The invention relates to a cable laying length measurement device, in particular to a cable laying length synchronous measurement device and aims at solving the problem of lacking the cable laying length synchronous measurement device. The cable laying length synchronous measurement device comprises a distance measurement wheel, a distance measurement wheel bracket, a distance measurement instrument fixed on the distance measurement wheel, two auxiliary wheels and an inter-wheel bracket; the distance measurement wheel is provided with a center shaft with the two ends lengthened and is supported on the distance measurement wheel bracket through the center shaft; the inter-wheel bracket is composed of four supporting rods with the length larger than a radius of the distance measurement wheel; two supporting rods form a group; the positions of the two supporting rods in each group are opposite to each other and arranged in the radial direction of the distance measurement wheel; one ends of the two supporting rods in each group are welded with and fixed to the center shaft on the two sides of the distance measurement wheel respectively; long holes opposite to each other in the radial direction of the distance measurement wheel are formed in the other ends of the two supporting rods in each group respectively; the two ends of wheel shafts of the auxiliary wheels extend into the long holes respectively; and fastening nuts are screwed at the wheel shaft ends of the auxiliary wheels. The cable laying length synchronous measurement device has the characteristics of simple structure, convenience in use and accuracy in measurement and is an ideal cable laying measurement tool.
