Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a segment conveying device, a feeding device, and an assembling device, which are auxiliary facilities of a shield machine.

[0002]

2. Description of the Related Art A method of sequentially assembling segments into holes drilled by a shield excavator and constructing a tunnel is already well known, but an automatic segment assembling system for this purpose is provided with an auxiliary equipment of the shield excavator. It is commonly known as

[0003] This system is mainly composed of three devices, a transport device, a supply device and an assembly device. First, the transfer device transfers a predetermined number of segments from the starting shaft to the assembly position. Then, at the assembling position, the supply device delivers the transported segment to the assembling device. Further, the assembling apparatus moves the received segment to the installation position of the existing tunnel and positions it. Thereafter, automatic assembling by an assembling apparatus or assembling by manual work are performed.

Conventionally, a carrier is generally used as a carrier, and segments are carried on the carrier in a laterally stacked state. In addition, a hoist is generally used as the supply device, and the segment is supplied from the position of the bogie to the position of the assembling device while the segments remain horizontal. Further, an assembling apparatus generally includes a gripper for gripping a supplied segment and a rail for moving the gripper along the inner periphery of the tunnel.

[0005]

However, such a conventional apparatus has a drawback that it is not suitable for constructing a tunnel having a small cross section.

That is, in the transport device, since the segments are transported in a horizontal state, a sufficient passage space or the like cannot be secured. Also, with respect to the supply device, if the height dimension is small, a hoist rail or the like cannot be provided. Furthermore, it becomes impossible for the assembly device to rotate the segment along the inner periphery of the tunnel.

Therefore, an apparatus effective for constructing a tunnel having such a small cross section is desired. On the other hand, it is necessary to pay sufficient attention to obtain an assembly efficiency equivalent to that of the related art.

[0008]

According to the present invention, there is provided a transporting apparatus for a segment, which comprises a transporting means which travels in the longitudinal direction of the tunnel while supporting the segment in an upright state along the longitudinal direction of the tunnel. Are provided in multiple rows in the tunnel width direction.

According to this, the segments are transported in a double row in a state of being erected along the longitudinal direction of the tunnel. Therefore, the space for transporting the segments in the tunnel width direction can be reduced, and a sufficient passage space or the like can be secured. Further, since a plurality of segments can be simultaneously transferred to the assembly position, sufficient transfer efficiency can be obtained.

Next, a segment supply device according to the present invention is provided with a gripping means for gripping a conveyed segment in an upright state along the longitudinal direction of the tunnel, and an axis extending along the tunnel height direction. And a rotating means for rotating the segment so as to stand the segment along the tunnel width direction.

[0011] According to this, the rear segment conveyed by the above-mentioned conveying device is turned forward while turning, and can be smoothly supplied to the front assembling device.

Next, a segment assembling apparatus according to the present invention comprises a gripping means for gripping a supplied segment in an upright state along the tunnel width direction, and the gripping means around an axis along the tunnel width direction. Turning means for turning the segment to turn the segment sideways.

According to this, the segment supplied from the supply device can be turned upside down or down at the rear, and changed to a posture suitable for the upper and lower assembling positions. Thereafter, if the gripper is moved in parallel to the assembling position, the segment can be positioned at a desired assembling position.

In FIGS. 1 and 2, reference numeral 64 denotes a shield jack, and reference numeral 65 denotes a discharge pipe and various cables (hereinafter referred to as a discharge pipe and the like).

Next, the operation of this embodiment will be described.

The transport, supply and assembly of the segments by the above-described apparatus are performed as follows. First, with respect to the transportation, three carriages 11 are self-propelled and transported in a state where six segments 2 are set up. Also, at this time, the two center pillars 5
They are transported in a horizontal position. When the segment 2 and the center pillar 5 are assembled and the trolley 11 becomes empty, the trolley 11 returns to the shaft and returns to the segment 2 for one ring.
And the center pillar 5. In this way, the cart 11
Reciprocates between the assembly position and the shaft every time one ring is assembled. The rail 10 for one ring is added as the assembly position advances.

Here, in particular, in the transfer device 6,
The segment 2 is transported in a state of being erected along the longitudinal direction of the tunnel. Accordingly, the space for transporting the segments 2 in the tunnel width direction can be reduced, and a sufficient passage space and a space for placing the discharge pipe 65 can be secured. In particular, the middle pillar 5 stands in the tunnel 3, and the segment 2 interferes with the middle pillar 5, so that the conventional horizontal cart cannot be used. In the transport device 6, since the segments 2 are placed upright on the cart 11, transport can be performed even in a limited space partitioned by the center pillar 5. In this embodiment, the transport area is the central area, but the transport area is arbitrary, and the left and right areas may be used.

Further, in the transport device 6, the segments 2 are transferred in a double row, here, in two rows. Therefore, a plurality of segments 2 can be simultaneously transferred to the assembly position,
Sufficient transport efficiency can be obtained.

As described above, in the above configuration, the carriage 11 as the transfer means simultaneously transports the segments 2 in two rows, and the carriages 11 are common to the two rows. However, it is of course also possible to provide the carts individually for two or more rows.

Next, the transfer of the segment 2 from the transport device 6 to the supply device 9 is performed by driving the slat conveyor 12 of the cart 11 and moving the segment 2 forward with the cart 11 fixed. Do. At this time, as shown in FIG. 1, the slat conveyor 12 of the carriage 11 and
The position of the feeding device 9 with the slat conveyor 24 along the tunnel width direction is adjusted. The operating speeds of the slat conveyors 12 and 24 are also adjusted. In this way, the segment 2 on the carriage 11 is smoothly transferred onto the slat conveyor 24 of the supply device 9.

FIG. 1 shows a state in which the right segment 2 is delivered when viewed from behind the tunnel. When the left segment 2 is delivered, the base 19 of the supply device 9 is moved to the left. Similar positioning of the slat conveyor 24 is performed. The slat conveyor 12 of the cart 11 is driven simultaneously for all the carts, one side at a time.
Is achieved simultaneously.

As described above, since the slat conveyor 12 as the conveyor means is provided on the carriage 11, the segments 2 can be transferred while the carriage 11 is stopped, so that the transfer efficiency and the degree of freedom of transfer can be improved. Further, since the slat conveyor 24 as a conveyor means is provided in the supply device 9, the transfer of the segment 2 from the transport device 6 to the supply device 9 can be smoothly performed.

Here, as the conveyor means, various types such as a belt conveyor having an endless circulating conveyance surface, an apron conveyor, a caterpillar conveyor and the like can be adopted. 2 can be reduced, and the damage can be prevented. That is, since the slat conveyor 12 has a flat receiving surface for receiving the slats 15 made of flat metal, the slat conveyor 12 has no line contact unlike other conveyors. Therefore, the segment 2 can always have a uniform surface contact, and the segment 2 can be prevented from being damaged.

There are also the following features. FIG. 16 shows a partial cross section of the slat conveyor 12 of the bogie 11,
The slat 15 is provided with a groove 66 in which the seal 67 of the segment 2 is accommodated. This can prevent the seal 67 from being crushed by the load of the segment 2 and protect the seal 67 during transportation. In particular, in the conventional horizontal stacking method, no load is applied to the seal 67, but in the case of vertical stacking as in the present apparatus, the load is applied to the seal 67, so this configuration is very advantageous.
Although not shown, the slat conveyor 2 of the supply device 9 is not shown.
4 has a similar configuration.

Next, as for the supply of the segment 2, as shown in FIG. 4, the segment 2 on the carriage 11 is transported forward to a position indicated by the imaginary line 2c.
7, the pressing member 35 and the slat conveyor 24
And between them. After that, the projecting jack 28 is extended and the projecting jack 28 is stretched to prevent it from falling down in advance. Further, the motor 25 is operated to rotate the swing arm member 22 forward by 90 ° to position the segment 2 at the position indicated by the imaginary line 2d. This position is a delivery position to the assembling device 8.

Thus, the segments 2 transferred from the transport device 6 can be smoothly supplied to the assembling device 8. In particular, since the base ends of the support shaft 21 and the swing arm member 22 are made to protrude outside the middle pillar 5, the segment 2 can be turned even in a narrow place sandwiched by the middle pillars 5, and supply is possible. Become. Note that the above example is the case of supplying the right segment 2 when viewed from the rear, but in the case of the left, after aligning the base 19 and gripping the segment 2, the base 19 is moved to the position shown in the figure.
