GANTRY TYPE MOVEABLE CATENARY SYSTEM AT RAILWAY CROSSING

摘要

The present invention relates to a moveable catenary of a gantry type crossing and, more specifically, to a moveable catenary of a gantry type crossing capable of being easily applied to and constructed at a new crossing and an existing crossing with a simple and stable structure and enabling complete operation, repair and maintenance. The moveable catenary of the gantry type crossing comprises a pair of sub-rails (110) which are installed in parallel with a rail on the left and right sides of a crossing rail (10) and have a constant length; a frame structure which is connected to a driving motor (130) and is moved on the sub-rails and of which lower end is mounted on the sub-rail; a movement catenary (160) which is connected to the upper part of the frame structure with an insulator (152), is installed in parallel with a catenary (20), and has a constant length; and a control unit which controls the driving motor and operates the frame structure. A second power connection unit (161) of both ends of the moveable catenary (160) is connected or separated from a first power connection unit (21) of the catenary (20) according to the movement of the frame structure, thereby offering the moveable catenary of the gantry type crossing which supplies or blocks power.
