Description of the Related Art A space environment test apparatus that can open and close a door without attaching or detaching a refrigerant pipe is known (for example, see Patent Document 1).
JP 2003-137200 A

しかし、前記特許文献１に記載された接続構造では、開閉扉を直線的に移動させて真空容器本体を開閉する宇宙環境試験装置には、そのままでは適用できなかった。また、可撓性断熱配管を保持するステージの一部を扉側に固着し、残部を真空容器本体側に固着しているので、真空容器の大きさなどに応じて個別に設計、製作する必要があった。   However, the connection structure described in Patent Document 1 cannot be applied as it is to a space environment test apparatus that opens and closes the vacuum vessel body by moving the open / close door linearly. In addition, a part of the stage that holds the flexible heat insulating piping is fixed to the door side, and the remaining part is fixed to the vacuum vessel body side, so it is necessary to design and manufacture individually according to the size of the vacuum vessel. was there.

そこで本発明は、直線的に移動する開閉扉に適用でき、しかも、真空容器の大きさが異なっていても対応が可能で、開閉扉周辺の作業スペースも十分に確保することができる冷媒配管接続構造を備えた宇宙環境試験装置を提供することを目的としている。   Therefore, the present invention can be applied to a linearly moving opening / closing door, and can be applied even when the size of the vacuum vessel is different, and a refrigerant pipe connection that can sufficiently secure a working space around the opening / closing door. The object of the present invention is to provide a space environment test apparatus having a structure.

上記目的を達成するため、本発明の宇宙環境試験装置は、真空容器本体の内部に本体部シュラウドを、該真空容器本体に設けられた開閉扉の内部に扉部シュラウドをそれぞれ有し、前記扉部シュラウドを冷却するための液化窒素が流れる固定冷媒配管と、前記扉部シュラウドから扉の外側に引き出された扉部冷媒配管とを屈曲自在な可撓性断熱配管で接続した宇宙環境試験装置において、前記開閉扉を水平方向に設けられたガイドレールによって直線移動可能に支持し、前記可撓性断熱配管を開閉扉より上方位置で水平方向に配置したステージの上面に移動可能に載置するとともに、前記ステージを、宇宙環境試験装置を収納した収納体の天井部又は壁部から支持したことを特徴としている。   In order to achieve the above object, the space environment test apparatus of the present invention has a main body shroud inside a vacuum vessel main body, and a door shroud inside an open / close door provided in the vacuum vessel main body, In a space environment test apparatus, a fixed refrigerant pipe through which liquefied nitrogen for cooling a part shroud flows and a door part refrigerant pipe drawn out from the door shroud to the outside of the door are connected by a flexible heat insulating pipe. The open / close door is supported so as to be linearly movable by a guide rail provided in a horizontal direction, and the flexible heat insulating pipe is movably mounted on an upper surface of a stage disposed in a horizontal direction at a position above the open / close door. The stage is supported from a ceiling portion or a wall portion of a storage body in which a space environment test apparatus is stored.

さらに、本発明の宇宙環境試験装置は、前記可撓性断熱配管は、前記固定冷媒配管との接続部及び扉部冷媒配管との接続部から開閉扉の移動方向に向かって互いに平行に延設される一対の直線部と、反接続部側の直線部同士を繋ぐ円弧部とを有し、開閉扉の移動に伴って一方の直線部が短縮するとともに他方の直線部が伸張して円弧部が移動するように設けられていることを特徴としている。   Furthermore, in the space environment test apparatus according to the present invention, the flexible heat insulation pipe extends in parallel with each other in the moving direction of the opening / closing door from the connection part with the fixed refrigerant pipe and the connection part with the door refrigerant pipe. A pair of straight portions and a circular arc portion connecting the straight portions on the anti-connecting portion side, and with the movement of the opening and closing door, one straight portion is shortened and the other straight portion is expanded to be a circular arc portion. Is provided to move.

本発明の宇宙環境試験装置によれば、開閉扉を直線移動させて真空容器本体を開閉する宇宙環境試験装置においても、冷媒配管を着脱することなく開閉扉を開閉することができる。特に、可撓性断熱配管を支持するステージを宇宙環境試験装置の収納体、通常は宇宙環境試験装置を設置した建屋の天井部や壁部で支持することにより、ステージ下方の床部分を作業スペースとして使用することができる。また、ステージの支持部材を真空容器から切り離した状態としているので、開閉扉の移動距離が同程度ならば、真空容器の大きさに関係なく対応が可能である。   According to the space environment test apparatus of the present invention, even in a space environment test apparatus that opens and closes the vacuum vessel main body by linearly moving the opening and closing door, the opening and closing door can be opened and closed without attaching or detaching the refrigerant pipe. In particular, the stage supporting the flexible heat insulation piping is supported by the storage space of the space environment test equipment, usually the ceiling or wall of the building where the space environment test equipment is installed, so that the floor portion below the stage is a work space. Can be used as Further, since the stage support member is separated from the vacuum vessel, if the moving distance of the opening / closing door is approximately the same, it is possible to cope with the size regardless of the size of the vacuum vessel.

真空容器本体１２及び開閉扉１３の内部には、従来と同様の本体部シュラウド及び扉部シュラウド（いずれも図示省略）がそれぞれ設けられており、各シュラウドには、真空容器本体１２及び開閉扉１３の上部にそれぞれ突設したヘッドタンク１２ａ，１３ａを介して本体部冷媒供給管１６，本体部冷媒回収管１７，扉部冷媒供給管１８及び扉部冷媒回収管１９がそれぞれ接続されている。   Inside the vacuum vessel main body 12 and the open / close door 13, a main body portion shroud and a door portion shroud (both not shown) similar to the conventional one are provided, respectively, and the vacuum vessel main body 12 and the open / close door 13 are provided in each shroud. A main body refrigerant supply pipe 16, a main body refrigerant recovery pipe 17, a door refrigerant supply pipe 18 and a door refrigerant recovery pipe 19 are connected to each other through head tanks 12a and 13a projecting from the top of the main body.

また、宇宙環境試験装置を設置した建屋の床部からは、図示しない冷媒供給手段や冷媒回収手段に接続した主供給管２１及び主回収管２２が立ち上がっており、前記本体部冷媒供給管１６及び本体部冷媒回収管１７は、これらの主供給管２１及び主回収管２２からそれぞれ分岐し、建屋天井部からの吊り金具等によって固定されている。   A main supply pipe 21 and a main recovery pipe 22 connected to a refrigerant supply means and a refrigerant recovery means (not shown) rise from the floor of the building where the space environment test apparatus is installed, and the main body refrigerant supply pipe 16 and The main body refrigerant recovery pipe 17 is branched from each of the main supply pipe 21 and the main recovery pipe 22 and is fixed by a hanging metal fitting or the like from the building ceiling.

一方、前記扉部冷媒供給管１８及び扉部冷媒回収管１９と、前記主供給管２１及び主回収管２２からそれぞれ分岐した扉側固定供給管２３及び扉側固定回収管２４とは、ステージ２５に移動可能に載置された可撓性断熱配管２６，２７を介して接続されている。ステージ２５は、四方組みされた外枠２８の中に容器軸線に平行な方向の支持部材２９を複数本設けたものであって、梁３０等の建屋天井部部材や柱等の建屋壁部部材に取り付けた吊り金具３１により、開閉扉１３よりも上方位置で水平方向に支持されている。   On the other hand, the door part refrigerant supply pipe 18 and the door part refrigerant recovery pipe 19, and the door side fixed supply pipe 23 and the door side fixed recovery pipe 24 branched from the main supply pipe 21 and the main recovery pipe 22, respectively, are a stage 25. Are connected via flexible heat insulating pipes 26 and 27 mounted so as to be movable. The stage 25 is provided with a plurality of support members 29 in a direction parallel to the container axis in an outer frame 28 assembled in four directions, and a building ceiling member such as a beam 30 and a building wall member such as a column. Is supported in a horizontal direction at a position above the opening / closing door 13 by a hanging metal fitting 31 attached to the door.

扉部冷媒供給管１８及び扉部冷媒回収管１９と、扉側固定供給管２３及び扉側固定回収管２４とは、可撓性断熱配管２６，２７を円弧状に屈曲させたときの円弧の最小直径よりも大きな距離を隔ててステージ２５の一端側（開閉扉側）に設けられており、各管の可撓性断熱配管２６，２７との接続方向がステージ２５の他端方向（真空容器本体側）を向くように配置されている。   The door part refrigerant supply pipe 18 and the door part refrigerant recovery pipe 19, and the door side fixed supply pipe 23 and the door side fixed recovery pipe 24 are arc-shaped when the flexible heat insulating pipes 26 and 27 are bent in an arc shape. It is provided on one end side (opening / closing door side) of the stage 25 with a distance larger than the minimum diameter, and the connecting direction of each tube to the flexible heat-insulating piping 26, 27 is the other end direction of the stage 25 (vacuum container). It is arranged to face the main body side).

可撓性断熱配管２６，２７は、例えば、周知の真空断熱フレキシブルホースからなるものであって、扉部冷媒供給管１８及び扉部冷媒回収管１９との接続部１８ａ，１９ａ、扉側固定供給管２３及び扉側固定回収管２４との接続部２３ａ，２４ａから開閉扉１３の移動方向（容器軸線方向）に向かって互いに平行に延設される各一対の直線部２６ａ，２６ｂ，２７ａ，２７ｂと、反接続部側の直線部同士を繋ぐ半円形の円弧部２６ｃ，２７ｃとを有するＵ字状となっており、この円弧部２６ｃ，２７ｃが前記支持部材２９上にスライド可能に支持されている。   The flexible heat insulation pipes 26 and 27 are made of, for example, a well-known vacuum heat insulation flexible hose, and are connected to the door part refrigerant supply pipe 18 and the door part refrigerant recovery pipe 19, and door side fixed supply. A pair of linear portions 26a, 26b, 27a, 27b extending in parallel with each other in the moving direction (container axis direction) of the open / close door 13 from the connecting portions 23a, 24a with the pipe 23 and the door side fixed recovery pipe 24. And the semicircular arc portions 26c and 27c that connect the straight portions on the side opposite to the connection portion, and the arc portions 26c and 27c are slidably supported on the support member 29. Yes.

このような状態でステージ２５に載置された可撓性断熱配管２６，２７は、開閉扉１３の開閉の際に開閉扉１３と一緒に移動する扉部冷媒供給管１８及び扉部冷媒回収管１９の位置に応じて変形する。図１に実線で示すように、開閉扉１３が閉じているときには、扉部冷媒供給管１８及び扉部冷媒回収管１９がステージ２５の上部に進入し、扉部冷媒供給管１８及び扉部冷媒回収管１９側の直線部２６ａ，２７ａの長さは、扉側固定供給管２３及び扉側固定回収管２４側の直線部２６ｂ，２７ｂよりも短くなり、円弧部２６ｃ，２７ｃは、ステージ２５の真空容器本体側端部に位置した状態となっている。   In such a state, the flexible heat insulating pipes 26 and 27 placed on the stage 25 include a door part refrigerant supply pipe 18 and a door part refrigerant recovery pipe that move together with the door 13 when the door 13 is opened and closed. It deforms according to the position of 19. As shown by a solid line in FIG. 1, when the open / close door 13 is closed, the door refrigerant supply pipe 18 and the door refrigerant recovery pipe 19 enter the upper part of the stage 25, and the door refrigerant supply pipe 18 and the door refrigerant. The lengths of the straight portions 26 a and 27 a on the recovery tube 19 side are shorter than the straight portions 26 b and 27 b on the door side fixed supply tube 23 and the door side fixed recovery tube 24 side, and the arc portions 26 c and 27 c are formed on the stage 25. It is in the state located at the vacuum vessel body side end.

この状態から開閉扉１３を開いていくと、開閉扉１３と共に扉部冷媒供給管１８の接続部１８ａ及び扉部冷媒回収管１９の接続部１９ａが図３に示す位置へ移動する過程で、扉側固定供給管２３及び扉側固定回収管２４側の直線部２６ｂ，２７ｂが次第に短縮するとともに、扉部冷媒供給管１８及び扉部冷媒回収管１９側の直線部２６ａ，２７ａが次第に伸張し、円弧部２６ｃ，２７ｃは、ステージ２５の真空容器本体側から開閉扉側に向かって次第に移動する状態、すなわち、直線部２６ｂ，２７ｂの反接続部側が円弧部２６ｃ，２７ｃの一部となり、円弧部２６ｃ，２７ｃの直線部２６ａ，２７ａ側が直線部２６ａ，２７ａの反接続部側となるようにして、見掛け上、円弧部２６ｃ，２７ｃがステージ２５上を開閉扉１３の移動方向に向かって移動していく状態となる。開閉扉１３を閉じる際には、開閉扉１３の移動に伴って円弧部２６ｃ，２７ｃがステージ２５上を真空容器本体側に向かって逆方向に移動する状態となる。   When the open / close door 13 is opened from this state, the door 18 is connected to the door 18 in the process of moving the connecting portion 18a of the door portion refrigerant supply pipe 18 and the connecting portion 19a of the door portion refrigerant recovery pipe 19 to the position shown in FIG. The straight portions 26b and 27b on the side fixed supply tube 23 and the door side fixed recovery tube 24 side are gradually shortened, and the straight portions 26a and 27a on the door portion refrigerant supply tube 18 and door portion refrigerant recovery tube 19 side are gradually extended, The arc portions 26c and 27c gradually move from the vacuum vessel main body side of the stage 25 toward the open / close door side, that is, the opposite connection side of the linear portions 26b and 27b becomes a part of the arc portions 26c and 27c. The circular arc portions 26c and 27c are directed on the stage 25 in the moving direction of the open / close door 13 so that the straight portions 26a and 27a of 26c and 27c are opposite to the connecting portions of the straight portions 26a and 27a. A state that moves me. When closing the open / close door 13, the arc portions 26 c and 27 c move on the stage 25 in the opposite direction toward the vacuum vessel main body as the open / close door 13 moves.

したがって、可撓性断熱配管２６，２７の長さは、開閉扉１３を開閉する際の円弧部２６ｃ，２７ｃの移動量に応じて設定され、また、扉部冷媒供給管１８及び扉部冷媒回収管１９と、扉側固定供給管２３及び扉側固定回収管２４との距離は、可撓性断熱配管２６，２７の最小屈曲可能直径に応じた距離以上に設定される。   Therefore, the lengths of the flexible heat insulating pipes 26 and 27 are set according to the amount of movement of the arc portions 26c and 27c when the door 13 is opened and closed, and the door part refrigerant supply pipe 18 and the door part refrigerant recovery. The distance between the pipe 19 and the door-side fixed supply pipe 23 and the door-side fixed recovery pipe 24 is set to be equal to or greater than the distance corresponding to the minimum bendable diameter of the flexible heat insulating pipes 26 and 27.

このような冷媒配管接続構造を採用することにより、開閉扉１３の開閉の際に扉部冷媒供給管１８及び扉部冷媒回収管１９と扉側固定供給管２３及び扉側固定回収管２４とを着脱する必要がなくなり、開閉扉１３の開閉を容易に行うことができる。また、管接続時の漏洩試験や管取り外し時の昇温操作も不要となるので、開閉扉１３の開閉に要する作業を大幅に削減できるとともに、作業時間を大幅に短縮することができる。   By adopting such a refrigerant pipe connection structure, the door portion refrigerant supply pipe 18 and the door portion refrigerant recovery pipe 19, the door side fixed supply pipe 23 and the door side fixed recovery pipe 24 are connected when the open / close door 13 is opened and closed. It is not necessary to attach or detach, and the opening and closing door 13 can be easily opened and closed. Moreover, since a leak test at the time of pipe connection and a temperature raising operation at the time of pipe removal are not required, the work required to open and close the open / close door 13 can be greatly reduced, and the work time can be greatly shortened.

さらに、真空容器本体１２や開閉扉１３のヘッドタンク１２ａ，１３ａより上方にステージ２５を配置し、この宇宙環境試験装置を収納した建屋の天井部や壁部でステージ２５を支持したことにより、宇宙環境試験装置周辺の作業空間を十分に確保することができ、開閉扉１３の開閉や真空容器本体１２内の機器の搬入、搬出も容易に行うことが可能となる。   Furthermore, the stage 25 is arranged above the head tanks 12a and 13a of the vacuum vessel main body 12 and the open / close door 13, and the stage 25 is supported by the ceiling and the wall of the building that houses the space environment test apparatus. A sufficient working space around the environmental test apparatus can be ensured, and the opening / closing of the open / close door 13 and the loading / unloading of the equipment in the vacuum vessel main body 12 can be easily performed.

また、ステージ２５や可撓性断熱配管２６，２７等を円筒状真空容器１１から独立した状態で形成することができるので、径や長さ等の形状が異なる宇宙環境試験装置にも同じような配管構造を適用することができ、宇宙環境試験装置全体の製作コストを低減することが可能である。さらに、ステージ２５の上面部分で可撓性断熱配管２６，２７と接触する部分を低摩擦状態になるように加工したり、低摩擦材料、例えばフッ素樹脂板等で被覆したりすることにより、前述の円弧部２６ｃ，２７ｃの移動を円滑化することができる。   Further, since the stage 25, the flexible heat insulating pipes 26, 27, etc. can be formed in a state independent of the cylindrical vacuum vessel 11, the same applies to the space environment test apparatus having different shapes such as diameter and length. A piping structure can be applied, and the manufacturing cost of the entire space environment test apparatus can be reduced. Further, the portion of the upper surface portion of the stage 25 that contacts the flexible heat insulating pipes 26 and 27 is processed so as to be in a low friction state, or is covered with a low friction material such as a fluororesin plate. The movement of the arc portions 26c, 27c can be smoothed.

なお、各シュラウドの構造や形式は任意であり、特に限定されるものではない。また、ステージ２５は、水平とすることが望ましいが、ガス溜まりが生じない程度の僅かな傾斜があってもよい。さらに、ステージ２５の上面を平面板状とし、この平面板上を円滑に移動する部材によって可撓性断熱配管２６，２７を間接的にステージ２５で支持することも可能である。また、開閉扉１３の開閉方向は、容器軸線と直交する方向であってもよく、開閉扉１３を上吊り形式とすることも可能である。   In addition, the structure and form of each shroud are arbitrary and are not particularly limited. The stage 25 is preferably horizontal, but may have a slight inclination that does not cause gas accumulation. Further, the upper surface of the stage 25 may be a flat plate, and the flexible heat insulating pipes 26 and 27 may be indirectly supported by the stage 25 by a member that moves smoothly on the flat plate. In addition, the opening / closing direction of the opening / closing door 13 may be a direction orthogonal to the container axis, and the opening / closing door 13 may be suspended.
