Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a lashing device for warehouse containers.

Conventional structure and its problems Containers loaded in the hold of a cargo ship are subject to excessive loads in the horizontal and vertical directions due to ship motion, but if this load exceeds a certain tolerance, safety may be compromised. Therefore, it is necessary to limit container overlap.

Conventionally, as shown in FIG. 1, when loading containers 3 into a hold 2 of a ship's hull 1, the containers 3 are stacked in multiple stages, and adjacent containers 3 are connected to each other by a connecting device (not shown). In order to reduce the excessive load caused by the movement of the container, a lashing device 5 is provided in the lateral direction, and if necessary, the lower part of the container 3 is lashed with a wire 4 or the like.

However, since the containers 3 are generally stacked in multiple tiers, the load not only in the horizontal direction but also in the vertical direction cannot be ignored, but the conventional method described above cannot reduce the load in the vertical direction, and therefore the weight of the container must be limited. It was hot. Further, the installation work of the horizontal lashing device 5 is dangerous due to its installation position, and there has been a demand for a reduction in the work.

OBJECTIVE OF THE DEVICE The present invention aims to overcome the above-mentioned drawbacks of the conventional device, and to provide a securing device for containers inside a cargo hold that can reduce the vertical load on the containers caused by ship motion.

Composition of the Invention In order to achieve the above object, the lashing device for warehouse containers of the present invention has one end engaged with a hatch cover,
The other end engages with the topmost container in the hold and is equipped with a length adjustment section.

With this configuration, the vertical load on the container caused by ship movement can be reduced, and therefore, in combination with the lateral securing devices, it is possible to load the containers in the hold while keeping them fully loaded, or the lateral securing devices can be made smaller, thereby reducing dangerous work.

Embodiment and Operation An embodiment of the present invention will be described below with reference to FIGS. 2 to 4.

Figure 2 is a schematic cross-sectional view of a warehouse using a lashing device for containers in a warehouse according to an embodiment of the present invention, Figure 3 is a schematic longitudinal sectional view of the same, and Figure 4 is a container in a warehouse according to an embodiment of the present invention. A front view of the lashing device,
Components that are the same as those in FIG. 1 are given the same reference numerals and their explanations will be omitted.

In FIGS. 2 to 4, reference numeral 6 indicates a lashing device according to an embodiment of the present invention, 7 indicates a hatch cover, and 8 indicates a manhole provided in the hatch cover 7. The lashing device 6 includes a turnbuckle 9 and a hook 10 attached to one end of the turnbuckle 9.
and a chain 11 attached to the other end of the turnbuckle 9. The hook 10 is engaged with a hook 12 fixed to the hatch cover 7, and the chain 11 is engaged with a hook 14 fixed to a connecting device 13 that connects horizontally adjacent containers 3, 3 to each other. It matches. The coupling device 13 engages with a corner fitting 15 fixed to a corner of the container 3.

Hereinafter, the effects of the above configuration will be explained. When installing the lashing device 6, a worker enters between the hatch cover 7 and the uppermost container 3 through the manhole 8, and attaches the hook 10 to the hook 1.
2 and passing the chain 11 through the hook 14, turn the turnbuckle 9 to shorten its length. As a result, the hook 10 is attached to the hook 12.
In addition, the chains 11 are firmly engaged with the hooks 14, and tension is applied to the lashing device 6, so that the lashing is securely performed.

Since the lashing device 6 is provided in this way, it is possible to reduce the vertical load acting on the container 3 due to the movement of the ship, and in combination with the horizontal lashing device 5, the container 3 can be secured in the hold in a fully loaded state. 2 can be stacked in multiple stages. Alternatively, the horizontal lashing device 5 can be downsized to reduce dangerous work. Note that since the vertical lashing device 6 can operate on the topmost container 3, it is extremely safer than the lateral lashing device 5.

FIG. 5 is a front view of a lashing device in another embodiment, in which the lashing device 16 includes a turnbuckle 17.
and hooks 18 integrally formed at both ends thereof,
19, which engages the hook 19 with the corner fitting 15.

In the above embodiment, the lashing devices 6, 16
Although an example has been described in which the electrodes are provided along the vertical direction, it goes without saying that they may be provided diagonally so as to alternately cross each other.

In addition, in FIGS. 4 and 5, the corner fittings 15 are shown with dashed lines in order to make the drawings easier to understand.

Effects of the invention As explained above, according to the invention, the vertical load acting on the container due to the movement of the ship can be reduced, and in conjunction with the lateral lashing device, the container can be safely loaded into the hold while fully loaded. It can be stacked in multiple stages, or the horizontal securing device can be downsized to reduce dangerous work.
