Description

Technical Field

[0001] This invention relates to the field of parallel steel wire rope detection technology, specifically to magnetic sensitive element assemblies, small-pitch multi-rope parallel steel wire rope detection probes and systems. Background Technology

[0002] As a flexible rope, wire rope serves functions such as power transmission, load bearing, and positioning, and is therefore widely used in industrial production, manufacturing, and transportation, becoming a key load-bearing component in various industries. Regular inspection of wire ropes is essential for safe operation.

[0003] Currently, there are no testing devices available on the market for small-pitch multi-rope parallel steel wire ropes. This invention presents a novel intelligent testing solution for small-pitch multi-rope parallel steel wire ropes. Summary of the Invention

[0004] This invention addresses the technical problems existing in the prior art by providing a magnetic sensitive element assembly, a small-pitch multi-rope parallel steel wire rope detection probe and system.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A magnetic sensing element assembly includes: two magnetic sensing elements, each of which includes a base, a sensitive element H-type, and a sensitive element O-type. The two bases are distributed opposite each other, and their opposite sides are provided with multiple pairs of rope grooves, which form a detection channel for the steel wire rope to be tested to pass through. Each base has a through detection port at both ends and between two adjacent rope grooves. Multiple sensitive elements H-type and multiple sensitive elements O-type are respectively installed in the detection port area on the back side of the corresponding rope groove.

[0006] The beneficial effects of this invention are: during the detection process, multiple sensitive components H-type and O-type are used to simultaneously and effectively detect damage types such as broken wires and wear on the steel wire rope under test, resulting in a more comprehensive detection of damage types and high accuracy.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, multiple H-shaped sensitive components are sequentially and alternately distributed on the back side of multiple rope grooves, and the two ends of each H-shaped sensitive component extend to the corresponding two detection ports.

[0009] The advantages of adopting the above-mentioned further scheme are that the structure is simple, the multiple sensitive components are distributed in an interleaved manner, which is more reasonable so as to detect different types of damage to the steel wire rope under inspection, and can avoid mutual interference between two adjacent sensitive components, resulting in higher detection accuracy.

[0010] Furthermore, multiple sensitive components are arranged side-by-side or staggered on the back side of multiple rope grooves.

[0011] The advantages of adopting the above-mentioned further scheme are that the structure is simple and the O-type distribution of multiple sensitive components is more reasonable, so as to detect different types of damage to the steel wire rope under inspection.

[0012] Furthermore, the H-type and O-type sensitive components are respectively customized resistance type sensors.

[0013] The advantages of adopting the above-mentioned further solution are that the structure is simple and the customized resistance-type sensitive components, H-type and O-type sensors, are evenly and reasonably arranged so as to simultaneously detect the wire rope's broken wires and wear and other damage types, and the detection accuracy is more precise.

[0014] The present invention also relates to a small-pitch multi-rope parallel steel wire rope detection probe, including an upper magnetizer assembly, a lower magnetizer assembly, and a magnetic sensitive element assembly as described above, wherein the upper magnetizer assembly and the lower magnetizer assembly are distributed opposite to each other on both sides of the two bases.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that during the detection process, magnetic flux leakage testing uses the upper magnetizer assembly and the lower magnetizer assembly to generate a magnetic field, and generates a magnetic flux leakage field at the defect of the wire rope. At the same time, the magnetic flux leakage signal is detected by two magnetic sensitive elements to realize the detection of wire rope defects. In addition, the present invention provides a small-pitch multi-rope parallel steel wire rope detection probe. The probe has a compact structure and reasonable design, and can realize intelligent detection of damage types such as wire breakage and wear in multi-rope parallel steel wire ropes. The detection is convenient, efficient and accurate.

[0016] Furthermore, it also includes two pairs of cable trays, which are distributed opposite to each other on both sides of the two seats, and each pair of cable trays is distributed opposite to each other; multiple pairs of support rope grooves are evenly spaced and distributed opposite to each other on the opposite sides of the two pairs of cable trays, and the multiple pairs of support rope grooves form multiple through channels, and the multiple through channels are respectively connected to multiple detection channels.

[0017] The advantages of adopting the above-mentioned further scheme are that the structure is simple and the design is reasonable. It uses two pairs of cable trays to support multiple rows of steel wire ropes, which facilitates the inspection of the steel wire ropes.

[0018] Furthermore, the diameter of the support rope groove is smaller than the diameter of the rope groove.

[0019] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. On the one hand, the depth of the support groove is less than the depth of the rope groove, which can prevent the wire rope from contacting the rope groove, protect the rope groove, and avoid wear. On the other hand, the smaller diameter of the support groove compared to the diameter of the rope groove makes it easier to detect damage types such as broken wires or wear on the wire rope, making the detection more convenient.

[0020] Furthermore, it also includes an upper shell and a lower shell, the upper shell and the lower shell being distributed opposite to each other, with openings on both sides; the upper magnetizer assembly, the lower magnetizer assembly and the two bases are respectively distributed in the area enclosed by the upper shell and the lower shell.

[0021] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. The upper and lower shells form an assembly space to assemble the upper magnetizer assembly, the lower magnetizer assembly and the two magnetic sensitive elements. The assembly is convenient and more neat and beautiful.

[0022] Furthermore, it also includes an encoder, which is mounted on the upper housing or the lower housing, for locating the flaw detection area of ​​the wire rope to be inspected.

[0023] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. During the wire rope inspection process, the encoder is used to locate the wire rope being inspected in order to determine the location of the damage type such as broken wires or wear, which greatly improves the accuracy.

[0024] This invention also relates to an intelligent detection system for parallel multi-rope steel wire ropes with small spacing, including a control module and a detection probe for parallel multi-rope steel wire ropes with small spacing as described above. The upper magnetizer assembly, the lower magnetizer assembly, and multiple H-type and O-type sensitive components are respectively communicatively connected to the control module.

[0025] The beneficial effect of adopting the above-mentioned further solutions is that the present invention provides a small-pitch multi-rope parallel steel wire rope intelligent detection system. The detection system has a compact structure and reasonable design, and can realize intelligent detection of damage types such as broken wires and wear in multi-rope parallel steel wire ropes. The detection is convenient, efficient, and accurate. Attached Figure Description

In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0033] Example 1 like Figures 1 to 5As shown, this embodiment provides a magnetic sensing element assembly, including: two magnetic sensing elements 1, each of the two magnetic sensing elements 1 including a base 11, a sensitive element H-type 12 and a sensitive element O-type 13, the two bases 11 being distributed opposite to each other, and having multiple pairs of rope grooves 14 on their opposite sides, the multiple pairs of rope grooves 14 forming a detection channel for the steel wire rope to be tested to pass through; each base 11 has a through detection port 15 at both ends and between two adjacent rope grooves 14, and multiple sensitive elements H-type 12 and multiple sensitive elements O-type 13 are respectively installed in the detection port 15 area on the back side of the corresponding rope groove 14.

[0034] During the testing process, multiple sensitive components H-type 12 and O-type 13 are used to simultaneously and effectively detect damage types such as broken wires and wear on the steel wire rope under test. The detection of damage types is comprehensive and highly accurate.

[0035] Preferably, in this embodiment, the base 11 is preferably a long strip-shaped block structure.

[0036] In addition, multiple rope grooves 14 are integrally formed with the seat body 11.

[0037] Alternatively, the aforementioned seat 11 can also adopt a rectangular frame structure, and multiple semi-circular tubes are evenly spaced inside the seat 11, with the multiple semi-circular tubes equivalent to the aforementioned multiple rope grooves 14.

[0038] Preferably, in this embodiment, the size of the detection ports 15 located at both ends of the base 11 can be the same as the size of the detection port 15 located in the middle of the base 11, or they can be different.

[0039] In addition, the size of the detection ports 15 located at both ends of the base 11 is larger than the size of the detection port 15 located in the middle of the base 11.

[0040] The magnetic sensitive element assembly provided in this embodiment has a compact structure and reasonable design. It can realize intelligent detection of damage types such as broken wires and wear in multi-rope parallel steel wire ropes. The detection is convenient, efficient and accurate.

[0041] Example 2 Based on Embodiment 1, in this embodiment, multiple sensitive H-shaped components 12 are sequentially and alternately distributed on the back side of multiple rope grooves 14, and the two ends of each sensitive H-shaped component 12 extend to the corresponding two detection ports 15.

[0042] The scheme has a simple structure, and the staggered distribution of multiple sensitive components H-type 12 is reasonable, so as to detect different types of damage to the steel wire rope under inspection, and avoid mutual interference between two adjacent sensitive components H-type 12, thus achieving higher detection accuracy.

[0043] Based on the above scheme, the distribution of multiple sensitive components H-type 12 is as follows: the first sensitive component H-type 12 is distributed at one end of the back side of the first rope groove 14, the second sensitive component H-type 12 is distributed at the other end of the back side of the second rope groove 14, the third sensitive component H-type 12 is distributed at one end of the back side of the third rope groove 14, and so on.

[0044] Alternatively, the aforementioned multiple sensitive H-type 12 components can be arranged side by side on the back side of multiple rope grooves 14. However, in this scheme, two adjacent sensitive H-type 12 components will interfere with each other, affecting the accuracy of detection.

[0045] Example 3 Based on the above embodiments, in this embodiment, multiple sensitive O-type 13 components are arranged side by side or staggered in sequence in the detection port 15 area on the back side of multiple rope grooves 14.

[0046] The scheme has a simple structure and the multiple sensitive components (O-type 13) are distributed in a reasonable manner to detect different types of damage to the steel wire rope under inspection.

[0047] Based on the above scheme, multiple sensitive components O-type 13 can be distributed at the center of the back side of multiple rope grooves 14.

[0048] Alternatively, multiple sensitive components O-type 13 are respectively bonded and distributed with multiple sensitive components H-type 12.

[0049] Example 4 Based on the above embodiments, in this embodiment, the sensitive component H-type 12 and the sensitive component O-type 13 are respectively adopted as customized resistance type sensors.

[0050] The solution has a simple structure, with customized resistance-sensitive components, H-type and O-type sensors, evenly and reasonably arranged to simultaneously detect wire breakage and wear damage in the wire rope, resulting in more accurate detection.

[0051] In addition, the sensitive components H-type 12 and O-type 13 are used to detect broken wires and wear of the wire rope under test through software algorithm functions, so as to detect the types of damage such as broken wires and wear of the wire rope at the same time, and the measurement is more accurate.

[0052] Preferably, in this embodiment, the sensitive component H-type 12 and the sensitive component O-type 13 are respectively improved by combining existing technologies. They are used to detect broken wires and wear of the steel wire rope under test through software algorithm functions, and their specific structures and principles will not be described in detail here.

[0053] Example 5 Based on the above embodiments, such as Figures 6 to 16 As shown, this embodiment also provides a small-pitch multi-rope parallel steel wire rope detection probe, including an upper magnetizer assembly 2, a lower magnetizer assembly 3, and a magnetic sensitive element assembly as described above. The upper magnetizer assembly 2 and the lower magnetizer assembly 3 are distributed opposite to each other on both sides of the two bases 11.

[0054] Magnetic flux leakage testing is a process in which an upper magnetizer assembly 2 and a lower magnetizer assembly 3 generate a magnetic field during the inspection process. A magnetic flux leakage field is generated at the defect of the wire rope, and the magnetic flux leakage signal is detected by two magnetic sensing elements 1 to realize the detection of defects in the wire rope. In addition, this embodiment provides a small-pitch multi-rope parallel steel wire rope detection probe. The probe has a compact structure and reasonable design, and can realize intelligent detection of damage types such as broken wires and wear in multi-rope parallel steel wire ropes. The detection is convenient, efficient and accurate.

[0055] It should be noted that the upper magnetizer assembly 2 and the lower magnetizer assembly 3 mentioned above adopt existing technologies, and their specific structures and principles will not be elaborated here.

[0056] Based on the above scheme, the working principle of this embodiment is as follows: First, multiple steel wire ropes to be tested are passed through multiple testing channels and multiple passing channels respectively; Then, the upper magnetizer assembly 2 and the lower magnetizer assembly 3 work to generate a magnetic field, and a leakage magnetic field is generated at the defect of the wire rope. Meanwhile, the leakage magnetic signal is detected by two magnetic sensitive elements 1, and multiple sensitive components H-type 12 in the two magnetic sensitive elements 1 are used to detect whether there are broken wires in the wire rope. Multiple sensitive components O-type 13 are used to detect whether there is wear or other damage in the wire rope. This effectively detects the defects in the wire rope. The multiple sensitive components H-type 12 and multiple sensitive components O-type 13 send the corresponding signals to the control module 8. In addition, the aforementioned control module 8 receives the corresponding signals and analyzes the specific location of the wire rope to determine the type of damage such as broken wires or wear, so that maintenance personnel can handle it in a timely manner.

[0057] Example 6 Based on embodiment 5, this embodiment also includes two pairs of cable trays 4, which are distributed opposite to each other on both sides of the two seats 11, and each pair of cable trays 4 is distributed opposite to each other; the opposite sides of the two pairs of cable trays 4 are evenly spaced and distributed with multiple pairs of support rope grooves 41, which form multiple through channels, and the multiple through channels are respectively connected to multiple detection channels.

[0058] The scheme has a simple structure and reasonable design. It uses two pairs of cable trays and four pairs of multiple rows of steel wire ropes for support, which facilitates the inspection of the steel wire ropes.

[0059] Preferably, in this embodiment, each of the above-mentioned cable trays 4 is preferably a long strip-shaped rectangular block structure, which is distributed parallel to the tray body 11.

[0060] In addition, the length of the aforementioned cable connector 4 is the same as the length of the connector body 11.

[0061] Preferably, in this embodiment, the plurality of support rope grooves 41 are each preferably semi-circular grooves, the shape of which matches the shape of the wire rope.

[0062] During actual testing, the seat 11 and cable tray 4 can be replaced according to the specifications of the wire rope to be tested, so as to meet the testing needs of wire ropes of different specifications, making the testing convenient.

[0063] Example 7 Based on Embodiment 6, in this embodiment, the diameter of the support rope groove 41 is smaller than the diameter of the rope groove 14.

[0064] The scheme has a simple structure and a reasonable design. On the one hand, the diameter of the support rope groove 41 is smaller than the diameter of the rope groove 14, which can prevent the wire rope from contacting the rope groove 14, protect the rope groove, and avoid wear. On the other hand, the smaller diameter of the support groove 41 compared to the diameter of the groove 14 makes it easier to detect damage types such as broken wires or wear on the wire rope, making the detection more convenient.

[0065] Alternatively, the diameter of the aforementioned support rope groove 41 can be equal to the diameter of the rope groove 14. However, in this case, the wire rope will directly contact the groove wall of the rope groove 14, which will wear down the groove wall of the rope groove 14 and affect the detection effect.

[0066] Alternatively, if only one pair of cable trays 4 are provided, this solution cannot guarantee the stability of the wire rope installation, and the wire rope is also prone to wear on the rope groove 14.

[0067] Example 8 Based on any one of Embodiments 5 to 7, this embodiment further includes an upper shell 5 and a lower shell 6, the upper shell 5 and the lower shell 6 being distributed opposite to each other, with openings on both sides; the upper magnetizer assembly 2, the lower magnetizer assembly 3 and the two seats 11 are respectively distributed in the area enclosed by the upper shell 5 and the lower shell 6.

[0068] The scheme has a simple structure and reasonable design. It utilizes the upper shell 5 and the lower shell 6 to form an assembly space for assembling the upper magnetizer assembly 2, the lower magnetizer assembly 3, and the two magnetic sensitive elements 1. The assembly is convenient and more neat and beautiful.

[0069] Preferably, in this embodiment, the upper shell 5 and the lower shell 6 are both rectangular shells and have the same size.

[0070] Preferably, in this embodiment, the assembly method between the upper housing 5 and the lower housing 6 is as follows: Option 1: The upper housing 5 and the lower housing 6 are directly connected by bolts. In this option, the upper housing 5 and the lower housing 6 have multiple pairs of through holes that mate with multiple bolts. This option is more complicated to disassemble and assemble, and is time-consuming and labor-intensive.

[0071] Option 2: One end of the upper housing 5 is rotatably connected to one end of the lower housing 6, and the other end can be rotatably attached to the other end of the lower housing 6 and detachably connected.

[0072] In addition, one end of the upper housing 5 is rotatably connected to one end of the lower housing 6 via multiple hinges, such as two hinges.

[0073] Furthermore, the other end of the upper housing 5 and the other end of the lower housing 6 are detachably connected by multiple latches 9. Specifically, two latch seats are fixedly installed on the other end of the upper housing 5, and two buckles are rotatably installed on each of the two latch seats; two buckle plates are fixedly installed on the other end of the lower housing 6. When the other end of the upper housing 5 is rotated to fit against the other end of the lower housing 6, the two buckles can respectively fasten the two buckle plates. This design is reasonable, easy to operate, facilitates the assembly of various components, and facilitates the laying of steel wire ropes.

[0074] Alternatively, the other end of the upper housing 5 and the other end of the lower housing 6 can be detachably connected by bolts, but this solution is not as convenient to operate as the one described above.

[0075] Preferably, in this embodiment, the upper housing 5 and the lower housing 6 are respectively provided with through openings at both ends, which is a reasonable design and facilitates the assembly of the hinges and buckles 9.

[0076] Preferably, in this embodiment, the upper housing 5 and the lower housing 6 are respectively designed with guide positioning pins and positioning holes to ensure the precision and accuracy of the connection between the upper and lower housings, and to prevent erroneous damage signals and interference waveforms from occurring during the inspection of the steel wire rope due to misalignment. The design is reasonable.

[0077] Preferably, in this embodiment, a handle 10 is fixedly installed on the top of the upper housing 5, which is reasonably designed and convenient for testing personnel to operate.

[0078] In addition, the handle 10 is preferably U-shaped, with its open end fixedly connected to the upper housing 5 on both sides.

[0079] Preferably, in this embodiment, shock-absorbing support pads are fixedly installed at the four corners of the bottom of the lower housing 6.

[0080] In addition, the aforementioned shock-absorbing support pads are preferably frustum-shaped structures.

[0081] Example 9 Based on Embodiment 8, this embodiment also includes an encoder 7, which is installed on the upper housing 5 or the lower housing 6 and is used to locate the flaw detection area of ​​the steel wire rope to be inspected.

[0082] The scheme has a simple structure and reasonable design. During the wire rope inspection process, the encoder 7 is used to locate the wire rope being inspected in order to determine the location of the damage type such as broken wires or wear, which greatly improves the accuracy.

[0083] Preferably, in this embodiment, the encoder 7 is preferably distributed on the upper housing 5 and is used to locate the flaw detection area of ​​the wire rope to be tested. During testing, it is located above the wire rope row.

[0084] Alternatively, the encoder 7 described above can also be mounted on the lower housing 6.

[0085] Preferably, in this embodiment, the encoder 7 can be disposed at any end or in the middle of the upper housing 5.

[0086] In addition, the number of encoders 7 can be one or more. When multiple encoders 7 are used, they are arranged side by side on one side of the upper housing 5.

[0087] Based on the above scheme, the principle of the encoder 7 positioning steel wire rope is as follows: The encoder 7 detects the set position of the wire rope, and then uses the upper magnetizer assembly 2 and the lower magnetizer assembly 3 to generate a magnetic field. A leakage magnetic field is generated at the defect of the wire rope. At the same time, the leakage magnetic signal is detected by two magnetic sensitive elements 1 to realize the detection of wire rope defects. Based on the distance of the detected wire rope damage type such as broken wire or wear from the position of the wire rope located by the encoder 7, the specific location of the wire rope damage type such as broken wire or wear can be determined.

[0088] It should be noted that the encoder 7 mentioned above uses existing technology, and its specific structure and principle will not be described in detail here.

[0089] The detection principle of this embodiment is as follows: First, multiple steel wire ropes to be tested are passed through multiple testing channels and multiple passing channels respectively; Then, the upper magnetizer assembly 2 and the lower magnetizer assembly 3 work to generate a magnetic field, and a leakage magnetic field is generated at the defect of the wire rope. Simultaneously, leakage magnetic signals are detected using two magnetic sensitive elements 1. Multiple sensitive components H-type 12 in the two magnetic sensitive elements 1 are used to detect whether there are broken wires in the wire rope, and multiple sensitive components O-type 13 are used to detect whether there is wear or other damage in the wire rope. This effectively detects defects in the wire rope. The multiple sensitive components H-type 12 and multiple sensitive components O-type 13 send corresponding signals to the control module 8. The control module 8 receives the corresponding signals and analyzes them based on the judgment. During this process, the encoder 7 detects the set position of the wire rope, and then uses the upper magnetizer assembly 2 and the lower magnetizer assembly 3 to generate a magnetic field. The defect of the wire rope generates a leakage magnetic field, and at the same time, the leakage magnetic signal is detected by two magnetic sensitive elements 1 to realize the detection of wire rope defects. Based on the distance of the detected wire rope damage type such as broken wire or wear from the position of the wire rope located by the encoder 7, the specific location of the wire rope damage type such as broken wire or wear can be determined.

[0090] Example 10 Based on any one of Examples 5 to 9, such as Figure 17 As shown, this embodiment also provides a small-pitch multi-rope parallel steel wire rope intelligent detection system, including a control module 8 and a small-pitch multi-rope parallel steel wire rope detection probe as described above. The upper magnetizer assembly 2, the lower magnetizer assembly 3, and the multiple sensitive components H-type 12 and multiple sensitive components O-type 13 are respectively connected to the control module 8 for communication.

[0091] Based on the above scheme, the control module 8 adopts existing technology. Its function is to receive the corresponding signals sent by each component, make judgments and analyses, and control the operation of the corresponding components according to the analysis results, so as to realize the intelligence and automation of the entire detection process, resulting in higher detection efficiency and higher accuracy.

[0092] This embodiment provides an intelligent detection system for parallel multi-rope steel wire ropes with small spacing. The system has a compact structure and reasonable design, and can realize intelligent detection of damage types such as broken wires and wear in parallel multi-rope steel wire ropes. The detection is convenient, efficient, and accurate.

[0093] This invention provides a magnetic sensing element assembly, a small-pitch multi-rope parallel steel wire rope detection probe and system, the specific detection principle of which is as follows: First, multiple steel wire ropes to be tested are passed through multiple testing channels and multiple passing channels respectively; Then, the upper magnetizer assembly 2 and the lower magnetizer assembly 3 work to generate a magnetic field, and a leakage magnetic field is generated at the defect of the wire rope. Simultaneously, leakage magnetic signals are detected using two magnetic sensitive elements 1. Multiple sensitive components H-type 12 in the two magnetic sensitive elements 1 are used to detect whether there are broken wires in the wire rope, and multiple sensitive components O-type 13 are used to detect whether there is wear or other damage in the wire rope. This effectively detects defects in the wire rope. The multiple sensitive components H-type 12 and multiple sensitive components O-type 13 send corresponding signals to the control module 8. The control module 8 receives the corresponding signals and analyzes them based on the judgment. During this process, the encoder 7 detects the set position of the wire rope, and then uses the upper magnetizer assembly 2 and the lower magnetizer assembly 3 to generate a magnetic field. The defect of the wire rope generates a leakage magnetic field, and at the same time, the leakage magnetic signal is detected by two magnetic sensitive elements 1 to realize the detection of wire rope defects. Based on the distance of the detected wire rope damage type such as broken wire or wear from the position of the wire rope located by the encoder 7, the specific location of the wire rope damage type such as broken wire or wear can be determined.
