Description

[Detailed description of the invention] <Industrial application field> The present invention deals with lumps and powders generally called bulk materials.

This product relates to a container device for transporting objects such as granules, and more specifically, relates to a container device capable of transporting such bulk materials to a desired position within the range of movement of a traveling cart. It is.

<Prior Art> When transporting materials such as lumps of ore, coal, limestone, grains, salt, sugar, etc., a belt conveyor equipped with a trough is generally used.

For example, in steel mills, thermal power plants, etc., ore, coal, etc., transported by bulk carriers are unloaded and stored in piles in storage yards. In order to carry out such cargo handling work, a conhairing device as shown in FIG. 5 is provided.

This conveyor device includes a rail 51 laid in parallel, a truck 52 running on the rail 51, and a drive roller 53 and a tail roller 54 that are provided along the rail 51 and over the entire running range of the truck 52. A conveyor belt 55 which is conveyed in the direction of the arrow; an inclined conveying section 56 configured on the trolley 52 with a predetermined inclination angle; It is constituted by a conveyor 57 that conveys in a direction different from the traveling direction of the trolley 52.

According to the conveyor device configured as described above, bulk materials supplied by an unloader or other conveyor or the like on the upstream side in the direction of the arrow are transported to the conveyor 57 provided on the trolley 52 within the traveling range of the trolley 52. It is possible to store bulk goods in piles according to their height, and it is possible to carry out bulk cargo handling in a rational manner.

Furthermore, conveyor devices capable of conveying the above-mentioned bulk materials or fluids such as muddy water along steep slopes including vertical ones are known (Japanese Patent Publication No. 56-3288, etc.).

This conveyor device overlaps two conveyor belts disposed facing each other, wraps the conveyed object between these belts, and conveys the object vertically, diagonally, or obliquely.

According to the above-mentioned conhair device, it is possible to reduce the occupied floor space and transport objects from a low place to a high place or from a high place to a low place.

<Problem to be solved by the invention> In the conveyor device shown in FIG.
When conveying bulk goods etc. to a high place by tilting the conveyor belt 5, the inclination angle is set by the coefficient of friction between the conveyed bulk goods and the conveyor belt 55. In other words, the material, shape,
Alternatively, the inclination angle of the conveyor device is set depending on the particle size of the bulk material.

Generally, the inclination angle of the conveyor device is set to 15 degrees or less.

In the above conveyor device, the length of the inclined conveyance section 56 is set according to the loading height of bulk materials, and when the loading height of bulk materials is high, the total length of the trolley 52 becomes longer.
Accordingly, it is necessary to lengthen the travel range of the truck 52.

However, it is not possible to transport bulk materials from the tail roller 54 to the portion corresponding to the length of the inclined conveyance section 56, and therefore, a dead space is inevitably generated, and this dead space is caused by the loading height of the bulk materials. There is a problem that the size increases accordingly. Further, there is a problem in that the installation floor area of the hair conditioning apparatus becomes large depending on the loading height of bulk materials, and the cost of the apparatus increases.

When storing coal, etc., it is sometimes stored in piles in an indoor yard to prevent dust from scattering. Furthermore, when storing grains, etc., it is common to store them in piles in an indoor yard. In this way, when bulk materials are stored in piles in an indoor yard, it is preferable to effectively utilize the height, floor space, etc. of the building. Furthermore, when carrying out cargo handling work such as grains, it is not preferable to expose the entire container device to the open air. There is a problem in that it is necessary to increase the floor area of the building, and the floor area corresponding to the dead space cannot be effectively used as a storage yard.
