Description

VIBRATION REDUCTION DEVICE

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration reduction device, and more particularly, to a vibration reduction device for a ship piping capable of reducing vibration of various pipes installed on a ship.

The piping installed inside the ship is fixed or supported on the wall of the ship by using a metal structure such as a clamp to be fixed to the ship.

This method is governed by the number of clamps that control the stresses and vibrations that occur in the piping.

If the number of clamps is small, the allowable stress of the pipe is satisfied, but there is a problem of increased vibration. If the number of clamps is increased to increase the constraint, the vibration decreases, but the allowable stress is exceeded due to excessive constraint. .

Therefore, it is an object of the present invention to provide a vibration reduction apparatus for a ship piping which can reduce the problems due to vibration while satisfying an allowable stress according to an appropriate constraining condition.

In order to achieve the above object, a vibration reduction device according to an embodiment of the present invention includes a first support member and a second support member which are installed inside a ship and support a pipe, a first support member and a second support member, And a resilient member positioned between the spacer and the first support member, and between the spacer and the second support member, respectively.

The elastic member may have a hole through which the pipe passes.

The elastic member may be fixed to the gap member.

The spacer may be fixedly installed in the pipe.

The first support member and the second support member may be screwed to the piping, respectively.

The spacer and the elastic member may be fixed to the first and second support members by a threaded coupling.

The first support member and the second support member may each include a first member in a direction crossing the pipe, and a second member extending from both ends of the first member toward the ship.

The first support member and the second support member may have a concave portion corresponding to the pipe and recessed along the outer shape of the pipe.

When the piping is fixed to the ship by using the vibration reduction device as in the present invention, the vibration applied to the fixing device for fixing the piping can be reduced to minimize damage due to vibration.

Further, in the present invention, it is possible to reduce the vibration due to the fluid moving in the pipe.

Hereinafter, a vibration reduction device according to an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view schematically showing a structure of a vibration damping device according to an embodiment of the present invention, and FIG. 2 is a schematic side view of the vibration damping device shown in FIG.

1 and 2, a vibration reduction apparatus 1000 according to an embodiment of the present invention includes a first support member 202 and a second support member 204 which are spaced apart from each other, A gap member 300 located between the first support member 202 and the second support member 204 and a spacer member 300 between the first support member 202 and the spacer member 300 and between the second support member 204 and the spacer member 300. [ And an elastic member 400 disposed between the elastic members 400, respectively.

The first support member 202 and the second support member 204 are fixed to the inside of the ship, that is, the wall or the ceiling, respectively, and support the piping 100 in the ship. The first support member 202 and the second support member 204 may have a structure in which the pipe 100 is supported at a plurality of points and one side is open.

In one embodiment of the present invention, not only the piping installed in the vessel but also the piping can be installed to reduce the vibration.

The first support member 202 and the second support member 204 are disposed in a direction intersecting the pipe 100 and include a first member 22 on which the pipe 100 is placed, And a pair of second members (24) each extending from the ship toward the ship. The first member 22 and the second member 24 may be separately formed and then connected to each other, but the present invention is not limited thereto. The first member 22 and the second member 24 can be formed by bending one member.

An engagement plate 26 is connected to one end of the second member 24 and the first support member 202 and the second support member 204 can be screwed to the ship through the engagement plate 26, . The coupling plate 26 is a separate member and can be attached to the second member 24 by welding. However, the coupling plate 26 may be formed by bending the edge of the second member 24.

The spacing member 300 is fixed to the pipe by welding or the like and may be positioned approximately between the first support member 202 and the second support member 204. The spacer 300 maintains a gap between the first support member 202 and the second support member 204 with a rigid material.

1 and 2, the spacing member 300 formed separately is installed in the pipe 100. However, the spacing member 300 is not limited thereto and may be a flange for connecting the pipe and the pipe.

The elastic member 400 is formed with a hole through which the pipe 100 passes. The plane shape of the hole may be a cross-sectional shape of the pipe, and may be circular, for example. The elastic member 400 may be fixed to the spacer 300 with an adhesive.

The width of the elastic member 400 may be equal to the width between the spacing member and the first supporting member, the spacing member, and the second supporting member, and is disposed so as to be in close contact with the first supporting member 202 and the second supporting member 204 .

The elastic member 400 is for absorbing impact applied to the pipe or vibration of the pipe, and may be a material that is highly frictional, can expand or contract, and may be made of a rubber material.

As described above, when the elastic member is provided between the support members as in the embodiment of the present invention, the vibration caused by the movement of the fluid flowing in the pipe can be effectively reduced.

3 to 6 are schematic views of a vibration damping device according to another embodiment of the present invention.

A recessed portion V may be formed in at least one member of the first member 22 and the second member 24 of the vibration reduction device 1002 shown in Fig. The concave portion V may be formed in a portion contacting or facing the pipe 100 and the concave portion V may be formed in a concave shape along the outer shape of the pipe 100 so as to surround the outside of the pipe 100 .

As described above, when the concave portion V is formed, the contact area between the first member 22 and the second member 24 and the pipe 100 increases, and the pipe 100 can be more stably supported.

The spacing member 300 of the vibration reduction apparatus 1004 shown in Fig. 4 is screwed to the piping 100. That is, if a thread S is formed on the inside of the spacer 300 and on the outside of the pipe 100 and a screw thread is formed thereon, a separate welding process for fixing the spacer 300 to the pipe 100 is not required.

The elastic member 400 and the spacing member 300 of the vibration reduction apparatus 1006 shown in Fig. 5 can be coupled to the second member 24 with at least one threaded type coupling body 33. Fig. The threaded joint 33 may be composed of a bolt and a nut. The coupling body 33 is formed from the second member 24 of the first supporting member 202 to the second member 24 of the second supporting member 204 so that the elastic member 400, The material 300 can be bonded at the same time.

The elastic member 400 may be separately fixed to the gap member 300 or the gap member 300 may not be separately fixed to the pipe 100 by using the coupling member 33. [

The second member 24 of the vibration reduction apparatus 1008 shown in Fig. 6 and the pipe 100 can be screwed together. The screw connection can be screwed by rotating the pipe 100 or rotating the second member 24.

As described above, when the second member 24 and the pipe 100 are screwed together, it is possible to minimize the transmission of vibration due to the fluid movement by fixing the pipe 100 to the second member 24 more strongly.
