DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shielded excavated conveyed object transfer device for conveying conveyed objects in underground shield excavation between the ground and a pit.
In the present invention, the conveyed object means a segment of a tunnel, other materials, sub-materials, equipment, earth and sand generated along with the excavation, which are required along with the excavation of the shield.

[0002]

2. Description of the Related Art Conventionally, in shield excavation in the ground, a conveyed object for shield excavation for conveying conveyed objects such as a segment forming an excavation shaft and earth and sand generated when excavating between the ground and the excavation shaft. As the transfer device, for example, by using a normal crane installed on the ground, the transferred object is lifted and lowered while hanging between the ground and the down shaft that leads to the shaft, and the transferred object or the excavated object that is lowered below the shaft. A conveyed object such as earth and sand carried out to the entrance of the pit is transported between the position directly below the crane and the excavation entrance by a so-called traversal trolley provided under the shaft, which can be transported in the horizontal direction.

On the other hand, it is known that a truck having a function of automatically running segments from the ground is lowered down to a down shaft by a segment lift while being loaded on a bogie, and further, the bogie is automatically run from the down shaft to a face portion and conveyed. Have been.

[0004]

However, a transfer apparatus and a transfer method for transferring a transferred object from the ground down to the shaft or from the shaft down to the ground by using the above-mentioned crane require skill in the hanging operation. In addition, it was necessary for workers to take measures to ensure safety. In addition, it takes a long time to carry, and the number of personnel required for the work is large, which is inefficient.

[0005] On the other hand, a transfer apparatus or a transfer method for loading and transferring segments onto a carriage capable of automatically traveling has a limitation in the traveling direction of the carriage, and the transfer direction cannot be changed to a substantially right angle in a narrow space. There is no degree of freedom in selecting a transfer place, and it is difficult to temporarily evacuate, making work inefficient, and a large number of bogies must be equipped with a drive device that enables automatic travel, resulting in manufacturing costs. However, there is a problem that the weight increases as the weight increases.

[0006] Further, the above-described transport device or transport method using a trolley requires a vertical mast or the like integrally formed with a guide rail in order to support the load of the trolley on which the segments are loaded, resulting in an increase in cost. there were.

SUMMARY OF THE INVENTION It is an object of the present invention to convey a conveyed object in an underground shield excavation efficiently between the ground and an excavation pit, thereby shortening the construction period and reducing the construction cost. It is to provide a device.

[0008]
