The invention discloses a wire saw constant tension rope take-up track used for cutting concrete and stone. The track is structurally formed by assembling a bi-directional piston with an oil seal, a piston rod, a round oil cylinder barrel, a round bottom end oil cylinder cover with an oil duct hole, a square top end oil cylinder cover with an oil duct hole, a square track inner sleeve, a square track sliding outer sleeve, a corresponding sealing part, a connecting part and an oil inlet and outlet hole opening through a welding technology. Under the effect of hydraulic oil pressure, the square track sliding outer sleeve moves on the square track inner sleeve telescopically in a reciprocating mode, and therefore the wire saw track has a rope take-up function. The wire saw track can serve as a track support and has a reciprocating telescoping rope take-up function. The track has constant tension, does not need to be adjusted and operated from time to time, and has excellent performance of resisting mud pollution, and the structure foundation is laid for automatic operation of a wire saw.
