Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a pipe support device for collectively supporting a plurality of pipes for an air cylinder or the like.

(Prior Art) For example, in a casting core manufacturing apparatus, in order to arrange a large number of pipes for a die driving air cylinder for a core, as shown in FIG. _{1 to} n are installed at specified intervals.

Conventionally, when the mounting the respective pipes 2 ₁ ~n the supporting rod 1, as shown in FIGS. 4 and 5, the support rods 1
Pipe to form a plurality of flow holes 3, the female screw portion 9 is provided at one end of the pipe 2 ₁ ~n, screwed one end external thread portion 4a of the nipple 4, the nipple 4 at predetermined intervals in 2 ₁
After connecting to the pipes _{1 to} n, the pipes 21 to n are rotated to screw the other end male screw portion 4b of the nipple 4 into the flow holes 3 of the support rod 1.

However, when rotating the respective pipes 2 ₁ ~n, the respective pipes
2 ₁ ~n vertical portion 2a, against the adjacent pipe 2 ₁ ~n,
There is a possibility that the nipple 4 cannot be screwed into the flow hole 3 of the support rod 1. Therefore, as the installation procedure for each pipe 2 ₁ ~n, the distance L from the distal end to the vertical portion 2a, sequentially from those with the length H of the vertical portion 2a is short, attached to the supporting rod 1 at an appropriate interval Is being done.

In (invented Problems to be Solved) the conventional tube support device, the wrong attachment positions and attachment procedure of the pipes 2 ₁ ~n, can not be attached to the respective pipes 2 ₁ ~n the supporting rod 1 Therefore, it is necessary to carry out the mounting in accordance with a predetermined procedure, which causes a problem that the mounting work takes a very long time. In addition, even in the case to remove the once attached piping 2 ₁ ~n for repair and inspection, may be removed must be removed also piping other than the piping that requires, has the disadvantage that it is very time-consuming is there.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a pipe support device in which pipes can be easily attached and detached.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be described with reference to FIGS. 1 to 3 corresponding to the embodiments.
And forming a plurality of flow holes 3 at predetermined intervals in the supporting rod 1, these circulation holes 3, a plurality of pipes 2 ₁ ~n having a female thread portion 9 at one end a pipe such as a air cylinder in the piping support device comprising so as to connect the flange 5 externally threaded portion 5a is formed a central portion and one end portion through circulation holes 10 are provided, each pipe 2 ₁ - one end a male screw portion 5a of the flange 5 n of the flange 5
A structure in which the bolt 7 is fixed to the support rod 1 is adopted.

(Embodiment) FIG. 1 and FIG. 2 show a pipe supporting apparatus according to an embodiment of the present invention, for example, for a die driving air cylinder for a core in a casting core manufacturing apparatus. Etc.Piping 2 ₁
It is for collectively supporting ~ n. In these drawings, reference numeral 5 denotes a flange having an air passage hole 10 formed therethrough at the center thereof. The flange 5 has a male screw portion 5a formed at one end portion in the axial direction. 5b is integrally projected.

Thus, each pipe 2 ₁ ~n, to connect to each communication holes 3 of the supporting rod 1, as shown in FIG. 1, first, the pipes 2 ₁ one end a male screw portion 5a of the flange 5 ~n by screwing on one end internal thread portion 9 of integrally fixing each flange 5 on the pipes 2 ₁ ~n. The other end portion of the flange 5 fixed to the pipes 2 ₁ ~n way, is plunged into the communication holes 3 of the support rod 1 as in the second view, and both side projections 5b of the bolt 7 flange 5, from 5b By screwing each into the support rod 1,
Each flange 5 is fixed to the support rod 1. Thus, both sides of the pipe 2 ₁ ~n opposite to each other with respect to the support rod 1, 2 ₁ ~n is, as shown in FIG. 2, the flow holes 3 through channel 10 and supporting rod 1 of each flange 5 And are connected to each other via. still,
In FIG. 2, 8 is a seal ring interposed between each flange 5 and the support rod 1.

Further, To remove the respective pipes 2 ₁ ~n from the support rod 1, may be pulled off the bolts 7 of the flange 5 is screwed to the supporting rod 1.

According to the tube support device as described above, a male screw portion 5a formed at one end portion of the flange 5, screwed at one end internal thread portion 9 of the pipe 2 ₁ ~n, bolt 7 stop this flange 5 to support bars 1 simply, it is possible to mount easily the pipe 2 ₁ ~n. Moreover this case, each flange 5, like conventional nipple 4 shown in FIG. 4, adapted for attachment by screwing to an existing internal thread portion 9 which is provided at one end of the pipe 2 ₁ ~n because there, the pipe 2 ₁ is not necessary to perform a no threading the ~n, can be used as an existing pipe 2 ₁ ~n.

Piping support device (effect of invention and advantages) This invention is, a male screw portion 5a formed at one end of the flange 5, by screwing on one end internal thread portion 9 of the pipe 2 ₁ ~n, flange 5 each It is integrally fixed to the pipe 2 ₁ ~n. Then, by bolts 7 stop this flange 5 to support bars 1, each pipe 2 ₁ ~n is in a state communicating with the communication holes 3 of the supporting rod 1 via the communication holes 10 of each flange 5, supporting rod 1 is attached and supported. Also, by removing the bolt 7 of each flange 5, each pipe
It can be removed 2 ₁ ~n from the support rod 1.

Thus, according to the tube support system of the present invention, the flange 5 and the pipe 2 ₁ ~n is coupled by screwing the male screw portion 5a of the flange 5 side and pipe side of the female screw portion 9, and the flange 5 because There is bolted to the support rod 1, the mounting or detaching the pipe 2 ₁ ~n, without being able to be disturbed by the pipe 2 ₁ ~n adjacent, can be carried out quickly and easily.

Then, in particular according to the present invention, as the screw portion of the pipe-side screw portion of the flange 5 side is screwed, the internal thread portion 9 for a conventional nipple bond that is formed at one end portion of the pipe 2 ₁ ~n the availability as it is not necessary to perform a no threading into the pipes 2 ₁ ~n, using existing piping 2 ₁ ~n,
Since it can be attached to the support rod 1, it is extremely economically advantageous.
