Description

[Detailed description of the invention] The present invention relates to a suspension device that can be used to suspend and transport cabinets, containers, etc., which can easily hook and release cabinets, etc., and has a strong The purpose is to provide a large-scale device.

Hereinafter, the present invention will be described in detail with reference to the drawings showing one embodiment thereof.

First, FIG. 1 shows a usage mode in which the suspension device 1 of the present invention is attached to a connector 2, and the suspension device 1 is attached to both ends of the horizontal portion of the connector 2, which is moved by a chain conveyor or the like stretched on the ceiling. 1 is attached to the hanging object 3, such as a container, and the object 3 to be suspended is thereby hung by the hanging handle 4 and transported to a predetermined position.

FIG. 2 shows a portion of the suspension device 1 on an enlarged scale.

Reference numeral 5 designates the main block, which has a notch 6 on its lower surface and a downward U-shaped portion 7, and one side 8 of which has a hook 9 that appears in the notch 6 facing upward and rotates around a spindle 10. Support freely.

The length of this hook 9 is set to such a length that it comes into contact with the other side 11 when it protrudes into the notch 6 as shown.

On the other hand, in order to rotate this hook 9 so as to retract it into one side 8, a drive device 12 is provided, which is constituted by a small cylinder 13 and connecting links 14, 15.

At this time, when the cylinder 13 is moving backward, the hook 9 is allowed to freely rotate within the range of angle C in both directions as shown by arrows A and B, and when the cylinder 13 moves forward, the hook 9 is forced to rotate. In order to rotate only in the direction of the arrow A so that the hook 9 is recessed into one side 8, the hook 9 is provided with a claw 16 as shown in FIGS. 3 to 5, and the connecting link 15 is The claws 17 are integrally provided so that they are brought into contact as appropriate.

Incidentally, in order to support such hooks 9 and 15, a notch is provided in one side 8 of the main body block 5.

With this configuration, when suspending the suspended object 3, first, as shown in FIG. I'm going to take it down.

Then, at this time, the claw 16 of the hook 9 is connected to the claw 1 of the link 15.
Since the hook 9 can be rotated within the range of angle C without contacting the hook 7, the hook 9 is pushed by the hanger 4 and rotates in the direction of arrow A, and the hanger 4 enters the notch 6.

When the hanger 4 fully enters the notch 6, the hook 9 automatically rotates in the direction of arrow B, comes into contact with the other side 11, and stops.

When the main body 5 is raised in this state, the hanging arm 4 comes into contact with the hook 9 and cannot be pulled out as shown in FIG. suspended.

At this time, since the hook 9 is prevented from rotating by coming into contact with the other side 11, its strength to withstand the downward force from the hanger 4 is extremely high, and a structure with a simple structure and high strength is realized. Ru.

After suspending to a predetermined position, the main body block 5 is lowered as shown in FIG. 5 to separate the hanging hand 6 from the hook 9, and in this state, the cylinder 13 is advanced.

Then, the link 15 is rotated downward, so that the claw 17
The hook 9 is rotated in the direction of arrow A by pressing the claw 16 of the hook 9, and is recessed into one side 8.

Thereafter, when the main block 5 is raised, the hanger 4 is removed from the notch 6 and can be taken out.

At this time, since it is only necessary to rotate the hook 9, the cylinder 13 may be small and simple, and the entire drive device 12 can be simplified.

As described above, according to the present invention, a notch is provided in the lower surface of the main body block, and a rotatable and retractable hook is provided therein, and when this hook protrudes, it is brought into contact with the other side, and the upper surface of the hook is brought into contact with the other side. Since the suspended object is supported and suspended, it is possible to achieve great strength, and the suspended state can be released by rotating the hook and recessing it. This allows the device to have a simple configuration.
