Description

[Detailed Description of the Invention] The present invention relates to a piping support device used to support various types of piping such as water piping, gas piping, marine piping, plant piping, and electric transmission piping.

As a support device for supporting various types of piping, there is a support device disclosed in, for example, Japanese Utility Model Publication No. 55-48231.

In this product, a rubber piece is glued onto a support base, a strip made of tetrafluoroethylene resin is glued to the top side of this rubber piece to form a bearing surface, and the piping is placed on this bearing surface. Then, the piping is attached to the support base using U bolts.

With such a device, a piece of rubber is interposed between the piping fixed on the bearing surface and the support base, so if the piping is bent due to vibration etc. This bending of the piping is absorbed by the rubber piece to prevent the piping from being unreasonably deformed or damaged.

However, if the rubber piece alone is used to absorb the deflection of the piping during vibration, and to support the piping on a support stand, the rubber piece itself does not have such excellent elastic support power. However, as the weight of the pipe increases or the vibration of the pipe increases, the load due to the vibration of the pipe increases on the rubber piece.
There was a problem in that the rubber piece was crushed to a large extent, and as a result, the piping was bent greatly, leading to deformation and damage.

In addition, when placing piping on a bearing surface and attaching the piping to a support stand with U bolts, if the center of gravity of the piping is shifted from the center position of the bearing surface, eccentric pressing force from the piping may be applied. This caused the rubber pieces to shrink and deform in a lopsided state, which caused the bearing surface to tilt and cause the piping to fall off the bearing surface. Falling off of piping due to such a shift in the position of the center of gravity has occurred not only during installation but also after installation due to external forces or the like.

The present invention was devised in view of the above circumstances, and its purpose is to effectively absorb the large load caused by vibrations of the piping, and to maintain the structure of the piping. It is an object of the present invention to provide a piping support device that can effectively prevent deformation and damage to the piping, and can also reliably prevent the piping from falling off due to displacement of the center of gravity.

In order to achieve the above object, the piping support device of the present invention has a pair of support sections interposed on both sides of the rubber piece in the width direction between the support base and the support section, and one end of the pair of support sections. are each fixed to the support part, and the other end thereof is provided with an upward movement regulating member that passes through the support base and abuts against the lower surface side of the support base, and is further located between the support base and the support part. A spring member is provided on each of the pair of support pillars for biasing the support part upward through the support pillars.

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

In the figure, reference numeral 1 denotes a support base, on the upper surface of which a rubber piece 2 is adhered, and on the upper surface side of the rubber piece 2 a support portion 3 is provided.

The support part 3 includes a support part main body 3a made of a steel plate formed in an arc shape along the outer circumferential surface of the pipe 5, and a support part main body 3a made of a steel plate having excellent electrical insulation properties and low resistance. It is provided with a bearing portion 3b to which a tetrafluoroethylene resin plate having a coefficient of friction is adhered, and the upper surface of the bearing portion 3b is a bearing surface 3c.

Further, a pair of support portions 6 are provided on the lower surface side of both ends of the support portion main body 3a, that is, on both sides in the width direction of the rubber piece 2.
7 is provided, and one end of each of the support columns 6 and 7 is fixed to the lower surface of the support body 3a.

The support columns 6 and 7 have flanges 6a and 7a formed approximately at their central portions, and these flanges 6a and 7a
A plurality of disc springs 8 and 9 are interposed as spring members between the washer 6b and 7b on the support base 1.
Then, the threaded parts 6c, 7c formed at the ends of the pillar parts 6, 7 are passed through the washers 6b, 7b and the support base 1, and the through ends are used as upward movement regulating members for the pillar parts 6, 7. By screwing nuts 10, 10 together and applying them to the lower surface of the support base 1, the support columns 6, 7 are interposed between the support base 1 and the support body 3a.

Furthermore, the bearing surface 3c of the support portion 3 includes:
A pipe 5 appropriately selected according to the flow rate of the fluid is mounted, and the pipe 5 is connected to a U-bolt 1.
1 is attached to the support stand 1 as shown in FIG. Note that a concave groove (not shown) is formed in the inner peripheral surface of the U-bolt 11, and a tetrafluoroethylene resin plate 12 is inserted and fixed into this groove. Piping 5 by 12
The upper half of the outer peripheral surface is directly supported.

However, with such a configuration, now the piping 5
Even if a large deflection occurs due to an earthquake or the shaking of the ship's body in the case of marine piping, there is a spring member in addition to the rubber piece 2 between the support part 3 that supports the piping 5 and the support base 1. Since the struts 6 and 7 are interposed with (disc springs 8 and 9), these rubber pieces 2 and the spring members (disc springs 8 and 9) of the struts 6 and 7 are interposed.
9) work together to absorb the deflection of the piping 5, and at the same time limit the unnecessary deflection of the piping 5 that tends to occur when only rubber pieces are used, thereby preventing deformation or damage to the piping 5. can be effectively prevented.

Furthermore, by interposing spring members (disc springs 8, 9) in the support columns 6, 7, the support columns 6, 7 can be elastically deformed upward and downward, so that the conventional rubber pieces can Piping 5, which was an advantage when only
Error absorption during installation on the supporting device is not hindered in any way, and deformation and damage to the piping 5 can be effectively prevented while taking advantage of the conventional advantages.

In addition, with the above configuration, when the pipe 5 is strongly abutted against the support part 3 with the U-bolt 11 or after the pipe 5 is attached to the support base 1, the pipe 5
Even if the center of gravity of the support part 3 deviates from the center position of the support part 3, the spring members 8 and 9 of the support parts 6 and 7 can restrict the inclination of the support part 3 to a predetermined limit. In other words, since the maximum amount of inclination of the support part 3 can be regulated so that the pipe 5 does not fall off the support part 3, the pipe can be prevented from falling off from the support part no matter what happens.

Further, the outer circumferential surface of the substantially lower half of the pipe 5 is supported by a bearing surface 3c made of tetrafluoroethylene resin provided in the support part 3, and the outer circumferential surface of the substantially upper half of the pipe 5 is supported by U bolts. Since it is supported by the tetrafluoroethylene resin plate 12 provided on the inner circumferential surface of the pipe 11, the temperature of the fluid in the pipe 5 is reduced due to the low friction coefficient of the tetrafluoroethylene resin, that is, the good sliding property. Even if the pipe 5 expands or contracts due to a change in temperature or a change in the ambient temperature, the pipe 5 can be easily slid against the support 3 and the U-bolt 11. thermal expansion,
Deformation and damage due to shrinkage can also be effectively prevented.

Moreover, the tetrafluoroethylene resin has excellent insulation resistance, so if the piping 5 is supported on the tetrafluoroethylene resin bearing surface 3c and the tetrafluoroethylene resin plate 12, seawater It is also possible to effectively prevent electrolytic corrosion of the piping 5 caused by the like, and is highly effective for marine piping such as tankers.

In the above embodiment, the spring members interposed between the support columns 6 and 7 are disc springs 8 and 9, but it is of course possible to use coil springs as the spring members, for example.

As explained above, in the piping support device of the present invention, a pair of support sections are interposed on both sides of the rubber piece in the width direction between the support base and the support section, and one end of each of the pair of support sections is An upward movement regulating member is provided which is fixed to the support part and has its other end penetrated through the support base and abuts against the lower surface side of the support base, and further includes a pair of upward movement regulating members located between the support base and the support part. Since a spring member is provided in each of the support sections to urge the support section upward through the support section, even if the piping tends to flex significantly due to vibration, etc., the spring member The piece and the spring member of the support support effectively absorb the moisture, and at the same time, limit the unnecessary bending of the pipe that tends to occur when only rubber pieces are used, effectively preventing deformation and damage to the pipe. can be prevented.

Moreover, by interposing a spring member in the support column, the support column can be elastically deformed upward and downward, which is an advantage of the conventional piping support device using only rubber pieces. Error absorption during installation is not hindered in any way, and deformation and damage to the piping 5 can be effectively prevented while taking advantage of the conventional advantages.

Furthermore, even if the center of gravity of the pipe deviates from the center position of the support when the pipe is firmly attached to the support using U-bolts or after the pipe is attached to the support, the spring of the support Because the inclination of the support part can be regulated to a predetermined limit by the member, in other words, the maximum amount of inclination of the support part can be regulated to prevent the piping from falling off the support part.
No matter what happens, the piping can be reliably prevented from falling from the support, and safety can be dramatically improved.
