Description

Technical Field

[0001] This invention relates to the field of tension control testing equipment, specifically to a tension control testing device and method for a steel wire rope drum in an intelligent vehicle. Background Technology

[0002] Steel cables play a vital role in automobiles, primarily for traction, braking, suspension, and load-bearing. For example, steel cables are used in the braking system to transmit braking force; in the suspension system, they connect the vehicle body and tires, providing support and shock absorption; and in the traction system, they are used for towing trailers. The quality of the steel cables directly affects the vehicle's safety. Low-quality steel cables are prone to breakage or wear, affecting the normal operation of the braking and suspension systems, thus impacting vehicle safety.

[0003] Therefore, during automobile production, tension tests need to be conducted on the steel wire ropes purchased and used each time to determine the transient tension and critical tension of the steel wire rope at different stretching amounts, thereby determining whether the quality of the steel wire rope meets the requirements.

[0004] However, most existing tension control testing devices can only test the same section of wire rope and cannot simultaneously obtain linear and oblique tensile test results for the wire rope. Therefore, at least two sets of equipment are needed to perform linear and oblique tensile tests on the wire rope respectively. Summary of the Invention

[0005] The purpose of this invention is to provide a tension control test device and method for intelligent vehicle drum wire ropes, so as to solve the technical problem that at least two sets of equipment are needed to perform linear tension and oblique tension tests on the wire ropes respectively in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0007] A tension control testing device for a steel wire rope drum in an intelligent vehicle includes:

[0008] The rear support plate and the vertical wire storage assembly mounted on the rear support plate, and the horizontal wire storage assembly mounted on the vertical wire storage assembly, with wire rope tension rollers provided at both ends of the vertical wire storage assembly and the horizontal wire storage assembly, and the wire rope passing through the two wire rope tension rollers of the vertical wire storage assembly and the two wire rope tension rollers of the horizontal wire storage assembly in sequence.

[0009] Each of the wire rope tension rollers is provided with a clamping assembly, which is used to fix the wire rope at the contact point with the wire rope tension roller. The clamping assembly is used to fix the wire rope of the wire rope tension roller on the vertical wire storage assembly and the wire rope tension roller on the horizontal wire storage assembly. The rear support plate is equipped with a tension measuring instrument at the wire rope position between every two wire rope tension rollers.

[0010] After the ends of the wire ropes on the vertical wire storage assembly and the horizontal wire storage assembly are fixed, the wire rope tension between the two wire rope tension rollers on the horizontal wire storage assembly and the horizontal wire storage assembly, as well as the wire rope tension between the two adjacent wire rope tension rollers on the vertical wire storage assembly and the horizontal wire storage assembly, are adjusted by changing the distance between the two wire rope tension rollers on the vertical wire storage assembly and the horizontal wire storage assembly.

[0011] As a preferred embodiment of the present invention, the vertical wire storage assembly includes a first limiting mounting plate movably mounted on the rear support plate, and a first sliding base mounted at both ends of the first limiting mounting plate. The wire rope tension roller is mounted on the first sliding base, and the first sliding base moves vertically along the first limiting mounting plate under the limiting action of the first limiting mounting plate.

[0012] The inner side of the first sliding base is provided with a vibration drive assembly, which is used to drive the two wire rope tension rollers to move closer or further apart to adjust the tension of the wire rope between the two wire rope tension rollers on the vertical wire storage assembly.

[0013] As a preferred embodiment of the present invention, the horizontal storage assembly includes a second limiting mounting plate disposed on both sides of the first limiting mounting plate, and a second sliding base mounted on both ends of the second limiting mounting plate. The second sliding base moves horizontally along the second limiting mounting plate under the limiting action of the second limiting mounting plate.

[0014] The inner side of the second sliding base is also provided with a vibration drive assembly, which is used to drive the two wire rope tension rollers to move closer or further apart to adjust the tension of the wire rope between the two wire rope tension rollers on the horizontal wire storage assembly.

[0015] As a preferred embodiment of the present invention, the vibration drive assembly includes a drive motor disposed inside the wire rope tension roller, and an eccentric wheel connected to the output shaft of the drive motor, the other end of the eccentric wheel being connected to the first sliding base and the second sliding base respectively.

[0016] When the drive motor rotates, it drives the first sliding base to move along the first limiting mounting plate via the eccentric wheel, thereby driving the two wire rope tension rollers on the first limiting mounting plate to move closer or further away from each other. When the drive motor rotates, it drives the second sliding base to move along the second limiting mounting plate via the eccentric wheel, thereby driving the two wire rope tension rollers on the second limiting mounting plate to move closer or further away from each other.

[0017] As a preferred embodiment of the present invention, the wire rope tension roller on the vertical wire storage assembly and the wire rope tension roller on the horizontal wire storage assembly are on the same vertical plane, and the side curved surface of the wire rope tension roller is provided with annular rope grooves distributed in a circle. The wire rope is wound sequentially along the annular rope grooves of the wire rope tension roller on the vertical wire storage assembly and the wire rope tension roller on the horizontal wire storage assembly.

[0018] The side of the wire rope tension roller is provided with a sinking groove, the clamping assembly is installed in the sinking groove, and the wire rope passes through the clamping assembly and is clamped and fixed.

[0019] As a preferred embodiment of the present invention, the clamping assembly includes an outer through sleeve installed in the sinking trough and an inner rotating block disposed in the cavity inside the outer through sleeve. The inner rotating block rotates in both directions under the rotation drive assembly. The outer through sleeve and the inner rotating block are provided with a through hole at their center positions. The clamping assembly is installed in the sinking trough, and the hole groove of the through hole coincides with the hole groove of the annular rope groove.

[0020] The inner rotating block has multiple evenly distributed and inclined inner grooves on its side. The outer end of each inner groove forms a fixed angle with the outer tangent of the inner rotating block. The same side of the outer through sleeve has a limiting groove. A clamping rod is installed in the limiting groove, and a card seat located in the inner groove is installed on the lower surface of the clamping rod. When the inner rotating block rotates in both directions, it drives the clamping rod to move synchronously in and out.

[0021] As a preferred embodiment of the present invention, the rotary drive assembly includes a cylindrical curved panel disposed on the other side of the inner rotating block, and an oblique tooth groove disposed on the side curved surface of the cylindrical curved panel.

[0022] The same side of the outer through sleeve is provided with a helical gear that meshes with the oblique tooth groove, and the side curved surface of the outer through sleeve is provided with a servo motor connected to the helical gear.

[0023] The servo motor drives the helical gear to mesh with the helical tooth groove to drive the inner rotating block to rotate forward and backward. When the inner rotating block rotates forward and backward, it drives the clamping rod to move in and outward to clamp and fix the steel wire rope in the hole or release the steel wire rope.

[0024] In addition, the present invention also provides an automatic control method for a tension control testing device for intelligent vehicle drum wire rope, comprising the following steps:

[0025] Step 100: Move the two wire rope tension rollers of the vertical wire storage assembly and the two wire rope tension rollers of the horizontal wire storage assembly inward to the innermost end, and pass the wire rope through the two wire rope tension rollers of the vertical wire storage assembly and the two wire rope tension rollers of the horizontal wire storage assembly in sequence.

[0026] Step 200: Adjust the clamping components on the wire rope tension rollers at both ends of the vertical wire storage assembly and the horizontal wire storage assembly to clamp and fix the wire rope between every two wire rope tension rollers.

[0027] Step 300: Simultaneously drive the vibration drive assembly on the vertical wire storage assembly and the vibration drive assembly on the horizontal wire storage assembly to work, and simultaneously stretch the wire rope between the two wire rope tension rollers on the vertical wire storage assembly and the wire rope between the two wire rope tension rollers on the horizontal wire storage assembly.

[0028] Step 400: Calculate the linear tension of the wire rope between the two wire rope tension rollers on the vertical wire storage assembly and the linear tension of the wire rope between the two wire rope tension rollers on the horizontal wire storage assembly based on the driving angle of the vibration drive assembly, and obtain the transient tension and critical tension of the rope to be tested through a tension measuring instrument.

[0029] Step 500: Calculate the oblique tension of the wire rope between one of the wire rope tension rollers of the vertical wire storage assembly and one of the wire rope tension rollers of the horizontal wire storage assembly based on the driving angle of the vibration drive assembly, and obtain the transient tension and critical tension of the rope to be tested through a tension measuring instrument.

[0030] Step 600: Replace with a new wire rope segment and repeat steps 100-500 above. Analyze the relationship between the linear tensile amount and the tensile tension of the wire rope under test, analyze the relationship between the oblique tensile amount and the tensile tension of the wire rope under test, construct a rope tension control model, and automatically control the tension of the wire rope by adjusting the driving angle of the vibration drive component.

[0031] In a preferred embodiment of the present invention, in step 100, the length of the wire rope between the two wire rope tension rollers of the vertical wire storage assembly is the same as the length of the wire rope between the two wire rope tension rollers of the horizontal wire storage assembly.

[0032] As a preferred embodiment of the present invention, in step 200, after the clamping assembly clamps the wire rope between every two wire rope tension rollers, the entire wire rope is split into the wire rope segment to be tested between the two wire rope tension rollers of the vertical wire storage assembly, the wire rope segment to be tested between the two wire rope tension rollers of the horizontal wire storage assembly, and the wire rope segment to be tested between the two wire rope tension rollers on the vertical wire storage assembly and the horizontal wire storage assembly.

[0033] In calculating the tensile amount and tensile tension of each wire rope segment to be tested, each wire rope segment to be tested is independent of each other and does not affect the others.

[0034] Compared with the prior art, the present invention has the following advantages:

[0035] This invention can simultaneously obtain test data on the linear tensile amount and tensile tension of two sets of straight wire rope segments under test, and test data on the oblique tensile amount and tensile tension of one set of inclined wire rope segments under test during a single test. The implementation is simple, and no additional power or testing equipment is required when measuring the oblique tensile amount and tensile tension of the inclined wire rope segments under test. This improves the overall integration of the tension control test device. When calculating the tensile amount and tensile tension of the wire rope segments under test between the two wire rope tension rollers of the vertical wire storage assembly and between the two wire rope tension rollers of the horizontal wire storage assembly, each wire rope segment under test is independent and does not affect the others, thus improving the accuracy of the obtained test data on the linear tensile amount and tensile tension of the two sets of straight wire rope segments under test.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] like Figure 1 and Figure 2As shown, the present invention provides a tension control test device for a steel wire rope in an intelligent vehicle drum, including a rear support plate 1, a vertical wire storage assembly 2 mounted on the rear support plate 1, and a horizontal wire storage assembly 3 mounted on the vertical wire storage assembly 2. Wire rope tension rollers 4 are respectively provided at both ends of the vertical wire storage assembly 2 and the horizontal wire storage assembly 3. The steel wire rope passes through the two wire rope tension rollers 4 of the vertical wire storage assembly 2 and the two wire rope tension rollers 4 of the horizontal wire storage assembly 3 in sequence.

[0054] Each wire rope tension roller 4 is equipped with a clamping assembly 6, which is used to fix the wire rope at the contact point with the wire rope tension roller 4. The clamping assembly 6 is used to fix the wire rope of the wire rope tension roller 4 on the vertical wire storage assembly 2 and the wire rope tension roller 4 on the horizontal wire storage assembly 3. The rear support plate 1 is equipped with a tension measuring instrument 5 at the wire rope position between every two wire rope tension rollers 4.

[0055] After the ends of the wire ropes on the vertical wire storage assembly 2 and the horizontal wire storage assembly 3 are fixed, the wire rope tension between the two wire rope tension rollers 4 on the horizontal wire storage assembly 3 and the two wire rope tension rollers 4 on the vertical wire storage assembly 2, as well as the wire rope tension between the two adjacent wire rope tension rollers 4 on the horizontal wire storage assembly 3, can be adjusted by adjusting the distance between the two wire rope tension rollers 4 on the vertical wire storage assembly 2 and the two wire rope tension rollers 4 on the horizontal wire storage assembly 3.

[0056] In this embodiment, a cross-shaped vertical wire storage assembly 2 and a horizontal wire storage assembly 3 are provided. The wire rope is passed sequentially through two wire rope tension rollers 4 of the vertical wire storage assembly 2 and two wire rope tension rollers 4 of the horizontal wire storage assembly 3. After the clamping assembly 6 on the two wire rope tension rollers 4 of the vertical wire storage assembly 2 fixes the wire rope, a vertical wire rope segment to be tested is formed. After the clamping assembly 6 on the two wire rope tension rollers 4 of the horizontal wire storage assembly 3 fixes the wire rope, a horizontal wire rope segment to be tested is formed. An inclined wire rope segment to be tested is formed between two adjacent wire rope tension rollers 4 on the vertical wire storage assembly 2 and the horizontal wire storage assembly 3.

[0057] Adjusting the distance between the two wire rope tension rollers 4 on the vertical wire storage assembly 2 can change the change in the amount of tension of the steel wire rope segment to be tested in the vertical direction during continuous pressurization. Similarly, adjusting the distance between the two wire rope tension rollers 4 on the horizontal wire storage assembly 3 can change the change in the amount of tension of the steel wire rope segment to be tested in the horizontal direction during continuous pressurization. At the same time, adjusting the distance between the two wire rope tension rollers 4 on the vertical wire storage assembly 2 and the distance between the two wire rope tension rollers 4 on the horizontal wire storage assembly 3 can change the change in the amount of tension of the steel wire rope segment to be tested in the inclined direction during continuous pressurization.

[0058] By combining the transient tensile tension and critical tensile tension of the steel wire rope segments to be tested in the vertical, horizontal, and inclined directions, the relationship between the applied load and the tensile tension of the steel wire rope under test is analyzed. Based on the tensile change relationship, the dynamic deformation degree of the steel wire rope under test is analyzed. Combined with the static deformation degree under constant pressure, a rope tension control model for analyzing the tensile tension of the steel wire rope under test is constructed. Then, by combining the rope tension control model, the distance change between the two wire rope tension rollers 4 on the current vertical wire storage assembly 2, and the distance change between the two wire rope tension rollers 4 on the current horizontal wire storage assembly 3, the tension magnitude of the current steel wire rope segments to be tested in the horizontal, vertical, and inclined directions is determined.

[0059] Therefore, in a single test, this embodiment can simultaneously obtain test data on the linear tensile amount and tensile tension of two sets of straight wire rope segments under test, as well as test data on the oblique tensile amount and tensile tension of one set of inclined wire rope segments under test, making the implementation simple.

[0060] Among them, such as Figure 3 As shown, the vertical wire storage assembly 2 includes a first limiting mounting plate 21 movably mounted on the rear support plate 1, and a first sliding base 22 mounted at both ends of the first limiting mounting plate 21. The wire rope tension roller 4 is mounted on the first sliding base 22, and the first sliding base 22 moves vertically along the first limiting mounting plate 21 under the limiting action of the first limiting mounting plate 21.

[0061] The inner side of the first sliding base 22 is provided with a vibration drive assembly 7. The vibration drive assembly 7 is used to drive the two wire rope tension rollers 4 to move closer or further away from each other in order to adjust the tension of the wire rope between the two wire rope tension rollers 4 on the vertical wire storage assembly 2.

[0062] The horizontal storage assembly 3 includes a second limiting mounting plate 31 disposed on both sides of the first limiting mounting plate 21, and a second sliding base 32 installed at both ends of the second limiting mounting plate 31. The second sliding base 32 moves horizontally along the second limiting mounting plate 31 under the limiting action of the second limiting mounting plate 31.

[0063] The inner side of the second sliding base 32 is also provided with a vibration drive assembly 7. The vibration drive assembly 7 is used to drive the two wire rope tension rollers 4 to move closer or further away from each other in order to adjust the tension of the wire rope between the two wire rope tension rollers 4 on the horizontal wire storage assembly 3.

[0064] The vibration drive assembly 7 includes a drive motor 71 disposed inside the wire rope tension roller 4, and an eccentric wheel 72 connected to the output shaft of the drive motor 71. The other end of the eccentric wheel 72 is connected to the first sliding base 22 and the second sliding base 32 respectively.

[0065] When the drive motor 71 rotates, it drives the first sliding base 22 to move along the first limiting mounting plate 21 via the eccentric wheel 72, thereby driving the two wire rope tension rollers 4 on the first limiting mounting plate 21 to move closer or further away from each other. When the drive motor 71 rotates, it drives the second sliding base 32 to move along the second limiting mounting plate 31 via the eccentric wheel 72, thereby driving the two wire rope tension rollers 4 on the second limiting mounting plate 31 to move closer or further away from each other.

[0066] To obtain test data on the relationship between linear tensile strength and tensile tension of the wire rope segment to be tested, this embodiment adjusts the two wire rope tension rollers 4 on the vertical wire storage assembly 2 to their closest position and the two wire rope tension rollers 4 on the horizontal wire storage assembly 3 to their closest position. Then, the wire rope is sequentially passed around the two wire rope tension rollers 4 on the vertical wire storage assembly 2 and the two wire rope tension rollers 4 on the horizontal wire storage assembly 3 to fix the wire rope and form three wire rope segments to be tested. After adjusting the two wire rope tension rollers 4 on the vertical wire storage assembly 2 and the two wire rope tension rollers 4 on the horizontal wire storage assembly 3 to be further apart, test data on the relationship between linear tensile strength and tensile tension of the wire rope segment to be tested, as well as test data on the relationship between oblique tensile strength and tensile tension of the wire rope segment to be tested, can be obtained.

[0067] The wire rope tension roller 4 on the vertical wire storage assembly 2 and the wire rope tension roller 4 on the horizontal wire storage assembly 3 are on the same vertical plane. The side curved surface of the wire rope tension roller 4 is provided with annular rope grooves 41 distributed in a circular pattern. The wire rope is wound sequentially along the annular rope grooves 41 of the wire rope tension roller 4 on the vertical wire storage assembly 2 and the wire rope tension roller 4 on the horizontal wire storage assembly 3.

[0068] The side of the wire rope tension roller 4 is provided with a sinking groove 42, and the clamping assembly 6 is installed in the sinking groove 42. The wire rope passes through the clamping assembly 6 and is clamped and fixed.

[0069] like Figures 4 to 7 As shown, it should be noted that when determining the relationship between the tensile amount and tensile tension of the wire rope, this embodiment specifically uses clamping assembly 6 to divide the wire rope wound on the tension control test device into three segments. The tensile loads received by the horizontal wire rope segment and the vertical wire rope segment do not affect each other. Therefore, when simultaneously acquiring test data on the linear tensile amount and tensile tension of the two sets of straight wire rope segments to be tested, it is ensured that the test data on the linear tensile amount and tensile tension of the two sets of straight wire rope segments to be tested do not affect each other, thereby improving the accuracy of the measurement data.

[0070] In addition, during the movement of the two wire rope tension rollers of the vertical wire storage assembly and the two wire rope tension rollers of the horizontal wire storage assembly, the wire rope segments to be tested, distributed obliquely, are naturally stretched. This allows verification of whether the relationship between the oblique stretching amount and the stretching tension of the obliquely distributed wire rope segments to be tested is the same as the relationship between the linear stretching amount and the stretching tension of the linearly distributed wire rope segments.

[0071] The clamping assembly 6 includes an outer through sleeve 61 installed in the sinking trough 42 and an inner rotating block 62 disposed in the cavity inside the outer through sleeve 61. The inner rotating block 62 rotates in both directions under the rotation drive assembly 68. A through hole 63 is provided at the center of the outer through sleeve 61 and the inner rotating block 62. The clamping assembly 6 is installed in the sinking trough 42, and the hole 63 coincides with the hole 41 of the annular rope groove.

[0072] The inner rotating block 62 has multiple evenly distributed and inclined inner grooves 64 on its side. The outer end of each inner groove 64 forms a fixed angle with the outer tangent of the inner rotating block 62. The same side of the outer through sleeve 61 has a limiting groove 65. A clamping rod 66 is installed in the limiting groove 65. A card seat 67 located in the inner groove 64 is installed on the lower surface of the clamping rod 66. When the inner rotating block 62 rotates in both directions, it drives the clamping rod 66 to move synchronously in and out.

[0073] The rotary drive assembly 68 includes a cylindrical curved panel 681 disposed on the other side of the inner rotating block 62, and an oblique tooth groove 682 disposed on the side curved surface of the cylindrical curved panel 681.

[0074] The same side of the outer through sleeve 61 is provided with a helical gear 683 that meshes with the helical tooth groove 682, and the side curved surface of the outer through sleeve 61 is provided with a servo motor 684 that is connected to the helical gear 683.

[0075] The servo motor 684 drives the inner rotating block 62 to rotate forward and backward through the meshing of the helical gear 683 and the helical tooth groove 682. When the inner rotating block 62 rotates forward and backward, it drives the clamping rod 66 to move in and outward to clamp the wire rope in the fixed hole 63 or release the wire rope.

[0076] In this embodiment, the clamping rod 66 is installed in the inner groove 64 of the inner rotating block 62 via the card holder 67 and can move along the inner groove 64. Therefore, when the servo motor 684 drives the inner rotating block 62 to rotate forward through the engagement of the helical gear 683 and the inclined tooth groove 682, the clamping rod 66 moves toward the through hole 63 under the drive of the inner groove 64 to clamp and fix the wire rope in the through hole 63.

[0077] When the servo motor 684 drives the inner rotating block 62 to reverse through the meshing of the helical gear 683 and the helical tooth groove 682, the clamping rod 66 moves outward under the drive of the inner groove 64 to release the wire rope in the through hole 63.

[0078] In this embodiment, when there are enough clamping rods 66, multi-point clamping and fixing of the wire rope can be achieved, ensuring the clamping stability of the wire rope.

[0079] The automatic control method for the tension control test device of the intelligent vehicle drum wire rope described above is characterized by comprising the following steps:

[0080] Step 100: Move the two wire rope tension rollers of the vertical wire storage assembly and the two wire rope tension rollers of the horizontal wire storage assembly inward to the innermost end, and pass the wire rope through the two wire rope tension rollers of the vertical wire storage assembly and the two wire rope tension rollers of the horizontal wire storage assembly in sequence.

[0081] Step 200: Adjust the clamping components on the wire rope tension rollers at both ends of the vertical wire storage assembly and the horizontal wire storage assembly to clamp and fix the wire rope between each pair of wire rope tension rollers.

[0082] Step 300: Simultaneously drive the vibration drive assembly on the vertical wire storage assembly and the vibration drive assembly on the horizontal wire storage assembly to work, and simultaneously stretch the wire rope between the two wire rope tension rollers on the vertical wire storage assembly and the wire rope between the two wire rope tension rollers on the horizontal wire storage assembly.

[0083] Step 400: Calculate the linear tension of the wire rope between the two wire rope tension rollers on the vertical wire storage assembly and the linear tension of the wire rope between the two wire rope tension rollers on the horizontal wire storage assembly based on the driving angle of the vibration drive assembly. Obtain the transient tension and critical tension of the rope to be tested through a tension measuring instrument.

[0084] Step 500: Calculate the oblique tension of the wire rope between one of the wire rope tension rollers of the vertical wire storage assembly and one of the wire rope tension rollers of the horizontal wire storage assembly based on the driving angle of the vibration drive assembly, and obtain the transient tension and critical tension of the rope to be tested through a tension measuring instrument.

[0085] Step 600: Replace with a new wire rope segment and repeat steps 100-500 above. Analyze the relationship between the linear tensile amount and the tensile tension of the wire rope under test, and analyze the relationship between the oblique tensile amount and the tensile tension of the wire rope under test. Construct a rope tension control model and automatically control the tension of the wire rope by adjusting the driving angle of the vibration drive component.

[0086] In step 100, the length of the wire rope between the two wire rope tension rollers of the vertical wire storage assembly is the same as the length of the wire rope between the two wire rope tension rollers of the horizontal wire storage assembly. This ensures that the influencing factors on the test data of the linear tensile amount and tensile tension of the wire rope segment under test in two straight states are the same, thereby improving the accuracy of the test data.

[0087] In step 200, after the clamping assembly clamps the wire rope between every two wire rope tension rollers, the entire wire rope is split into the wire rope segment to be tested between the two wire rope tension rollers of the vertical wire storage assembly, the wire rope segment to be tested between the two wire rope tension rollers of the horizontal wire storage assembly, and the wire rope segment to be tested between the two wire rope tension rollers on the vertical wire storage assembly and the horizontal wire storage assembly.

[0088] In calculating the tensile amount and tensile tension of the wire rope segment to be tested between the two wire rope tension rollers of the vertical wire storage assembly and between the two wire rope tension rollers of the horizontal wire storage assembly, each wire rope segment to be tested is independent of each other and does not affect each other, thereby improving the accuracy of the test data between the linear tensile amount and tensile tension of the two sets of straight wire rope segments to be tested.
