Description

Technical Field

[0001] The present invention relates to the technical field of cable tensile property detection, and specifically to a cable tensile property detection device. Background Art

[0002] It is crucial to detect the tensile property of cables. In actual use, cables are faced with various tensile challenges. For example, during overhead power transmission, they have to bear their own gravity, wind force, and ice and snow loads, and may be frequently dragged in industrial equipment. If the tensile property fails to meet the standard, the cable is likely to break, which will not only lead to power interruption, affecting production and life, but also may cause safety accidents. Moreover, if the internal structure of the cable is damaged when being pulled, its insulation performance will be reduced, the resistance will increase, and the service life will be shortened. Different environments have different requirements for the tensile property of cables, and cables with high tensile performance are more needed in special environments such as mines and deep seas. In addition, the tensile property detection is also a key means for cable manufacturers to control quality and improve processes, which can ensure product quality and maintain the enterprise's reputation.

[0003] In the existing cable tensile property detection process, the existing detection devices are difficult to adapt to the tensile property detection of cables with different lengths. The structures of many traditional devices are fixed, and the distance between the components on both sides for fixing the cable cannot be adjusted flexibly. This results in that when detecting cables with different lengths, either the cable cannot be correctly installed and fixed, or the force on the cable is uneven during the detection process, affecting the accuracy of the detection results. For example, for a longer cable, the traditional device may not be able to provide a sufficient tensile force range, making the cable unable to fully display its tensile property during the tensile process; while for a shorter cable, it may not be effectively fixed due to the excessive distance between the fixing components.

[0004] When some structures fail, traditional devices often need to be shut down as a whole for maintenance or component replacement, with complex operations and long time consumption. Moreover, due to the unreasonable connection method between components, replacing components may affect the normal operation of other components, further reducing the stability of the device;

[0005] For the detection of cables with different diameters, the adaptability of existing equipment is poor. The cable locking structure of traditional detection devices is usually relatively single and cannot effectively lock cables with different diameters. This leads to the situation that when detecting cables of different specifications, the cable may not be firmly fixed, and the cable is likely to slide under the action of tensile force, thus affecting the reliability of the detection results.

[0006] In summary, there are many defects in the existing cable tensile performance detection process in terms of applicability, maintainability, adaptability to different cable specifications, and operation convenience. To overcome these problems and improve the quality and efficiency of cable tensile performance detection, it is imperative to design a "cable tensile performance detection device", which can effectively solve the deficiencies in the existing detection process and provide a more reliable, efficient, and convenient solution for cable tensile performance detection.

[0025] 2.

[0054] Embodiment 3

[0055] Refer to Figure 1 、 Figure 7 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 On the basis of Embodiment 1 and Embodiment 2, it is further obtained that the replacement mechanism 3 includes a combination component 31 and a fixing component 32.

A positioning card rod 3204 is fixedly connected to the bottom of the threaded rod 3203, and the positioning card rod 3204 is clamped inside the bottom of the splicing pressing block 3101.

[0057] Further: A plurality of splicing blocks 3101 are arranged successively from small to large below the lower pressing block 2304. Workers can select splicing blocks 3101 of different sizes for installation according to the different diameters of the cable under test. When the splicing block 3101 moves downward to cooperate with the V-shaped clamping seat 2302 to lock the cable, the contact area with the outer surface of the cable can be increased as much as possible, the structural strength after the cable is locked is improved, and the adaptability during the use of the device is improved.

[0058] During the actual operation process, when the tensile performance of the cable needs to be tested, the worker first places the cable in the V-shaped clamping seats 2302 on the left and right sides to keep the cable straight. Then the worker starts a plurality of synchronous motors 2401. The synchronous motors 2401 start to drive the second threaded rotating shaft 2402 to rotate. The rotation of the second threaded rotating shaft 2402 drives the slider 2305 to move downward through the threaded barrel 2403. The downward movement of the slider 2305 drives the splicing block 3101 to move downward through the lower pressing block 2304. The downward movement of the splicing block 3101 cooperates with the V-shaped clamping seat 2302 to complete the clamping and locking of the cable until the splicing block 3101 of the device can no longer move downward. At this time, the locking process of the left and right sides of the cable is completed. Then the worker starts the driving motor 1103. The driving motor 1103 starts to drive the first threaded rotating shaft 1104 to rotate. The rotation of the first threaded rotating shaft 1104 drives the lifting plate 1202 to move upward through the lifting threaded barrel 1201. The upward movement of the lifting plate 1202 drives the fixed shaft 1301 to move upward. The upward movement of the fixed shaft 1301 drives the left and right connecting frames 1303 to move outward synchronously through the connecting arm 1302. The outward movement of the connecting frame 1303 drives the moving seat 1404 to move outward through the sliding barrel 1401 and the fixed frame 1403. The outward movement of the moving seat 1404 drives the base 2101 to move outward. The outward movement of the base 2101 drives the two ends of the locked cable to move outward synchronously. At this time, the bases 2101 on the left and right sides move outward to apply opposite tensile forces to the cable. Then the worker gradually increases the output torque of the driving motor 1103 until the cable breaks. Then the worker can calculate the tensile performance of the cable according to the output torque when the cable breaks.

[0059] When it is necessary to replace the splicing pressing block 3101, the staff first determines the position of the splicing pressing block 3101 to be retained, then supports the splicing pressing block 3101 to be retained, and then rotates the torsion ring 3202. The rotation of the torsion ring 3202 drives the rotation of the threaded barrel 3201, and the rotation of the threaded barrel 3201 drives the threaded rod 3203 to move downward. The threaded rod 3203 moves downward and disengages from the connection with the threaded barrel 3201. At this time, the threaded rod 3203 loses support after disengaging from the connection with the threaded barrel 3201. Then, the splicing pressing block 3101 located below the splicing pressing block 3101 to be retained will synchronously drop downward under the action of gravity with the threaded rod 3203. Then, the staff removes the threaded rod 3203 and reinserts it into the bottom of the splicing pressing block 3101 so that the top of the threaded rod 3203 contacts the bottom of the threaded barrel 3201. Then, the torsion ring 3202 is rotated again. At this time, the rotation of the torsion ring 3202 drives the threaded rod 3203 to move upward in the inner circle of the threaded barrel 3201. The upward movement of the threaded rod 3203 drives the positioning rod 3204 to move upward, and the positioning rod 3204 moves upward and is clamped into the bottom of the splicing pressing block 3101 until the torsion ring 3202 can no longer rotate. At this time, the size replacement of the splicing pressing block 3101 is completed.
