Description

Technical Field

[0001] The present invention relates to the technical field of cable test equipment, and particularly to a coiled cable bending test equipment. Background Art

[0002] Cables need to be able to connect two interfaces with different directions, so the bent state is normal during their use. On the one hand, it is necessary to ensure that the conductive core cannot be easily broken during use to cause an open circuit. On the other hand, it is necessary to ensure that the protective sleeve cannot be broken when bent at a large angle, resulting in the exposure of the conductive part. Therefore, before being sold, the bending resistance performance of the cable needs to be detected.

[0003] Chinese Patent with application number CN202411146795.7 provides a cable bending test device and test method, including an experimental table and two clamping mechanisms. The clamping mechanism includes a clamping component and a constant force component. The constant force component includes a rotating shaft, a rotating ring, and a winding and unwinding rope. The rotating shaft and the rotating ring are connected by a first elastic member. One end of the winding and unwinding rope is fixed on the rotating ring, and the other end is wound around the rotating ring and then connected to the clamping component through a second elastic member. However, the heat generated when the cable is bent will affect the bending test result, and the impurities on the cable surface are also likely to affect the structure of the bending test.

[0004] When the cable is bent back and forth, heat will be generated in the cable body, and heat will also be generated at the upper turning wheel and the lower turning wheel. The heat will affect the cable bending test. When there are impurities on the cable, during the cable bending test, the impurities will damage the cable body, thereby affecting the cable bending test result. Summary of the Invention

Detailed implementation manners

[0022] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0023] Embodiment 1 As Figures 1 to 3 shown, this embodiment discloses a winding cable bending test device. There is a reciprocating bending table 1, and an upper steering wheel 2 and a lower steering wheel 3 are arranged on the reciprocating bending table 1. After the cable enters the reciprocating bending table 1, the cable will turn downward through the upper steering wheel 2, and then the cable turns upward through the lower steering wheel 3, and then with the reciprocating movement of the reciprocating bending table 1, a bending test is carried out on the cable.

[0024] On both sides of the lower end of the reciprocating bending table 1, there are brackets 6. A cross frame 7 is arranged between the two brackets 6. A track 8 is arranged at the top of the cross frame 7. A support plate 9 is arranged between the track 8 and the cross frame 7. A slider 10 is arranged at the lower end of the reciprocating bending table 1. The slider 10 slides on the track 8. The whole device is supported by the assistance of the brackets 6. The slider 10 can slide reciprocally and be limited on the track 8, so that the reciprocating bending table 1 can slide reciprocally along the track 8, improving the convenience of using the device.

[0025] Mounting brackets 11 are provided at both ends of the track 8. An auxiliary wheel 12 is rotatably provided on the mounting bracket 11. A transmission belt 13 is provided outside the auxiliary wheel 12. Both ends of the transmission belt 13 are provided on the slider 10. A motor 14 is also provided on the cross frame 7. The output end of the motor 14 is connected to the auxiliary wheel 12 for transmission. A control box 15 is also provided on the bracket 6. After the motor 14 is started, the output end of the motor 14 drives the rotation of the auxiliary wheel 12, and the rotation of the auxiliary wheel 12 causes the transmission belt 13 to move, thereby causing the slider 10 to move along the track 8. Through the reciprocating rotation of the motor 14, the reciprocating movement of the slider 10 is realized, and then the reciprocating bending table 1 makes a reciprocating movement. And the motor 14 is controlled by the control box 15, thereby controlling the moving speed of the reciprocating bending table 1.

[0026] A lower side wheel 601 is rotatably provided on the bracket 6 near the lower steering wheel 3, and an upper side wheel 602 is rotatably provided on the bracket 6 near the upper steering wheel 2. The positions of the upper side wheel 602 and the lower side wheel 601 correspond to those of the upper steering wheel 2 and the lower steering wheel 3 respectively. The cable on the side of the lower steering wheel 3 is deflected by the lower side wheel 601, and the cable on the side of the upper steering wheel 2 is deflected by the upper side wheel 602. Both sides of the cable are fixed to the bracket 6 to ensure more stability when the cable is subjected to a bending test.

[0027] During the use of this embodiment, first fix one end of the cable to the bracket 6, then pass the cable through the lower side wheel 601 for deflection so that the cable is parallel to the track 8, and then make the cable enter the reciprocating bending table 1.

[0028] The cable that enters the reciprocating bending table 1 first passes through the lower side of the lower steering wheel 3 for deflection obliquely upward, and then the cable passes through the upper side of the upper steering wheel 2 and returns to a state parallel to the track 8 again. After that, the cable passes through the upper side wheel 602 vertically downward, and then the cable is fixed to the bracket 6 to ensure the stability of the cable during the bending test.

[0029] After the cable is installed and fixed, the motor 14 is controlled by the control box 15 to perform reciprocating operation. During the reciprocating operation of the motor 14, the output end of the motor 14 drives the reciprocating rotation of the auxiliary wheel 12, and the reciprocating rotation of the auxiliary wheel 12 causes the transmission belt 13 to perform reciprocating movement, thereby causing the slider 10 to perform reciprocating movement on the track 8. The reciprocating movement of the slider 10 drives the reciprocating movement of the reciprocating bending table 1.

[0030] During the reciprocating movement of the reciprocating bending table 1, the cable is bent with the assistance of the upper steering wheel 2 and the lower steering wheel 3, and the number of reciprocating movements of the reciprocating bending table 1 is recorded, and then the bending test of the cable is completed until the end.

[0031] Embodiment Two A drum cable bending test device based on Embodiment 1 generates heat in the cable body during the reciprocating bending process. Heat is also generated at the upper steering wheel 2 and the lower steering wheel 3. The heat will affect the cable bending test. When there are impurities on the cable, during the cable bending test, the impurities will damage the cable body, thereby affecting the cable bending test results. Therefore, the following technical solutions are proposed: As Figures 1 to 7 shown, an auxiliary unit 4 is further provided between the upper steering wheel 2 and the lower steering wheel 3. An opening 5 is provided in the middle of the auxiliary unit 4. The cable located between the upper steering wheel 2 and the lower steering wheel 3 will pass through the opening 5 on the auxiliary unit 4. Through the assistance of the auxiliary unit 4, the impurities on the cable body can be cleaned and the temperature can be lowered.

[0032] The auxiliary unit 4 includes a main rod body 401. Extension rods 402 are provided at both the upper and lower parts of the main rod body 401. A cavity 403 is provided inside the extension rod 402. A piston plate 404 is slidably arranged in the cavity 403. A jet hole 405 is provided at the center of the main rod body 401. A connecting rod 406 is provided on one side of the piston plate 404 close to the jet hole 405. A baffle 407 is provided at the end of the connecting rod 406. A through hole 408 with the same diameter as the jet hole 405 is provided on the baffle 407. A heat-expandable liquid is provided in the cavity 403. During the cable bending test, as heat is generated at the upper steering wheel 2 and the lower steering wheel 3, the heat will increase the temperature near the cavity 403 through air conduction. Then the heat-expandable liquid in the cavity 403 will expand due to heat. The heat-expandable liquid uses mercury or alcohol. Thus, the piston plate 404 moves in the cavity 403. The movement of the piston plate 404 will drive the baffle 407 to move through the connecting rod 406. In the initial state, the through hole 408 on the baffle 407 coincides with the jet hole 405. Therefore, after the baffle 407 moves, the through hole 408 and the jet hole 405 will be misaligned, thereby changing the amount of gas ejected from the jet hole 405.

[0033] A collar 409 is slidably arranged at the position of the orifice of the air jet hole 405. A cleaning sleeve 410 is rotatably arranged inside the collar 409. A brush 411 is arranged on one side of the cleaning sleeve 410 close to the opening 5. Blades 412 are arranged on the inner wall of the cleaning sleeve 410. When the air jet hole 405 ejects gas, the gas acts on the blades 412, causing the cleaning sleeve 410 to rotate. The rotation of the cleaning sleeve 410 causes the brush 411 to rotate. When the gas acts on the blades 412, it also causes the collar 409 to move towards the cable, bringing the brush 411 closer to the cable. When the brush 411 contacts the cable, the rotation of the brush 411 can clean the impurities on the surface of the cable. At the same time, the gas ejected from the air jet hole 405 acts on the cable to cool it, and then the gas acts inside the reciprocating bending table 1, thereby cooling the inside of the reciprocating bending table 1. In the initial state, there is a distance between the brush 411 and the cable.

[0034] One side of the extension rod 402 located at the upper part of the main rod body 401 faces the upper steering wheel 2, and one side of the extension rod 402 located at the lower part of the main rod body 401 faces the lower steering wheel 3. The extension rod 402 is parallel to the ground. The upper extension rod 402 is close to the upper steering wheel 2, and the lower extension rod 402 is close to the lower steering wheel 3. Therefore, the two extension rods 402 can specifically monitor the temperature.

[0035] A limit groove 413 is arranged at the position of the baffle 407 inside the air jet hole 405 of the main rod body 401. When the baffle 407 slides in the limit groove 413, the air jet hole 405 will be misaligned with the air passing hole 408. A limit ring 414 is arranged on one side of the cavity 403 close to the air jet hole 405. When the baffle 407 moves, it will be limited by the limit groove 413, and when the piston plate 404 moves, it will also be limited by the limit ring 414, making the use of the device more stable.

[0036] An annular groove 415 is arranged at the position of the collar 409 inside the air jet hole 405. The collar 409 slides in the annular groove 415. A spring 416 is also arranged between the collar 409 and the annular groove 415. The spring 416 is located on the side of the collar 409 away from the brush 411. When the collar 409 moves, it is limited by the annular groove 415. And after the air jet hole 405 stops jetting gas, the position of the collar 409 is restored by the assistance of the spring 416, improving the convenience of using the device.

[0037] On both sides of the main rod body 401, air pipes 417 are provided. The air pipes 417 are communicated with the air jet holes 405. On one side where the two air pipes 417 are close to each other, a connector 418 is provided. The connector 418 is communicated with the main pipe. The air pipes 417 pass through the reciprocating bending table 1, and the connector 418 is located outside the reciprocating bending table 1. The main pipe supplies air to the two air pipes 417, so that the air jet holes 405 on both sides of the cable can eject gas, thereby realizing the cleaning and cooling of the cable. Among them, the heat dissipation efficiency of the cable depends on the jet rate of the air jet holes 405, which can be adjusted according to the type of the actually measured cable. The upper turning wheel 2 and the lower turning wheel 3 of the reciprocating bending table 1 are the main heat generation positions, and the cable is in a bent state at the upper turning wheel 2 and the lower turning wheel 3. Therefore, the gas ejected from the air jet holes 405 can carry the heat generated here to the outside for heat dissipation. Therefore, when the cable is at the reciprocating bending table 1, it is most affected by temperature. Cooling the reciprocating bending table 1 can reduce the influence of temperature on the cable. The cable outside the reciprocating bending table 1 is less affected by the temperature rise of the reciprocating bending table 1, and heat dissipation is carried out by natural air cooling here.

[0038] During the use of this embodiment, there will be sliding friction between the cable and the upper turning wheel 2. As the test progresses, heat will be generated between the cable and the upper turning wheel 2. Similarly, heat will also be generated between the cable and the lower turning wheel 3. In order to reduce the influence of heat on the cable bending test, when the cable bending reaches the set number threshold, the main pipe starts to supply air. The gas in the main pipe is evenly distributed into the two air pipes 417, and then the gas in the air pipes 417 enters the air jet holes 405, so that the air jet holes 405 eject gas to cool the cable, and at the same time, the gas ejected from the air jet holes 405 will also clean the dust on the surface of the cable.

[0039] If there are impurities on the surface of the cable, or stones are embedded in the cable epidermis, or there are impurities on the cable epidermis, at this time, with the reciprocating movement of the reciprocating bending table 1, due to the existence of impurities, there will be sliding friction between the cable and the upper turning wheel 2, and more heat will be generated by the sliding friction. Therefore, the temperature of the contact surface between the cable and the upper turning wheel 2 will be higher than the other side.

[0040] At this time, if there are impurities on the contact surface between the cable and the upper steering wheel 2, the heat generated at the upper steering wheel 2 will be higher than that at the lower steering wheel 3. Therefore, the expansion volume of the heat-expandable liquid in the cavity 403 of the extension rod 402 corresponding to the upper steering wheel 2 is larger. The expansion of the heat-expandable liquid in the cavity 403 causes the piston plate 404 to move. The movement of the piston plate 404, assisted by the connecting rod 406, causes the baffle plate 407 to move, thereby increasing the degree of misalignment between the air jet hole 405 and the air passing hole 408. As a result, the air jet volume of the air jet hole 405 corresponding to the upper extension rod 402 is smaller than that of the air jet hole 405 corresponding to the lower extension rod 402. The air jet hole 405 corresponding to the lower extension rod 402 is facing the contact surface between the cable and the upper steering wheel 2. Therefore, when the air jet volume of this air jet hole 405 increases, on the one hand, it will cause the surface temperature of the cable to drop. On the other hand, after the air jet volume of the air jet hole 405 increases, the force acting on the fan blade 412 by the gas will also increase. When the force acting on the fan blade 412 by the gas increases beyond the elastic force of the spring 416, the collar 409 corresponding to the lower extension rod 402 will move towards the cable, and the cleaning sleeve 410 will also move towards the cable. This can not only make the brush 411 approach the cable but also make the gas ejected from the air jet hole 405 focus on the cable surface, enhancing the effects of wind cooling and wind impurity removal.

[0041] During this process, when the wind acts on the fan blade 412, it will cause the fan blade 412 to rotate, and then cause the cleaning sleeve 410 to rotate. When the cleaning sleeve 410 gradually moves towards the cable and the brush 411 contacts the cable, the brush 411 will clean the impurities on the contact surface between the cable and the upper steering wheel 2 as it rotates with the cleaning sleeve 410, making the cleaning effect of the cable better.

[0042] Similarly, if there are impurities on the contact surface between the cable and the lower steering wheel 3, the air jet volume of the air jet hole 405 corresponding to the upper extension rod 402 increases, and the collar 409 corresponding to the upper extension rod 402 moves towards the cable, causing the cleaning sleeve 410 and the brush 411 to rotate and approach the cable. On the one hand, it focuses the wind force to enhance the heat dissipation and cleaning effects. On the other hand, it makes the brush 411 rotate to clean the contact surface between the cable and the lower steering wheel 3, improving the usage effect of the equipment.

[0043] After the above measures are taken and it is difficult to clean the impurities on the surface of the cable, the heat generated at the reciprocating bending table 1 will continue to increase. As the heat increases, the piston plates 404 in the upper and lower extension rods 402 will gradually move to the limit distance. After the piston plates 404 in the two extension rods 402 move to the limit distance, the jet apertures of the two jet holes 405 will shrink. However, the jet apertures of the two jet holes 405 are the same. At this time, the gas volume in the main pipe remains unchanged. When the jet apertures of the jet holes 405 shrink, the gas flow rate ejected from the jet holes 405 will increase. After the gas flow rate increases, the force exerted by the gas on the fan blades 412 will increase, causing the ring sleeve 409 to move to the limit distance, and the rotation speed of the cleaning sleeve 410 is the maximum. In this state, the two cleaning sleeves 410 will approach the cable but not touch it. The focused wind power of the two cleaning sleeves 410 achieves the best heat dissipation effect on the cable and the reciprocating bending table 1, and the focused wind power acting on the cable is beneficial to the cleaning of impurities. The two brush hairs 411 will stick to the surface of the cable and apply pressure, making the cleaning effect of the brush hairs 411 on the cable better, ensuring the stability of the cable during the bending test.

[0044] Embodiment III This embodiment provides a method for using a drum cable bending test device, including the following steps: Step 1: Fix one end of the cable on the bracket 6, then let the cable pass through the lower wheel 601 for turning, and then the cable passes through the reciprocating bending table 1.

[0045] Step 2: Then the cable passes through the upper wheel 602 vertically downward, and the cable is fixed on another bracket 6.

[0046] Step 3: Control the motor 14 to reciprocate through the control of the control box 15, so that the reciprocating bending table 1 reciprocates. When the reciprocating bending table 1 reciprocates, a bending test is performed on the cable and the number of reciprocating movements is recorded.

[0047] Step 4: Dissipate the heat generated when the cable is bent through the auxiliary unit 4, and clean the impurities on the surface of the cable.

[0048] The main functions achieved by the present invention are as follows: By setting components such as the extension rod 402, heat-expandable liquid, fan blade 412, ring sleeve 409, spring 416, and baffle 407, during the cable bending test, heat will be generated at the reciprocating bending table 1. With the assistance of the heat-expandable liquid, the piston plate 404 moves, so that the air jet hole 405 and the air passing hole 408 are misaligned. As a result, the gas ejected from the air jet hole 405 can be focused on the position with a higher temperature on the cable surface for cooling. And with the assistance of the fan blade 412, the cleaning sleeve 410 can rotate and approach the cable, enabling the cleaning sleeve 410 to focus the wind force on the cable. At the same time, the brush 411 can be attached to the cable surface for impurity cleaning. When the reciprocating bending table 1 continues to heat up, the cleaning sleeves 410 in both directions simultaneously focus the wind force on the cable for cooling, and the two brushes 411 rotate and are attached to the cable for impurity cleaning, improving the stability of the cable during the bending test.
