[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension device in which a suspended object can be easily moved back and forth, right and left in a suspended state.

[0002]

2. Description of the Related Art A device such as a boiler which thermally expands during operation is supported in a suspended state. FIG. 2 shows a conventionally used suspending device. The suspension device includes a first device 11 fixed to a suspended object 14, a second device fixed to a fixed portion such as a ceiling, and a joining material 13 for joining the first device 11 and the second device 12. Is done. Each of the first device 11 and the second device 12 includes two weight plates 15 with a center plate 16 interposed therebetween, and pins 17 that rotatably penetrate the three plates 15 and 16. Two weight plates 15
Are fixed to the suspended object 14 and the fixed object, respectively.
The planes orthogonal to each other are defined as an X plane and a Y plane. First device 1
The three plates 15 and 16 of 1 exist on the X plane and the pin 17 is Y
Exists on a plane. Also, the three plates 15 of the second device 12,
16 is on the Y plane and pin 17 is on the X plane.

[0003]

When a force or displacement in the X direction is applied to the suspended object 14 due to thermal expansion or the like, the first device 1
An in-plane force is applied to the first weight plate 15, and the first weight plate 15 is rotated by the pin 17, so that no excessive force is applied to the weight plate 15. On the other hand, a force perpendicular to the Y plane in which the weight plate 15 exists is applied to the weight plate 15 of the second device 12, and the pin 17 does not rotate, so that an excessive force is applied to the weight plate 15. When a force or displacement in the Y direction is applied, a force in the in-plane direction is applied to the basis plate 15 of the second device 12 and the pin 17 rotates, so that an unreasonable force is not applied to the basis plate 15. On the other hand, a force perpendicular to the X plane in which the weight plate 15 is present is applied to the weight plate 15 of the first device 11 and rotation by the pin 17 does not occur, so that an excessive force is applied to the weight plate 15. As described above, when a force is applied in either the X direction or the Y direction, an in-plane force is applied to the basis plate 15 of one of the devices 11 or 12 and the rotation by the pin 17 is also applied. However, a force perpendicular to the in-plane direction in which the weight plate 15 exists is applied to the weight plate 15 of the other device 11 or 12, and the pin 17 does not rotate, and an excessive force is applied.

[0004] The present invention has been made in view of such a problem, and an object of the present invention is to provide a suspension device that does not generate an excessive force even when a force or displacement is applied to an object to be suspended.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, a first device attached to an object to be suspended, a second device attached to a fixing portion, and a second device attached to a fixed portion.
A suspension device comprising a device and a bonding material connecting the first device, and assuming an X plane and a Y plane orthogonal to each other,
The first device is present in the X plane, and has a first arc-shaped round bar attached to an object to be suspended, and a first arc-shaped bar having the first round bar slidably penetrating therethrough. A first flat plate attached to the outermost periphery of the first arcuate tube, wherein the second device is present in the Y plane, and is a second arcuate round bar attached to the fixed portion; The second round bar comprises a second arcuate tube slidably penetrating with a gap therebetween, and a second flat plate attached to the outermost periphery of the second arcuate tube. One end is connected to the first plate, and the other end is the second plate.
Connected to a flat plate.

[0006] When a force or displacement is applied in the X direction, the first device slides along the first arcuate round bar in the first device, so that no excessive force is generated. In the second device, since the second round bar and the second arc-shaped tube rotate within the range of the gap, no excessive force is generated. When a force or displacement is applied in the Y direction, the first
In the device, since the first round bar and the first arc-shaped tube rotate within the range of the gap, no excessive force is generated. In the second device, since the second arc-shaped tube slides along the arc-shaped second round bar, no excessive force is generated.

According to the second aspect of the present invention, the arc length of each of the arc-shaped tubes and the gap between each of the arc-shaped tubes and each of the round bars are determined in accordance with a rotation angle of rotation in a direction perpendicular to a plane to which each of the arc-shaped tubes belongs. Can be

When each arc-shaped tube rotates around the corresponding arc-shaped round bar, the rotation angle is limited by the gap between them and the arc length of the arc-shaped tube. The larger the gap and the shorter the arc length, the larger the rotation angle. Therefore, the arc length of each arc tube and the gap between the arc tube and the round bar are determined according to the expected rotation angle.

Further, the arc length of the first arc-shaped tube 6a and the arc length of the second arc-shaped tube 6b are determined by the displacement applied to the suspended object 4 so that each of the arc-shaped tubes 6a, 6b is in relation to each of the round bars 5a, 5b. It only depends on whether it can be rotated. If the gap is large and the arc length is short, the rotation angle increases. In a suspension device such as a boiler, the rotation angle due to the displacement is small, so it is not necessary to make the gap too large or to shorten the arc length.

Next, the operation will be described. Hanging object 4
Is displaced in the X direction, the first arc-shaped tube 6a slides along the first round bar 5a in the first device 1, and the second device 2

When displaced in the Y direction, the first device 1 rotates the first circular tube 6a around the first round bar 5a, and the second device 2 converts the second circular tube 6b to the second round bar 5b. Slide along. No excessive force is generated in any of the devices 1 and 2, and the suspended object 4 moves smoothly. In addition, the displacement in the direction combining the X direction and the Y direction can be easily endured by disassembling in the X direction and the Y direction.
