BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coil transfer device, and more particularly to a technique for efficiently transferring and transferring a coiled heavy object.

[0002]

2. Description of the Related Art A steel sheet wound in a coil shape, that is, a coil-shaped heavy object, produced in an iron mill or the like is several thousand
Since it will be a large weight of kilograms and the risk of dropping during transfer and transportation will increase, it is necessary to give sufficient consideration to its handling. FIG. 3 shows a state in which the fork 2 of the forklift 1 is inserted into the hole H of the coiled heavy object X and conveyed.

[0003]

However, in the case of transporting the coiled heavy object X by the forklift 1, since the coiled heavy object X is a large heavy object,
If the center of gravity moves forward from the front wheels of the forklift truck 1, it will fall, so it is difficult to increase the tooth depth of the coiled heavy object X, and even if the turning radius during transportation is reduced, the centrifugal force is reduced. The force may cause a fall. Further, it is effective to mount a heavy counterweight (weight) on the rear part of the forklift 1 to balance the weight, but the carrying load increases by the counterweight and a coiled heavy object is not mounted. Even when there is no load, the weight of the counterweight is added, and the functionality is significantly impaired.

The present invention has been made in view of the above circumstances, and is intended to prevent a fall during carrying work.
The purpose is to ensure operability during transportation.

[0005]

In order to solve such a problem, there is provided a device for supporting a coiled heavy object and carrying the heavy object, the lifter being mounted on a traveling vehicle, and being lifted and lowered on the lifter. Upper horizontal slide means, a fork portion arranged on the upper horizontal slide means for supporting the outer peripheral surface of the coiled heavy object when protruding forward, a lower horizontal slide means arranged on the lower part of the traveling vehicle, and a lower part An outrigger arranged on the horizontal slide means and brought into contact with the traveling surface of the traveling vehicle when protruding forward is adopted.

[0006]

When the coiled heavy object is lifted and conveyed, the traveling vehicle is advanced to a position in the vicinity of the coiled heavy object to be conveyed, and the outboarder is projected forward by the operation of the lower horizontal slide means so that the outrigger is projected on the traveling surface. Keep in contact. By moving the lifter up and down, the height of the upper horizontal slide means is adjusted to the vicinity of the lower position of the coiled heavy object, and the fork portion is projected forward by the operation of the upper horizontal slide means. The lifter raises the fork via the upper horizontal slide means to support the weight by bringing the fork into contact with the outer peripheral surface of the coiled heavy object, while the coiled heavy object contacts the outrigger and the running surface. By carrying out in part, it prevents the occurrence of the forward leaning phenomenon of the traveling vehicle,
By traveling the traveling vehicle in this state, the traveling vehicle is transported to the intended place. When lowering a coiled heavy object,
After advancing the traveling vehicle to a position near the unloading location, the lifter lowers the fork portion via the upper horizontal sliding means, places the coiled heavy object on the load receiving table, etc., and releases the support, The fork portion is retracted by the operation of the upper horizontal slide means. Then, the outrigger is moved backward by the operation of the lower horizontal slide means, and thereafter, the traveling vehicle is caused to travel to a target location.
