Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention... This invention relates to a two-tier hanging container cargo handling device.

(Prior Art) Cargo handling of maritime shipping containers is mainly carried out at dedicated wharves. At that time, a lifting hook was inserted into a cone placed at each corner of the container using a container-specific crane. 9
Rotate 0° and engage the lifting hook with the cone. The containers are lifted one by one.

(Problem to be solved by the invention) The increasing size of container ships and the correspondingly larger dedicated gantry cranes lead to an increase in the number of containers to be handled and an increase in the round trip distance for cargo handling, resulting in an increase in cargo handling time per ship. ing. On the other hand, depending on the type of cargo inside, the containers handled may have a light specific gravity, and in that case, the specific gravity of the container may be light compared to the capacity of the crane. In terms of weight, two conveyors can be raised and lowered at the same time. However, land transportation of containers usually involves one container (sometimes two columns) per truck platform.
Because it is. In order to stack containers in two layers and load them simultaneously using a conventional container crane, it is necessary to connect the two containers vertically using twist locks, etc., but this work is carried out by workers on the ground. The problem is that it takes time and effort and is not efficient.

The present invention has been proposed in view of the above-mentioned problems, and its purpose is to efficiently connect two containers vertically using twist locks.
The object of the present invention is to provide a tiered container cargo handling device.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a flexible container that is housed in an upper cone and a lower cone that are attached to the upper and lower corners of a two-tier hanging container. A hook rotation transmission mechanism for a two-tier hanging container is constructed by the rotating upper clutch and lower clutch, a connecting rod that connects these clutches, and a ratchet mechanism interposed in the middle of the connecting rod, and is inserted into the upper cone. A two-stage hanging hook is constructed by a hook that rotates and engages with the upper cone, a rotating shaft attached to the hook, and a rotation drive device for the rotating shaft. a lower hook that is inserted into the attached upper cone and rotates to engage with the upper cone; and an upper hook that is inserted into the lower cone of the two-tier hanging container and then rotates and engages with the lower cone; This constitutes a two-stage suspension twist lock, and the two-stage suspension hook is suspended and supported by a crane.

(Function) The two-tier hanging container cargo handling device of the present invention is configured as described above, and the crane is operated to lower the hook,
Insert the hook into the upper cone of the container for tiered lifting, engage the hook with the upper clutch, then rotate the hook, upper clutch, and upper part of the connecting rod 90 degrees in one direction to use the same hook for tiered lifting. After engaging the upper cone of the container, operate the crane to lift the two-tiered container, then operate the crane to lower the two-tiered container onto the regular container, and lift the two-tiered container onto the normal container. Insert the upper hook of the twist lock for tiered lifting into the lower cone of the tiered lifting container, engage the upper hook with the lower clutch, and then connect the hook, the upper clutch of the tiered lifting container, the connecting rod, and the lower cone. Rotate the clutch and the upper and lower hooks of the two-tier lifting twist lock 90 degrees in the other direction to engage the upper hook of the two-tier lifting twist lock with the lower cone of the two-tier lifting container, and The lower hook of the tiered twist lock engages with the upper cone of a regular container.

(Example) Next, the two-tier hanging container cargo handling device of the present invention will be explained with reference to an embodiment shown in Figs.

It is composed of. In addition, the above two-stage hanging hook (a
) consists of a hook (5) that rotates after being inserted into the upper cone (6) and engages with the upper cone (6), a rotating shaft (2) attached to the hook (5), and a rotating shaft (2) attached to the hook (5). It is composed of a rotational drive device (cylinder) (3) for a rotating shaft (2). In addition, the twist hook (c) for two-stage hanging is inserted into the upper cone (13) attached to the upper corner of the normal container (B), then rotates and engages with the upper cone (13). Lower hook (12) and the above two-tier hanging container (^)
and an upper hook (11) that rotates and engages the lower cone (10) after being inserted into the lower cone (10). The two-stage hanging hook (a) is suspended and supported by a crane (not shown). In addition, since the connecting rod (8) passes vertically through each corner of the two-tier hanging container (A), two connecting rod protection cases (not shown) are required.
It is attached to each corner of the tiered container (A).
