Description

  The present invention relates to a movable platform fence device for isolating a space between a track on which a railway train travels and a platform.

  In order to isolate the space between the track on which the railway train runs and the platform, the conventional home fence device installed along the side edge on the platform is a door that opens and closes as passengers get on and off the railway vehicle. And a door pocket in which the door is stored when the door is opened. When the railway vehicle stops on the platform, the door of the railing device faces the entrance / exit of the railway vehicle. Door pockets are installed on both sides of the entrance. However, when deformed vehicles having different railroad vehicle entrance / exit positions stop on the same platform, for example, a train having four railroad entrances and a train having six gates on the same platform has the same platform. When stopping, even if you stop at the same position on the platform, the position of the entrance / exit is different, so if you install a platform fence according to the position of the entrance / exit of one train, you can get on / off the other train However, there was a problem that the door fence of the platform fence fixed to the platform would get in the way.

  Therefore, in order to solve such a problem, the conventional platform fence device corresponding to the deformed vehicle having different vehicle entrance / exit positions is divided into a plurality of groups, and each group is orthogonal to the longitudinal direction of the platform. Doors arranged in a plurality of rows shifted in the direction, door opening / closing means for moving the doors in the longitudinal direction of the platform, train-by-car detection means for detecting the train and stop position of the train stopped on the platform, and And a stop position detecting means, which forms an open section of a door corresponding to the entrance / exit of the train to be stopped based on the detection result of the stop position of the train and the train stopping on the platform (for example, , See Patent Document 1).
