Description

Technical Field

[0001] This utility model relates to the field of cable vertical winding technology, specifically a cable vertical winding testing machine. Background Technology

[0002] The vertical cable winding test is an important test used to evaluate the performance of cables under specific bending and mechanical stress conditions. This test requires the cable sample to be accurately mounted on the testing equipment. Clamping clamps can firmly hold one end of the cable or a specific position, fixing it to the vertical test frame or other related devices. This ensures that the cable does not shift or shake during winding, allowing it to be wound in a predetermined manner and path. This ensures the test is conducted under stable conditions, thereby guaranteeing the accuracy and reliability of the test results.

[0003] If the clamping force of the pliers is insufficient, the sample may loosen or slip out of the pliers during the cable winding process. This will prevent the cable from being wound in the intended manner, making the test process impossible and compromising the accuracy and reliability of the test results.

[0004] Excessive clamping force may damage the cable sheath and insulation. The jaws of a pliers may squeeze the cable, causing sheath cracking, insulation deformation, and even damage to the internal conductor. This damage is not caused by the stress of the winding test itself and can interfere with the judgment of the cable's true performance. Therefore, this application provides a vertical cable winding test machine. Utility Model Content

[0014] As a further improvement of this utility model, a protrusion is provided on the side of the plate near the frame, and a positioning hole is provided in the middle of the protrusion. The positioning hole is fixed to one side of the frame by fasteners.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes the elastic plate and arc-shaped block design of the fixed terminal to adaptively adjust the clamping force according to the cable's outer diameter, evenly distributing pressure to avoid cable damage and increasing friction to prevent cable displacement or loosening during winding. The screw ring is compatible with the fixed terminal for further precise fixation, ensuring the cable remains in a stable position during testing and guaranteeing accurate and reliable test results.

[0031] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0032] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0033] Please see Figure 1-9 In vertical cable winding tests, clamps play an indispensable role. They firmly clamp one end of the cable or a specific position, fixing the cable to the vertical test frame or other related equipment. This fixing function effectively prevents the cable from shifting or shaking during winding, ensuring that the cable is wound in the predetermined manner and path. This allows the test to be conducted under stable conditions, thus ensuring the accuracy and reliability of the test results and providing data that truly reflects the cable's performance. If the clamping force of the clamps is insufficient, the cable sample may loosen or slip out of the clamps during winding. Once this happens, the cable cannot be wound in the predetermined manner, the test process cannot be carried out normally, and the final test results will lose accuracy and reliability, failing to provide us with effective data support.

[0034] Excessive clamping force from pliers can damage cables. The jaws may squeeze the cable, causing sheath rupture, insulation deformation, and even damage to the internal conductors. These damages are not caused by the stress of the winding test itself, and they interfere with our judgment of the cable's true performance, preventing us from accurately assessing the cable's performance under normal test conditions. Therefore, this application provides a cable vertical winding test machine, including a support frame 1 for support and winding reels 2 disposed on top and below the support frame 1, with a cable 3 wound between the two winding reels 2.

[0035] Both ends of the cable 3 are connected to fixed terminals 5, which are inserted into the fixed frame 4 to achieve the vertical test of the cable 3;

[0036] The fixed terminal 5 includes a cylindrical body 55. One or more elastic plates 51 arranged in a circular array are provided at the bottom of the cylindrical body 55. The multiple elastic plates 51 are arranged at a preset tilt angle to form a clamping area 56 for clamping the cable.

[0037] The support frame 1 is made of high-strength metal materials, such as stainless steel or aluminum alloy, to ensure stable support of the entire device during testing. Its bottom is designed with adjustable support feet, allowing for fine-tuning according to different ground conditions to ensure the entire testing machine remains level and prevent uneven stress on the cable 3 due to tilting.

[0038] The winding reel 2 is driven by a motor, which is installed inside the support frame 1 and connected to the winding reel 2 via belt drive or gear drive. The surface of the winding reel 2 is specially treated to have a certain roughness to increase the friction between it and the cable 3 and prevent the cable 3 from slipping during winding. At the same time, the diameter and width of the winding reel 2 can be customized according to different specifications of cables 3 to meet various testing requirements.

[0039] The cylindrical body 55 of the fixed terminal 5 is made of high-strength plastic or metal material and is hollow inside to accommodate the end of the cable 3. The inner wall of the cylindrical body 55 is smooth to reduce wear on the cable 3. An opening is provided at the top of the cylindrical body 55 for easy insertion of the cable 3.

[0040] The elastic plate 51 is made of a metal material with good elasticity, such as spring steel. The surface of each elastic plate 51 is polished to reduce friction with the cable 3. The preset tilt angle of the elastic plate 51 is optimized according to the outer diameter and material of the cable 3. When the cable 3 is inserted into the clamping area 56, the elastic plate 51 will elastically deform, tightly clamping the cable 3 and providing a suitable clamping force.

[0041] The mounting bracket 4 is installed on the support frame 1, and its height can be adjusted according to the test requirements. The mounting bracket 4 is provided with slots that match the fixing terminals 5. The inner wall of the slots is lined with rubber pads to increase friction between the fixing terminals 5 and the mounting bracket 4, ensuring that the fixing terminals 5 are securely inserted into the mounting bracket 4. Simultaneously, the mounting bracket 4 is also equipped with locking devices, such as bolts or clips, to further secure the fixing terminals 5 and prevent them from loosening during the test.

[0042] The testing machine is equipped with an advanced control system that can precisely control the speed, direction, and number of turns of the winding reel 2. The control system uses a programmable logic controller (PLC), allowing operators to input test parameters such as winding speed and number of turns via a touchscreen. Simultaneously, the control system is also equipped with sensors that can monitor parameters such as the tension and temperature of the cable 3 in real time, and feed the data back to the operator for timely adjustments to the test parameters.

[0043] The design of the elastic plate 51 of the fixed terminal 5 can automatically adjust the clamping force according to the outer diameter of the cable 3, avoiding the problem of excessive or insufficient clamping force of traditional iron plate clamps. The appropriate clamping force ensures that the cable 3 will not be displaced or shaken during the winding process, so that the cable 3 can be wound in a predetermined manner and path, thereby improving the accuracy and reliability of the test results.

[0044] The control system can precisely control the rotation speed, direction, and number of turns of the winding reel 2, as well as monitor parameters such as the tension and temperature of the cable 3 in real time, providing stable test conditions and further improving the accuracy of the test results.

[0045] The surface of the elastic plate 51 is polished to reduce friction with the cable 3 and avoid damage to the cable 3's sheath and insulation. At the same time, the appropriate clamping force will not compress the conductor inside the cable 3, ensuring the integrity of the cable 3 and enabling the test results to truly reflect the performance of the cable 3.

[0046] The plug-in design of the fixed terminal 5 makes the installation and removal of the cable 3 very convenient. The operator only needs to insert the fixed terminal 5 into the slot of the mounting bracket 4 and fix it with the locking device. At the same time, the touch screen operation interface of the control system is simple and easy to understand, reducing the technical requirements of the operator and improving the efficiency of the test.

[0047] The diameter and width of the winding reel 2 can be customized according to different specifications of cables 3, and the elastic plate 51 of the fixed terminal 5 can also adapt to cables 3 with different outer diameters. In addition, the adjustable support feet of the support frame 1 and the height adjustment function of the fixed frame 4 enable the testing machine to adapt to different testing environments and testing requirements, and have strong applicability.

[0048] An installation area 52 is provided on the inner side of the cylinder 55. One or more sets of arc-shaped blocks 54 are arranged in a ring on the inner wall of the installation area 52 for clamping the end of the cable.

[0049] A circular plate 53 is provided on the top of the cylinder 55. The circular plate 53 is adapted to the fixing frame 4 and is used to restrict the fixing terminal 5.

[0050] The fixing frame 4 includes a frame body 42, and a support plate 43 is provided on one side of the frame body 42. The support plate 43 is fixed on the side of the frame body 42 by fasteners 41.

[0051] The arc-shaped block 54 on the inner wall of the mounting area 52 of the cylinder 55 is made of rubber. Rubber has good elasticity and friction, which can better clamp the end of the cable 3. The surface of the arc-shaped block 54 is frosted to further increase the friction with the cable 3.

[0052] The arc-shaped blocks 54 are set in multiple groups, with each group consisting of three arc-shaped blocks 54 evenly distributed in a ring. The curvature of the arc-shaped blocks 54 matches the outer diameter of the cable 3. When the cable 3 is inserted into the installation area 52, the arc-shaped blocks 54 can fit tightly against the surface of the cable 3, providing a stable clamping force. At the same time, the thickness and elasticity of the arc-shaped blocks 54 can be adjusted according to the material and outer diameter of different cables 3 to accommodate various types of cables 3.

[0053] The circular plate 53 is integrally formed with the cylinder 55 and is made of the same engineering plastic material as the cylinder 55. The diameter of the circular plate 53 is slightly larger than the outer diameter of the cylinder 55, and its edges are chamfered to prevent scratching the operator during operation. The surface of the circular plate 53 is provided with anti-slip texture to facilitate the operator's handling and installation.

[0054] The circular plate 53 and the fixing frame 4 can be connected by a slot 436. The fixing frame 4 is provided with an annular slot 436 that matches the circular plate 53. The circular plate 53 can be accurately embedded in the slot 436 to restrict the fixing terminal 5 and prevent it from shaking or falling off during the test.

[0055] The frame 42 is made of high-strength metal materials, such as stainless steel, and is welded and processed. The frame structure of 42 is designed as a frame, providing excellent stability and load-bearing capacity. The surface of 42 undergoes anti-corrosion treatment, such as galvanizing or spraying with anti-corrosion paint, to extend its service life.

[0056] The frame 42 is fixed to the support frame 1 with bolts. The specifications and number of bolts are selected according to the size and load-bearing capacity of the frame 42. During installation, a level is used to ensure that the frame 42 is horizontal to ensure the accuracy of the cable 3 in the vertical winding test.

[0057] The support plate 43 is made of aluminum alloy, which is lightweight and high-strength. The support plate 43 is rectangular in shape, and its length and width are designed according to the length and diameter of the cable 3, which can effectively support the cable 3 and prevent the cable 3 from sagging during the winding process.

[0058] The support plate 43 is secured to the side of the frame 42 by two high-strength bolts as fasteners 41. The bolt heads are equipped with anti-loosening washers to prevent the bolts from loosening during the test. At the same time, the tightening torque of the bolts can be adjusted according to the load-bearing capacity of the support plate 43 to ensure a firm and reliable connection between the support plate 43 and the frame 42.

[0059] The arc-shaped block 54 on the inner wall of the installation area 52 can adaptively adjust the clamping force according to the outer diameter of the cable 3. Compared with traditional iron plate clamps, it can distribute the clamping force more evenly, avoid causing local damage to the cable 3, better protect the sheath and insulation layer of the cable 3, ensure the integrity of the cable 3 during the test, and thus make the test results more accurately reflect the performance of the cable 3.

[0060] The arc-shaped block 54 is made of rubber and has been frosted, which increases the friction with the cable 3 and further improves the clamping stability of the cable 3 end, effectively preventing the cable 3 from shifting or loosening during the winding process, and ensuring the smooth progress of the test.

[0061] The slot 436 fitting method between the circular plate 53 and the fixing bracket 4 provides reliable restraint for the fixing terminal 5, ensuring its stable position during the test and preventing it from shaking or falling off due to vibration or external force during winding, thus improving the reliability and accuracy of the test. At the same time, the anti-slip texture on the surface of the circular plate 53 facilitates installation and disassembly operations for operators, improving work efficiency.

[0062] The frame 42 is made of high-strength stainless steel and has a frame structure design, which has good stability and load-bearing capacity. It can withstand the tensile and impact forces generated by the cable 3 during the winding process, ensuring the stable operation of the entire test device.

[0063] The support plate 43 effectively solves the problem of cable 3 sagging during winding, allowing cable 3 to be wound in a predetermined manner and path, thus improving the accuracy of the test. At the same time, the support plate 43 is fixed with high-strength bolts, ensuring a firm and reliable connection and further enhancing the stability of the mounting bracket 4.

[0064] The support plate 43 includes a plate body 431, both ends of which extend outward and are vertically arranged. A locking area 434 is provided at the vertical extension of the plate body 431. A ring-shaped locking groove 436 is provided at the locking area 434, and a screw ring 435 is installed at the locking groove 436.

[0065] The screw ring 435 has a through hole in the middle that is adapted to the fixed terminal 5 for fixing the fixed terminal 5.

[0066] A protrusion 432 is provided on the side of the plate 431 near the frame 42. A positioning hole 433 is provided in the middle of the protrusion 432. The positioning hole 433 is fixed to one side of the frame 42 by fastener 41.

[0067] The plate 431 is made of high-strength aluminum alloy, which can reduce the weight of the testing machine while ensuring the overall strength of the support plate 43.

[0068] The portions of the plate 431 that extend vertically outward at both ends are manufactured using a one-piece molding process to ensure structural stability. The dimensions of the engaging area 434 are precisely designed to fit the outer diameter of the threaded ring 435. The slots 436 are evenly distributed in a ring within the engaging area 434, and their depth and width are precisely machined according to the dimensions of the threaded ring 435 to ensure that the threaded ring 435 can be tightly installed within the slots 436.

[0069] The surface of the slot 436 is finely ground and polished to reduce the friction between it and the screw ring 435, making it easier to install and remove the screw ring 435. At the same time, in order to improve the wear resistance and corrosion resistance of the slot 436, its surface can be anodized.

[0070] The screw ring 435 is made of stainless steel, such as 304 stainless steel, which has good corrosion resistance and mechanical properties. The inner diameter of the through hole in the middle of the screw ring 435 is matched with the outer diameter of the fixed terminal 5 to ensure accurate fixation of the fixed terminal 5.

[0071] The outer surface of the threaded ring 435 is threaded to match the thread in the slot 436. By rotating the threaded ring 435, it can be securely installed in the slot 436. The thread pitch and tooth profile are optimized to ensure sufficient tightening force and self-locking performance.

[0072] The bump 432 and the plate 431 are made of the same aluminum alloy material and are integrally formed with the plate 431 by casting or machining to ensure the connection strength between the bump 432 and the plate 431.

[0073] Fastener 41 is made of high-strength bolts to provide sufficient tightening force. During installation, use a torque wrench to tighten the bolts to the specified torque value to ensure a secure and reliable connection between the support plate 43 and the frame 42.

[0074] The through hole in the middle of the screw ring 435 is adapted to the fixed terminal 5, which can accurately fix the fixed terminal 5 and prevent the fixed terminal 5 from shaking or shifting during the test. This ensures that the cable 3 maintains a stable position during the vertical winding test, thereby improving the accuracy and reliability of the test results.

[0075] The screw ring 435 is connected to the support plate 43 via the slot 436. This connection method provides reliable fixing force and facilitates installation and disassembly. When it is necessary to replace the cable 3 or perform equipment maintenance, the screw ring 435 can be quickly removed from the slot 436, improving work efficiency.

[0076] The vertical extension design at both ends of the plate 431 increases the structural strength and stability of the support plate 43, enabling it to better withstand the weight of the cable 3 and the tensile force generated during winding. At the same time, the engaging area 434 and the slot 436 at the vertical extension provide precise positioning and reliable fixing for the installation of the screw ring 435.

[0077] The design of the protrusion 432 and the positioning hole 433 allows the support plate 43 to be firmly fixed to the frame 42 by the fastener 41. The positioning hole 433 ensures the accurate position of the support plate 43 during installation, and the high-strength bolts provide sufficient tightening force to prevent the support plate 43 from loosening or shifting during the test, thus ensuring the stability of the entire test device.

[0078] The design of the support plate 43 and the screw ring 435 can be adjusted according to different specifications of cables 3 and fixed terminals 5, making it highly adaptable. By replacing the screw ring 435 with different inner diameters or adjusting the size of the plate body 431, the vertical winding test requirements of various types of cables 3 can be met.

[0079] When the fixed terminal 5 is installed in the engagement area 434 and adapted to the screw ring 435, if a lot of pulling is required, both ends of the cable 3 can be clamped by the elastic plate 51. During rewinding, a uniform limiting force can be applied to the outside of the cable 3 to avoid problems with test accuracy.

[0080] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
