It is also suitable for various vehicles such as cutter trucks. Further, the cabin 10 can be used not only for ships and airplanes but also for armored vehicles, tanks and the like, and is particularly useful for special vehicles used in nuclear facilities.

図1及び図2に示すように、キャビン10は、フロントボディ40、右サイドボディ50、左サイドボディ、ルーフボディ60、バックボディ80、ボトムボディ90で構成されたキャビンである。フロントボディ40には開口部が設けられこの開口部にフロントガラス20が取り付けられる。フロントガラス20の内側には、枠状の内側窓枠30が設けられ、内側窓枠30に放射線遮蔽ガラス11が取り付けられる。右サイドボディ50には3つの開口部が設けられ、一つの開口部にスライドドア51が取り付けられ、他の二つの開口部に、右サイドガラス22a、22cがそれぞれ取り付けられる。左サイドボディには、開口部が設けられ、この開口部に引き違いの窓ガラス(不図示)が取り付けられる。この引き違いの窓ガラスの前方窓ガラスの外側と後方窓ガラスの内側のそれぞれに放射線遮蔽ガラス(不図示)が透明な接着剤を用いて貼着される。スライドドア51に開口部が設けられこの開口部に右サイドガラス22bが取り付けられる。右サイドガラス22a、22b、22cの外側に放射線遮蔽ガラス21a、21b、21cが透明な接着剤を用いて貼着される。ルーフボディ60には開口部が設けられこの開口部にルーフガラス24が取り付けられ、ルーフガラス24の外側に放射線遮蔽ガラス23が透明な接着剤を用いて貼着される。放射線遮蔽ガラス11、21a~21c、23は、ガラスの主成分に酸化鉛を添加して製造されるガラスであり、鉛含有率が通常のガラスよりも高くなるように構成される。また、酸化鉛に加えて、酸化バリウムも添加するのも好適である。また、放射線遮蔽ガラス11の鉛当料は、2.0mmpb以上が好ましいが、2.0mmpbよりも小さい場合があってもよい。また、放射線遮蔽ガラス11は、鉛を含有しない場合、例えば、ストロンチウムやバリウムなどが含有される場合があってもよいし、これら以外のものが用いられる場合があってもよい。 As shown in FIGS. 1 and 2, the cabin 10 is a cabin composed of a front body 40, a right side body 50, a left side body, a roof body 60, a back body 80, and a bottom body 90. An opening is provided in the front body 40, and the windshield 20 is attached to the opening. A frame-shaped inner window frame 30 is provided inside the windshield 20, and the radiation shielding glass 11 is attached to the inner window frame 30. The right side body 50 is provided with three openings, a slide door 51 is attached to one opening, and the right side glasses 22a and 22c are attached to the other two openings, respectively. An opening is provided in the left side body, and a sliding window glass (not shown) is attached to this opening. Radiation shielding glass (not shown) is attached to the outside of the front window glass and the inside of the rear window glass of the sliding window glass using a transparent adhesive. An opening is provided in the slide door 51, and the right side glass 22b is attached to this opening. Radiation shielding glasses 21a, 21b, 21c are attached to the outside of the right side glasses 22a, 22b, 22c using a transparent adhesive. An opening is provided in the roof body 60, a roof glass 24 is attached to the opening, and a radiation shielding glass 23 is attached to the outside of the roof glass 24 using a transparent adhesive. The radiation shielding glasses 11, 21a to 21c, 23 are glasses manufactured by adding lead oxide to the main component of the glass, and are configured to have a higher lead content than ordinary glass. It is also preferable to add barium oxide in addition to lead oxide. The lead equivalent of the radiation shielding glass 11 is preferably 2.0 mmpb or more, but may be smaller than 2.0 mmpb. Further, when the radiation shielding glass 11 does not contain lead, for example, strontium, barium, or the like may be contained, or other than these may be used.

ボンネット41の裏側に放射線遮蔽ゴムシートの塗布加工を行う。また、図2に示すように、キャビン10の乗降口、右後ろ、及び後部(不図示)に放射線遮蔽カーテン100、150が設けられる。放射線遮蔽カーテン100、150は、複数枚の短冊状の放射線遮蔽ゴムシートを連結することで構成される。放射線遮蔽ゴムシートには、中性子遮蔽材やγ線遮蔽材の両方、またはいずれか一方が用いられる。中性子遮蔽材としては、樹脂にガドリニウムやホウ素やカドミウムを添加したものが好適であるがこれら以外の材料が添加される場合があってもよい。γ線遮蔽材としては、樹脂に鉛やタングステンやストロンチウムやバリウムを添加したものが好適であるがこれら以外の材料が添加される場合があってもよい。本実施形態では、放射線遮蔽ゴムシートとして樹脂に硫酸バリウムを配合したゴムシートが用いられる。また、放射線遮蔽ゴムシートの鉛当料は、0.39mmpb以上が好ましいが、0.39mmpbよりも小さい場合があってもよい。 A radiation shielding rubber sheet is applied to the back side of the bonnet 41. Further, as shown in FIG. 2, radiation shielding curtains 100 and 150 are provided at the entrance, the rear right, and the rear portion (not shown) of the cabin 10. The radiation shielding curtains 100 and 150 are configured by connecting a plurality of strip-shaped radiation shielding rubber sheets. For the radiation shielding rubber sheet, either a neutron shielding material or a γ-ray shielding material, or one of them is used. As the neutron shielding material, a resin to which gadolinium, boron or cadmium is added is preferable, but a material other than these may be added. As the γ-ray shielding material, a resin to which lead, tungsten, strontium, or barium is added is preferable, but a material other than these may be added. In the present embodiment, a rubber sheet in which barium sulfate is mixed with a resin is used as a radiation shielding rubber sheet. The lead equivalent of the radiation shielding rubber sheet is preferably 0.39 mmpb or more, but may be smaller than 0.39 mmpb.

図3は、放射線遮蔽カーテン100が開いた状態の正面図であり、図4は、放射線遮蔽カーテン100が閉じた状態の正面図である。放射線遮蔽カーテン100は、カーテンレール101、複数枚の短冊状の放射線遮蔽シート102、カーテンレール101のレールを移動可能な取付具120、放射線遮蔽シート102同士を連結させるヒンジ100~112で構成される。図3に示すように、ヒンジ100~112を配設することで、複数枚の放射線遮蔽シート102を蛇腹状にコンパクトに折りたたむことが可能となる。 FIG. 3 is a front view of the radiation shielding curtain 100 in an open state, and FIG. 4 is a front view of the radiation shielding curtain 100 in a closed state. The radiation shielding curtain 100 is composed of a curtain rail 101, a plurality of strip-shaped radiation shielding sheets 102, a fixture 120 capable of moving the rail of the curtain rail 101, and hinges 100 to 112 for connecting the radiation shielding sheets 102 to each other. .. As shown in FIG. 3, by disposing the hinges 100 to 112, it is possible to compactly fold a plurality of radiation shielding sheets 102 in a bellows shape.

このように、本実施形態によるキャビン10は、フロントガラス20の内側に放射線遮蔽ガラス11を貼着する構成であるため、ワイパー装置の改造が不要となる。また、放射線遮蔽ガラス11が外部に露出しないため、雨風によって放射線遮蔽ガラス11が破損したりする危険性も排除されるため、雨風時における乗物の作業性や安全性が確保される。 As described above, since the cabin 10 according to the present embodiment has a configuration in which the radiation shielding glass 11 is attached to the inside of the windshield 20, it is not necessary to modify the wiper device. Further, since the radiation shielding glass 11 is not exposed to the outside, the risk of the radiation shielding glass 11 being damaged by the rain and wind is eliminated, so that the workability and safety of the vehicle in the rain and wind are ensured.

また、本実施形態によるキャビン10は、フロントガラス以外のガラスにおいては、ガラスの外側に放射線遮蔽ガラスを接着剤で貼着する構成であるため、放射線遮蔽ガラスの取り付けコストを低くすることが可能であり、特に既存のキャビンを改造する上で有用である。なお、放射線遮蔽カーテンが取り付けられた位置にある右サイドガラス22b、22cの外側に放射線遮蔽ガラスを貼着しない場合があってもよい。 Further, since the cabin 10 according to the present embodiment has a structure in which the radiation shielding glass is attached to the outside of the glass other than the windshield with an adhesive, it is possible to reduce the mounting cost of the radiation shielding glass. Yes, especially useful for modifying existing cabins. In some cases, the radiation shielding glass may not be attached to the outside of the right side glasses 22b and 22c at the position where the radiation shielding curtain is attached.

また、本実施形態によるキャビン10は、乗降口等に放射線遮蔽カーテン100を設ける構成であるため、作業員の乗降がスムーズに行われることと作業員の作業時の被爆の低減が実現可能となる。また、放射線遮蔽カーテン100は容易に開閉可能な構成であるため、作業時における視認性の確保も容易に行うことが可能である。 Further, since the cabin 10 according to the present embodiment is configured to provide the radiation shielding curtain 100 at the entrance / exit, it is possible to smoothly get on / off the worker and reduce the exposure of the worker during the work. .. Further, since the radiation shielding curtain 100 has a structure that can be easily opened and closed, it is possible to easily secure visibility during work.

また、フロントガラス20や右サイドガラス22a~22cや左サイドガラス(不図示)やルーフガラス24や放射線遮蔽ガラス11、21a~21c、23に、放射線遮蔽ゴムをストライプ状に貼り付ける場合があってもよい。放射線遮蔽ゴムをストライプ状に配置することで、視認性を確保しつつも放射線の遮蔽性をさらに上げることが可能となる。 Further, the radiation shielding rubber may be attached in stripes to the windshield 20, the right side glasses 22a to 22c, the left side glass (not shown), the roof glass 24, and the radiation shielding glasses 11, 21a to 21c, 23. .. By arranging the radiation shielding rubber in a striped shape, it is possible to further improve the radiation shielding property while ensuring visibility.

上述の実施形態は、本発明の好適な一例であるので、技術的に好ましい種々の限定が付されているが、本発明の範囲は、上述の説明によって不当に限定されるものではない。また、上述の実施形態で説明される構成の全てが本発明の必須の構成要件ではない。また、上述の実施形態で説明される構成は相互に付け足したり組み合わせたりしてもよい。 Since the above-described embodiment is a preferred example of the present invention, various technically preferable limitations are added, but the scope of the present invention is not unreasonably limited by the above description. Moreover, not all of the configurations described in the above-described embodiments are essential constituent requirements of the present invention. Further, the configurations described in the above-described embodiments may be added to or combined with each other.

本発明は、乗物用のキャビンにおいて広く利用可能であり、特に、原子力関連施設において使用される特殊車両のキャビンにおいて広く利用可能である。 The present invention is widely available in vehicle cabins, especially in the cabins of special vehicles used in nuclear facilities.
