A ground track change facility for a track gauge bogie

Abstract

The invention relates to the field of railway vehicle variable gauges and discloses a ground rail transfer device used for a variable-gauge bogie. The ground rail transfer device comprises a pair of supporting rails arranged in parallel, a pair of first guide rails, a pair of variable-gauge guide rails and a pair of second guide rails, wherein the first guide rails, the variable-gauge guide railsand the second guide rails are sequentially arranged along the inner sides of the pair of the supporting rails. Unlocking sections are arranged between the first guide rails and the variable-gauge guide rails, locking sections are arranged between the variable-gauge guide rails and the second guide rails, pushing locating devices are arranged on the inner / outer sides of the unlocking sections andthe inner / outer sides of the locking sections and used for applying transverse thrust to variable-gauge wheel sets of the variable-gauge bogie passing through the unlocking sections and the locking sections, unlocking emergency braking sections are arranged behind the unlocking sections, and locking emergency braking sections are arranged behind the locking sections. Unlocking and locking reliability is improved, emergency braking can be conducted conveniently once a train fails in unlocking or locking, and potential safety hazards existing on existing ground rail transfer devices are eliminated.

Description

technical field [0001] The invention relates to the technical field of gauge change of rail vehicles, in particular to a ground track change facility for a gauge change bogie. Background technique [0002] Spain and Japan have successively invented wheel sets with variable gauges, which can run continuously between tracks of different gauges. [0003] At present, the lateral positioning of the wheel is directly realized by the guide rail, but due to the existence of guide rail gaps, the positioning is prone to inaccurate situations, resulting in a large lateral pressure exerted by the axle box and the outer sleeve on the locking pin, resulting in When it moves, it is subjected to a large vertical friction force, which makes the unlocking and locking actions of the locking pin prone to jamming, and cannot be successfully unlocked or locked; After entering the track changing section directly, there is no corresponding detection method for whether the unlocking is successful, ...

Problems solved by technology

[0003] At present, the lateral positioning of the wheel is directly realized by the guide rail, but due to the existence of guide rail gaps, the positioning is prone to inaccurate situations, resulting in a large lateral pressure exerted by the axle box and the outer sleeve on the locking pin, resulting in When it moves, it is subjected to a large vertical friction force, which makes the unlocking and locking actions of the locking pin prone to jamming, and cannot be successfully unlocked or locked; After entering the track changing section directly, there is no corresponding detection method for whether the unlocking is successful, and there is no emergency treatment after the unlocking fails. Once the unlocking fails and the train directly enters the track changing section, it will cause damage to the gauge wheel set. , resulting in heavy losses; correspondingly, there is no corresponding detection method for whether the train is locked normally after entering the locking section, and there is no emergency treatment measure after the locking failure, which makes the current ground track change facilities have a relatively large safety hazard
