The utility model discloses a lifting slideway of a full-hydraulic automatic catwalk. The lifting slideway comprises a front segment, a rear segment, a pushing slide plate, a pushing pulley, a connecting pin and a chain. The lifting slideway is used for conveying a drill rig to a drill platform or reclaiming the drill rig. The pushing pulley drives the pushing slide plate to move along the slideway through the chain; the drill rig is pushed to a wellhead or reclaimed to the slideway; the drill rig can be fixed to the pushing slide plate to prevent the pushing slide plate from sliding along the slideway. The slideway is in a segmental structure, including the front segment and the rear segment; the length of the front segment is about half that of the rear segment. The center of gravity of the whole lifting slideway is on the back, and the basis is provided for stability control; both the front segment and the rear segment are provided with V-grooves and fall-proof mechanisms, and conveying stability of the drill rig is well guaranteed; the front segment and the rear segment are connected together through a slideway connecting block and a connecting hinging block, and mounting, demounting and conveying are facilitated; the lifting slideway is integrally controlled mechanically, electrically and hydraulically, automation level is high, and the spatial attitude is good.
