MOVEABLE CATENARY SYSTEM FOR CARRYING CONTAINERS USING AN ELECTRIC CONTAINER FREIGHT TRAIN
First Claim
1. A moveable catenary system for carrying containers using an electric container freight train comprising:
- a main rail track;
a plurality of catenary masts installed beside the main rail track along the main rail track;
a fixed catenary located above the main rail track along the main rail track, the fixed catenary having a partially broken section;
fixed support units respectively joined and fixed to some of the plural catenary masts in a cantilever form for supporting the fixed catenary;
a moveable catenary located at the broken section of the fixed catenary;
vertical driving support units respectively joined to some of the plural catenary masts in the cantilever form for lifting up the moveable catenary toward the catenary masts or lowering the moveable catenary toward the fixed catenary while moving vertically to keep horizontality or perpendicularity relative to one side; and
switching units for connecting the moveable catenary with the fixed catenary or disconnecting the moveable catenary from the fixed catenary while the moveable catenary moves vertically,wherein each of the switching units comprises;
a plurality of guide bolts joined to a cut end portion of the fixed catenary;
springs respectively inserted into the guide bolts;
a plate type terminal supported by the springs and joined with the guide bolts in such a way as to vertically move as long as a set distance; and
a curved terminal joined to an end portion of the moveable catenary and being in contact with the plate type terminal or being separated from the plate type terminal according to the vertical movement of the moveable catenary.

Abstract
A moveable catenary system for carrying a container using an electric container freight train includes: a main rail track disposed beside a freight platform; a plurality of catenary masts disposed beside the main rail track; fixed support units fixedly coupled in a cantilever shape to the catenary masts, respectively, with the exception of the catenary masts corresponding to the freight platform; vertical driving support units coupled in the cantilever shape to the catenary masts corresponding to the freight platform so as to vertically rotate the catenary masts, respectively; a fixed catenary coupled to the fixed support units such that positions at which the vertical driving support units are disposed are cut and the vertical driving support units are disposed inside and along the main rail track; a moveable catenary connected to the vertical driving support unit, the movable catenary being circularly moved in a vertical direction according to the vertical rotation of the vertical driving support units; and switching units connecting the moveable catenary to the fixed catenary when the vertical driving support units are disposed in a horizontal direction. According to the present invention, freight cars of the electric container freight train may be moved beside the freight platform to reduce the time required for loading containers into the freight cars of the electric container freight train or unloading containers mounted on the freight cars. Furthermore, the rail track may be simply arranged.
