Description

本発明は、ワイヤーロープに塗布された油を除去するための冶具及び方法に関する。   The present invention relates to a jig and method for removing oil applied to a wire rope.

従来より、水力発電所の取水口などに設けられたゲートを開閉するためにゲートの上部を吊り下げるワイヤーロープには、腐食を防止し、また、摩擦による磨耗防止のために、表面にグリースなどの油を塗布している。また、定期的に前回塗布した油をへらなどを使って全て削ぎ落とし、再度、塗布する塗り替え作業を行っている。   Conventionally, the wire rope that hangs the upper part of the gate to open and close the gate provided at the intake of the hydroelectric power plant, etc., has been coated with grease on its surface to prevent corrosion and to prevent wear due to friction. The oil is applied. Also, the oil applied last time is periodically scraped off with a spatula or the like, and the repainting operation is performed again.

ところで、この油の塗り替え作業は、安全性確保のため水力発電所における発電を停止した状態で行う。しかしながら、通常、水力発電所を停止できるのは、電力使用量が少ない冬季に限られ、冬季は外気温が低く、塗布された油が硬化してしまう。このため、除去作業に非常に手間がかかるという問題があった。   By the way, this oil repainting operation is performed in a state where power generation in the hydroelectric power station is stopped to ensure safety. However, normally, hydropower plants can be shut down only in the winter when the amount of power used is low, and in winter the outside air temperature is low and the applied oil is hardened. For this reason, there has been a problem that the removal work is very time-consuming.

本発明は、上記の問題に鑑みなされたものであり、その目的は、外気温が低い季節であっても、スムーズにワイヤーロープに塗布された油の除去作業を行うことができるようにすることである。   The present invention has been made in view of the above problems, and an object of the present invention is to enable smooth removal of oil applied to a wire rope even in a season when the outside air temperature is low. It is.

本発明の油除去冶具は、ワイヤーロープに塗布された油を除去するための冶具であって、前記油を加熱する加熱部と、前記繊維状材料をより合わせてなるひも状部材を張設してなる油除去部と、を備えることを特徴とする。   The oil removing jig of the present invention is a jig for removing oil applied to a wire rope, and stretches a heating part for heating the oil and a string-like member formed by combining the fibrous material. And an oil removing section.

上記の油除去冶具において、前記加熱部は、前記ワイヤーロープに当接可能な金属製の帯状板材と、前記帯状板材を加熱するヒータとからなるものであってもよい。
また、前記油除去部は、前記ひも状部材の張力を調整する機構を備えてもよい。 In the oil removing jig described above, the heating unit may include a metal belt-shaped plate that can contact the wire rope and a heater that heats the belt-shaped plate.
The oil removal unit may include a mechanism for adjusting the tension of the string-like member.

また、本発明の油除去方法は、ワイヤーロープに塗布された油を除去する方法であって、前記油を加熱し、繊維状材料を縒り合わせてなるひも状部材を前記ワイヤーロープに押し付けた状態で、前記ひも状部材をワイヤーロープに沿って摺動させることにより、前記油を削ぎ取ることを特徴とする。   Moreover, the oil removal method of the present invention is a method for removing oil applied to a wire rope, in which the oil is heated and a string-like member formed by twisting together fibrous materials is pressed against the wire rope. Then, the oil is scraped off by sliding the string-like member along the wire rope.

本発明によれば、ワイヤーロープに塗布された油を加熱部により加熱し、軟化させ、軟化した油をひも状部材により削ぎ落とすことができるため、外気温が低い季節であっても、スムーズに油の除去作業を行うことができる。   According to the present invention, the oil applied to the wire rope is heated and softened by the heating unit, and the softened oil can be scraped off by the string-like member. Oil removal work can be performed.

以下、本発明のワイヤーロープの油除去冶具の一実施形態を図面を参照しながら詳細に説明する。
図１〜図４は、本実施形態のワイヤーロープの油除去冶具１００を示す図であり、図１は正面図、図２は裏面図、図３は上面図（図１におけるＡ矢視図）、図４は側面図（図１におけるＢ矢視図）である。発電所の取水口等のゲートを上下させるためのワイヤーロープには、磨耗や腐食から保護するために、その表面にグリースなどの油が塗布されている。本実施形態の油除去冶具は、ワイヤーロープに塗布された油の塗り替え作業の際に、塗布された油を除去するためのものである。図１〜図４に示すように、油除去冶具１００は、把持部２０、この把持部２０に接続されたＵ字型の枠材３０、及び枠材３０の両先端部にこの枠材３０に対して直交するように（すなわち、図１の紙面と垂直方向に延びるように）取り付けられた一対の板材３２からなる冶具本体１０と、一対の板材３２の一方の端部同士を結ぶように取り付けられたひも状部材４０と、一対の板材３２の他方の端部同士を結ぶように取り付けられた銅板５０と、この銅板５０を加熱する電熱線５２及び電池５３からなる加熱部７０と、から構成される。 Hereinafter, an embodiment of an oil removing jig for a wire rope of the present invention will be described in detail with reference to the drawings.
1-4 is a figure which shows the oil removal jig | tool 100 of the wire rope of this embodiment, FIG. 1 is a front view, FIG. 2 is a back view, FIG. 3 is a top view (A arrow view in FIG. 1). 4 is a side view (viewed in the direction of arrow B in FIG. 1). Oil such as grease is applied to the surface of a wire rope for moving up and down a gate such as a water intake of a power plant in order to protect it from wear and corrosion. The oil removal jig of this embodiment is for removing the applied oil during the repainting operation of the oil applied to the wire rope. As shown in FIGS. 1 to 4, the oil removing jig 100 includes a gripping portion 20, a U-shaped frame member 30 connected to the gripping portion 20, and the frame member 30 at both ends of the frame member 30. The jig body 10 composed of a pair of plate members 32 attached so as to be orthogonal to each other (that is, so as to extend in a direction perpendicular to the paper surface of FIG. 1) and one end of the pair of plate members 32 are attached to each other. The cord-like member 40 formed, a copper plate 50 attached so as to connect the other ends of the pair of plate members 32, and a heating unit 52 composed of a heating wire 52 and a battery 53 for heating the copper plate 50. Is done.

枠材２０はＵ字型に成形された鋼材からなり、その中間高さにおいて枠材２０の対向する面を結ぶように補強部材３１が取り付けられている。また、把持部２０は例えば中空のプラスチック製の部材からなる。また、枠材２０の一方の先端部には先端が鋭利に形成されたへら部材８０が取り付けられている。また、把持部２０の基端部には落下防止のためのロープ等を取り付け可能なリング状部材２０Ａが設けられている。   The frame member 20 is made of a steel material formed in a U-shape, and a reinforcing member 31 is attached so as to connect the opposing surfaces of the frame member 20 at an intermediate height. Moreover, the holding part 20 consists of a hollow plastic member, for example. A spatula member 80 having a sharp tip is attached to one tip of the frame member 20. In addition, a ring-shaped member 20 </ b> A to which a rope or the like for preventing the fall can be attached is provided at the proximal end portion of the grip portion 20.

ひも状部材４０としては、例えば、ナイロン製の繊維が縒り合わされてなるナイロンロープなどを用いることができる。板材３２にはその両端部近傍に内周に螺条が形成された孔（不図示）が形成されており、この孔には、孔の内周の螺条に螺合する蝶螺子４２が取り付けられている。ひも状部材４０の両端は、蝶螺子４２の先端に回転自在に接続されたリング状の固定用金具４１に接続されている。また、板材３２には固定用金具４１が回転したときに、固定用金具４１と干渉する位置に回転防止板４３が取り付けられている。したがって、固定用金具４１の回転は回転防止板４３により規制される。   As the string-like member 40, for example, a nylon rope formed by twisting nylon fibers can be used. A hole (not shown) having a thread formed on the inner periphery is formed in the vicinity of both ends of the plate member 32, and a butterfly screw 42 that is screwed into the thread on the inner periphery of the hole is attached to the hole. It has been. Both ends of the string-like member 40 are connected to a ring-shaped fixing bracket 41 that is rotatably connected to the tip of the butterfly screw 42. Further, a rotation preventing plate 43 is attached to the plate 32 at a position where it interferes with the fixing bracket 41 when the fixing bracket 41 rotates. Accordingly, the rotation of the fixing bracket 41 is restricted by the rotation prevention plate 43.

かかる構成によれば、蝶螺子４２を回転させると、蝶螺子４２が板材３２に対して進退し、これとともに固定用金具４１が板材３２に対して進退する。このように蝶螺子４２を回転させ、固定用金具４１を適宜進退させることにより、固定用金具４１の間に取り付けられたひも状部材４０に作用する張力を調整することができる。また、何れか一方の蝶螺子４２を回転すると、ひも状部材４０にねじれが生じる虞があるが、上記のように、蝶螺子４２の端部に回転自在に固定用金具４１を接続し、また、固定用金具４０の回転を回転防止板４３により規制する構成としたため、ひも状部材４０にねじれが生じるのを防止できる。   According to this configuration, when the butterfly screw 42 is rotated, the butterfly screw 42 advances and retreats with respect to the plate material 32, and the fixing bracket 41 advances and retreats with respect to the plate material 32. Thus, the tension acting on the string-like member 40 attached between the fixing metal fittings 41 can be adjusted by rotating the butterfly screw 42 and appropriately moving the fixing metal fittings 41 back and forth. Further, if any one of the butterfly screws 42 is rotated, the string-like member 40 may be twisted. As described above, the fixing bracket 41 is rotatably connected to the end of the butterfly screw 42. Since the rotation of the fixing bracket 40 is restricted by the rotation prevention plate 43, the string-like member 40 can be prevented from being twisted.

銅板５０は、蝶螺子５１により板材３２の間に取り付けられている。銅板５０としては、後述するように、ワイヤーロープ１に付着した油を加熱するべく、作業員が油除去冶具１００をワイヤーロープ１に押し付けた際に、ワイヤーロープ１と銅板５０との接触面積が大きくなるよう、銅板５０が撓む程度の厚さのものを用いるとよい。   The copper plate 50 is attached between the plate members 32 by a butterfly screw 51. As will be described later, the copper plate 50 has a contact area between the wire rope 1 and the copper plate 50 when an operator presses the oil removal jig 100 against the wire rope 1 in order to heat the oil attached to the wire rope 1. It is good to use the thing of the thickness which the copper plate 50 bends so that it may become large.

加熱部７０は、銅板５０の両端部に巻き付けられた電熱線５２と、把持部２０の内部に収容され、電熱線５２に電力を供給する電池５３とからなる。電熱線５２は、銅板５０の端部より枠材３０に沿って把持部２０まで延び、把持部２０の内部を通り電源スイッチ５４を介して電池５３に接続されている。また、電熱線５２の枠材３０に沿って延びる部分の外周には、電熱線５２を保護するとともに、作業中に高温の電熱線５２が露出した状態であると作業員が電熱線５２に触れる虞があるため、ガラスチューブ５５が取り付けられている。   The heating unit 70 includes a heating wire 52 wound around both ends of the copper plate 50, and a battery 53 that is accommodated in the holding unit 20 and supplies power to the heating wire 52. The heating wire 52 extends from the end portion of the copper plate 50 along the frame member 30 to the grip portion 20, passes through the grip portion 20, and is connected to the battery 53 via the power switch 54. In addition, the heating wire 52 is protected on the outer periphery of the portion of the heating wire 52 that extends along the frame member 30, and the worker touches the heating wire 52 when the high-temperature heating wire 52 is exposed during the work. Since there is a possibility, the glass tube 55 is attached.

以下、上記の油除去冶具１００を用いてワイヤーロープ１の油を除去する方法を説明する。
予め、電源スイッチ５４をオンにして、電熱線５２により銅板５０を加熱しておく。そして、銅板５０が充分に加熱されたら、図５に示すように、銅板５０の一方の面をワイヤーロープに押し付けた状態で、油除去冶具１００をワイヤーロープ１に沿って動かし、銅板５０によりワイヤーロープ１に塗布された油を加熱しながら、加熱された油を削ぎ落とす。外気温が低いと油が硬化してしまうが、銅板５０により加熱されて軟化するため、容易に削ぎ落とすことができる。ただし、銅板５０では、ワイヤーロープ１の表面に密着させることができず、ワイヤーロープ１の表面に油の一部が残存する。 Hereinafter, a method for removing oil from the wire rope 1 using the oil removing jig 100 will be described.
The power switch 54 is turned on in advance, and the copper plate 50 is heated by the heating wire 52. When the copper plate 50 is sufficiently heated, the oil removing jig 100 is moved along the wire rope 1 with one surface of the copper plate 50 pressed against the wire rope as shown in FIG. While heating the oil applied to the rope 1, the heated oil is scraped off. If the outside air temperature is low, the oil will harden, but since it is heated and softened by the copper plate 50, it can be easily scraped off. However, the copper plate 50 cannot be brought into close contact with the surface of the wire rope 1, and part of the oil remains on the surface of the wire rope 1.

次に、図６に示すように、油除去冶具１００を裏返し、ひも状部材４０をワイヤーロープ１に押し付けて密着させた状態で、油除去冶具１００をワイヤーロープ１に沿って動かし、ひも状部材４０によりワイヤーロープ１に塗布された油を削ぎ落とす。これにより、銅板５０により除去できずにワイヤーロープ１の表面に残存した油を確実に取り除くことができる。なお、予め、ひも状部材４０がワイヤーロープ１に確実に密着するように適宜蝶螺子４２を回転させて、ひも状部材４０の張力を調整するとよい。また、ひも状部材４０が痛んでしまった場合には、適宜なタイミングで交換し、再度張力を調整するとよい。   Next, as shown in FIG. 6, the oil removing jig 100 is turned upside down, and the string removing member 100 is moved along the wire rope 1 in a state where the string removing member 40 is pressed against the wire rope 1 and brought into close contact with the wire rope 1. 40, the oil applied to the wire rope 1 is scraped off. Thereby, the oil which cannot be removed by the copper plate 50 and remains on the surface of the wire rope 1 can be surely removed. In addition, it is good to adjust the tension | tensile_strength of the string-like member 40 previously by rotating suitably the thumbscrew 42 so that the string-like member 40 may contact | adhere to the wire rope 1 reliably. Moreover, when the string-like member 40 is damaged, it is preferable to replace it at an appropriate timing and adjust the tension again.

また、この際、ワイヤーロープ１に素線切れが生じていると、切れた素線がひも状部材４０に引っかかる。このため、油の除去作業を行うとともに、ワイヤーロープ１の素線切れを発見することができる。   At this time, if the wire rope 1 is broken, the broken wire is caught by the string-like member 40. For this reason, while performing the removal operation | work of oil, the strand breakage of the wire rope 1 can be discovered.

さらに、ワイヤーロープ１を構成するストランドの間の隙間に油が付着している場合には、この隙間に枠材のへら部材８０を挿入して掻き出す。
以上の工程により、ワイヤーロープ１に付着した油を除去することができる。 Further, when oil adheres to the gaps between the strands constituting the wire rope 1, the spatula member 80 of the frame material is inserted into the gaps and scraped out.
Through the above steps, the oil attached to the wire rope 1 can be removed.

本実施形態によれば、外気温が低いために硬化してしまった油を銅板５０により加熱し、軟化させた上で油の削ぎ取り作業を行うため、容易に油を除去することができる。   According to the present embodiment, the oil that has hardened due to the low outside air temperature is heated by the copper plate 50 and softened, and then the oil is scraped off. Therefore, the oil can be easily removed.

また、ひも状部材４０の両端を蝶螺子４２に固定用金具４１を介して蝶螺子４２に取り付けることとしたため、蝶螺子４２を回転させることによりひも状部材４０の張力を調整することができ、これにより、確実にひも状部材４０をワイヤーロープ１に密着させることができる。   Further, since both ends of the string-like member 40 are attached to the butterfly screw 42 via the fixing bracket 41 to the butterfly screw 42, the tension of the string-like member 40 can be adjusted by rotating the butterfly screw 42. Thereby, the string-like member 40 can be made to contact | adhere to the wire rope 1 reliably.

なお、本実施形態では、銅板５０により油を加熱する構成としたが、これに限らず、例えば、油除去冶具１００にドライヤーのように温風が吹き出すような装置を設けておき、この装置により油を加熱してもよい。この場合、銅板５０により油を除去する作業は行わず、ひも状部材４０により油を除去すればよい。   In the present embodiment, the oil is heated by the copper plate 50. However, the present invention is not limited to this. For example, a device that blows warm air like a dryer is provided in the oil removing jig 100. The oil may be heated. In this case, the operation of removing the oil with the copper plate 50 is not performed, and the oil may be removed with the string member 40.
