Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railway which is provided in a service line of a railway, temporarily stores containers carried by freight trains, sorts the containers by destination, and reloads the chassis (trailer). The present invention relates to a container terminal for use.

[0002]

2. Description of the Related Art Conventional container terminals for railways use a forklift to unload containers transported by freight trains, store them in container yards in two or three stages, and store them again by a forklift. -It was loaded on the ship and transported outside.

[0003]

However, in such a conventional container terminal, 1) a large space is required because the number of stacks cannot be increased, and 2) manual operation by a forklift. It takes a lot of labor 3)
If you want to ship the lower container first, you have to remove the upper container before shipping.
There is such a problem.

[0004] The present invention has been made in view of such problems of the prior art,
A container container for railroads, which was devised, uses three-dimensional storage equipment, requires less space, can reduce the number of personnel by automation, and can transport containers from any storage location. -To provide a terminal.

[0005]

In order to achieve the above object, a railway container terminal according to the present invention is a rail terminal for a freight train.
And a container storage facility for transferring containers between the freight train and the chassis and storing the containers. Container storage forming container storage cells arranged on both sides along the crane travel path and provided in multiple stages in the height direction and arranged so that the depth from the crane travel path matches the longitudinal direction of the container A shelf, a stack crane that runs on a crane running rail provided above the storage shelf, and a spreader that grips the container on the lower surface and runs independently with driving wheels, and the stack crane runs on a crane. A trolley that runs on rails, a guide post that is suspended from the trolley, and can be moved up and down along the guide post And a lifting frame having a spreader running rail on the lower side, and a spreader running rail provided on the lifting frame when transferring containers to and from the stack crane in the container storage cell. A connecting spreader running rail is provided.

Next, the operation of the present invention will be described. The container carried by the freight train enters the container storage facility while being loaded on the train. To transfer a container from a freight train to a container three-dimensional storage cell in the container three-dimensional storage facility, the following is performed. First, the position of the freight train in the traveling direction is adjusted so that the container can be lifted by the stack crane. After that, Stack Clay
The spreader is suspended on the lifting frame of the fin, the lifting frame is lowered, the spreader is placed on the container, and the container is gripped by the twist lock mechanism provided at the four corners of the spreader, and the lifting is performed. Raise the frame and lift the container. Thereafter, the stack crane is run to stop in front of the target container storage cell, the spreader running rail of the lifting frame is aligned with the spreader running rail of the container storage cell, and the spreader is run. The container is housed in a storage cell. After the spreader is separated from the container, it starts running and moves up and down again.
Suspended in the room.

[0007] Since the containers are stored three-dimensionally, the storage space can be reduced. Since the stack crane can be automated, the number of personnel can be reduced, and shipping can be performed from any container storage cell, so that cargo handling efficiency can be improved.
