Description

本発明は、水圧作用力と重力を原動力として自動開閉作動を行う浮体式起伏ゲート設備において、扉体を強制的に起立・倒伏作動させることが可能な浮体式起伏ゲートの扉体起立・倒伏作動装置に関する。   The present invention relates to a floating undulation gate facility that automatically opens and closes using hydraulic force and gravity as a driving force, and allows the door body to be forcibly raised and lowered. Relates to the device.

河川堤防の樋管に、河川水の逆流防止を目的として河川水位の変化に応じて浮体式の扉体を自動的に開閉作動させることが可能な浮体式起伏ゲート設備が設置されている。   A floating undulation gate facility that can automatically open and close a floating door body in response to changes in the river water level is installed on the river bank of the river bank to prevent backflow of river water.

図６は、河川堤防の樋門の出口を開放・閉塞するゲート設備として設置された従来の浮体式起伏型ゲート設備を示す側断面図であり、同図の（ａ）は全閉状態を示し、（ｂ）は開放状態を示す。   FIG. 6 is a side sectional view showing a conventional floating undulating gate facility installed as a gate facility that opens and closes the exit of the lock of the river bank, and (a) of the figure shows a fully closed state. , (B) shows an open state.

図６において、河川堤防の樋管の出口に浮体式起伏型扉体２５が設置されている。この浮体式起伏型扉体２５は、樋管出口の水路部床にヒンジ２６で設置されており、水路部の上下流の水位変化による水圧力（浮力）を利用して樋管の出口を自動開閉するようになっている。２７は側部戸当金物である。   In FIG. 6, a floating undulating door 25 is installed at the exit of a river bank. The floating undulating door body 25 is installed on the floor of the channel at the exit of the pipe through a hinge 26, and automatically uses the water pressure (buoyancy) due to the change in the water level upstream and downstream of the channel. It opens and closes. 27 is a side door hardware.

図６（ａ）に示すように、本河川側の水位４１が支川側（樋管）の水位４２より高いときは、浮体式起伏型扉体２５が起立して樋管出口を閉塞し、水の逆流を防止する。また、本河川側の水位４１が支川側（樋管）の水位４２に近づくと、浮体式起伏型扉体２５が徐々に開放し、本河川側の水位４１が支川側（樋管）の水位４２より低くなると、図６（ｂ）に示すように浮体式起伏型扉体２５が開放して支川側（樋管）の水が本河川側に自然排水される。   As shown in FIG. 6 (a), when the water level 41 on the main river side is higher than the water level 42 on the tributary river side (the pipe), the floating undulating door body 25 stands up to close the water pipe outlet, Prevent backflow. Further, when the water level 41 on the main river side approaches the water level 42 on the tributary side (pipe pipe), the floating undulating door body 25 is gradually opened, and the water level 41 on the main river side becomes the water level on the tributary side (pipe pipe). If it becomes lower than 42, as shown in FIG.6 (b), the floating type undulating type door body 25 will open | release, and the water of the tributary side (soot pipe) will be drained naturally to this river side.

このように、このゲート形式は、水路河床に下部ヒンジ方式で設置された浮体式の扉体がゲートの上・下流水位変化に対し、その水圧作用力と重力を原動力とし的確に開閉作動することから、人為的な操作を必要とせずに樋管の止水・排水管理が可能となる。   In this way, in this gate type, the floating door installed on the channel bed using the lower hinge system opens and closes accurately with the hydraulic force and gravity as the driving force against the change in the water level upstream and downstream of the gate. Therefore, it is possible to manage the water shutoff and drainage of the pipe without requiring any manual operation.

しかしながら、従来の浮体式起伏型ゲート設備は、ゲート全開時において倒伏した扉体の上部又は下部河床部に土砂が堆積すると扉体の完全な起立・倒伏動作が困難となり、土砂堆積が過度に進行すると、堆積土砂の重量によって扉体の自動起立作動が不可能になるなどの問題点を有している。   However, in the conventional floating type undulating gate equipment, if the sediment accumulates on the upper or lower riverbed of the fallen door when the gate is fully opened, it becomes difficult to complete the standing and lying down of the door, and the sediment accumulation proceeds excessively. Then, there is a problem that the automatic standing operation of the door body becomes impossible due to the weight of the sediment.

この問題に対応するため、図５に示すように、小形の浮体式起伏ゲート設備において、扉体２５の先端のワイヤーロープ連結部２４にワイヤーロープ２２の一端を取付け、ワイヤーロープ２２の他端を転向滑車２３、ワイヤーガイド２９を介してワイヤー巻取装置３１のドラムに巻き取り・巻き戻し可能に連結する。ワイヤー巻取装置３２のドラムの回転操作によってワイヤーロープ２２を巻き取りあるいは巻出しにより扉体２５を強制的に起立・倒伏作動させることができる扉体操作装置を設置した事例がある。なお、３０は上部戸当金物、３１は上部支持金物である。   In order to cope with this problem, as shown in FIG. 5, in a small floating undulation gate facility, one end of the wire rope 22 is attached to the wire rope connecting portion 24 at the front end of the door body 25, and the other end of the wire rope 22 is connected to the other end. It connects with the drum of the wire winding device 31 via the turning pulley 23 and the wire guide 29 so that winding and rewinding are possible. There is an example in which a door body operating device is installed that can force the door body 25 to stand up and fall by winding or unwinding the wire rope 22 by rotating the drum of the wire winding device 32. In addition, 30 is an upper door hardware and 31 is an upper support hardware.

特許第３４８８６５３号明細書Japanese Patent No. 3488653

しかしながら、扉体２５の自由な自動起立・倒伏動作を可能とするためには、全倒伏状態の扉体２５の位置に対応するワイヤーロープ２２の巻出し長さが必要となる。このため、扉体２５が倒伏状態から、図５に示すように自動起立作動を行っている状態ではワイヤーロープ２２が扉体上面で弛んだ状態となり、この弛んだワイヤーロープ２２がゲート自動全閉時において扉体２５と上部戸当金物３０や上部支持金物３１との間に挟まり込み、ゲート不完全閉作動障害を発生させるという重大な問題点を有している。   However, in order to enable the door body 25 to automatically stand up and fall down freely, the unwinding length of the wire rope 22 corresponding to the position of the door body 25 in the fully lowered state is required. Therefore, when the door body 25 is in the lying down state and the automatic standing operation is performed as shown in FIG. 5, the wire rope 22 is slackened on the top surface of the door body, and the slackened wire rope 22 is automatically closed at the gate. In some cases, the door body 25 is caught between the upper door hardware 30 and the upper support hardware 31, which causes a serious problem that an incomplete gate closing operation failure occurs.

そこで、本発明は、扉体を強制的に起立・倒伏作動が可能な浮体式起伏ゲートの扉体の自動起立・倒伏作動時において、扉体でワイヤーロープが弛むことなく常時緊張状態を確保してゲート全閉作動に支障が発生しない、浮体式起伏型ゲートの扉体起立・倒伏作動装置を提供するものである。   Therefore, the present invention ensures a constant tension state without the wire rope slackening at the door body when the door body of the floating type hoisting gate capable of forcibly raising and lowering the door body. Therefore, the present invention provides a door body standing / falling operation device for a floating undulation type gate that does not cause any trouble in the gate full closing operation.

前記の問題点を解決するため、本発明の浮体式起伏ゲートの扉体起立・倒伏作動装置は、河川堤防等に設けられる樋管に水路河床部ヒンジ方式で設置され、河川水位の変動に対して自動的に扉体が起立・倒伏作動して樋管通水断面を開放および閉鎖する浮体式起伏ゲート設備であって、扉体先端部にワイヤーロープの一端を取り付け、同ワイヤーロープの他端を巻取り・巻出しドラムに連結し、巻取り・巻出しドラムを回転作動させることによって扉体を強制的に起立作動させてゲート閉操作を行う扉体起立・倒伏作動装置において、前記巻取り・巻出しドラムの駆動軸と前記巻取り・巻出しドラムを回転させる動力発生装置の入力軸がクラッチを介して接続・開放可能に連結され、さらに前記ワイヤー巻取り・巻出しドラムの駆動軸には常にワイヤー巻取り方向に回転力を作用させるバネ式緊張装置が連結されるとともに、ワイヤー巻出し方向の回転速度を制御する遠心ブレーキ装置が連結されていることを特徴とする。   In order to solve the above-mentioned problems, the floating body hoisting gate door body standing / falling operation device according to the present invention is installed in a canal pipe provided on a river dike or the like by a waterway riverbed hinge system to prevent changes in river water level. This is a floating hoisting gate facility that automatically opens and closes the cross-pipe water flow section when the door body rises and falls and attaches one end of the wire rope to the end of the door body, and the other end of the wire rope In a door body standing / falling operation device that performs a gate closing operation by forcibly raising the door body by rotating the winding / unwinding drum and rotating the winding / unwinding drum. The drive shaft of the unwinding drum and the input shaft of the power generating device that rotates the winding / unwinding drum are connected via a clutch so as to be connectable / disengageable, and further connected to the drive shaft of the wire winding / unwinding drum Always With spring tensioning device is connected for applying a rotational force to the wire winding direction, characterized in that the centrifugal braking device for controlling the rotational speed of the wire unwinding direction is connected.

本発明の浮体式起伏ゲートの扉体起立・倒伏作動装置は、クラッチを開放した状態において、扉体が水位変動により自動起立作動する場合は巻取りドラムがバネ式緊張装置によって常に巻取り方向に回転しようとすることによりワイヤーの弛み発生を防止する。   In the floating body hoisting gate of the present invention, when the door is automatically erected by the water level fluctuation with the clutch released, the winding drum is always in the winding direction by the spring tension device. Prevents loosening of the wire by trying to rotate.

反対にクラッチを開放して自動倒伏作動時には、遠心ブレーキ装置によって扉体の急速な倒伏動作を防止することができる。   On the other hand, when the automatic release operation is performed by releasing the clutch, the rapid braking operation of the door body can be prevented by the centrifugal brake device.

図１において、装置架台１２上に設置される動力発生装置としてウォーム減速機１、多板クラッチ２、ギヤボックス（変速機）３、駆動軸４が順次連結され、駆動軸４にはワイヤー巻取り・巻出しドラム５が固定され、ウォーム減速機１を手動ハンドル操作により回転させ、多板クラッチ２、ギヤボックス（変速機）３及びワイヤー巻取り・巻出しドラム５を回転作動させることができる機構となっている。多板クラッチ２はクラッチ操作ハンドル１０で入り・切りされる。   In FIG. 1, a worm speed reducer 1, a multi-plate clutch 2, a gear box (transmission) 3, and a drive shaft 4 are sequentially connected as a power generation device installed on the device base 12. A mechanism in which the unwinding drum 5 is fixed and the worm speed reducer 1 is rotated by a manual handle operation so that the multi-plate clutch 2, the gear box (transmission) 3 and the wire winding / unwinding drum 5 can be rotated. It has become. The multi-plate clutch 2 is turned on and off by the clutch operation handle 10.

ワイヤー巻取り・巻出しドラム５は、駆動軸４によって渦巻きバネからなるバネ式緊張装置６と連結している。バネ式緊張装置６はワイヤー巻取り・巻出しドラム５がワイヤーロープ巻出し回転することによってねじられるものとする。また、ワイヤー巻取り・巻出しドラム５は、駆動軸４、ギヤボックス３、軸継手７、遠心ブレーキ軸８を経由して遠心ブレーキ９と連結している。遠心ブレーキ軸８には開度計１１が設けられ、扉体の起立・倒伏動作にともない駆動軸４、ギヤボックス３、軸継手７、遠心ブレーキ軸８の回転が伝達されて扉体の開度が表示される。   The wire winding / unwinding drum 5 is connected by a drive shaft 4 to a spring tensioning device 6 formed of a spiral spring. The spring tensioning device 6 is twisted when the wire winding / unwinding drum 5 rotates by unwinding the wire rope. The wire winding / unwinding drum 5 is connected to the centrifugal brake 9 via the drive shaft 4, the gear box 3, the shaft coupling 7, and the centrifugal brake shaft 8. The centrifugal brake shaft 8 is provided with an opening meter 11, and the rotation of the drive shaft 4, gear box 3, shaft joint 7, and centrifugal brake shaft 8 is transmitted as the door body rises and falls to open the door body. Is displayed.

図２及び図３において、本発明の扉体作動装置２１のワイヤー巻取りドラム５にワイヤーロープ２２の一端が連結され、浮体構造で起伏型の扉体２５の上部に設けられたワイヤーロープ連結部２４にワイヤーロープ２２の一端が連結されている。   2 and 3, one end of the wire rope 22 is connected to the wire winding drum 5 of the door body operating device 21 of the present invention, and the wire rope connecting portion provided on the upper part of the undulating door body 25 with a floating structure. One end of the wire rope 22 is connected to 24.

ワイヤーロープ２２は、側部戸当金物２７に設けられたワイヤー溝２８内に納められ、樋管の通水断面外とし、排水時の流木・塵芥による支障が発生しないようにされている。 ワイヤー溝２８内には転向滑車２３、ワイヤーガイド２９が設置され、ワイヤーロープ２２が円滑に巻き取り、巻出しできる経路が確保されている。   The wire rope 22 is housed in a wire groove 28 provided on the side door hardware 27 and is outside the cross section of the water pipe so as not to cause trouble due to driftwood and dust during drainage. A turning pulley 23 and a wire guide 29 are installed in the wire groove 28, and a path through which the wire rope 22 can be smoothly wound and unwound is secured.

図１に示すように、多板クラッチ２を接続した状態でウォーム減速機１をハンドル操作によって浮体構造起伏型扉体２５を閉操作すると、ワイヤー巻取り・巻出しドラム５がワイヤーロープ２２を巻き取り、図３（ａ）に示すとおり、扉体２５を起立作動させることができる。   As shown in FIG. 1, when the floating structure undulating door 25 is closed by operating the worm speed reducer 1 with the multi-plate clutch 2 connected, the wire winding / unwinding drum 5 winds the wire rope 22. As shown in FIG. 3A, the door body 25 can be operated upright.

同様に、多板クラッチ２を接続した状態でウォーム減速機１をハンドル操作によって扉体２５を開操作すると、ワイヤー巻取り・巻出しドラム５がワイヤーロープ２２を巻出し、図３（ｂ）に示すとおり扉体２５を自重によって倒伏作動させることができる。   Similarly, when the door body 25 is opened by operating the worm speed reducer 1 with the multi-plate clutch 2 connected, the wire winding / unwinding drum 5 unwinds the wire rope 22, as shown in FIG. As shown, the door body 25 can be laid down by its own weight.

図３（ａ）に示す扉体起立状態では、ワイヤーロープ２２には扉体２５の自重による倒伏方向モーメントにより緊張力が作用している。この状態で、図１に示すクラッチ入り切り操作ハンドル１０を操作して多板クラッチ２を開放することにより、ワイヤー巻取り・巻出しドラム５を巻出し方向に自由回転させ、扉体２５を自重によって倒伏作動させることができる。   In the door body standing state shown in FIG. 3A, a tension force acts on the wire rope 22 due to a falling direction moment due to the weight of the door body 25. In this state, by operating the clutch on / off operation handle 10 shown in FIG. 1 to release the multi-plate clutch 2, the wire winding / unwinding drum 5 is freely rotated in the unwinding direction, and the door body 25 is moved by its own weight. The lodging can be operated.

このとき、ワイヤー巻取り・巻出しドラム５と連係している遠心ブレーキ９が作用して、ワイヤー巻取り・巻出しドラム５の回転速度を制御し、扉体２５の倒伏速度を制御し、急速な倒伏作動による事故の発生や、設備損傷の発生を防止する。   At this time, the centrifugal brake 9 linked to the wire winding / unwinding drum 5 acts to control the rotation speed of the wire winding / unwinding drum 5 and to control the falling speed of the door body 25, thereby rapidly Prevents accidents and equipment damage caused by proper lodging.

図４に示すように、ゲートの自動作動時には、多板クラッチ２を開放した状態とする。扉体２５が全倒伏し、ワイヤーロープ２２が巻き出された状態においてバネ式緊張装置６によりワイヤーロープ２２には常にバネ式緊張装置６の渦巻きバネによる緊張力が作用している。   As shown in FIG. 4, when the gate is automatically operated, the multi-plate clutch 2 is released. In the state where the door body 25 is fully laid down and the wire rope 22 is unwound, the tension force by the spiral spring of the spring tension device 6 is always applied to the wire rope 22 by the spring tension device 6.

図４に示すように、河川水位の変化によって扉体２５が起立作動すると、ワイヤー巻取り・巻出しドラム５がバネ装置６によって巻取り方向に回転してワイヤーロープ２２を巻取る。これによりワイヤーロープ２２に弛みが発生することを防止する。   As shown in FIG. 4, when the door body 25 rises due to a change in the river water level, the wire winding / unwinding drum 5 is rotated in the winding direction by the spring device 6 to wind the wire rope 22. This prevents slack in the wire rope 22.

河川水位の変化によって扉体２５が倒伏作動するときは、ワイヤー巻取り・巻き戻しドラム５がバネ装置６をねじりながら、巻出し方向に回転してワイヤーロープ２２を巻き出す。   When the door body 25 inclines due to a change in the river water level, the wire winding / rewinding drum 5 rotates in the unwinding direction while twisting the spring device 6 to unwind the wire rope 22.

以上のように、任意操作によって確実に扉体を開閉操作可能で、かつ自動作動に対しワイヤー巻取り・巻き戻しドラムを追従回転作動させることによりワイヤーロープの弛みを防止することができる。   As described above, it is possible to reliably open and close the door body by an arbitrary operation, and it is possible to prevent the wire rope from slacking by rotating the wire winding / rewinding drum following the automatic operation.
