Description

Technical Field

[0001] This utility model relates to the field of industrial machinery and equipment condition monitoring technology, and more specifically to a reflective detection device for a winch shaft rotation mechanism. Background Technology

[0002] In grinding systems in industries such as cement, metallurgy, and power, the screw conveyor (often called a auger) at the bottom of low-speed mills (such as coal mills and slag mills) plays a crucial role in conveying materials out of the mill. As a core transmission component, the proper functioning of the auger shaft directly affects the stability and continuous production of the entire grinding system.

[0003] Currently, the operating status of the auger shaft is typically inspected using the following method: after the equipment is shut down, workers must remove the heavy inspection cover on the hot air box to directly observe the auger shaft. This method has many drawbacks:

[0004] 1. Cumbersome and time-consuming operation: Each inspection requires the disassembly and installation of a large number of bolts and heavy cover plates, resulting in extremely low work efficiency;

[0005] 2. Safety hazards: There is a risk of mechanical injury during disassembly, and there is a risk of hot air or dust being ejected when the equipment is briefly shut down and there is still residual heat and pressure inside.

[0006] 3. Inability to monitor in real time: It is impossible to quickly and intuitively confirm the status during equipment operation. When the auger shaft stops rotating due to blockage, breakage or other reasons, it cannot be detected in time, which may lead to equipment damage or production interruption and economic losses.

[0007] Therefore, there is an urgent need for a device that can monitor the operating status of the winch shaft in real time and intuitively without disassembling the equipment, so as to improve the efficiency and safety of equipment monitoring. Utility Model Content

[0053] Sealing shell 2 is fixedly connected to the bearing housing by screws;

[0055] Rotary connector 4 is rotatably connected to the end panel of the sealing shell 2 away from the rotating shaft 1, and the rotary connector 4 corresponds to the shaft end connector 3;

[0056] The flexible connector 5 has two ends fixed to the shaft end connector 3 and the rotating connector 4 respectively, so that the flexible connector 5 can transmit the rotational power of the shaft end connector 3 to the rotating connector 4.

[0057] Reflector 6 is connected to the rotating connector 4 and is located outside the sealing shell 2.

[0058] See appendix Figure 5 The shaft end connector 3 includes a connector 32 fixed to the end face of the rotating shaft 1 by a first bolt 31. The connector 32 has a connecting sleeve 33. The flexible connector 5 is inserted into the connecting sleeve 33 and is tightened and fixed by a first set screw 34 on the connecting sleeve 33.

[0059] See appendix Figure 2 and attached Figure 3 The rotating connector 4 includes a bearing 41 mounted on the end panel of the sealing shell 2, and a hollow connecting shaft 42 connected to the inner ring of the bearing 41. The hollow connecting shaft 42 passes through both sides of the end panel of the sealing shell 2. The flexible connector 5 is inserted into the hollow connecting shaft 42 and is tightened and fixed by the second set screw 43 on the hollow connecting shaft 42. The second set screw 43 is located outside the sealing shell 2.

[0060] See appendix Figure 4A sealing plate 7 is fastened to the inner wall of the end panel of the sealing shell 2 by a second bolt 71. The sealing plate 7 has a through hole 72 for the hollow connecting shaft 42 to pass through, and a dynamic sealing ring 73 is embedded in the through hole 72.

[0061] To further optimize the above technical solution, sealant is filled between the sealing plate 7 and the inner wall of the end panel of the sealing shell 2.

[0062] To further optimize the above technical solution, the hollow connecting shaft 42 located outside the sealing shell 2 is connected to a sealing nut 44.

[0063] To further optimize the above technical solution, the reflector 6 includes a flat plate 61 fixedly sleeved on the hollow connecting shaft 42. The flat plate 61 is located outside the sealing shell 2, and a reflective strip 62 is fixed on the side surface of the flat plate 61 facing away from the sealing shell 2.

[0066] To further optimize the above technical solution, the transparent cover 8 is made of plexiglass.

[0067] The working principle of this embodiment is as follows:

[0068] When the shaft 1 rotates during equipment operation, the shaft end connector 3 at its end rotates synchronously. The shaft end connector 3 fixes one end of the flexible connector 5 through the connector head 32 and the connecting sleeve 33, thereby transmitting the rotational power of the shaft 1 to the flexible connector 5. The flexible connector 5, as a transmission medium, transmits the rotational motion to the rotating connector 4.

[0069] The hollow connecting shaft 42 of the rotating connector 4 is mounted on the end panel of the sealing shell 2 via a bearing 41. The other end of the flexible connector 5 is inserted into the hollow connecting shaft 42 and secured by a second set screw 43. When the flexible connector 5 rotates, it drives the hollow connecting shaft 42 and the reflector 6 connected thereto to rotate synchronously. The reflector 6 includes a flat plate 61 and a reflective strip 62 fixedly sleeved on the hollow connecting shaft 42. The reflective strip 62 is located outside the sealing shell 2 and generates a clear reflective signal when rotated.

[0070] During equipment operation, staff can visually determine whether the winch shaft is operating normally simply by observing whether the reflective strip 62 continues to rotate from a distance, without disassembling any parts. If the reflective strip 62 stops rotating, it indicates that the winch shaft may have stopped due to blockage, breakage, or other reasons, and should be addressed promptly.

[0071] In addition, the sealing shell 2, sealing plate 7, and dynamic sealing ring 73 ensure the airtightness of the device, preventing dust or hot gas leakage; the transparent cover 8 protects the reflective element 6 from contamination or damage while allowing clear observation. The entire device achieves real-time, safe, and efficient monitoring of the operating status of the winch shaft through mechanical transmission and reflective visual signals.
