Description

本発明は、例えば、ダムやロープウェイなどに使用されるロープ巻上機を収納するためのロープ巻上室内への鳥類等の小動物の侵入を防止する侵入防止装置、この侵入防止装置を備えてなるロープ巻上室、及び屋外ロープ設備に関する。   The present invention includes, for example, an intrusion prevention device for preventing entry of small animals such as birds into a rope hoisting chamber for storing a rope hoist used for a dam, a ropeway, and the like, and the intrusion prevention device. The present invention relates to a rope winding room and outdoor rope equipment.

例えばダムの洪水路ゲートやロープウェイなどのように、ロープを利用して稼働する屋外ロープ設備では、ロープ巻上機を収納するためのロープ巻上室が設けられている。ロープ巻上室には、屋外へロープを延出させるためのロープ引き出し口が設けられている。   For example, an outdoor rope facility that operates using a rope, such as a dam floodway gate and a ropeway, has a rope hoisting chamber for storing a rope hoisting machine. The rope winding chamber is provided with a rope outlet for extending the rope to the outdoors.

ところが、このロープ引き出し口は、常に開放されているため、ここからロープ巻上室内に鳥類等が侵入し、巣を作ったりロープ巻上室内を糞で汚してしまうことがあった。このため、巣の除去や清掃に時間と費用を費やしていた。   However, since this rope outlet is always open, birds or the like invaded the rope hoisting chamber from there, and sometimes a nest was formed or the rope hoisting chamber was contaminated with feces. For this reason, time and expense were spent on removal and cleaning of the nest.

鳥類等の侵入を防ぐための一般的な方法としては、例えば、特許文献１に開示されているように、ビニールの垂れ幕や糸などを設置する方法などがある。
特開２００１−３４６４９９号公報 As a general method for preventing the entry of birds or the like, for example, as disclosed in Patent Document 1, there is a method of installing a vinyl banner or a thread.
JP 2001-346499 A

しかしながら、この侵入防止方法は、マンションのベランダなどで使用する場合には有効であるが、上記屋外ロープ設備におけるロープ引き出し口にそのまま適用すると、ロープを巻き上げる際に、設置した垂れ幕や糸などを一緒に巻き込んでしまう虞があった。また、垂れ幕や糸を定期的に交換、及び清掃する必要があるため、メンテナンスに手間がかかるという問題があった。   However, this intrusion prevention method is effective when used on the verandas of condominiums. However, when applied as it is to the rope outlet in the outdoor rope facility, when the rope is wound up, the installed banner or thread is used together. There was a risk of getting involved. In addition, since it is necessary to periodically change and clean the banner and the thread, there is a problem that the maintenance is troublesome.

そこで本発明は、メンテナンスが不要で、かつロープ巻上室内への鳥類等の小動物の侵入を確実に防止できるロープ巻上室の侵入防止装置を提供することを目的とする。   SUMMARY OF THE INVENTION An object of the present invention is to provide a rope hoisting room intrusion prevention apparatus that can prevent maintenance of small animals such as birds into a rope hoisting room without maintenance.

本発明によれば、メンテナンスが不要で、かつロープ巻上室内への鳥類等の小動物の侵入を確実に防止できる侵入防止装置を提供することができる。   According to the present invention, it is possible to provide an intrusion prevention device that does not require maintenance and can reliably prevent entry of small animals such as birds into the rope hoisting room.

以下、本発明の実施形態を、図面を参照して詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

本発明に係るロープ巻上室への侵入防止装置は、ロープを屋外へ延出させるためのロープ引き出し口を設けたロープ巻上室内に、鳥類等の小動物が侵入するのを防止するための装置である。従って、このようなロープ巻上室を備えた屋外ロープ設備ならばどのようなものでも適用可能である。例えば、ダムの洪水吐ゲートやロープウェイ、或いは、ロープで操作する遊園地の乗り物などに適用することが想定できる。本実施形態では、ダム洪水吐ゲート１０に適用した場合について説明する。   The apparatus for preventing invasion into the rope hoisting chamber according to the present invention is an apparatus for preventing small animals such as birds from entering the rope hoisting chamber provided with a rope outlet for extending the rope to the outdoors. It is. Therefore, any outdoor rope equipment provided with such a rope hoisting chamber can be applied. For example, it can be assumed to be applied to a spillway gate of a dam, a ropeway, or an amusement park vehicle operated by a rope. This embodiment demonstrates the case where it applies to the dam spillway gate 10. FIG.

図１は、ダムの洪水吐ゲート１０を模式的に示す断面図である。同図に示すように、ダムの洪水吐ゲート１０は、ロープ巻上機２０、このロープ巻上機２０を収納するためのロープ巻上室３０、ドラム４０、扉体５０などで構成されている。   FIG. 1 is a cross-sectional view schematically showing a spillway gate 10 of a dam. As shown in the figure, the spillway gate 10 of the dam is composed of a rope hoisting machine 20, a rope hoisting chamber 30 for storing the rope hoisting machine 20, a drum 40, a door body 50, and the like. .

洪水吐ゲート１０は、ロープ巻上機２０でロープ６０を巻き上げて、ロープ６０に接続された扉体５０を吊り上げたり、ロープ６０を緩めて扉体５０を下ろすことによってゲートを開閉する設備である。ロープ６０は、ドラム４０を介して扉体５０に連結されている。ロープ巻上室３０には、ロープ巻上室３０内から屋外へロープ６０を延出させるためのロープ引き出し口７０が設けられている。侵入防止装置１００は、このロープ引き出し口７０に設けられる。   The spillway gate 10 is a facility that opens and closes the gate by hoisting the rope 60 with the rope hoist 20 and lifting the door body 50 connected to the rope 60, or loosening the rope 60 and lowering the door body 50. . The rope 60 is connected to the door body 50 via the drum 40. The rope winding chamber 30 is provided with a rope outlet 70 for extending the rope 60 from the rope winding chamber 30 to the outside. The intrusion prevention device 100 is provided at the rope outlet 70.

以下、図２から図８を参照してロープ巻上室３０の侵入防止装置１００の構造を説明する。   Hereinafter, the structure of the intrusion prevention device 100 in the rope hoisting chamber 30 will be described with reference to FIGS.

図２はロープ引き出し口７０の拡大断面図である。図２において、画面右側はロープ巻上室３０内側であり、画面の左側は屋外側である。すなわち、ロープ６０は、ロープ巻上室３０内からロープガイドローラ８０を介してロープ引き出し口７０より屋外へ延出する。   FIG. 2 is an enlarged cross-sectional view of the rope outlet 70. In FIG. 2, the right side of the screen is the inside of the rope hoisting chamber 30, and the left side of the screen is the outdoor side. In other words, the rope 60 extends from the rope winding chamber 30 to the outside through the rope guide roller 80 through the rope outlet 70.

侵入防止装置１００は、ロープ巻上機２０からロープ引き出し口７０へ向かうロープ６０に下側から接触するロープ接触部材１１０と、このロープ接触部材１１０の両端に接続されてロープ巻上室の内側へ延びる支持部材１２０と、支持部材１２０を回動自在に支持する支持軸１３０と、前記ロープ接触部材１１０に一端を回動自在に固定され、ロープ接触部材１１０から上方、及び下方にそれぞれ延びてロープ引き出し口７０を塞ぐ上板１４０及び下板１５０と、上板１４０の上部を支持する支持具１６０と、を備えている。   The intrusion prevention device 100 includes a rope contact member 110 that contacts the rope 60 from the rope hoist 20 toward the rope outlet 70 from below, and is connected to both ends of the rope contact member 110 to the inside of the rope hoisting chamber. A support member 120 that extends, a support shaft 130 that rotatably supports the support member 120, and a rope contact member 110 having one end pivotally fixed to the rope contact member 110 and extending upward and downward from the rope contact member 110, respectively. An upper plate 140 and a lower plate 150 that block the drawer opening 70 and a support 160 that supports the upper portion of the upper plate 140 are provided.

図３は、支持具１６０の一実施形態を示した図である。支持具１６０は、同図に示すように、単に上板１４０を突起物で挟んで支持するものであってもよいし、例えば上板１４０との接触部分にローラなどを設けてもよい。   FIG. 3 is a view showing an embodiment of the support 160. As shown in the figure, the support tool 160 may simply support the upper plate 140 with protrusions, or may be provided with a roller or the like at a contact portion with the upper plate 140, for example.

図４から図７は、ロープ接触部材１１０、及び支持部材１２０の態様を例示する図である。これらの図において、上板１４０、下板１５０などは省略して示している。また、支持部材１２０の端部は回動自在に固定されていればよいので、支持軸１３０を省略することも可能である。   4 to 7 are views illustrating aspects of the rope contact member 110 and the support member 120. In these drawings, the upper plate 140, the lower plate 150, etc. are omitted. Moreover, since the end part of the support member 120 should just be fixed so that rotation is possible, the support shaft 130 can also be abbreviate | omitted.

ロープ接触部材１１０、及び支持部材１２０の態様としては、様々な変形、及び工夫が可能である。具体的には、図４、及び図５に示すように支持部材１２０を複数本設けてもよいし、或いは、図６のように、一本のみでもよい。また、図７に示すように、棒状に限らず板状のものも想定できる。また、ロープ接触部材１１０は、ロープ６０との接触面にローラを設けてもよいし、或いは、ロープ接触部材１１０自体をローラとしてもよい。   As a form of the rope contact member 110 and the support member 120, various deformation | transformation and devices are possible. Specifically, a plurality of support members 120 may be provided as shown in FIGS. 4 and 5, or only one may be provided as shown in FIG. Further, as shown in FIG. 7, not only a rod shape but also a plate shape can be assumed. The rope contact member 110 may be provided with a roller on the contact surface with the rope 60, or the rope contact member 110 itself may be a roller.

ロープ接触部材１１０の両端部には、上板１４０、及び下板１５０がヒンジなどで回動自在に取り付けられる。上板１４０は、後でより詳細に説明するが、ロープ６０の張りの状態の変化に応じて円滑に動作できるように、所定の湾曲形状を有している。一方、下板１５０は、ロープ接触部材１１０と下板１５０との間にロープ６０が通過できる程度の隙間１７０を介して配置される。なお、上板１４０、及び下板１５０を構成する材料は特に制限しないが、例えばステンレス材などであれば、長期間メンテナンスの必要がなくなる。   An upper plate 140 and a lower plate 150 are rotatably attached to both ends of the rope contact member 110 by hinges or the like. As will be described in detail later, the upper plate 140 has a predetermined curved shape so that the upper plate 140 can operate smoothly according to changes in the tension state of the rope 60. On the other hand, the lower plate 150 is disposed between the rope contact member 110 and the lower plate 150 with a gap 170 that allows the rope 60 to pass therethrough. In addition, although the material which comprises the upper board 140 and the lower board 150 is not restrict | limited in particular, if it is a stainless material etc., a long-term maintenance will become unnecessary.

図８は、ロープ引き出し口７０の正面図である。同図において、上板１４０、及び下板１５０とは、ロープ引き出し口７０を塞ぎ鳥類の侵入を防止する。なお、本実施形態では、ロープ巻上室３０内から屋外へ二本のロープ６０を延出させた例を示している。侵入防止装置１００は、このようにロープ引き出し口７０からロープ６０が複数本延出する場合でも適用可能である。   FIG. 8 is a front view of the rope outlet 70. In the figure, an upper plate 140 and a lower plate 150 block the rope outlet 70 to prevent birds from entering. In the present embodiment, an example is shown in which two ropes 60 are extended from the inside of the rope winding upper chamber 30 to the outside. The intrusion prevention device 100 can be applied even when a plurality of ropes 60 extend from the rope outlet 70 as described above.

次に、図９及び図１０を参照して侵入防止装置１００の動作を説明する。なお、これらの図において、画面右側がロープ巻上室３０内側を示し、画面左側が屋外側を示している。また、点線はロープ６０が緩んだ状態を示し、実線はロープ６０が張った状態を示している。   Next, the operation of the intrusion prevention device 100 will be described with reference to FIGS. In these drawings, the right side of the screen shows the inside of the rope hoisting chamber 30 and the left side of the screen shows the outdoor side. A dotted line indicates a state where the rope 60 is loosened, and a solid line indicates a state where the rope 60 is stretched.

図９は、ロープ引き出し口７０付近におけるロープ６０の動作を説明するための断面図である。この図によれば、ロープ引き出し口７０を通過するロープ６０の高さは、ロープ６０の張りの状態により変化する。すなわち、図中に点線で示すように、ロープ６０が緩んだ状態の場合は、ロープ６０はロープ引き出し口７０の下端部付近を通過するが、ロープ６０が張った状態の場合は、緩んだ状態よりも高い位置を通過して屋外へ延出する。   FIG. 9 is a cross-sectional view for explaining the operation of the rope 60 near the rope outlet 70. According to this figure, the height of the rope 60 passing through the rope outlet 70 varies depending on the tension state of the rope 60. That is, as shown by a dotted line in the drawing, when the rope 60 is loose, the rope 60 passes near the lower end of the rope outlet 70, but when the rope 60 is tight, the rope 60 is loose. It passes through a higher position and extends outdoors.

ロープ引き出し口７０は、このようなロープ６０の張りの状態によるロープ６０の上下動を許容できるよう、大きな開口部となっている。従って、このままではロープ巻上室３０内に鳥類等の小動物が容易に侵入できてしまう。   The rope outlet 70 has a large opening so that the rope 60 can be allowed to move up and down due to the tension of the rope 60. Therefore, in this state, small animals such as birds can easily enter the rope winding upper chamber 30.

図１０は、侵入防止装置１００の動作状態を示す断面図である。同図に示すように、侵入防止装置１００は、ロープ６０の張りの状態に応じて動作してロープ引き出し口７０を塞ぎ、ロープ巻上室３０内への鳥類等の侵入を防止する。   FIG. 10 is a cross-sectional view showing the operating state of the intrusion prevention device 100. As shown in the figure, the intrusion prevention device 100 operates according to the tension state of the rope 60 to block the rope outlet 70 and prevent the entry of birds and the like into the rope hoisting chamber 30.

上述のように、支持部材１２０の支持軸１３０側の端部は、回動自在に固定されている。このため、ロープ接触部材１１０が、支持軸１３０を中心とした円周上を移動することができる。この際、ロープ接触部材１１０に取り付けられた上板１４０、及び下板１５０は、ロープ接触部材１１０と連動して動作する。   As described above, the end of the support member 120 on the support shaft 130 side is fixed so as to be rotatable. For this reason, the rope contact member 110 can move on the circumference around the support shaft 130. At this time, the upper plate 140 and the lower plate 150 attached to the rope contact member 110 operate in conjunction with the rope contact member 110.

また、上板１４０、及び下板１５０は、その一端部を、ロープ接触部材１１０を中心に回動自在に固定されているので、ロープ接触部材１１０とともに上下動しつつ、適宜ロープ接触部材１１０の周囲を移動することができる。このとき、上板１４０は所定の曲率を有しているため、これらの動作が円滑に行われる。   In addition, since the upper plate 140 and the lower plate 150 are fixed at one end thereof so as to be rotatable around the rope contact member 110, the upper plate 140 and the lower plate 150 are moved up and down together with the rope contact member 110 as appropriate. Can move around. At this time, since the upper plate 140 has a predetermined curvature, these operations are performed smoothly.

以上の構成によれば、ロープ接触部材１１０、上板１４０、及び下板１５０は、ロープ６０が上下動しても、この上下動に応じてロープ引き出し口７０を塞いだ状態を保つことができる。従って、ロープ６０の状態に拘わらず鳥類等の小動物の侵入を防ぐことができる。さらに、上板１４０、及び下板１５０は、ロープ６０と直接接触することがないので、ロープ巻上機２０に巻き込まれる虞がない。   According to the above configuration, even when the rope 60 moves up and down, the rope contact member 110, the upper plate 140, and the lower plate 150 can maintain a state in which the rope outlet 70 is closed according to the vertical movement. . Therefore, invasion of small animals such as birds can be prevented regardless of the state of the rope 60. Furthermore, since the upper plate 140 and the lower plate 150 do not come into direct contact with the rope 60, there is no possibility of being caught in the rope hoisting machine 20.
