Abstract

The invention relates to the technical field of railway maintenance, in particular to a method of polishing steel rails in a switch area. The method includes: acquiring in situ outline data of a first stock rail and outline data of an integrated rail formed by abutting a point rail to a second stock rail; through the outline data acquired in situ, according to a wheel-rail contact geometrical algorithm, calculating the positions of wheel-rail contact points of the first stock rail and the integrated rail; according to the position of the wheel-rail contact point of the integrated rail, based on a rail central line between the first stock rail and the integrated rail, polishing the outline of the first stock rail so that the wheel-rail contact point of the first stock rail and that of the integrated rail, in symmetry about the rail central line. The method has the advantages that the amplitude of S-swing of a locomotive is effectively reduced, the wheel-rail power action is relieved, the quality of a train passing the switch is improved, wear of the point rail is reduced, and the service life of a railway is prolonged.

Description

technical field [0001] The invention relates to the technical field of railway maintenance, in particular to a rail grinding method in a turnout area of ​​a turnout. Background technique [0002] In the process of track laying, in order to implement the overall line, there are often two or more tracks cross-connected together. In order to enable the locomotive to transition between the two tracks, a switch switch is designed in the track switch area. [0003] The switch switch in the related art includes the first basic rail, the second basic rail, the first switch rail and the second switch rail; the first track includes the first inner rail and the first outer rail, and the second track includes the second The inner rail and the second outer rail; one end of the first inner rail and the second inner rail are connected, and there is an acute angle between the first inner rail and the second inner rail; one end of the first basic rail is connected to one end of the first ou...
