Description

Technical Field

[0001] The present invention relates to the technical field of cable detection, and in particular to a cable anti-aging detection device. Background Art

[0002] After a period of time in a high-temperature environment, the outer insulation layer of the cable will become hard and the cable's anti-bending effect will also decrease. In order to study the relevant performance of the cable in a high-temperature environment, it is necessary to test the cable's anti-aging performance. The cable aging test is to place the cable in a harsh environment such as high temperature for a period of time, and then test the cable's anti-bending, anti-compression, anti-torsion and other properties to simulate the performance of the cable after aging.

[0003] A Chinese patent document with authorization announcement number CN114813311B discloses a coaxial cable detection device, comprising a base, a mounting bracket mounted on the top of the base, the base being in the shape of a hollow shell, a first motor mounted inside the base, a first active rod mounted on the power output end of the first motor, and a first driven rod mounted inside the base and on the top of the first motor. The present invention improves a commonly used detection device so that when the device is in use, a clamp is used to fix the cable body. When performing a torque resistance test, the first motor drives the two sets of sleeves to rotate in opposite directions, driving the two ends of the cable body to rotate in opposite directions, thereby testing the torque resistance of the cable body. When testing the tensile strength and frequent bending ability of the cable body, the second motor drives the extrusion rod to descend, testing the tensile strength of the cable body while also testing the frequent bending performance of the cable body.

[0004] In the above technical solution, when testing the cables, the cables are directly tested through each testing component, and the data only represents the various data of one cable. If different cables are re-clamped and tested, and different groups of cables are tested separately, the operation is also more troublesome. The variables of each group of cables are difficult to control, such as the detection length and torsion angle of the cables. When collecting data after cable aging, it is difficult to form effective comparative data for research. Summary of the Invention

[0005] The present invention provides a cable anti-aging detection device, which aims to solve the problem in the related art that it is difficult to form comparative data for studying the detection performance of cables after aging.

[0006] A cable anti-aging detection device includes an installation component and a detection component, wherein the installation component includes at least two winding wheels with gradually decreasing diameters arranged from left to right, and adjacent winding wheels are slidably connected in the left-right direction. A fixing piece for fixing one end of a cable is installed at the right end of the winding wheel, and each winding wheel is threadedly connected to a rotating ring, and the pitch of the thread is the same as the diameter of the cable. A clamping piece for clamping the cable is installed on the rotating ring, and the clamping piece includes a fixed end and a movable end. When the movable end clamps the cable, the clamping piece abuts against the rotating ring. When the movable end is separated from the cable, the clamping piece slides along the circumference of the rotating ring, and the fixed end is used to press the cable.

[0007] The detection assembly is installed at the fixed end of the clamp and is used to detect cracks on the cable surface. The left winding wheel is equipped with a drive device for driving it to rotate around its own axis. The outer periphery of each winding wheel is equipped with a pressure detector for testing the compressive strength of the cable. A torque tester is also installed on one side of each winding wheel for stretching the cable and performing torque testing:

[0008] The effect is that: by setting up multiple groups of winding wheels, cables of the same length are wound on winding wheels of different diameters, the cables are wound on the cables by rotating the rotating wheels, and one end of the cables is fixed by a fixing part. The bending degrees of the cables wound on different winding wheels are different. The smaller the diameter, the more cable turns the winding wheel has. After the cable is wound, the other end of the cable is fixed by the fixed end of the clamping part. When the cable is wound, the detection component is driven by the movement of the clamping part to detect the surface of the cable after bending, and the detection results are compared by setting up multiple groups of cables; the hardness of the cable after aging is tested by a pressure tester, and the detection interval is fixed by rotating the cable to make the test results more stable. When the test is completed, the cable is stretched by pulling the torque tester. The number of cable turns on different winding wheels is different, and the torque when the cable is straightened is different. The torsional strength of the cable is tested by comparing multiple groups of data.

[0009] Preferably, the fixing member includes a mounting plate and a screw, the screw is threadedly connected to the fixing plate, and the fixing plate is fixedly arranged on the winding wheel; when fixing the cable, one end of the cable is placed between the mounting plate and the screw, and by rotating the screw, the bottom of the screw is in close contact with one end of the cable, thereby achieving firm fixation of the cable.

[0010] Preferably, the movable end of the clamping member includes a fixed plate and a sliding plate, the fixed plate being fixedly mounted on the annular slider, the sliding plate being elastically slidably connected to the annular slider in the left-right direction, the sliding plate including a left plate and a right plate, the left plate being located within the annular groove, a clamping cavity for clamping the cable being formed between the right plate and the fixed plate, and a tension spring being installed between the right plate and the fixed plate; when the leftmost winding wheel is rotated, since adjacent winding wheels do not rotate relative to each other in the circumferential direction, all winding wheels rotate synchronously when the leftmost winding wheel rotates. When the clamping member clamps the cable, the clamping member abuts against the rotating ring, which spirally rotates on the winding wheel and moves to the left. Because the pitch of the thread is the same as the cable diameter, the cable is wound around the reel once with each rotation of the rotating ring, ultimately forming a spiral around the reel. To ensure comparability of the test results of the present invention, the cable lengths wound on all reels must be the same. However, due to the different diameters of the reels, the number of turns on each reel varies, with the leftmost reel being the largest and having the fewest turns of cable. When the cable on the leftmost reel is wound, the movable end of the clamping member no longer abuts the cable. The clamping member slides along the circumference of the rotating ring, no longer driving the rotating ring. The reels continue to rotate until the movable ends of all clamping members are disengaged from the reel.

[0011] Preferably, the fixed end of the clamping member is a pressing plate, which is fixedly arranged on the annular slider, and the gap between the pressing plate and the winding wheel is smaller than the diameter of the cable; when the movable end of the clamping member is separated from the cable, the pressing plate will press the other end of the cable onto the winding wheel, thereby preventing the cable from falling off the winding wheel.

[0012] Preferably, between the two adjacent winding wheels, a limit rod is fixedly provided on the winding wheel on the left, and a limit groove is provided on the winding wheel on the right, and the limit rod is slidably provided in the limit groove; when the cable is gradually wound in a spiral shape on the winding wheel, the winding wheel on the right gradually slides to the right.

[0013] Preferably, a mounting groove is provided at the bottom of the winding wheel, and all the clamping members are slidably arranged in the mounting groove; when the cable is gradually spirally wound around the winding wheel, the winding wheel on the right side gradually moves to the right.

[0014] Preferably, the driving device is a rotary motor, and the leftmost winding wheel is arranged with the output shaft of the rotary motor; the winding wheel is driven to rotate by the rotation of the motor, so that the rotating wheel moves leftward along the spiral path on the winding wheel.

[0015] Preferably, the detection assembly includes a piezoelectric sensor and an elastic detection head. The elastic detection head includes a sliding rod and a spring. The sliding rod is mounted on the fixed end of the clamping member and slides radially along the reel. The spring is mounted between the sliding rod and the fixed end of the clamping member. The end of the sliding rod closest to the reel abuts the cable and has a tapered surface. When the rotating ring rotates, the reel and the clamping member move leftward along a spiral path, thereby winding the cable onto the reel. The sliding rod closely follows the movement of the clamping assembly and extends along the cable. When a gap forms in the cable due to bending, one end of the sliding rod slightly adjusts downward, causing the pressure value of the piezoelectric sensor to change. By counting the number of changes in the piezoelectric sensor pressure value, the number of cracks in the cable can be calculated; by analyzing the amplitude of the change in the piezoelectric sensor pressure value, the size of the crack in the cable can be determined. This data can be used to further analyze the condition of the cable after aging. When the cable is wound on a reel under different storage conditions, the curvature of the bend varies. By comparing this data, the bending resistance of the cable after aging can be further explored.

[0016] Preferably, the pressure detector includes a mounting platform, a motorized telescopic rod, a puncture needle, and a pressure sensor. A drive motor rotates the reel, and each cable rotation results in a puncture, ensuring a consistent puncture distance. This allows for comparison of puncture forces on the same cable, avoiding inaccuracies in single puncture data. By comparing puncture data from cables with varying curvatures, the variation in puncture force required under different curvatures can be studied, further exploring changes in cable hardness as the cable ages.

[0017] Preferably, there are three winding wheels, and the radius sizes of the three winding wheels from left to right are R1, R2, and R3 respectively. The radius size of the cable is R1, (R1+R):(R2+R):(R3+R)=3:2:1. When cables of the same length are wound on the winding wheels, the ratio of the number of cable turns wound on the three winding wheels from left to right is 2:3:6.

[0018] By adopting the above technical solution, the beneficial effects of the present invention are:

[0019] 1. When testing the cable's anti-aging performance, first wind the aged cable onto reels of different diameters. Use the fixings on the reel to fix one end of the cable, and clamp the cable with the movable end of the clamp. At this time, the clamp and the rotating ring abut against each other and remain relatively stationary. Rotate the reel, and the rotating ring moves spirally to the left on the reel to wind the cable onto the reel. When the movable end of the clamp disengages from the cable and the reel rotates, the rotating ring and the reel remain relatively stationary. At this time, press the cable with the fixed end of the clamp to prevent it from falling off the reel. Continue to rotate the reel until all cables are wound onto reels of different diameters. During the winding process, the clamp slides relative to the cable surface, and the cable surface is inspected by the detection component on the clamp. When cables of the same length are wound onto reels of different diameters, their anti-bending performance is determined by counting the number of cracks on the cable, and the research is conducted by comparing multiple sets of data.

[0020] 2. The pressure tester can accurately test the cable's compressive strength. When the reel rotates, the instrument can perform synchronous compressive tests on the same intervals on multiple groups of cables, thereby ensuring the accuracy of data collection. This effectively avoids the problem of insufficient comparability of collected data due to differences in the spacing between different groups of cables.

[0021] 3. Use a torque tester to straighten the cable. Because the number of turns of cable wound on reels of different diameters varies, the number of twists each cable undergoes after straightening also varies. By comparing the force required for different twisting times, the torsional resistance of the cable after aging can be compared. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figures 1-6 As shown, a cable anti-aging detection device includes an installation component 1 and a detection component 2. The installation component 1 includes a winding wheel 11, a fixing member 6, a clamping member 7 and a pressure detector 4. When testing the cable, the cable is wound on the winding wheel 11. Before winding, one end of the cable is fixed on the winding wheel 11. After the cable is wound, the cable is clamped by the clamping member 7. When the surface of the cable is bent is detected, the detection component 2 moves with the clamping member 7 to completely detect the outer surface of the entire cable, and the pressure resistance of the cable is detected by the pressure detector 4.

[0032] There are at least two winding wheels 11. In order to explain the detection of the cable in detail, the present invention is described with three winding wheels 11. The three winding wheels 11 are arranged in sequence from left to right. The sizes of the three winding wheels 11 gradually decrease from left to right. The winding wheel 11 on the right side is slid left and right inside the adjacent left winding wheel 11. The fixing member 6 is installed at the right end of the winding wheel 11. The cable is fixed by the fixing member 6. Each winding wheel 11 is threadedly connected to the rotating ring 12. The pitch of the thread is the same as the diameter of the cable. The rotating ring 12 is equipped with a cable clamp for clamping the cable. The clamping member 7 includes a fixed end 72 and a movable end 71, and the detection component 2 is installed on the clamping member 7; when testing the bending resistance of the cable, the cable is wound on the winding wheel 11, and the number of cracks on the cable surface is used to constant the anti-aging performance of the cable. After fixing one end of the cable with the fixing member 6, the cable is clamped by the clamping member 7, and the winding wheel 11 on the far left is rotated. Since the adjacent winding wheels 11 do not rotate relative to each other in the circumferential direction, when the winding wheel 11 on the far left is rotated, all the winding wheels 11 rotate synchronously. When the clamping member 7 clamps the cable The clamping member 7 abuts against the rotating ring 12, and the rotating ring 12 spirally rotates on the winding wheel 11 and moves to the left. Since the pitch of the thread is the same as the diameter of the cable, the cable is wound around the winding wheel 11 once for each rotation of the rotating ring 12, and finally the cable is wound around the winding wheel 11 in a spiral shape. In order to make the test results of the present invention comparable, the length of the cable wound on all the winding wheels 11 is the same. Due to the different diameters of the winding wheels 11, the number of turns wound on each winding wheel 11 is different. The leftmost winding wheel 11 has the largest size and the number of turns of the cable wound on it is At the very least, when the cable on the leftmost winding wheel 11 is wound, the movable end 71 of the clamping member 7 no longer abuts the cable. At this time, the clamping member 7 slides along the circumference of the rotating ring 12 and no longer drives the rotating ring 12 to rotate, and the winding wheel 11 continues to rotate until the movable ends 71 ​​of all the clamping members 7 are detached from the winding wheel 11. The fixed end 72 of the clamping member 7 moves to the other end of the cable and fixes the cable to prevent the cable from detaching from the winding wheel 11. The detection component 2 moves with the fixed end 72 of the clamping member 7 and detects cracks on the cable after bending.

[0033] There are three winding wheels 11, and the radius sizes of the three winding wheels 11 from left to right are R1, R2, and R3 respectively. The radius size of the cable is R, (R1+R):(R2+R):(R3+R)=3:2:1. When cables of the same length are wound on the winding wheels 11, the ratio of the number of cable turns wound on the three winding wheels 11 from left to right is 2:3:6. When cables of the same length are wound on winding wheels 11 of different diameters, the bending curvature of the cable is different. When the cable is bent after aging treatment, the anti-aging performance of the cable is determined according to the number of cracks on the cable.

[0034] The detection assembly 2 includes a piezoelectric sensor 21 and an elastic detection head 22. The piezoelectric sensor 21 is of model RytranV. The elastic detection head 22 includes a sliding rod 221 and a spring 222. The sliding rod 221 is mounted on the fixed end 72 of the clamping member 7 and slides along the radial direction of the winding wheel. The tension spring 713 is mounted between the sliding rod 221 and the fixed end 72 of the clamping member 7. The end of the sliding rod 221 close to the winding wheel 11 abuts against the cable and has a conical surface. When the rotating ring 12 rotates, the rotating wheel and the clamping member 7 move spirally to the left, and the cable is wound on the winding wheel 11. The sliding rod 221 follows the clamping assembly. When the component moves and moves along, and a gap appears in the cable due to bending, one end of the sliding rod 221 moves downward and causes the pressure value of the piezoelectric sensor 21 to change, triggering the piezoelectric sensor 21 to output a pressure signal change, thereby quantifying the number and depth of cracks. The number of cracks on the cable is calculated by counting the number of times the pressure value of the piezoelectric sensor 21 changes, and the size of the cracks on the cable is calculated by calculating the value of the pressure change on the piezoelectric sensor 21. The data after cable aging is analyzed by the above data. When the cable is wound on winding wheels 11 with different storage, the curvature of the cable bending is different. The bending situation of the cable after aging is further analyzed by data comparison.

[0035] In other embodiments of the present invention, the detection component 2 is an infrared distance sensor, model KeyenceIL-; when detecting the data after the cable is bent, the infrared distance sensor is driven to move by the rotating ring 12, and the change in the distance between it and the cable surface is detected by the infrared distance sensor. When cracks appear on the cable surface, the distance between it and the cable surface changes, and the data can reflect the number of cracks and the depth of the cracks on the cable after bending.

[0036] The fixing member 6 includes a mounting plate 61 and a screw 62, wherein the screw 62 is threadedly connected to the mounting plate 61, and the mounting plate 61 is fixedly arranged on the winding wheel 11; when fixing the cable, one end of the cable is placed between the mounting plate 61 and the screw 62, and the bottom of the screw 62 is rotated to make contact with one end of the cable to fix the cable.

[0037] When the locking cam 711 is unlocked, the locking cam 712 is locked, and the locking cam 713 is locked, so that the winch 7 can be unlocked and the winch can be unlocked, so that the winch 7 can be unlocked when the winch is unlocked. When the movable end 71 of the clamping member 7 is out of contact with the cable, the pressing plate presses the other end of the cable on the winding wheel 11 to prevent the cable from escaping from the winding wheel 11.

[0038] Between the two adjacent winding wheels 11, a limiting rod 15 is fixedly provided on the winding wheel 11 on the left, and a limiting groove 16 is provided on the winding wheel 11 on the right, and the limiting rod 15 is slidably provided in the limiting groove 16; when the cable is gradually wound in a spiral shape on the winding wheel 11, the winding wheel 11 on the right gradually slides to the right.

[0039] A mounting groove 5 is provided at the bottom of the winding wheel 11, and all the clamping members 7 are slidably arranged in the mounting groove 5. In the initial position, the right sides of the winding wheels 11 are close to each other. When the cable winding is completed, the winding wheels 11 are away from each other, so that the clamping members 7 slide in the mounting groove 5.

[0040] The driving device 3 is a rotary motor. The leftmost winding wheel 11 is connected to the output shaft of the rotary motor. The rotation of the rotary motor drives the winding wheel 11 to rotate, thereby causing the rotating wheel to move spirally to the left on the winding wheel 11.

[0041] The pressure detector 4 includes a mounting platform 41, an electric telescopic rod 42, a puncture needle 44 and a pressure sensor 43; when the cables on each winding wheel 11 are wound, the pressure sensor 43 is driven down by the electric telescopic rod 42, and the same pressure is applied to the cables on each winding wheel 11, and the force required for the cable to be pierced through the protective layer after bending is calculated. The pressure sensor 43 model is HSCRRRNNRAA, and the degree of cable aging is detected. The cable puncture force on multiple winding rollers can be compared with each other. At the same time, when the same cable is punctured multiple times, the winding wheel 11 is driven to rotate by the driving motor. The cable is punctured every time the cable rotates one circle, so that the distance of the cable puncture is the same each time. The force required for puncture on the same cable can be compared to avoid inaccurate puncture data. The puncture data of cables with different curvatures are compared to study the changes in the force required for puncture under different curvatures, and then study the changes in the hardness of the cable after aging.

[0042] A torque tester 8 for stretching the cable is also provided on one side of each winding wheel 11. The torque tester 8 includes a linear motor 81, a locking piece 82 and a torque meter 83; the torque meter 83 model is HBMTB, and the locking piece 82 is an electric clamp. When the torsional resistance of the cable after aging is tested, when the torsional resistance of the cable can be tested, the cable end is removed from the clamping piece 7 and locked by the locking piece 82, and then the rotating motor and the winding wheel 11 are decoupled, and the cable is pulled by the linear motor 81 to rotate. Since different cables are wound on the winding wheel 11 with different numbers of turns, when the linear motor 81 drives the torque meter 83 to move, the force required to straighten the cable is also different. After the cable is straightened, the number of turns of each cable is also different. Therefore, the force required to twist the cable by different numbers of turns can be calculated by different values ​​on the torque meter 83, and then the torsional resistance of the cable can be studied. At the same time, multiple test data can be compared and studied.

[0043] Working principle of the present invention:

[0044] The cable is then wound around the reel 11 and the cable is then reeled off, and the reel 11 is rotated until all the cables are wound around the reel 11 with different diameters. When the cable is wound, the reel 11 is rotated until the reel 11 is in contact with the cable and the reel 11 is in contact with the cable. The surfaces slide relative to each other, and the surface of the cable is detected by the detection component 2 arranged on the clamping part 7. When cables of the same length are wound on winding wheels 11 of different diameters, the bending resistance of the cable is judged by the number of cracks on the cable, and a comparative study is performed through multiple groups of data; the pressure resistance of the cable can be detected by the pressure detector 4. When the winding wheel 11 rotates, the pressure resistance detection can be performed on multiple groups of cables at the same intervals. The data collection is more accurate, avoiding the different spacing between different groups of cables, which leads to lower comparability of the collected data; the cable is straightened by the torque tester 8. Since the number of turns of the cable wound on the winding wheels 11 of different diameters is different, after the cable is straightened, the number of turns of each cable is also different. By comparing the force required for the cable to be twisted by different turns, the torsion resistance of the cable after aging can be compared and studied.

[0045] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
