Description

Technical Field

[0001] This utility model relates to the field of cable tensile testing technology, and in particular to a cable tensile testing device. Background Technology

[0002] Cables are conductor systems used to transmit and distribute electrical energy, widely used in urban underground power grids, power plants, power supply for industrial and mining enterprises, and cross-water power transmission. Their core function is to ensure the safe and stable transmission of electricity, earning them the reputation of being the "blood vessels" and "nerves" of the national economy. During the cable manufacturing process, tensile testing devices are typically used to test the cable's tensile strength to facilitate its subsequent use.

[0003] When using a tensile testing device to test the tensile strength of a cable, the cable is usually clamped by a clamping mechanism and then pulled by a pushing mechanism to test the cable's tensile strength. However, existing clamping mechanisms typically use a threaded rod to drive a clamping plate to clamp the cable. The threaded rod lacks a limiting mechanism, which causes it to easily rotate, resulting in unstable cable clamping. At the same time, the existing pushing mechanism cannot be adjusted, which means that tensile strength testing can only be performed on cables of the same length, making it unsuitable for testing cables of different lengths and hindering cable testing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a cable tensile testing device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable tensile testing device includes a workbench. A mounting frame is installed on one side of the workbench via a moving mechanism. A pressure sensor is installed on the inner wall of the mounting frame via a pushing mechanism. Mounting blocks are fixedly installed on one side of the pressure sensor and on the top of the workbench. A first clamping plate is fixedly installed on one side of the mounting block. A second clamping plate and a mounting plate are installed on the top of the mounting block via a lifting mechanism. A mounting groove is formed on the surface of the mounting plate. A cylinder is fixedly installed on the top of the mounting block. A mounting column is installed on the inner wall of the cylinder via a reset mechanism.

[0007] Preferably, the moving mechanism includes a motor fixedly installed on one side of the workbench, a lead screw fixedly installed at the output end of the motor, a moving block threaded onto the surface of the lead screw, and the top of the moving block and the bottom of the mounting frame being fixedly installed.

[0008] Preferably, the pushing mechanism includes an electric push rod fixedly installed on the inner wall of the mounting frame, and a push plate is fixedly installed at the output end of the electric push rod. One side of the push plate and one side of the pressure sensor are fixedly installed.

[0010] Preferably, the reset mechanism includes a sliding column slidably mounted on the inner wall of the cylinder, a sliding plate fixedly mounted at one end of the sliding column, a spring fixedly mounted on the inner wall of the cylinder, one end of the spring and one side of the sliding plate being fixedly mounted, and one side of the sliding plate and one end of the mounting column being fixedly mounted.

[0012] Preferably, a second sliding groove is provided on one side of the mounting block, and the inner wall of the second sliding groove is in contact with the surface of the lifting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This cable tensile testing device, by placing both ends of the cable on the inner walls of two sets of first clamping plates, and using a reset mechanism to drive the mounting post away from the inner wall of the mounting groove, allows the second clamping plate to descend by rotating the threaded rod, thus clamping and fixing the cable through the first and second clamping plates. The reset mechanism also drives the mounting post to insert into the inner wall of the mounting groove, limiting the mounting plate and consequently limiting the threaded rod, preventing it from rotating and making the cable clamping and fixing more stable. A pushing mechanism moves the cable, and a pressure sensor detects the tensile force, allowing for the detection of cable tensile force. A moving mechanism moves the mounting block, adjusting the position of the mounting block on the right side, enabling testing of cables of different lengths.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Refer to Figure 1-4This utility model provides a technical solution: a cable tensile testing device, including a workbench 1. A mounting frame 5 is installed on one side of the workbench 1 via a moving mechanism. The moving mechanism includes a motor 2 fixedly installed on one side of the workbench 1. A lead screw 3 is fixedly installed at the output end of the motor 2. A moving block 4 is threaded onto the surface of the lead screw 3. The top of the moving block 4 and the bottom of the mounting frame 5 are fixedly installed to facilitate movement of the mounting frame 5. A first sliding groove 21 is provided on the top of the workbench 1. The inner wall of the first sliding groove 21 fits against the surface of the moving block 4, limiting the movement of the moving block 4 and making its movement more stable. A pressure sensor 8 is installed on the inner wall of the mounting frame 5 via a pushing mechanism. The pushing mechanism includes an electric push rod 6 fixedly installed on the inner wall of the mounting frame 5. A push plate 7 is fixedly installed at the output end of the electric push rod 6. One side of the push plate 7 and one side of the pressure sensor 8 are fixedly installed to facilitate movement of the pressure sensor. The pressure sensor 8 is moved. Mounting blocks 9 are fixedly installed on one side of the pressure sensor 8 and on the top of the workbench 1. A first clamping plate 10 is fixedly installed on one side of the mounting block 9. A second clamping plate 13 and a mounting plate 14 are installed on the top of the mounting block 9 via a lifting mechanism. The lifting mechanism includes a threaded rod 11 rotatably mounted on the top of the mounting block 9. A lifting block 12 is threadedly fitted onto the surface of the threaded rod 11. One side of the lifting block 12 and one side of the second clamping plate 13 are fixedly installed to facilitate the lifting and lowering of the second clamping plate 13. One end of the threaded rod 11 and one side of the mounting plate 14 are fixedly installed to facilitate the rotation of the mounting plate 14. A second sliding groove 22 is provided on one side of the mounting block 9. The inner wall of the second sliding groove 22 fits against the surface of the lifting block 12, limiting the lifting block 12 and making its lifting and lowering more stable. An mounting groove 15 is provided on the surface of the mounting plate 14. A cylinder 16 is fixedly installed on the top of the mounting block 9.

[0021] Specifically, the inner wall of the cylinder 16 is fitted with a mounting post 20 via a reset mechanism. The reset mechanism includes a sliding post 17 slidably mounted on the inner wall of the cylinder 16. A sliding plate 19 is fixedly mounted on one end of the sliding post 17. A spring 18 is fixedly mounted on the inner wall of the cylinder 16. One end of the spring 18 is fixedly mounted to one side of the sliding plate 19, and one side of the sliding plate 19 is fixedly mounted to one end of the mounting post 20. By placing both ends of the cable on the inner walls of the two sets of first clamping plates 10, the reset mechanism drives the mounting post 20 away from the inner wall of the mounting groove 15. Then, by rotating the threaded rod 11, the second clamping plate 13 is lowered, thereby clamping the cable between the first clamping plates 10 and the second clamping plate 13. The installation mechanism, through the reset mechanism, drives the mounting post 20 to insert into the inner wall of the mounting groove 15, thereby limiting the mounting plate 14 and the threaded rod 11, preventing the threaded rod 11 from rotating and making the cable clamping and fixing more stable. The cable is moved by the pushing mechanism, and the tension is detected by the pressure sensor 8. The position of the mounting block 9 on the right side can be adjusted by the moving mechanism, allowing for the detection of cables of different lengths. This achieves the purpose of facilitating the detection of the tension of cables of different lengths and facilitating the limiting of the threaded rod 11. The structure is simple and easy to use.

[0022] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0023] In use: When using this cable tensile testing device, by placing both ends of the cable on the inner walls of the two sets of first clamping plates 10, pulling the sliding column 17 moves the sliding plate 19. The sliding plate 19 moves the mounting column 20 away from the inner wall of the mounting groove 15. Then, by rotating the threaded rod 11, the lifting block 12 is lowered. The lifting block 12 moves the second clamping plate 13, thus clamping and fixing the cable through the first clamping plates 10 and the second clamping plate 13. Releasing the sliding column 17 allows the spring 18 to reset and move the sliding plate 19. The sliding plate 19 moves the mounting column 20, causing it to insert into the inner wall of the mounting groove 15. This limits the mounting plate 14, which in turn limits the threaded rod 11, preventing it from rotating and thus making the cable clamping and fixing more stable. The cable is moved by a push plate 7 driven by an electric push rod 6, which in turn moves a mounting block 9. The mounting block 9 then moves the cable, and a pressure sensor 8 detects the tension. After detection, the second clamping plate 13 is released by the threaded rod 11, allowing the cable to be removed. The lead screw 3 is rotated by a motor 2, which in turn moves a moving block 4. The moving block 4 then moves a mounting frame 5, which in turn moves the electric push rod 6. The electric push rod 6 then moves the mounting block 9, allowing the position of the mounting block 9 on the right side to be adjusted. This enables the detection of cables of different lengths, facilitating the detection of tension in cables of varying lengths and providing a convenient limit for the threaded rod 11. The structure is simple and easy to use.
