Technical Field

[0001] This utility model relates to the field of rotary kiln support roller technology, specifically to a wear-resistant device for mechanical components. Background Technology

[0002] Rotary kiln support roller adjustment is a professional technology in mechanical engineering that controls the axial movement of the kiln body by adjusting the posture of the support rollers.

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1

[0016] Please see Figure 1 - Figure 6 The present invention provides a wear-resistant device for mechanical parts, comprising: a support roller 1 and a fixing frame 6. The fixing frame 6 has multiple mounting holes on its surface, through which bolts can pass through to fix the fixing frame 6 to the external frame. The surface of the fixed frame 6 is provided with a rotating part, the surface of the rotating part is provided with multiple sets of extrusion parts 8, one end of the extrusion part 8 is provided with a mounting part, and one side of the mounting part is provided with a frame 2; The frame 2 has a graphite block 3 inside, and a snap-fit ​​groove 20 is opened on the surface of the graphite block 3. The outer surface of the frame 2 has multiple threaded grooves 13. Both sides of the frame 2 are provided with snap-fit ​​plates 4. The surface of the snap-fit ​​plate 4 has snap-fit ​​strips 21 that match the snap-fit ​​groove 20. The inner wall of the threaded groove 13 is threaded with bolts 5. One side of frame 2 is equipped with a detection component.

[0017] Furthermore, the rotating component includes a fixed frame 7, a rotating shaft 22 rotatably connected inside the fixed frame 7, and multiple nuts 14; Both ends of the rotating shaft 22 are provided with external threads for mating nuts 14. Both ends of the fixed frame 7 are fixedly connected with frosted rings 15. The end face of the nut 14 is fixedly connected with a second frosted ring 16 that matches the frosted ring 15.

[0018] Specifically, the operator uses a tool to rotate nut 14, causing the fixed frame 7 to rotate on the surface of the rotating shaft 22, thereby adjusting the angle between the frame 2 and the graphite block 3. Then, by rotating nut 14, the operator locks the abrasive ring 15 and abrasive ring 16 together, thereby fixing the fixed frame 7 on the surface of the rotating shaft 22 and achieving a stable connection between the rotating part and the fixed frame 6.

[0019] Furthermore, the extrusion component 8 includes a housing 801, an extrusion column 802 disposed inside the housing 801, and a plurality of springs 803 fixedly connected to the end face of the extrusion column 802. The inner wall of the housing 801 is provided with a sliding groove 804, and a sliding block 805 is slidably connected to the inner wall of the sliding groove 804. One side of the sliding block 805 is connected to the surface of the extrusion column 802. The mounting component includes a connecting frame 12, a plurality of threaded grooves on the outer surface of the frame 2, and bolts 17 threadedly connected to the inner wall of the threaded grooves. The extrusion column 802 is connected to the through hole of the connecting frame 12. One end of the surface of the extrusion column 802 is provided with an external thread. A fixing ring 19 that matches the connecting frame 12 is fixedly connected to the surface of the extrusion column 802. A nut 18 is threadedly connected to the outer surface of the extrusion column 802.

[0020] Specifically, the connecting frame 12 is fixed to the frame 2 by bolt 17. After the extrusion column 802 passes through the connecting frame 12, the nut 18 is tightened by a tool and the retaining ring 19 is used to limit it, so that the extrusion part 8 and the frame 2 form a rigid connection. The spring 803 provides continuous elastic force to push the extrusion column 802 outward. At the same time, the extrusion column 802 moves in conjunction with the sliding block 805 inside the slide groove 804 to ensure the linear movement of the extrusion column 802, so as to push the graphite block 3 inside the frame 2 to continuously contact the support roller 1.

[0021] Furthermore, the detection components include a mounting plate 9 fixedly connected to one side of the frame 2, a distance sensor 10 fixedly connected to one side of the mounting plate 9, and an alarm 11 fixedly connected to the center of the surface of the frame 2.

[0022] Specifically, the distance between the graphite block 3 and the support roller 1 is monitored in real time by the distance sensor 10. When the distance between the graphite block 3 and the support roller 1 is exceeded due to wear, the distance sensor 10 triggers the alarm 11 to remind the staff to replace the graphite block 3. By removing the bolt 5, the snap-on plate 4 on one side of the snap-on plate 4 is disengaged from the snap-on groove 20 on the surface of the graphite block 3, making it easier to remove the graphite block 3. Then, the new graphite block 3 is snapped into the frame 2. After that, the snap-on plate 4 on one side of the snap-on plate 4 is snapped into the snap-on groove 20 on the surface of the graphite block 3. Finally, the bolt 5 is threaded through the reserved hole on the surface of the snap-on plate 4 and threaded into the threaded groove 13 to fix the graphite block 3.

[0023] The workflow for this application is as follows: The mounting holes facilitate the passage of bolts, allowing the fixing frame 6 to be fixed to the external frame. The operator rotates nut 14 with a tool to rotate the fixing frame 7 on the surface of the rotating shaft 22, thereby adjusting the angle between the frame 2 and the graphite block 3. Then, by rotating nut 14 with a tool, the abrasive ring 15 and abrasive ring 16 are locked together, thus fixing the fixing frame 7 on the surface of the rotating shaft 22 and achieving a stable connection between the rotating part and the fixing frame 6. The connecting frame 12 is fixed to the frame 2 by bolt 17. After the extrusion column 802 passes through the connecting frame 12, the nut 18 is tightened by a tool and the retaining ring 19 is used to limit it, so that the extrusion part 8 and the frame 2 form a rigid connection. The spring 803 provides continuous elastic force to push the extrusion column 802 outward. At the same time, the extrusion column 802 moves in conjunction with the sliding block 805 inside the slide groove 804 to ensure the linear movement of the extrusion column 802, so as to push the graphite block 3 inside the frame 2 to continuously contact the support roller 1. At the same time, when the graphite block 3 rubs the surface of the support roller 1, the fine graphite particles will be transferred to the metal surface of the support roller 1 to form an extremely thin solid lubricating film (transfer film) with excellent lubrication performance. By forming a graphite lubricating film, the surface of the tire that is difficult to replace is protected from direct wear. The distance between the graphite block 3 and the support roller 1 is monitored in real time by the distance sensor 10. When the distance between the graphite block 3 and the support roller 1 is worn out and exceeds the threshold, the distance sensor 10 triggers the alarm 11 to remind the staff to replace the graphite block 3.
