Description

Technical Field

[0001] This invention relates to the field of metal wire rope testing technology, and in particular to a device for testing the tensile strength of metal wire rope. Background Technology

[0002] Metal wire ropes are widely used in hoisting, mining transportation, bridge cables, elevator traction, and other fields. Their tensile strength is a core indicator for measuring the safety and service life of wire ropes. During factory inspection and pre-use safety assessments, wire ropes must undergo tensile tests using specialized testing equipment to obtain key parameters such as ultimate tensile force and elongation at break.

[0003] Existing wire rope tensile strength testing devices typically include a base, a clamping mechanism, and a force application mechanism. The force application mechanism usually uses a hydraulic cylinder or electric actuator to directly apply axial tension to the wire rope, while the clamping mechanism uses clamps to fix both ends of the wire rope to the testing platform.

[0004] However, existing technologies have the following shortcomings: traditional clamping mechanisms mostly use fixed clamping blocks or simple screw clamping methods, and the clamping force is not adjustable or has a limited adjustment range. When the diameter of the wire rope changes or there is oil or rust on the surface, the friction between the clamping block and the wire rope is insufficient, and slippage is likely to occur during the test, which not only leads to the distortion of test data, but may also cause safety accidents due to the wire rope popping out; secondly, the clamping brackets of existing devices are mostly fixed or have only simple guide structures. When the hydraulic cylinder applies a large pulling force, the bracket bears an eccentric load, which is prone to shaking or even tilting, causing the pulling force direction to deviate from the wire rope axis, affecting the test accuracy, and accelerating equipment wear; in addition, there is a lack of secondary reinforcement methods for the ends of the wire rope, and the ends of the wire rope are prone to detach from the clamping mechanism under high tensile conditions. Therefore, this application proposes a tensile strength testing device for metal wire ropes to solve the above problems. Summary of the Invention

[0005] The purpose of this application is to provide a tensile strength testing device for metal wire ropes, addressing the problems mentioned in the background art where traditional clamping mechanisms often employ fixed clamping blocks or simple screw clamping methods, resulting in non-adjustable or limited clamping force. When the wire rope diameter changes or the surface is contaminated with oil or rust, the friction between the clamping block and the wire rope is insufficient, leading to slippage during testing. This not only distorts the test data but may also cause safety accidents due to the wire rope popping out. Secondly, existing devices often use fixed clamping supports or only simple guide structures. When a large pulling force is applied by the hydraulic cylinder, the support bears an eccentric load, easily causing swaying or even tilting, resulting in the pulling force direction deviating from the wire rope axis, affecting test accuracy, and accelerating equipment wear. Furthermore, the lack of secondary reinforcement methods for the wire rope ends makes it easy for the wire rope ends to detach from the clamping mechanism under high tensile conditions.

[0006] To achieve the above objectives, this application provides the following technical solution: a tensile strength testing device for metal wire rope, comprising a base plate, and the testing device further comprising: The first hydraulic cylinder is fixedly installed on the top of the base plate, and a protective shell is fixedly installed on the top of the base plate, with the protective shell fitted onto the first hydraulic cylinder. The mounting base is provided in two parts, both of which are located on the top of the base plate; The fixing mechanism consists of two parts: a lower anti-slip clamp, a bracket, a second hydraulic cylinder, a lifting plate, two rectangular rods, and an upper anti-slip clamp. The lower anti-slip clamp is fixedly installed on the top of the corresponding mounting base, the bottom end of the bracket is fixedly installed on the corresponding mounting base, the second hydraulic cylinder is fixedly installed on the bottom of the bracket, the lifting plate is fixedly installed on the top of the second hydraulic cylinder, the top ends of the two rectangular rods are fixedly installed on the bottom of the lifting plate, the top of the mounting base has two rectangular slots, the bottom ends of the rectangular rods are slidably connected in the corresponding rectangular slots, and the upper anti-slip clamp is fixedly installed on the bottom of the lifting plate, cooperating with the lower anti-slip clamp. A stabilizing component is disposed on the top of the base plate and cooperates with the corresponding bracket. The stabilizing component improves the movement stability of the bracket. The reinforcement mechanism is provided in two parts, which are respectively fixedly installed on the opposite side of the two mounting seats. The reinforcement mechanism is used to improve the fixation stability of the two ends of the wire rope.

[0007] Using the above structure, a first hydraulic cylinder pulls the right mounting base to apply tension to the wire rope. A protective shell covers the outside of the first hydraulic cylinder for efficient protection. Fixing mechanisms on the two mounting bases clamp the two ends of the wire rope respectively. The lower anti-slip block is fixed to the top of the mounting base. The second hydraulic cylinder pushes the lifting plate to press the upper anti-slip block downwards to tighten the wire rope. The upper and lower blocks cooperate to form a reliable clamping force. A rectangular rod inserted into a rectangular groove provides guidance for the lifting plate to prevent deflection. The clamping force can be precisely adjusted by the oil pressure of the second hydraulic cylinder to adapt to wire ropes of different diameters and surface conditions, avoiding the risk of slippage. The stabilizing component supports the right bracket to remain stable under high tension. The reinforcement mechanism performs secondary locking on the ends of the wire rope to prevent the ends from coming out of the clamps. The entire device solves the problems of non-adjustable clamping force, easy slippage, and bracket swaying in traditional clamping mechanisms, improving testing accuracy and safety.

[0008] Preferably, a slide rod is fixedly installed at the bottom of the output shaft of the first hydraulic cylinder, and a groove is provided on the top of the base plate. The bottom end of the slide rod is slidably connected inside the groove. When the first hydraulic cylinder pushes the right mounting seat to move to the left for a tensile test, the slide rod slides synchronously along the groove, providing horizontal guidance for the output shaft of the first hydraulic cylinder. This prevents the piston rod of the hydraulic cylinder from bending vertically or radially when subjected to large tensile forces, ensuring that the direction of the tensile force always coincides with the axis of the wire rope. The groove also bears part of the weight of the hydraulic cylinder output shaft, reducing the lateral load on the front seal of the hydraulic cylinder and extending the service life of the hydraulic cylinder. At the same time, the length of the groove limits the maximum stroke of the hydraulic cylinder, avoiding excessive stretching that could damage the wire rope or equipment, and improving the stability and safety of the testing process.

[0009] Preferably, two sliders are fixedly installed at the bottom of the mounting base on the right side, and two slide rails are fixedly installed at the top of the base plate. The sliders are slidably connected to the top of the corresponding slide rails. When the first hydraulic cylinder pushes the right mounting base to the left, the sliders slide smoothly along the slide rails. The slide rails provide precise linear guidance for the mounting base, preventing it from swaying or tilting during movement. This ensures that the right clamping mechanism and the left clamping mechanism are always coaxial, so that the tension on the wire rope is along the axial direction. This avoids additional bending stress that could cause test data distortion due to skewing. The cooperation between the slide rails and sliders also bears part of the weight of the mounting base and the fixing mechanism, reducing the vertical load on the first hydraulic cylinder, making the stretching action smoother and more stable, and improving the repeatability of the testing device.

[0010] Preferably, two reinforcing rods are fixedly installed on the top of the base plate. The top ends of both reinforcing rods are fixedly installed on the left side of the left-side bracket. By fixing the two reinforcing rods on the top of the base plate and the top ends of both reinforcing rods are fixedly installed on the left side of the left-side bracket, the left-side bracket remains stationary during the test and bears all the tension transmitted by the wire rope. The reinforcing rods rigidly connect the bracket to the base plate, share the bending moment at the bottom of the bracket, and prevent the bracket from tilting backward or deforming under large tension. The two reinforcing rods are symmetrically arranged to ensure uniform force distribution. The reinforcing rods are made of high-strength steel, and their inclined support structure has better bending stiffness than vertical support, effectively suppressing the horizontal displacement of the top of the bracket, ensuring the absolute stability of the left-side fixed clamping point, providing a reliable benchmark for the right-side tension measurement, and improving the accuracy of the test data.

[0011] Preferably, two stabilizing rods are fixedly installed on the top of the lifting plate. The top ends of the two stabilizing rods pass through the corresponding brackets and are slidably connected to the brackets. When the second hydraulic cylinder pushes the lifting plate to lift and lower, causing the upper anti-slip clamp to press or release the wire rope, the stabilizing rods slide synchronously within the brackets, providing vertical guidance for the lifting plate and preventing it from swaying forward or backward or tilting left or right during the lifting process. This ensures that the clamping surfaces of the upper and lower anti-slip clamps are always parallel, allowing the wire rope to be evenly compressed. This avoids damage to the wire rope due to excessive local pressure caused by the tilt of the upper clamp or slippage caused by uneven clamping force. The stabilizing rods also bear part of the weight of the lifting plate and the upper clamp, reducing the lateral load on the second hydraulic cylinder, extending the service life of the hydraulic cylinder, and improving the stability and repeatability of the clamping action.

[0012] Preferably, the stabilizing component includes two moving rods and two U-shaped frames. The bottom ends of the two U-shaped frames are fixedly installed on the top of the base plate, and the top ends of the two moving rods are respectively fixedly installed on the front and rear sides of the right-side bracket. The moving rods are slidably sleeved on the corresponding U-shaped frames, and the bottom ends of the two moving rods are slidably connected to the top of the base plate. By setting the stabilizing component, when the right-side mounting seat moves to the left under the push of the first hydraulic cylinder, the right-side bracket moves forward accordingly, and the moving rods slide synchronously within the U-shaped frames. The U-shaped frames provide precise linear guidance for the moving rods, preventing the right-side bracket from swaying back and forth or swinging laterally during movement, ensuring that the right-side clamping mechanism is always aligned with the left-side clamping mechanism. The sliding contact between the moving rods and the base plate increases the support points, further improving the movement stability, making the bracket move smoothly during high-tension tests, and avoiding additional impact loads caused by swaying.

[0013] Preferably, a spring is fixedly installed on the U-shaped frame, and a sliding plate is slidably mounted on the U-shaped frame. One end of the spring is fixedly mounted on the sliding plate. By fixing the spring on the U-shaped frame and sliding the sliding plate on the U-shaped frame, with one end of the spring fixed on the sliding plate, when the right support drives the moving rod to move to the left, the sliding plate moves with the moving rod and compresses the spring. The spring's elasticity acts as a buffer, absorbing the instantaneous impact when the first hydraulic cylinder starts and stops, avoiding wire rope breakage or abnormal test data due to sudden changes in tension. After the test, the spring assists in pushing the moving rod and the support to the right to reset, reducing the load when the first hydraulic cylinder retracts. The elasticity of the spring can also compensate for the small gap between the moving rod and the U-shaped frame, reducing swaying. This elastic guiding structure improves the vibration absorption capacity and service life of the stabilizing component, and is especially suitable for fatigue testing conditions with frequent loading and unloading.

[0014] Preferably, the reinforcement mechanism includes two fixed plates, a motor, a rotating roller, an L-shaped rod, a first electric push rod, a rotating seat, a clamping rod, a second electric push rod, a limiting rod, and a turntable. One end of each of the two fixed plates is fixedly mounted on the top of its corresponding mounting base. The motor is fixedly mounted on the rear fixed plate. The rear end of the rotating roller is fixedly mounted on the motor's output shaft, and the front end of the rotating roller is rotatably connected to the front fixed plate. The rotating roller has a circular hole, and the inner wall of the circular hole and the front fixed plate have the same through hole. One end of the L-shaped rod is fixedly mounted on the front fixed plate. The first electric push rod is fixedly mounted on one side of the L-shaped rod. The rotating seat is fixedly mounted on the output shaft of the first electric push rod. The clamping rod is fixedly mounted on one side of the rotating seat, with one end of the clamping rod passing through the through hole and located within the circular hole. The second electric push rod is fixedly mounted on one side of the L-shaped rod, and one end of the limiting rod is fixed... Mounted on the output shaft of the second electric push rod, the turntable is fixedly sleeved on the rotating roller. Multiple limiting grooves are provided on the turntable, and the other end of the limiting rod engages with the corresponding limiting groove. After the end of the wire rope passes through the circular hole on the rotating roller, the motor drives the rotating roller to rotate, winding the wire rope around the roller. The first electric push rod pushes the clamping rod into the circular hole to press the wire rope and prevent it from loosening. The second electric push rod pushes the limiting rod into the limiting groove on the turntable to lock the rotating roller. This winding reinforcement method significantly increases the friction at the end of the wire rope, providing higher resistance to pull-out compared to traditional clamping blocks. It is especially suitable for large-diameter or well-lubricated wire ropes. The number of winding turns is adjustable to adapt to different length requirements. The engagement of the limiting rod and the limiting groove prevents the rotating roller from reversing under tension. The double locking ensures that the end of the wire rope will not slip out even under extreme tension, significantly improving testing safety.

[0015] Preferably, a slip ring is fixedly installed on the fixed plate located on the front side. The slip ring is slidably sleeved on the limiting rod. By fixing the slip ring on the fixed plate located on the front side and slidably sleeved on the limiting rod, when the second electric push rod pushes the limiting rod to move back and forth to insert or exit the limiting groove on the turntable, the slip ring provides precise linear guidance for the limiting rod, preventing the limiting rod from deviating or getting stuck during movement, ensuring that the end of the limiting rod can be accurately aligned with the limiting groove and smoothly inserted. The slip ring also bears part of the weight of the limiting rod, reducing the cantilever load of the second electric push rod, making the locking action smoother and more reliable. At the same time, the limiting effect of the slip ring also limits the maximum stroke of the limiting rod, avoiding the second electric push rod from overextending and causing the limiting rod to collide with the turntable or detach itself, thus improving the stability and repeatability of the locking operation of the reinforcement mechanism.

[0016] Preferably, a tension sensor and a protective box are fixedly installed on the left side of the mounting base located on the right. The tension sensor is located inside the protective box, and a controller is fixedly installed on the top of the base plate. The tension sensor detects the tension value applied to the wire rope by the first hydraulic cylinder in real time and transmits the signal to the controller. The controller displays the tension curve and records the maximum tension at the time of breakage. The protective box isolates the tension sensor from the external environment to prevent damage to the sensor from fragments or dust flying from the broken wire rope during the test. It also prevents operators from accidentally touching the sensor and causing reading deviations. The controller can set the tension loading rate and safety threshold. When the tension exceeds the set value, the hydraulic cylinder will automatically stop moving to prevent equipment overload. The controller also controls the coordinated movement of the first hydraulic cylinder, the second hydraulic cylinder, the motor, and each electric push rod to realize the automated testing process and improve testing efficiency and data accuracy.

[0017] The beneficial effects of this invention are: 1. By setting a first hydraulic cylinder to pull the right mounting seat to apply tension to the wire rope, the protective shell is fitted over the first hydraulic cylinder to achieve efficient protection. The fixing mechanisms on the two mounting seats clamp the two ends of the wire rope respectively. The lower anti-slip clamp is fixed to the top of the mounting seat. The second hydraulic cylinder pushes the lifting plate to make the upper anti-slip clamp press down on the wire rope. The upper and lower clamps cooperate to form a reliable clamping force. The rectangular rod is inserted into the rectangular groove to provide guidance for the lifting plate to prevent deflection. The clamping force can be precisely adjusted by the oil pressure of the second hydraulic cylinder to adapt to wire ropes of different diameters and surface conditions and avoid the risk of slippage. The stabilizing component supports the right bracket to remain stable under high tension. The reinforcement mechanism locks the ends of the wire rope a second time to prevent the ends from coming out of the clamps. The whole device solves the problems of non-adjustable clamping force, easy slippage and bracket shaking of traditional clamping mechanisms, and improves the testing accuracy and safety. 2. By setting a stabilizing component, when the right mounting base moves to the left under the push of the first hydraulic cylinder, the right bracket moves forward accordingly. The moving rod slides synchronously within the U-shaped frame. The U-shaped frame provides precise linear guidance for the moving rod, preventing the right bracket from swaying back and forth or swinging laterally during movement. This ensures that the right clamping mechanism is always aligned with the left clamping mechanism. The sliding contact between the moving rod and the base plate increases the support points, further improving the movement stability. This makes the bracket move smoothly during high tensile tests and avoids additional impact loads caused by shaking. 3. After the end of the wire rope is passed through the round hole on the rotating roller, the motor drives the rotating roller to rotate and wind the wire rope around the roller. The first electric push rod pushes the clamping rod into the round hole to press the wire rope to prevent it from loosening. The second electric push rod pushes the limiting rod to insert into the limiting groove on the turntable to lock the rotating roller. This winding reinforcement method greatly increases the friction of the end of the wire rope and has a higher pull-out resistance compared with the traditional clamping block. It is especially suitable for large-diameter or well-lubricated wire ropes. The number of winding turns is adjustable to adapt to different length requirements. The cooperation between the limiting rod and the limiting groove prevents the rotating roller from reversing under tension. The double locking ensures that the end of the wire rope will not slip out under the ultimate tension, which significantly improves the safety of the test. 4. The tension sensor detects the tension applied to the wire rope by the first hydraulic cylinder in real time and transmits the signal to the controller. The controller displays the tension curve and records the maximum tension at the time of breakage. The protective box isolates the tension sensor from the external environment to prevent damage to the sensor from debris or dust flying from the broken wire rope during the test. It also prevents operators from accidentally touching the sensor and causing reading deviations. The controller can set the tension loading rate and safety threshold. When the tension exceeds the set value, the hydraulic cylinder will automatically stop to prevent the equipment from overloading. The controller also controls the coordinated movement of the first hydraulic cylinder, the second hydraulic cylinder, the motor, and each electric push rod to realize the automated testing process and improve testing efficiency and data accuracy. This invention uses a second hydraulic cylinder to precisely adjust the clamping force of the upper and lower anti-slip clamps, adapting to steel wire ropes of different diameters and preventing slippage; the stabilizing component, together with the reinforcing rod, ensures the smooth movement of the support, and the direction of the tension always coincides with the axis of the steel wire rope; the reinforcement mechanism uses a winding roller, a clamping rod, and a limiting rod for double locking to prevent the end from coming off, thus improving testing accuracy and safety.

The sliding rod 3 slides horizontally along the inner wall of the sliding groove 4, providing horizontal guidance and constraint for the output shaft of the first hydraulic cylinder 2.

[0022] Two mounting seats 6 are provided on the top of the base plate 1, located on the left and right sides of the base plate 1 respectively. Two sliders 7 are fixedly installed at the bottom of the mounting seat 6 on the right side, and two slide rails 8 are fixedly installed on the top of the base plate 1. The sliders 7 are slidably connected to the top of the corresponding slide rails 8, and the sliders 7 slide linearly along the top surface of the slide rails 8, providing precise guidance for the horizontal movement of the mounting seat 6 on the right side.

[0023] Each mounting base 6 is equipped with a fixing mechanism at its top, which includes a lower anti-slip clamp 9, a bracket 11, a second hydraulic cylinder 12, a lifting plate 13, two rectangular rods 15, and an upper anti-slip clamp 16. The lower anti-slip clamp 9 is fixedly installed on the top of the corresponding mounting base 6, and the bottom end of the bracket 11 is fixedly installed on the corresponding mounting base 6.

[0024] At the mounting base 6 on the left side, two reinforcing rods 21 are fixedly installed on the top of the base plate 1. The top ends of the two reinforcing rods 21 are fixedly installed on the left side of the bracket 11 on the left side. The reinforcing rods 21 establish a rigid connection between the left bracket 11 and the base plate 1, and share the bending moment borne by the bottom of the bracket 11.

[0025] A stabilizing assembly is also provided on the top of the base plate 1, which is located on the top of the base plate 1 and cooperates with the support 11 on the right side. The stabilizing assembly includes two moving rods 17 and two U-shaped frames 18. The bottom ends of the two U-shaped frames 18 are fixedly installed on the top of the base plate 1, and the top ends of the two moving rods 17 are respectively fixedly installed on the front and rear sides of the support 11 on the right side. The moving rods 17 are slidably sleeved on the corresponding U-shaped frames 18, and the bottom ends of the two moving rods 17 are slidably connected to the top of the base plate 1. A spring 19 is fixedly installed on the U-shaped frame 18, and a sliding plate 20 is slidably sleeved on the U-shaped frame 18. One end of the spring 19 is fixedly installed on the sliding plate 20, and the sliding plate 20 moves synchronously with the moving rods 17 and makes elastic contact with the spring 19.

[0026] Each mounting base 6 has a reinforcement mechanism on its opposite side. The reinforcement mechanism includes two fixed plates 22, a motor 23, a rotating roller 24, an L-shaped rod 27, a first electric push rod 28, a rotating seat 29, a clamping rod 30, a second electric push rod 31, a limiting rod 32, and a turntable 34. One end of each fixed plate 22 is fixedly mounted on the top of its corresponding mounting base 6. The motor 23 is fixedly mounted on the rear fixed plate 22. The rear end of the rotating roller 24 is fixedly mounted on the output shaft of the motor 23, and the front end of the rotating roller 24 is rotatably connected to the front fixed plate 22. The rotating roller 24 has a circular hole 25, and the inner wall of the circular hole 25 and the front fixed plate 22 have the same through hole 26. One end of the L-shaped rod 27 is fixedly mounted on the front fixing plate 22. The first electric push rod 28 is fixedly mounted on one side of the L-shaped rod 27. The rotating seat 29 is fixedly mounted on the output shaft of the first electric push rod 28. The abutting rod 30 is fixedly mounted on one side of the rotating seat 29, with one end of the abutting rod 30 passing through the through hole 26 and located inside the round hole 25. The second electric push rod 31 is fixedly mounted on one side of the L-shaped rod 27. One end of the limiting rod 32 is fixedly mounted on the output shaft of the second electric push rod 31. The turntable 34 is fixedly sleeved on the rotating roller 24. The turntable 34 has multiple limiting grooves 35, and the other end of the limiting rod 32 cooperates with the corresponding limiting groove 35. A slip ring 33 is fixedly mounted on the front fixing plate 22. The slip ring 33 slides on the limiting rod 32, providing linear guidance for the forward and backward movement of the limiting rod 32.

[0027] A tension sensor 37 and a protective box 36 are fixedly installed on the left side of the mounting base 6 on the right side. The tension sensor 37 is located inside the protective box 36. A controller 38 is fixedly installed on the top of the base plate 1. The tension sensor 37 is electrically connected to the controller 38.

[0028] During testing, the two ends of the steel wire rope to be tested are passed through the rotating rollers 24 of the reinforcement mechanism on the left and right mounting bases 6, respectively. The ends of the steel wire rope pass through the round holes 25. The motor 23 drives the rotating rollers 24 to rotate, and the ends of the steel wire rope are wrapped around the rotating rollers 24. After several turns, the first electric push rod 28 pushes the rotating base 29 to drive the clamping rod 30 into the round holes 25 to press the steel wire rope. The second electric push rod 31 pushes the limiting rod 32 to insert into the limiting groove 35 on the turntable 34 to lock the rotating rollers 24, thus completing the reinforcement and fixing of the ends of the steel wire rope. Subsequently, the middle section of the wire rope is placed between the lower anti-slip clamp 9 and the upper anti-slip clamp 16 on the left and right mounting seats 6 respectively. The second hydraulic cylinder 12 pushes the lifting plate 13 to move downward. The lifting plate 13 drives the upper anti-slip clamp 16 to press the wire rope downward. The rectangular rod 15 slides along the rectangular groove 10 to provide guidance for the lifting plate 13. The stabilizing rod 14 slides along the bracket 11 to prevent the lifting plate 13 from tilting. The upper anti-slip clamp 16 and the lower anti-slip clamp 9 cooperate to firmly clamp both ends of the wire rope.

[0029] The first hydraulic cylinder 2 is activated, and its output shaft pushes the right mounting seat 6 to the left. The slider 7 slides along the slide rail 8, the slide rod 3 slides along the slide groove 4, and the moving rod 17 slides within the U-shaped frame 18, compressing the spring 19. The spring 19 absorbs the impact force during activation. The left support 11 is rigidly connected to the base plate 1 via the reinforcing rod 21 and remains stationary. The right support 11 moves smoothly to the left under the constraint of the stabilizing component. The clamping mechanisms on both sides remain coaxially aligned, and the wire rope is subjected to tension along the axial direction. The tension sensor 37 detects the tension value in real time and transmits it to the controller 38. The controller 38 records the tension curve. When the wire rope breaks or the tension reaches a set threshold, the controller 38 controls the first hydraulic cylinder 2 to stop. After the test, the spring 19 assists in pushing the right mounting seat 6 back to the right, and all hydraulic cylinders and electric push rods return to their initial positions. The clamping mechanism and reinforcing mechanism are released, and the wire rope is removed. Throughout the process, the protective shell 5 protects the first hydraulic cylinder 2, the protective box 36 isolates and protects the tension sensor 37, and the guiding mechanisms ensure the smoothness of the movement and the accuracy of the test data.

[0030] It should be noted that the specific models of the first hydraulic cylinder 2, the second hydraulic cylinder 12, the motor 23, the first electric push rod 28, the second electric push rod 31, the force sensor 37, and the controller 38 used can be selected by those skilled in the art. Furthermore, the above-mentioned components, including the first hydraulic cylinder 2, the second hydraulic cylinder 12, the motor 23, the first electric push rod 28, the second electric push rod 31, the force sensor 37, and the controller 38, are all existing technologies and will not be elaborated upon in this solution.

[0031] Working principle: In use, firstly, connect the first hydraulic cylinder 2, the second hydraulic cylinder 12, the motor 23, the first electric push rod 28, the second electric push rod 31, the tension sensor 37, and the controller 38 to an external power source. Then, pass both ends of the steel wire rope to be tested through the rotating rollers 24 of the reinforcement mechanism on the left and right mounting bases 6, respectively. The ends of the steel wire rope pass through the round hole 25. The motor 23 drives the rotating roller 24 to rotate, winding the ends of the steel wire rope around the rotating roller 24. After several turns, the first electric push rod 28 pushes the rotating base 29 to drive the clamping rod 30 into the round hole 25 to press it down. The wire rope is secured by the second electric push rod 31 pushing the limit rod 32 into the limit groove 35 on the turntable 34, locking the rotating roller 24 and completing the reinforcement and fixation of the wire rope end. Then, the middle section of the wire rope is placed between the lower anti-slip clamp 9 and the upper anti-slip clamp 16 on the left and right mounting seats 6 respectively. The second hydraulic cylinder 12 pushes the lifting plate 13 downwards, causing the upper anti-slip clamp 16 to press the wire rope downwards. The rectangular rod 15 slides along the rectangular groove 10 to guide the lifting plate 13, and the stabilizing rod 14 slides along the bracket 11 to prevent the lifting plate 13 from tilting. The upper anti-slip clamp 16... The 6 and lower anti-slip clamps 9 work together to firmly clamp both ends of the wire rope. The first hydraulic cylinder 2 is activated, and its output shaft pushes the right mounting base 6 to the left. The slider 7 slides along the slide rail 8, the slide rod 3 slides along the slide groove 4, and the moving rod 17 slides within the U-shaped frame 18, compressing the spring 19. The spring 19 absorbs the impact force during startup. The left support 11 is rigidly connected to the base plate 1 via the reinforcing rod 21 and remains stationary. The right support 11 moves smoothly to the left under the constraint of the stabilizing components. The clamping mechanisms on both sides remain coaxially aligned, and the wire rope is subjected to tension along the axial direction. The tension sensor... The tension value is detected in real time and transmitted to the controller 38. The controller 38 records the tension curve. When the wire rope breaks or the tension reaches the set threshold, the controller 38 controls the first hydraulic cylinder 2 to stop. After the test, the spring 19 assists in pushing the right mounting seat 6 to reset to the right. All hydraulic cylinders and electric push rods return to their initial positions, the clamping mechanism and the reinforcement mechanism are released, and the wire rope is removed. Throughout the process, the protective shell 5 protects the first hydraulic cylinder 2, and the protective box 36 isolates and protects the tension sensor 37. All guide mechanisms ensure the smoothness of the movement and the accuracy of the test data.
