Description

Technical Field

[0001] This invention belongs to the field of testing equipment technology, and specifically relates to a non-destructive testing device and testing system for steel wire ropes. Background Technology

[0002] As a core load-bearing component in hoisting, transportation, and mining industries, the operating condition of wire ropes directly affects equipment safety and production efficiency. During long-term service, wire ropes are prone to reduced load-bearing capacity due to defects such as wear, corrosion, bending, and breakage, which can lead to safety accidents. Therefore, accurate non-destructive testing of wire ropes is crucial.

[0003] Existing non-destructive testing technologies for wire ropes mainly include magnetic particle testing, ultrasonic testing, and contact testing. Among these, contact testing devices are widely used in small- to medium-scale scenarios due to their simple structure and low cost. However, existing contact testing devices have several shortcomings: First, wire ropes are often used in complex outdoor environments, and their surfaces are easily covered with dirt, sand, and other debris. Existing devices lack efficient cleaning mechanisms, and this debris can easily cause wear on the testing contacts or distortion of the detection signal, severely affecting the testing accuracy. Second, the contact positions of existing testing mechanisms are mostly fixed, making it difficult to adapt to wire ropes of different diameters. Furthermore, the contact detection range is limited, failing to fully cover the circumference of the wire rope and easily missing local defects. Third, some testing devices can only achieve unidirectional detection movement, resulting in poor adaptability to wire ropes of different lengths. Testing short sections of wire rope is cumbersome and inefficient. To address these problems, this invention provides a non-destructive testing device and system for wire ropes. Summary of the Invention

[0004] To address the aforementioned technical problems, the technical solution adopted by this invention is: a non-destructive testing device for steel wire ropes, the testing device comprising: The housing has an inlet and an outlet at each end, which allow the wire rope to pass through. The testing mechanism is located inside the housing and includes multiple contact heads. When testing a steel wire rope that has entered the housing, the contact heads contact the steel wire rope and perform the testing. A cleaning mechanism is installed on the housing near the feed inlet. The cleaning mechanism is used to clean impurities from the surface of the wire rope to improve the detection accuracy of the contact head.

[0005] Furthermore, the detection mechanism also includes an internal turntable, on which multiple guide rods are fixedly installed. Connecting blocks are slidably installed on the guide rods. A return spring is provided between the connecting block and the rectangular groove on the turntable. A measuring rod is fixedly installed on the connecting block and is fixedly connected to the contact head.

[0006] Furthermore, the detection mechanism also includes a movable plate slidably installed inside the housing. The movable plate rotates in coordination with the turntable. The movable plate is fixedly connected to the extended end of a cylinder. The cylinder is fixedly installed on the housing. By extending or retracting the extended end of the cylinder, the position of the movable plate and the turntable installed on the movable plate is controlled, thereby adjusting the horizontal position of multiple contact heads.

[0007] Furthermore, the detection mechanism also includes a first motor, which is fixedly mounted on a movable plate. The output shaft of the first motor passes through the movable plate and is fixedly connected to a first gear. The first gear meshes with a second gear, and the second gear is fixedly connected to a turntable. The first gear and the second gear are rotatably mounted on the movable plate. The first motor drives the first gear and the second gear to rotate, so that the turntable rotates relative to the movable plate, thereby expanding the detection range of the contact head on the surface of the wire rope.

[0008] Furthermore, the testing mechanism also includes multiple cameras mounted on a turntable, and each camera has an active learning mode.

[0009] Furthermore, multiple guide grooves are provided along the length of the shell, and multiple guide blocks are provided on the movable plate. The guide grooves and guide blocks correspond one-to-one, and the guide blocks and guide grooves are slidably engaged.

[0010] Furthermore, two symmetrically arranged first feeding rollers are provided on both sides of the feed inlet and the discharge outlet. The first feeding rollers are connected to the housing through connecting arms and are used to drive the steel wire rope to move.

[0011] Furthermore, the cleaning mechanism includes a scraper, which is slidably engaged with a horizontal column fixedly mounted on the housing. The scraper is rotatably connected to one end of a side arm on each side, and the other end of the side arm is rotatably connected to a lifting rod. The lifting rod is slidably engaged with a rectangular groove on a lifting frame. The lifting frame is slidably mounted on the outside of the housing and is fixedly connected to a boss on a drive disc. The drive disc is fixedly connected to the output shaft of a second motor, and the second motor is fixedly mounted on the outside of the housing.

[0012] Furthermore, the cleaning mechanism also includes a collection trough, which is fixedly connected to the scraper and is used to collect debris cleaned off the wire rope by the scraper.

[0013] On the other hand, the present invention provides a non-destructive testing system for steel wire ropes, comprising: A cleaning box, which is used to clean the surface of the steel wire rope to be tested; A lubrication box, used to apply lubricating oil to the steel wire rope after testing; and the aforementioned testing device.

[0014] The advantages of this invention compared to the prior art are: (1) The testing mechanism adopts a structure of motor-driven gear set and turntable, which can drive the contact head to rotate around the steel wire rope. Combined with the horizontal movement of the cylinder-driven moving plate, it can achieve full coverage of the testing range, effectively avoid missing local defects, expand the testing range and improve the testing accuracy. (2) The cleaning mechanism drives the drive plate, lifting frame and side arm through the motor to drive the scraper to slide back and forth in the horizontal direction, and works with the collection trough to achieve efficient cleaning and collection of debris; (3) By setting up a cylinder and a turntable, the present invention can meet the detection requirements in both the moving and non-moving states of the wire rope, and is highly practical. (4) By setting up both a contact head and a camera in the testing facility, and using the contact head as a reference testing unit to calibrate and verify the recognition results of the camera, the camera can gradually build up defect feature samples and optimize its recognition capabilities during use, thereby achieving collaborative work between contact testing and visual testing. This ensures testing reliability, improves testing efficiency, and reduces long-term wear of the contact head. Attached Figure Description

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0029] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0030] Example: Figures 1-12 The device shown is a non-destructive testing device for steel wire ropes. The testing device includes: The housing 1 has an inlet and an outlet at both ends that allow the wire rope to pass through. The testing mechanism is located inside the housing 1 and includes multiple contact heads 13. When the wire rope that has entered the housing 1 is tested, the contact heads 13 contact the wire rope and perform the test. The cleaning mechanism is installed on the housing 1 at one end near the feed inlet. The cleaning mechanism is used to clean the impurities on the surface of the wire rope to improve the detection accuracy of the contact head 13.

[0031] During the inspection of the wire rope, if the inspection device does not move while the wire rope moves continuously, the wire rope enters from the feed port at one end of the housing 1, passes through the inspection mechanism located inside the housing 1, and is inspected by the contact head 13. After inspection, the wire rope is discharged through the discharge port at the other end of the housing 1. If the inspection is to be carried out on a shorter section of wire rope, the wire rope is fixed at the feed port and discharge port, and the housing 1 is pushed to move to complete the inspection of the wire rope.

[0032] Since the wire rope is outdoors, it is unavoidable that clumps of mud, sand and gravel will remain on the surface of the wire rope, which will affect the testing structure. Therefore, it is necessary to clean it through a cleaning mechanism. The cleaning mechanism is set in front of the feed inlet. The wire rope to be tested first passes through the cleaning mechanism, which scrapes off the debris adhering to the surface of the wire rope before it enters the feed inlet.

[0033] The testing mechanism also includes a turntable 8 inside, on which multiple guide rods 9 are fixedly installed. A connecting block 11 is slidably installed on the guide rods 9. A return spring 10 is provided between the connecting block 11 and the rectangular groove on the turntable 8. A measuring rod 12 is fixedly installed on the connecting block 11 and is fixedly connected to the contact head 13.

[0034] like Figure 5 , Figure 6 As shown, the turntable 8 has a hole at its center that allows the wire rope to pass through. When the wire rope passes through the hole at the center of the turntable 8, multiple contact heads 13 will contact the surface of the wire rope. Initially, the multiple contact heads 13 are arranged in a circle. When inspecting the wire rope, the end of the wire rope is manually straightened. The straightened end passes through the multiple circumferentially arranged contact heads 13, and the multiple contact heads 13 are pushed away from the center of the turntable 8. Since the wire rope is straightened, the contact heads 13 move the same distance. The state of the contact heads 13 after moving the same distance is defined as the initial state. Then, the wire rope is continuously fed into the housing 1 for inspection. The state of the contact heads 13 is used to determine whether there are defects on the surface of the wire rope and the type of defects. The specific details are as follows: Scenario 1: If none of the contact heads 13 are displaced when the wire rope continuously passes through them, it means that the distance that all the contact heads 13 on the surface of the wire rope moves relative to the center of the turntable 8 is the same. This means that the surface of the wire rope to be tested is intact, without wear, bending, or breakage.

[0035] Scenario 2: For example Figure 9 As shown, if, while the wire rope continues to pass the contact head 13, the contact head 13 on one side continues to be pushed by the wire rope and moves further away from the center of the turntable 8, while the contact head 13 on the opposite side moves closer to the center of the turntable 8, then it indicates that the surface of the wire rope is bent. When the wire rope is bent, its surface forms an asymmetrical arc-shaped structure. The contact head 13 on the outer side of the arc is continuously supported by the wire rope and undergoes a large displacement, while the contact head 13 on the inner side of the arc, due to weakened contact, moves towards the center of the turntable 8 under the elastic force of the return spring 10.

[0036] Scenario 3: For example Figure 11 As shown, if, while the wire rope is continuously passing the contact head 13, one of the contact heads 13 moves closer to the center of the turntable 8, while the other contact heads 13 do not move, especially the contact head 13 corresponding to the moving contact head 13 does not move, this indicates that the surface of the wire rope has been worn or broken. Since the wire rope is formed by winding multiple strands of wire, and each strand of wire is composed of multiple single wires, if the wire rope is worn, it means that one or more single wires in a strand are worn, while the whole strand is still connected. In this case, the distance that the contact head 13 moves will be less than the diameter of a single strand of wire. like Figure 10 As shown, if every single wire in a single strand of steel wire breaks, it means that the entire strand of steel wire has broken. At this time, the distance that the contact head 13 moves will be equal to the diameter of the single strand of steel wire.

[0037] It should be noted that in existing technology, a common steel wire rope is made of multiple strands of steel wire of the same diameter twisted together, and each strand of steel wire is formed by combining multiple single-strand steel wires. To facilitate understanding scenario three, as... Figure 10 and Figure 11 As shown, the wire rope is made of multiple identical strands of G wound together (two strands are shown in the attached diagram, which is a cross-sectional view of the wire rope). Each strand of G is composed of multiple g1, g2, g3, etc., of the same material and size. In this embodiment, g1, g2, and g3 are used as an example to form G. If wear occurs in the wire rope, it means that at least one of the g1, g2, or g3 in G has broken; if the wire rope breaks, it means that at least one G that makes up the wire rope has broken as a whole.

[0038] The testing mechanism also includes a movable plate 3 that is slidably installed inside the housing 1. The movable plate 3 is rotatably engaged with the turntable 8. The movable plate 3 is fixedly connected to the extended end of the cylinder 14. The cylinder 14 is fixedly installed on the housing 1. By extending or retracting the extended end of the cylinder 14, the position of the movable plate 3 and the turntable 8 installed on the movable plate 3 is controlled to adjust the horizontal position of the multiple contact heads 13.

[0039] like Figure 1 , Figure 3 , Figure 4 As shown, during the inspection of the wire rope, the wire rope can remain stationary while the inspection mechanism moves. Specifically, the cylinder 14 is activated, causing its extended end to move the moving plate 3 inside the housing 1. The turntable 8 is rotatably connected to the moving plate 3, so the turntable 8 and its multiple contact heads 13 move with the moving plate 3 inside the housing 1, thereby enabling the contact heads 13 to complete the inspection of the wire rope.

[0040] The testing mechanism also includes a first motor 5, which is fixedly mounted on the movable plate 3. The output shaft of the first motor 5 passes through the movable plate 3 and is fixedly connected to the first gear 6. The first gear 6 meshes with the second gear 7, and the second gear 7 is fixedly connected to the turntable 8. The first gear 6 and the second gear 7 are rotatably mounted on the movable plate 3. The first motor 5 drives the first gear 6 and the second gear 7 to rotate, so that the turntable 8 rotates relative to the movable plate 3, thereby expanding the detection range of the contact head 13 on the surface of the wire rope.

[0041] like Figure 4 As shown, during the inspection process using contact heads 13, to improve inspection accuracy, all surfaces of the wire rope are inspected. Alternatively, to verify the inspection results, multiple contact heads 13 can rotate around the central axis of the turntable 8, changing the contact position of each contact head 13 with the wire rope. Specifically, the first motor 5, fixedly mounted on the turntable 8, is activated, causing the first motor 5 to drive the first gear 6 to rotate. The second gear 7 meshes with the first gear 6, thus rotating the second gear 7 and driving the turntable 8, which is fixedly connected to the second gear 7, to rotate. This causes the multiple contact heads 13 on the turntable 8 to rotate, completing the position adjustment.

[0042] The testing facility also includes multiple cameras mounted on turntable 8, which have an active learning mode.

[0043] In this preferred embodiment, multiple cameras can be installed on the turntable 8 to capture images of the surface of the wire rope and complete the inspection. On the one hand, the inspection results from the cameras can be cross-verified with the inspection results from the contact head 13, improving the accuracy of the inspection; on the other hand, if either the camera or the contact head 13 is damaged, the other can still be used for inspection without affecting the efficiency of the inspection.

[0044] In this embodiment, the simultaneous use of the contact head 13 and the camera is not merely a simple redundancy, but rather a means to construct a collaborative detection and adaptive optimization mechanism. The camera is preferably an intelligent camera with local data processing capabilities, capable of active learning. During the detection process, it continuously acquires images of the wire rope surface and compares the acquired image features with the detection results output by the contact head 13. In the initial stage of device use, the contact head 13 serves as a highly reliable benchmark detection unit, and its detection results are used to calibrate and correct the camera's recognition judgment. As the number of detections increases, the camera gradually forms a defect feature sample library based on historical detection data and continuously optimizes its ability to identify the surface condition of the wire rope. During this process, the camera's accuracy in identifying defects such as bending, wear, and breakage gradually improves, allowing for greater reliance on the camera for rapid identification in subsequent detections. The contact head 13 is then used for periodic verification and accuracy correction. Through this approach, collaborative work and performance evolution of contact detection and visual detection are achieved, ensuring detection reliability while improving detection efficiency and extending the service life of the contact head 13.

[0045] Multiple guide grooves 2 are provided along the length of the housing 1, and multiple guide blocks 4 are provided on the movable plate 3. The guide grooves 2 and guide blocks 4 correspond one-to-one, and the guide blocks 4 and guide grooves 2 slide together.

[0046] like Figure 4 , Figure 8 As shown, in this embodiment, in order to enable the movable plate 3 to move smoothly inside the housing 1, multiple guide blocks 4 are provided on the movable plate 3, and multiple guide grooves 2 are provided on the housing 1, with the guide grooves 2 and guide blocks 4 installed in a one-to-one correspondence. When the extended end of the cylinder 14 drives the movable plate 3 to move, the guide blocks 4 will slide smoothly along the guide grooves 2.

[0047] Two symmetrically arranged first feeding rollers 15 are provided on both sides of the inlet and outlet. The first feeding rollers 15 are connected to the housing 1 through the connecting arm 16. The first feeding rollers 15 are used to drive the wire rope to move.

[0048] like Figure 1 , Figure 2 As shown, a first feeding roller 15 is provided at both the inlet and outlet. The first feeding roller 15 is rotatably connected to the connecting arm 16. The two first feeding rollers 15 are used to convey the wire rope and improve the stability of the wire rope movement.

[0049] The cleaning mechanism includes a scraper 17, which is slidably engaged with a horizontal column 18 fixedly mounted on the housing 1. The two sides of the scraper 17 are rotatably connected to one end of a side arm 19, and the other end of the side arm 19 is rotatably connected to a lifting rod 21. The lifting rod 21 is slidably engaged with a rectangular groove 23 on a lifting frame 22. The lifting frame 22 is slidably mounted on the outside of the housing 1 and is fixedly connected to a boss on a drive disc 24. The drive disc 24 is fixedly connected to the output shaft of a second motor 25, which is fixedly mounted on the outside of the housing 1.

[0050] The cleaning mechanism also includes a collection trough 20, which is fixedly connected to the scraper 17. The collection trough 20 is used to collect the debris that the scraper 17 cleans off from the wire rope.

[0051] like Figure 1 , Figure 7 As shown, the surface of the wire rope needs to be cleaned before it enters the feed inlet. Specifically, the second motor 25 is started, and the output shaft of the second motor 25 drives the drive disk 24 to rotate. At this time, the boss on the drive disk 24 will slide relative to the rectangular groove 23 during the rotation. Then, the lifting frame 22 will slide back and forth vertically along the outside of the housing 1, thereby driving the lifting rod 21 to move up and down back and forth.

[0052] As the lifting rod 21 moves, it pushes the side arm 19 to drive the scraper 17 to slide horizontally along the horizontal column 18. The scraper 17 contacts the surface of the wire rope, thereby scraping off the debris adhering to the surface of the wire rope. The scraped debris falls into the collection trough 20 for collection.

[0053] The present invention also provides a non-destructive testing system for steel wire ropes, comprising: Cleaning box 26 is used to clean the surface of the wire rope to be tested; Lubrication box 27, used to apply lubricating oil to the steel wire rope after testing; and the aforementioned testing device.

[0054] like Figures 1-12 As shown, the testing system includes a cleaning box 26 and a lubrication box 27. When a large number of continuous steel wire ropes need to be tested in the workshop, the steel wire ropes are first cleaned in the cleaning box 26. To improve cleaning efficiency, multiple rotating rollers can be added to the cleaning box 26 to remove surface dust from the steel wire ropes. The cleaned steel wire ropes are then guided by the second feeding roller 30 into the testing device for testing (the testing principle is the same as described above and will not be repeated here).

[0055] After the inspection is completed, the wire rope is initially straightened by the support plate 32 and the support roller 31. After the initial straightening, the wire rope will pass through the lubrication box 27, which contains lubricating oil. By applying lubricating oil to the surface of the wire rope, rust can be prevented.

[0056] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
