Description

tie device

The new model relates to a container fastening device, in particular to a fastening device.

Generally, the containers loaded on the freighter will be stacked into multiple layers. In order to prevent the container wheel from shaking while driving, which will cause the container to become unstable, most of the container tie-downs are used to tie the container to the deck or bridge. For example, TW Patent No. No. Patent cases such as No. I250956, No. M284618, No. I245730...etc.

As shown in Figures 1 and 2, the deck or bridge of a general cargo ship is provided with a plurality of fixing seats 2 for welding and fixing a plurality of eye plates, and the fixing plates 1 are welded to the fixing seats. 2, the binding plates 1 each have a plurality of circular holes 101, and most of the container binding devices 3 can be pivotally connected to the binding plates 1, respectively, and the container binding devices 3 respectively include a A turnbuckle (Turnbuckle) pivotally connected to the tie plate 1, and a Lashing Rod (Lashing Rod) adjustably locked to the turnbuckle 4, the tie rod 5 can be relative to a container 6. Container corner 601 (Corner Casting Of Container) generates hook setting.

Although the purpose of fixing the container 6 can be achieved by the above-mentioned cooperation of the binding plate 1 and the container binding device 3, as shown in Figures 3 and 4, when the hull is transported, it is subjected to the action of wind and waves, and is subjected to an impact force in the direction F (as shown by the solid arrow), the container 6 is inclined to tilt in the opposite direction (see the dashed arrow). After the tie rod 5 is pulled by the container 6, there is no buffer when the hull is impacted. The tie rod 5 is damaged by pulling (see Figure 4), and more seriously, because the pulling force of the container is eliminated, the container 6 is more likely to tilt (see the left side of Figure 4), and even cause damage to the container 6 and loss of goods .

Furthermore, when the two tie rods 5 are pivotally connected to the tie plate 1, the seam between the tie rods 5 is likely to become larger or smaller due to the change of the tie angle, so it is easy to Inadvertently pinching the operator's hand during operation.
