[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box pallet for storing industrial waste, for example.

[0002]

2. Description of the Related Art Generally, in this type of box pallet, an upper part is formed into a box shape, and appropriate waste materials are stored in the box pallet. When the box pallet is taken out from the box pallet, the box pallet becomes a considerable weight including waste, so after it is lifted by a forklift or the like and transported to a predetermined site, the box pallet itself is separated by another means such as a wire. Under the present circumstances, it is currently suspended and taken out while being taken out, and a structure has been devised in which the side plates of the box pallet are opened and closed so that the waste can be taken out relatively easily.

[0003]

In the above-mentioned conventional apparatus, the box pallet itself is hung and tilted by another means, such as a wire, when the stored waste is taken out. At least two people are required, one to actually suspend wires and the other to lift and operate the box pallet using a forklift, etc. If this hinders cooperation, the suspending work is extremely dangerous. However, the operator was often injured by the corners of the box pallet, wires, etc. In addition, even if the side plate of the box pallet is opened and closed, it is very troublesome for the operator to take out the waste inside, which is very troublesome. , The box pallet itself had to be lifted up, which was a dangerous task. The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a box pallet that can effectively perform the operation of an operation member that opens and closes a bottom plate by a tilting lever.

[0004]

In order to achieve the above-mentioned object, the present invention is constructed such that the upper part is opened and the four circumferences and the bottom part are surrounded by side plates and bottom plates, and the bottom plate is divided into two parts and can be opened and closed. A box pallet, and an operating arm supported so as to be tiltable in the vertical direction with respect to the side plate,

An operating rod that is reciprocally mounted on the operating arm and that maintains the closed state of the bottom plate in the engaged state with the operating arm and allows the open state of the bottom plate in the disengaged state;
An operating member that is tiltably mounted on the side plate and that is connected to the operating rod to control the positional displacement of the operating rod.
The tilting lever is supported so as to be tiltable with respect to the side plate and tilted by means other than the operating member, and the connecting means for transmitting the tilting movement of the tilting lever as the tilting movement of the operating member. The gist is that the tilting angle of the tilting lever is linked to the operating member in an adjustable manner. Further, a connecting rod is provided on the operating member in a projecting manner, and a plurality of locking grooves for engaging and disengaging the connecting rod are formed in the connecting means, and the locking grooves are at least tilted in a state of being engaged with the connecting rod. It is preferable that the lever is set to a position that prevents tilting and a position that allows tilting.

[0005]

According to the above construction, the bottom plate is opened and closed by the tilting operation of the operating member, and the tilting operation of the operating member is performed by the tilting lever tilted by another means. Further, the tilting angle of the tilting lever is adjusted so as to be set to at least a position for preventing the tilting and a position for allowing the tilting to control the tilting state of the tilting lever.

The box pallet 1 of this embodiment is constructed as described above, and is divided into two bottom plates 3A and 3B.
In the closed state, the desired wastes and the like are put into the box pallet 1 from above and stored.

Therefore, a case where the stored wastes and the like are taken out from the box pallet 1 will be described. In this embodiment, first, the engaging grooves 33B, 33 of the operation link 30 are formed.
In the state in which any one of C is engaged with the connecting rod 34, the fork such as a forklift is inserted into the fork insertion holes 20 and 20 located substantially below the metal fittings 5 to 5 or the box pallet 1 and the fork is inserted. The entire box pallet 1 is lifted by a lift or the like to be located at a predetermined portion, for example, above the loading platform of a truck for transporting waste or the like.

Therefore, the operator rotates the operating member 18 to the side plate 2A side or the automatic operating means rotates the operating member 18 to the side plate 2A side. In order to rotate the operating member 18 to the side plate 2A side by the automatic operating means, the entire box pallet 1 is positioned slightly below the upper part of the side plate (not shown) of the truck and is pulled toward the side plate of the truck, and the automatic operating means is operated. When the abutting plate 27 of the tilting levers 26, 26 constituting the above is abutted against the side plate of the truck and pushed toward the side plate 2B side of the box pallet 1,
6, 26 are rotated clockwise in the drawing around the support pins 26a, 26a, and the bent pieces 26b, 26b at the upper ends thereof are rotationally displaced along the side end surface side of the side plate 2C. As a result, the support pins 29, 31 of the connecting arms 28, 28 and the operating links 30, 30 are pulled in the right direction in the drawing.

Then, the operating arm 7 is tilted downward (tilted downward along the side plate C) due to its own weight or the like (tilted counterclockwise in the drawing), and in conjunction with this, the operating links 8 and 8 are sequentially moved downward. The bottom plates 3A and 3B are operated to be displaced so that the bottom plates 3A and 3B are positively opened. Then, the bottom plates 3A and 3B are bidirectionally moved with respect to the side plates 2A and 2B by the actuating links 8 and 8 due to their own weight and the synergistic action due to the weight of the stored waste. The bottom of the box pallet 1 itself is opened when the box pallet 1 is opened.
This is to take out the wastes stored inside.

Then, in the state where the removal of the wastes stored in the box pallet 1 is completed as described above, the sled-shaped legs 41 of the bottom plates 3A and 3B remain in contact with the installation surface. When the entire box pallet 1 is lowered in this state, the bottom plates 3A, 3B
The respective guide wheels 22 and 25 are positively rotated in the closing direction while maintaining the contact state with the installation surface to bring the bottom surface of the box pallet 1 into the closed state.
