The oil brush gun 22 and the detection gun 21 are arranged at parallel intervals on the jig 1. The tong openings of the gripping tong 21 and the oil brush tong 22 together form a gripping channel 23, through which the steel cable 100 runs.By providing the camera 3 on the detection tong 21, when the wire rope 100 passes through the detection channel 23, the camera 3 can capture an image of the wire rope 100. As the wire cable 100 moves in the detection channel 23 from beginning to end, the camera 3 captures a series of images. These images may be processed to synthesize an image of the entire length of the wire rope 100. By analyzing the images, relevant surface data of the wire rope 100 can be obtained, which after working the wire rope 100 for a period of time can be compared and analyzed by the acquisition with the surface data returned by the original image of the wire rope 100 to obtain the broken wire development of the entire length of the wire rope, the fatigue failure properties of steel ropes 100 including the total number of broken wires in each steel rope, thereby providing direct data support for determining whether the steel rope 100 meets the scrap standard.In related technologies, the cleaning solution for wire rope inspection is to submerge the wire rope to be detected in a solvent of the dirt receiving tank to dissolve the oil on the surface of the wire rope.

At this time, the tong openings of the oil brush tong 22 and the grasping tong 21 are both in an open state. The heights of the tong openings of the sensing tong 21 and the oil brush tong 22 can be adjusted by adjusting extension and retraction of the vertical support rod 103 to match the height of the wire rope 100 to be inspected. By sliding the jig 1 along the slide guide mechanism 5, the positions of the detection tong 21 and the oil brush tong 22 relative to the wire rope 100 to be inspected can also be adjusted by rotating disk 4002, ball joint 1033, and other methods so that the full length of the wire rope 100 is detected from beginning to end. By the control of the pitch drive mechanism 4, the pitch drive motor 401 electrically rotates the drive gear 402, the drive gear 402 drives the driven gear 403 to rotate, thereby driving the vertical support rod 103 to rotate to adjust the tong openings of the inspection tong 21 and the oil brush tong 22 to be coaxial with the wire rope 100 to be detected. When the wire rope 100 has been moved into the detection channel 23, the second electromagnet 6 is energized and closed, whereby all the tong openings close and the device is in a ready state. At this time, the wire rope 100 may be in motion.Upon starting the detection, the wire rope 100 moves, the camera 3 continues to capture, the detection tong 21 continues to capture until all the wires 100 pass through the openings of the detection tongs 21 and return to the origin.The images of each identical portion taken by a plurality of cameras 3 are transmitted wirelessly or wired to the industrial computer 8, the control unit then processes the images to provide direct image data for the subsequent analysis of fatigue damage of the steel cord. The control unit performs the above steps of the wire rope inspection method to determine whether the steel rope 100 meets the scrap standard.The present invention has high working efficiency. In performing the detection of wire rope 100, only the entire wire rope 100 needs to pass through the detection channel 23. The camera 3 on the detection tong 21 scans all portions of the wire rope 100 once to complete the detection.The control system can not only record, inspect, and analyze surface defects of the wire rope 100 by the camera 3, but also accurately measure the rope diameter and the twisting distance, etc. It can also electromagnetically inspect the internal wire breakage of the wire rope 100 by various detection methods such as strong and weak.

During the external wire breakage inspection of the wire rope 100, the internal wire breakage can be detected by the strong and weak magnetic inspection probe 70 by the magnetic detection method. After the sensing data is transmitted to the analysis and control system, an image deconvolution diagram may also be formed to record the data within the wire rope. Comprehensive analysis is performed by using the built-in control system hardware and the high performance analysis, computation and research and discovery software of the system. Since the control system synchronously receives information from the high-precision encoder of the traveling mechanism of the wire rope 100, the specific position of the failure point of the wire rope 100 is accurately positioned to perform comprehensive comparative analysis of the same point at different timings.The force and damage mechanism of wire rope 100 is very complex. Even if the same type of wire rope 100 is used on similar equipment, the final scrap location and damage shape of wire rope 100 are not the same. Therefore, the method of using the wire rope inspection apparatus provided in this embodiment is as follows. Initial detection is performed with the wire rope inspection apparatus after re-installing the wire rope 100, and the basic data of the new wire rope 100 is recorded under tension and without tension, mainly including the diameter, the twisting distance, and the initial surface defects (if any) of the wire rope 100 under tension and without tension. After the steel cord 100 is used for a certain period of time, the state of the steel cord 100 is regularly detected with the steel cord inspection device. The system summarizes the inspection results with previous historical data such as cable diameter and twist pitch at the same issue point, compares and analyzes the same location, and systematically analyzes the associated adjacent location data to determine if it meets the scrap standard. Point-to-point comparison is made via the development of errors in key error locations, as well as systematic research and prediction of development trends to accurately emphasize the hidden hazard points of the steel cord 100 and facilitate key examinations. Many inspection operations are performed throughout the life cycle of wire rope 100. The present invention transmits real-time inspection data of the inner and outer parts of wire rope 100 to the control system, and the built-in program of the control system will record, summarize, and sum comprehensive analyses according to the time axis. The trend of the development of damage to the wire rope 100 is comprehensively analyzed and predicted, provisional analysis opinions are proposed for the causes of abnormal situations, so that management personnel can further analyze and correct them by comparing them.As the sensing data accumulates, the built-in program of the control system can deeply analyze the acquired data information, such as the determination of broken wire development within the 6D and 30D ranges, the total number of broken wires in each steel wire, the corresponding analysis of the concentrated and frequently used location of broken wires, and an analysis diagram is automatically formed to analyze the causes of scrapping and damage to wire rope 100, and provide direct data support to determine whether wire rope 100 meets scrapping standards. Even based on the initial twisting distance and the rope diameter, if the rope diameter and the twisting distance change to some extent, it can be determined that there are defects such as broken strands in the rope, and this requires scrapping and replacement. The present invention not only inspects the surface of the wire rope, but also detects the inner state of the wire rope by methods such as strong or weak magnetic detection. If the broken wire inside the wire rope exceeds the standard, it is more dangerous than the damage on the surface of the wire rope due to inconveniences in the inspection, it is also more necessary.The present invention has the following advantages:(1) High detection accuracy. Innovative point-to-point comparison analyses pre-copes with the development of defects in key defect locations of wire rope and ensures that all positions within the entire rope length range of the steel rope are monitored.(2) High degree of automation. By collaborative action of various devices and locations, automation from precise positioning of the steel cord during the acquisition preparation phase to oil removal, performing acquisition, data acquisition, and analysis in the acquisition process can be achieved to ensure the working quality of the acquisition.(3) High safety. Once the device has started up, the employees only need to monitor the sensing data remotely in real time in order to improve the health protection of the employees.(4) Strong universality. For various types of equipment using wire ropes, this apparatus can be used for wire rope detection and wire rope detection whether it meets the scrap standard.(5) High working efficiency. When performing the detection of wire rope, only the entire wire rope needs to pass through the detection channel. The camera on the capturing device scans all portions of the wire rope once to complete the capturing. The working efficiency is high.(6) The system has a simple structure, simple and compact construction, compact size, strong fit capability to the work platform and low system cost.(7) It can achieve internal nondestructive detection and reliable and systematic analysis of various operating modes of wire ropes and has good market application prospects.Although embodiments of the present invention will be described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, all of which fall within the scope defined by the appended claims.
