[Problems to be solved by the device]

In the case of the above-mentioned conventional lifting device having a tension spring for preventing hooks from disengaging, since the steel rope is used, the container is in line contact with the container which is the object to be transported, and when the weight of the container becomes heavy, the container deforms. There is a risk of

This device can lift and transport heavy containers,
The present invention relates to a container suspender having a tension spring for retaining hooks that can prevent the container from being deformed.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, in the container hanging device having the tension spring for hook disengagement of the present invention, two strip body spacing members 1 extending in the front-rear direction are arranged at intervals in the left-right direction, The intermediate portions of the hanging strips 2 are engaged with both sides of the strip spacing members 1 in the longitudinal direction, the container engaging hooks 3 are connected to the lower ends of the hanging strips 2, and the upper portions of the hanging strips 2 are connected. Are connected to the suspension ring 4, and the left and right strip body spacing members 1 are linked via tension springs 5, and the strip body positioning stoppers 13 at both ends of each strip body spacing member 1 and the strip body spacing member 1 are connected. The intermediate portion of the suspension strip 2 is disposed between the strip positioning stopper 12 fixed to the end of the suspension strip 2.

[Action]

By grasping and pulling downward the container engaging hooks 3 attached to the lower ends of the left and right suspension members 2, the tension springs 5 are extended, and the left and right container engaging hooks 3 are hooked in the lower container 8. Engage the mating portion 9. In this way, even if the hook 3 is released, the tension of the tension spring 5 keeps the hook 3 engaged with the hook engaging portion 9.

〔Example〕

 Next, the present invention will be described in detail with reference to the illustrated example.

FIGS. 1 to 4 show an embodiment of the present invention, in which two metal pipes 10 extending in the front-rear direction are arranged in parallel in the left-right direction at intervals. On both ends of 10, a strip positioning stopper 12 having a spring connecting portion 11 and a strip positioning stopper 13 are arranged at intervals in the longitudinal direction of the tubular body and fixed by welding. The strip body spacing member 1 is constituted by the stoppers 12 and 13 fixed by.

Stoppers 12 and 1 on both ends of each strip spacing member 1
3, the intermediate portion of the belt-shaped suspending strip 2 made of a synthetic fiber knitted fabric is arranged, and the short attachment belt 14 made of a synthetic fiber knitted fabric cooperates with the suspending strip 2 to form a pipe. Body 1
It is arranged so as to sandwich 0, and both ends of the mounting belt 14 are joined to the hanging strip 2 by sewing, and the intermediate portion of the hanging strip 2 is attached to the hanging strip 2 by the mounting belt 14. It is attached so that it does not move in the longitudinal direction of the strip member 1 on both ends.

Each hanging strip 2 hanging from the strip spacing member 1
The lower end portion of the hanging hook 3 is wound around the upper horizontal rod of the metal container engaging hook 3, the overlapping portion of the lower end of the hanging strip 2 is joined by sewing, and the upper end of each hanging strip 2 is made of metal. It is wound around a suspension ring 4 and the overlapped portion at the upper end of the hanging strip 2 is joined by sewing. Further, both end portions of each strip spacing member 1 are attached to the spring connecting portion 11 by a pulling member. It is connected via a spring 5.

When the container lifting device according to the embodiment of the present invention is used to lift and transport an even number of, for example, four containers stacked in two rows and two stages, as shown in FIG. By holding the container engaging hook 3 attached to the lower end of the hanging strip 2 and pulling it downward,
While extending the tension spring 5, the left and right container engaging hooks 3 are attached to the hook engaging portions 9 of the lower container 8.
Engage with. In this way, even if the hook 3 is released, the tension of the tension spring 5 keeps the hook 3 engaged with the hook engaging portion 9.

Next, as shown in FIG. 6, the hanging hooks 15 in a carrying machine such as a chain block or a crane are engaged with the hanging ring 4, and they are stacked in two rows and two stages by the carrying machine.
The individual containers 8 are hoisted and transported.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

By grasping and pulling downward the container engaging hooks 3 attached to the lower ends of the left and right suspension members 2, the tension springs 5 are extended, and the left and right container engaging hooks 3 are hooked in the lower container 8. When engaged with the engaging portion 9, even if the hook 3 is released, the tension of the tension spring 5 pulls the hook 3 upward so that the hook 3 is held so as not to be disengaged from the hook engaging portion 9. The container engaging hooks 3 capable of simultaneously hoisting and transporting the containers 8 together and engaging with the hook engaging portions 9 of the adjacent containers 8 are attached to both sides in the longitudinal direction of the strip spacing member 1. Since the hanging strip 2 is connected to the lower end of the hanging strip 2, the portion of the hanging strip 2 facing the side surface of the container is made substantially vertical, and the hook 3 is opposed to the hook engaging portion 9. It can be engaged in the correct state as not to tilt Te.

Further, particularly in the case of the present invention, since the hanging strip 2 is used as the hanging member, even if a heavy container 8 is lifted, the hanging strip 2 and the container 8 come into contact with each other over a wide surface. There is no risk of deformation of the strip 8, and the strip positioning stopper 13 and the strip positioning stopper 12 hold the intermediate portion of the hanging strip 2 so as not to move in the longitudinal direction of the strip spacing member 1. Thus, the intermediate portion of the hanging strip 2 can be stabilized.
