Description

INTERMODAL FREIGHT TRANSPORT SYSTEM AND INTERMODAL FREIGHT TRANSPORTING METHOD}

The present invention provides an intermodal freight transport system and an intermodal freight transport method capable of transporting container freight.

With the expansion of free trade, the volume of containers processed in ports is increasing as the global trade market is formed. Road transport-oriented freight transport systems cause traffic congestion, increase air pollution and noise, and increase maintenance costs due to large traffic accidents and road damage. In addition, after the container is transported to the port by road, the container loaded in each vehicle must be moved by ship or rail by crane, which takes a lot of time and money.

Rail transport systems are land transport systems that can transport large quantities of passengers and cargo in vehicles traveling on rails. In order to unload a large amount of cargo such as a container by using such a rail transport system, after replacing the electric locomotive with a diesel locomotive, it was difficult to move to a track without a tram line and unload using a crane.

In order to solve this problem, an inter-modal freight transport system capable of continuously transporting logistics is under research and development. In particular, a TOFC (trailers on flat cars) transport system that transports trailers in trucks is introduced. Is being studied. However, the conventional TOFC transport system has a problem that it takes a lot of time to move the trailer coupled to the freight vehicle.

On the other hand, the other side of the second elastic member 123 may be connected to the wagon top plate 161. The second elastic member 123 may be formed of an elastic band or a tension spring.

The first elastic member 121 and the second elastic member 123 are connected to the corner portion located on the same side in the width direction of the truck upper plate 161. That is, when dividing the wagon top plate 161 into two regions by the center line of the imaginary line passing through the center in the width direction of the wagon top plate 161, the first elastic member 121 and the second elastic part are located at the corners located in the same area. The member 123 is connected and installed.

Accordingly, the first bogie 165 is pressed by the first elastic member 121 to rotate in one direction (counterclockwise in FIG. 7), and the second bogie 166 is driven by the second elastic member 123. It is pressed to rotate in the direction opposite to one direction (clockwise in FIG. 7).

When the railroad vehicle 160 enters the turning section D2 in the driving section D1, the first bogie 165 is rotated counterclockwise with respect to the truck top plate 361 by the first elastic member 121. The second cart 166 may rotate in a clockwise direction with respect to the truck upper plate 161 by the second elastic member 123 and move to different rails.

On the other hand, as the first truck 165 and the second truck 166 are spaced apart in the width direction, when the truck upper plate 161 rotates, the first truck 165 rotates clockwise with respect to the truck upper plate 161, The second bogie 166 rotates at a larger angle in the clockwise direction with respect to the truck top plate 161. When the first bogie 165 rotates in the clockwise direction, the first elastic member 121 expands, but moves along one rail, so that the first bogie 165 can stably rotate during the movement. It is sufficient that the first elastic member 121 and the second elastic member 123 have elastic force only enough to allow the trolley to rotate at the branch point.
