Problems solved by technology

[0002] There are usually two traditional railway track changing methods, one is manual track changing, its disadvantages are time-consuming and labor-intensive, low efficiency and unsafe, and the other is mechanical track changing, its disadvantages are dismantling old rails and replacing them The new rail is operated by the same rail-changing car, so the rail-changing car itself is heavy and expensive, and the rail-changing car is easy to fall off when walking on the old rail with fasteners removed, causing accidents and failing to work

example 1

[0018] A. Transport the welded rails (new rails) with a length of 500m to the work area by a special long-rail transport vehicle, unload them and place them on the outside of the sleepers;

[0019] B. Remove all the fasteners manually or mechanically and scatter the removed fasteners to the center of the road;

[0020] C. Put the HG60 rail-changing car group on the flat car (the flat car is also equipped with fastener recovery vehicles, fastener machines, rail collision trolleys, and track alignment devices, etc.) Transport it to the work area in front, hoist the train set onto the new track with a gantry crane, the old track changer is in front, and the new track changer is behind, all walking on the new track;

[0021] D. The clamp on the old rail changing car clamps the old rail and moves it to the center of the line, then the old rail changing car moves forward 30m, and the new rail changing car moves forward correspondingly to the original position of the old rail cha...

example 2

[0023] In step D, the old rail replacement car clamps the old rail and moves it to the center of the line, and then moves forward for 20m, and the rest is the same as in Example 1.

example 3

[0025] In step D, the old rail changing car clamps the old rail and moves it to the center of the line, and then moves forward for 15m, and the rest is the same as Example 1.

Abstract

The invention discloses a steel rail quick replacement method which is characterized by including the following steps that (A) welded new rails are conveyed to a work area through a train and unloaded on the outer sides of sleepers; (B) buckles of old rails in the work area are all detached and scattered on rail cores; (C) a rail replacement trolley set composed of an old rail replacement trolley and a new rail replacement trolley is conveyed to the work area, the old rail replacement trolley is in front of the new rail replacement trolley, and the old rail replacement trolley and the new rail replacement trolley walk on the new rails; (D) a clamp on the old rail replacement trolley clamps the old rails and moves the old rails to a line center, and a clamp on the new rail replacement trolley clamps the new rails and moves the new rails into sleeper rail supporting grooves. The method is mainly used for rail replacement of railways.

Description

technical field [0001] The invention relates to a method for changing rails, in particular to a method for quickly changing rails. Background technique [0002] There are usually two traditional railway track changing methods, one is manual track changing, its disadvantages are time-consuming and labor-intensive, low efficiency and unsafe, and the other is mechanical track changing, its disadvantages are dismantling old rails and replacing them The new rail is operated by the same rail-changing car, so the rail-changing car itself is heavy and expensive. When the rail-changing car walks on the old rail with the fasteners removed, it is easy to fall off the track, causing an accident and failing to work. Contents of the invention [0003] The object of the present invention is to provide a method for quickly changing rails to overcome the above-mentioned shortcomings. [0004] In order to achieve the above object, the technical solution of the present invention is: a m...
