Description

Technical Field

[0001] This utility model relates to the field of testing devices, and in particular to a device for testing the wear of elevator wire ropes. Background Technology

[0002] The elevator wire rope wear detection device consists of sensors, a signal processing unit, a data analysis module, and a display unit. It is a professional device that comprehensively utilizes technologies such as electromagnetic induction, ultrasound, and laser to monitor and analyze the wear condition of elevator wire ropes. Using this device serves two purposes: firstly, it ensures safety by preventing breakage accidents and brake failures caused by wire rope wear, thus avoiding serious safety accidents such as elevator falls; secondly, it improves maintenance efficiency, accurately locates problems, optimizes maintenance plans based on wear data, and meets the stringent regulatory requirements for elevator safety performance and inspection and maintenance, ensuring the legal and compliant operation of elevators.

[0003] Existing elevator wire rope wear detection devices operate on various principles. Among electromagnetic induction devices, fluxgate sensors detect changes in the leakage magnetic field caused by wire rope wear and convert them into electrical signals for analysis. Weak magnetic sensors extract differences in magnetic potential for quantitative detection. Metal magnetic memory flaw detection uses high-precision magnetic field detection equipment to monitor magnetic field anomalies caused by external forces to identify damage. GMI magnetic sensors based on the giant magnetoresistance effect measure the resistance changes of specific alloys under the influence of external magnetic fields to sense potential risks in wire ropes. Ultrasonic testing analyzes changes in the amplitude and phase of ultrasonic waves when they encounter defects or wear in the wire rope to determine the wear condition. Image detection uses cameras to acquire images and compares them with normal images using image processing technology to identify wear marks and their extent.

[0004] In the practical application of current elevator wire rope wear testing devices, a prominent problem has gradually emerged. Due to significant differences in specifications, materials, and structures among the wire ropes used in the elevator industry, existing testing devices lack sufficient versatility and adaptability. This forces operators to frequently change different types of testing equipment to match the varying characteristics of the wire ropes. This process is not only time-consuming and labor-intensive but also highly prone to operational errors. Frequent equipment changes make the testing process cumbersome and complex, significantly impacting the inherent efficiency of elevator wire rope wear testing devices and increasing testing costs, thus hindering the smooth and efficient implementation of testing work.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 An embodiment of this utility model provides an elevator wire rope wear detection device, including a handle 1, a connecting block 2 fixedly connected to the top of the handle 1 for connecting a rotating rod 3, a rotating rod 3 rotatably connected inside the connecting block 2 for rotating a detector 12, a detection component provided at one end of the rotating rod 3, and multiple fixed discs 4 fixedly connected to one end of the rotating rod 3 for fixing the detector 12, a connecting column 5 slidably connected inside each fixed disc 4 for connecting the fixed disc 4 and the detector 12, multiple sliding columns 6 fixedly connected to the outer wall of each connecting column 5, a handle 7 fixedly connected to one end of each connecting column 5 for pulling the connecting column 5, and multiple fixing components provided inside each connecting column 5; Each fixing component includes a fixing pin 8, a limiting plate 9, and a spring 10. The outer wall of each fixing pin 8 is slidably connected to the inside of the connecting column 5 to fix the detector 12. The inner wall of each limiting plate 9 is fixedly connected to the outer wall of the fixing pin 8 to limit the movement range of the fixing pin 8. Each spring 10 is disposed inside the connecting column 5 to provide elastic force to the fixing pin 8. One end of each spring 10 is fixedly connected to the inside of the connecting column 5, and the other end of each spring 10 is fixedly connected to one end of the fixing pin 8. The detection component includes a rotating shaft 11 and a detector 12. Both sides of the rotating shaft 11 are rotatably connected between the fixing discs 4 to provide mechanical support for the rotation of the detector 12. The inner wall of the detector 12 is rotatably connected to the outer wall of the rotating shaft 11 to detect the wire rope.

[0020] Specifically, when maintaining or replacing the detector 12 of the elevator wire rope wear detection device, first hold the handle 7 and apply even force to pull the connecting column 5, which is closely connected to it, out of the rotating shaft 11. As the connecting column 5 is pulled out, the fixing pin 8 slowly retracts into the interior of the connecting column 5. When the fixing pin 8 is fully retracted, it means that the detector 12 has been successfully unlocked. At this time, remove the detector 12 from the equipment. After the old detector 12 is removed, take out the new detector 12, align it with the installation position, and gently push it in until it is securely installed back on the equipment, completing the entire replacement process.

[0021] Reference Figure 4 and Figure 5A retaining ring 13 is fixedly connected to one side of handle 1 to restrict the wire rope. A connecting plate 14 is fixedly connected to one side of retaining ring 13 to connect shaft 15 and retaining ring 13. One end of connecting plate 14 is rotatably connected to shaft 15, providing mechanical support for the opening and closing of retaining ring 13 and retaining ring 17. A connecting plate 16 is fixedly connected to the outer wall of shaft 15 to connect shaft 15 to retaining ring 17. One end of connecting plate 16 is fixedly connected to retaining ring 17 to restrict the wire rope. A retaining ring 19 is provided inside retaining ring 17. For fixing the steel wire rope, multiple springs 18 are provided inside the fixing ring 17 to provide support for the fixing ring 19. One end of each spring 18 is fixedly connected to the inside of the fixing ring 17, and the other end of each spring 18 is fixedly connected to one side of the fixing ring 19. A rotating block 20 is fixedly connected to one side of the fixing ring 13 for connecting the threaded post 21. The threaded post 21 is rotatably connected inside the rotating block 20. A nut 22 is threadedly connected to one end of the threaded post 21 for locking the fixing ring 13 and the fixing ring 17. Multiple fixing plates 23 are provided on the outer wall of the threaded post 21.

[0022] Specifically, first, locate and hold nut 22, rotating it counterclockwise. As nut 22 rotates, fixing ring 13 and fixing ring 27 are successfully unlocked. Next, place the wire rope to be tested inside the two fixing rings 19. When placing it, ensure that the wire rope is centered in the fixing ring 19 to avoid deviation or tilting, thus ensuring the accuracy of subsequent testing. After placing the wire rope, hold threaded post 21 and gently rotate it clockwise. During rotation, ensure that threaded post 21 is precisely rotated between the two fixing plates 23. Finally, hold nut 22 again and tighten it clockwise. As nut 22 is gradually tightened, fixing ring 13 and fixing ring 27 slowly approach and tightly clamp the wire rope until it is firmly fixed, ensuring that the wire rope will not shake or shift during testing, providing a stable foundation for accurate testing.

[0023] Working principle: When using the elevator wire rope wear detection device, first replace the detector 12 with the type required. Then, hold the handle 7 and pull out the connecting post 5 connected to it. After that, the fixing pin 8 retracts into the connecting post 5, partially unlocking the detector 12. Then, remove the detector 12 and reinstall the detector 12 required for use back on the device. Then, the detection work can begin. First, rotate the nut 22 to unlock the fixing ring 13 and fixing ring 2 17. Then, put the wire rope to be tested into the two fixing rings 19. Then, rotate the threaded post 21 between the two fixing plates 23. Then, tighten the nut 22 to fix the fixing ring 13 and fixing ring 2 17. At this point, the installation of the device is complete, and the detection work can begin.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
