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] In the fields of power and communications, cables serve as a crucial carrier for energy and signal transmission, and their quality and performance directly affect the safe and stable operation of the entire system. During actual use, cables are subjected not only to simple tensile forces but also often torsion and other complex stress conditions under tension. Therefore, comprehensive tensile and torsional performance testing of cables is essential.

[0003] Most existing cable tensile testing devices can only test the linear tensile force of cables, failing to simulate the torsional tensile force experienced in actual use. This leads to significant deviations between test results and real-world usage scenarios. Furthermore, when testing cables, especially larger diameter and heavier cables, the weight can cause sagging, further affecting accuracy. To overcome these shortcomings, this invention provides a cable tensile testing device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cable tensile testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cable tensile testing device, comprising a base, a protective plate fixedly connected to one side of the base, a rotating frame fixedly connected to the top of the base, a torsion component provided on the rotating frame, a first sliding groove provided at the top of the base, a first slider slidably connected to the first sliding groove, a tension component provided on the first sliding groove, a second sliding groove provided at the top of the first slider, and a tensile testing component provided on the second sliding groove.

[0006] Furthermore, a supporting rotating seat is fixedly connected to the middle of the top of the base, and a first rotating roller is rotatably connected to the supporting rotating seat.

[0007] Furthermore, the torsion assembly includes a rotating groove formed on the rotating frame, a second rotating roller rotatably connected to the rotating groove, a turntable provided on the second rotating roller, an insertion hole on one side of the turntable, a first electric hydraulic cylinder fixedly connected to one side of the turntable and on both sides of the insertion hole, a first clamping plate fixedly connected to the output end of the first electric hydraulic cylinder, a motor support frame fixedly connected to the top of the base and on one side of the rotating frame, a first reduction motor fixedly connected to the motor support frame, and the output end of the first reduction motor fixedly connected to one side of the turntable.

[0008] Furthermore, the stretching assembly includes a threaded rod rotatably connected to the first slide groove. A threaded hole is provided on one side of the first slider, and the threaded hole and the threaded rod are threadedly connected. A second reduction motor is fixedly connected to one side of the base, and the output end of the second reduction motor passes through the first slide groove and is fixedly connected to one end of the threaded rod.

[0009] Furthermore, the tensile force detection assembly includes a second slider that is slidably connected to the second slide groove. A second electric hydraulic cylinder is fixedly connected to the top of the second slider. A second clamping plate is fixedly connected to the output end of the second electric hydraulic cylinder. A cable detection body is fixedly connected to the top of the second slider and located on one side of the second slide groove. The detection end of the cable detection body is fixedly connected to one side of the second slider.

[0010] Furthermore, a control panel is fixedly connected to one side of the protective plate, and a PLC controller is fixedly connected to one side of the protective plate and below the control panel. The PLC controller and the control panel are electrically connected.

[0011] The beneficial effects of this utility model are:

[0012] In use, this invention uses a torsion assembly and a tensile testing assembly to torsion the cable during tensile testing, thereby verifying the change in tensile force under different torsion states. The cable is supported by a first rotating roller on the support rotating seat, preventing the heavy cable from sagging due to its own weight and affecting the test results. The first rotating roller also reduces the friction between the support frame and the cable during tensile testing, thus reducing the impact of friction on the cable tensile test.
