Description

本発明は、貨物船のハッチカバーを開閉する装置の固定機構に関し、該固定機構は、その一端が船の船体に接続されており、他端がハッチカバー形成部材を移動する開閉装置に接続されている少なくとも一基の作動シリンダーを有している。開閉装置は扇形歯輪のような形状をしており、その歯の付いた周縁部がまた別の扇形歯輪と協働する。これによって、扇形歯輪のうちの１つが１つのハッチカバー形成部材に接続され、もう１つの扇形歯輪が近接するハッチカバー形成部材に接続され、前記作動シリンダーの操作によって両方のハッチカバー形成部材が動かされる。   The present invention relates to a fixing mechanism for a device that opens and closes a hatch cover of a cargo ship, the fixing mechanism having one end connected to the hull of the ship and the other end connected to an opening / closing device that moves a hatch cover forming member. At least one working cylinder. The switchgear is shaped like a fan-shaped tooth ring, and its peripheral edge cooperates with another fan-shaped tooth ring. Accordingly, one of the fan-shaped tooth rings is connected to one hatch cover forming member, and the other fan-shaped tooth ring is connected to an adjacent hatch cover forming member. By operating the operating cylinder, both hatch cover forming members are connected. Is moved.

従来の貨物船の開閉装置は、ハッチカバー形成部材を上昇させる扇形歯輪の動きが、扇形歯輪の両方又は１つに接続されている水圧シリンダーによって作動されるようになっていた。扇形歯輪をその低い位置（ハッチカバー形成部材の閉じた位置）に固定することは、別個の人手で挿入することのできる固定ピンによって行われる。扇形歯輪の代わりに別の種類の関節接続された機構も使用される。この別の機構における操作原理は、手動固定型の設計も含み、先に記載したものと等価である。   In a conventional cargo ship opening and closing device, the movement of the fan-shaped tooth ring that raises the hatch cover forming member is operated by a hydraulic cylinder connected to both or one of the fan-shaped tooth rings. Fixing the sector tooth ring in its lower position (closed position of the hatch cover forming member) is performed by a fixing pin that can be inserted manually. Another type of articulated mechanism is also used instead of a sector tooth ring. The operating principle of this alternative mechanism is equivalent to that described above, including a manually fixed design.

これら従来技術のシステムは、人手による別個の作業部分を必要とする扇形歯輪の固定技術によって制限を受けてきた。さらに、このような別工程としての固定は怠られる場合すらあり、結果として、荒波でハッチカバーが予期せずに開いてしまって耐候性のない積み荷に損害を与えてしまう危険性もある。最悪の場合、ハッチカバー形成部材が外れて船全体の安全性を損なう場合すら考えられる。さらにまた、開閉機構の部品（ピボットピン、扇形歯輪の接触面など）の摩滅によって原初的な操作による再調整が必要になることもある（例えば、ピボットピンを取り替え、扇形歯輪の面に溶接によって材料を加えてハッチカバー形成部材と接触するようにするなど）。   These prior art systems have been limited by fan ring fixation techniques that require a separate manual work piece. Furthermore, there is a case in which fixing as such a separate process may be neglected, and as a result, there is a risk that the hatch cover may open unexpectedly due to rough waves and damage the load that is not weather resistant. In the worst case, the hatch cover forming member may come off and even the safety of the entire ship is impaired. In addition, wear and tear of parts of the opening and closing mechanism (pivot pin, fan tooth ring contact surface, etc.) may require re-adjustment by primitive operation (for example, replacing the pivot pin so that the surface of the fan tooth ring is Such as welding to add material to the hatch cover forming member).

発明の詳細な説明Detailed Description of the Invention

本発明の目的は、ハッチカバーの固定と固定の解除とを、別の操作を必要とすることなく、自動で行うことのできるハッチカバー開閉装置用の固定機構を提供することである。本発明の目的は、作動シリンダーと扇形歯輪との間に三角板が配され、この三角板の１つの角部が作動シリンダーに軸支回転可能に接続され、第二の角部が扇形歯輪に軸支回転可能に接続され、第三の角部がレバー板に軸支回転可能に接続され、このレバー板は更に船体に搭載された蝶番のアイレットに軸支回転可能に接続されている固定機構であって、シリンダーが作動するとハッチカバー形成部材をその閉位置に固定することができ、シリンダーを反対方向に作動させることにより、それぞれのハッチカバー形成部材の固定を解除することができることを特徴とする本発明によって達成することができる。 An object of the present invention is to provide a fixing mechanism for a hatch cover opening / closing device that can automatically perform fixing and releasing of the hatch cover without requiring separate operations. An object of the present invention is to provide a triangular plate between the working cylinder and the fan- shaped tooth ring, one corner of the triangular plate is connected to the working cylinder so as to be pivotally supported, and the second corner is a fan-shaped tooth ring. A fixed mechanism that is pivotally connected, the third corner is pivotally connected to a lever plate, and this lever plate is further pivotally connected to a hinge eyelet mounted on the hull. When the cylinder is operated, the hatch cover forming member can be fixed in the closed position, and by operating the cylinder in the opposite direction, the fixing of each hatch cover forming member can be released. This can be achieved by the present invention.

本発明による固定機構の一態様は、固定機構の固定位置において、前記三角板と前記レバー板との間の回転支点が、三角板と前記歯車との間の回転支点と前記蝶番のアイレットと前記レバー板との間の回転支点とを結ぶ仮想線の下側の下死点と呼ばれる点に位置することによって特徴付けられる。別の態様においては、固定機構の固定位置において、前記三角板と前記レバー板との間の回転支点が、三角板と前記作動シリンダーとの間の回転支点と前記蝶番のアイレットと前記レバー板との間の回転支点とを結ぶ仮想線の上側に位置する。 One aspect of the fixing mechanism according to the present invention is that, at the fixing position of the fixing mechanism, the rotation fulcrum between the triangular plate and the lever plate is the rotation fulcrum between the triangular plate and the gear, the hinge eyelet, and the lever plate. It is characterized by being located at a point called the bottom dead center below the imaginary line connecting the rotation fulcrum between and. In another aspect, at the fixed position of the fixing mechanism, the rotation fulcrum between the triangular plate and the lever plate is between the rotation fulcrum between the triangular plate and the working cylinder, the eyelet of the hinge and the lever plate. It is located on the upper side of the imaginary line connecting the rotation fulcrum.

本発明のまた別の態様は、前記レバー板に留め具が形成、又は固定され、これに当接してレバー板に軸支回転可能に接続された前記三角板の端部が機構の固定位置に静止する。これによって、三角板とレバー板との間の回転支点が請求項２に定義された仮想線よりも下に落ちることを防いでいる。


 Another aspect of the present invention, fastener to said lever plate formed, or fixed, to which rest in a fixed position in contact with an end portion of the triangular plate which is axially supported rotatably connected to the lever plate a mechanism To do. This prevents the rotation fulcrum between the triangular plate and the lever plate from falling below the imaginary line defined in claim 2 .


したがって、本発明の利点は機能が完全に自動化されていることを含み、ハッチカバーの固定／固定解除は作業者によって怠られる可能性のある別の作業工程を必要としない。固定機構の蝶番のアイレットを垂直方向／水平方向に調整するのが容易であるので、その据え付け中に、ハッチカバー開閉装置の操作を微調整する複雑ではない方法を提供し、開閉装置部品の通常の摩滅を補償する。さらに、本発明による固定機構は、既に使用されている開閉装置に最小限の変更を加えるだけで後付けすることもできる。固定機構の構造は非常に単純で、操作における信頼性が高い。   Thus, the advantages of the present invention include that the function is fully automated, and the fixing / unlocking of the hatch cover does not require a separate work step that can be neglected by the operator. Since it is easy to adjust the hinge eyelet of the fixing mechanism in the vertical / horizontal direction, it provides a less complicated way to fine-tune the operation of the hatch cover opening / closing device during its installation, To compensate for the wear and tear. Furthermore, the fixing mechanism according to the invention can also be retrofitted with minimal changes to the already used switchgear. The structure of the fixing mechanism is very simple and reliable in operation.

以下において、添付の図面を参照しながら、好ましい例示的態様の助けを借りて、本発明をより詳細に記述する。   In the following, the invention will be described in more detail with the aid of preferred exemplary embodiments with reference to the accompanying drawings.

図１には、従来のハッチカバー開閉装置とその固定機構が示されている。ここでは、それぞれ一基の作動シリンダー２，２’が咬合する扇形歯輪１，１’の両方と接続されている。このように、扇形歯輪は該扇形歯輪に接続している作動シリンダーによって駆動される。しかしながら、この設計では、扇形歯輪をその下方位置（即ち、ハッチカバー形成部材が閉じた位置）に固定するのに別の固定ピン12が必要になる。このようにして、固定ピンは、ハッチカバー形成部材が海上で開くのを防いでいる。   FIG. 1 shows a conventional hatch cover opening / closing device and its fixing mechanism. Here, each of the working cylinders 2 and 2 'is connected to both of the fan-shaped tooth rings 1 and 1' engaged with each other. In this way, the sector tooth ring is driven by an actuating cylinder connected to the sector tooth ring. However, in this design, a separate fixing pin 12 is required to fix the sector tooth ring in its lower position (ie, the position where the hatch cover forming member is closed). In this way, the fixing pin prevents the hatch cover forming member from opening at sea.

図２には、扇形歯輪１と作動シリンダー２との間に、船体５に据え付けられた蝶番のアイレット６にレバー板４を介してさらに接続されている三角板３を追加した、本発明のハッチカバー開閉装置が示されている。このように、三角板３は３つの支持／回転支点７、８、１１を有している。これらの内、回転支点７は、三角板３と扇形歯輪１との間の回転支点であり、回転支点８は、三角板３とレバー板４との間の回転支点であり、回転支点１１は、三角板３と作動シリンダー２との間の回転支点である。レバー板４と蝶番のアイレット６との間の回転支点は参照符号９で示されている。   In FIG. 2, the hatch of the present invention, in which a triangular plate 3 further connected via a lever plate 4 to a hinge eyelet 6 installed on a hull 5 is added between the fan-shaped tooth ring 1 and the working cylinder 2. A cover opening and closing device is shown. Thus, the triangular plate 3 has three support / rotation fulcrums 7, 8, and 11. Among these, the rotation fulcrum 7 is a rotation fulcrum between the triangular plate 3 and the sector tooth ring 1, the rotation fulcrum 8 is a rotation fulcrum between the triangular plate 3 and the lever plate 4, and the rotation fulcrum 11 is This is a rotation fulcrum between the triangular plate 3 and the working cylinder 2. The rotational fulcrum between the lever plate 4 and the hinge eyelet 6 is indicated by reference numeral 9.

開閉装置及びその統合固定機構の機能は、回転支点の位置とシステム部品の幾何学とに基づいている。図２に示されている状態においては、ハッチカバー形成部材１３、１３’は相互に密着している。ここにおいて、作動シリンダー２は後方に引いた位置にある。次いで、三角板３とレバー板４との間の回転支点８を、三角板３と扇形歯輪１との間の回転支点７と蝶番のアイレット６とレバー板４との間の回転支点９とを結ぶ仮想線の下方、下死点と呼ばれる点に位置させることにより固定機能が実現される。同時に、固定機構の固定位置においては、三角板８とレバー板４との間の回転支点８は、三角板３と作動シリンダー２との間の回転支点１１と蝶番のアイレット６とレバー板４との間の回転支点９とを結ぶ仮想線の上に位置する。ハッチカバー形成部材１３、１３’を開くためには、作動シリンダーのピストンは回転支点７の周りに三角板を押し始め、このように回転支点８を押し上げてハッチカバー形成部材の固定を解除する。引き続いて、作動シリンダー２は、三角板３を介して扇形歯輪１を押して、ハッチカバー形成部材１３、１３’を開かせる（図２及び図３を見よ。）。ハッチカバーを閉じるのは逆の順番で行われる。   The function of the switchgear and its integrated fixing mechanism is based on the position of the rotation fulcrum and the geometry of the system components. In the state shown in FIG. 2, the hatch cover forming members 13, 13 'are in close contact with each other. Here, the working cylinder 2 is in a position pulled backward. Next, a rotation fulcrum 8 between the triangular plate 3 and the lever plate 4 is connected to a rotation fulcrum 7 between the triangular plate 3 and the fan tooth ring 1 and a rotation fulcrum 9 between the hinge eyelet 6 and the lever plate 4. The fixed function is realized by being positioned below the virtual line, at a point called bottom dead center. At the same time, in the fixed position of the fixing mechanism, the rotation fulcrum 8 between the triangular plate 8 and the lever plate 4 is between the rotation fulcrum 11 between the triangular plate 3 and the working cylinder 2, the hinge eyelet 6 and the lever plate 4. Is located on an imaginary line connecting the rotation fulcrum 9. In order to open the hatch cover forming members 13, 13 ′, the piston of the working cylinder starts to push the triangular plate around the rotation fulcrum 7, thus pushing up the rotation fulcrum 8 to release the hatch cover forming member. Subsequently, the working cylinder 2 pushes the fan-shaped tooth ring 1 through the triangular plate 3 to open the hatch cover forming members 13 and 13 ′ (see FIGS. 2 and 3). Closing the hatch cover is done in the reverse order.

レバー板４に設けられた留め具１０は、回転支点９と１１とを結ぶ仮想線の下方にある、先に下死点と呼んだ位置に回転支点８が達する位置に、三角板３が回転して入り込むのを防ぐ。   The fastener 10 provided on the lever plate 4 has the triangular plate 3 rotated at a position below the imaginary line connecting the rotation fulcrums 9 and 11 where the rotation fulcrum 8 reaches the position previously called the bottom dead center. To prevent intrusion.

蝶番のアイレット６の位置を作動シリンダーに近い方に動かすことにより、ハッチカバー開閉装置の摩滅によって生じる遊びを補償することができ、これによって、ハッチカバー形成部材の機能が容易に修正される。また、蝶番のアイレット６の調節が容易であるのでハッチカバー形成部材の据え付けを容易に行うことができ、蝶番のアイレット６を適切に配置することによって、他の不正確に搭載された部品が開閉装置の機能に与える効果を修正することが可能になる。蝶番のアイレット６は、回転支点９の位置のちょっとした変更をより容易にするために、様々なサイズの別個の搭載スペーサを備えることができる。   By moving the position of the hinge eyelet 6 closer to the working cylinder, it is possible to compensate for play caused by wear of the hatch cover opening and closing device, thereby easily correcting the function of the hatch cover forming member. In addition, since the adjustment of the hinge eyelet 6 is easy, the hatch cover forming member can be easily installed, and by properly arranging the hinge eyelet 6, other inaccurately mounted parts can be opened and closed. It is possible to modify the effect on the function of the device. The hinge eyelet 6 can be provided with separate mounting spacers of various sizes to make it easier to slightly change the position of the rotation fulcrum 9.

本発明が前記例示的態様に限定されず、添付の請求項の精神及び記載の範囲内で変えることができるのは、当業者には明らかである。したがって、ハッチカバー開閉装置の固定装置は、図面に示されているのとは異なるシステム幾何学及び構造を用いて実施することができる。回転支点の位置及び固定機構の相互ディメンジョンにも変更を加えることができる。   It will be apparent to those skilled in the art that the present invention is not limited to the foregoing exemplary embodiments, but can be varied within the spirit and scope of the appended claims. Therefore, the hatch cover opening and closing device securing device can be implemented using a different system geometry and structure than shown in the drawings. Changes can also be made in the position of the rotation fulcrum and the mutual dimensions of the locking mechanism.
