[0002]

2. Description of the Related Art Conventionally, loading work of pig iron and scrap has
Cargo handling by magnets was the mainstream. In this case, the work process involves lowering the pig iron and scrap etc. which have been transported to the quay by the vehicle once on the ground, then adsorbing the scrap etc. by an electromagnet attached to the wire of the crane and lifting the crane onto the ship. It was to turn and load. Other loading operations used rarely polyps and mocktails.

[0003]

In conventional cargo handling with a magnet, the amount of scrap that can be attracted at one time is at most about 1 ton due to the attraction capacity of the electromagnet, so that there is a problem that the cargo handling efficiency is low. . In addition, since the load such as scrap is lifted only by the attraction force of the magnet, the load may be dropped during turning of the crane due to unexpected impact or the like, and improvement in safety is desired. I was Further, there is a problem that the ship is damaged by the drop and the load is buried in the sea. In addition, since pig iron, scraps, and the like, which have been transported to the quay by the vehicle, are once lowered to the ground, there is a problem that dust soars and deteriorates the working environment.

[0004] It is an object of the present invention to provide an automatic hook device and a loading device that have high cargo handling efficiency, are less likely to accidentally drop a load, and can further improve the working environment.

[0007]

According to the automatic hook device of the present invention, the hook is automatically hooked and released by simply moving the hook integrated with the arm up and down. That is, in a state where the support is raised with respect to the base and the arm is pulled up to a position where it comes into contact with the arm guide, the arm is forcibly rotated substantially horizontally. In this state, the base, that is, the whole body, is moved onto the object to be lifted and fixed at a predetermined height. At this time, the hooked portion of the object to be lifted, that is, the trunnion and the respective positions of the hook portion are made to correspond to each other. Next, when the support is lowered with respect to the base and the arm is lowered to a position where the arm does not contact the arm guide, the hook rotates by its own weight and hangs down in the vertical direction. The positions of the trunnion and the hook portion of the object to be lifted correspond to each other, but the hook portion hangs vertically by the rotation so that the hook portion reaches the lower side without colliding with the trunnion. be able to. In this state, if the entire substrate is lifted, the object to be suspended is automatically hooked. On the other hand, the release of the hook state is as follows. First, the entire base is lowered to place the object to be lifted on a table or the like, and then the whole base is lowered slightly so that the hook portion is separated downward from the trunnion. If the entire base is pulled up in this state, the hook portion will catch on the trunnion. In the present invention, only the support is pulled up in this state. Thereby, the arm portion is guided by the arm guide portion, and the hook portion is rotated in the horizontal direction. If the entire base is pulled up in this state, the hook can be released because the hook does not catch on the trunnion.

According to the loading device of the present invention, the scraps and the like can be dropped from the vehicle on the quay near the ship with the scraps and the like kept in the transport container, and can be easily lifted and loaded by the hanging tool provided with the automatic hook device. Here, since the loading capacity of the transport container can be easily increased, the use of a large transport container can greatly increase the amount of shipping per operation, and improve the cargo handling efficiency. In addition, since the scrap and the like are not lifted by the attraction force of the magnet, but are lifted in a container, the scrap is less likely to be accidentally dropped. Furthermore, since the scraps and the like are dropped on the quay in the state of being put in the transport container, dust does not soar.
