Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cargo transportation auxiliary device, and more particularly to a cargo transportation auxiliary device suitable for loading and unloading heavy cargo into a container.

[0002]

2. Description of the Related Art Conventionally, when a heavy cargo is loaded or unloaded in a container, a cargo handling work using a forklift truck or a cargo handling work using a crane is performed. That is, for cargo handling work that is not too heavy and is not too bulky, it is possible to load and unload it in a container by using a forklift car, and conversely, if the weight is large or For cargo handling of bulky cargo, a crane can be used to load and unload containers. Of course, a crane can also be used for the former cargo handling work.

Further, when carrying out cargo handling work using a forklift car, loading and unloading of cargo to and from dry containers can be carried out, but when carrying out cargo handling work using a crane, cargo to dry containers can be loaded and unloaded. It is not possible to perform loading and unloading work, and loading and unloading of cargo in an open top container or the like whose upper surface can be opened.

[0004]

However, there are strong demands for ensuring the safety of cargo during transportation and temporarily storing the cargo after transportation, and the cargo which should satisfy such requirements. Since the number of types of containers is increasing, it is necessary to adopt a dry container that is significantly more confidential than open-top containers, has a high cargo protection effect against wind and rain, and that can easily achieve stacking. Is preferred. Therefore, although it is preferable to load a large or bulky cargo in a dry container, as described above, it is almost impossible to pack such a cargo in a dry container.

To explain this point in more detail,
When carrying out cargo handling work using a forklift car, it is necessary to lift the cargo to some extent by the forklift car and to drive the forklift car into the dry container in this state. Therefore,
Only cargo that is lower than the internal height of the dry container can be loaded. Further, since holding of the lifted state of the cargo by the forklift car is unavoidably held by a cantilever, if the total length of the cargo becomes too long, the lifted state cannot be held by the forklift car. Further, since the maximum liftable weight of the forklift truck is set in advance, it is impossible to lift a cargo exceeding this weight.

As a result, it becomes impossible to use a forklift car for loading cargo other than cargo satisfying all the above restrictions. Moreover, some of the above restrictions similarly occur when the cargo is transported to a target position other than the container (for example, a storage position in a warehouse).

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a freight transport assisting device capable of significantly increasing the types of freight that can be loaded in a dry container using a forklift truck. It is intended to be provided.

It is attached to a predetermined position of a frame body provided at a predetermined lower position of a cargo support member having a connection metal receiving member that accommodates the connection metal provided at the position.

[0010]

According to another aspect of the present invention, there is provided the cargo transportation auxiliary device, which has a cylindrical outer casing of a predetermined length that surrounds a predetermined range of the outer circumference of the cylindrical central shaft, and has a space between the central shaft and the outer casing. A rotation smoothing mechanism having an auxiliary shaft having an outer diameter corresponding to the difference between the outer diameter of the central shaft and the inner diameter of the outer casing is provided at a predetermined position on the lower surface of the first elongated member, and the central shaft is in the lateral direction. In addition to the weight of the cargo and the weight of the cargo bearing member, a plurality of them are provided at predetermined positions on the upper surface of the first elongate member with their central axes oriented in the longitudinal direction. The resulting load is distributed over the entire length range of the plurality of auxiliary shafts, and smooth rotation of the outer casing with respect to the central shaft can be achieved. Therefore, it is possible to easily transport the cargo together with the cargo support member by providing a substantially horizontal external force to the cargo support member or the cargo without providing a guide rail for guiding the cargo transport auxiliary device. Then, the cargo can be transported together with the first long member in the longitudinal direction of the first long member by the rotation smoothing mechanism provided in the lower portion of the first long member, and with respect to the first long member.

In particular, even if the destination of the cargo is inside the dry container, the cargo can be moved almost horizontally without being lifted up. Can be increased. In addition, even a very heavy cargo can be easily loaded inside the dry container without using a crane.

According to the second aspect of the present invention, the first long member has a vertically downward skirt portion, and one outer surface of the pair of skirt portions extending in the longitudinal direction. Since a plurality of rotation smoothing mechanisms are provided at predetermined positions so that the central axis is oriented vertically, the rotation smoothing mechanism should be located outside the vertically extended position of the outer surface of the cargo. Even if the cargo can be moved diagonally by supporting the cargo, it will approach the side wall of the container more than necessary and deform or destroy the side wall of the container in the worst case. It is possible to prevent the occurrence of inconvenience.

According to another aspect of the present invention, there is a second long member detachably supported by a plurality of rotation smoothing mechanisms provided at predetermined positions on the upper surface of the first long member. In addition, the second elongate member has a vertically downward skirt portion in order to regulate the sliding range of the second elongate member by the rotation smoothing mechanism, and the second elongate member is provided at a predetermined position above the second elongate member. The lower surface of the supported cargo has a connecting metal fitting receiving member for accommodating the connecting metal fitting provided at a predetermined position. The lower part of the cargo supporting member is mounted at a predetermined position on the frame body. The sliding between the cargo and the first elongate member can be achieved by the second elongate member, and the inconvenience that the cargo is strongly pressed against the side wall of the container can be greatly reduced. Moreover, the type of applicable cargo can be increased by interposing the second long portion.
