Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a bottom support type pipe support device.

[0002]

[Prior Art]

 When laying pipes, the pipes whose positions move due to thermal expansion, such as turbine pipes, are generally hung and supported from the ceiling of the structure, etc. by using an elastic pipe support device such as a spring hanger. is there.

However, when the pipe displaced by the thermal expansion cannot be hung and supported from above by using a spring hanger, for example, the pipe displaced by the thermal expansion is entangled under the equipment such as a turbine. In some cases, such as when a pipe that displaces due to thermal expansion is installed underneath another pipe that displaces due to thermal expansion, replace the spring hanger of the type suspended from the ceiling with A bottom receiving type pipe support device such as a hanger that is supported from the floor will be used.

The above-mentioned bottom support type pipe support device is as shown in FIG.

In the figure, 1 is a pipe that is displaced by thermal expansion, and 2 is a base such as a frame or floor.

A cylindrical container-shaped hanger body 4 having an opening 3 on the upper surface and extending in the vertical direction is provided on the upper portion of the base 2, and a disc-shaped hanger body 4 is slidable in the vertical direction inside the hanger body 4. The elevating member 5 is accommodated, and the coil spring 6 for urging the elevating member 5 upward is accommodated inside the hanger body 4 and below the elevating member 5.

Then, an elevating body 7 having a cylindrical shape extending in the vertical direction and which can freely move in and out from the opening 3 on the upper surface of the hanger body 4 is fixed to the upper surface of the elevating member 5 by welding or the like, and the upper surface of the elevating body 7 is bolted. A through hole 8 is formed, and a headless bolt body 10 screwed with a lock nut 9 is inserted into the bolt through hole 8 to form a lower receiving spring hanger body 11.

A horizontal rectangular pipe support plate 12 is welded and fixed to the upper end of the bolt body 10 of the lower support type spring hanger body 11, and a horizontal slide plate 13 is slidably mounted on the upper part of the pipe support plate 12. Place the pipe fixing jig 14 on the slide plate 13 to hold the outer periphery of the pipe 1 in place, and when the pipe 1 thermally expands, the direction in which the pipe 1 moves by design (each pipe 1 is different; The slide guide 15 is welded and fixed to the pipe receiving plate 12 so as to allow the slide plate 13 to slide with respect to the longitudinal direction of the pipe 1), thereby forming the pipe receiving portion 16.

In the bottom receiving type pipe support device, of the movement of the pipe 1 due to thermal expansion, the upward and downward movement is allowed by the elevating and lowering of the portion above the elevating member 5 due to the expansion and contraction of the coil spring 6. By design, the pipe 1 is allowed to move in the direction in which the pipe 1 moves at the time of thermal expansion by sliding the portion above the slide plate 13 along the slide guide 15.

[0010]

[Problems to be solved by the device]

 However, the above-mentioned conventional bottom support type pipe support device has the following problems.

That is, the pipe 1 may move as designed when it thermally expands, but sometimes the pipe 1 does not move as designed. Due to the thermal expansion, for example, the pipe 1 may be moved as shown in FIG. When the slide guide 15 cannot fully allow the slide plate 13 to slide, the slide guide 15 is pushed by the slide plate 13 and the pipe receiving plate integrated with the slide guide 15 is provided. 12 is tilted, which causes damage such as bending of the bolt body 10 or distortion of the lower support type spring hanger body 11, and the lower support pipe support device will no longer function. .

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a bottom support type pipe support device capable of preventing damage even when the pipe does not move as designed. is there.

[0013]

[Means for Solving the Problems]

 The present invention supports the lower surface of a horizontal pipe receiving plate 12 so that it can be lifted and lowered by a lower support type spring hanger body 11, and a horizontal slide provided integrally with the pipe 1 on the upper surface of the pipe receiving plate 12. The plate 13 is slidably arranged, and a slide guide 15 for guiding the slide plate 13 in the design moving direction of the pipe 1 when the pipe 1 thermally expands is provided on the pipe receiving plate 12, and further the pipe receiving plate 12 is provided. Vertically extending guide cylinders 18 are provided at at least three positions on the plate 12, and a vertically extending rod-shaped guide member 19 is movably inserted into the guide cylinder 18, and the lower end of the guide member 19 is attached to the base 2 It is related to a bottom receiving type pipe support device, which is characterized in that it is fixed to.

[0014]

[Action]

 According to the present invention, of the movement of the pipe 1 due to the thermal expansion, the vertical movement is allowed by the bottom spring hanger body 11, and the design pipe 1 moves when the pipe 1 thermally expands. Is allowed to slide by sliding the portion above the slide plate 13 along the slide guide 15.

When the pipe 1 does not move as designed and the slide guide 15 cannot allow the slide plate 13 to slide, the pipe receiving plate 12 tends to be tilted, but the pipe receiving plate 12 is a guide member. Since at least three positions are supported by 19, it is prevented from tilting, thereby preventing breakage, and when the pipe 1 cools and returns to its original position, the bottom support pipe support device functions. It is prevented from running out.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show an embodiment of the present invention.

In the drawings, the same components as those shown in FIGS. 3 and 4 are designated by the same reference numerals, and the description thereof will be omitted. Below, only the configuration unique to the present invention will be described. To go.

Overhanging portions 17 are formed at four corners of the pipe receiving plate 12, and guide tubes 18 extending in the up-down direction are inserted and fixed to the overhanging portions 17, and bar-shaped guides extending in the up-down direction are provided in the guide tubes 18. The member 19 is movably inserted and the lower end of the guide member 19 is fixed to the base 2.

Next, the operation will be described.

The operation of the bottom receiving type pipe supporting device itself is the same as that shown in FIGS. 3 and 4, and a description thereof will be omitted.

When the pipe 1 does not move as designed and is moved by thermal expansion, for example, in the direction of the arrow, and the slide guide 15 cannot allow the slide plate 13 to slide, the slide plate 13 Although the slide guide 15 is pushed by the slide guide 15 and the pipe receiving plate 12 integrated with the slide guide 15 tends to be inclined, since the corners of the pipe receiving plate 12 are supported by the guide members 19 at four points, the pipe receiving plate 12 cannot be inclined. This prevents damage such as bending of the bolt body 10 and distorting of the bottom receiving type spring hanger body 11, and when the pipe 1 cools and returns to its original position, the bottom receiving pipe It is prevented that the support device fails its function.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and the guide member may be provided at least at three or more places, and within the scope not departing from the gist of the present invention. Of course, various changes can be made.

[0024]

[Effect of the device]

 As described above, according to the bottom support type pipe support device of the present invention, it is possible to obtain an excellent effect of preventing damage when the pipe does not move as designed.
