technical field

The invention relates to the technical field of cable damage detection, in particular to a cable damage detection device and a detection method thereof.

Background technique

The outside of the cable is usually wrapped with an insulating layer. Before the cable is put into use or the cable is recycled, it is necessary to detect the damage of the insulating layer to prevent the damaged cable from causing electrical safety accidents in actual use. The insulation of the cable Due to long-term bending or contact with metal sharp objects during transportation, cracks will appear on the outer side of the insulating layer. Currently, when cracks are detected, workers generally need to pull the cable from the top of the cable winding roller to the outside. Check whether the outer side of the cable insulation layer is damaged. When there is dust attached to the outer side of the cable insulation layer, the staff needs to wipe the dirty cable clean, and then check whether the outer side of the cable is damaged. The entire cable insulation Layer damage detection requires a lot of manpower, and the detection efficiency of cable damage is not good.

A cable breakage detection device according to claim 1, characterized in that two connection blocks are fixed on the bottom surface of the support plate (210), and the two connection blocks are rotatably connected with guide rails. (110) moving wheels connected by rolling, one end of the 匚-shaped frame (200) is fixed with a chassis one (240), and the inside of the chassis one (240) is fixed with a motor one fixedly connected with the two-way lead screw (220) , the top of the L-shaped plate 2 (310) is detachably fixed to the chassis 2 (311), the interior of the chassis 2 (311) is fixed with the motor 2, and the output end of the motor 2 is aligned with the corresponding positioning shaft ( 400) is detachably fixedly connected, the outer side of one of the support plates (210) is fixed with the chassis three (320), the inside of the chassis three (320) is fixed with the motor three, the output end of the motor three and the corresponding position L-shaped plate one (300) is fixedly connected. 9. A detection method of the cable damage detection device according to any one of claims 1-8, wherein the method specifically comprises the following steps: Step 1: Install fixed take-up rollers (410) on the two positioning shafts (400), wrap the cable to be tested on one take-up roller (410), and wind one end of the cable with the other The roller (410) is wound and fixed, and the fixed chassis two (311) is installed above a winding roller (410); Step 2: The motor 1 rotates with the two-way lead screw (220) to move the two support plates (210) closer to each other, and the two connecting rods 1 (810) move toward the direction of the cable with the connecting rod 2 (820), thereby making the The extruding column (611) moves to the middle of the cable, and the cable is extruded into an arc and arranged outside the extruding column (611); Step 3: Cracks on the outer side of the cable insulation layer are easy to appear after bending. At this time, the camera (910) records the cable and transmits the recorded image to an external computer to analyze whether it is damaged; Step 4: The motor 3 rotates with the corresponding L-shaped plate 1 (300), and the two L-shaped plates 2 (310) rotate synchronously through the sleeve 1 (520) and the sliding rod (530), so that the cable Rotating on the outside of the extrusion column (611), it is convenient to bend and arrange different outer positions of the insulating layer on the outside of the extrusion column (611), so as to realize all-round damage detection at the same position of the cable; Step 5: Motor 2 rotates with the winding roller (410) at the corresponding position to make the winding roller (410) rotate to wind up the cable, and the other positioning shaft (400) drives another winding roller (410) to rotate to release the cable , realize the transmission of the cable between the two winding rollers (410), and detect whether the cable is damaged at different lengths; Step 6: The motor four drives the driving gear (620) to rotate, so that the driven gear (711) drives the casing two (710) to rotate, makes the casing three (720) rotate with the extrusion column (611), and the extrusion column The position of the arc-shaped sponge block (6111) on (611) is turned to the position outside the cable; Step 7: The extrusion column (611) is screwed and moved on the shaft (610), and the motor four is controlled to make the extrusion column (611) reciprocate and move up and down on the shaft (610), and the arc-shaped sponge block (6111 ) position on the outside of the cable to wipe the cable, so that the camera (910) can clearly record the cable.
