DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a tube carrier.
In particular, the present invention relates to a tube carrier suitable for carrying a reinforced plastic tube or the like into a primary lining.

[0002]

2. Description of the Related Art When a fiber reinforced plastic pipe or the like for secondary lining is carried into a tunnel or the like as a primary lining,
Conventionally, as shown in FIG. 4, a rail 2 or the like as rail equipment is laid on the bottom of the underground shield primary lining 1, and a transport trolley 3 that can travel on the rail 2 is provided. The transport trolley 3 travels by being connected to a battery-type locomotive or the like (not shown). Then, the tube 4 for secondary lining is mounted horizontally on the carrier 3 for carrying.

[0003] However, when the pipe 4 is mounted on the transport cart 3 and transported, the rail 2 and the transport cart 3 are provided between the transported pipe 4 and the inner surface of the segment of the shield primary lining 1. A gap S is required. For this reason, the pipe 4 having a diameter in which the gap S cannot be secured cannot be transported. In this case, the size of the pipe 4 for the secondary lining must be reduced.

In order to solve such a problem, conventionally, as shown in FIG. 5, a position in front of a horizontal pipe 4 to be transported inside the primary lining 1 and a position behind the horizontal pipe 4. In this position, trucks 5 and 6 that can travel on the rail 2 at the bottom of the primary lining 1 are arranged, and these carts 5 and 6 are provided with up-and-down direction stays 7 and 7, respectively. A transport cart 9 having a horizontal pipe support rod 8 longer than the pipe 4 is used between upper ends of the pipes 7. The transport cart 9 can transport the pipe 4 by supporting the inner surface of the top of the pipe 4 with the pipe support rod 8.

[0005] With such a configuration, the carts 5 and 6 are located forward and rearward of the tube 4 as described above, and are not located below the tube 4, and are therefore larger than those shown in FIG. It is possible to transport tubes of diameter.

However, since the pipe support rod 8 is provided between the two carts 5 and 6, the distance between the axles becomes long, and it may be difficult to cope with a curved pipe. When the pipe 4 transported by the transport cart 9 is joined to an existing pipe, as shown in FIG.
Although the pipe 4 supported by the above is transported to just before the existing pipe 10, the bogie 5 is located between the pipe 4 and the existing pipe 10, so that the joining cannot be performed as it is. Therefore, as shown in the drawing, a centering device 11 is previously arranged inside the existing pipe 10, and a pipe support 12 protruding in the horizontal direction of the centering device 11 is connected to the existing pipe 10 by a transport cart 9. As they approach
Insert inside this tube 4. And, this pipe support 12
The pipe 4 supports the inner surface of the top portion of the pipe 4 near the existing pipe 10, and removes the bogie 5 in this state, and
The pipe 4 is centered with respect to the existing pipe 10 by adjusting the position of the pipe 2 up, down, left and right, and then the ends of the pipe 4 are inserted into the existing pipe 10 to join the pipes 4 and 10 together.

However, in such a case, the carrier 9
In addition to the above, there is a problem that the centering device 11 is separately required and a step of removing the carriage 5 from the transport carriage 9 occurs.

[0008]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems and to enable a secondary lining pipe having a diameter as large as possible to be laid in a primary lining. Even if there is a bend, the pipe can be transported without problems,
Another object of the present invention is to make it possible to easily carry a pipe and join it to an existing pipe without requiring any special device other than the transport trolley and without requiring an extra step.

[0009]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention has a pipe supporting rod inserted into a pipe and supporting the pipe in a horizontal direction, and the pipe supporting rod is cantilevered on a traveling carriage. It is made to be attached in a state.

With such a configuration, the cantilever is inserted into the inside of the pipe from behind the pipe by inserting the cantilever type pipe support rod, and the bogie is run while supporting the pipe in the horizontal direction. There is no bogie on the lower side, so the pipe with the largest diameter can be laid in the primary lining, and the pipe is only supported in a cantilever manner by the pipe support rod, so the device does not become long,
Therefore, even when the primary lining has a bend, the pipe can be transported without any problem. In addition, since this pipe is only supported in a cantilever manner from the rear of the pipe in this way, a special device other than the carrier is inserted by inserting the front end of the supported pipe into the end of the existing pipe. It is possible to easily carry the pipe and join it to the existing pipe without requiring any additional steps and without any extra steps.

According to the present invention, the pipe support rod can be configured to be pivotable about a vertical axis. Such a configuration allows the pipe supported by the pipe support rod to be swiveled in the horizontal direction, and is therefore particularly advantageous when the primary lining has a bend. Further, there is an advantage that the pipe can be centered in the horizontal direction with respect to the existing pipe, and it is not necessary to use a separate centering device.

Further, according to the present invention, the pipe support rod can be configured to be able to move up and down. With such a configuration, it is possible to center the pipe vertically with respect to the existing pipe, and there is an advantage that it is not necessary to use a separate centering device.

[0013]

FIG. 1 shows a tube carrier according to an embodiment of the present invention. The tube transport vehicle 21 has a vehicle 23 with wheels 22 that can run on rails laid inside the primary lining, and a vertical column 24 is provided on the vehicle 23. The support column 24 is configured to be rotatable around a vertical axis by a hydraulic device or the like.

A horizontal pipe support rod 25 is supported on the column 24 in a cantilevered state. That is, the pipe support rod 25
Is configured so that one end thereof is supported by the column 24 and extends from the column 24 in the horizontal direction, and the other end, that is, the tip 26 is a free end that is not supported at all. The pipe support rod 25 is configured to be able to move up and down along the column 24 by a hydraulic device or the like. The pipe support rod 25 includes a pair of rod bodies 27, 2
7 are arranged side by side at an appropriate distance in the horizontal direction.

In such a configuration, when the pipe 4 for secondary lining is transported inside the primary lining 1 as shown in FIG. 2, the pipe 4 is transported outside the primary lining 1. The tube support rod 25 of the tube carrier 21 is inserted into the inside of the tube 4 from the rear in the desired direction. Then, by raising the pipe support rod 25 or lowering the pipe 4 suspended by another means, the pipe support rod 25 is applied to the inner surface of the top of the pipe 4 and the pipe 4 is horizontally moved. To support. At this time, the pipe support rod 25 has a configuration in which the pair of rod bodies 27, 27 are arranged side by side at an appropriate distance in the horizontal direction, so that the pipe 4 can be supported in a stable state.

Next, the pipe 4 is positioned vertically with respect to the primary lining 1 by raising and lowering the pipe support rod 25,
The pipe 4 is positioned in the horizontal direction with respect to the primary lining 1 by the rotation of the pipe support rod 25 based on the rotation of the column 24. In this state, the carriage 4 is caused to travel along the rail 2, whereby the pipe 4 is inserted into the primary lining 1 and transported.

At this time, the pipe 4 is supported by the cantilever type pipe support rod 25, and there is no bogie below the pipe 4; 4 can be carried in and laid. Further, since the pipe 4 is only supported in a cantilever manner by the pipe support rod 25 extending horizontally from the carriage 21, the apparatus is not lengthened, and therefore, even if the primary lining 1 has a bend, there is no problem. 4 can be carried. By rotating the pipe support rod 25 in the horizontal direction by the rotation of the column 24, the pipe 4 can be transported more easily when the primary lining 1 has a bend.

As shown in FIG.
Is transported to just before the existing pipe 10, the pipe 4 is centered with respect to the existing pipe 10 by raising and lowering the pipe support rod 25 and turning the pipe support rod 25 based on the rotation of the column 24. Then, by moving the carriage 21 forward in this centered state, the pipe 4 is joined to the existing pipe 10, and a secondary lining is constructed. At this time, the cart 21 supports the pipe 4 in a cantilever state, and no other cart or the like is arranged between the pipe 4 and the existing pipe 10. Immediately after transport to the vicinity of 10, the centering of the tube 4 and the joining of the two 10, 4 can be carried out, so that the work can be carried out easily. Further, the pipe 4 can be centered with respect to the existing pipe 10 by turning and raising and lowering the pipe support rod 25, and there is an advantage that a special device for this centering is not required.

[0019]

As described above, according to the present invention, there is provided a pipe support rod which is inserted into a pipe and supports the pipe in a horizontal direction.
Since this pipe support rod was attached to the traveling trolley in a cantilever state, this cantilever type pipe support rod was inserted into the inside of the pipe from the rear of the pipe to support the pipe horizontally. However, by running the bogie, there is no bogie below the pipe, so the pipe can be laid as large as possible in the primary lining, and the pipe can only be supported in a cantilever manner by the pipe support rod. Therefore, even if the device is not long and the primary lining has a bend, the tube can be transported without any problem. In addition, since this pipe is only supported in a cantilever manner from the rear of the pipe in this way, a special device other than the carrier is inserted by inserting the front end of the supported pipe into the end of the existing pipe. The transfer of the pipe and the joining with the existing pipe can be easily performed without the need for any additional steps and without any extra steps.

Further, according to the present invention, since the pipe supporting rod is configured to be able to turn around the vertical axis, the pipe supported by the pipe supporting rod can be turned in the horizontal direction. It is particularly advantageous when the lining has a bend. Further, there is an advantage that the pipe can be centered in the horizontal direction with respect to the existing pipe, and it is not necessary to use a separate centering device.

Further, according to the present invention, since the pipe supporting rod is configured to be able to move up and down, the pipe can be centered vertically with respect to the existing pipe, and there is an advantage that it is not necessary to use a separate centering device. is there.
