2. Description of the Related Art A belt conveyor as a device for transporting earth and sand requires that transportation be performed quietly and that a road be necessary when using a vehicle such as a truck. However, there are advantages that a small cross-sectional area can be used, dust pollution during transportation can be avoided, and labor costs can be reduced and efficiency can be expected.

[0003] By connecting a plurality of the belt conveyors, it is possible to transport even a long distance. However, as shown in FIG. 3, the connection of the belt conveyors is performed by connecting the belt conveyor 1 to its end portions 1a and 1b. This is done by cascading each other so that they overlap each other.

In order to maintain the upper and lower overlapping relation of the belt conveyor 1, one end of one belt conveyor 1 is supported by a table 2 arranged on the floor surface and the whole is inclined so as to rise.
The end of the belt conveyor 1 following this is positioned so as to sink below the end of one of the belt conveyors 1 supported by this platform 2.

[0005] In this manner, the belt conveyor 1
Is transported from the lower end that is not supported by the upper end to the higher end that is supported by the platform 2, and then falls from the end and is placed on the belt of the next belt conveyor 1, and is similarly transported repeatedly. To go.

[0006]

However, in tunnel construction, since the work site progresses along with excavation of the face, it is necessary to change the equipment. In the case of the belt conveyor 1, the belt conveyor 1 is extended one by one with the advance of the face, so as to correspond to the movement of the work place. When the base 2 is connected to the belt conveyor 1, the base 2 is moved separately with the base 2 separately, and when the base 2 is separated from the base 2, These will be moved separately.

Further, when removing the equipment after the work is completed, it is necessary to disassemble the belt conveyor 1 one by one and carry it out of the mine.

As described above, in the conventional conveyor using the belt conveyor 1, it takes a great deal of time to rearrange the equipment in accordance with the movement of the work place and to dismantle the equipment after the work is completed.

It is an object of the present invention to provide a transportation device for soil and the like which can solve the disadvantages of the above-mentioned conventional example, greatly simplify the replacement and dismantling of equipment, and can streamline construction and save labor. is there.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a conveying apparatus for arranging a belt conveyor such that the belt conveyors are vertically arranged such that the ends thereof are vertically stacked.
The belt conveyor has a frame with pipes on the left and right sides, and the ends of the belt conveyor are vertically overlapped by fixing the frame with a clamp hardware on a simple frame body in which the pipes are framed in a pyramid shape on a trolley. In this way, the gist is to support with the simple frame.

[0011]

According to the present invention, the fixing of the belt conveyor and the frame on the carriage is performed by the clamp hardware, so that the connecting work between the two is simplified.

[0012] The belt conveyor located at the top is
While the frame located at the end is fastened and fixed to the frame on the trolley with four pipes, front and rear and right and left, which are its constituent members, with clamp hardware, the belt conveyor fixed below this is fixed. In order to minimize the overlap between the upper and lower parts, the frame located at the end of the belt conveyor is fastened to the frame on the trolley with only two right and left pipes located at the front or rear of the constituent pipes using clamp hardware. However, even if the load of the upper and lower belt conveyors is fixed so as to be deviated with respect to the frame, the frame does not tilt because the frame is a pyramid.

[0013] Then, the connection of the belt conveyors is performed via a simple frame body in which pipes are framed in a pyramid shape on a carriage so that the belt conveyors are vertically connected to each other. It can be accompanied to move to the work location.

[0014]
