Testing device for instant tension of cable and testing method of testing device

Abstract

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 instant tension testing device and a testing method thereof. Background technique [0002] Most of the existing cable pull testers are short-distance (generally no more than 1m) pull test, and few can perform fast pull test. However, the actual situation is that there is often a situation where the pull force is activated instantaneously. For example, when deploying a submersible buoy at sea, first throw the uppermost floating ball onto the sea surface, then spread out the cables in turn, and finally throw the anchor weight at the bottom into the sea. , the weight accelerates to fall, and finally falls at a constant speed. When the floating ball descends to a certain depth and is about to enter the water, the cable will be subjected to a larger pulling force instantly; and, the breaking force of the cable will be quite different under the condition of fast pulling and s...
