And more particularly to a tiltable mobile telecommunication line system.

Generally, a container is used to transport the cargo. Containers are easy to pack, easy to transport, and can protect cargo inside. Containers are classified as land containers and marine containers.

The land vehicles are mainly transported using trailers and freight trains.

When a container is transported using freight trains, freight trains will transport the containers to two or more railway container logistics bases where the trains are located. Containers loaded at the container yard of the railway container logistics base are transported to the destination using land or water transportation means.

In this connection, the inventor of the present invention has found that, as shown in Korean Patent Registration No. 10-0977745, A plurality of train stands installed next to the main orbit; Fixed support units fixedly coupled in cantilever manner to the subway trains other than the subway trains corresponding to the cargo platform; Upper and lower drive supporting units coupled to each other in a cantilever manner so as to rotate in vertical directions, respectively; A fixed catenary coupled to the fixed support units such that the section in which the up and down driven support units are located is cut off and is positioned above the main orbit along the main orbit; A movable tram line connected to the up and down driven support units and circularly moving in the up and down direction in accordance with the upward and downward rotation of the up and down driven support units; And switching units for connecting the movable catenary line and the fixed line when the up and down driven support units are horizontally positioned. The present invention relates to an electric cargo train capable of moving wagons of an electric cargo train to the side of a cargo platform and shortening the time required to load containers on the wagons of the electric cargo train and to lower containers placed on the wagons, And proposed a portable tramway system for container transportation using trains.

More specifically, as shown in FIGS. 10 to 12 of Patent Document 1, the upper and lower drive type support units 300 are rotated by 90 degrees so as to be in a vertical state in a horizontal state. As the upper and lower driven support units 300 are rotated by 90 degrees, the mobile transmission line 500 (s) coupled to the upper and lower driven support units 300 are moved away from the fixed transmission line 400 by 90 degrees do. In other words, the upper and lower driven support units 300 lift the moving electric cable 500 toward the train wheels 100. Therefore, the rich stacker C located at the cargo landing platform A picks up the container placed in the car, moves to the container yard, and then loads the container in the container yard. Thus, the moving car line 500 The working radius of the rich stacker C is avoided, and the workability of the rich stacker C is improved.

However, if the distance between railway tracks is narrow in the container yard of the railroad history, there is a possibility that the container carried by the Rich Stacker (C) and the iron stock of the moving electric car line may collide with each other. Furthermore, (RMGC) is used for loading and unloading a container. When picking containers from a freight train's flat car, proceeding both at the same time and at the same time, there is a danger of collision between the container have.

1 and 2, the electric elevating and lowering movable electromotive catenary system for carrying containers according to the present invention comprises an outer pole 10, an inner pole 20, a cantilever 21 fixed to the moving catenary 23, , And a stretching member (30).

The external electric pole 10 may be a tubular column having a predetermined length, and is vertically buried in the ground from the ground, and an internal space is formed therein. The concrete block 11 is embedded in the ground from the ground to fix the outer pole 10 to the ground and the upper part of the outer pole 10 can be fixed to the concrete block 11 by the anchors 12 have.

The inner electric pole 20 can be a tubular or rod-like column having a predetermined length and is inserted into the inner space of the outer pole 10 and can be moved upward and downward along the outer pole 10 .

The cantilever beam 21 is a rod or a frame having a predetermined length and is disposed horizontally at an upper portion of the inner pole 20. The movable transducer 23 is connected to the free end of the cantilever beam 21 opposite to the portion fixed to the inner pole and the other end of the cantilever beam 21 fixed to the inner pole 20 is driven by the driving unit 22 And is fixed to the inner electric pole 20.

The driving unit 22 may be used for varying the position of the cantilever 21 to change the position of the moving cranes 23 and may include gears or other mechanisms connected to the motor and the motor. The cantilever beam 21 connected to the moving catenary line 23 at the free end thereof during the operation of the driving unit 22, as in the structure applied to the patent document 2 proposed by the present inventor (Korean Patent No. 10-0940767) Since the structure for rotating the driving unit 22 with the rotation axis of the driving unit as a starting point can be applied during the operation of the driving unit 22 as in the structure applied to the stretching and driving mechanism or the structure disclosed in Patent Document 3 (Korean Patent No. 10-1413670) The detailed description of the driving or tilting drive will be omitted.

Here, the driving of the cantilever 21 of the present invention to be described later is exemplified in which a cantilever rotation driving structure is applied as in Patent Document 3. Since the moving cantilever 23 moves in the horizontal direction in any driving structure, The height of the base 23 does not change.

The elevating means is for moving the internal electric pole 20 up and down in the vertical direction. More specifically, the elevating means includes a stretching member 30 installed parallel to the inner pole 20 at a predetermined distance from the inner pole 20 and having a variable length in the vertical direction, A first fixing part 31 fixed on the concrete block 11 in which the electric pole 10 is embedded and a second fixing part 30 fixed to the upper part of the inner electric pole 20 at an upper end of the elastic member 30 32).

The telescopic cylinder having a large variable width and a stable length can be applied to the stretchable member 30 in consideration of the fact that the length of the inner pole 20 is about 4 to 5 m. There is no limitation on the type and structure of the elastic member 30.

As a preferred embodiment, the second fixing part 32 is hinged to the free end of the extending rod 33 extending in the horizontal direction at the upper part of the inner electric pole 20, and the first fixing part 31 is hinged Can be hinged on the concrete block (11). Here, 'hinge joint' refers to a state in which mutual rotation can be performed between respective connected structures by being connected through a hinge. Since the upper and lower ends of the elastic member 30 are rotatably connected to each other through the hinge, when the inner pole 20 of the inner pole 20 is moved or tilted slightly in the horizontal direction, The inner pole piece 20 and the elastic member 30 can be moved up and down in parallel with each other at the same time, so that stable driving and standing can be maintained. have.

1 and 2, the movable electric wire 23 can be coupled with a fixed electric wire (not shown) while the inner electric pole 20 is lifted up to the uppermost position. In this state, Since the electric power is supplied to the catenary line 23, the freight train 41 can enter the container yard of the railroad history on the railroad rail 40.

FIG. 3 is a schematic view of a railroad historical container yard to which a movable up and down movable type electric cable line system for carrying containers according to a first embodiment of the present invention is applied, in which a moving electric cable line is separated from a fixed electric cable line for descending of a pole, Fig. 4 (a) is an enlarged view of the main part of Fig. 3, and Fig. 4 (b) is a side view of Fig.
