Abstract

PROBLEM TO BE SOLVED: To attain space reduction and automation, and carry out a container even from any storage position by arranging a container multistory storage facility composed of a container storage shelf having container storage cells in a multistage shape in the height direction, a stack crane and a spreader to self-travel by gripping a container on an under surface. SOLUTION: A container 10 carried by a freight train 6 is loaded on a bogie 4 by a gate-shaped crane 12, and enters a container multistory storage facility 20. A stack crane 3 is moved just above the bogie 4, and a raising-lowering frame is lowered, and the container 10 is gripped by a spreader. The raising- lowering frame is raised, and the stack crane 3 is made to travel, and is stopped before an object container storage cell 2h. The spreader is made to travel, and the container 10 is placed on a bracket in the container storage cell 2h. The spreader is made to travel, and is again returned in the raising-lowering frame.

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 is required. 3) If the lower container needs to be shipped first, the container must be shipped after the upper container is removed, which causes a problem such as poor cargo handling efficiency.

[0004] The present invention has been made in view of such problems of the prior art,
It was devised. By adopting a three-dimensional storage facility, the space can be reduced, the number of personnel can be reduced by automation, and the container container for railway can be carried out from any storage location. The purpose is to provide minals.

[0005]

In order to achieve the above object, a railway container terminal according to the first invention of the present application circulates and runs between a container storage facility and a freight train and a container storage facility. And a gate-type crane that travels alongside the rail over the train and the rail for the carriage, and transfers containers between the train and the carriage. The three-dimensional storage facility is arranged along the crane travel path on both sides of the crane travel path, and
Container storage shelves, which are provided in multiple stages in the height direction and form container storage cells arranged so that the depth from the crane traveling path matches the longitudinal direction of the container, and a crane traveling rail provided above the storage shelves It consists of a stack crane running on the top, a spreader that grips the container on the lower surface and runs independently with drive wheels, and the stack crane runs on the crane running rail and hangs down from the trolley. A guide post to be provided,
An elevating frame that is provided to be able to move up and down along the guide post, and has a spreader traveling rail on the lower side, and the container storage cell is configured to move up and down when transferring a container to and from the stack crane. A spreader travel rail connected to the spreader travel rail provided on the frame is provided.

A railway container terminal according to the second invention of the present application is a container storage facility, a truck for circulating between a freight train and the container storage facility and transporting containers, a train and a truck. One of the legs rests on a rail provided on the side wall of the three-dimensional container storage facility, and the container passes between the train and the bogie. The three-dimensional storage facility for containers is arranged along the crane travel path on both sides of the crane travel path and is provided in multiple stages in the height direction, and the depth from the crane travel path is Container storage shelves forming container storage cells arranged so as to coincide with the longitudinal direction of the container, a stack crane traveling on a crane traveling rail provided above the storage shelves, and holding the container on the lower surface The stack crane is provided with a trolley running on a crane running rail, a guide post provided hanging from the trolley, and a vertically movable guide along the guide post. A lifting frame having a spreader running rail on the lower side, and the container storage cell is connected to a spreader running rail provided on the lifting frame when a container is transferred to and from the stack crane. A spreader running rail is provided.

Next, the operation of the present invention will be described. Containers transported by freight trains are loaded onto carts by gate crane or semi-gate crane. The trolley moves on the trolley rail and enters the container storage facility. The transfer of a container from a trolley to a container three-dimensional storage cell in the container three-dimensional storage facility is performed as follows. First, the spreader is suspended from the lifting frame of the stack crane, the lifting frame is lowered, the spreader is placed on the container, and the container is rotated by a twist lock mechanism provided at the four corners of the spreader. Grasp
Raise the lifting 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. The spreader runs out after the container is released, and is again suspended on the lifting frame.

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