A kind of cable detecting device, comprises first volume winding apparatus, volume Two winding apparatus, the first guide wheel 1.3, second guide wheel 2.3, defect detecting device 3, display device, controller; Described first volume winding apparatus comprises the first support 1.2, the first rotating shaft be arranged on the first support, drive the first motor of the first rotating shaft, by first turn of shaft-driven first reel 1.1, described first reel 1.1 comprises the first cylindrical shell 1.1.2 and is positioned at the annular first baffle plate 1.1.1 of the first cylindrical shell both sides, and the distance of the spaced surface that two the first baffle plates are relative is less than 2 times of tested cable size; Described volume Two winding apparatus comprises the second support 2.2, setting the second rotating shaft on the secondary support bracket, drives the second motor of the second rotating shaft, by second turn of shaft-driven second reel 2.1, described second reel comprises the second cylindrical shell and is positioned at the annular second baffle of the second cylindrical shell both sides, and the distance of the spaced surface that two second baffles are relative is less than 2 times of tested cable size; Tested cable one end is fixed on first volume winding apparatus, and the other end is fixed on volume Two winding apparatus, and the cable between first volume winding apparatus and volume Two winding apparatus is through the first guide wheel 1.3, defect detecting device and the second guide wheel 2.3; Described defect detecting device comprises base plate, the column be positioned on base plate, the annular portion be positioned on column, 8 identical test sections are along the circumferential direction evenly provided with in described annular portion, test section comprise be positioned at pressure transducer 3.4 inside annular portion, one end is connected to Compress Spring 3.5, rolling wheel support 3.6, roller 3.7 on pressure transducer, the other end of Compress Spring is provided with rolling wheel support, rolling wheel support is provided with roller, and 8 rollers are connected to tested cable outside surface; During test, the length direction level of the tested cable between the first guide wheel and the second guide wheel; Described first motor, the second motor, 8 pressure transducers are connected with controller; Controller judges tested cable whether existing defects according to the signal of 8 pressure transducers.
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.
Described first motor and the second motor are servomotor, can certainly select stepper motor, or arrange scrambler on the first motor and the second motor, as long as the revolution that can record motor is just passable.When judging defect, the detection data of this defect of controller record, simultaneously according to the defect position in the cable that the revolution record of the first motor and/or the second motor detects.Such as, in tested cable walking process, somewhere has found defect, and this Time Controller just can calculate which position of this defect in cable length direction according to the revolution of motor.Only need, calculate the revolution of reel according to the revolution of motor, be multiplied by with the revolution of reel the position that corresponding radius just can calculate defect.Because cable winding radius in rotation process is change, if need accurate record position, the position of reel revolution accurate Calculation defect can be multiplied by with the radius of change.
Concrete detection method comprises the steps;
1) start the first motor and the second motor, tested cable is wound to volume Two winding apparatus from first volume winding apparatus; Meanwhile, the signal of monitoring control devices 8 pressure transducers;
2) in tested cable walking process, when controller goes out defect according to the input of 8 pressure transducers, record the detection data of this defect, record this defect position in the cable simultaneously;
3), after detecting, controller controls detection data and the defect positional information in the cable that display device shows the defect detected.
By such mode, when reeling complete, defect detecting device have detected whole cable, and (end connecting first volume winding apparatus cannot detect to this section of cable of defect detecting device, but this segment distance is very short, can ignore, also can be made up by other detection modes (such as manual observation)), just can the detection data of display defect and the position of defect, very convenient.
For the ease of the winding of cable on collecting device, can not come off from collecting device, the two ends of cable can be fixedly connected on the reel of first and second collecting device with glue or other fixed sturctures (such as clamping part clamping end or utilize pressure head to be pressed in drum wall end).
Although the present invention illustrates with regard to preferred implementation and describes, only it will be understood by those of skill in the art that otherwise exceed claim limited range of the present invention, variations and modifications can be carried out to the present invention.
