The solid line in the figure shows the state when the hatch cover 11 is closed. At this time, the opposing ends 12 of the hatch covers 11 are butted against each other. On the other hand, the phantom line a in the figure shows the state when the hatch cover 11 is opened. At this time, the opposing ends 12 of each hatch cover 11 are spaced apart from each other, and each hatch cover 11 is positioned at an open position X/2 away from the closed position.
　甲板９Ａ上には、各ハッチカバー対１１Ｐに対応した台座９Ｂが固定される。この台座９Ｂの前後端部には左右方向に延びるレール９Ｃが設けられる。ハッチカバー１１はこのレール９Ｃに案内されて左右方向に移動する。図１に示した船倉７の上部開口１０は、甲板９Ａと台座９Ｂを貫通して形成される。台座９Ｂは、ハッチカバー１１の前後幅より僅かに大きい前後幅を有する。 A pedestal 9B corresponding to each hatch cover pair 11P is fixed on the deck 9A. Rails 9C extending in the left-right direction are provided at the front and rear ends of the pedestal 9B. The hatch cover 11 is guided by the rail 9C and moves in the horizontal direction. The upper opening 10 of the hold 7 shown in FIG. 1 is formed through the deck 9A and the pedestal 9B. The base 9B has a front-to-rear width that is slightly larger than the front-to-rear width of the hatch cover 11 .
　図１０および図１１に本実施形態の船積み用雨除け装置２０を示す。なお、図１０では装置本体２０Ａを透過的に示す。船積み用雨除け装置２０は、前述の装置本体２０Ａと、装置本体２０Ａを昇降させると共に走行可能な昇降装置２０Ｂとを備える。図示例において、装置本体２０Ａと昇降装置２０Ｂは、閉じられた第１ハッチカバー対１１ＰＡの上に配置されている。 10 and 11 show a rain protection device 20 for shipping according to this embodiment. Note that FIG. 10 transparently shows the apparatus main body 20A. The rain protection device 20 for shipping includes the above-described device main body 20A, and an elevating device 20B capable of moving up and down the device main body 20A. In the illustrated example, the device main body 20A and the lifting device 20B are arranged on the closed first hatch cover pair 11PA.
　装置本体２０Ａは、一対のハッチカバー１１上に跨がって配置され、左側（一方）のハッチカバー１１上に配置された左側（一方）の端部１０１と、右側（他方）のハッチカバー１１上に配置された右側（他方）の端部１０２とを有する。 The apparatus main body 20A is arranged across a pair of hatch covers 11, and has a left (one) end portion 101 arranged on the left (one) hatch cover 11 and a right (other) hatch cover 11. and a right (other) end 102 positioned above.
　また装置本体２０Ａは、閉じたハッチカバー１１の近接端１２が位置するハッチ口１３の左右中心Ｃ１に対し、左側にオフセットして配置されている。右側端部１０２のレール１９は、右側ハッチカバー１１の近接端１２の近傍かつ右方に配置される。詳しくは後述するが、このレール１９の位置は、ハッチカバー１１が開いたときにレール１９が位置される位置である。 Further, the device main body 20A is offset to the left with respect to the left-right center C1 of the hatch opening 13 where the proximal end 12 of the closed hatch cover 11 is located. The rail 19 of the right end 102 is located near and to the right of the proximal end 12 of the right hatch cover 11 . Although details will be described later, the position of the rail 19 is the position where the rail 19 is positioned when the hatch cover 11 is opened.
　昇降装置２０Ｂは、ハッチカバー１１の開閉方向すなわち左右方向に走行可能である。複数（本実施形態では７つ）の昇降装置２０Ｂが、左側のハッチカバー１１上に、前後方向に所定間隔で配置され、装置本体２０Ａの左側端部１０１に連結されている。すなわち昇降装置２０Ｂは、左側のハッチカバー１１上にのみ配置され、装置本体２０Ａの左側端部１０１のみを昇降させる。 The lifting device 20B can travel in the opening/closing direction of the hatch cover 11, that is, in the left-right direction. A plurality of (seven in this embodiment) lifting devices 20B are arranged on the left hatch cover 11 at predetermined intervals in the front-rear direction, and are connected to the left end portion 101 of the device main body 20A. That is, the lifting device 20B is arranged only on the left hatch cover 11, and lifts and lowers only the left end portion 101 of the device main body 20A.
　７つの昇降装置２０Ｂのうち、３つが船上シュート２２の走行部３１に連結され、２つが前側の蓋部材２３に連結され、２つが後側の蓋部材２３に連結されている。また前後の蓋部材２３について、ハッチ口１３の前後方向（ハッチ口長手方向）の中心Ｃ２に近い方の１つの昇降装置２０Ｂが、蓋部材２３の蛇腹支持部７０に連結され、前後中心Ｃ２から遠い方の１つの昇降装置２０Ｂが、蓋部材２３のもう１つの蛇腹支持部７０に連結されている。 Of the seven lifting devices 20B, three are connected to the traveling portion 31 of the onboard chute 22, two are connected to the front lid member 23, and two are connected to the rear lid member 23. Regarding the front and rear lid members 23, one elevating device 20B closer to the center C2 in the longitudinal direction of the hatch opening 13 (longitudinal direction of the hatch opening) is connected to the bellows support portion 70 of the lid member 23 and lifts from the front and rear center C2. One remote lifting device 20B is connected to another bellows support 70 of the lid member 23 .
　このように複数の昇降装置２０Ｂで装置本体２０Ａの左側端部１０１を昇降させるので、昇降装置２０Ｂに付加される荷重を分散できる。また、昇降装置２０Ｂからハッチカバー１１に伝達される押し付け荷重も低減でき、ハッチカバー１１の損傷（凹み、傷付き等）を抑制できる。 Since the left end portion 101 of the device main body 20A is lifted and lowered by the plurality of lifting devices 20B, the load applied to the lifting devices 20B can be distributed. Also, the pressing load transmitted from the lifting device 20B to the hatch cover 11 can be reduced, and damage (dents, scratches, etc.) to the hatch cover 11 can be suppressed.
　図１２には、船上シュート２２の走行部３１に連結された昇降装置２０Ｂを示す。図示するように、昇降装置２０Ｂは走行用の車輪１０３を備える。車輪１０３はハッチカバー１１上に載置され、水平軸回りに回転可能であり、左右方向に走行可能である。 FIG. 12 shows the lifting device 20B connected to the travel portion 31 of the shipboard chute 22. As illustrated, the lifting device 20B includes wheels 103 for traveling. The wheels 103 are mounted on the hatch cover 11, are rotatable about a horizontal axis, and can travel in the left-right direction.
　また昇降装置２０Ｂは、装置本体２０Ａを昇降させるためのジャッキ１０４を備える。本実施形態のジャッキ１０４は油圧ジャッキである。しかしながらジャッキ１０４の種類は任意であり、例えばパンタグラフを有する機械式、電動式または空圧式であってもよい。 The lifting device 20B also includes a jack 104 for lifting the device body 20A. The jack 104 of this embodiment is a hydraulic jack. However, the type of jack 104 is arbitrary and may be, for example, mechanical with pantograph, electric or pneumatic.
　走行部３１に、左方（反ハッチ口側）に直線状に延びるブラケット１０５がボルト等により着脱可能に取り付けられる。昇降装置２０Ｂは、ブラケット１０５の先端部の下方の位置に配置される。ジャッキ１０４のピストンロッド１０６の先端部が、ピン１０７を介してブラケット１０５に回動可能に連結される。こうしてジャッキ１０４は、ブラケット１０５を介して走行部３１の上端部を持ち上げ、船上シュート２２ひいては装置本体２０Ａを持ち上げる。このとき固定キャスター３４が引っ掛かってレール１９が持ち上げられる。 A bracket 105 that extends linearly to the left (opposite side of the hatch) is detachably attached to the running portion 31 with a bolt or the like. The lifting device 20B is arranged below the tip of the bracket 105 . The tip of the piston rod 106 of the jack 104 is rotatably connected to the bracket 105 via the pin 107 . In this way, the jack 104 lifts the upper end of the traveling portion 31 via the bracket 105, and lifts the on-board chute 22 and the apparatus main body 20A. At this time, the fixed casters 34 are caught and the rail 19 is lifted.
　車輪１０３は、複数設けられ、本実施形態ではジャッキ１０４を挟んだ前後左右の位置に計４つ設けられる。これにより持ち上げ時における昇降装置２０Ｂの姿勢が安定し、昇降装置２０Ｂが転倒するのを抑制できる。なお車輪１０３の数および位置は任意であり、変更可能である。 A plurality of wheels 103 are provided, and in this embodiment, a total of four are provided at front, rear, left, and right positions with the jack 104 interposed therebetween. As a result, the posture of the lifting device 20B is stabilized during lifting, and the overturning of the lifting device 20B can be suppressed. Note that the number and positions of the wheels 103 are arbitrary and can be changed.
　昇降装置２０Ｂは、車輪１０３が設けられて走行可能な下側の走行部２０ＢＡと、ジャッキ１０４が設けられて上下方向に伸縮可能な上側の伸縮部２０ＢＢとを含む。本実施形態では、図中矢示するように、伸縮部２０ＢＢが走行部２０ＢＡに対し上下軸（もしくは縦軸）回りに回転可能に連結される。これによる利点は後述する。 The lifting device 20B includes a lower running section 20BA provided with wheels 103 and capable of traveling, and an upper extendable section 20BB provided with a jack 104 and capable of extending and contracting in the vertical direction. In this embodiment, as indicated by an arrow in the drawing, the extendable portion 20BB is connected to the traveling portion 20BA so as to be rotatable about the vertical axis (or the vertical axis). The advantages resulting from this will be described later.
　代替的に、昇降装置２０Ｂは図１３に示すような方法で装置本体２０Ａに連結されてもよい。この場合、レール１９を支持するシールホルダ８３に、左方（反ハッチ口側）にクランク状に延びるブラケット１０８が、ボルト等により着脱可能に取り付けられる。昇降装置２０Ｂは、ブラケット１０８の先端部の下方の位置に配置される。ジャッキ１０４のピストンロッド１０６の先端部が、ピン１０７を介してブラケット１０８に回動可能に連結される。こうしてジャッキ１０４は、ブラケット１０８を介してシールホルダ８３を持ち上げることにより、装置本体２０Ａを持ち上げる。なおブラケット１０８は、止水シート４１の下端を通過できるようクランク状に形成されている。ブラケット１０８は第１シール８０の穴に挿通され、その挿通箇所は別のシール材でシールされる。 Alternatively, the lifting device 20B may be connected to the device main body 20A in a manner as shown in FIG. In this case, a bracket 108 extending like a crank to the left (the side opposite to the hatch opening) is detachably attached to the seal holder 83 that supports the rail 19 with bolts or the like. The lifting device 20B is arranged below the tip of the bracket 108 . A tip portion of a piston rod 106 of the jack 104 is rotatably connected to a bracket 108 via a pin 107 . Thus, the jack 104 lifts the apparatus main body 20A by lifting the seal holder 83 via the bracket 108 . The bracket 108 is formed in a crank shape so that the lower end of the waterproof sheet 41 can be passed through. The bracket 108 is inserted through the hole of the first seal 80, and the inserted portion is sealed with another sealing material.
　次に、本実施形態の船積み用雨除け装置２０の使用方法を説明する。 Next, how to use the rain protection device 20 for shipping according to this embodiment will be described.
　図１０および図１４（Ａ）に示すように、本実施形態の船積み用雨除け装置２０は、ハッチカバー１１が閉状態にありハッチ口１３が閉じているときに設置可能であり、また実際に設置される。この点が特許文献１に記載の装置と相違し、本実施形態によれば安全性を著しく向上できる。 As shown in FIGS. 10 and 14(A), the rain shelter 20 for shipping according to the present embodiment can be installed when the hatch cover 11 is closed and the hatch opening 13 is closed. Installed. This point is different from the device described in Patent Document 1, and according to this embodiment, the safety can be significantly improved.
　設置の初期において、装置本体２０Ａは、前述したように、ハッチ口１３の左右中心Ｃ１に対し左側にオフセットした状態で左右のハッチカバー１１上に載置される。また複数の昇降装置２０Ｂは、左側のハッチカバー１１上に載置され、装置本体２０Ａの左側端部１０１に連結される。 At the initial stage of installation, the device main body 20A is placed on the left and right hatch covers 11 while being offset leftward from the left-right center C1 of the hatch opening 13, as described above. A plurality of lifting devices 20B are placed on the left hatch cover 11 and connected to the left end 101 of the apparatus main body 20A.
　次に、図１４（Ｂ）に示すように、昇降装置２０Ｂのジャッキ１０４が伸長される。これにより装置本体２０Ａの左側端部１０１が持ち上げられ、装置本体２０Ａが傾斜される。このとき、装置本体２０Ａの右側端部１０２は右側のハッチカバー１１上に接地したままである。よって装置本体２０Ａは、右側端部１０２の接地点を中心に左上がりになるよう傾動される。 Next, as shown in FIG. 14(B), the jack 104 of the lifting device 20B is extended. As a result, the left end portion 101 of the device main body 20A is lifted, and the device main body 20A is tilted. At this time, the right end portion 102 of the apparatus main body 20A remains grounded on the right hatch cover 11. As shown in FIG. Therefore, the device main body 20A is tilted upward to the left with the grounding point of the right end portion 102 as the center.
　次に、図１４（Ｃ）に示すように、左右のハッチカバー１１が開かれる。すると装置本体２０Ａの右側端部１０２は、右側のハッチカバー１１上に接地したまま、左右中心Ｃ１から離れるよう、右側にＸ／２だけ移動される。これにより装置本体２０Ａは、最初の位置から右側にＸ／２だけ移動される。 Next, as shown in FIG. 14(C), the left and right hatch covers 11 are opened. Then, the right end portion 102 of the apparatus main body 20A is moved rightward by X/2 so as to separate from the left-right center C1 while being grounded on the right hatch cover 11 . As a result, the device body 20A is moved rightward by X/2 from the initial position.
　一方、装置本体２０Ａの左側端部１０１は、昇降装置２０Ｂによって持ち上げられ左側のハッチカバー１１に接地していないため、左側のハッチカバー１１に追従しない。むしろ、左側のハッチカバー１１が左側に移動すると、昇降装置２０Ｂが左側のハッチカバー１１に対し相対的に右側に走行移動する（破線矢印参照）。よって装置本体２０Ａの左側端部１０１も、左側のハッチカバー１１に対し相対的に右側に相対移動する。 On the other hand, the left end 101 of the apparatus main body 20A is lifted by the lifting device 20B and does not touch the left hatch cover 11, so it does not follow the left hatch cover 11. Rather, when the left hatch cover 11 moves to the left, the lifting device 20B travels to the right relative to the left hatch cover 11 (see the dashed arrow). Accordingly, the left end portion 101 of the apparatus main body 20A also moves to the right relative to the left hatch cover 11 .
　こうして、左右のハッチカバー１１を支障なく開くことができ、ハッチカバー開放後に装置本体２０Ａを、左側および右側ハッチカバー１１上の所望の位置に位置させることができる。 Thus, the left and right hatch covers 11 can be opened without any trouble, and the device body 20A can be positioned at desired positions on the left and right hatch covers 11 after the hatch covers are opened.
　次に、図１４（Ｄ）に示すように、昇降装置２０Ｂのジャッキ１０４が収縮される。これにより装置本体２０Ａの左側端部１０１は左側ハッチカバー１１上に降ろされる。これにより船積み用雨除け装置２０の設置が実質的に完了し、荷役作業を行うことができる。 Next, as shown in FIG. 14(D), the jack 104 of the lifting device 20B is retracted. As a result, the left end portion 101 of the apparatus main body 20A is lowered onto the left hatch cover 11. As shown in FIG. This substantially completes the installation of the shipping rain protection device 20, and cargo handling work can be performed.
　本実施形態によれば、船積み用雨除け装置２０を設置した状態で、ハッチカバー１１を開閉することができる。よって利便性を大幅に高めることができる。 According to this embodiment, the hatch cover 11 can be opened and closed with the rain protection device 20 for shipping installed. Therefore, convenience can be greatly improved.
　特許文献１に記載の装置は基本的に、ハッチ口が開いているときにしか装置を設置できなかったので、ハッチ口から雨が浸入しないよう、晴天時に設置を行っていた。しかしこれだと、設置タイミングが晴天時に限定されてしまう。本実施形態では、晴天時は勿論のこと、雨天時にもハッチ口を閉じて装置を設置できる。そのため設置タイミングを増やすことができる。 The device described in Patent Document 1 basically could only be installed when the hatch opening was open, so it was installed during fine weather to prevent rain from entering through the hatch opening. However, in this case, the installation timing is limited to sunny weather. In this embodiment, the apparatus can be installed with the hatch opening closed not only in fine weather but also in rainy weather. Therefore, the installation timing can be increased.
　また、仮に特許文献１に記載の装置を、ハッチ口が閉じたときに設置した場合、降雨開始時に装置をシップローダで少し持ち上げ、ハッチ口を少しだけ開けて装置をハッチ口上に設置することが考えられる。しかしこれだと、シップローダが装置の移動に使われてしまうため、その間、シップローダを用いた荷役作業が行えない。本実施形態ではこうした事態も回避可能である。 In addition, if the device described in Patent Document 1 is installed when the hatch mouth is closed, it is possible to lift the device slightly by the ship loader when it starts raining, open the hatch mouth a little and install the device on the hatch mouth. Conceivable. However, in this case, the ship loader is used to move the equipment, so cargo handling work using the ship loader cannot be performed during that time. Such a situation can also be avoided in this embodiment.
　また本実施形態によれば、ハッチ口１３が閉じているときに船積み用雨除け装置２０を設置できる。そのため、設置作業中におけるハッチ口１３への落下を防止でき、安全性を著しく向上することができる。 Also, according to this embodiment, the rain protection device 20 for shipping can be installed when the hatch opening 13 is closed. Therefore, it is possible to prevent it from falling into the hatch opening 13 during the installation work, thereby significantly improving safety.
　本実施形態では、昇降装置２０Ｂの伸縮部２０ＢＢが、走行部２０ＢＡに対し上下軸回りに回転可能に連結されている。そのため、伸縮部２０ＢＢに対する走行部２０ＢＡの回転方向の向きを変え、昇降装置２０Ｂをハッチカバー開閉方向以外の方向に走行させることもできる。例えば、蛇腹部６９を伸縮させるとき、昇降装置２０Ｂにより装置本体２０Ａの左側の端部１０１を持ち上げると共に、走行部２０ＢＡをその蛇腹部６９の伸縮方向に走行させて伸縮を補助することができる。 In this embodiment, the expansion/contraction part 20BB of the lifting device 20B is connected to the travel part 20BA so as to be rotatable around the vertical axis. Therefore, it is possible to change the rotation direction of the travel portion 20BA with respect to the expandable portion 20BB, and to travel the lifting device 20B in a direction other than the hatch cover opening/closing direction. For example, when expanding and contracting the bellows portion 69, the lifting device 20B lifts the left end portion 101 of the apparatus main body 20A, and the traveling portion 20BA is caused to travel in the expansion and contraction direction of the bellows portion 69 to assist the expansion and contraction.
　なお、装置本体２０Ａと昇降装置２０Ｂの初期設置位置を、図１０に示したものと逆にしてもよい。すなわち、装置本体２０Ａを左右中心Ｃ１に対し右側にオフセットして配置し、昇降装置２０Ｂを右側のハッチカバー１１上に配置し、装置本体２０Ａの右側端部１０２に連結してもよい。 Note that the initial installation positions of the device main body 20A and the lifting device 20B may be reversed from those shown in FIG. That is, the device main body 20A may be offset to the right with respect to the horizontal center C1, and the lifting device 20B may be provided on the right hatch cover 11 and connected to the right end portion 102 of the device main body 20A.
　次に、本実施形態の変形例を説明する。 Next, a modified example of this embodiment will be described.
　図１５に示すように、本変形例の船積み用雨除け装置２０は、装置本体２０Ａの右側端部１０２に連結された昇降装置２０Ｂも備えている。この右側の昇降装置２０Ｂは、右側のハッチカバー１１上に配置される。 As shown in FIG. 15, the shipping rain protection device 20 of this modification also includes a lifting device 20B connected to the right end portion 102 of the device main body 20A. The right lifting device 20B is arranged on the right hatch cover 11 .
　本変形例の場合、装置本体２０Ａは、閉じたハッチカバー１１上に最初に設置されるものの、ハッチ口１３の左右中心Ｃ１に対しオフセットされておらず、その左右中心Ｃ１と同じ左右位置に配置されている。 In the case of this modification, the device main body 20A is first installed on the closed hatch cover 11, but is not offset with respect to the left-right center C1 of the hatch opening 13, and is arranged at the same left-right position as the left-right center C1. It is
　左側昇降装置２０Ｂと同数（７つ）の右側昇降装置２０Ｂが、左側昇降装置２０Ｂと同じ前後方向の位置に左右対称に配置されている。但しこれらの数および位置は変えてもよい。こうして昇降装置２０Ｂは、左側および右側の両方のハッチカバー１１上に配置され、装置本体２０Ａの左側端部１０１および右側端部１０２を昇降させる。 The same number (seven) of right elevating devices 20B as the left elevating devices 20B are arranged symmetrically at the same longitudinal position as the left elevating devices 20B. However, these numbers and positions may be changed. Thus, the lifting device 20B is arranged on both the left and right hatch covers 11 and lifts the left end 101 and the right end 102 of the device main body 20A.
　本変形例によれば、より多くの昇降装置２０Ｂで装置本体２０Ａを昇降させるので、昇降装置２０Ｂに付加される荷重をさらに分散できる。また、昇降装置２０Ｂからハッチカバー１１に伝達される押し付け荷重もさらに低減でき、ハッチカバー１１の損傷（凹み、傷付き等）を一層抑制できる。 According to this modified example, the device body 20A is raised and lowered by more lifting devices 20B, so the load applied to the lifting devices 20B can be further dispersed. In addition, the pressing load transmitted from the lifting device 20B to the hatch cover 11 can be further reduced, and damage (dents, scratches, etc.) to the hatch cover 11 can be further suppressed.
　本変形例の船積み用雨除け装置２０の使用方法は大略同様である。図１６（Ａ）に示すように、まず装置本体２０Ａが、閉じている左右のハッチカバー１１上に、かつ、ハッチ口１３の左右中心Ｃ１と同じ左右位置に配置される。また複数の昇降装置２０Ｂが、左側および右側のハッチカバー１１上に載置され、装置本体２０Ａの左側端部１０１および右側端部１０２に連結される。 The method of using the rain protection device 20 for shipping of this modified example is roughly the same. As shown in FIG. 16A, first, the device main body 20A is placed on the closed left and right hatch covers 11 and at the same horizontal position as the left and right center C1 of the hatch opening 13 . A plurality of lifting devices 20B are mounted on the left and right hatch covers 11 and connected to the left end 101 and right end 102 of the device body 20A.
　次に、図１６（Ｂ）に示すように、左側および右側の昇降装置２０Ｂのジャッキ１０４が伸長される。これにより装置本体２０Ａの全体が水平のまま持ち上げられる。 Next, as shown in FIG. 16(B), the jacks 104 of the left and right lifting devices 20B are extended. As a result, the entire device body 20A is lifted horizontally.
　次に、図１６（Ｃ）に示すように、左右のハッチカバー１１が開かれる。このとき装置本体２０Ａがハッチカバー１１に追従しないよう、装置本体２０Ａが図示しない固定部材により船舶（例えば甲板９Ａ）に固定される。これにより、装置本体２０Ａが一定位置に保持されたまま、左側の昇降装置２０Ｂは左側のハッチカバー１１に対し相対的に右側に走行移動し、右側の昇降装置２０Ｂは右側のハッチカバー１１に対し相対的に左側に走行移動する（破線矢印参照）。 Next, as shown in FIG. 16(C), the left and right hatch covers 11 are opened. At this time, the device main body 20A is fixed to the ship (for example, the deck 9A) by a fixing member (not shown) so that the device main body 20A does not follow the hatch cover 11 . As a result, the left lifting device 20B travels to the right relative to the left hatch cover 11 while the device main body 20A is held at a fixed position, and the right lifting device 20B moves relative to the right hatch cover 11. It moves relatively to the left (see dashed arrow).
　こうして、左右のハッチカバー１１を支障なく開くことができ、ハッチカバー開放後に装置本体２０Ａを、左側および右側ハッチカバー１１上の所望の位置に位置させることができる。 Thus, the left and right hatch covers 11 can be opened without any trouble, and the device body 20A can be positioned at desired positions on the left and right hatch covers 11 after the hatch covers are opened.
　次に、図１６（Ｄ）に示すように、昇降装置２０Ｂのジャッキ１０４が収縮される。これにより装置本体２０Ａの左側端部１０１および右側端部１０２が左側および右側ハッチカバー１１上に降ろされる。これにより船積み用雨除け装置２０の設置が実質的に完了し、荷役作業を行うことができる。 Next, as shown in FIG. 16(D), the jack 104 of the lifting device 20B is retracted. As a result, the left end portion 101 and the right end portion 102 of the apparatus main body 20A are lowered onto the left and right hatch covers 11 . This substantially completes the installation of the shipping rain protection device 20, and cargo handling work can be performed.
　なお、本変形例の場合、装置本体２０Ａは図１５に示した位置に初期設置されなくてもよい。閉じたハッチカバー１１上の別の位置に初期設置し、その後、ハッチカバー１１の開放直前で、昇降装置２０Ｂにより、装置本体２０Ａを持ち上げて図１５に示した位置に移動してもよい。伸縮部２０ＢＢに対する走行部２０ＢＡの向きを変えられるため、装置本体２０Ａを持ち上げて移動するときの移動方向は任意である。 In addition, in the case of this modification, the device main body 20A does not have to be initially installed at the position shown in FIG. It may be initially installed at another position on the closed hatch cover 11, and then just before the hatch cover 11 is opened, the apparatus main body 20A is lifted by the lifting device 20B and moved to the position shown in FIG. Since the orientation of the traveling portion 20BA with respect to the expandable portion 20BB can be changed, the direction of movement when the device main body 20A is lifted and moved is arbitrary.
　［第２実施形態］
　次に、本開示の第２実施形態を説明する。なお前記第１実施形態と同様の部分については図中同一符号を付して説明を割愛し、以下、第１実施形態との相違点を主に説明する。 [Second embodiment]
Next, a second embodiment of the present disclosure will be described. The same parts as those of the first embodiment are denoted by the same reference numerals in the drawings, and the description thereof is omitted. The following mainly describes the differences from the first embodiment.
　図１７および図１８に第２実施形態の船積み用雨除け装置２０を示す。なお図１７では装置本体２０Ａを透過的に示す。船積み用雨除け装置２０は、前記同様、装置本体２０Ａと、昇降装置２０Ｂとを備える。 17 and 18 show a rain protection device 20 for shipping according to the second embodiment. Note that FIG. 17 transparently shows the apparatus main body 20A. The shipping rain protection device 20 includes a device main body 20A and an elevating device 20B in the same manner as described above.
　ここで、ハッチカバー１１の開閉方向（左右方向）に直角な方向（前後方向）をカバー幅方向ともいう。ハッチカバー１１は、カバー幅方向における一方の端部すなわち前側端部１１１と、他方の端部すなわち後側端部１１２とを有する。 Here, the direction (front-rear direction) perpendicular to the opening/closing direction (left-right direction) of the hatch cover 11 is also referred to as the cover width direction. The hatch cover 11 has one end in the cover width direction, that is, a front end 111 and the other end, that is, a rear end 112 .
　昇降装置２０Ｂは、ハッチカバー１１上ではなく、ハッチカバー１１の前側端部１１１と後側端部１１２の前後方向における外側に配置されている。具体的には昇降装置２０Ｂは、ハッチカバー１１の前側端部１１１と後側端部１１２の外側で、かつ、台座９Ｂ近傍の位置において、甲板９Ａ上に配置されている。 The lifting device 20B is arranged not on the hatch cover 11 but outside the front end 111 and the rear end 112 of the hatch cover 11 in the front-rear direction. Specifically, the lifting device 20B is arranged on the deck 9A outside the front end 111 and the rear end 112 of the hatch cover 11 and near the pedestal 9B.
　前側の昇降装置２０Ｂは、前側ブラケット１１３を介して装置本体２０Ａの前側端部１１４に連結されている。具体的には、前側ブラケット１１３は左右方向に延び、その左端が左側レール１９（またはシールホルダ８３、以下同様）の前端に連結され、その右端が右側レール１９の前端に連結されている。前側ブラケット１１３は、左側レール１９および右側レール１９に、ボルト等により着脱可能に取り付けられる。そして前側ブラケット１１３の長手方向の中間部の下方に、前側の昇降装置２０Ｂが配置され、昇降装置２０Ｂが前記同様の方法で前側ブラケット１１３に接続される。こうして１つの昇降装置２０Ｂにより装置本体２０Ａの前側端部１１４が持ち上げられる。 The front lifting device 20B is connected to the front end portion 114 of the device main body 20A via the front bracket 113 .

The front bracket 113 is detachably attached to the left rail 19 and the right rail 19 with bolts or the like. The front elevating device 20B is arranged below the middle portion in the longitudinal direction of the front bracket 113, and the elevating device 20B is connected to the front bracket 113 in the same manner as described above. In this way, the front end portion 114 of the device main body 20A is lifted by one lifting device 20B.
　後側の昇降装置２０Ｂについては、前側の昇降装置２０Ｂと前後対称であるから説明を省略する。符号１１５は後側ブラケットを示し、符号１１６は装置本体２０Ａの後側端部を示す。図１９には、前側および後側の昇降装置２０Ｂにより装置本体２０Ａが水平に持ち上げられている様子を示す。 The rear elevation device 20B is symmetrical with the front elevation device 20B, so the explanation is omitted. Reference numeral 115 indicates a rear bracket, and reference numeral 116 indicates a rear end portion of the device main body 20A. FIG. 19 shows a state in which the apparatus body 20A is horizontally lifted by the front and rear elevating devices 20B.
　本実施形態の場合、装置本体２０Ａは、閉じたハッチカバー１１上に最初に設置されるものの、ハッチ口１３の左右中心Ｃ１に対しオフセットされておらず、その左右中心Ｃ１と同じ左右位置に配置されている。 In the case of this embodiment, although the device main body 20A is first installed on the closed hatch cover 11, it is not offset with respect to the left-right center C1 of the hatch opening 13, and is arranged at the same left-right position as the left-right center C1. It is
　昇降装置２０Ｂは前記同様であり、ハッチカバー１１の開閉方向すなわち左右方向に走行可能である。 The lifting device 20B is the same as described above, and can travel in the opening/closing direction of the hatch cover 11, that is, in the left-right direction.
　次に、本実施形態の船積み用雨除け装置２０の使用方法を説明する。 Next, how to use the rain protection device 20 for shipping according to this embodiment will be described.
　図２０に示すように、まず装置本体２０Ａが、第１ハッチカバー対１１ＰＡの閉じたハッチカバー１１上に、かつ、ハッチ口１３の左右中心Ｃ１と同じ左右位置に配置される。また前側および後側の昇降装置２０Ｂが、甲板９Ａ上に載置され、装置本体２０Ａの前側端部１１４および後側端部１１６に連結される。 As shown in FIG. 20, the apparatus main body 20A is first placed on the closed hatch cover 11 of the first hatch cover pair 11PA and at the same lateral position as the lateral center C1 of the hatch opening 13. Front and rear lifting devices 20B are also mounted on deck 9A and connected to front end 114 and rear end 116 of device body 20A.
　次に、図１９に示したように、前側および後側の昇降装置２０Ｂのジャッキ１０４が伸長される。これにより装置本体２０Ａの全体は水平のまま持ち上げられる。 Next, as shown in FIG. 19, the jacks 104 of the front and rear lifting devices 20B are extended. As a result, the entire apparatus body 20A is lifted horizontally.
　次に、図２１に示すように、左右のハッチカバー１１が開かれる。このとき装置本体２０Ａが昇降装置２０Ｂによって持ち上げられているので、ハッチカバー１１の開動作が阻害されない。こうして、左右のハッチカバー１１を支障なく開くことができる。 Next, as shown in Fig. 21, the left and right hatch covers 11 are opened. At this time, since the device main body 20A is lifted by the lifting device 20B, the opening operation of the hatch cover 11 is not hindered. In this way, the left and right hatch covers 11 can be opened without any trouble.
　次に、図１８に示したように、昇降装置２０Ｂのジャッキ１０４が収縮される。これにより装置本体２０Ａが左側および右側ハッチカバー１１上に降ろされる。これにより船積み用雨除け装置２０の設置が実質的に完了し、荷役作業を行うことができる。 Next, as shown in FIG. 18, the jack 104 of the lifting device 20B is retracted. As a result, the device main body 20A is lowered onto the left and right hatch covers 11. As shown in FIG. This substantially completes the installation of the shipping rain protection device 20, and cargo handling work can be performed.
　次に、荷役作業終了後、図１９に示すように、装置本体２０Ａが昇降装置２０Ｂにより持ち上げられ、左右のハッチカバー１１が閉じられる。 Next, after the cargo handling work is finished, as shown in FIG. 19, the device main body 20A is lifted by the lifting device 20B, and the left and right hatch covers 11 are closed.
　次いで、図２２に示すように、前側および後側の昇降装置２０Ｂは、装置本体２０Ａを持ち上げたまま走行移動し、装置本体２０Ａを、閉じた状態の第２ハッチカバー対１１ＰＢ上に移送する。 Next, as shown in FIG. 22, the front and rear lifting devices 20B travel while lifting the device main body 20A, and transfer the device main body 20A onto the closed second hatch cover pair 11PB.
　このとき、前後の昇降装置２０Ｂは、装置本体２０Ａを持ち上げたまま、まず左側に走行移動し、装置本体２０Ａを、第１ハッチカバー対１１ＰＡの台座９Ｂの外側（左側）に移動する。そして前後の昇降装置２０Ｂの走行部２０ＢＡの向きが９０°変えられる。これにより前後の昇降装置２０Ｂは前後方向に移動可能となる。次いで前後の昇降装置２０Ｂは、甲板９Ａ上を後方に走行移動し、装置本体２０Ａを、第２ハッチカバー対１１ＰＢの台座９Ｂの左側に移動する。その後、前後の昇降装置２０Ｂの走行部２０ＢＡの向きが再び９０°変えられ、前後の昇降装置２０Ｂが左右方向に移動可能とされる。次いで前後の昇降装置２０Ｂは、右方に走行移動し、装置本体２０Ａを、第２ハッチカバー対１１ＰＢ上に移動する。 At this time, the front and rear lifting devices 20B first travel to the left while lifting the device main body 20A, and move the device main body 20A to the outside (left side) of the pedestal 9B of the first hatch cover pair 11PA. Then, the orientation of the running portions 20BA of the front and rear lifting devices 20B is changed by 90°. As a result, the front and rear lifting devices 20B can move in the front-rear direction. Next, the front and rear lifting devices 20B travel rearward on the deck 9A, moving the device main body 20A to the left side of the pedestal 9B of the second hatch cover pair 11PB. After that, the orientation of the running portions 20BA of the front and rear lifting devices 20B is again changed by 90°, and the front and rear lifting devices 20B are made movable in the left-right direction. Next, the front and rear lifting devices 20B travel rightward to move the device main body 20A onto the second hatch cover pair 11PB.
　次に、図２３に示すように、第２ハッチカバー対１１ＰＢの左右のハッチカバー１１が開かれる。このときにもハッチカバー１１を支障なく開くことができる。 Next, as shown in FIG. 23, the left and right hatch covers 11 of the second hatch cover pair 11PB are opened. Also at this time, the hatch cover 11 can be opened without any trouble.
　次に、図１８に示すように、昇降装置２０Ｂのジャッキ１０４が収縮される。これにより装置本体２０Ａがハッチカバー１１上に降ろされ、船積み用雨除け装置２０の設置が実質的に完了し、荷役作業を行うことができる。 Next, as shown in FIG. 18, the jack 104 of the lifting device 20B is retracted. As a result, the device main body 20A is lowered onto the hatch cover 11, the installation of the rain protection device 20 for shipping is substantially completed, and cargo handling work can be performed.
　本実施形態は、第１実施形態の利点に加え、次の利点を有する。すなわち、昇降装置２０Ｂを走行させることで装置本体２０Ａをハッチカバー対１１Ｐ間で移動させることができ、複数のハッチカバー対１１Ｐに対し装置本体２０Ａを共用できる。よって、装置コストを低減することができる。 This embodiment has the following advantages in addition to the advantages of the first embodiment. That is, the device main body 20A can be moved between the hatch cover pairs 11P by running the lifting device 20B, and the device main body 20A can be shared by a plurality of hatch cover pairs 11P. Therefore, device cost can be reduced.
　装置本体２０Ａは、シップローダ１を使ってハッチカバー対１１Ｐ間で移動させることもできる。しかしこうすると、移動の間、シップローダ１による荷役作業が行えなくなり、作業効率が低下する。本実施形態によれば、こうした作業効率低下を回避することができる。 The device main body 20A can also be moved between the hatch cover pair 11P using the ship loader 1. However, if this is done, cargo handling work cannot be performed by the ship loader 1 during movement, and work efficiency is reduced. According to this embodiment, it is possible to avoid such a decrease in work efficiency.
　また本実施形態によれば、ハッチカバー対１１Ｐ上の位置と、それ以外の位置との間で、装置本体２０Ａを移動することもできる。例えば、ハッチカバー対１１Ｐ以外の甲板９Ａ上の位置で装置本体２０Ａを初期設置し、装置本体２０Ａを使用する際に装置本体２０Ａをハッチカバー対１１Ｐ上に移動することができる。 Further, according to this embodiment, the apparatus main body 20A can be moved between the position above the hatch cover pair 11P and other positions. For example, the apparatus main body 20A can be initially installed at a position on the deck 9A other than the hatch cover pair 11P, and the apparatus main body 20A can be moved onto the hatch cover pair 11P when using the apparatus main body 20A.
　また例えば、晴天時等で装置本体２０Ａが必要ない場合には、装置本体２０Ａをハッチカバー対１１Ｐ上以外の別の場所に退避させることも可能である。 Also, for example, when the device main body 20A is not needed due to fine weather, etc., it is possible to retract the device main body 20A to another location other than on the hatch cover pair 11P.
　このように本実施形態によれば、装置本体２０Ａを船上で比較的自由に移動できるため、利便性を高めることができる。 As described above, according to the present embodiment, the device main body 20A can be moved relatively freely on the ship, so convenience can be improved.
　なお、ここでは第１ハッチカバー対１１ＰＡからその隣の第２ハッチカバー対１１ＰＢに装置本体２０Ａを移動させる例を説明したが、より離れたハッチカバー対１１Ｐ間で装置本体２０Ａを移動させてもよい。 Here, an example of moving the device main body 20A from the first hatch cover pair 11PA to the adjacent second hatch cover pair 11PB has been described, but the device main body 20A may be moved between the hatch cover pairs 11P further apart. good.
