Description
Technical Field
The invention relates to the technical field of track construction, in particular to a track panel supporting device with a transverse synchronous movement and ultra-high stepless adjusting mechanism.
Background
The double-block ballastless track has the advantages of strong adaptability, good economy, convenient construction and the like, and is one of the main structural forms of the ballastless track in China. The traditional double-block ballastless track panel supporting frame method is constructed by adopting a combined mode of a tool rail, a screw adjuster and a template. When the track panel is lifted, the track gauge is generally reduced (generally reduced by 1 mm-2.5 mm) according to the field test, and the track panel is impacted to a certain extent during concrete pouring operation, and the track gauge is influenced by manually standing on the track panel for refining and vibrating. When the existing screw rod regulator regulates the track direction, synchronous operation is required to be carried out on two sides of the track panel, but on a construction site, the probability of the synchronous operation of workers is very small, and adjustment deviation can be generated on two sides, so that the track direction and the track gauge can be influenced, internal force can be generated on sleeper truss steel bars, and the track bed is caused to crack. In a curve section, due to the existence of the super height, the supporting screw rod must be rotated by a proper angle to be perpendicular to a base surface, and at present, the screw rod regulator used for double-block ballastless track construction cannot realize super-height stepless adjustment, so that the setting requirements of different super-height and super-height transition sections are not met. Based on the above, it is necessary to design a track panel supporting device which has a reasonable structure and can be accurately adjusted.
