[0002] Cables are the core carriers of power transmission, communication and industrial equipment, and their mechanical properties are directly related to engineering safety and service life. Traditional cable tension test devices mostly use unidirectional tensile structures (such as uniaxial tensile machines) to measure breaking force or deformation by applying static or quasi-static loads in a single direction. However, in actual applications, cables are often in complex and changeable stress environments. The unidirectional test method has significant limitations and cannot simulate multi-dimensional composite stress scenarios in real working conditions, resulting in a large deviation between the test data and the actual failure mode.

[0019] 3. When the two sets of telescopic rods on the upper and lower sides rotate along the round rod, the pressure rod will be pressed to move downward, driving the four sets of push rods to move downward at the same time, compressing the four sets of return springs, and the driving work of the rotating rod is realized through the movement of the push rod, completing the purpose of automatic driving and improving the working efficiency of the equipment.

When the push wheel moves to the position of the cable, the arc sleeve is sleeved on the outside of the cable. When the cable tension tester is used for stretching, the upper and lower sides are synchronously sleeved on the outside of the cable to limit it, so as to avoid the stored elastic potential energy being released through swinging when the cable is broken, which may aggravate the dynamic impact effect and cause collision.

[0035] The threaded rod 613 is driven to rotate by the second motor 614, driving the two sets of connecting parts 612 to slide along the platform 63 and approach each other, pushing the two sets of telescopic rods 69 to slide along the two sets of round rods 611, and the two sets of telescopic rods 69 will push the push wheel 68 to move toward the cable 8. The cable 8 is pushed from the lateral side by the push wheel 68.

When the push wheel 68 moves to the position of the cable 8, the arc sleeve 73 is sleeved on the outside of the cable 8.

[0043] The tensile plate 3 is slidably arranged with the cable tensile testing machine 1. The clamp 4 is rotatably arranged with the upper plate 2. The rotating shaft of the first motor 5 is fixedly connected to the upper clamp 4.

[0046] S1: Clamp the cable 8 in the two clamps 4, perform the tensile test work through the cable tensile testing machine 1, and cooperate with the first motor 5 to drive the cable 8 to rotate, so that the clamped cable 8 generates torsion, increasing the composite tensile test with rotational torque;

[0047] S2: Drive two sets of telescopic rods 69 by the second motor 614 to push the push wheels 68 to reciprocally impact the side of the cable 8, thereby simulating the galloping of the conductor caused by wind. At the same time, the two sets of telescopic rods 69 press the pressure rod 712, and drive the movement of the push rod 711 to achieve the driving work of the rotating rod 78;

[0048] S3: When the push rod 711 moves downward, drive the rotating rod 78 to drive the limit strip 75 to move out of the arc groove 74. When cooperating with the cable tensile testing machine 1 for stretching work, the upper and lower sides are simultaneously sleeved outside the cable 8 to restrict it.

[0049] Working principle: During use, clamp the two ends of the cable 8 in the two sets of clamps 4 respectively. Drive the tension plate 3 and the installed clamps 4 to move through the cable tensile testing machine 1, thereby realizing the tensile test work on the cable 8. And drive the upper clamp 4 and the clamped cable 8 to perform a rotational movement through the first motor 5, so that the clamped cable 8 generates torsion. The composite tensile test that increases the rotational torque is not only a necessary means to conform to the actual situation, but also the core technology to improve the accuracy of cable reliability verification; in addition, drive the threaded rod 613 to rotate through the second motor 614, drive the two sets of connecting pieces 612 to slide along the platform 63 and approach each other, push the two sets of telescopic rods 69 to slide along the two sets of round rods 611, and the two sets of telescopic rods 69 will push the push wheels 68 to move towards the cable 8. Push the cable 8 from the lateral side through the push wheels 68. When the second motor 614 drives the threaded rod 613 forward and backward, the push wheels 68 can reciprocally impact the side of the cable 8, thereby simulating the galloping of the conductor caused by wind, and cooperate with the first motor 5 to drive to achieve periodic torsion and stretching, a composite stress scenario, breaking through the limitations of traditional unidirectional tensile testing; secondly, when the two sets of telescopic rods 69 on the upper and lower sides rotate along the round rods 611, they will press the pressure rod 712 to move downward, drive the four sets of push rods 711 to move downward simultaneously, compress the four sets of return springs 713, and achieve the driving work of the rotating rod 78 through the movement of the push rods 711, completing the purpose of automatic driving and improving the working efficiency of the equipment; and when the push rod 711 moves downward, the inclined push rod 711 will drive the rotating rod 78 to drive the guide rod 77 and the limit strip 75 to move along the arc groove 74, and move the two limit strips 75 in the arc groove 74 out. When the push wheel 68 moves to the position of the cable 8, cooperate with the arc sleeve 73 to be sleeved outside the cable 8. When cooperating with the cable tensile testing machine 1 for stretching work, the upper and lower sides are simultaneously sleeved outside the cable 8 to restrict it, avoiding that when the cable 8 is pulled off, the stored elastic potential energy is released through swinging, which may exacerbate the dynamic impact effect and cause impact.

Drive the cable (8) to rotate by cooperating with the first motor (5) to generate torsion on the clamped cable (8) and increase the composite tensile test of the rotation torque. S2: Drive the two groups of telescopic rods (69) through the second motor (614) to push the push wheels (68) to reciprocally impact the side of the cable (8), thereby simulating the galloping of the wire caused by the wind. At the same time, the two groups of telescopic rods (69) press the pressing rod (712) to drive the movement of the push rod (711) to realize the driving work of the rotating rod (78). S3: When the push rod (711) moves downward, drive the rotating rod (78) to drive the limiting strip (75) to move out of the arc-shaped groove (74). When cooperating with the cable tension testing machine (1) to perform the stretching work, the upper and lower sides are synchronously sleeved outside the cable (8) to limit it.
