Embodiment Construction
[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0025] like figure 1 , figure 2 As shown, the test device of the present invention includes a front vehicle 1, a rear vehicle 11, a cable communication tester 2, a computer 4, a tensile force gauge 8 and an overall test cable 9, wherein the rear of the front vehicle 1 is installed with a front vehicle rear tow hook 6. The head of the rear vehicle 11 is installed with the rear trailer hook 12, one end of the tension gauge 8 is connected with the rear trailer hook 6 of the front vehicle through the shackle 7, and the other end is connected with one end of the test cable as a whole 9. Test The other end of the whole cable 9 is connected to the front tow hook 12 of the rear vehicle, and the tension gauge 8 is electrically connected to the computer 4 on the front vehicle 1 through the communication line B5.

The invention belongs to the field of mechanical testing, and particularly relates to a testing device for instant tension of a cable and a testing method of the testing device. The testing device is characterized in that a front buckle and a rear buckle are arranged at the two ends of the testing cable by capels, cable binding heads and cable clamping devices; a testing connection line is reserved at the front buckle; one end of a tension meter is connected with a rear trailer hook of a front vehicle by a shackle; the other end of the tension meter is connected with the front buckle of the testing cable; the tension meter is connected with a computer by a communication line; the testing connection line of the testing cable is connected with a cable communication tester; a safety rope is longer than the testing cable, and bound on the testing cable by binding tapes; and the two ends of the safety rope are tightened on a front trailer hook and the rear trailer hook of the front vehicle and a rear vehicle. The testing method comprises the steps that different braking degrees are selected for the rear vehicle; the front vehicle instantly pulls the rear vehicle to accelerate forwards at different speeds by the testing cable; tension testing data of the tension meter is recorded by the computer; and on-off of the cable is recorded by the cable communication tester. The testing device has the advantage of simple structure. The testing method has the advantages of easiness in realization, testing safety and the like.
Description
technical field [0001] The invention belongs to the field of mechanical testing, in particular to a cable instantaneous tensile force testing device and a testing method thereof. Background technique [0002] Most of the existing cable tensile testers are short-range (generally no more than 1 m) tensile test, and seldom can perform fast tensile testing. However, the actual situation is that there is often an instant tension start. For example, when the submarine is deployed at sea, the top floating ball is first thrown to the sea, the cables are laid out in turn, and finally the anchor at the bottom is thrown into the sea. , the weight falls at an accelerated rate, and finally falls at a uniform speed. When the float drops to a certain depth and is about to enter the water, the cable will be instantly subjected to a large tensile force; and the breaking force of the cable will be quite different when the cable is pulled quickly and slowly.
