Description

Technical Field

[0001] This application relates to the technical field of wire rope safety testing equipment, and in particular to a magnetic flaw detection and diameter measurement device for wire ropes. Background Technology

[0002] Wire rope flaw detection devices are a type of device used for safety inspection of wire ropes. Currently, common wire rope flaw detection devices mainly perform safety inspections by installing flaw detection sensors on the inside. The flaw detection sensors have built-in excitation components that can generate a stable detection magnetic field. When the wire rope to be inspected passes through this magnetic field area, the sensing element in the flaw detection sensor will collect the magnetic field signal related to the surface and cross-section of the wire rope in real time. By analyzing the changing characteristics of the magnetic field signal, it is possible to determine whether there is structural damage to the wire rope and deduce the diameter parameters of the wire rope.

[0003] In existing technologies, some wire rope flaw detection devices primarily use external cleaning or ventilation components to clean the outer surface of the wire rope under test, aiming to improve the detection accuracy. However, neither conventional nor these types of devices protect the detection sensors, making them susceptible to misjudgments or inaccurate results due to temperature, humidity, and impurities splashed during cleaning. Furthermore, the movement direction of the sensors is mostly fixed, resulting in poor comprehensiveness in wire rope flaw detection. In addition, the external cleaning and ventilation components are usually installed independently rather than integrated with the device itself. This significantly increases the lateral width and longitudinal height of the wire rope flaw detection device, resulting in a large overall structure and occupying a lot of space. This makes it impossible to perform flaw detection operations on wire ropes installed in confined spaces, greatly limiting the device's applicability and significantly restricting its use, failing to meet the wire rope flaw detection needs under various working conditions. Summary of the Invention

[0004] To reduce the problems of inaccurate test results and poor comprehensiveness of wire rope flaw detection devices, this application provides a magnetic flaw detection and diameter measurement device for wire ropes.

[0005] This application provides a magnetic flaw detection and diameter measurement device for steel wire ropes, adopting the following technical solution: A magnetic flaw detection and diameter measurement device for steel wire rope includes: a flaw detection body, a pair of flaw detection sensors, an integrated protection assembly, a pair of reciprocating swing assemblies, and a pair of climbing and cleaning assemblies. The flaw detection body is arranged in an "n" shape, with a pair of flaw detection sensors symmetrically embedded in its inner wall. The integrated protection assembly includes multiple sets of protective side plates, a pair of protective frames, multiple sets of cleaning brushes, an air curtain return air plate, an air curtain exhaust air plate, a limit spring, a dustproof cloth, a pair of control air boxes, a pair of partition plates, a pair of exhaust fans, a pair of return air ducts, a pair of dust filters, a pair of guide air ducts, multiple sets of heating elements, multiple sets of cooling elements, and a pair of outlet air ducts. The multiple sets of protective side plates are thin-plate components, fixedly connected to the inner wall of the flaw detection body in pairs, and symmetrically arranged on both sides of the flaw detection sensors. The protective frames are hollow components with openings on both sides, with an opening on the side closest to the protective side plates. The protective side plate has a sliding groove into which it slides. A limit spring is installed within the groove, with both ends of the limit spring fixedly connected to the protective side plate and the outer protective frame, respectively. The cleaning brush is fixedly connected to the side of the outer protective frame away from the protective side plate. Dustproof cloths are provided on both the upper and lower sides of the protective side plate, and these cloths are fixedly connected to the sides of the outer protective frame. The protective side plate, outer protective frame, cleaning brush, and dustproof cloths together form a semi-enclosed protective cover with an opening on one side. The air curtain return air plate and air curtain exhaust air plate are both hollow components with openings at both ends, fixedly connected to the upper and lower inner side walls of the outer protective frame, respectively. A pair of control air boxes are symmetrically fixedly installed on the outside of the flaw detection body. The partition plates are fixedly installed inside the control air box, dividing it into an upper reflux chamber and a lower temperature control chamber. The exhaust fan is fixedly installed inside the partition plates, with its air outlet facing the lower temperature control chamber. The reflux duct is located above the control air box, with both ends connected to the control air box and the air curtain return air plate, respectively. The dust filter is fixedly installed inside the upper reflux chamber. The guide duct is a tubular component with open ends, fixedly installed below the exhaust fan. Multiple sets of heating and cooling elements are staggered on the outer wall of the guide duct. A pair of outlet ducts are located below a pair of control air boxes, with both ends connected to the guide duct and the air curtain exhaust plate, respectively. A pair of reciprocating oscillating components are... The reciprocating swing assembly is fixedly installed on the upper and lower sides of the flaw detection body. The reciprocating swing assembly includes a linkage, a swing half gear, and a drive component. The linkage is fixedly connected to the flaw detection body. The swing half gear is fixedly sleeved on the outside of the linkage and coaxially arranged with the linkage. The drive component is used to drive the swing half gear to reciprocate. A pair of climbing cleaning assemblies are symmetrically integrated on both ends of the flaw detection body along the axial direction of the flaw detection body. The climbing cleaning assembly includes multiple climbing wheels, a scraping cleaning component, and a lubrication oiling disc. The multiple climbing wheels are respectively arranged on the upper and lower sides of the flaw detection body. The scraping cleaning component is arranged above the climbing wheels and below the climbing wheels.

[0006] By adopting the above technical solution, in practical applications, multiple sets of flaw detection sensors are assembled and fixed using the flaw detection body. These sensors can be synchronously moved to the outside of the wire rope by directly placing the flaw detection body over the wire rope along the notch. Subsequently, the climbing and cleaning assembly controls the flaw detection body to climb the wire rope, enabling the sensors to detect flaws at different heights. During the upward movement of the flaw detection body, the reciprocating swing assembly drives it to swing back and forth, allowing the sensors to perform circumferential detection of the wire rope, thus increasing the detection range. Furthermore, during the detection process, protective side plates, a protective frame, and cleaning brushes provide dust protection for the sensors, preventing them from becoming dirty due to dust or oil on the outside of the wire rope during movement, thereby improving the detection accuracy. In addition, the combination of the air curtain return air plate and the air curtain exhaust air plate can provide auxiliary dust protection for the flaw detection sensor and regulate the temperature and humidity, further improving the detection accuracy of the flaw detection sensor.

[0007] Optionally, a cleaning duct is integrally formed on one side of the air curtain exhaust plate, and the air outlet of the cleaning duct is set towards the flaw detection sensor. Anti-clogging filters are fixedly connected to the openings on the corresponding sides of the air curtain return air plate and the air curtain exhaust plate.

[0008] By adopting the above technical solution, some of the air inside the air curtain exhaust plate can be blown towards the flaw detection sensor along the clean air duct. This method can not only clean the flaw detection sensor by blowing away dust, but also regulate the temperature and humidity of the flaw detection sensor, further ensuring the detection accuracy of the flaw detection sensor.

[0009] Optionally, the dust filter is cylindrical with its opening facing the return air duct, and the guide air duct is frustum-shaped with its lower inner diameter smaller than its upper inner diameter.

[0010] By adopting the above technical solution, the air transported by the return air duct is filtered through a dust filter, avoiding secondary contamination of the flaw detection sensor during subsequent air circulation. The frustum-shaped guide duct accelerates the flow of air transported by the exhaust fan.

[0011] Optionally, the reciprocating swing assembly further includes a positioning frame, a fixed bracket, a miniature swing motor, and a transmission gear, wherein the positioning frame is rotatably sleeved on the outside of the linkage component.

[0012] By adopting the above technical solution, the positioning frame plays a role in fixing and limiting the fixed bracket.

[0013] Optionally, the fixed bracket is fixedly installed on one side of the positioning frame, the micro swing motor is fixedly installed above the fixed bracket, and the transmission gear is fixedly connected to the output shaft of the micro swing motor and meshes with the swing half gear.

[0014] By adopting the above technical solution, the fixed bracket is used to install and fix the micro swing motor, which provides power. By controlling the operation of the micro swing motor, the transmission gear is rotated and driven, and the reciprocating swing control of the flaw detection body can be achieved through the meshing of the transmission gear and the swing half gear.

[0015] Optionally, the climbing and cleaning assembly further includes a pair of frames, multiple adjusting bolt rods, multiple wheel frames, multiple guide rods, and multiple compression springs. The pair of frames are symmetrically fixed above the positioning frame. The pair of adjusting bolt rods are threaded onto both sides of the pair of frames. The multiple wheel frames are rotatably connected to the side of the multiple adjusting bolt rods close to the linkage.

[0016] By adopting the above technical solution, the frame serves as an assembly limit for the adjusting bolt rod, and the wheel frame serves as an assembly limit for the climbing wheel. By controlling the rotation of the adjusting bolt rod, the adjusting bolt rod can drive the wheel frame to slide horizontally under the action of the thread, thereby adjusting the distance between the climbing wheel and the steel wire rope to be tested. This allows the climbing cleaning component to clamp and limit steel wire ropes of different diameters.

[0017] Optionally, the number of adjusting bolt rods and wheel frames is four, arranged symmetrically in pairs on both sides of the frame, and the multiple climbing wheels are respectively rotatably installed in multiple wheel frames.

[0018] By adopting the above technical solution, the climbing wheel is assembled and limited by the wheel frame, which facilitates the synchronous adjustment of the climbing wheel by adjusting the position of the wheel frame.

[0019] Optionally, the multiple guide rods are fixedly connected to multiple wheel frames and slide in cooperation with the frame, and the multiple compression springs are respectively disposed at the connection between the multiple climbing wheels and the wheel frames.

[0020] By adopting the above technical solution, the sliding cooperation between the guide rod and the frame plays a role in adjusting the wheel frame, ensuring the stability of the wheel frame adjustment. The contraction and reset of multiple compression springs provide support and limit for the climbing wheel, preventing excessive wear or jamming between the climbing wheel and the steel wire rope under test during actual operation.

[0021] Optionally, the climbing cleaning assembly also includes a climbing motor, which is fixedly mounted on one side of the wheel frame, and the output shaft of the climbing motor is fixedly connected to a single climbing wheel.

[0022] By adopting the above technical solution, the climbing wheel is rotated by controlling the operation of the climbing motor.

[0023] Optionally, the scraping and cleaning component is a tubular member with openings at both ends, and the inner diameter of the middle part of the scraping and cleaning component is smaller than the inner diameter of both ends. The lubrication and oiling disc is arranged in a trumpet shape and is filled with oil-soaked cotton.

[0024] By adopting the above technical solution, the scraping and cleaning component can collect and store the scraped oil, preventing oil drips from adversely affecting the sensor's detection process and causing environmental pollution. By placing oil-soaked cotton inside the lubrication pad, the tested wire rope can be protected with oil, preventing damage to the wire rope during the testing process.

[0025] In summary, the embodiments of the present invention provide a magnetic flaw detection and diameter measurement device for steel wire ropes, which includes at least one of the following beneficial technical effects: 1. By setting the flaw detector body to an n-type structure, the process of fitting the flaw detector body onto the outside of the wire rope is simplified. Compared with the traditional snap-fit ​​type, it has the advantages of simple structure and convenient operation. It can quickly complete the assembly and alignment with the wire rope to be tested, and greatly improve the operation efficiency of flaw detection. 2. By setting an integrated protection component on the outside of the flaw detection sensor, the flaw detection sensor can be dustproofed and its temperature and humidity can be controlled. This effectively isolates dust impurities and splashed oil in the detection environment, avoids interference from temperature and humidity fluctuations, and fundamentally reduces the adverse effects of various environmental factors on the detection accuracy of the flaw detection sensor, significantly improving the accuracy and stability of wire rope flaw detection. 3. By setting reciprocating swing components at the upper and lower ends of the flaw detection body, the flaw detection sensor can be reciprocated during the detection process, thereby enabling circumferential detection of the steel wire rope under test, which greatly improves the detection range of the steel wire rope, avoids detection blind spots, and improves the comprehensiveness of flaw detection of the steel wire rope. 4. The integrated protection components are integrated with the flaw detection body, and the reciprocating swing components and climbing cleaning components are extended along the axial direction of the wire rope. There are no redundant external components. Under the premise of achieving multiple function optimization, the overall size of the flaw detection device is greatly reduced, making the wire rope flaw detection device have the advantages of small structure, compact layout and simplified size, which greatly improves the applicability of the wire rope flaw detection device.

[0028] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0029] Combination Figure 1 and Figure 2 This application discloses a magnetic flaw detection and diameter measurement device for steel wire ropes, comprising: a flaw detection body 1, multiple sets of flaw detection sensors 2, an integrated protection component 3, a pair of reciprocating swing components 4, and a pair of climbing and cleaning components 5. In practical applications, the multiple sets of flaw detection sensors 2 are assembled and fixed by the flaw detection body 1, and the multiple sets of flaw detection sensors 2 can be synchronously moved to the outside of the steel wire rope by directly fitting the flaw detection body 1 onto the outside of the steel wire rope along the notch of the flaw detection body 1. Subsequently, the operation of the climbing and cleaning components 5 can be controlled to drive the flaw detection body 1 to climb along the steel wire rope, thereby enabling the multiple sets of flaw detection sensors 2 to perform flaw detection on steel wire ropes at different horizontal heights. During the ascent of the flaw detection body 1, the reciprocating swing components 4 drive the flaw detection body 1 to reciprocate, enabling the multiple sets of flaw detection sensors 2 to perform circumferential detection on the steel wire rope, thus improving the detection range. Furthermore, during the testing process, the flaw detection sensor 2 is protected from dust by the protective side plate 301, the protective frame 302, and the cleaning brush 303. This prevents the flaw detection sensor 2 from becoming dirty due to dust or oil stains on the outside of the wire rope during the movement of the flaw detection body 1, thus improving the detection accuracy of the flaw detection sensor 2. In addition, the integrated protection component 3 can provide auxiliary dust protection and adjust the temperature and humidity of the flaw detection sensor 2, further improving the detection accuracy of the flaw detection sensor 2.

[0030] The flaw detection body 1 is arranged in an n-shape. It can be placed on the outside of the steel wire rope to be tested by direct clamping, which is more convenient than the traditional snap-fit ​​type. In addition, the position of the flaw detection sensor 2 and the steel wire rope to be tested can be observed in detail during the detection process.

[0031] Combination Figure 2 , Figure 3 and Figure 4 A pair of flaw detection sensors 2 are symmetrically embedded on the inner wall of the flaw detection body 1. There are four flaw detection sensors 2, which are symmetrically arranged in pairs inside the flaw detection body 1. The flaw detection sensors 2 generate a stable detection magnetic field, and the change in the magnetic field signal after the steel wire rope passes through the detection magnetic field can be used to determine whether there is an abnormality on the outside of the steel wire rope.

[0032] Combination Figure 2 and Figure 3The integrated protection components 3 are respectively disposed on the outside of multiple sets of flaw detection sensors 2. The integrated protection components 3 include multiple sets of protective side plates 301, a pair of protective outer frames 302, multiple sets of cleaning brushes 303, an air curtain return air plate 304, an air curtain exhaust air plate 305, a limit spring 306, a dustproof cloth 307, a pair of control air boxes 308, a pair of partition plates 309, a pair of exhaust fans 310, a pair of return air ducts 311, a pair of dust filters 312, a pair of guide air ducts 313, multiple sets of heating elements 314, multiple sets of cooling elements 315, and a pair of air outlet ducts 316. In practical applications, the cooperation of the protective side plates 301, protective outer frames 302, and cleaning brushes 303 provides semi-enclosed protection for the flaw detection sensors 2, reducing the adverse effects of dust, humidity, and oil stains on the outside of the wire rope on the detection of the flaw detection sensors 2. Meanwhile, the combination of the air curtain return air plate 304 and the air curtain exhaust air plate 305 can form an isolation air curtain outside the flaw detection sensor 2, further reducing the adverse effects of environmental factors on the detection results of the flaw detection sensor 2 and improving the detection accuracy of the flaw detection sensor 2.

[0033] Combination Figure 2 and Figure 3 Multiple sets of protective side plates 301 are thin plate-type components, fixedly connected to the inner wall of the flaw detection body 1 in pairs, and symmetrically arranged on both sides of the flaw detection sensor 2. The protective outer frame 302 is a hollow component with openings on both sides, and a sliding groove is provided on the side close to the protective side plate 301, into which the protective side plate 301 slides. This allows the protective side plate 301 and the protective outer frame 302 to contract and change according to the different diameters of the wire rope. The protective side plate 301, protective outer frame 302, cleaning brush 303, and dustproof cloth 307 work together to form a semi-enclosed protective cover with an opening on one side, used to protect the flaw detection sensor 2 from dust.

[0034] Specifically, a temperature and humidity sensor is fixedly installed on the inner wall of the protective frame 302. The temperature and humidity sensor can detect the temperature and humidity outside the flaw detection sensor 2 in real time, avoiding inaccurate detection results due to temperature and humidity factors.

[0035] Combination Figure 2 and Figure 3 A limit spring 306 is installed inside the slide groove. The two ends of the limit spring 306 are fixedly connected to the protective side plate 301 and the protective outer frame 302, respectively. Dustproof cloths 307 are installed on both the upper and lower sides of the protective side plate 301, and the dustproof cloths 307 are fixedly connected to the sides of the protective outer frame 302. The connection and limitation between the protective side plate 301 and the protective outer frame 302 are achieved through the contraction and reset of multiple sets of limit springs 306. The dustproof cloths 307 ensure the effective dust protection of the top of the protective side plate 301 by the protective outer frame 302.

[0036] Combination Figure 2and Figure 3 The cleaning brush 303 is fixedly connected to the protective frame 302 on the side away from the protective side plate 301. The interaction between the cleaning brush 303 and the steel wire rope under test allows for a second cleaning of the outer side of the steel wire rope, further reducing the adverse effects of oil contamination on the accuracy of the test.

[0037] Combination Figure 4 , Figure 5 and Figure 6 Both the air curtain return air plate 304 and the air curtain exhaust air plate 305 are hollow components with openings at both ends, and are fixedly connected to the upper and lower inner side walls of the protective outer frame 302 respectively, to form an isolation air curtain. The isolation air curtain provides further dust protection for the flaw detection sensor 2. This prevents dirt from adhering to the outside of the flaw detection sensor 2 during cleaning by the cleaning brush 303, ensuring the detection accuracy of the flaw detection sensor 2. Simultaneously, the temperature and humidity of the flaw detection sensor 2 can be controlled non-contactly by adjusting the temperature and humidity of the isolation air curtain, avoiding the adverse effects of ambient temperature and humidity on the detection accuracy of the flaw detection sensor 2, and greatly improving the detection accuracy of the flaw detection sensor 2.

[0038] Combination Figure 4 and Figure 5 A cleaning duct 317 is integrally formed on one side of the air curtain exhaust plate 305. The air outlet of the cleaning duct 317 is positioned facing the flaw detection sensor 2. Anti-clogging filters 318 are fixedly connected to the openings on the corresponding sides of the air curtain return air plate 304 and the air curtain exhaust plate 305. This allows some air inside the air curtain exhaust plate 305 to be blown along the cleaning duct 317 to multiple sets of flaw detection sensors 2. By blowing air onto multiple sets of flaw detection sensors 2, the cleanliness of the surface of the flaw detection sensors 2 is further ensured. At the same time, the temperature and humidity outside the flaw detection sensors 2 can be synchronously controlled by controlling the blowing temperature.

[0039] Combination Figure 4 The integrated protection component 3 also includes a control air box 308, a partition plate 309, and an exhaust fan 310. The control air box 308 is fixedly connected to the outer wall of the flaw detection body 1. The partition plate 309 is fixedly installed inside the control air box 308, dividing the control air box 308 into an upper reflux chamber and a lower temperature control chamber. By dividing the control air box 308 into an upper reflux chamber and a lower temperature control chamber through the partition plate 309, it is convenient to provide dust filtration and temperature control space for the air recirculated into the protective frame 302.

[0040] Combination Figure 4 The exhaust fan 310 is fixedly installed inside the control air box 308, and the air outlet of the exhaust fan 310 is set towards the lower temperature control cavity. By controlling the operation of the exhaust fan 310, the air in the upper return cavity is continuously transported to the lower temperature control cavity, thereby enabling the air in the control air box 308 to be continuously output and drawn back.

[0041] Combination Figure 4 The integrated protection component 3 also includes a return air duct 311 and a dust filter 312. The two ends of the return air duct 311 are connected to the air curtain return air plate 304 and the upper return cavity, respectively. This allows the air inside the protective frame 302 to flow back from bottom to top along the air curtain return air plate 304 and the return air duct 311 into the control air box 308.

[0042] Combination Figure 4 The dust filter 312 is fixedly installed inside the upper return cavity. The dust filter 312 is cylindrical, with its opening facing the return air duct 311. The return air duct 311 connects the air curtain return air plate 304 and the control air box 308, thereby facilitating the subsequent dust filtration of the return air through the dust filter 312, ensuring the cleanliness of the flaw detection sensor 2 during use, and reducing the adverse effects of dust and other impurities on the detection accuracy of the flaw detection sensor 2.

[0043] Combination Figure 4 The integrated protection component 3 also includes a guide duct 313, multiple sets of heating elements 314, multiple sets of cooling elements 315, and an exhaust duct 316. The guide duct 313 is fixedly installed below the partition plate 309 and sleeved on the outside of the exhaust fan 310. The multiple sets of heating elements 314 and multiple sets of cooling elements 315 are staggered on the outside of the guide duct 313. The guide duct 313 guides, limits, and accelerates the air discharged from the exhaust fan 310 during operation. By controlling the operation of the multiple sets of heating elements 314 or multiple sets of cooling elements 315, the air transported in the guide duct 313 can be heated or cooled.

[0044] Among them, the heating element 314 and the cooling element 315 can be semiconductor cooling elements.

[0045] Combination Figure 4 The air guide duct 313 is a tube with openings at both ends, and the inner diameter of the lower end of the air guide duct 313 is smaller than the inner diameter of the upper end. When air flows in the air guide duct 313, the flow velocity will be lower at the end with a larger diameter and higher at the end with a smaller diameter due to the influence of the diameter. This allows the air guide duct 313 to accelerate the gas discharged from the exhaust fan 310 a second time.

[0046] Combination Figure 4 The air outlet ducts 316 are respectively located below the control air box 308, and both ends of the air outlet ducts 316 are connected to the guide duct 313 and the air curtain exhaust plate 305, respectively. The air outlet ducts 316 serve to connect the air curtain exhaust plate 305 and the guide duct 313, so that the air that has been accelerated twice in the guide duct 313 can be transported to the air curtain exhaust plate 305 along the guide duct 313.

[0047] Combination Figure 7 and Figure 8 A pair of reciprocating oscillating components 4 are fixedly disposed on the upper and lower sides of the flaw detection body 1, respectively. The reciprocating oscillating component 4 includes a linkage 401 and an oscillating half gear 402. The linkage 401 is fixedly connected to the flaw detection body 1. The flaw detection sensor 2 is synchronously rotated by driving the linkage 401 to rotate.

[0048] Combination Figure 7 and Figure 8 The oscillating half gear 402 is fixedly sleeved on the outside of the linkage 401. The linkage 401 is rotated by engaging the oscillating half gear 402.

[0049] Both the linkage 401 and the swing half-gear 402 are provided with clearance grooves that match the flaw detection body 1. This avoids interference between the linkage 401, the swing half-gear 402 and the steel wire rope to be tested during assembly.

[0050] Combination Figure 8 and Figure 9 A positioning frame 403 is fitted on the outer side of the linkage 401, and the positioning frame 403 is rotatably connected to the linkage 401. The opening of the clearance groove simplifies the process of fitting the entire device onto the outside of the wire rope, improving ease of use. The positioning frame 403 serves to limit the assembly of the linkage 401.

[0051] Combination Figure 7 and Figure 8 The reciprocating swing assembly 4 also includes a fixed bracket 404, a micro swing motor 405, and a transmission gear 406. In use, the operation of the micro swing motor 405 can drive the transmission gear 406 to rotate, thereby causing the linkage 401 to rotate synchronously under the meshing action of the swing half gear 402 and the transmission gear 406.

[0052] Combination Figure 7 and Figure 8 A fixed bracket 404 is fixedly mounted on one side of the positioning frame 403. A miniature swing motor 405 is fixedly mounted on the fixed bracket 404. A transmission gear 406 is fixedly connected to the output shaft of the miniature swing motor 405 and meshes with the swing half gear 402. The fixed bracket 404 installs and fixes the miniature swing motor 405, which provides power. By controlling the operation of the miniature swing motor 405, the transmission gear 406 is rotated and driven, thereby enabling the reciprocating swing control of the flaw detection body 1 through the meshing of the transmission gear 406 and the swing half gear 402.

[0053] Combination Figure 9 and Figure 10 A pair of climbing and cleaning components 5 are set on the upper and lower sides of the flaw detection body 1 to drive the flaw detection body 1 to climb up and down along the wire rope.

[0054] Combination Figure 9 and Figure 10 The climbing cleaning component 5 includes a pair of frames 501, which are symmetrically fixed above the positioning frame 403. The frames 501 serve as assembly limits for the adjusting bolt rod 502.

[0055] Combination Figure 9 and Figure 10 Each pair of frames 501 has an adjusting bolt rod 502 threadedly connected to its upper part. By controlling the rotation of the adjusting bolt rod 502, the adjusting bolt rod 502 can drive the wheel frame 503 to slide horizontally under the action of the thread, thereby adjusting the distance between the climbing wheel 505 and the steel wire rope to be tested, so that the climbing cleaning component 5 can clamp and limit the steel wire rope to be tested with different diameters.

[0056] Combination Figure 9 and Figure 10 The end of the adjusting bolt rod 502 close to the linkage 401 is rotatably connected to the wheel frame 503. The wheel frame 503 serves to limit the assembly of the climbing wheel 505.

[0057] Combination Figure 9 Each pair of frames 501 has a guide rod 504 slidably inserted inside it, and the guide rod 504 is fixedly connected to the wheel frame 503. The sliding engagement between the guide rod 504 and the frame 501 plays a role in sliding adjustment of the wheel frame 503, ensuring the adjustment stability of the wheel frame 503.

[0058] Combination Figure 9 A pair of climbing wheels 505 are slidably connected to the side of the wheel frame 503 away from the adjusting bolt rod 502. The rotation of the climbing wheels 505 allows the traction device to climb and ascend along the steel wire rope under test. Multiple compression springs 506 connect the climbing wheels 505 to the wheel frame 503. The contraction and reset of the compression springs 506 provide support and limit for the climbing wheels 505, preventing excessive wear or jamming between the climbing wheels 505 and the steel wire rope under test during actual operation.

[0059] Specifically, a pair of climbing wheels 505 rotate synchronously via belt drive or gear belt drive.

[0060] Combination Figure 9 A climbing motor 507 is fixedly connected to one side of a single climbing wheel 505. The climbing wheel 505 is rotated by controlling the operation of the climbing motor 507.

[0061] Combination Figure 9 and Figure 10A pair of scraping and cleaning components 508 are fixedly connected to the upper side of a pair of upper wheel frames 503. The scraping and cleaning components 508 scrape and clean the oil stains on the outside of the steel wire rope under test by interacting with the outside of the steel wire rope under test.

[0062] Specifically, both the scraping and cleaning component 508 and the lubrication and oiling disc 509 are tubular components with openings at both ends. The inner diameter of the middle part of the scraping and cleaning component 508 is smaller than the inner diameters at both ends, which facilitates the scraping and cleaning component 508 to move along the wire rope to scrape off and collect the oil stains adhering to the outside of the wire rope. This avoids the oil stains dripping and causing adverse effects on the detection process of the flaw detection sensor 2, as well as causing environmental pollution.

[0063] Combination Figure 9 and Figure 10 A pair of lubrication pads 509 are fixedly connected to the lower side of a pair of wheel frames 503. The lubrication pads 509 are funnel-shaped and filled with oil-soaked cotton. By placing oil-soaked cotton in the lubrication pads 509, the tested wire rope can be protected with oil, avoiding damage to the wire rope during the testing process.

[0064] The working principle of this application is as follows: First, before installing the flaw detector body 1, the pair of protective frames 302 can be separated manually or by other means. Then, align the notch of the flaw detector body 1 with the wire rope to be tested, move the flaw detector body 1, and place it on the outside of the wire rope to be tested. After placement, release the pair of protective frames 302, which will reset under the action of the limit spring 306.

[0065] At this point, a pair of cleaning brushes 303 will contact the outer side of the steel wire rope under test. The linkage 401 and the swing half gear 402 are sleeved on the outer side of the steel wire rope under test, and the climbing wheels 505 inside the wheel frame 503 are distributed on both sides of the steel wire rope under test. Subsequently, the climbing wheels 505 can be moved and controlled by manually controlling the rotation of the adjusting bolt rod 502, so that the climbing wheels 505 clamp the steel wire rope under test.

[0066] Then, multiple sets of flaw detection sensors 2 are connected to the controller to begin flaw detection of the steel wire rope under test. During the detection process, the climbing motor 507 is controlled to drive the climbing wheels 505 to rotate, and the rotation of multiple climbing wheels 505 drives the flaw detection body 1 to climb up the steel wire rope under test. During the ascent, the scraping and cleaning component 508 scrapes and collects the oil and impurities on the outside of the steel wire rope under test, reducing the adverse effects of oil and impurities on the accuracy of subsequent detection. Moreover, the collection of oil and impurities will not contaminate the components below, facilitating subsequent cleaning of oil and impurities. At the same time, during the ascent, multiple sets of flaw detection sensors 2 perform flaw detection on the steel wire rope under test at different horizontal heights.

[0067] Meanwhile, by controlling the reciprocating rotation of the output shaft of the micro swing motor 405, the flaw detection body 1 is made to swing back and forth under the action of the linkage 401, the swing half gear 402 and the transmission gear 406, thereby enabling multiple sets of flaw detection sensors 2 to perform all-round detection of the steel wire rope under test, improving the detection range and detection reliability of the flaw detection sensors 2.

[0068] Furthermore, during the testing process, the multiple sets of flaw detection sensors 2 are semi-enclosed and protected by the protective side plate 301, protective frame 302, cleaning brush 303, and dustproof cloth 307, which improves the detection stability of the multiple sets of flaw detection sensors 2. In addition, the cleaning brush 303 can assist in cleaning the steel wire rope under test, further reducing the adverse effects of oil and impurities on the outer side of the steel wire rope on the test results.

[0069] During the testing process, the operation of the exhaust fan 310 causes the air inside the protective frame 302 to circulate along the return air duct 311, control air box 308, guide air duct 313, and outlet air duct 316. An isolation air curtain is formed between the multiple sets of flaw detection sensors 2 and the steel wire rope under test through exhaust via the air curtain exhaust plate 305 and air extraction via the air curtain return air plate 304. This isolation air curtain further protects the flaw detection sensors 2 from dust. It prevents dirt from adhering to the outside of the flaw detection sensors 2 during cleaning by the cleaning brush 303, ensuring the detection accuracy of the flaw detection sensors 2. Simultaneously, the temperature and humidity of the flaw detection sensors 2 can be controlled non-contactly by adjusting the isolation air curtain, avoiding the adverse effects of environmental temperature and humidity on the detection accuracy of the flaw detection sensors 2, and greatly improving the detection accuracy of the flaw detection sensors 2.

[0070] During the inspection process, a stable detection magnetic field is generated by the excitation component of the flaw detector sensor 2. The steel wire rope under test is placed in this magnetic field environment. When the surface or cross-sectional condition of the steel wire rope changes, such as damage or diameter fluctuation, it will cause an abnormal magnetic field distribution. The sensing element of the flaw detector sensor 2 captures this abnormal signal and converts it into an electrical signal, which is then transmitted to the controller. The controller processes the received electrical signal and transmits the processed data stream to the software. The software analyzes the data stream using a preset algorithm. On the one hand, it generates a damage degree-time relationship graph to visually present the changing trend of the damage state of the steel wire rope under test and assist in judging whether there is structural damage. On the other hand, it calculates and outputs the diameter measurement value of the steel wire rope under test, thus completing the diameter monitoring.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
