Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container delivery stand for carrying out container loading / unloading work by a self-propelled carriage.

[0002]

2. Description of the Related Art Conventionally, container loading and unloading of ships is performed by a lift-on lift-off method using a crane.

[0003]

[Problems to be Solved by the Invention] Conventionally, in the container yard, conventionally, the containers are individually transported to the container crane on the quay by straddle carriers, trailers, etc., and as they are transported, the distance becomes longer, and the cargo handling time is delayed. It is one of the causes. The roll-on-roll-off cargo handling method using a container trailer is also an individual container loading, and even if there is a trolley that can load multiple containers as a lot, there is a problem how to load it in a short time.

The present invention has been proposed in view of such circumstances, and economically transports a large number of containers in a labor-saving, labor-saving and safe manner so as to be loaded from the quay and landed from the quay. The purpose is to provide a container delivery stand that can be done.

[0005]

To this end, the present invention provides a pair of left and right long parallels which are erected parallel to each other on the upper surface of the quay at regular intervals which are slightly shorter than the length of the container, and which extend in the front-rear direction isometrically. A belt conveyor comprising a rail and a long endless belt which is arranged along each of the long parallel rails on a vertical vertical plane and is controlled by remote control, and an inner rectangle of the pair of long endless conveyor belts. It has a rectangular platform that is slightly narrower than its width, and has means for raising and lowering the upper surface of the platform between a lower level slightly lower than the upper surface of the conveyor belt and an upper level slightly higher than the upper surface of the conveyor belt. It is equipped with an unmanned self-propelled carriage that stops, steers, and moves up and down.

[0006]

With this configuration, the containers stacked on the conveyor belt by the container crane are driven by the drive device to the rear end of the container platform (the loading position of the container cart) in units of lots loaded by the self-propelled cart,
Moved sequentially. The length of the container mount shall be determined so that it can accommodate at least one bay container of the container ship. Further, the height of the container loading of the container base is determined so as to be lower than the upper limit position where the self-propelled carriage is raised by the lifting link device and higher than the lower limit position where the self-propelled carriage is lowered by the lifting link device. Therefore, the self-propelled carriage can enter under the container on the container frame, and the self-propelled carriage can be lifted by the lifting link device to load the container lot. After that, the driving device moves the subsequent container to the position where the container is loaded on the container platform, and the transport distance of the self-propelled vehicle is shortened. The procedure is reversed for unloading from a ship.
