[0027] In this embodiment, as shown in Figure 7 and Figure 8 As shown, the side wall of the support frame 41 is provided with a cleaning device 8, which includes a sleeve ring 81 inserted into the inner surface of the fixing frame, a brush 82 fixedly connected to the inner surface of the sleeve ring 81, the brush 82 being sleeved on the surface of the steel rope 6, and the brush 82 being used to brush off dust, oil stains and other impurities on the surface of the steel rope 6 during movement of the steel rope 6, so as to avoid the influence of the attachment of impurities on the subsequent detection accuracy. The surface of the support frame 41 is provided with a receiving groove 84, and the sleeve ring 81 is inserted into the inner surface of the receiving groove 84 of the support frame 41. The receiving groove 84 can accommodate the sleeve ring 81. The inner walls of the support frame 41 and the sleeve ring 81 are threadedly connected with a mounting pin 83, and the installation and disassembly of the sleeve ring 81 can be quickly completed through thread connection, so as to facilitate the replacement and maintenance of the brush 82 and the sponge pad 86. The side wall of the sleeve ring 81 is fixedly connected with a connecting ring 85, the inner surface of the connecting ring 85 is fixedly connected with a sponge pad 86, the sponge pad 86 is sleeved on the surface of the steel rope 6, and the sponge pad 86 can further wipe off the small impurities remaining on the steel rope 6, forming a double cleaning effect of first brushing and then wiping with the brush 82, improving the surface cleanliness of the steel rope 6, and ensuring accurate identification of the defects of the steel rope 6 by the detector 3.

[0028] The working principle of this invention is as follows: The detector 1 is connected to the detector 3 via a surface-fixed data cable 2 to ensure stable transmission of the detection signal. The steel rope 6 to be tested is inserted into the detector 3 so that the steel rope 6 is within the detection range. The support device 4 serves as the core support structure. The support frame 41 is located directly below the detector 1, providing a stable foundation for the entire detection process. When adjusting the diameter of the steel rope 6, the main threaded column 45 is rotated to make the main threaded column 45 threadedly connected to the inner wall of the support frame 41. During rotation, the moving block 43 is driven to slide along the groove 42 on the surface of the support frame 41, adjusting the distance between the two rotating rollers 44 until the rubber sleeve 46 on the surface of the rotating rollers 44 fits against the upper and lower ends of the steel rope 6, thus completing the adaptation for steel ropes 6 of different diameters. During testing, motor 51 is started, and its output drives synchronous belt 52. Synchronous belt 52 drives multiple driven pulleys 53 to rotate, which in turn drives roller 44 to rotate synchronously. At this time, the rubber sleeve 46 on the surface of roller 44 contacts the steel rope 6. The anti-slip strip 47 on the rubber sleeve 46 increases friction to ensure that the steel rope 6 moves synchronously and uniformly with the roller 44. Two sets of clamping pulleys 54 on the surface of support frame 41, close to synchronous belt 52, limit and tension synchronous belt 52 to prevent slippage or deviation and ensure transmission stability. Finally, the steel rope 6 is tested. Two rollers 44 clamp the steel rope 6 from the top and bottom to prevent the steel rope 6 from swaying due to its own weight or external force when moving. Detector 3 is fixedly located directly above support frame 41. The positioning of steel rope 6 by roller 44 ensures that it is always aligned with the detection area of ​​steel rope 6. The detection data of steel rope 6 is acquired in real time and transmitted to detector 1 through data cable 2 to complete the automated detection of steel rope 6. The detector 1 is placed on top of the top block 74 on the side wall of the support frame 41. The top block 74 is directly below the detector 1, supporting it from the bottom and providing vertical support. The auxiliary threaded posts 72 on the inner walls of the clamping blocks 71 on both sides of the support frame 41 are rotated according to the width of the detector 1. The auxiliary threaded posts 72 are threadedly connected to the inner walls of the clamping blocks 71. The fixing blocks 73 on both sides gradually approach and fit onto the surface of the detector 1, forming a clamping force from both sides to limit the horizontal swaying of the detector 1. The bottom support of the top block 74 and the clamping force of the fixing blocks 73 work together to stably fix the detector 1 on the support frame 41, preventing the equipment from shifting due to vibration or external force during testing. When the device installation preparation is carried out, the sleeve ring 81 is inserted into the receiving groove 84 of the support frame 41, then the sleeve ring 81 and the support frame 41 are fixed by the mounting pin 83, the cleaning device 8 is ensured to be stable, then the steel rope 6 to be detected is sequentially threaded through the brush 82 in the sleeve ring 81 and the sponge pad 86 in the connecting ring 85, so that both of them are sleeved on the surface of the steel rope 6 to prepare for cleaning. When the steel rope 6 is uniformly moved under the driving of the driving assembly 5, the cleaning operation is carried out, the brush 82 in the sleeve ring 81 first contacts the surface of the steel rope 6 to brush off the dust, oil stains, rust and other larger particle impurities attached on the surface of the steel rope 6, the sponge pad 86 in the connecting ring 85 on the side wall of the sleeve ring 81 is closely attached to the steel rope 6 to further wipe the remaining small impurities or oil stains, forming a double cleaning effect of first brushing and then wiping, and improving the surface cleanliness of the steel rope 6. The received and maintained cleaning after detection is completed or not needed, the sleeve ring 81 is taken off from the fixing frame by unscrewing the mounting pin 83, so that the device is avoided from being exposed and damaged and space is saved, and when the brush 82 or the sponge pad 86 is worn, the sleeve ring 81 can be replaced by dismounting the mounting pin 83, so that the maintenance can be completed to guarantee the subsequent cleaning effect.
