[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a chassis structure for a cylindrical container such as a pressure vessel in which equipment is housed.

(Prior Art) Conventionally, in order to store equipment in a cylindrical container, equipment mounting portions are provided inside the cylindrical container and each device is fixed to these mounting portions, or as shown in the vertical cross-sectional view of Fig. 3. As shown in FIG.
2 and the cylindrical lids 23, 24, the fittings 26, 2 are fixed to the inner circumferential wall of the cylindrical body 22 of the cylindrical container 25.
6 with fixing screws 27, 27, device 2
1 was stored in a cylindrical container 25.

In addition, 28 is a power line from the outside of the cylindrical container 25,
This is a plug for connecting wiring such as signal lines.

(Problems to be solved by the invention) However, in the mounting structure shown in FIG. 3, one side of the device 21 is fixed to the mounting plate 20, so it is vulnerable to vibration, In addition, when a plurality of devices 21 are stored, wiring between each device and wiring from each device to the outside of the cylindrical container 25 is not easy.

The present invention was made to solve the above-mentioned conventional problems, and includes a fixed chassis with a box-shaped cross section inside a cylindrical container, and a movable chassis for attaching equipment that can be freely taken in and out of the fixed chassis. The purpose is to provide a chassis structure for a cylindrical container.

(Means for Solving the Problems) Means of the present invention for solving the above problems will be explained using FIGS. 1 and 2 corresponding to embodiments.

The present invention consists of a fixed chassis 6 with a box-shaped cross section fixed to the inner peripheral wall of the cylindrical body 1 of a cylindrical container 4 consisting of a cylindrical body 1 and container lids 2 and 3 via a plurality of fixtures 5; The movable chassis 7 for mounting equipment forms a monocot structure by attaching a plurality of equipment 8 that can be freely inserted into and removed from the inner circumferential wall of the fixed chassis 6 and fixed to the fixed chassis 6.

(Function) In the chassis structure of the cylindrical container configured as described above, the fixed chassis 6 having a box-shaped cross section is fixed inside the cylindrical body 1 of the cylindrical container 4, and a plurality of devices 8 are connected to the upper plate 7a and the lower plate 7b. A movable equipment mounting chassis 7, which forms a monocot structure by being clamped and fixed, is accommodated inscribed in the inner circumferential wall of the fixed chassis 6, and is fixed to the fixed chassis 6.

Therefore, the plurality of devices 8 to be housed in the cylindrical container 4 are integrated with the moving chassis 7 for device mounting and are supported by the entire fixed chassis 6, so that the vibration resistance is greatly improved and the plurality of devices 8 are It also improves storage efficiency.

(Example) Hereinafter, the present invention will be explained with reference to the drawings. 1 and 2 respectively show a longitudinal cross-sectional view and a cross-sectional view of an embodiment according to the present invention. A stationary chassis 6 having a box-shaped cross section is fixed via a fixture 5. In this embodiment, the fixed chassis 6
The upper plate and the lower plate are fixed to the upper and lower parts of the inner peripheral surface of the cylindrical body 1 with fixing screws 9, 9, respectively.
It is fixed by being screwed to the fixture 5.

Inside the fixed chassis 6, there is a movable chassis 7 for attaching equipment inscribed in the inner peripheral wall of the fixed chassis 6.
is accommodated.

This movable chassis 7 is connected to each device 8 (4 in the figure).
) is sandwiched between the upper plate 7a and the lower plate 7b, and the upper and lower parts of the device 8 are fixed with fixing screws 10 and 10, respectively. There is a stepped portion 7 on the upper plate 7a and the lower plate 7b.
They are formed with a monocot structure formed in a 〓-shape and 〓-shape, respectively, with c and 7c provided.

The stepped portions 7c, 7c of the upper plate 7a of the movable chassis 7 and the stepped portions 7c, 7c of the lower plate 7b are inscribed in the four corners of the inner peripheral surface of the fixed chassis 6, respectively. 7 is formed so that it can be freely inserted into and taken out from the fixed chassis 6.

In addition, the movable chassis 7 has its bottom plate 7d fixed to the bottom plate 6a of the fixed chassis 6 with guide pins 11, 11, and the open end of the fixed chassis 6 is fixed with fixing screws 13, 13 via a flange-shaped mounting plate 12. It is fixed to the part.

This mounting plate 12 is provided with a plug 14 for connecting wiring such as a power line and a signal line from the outside of the cylindrical container 4, and a terminal plate 15 for wiring connection.

In addition, 16 is the inner peripheral wall of the fixed chassis 6 and the equipment 8.
The space 17 and 18 is formed by the inner peripheral wall of the cylindrical body 1 and the outer peripheral wall of the fixed chassis 6, and is used as a space for wiring between each device 8. It is used as a space for wiring from the outside of the cylindrical container 4 to be connected to the connection plug 14 and the wiring connection terminal board 15.

In this way, the fixed chassis 6 is fixed to the cylindrical body 1, and the movable chassis 7 to which the devices 8, 8, 8, 8 are attached is housed and fixed within the fixed chassis 6 and supported by the entire fixed chassis 6. The vibration resistance is greatly improved, and since the stationary chassis 6 and the movable chassis 7 can be constructed of sheet metal, the overall weight of the chassis is reduced.

In addition, in the mobile chassis 7, each incorporated device 8 acts as a beam of the mobile chassis 7, so the feature of a monocottle structure is utilized, the rigidity of the mobile chassis 7 alone is improved, and a large number of devices 8
can be stored.

Furthermore, the wiring space 16 between each device 8 and the wiring spaces 17 and 18 from the outside of the cylindrical container 4 are separated, so that wiring from the outside can be hooked to the movable chassis 7 when loading and unloading the movable chassis 7. There is no need to worry about.

(Effects of the invention) As explained above, according to the invention, a movable chassis forming a monocot structure is housed and fixed by installing equipment in a fixed chassis with a box-shaped cross section fixed in a cylindrical container. Because of this, it has excellent vibration resistance, can store many devices even if it is a long cylindrical container, and also makes it easier to handle wiring between each device and from the outside of the cylindrical container to each device. There are advantages.
