Description

Vertical and horizontal movement type mobile lane system {MOVABLE CATENARY SYSTEM WITH UP-DOWN ROTATION AND PARALLEL MOVING TYPE}

The present invention relates to an up-and-down rotation and parallel movement type mobile tram line system for railway freight handling vessels, and more specifically, to a plurality of tracks from a railway freight handling ship installed in a container yard or port container yard of railway station to one mobile tram facility. The present invention relates to an up-and-down rotation and parallel-moving mobile tram line system for a cargo handling ship that enables selective access to a plurality of fixed tram lines.

Containers are generally used to transport cargo. Containers are easy to pack, easy to transport, and can protect the cargo inside. Containers are classified into land containers and sea containers.

The land container is mainly transported using a trailer and a freight train.

When a container is transported using a freight train, the freight trains transport containers to and from the railroad container logistics base where two or more railroad tracks are located. Containers loaded in the container yard of the railroad container logistics base are transported to destinations by land or water transportation.

In this regard, the present inventor has a main track placed next to a cargo platform as seen in Korean Patent Registration No. 10-0977745 (Patent Document 1); A plurality of train poles installed next to the main track; Fixed support units that are fixedly coupled in the form of a cantilever beam to train poles other than the train poles corresponding to the cargo platform; Up and down driving type support units coupled to the train poles corresponding to the cargo platform in a cantilever shape to rotate in the vertical direction, respectively; The fixed tram line coupled to the fixed support units so that the section in which the vertical drive type support units are located is cut off and positioned above the main track along the main track; A movable tram line connected to the vertical driving type supporting units and circularly moving in the vertical direction according to the vertical rotation of the vertical driving type supporting units; And switching units connecting the moving and the fixed tram lines when the vertically driven support units are positioned horizontally. The present invention is to move the wagons of the electric freight train to the side of the cargo platform, to shorten the time to load the containers on the wagons of the electric freight trains or to unload the containers placed on the wagons, and to further simplify the electric freight arrangement. A mobile lane system for transporting containers using trains has been proposed.

In addition, the present inventor has a predetermined length, as seen in the Republic of Korea Patent Registration No. 10-1607462 (Patent Document 2), is buried vertically from the ground to the ground, the inner pole is formed in the interior space; An inner pole having a predetermined length, inserted into the indentation space of the outer pole, and coupled up and down in the vertical direction along the outer pole; It has a certain length, and is disposed in a horizontal direction from the top of the inner pole, the free end is connected to the moving tram line, the other end is connected to the upper portion of the inner pole by means of a driving unit including a motor, thereby operating the driving unit. A cantilever beam that is installed to be capable of being driven to drive in the longitudinal direction with the height of the moving tram line unchanged, or to rotate and drive about the rotation axis of the driving unit; Elevating means for driving the inner pole up and down in the vertical direction; It also proposed a vertically movable mobile lane system including Jeonju.

However, in the case of Patent Document 1, since the vertical drive-type support unit is configured to be capable of only vertically rotating driving, there is a disadvantage in that it cannot be applied in a system in which the connection bracket of a moving train line is horizontally parallel to and connected to the connection bracket of a fixed train line. In addition, both Patent Document 1 and Patent Document 2 require a lot of space to construct a number of mobile train lane facilities, since multiple track tracks must be installed in each track when multiple track tracks are installed around the train pole (jeonju). There is a problem in that there is no system installation cost, and a large number of mobile lane facilities need to be individually maintained, which requires a high management cost.
