Description of the Related Art As is known, an erector ring gutter which is supported on a skin plate of a shield machine so as to be rotatable about a shaft thereof by a power source such as a hydraulic motor is provided therein. A required number of hydraulic hoses and the like are connected between the erector main body and the hydraulic tank in order to operate the erector main body and hold the segment to be rotatable to a desired position. . In this case, since the above-mentioned erector ring gutter is used by rotating, a long hydraulic hose with a considerable margin is provided, but conventionally such a long hydraulic hose or power cable is used. In such a case, it is possible to follow the rotation of the erector body by leaving it exposed in the skin plate, or by bundling hydraulic hoses and pulling them with springs. Hose or the like is entangled with the erector body, causing a cutting accident or reducing workability in the skin plate.

[0003] Separately, hydraulic hoses and power cables are separately required.
Wound on each hose reel, cable reel,
It is also practiced to automatically pull out or wind up this, but since the hose reel or cable reel itself occupies a considerable space, various inspections and adjustments inside the shield machine, And it is difficult to perform various maintenance work.

[0004] Therefore, in order to solve the above-mentioned various defects, one disclosed in FIGS. 4 to 8 has already been disclosed as Japanese Utility Model Publication No. 2-48558. Here, in order to make it easier to understand the contents of the present invention, known examples according to the publication will be described first as follows. That is, according to the conventional example, the problem in the conventional example is to be solved, and the additional portion provided in the erector ring gutter and the additional portion provided in the vicinity thereof are provided without exposing the hydraulic hose or the like as it is. By properly sandwiching the hydraulic hose in a folded state between the additional member provided on the known shield machine ring gutter and the above-mentioned various problems, the above-mentioned difficulties can be solved, and the hydraulic hose can be used sufficiently and sufficiently. Short things are enough.

[0005] That is, as can be understood from FIG. 4 and FIG. 5, 1 is a skin plate of the shield machine S,
Reference numeral 2 denotes a segment elector device, and its erector ring gutter 3 is rotatably supported about the axis of the skin plate 1 by a plurality of receiving rollers 4 supported in the skin plate 1. A power source 6 such as a hydraulic motor is fixedly mounted on the shield machine ring gutter 5 fixed to the interior as a center, and by operating the power source 6, a rotating gear 8 provided on a rotating shaft 7 and an outer periphery of the erector ring gutter 3 The erector ring gutter 3 can be driven by a desired rotation angle such as 200 degrees due to the meshing configuration with the receiving gear 9 engraved on the eccentric ring. In the figure, reference numeral 10 denotes an erector body fixedly mounted on the erector ring gutter 3, which operates so as to be able to grip and rotate a segment (not shown) by hydraulic pressure, and 11 designates the erector body 10 The figure shows a plurality of hydraulic connection ports provided in.

[0006] Here, the shield ring gutter 5 is located on the side of the erector ring gutter 3, and as shown in FIG. And a horizontal ring plate portion 5b fixed laterally so as to be orthogonal, and an L-shaped shield machine hose from the left side of the horizontal ring plate portion 5b, that is, from the opposite side of the erector ring gutter 3. Case 12
Is formed on the inner peripheral side. Therefore, the above-mentioned shield machine hose case 12 has an abutting vertical plate portion 12a which is orthogonally erected from the horizontal ring plate portion 5b, and an inner circumferential lateral portion which extends orthogonally from the tip to the erector ring gutter 3 side. And a plate portion 12b.

On the other hand, the erector ring gutter 3 is provided with an erector hose case 13 which, in the illustrated example, is provided so as to protrude orthogonally and horizontally from the erector ring gutter 3 and interposes an insertion gap 14 with the inner peripheral horizontal plate portion 12b. An inner peripheral large horizontal plate portion 13a in an abutted state, and an outer small width horizontal plate portion 13b protruding from the erector ring gutter 3 in a direction orthogonal to the above-mentioned erector ring girder 3, the tip of the plate portion 13b and the horizontal mounting ring The tip of the plate portion 5b is in a butted state via the small gap 15. In this way,
The above-mentioned horizontal ring plate portion 5b and the shield machine hose case 1
2, the storage space A is enclosed by the fixed storage case A1 formed by the erector ring gutter 3 and the erector hose case 13 and the rotation storage case A2 formed by the erector hose case 13.

Further, a required number of hydraulic hoses 17 are connected between the hydraulic connection port 11 of the erector body 10 and a hydraulic tank 16 disposed at an appropriate position, as is well known, which is disclosed in FIG. After introducing a plurality of hydraulic hoses 17 connected to the hydraulic connection port 11 into the storage space A, the hydraulic hoses 17 are turned back at the folded portion B, and the ends of the hydraulic hoses 17 are moved outward from the insertion gaps 14. And then connected to a supply connection port 18 provided at a fixed location of the fixed storage case A1.
And a connection hose section 17 '.

At this time, the hydraulic hose 17 in the storage space A is used.
As clearly shown in FIG. 5, the hose introduction portion 17a and the hose lead-out portion 17b located on the left and right sides of the folded portion B are sandwiched between the erector ring gutter 3 and the contact vertical plate portion 12a, respectively. ing. That is, the hydraulic hose 17 is determined to have a minimum bending radius. If the hydraulic hose 17 is bent at the turn-back portion B within this range, the hose introduction portion 17a and the hose lead-out portion 17 as shown in FIG.

Therefore, in the above configuration, if the power source 6 is operated to rotate the erector ring gutter 3, the hydraulic hose 17 stored in the storage space A is changed depending on the rotation direction.
Means that the position of the folded portion B advances in one direction or retreats conversely, so that the hydraulic hose 17 can always cope with the assembling work of the segment while the sandwiched state in the storage space A is maintained. can do.

[0010] Here, the hydraulic hose disclosed in FIG. 7 is not provided in the storage space A formed on the outer peripheral side but on the outer peripheral side instead of the inner peripheral side of the horizontal mounting ring plate portion 5b, contrary to the case of FIG. 17 are accommodated, and the one shown in FIG. 6 described above is suitable for the case where the skin plate 1 has a small or medium diameter, whereas the case of FIG. 7 is adapted for a large diameter shield machine. In the same figure, the shield machine hose case 12 is formed by an outer peripheral horizontal plate portion 12b 'which is provided orthogonally to the vertical mounting ring portion 5a, and the erector hose case 13 has an outer peripheral large horizontal plate 13a', An insertion gap 14 is formed by an inner peripheral narrow horizontal plate 13b 'that is provided orthogonally from the erector hose case 13, and an insertion gap 14 is formed between the outer peripheral large horizontal plate 13a' and the outer peripheral horizontal plate 12b '. A small gap 15 is formed between the ring plate portion 5b and the inner peripheral small width horizontal plate 13b '.

Therefore, when using the conventional hydraulic hose storage device having the above configuration, the hydraulic hose 17 is
There is no fear that the hydraulic hose 17 is stored with the folded portion B so that the hydraulic hose 17 is stored with the folded back portion B for the rotation of the erector ring gutter 3. The erector body 10 is moved without following, and is stored in a state where friction does not occur.
Considering the screwing range (200 degrees), the length of the hydraulic hose 17 can be made shorter than the entire circumference, and a wide inner space can be released in the skin plate 1, so that the inside of the shield machine is Inspection, adjustment, and maintenance can be easily performed.

The above-mentioned conventional example has the above-mentioned advantages and can improve the above-mentioned conventional example. However, in recent years, the multifunctionality of the segment erector device has been required, and accordingly, It is considered that the required number of supply flexible wires such as hydraulic hoses and power cables is required. By the way, according to the above conventional example, as shown in FIG. 6, two hydraulic hoses 17 are folded back in one storage space A in a stacked state and stored in the storage space A. In addition, the two hydraulic hoses 17 may be entangled because they are in a stacked state, and one hydraulic hose 17 is fitted inside the two stacked ones as shown in FIG. Even if three are stored, the danger of entanglement is increased and only one hydraulic hose 17 can be increased.

Further, according to the conventional example, as can be understood from FIG. 5, the hose introduction portion 17ba of the hydraulic hose 17 is bent back from the folded portion B on the right side a of the drawing, and further on the left side of the drawing. However, since only the hose lead-out portion 17b is housed, the hydraulic hose 17
Of the storage space A where the hydraulic hose 17 is not stored is short, so that the storage space A cannot be used for storing the hydraulic hose 17.
