Description

本発明は、電力線鉄塔の鋼管内部に作られた営巣を撤去して清掃するための、鋼管の営巣撤去工具及び営巣撤去工法に関するものである。 The present invention relates to a nesting removal tool for steel pipes and a nesting removal method for removing and cleaning nests made inside steel pipes of power line towers.

従来から、鋼管内に、例えば、鳥獣や蜂等の営巣を確認した電力線鉄塔が多数発見されている。この営巣により、鋼管内部の腐食点検(例えば、内視鏡点検)が実施できなくなる他、営巣が鋼管内面の腐食に繋がる一要因になっている。 Conventionally, many power line towers have been found in steel pipes, for example, where nesting of birds, beasts, bees, etc. has been confirmed. This nesting makes it impossible to inspect the inside of the steel pipe for corrosion (for example, endoscopic inspection), and the nesting is one of the factors leading to the corrosion of the inner surface of the steel pipe.

このため、上記点検及び腐食防止のための様々な工具が利用されているが、標準的な撤去方法は確立されていないのが現状である。 For this reason, various tools for the above inspection and corrosion prevention are used, but the standard removal method has not been established at present.

そして、従来の営巣撤去方法としては、フレキシブルシャフトに先端ノズルを取り付け、電動ドリルにて回転させながら清掃を行う方法、或いは、貯水タンク(1.000リットル)を配置して高圧洗浄機のノズルを取り付け、清掃を行う方法、更には、電動ドリルにフレキシブルシャフトを取り付けて清掃し、且つコンプレッサのエアーで回収する方法等があった。 As a conventional method for removing nests, a tip nozzle is attached to a flexible shaft and cleaning is performed while rotating with an electric drill, or a water storage tank (1.000 liter) is arranged to install a nozzle of a high pressure washer. There was a method of attaching and cleaning, and a method of attaching a flexible shaft to an electric drill for cleaning and collecting with air from a compressor.

このように、鋼管の内部に作られた営巣を撤去する工法として、電源を要する高圧洗浄機や電動ドリル等を活用した大掛かりな撤去工法が存在していた。 As described above, as a method for removing nests formed inside a steel pipe, there has been a large-scale removal method using a high-pressure washer or an electric drill that requires a power source.

この他、従来の鉄塔における鋼管内部の異物除去手法として、特許文献1に示すように、主柱材を鋼管で構成された鉄塔類の鋼管内部を掃拭するために、主柱材に取り付けられた遮水板の細長い溝より容易に挿入でき、鋼管内部で固まった土砂や蜂の巣およびごみ等の固まりを粉砕することができる鋼管内異物粉砕機が開示されている。 In addition, as a method for removing foreign matter inside steel pipes in conventional steel towers, as shown in Patent Document 1, the main pillar material is attached to the main pillar material in order to wipe the inside of steel pipes of steel towers composed of steel pipes. Disclosed is a foreign matter crusher in a steel pipe that can be easily inserted from an elongated groove of a water-impervious plate and can crush lumps such as earth and sand, honeycombs, and dust that have hardened inside the steel pipe.

この鋼管内異物粉砕機は、長さが異なり湾曲した一対の板バネからなる治具部と弾性に富む金属製のチューブを接合し、ガイドパイプにチューブを通して突き出し、チューブ端部に取り付けた駆動部から回転力を与えることで、鋼管内の土砂、蜂の巣およびごみ等の固まりを粉砕する構造とされている。 This foreign matter crusher in a steel pipe joins a jig part consisting of a pair of leaf springs of different lengths and curves and a metal tube with high elasticity, projects the tube through the guide pipe, and attaches it to the end of the tube. It has a structure that crushes lumps of earth and sand, honeycombs, dust, etc. in the steel pipe by applying a rotational force from the pipe.

実用新案登録第3056395号公報Utility Model Registration No. 3056395 Gazette

上記した様に、電源を要する高圧洗浄機や、特許文献1に示すような電動ドリル等の各種の装置を活用した撤去作業では、装置が大掛かりとなり、且つ塔上での扱いが困難であり、適用条件が用途によって限定されていた。 As described above, in the removal work using various devices such as a high pressure washer that requires a power source and an electric drill as shown in Patent Document 1, the device becomes large and difficult to handle on the tower. The applicable conditions were limited by the application.

具体的には、フレキシブルシャフトは、適用範囲が腹材及び水平材(径:Φ89.1mm〜Φ216.3mm)に限られ、フレキシブルシャフト長が15m〜25mに限られる。 Specifically, the applicable range of the flexible shaft is limited to the abdominal material and the horizontal material (diameter: Φ89.1 mm to Φ216.3 mm), and the flexible shaft length is limited to 15 m to 25 m.

また、高圧洗浄機は、適用範囲が最下節材(径:〜Φ216.3mmまで)に限られ、延長ホース長が20mに限られる。 Further, the application range of the high pressure washer is limited to the lowest knot material (diameter: ~ Φ216.3 mm), and the extension hose length is limited to 20 m.

さらに、フレキシブルシャフトとコンプレッサとの併用では、適用範囲が腹材及び水平材(径:〜Φ216.3mmまで)に限られ、エアホース長が80mに限られる。しかも、電動工具等の機械を必要とするため、撤去費用が高額となる。 Further, when the flexible shaft and the compressor are used in combination, the applicable range is limited to the abdominal material and the horizontal material (diameter: up to Φ216.3 mm), and the air hose length is limited to 80 m. Moreover, since a machine such as a power tool is required, the removal cost is high.

この他、特許文献1の鋼管内異物粉砕機を使用して、鉄塔の斜め鋼管の内部を清掃する場合には、作業員が搭上に上って、鋼管内異物粉砕機の先端の板バネ状の治具部をガイドパイプを使って鋼管の上側開口端に差し込む作業となるため、非常に危険であり、しかも、営巣を下方に押し出すのにかなりの労力を要する。 In addition, when cleaning the inside of the diagonal steel pipe of the steel pipe using the foreign matter crusher in the steel pipe of Patent Document 1, a worker goes up on board and the leaf spring at the tip of the foreign matter crusher in the steel pipe. It is very dangerous because the work of inserting the shaped jig part into the upper opening end of the steel pipe using a guide pipe, and moreover, it takes a considerable amount of labor to push the nesting downward.

また、既存の営巣撤去工法は、上記した大掛かりな装置を用いることから、鋼管内部腐食点検(以下、内視鏡点検とする。)時、鋼管内に営巣を発見しても、その都度、営巣を撤去することが困難である。 In addition, since the existing nesting removal method uses the above-mentioned large-scale equipment, even if a nest is found in the steel pipe during a steel pipe internal corrosion inspection (hereinafter referred to as endoscopic inspection), nesting is performed each time. Is difficult to remove.

そのため、別工事で営巣を撤去した上で、再度、内視鏡点検による調査を実施することから、費用が嵩んでいた。 Therefore, after removing the nesting by another construction, the investigation by endoscopic inspection is carried out again, which increases the cost.

この様に、従来技術においては、内視鏡点検に合わせた営巣撤去を実施することができない事態が生じていた。 As described above, in the prior art, there has been a situation in which it is not possible to remove the nest in accordance with the endoscopic inspection.

また、既存の営巣撤去工法は、電源を要する高圧洗浄機や特許文献1に示すような電動ドリル等を活用した大掛かりな装置を用いるため、資機材が重量物となり、搬出入も困難である。 Further, since the existing nesting removal method uses a large-scale device utilizing a high-pressure washer that requires a power source and an electric drill as shown in Patent Document 1, the materials and equipment become heavy and it is difficult to carry in and out.

更に、塔上での扱いも困難であり、また、標準的な営巣撤去工法が確立されていないため、工具を扱う技量が求められていた。 Furthermore, it is difficult to handle on the tower, and since a standard nesting removal method has not been established, skill in handling tools has been required.

そこで、営巣の発見時に、直ぐに営巣を撤去できる営巣撤去工法を確立する必要がある。また、作業員の技量に関係なく取り扱いが簡便で、しかも、営巣の撤去時に鋼管内面に付着した堆積物を確実に除去できる営巣撤去工具を開発する必要がある。 Therefore, it is necessary to establish a nest removal method that can immediately remove the nest when the nest is discovered. In addition, it is necessary to develop a nesting removal tool that is easy to handle regardless of the skill of the worker and can surely remove the deposits adhering to the inner surface of the steel pipe when the nesting is removed.

本発明は、如上のような従来存在した諸事情に鑑み創出されたもので、営巣の撤去箇所(地上側の鋼管や塔上側の鋼管等)に限定されない作業方法で、特段の技量や経験も必要とせず、また、大掛かりな工具も使用せず、地上からの簡便な作業により、例えば、鳥獣や蜂等の営巣を確実に撤去することのできる、鋼管の営巣撤去工具及び営巣撤去工法を提供することを目的とする。 The present invention was created in view of the above-mentioned conventional circumstances, and is a work method that is not limited to the location where the nest is removed (steel pipe on the ground side, steel pipe on the upper side of the tower, etc.), and has special skill and experience. We provide a nesting removal tool for steel pipes and a nesting removal method that can reliably remove nests of birds, bees, bees, etc. by simple work from the ground without the need and without using large-scale tools. The purpose is to do.
