Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pipe support device for supporting a pipe on an object.
[0002]
[Prior 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 pipes K to the engine body E, clamps (support devices) at predetermined positions of the pipes K are provided. C is provided. And the piping K is positioned according to the shape by the clamp C.
[0003]
[Problems to be solved by the invention]
However, the conventional clamp C has a function of positioning the pipe K in the vertical, horizontal, and front-rear directions. However, the function of regulating rotational movement around the axis of the pipe K, that is, positioning in the torsional direction. Does not have. That is, the conventional clamp C is a cylindrical member as shown in FIG. 4, and the pipe K is inserted into the cylindrical shape 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 vertical and horizontal directions and the front-rear direction is restricted, but the movement of the pipe K in the twisting direction is not restricted. Therefore, the piping K may be twisted. In particular, when the piping K is attached, the positioning may not be sufficiently performed (the twisted state) may be attached to the engine body E. If the engine body E is driven with the pipe K being twisted and attached, the pipe K may be displaced in the twisting direction due to vibration. Then, while the engine main body E is being driven, the pipes K may come into contact with each other, or the pipe K and the engine main body E may come into contact with each other, so that the pipe K may be damaged and fuel flowing through the pipe K may flow out. In this case, the safety is lowered, for example, there is a risk of ignition of the fuel.
[0004]
Even when the pipe K is attached after positioning in the torsion direction is performed with high accuracy, the pipe C may be twisted while the engine is driven because the conventional clamp C does not have sufficient restraining force in the torsion direction. In this case, tightening the clamp C with the bolt B can restrict the movement of the pipe K in the torsional direction to some extent, but causes problems such as damage to the pipe K.
[0005]
The present invention has been made in view of such circumstances, and can accurately position the piping at the time of installation, and when an external force such as vibration at the time of driving the engine is applied, for example, An object of the present invention is to provide a piping support device that can stably support piping and improve safety.
[0006]
