A switch of the motor 6 is turned on, and the floor 1 is rotated around the rotary shaft 2 via the small gear 5 and the large gear 4, so that an automobile is conveyed in/out from a dedicated home.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to loading and unloading vehicles such as trucks on freight wagons.

[0002]

2. Description of the Related Art Conventionally, automobiles have been transported by themselves or by ship, but transportation by rail has been difficult.

[0003]

[Problems to be solved by the invention]

I. Despite the railway, you can't carry cars as they are. B. The roads are saturated and the damage caused by traffic congestion and exhaust gas is becoming more serious. C. For shipments and perishables that require accurate time,
There was a risk that the driver would overdo the accident and cause anxiety about health. D. In the case of long distances, there are disadvantages such as driver burden, car consumption, and gasoline consumption. E. Loading and unloading containers is difficult.

[0004]

[Means for Solving the Problems] A platform dedicated to wagons is provided as an auxiliary means, and both ends of the platform are sloped so that cars can move around the platform. B. The floor (1) of the freight car and the main body are connected by a rotating shaft (2), and wheels (3) are provided so as to be rotatable. C. Under the floor (1), a large circular gear (4) centered on the rotating shaft (2) and a small gear (5) for transmitting power meshing with the large gear (4) are provided. D. The small gear (5) is fixed to the rotating shaft of the electric motor (6). E. FIG. By changing the rotation direction of the motor (6) by switching the switch, the floor (1) can be freely rotated. The present invention relates to a freight car loading / unloading apparatus configured as described above.

[0005]

[Function] The floor (1) of a freight car is rotated by an electric motor and gears and a part of the car gets on the platform, and the car rides on it as if it were in a garage. Then, the floor (1) rotates in the reverse direction and returns to the original state, and the vehicle is in a state parallel to the track. When you reach your destination, turn on the switch and rotate the floor to your convenience, and the car will be ready to start.
