Description

Technical Field

[0001] This utility model belongs to the field of magnetic flux leakage detection technology, and more specifically, relates to magnetic flux leakage detection equipment suitable for detecting multiple rows of parallel and synchronously operating wire ropes. Background Technology

[0002] In modern industrial production and transportation, wire ropes, as important mechanical transmission and load-bearing components, are widely used in various equipment and systems, such as cranes, elevators, mine hoists, port loading and unloading equipment, and cable cars. The performance and reliability of wire ropes directly affect the safe operation and production efficiency of equipment. However, during long-term use, wire ropes are affected by various factors, leading to defects such as wear, broken wires, deformation, and corrosion. If these defects are not detected and addressed in a timely manner, they may cause serious safety accidents, resulting in huge economic losses and casualties. Therefore, regular and accurate inspection of wire ropes is particularly important.

[0003] Traditional wire rope inspection methods primarily rely on manual visual inspection and manual measuring tools. Manual visual inspection mainly involves inspectors visually observing the surface of the wire rope for wear, broken wires, etc., but this method has obvious limitations. First, manual inspection is highly subjective; different inspectors have varying experience and judgment standards, easily leading to inconsistent test results. Second, manual inspection can only observe obvious surface defects, making it difficult to detect internal defects, minute defects, and defects in hidden areas. Furthermore, manual inspection is inefficient and unsuitable for inspecting wire ropes over long distances in complex environments.

[0004] With the development of technology, some physical principle-based testing technologies have been gradually applied to the field of wire rope inspection, such as magnetic particle testing, ultrasonic testing, and eddy current testing. Magnetic particle testing utilizes the leakage magnetic field at defects on the surface of the wire rope to attract magnetic powder, thereby revealing the shape and location of the defects. However, magnetic particle testing requires coating the wire rope surface with magnetic powder, making the process cumbersome, requiring high environmental conditions, susceptible to external interference, and resulting in low testing efficiency. Ultrasonic testing detects defects by detecting the reflection, refraction, and scattering phenomena caused by ultrasonic waves encountering defects as they propagate within the wire rope. However, ultrasonic testing requires high operator skills, and interpreting ultrasonic signals can be difficult for complex defect morphologies and structures. Eddy current testing utilizes the principle of electromagnetic induction, detecting changes in eddy currents to determine the condition of the wire rope. While eddy current testing offers a certain advantage in detection speed, its ability to detect deep defects in wire ropes is limited, and it is easily affected by the surface condition of the wire rope and environmental factors.

[0005] Multi-row parallel synchronous operating wire ropes are a special mechanical system that achieves load balance through the synchronous traction of multiple rows of wire ropes, commonly found in scenarios such as double-hook electric hoists and mine transportation. The operating characteristics of this type of wire rope place higher demands on testing equipment. Currently, intelligent testing equipment for multi-row parallel synchronous operating wire ropes typically increases the number of testing devices, using a quantitative accumulation approach to meet intelligent testing functions. This method of accumulating testing equipment has several problems. First, the equipment utilization rate is low; a large number of testing devices cannot fully utilize their functions in actual use, leading to resource waste. Second, the simultaneous operation of multiple testing devices consumes a large amount of energy, resulting in high energy consumption and increased testing costs. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Reference Figures 1-5 A magnetic flux leakage detection device suitable for detecting multiple rows of parallel and synchronously operating wire ropes, comprising a frame 1, a mobile platform 2, and multiple magnetic flux leakage detection units.

[0023] The mobile platform 2 is mounted on the frame 1. The mobile platform 2 includes a first power mechanism 21 and a mobile base 22. The first power mechanism 21 is connected to the mobile base 22 to drive the mobile base 22 to move linearly to approach and move away from the wire rope.

[0024] Each of the magnetic flux leakage detection units includes a tilt adjustment mechanism 3, a detection probe 4, a coding device 5, and an encoder assembly. The detection probe 4 is hinged to the movable base 22 via a first hinge shaft 401 for magnetizing and detecting magnetic flux leakage of the wire rope entering the detection probe 4. The tilt adjustment mechanism 3 is hinged to the detection probe 4 via a second hinge shaft 402 and to the movable base 22 via a third hinge shaft 24 for adjusting the tilt angle of the detection probe 4. The first hinge shaft 401, the second hinge shaft 402, and the third hinge shaft 24 are parallel to each other and are arranged in a triangle. The coding device 5 is mounted on the movable base 22 for marking defective parts of the wire rope. The encoder assembly is mounted on the movable base 22 for fitting the wire rope.

[0025] The detection probe 4 saturates the wire rope with magnetization. When the magnetic lines of force encounter cross-sectional losses or localized damage in ferromagnetic materials, they overflow onto the surface, creating a leakage magnetic field. This means that the system can not only detect surface wear and corrosion, but also effectively detect fractures in the core rope inside the wire rope.

[0026] In actual working conditions, steel wire ropes are often not vertical or horizontal, but have a specific angle of inclination, which may vary with the load. This invention introduces an angle adjustment mechanism 3, which hinges the detection probe 4 via a second hinge shaft 402 and the moving seat 22 via a third hinge shaft 24. This double-hinged linkage design creates a highly flexible attitude adjustment system. It can flexibly adjust the pitch angle of the detection probe 4 according to the actual spatial angle of the steel wire rope under test, achieving parallel and flexible docking between the detection probe 4 and the steel wire rope. This attitude matching is crucial. If there is an angle between the detection probe 4 and the steel wire rope, it will cause drastic fluctuations in the lift-off value between the magnetic sensing element inside the probe and the surface of the steel wire rope, generating huge noise signals, and even causing jamming or probe damage. By keeping the attitude of the detection probe 4 consistent with that of the steel wire rope, the stability of the detection and the high signal-to-noise ratio of the signal are ensured.

[0027] The inkjet marking device 5 marks the defective areas of the wire rope detected by the detection probe 4. When the detection probe 4 detects a defect in the wire rope, the central control platform immediately calculates the location of the defect and triggers inkjet printing the instant the defect passes the inkjet marking device 5 (the relative position of the inkjet marking device 5 and the detection probe 4 is known, therefore the position of the inkjet marking device 5 and the detected defect is known). This function instantly converts the digital defect into a physical mark. For later maintenance, simply locate the location marked by the inkjet marking device 5 to perform the operation.

[0028] Furthermore, the first power mechanism 21 is an electric push rod, and rollers 23 are mounted on the movable seat 22, with the frame 1 supporting the rollers 23. Using an electric push rod as the first power mechanism 21 enables precise linear movement control of the movable seat 22. The electric push rod has high stroke accuracy and stability, ensuring the movement accuracy of the movable seat 22 when approaching or moving away from the wire rope. The rolling friction of the rollers 23 is much less than the sliding friction, thereby reducing energy loss and improving the system's movement efficiency. Simultaneously, the rolling motion of the rollers 23 ensures the smooth movement of the movable seat 22, avoiding vibration or shaking caused by excessive friction, thus improving the stability of the detection probe 4 during operation.

[0029] Furthermore, the tilt adjustment mechanism 3 can adopt a conventional electric push rod to achieve automatic tilt adjustment; preferably, the tilt adjustment mechanism 3 includes a first connecting rod 31, a threaded sleeve 33, and a second connecting rod 32. The first end of the first connecting rod 31 is provided with a first external thread, and the first end of the threaded sleeve 33 is provided with a first internal thread that mates with the first external thread. The first connecting rod 31 is threadedly connected to the first end of the threaded sleeve 33. The first end of the second connecting rod 32 is provided with a second external thread, the second external thread having the opposite rotation direction to the first external thread. The second end of the threaded sleeve 33 is provided with a second internal thread that mates with the second external thread, and the second connecting rod 32 is threadedly connected to the second end of the threaded sleeve 33.

[0030] The second end of the first connecting rod 31 is hinged to the detection probe 4 via the second hinge shaft 402, and the second end of the second connecting rod 32 is hinged to the movable seat 22 via the third hinge shaft 24.

[0031] By turning the threaded sleeve 33, the relative distance between the first connecting rod 31 and the second connecting rod 32, as well as the tilt angle of the first connecting rod 31 and the second connecting rod 32, can be adjusted, thereby allowing the first connecting rod 31 to drive the detection probe 4 to rotate around the center line of the first hinge shaft 401.

[0032] The tilt adjustment mechanism 3, through the combination of the first connecting rod 31, the threaded sleeve 33, and the second connecting rod 32, enables precise adjustment of the tilt angle of the detection probe 4. This design allows the detection probe 4 to maintain optimal contact with the wire rope at different tilt angles, thereby ensuring the accuracy and reliability of the detection. Especially in applications with multiple rows of parallel and synchronously operating wire ropes, the tilt angle of the wire rope may change due to the operating conditions of the equipment. The tilt adjustment mechanism 3 can quickly adapt to these changes, ensuring that the detection probe is always in the optimal detection position.

[0033] Furthermore, the detection probe 4 includes a probe bracket 41, a second power mechanism 42, a magnetizer, a magnetic sensitive element, and a wear-resistant element. The probe bracket 41 is mounted on the movable base 22. The magnetizer has a split structure and includes a first magnet 431 and a second magnet 432. The first magnet 431 is mounted on the probe bracket 41, and the second power mechanism 42 is mounted on the probe bracket 41. The second power mechanism 42 is connected to the second magnet 432 and is used to drive the second magnet 432 to move, thereby allowing the second magnet 432 and the first magnet 431 to move closer and further apart to accommodate steel wire ropes of different diameters. The magnetic sensitive element is mounted on the probe bracket 41 and extends into the magnetizer to detect the leakage magnetic field outside the steel wire rope. The wear-resistant element is mounted on the magnetizer and located between the magnetic sensitive element and the steel wire rope to protect the magnetic sensitive element.

[0034] The first magnet 431 and the second magnet 432 can move closer to or further away from each other. This design allows the detection probe 4 to adapt to steel wire ropes of different diameters without requiring replacement or complex adjustments. Furthermore, when they are far apart, they form an opening, facilitating the entry of the steel wire rope into the detection probe 4. The magnetic sensing element enables high-precision detection of internal and surface defects in the steel wire rope. Wear-resistant elements prevent direct contact between the first magnet 431 and the second magnet 432 and the steel wire rope. This design not only protects the magnetizer from wear on the steel wire rope surface but also reduces performance degradation caused by long-term friction.

[0035] Furthermore, the probe bracket 41 is mounted on the movable seat 22 via two parallel guide shafts A44, and a sliding bearing 45 is respectively provided between the probe bracket 41 and each guide shaft A44. The guide shafts A44 are perpendicular to the output shaft of the second power mechanism 42. Unevenness (such as strands) on the surface of the wire rope or slight changes in diameter can generate high-frequency impact forces on the probe. The sliding bearings 45 provide a contact interface with a low coefficient of friction, allowing the probe bracket 41 to slide sensitively on the guide shafts A44. This means that when the position of the wire rope shifts slightly, the detection probe can smoothly follow the movement instead of getting stuck due to excessive static friction, preventing hard collisions or excessive compression between the probe and the wire rope.

[0036] Furthermore, an elastic buffer mechanism 46 is provided between the probe bracket 41 and the movable seat 22 to buffer the axial movement of the probe bracket 41 along the guide shaft A44.

[0037] During high-speed operation, wire ropes often experience severe lateral vibration, whipping effects, and periodic vibrations caused by their own twisting. The elastic buffer mechanism 46, through elastic deformation, converts instantaneous impact kinetic energy into elastic potential energy or dissipates heat, significantly mitigating peak impact force. Wire ropes are not ideal straight cylinders; their surfaces exhibit strand ripples and diameter tolerances. The elastic buffer mechanism 46 provides the probe support 41 with a floating degree of freedom along the guide axis A44. When the wire rope experiences slight radial runout, the elastic buffer mechanism 46 utilizes its restoring force to push the detection probe 4 to remain close to or maintain a constant distance from the wire rope, ensuring the magnetic sensing element maintains the set lift-off value. This flexible follow-up characteristic of the elastic buffer mechanism 46 effectively suppresses lift-off noise caused by the jump of the detection probe 4. Without buffering, the detection probe 4 would vibrate erratically, causing severe fluctuations in the baseline signal, which the system could easily misinterpret as wire breakage or wear signals. Therefore, this design filters out mechanical noise at the physical level, providing cleaner and more accurate raw data for the backend central control platform to perform data analysis and processing.

[0038] Furthermore, the elastic buffer mechanism 46 includes a bolt 461, a first compression spring 462, and a second compression spring 463. The bolt 461 passes through the probe bracket 41, and the bolt tail of the bolt 461 is threaded onto the probe bracket 41. The first compression spring 462 is located between the probe bracket 41 and the movable seat 22, and the second compression spring 463 is located between the bolt head of the bolt 461 and the movable seat 22. When the wire rope experiences radial jump or a slight change in diameter due to strand waves, the first compression spring 462 and the second compression spring 463 provide bidirectional elastic buffering for the probe bracket 41 and the magnetizer, using the restoring force to keep the detection probe 4 in close contact with and follow the movement of the wire rope. In addition, the first compression spring 462 and the second compression spring 463, through elastic deformation, can convert the instantaneous mechanical impact kinetic energy of the wire rope into elastic potential energy, which greatly suppresses the peak impact force and avoids hard collisions. Specifically, when the wire rope pushes outward against the detection probe 4, the first compression spring 462 is compressed; when the wire rope suddenly moves away, the second compression spring 463 is compressed, thus forming an effective buffer.

[0039] Furthermore, the probe bracket 41 is equipped with multiple parallel guide shafts B47, which are parallel to the output shaft of the second power mechanism 42.

[0040] The first magnet 431 and the second power mechanism 42 are both mounted on the first connecting shell 433, and the first connecting shell 433 is slidably mounted on each of the guide shafts B47.

[0041] The second magnet 432 is mounted on the second connecting shell 434, which is slidably mounted on each of the guide shafts B47. After the second power mechanism 42 drives the second magnet 432 closer to the first magnet 431 to confine the wire rope within the magnetizer, the second power mechanism 42 and the magnetizer as a whole can move along the guide shaft B47 to accommodate the wire rope's movement, as the wire rope is prone to jumping during movement. The guide shaft B47 cooperates with the guide shaft A44 to accommodate the wire rope's jumping in both directions.

[0042] Furthermore, the encoder assembly includes a connecting bracket and an encoder wheel and an encoder measuring unit mounted on the connecting bracket. The connecting bracket is mounted on the movable seat 22. The encoder wheel is in contact with the wire rope to rotate during the movement of the wire rope. The encoder measuring unit is connected to the encoder wheel to collect the rotation data of the encoder wheel. By having the encoder wheel in contact with the wire rope, the linear displacement of the wire rope is converted into the angular displacement of the encoder wheel through friction transmission, and then converted into a digital pulse signal by the encoder measuring unit. This direct contact measurement method can minimize slippage and accumulated errors, providing a high-precision length measurement reference. The central control platform can synchronize and fuse the magnetic flux leakage detection data with the wire rope movement data in real time. Relying on the precise measurement of the encoder, the system can ensure that the ink is accurately sprayed onto the defect points without spraying off-center or missing areas.

[0043] Furthermore, the system includes a monitoring device that uses high-speed industrial cameras in multiple orientations to take matrix photos and analyzes the images using visual algorithms to determine the equipment's operating status, thereby effectively controlling and correcting deviations. Through its deviation correction function, the monitoring device upgrades the system from a simple signal acquisition device to an intelligent device with visual servo control capabilities. Vision-based deviation correction significantly reduces the risk of equipment malfunction. The introduction of the monitoring device significantly improves the detection accuracy, reliability, and intelligence level of the magnetic flux leakage detection equipment suitable for detecting multiple rows of parallel and synchronously operating wire ropes.

[0044] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
