Cable laying meter counting flaw detection device

The utility model discloses a meter-counting flaw detection device for cable laying. The meter-counting flaw detection device comprises a base and a first support frame, the cable pay-off device has the advantages that the motor drives the conveying roller to rotate, cable pay-off work of a cable is achieved, flaw detection is conducted on the cable through the flaw detection mechanism during cable pay-off, when the conveying roller rotates, the encoder records the number of rotation turns, and then cable pay-off length counting work is achieved. The problems that existing equipment in the market is single in function and low in automation degree and needs large factors of human intervention are solved, manpower resource investment is reduced as much as possible, high integration of the cable laying device is achieved, and cable traction, meter counting and outer layer flaw detection are integrated into a whole. The functions of cable laying, meter counting, flaw detection on the outer layer of the cable, aut
