Movable precise adjusting device for track slab

The invention discloses a movable precise adjusting device for a track slab, relates to a railway track, in particular to a precise adjusting device for the track slab during the construction of high-speed railway ballastless tracks. The adjusting device comprises a running mechanism, support legs and adjusting mechanisms, wherein the running mechanism consists of a frame, a driving wheel mechanism, a bearing wheel mechanism and a guide wheel mechanism; the driving wheel mechanism and the bearing wheel mechanism are arranged below the frame at intervals; the guide wheel mechanism is arranged below the frame; and no less than one pair of adjusting mechanisms and no less than one pair of support legs are arranged below the frame. In the movable precise adjusting device for the track slab, automatic servo control can be used completely due to the adjusting mechanisms; the support points and end support points of the track slab in an adjusting process are at the same position; and the end support points and the adjusting mechanisms can be separated, so that labor force and equipment are saved and operating efficiency is improved.
