GANTRY TYPE MOVABLE CATENARY SYSTEM AT A RAILWAY CROSSING

摘要

The present invention provides a gantry type movable catenary system at railway crossing having a simple and reliable structure, which can be applied to a conventional railway crossing as well as to a new railway crossing, and at the same time is improved such that service and maintenance are easy. The gantry type movable catenary system according to the present invention comprises: a pair of auxiliary rails 110 with a fixed length installed in parallel with railway rails 10 from the right and left outsides of the railway rails at the crossing; a frame structure of which a lower end is installed on the auxiliary rail, the frame structure being connected with a drive motor 130 to be reciprocally movable on the auxiliary rail; a movable contact wire 160 with a certain length connected via an insulator 152 On top of the frame structure and installed to parallel to a catenary wire 20; and a control unit which controls driving of the drive motor to operate the positioning of the frame structure, wherein, from a first power connecting section 21 of the catenary wire 20, a second power connecting section 161 of the both ends of the movable contact wire 160 is connected or disconnected depending on reciprocal movement of the frame structure, thus supplying or disconnecting electric power.
