Container connection fastening block {FASTENING BLOCK FOR CONTAINER CONNECTION}

The present invention relates to a fastening block for connecting a container.

The container connection fastening block is used to connect the container and the spreader.

Here, the spreader refers to a facility that picks up and unloads containers.

In general, container spreader equipment is used to load containers.

For example, the spreader is coupled to the top of the container and is configured to move the container upward and to load multiple containers in multiple stages.

In this way, the spreader goes through a process of being repeatedly coupled and released with a plurality of containers.

Therefore, the spreader has a separate container connecting device commonly referred to as a flipper or the like.

For example, a commonly known container connection device is configured to be operably connected to a spreader in a hydraulic manner to rise and fall, and serves to guide the container to a corner position.

However, in the case of the conventional container connecting device, while being guided up and down toward the edge of the container, frequent collisions with the connecting portion occur. As a result, damage or damage of parts is caused, and maintenance or replacement is required.

As a prior art related to the present invention, there is Korean Patent Publication No. 10-1095085 (announced on Dec. 9, 2011), and a guide flipper device of a crane spreader for multi-stage loading of containers is disclosed in the prior literature.

An object of the present invention is to provide a container connection fastening block capable of elastic deformation against the impact generated when the container and the spreader are connected, thereby preventing damage and damage to the entire system as well as the crane spreader through absorption of impact force.

As shown, according to an embodiment of the present invention, the container connection fastening block 100 is made of a flexible material and is elastically deformable to the spreader 200 (see FIG. 7 ).

The container connection fastening block 100 absorbs the impact between the container and the spreader 200 (refer to FIG. 7 ), and prevents the impact from being applied to a part of the spreader or the entire system.

The container connection fastening block 100 according to an embodiment of the present invention includes a flexible body 110, an insert nut 130, an insert plate 150, and a double plate spring structure 170.

The flexible body 110 is connected to the spreader through both ends in the longitudinal direction.

As a specific example, the flexible body 110 may be made of a material capable of elastically deforming flexibly to absorb an impact force generated when the container is connected to the spreader.

As a preferred example, the flexible body 110 may be manufactured using a material such as flexible rubber (ie, rubber).

In addition, the flexible body 110 may be formed in the shape of a rectangular parallelepiped having a flat surface portion 111, a side portion 113, and a grooved surface portion 115.

The flat surface part 111 forms one surface (eg, an upper surface, etc.) of the flexible body 110 as shown in FIG. 1 and has a flat surface.

Side portions 113 are formed on both sides of the flat surface portion 111 as shown in FIG. 1.

Specifically, an insert plate 150 (refer to FIG. 2) installed inside the flexible body 110 may be disposed in parallel to face to face on the side portion 113.

It includes first and second inclined surfaces 1151 and 1152 formed inclined to both sides.

In this case, it is preferable that the first and second inclined surfaces 1151 and 1152 have the same length.

In addition, the first and second inclined surfaces 1151 and 1152 are preferably formed to be inclined to have the same inclination with respect to the flat surface portion 111 (see FIG. 5).

This is because, when the container connection fastening block 100 is elastically deformed by an external impact, it must have a shape that is symmetrical to the left and right with respect to the center of the width so that the deformation is not concentrated to one of the left and right sides of the width.

That is, it is because elastic deformation can be stably possible when an impact is applied.

Insert nuts 130 are provided at both ends of the flexible body 110 and are fastened to the spreader.

Insert nut 130 may be provided with a plurality (eg, 12, etc.) at both ends of the flexible body 110, that is, both side portions 113 (see FIG. 2).
