Description

Technical Field

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

[0002] With the rapid development of modern communication technology, higher requirements have been placed on the performance and quality of communication cables. As the physical carrier of signal transmission, the tensile and torsional strength of communication cables directly affect the stability, durability and service life of communication networks. However, existing communication cable strength testing technologies and equipment have many limitations and cannot meet the industry's growing testing needs.

[0003] On the one hand, traditional testing equipment has limited functionality and struggles to perform multi-dimensional strength testing. Most devices can only perform single-item testing on tensile or torsional strength, failing to conduct multiple performance tests simultaneously, resulting in low testing efficiency. For example, in actual production, different devices are needed to perform tensile and torsional tests on the same batch of wires, which not only consumes a lot of time and equipment resources but may also introduce human error due to multiple clamping operations, affecting the accuracy and consistency of the test results. On the other hand, as the application scenarios of communication cables become increasingly complex, the demand for performance testing of cables under composite stress is becoming more urgent. However, in existing technologies, there are very few devices with multi-parameter collaborative testing capabilities, making it difficult to simulate the complex stress state under actual working conditions and accurately assess the reliability of cables in complex environments.

[0004] In summary, the development of a communication cable strength testing device capable of multi-dimensional testing of tensile and torsional strength and supporting composite stress testing has become an urgent need to improve the quality of communication cables and promote the development of the communication industry. The communication cable strength testing device of this invention was developed in response to the above background, aiming to solve the technical bottlenecks in the existing technology and provide a more efficient and accurate solution for communication cable quality testing.

An annular frame is fixedly mounted on the end of the support plate, and a lower ring plate is movably mounted within the annular frame. The device also includes:

[0008] A clamping mechanism, which is disposed in the upper ring plate and the lower ring plate, is used to clamp both ends of the wire to be tested;

[0009] A rotating mechanism is provided on the outside of the annular frame to drive the lower ring plate to rotate within the annular frame.

[0010] As a further embodiment of the present invention: the lifting mechanism includes a frame fixedly installed on the upper surface of the testing platform, a drive motor fixedly installed at the top of the frame, and a lead screw connected to the drive end of the drive motor, a limit rod fixedly installed on the outer wall of the frame, and a limit block slidably sleeved on the outer side of the limit rod, a vertical plate fixedly installed on the outer wall of the limit block, a moving block connected to the outer side of the lead screw, and a fixed connection between the moving block and the vertical plate, and the lifting plate fixedly installed on one side of the vertical plate.

[0011] As a further embodiment of the present invention: the clamping mechanism includes a locking block movably disposed in the upper ring plate and the lower ring plate. The locking block is conical, and a through hole for the wire to pass through is opened at the center of the locking block. The outer wall of the locking block has movable grooves that are evenly spaced and distributed in a ring. The upper surface of the upper ring plate and the lower surface of the lower ring plate are both fixedly installed with brackets that are evenly spaced and distributed in a ring. The ends of the brackets are located in the movable grooves. A fixing rod that passes through the brackets is fixedly installed on the inner wall of the movable grooves. The fixing rod and the brackets are movably connected. A baffle is fixedly installed at the end of the fixing rod. A spring is also sleeved on the outside of the fixing rod. One end of the spring is connected to the baffle, and the other end of the spring is connected to the bracket. The outer wall of the locking block is fixedly installed with winding pieces that are evenly spaced and distributed in a ring and aligned with the movable grooves. A rubber pad is also fixedly installed at the end of the bracket near the winding pieces. The locking block is also provided with a locking component for locking the wire outside the winding pieces.

[0012] As a further embodiment of the present invention: the locking assembly includes a clamping plate, the outer wall of the locking block has a groove, an electric telescopic rod is fixedly installed in the groove, the clamping plate is fixedly installed on the telescopic end of the electric telescopic rod, and a rubber ring is fixedly installed on the outer wall of the clamping plate near the locking block.

[0013] As a further aspect of the present invention: the side wall of the winding sheet is also provided with a slot, and the cross-section of the slot is V-shaped.

[0014] As a further embodiment of the present invention: an upper sliding ring is fixedly installed on the top inner wall of the annular frame, an upper ring groove is formed on the upper surface of the lower ring plate and the upper sliding ring is located in the upper ring groove, a lower sliding ring is fixedly installed on the lower surface of the lower ring plate, and a lower ring groove is formed on the bottom inner wall of the annular frame and the lower sliding ring is located in the lower ring groove.

[0015] As a further embodiment of the present invention: the rotating mechanism includes a mounting frame fixedly installed on the side wall of the annular frame, a stepper motor is fixedly installed in the mounting frame, and a gear is driven to the drive end of the stepper motor. A gear ring is fixedly installed on the upper surface of the lower ring plate, and the gear and the gear ring mesh with each other.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention provides a communication cable strength testing device. Through the clamping mechanism of upper and lower ring plates, the two ends of the cable can be securely locked. The lifting mechanism precisely pulls the upper ring plate to stretch the cable at a preset speed. In conjunction with the pressure sensor, the tensile data is captured in real time. The pressure signal is converted into a tensile value and transmitted to the data acquisition system. At the moment of cable breakage, the system automatically records the maximum tensile force and accurately calculates the tensile strength by combining the cross-sectional area. At the same time, a tensile-displacement curve is generated, providing comprehensive data support for the analysis of the mechanical properties of the cable.

[0018] For torsional strength testing, the rotating mechanism can drive the lower ring plate to rotate at a preset speed and angle, thereby achieving precise torsion operation on the wire. Whether it is to test the fatigue performance of the wire through multiple cycles of torsion or to obtain the maximum torsional bearing value through continuous torsion, it can be flexibly adapted. This process can accurately control the torsion parameters, ensuring the reliability and repeatability of the test results, and effectively evaluating the strength performance of the wire under torsional stress.

[0019] The device achieves a breakthrough by simultaneously performing tensile and torsional tests, simulating the combined stress state of communication cables under complex working conditions. By monitoring the changes in tensile strength under different degrees of torsion in real time, it can comprehensively evaluate the performance of the cable under combined stress, filling the gap of single testing in traditional equipment. It provides more realistic test data for the application of communication cables, significantly improving testing efficiency and the practicality of results. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] like Figures 1-9 As shown, an embodiment of the present invention provides a communication cable strength testing device, including a testing platform 101. A lifting plate 102 is movably disposed above the testing platform 101, and a lifting mechanism for driving the lifting plate 102 to move up and down. An installation groove 104 is formed on the upper surface of the lifting plate 102, and an installation opening 103 communicating with the installation groove 104 is formed at the bottom of the lifting plate 102. The inner diameter of the installation opening 103 is smaller than the inner diameter of the installation groove 104. An upper ring plate 106 is placed in the installation groove 104, and a pressure sensor 105 is disposed below the upper ring plate 106. The device 105 is disposed between the upper ring plate 106 and the mounting groove 104. A vertical rod 107 is fixedly installed on the upper surface of the testing table 101, and a support plate 108 is fixedly installed at the top of the vertical rod 107. An annular frame 109 is fixedly installed at the end of the support plate 108, and a lower ring plate 110 is movably installed in the annular frame 109. The device also includes: a clamping mechanism disposed in the upper ring plate 106 and the lower ring plate 110 for clamping both ends of the wire to be tested; and a rotating mechanism disposed on the outside of the annular frame 109 for driving the lower ring plate 110 to rotate in the annular frame 109.

[0032] One end of the communication cable to be tested can be placed in the upper ring plate 106 and locked by the clamping mechanism in the upper ring plate 106. The other end of the communication cable to be tested can be placed in the lower ring plate 110 and locked by the clamping mechanism in the lower ring plate 110. When it is necessary to test the tensile strength of the communication cable, the lifting plate 102 can be moved upward by the lifting mechanism, so that the cable clamped and fixed in the upper ring plate 106 can be moved upward according to the preset stretching speed, thereby stretching the communication cable. During the stretching process, the pressure sensor 105 can detect the pressure applied by the upper ring plate 106, thereby detecting the tensile force on the cable and transmitting the pressure signal to the data acquisition and processing system. When the wire breaks, the lifting mechanism stops working, and the data acquisition and processing system records the maximum tensile force value. The tensile strength can be calculated based on the cross-sectional area of ​​the wire, and a curve showing the relationship between tensile force and displacement can also be generated. If it is necessary to test the torsional strength of the wire, the lower ring plate 110 can be rotated in the annular frame 109 by the rotating mechanism according to the preset speed and torsion angle, thereby realizing the torsion operation of the communication wire. The fatigue resistance of the wire can be tested by repeated torsion, or it can be continuously torsion until the wire breaks, which is convenient for testing the maximum torsion value that the wire can withstand. Furthermore, tensile testing and torsion testing can be performed simultaneously, which can be used to test the tensile strength of the wire under different torsion degrees, and the effect is better.

[0033] As one embodiment of the present invention, please refer to Figure 1 The lifting mechanism includes a stand 201 fixedly installed on the upper surface of the testing table 101. A drive motor 202 is fixedly installed at the top of the stand 201, and a lead screw 203 is driven to the drive end of the drive motor 202. A limit rod 204 is fixedly installed on the outer wall of the stand 201, and a limit block 206 is slidably sleeved on the outer side of the limit rod 204. A vertical plate 207 is fixedly installed on the outer wall of the limit block 206. A moving block 205 is driven to the outer side of the lead screw 203, and the moving block 205 and the vertical plate 207 are fixedly connected. The lifting plate 102 is fixedly installed on one side of the vertical plate 207. When it is necessary to control the lifting plate 102 to lift, the drive motor 202 can drive the lead screw 203 to rotate, and the lead screw 203 can drive the moving block 205 to move up and down, causing the vertical plate 207 to move up and down together, thus completing the lifting operation of the lifting plate 102.

[0034] As one embodiment of the present invention, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8The clamping mechanism includes a locking block 301 movably disposed in the upper ring plate 106 and the lower ring plate 110. The locking block 301 is conical in shape, and a through hole 302 for the wire to pass through is opened at the center of the locking block 301. The outer wall of the locking block 301 has movable grooves 304 that are evenly spaced and arranged in a ring. The upper surface of the upper ring plate 106 and the lower surface of the lower ring plate 110 are both fixedly installed with brackets 303 that are evenly spaced and arranged in a ring. The ends of the brackets 303 are located in the movable grooves 304. Through brackets 303 are fixedly installed on the inner wall of the movable grooves 304. The fixing rod 305 is movably connected to the bracket 303. A baffle 307 is fixedly installed at the end of the fixing rod 305, and a spring 306 is sleeved on the outside of the fixing rod 305. One end of the spring 306 is connected to the baffle 307, and the other end of the spring 306 is connected to the bracket 303. Winding pieces 308, evenly spaced and arranged in a ring, are fixedly installed on the outer wall of the locking block 301 and are aligned with the movable groove 304. A rubber pad 309 is fixedly installed on the end of the bracket 303 near the winding pieces 308. The locking block 301 also contains... A locking assembly is provided to lock the wire on the outside of the winding piece 308. To lock the wire, the end of the wire can be passed through the through hole 302 of the locking block 301, and then wound around the outside of the winding piece 308. The number of winding pieces 308 can be freely selected as needed, but each winding piece 308 must be wound at least once. After the wire is wound around the outside of the winding piece 308, the locking assembly can lock the wire on the outside of the winding piece 308, and then the wire stretching operation can begin. During the stretching process, the wire engages with the lock assembly. The tension generated by the positioning block 301 will cause the locking block 301 in the bracket 303 to move towards the bracket 303, and cause part of the wire on the outside of the winding piece 308 to be clamped between the winding piece 308 and the rubber pad 309 at the end of the bracket 303. The greater the tensile force of the wire, the greater the clamping force applied by the winding piece 308 to the wire on its outside. This makes the clamping force applied to the wire proportional to the tensile force on the wire, which can effectively prevent the wire from coming loose due to excessive tensile force during the stretching process, resulting in better performance.

[0035] As one embodiment of the present invention, please refer to Figure 2 and Figure 3 The locking assembly includes a clamping plate 402. The outer wall of the locking block 301 has a groove, and an electric telescopic rod 401 is fixedly installed in the groove. The clamping plate 402 is fixedly installed at the telescopic end of the electric telescopic rod 401. A rubber ring 403 is fixedly installed on the outer wall of the clamping plate 402 near the locking block 301. When it is necessary to lock the wire outside the winding piece 308, the clamping plate 402 can be moved down by the electric telescopic rod 401, so that the wire outside the winding piece 308 is clamped between the rubber ring 403 at the bottom of the clamping plate 402 and the winding piece 308, which can achieve the purpose of quickly locking the wire.

[0036] As one embodiment of the present invention, please refer to Figure 2 and Figure 3 The side wall of the winding piece 308 is also provided with a slot 310, and the cross section of the slot 310 is V-shaped. When the end of the wire is wound around the outside of the winding piece 308, the end of the wire can be locked in the slot 310 of the winding piece 308, thereby preventing the wire from coming loose and making it more convenient to use.

[0037] As one embodiment of the present invention, please refer to Figure 8 An upper sliding ring 501 is fixedly installed on the top inner wall of the annular frame 109. An upper ring groove is opened on the upper surface of the lower ring plate 110, and the upper sliding ring 501 is located in the upper ring groove. A lower sliding ring 502 is fixedly installed on the lower surface of the lower ring plate 110. A lower ring groove is opened on the bottom inner wall of the annular frame 109, and the lower sliding ring 502 is located in the lower ring groove. Lubricant can be directly added through the gap between the toothed ring 604 and the annular frame 109, so that the lubricant can enter the gap between the upper sliding ring 501 and the lower ring plate 110 and the gap between the lower sliding ring 502 and the lower ring plate 110. With the assistance of the upper sliding ring 501 and the lower sliding ring 502, the rotation process of the lower ring plate 110 in the annular frame 109 can be smoother, and the use effect is better.

[0038] As one embodiment of the present invention, please refer to Figure 6 , Figure 7 and Figure 8 The rotating mechanism includes a mounting frame 601 fixedly installed on the side wall of the annular frame 109. A stepper motor 602 is fixedly installed in the mounting frame 601, and a gear 603 is connected to the drive end of the stepper motor 602. A gear ring 604 is fixedly installed on the upper surface of the lower ring plate 110, and the gear 603 and the gear ring 604 mesh with each other. When it is necessary to drive the lower ring plate 110 to rotate in the annular frame 109, the stepper motor 602 can drive the gear 603 to rotate. Since the gear 603 and the gear ring 604 on the upper surface of the lower ring plate 110 mesh with each other, the lower ring plate 110 can be driven to rotate in the annular frame 109, which is very convenient to use.

[0039] It should be noted that although this specification describes the embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
