DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container support device for preventing a container stacked and mounted on a hatch cover of a container ship having a hatch cover from laterally shifting.

[0002]

2. Description of the Related Art FIG. 12 is a perspective view showing the inside of a hold of a container ship. The container ship a that transports the container e normally stacks the container e on the hatch cover d that closes the inside of the hold b and the opening f of the deck. The hold b has a cell guide c for guiding the loading of the container e and preventing the loaded container e from laterally shifting. Conventionally, since there is no cell guide on the hatch cover d, the container e is fixed by a lashing hardware having a turnbuckle (not shown), and the upper and lower connecting hardware is used by using holes (not shown) at four corners of the upper and lower surfaces of the container e. By connecting the upper and lower containers e, the lateral displacement of the container is prevented. g is a cross deck.

[0003]

However, lashing by lashing hardware requires a heavy turnbuckle to be manually carried and mounted and rotated, which poses a safety problem. Furthermore, since the connection of the upper and lower containers by the upper and lower connection hardware is used at the four corners of all the containers,
Since the number of installations is large, and the work is performed at narrow places and at high places, there is a problem that the efficiency of container handling work is reduced.

The present invention has been made in order to solve the above-mentioned problems of the prior art. By providing a container guide in the longitudinal direction of the container on the cross deck before and after the opening, the container guide is provided. An object of the present invention is to provide a container support device that prevents lateral displacement of a container during navigation, eliminates the need for securing work by lashing hardware, etc., facilitates the loading and unloading of containers, and improves the efficiency of cargo handling. It is assumed that.

[0005]

According to the present invention, there is provided a container supporting apparatus for preventing lateral displacement of containers stacked in multiple rows and multiple stages on a hatch cover of a container ship. When moving upward through a plurality of support columns that are erected at predetermined intervals facing the upper side and moved up and down through links mounted inside and below the support columns, the support columns have moved downward along the support columns. A guide metal that is vertically erected so as to move away from the support column, and a bracket that is provided so as to protrude inward from the lower end of the support column and supports the guide metal when the guide metal moves downward. And a hook that is provided so as to be able to protrude and retract inward from the upper end of the support pillar, and that holds the guide hardware in that state when the guide hardware moves upward, and each guide hardware corresponds to each support pillar. Standing A plurality of parallel pillars, a brace connecting between the pillars, and a partition plate protruding from the inside of each pillar and partitioning between four corners of adjacent containers, the upper part of each guide hardware. Provides a container support device provided with a tightening device for fixing four corners at the lower part of the uppermost container.

According to a preferred embodiment of the present invention, after the guide hardware moves downward and is supported on the bracket, the protrusion at the lower end of each guide hardware and the protrusion of each support column supporting the guide hardware are provided. A plurality of pins that fit into the connection holes provided in the support pillar, and the pins are provided on a long axis that is disposed so as to penetrate a support member provided inside each support column, and the long axis is set to be long. Each pin is simultaneously fitted into the connection hole by sliding in the direction by the cylinder, and fixed.
When the guide metal moves upward, a fixing device is provided for simultaneously pulling out each pin from the connection hole.

According to another preferred embodiment of the present invention,
When the hatch cover is put on the opening, guide plates for guiding the hatch cover in contact with the partition plate of the guide metal moved upward are provided at the four corners of the hatch cover.

Next, the operation of the present invention will be described. When storing containers in the hold, the links attached to the top and bottom inside the support pillar so that they fit along the inside of the support pillar erected at a predetermined interval facing the cross deck before and after the hold mouth The guide hardware fixed via the hooks is slightly lifted by the container crane, the hooks are removed, and the guide hardware is suspended by the container crane so that the lower end of the guide hardware is placed on the bracket. The guide hardware is vertically collinear with the container guide disposed in the hold, and the container is suspended from the upper end of the guide hardware in the hold using the guide hardware and the container guide as a guide. When the storage of the container in the hold is completed, the guide hardware is lifted by the container crane, moved to the support pillar side via the upper and lower links, and the hook of the support pillar is hooked on the guide hardware to hold the guide hardware on the support pillar. In such a state, the hatch cover is lifted by the container crane, and the guide hardware is hung from the upper end of the guide hardware to the warehouse opening as a guide to cover the warehouse opening. The guide hardware is slightly lifted again by the container crane, the hook is detached from the guide hardware, moved to the inside of the support column, and the lower end of the guide hardware is placed on the bracket. After the guide hardware is moved to the inside of the support pillar in this way, the container is transported by a container crane, suspended while being guided by the guide hardware, and stacked and placed on the hatch cover. When the loading of the container on the hatch cover is completed, the four corners on the lower side surface of the uppermost container are fixed by a tightening device provided at the upper end of the guide hardware. Since the container is restrained at the four corners by the guide hardware and is fixed by the tightening device at the upper part of the guide hardware, there is no occurrence of lateral displacement or lifting. On the other hand, when removing a container from the hold, first remove the container on the hatch cover with a container crane, then move the guide hardware to the support pillar side with the container crane, hook the support pillar hook on the guide hardware, and remove the guide hardware. After holding on the support column and removing the hatch cover by the container crane, the guide hardware is moved inside the support column by the container crane, and the container is taken out using the container guide in the hold and the guide hardware as a guide.
