 is provided with a fastening bolt 14, which is connected to the movable rod 8. This arrangement allows the proximity switch 10 to be quickly assembled and disassembled.
[0025] Example 2
[0026] according to Figure 1-4 As shown, this embodiment proposes a mechanical roller bearing damage detection device, including bearing bodies 3 disposed at both ends of the central shaft 2 of the mechanical roller 1. A set of bearing bodies 3 is provided with an assembly rod 4 on one side of the inner end face. The assembly rod 4 is provided with an assembly bolt 5. The assembly rod 4 is connected to the assembly hole on the inner end face of the set of bearing bodies 3 through the assembly bolt 5. A sensing iron plate 6 is provided on the end face of the mechanical roller 1 near the assembly rod 4. A through groove is provided at the lower end of the assembly rod 4. An installation sleeve 7 is provided in the through groove. A movable rod 8 is detachably installed in the installation sleeve 7. Each movable rod 8 is provided with a scale 9. A proximity switch 10 is provided below the end of the movable rod 8 near the sensing iron plate 6. The proximity switch 10 is connected to one end of the movable rod 8, and the wire of the proximity switch 10 is electrically connected to the PLC control cabinet.
[0027] The assembly rod 4 includes a fixing rod 401 and a sleeve 402. The fixing rod 401 is provided with fixing holes 403. There are multiple fixing holes 403. The sleeve 402 is sleeved on the outside of the fixing rod 401. The sleeve 402 is provided with fixing bolts 404. The fixing bolts 404 are connected to the fixing holes 403.
[0028] The lower end of the sleeve 402 is provided with a through threaded hole 15, the position of which is adapted to the position of the wire of the proximity switch 10, and a conduit 16 is connected inside the through threaded hole 15. The bottom of the mounting sleeve 7 is provided with a support base 17, and multiple support bases 17 are provided, each with a through hole adapted to the diameter of the conduit 16. This invention, by providing a through threaded hole 15 at the lower end of the sleeve 402 and controlling the position of the through threaded hole 15 to be adapted to the position of the wire of the proximity switch 10, allows the conduit 16 to be installed inside the through threaded hole 15, while the wire of the proximity switch 10 can be led out from the conduit 16, thus protecting the wire from sagging and affecting the normal operation of the mechanical roller 1.
[0029] This invention involves setting an induction plate 6 on the end face of the mechanical roller 1, installing an assembly rod 4 on the inner end face of the bearing body 3, and detachably installing a movable rod 8 in the mounting sleeve 7 at the lower end of the assembly rod 4. A proximity switch 10 adapted to the induction plate 6 is installed at one end of the movable rod 8. The proximity switch 10 enables real-time sensing and monitoring of the rotation speed of the induction plate 6, thereby monitoring the operating status of the bearing body 3 and determining whether the bearing body 3 has been damaged. The monitoring process can be carried out synchronously and in real-time while the mechanical roller 1 is running, which is highly convenient and can play a role in protecting the stable operation of the mechanical roller 1.
