Description

本発明は、架空送電線の保守、点検、工事の際に作業者が使用する単導体用宙乗機ローラ防護カバー(単導体用宙乗器ローラ防護カバーとも称する）に関する。 The present invention relates to a single conductor roller protective cover (also referred to as a single conductor roller protective cover) used by an operator during maintenance, inspection, and construction of an overhead power transmission line.

鉄塔等の支持物で支持されている架空送電線等の電線について、保守、点検、工事の際は、作業者が宙乗機に乗って作業するのが一般的である。 For maintenance, inspection, and construction of electric wires such as overhead power transmission lines that are supported by supports such as steel towers, it is common for workers to ride on a spacecraft.

従来の宙乗機は、特許文献１、２に記載のように、枠体で間隔を置いたフレームにローラを直列に回転可能に軸支し、フレームより腰掛板を吊下げた構造となっている。 As described in Patent Documents 1 and 2, the conventional airborne machine has a structure in which rollers are rotatably supported in series on a frame spaced by a frame, and a stool plate is suspended from the frame. There is.

宙乗機の使用においては、電線に前後のローラを乗架させて宙乗機を電線に設置する。宙乗機の腰掛板上に座した作業者が胸前に位置する電線を漕いで、宙乗機を所定位置（作業位置）に移動するものであった。 When using the airborne machine, the front and rear rollers are mounted on the electric wire to install the airborne machine on the electric wire. A worker sitting on the seat plate of the airborne machine rowed an electric wire located in front of the chest to move the airborne machine to a predetermined position (working position).

また、宙乗機には、ブレーキ装置を付けたものがあり、ブレーキシューを電線に押し当ててブレーキをかけるものもある(例えば特許文献３参照）。 In addition, some airborne machines are equipped with a braking device, and some are braked by pressing a brake shoe against an electric wire (see, for example, Patent Document 3).

従来の宙乗機では、作業者は電線に手を掛けて送り出して漕ぐ際に、架線を握る手がローラに手が触れてしまうと、宙乗機を一旦停止して電線を持ち直し再度漕ぐため作業に支障が生じる。また、ローラに手が触れるのを防止するためにブレーキ装置を掛けるとしても頻繁なブレーキの使用は手間がかかってしまう。しかながら、従来は、ローラに手が触れることを簡易な構造で防止する技術は提案されていなかった。 In a conventional airborne machine, when a worker puts his / her hand on an electric wire and sends it out to row, if the hand holding the overhead wire touches the roller, the airborne machine is temporarily stopped, the electric wire is picked up, and the electric wire is rowed again. Work will be hindered. Further, even if the brake device is applied to prevent the roller from being touched by the hand, frequent use of the brake is troublesome. However, conventionally, a technique for preventing the roller from being touched by a hand with a simple structure has not been proposed.

本発明は、斯かる実情に鑑み、作業者が宙乗機に架線に手をかけた際にローラに触れることを防止できる単導体用宙乗機ローラ防護カバーを提供しようとするものである。 In view of such circumstances, the present invention intends to provide a single conductor roller protective cover for a single conductor that can prevent an operator from touching a roller when the operator touches an overhead wire on the overhead wire.

The hanging member 22 is connected to a bracket extending below the front and rear roller frames 10a and 10b, and a seat plate 16 is connected to the lower part of the hanging member 22. The hanging member 22 of the stool plate 16 may have various structures.

〔前・後のローラ１２・１４〕
前・後のローラ１２・１４は、フレーム１０の上部に左右方向に沿って貫通して固定された回転軸２４によってフレーム１０(前・後のローラフレーム１０ａ・１０ｂ）に回転可能に設けられる。 [Front / rear rollers 12/14]
The front and rear rollers 12 and 14 are rotatably provided on the frame 10 (front and rear roller frames 10a and 10b) by a rotating shaft 24 which is fixed to the upper portion of the frame 10 so as to penetrate along the left-right direction.

前・後のローラ１２・１４は、軸方向に側部よりも中央部が小径になって線２６に乗架させた際に誘導しやすくなっている。 The front and rear rollers 12 and 14 have a smaller diameter at the center than the side in the axial direction, and are easy to guide when mounted on the wire 26.

なお、前・後のローラフレーム１０ａ・１０ｂの内部において、前・後のローラ１２・１４の下方にガイドローラ２８が設けられる。また、前・後のローラフレーム１０ａ・１０ｂの外部には、作業者が作業中に背中を支持する背当てベルト３０の両端部を連結するリング状のブラケット３２・３２がそれぞれ固定されている。 Inside the front and rear roller frames 10a and 10b, guide rollers 28 are provided below the front and rear rollers 12 and 14. Further, ring-shaped brackets 32 and 32 connecting both ends of the back support belt 30 that supports the back during work by the operator are fixed to the outside of the front and rear roller frames 10a and 10b, respectively.

前・後のローラフレーム１０ａ・１０ｂの上部には、宙乗機を搬送の際等に吊下げるためのリング状の搬送用ブラケット３４が上方に突出してそれぞれ固定されている。
〔前・後のカバー部材１８・２０〕 Ring-shaped transport brackets 34 for suspending the airborne machine during transport are projected upward and fixed to the upper portions of the front and rear roller frames 10a and 10b, respectively.
[Front / rear cover members 18/20]

前・後のカバー部材１８・２０は、図１に示すように、前・後のローラ１２・１４の各回転軸２４方向に沿う側面視で下開きのＵ字形状に概略呈している側面に空間のあるものである。 As shown in FIG. 1, the front and rear cover members 18 and 20 are arranged on the side surfaces that are roughly presented in a U-shape that opens downward in a side view along each rotation axis 24 direction of the front and rear rollers 12 and 14. There is space.

前・後のカバー部材１８・２０は、前・後のローラ１２・１４をそれぞれフレーム１０(メインフレーム１０ｃ)の長さ方向の前側及び後ろ側から覆うものであって、それぞれのカバー部材１８・２０がフレーム１０（ローラフレーム１０ａ・１０ｂ）から着脱可能になっている。したがって、前後のカバー部材１８・２０は、フレーム１０の長さ方向の前側及び後ろ側から前・後のローラ１２・１４を覆うことから、宙乗機に乗った作業者が移動のため線２６を掴んで漕ぐ際に、前・後のカバー部材１８・２０が手に当たるので作業者は前・後のローラ１２・１４に手が当たることを防止できる。 The front and rear cover members 18 and 20 cover the front and rear rollers 12 and 14 from the front side and the rear side in the length direction of the frame 10 (main frame 10c), respectively, and the front and rear cover members 18 and 20 respectively. 20 is removable from the frame 10 (roller frames 10a and 10b). Therefore, since the front and rear cover members 18 and 20 cover the front and rear rollers 12 and 14 from the front side and the rear side in the length direction of the frame 10, the line 26 is moved by the operator on the airborne machine. Since the front and rear cover members 18 and 20 hit the hands when rowing, the operator can prevent the front and rear rollers 12 and 14 from hitting the hands.

ここで、部品図として、図２は前のカバー部材１８を示し、図３は後のカバー部材２０を示す。図２、図３において、前方を符号Ｆ、後方を符号Ｂ、右側を符号Ｒ、左側を符号Ｌによってそれぞれ示している。図４は取付プレート３８を示し、図５は接触検知部３６を示している。 Here, as a component diagram, FIG. 2 shows the front cover member 18, and FIG. 3 shows the rear cover member 20. In FIGS. 2 and 3, the front part is indicated by the symbol F, the rear part is indicated by the reference numeral B, the right side is indicated by the reference numeral R, and the left side is indicated by the reference numeral L. FIG. 4 shows the mounting plate 38, and FIG. 5 shows the contact detection unit 36.

〔前のカバー部材１８〕
詳しくは、前のカバー部材１８は、図２に示すように、前のローラ１２（図１参照）を上から覆う天板から前・後から覆う前後板までの外板部１８ａが側面視でＵ字形状に折り曲げられて形成されている。前のローラ１２の両側部に対向する側板部１８ｂが外板部１８ａの両側に壁状に形成されている。 [Front cover member 18]
Specifically, as shown in FIG. 2, the front cover member 18 has an outer plate portion 18a from the top plate covering the front roller 12 (see FIG. 1) from above to the front and rear plates covering from the front and rear in a side view. It is formed by being bent into a U shape. Side plate portions 18b facing both side portions of the front roller 12 are formed in a wall shape on both sides of the outer plate portion 18a.

実施形態では、側板部１８ｂの取り囲む空間１８ｂｕは、図２（ｃ）に示すように全体的に側面視で下開きのＵ字形状に概略呈している。空間１８ｂｕは、前のローラ１２とほぼ同じ大きさになるように大きく抉れている。したがって、このような側面の空間１８ｂｕがあるので、この空間１８ｂｕを通して前のローラ１２の側面から前のカバー部材１８の内部に手を入れやすくなっており、取付プレート３８を取り付ける際にアクセスしやすい構造である。また、側板部１８ｂは外板部１８ａと共に断面コ字形状を呈して、外板部１８ａを補強する機能も有する。 In the embodiment, the space 18bu surrounded by the side plate portion 18b is roughly presented in a U-shape that opens downward as a whole as shown in FIG. 2 (c). The space 18bu is largely scooped out to be approximately the same size as the previous roller 12. Therefore, since there is such a side space 18bu, it is easy to reach the inside of the front cover member 18 from the side surface of the front roller 12 through this space 18bu, and it is easy to access when mounting the mounting plate 38. It is a structure. Further, the side plate portion 18b has a U-shaped cross section together with the outer plate portion 18a, and has a function of reinforcing the outer plate portion 18a.

なお、本発明において、カバー部材の構造は、種々に構成でき、側板部の大きさは種々に設定して、前のローラ１２の側面にラップしなくても、部分的又は全面的に覆うこともでき、さらには、側板部自体を設けない構造とすることも種々にできる。 In the present invention, the structure of the cover member can be variously configured, and the size of the side plate portion can be set variously to partially or completely cover the cover member without wrapping it on the side surface of the front roller 12. Further, it is possible to make various structures in which the side plate portion itself is not provided.

また、図２に（ｂ）、（ｃ）に示すように、両側板部１８ｂのうちで前方Ｆに対して左側１８ｂＬは全体に形成され、右側１８ｂＲは後部が切り欠き１８ｃが空間１８ｂｕに連続している。この切り欠き１８ｃは、フレーム１０のメインフレーム１０ｃ（図１参照）が干渉しないように逃がすことができる。 Further, as shown in FIGS. 2B and 2C, the left side 18bL of the side plate portions 18b with respect to the front F is formed as a whole, and the right side 18bR has a notch at the rear portion and the rear portion 18c is continuous with the space 18bu. doing. The notch 18c can be escaped so that the main frame 10c (see FIG. 1) of the frame 10 does not interfere with each other.

また、前のカバー部材１８は、その前方の下端部の左右に、後記する接触検知部３６固定用の環状の取り付け部１８ｄが固定されている。取付け部１８ｄは、対（２つ）で形成されているので、接触検知部３６を何れかの取り付け部１８ｄに選択して取り付け、又は、別の部材を取り付けることができる。 Further, the front cover member 18 has an annular attachment portion 18d for fixing the contact detection portion 36, which will be described later, fixed to the left and right of the lower end portion in front of the cover member 18. Since the attachment portions 18d are formed in pairs (two), the contact detection portion 36 can be selected and attached to any of the attachment portions 18d, or another member can be attached.

外板部１８ａの上部には、前のカバー部材１８をフレームの搬送用ブラケット３４を通す挿通孔１８ｅと取付け穴１８ｆ、１８ｆが形成されている。図１に示すように、挿通孔１８ｅにブラケット３４を通して、前のカバー部材１８をローラフレーム１０ａに設置し、そして、ローラフレーム１０ａを下方から挟み付けるように取付プレート３８を設置し、上方から取付け穴１８ｆ、１８ｆにボルトを通して前のカバー部材１８を取付プレート３８にボルト止めし、前のカバー部材１８をローラフレーム１０ａに固定する。 An insertion hole 18e through which the front cover member 18 is passed through the frame transport bracket 34 and mounting holes 18f and 18f are formed on the upper portion of the outer plate portion 18a. As shown in FIG. 1, the front cover member 18 is installed on the roller frame 10a through the bracket 34 through the insertion hole 18e, and the mounting plate 38 is installed so as to sandwich the roller frame 10a from below, and is mounted from above. The front cover member 18 is bolted to the mounting plate 38 by passing bolts through the holes 18f and 18f, and the front cover member 18 is fixed to the roller frame 10a.

前のカバー部材１８は、図１に示すように、上方から前のローラ１２を完全に覆い、かつ、前・後方向視で前のローラ１２に重なる構造を有する。 As shown in FIG. 1, the front cover member 18 has a structure that completely covers the front roller 12 from above and overlaps the front roller 12 in the front and rear directions.

具体的には、宙乗機を線２６に設置した場合に、図１に示すように、前のカバー部材１８は下部の下縁１８ａｕが、前・後方向視で前のローラ１２の下縁に沿う形状を呈し、かつ、側方向視で線２６に重なるように延在したものである。実施形態では、図１、図２に示すように、前のカバー部材１８は、下部の下縁１８ａｕが下開きの半円形状を呈し、前のローラ１２の下縁形状が同様に下開きの半円形状を呈している。前のカバー部材１８における下縁１８ａｕの位置は前のローラ１２の下縁位置に対して上方に位置して線２６に干渉しにくい構造になっている。 Specifically, when the airborne machine is installed on the line 26, as shown in FIG. 1, the lower lower edge 18au of the front cover member 18 is the lower edge of the front roller 12 in the front and rear directions. It has a shape along the line 26 and extends so as to overlap the line 26 in a lateral view. In the embodiment, as shown in FIGS. 1 and 2, the front cover member 18 has a semicircular shape in which the lower lower edge 18au opens downward, and the lower edge shape of the front roller 12 also opens downward. It has a semicircular shape. The position of the lower edge 18au on the front cover member 18 is located above the lower edge position of the front roller 12, and has a structure that does not easily interfere with the line 26.

〔後のカバー部材２０〕
詳しくは、後のカバー部材２０は、図３に示すように、後のローラ１４（図１参照）を上から覆う天板から前・後から覆う前後板までの外板部２０ａが側面視でＵ字形状に折り曲げられて形成されている。後のローラ１４の両側部に対向する側板部２０ｂが外板部２０ａの両側に壁状に形成されている。 [Rear cover member 20]
Specifically, as shown in FIG. 3, in the rear cover member 20, the outer plate portion 20a from the top plate covering the rear roller 14 (see FIG. 1) from above to the front and rear plates covering from the front and rear is viewed from the side. It is formed by being bent into a U shape. Side plate portions 20b facing both side portions of the rear roller 14 are formed in a wall shape on both sides of the outer plate portion 20a.

実施形態では、側板部２０ｂの取り囲む空間２０ｂｕは、図３（ｃ）に示すように全体的に側面視で下開きのＵ字形状に概略呈している。空間２０ｂｕは、後のローラ１４とほぼ同じ大きさになるように大きく抉れている。したがって、このような側面の空間２０ｂｕがあるので、この空間２０ｂｕを通して後のローラ１４の側面から後のカバー部材２０の内部に手を入れやすくなっており、取付プレート３８（図１参照）を取り付ける際にアクセスしやすい構造である。また、側板部２０ｂは外板部２０ａと共に断面コ字形状を呈して、外板部２０ａを補強する機能も有する。 In the embodiment, the space 20bu surrounded by the side plate portion 20b is roughly presented in a U-shape that opens downward as a whole as shown in FIG. 3C. The space 20bu is largely scooped out so as to be approximately the same size as the later roller 14. Therefore, since there is such a side space 20bu, it is easy to put a hand from the side surface of the rear roller 14 to the inside of the rear cover member 20 through this space 20bu, and the mounting plate 38 (see FIG. 1) is mounted. The structure is easy to access. Further, the side plate portion 20b has a U-shaped cross section together with the outer plate portion 20a, and has a function of reinforcing the outer plate portion 20a.

なお、本発明において、後のカバー部材２０の構造は、種々に構成でき、側板部の大きさは種々に設定して、後のローラ１４の側面にラップしなくても、部分的又は全面的に覆うこともでき、さらには、側板部自体を設けない構造とすることも種々にできる。 In the present invention, the structure of the rear cover member 20 can be variously configured, the size of the side plate portion can be set variously, and the rear cover member 20 can be partially or completely without being wrapped around the side surface of the rear roller 14. Further, it is possible to have a structure in which the side plate portion itself is not provided.

図３に（ｂ）、（ｃ）に示すように、両側板部２０ｂのうちで前方Ｆに対して左側２０ｂＬは全体に形成され、右側２０ｂＲは前部が切り欠かれて空間２０ｃになっている。この空間２０ｃは、フレーム１０のメインフレーム１０ｃ（図１参照）が干渉しないように逃がすことができる。 As shown in FIGS. 3B and 3C, of the side plate portions 20b, the left side 20bL is formed as a whole with respect to the front F, and the right side 20bR is a space 20c with the front portion cut out. There is. This space 20c can be escaped so that the main frame 10c (see FIG. 1) of the frame 10 does not interfere with each other.

また、後のカバー部材２０は、その後部の下端部の右側に、後記する接触検知部３６固定用の環状の取り付け部２０ｄが固定されている。取付け部２０ｄは、後のカバー部材２０の右側に１つが形成されている。反対の左側に取付け部２０ｄの形成されていないが、これは後述するブレーキ装置４０のレバー部材４０ａに干渉しないようになっている。 Further, in the rear cover member 20, an annular attachment portion 20d for fixing the contact detection portion 36, which will be described later, is fixed to the right side of the lower end portion of the rear portion. One mounting portion 20d is formed on the right side of the rear cover member 20. Although the mounting portion 20d is not formed on the opposite left side, it does not interfere with the lever member 40a of the brake device 40 described later.

外板部２０ａの上部には、後のカバー部材２０をフレームの搬送用ブラケット３４を通す挿通孔２０ｅと取付け穴２０ｆ、２０ｆが形成されている。図１に示すように、挿通孔２０ｅにブラケット３４を通して、後のカバー部材２０をローラフレーム１０ａに設置し、そして、ローラフレーム１０ａを下方から挟み付けるように取付プレート３８を設置し、上方から取付け穴２０ｆ、２０ｆにボルトを通して後のカバー部材２０を取付プレート３８によってボルト止めする。 An insertion hole 20e and mounting holes 20f and 20f through which the rear cover member 20 is passed through the frame transport bracket 34 are formed in the upper portion of the outer plate portion 20a. As shown in FIG. 1, the bracket 34 is passed through the insertion hole 20e, the rear cover member 20 is installed on the roller frame 10a, and the mounting plate 38 is installed so as to sandwich the roller frame 10a from below, and is mounted from above. A bolt is passed through the holes 20f and 20f, and the rear cover member 20 is bolted by the mounting plate 38.

後のカバー部材２０は、図１に示すように、前のローラ１２と前のカバー部材１８の関係と同様に、上方から後のローラ１４を完全に覆い、かつ、前・後方向視で後のローラ１４に重なる構造を有する。具体的には、前記宙乗機を線２６に設置した場合に、後のカバー部材２０は下部の下縁が、前・後方向視で後のローラ１４の下縁に沿う形状を呈し、かつ、側方向視で線２６に重なるように延在したものである。後のカバー部材２０は、下部の下縁２０ｂｕが下開きの半円形状を呈し、後のローラ１４の下縁形状が同様に下開きの半円形状を呈している。後のカバー部材２０の下縁位置は後のローラ１４の下縁位置に対して上方に位置して線２６に干渉しにくい構造になっている。 As shown in FIG. 1, the rear cover member 20 completely covers the rear roller 14 from above, and rearward in front and rear directions, similar to the relationship between the front roller 12 and the front cover member 18. It has a structure that overlaps with the roller 14. Specifically, when the airborne machine is installed on the line 26, the lower edge of the lower part of the rear cover member 20 exhibits a shape along the lower edge of the rear roller 14 in the front and rear directions. , It extends so as to overlap the line 26 in the lateral view. In the rear cover member 20, the lower lower edge 20bu has a semicircular shape that opens downward, and the lower edge shape of the rear roller 14 also has a semicircular shape that opens downward. The lower edge position of the rear cover member 20 is located above the lower edge position of the rear roller 14, and has a structure that does not easily interfere with the line 26.

なお、前・後のカバー部材１８・２０は、前記前・後のローラ１２・１４をそれぞれ長さ方向の前側及び後ろ側から覆うものであるので、作業者が線２６を持って漕いで移動する際にそれぞれがフレームから着脱可能になっている。 Since the front and rear cover members 18 and 20 cover the front and rear rollers 12 and 14 from the front side and the rear side in the length direction, respectively, the operator can row and move with the line 26. Each is removable from the frame when doing so.

〔取付プレート３８〕
取付プレート３８は、図４に示すように、概略平板状であり、前・後のカバー部材１８・２０をフレーム１０（ローラフレーム１０ａ）（図１参照）に取り付けるための金属材からなる部材である。 [Mounting plate 38]
As shown in FIG. 4, the mounting plate 38 has a substantially flat plate shape, and is a member made of a metal material for mounting the front and rear cover members 18 and 20 to the frame 10 (roller frame 10a) (see FIG. 1). is there.

取付プレート３８は、中央部３８ａが両端部３８ｂ・３８ｂに比較して段部３８ａ１・３８ａ１から下方に向けて凹むように曲がっている。取付プレート３８は、両端部３８ｂ・３８ｂに、下面にナット３８ｃ・３８ｃが溶接固定されている。 The mounting plate 38 is bent so that the central portion 38a is recessed downward from the step portions 38a1 and 38a1 as compared with the both end portions 38b and 38b. The mounting plate 38 has nuts 38c and 38c welded and fixed to both ends 38b and 38b on the lower surface.

前・後のカバー部材１８・２０をフレーム１０に取付けるに際には、まず、上方から前・後のカバー部材１８・２０を前・後のローラ１２・１４に被せる。挿通孔１８ｅ・２０ｅに搬送用ブラケット３４・３４に通して、前・後のカバー部材１８・２０の下面をローラフレーム１０ａ・１０ａの上部に対向・当接させる。その後、ローラフレーム１０ａ・１０ａの上部の下面側に取付プレート３８・３８の中央部３８ａ・３８ａの凹みを嵌め込んで取付プレート３８・３８を位置させる。そして、おのおの上方から取付け穴１８ｆ、２０ｆにボルトを通してナット３８ｃ・３８ｃに螺合させて締め付け、カバー部材１８・２０を取付プレート３８にボルト止めする。 When attaching the front and rear cover members 18 and 20 to the frame 10, first, the front and rear cover members 18 and 20 are covered on the front and rear rollers 12 and 14 from above. The transport brackets 34 and 34 are passed through the insertion holes 18e and 20e so that the lower surfaces of the front and rear cover members 18 and 20 face and abut against the upper portions of the roller frames 10a and 10a. After that, the recesses of the central portions 38a and 38a of the mounting plates 38 and 38 are fitted on the lower surface side of the upper portion of the roller frames 10a and 10a to position the mounting plates 38 and 38. Then, bolts are passed through the mounting holes 18f and 20f from above, respectively, and screwed into the nuts 38c and 38c to tighten them, and the cover members 18 and 20 are bolted to the mounting plate 38.

前・後のカバー部材１８・２０はフレーム１０に対してボルト止めするので着脱が容易である。 The front and rear cover members 18 and 20 are bolted to the frame 10 so that they can be easily attached and detached.

〔接触検知部３６〕
図１に示すように、作業者が移動の際に線２６を握った手が前・後のカバー部材１８・２０に近接したことを接触によって検知させる接触検知部３６を設けている。接触検知部３６は、前・後のローラ１２・１４に設けた前・後のカバー部材１８・２０にそれぞれ前・後に突出して取付けられている。 [Contact detection unit 36]
As shown in FIG. 1, a contact detection unit 36 is provided to detect by contact that the hand holding the line 26 is close to the front and rear cover members 18 and 20 when the operator is moving. The contact detection unit 36 is attached to the front and rear cover members 18 and 20, which are provided on the front and rear rollers 12 and 14, so as to project forward and rear, respectively.

図５は、接触検知部３６の部品図である。図５に示すように、長円形の長穴３６ａの開いた、全体が角の丸い長方形の金属製のブラケット体３６ｂと、コイルバネからなる円筒形状で撓み可能な弾性検知体３６ｃと、ブラケット体３６ｂの弾性検知体３６ｃを取り付けるための取り付け用リブ３６ｄと、弾性検知体３６ｃをリブ３６ｄに取り付けるためのネジ３６ｅとを有している。 FIG. 5 is a component diagram of the contact detection unit 36. As shown in FIG. 5, a rectangular metal bracket body 36b having an oval slotted hole 36a and rounded corners as a whole, a cylindrical elastic detector body 36c made of a coil spring, and a bracket body 36b. It has an attachment rib 36d for attaching the elasticity detector 36c of the above, and a screw 36e for attaching the elasticity detector 36c to the rib 36d.

実施形態の宙乗機においては、接触検知部３６を設けているので、作業者が腰を掛けて移動する際に線２６を握った状態で前・後のカバー部材１８・２０に近接した場合、カバー部材１８・２０に手が当たるより前に弾性検知体３６ｃに手が触れることを手の触覚で認識できる。したがって、接触検知部３６によって、作業者は手がカバー部材１８・２０に近づいたことを明確に認識できる。 In the airborne machine of the embodiment, since the contact detection unit 36 is provided, when the operator approaches the front and rear cover members 18 and 20 while holding the line 26 when moving while sitting down. The touch of the elastic detector 36c before the cover members 18 and 20 are touched can be recognized by the tactile sense of the hand. Therefore, the contact detection unit 36 allows the operator to clearly recognize that the hand has approached the cover members 18 and 20.

ここで、実施形態の宙乗機では、カバー部材１８・２０によって前・後のローラ１２・１４に手が触れることを防止している。仮に、宙乗機に乗った作業者が勢いよく移動した場合に、カバー部材１８・２０の曲がりやその下方への潜り込みが生じたときに前・後のローラ１２・１４への近接が考えられるが、接触検知部３６を設けているためカバー部材１８・２０に触れるより前に作業者は前・後のローラ１２・１４及びカバー部材１８・２０への近接を認識できるので、移動を停止するなど接触防止の対策を容易にとることができる。 Here, in the airborne machine of the embodiment, the cover members 18 and 20 prevent the front and rear rollers 12 and 14 from being touched by the hands. If the worker on the airborne machine moves vigorously, the cover members 18 and 20 may bend or slip below the cover members 18 and 20, and the front and rear rollers 12 and 14 may be approached. However, since the contact detection unit 36 is provided, the operator can recognize the proximity of the front and rear rollers 12 and 14 and the cover members 18 and 20 before touching the cover members 18 and 20, so that the movement is stopped. It is possible to easily take measures to prevent contact.

接触検知部３６は、撓み可能な弾性材のコイルスプリングによって弾性検知体３６ｃを構成しているが、その他、接触検知部３６は、全体又は一部を弾性材で構成することができる。弾性材としてコイル構造以外の板状のスプリングや、樹脂を材質としたもの等種々に構成できる。 The contact detection unit 36 is formed of the elastic detection body 36c by a coil spring made of a flexible elastic material, but the contact detection unit 36 can be made of an elastic material in whole or in part. As the elastic material, various configurations such as a plate-shaped spring other than the coil structure and a material made of resin can be used.

〔ブレーキ装置４０〕
宙乗機には、図１に示すように、レバー部材４０ａの操作によって宙乗機の線２６に対する移動を規制するブレーキ装置４０を有する。ブレーキ装置４０のレバー部材４０ａは、接触検知部３６の取り付け箇所(実施形態で右Ｒ側）と平面視で線２６を挟んで反対側(実施形態で左Ｌ側）に設けられている。 [Brake device 40]
As shown in FIG. 1, the airborne aircraft includes a brake device 40 that regulates the movement of the airborne aircraft with respect to the line 26 by operating the lever member 40a. The lever member 40a of the brake device 40 is provided on the opposite side (left L side in the embodiment) of the contact detection unit 36 (right R side in the embodiment) and the line 26 in a plan view.

ブレーキ装置４０は、図１に示すように、後のローラ１４の回転軸２４にレバー部材４０ａの支点の基端４０ａ１が回転可能に軸支される。レバー部材４０ａの力点の先端４０ａ２に、図示しないロープが連結され、作業者がロープによってレバー部材４０ａを回動操作可能な構造になっている。レバー部材４０ａは、摩擦材を備えたブレーキシュー４０ｂを上下動させるリンク機構４０ｃが連結される。 In the brake device 40, as shown in FIG. 1, the base end 40a1 of the fulcrum of the lever member 40a is rotatably supported on the rotating shaft 24 of the rear roller 14. A rope (not shown) is connected to the tip 40a2 of the point of effort of the lever member 40a, so that the operator can rotate the lever member 40a with the rope. The lever member 40a is connected to a link mechanism 40c that moves the brake shoe 40b provided with the friction material up and down.

なお、リンク機構４０ｃには、レバー部材４０ａを上方に、かつ、ブレーキシュー４０ｂを下方に付勢するスプリング４０ｄがローラフレーム１０ｂとリンク機構４０ｃとの間に連結され、スプリング４０ｄの作用によって、レバー部材４０ａの非操作時には、ブレーキが開放した状態になる。
〔フレーム１０〕 A spring 40d for urging the lever member 40a upward and the brake shoe 40b downward is connected to the link mechanism 40c between the roller frame 10b and the link mechanism 40c, and the lever is acted by the action of the spring 40d. When the member 40a is not operated, the brake is released.
[Frame 10]

前記フレームは、図１に示すように、前・後のローラ１２・１４をそれぞれ回転可能に支持する前・後のローラフレーム１０ａ・１０ｂと、前・後のローラフレーム１０ａ・１０ｂ同士を前後に間隔を置いて固定するメインフレーム１０ｃを有する。ローラフレーム１０ａ・１０ｂには、背当てベルト３０の両端が連結されている。背当てベルト３０は長さが調整可能である。 As shown in FIG. 1, the frame includes front and rear roller frames 10a and 10b that rotatably support front and rear rollers 12 and 14, respectively, and front and rear roller frames 10a and 10b in the front-rear direction. It has a main frame 10c that is fixed at intervals. Both ends of the backrest belt 30 are connected to the roller frames 10a and 10b. The length of the backrest belt 30 is adjustable.

作業者がメインフレーム１０ｃの反対側から線２６と背当てベルト３０との間に位置して、足をメインフレーム１０ｃ側に下ろし、乗車する。作業者は背当てベルト３０の長さを調整した状態で背中側を適切に保持して腰掛板１６に腰を掛けて安定した作業姿勢になる。 An operator is located between the line 26 and the backrest belt 30 from the opposite side of the main frame 10c, lowers his / her foot toward the main frame 10c, and gets on the vehicle. The worker properly holds the back side in a state where the length of the backrest belt 30 is adjusted, and sits on the stool plate 16 to obtain a stable working posture.

図１（ａ）が示すように、ローラフレーム１０ａ・１０ｂに対して平面視で線２６に対するメインフレーム１０ｃの固定側と同じ側に接触検知部３６・３６が配置されている。 As shown in FIG. 1A, contact detection units 36 and 36 are arranged on the same side as the fixed side of the main frame 10c with respect to the line 26 in a plan view with respect to the roller frames 10a and 10b.

宙乗機は、レバー部材４０ａの操作によって宙乗機の線２６に対する移動を規制するブレーキ装置４０を有するが、図１（ａ）、（ｃ）に示すように、ブレーキ装置４０において、レバー部材４０ａは、接触検知部３６・３６の取り付け箇所(実施形態で右Ｒ側）と平面視で線２６を挟んで反対側に設けられている。 The airborne machine has a brake device 40 that regulates the movement of the airborne machine with respect to the line 26 by operating the lever member 40a. As shown in FIGS. 1A and 1C, in the brake device 40, the lever member The 40a is provided on the opposite side of the line 26 from the attachment location (right R side in the embodiment) of the contact detection units 36 and 36 in a plan view.

〔宙乗機の使用〕
図６は、宙乗機の使用の際の、ブレーキ装置の操作説明図である。 [Use of airborne aircraft]
FIG. 6 is an operation explanatory view of the brake device when using the airborne machine.

図６において、作業者は背当てベルト３０の長さを調整した状態で背中側を適切に保持して腰掛板１６に腰を掛けて安定した作業姿勢になる。 In FIG. 6, the worker appropriately holds the back side in a state where the length of the backrest belt 30 is adjusted, and sits on the stool plate 16 to obtain a stable working posture.

図６において、二点鎖線によってレバー部材４０ａの非操作状態を示している。ブレーキ装置４０の操作時にレバー部材４０ａを下方(符号Ｄ方向）に押し下げたときに、ブレーキシュー４０ｂが上昇して（符号Ｕ方向）線２６に押し当たり、摩擦力によって宙乗機の移動を規制する。なお、レバー部材４０ａには、ロープ等の操作用の線条体の一端が繋がり、他端がフレーム１０に繋がっており、線条体を作業者が踏む等することによってレバー部材４０ａが下がり、ブレーキがかかる構造である。 In FIG. 6, the non-operated state of the lever member 40a is shown by the alternate long and short dash line. When the lever member 40a is pushed down (in the direction of reference numeral D) when the brake device 40 is operated, the brake shoe 40b rises and hits the line 26 (in the direction of reference numeral U), and the movement of the airborne machine is restricted by the frictional force. To do. One end of a striatum for operating a rope or the like is connected to the lever member 40a, and the other end is connected to the frame 10. When an operator steps on the striatum, the lever member 40a is lowered. It is a structure that applies a brake.

作業時において、宙乗機に腰掛板１６に乗った状態の作業者は、前・後方向の何れかに移動する際に、線２６を掴んで送り出して行う。 At the time of work, the worker who is on the stool plate 16 on the airborne machine grabs the line 26 and sends it out when moving to either the front or the rear direction.

実施形態の単導体用宙乗機ローラ防護カバーによれば、前のローラ１２を少なくとも長さ方向の前側から覆い、後のローラ１４を少なくとも長さ方向の後側から覆う前・後のカバー部材１８・２０を備えているので、宙乗機に乗った作業者が線２６を持ったときにカバー部材１８・２０によって作業者がローラ１２・１４に接触することを防止できる。 According to the single conductor roller protective cover of the embodiment, the front and rear cover members cover the front roller 12 from at least the front side in the length direction and the rear roller 14 from at least the rear side in the length direction. Since the 18 and 20 are provided, it is possible to prevent the operator from coming into contact with the rollers 12 and 14 by the cover members 18 and 20 when the operator on the airborne machine holds the wire 26.

また、接触検知部３６に手が接触することによって作業者は、手が前・後のカバー部材１８・２０に近づいたことを知ることができる。前方から手が前の接触検知部３６に接触したとき、また、後方から手が後の接触検知部３６に接触したときに、作業者用がそれぞれ検知できる。 Further, when the hand comes into contact with the contact detection unit 36, the operator can know that the hand has approached the front / rear cover members 18 and 20. When the hand comes into contact with the front contact detection unit 36 from the front, and when the hand comes into contact with the rear contact detection unit 36 from the rear, the operator can detect each.

実施形態は本発明の一例であり、種々に変形実施できる。第１実施形態では線２６として例えばＡＣＳＲ（鋼心アルミ撚線）であって３３０ｍｍ^２〜６１０ｍｍ^２用(呼びのもの）である。前・後のローラ１２・１４は寸法が同じであり、ローラ１２・１４の最小部、フランジ外径、ローラの内周面径が、ローラ１２・１４の軸方向の厚さや、前・後カバー部材１８・２０の縦、幅、高さ、取付プレート寸法等は、ローラが覆えるカバーであれば寸法は種々に選択できる。例えばローラ１２・１４の外径が１２５ｍｍ、カバー部材１８・２０がほぼ長さ１５０〜１７０ｍｍ程度に設定できる。 The embodiment is an example of the present invention, and various modifications can be made. In the first embodiment, for example ACSR by a line 26 for 330mm ^² ~610mm ² a (steel core aluminum stranded wire) (referred ones). The front and rear rollers 12 and 14 have the same dimensions, and the minimum part of the rollers 12 and 14, the outer diameter of the flange, and the inner peripheral surface diameter of the rollers are the thickness of the rollers 12 and 14 in the axial direction and the front and rear covers. The length, width, height, mounting plate dimensions, etc. of the members 18 and 20 can be variously selected as long as the cover can be covered by the rollers. For example, the outer diameters of the rollers 12 and 14 can be set to 125 mm, and the lengths of the cover members 18 and 20 can be set to about 150 to 170 mm.

第２実施形態では、宙乗機を適用する線２６の太さが第１実施形態と異なり、それに使用する前・後のローラ１２・１４も大きさが異なるものである。図７は、第２実施形態に係る宙乗機の説明図、図８、図９に前・後のカバー部材１８・２０である。なお、各部については、第１実施形態と同様部分に同一符号を付している。 In the second embodiment, the thickness of the line 26 to which the airborne machine is applied is different from that of the first embodiment, and the front and rear rollers 12 and 14 used for the line 26 are also different in size. 7 is an explanatory view of the airborne machine according to the second embodiment, and FIGS. 8 and 9 show front and rear cover members 18 and 20. As for each part, the same reference numerals are given to the same parts as in the first embodiment.

第２実施形態では線２６として例えばＡＣＳＲ（鋼心アルミ撚線）であるが、１００ｍｍ^２〜４１０ｍｍ^２用のものである。ローラが覆えるカバーであれば寸法は種々に選択できる。例えばローラ１２・１４の外径が１００ｍｍ、カバー部材１８・２０がほぼ長さ１３０〜１５０ｍｍ程度に設定できる。 Although the second embodiment is ACSR for example, a line 26 (steel core aluminum stranded ^wire), is for a 100mm ² ~410mm 2. Various dimensions can be selected as long as the cover can be covered by the rollers. For example, the outer diameters of the rollers 12 and 14 can be set to 100 mm, and the lengths of the cover members 18 and 20 can be set to about 130 to 150 mm.

なお、宙乗機を適用する線２６は種々に選択することができるが、線の太さが変われば宙乗機もそのローラ防護カバーも異なる実施形態を適用することができる。第１実施形態や第２実施形態を適用する線の太さと異なる太さの線について対応させた宙乗機ローラ防護カバーの他の実施形態を図１０、図１１によって説明する。図１０は、第３実施形態に係る単導体用宙乗機ローラ防護カバー、図１１は、第４実施形態に係る単導体用宙乗機ローラ防護カバーである。 The line 26 to which the airborne machine is applied can be selected in various ways, but if the thickness of the line is changed, different embodiments can be applied to the airborne machine and its roller protective cover. Other embodiments of the airborne roller protective cover corresponding to lines having a thickness different from the line thickness to which the first embodiment and the second embodiment are applied will be described with reference to FIGS. 10 and 11.
