DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe supporting device for supporting a pipe on an object.

[0002]

2. Description of the Related Art As shown in FIG. 3, various metal pipes K are arranged around an engine such as a jet engine. In order to fix the pipe K to an engine body E, a pipe K is fixed at a predetermined position. A clamp (support device) C is provided. The pipe K is positioned according to its shape by the clamp C.

[0003]

However, although the conventional clamp C has a function of positioning the pipe K in the vertical, horizontal, and front-rear directions, the clamp C restricts the rotational movement of the pipe K about its axis. That is, it does not have a function of positioning in the twist direction. That is, the conventional clamp C is a cylindrical member as shown in FIG. 4, and the pipe K is inserted through the inside of the cylindrical member and fixed by the bolt B or the like. In this case, by supporting a plurality of predetermined positions of the pipe K with the clamp C, the movement in the up-down, left-right, front-rear directions is restricted, but the movement of the pipe K in the twisting direction is not restricted. Therefore, the pipe K may be twisted. In particular, when the pipe K is mounted, the pipe K may be mounted on the engine body E without being positioned sufficiently (in a twisted state). If the engine body E is driven while the pipe K is twisted and attached, the pipe K may be displaced in the twisting direction due to vibration. Then, during the operation of the engine body E, the pipes K come into contact with each other or the pipe K
And the engine body E may come into contact with each other, causing damage to the pipe K and fuel flowing through the pipe K to flow out. In this case, safety is reduced, for example, there is a risk that the fuel may catch fire.

[0004] Even when the pipe K is attached after the positioning in the torsional direction is accurately performed, the pipe K may be twisted during driving of the engine because the conventional clamp C does not have a sufficient restraining force in the torsional direction. In this case, the movement of the pipe K in the torsion direction can be restrained to some extent by tightening the clamp C with the bolt B, but a problem such as damage to the pipe K occurs.

The present invention has been made in view of such circumstances, and can accurately position a pipe at the time of disposition, and can also be used when an external force such as vibration during engine operation is applied. Another object of the present invention is to provide a pipe supporting device capable of stably supporting a pipe and improving safety.

[0006]

In order to solve the above-mentioned problems, a pipe support device according to the present invention is a pipe support device for supporting a pipe on an object, comprising: a tubular holding portion fixed to the pipe; A cylindrical clamp portion fixed to an object and capable of supporting the holding portion, an engaging portion provided on an outer surface of the holding portion and having a predetermined shape, and an engaging portion provided on the clamp portion; And an engaged portion that restricts movement of the pipe in the torsion direction by being engaged.

[0007] According to the present invention, by engaging the engaging portion provided on the outer surface of the holding portion fixed to the pipe with the engaged portion provided on the clamp portion, the torsion of the pipe at the time of mounting is achieved. And the positioning in the twisting direction (rotational direction) can be performed accurately and stably. Further, even after being attached to the object, the piping is prevented from being displaced in the twisting direction. Therefore, the pipes are prevented from being damaged by preventing the pipes from contacting each other or the pipes and the object, so that the safety during operation is improved.

In this case, the engaging portion may be a projecting portion projecting radially outward from the outer surface of the holding portion, and the engaged portion may be provided on the clamp by a notch portion engageable with the projecting portion. By doing so, accurate positioning of the piping and suppression of torsion can be realized.

Alternatively, as the engaging portion, the cross-sectional shape in the direction perpendicular to the axis of the outer surface of the holding portion is polygonal, and as the engaged portion, the cross-sectional shape of the inner surface of the clamp portion is polygonal according to the outer surface of the holding portion. This also makes it possible to achieve accurate positioning and suppression of torsion at the time of installation of the pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a pipe support device according to the present invention will be described below with reference to the drawings. FIG.
FIG. 1 is a perspective view for explaining a first embodiment of a pipe support device of the present invention. Note that the pipe support device in the present embodiment is attached to a predetermined position of a pipe K provided in an engine body (object) E as shown in FIG.

In FIG. 1, a pipe support device 1 includes a pipe K
And a clamp portion 3 that can support the holding portion 2. And the clamp part 3
Is fixed to the engine body (object) E as shown in FIG.

The holding portion 2 is formed in a tubular shape corresponding to the shape of the outer surface of the pipe K, and has an insertion portion 2a through which the pipe K can be inserted. At this time, the pipe K and the holding portion 2 are in a state of being fixed by, for example, performing arc welding or the like after the pipe K is inserted into the insertion portion 2a.

An outer surface of the holding portion 2 has a projecting portion 4 projecting outward in a direction (radial direction) perpendicular to the axis of the cylindrical shape.
It has. In the present embodiment, two protrusions 4 are provided, and are integrally formed with the holder 2 at positions facing each other with respect to the axis of the holder 2. The number of the protrusions 4 can be set to one or two or more.

The clamp portion 3 includes a cylindrical main body 3H and a flange 3 connected to the engine main body (object) E.
T, and the cylindrical main body 3H has an insertion portion 3a through which the holding portion 2 can be inserted. That is, the inner diameter of the clamp 3 is set to be substantially the same as or slightly larger than the outer diameter of the holder 2.

At a predetermined position of the main body 3H of the clamp portion 3, a notch 5 is formed along the axial direction from one end to the other end. The notch 5 is formed at a position corresponding to the protrusion 4 provided on the holder 2, and can support the protrusion 4 inside.

A method of arranging the pipe K with respect to the engine body E by the pipe support device having the above-described configuration will be described. Before attaching the pipe K to the engine body E, the three-dimensional shape of the pipe K is set so that twisting does not occur when the pipe K is attached and the position in the twist direction (rotation direction) is a desired position. Accordingly, the mounting angle and the mounting position of the holding unit 2 in the torsion direction with respect to the pipe K are set in advance so that the projecting portion 4 faces in a predetermined direction. Then, as shown in FIG. 1A, the pipe K and the holding portion 2 are fixed by welding or the like. At this time, the fixing position of the holding portion 2 with respect to the pipe K can be set to an arbitrary position and an arbitrary number, but as shown in FIG.
By disposing the holding portion 2 in the vicinity, even if the pipes K are displaced, contact between the pipes K and the pipe K and the engine body E can be suppressed.

Next, as shown in FIG.
Is held by the clamp unit 3. That is, the protrusion 4 oriented in a predetermined direction is supported inside the cutout 5. Then, with the protrusion 4 of the holding part 2 and the notch 5 of the clamp part 3 engaged with each other, the flange part 3T of the clamp part 3 is placed at a predetermined position of the engine body E by using, for example, bolts and nuts. Fix it. As described above, the pipe K is provided for the engine body E.

At this time, when the pipe K is attached to the engine body E by the holding portion 2 and the clamp portion 3, the position of the pipe K in the rotation direction is set to a desired position so that the pipe K is not twisted. The positions at which the protruding portions 4 and the notches 5 are formed are set in advance based on the three-dimensional shape of the pipe K. Therefore, when the pipe K is provided, the pipe K is not twisted.

As described above, the holding portion 2 having the protrusion 4 as an engaging portion is fixed to the pipe K,
A protrusion 4 is provided on a clamp 3 for supporting the holding portion 2.
With the provision of the notched portion 5 as an engaged portion to be engaged with the engine main body E, the positioning when mounting the pipe K to the engine main body E can be performed stably, and the pipe K can be operated even after the mounting. Generation of K twist (movement in the rotation direction) can be suppressed. That is, since the displacement of the pipe K is suppressed, contact between the pipes K and contact between the pipe K and the engine body E can be prevented.
Therefore, since damage to the pipe K can be prevented, problems such as fuel leakage can be prevented beforehand, and safety can be improved.

When arranging the pipe K, the pipe K is adjusted in accordance with the three-dimensional shape so that the pipe K is not twisted and the position of the pipe K in the rotation direction is a desired position. Since the arrangement work is performed after setting the formation positions of the protruding portion 4 and the notch portion 5 in advance, the positioning can be quickly performed without worrying about the occurrence of twisting of the pipe K at the time of arrangement. it can. Therefore, the arranging work can be performed stably and quickly, so that the workability is improved.

The installation position and the number of the pipe supporting devices 1 can be set arbitrarily. However, as shown in FIG.
Even if is displaced in the rotation direction, since it supports the vicinity of the bent portion M where the radius of rotation increases, it is possible to effectively prevent the pipe K from contacting.

Next, a second embodiment of the pipe support device of the present invention will be described with reference to FIG. Here, the same reference numerals are used for the same or equivalent components as those of the above-described first embodiment, and the description thereof will be simplified or omitted.

In FIG. 2, a pipe support device 1 is provided with a pipe K

The inner surface 3A is formed so as to correspond to the shape of the outer surface 2A of the holding unit 2, and in the present embodiment, the cross-sectional shape of the inner surface 3A of the clamp unit 3 is formed as a hexagon.

In this embodiment, the holding unit 2
The directions of the vertices of the hexagons of the outer surface 2A of the inner surface 3A and the inner surface 3A of the clamp portion 3 are set in advance so that twisting does not occur when the pipe K is attached to the engine body E.

Then, the holding portion 2 and the clamp portion 3 are engaged with each other so that each vertex of the hexagon of the outer surface 2A of the holding portion 2 corresponds to each vertex of the hexagon of the inner surface 3A of the clamp portion 3. As a result, the pipe K is
At the time of installation around or during operation after installation, twisting and movement of the pipe K in the rotation direction can be suppressed.

In the second embodiment, the cross-sectional shape of each of the inner surface 2A of the holding portion 2 and the outer surface 3A of the clamp portion 3 has been described as being hexagonal.
Needless to say, a desired effect can be obtained by forming an arbitrary polygonal shape.

In the first embodiment, the projection 4 has been described as being engaged with the notch 5 by being inserted from the upper side in the figure, but a through hole penetrating in a predetermined position of the clamp 3 in the radial direction. It is also possible to provide a configuration in which the protrusion 4 is engaged with the through hole. In this case, the clamp portion 3 may be deformed so as to be pushed and spread from the flange portion 3T, and after the protrusion 4 is engaged with the through hole, the clamp portion 3 may be deformed so as to be tightened.

The pipe support device 1 of the present invention can be applied not only to pipes mounted on a jet engine, but also to pipes provided for a structure (for example, a motor) that generates vibration. is there.
