Description

Technical Field

[0001] This utility model belongs to the field of wire rope damage detection technology, and in particular relates to a wire rope damage detection probe array structure. Background Technology

[0002] Steel wire ropes play a vital role in many fields today. Their safety directly determines the operational safety of the entire system and the safety of people's lives and property. However, due to the complex structure of steel wire ropes and their long-term exposure to harsh environments, they are highly susceptible to various damages such as wear, corrosion, fatigue, and broken wires. These damages gradually weaken the load-bearing capacity and structural integrity of the steel wire rope, creating huge safety hazards. Once a break occurs, it will lead to catastrophic consequences.

[0003] Therefore, it is necessary to detect wire rope damage. Nowadays, some combine wire rope damage detectors with wire rope crawling robots. The crawling robot drives the wire rope damage detector to move, which facilitates comprehensive detection of long-span fixed wire ropes. In the wire rope damage detector, the distribution of Hall elements inside is very important for the detection of wire rope damage.

[0004] Chinese patent CN222965160U discloses an autonomous crawling robot for steel wire rope equipped with a non-destructive testing device. The patent states that it "includes an autonomous crawling robot, a flaw detector loading device, and a flaw detector. The flaw detector loading device is connected to the front end of the autonomous crawling robot in its running direction, and the flaw detector is connected to the rear end of the autonomous crawling robot in its running direction. The autonomous crawling robot is clamped onto a steel wire rope. This utility model provides an autonomous crawling robot for steel wire rope equipped with a non-destructive testing device."

[0005] However, existing technologies are susceptible to temperature effects. For example, the low temperature in high-altitude environments can cause errors in the Hall element detection, which in turn affects the accuracy of wire rope damage detection. At the same time, the fixed position of the Hall element means that its distance from wire ropes of different diameters will also vary, which will affect the accuracy of damage detection for wire ropes of different diameters, making it inconvenient to use. Therefore, it is necessary to design a wire rope damage detection probe array structure. Utility Model Content

[0006] This invention provides a probe array structure for detecting wire rope damage, aiming to solve the problem that some probe array structures currently in use are inconvenient to compensate for temperature differences.

[0007] This utility model is implemented as follows: a wire rope damage detection probe array structure includes a flaw detector body; a cavity formed inside the flaw detector body, the inner wall of the cavity having reserved slots at equal angles that penetrate the outside of the flaw detector body; an electric push rod fixedly connected at equal angles to the inner wall of the cavity, the output end of the electric push rod being fixedly connected to a mounting plate, a distance sensor being fixedly connected to one side of the mounting plate, and a Hall element being provided on the other side of the mounting plate; heating wires symmetrically fixedly connected inside the cavity, and a temperature sensor being fixedly connected to one side of the inner wall of the cavity.

[0008] Preferably, the heating wire is arc-shaped and symmetrically distributed about the vertical central axis of the cavity.

[0009] Preferably, a shielding cover is fixedly connected to the inner wall of the cavity, and the shielding cover is semi-circular in shape.

[0010] Preferably, the area of ​​the reserved groove cross-section is larger than the area of ​​the mounting plate cross-section, and one side of the inner wall of the reserved groove is semi-circular.

[0011] Preferably, a sliding rod is fixedly connected to the inner wall of the cavity on one side of the electric push rod, and a sliding plate is fixedly connected to one side of the mounting plate.

[0012] Preferably, one end of the sliding plate forms a sliding structure with the surface of the sliding rod, and the shape of the sliding plate is an inverted L-shape.

[0013] Preferably, a slot is provided on one side of the mounting plate, and a bolt hole is provided on one side of the inner wall of the slot. A locking block is fixedly connected to one end of the Hall element, and a fixing groove is provided on one side of the locking block. A fixing bolt that is threadedly connected to the inner wall of the fixing groove is movably connected to the fixing bolt hole.

[0014] Preferably, the card block and the inside of the card slot form a sliding engagement structure, and the card slot and the card block are convex in shape.

[0015] Preferably, an elastic sheet is fixedly connected to the inner wall of the fixing groove at equal angles, and one side of the elastic sheet is inclined.

[0016] Compared with related technologies, the wire rope damage detection probe array structure provided by this utility model has the following beneficial effects: 1. The electric push rod is activated according to the diameter of the wire rope, causing the mounting plate to slide smoothly and move the Hall element towards the wire rope. At the same time, the distance sensor can detect the distance between the Hall element and the wire rope diameter in real time, ensuring the optimal detection distance between the Hall element and the wire rope. The Hall elements are evenly distributed around the circumference of the wire rope, facilitating comprehensive and blind-angle damage detection. Furthermore, the temperature sensor detects the temperature inside the cavity. When the detected temperature is too low, the heating wire can be activated to heat the inside of the cavity, effectively preventing the detection accuracy of the Hall element from being affected by low temperature. This allows the device to perform more accurate detection of damage to long-distance fixed wire ropes at high altitudes, improving its practicality.

[0017] 2. By utilizing the sliding engagement between the card block and the inside of the card slot, and the thread engagement between the fixing bolt and the inside of the bolt hole, the Hall element and the mounting plate can be quickly disassembled and assembled, realizing the modular installation of the Hall element, which facilitates the disassembly and maintenance of the Hall element.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] Example 1 A preferred embodiment of the wire rope damage detection probe array structure provided by this utility model is, for example... Figures 1 to 6 As shown: A wire rope damage detection probe array structure includes a flaw detector body 1; a cavity 4 opened inside the flaw detector body 1, with reserved slots 3 through the outside of the flaw detector body 1 opened at equal angles on the inner wall of the cavity 4; electric push rods 5 fixedly connected at equal angles to the inner wall of the cavity 4, with a mounting plate 8 fixedly connected to the output end of the electric push rods 5, a distance sensor 10 fixedly connected to one side of the mounting plate 8, and a Hall element 9 provided on the other side of the mounting plate 8; heating wires 2 symmetrically fixedly connected inside the cavity 4, and a temperature sensor 7 fixedly connected to one side of the inner wall of the cavity 4.

[0023] It should be noted that some existing wire rope damage detection probe array structures still have certain shortcomings in actual use. They are easily affected by temperature. For example, the low temperature in high-altitude environments can easily cause detection errors in the Hall element 9, which in turn affects the accuracy of wire rope damage detection. At the same time, the fixed position of the Hall element 9 means that its distance from wire ropes of different diameters is also different, which will also affect the accuracy of damage detection for wire ropes of different diameters, making it inconvenient to use.

[0024] In a further preferred embodiment of this utility model, the heating wire 2 is arc-shaped and is symmetrically distributed about the vertical central axis of the cavity 4.

[0025] In this embodiment, symmetrically distributed and arc-shaped heating wires 2 are used to facilitate better heating and heat preservation inside the cavity 4.

[0026] In a further preferred embodiment of this utility model, a shielding cover 6 is fixedly connected to the inner wall of the cavity 4, and the shielding cover 6 is semi-circular in shape.

[0027] In this embodiment, the use of a semi-circular shield 6 can reduce the external electromagnetic influence on the Hall element 9.

[0028] In a further preferred embodiment of this utility model, the cross-sectional area of ​​the reserved groove 3 is larger than the cross-sectional area of ​​the mounting plate 8, and one side of the inner wall of the reserved groove 3 is semi-circular.

[0029] In this embodiment, a large-area reserved slot 3 is used so that the mounting plate 8 and the Hall element 9 can extend out of the cavity 4 from the reserved slot 3.

[0030] In a further preferred embodiment of this utility model, a slide rod 12 is fixedly connected to the inner wall of the cavity 4 on one side of the electric push rod 5, and a slide plate 13 is fixedly connected to one side of the mounting plate 8.

[0031] In a further preferred embodiment of the present invention, a sliding structure is formed between one end of the sliding plate 13 and the surface of the sliding rod 12, and the shape of the sliding plate 13 is an inverted L-shape.

[0032] In this embodiment, the smoothness of the mounting plate 8 sliding up and down is improved by utilizing the sliding of the sliding plate 13 and the sliding rod 12.

[0033] Example 2 Based on Embodiment 1, a preferred embodiment of the wire rope damage detection probe array structure provided by this utility model is as follows: Figures 1 to 6 As shown: A slot 14 is provided on one side of the mounting plate 8, and a bolt hole 11 is provided on one side of the inner wall of the slot 14. A block 15 is fixedly connected to one end of the Hall element 9. A fixing groove 17 is provided on one side of the block 15. A fixing bolt 16 that is threadedly connected to the inner wall of the fixing groove 17 is movably connected to the bolt hole 11.

[0034] In this embodiment, after loosening the fixing bolt 16 with a screwdriver or other tools until it is completely disengaged from the bolt hole 11, the Hall element 9 can be pushed, causing the locking block 15 to slide out of the slot 14, making it easy to disassemble and maintain the Hall element 9. During installation, the locking block 15 is slid into the slot 14, and the fixing bolt 16 is tightened into the bolt hole 11, realizing the sliding installation of the locking block 15 and the slot 14, thereby enabling the quick installation and removal of the Hall element 9.

[0035] In a further preferred embodiment of the present invention, a sliding engagement structure is formed between the inside of the card block 15 and the card groove 14, and the card groove 14 and the card block 15 are convex in shape.

[0036] In this embodiment, the convex locking block 15 and the locking groove 14 are used to improve the stability of the sliding installation of the Hall element 9.

[0037] In a further preferred embodiment of the present invention, an elastic sheet 18 is fixedly connected to the inner wall of the fixing groove 17 at equal angles, and one side of the elastic sheet 18 is inclined.

[0038] In this embodiment, the use of the inclined elastic sheet 18 can improve the anti-slip fastness of the fixing bolt 16 nut and the inner wall of the fixing groove 17, thereby effectively preventing the fixing bolt 16 from becoming loose and affecting the stability of the sliding installation of the locking block 15 and the locking groove 14.

[0039] In summary, firstly, the flaw detector body 1 is connected and fixed to the wire rope crawling robot. Then, the crawling robot is installed and fixed on the wire rope. At the same time, the electric push rod 5 is activated according to the diameter of the wire rope. The sliding plate 13 slides on the surface of the sliding rod 12, so that the mounting plate 8 slides smoothly and drives the Hall element 9 to move towards the wire rope. Meanwhile, the distance sensor 10 can detect the distance between the Hall element 9 and the diameter of the wire rope in real time, ensuring the optimal detection distance between the Hall element 9 and the wire rope. At the same time, the Hall elements 9 are evenly distributed at the circumference of the wire rope, which facilitates comprehensive and blind-angle damage detection of the wire rope. When in environments such as high altitudes, where the external temperature is low, the temperature sensor 7 detects the temperature inside the cavity 4. When the detected temperature is too low, the heating wire 2 can be activated to heat the inside of the cavity 4, thereby effectively avoiding the impact of low temperature on the detection accuracy of the Hall element 9. Simultaneously, the Hall element 9 and mounting plate 8 can be extended to the outside of the reserved slot 3 by the electric push rod 5. After the fixing bolt 16 is loosened by a screwdriver or other tools until it is completely disengaged from the bolt hole 11, the Hall element 9 can be pushed so that the locking block 15 slides out of the slot 14, making it easy to disassemble the Hall element 9 for maintenance. During installation, the locking block 15 is slid into the slot 14, and the fixing bolt 16 is tightened into the bolt hole 11 to achieve sliding installation of the locking block 15 and the slot 14, thereby enabling quick installation and removal of the Hall element 9.
