Description

Technical Field

[0001] The utility model relates to the technical field of displacement limitation, in particular to a railway spare rail displacement limitation device. Background Art

[0002] The railway maintenance department's operating procedure for replacing rails as planned is generally to unload spare rails on the ballast on both sides of the rails that need to be replaced in advance (about a month or so), waiting for the construction window (usually during concentrated railway maintenance) for replacement.

[0003] After observation, it was found that when a train passes, the forward vibration generated is transmitted to the spare rail through the ballast, and the spare rail will move in the opposite direction of the train or down the slope as the train runs. The spare rail placed between the two lines of the double track with no slope will produce bidirectional displacement. Due to the influence of comprehensive factors such as empty and loaded vehicles, train running speed, ramps, curves, etc., the spare rail will still produce unidirectional displacement. When the displacement reaches a certain distance, it is necessary to use manpower and other methods to reset it, which affects the progress of the operation during track replacement and increases the safety risk when moving the spare rail; and the end of the spare rail often warps, there is a safety risk of train scratching the spare rail, endangering driving safety.

[0004] In order to prevent the spare rails from tilting and shifting, the railway engineering department installs a lateral displacement limiting device on the spare rails after removing them. However, the longitudinal displacement of the spare rails is difficult to limit, so the railway engineering department will arrange personnel to take additional trains or walk to inspect the displacement of the spare rails from time to time, and the workload of the inspection is also large.

[0030] In addition, the support rods 11 at both ends of the spare rail are inclined with the vertical plates 102 biased toward one side of the spare rail, thereby strengthening the support for the blocking part 12 on both sides and increasing the resistance to the longitudinal displacement in two directions that may occur due to the vibration of the spare rail ballast.
