Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a structure of an opening / closing hook.

[0002]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an opening / closing hook which allows a rope attached to the hook to be automatically removed with a tip tool of a manipulator.

[0003]

According to the present invention, there is provided an opening / closing hook having a flange provided with a hole through which the shaft can be loosely inserted, on the protruding portion of the shaft provided with a protruding portion at the lower end. A separate flange is fixed to the upper end of the shaft, and a lower spring is mounted between the two flanges, and a spring is urged to always push down the lower flange.
A hook is attached to the lower end of the shaft so as to be vertically rotatable, and a stopper for opening and closing the opening of the hook is attached to the neck of the hook so as to be vertically rotatable.
A rope feeder rotatably mounted on the stopper, the other end rotatably mounted on the flange, and further extending to the rear side of the hook at the rear end of the projecting portion of the shutter; With the metal fittings attached, under normal conditions both flanges are always open due to the spring force of the spring,
The opening of the hook is closed by the stopper, and then the flange is mechanically sandwiched by a tip tool of a manipulator, and the lower flange is moved upward against the spring force of the spring. When the arm is brought into contact with the upper flange, the arm rotates and moves the stopper upward to open the opening of the hook, and the opening of the hook is positioned at the position of the rope delivery metal fitting. , The rope attached to the hook can be automatically sent out.

[0004]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a projecting portion 1 of a shaft 2 having a projecting portion 1 at a lower end portion is shown. A flange 3 having a hole through which the shaft 2 can be loosely inserted is mounted on the upper part, a flange 4 is fixed to the upper end of the shaft 2, and a lower flange 3 is always provided between the upper and lower flanges 3, 4. Attach the spring 5 urged to push down,
A hook 6 is attached to the lower end of the shaft 2 so as to be vertically rotatable, and a stopper 7 for opening and closing the opening of the hook 6 is attached to the neck of the hook 6 so as to be vertically rotatable. 7, and the other end is
At the rear end of the protruding portion 1 of the shutter 2 is attached a rotatable metal fitting 9 extending to the rear side surface of the hook 6.

In the normal state, as shown in FIG. 1, the upper and lower flanges 3 and 4 are always opened by the spring force of the spring 5, the opening of the hook 6 is closed by the stopper 7, and the hook 6 is closed. Rope 10 attached to
Are not detached from the hook 6.

Next, as shown in FIG. 2, the upper and lower flanges 3 and 4 are mechanically sandwiched by a tip tool of a manipulator or the like, and the lower flange 3 is moved upward against the spring force of the spring 5. To the upper flange 4
The arm 8 rotates and moves the stopper 7 upward to open the opening of the hook 6, and the opening of the hook 6 moves to the position of the rope delivery metal fitting 9. Then, the rope 10 attached to the hook 6 can be automatically sent out by the rope sending-out fitting 9. In FIG. 1, reference numeral 11 denotes a shackle, and reference numeral 12 denotes a suspended load.

[0007]

Since the present invention is constructed as described above, the rope for hanging loads attached to the hooks can be prevented from coming off by remote control with the tip tool of the manipulator. The opening and closing of the stopper for opening and closing can automatically remove the rope from the hook.
