The invention relates to the technical field of double-block ballastless track laying for high-speed railways, in particular to an internally supported screw adjuster and a rail row positioning method, including: a beam, a tray adjustment device, a vertical adjustment rod and a support rod; Both ends of the beam are equipped with a pallet adjustment device, which is used to adjust the gauge; both ends of the beam are provided with vertical adjustment threaded holes, and the vertical adjustment threaded hole is located between the two pallet adjustment devices; the vertical adjustment The outer peripheral surface of the rod is provided with an external thread matched with the vertical adjustment threaded hole to adjust the height of the track; the upper end of the support rod is connected with the lower end of the vertical adjustment rod for supporting the beam. Since the internally supported screw adjuster is located inside the rail row, it will not be unable to support the rail row at the preset position due to insufficient space outside the rail row. Therefore, the track geometry will not be deformed and the position will not be deviated. shift.
Description
technical field [0001] The invention relates to the technical field of double-block ballastless track laying for high-speed railways, in particular to an internally supported screw adjuster and a rail row positioning method. Background technique [0002] Ballastless track, also known as ballastless track, refers to the track structure that uses concrete, asphalt mixture and other integral foundations to replace the loose-grained gravel track bed. The roadbed of ordinary railways is laid with gravel, and the sleepers are prefabricated concrete sleepers or wooden sleepers. The sleepers of the ballastless track are directly poured with concrete, and the steel rails and sleepers are directly laid on the concrete roadbed. The most important feature of ballastless track is precision, and its error is calculated in millimeters, which is an objective requirement for the safety, ride comfort and stability of high-speed trains. In order to ensure the accuracy of the ballastless trac...
