MOVABLE CATENARY OF GANTRY TYPE 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 new crossings and existing crossings with a simple and stable structure and enabling complete operation, repair and maintenance. To this end, 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 which 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 the 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 of the driving motor and operates the frame structure. A second power connection unit (161) of both ends of the moveable catenary (160) is connected to or separated from a first power connection unit (21) of the catenary (20) according to the reciprocating movement of the frame structure, thereby offering a moveable catenary of a gantry type crossing which supplies or blocks power.
