Hereinafter, the present invention will be described through embodiments of the present invention. In the following description, an embodiment of the present invention will be described using an example of a holding device that holds a movable tubular body composed of seven tubular bodies connected by five swivel joints. However, the holding device according to the present invention is not limited to the movable tubular body, and any movable member such as a flexible hose or a movable member in which a plurality of members are deformably connected by a connecting member is the same as the movable tubular body. can be held.

FIG. 1 is a diagram showing a holding device 10 according to this embodiment. FIG. 1(a) is a front view, and FIG. 1(b) is a right side view. The holding device 10 according to the present embodiment is used, for example, when attaching a movable tubular body to a descaling facility (hereinafter referred to as "equipment") used in a steel plate manufacturing process.

The holding device 10 has a beam member 12 and five clamping members (first clamping member 14, second clamping member 16, third clamping member 18, fourth clamping member 20 and fifth clamping member 22). The beam member 12 has a first body portion 24 , a second body portion 26 , a first fixing member 28 and a second fixing member 30 . The first main body portion 24 and the second main body portion 26 are, for example, H-section steel having the same cross-sectional shape, and the length thereof is appropriately determined according to the shape when the movable pipe body 40 is attached to the equipment. The first body portion 24 and the second body portion 26 are fixed from both sides by a first fixing member 28 and a second fixing member 30 . The first body portion 24 and the second body portion 26 are fixed to the first fixing member 28 and the second fixing member 30, respectively, by bolts (not shown), for example.

The first to fifth clamp members 14 to 22 are members having circular holes or U-shaped holes, and are fixed to the beam member 12 respectively. The first to fifth clamp members 14 to 22 are fixed to the beam member 12 by bolts (not shown), for example. If it is difficult to directly fix the clamp member to the beam member 12, it may be fixed to the second clamp member 16 like the first clamp member 14, or fixed to the beam member 12 like the fifth clamp member 22. It may be indirectly fixed to the beam member 12 via a fixed plate 32 .

The first clamp member 14 to fifth clamp member 22 hold the tubular body of the movable tubular body. Since the first clamp member 14 to the fifth clamp member 22 are fixed directly or indirectly to the beam member 12, respectively, the tubular body is held by the clamp members, so that the tubular body of the movable tubular body can be moved. The position is fixed and positioned with respect to the beam member 12 . In the present embodiment, the first clamping member 14 and the fourth clamping member 20 are examples of end fixing members that hold the ends of the movable tube, and the second clamping member 16, the third clamping member 18 and The fifth clamp member 22 is an example of an intermediate fixing member that holds the portion between the ends of the movable member, that is, the intermediate portion.

FIG. 2 is a perspective view of the movable tubular body 40 held by the holding device 10. FIG. The movable tubular body 40 includes a first tubular body 42, a second tubular body 44, a third tubular body 46, a fourth tubular body 48, a fifth tubular body 50, a sixth tubular body 52, a seventh tubular body 54, and 5 5 swivel joints 56, and these tubular bodies are connected by five swivel joints 56 so as to be bendable. In this embodiment, the term “bendable” means that the inclination of the tubular bodies changes with the swivel joint 56 as a node by moving (rotating) the tubular bodies with respect to the swivel joint 56 . In this way, by changing the inclination of the tubular bodies, the movable tubular body can be deformed (moved) as a whole. The first tubular body 42 to the seventh tubular body 54 are cylindrical members. A swivel joint 56 flexibly connects the two tubes while maintaining tube function. The movable tubular body 40 composed of a plurality of tubular bodies bendably connected by a plurality of swivel joints 56 becomes a freely deformable (movable) pipe with the swivel joints 56 as nodes.

In the example shown in FIG. 2, the first connecting pipe 60 and the second connecting pipe 62 are members of equipment to which the movable pipe body 40 is attached. The movable tubular body 40 is attached to the equipment in the attachment shape shown in FIG. The holding device 10 according to this embodiment holds the movable tubular body 40 so that the movable tubular body 40 has the mounting shape shown in FIG. 2 .

FIG. 3 is a diagram showing a state in which the movable tubular body 40 is held by the holding device 10. As shown in FIG. FIG. 3(a) is a front view, and FIG. 3(b) is a right side view. The first clamping member 14 of the retainer 10 holds the first tube 42 and the second clamping member 16 holds the second tube 44 . Also, the third clamp member 18 holds the sixth tubular body 52 and the fourth clamp member 20 holds the seventh tubular body 54 . Additionally, the fifth clamp member 22 holds the fourth tubular body 48 . Thereby, the movable tubular body 40 is held in the mounting shape shown in FIG.

Next, a method for attaching the movable tubular body 40 to equipment will be described. With the movable tubular body 40 held by the holding device 10 , the holding device 10 is transported to the vicinity of the facility where the movable tubular body 40 is attached. The holding device 10 is positioned at a position where the first connecting pipe 60 faces the first pipe body 42 and the second connecting pipe 62 faces the seventh pipe body 54 , and the first connecting pipe 60 faces the first pipe body 42 . , and the second connecting pipe 62 is connected to the seventh pipe 54, whereby the movable pipe 40 is attached to the equipment. After that, by removing the bolts (not shown) fixing the first clamp member 14 to the fifth clamp member 22 to the beam member 12, the holding of each tubular body by each clamp member is released, and the movable tubular body 40 is released. The holding device 10 is removed. In this way, the movable tubular body 40 is attached to the equipment.

Although FIG. 1 and FIG. 3 show an example in which the holding device 10 has five clamping members, the present invention is not limited to this. The holding device 10 has at least two clamping members: a first tubular body 42 provided at both ends of the movable tubular body 40, and a first clamping member 14 and a fourth clamping member 20 that hold a seventh tubular body 54. It's fine if you have it. As a result, the first pipe 42 and the seventh pipe 54 at both ends of the movable pipe 40 attached to the first connecting pipe 60 and the second connecting pipe 62 can be held and positioned by the clamp members, so that the operator can move the pipe. The tube 40 can be easily attached to equipment.

Further, the holding device 10 according to the present embodiment is held by the fourth clamp member 20 and the axis line of the first tubular body 42 provided at one end of the movable tubular body 40 held by the first clamp member 14. The axis line of the seventh tubular body 54 provided at the other end of the movable tubular body 40 is different. That is, the first clamping member 14 holds a tubular body with an axis different from that of the fourth clamping member 20 .

In equipment using the movable pipe body 40, there is a situation that it is impossible to connect with a straight pipe (that is, on the same axis). It is different from the axis (CL2). Therefore, by holding the first tubular body 42 and the seventh tubular body 54 having different axes with the first clamping member 14 and the fourth clamping member 20 of the holding device 10, these tubular bodies can be placed on the equipment side. It can be positioned relative to the first connecting tube 60 and the second connecting tube 62 . This allows the operator to easily attach the first tubular body 42 and the seventh tubular body 54 of the movable tubular body 40 to the first connecting pipe 60 and the second connecting pipe 62 on the facility side.

On the other hand, even if the first tubular body 42 and the seventh tubular body 54 at both ends are held, if the remaining second tubular body 44 to sixth tubular body 52 are not held, these tubular bodies will move unexpectedly. As a result, the pipe may come into contact with equipment or workers. If these tubular bodies come into contact with equipment, the equipment may be damaged, and if the tubular bodies come into contact with workers, the workers may be injured. Therefore, in the holding device 10, it is preferable to hold the first tubular body 42 and the seventh tubular body 54 at both ends as well as the second tubular body 44 to the sixth tubular body 52 other than the both ends by clamping members. As a result, it is possible to prevent the tubular body from unexpectedly contacting the equipment or the tubular body from contacting the worker. Furthermore, since the movable tubular body 40 can be attached to the facility in a state where the positions of all the tubular bodies are fixed, the movable tubular body 40 can be attached to the facility in a shape as planned.

Moreover, when holding each tubular body of the movable tubular body 40 with a clamp member, it is preferable to provide the clamp member of the holding device 10 so that every other tubular body of the movable tubular body 40 can be held. For example, in the case of a movable member consisting of five tubes and four swivel joints, the holding device would include clamping members for holding both end tubes and the central tube, and alternately holding these tubes. is preferably kept at The movement of the tubular bodies sandwiched between the central tubular body and the tubular bodies at both ends is restricted by holding the central tubular body and the tubular bodies at both ends even if they are not held by clamps. Therefore, these tubular bodies do not need to be held by clamping members, and by holding every other movable tubular body by clamping members, a large number of tubular bodies can be held with a small number of clamping members. can. It should be noted that, in places where there is little risk of sudden movement of the tubular bodies even if they are not held by the clamping members, the clamping members do not have to hold every other tubular body, and for example, every two tubular bodies may be held.

FIG. 4 is a front view showing the holding device 10 before and after extension. FIG. 4(a) is a front view showing a state before the beam member 12 is extended, and FIG. 4(b) is a front view showing a state after the beam member is stretched. A method for extending the beam member 12 will be described with reference to FIG.

The beam member 12 has an elastic portion. The telescoping portion is composed of a first fixing member 28 and a second fixing member 30 . The extension of the beam member 12 is performed in the following steps (1) to (4).
(1) Attach the suspension device 70 having two chain blocks 76 , two chains 78 , an upper jig 72 and a lower jig 74 to the first body portion 24 and the second body portion 26 .
(2) Remove the bolts that fix the first fixing member 28 to the second body portion 26 and the second fixing member 30 to the second body portion 26 .
(3) Extend the chain block 76 to move the second body portion 26 downward.
(4) The first fixing member 28 and the second main body portion 26 and the second fixing member 30 and the second main body portion 26 are fastened with bolts so that the first fixing member 28 and the second fixing member 30 are connected to the second main body portion. 26, and then the suspension device 70 is removed.

By extending the beam member 12 in this way, the size of the holding device 10 while holding the movable tubular body 40 (see FIG. 2), that is, the shape (end) of the movable tubular body 40 held by the holding device 10 spacing between parts) can be varied. As a result, for example, when the movable tubular body 40 is attached in a narrow space in the facility, the beam member 12 is shortened and the distance between the ends of the movable tubular body 40 is shortened before being transported into the facility. After that, the beam member 12 is extended, the movable tubular body 40 is returned to the mounting shape, and the movable tubular body 40 can be mounted on the equipment. Also, the extended beam member 12 can be contracted using the suspension device 70 .

When the beam member 12 is extended, only the tubular bodies at both ends are held by the clamp members, and the holding of the other tubular bodies may be loosened or released. Further, when extending the chain block 76 to move the second main body portion 26 downward, the first fixing member 28 and the second fixing member 30, which are maintained in a fixed state with the first main body portion 24, are moved to the second You may use it as a guide when moving the main-body part 26 downward. Furthermore, one of the bolt holes provided in the first fixing member 28 and the second fixing member 30 is an elongated hole, and the bolt in the elongated hole is loosened without being removed, and the second body portion 26 is attached in that state. You can move it downwards. As a result, the second main body portion 26 is positioned by the first fixing member 28 and the second fixing member 30 during the downward movement, so that the downward movement of the second main body portion 26 is stabilized. Moreover, in FIG. 4, although the example which expands and contracts the beam member 12 using the suspension apparatus 70 which has the chain block 76 was shown, it does not restrict to this. Instead of the suspension device 70, a jack may be used to extend and contract the beam member 12. FIG.

As described above, by using the holding device 10 according to the present embodiment, the movable tubular body 40 can be held at a position corresponding to the positions of the first connecting pipe 60 and the second connecting pipe 62 on the equipment side. Thereby, the operator can easily attach the movable tubular body 40 to the equipment.

In the present embodiment, an example of holding the movable tubular body 40 by the holding device 10 has been described. There may be. For example, when a flexible hose is held by the holding device 10, the holding device 10 may have end fixing members capable of holding both ends of the flexible hose having different axes. As a result, both ends of the flexible hose can be held at positions corresponding to the positions of the first connecting pipe 60 and the second connecting pipe on the equipment side, and the operator can easily attach the flexible hose to the equipment. Moreover, although the present embodiment has been described using an example of the holding device 10 in which the beam member 12 has an expandable portion, the present invention is not limited to this. For example, when there is space in the facility, and it is not necessary to expand and contract the beam member 12 (that is, when there is no need to change the shape of the movable tubular body 40), the beam member 12 does not have an expandable portion. may
