Description

Technical Field

[0001] The present invention relates to the technical field of surface friction testing, and particularly to a research and detection system and process for the surface abrasion resistance of cable materials. Background Art

[0002] In the cable application scenario, the surface abrasion resistance of its materials is crucial. Traditional detection methods are mostly manual observation and simple friction tests, lacking accurate quantification. With the increasingly complex cable usage environment, such as in industrial environments with high friction and strong wear, ordinary detection is difficult to meet the requirements. Existing detection systems cannot comprehensively simulate various actual working conditions and cannot accurately evaluate the abrasion resistance of cable materials. Therefore, it is urgent to develop a research and detection system and process that can accurately and comprehensively detect the surface abrasion resistance of cable materials.

[0003] In the patent with the publication number CN118168904A, a wear resistance detector for wire and cable production is disclosed, which includes a bottom plate. A cushion seat is fixedly installed on the upper surface of the bottom plate. The upper sides of both sides of the cushion seat are respectively provided with arcs, and a plurality of strip-shaped openings are formed on the surfaces of the arcs. Air bags are respectively arranged at two inner corners of the cushion seat, and a plurality of strip-shaped sacs communicated with each other are arranged on the surfaces of the air bags. A wear resistance detection method for wire and cable production is also proposed. This invention patent can tighten the cable, and while tightening, automatically arrange the cable in a horizontal line distribution, ensuring that the cable will not be skewed and deformed due to pushing when the grinding head reciprocates; the use of strip-shaped sacs improves the stability of the cable after positioning, and there is a large frictional force between the two, preventing the cable from moving horizontally synchronously with the grinding head; the use of strip-shaped sacs to locally wrap the cable prevents the cable from skewing during the friction test.

[0004] The existing technology has the following defects:

[0005] It is impossible to conduct wear resistance tests under various different motion states: The existing system can only carry out wear resistance tests with a single uniform linear motion and cannot simulate the wear conditions of cables under complex motion states such as rotation, torsion, and vibration during actual use. It is also difficult to explore the wear laws of materials under different motion combinations, resulting in a large deviation between the detection results and the actual situation and being unable to accurately evaluate the wear resistance of cable materials in real scenarios. Therefore, a structure that can change various different motion states needs to be set up to accurately simulate the motions of cable rotation, torsion, vibration, etc., make the test results closer to the real use scenario, comprehensively evaluate the abrasion resistance of cable materials, deeply explore the wear laws under different motion combinations, find out the weak points of material wear resistance, and achieve the effect of improving the quality and service life of cables.

[0006] It is impossible to compare different wear resistance tests in different environments: The existing system can only conduct wear resistance tests in a single standard environment, unable to compare the wear resistance performance of cable materials in different environments such as high temperature and humidity. It is difficult to obtain data on the influence of different environmental factors on material wear, and it is impossible to accurately judge the applicability of materials in special environments. As a result, problems such as excessive wear and performance degradation are likely to occur in the selected cables in actual complex environments. Therefore, a structure that can simulate different environments and conduct synchronous tests needs to be set up. From this, the specific influence of environmental factors such as high temperature and high humidity on the wear resistance performance of cable materials can be clearly understood, and the wear degree and law of materials in different scenarios can be accurately grasped, achieving the effect of improving the pertinence of material performance and predicting service life. Summary of the Invention

[0007] In view of problems in the prior art such as the inability to conduct wear resistance tests under multiple different motion states and the inability to compare different wear resistance tests in different environments, a research and detection system and process for the surface wear resistance of cable materials are proposed.

[0008] On the one hand, the present application provides a research and detection system for the surface wear resistance of cable materials, aiming to: through the set dynamic adjustment mechanism, it can accurately simulate the movements of cable rotation, torsion, vibration, etc., making the test results closer to the actual use scenario, comprehensively evaluating the wear resistance of cable materials, deeply exploring the wear laws under different motion combinations, and finding out the weak points of material wear resistance, achieving the effect of improving the quality and service life of cables. Through the set wear resistance test component and environment simulation component, the specific influence of environmental factors such as high temperature and high humidity on the wear resistance performance of cable materials can be clearly understood, and the wear degree and law of materials in different scenarios can be accurately grasped, achieving the effect of improving the pertinence of material performance and predicting service life.

[0009] The technical solution of the present invention is: A research and detection system for the surface wear resistance of cable materials, including a detection table, an environment simulation component and a dynamic adjustment mechanism arranged on the surface of the detection table, a specimen arranged inside the dynamic adjustment mechanism, and a wear resistance test component arranged above the specimen. The wear resistance test component is used to test the wear resistance performance of the specimen. The environment simulation component is used to simulate different test environments. The dynamic adjustment mechanism is used to adjust different motion states of the specimen. The environment simulation component includes an environment simulation box fixedly installed on the outer wall of the detection table. A transparent installation cover is hinged on the outer wall of the environment simulation box. The specimens inside and outside the environment simulation box are used for performance comparison under the same dynamic state;

[0010] The dynamic adjustment mechanism includes a translation component and a vibration component fixedly installed on the outer wall of the test bench, a clamping component fixedly installed on the outer wall of the translation component, and a torsion component fixedly installed inside the translation component and the clamping component. The translation component is used to drive the specimen to translate and generate friction with the wear-resistant test component, and the torsion component is used to adjust the rotation and torsion of the specimen.

[0011] With the above solution, through the set dynamic adjustment mechanism, when the servo motor is operated, it can drive the specimen to move back and forth for wear-resistant testing under static conditions. When the torsion component is operated, it can drive the specimen to perform wear-resistant testing in a rotating and torsional state. When the vibration component is operated, it can drive the specimen to perform wear-resistant testing in a vibrating state. Thus, it can accurately simulate the movements of the cable such as rotation, torsion, and vibration, making the test results closer to the actual usage scenario, comprehensively evaluating the wear resistance of the cable material, deeply exploring the wear laws under different movement combinations, finding out the weak points of material wear resistance, and achieving the effect of improving the quality and service life of the cable.

[0012] Further, the translation component includes a translation screw rod rotatably connected to the outer wall of the test bench. Symmetrically arranged two frame-shaped frames are threadedly connected to the outer wall of the translation screw rod. A plurality of moving wheels are fixedly installed at the bottoms of the two frame-shaped frames. The frame-shaped frames translate on the test bench through the moving wheels.

[0013] With the above solution, through the set translation component, when the servo motor is operated, the output shaft of the servo motor drives the two frame-shaped frames to move back and forth on the test bench through the moving wheels through the translation screw rod for wear-resistant testing under static conditions. The moving speed and test time can be adjusted, which plays a role in driving the specimen to translate and generate friction.

[0014] Further, the clamping component includes a first support frame and a second support frame fixedly installed on the outer wall of the frame-shaped frame. A clamping ring is rotatably connected between the inner walls of the first support frame and the second support frame. Symmetrically arranged two tightening bolts are threadedly connected to the inner wall of the clamping ring. The clamping ring clamps the specimen at the center through the tightening bolts.

[0015] With the above solution, through the set clamping component, during operation, two specimens of the same specification are taken out. The two ends of the specimen are respectively passed through the inside of the two clamping rings in the same group, and the specimen is fixed at the center of the clamping ring by using the tightening bolts, which plays a role in stable clamping.

[0016] Further, the torsion component includes an annular rope slidably connected inside the frame-shaped frame and the second support frame. A plurality of knot balls are fixedly connected to the annular rope near the clamping ring. A plurality of grooves are formed on the surface of the clamping ring. The knot balls drive the clamping ring to rotate by being embedded in the grooves of the clamping ring.

[0017] Further, the torsion assembly further includes a rotating cylinder fixedly connected to the outer wall of the frame-shaped frame. The output end of the rotating cylinder is fixedly connected with a limiting screw rod. The limiting screw rod is rotatably connected to the inner wall of the frame-shaped frame. A limiting groove is formed in the inner wall of the frame-shaped frame. Part of the annular rope is wound around the outer wall of the limiting screw rod and swings in the limiting groove.

[0018] With the above solution, through the provided torsion assembly, during the rotation test, if the specimen needs to be replaced, after replacement, run the rotating cylinder in the same direction. The output end of the rotating cylinder drives the annular rope to move through the limiting screw rod, and the knot ball is embedded into the groove of the clamping ring to drive both ends of the specimen to rotate in the same direction, so that the specimen rotates, thereby performing the wear resistance test under the rotating state. During the torsion test, if the specimen needs to be replaced, after replacement, run the rotating cylinder unidirectionally or in the reverse direction to twist the specimen, thereby performing the wear resistance test under the torsion state, playing a role in driving the specimen to rotate and twist.

[0019] Further, the vibration assembly includes an opposing screw rod rotatably connected to the outer wall of the detection table. One end of the opposing screw rod is fixedly connected with a handwheel. Two connecting rods moving in opposite directions are threadedly connected to the outer wall of the opposing screw rod. Two corrugated plates are fixedly connected to the outer walls of both connecting rods. A plurality of moving grooves and a plurality of storage grooves are formed in the inner wall of the detection table. The moving grooves are used to guide the translational movement of the moving wheels. Driven by the rotation of the opposing screw rod, the corrugated plates slide between the moving grooves and the storage grooves.

[0020] With the above solution, through the provided vibration assembly, during the vibration test, if the specimen needs to be replaced, after replacement, twist the handwheel. The two connecting rods are driven by the opposing screw rod to slide in opposite directions, moving the corrugated plates from the storage grooves to the moving grooves, so that the moving wheels move back and forth on the corrugated plates, thereby generating vibration, thereby performing the wear resistance test under the vibration state, and the vibration amplitude can be adjusted by replacing the corrugated plates, playing a role in driving the specimen to vibrate.

[0021] Further, the wear resistance test assembly includes a lifting groove formed in the inner wall of the detection table. A triangular plate is slidably connected to the inner wall of the lifting groove. Two fixed columns are fixedly connected to the inner wall of the triangular plate. A pressing rod and a bearing rod are slidably connected to the inner walls of both fixed columns. The bottom of the pressing rod is fixedly connected to the top of the bearing rod. A pressing spring is fixedly connected between the inner wall of the fixed column and the top of the bearing rod. A weight tray is fixedly connected between the tops of the two pressing rods. A plurality of test weights are slidably connected to the inner wall of the weight tray.

[0022] Further, a wear-resistant head is fixedly installed at the bottom of the bearing rod. The bottom of the wear-resistant head rests on the surface of the specimen to generate friction. A through hole is formed in the inner wall of the transparent mounting cover. The bearing rod and the wear-resistant head can pass through the through hole and enter the interior of the environmental simulation box.

[0023] With the above solution, by means of the provided wear-resistant test assembly, the triangular plate is pressed down, and the wear-resistant head above the environmental simulation chamber passes through the through hole, and the external wear-resistant head and the wear-resistant head respectively rest on the surfaces of the two specimens. Test weights are added to or removed from the weight tray for pressure adjustment. The weight tray presses the bearing rod through the downward pressure rod, causing the wear-resistant head to exert pressure on the surface of the specimen, squeezing the specimen and generating different-pressure friction under the condition that the specimen is moving.

[0024] Furthermore, a servo motor and a temperature and humidity generator are fixedly connected to the outer wall of the detection table. The output shaft of the servo motor is sleeved on the outer wall of the translation screw rod, and the temperature and humidity generator adjusts the temperature and humidity in the environmental simulation chamber through a connecting pipe.

[0025] With the above solution, by means of the provided servo motor and temperature and humidity generator, the functions of providing power and changing the temperature and humidity in the environmental simulation chamber are achieved.

[0026] On the other hand, the present application provides a process for a cable material surface wear resistance research and detection system. A cable material surface wear resistance research and detection system is adopted, which includes the following steps:

[0027] Step 1: Clamp two specimens of the same specification in two groups of clamping assemblies respectively;

[0028] Step 2: Close the transparent mounting cover to form a sealed space with the environmental simulation chamber, and adjust the temperature and humidity inside;

[0029] Step 3: Press down the wear-resistant test assembly to the surface of the specimen and adjust the pressure;

[0030] Step 4: Operate the translation assembly to drive the specimen to move back and forth for wear resistance testing under static conditions;

[0031] Step 5: If it is necessary to replace the specimen, after replacement, operate the torsion assembly in the same direction to drive the specimen for wear resistance testing in a rotating state;

[0032] Step 6: If it is necessary to replace the specimen, after replacement, operate the torsion assembly unidirectionally or in the reverse direction to drive the specimen for wear resistance testing in a torsional state;

[0033] Step 7: If it is necessary to replace the specimen, after replacement, operate the vibration assembly to drive the specimen for wear resistance testing in a vibrating state;

[0034] Step 8: Record the data and make comparisons.

[0035] Adopt the above scheme. Take out two specimens of the same specification, pass the two ends of the specimens through the interiors of two clamping rings in the same group respectively, and use the tightening bolts to fix the specimens at the centers of the clamping rings. Close the transparent mounting cover to form a sealed space with the environmental simulation chamber. Operate the constant temperature and humidity generator, input temperature and humidity gas into the environmental simulation chamber through the connecting pipe and adjust it. Press down the triangular plate, and the wear-resistant heads above the environmental simulation chamber pass through the through holes and respectively rest on the surfaces of the two specimens with the external wear-resistant heads. Add or subtract test weights in the weight tray to adjust the pressure. The weight tray squeezes the bearing rod through the pressing rod, so that the wear-resistant heads generate pressure on the surfaces of the specimens. Operate the servo motor to drive the specimens to move back and forth. The moving speed and test time can be adjusted, and data recording is carried out simultaneously. During the rotation test, operate the rotating cylinder in the same direction to make the specimens rotate, so as to carry out the wear-resistant test under the rotating state, and data recording is carried out simultaneously. During the torsion test, operate the rotating cylinder unidirectionally or reversely to make the specimens twist, so as to carry out the wear-resistant test under the torsion state, and data recording is carried out simultaneously. During the vibration test, operate the vibration assembly to make the specimens vibrate, so as to carry out the wear-resistant test under the vibration state, and the vibration amplitude can be adjusted by replacing the corrugated plate, and data recording is carried out simultaneously. Finally, integrate all the data and conduct data comparison.

[0036] The beneficial effects of the present invention:

[0037] Through the set dynamic adjustment mechanism, operate the servo motor to drive the specimens to move back and forth for the wear-resistant test under static conditions, operate the torsion assembly to drive the specimens to carry out the wear-resistant tests under the rotating and torsion states, and operate the vibration assembly to drive the specimens to carry out the wear-resistant test under the vibration state. Thus, the movements such as rotation, torsion, and vibration of the cable can be accurately simulated, making the test results closer to the actual use scenario, being able to comprehensively evaluate the wear resistance of the cable material, deeply explore the wear laws under different movement combinations, find out the weak points of the material's wear resistance, and achieve the effect of improving the quality and service life of the cable.

[0038] Through the set wear-resistant test assembly and environmental simulation assembly, close the transparent mounting cover to form a sealed space with the environmental simulation chamber. Operate the constant temperature and humidity generator, input temperature and humidity gas into the environmental simulation chamber through the connecting pipe and adjust it. Press down the triangular plate, and the wear-resistant heads above the environmental simulation chamber pass through the through holes and respectively rest on the surfaces of the two specimens with the external wear-resistant heads. Add or subtract test weights in the weight tray to adjust the pressure. The weight tray squeezes the bearing rod through the pressing rod, so that the wear-resistant heads generate pressure on the surfaces of the specimens. Thus, different environments can be simulated and synchronous tests can be carried out, accurately grasping the wear degree and laws of the material under different scenarios, and achieving the effect of improving the pertinence of the material performance and predicting the service life.

[0039] Through the provided vibration assembly, during vibration testing, if it is necessary to replace the specimen, after replacement, turn the handwheel. Driven by the counter-directional screw, the two connecting rods slide in opposite directions, moving the corrugated plate from the storage groove to the moving groove, causing the moving wheel to move back and forth on the corrugated plate, thereby generating vibration, and thus conducting wear resistance testing under vibration conditions. The vibration amplitude can be adjusted by replacing the corrugated plate, and rotation and torsion can be carried out simultaneously with vibration to test the wear resistance performance under more complex conditions, playing a role in driving the specimen to vibrate.

[0055] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present invention in conjunction with the drawings of the specification.

[0056] Example 1

[0057] Refer to Figure 1 - Figure 13 , which is the first embodiment of the present invention, provides a detection system for studying the surface wear resistance of cable materials, including a detection table 1, an environment simulation component 3 and a dynamic adjustment mechanism 4 arranged on the surface of the detection table 1, a specimen 5 arranged inside the dynamic adjustment mechanism 4, and a wear resistance test component 2 arranged above the specimen 5. The wear resistance test component 2 is used to test the wear resistance of the specimen 5, the environment simulation component 3 is used to simulate different test environments, and the dynamic adjustment mechanism 4 is used to adjust different motion states of the specimen 5. The environment simulation component 3 includes an environment simulation box 31 fixedly installed on the outer wall of the detection table 1. A transparent mounting cover 32 is hinged on the outer wall of the environment simulation box 31. The specimens 5 inside and outside the environment simulation box 31 are used for performance comparison under the same dynamic conditions.

[0058] Refer to Figure 3 , the dynamic adjustment mechanism 4 includes a translation component 42 and a vibration component 45 fixedly installed on the outer wall of the detection table 1, a clamping component 43 fixedly installed on the outer wall of the translation component 42, and a torsion component 44 fixedly installed inside the translation component 42 and the clamping component 43. The translation component 42 is used to drive the specimen 5 to translate and generate friction with the wear resistance test component 2, and the torsion component 44 is used to adjust the rotation and torsion of the specimen 5.

[0059] Specifically, the dynamic adjustment mechanism 4 can adjust the specimen 5 to form different states such as rotation, torsion, and vibration. When the specimen 5 rotates, the wear resistance of different surfaces of the specimen 5 can be tested. When the specimen 5 is twisted, the wear resistance of the lower surface under torsion of the specimen 5 can be tested. When the specimen 5 vibrates, the wear resistance of the surface under different pressures of the specimen 5 can be tested. Moreover, rotation and torsion can be carried out simultaneously with vibration to test the wear resistance under more complex conditions. The environmental simulation chamber 31 and the transparent mounting cover 32 can form a sealed space through the opening and closing of the hinge. When the specimen 5 needs to be installed or replaced, the transparent mounting cover 32 needs to be opened for replacement. The transparent mounting cover 32 can also observe the friction state in real time.

[0060] By setting the dynamic adjustment mechanism 4, running the servo motor 41 can drive the specimen 5 to move back and forth for wear resistance testing under static conditions. Running the torsion assembly 44 can drive the specimen 5 to perform wear resistance testing under rotational and torsional states. Running the vibration assembly 45 can drive the specimen 5 to perform wear resistance testing under vibration states. Thus, the movements of the cable such as rotation, torsion, and vibration can be accurately simulated, making the test results closer to the actual use scenario, comprehensively evaluating the wear resistance of the cable material, deeply exploring the wear laws under different movement combinations, finding the weak points of material wear resistance, and achieving the effect of improving the quality and service life of the cable.

Two symmetrically arranged frame-shaped frames 421 are threadedly connected to the outer wall of the translation screw 422. A plurality of moving wheels 423 are fixedly installed at the bottoms of the two frame-shaped frames 421. The frame-shaped frames 421 are translated on the detection table 1 through the moving wheels 423.

[0062] By setting the translation component 42, running the servo motor 41, the output shaft of the servo motor 41 drives the two frame-shaped frames 421 to move back and forth on the detection table 1 through the translation screw 422 and the moving wheels 423 for wear resistance testing under static conditions. The moving speed and test time can be adjusted, which plays a role in driving the specimen 5 to translate and generate friction.

[0063] Refer to Figure 5 - Figure 6 For the clamping component 43, the first support frame 431 and the second support frame 433 are fixedly installed on the outer wall of the frame-shaped frame 421. A clamping ring 432 is rotatably connected between the inner walls of the first support frame 431 and the second support frame 433. Two symmetrically arranged tightening bolts 434 are threadedly connected to the inner wall of the clamping ring 432. The clamping ring 432 clamps the specimen 5 at the center through the tightening bolts 434.

[0064] With the clamping assembly 43 provided, during operation, take out two specimens 5 of the same specification, pass the two ends of the specimen 5 through the inside of two clamping rings 432 of the same group respectively, and use the tightening bolt 434 to fix the specimen 5 at the center of the clamping ring 432, playing a role in stable clamping.

[0065] Refer to Figure 7 - Figure 9 As shown in FIGS. - [FIG. NUMBER NOT CLEAR IN ORIGINAL], the torsion assembly 44 includes an annular rope 441 slidably connected inside the frame-shaped frame 421 and the second support frame 433. A plurality of knot balls 442 are fixedly connected to the annular rope 441 near the clamping ring 432. A plurality of grooves are formed on the surface of the clamping ring 432. The knot balls 442 drive the clamping ring 432 to rotate by being embedded in the grooves of the clamping ring 432. The torsion assembly 44 further includes a rotating cylinder 444 fixedly connected to the outer wall of the frame-shaped frame 421.

A limiting groove 445 is formed on the inner wall of the frame-shaped frame 421. Part of the annular rope 441 is wound around the outer wall of the limiting screw 443 and swings in the limiting groove 445.

[0066] With the torsion assembly 44 provided, during the rotation test, if it is necessary to replace the specimen 5, after replacement, operate the rotating cylinder 444 in the same direction. The output end of the rotating cylinder 444 drives the annular rope 441 to move through the limiting screw 443, and the knot balls 442 drive the two ends of the specimen 5 to rotate in the same direction by being embedded in the grooves of the clamping ring 432, so that the specimen 5 rotates, thereby performing the wear resistance test under the rotating state. During the torsion test, if it is necessary to replace the specimen 5, after replacement, operate the rotating cylinder 444 unidirectionally or in the reverse direction, so that the specimen 5 is twisted, thereby performing the wear resistance test under the twisted state, playing a role in driving the specimen 5 to rotate and twist.

[0067] Refer to Figure 10 - Figure 11 As shown in FIGS. - [FIG. NUMBER NOT CLEAR IN ORIGINAL], the vibration assembly 45 includes an opposing screw 452 rotatably connected to the outer wall of the test bench 1. One end of the opposing screw 452 is fixedly connected to a handwheel 451. Two connecting rods 453 that move oppositely are threadedly connected to the outer wall of the opposing screw 452. Two corrugated plates 454 are fixedly connected to the outer walls of the two connecting rods 453. A plurality of moving grooves 455 and a plurality of receiving grooves 456 are formed on the inner wall of the test bench 1. The moving grooves 455 are used to guide the translation of the moving wheels 423. Driven by the rotation of the opposing screw 452, the corrugated plates 454 slide between the moving grooves 455 and the receiving grooves 456.

[0068] Through the provided vibration assembly 45, during vibration testing, if it is necessary to replace the specimen 5, after replacement, turn the handwheel 451. Driven by the opposed screw 452, the two connecting rods 453 slide in opposite directions, moving the corrugated plate 454 from the storage groove 456 to the moving groove 455, causing the moving wheel 423 to move back and forth on the corrugated plate 454, thereby generating vibration, so as to conduct wear resistance testing under vibration conditions. Moreover, the vibration amplitude can be adjusted by replacing the corrugated plate 454, which plays a role in driving the specimen 5 to vibrate.

[0069] Refer to Figure 12 - Figure 13 , the wear resistance testing assembly 2 includes a lifting groove 21 opened on the inner wall of the testing table 1. A triangular plate 22 is slidably connected to the inner wall of the lifting groove 21. Two fixed columns 23 are fixedly connected to the inner wall of the triangular plate 22. A pressing rod 26 and a bearing rod 27 are slidably connected to the inner walls of both fixed columns 23. The bottom of the pressing rod 26 is fixedly connected to the top of the bearing rod 27. A pressing spring 29 is fixedly connected between the inner wall of the fixed column 23 and the top of the bearing rod 27. A weight tray 24 is fixedly connected between the tops of the two pressing rods 26. A plurality of test weights 25 are slidably connected to the inner wall of the weight tray 24. A wear-resistant head 28 is fixedly installed at the bottom of the bearing rod 27. The bottom of the wear-resistant head 28 rests on the surface of the specimen 5 to generate friction. A through hole 34 is opened on the inner wall of the transparent mounting cover 32. The bearing rod 27 and the wear-resistant head 28 can pass through the through hole 34 and enter the interior of the environmental simulation chamber 31.

[0070] Through the provided wear resistance testing assembly 2, press the triangular plate 22. The wear-resistant head 28 above the environmental simulation chamber 31 passes through the through hole 34 and respectively rests on the surfaces of two specimens 5 with the external wear-resistant head 28. Add or subtract test weights 25 in the weight tray 24 to adjust the pressure. The weight tray 24 squeezes the bearing rod 27 through the pressing rod 26, causing the wear-resistant head 28 to generate pressure on the surface of the specimen 5, which plays a role in squeezing the specimen 5 and generating different pressure frictions in the state where the specimen 5 moves.

[0071] Refer to Figure 2 - Figure 3 , a servo motor 41 and a temperature and humidity generator 33 are also fixedly connected to the outer wall of the testing table 1.

[0082] Step 7: If it is necessary to replace the specimen 5, after replacement, operate the vibration assembly 45 to drive the specimen 5 to conduct wear resistance testing in a vibrating state.

[0083] Step 8: Record the data and make comparisons.

[0084] Working principle of the present invention:

[0085] During operation, take out two specimens 5 of the same specification, pass the two ends of the specimen 5 through the interiors of two clamping rings 432 in the same group respectively, and use the tightening bolt 434 to fix the specimen 5 at the center of the clamping ring 432.

[0086] Close the transparent mounting cover 32 to form a sealed space with the environmental simulation chamber 31, operate the constant temperature and humidity generator 33, and input temperature and humidity gas into the environmental simulation chamber 31 through the connecting pipe and adjust it (simulate normal temperature and humidity environment, the temperature can be set at 25°C, and the relative humidity is set at 60%; if it is to simulate the outdoor environment of high temperature and high humidity, the temperature can be set at 40°C, and the relative humidity is set at 80%; if it is to simulate a cold and dry environment, the temperature is set at -10°C, and the relative humidity is set at 20%).

[0087] Press down the triangular plate 22, the wear-resistant heads 28 above the environmental simulation chamber 31 pass through the through holes 34, and the external wear-resistant heads 28 are respectively placed on the surfaces of the two specimens 5. Add or subtract test weights 25 to the weight tray 24 for pressure adjustment. The weight tray 24 squeezes the bearing rod 27 through the pressing rod 26, so that the wear-resistant heads 28 generate pressure on the surfaces of the specimens 5 (for general cable materials, the pressure can be set at 5N; if it is a cable that needs to withstand greater pressure, such as a cable for industrial heavy equipment, the pressure can be increased to 10N or even higher; for thinner and softer control cables, the pressure can be set at 2N).

[0088] Operate the servo motor 41. The output shaft of the servo motor 41 drives the two frame-shaped frames 421 to move back and forth on the test bench 1 through the translation screw 422 by means of the moving wheels 423 to conduct wear resistance testing under static conditions. The moving speed and test time can be adjusted (the moving speed of the specimen 5 back and forth is generally set at 50mm / s, and the test time is set at 30 minutes; for cable materials with better wear resistance, the test time can be appropriately extended to 60 minutes; for materials with expected poor wear resistance, the test time can be shortened to 15 minutes), and data recording is carried out simultaneously.

[0089] During the rotation test, if it is necessary to replace the specimen 5, after replacement, rotate the rotating cylinder 444 in the same direction. The output end of the rotating cylinder 444 drives the annular rope 441 to move through the limit screw 443, and the knot ball 442 is embedded in the groove of the clamping ring 432 to drive both ends of the specimen 5 to rotate in the same direction, so that the specimen 5 rotates, thereby performing the wear resistance test under the rotating state, and recording data at the same time.

[0090] During the torsion test, if it is necessary to replace the specimen 5, after replacement, operate the rotating cylinder 444 unidirectionally or in the reverse direction to twist the specimen 5, thereby performing the wear resistance test under the torsion state, and recording data at the same time.

[0091] During the vibration test, if it is necessary to replace the specimen 5, after replacement, turn the handwheel 451, and drive the two connecting rods 453 to slide in opposite directions through the opposed screw 452, move the corrugated plate 454 from the storage groove 456 to the moving groove 455, so that the moving wheel 423 moves back and forth on the corrugated plate 454, thereby generating vibration, so as to perform the wear resistance test under the vibration state, and the vibration amplitude can be adjusted by replacing the corrugated plate 454, and recording data at the same time.

[0092] Finally, integrate all the data and conduct data comparison.

[0093] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
