Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scrap discharge device for discharging a scrap generated by excavation or blasting due to tunnel construction to the outside of the tunnel, and in particular, it falls in a predetermined direction without installing a tipping stand on the ground. The present invention relates to a slip discharge device that discharges the slip stored inside.

[0002]

2. Description of the Related Art In constructing a tunnel, a sludge composed of earth and sand or rocks produced by excavation or blasting is discharged to the outside of the tunnel. For example, as shown in FIG. 4, the discharge of the slip in the vertical shaft of the shield construction method may be performed using a bottomed slip accommodating box 2 having an open top. The slip container box 2 has horizontal pins 2a protruding from the upper portions of both sides thereof, and in the tunnel, it is placed by engaging the pins 2a on a trolley that travels on rails. And the wire 3 suspended at both ends of the horizontal jig 3
By engaging a with the pin 2a at the lower part of the standing pile and pulling up the horizontal jig 3 with a crane (not shown), it is separated from the truck and pulled up to the ground. In addition, on the lower portions of both sides of the slip accommodating box 2, a falling pin 2b is horizontally projected at a position eccentric to the pin 2a. Such a slip accommodating box 2 is hung down by a crane in a vertical shaft and laterally moved by a truck in a tunnel so that the slip 4 is accommodated inside. Next, when the sludge 4 reaches a predetermined amount, the sled storage box 2 is transported to the lower part of the vertical pile by the truck, and is lifted to the ground by the crane.

To release the sludge 4 from the sludge storage box 2,
A tipping stand 6 as shown in the figure is used. Falling platform 6
Comprises a pair of H-shaped steels standing upright at predetermined positions on the ground so as to have a space corresponding to the length dimension of the shear-containing box 2. A receiving portion 6a is formed to receive the second overturning pin 2b.

The slide accommodating box 2 pulled up to the ground is lowered by the crane while aligning the two pins 2b with the receiving portions 6a of the inversion pedestal 6 at the same time. When the two pins 2b are engaged with the receiving portions 6a of the overturning platform 6 and the slide containing box 2 is further lowered, the slide containing box 2 falls down around the pins 2b, and the slide 4 stored inside the box is removed. Is released.

As described above, the device for discharging the slips 4 by inclining the slip storage box 2 discharges the slips by opening and closing the bottom opening of the storage box 2 by hydraulic pressure to remove the dirt. There is an advantage that there is no problem that a gap is created by the pinching and as a result, there is no problem that the inside of the box is misaligned and sewage leaks from this gap.

[0006]

By the way, when the slip container 2 is toppled, the crane container 2 is lowered by the crane, and the two pins 2b and the receiving portion 6a are aligned at the same time. Not only does it have to be highly skilled in the work, it is not possible to eject the slips quickly, and if any disengagement occurs, it is necessary to raise the storage box and then lower it again. The discharge of the pickpocket was delayed. On the other hand, as shown in FIG.
By projecting one flange of the H-shaped steel constituting the above upward, the pin 2b is abutted against the inner surface of the flange, and if the housing box 2 is lowered in this state, the pin 2b is dropped into the receiving portion 6a. Therefore, the alignment can be performed easily and quickly. However, there is a problem that large noise and vibration occur when the pin 2b of the slip accommodating box 2 is abutted against the flange of the overturning base 6 and when the pin 2b is dropped into the receiving portion 6a in this state.

Further, since the discharge place of the slip is specified by the installation position of the inversion mount 6, in order to discharge a larger amount of slip by one inversion mount, it is necessary to level the discharged slip. The work is complicated. On the other hand, it is conceivable to raise the tipping rack to increase the allowable discharge amount, but at the beginning of discharge, the height of the drop discharged from the storage box is high, and there is a problem that impact noise and vibration occur. .

Furthermore, the installation work of the falling pedestal 6 and the removal work thereof are complicated, and in particular, when a large number of low tumbling pedestals are installed in order to suppress the impact noise due to the drop height of the slip, Even more so.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a misalignment ejecting device which can easily and quickly eject misalignment without causing a large amount of noise. .

[0010]

In order to achieve the above-mentioned object, a slip discharge device according to the present invention is provided with a slide storage box, which is hung in a horizontal state by a crane via a jig and has an open top, in a predetermined direction. A slip discharge device for discharging the slip accommodated inside by tipping over, wherein a linear body that can be reeled out by a winding device provided in the jig is provided on one side of the slip storage box. It is characterized in that the tip end of the linear body is connected to the outer side portion of the slip accommodating box while being routed along.

[0011]

According to the slip accommodating box of the present invention having the above structure,
In a state in which the sled storage box is suspended in a horizontal state, the sled storage box is hung by a crane on a vertical shaft or the like, and the sludge is stored inside the tunnel in the tunnel. After a predetermined amount of sludge is stored in the sled storage box, the storage box is lifted by the crane and moved horizontally, and the linear body is wound by the winding device at any position, and the sled storage box falls. The slip inside the box is released. After the misalignment is discharged, if the linear body is unwound by the winding device, the misalignment box returns to the horizontal state by its own weight.

[0012]
