The above-mentioned high-temperature ingot and the container containing the molten alloy are heavy objects, and it is extremely dangerous to work in the vicinity thereof. There is concern about adverse effects on workers such as the risk of burns.In addition, if the transported object is a dust-generating nodule, it will be a poor environment such as working in a dust atmosphere.
There were various problems in terms of worker safety and hygiene. In addition, although the crane itself can be operated remotely as described above, in addition to the crane operator, another operator actually clamps or releases the ingot with a clamp near the ingot. It was necessary and there was also a problem that work efficiency was poor.

When the clamp 10 is hung by the sling 21 that is hooked on the hook 20 of the crane, the tension, which is the weight of the clamp 10, is applied to the pair of arms 1 and 2, and the pair of links 11 and 12 has the F shown in FIG. The force of 1 , F 2 acts,
Since the links 11 and 12 are pivotally supported by the pin 15, F
The horizontal component forces F 3 and F 4 of 1 and F 2 cancel each other and are converted into the driving force of the vertical movement m u or m L of the pin 15, F 1 and F 2 respectively. The vertical components F 5 and F 6 of the clamp 10 function as a reaction of the own weight of the clamp 10. Further, when the opening angle of the pivot portion of the arm formed by the links 11 and 12 on the pin 3 side becomes 180 degrees or more, the movement m L of the pin 15 on the pivot portion of the arm to the pin 3 side is driven, and the link 11
The lower part of the tip of the abutment abuts the stopper projection 16 of the link 12, and the movement m L is stopped and the rotation is locked.
At pin 1 of this locked link 11 at
The angle between the straight line connecting 3 and the pin 14 of the link 12 and the straight line connecting the pin 13 and the pin 15 is θ, and θ = 5 to 10
By setting the angle to °, it is possible to prevent the link from jumping up and releasing the lock due to an unexpected external force.

The clamps 4 and 5 of the clamp 10 are opened and moved to a predetermined position while the lock is operating.
After being stopped on the transported object and lowered, the pair of links 11 and 12 are unlocked by using the opening jig 30, and the transported object 31 is sandwiched between the sandwiching portions 4 and 5, and When the clamp 10 is hung by the sling 21 that is hooked on the hook 20 of the crane as shown in Fig. 5, the horizontal component force F 3 , F 4 of the tension of the clamp 10 acts on the transported object 31 via the projections 6 and 7. However, this serves as a frictional force and can grip the transported object 31 of the heavy object, and further, the own weight of the clamp 10 and the transported object 3
The gravity added with its own weight of 1 acts as tension, and the horizontal component forces F 3 and F 4 are further increased. When the heavy object to be conveyed 31 is transferred and landed on a fixed floor or the like at a predetermined position, the heavy object loses its own weight, and the object to be conveyed 31 is located above the protrusions 6 and 7 of the clamps 4 and 5 of the clamp 10. Abutting on each other, and sandwiching between them,
Further open, the pair of links 11,1
When connecting the self-weight of 2 or the jig 30 for opening, the weight of the jig 30 is also added, and as shown in FIG. 1, the pair of links 11 and 12 should be locked after the sandwiching portions 4 and 5 are opened to the maximum extent. become.

According to the present invention, a pair of links are arranged between a pair of arms which constitute a clamp for suspending a crane for carrying heavy objects such as an ingot and a molten alloy container, and a required opening angle of the clamp. By holding an open / close lock mechanism that locks so that the lock is held, and this lock can be easily released by a rod-shaped jig that engages with the link, the normal crane The so-called clamping work can be performed by one person at the wired remote controller position, that is, the work to be carried can be clamped or released, and the work can be transferred, and a safe and good working environment can be maintained.
