First guide wheel, the second guide wheel, defect detecting device, in same level height detection, make the cable between the first guide wheel and the second guide wheel move linearly in the horizontal direction, are convenient to the detection of defect detecting device to cable; In addition, distance between the baffle plate of first and second reel is less than the twice of diameter, can ensure that the cable of every one deck on reel only has a circle, simplify the winding process of cable, also ensure that the cable of first volume winding apparatus, the first guide wheel, defect detecting device, the second guide wheel, volume Two winding apparatus is roughly in same plane, is convenient to the precision ensureing to detect.Certainly more suitably, the distance of the spaced surface that two the first baffle plates also can be made relative be the 1.05-1.5 of tested cable size doubly; The distance of the spaced surface that two second baffles are relative be the 1.05-1.5 of tested cable size doubly.
Diameter due to the cross-section of cable of the diverse location on qualified cable length direction should be identical, therefore in testing process, if cable is qualified, so the signal of 8 pressure transducers should be constant, its differential value relative to the time should be zero (can there is little deviation in reality in theory, close to zero), if but there is convex closure or depression in certain position, the signal of so corresponding pressure transducer can change, its differential value meeting offset from zero by a relatively large margin, therefore when measured value more than one in 8 pressure transducers is greater than setting threshold value relative to the absolute value of the differential of time, controller judges tested cable existing defects.
Other judgment mode can certainly be utilized, for qualified cable, because its diverse location diameter is identical, the decrement sum (this value is have corresponding relation with the diameter on this direction) of two relative springs should be within the specific limits, if there is convex closure or depression, so the decrement sum of two springs is certain to change, therefore controller can calculate the decrement of spring according to the signal of pressure transducer, when the decrement sum of relative two springs is greater than upper limit threshold or is less than lower threshold, controller judges tested cable existing defects.When calculating the decrement of spring according to force value, the gravity of spring can be considered; Also can select light spring, ignore the gravity of spring.Can according to the account form needing selection suitable of precision.
