[0002] With the rapid development of modern industry and communication technology, high-frequency multi-strand cables are increasingly widely used in various fields, such as power transmission, communication networks, and aerospace. These cables need to withstand various complex mechanical stresses in actual use, and the tensile strength of the cables during tensile testing limits the testing range. Current methods involve manual testing of the cable surface tensile strength, but these methods suffer from low accuracy and poor testing results. Furthermore, the human application of force makes it difficult to determine the magnitude of the force applied to the cable each time, which can affect the measurement results. Additionally, most tensile tests are performed from both ends, resulting in a single testing method and relatively limited data. Summary of the Invention

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0016] Please see Figure 1-2This application provides a technical solution: a high-frequency multi-strand cable tensile strength testing device, including a main support 15, a worktable 4 is provided at the upper end of the main support 15, transverse slide rails 5 are provided on both sides of the upper surface of the worktable 4, a cross brace 17 is provided at the upper end of the transverse slide rails 5, a vertical support plate 2 is provided on the upper surface of the cross brace 17, a screw adjusting seat 1 is provided on the vertical support plate 2, and a cable pull rope 3 is connected to the movable ends of the two screw adjusting seats 1.

[0017] The main support 15 is the basic structure of the entire testing device, ensuring the stability and safety of the overall device.

[0018] The workbench 4 is located at the top of the main support 15, providing a work platform on which various components required for testing are installed.

[0019] The transverse slide rails 5 are located on both sides of the workbench 4; allowing the cross brace 17 to move laterally, thereby enabling the adjustment of the position of the cable pull rope 3 to accommodate different types of cable testing needs.

[0020] The cross brace 17 is located on the horizontal slide rail 5; it can move freely in the horizontal direction through the slide rail system to support the vertical support plate 2 and related components such as the lead screw adjustment seat 1, so that these components can move together with the cross brace 17.

[0021] The vertical support plate 2 is fixed to the upper surface of the horizontal support bracket 17; providing an installation position for the lead screw adjusting seat 1.

[0022] The lead screw adjusting seat 1 adjusts its position up and down by rotating the lead screw, thereby changing the vertical height of the cable pull rope 3; this allows different tensile forces to be applied to the cable to meet the requirements under different test conditions.

[0023] Two lead screw adjustment seats 1 are located at both ends of the vertical support plate 2, and their movable ends are connected by cable pull rope 3, which work together on the cable. The two lead screw adjustment seats 1 operate synchronously, thereby ensuring the uniformity of the tension.

[0024] The two ends of the cable pull rope 3 are respectively connected to the movable ends of the two lead screw adjustment seats 1.

[0025] The cable under test is located between the cable pull ropes 3, and the tension applied to the cable is controlled by adjusting the position of the lead screw adjustment seat 1.

[0026] This structure allows for flexible adjustment of the cable's stress conditions, making it suitable for precise tensile performance testing of cables of various sizes and types. Through the coordinated operation of its components, it can simulate various stress states that the cable might encounter under actual usage conditions, thereby comprehensively evaluating the cable's quality and performance.

[0027] The workbench 4 is provided with cylinder holders 14 on both sides, and telescopic cylinders 6 are provided on the cylinder holders 14. The output end of the telescopic cylinders 6 is connected to a pressure detector 10. The main support 15 is provided with a sliding guide on one side, and a cross brace 18 is provided on the sliding guide. A connecting side bracket 8 and a cable holder 16 are provided on one side of the cross brace 18. The connecting side bracket 8 is connected to the pressure detector 10.

[0028] The cylinder holder 14 provides a stable mounting base for the telescopic cylinder 6. The cylinder holder 14 ensures that the telescopic cylinder 6 can be firmly fixed to the worktable and can be adjusted or replaced as needed.

[0029] The telescopic cylinder 6 extends or retracts the piston rod via hydraulic or pneumatic pressure, thereby applying a predetermined pressure to the cable; it is used to simulate various stress conditions that the cable may experience in actual use.

[0030] Pressure detector 10 is located at the output end of telescopic cylinder 6. It monitors and records the specific pressure value applied to the cable by telescopic cylinder 6 in real time. This helps to accurately evaluate the cable's performance under different load conditions.

[0031] The sliding guide allows the cross brace side frame 18 to move vertically to accommodate testing needs at different heights. This increases the flexibility of the device, enabling it to handle a wider range of cable sizes and types.

[0032] The connecting side bracket 8 is located on one side of the cross brace side frame 18, connecting the pressure detector 10 to the cable holder 16 to form a complete force transmission link. When the telescopic cylinder 6 applies force, this chain will effectively transmit the force to the cable under test.

[0033] The cable holder 16 secures the other end of the cable under test (relative to the end secured by the cable pull cord 3). The cable holder 16 ensures that the cable will not slip or suffer other forms of damage during testing.

[0034] Furthermore, the sliding guide includes a vertical sliding mounting plate 11 and a vertical sliding guide rail 9. The vertical sliding mounting plate 11 is vertically disposed on the lower surface of the workbench 4, and the vertical sliding guide rail 9 is slidably connected to the vertical sliding mounting plate 11.

[0035] The sliding guide allows the cross brace 18 and the components connected thereto (such as the cable holder 16) to move in the vertical direction; this increases the flexibility of the device and allows for precise adjustment for cables of different heights and lengths.

[0036] A vertical sliding mounting plate 11 is vertically mounted on the lower surface of the worktable 4, providing a support structure for the sliding guide rail 9. This ensures that the guide rail can be securely installed and remain vertical.

[0037] The vertical sliding guide rail 9 is connected to the vertical sliding mounting plate 11, ensuring that the vertical sliding guide rail 9 is securely installed on the vertical sliding mounting plate 11, providing a smooth and precise vertical movement path for the cross brace side frame 18. By adjusting the position of the cross brace side frame 18, the height of the cable holder 16 can be changed, thereby adjusting the cable tension or applying different forces.

[0038] Furthermore, the upper surface of the workbench 4 is provided with an intermediate support guide 12, and the upper surface of the intermediate support guide 12 is provided with a cable guide wheel 7.

[0039] The intermediate support guide 12 is located on the upper surface of the worktable 4, providing a stable support point to support the cable guide roller 7. The cable guide roller 7, mounted on the upper surface of the intermediate support guide 12, guides the cable smoothly through the test area, reducing friction and preventing unnecessary wear on the cable; ensuring the cable stays on the correct path during testing, avoiding sagging or deviation due to gravity or other external forces. The rotational motion helps disperse stress on the cable, especially when tension is applied, allowing for a more even distribution of force.

[0040] Furthermore, an auxiliary support frame 13 is provided on the edge of the workbench 4, and a cable guide wheel 7 is also provided on the auxiliary support frame 13.

[0041] The auxiliary support 13 is set at the edge of the workbench 4 to provide additional support points, prevent the edge of the workbench 4 from damaging the cable sheath, provide additional support, increase the overall rigidity of the system, help reduce vibration and unnecessary bending, provide an installation position for the cable guide wheel 7, and ensure smooth movement of the cable throughout the path.

[0042] Furthermore, a transverse drive assembly is provided on both sides of the worktable 4, and the sliding end of the transverse drive assembly is connected to the connecting assembly provided on the lower surface of both sides of the cross brace 17.

[0043] The lateral drive assembly provides power, enabling the cross brace 17 to move smoothly and precisely on the lateral slide rail 5.

[0044] By controlling the speed and direction of the motor, the position of the cross brace 17 can be precisely adjusted.

[0045] The automation level of the testing equipment has been increased, the need for manual adjustments has been reduced, and testing efficiency has been improved.

[0046] The connecting group is located on the lower surfaces of both sides of the cross brace 17.

[0047] It is connected to the sliding end of the transverse drive assembly to ensure that the cross brace 17 can move with the movement of the drive assembly.

[0048] This ensures the stability and consistency of the cross brace 17 during movement, preventing deviation or jamming.

[0049] Furthermore, a movable assembly 19 is provided around the lower end of the main support 15.

[0050] The mobile unit 19 allows the entire test setup to be easily moved in workshops, laboratories or other working environments, facilitating changes in test locations as needed.

[0051] Once the equipment is in place, its position can be secured by locking the wheels or adjusting the support feet to ensure stability during testing and prevent accidental movement.

[0052] The casters feature an adjustable height design, which helps adapt to uneven ground and ensures that the work surface 4 is level, thereby improving the accuracy of test results.

[0053] Furthermore, the cylinder holder 14 has a slot structure in the middle, which is engaged with the worktable surface 4 and connected by fasteners.

[0054] The cylinder holder 14 has a slot in the middle part, which is used to engage with the corresponding structure on the worktable 4 to securely fix the cylinder holder 14 to the worktable 4.

[0055] The slot structure allows the cylinder holder 14 to be quickly positioned and snapped onto the worktable 4, simplifying the installation process. The slot structure provides initial fixation, preventing displacement of the cylinder holder 14 before it is fully tightened.

[0056] The use of fasteners facilitates subsequent adjustments and maintenance. If the cylinder caliper 14 needs to be replaced or repositioned, it can be easily disassembled and reinstalled.

[0057] When in use: Use the moving group 19 to move the entire device to the appropriate position. If the ground is uneven, adjust the height of the casters to ensure that the worktable 4 is level; lock the wheels in the moving assembly 19 to prevent movement during the test; align the cylinder holder 14 with the slot structure on the worktable 4 and gently push it in until it is fully locked; tighten the cylinder holder 14 with fasteners (such as bolts and nuts) to the specified torque value to ensure that the cylinder holder 14 is firmly fixed; fix one end of the cable to be tested to the cable pull rope 3; pass the cable through the cable guide wheel 7 on the intermediate support guide 12 and the auxiliary support 13 to ensure that the cable is naturally straight and without twisting, and is in a taut state; fix both ends of the cable to the cable holder 16, turn on the test control software or system, set the test parameters, such as the applied pressure and test time, and gradually increase the tension through the telescopic cylinder 6, while monitoring and recording the data of the pressure detector 10, observing the pressure value displayed by the pressure detector 10 in real time, ensuring that the applied pressure meets the expectations, and recording various data during the test, including the tension change curve and the deformation of the cable, etc. When the preset test conditions or time are reached, stop applying the tension.

[0058] When testing is required at other locations along the cable, ensure the cable is on the cable guide wheel 7. Then, activate the transverse drive assembly to move the cross brace 17 along the transverse slide rail 5 to the predetermined position. Confirm the cross brace 17 is accurately positioned and locked. Adjust the height of the cable pull rope 3 by rotating the lead screw adjusting seat 1, and then test the cable. The lead screw adjusting seat 1 continues to move, and the pressure sensor 10 on the cable pull rope 3 detects the pressure data applied to the cable. When the preset test conditions or time are reached, the cable pull rope 3 stops operating. Release the cable pull rope 3 and the cable holder 16, remove the cable to be tested, check for damage or other abnormalities, and record the results.

[0059] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
