Description

本発明は、足場装置に関し、具体的には、架空設備に対する作業の際に当該架空設備に懸架される足場装置に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffolding device, and more particularly to a scaffolding device that is suspended from an overhead facility during work on that facility.

互いに離間して配置されている支柱と、これらの支柱間に掛け渡された架空物とによって構成される架空設備として、上記支柱に相当する鉄塔や電柱(以下、単に「鉄塔」と記載する。)と、鉄塔間に掛け渡された上記架空物に相当する送電線とを含む送電線設備を挙げることができる。送電線には、電気を送電するための電線、電線を落雷などから保護するために鉄塔の例えば頂部間に掛け渡される架空地線、及びその他これらに類するものが含まれる。このような送電線設備においては、作業者が鉄塔に上ってジャンパ線を接続したり開放したりするジャンパ作業等の送電線の補修、保守、及び点検等の諸作業(以下、「送電線作業」という。)が行われることがある。このような送電線作業の作業者は、鉄塔から送電線に乗り出して、送電線における作業箇所まで移動する必要がある。 Steel towers and utility poles (hereinafter simply referred to as "pylons") corresponding to the above-mentioned pillars are overhead facilities composed of pillars spaced apart from each other and aerial objects suspended between these pillars. ) and a power transmission line corresponding to the above-mentioned overhead object stretched between steel towers. Transmission lines include wires for transmitting electricity, overhead ground wires strung between, for example, the tops of pylons to protect the wires from lightning strikes and the like, and the like. In such transmission line facilities, various operations such as repair, maintenance, and inspection of transmission lines such as jumper work in which workers climb the tower and connect and disconnect jumper wires (hereinafter referred to as "transmission line work”) may be performed. A worker for such power transmission line work needs to climb onto the power transmission line from the steel tower and move to a work location on the power transmission line.

そこで、このような移動を容易にしたり作業箇所の足場を確保したりするために、鉄塔から送電線の所望の位置までに、足場が梯子状に構成された足場装置を懸架することがある(例えば、特許文献1参照)。 Therefore, in order to facilitate such movement and secure a scaffolding at the work site, a scaffolding device with a ladder-like scaffolding is sometimes suspended from the steel tower to the desired position of the transmission line ( For example, see Patent Document 1).

特開2010-090667号公報JP 2010-090667 A

ところで、このような足場装置では、概して足場が装置の大部分を占め、かつ、足場の重量は足場装置全体の重量と概ね等しい。上記特許文献1に記載された足場装置の足場は梯子状であるため、大きくなり易く、また、足場を構成する部材も増加する。そのため、足場装置全体が嵩張りかつ重くなる。例えば、全長3.0mのJIS規格鋼材からなる梯子状の足場を備える足場装置の重量は、20kg程度になる。このような足場装置を鉄塔と送電線との間に懸架するためには体力や技能が必要となる。そこで、取り扱いが容易な足場装置が求められている。 By the way, in such a scaffolding device, the scaffolding generally occupies the majority of the device, and the weight of the scaffolding is approximately equal to the weight of the entire scaffolding device. Since the scaffolding of the scaffolding device described in Patent Document 1 is ladder-shaped, it tends to be large and the number of members constituting the scaffolding is increased. Therefore, the entire scaffolding device becomes bulky and heavy. For example, the weight of a scaffolding device having a ladder-shaped scaffold made of JIS standard steel with a total length of 3.0 m is about 20 kg. Physical strength and skill are required to suspend such a scaffolding device between the steel tower and the transmission line. Therefore, a scaffolding device that is easy to handle is desired.

また、送電線設備以外の架空設備に対する作業においても、同様に、取り扱いが容易な足場装置が求められている。 Similarly, there is a demand for a scaffolding device that is easy to handle in work on overhead facilities other than power transmission line facilities.

次に、足場装置1の使用の一例と、その際の足場装置の作用及び効果について説明する。 Next, an example of use of the scaffolding device 1 and the action and effect of the scaffolding device at that time will be described.

上述のように及び図1に示すように、他方側取付部30は、フックからなる係合部35と、係合部35の第2の部分35bに設けられる被付着部36と、足場本体10の他端部13に設けられる付着部37(一対のマグネット37a,37b)と、他端部13と係合部35とを連結する連結部34と、を含んでいる。連結部34は、可撓性の長尺部33を有する。このような構成によれば、連結部34の長尺部33を折り畳むことによって、付着部37を被付着部36に付着させることができる。図5は、係合部35が送電線に係合した状態を示す図であり、この図5では、長尺部33が折り畳まれて付着部37が被付着部36に付着した状態が示されている。 As described above and as shown in FIG. Attachment portion 37 (a pair of magnets 37 a and 37 b ) provided at the other end portion 13 of the magnet, and connecting portion 34 connecting the other end portion 13 and engaging portion 35 . The connecting portion 34 has a flexible elongated portion 33 . According to such a configuration, the attaching portion 37 can be attached to the attaching portion 36 by folding the long portion 33 of the connecting portion 34 . FIG. 5 is a diagram showing a state in which the engaging portion 35 is engaged with the transmission line, and FIG. 5 shows a state in which the long portion 33 is folded and the attaching portion 37 is attached to the attached portion 36. ing.

上述のように、被付着部36の被付着面である主面36fは、フックが向く方向Dfと直交している。連結部34の長尺部33は可撓性を有しているため、図1の状態から係合部35を右に向けてフックが向く方向Dfを右にすることができる。この状態を保ちながら、足場本体10を軸中心に180度右回転させつつ長尺部33を上側に折り畳むと、図5に示すように、図1及び図2の状態において左側に位置していたマグネット37aを主面36fに付着させることができる。すなわち、図5の状態では、マグネット37a,37bの左右方向における位置が図1とは逆になっており、図1の状態において右側に位置していたため視認できなかったマグネット37bが左側に位置して視認できる状態になっている。このように、足場本体10が軸中心に半回転してマグネット37aが被付着部36に固定されたことによって、他端部13における連結部34が取り付けられる部位(図2における上端部13a)が下側を向き、かつ、把持部40が上側を向いた状態となる。この図5の状態では、連結部34が折り畳まれてコンパクトになっているため、足場装置1の例えば運搬が容易であり、取り扱いが容易である。 As described above, the main surface 36f, which is the adhered surface of the adhered portion 36, is orthogonal to the direction Df in which the hook faces. Since the elongated portion 33 of the connecting portion 34 has flexibility, it is possible to direct the engaging portion 35 to the right from the state shown in FIG. While maintaining this state, when the scaffold main body 10 is rotated 180 degrees clockwise around the axis and the long portion 33 is folded upward, as shown in FIG. A magnet 37a can be attached to the main surface 36f. That is, in the state of FIG. 5, the positions of the magnets 37a and 37b in the left-right direction are opposite to those in FIG. 1, and the magnet 37b, which was positioned on the right side in the state of FIG. is in a state where it can be visually recognized. As described above, the scaffold body 10 is half-rotated about the axis and the magnet 37a is fixed to the attached portion 36, so that the portion of the other end portion 13 to which the connecting portion 34 is attached (the upper end portion 13a in FIG. 2) is It is in a state in which it faces downward and the grip part 40 faces upward. In the state shown in FIG. 5, the connecting portion 34 is folded to be compact, so that the scaffolding device 1 can be easily transported and handled.

次に、足場装置1を送電線作業に使用する場合、作業者は、鉄塔に登って当該鉄塔の所定位置に達した後に、把持部40の開口40oに不図示のロープを引き掛けて、このロープによって足場装置1を作業者の位置(すなわち、上記所定位置)まで引き上げることができる。なお、ロープを使わずに足場装置1を作業者自身で所定の位置まで運搬してもよい。 Next, when using the scaffolding device 1 for power transmission line work, the worker climbs a steel tower and after reaching a predetermined position on the steel tower, hooks a rope (not shown) to the opening 40o of the grip part 40, and The scaffolding device 1 can be pulled up to the worker's position (that is, the predetermined position) by means of the rope. The scaffolding device 1 may be transported to a predetermined position by the worker himself without using the rope.

足場装置1を上記所定位置まで引き上げ、開口40oに通したロープを足場装置1から取り外した後、図5に示すように、作業者WMは、鉄塔における上記所定位置及びその近傍に自身を位置させて、連結部34(長尺部33)が折り畳まれた状態を維持したまま、足場本体10を主に鉛直方向及び左右方向に動かして、係合部35を送電線EWに係合させる。 After pulling up the scaffolding device 1 to the predetermined position and removing the rope passed through the opening 40o from the scaffolding device 1, as shown in FIG. Then, the scaffold body 10 is moved mainly in the vertical direction and the left-right direction while the connecting portion 34 (long portion 33) is kept folded, and the engaging portion 35 is engaged with the power transmission line EW.

このようにして係合部35を送電線EWに係合させる際、図5に示すように、作業者WMは、上側を向く把持部40のグリップ部42を把持することができる。そのため、足場本体10の本体部11を直接把持する場合に比べて、足場本体10を動かすことが容易である。 When engaging the engaging portion 35 with the power transmission line EW in this manner, the worker WM can grip the grip portion 42 of the grip portion 40 facing upward, as shown in FIG. Therefore, it is easier to move the scaffolding body 10 than when the body portion 11 of the scaffolding body 10 is directly gripped.

また、図5の状態では、付着部37が被付着部36に付着している。上記のように、付着部37は足場本体10の他端部13に取り付けられており、被付着部36は係合部35に取り付けられている。そのため、図5の状態では、足場本体10の他端部13が直接的に係合部35に固定されている。よって、足場本体10を動かしても連結部34(長尺部33)の遊動の影響を受けることがないため、足場本体10の動きの軌跡と係合部35の動きの軌跡とが概ね同一になる。したがって、係合部35を送電線EWに係合させることが容易であり、取り扱いが容易である。 Moreover, in the state of FIG. As described above, the attachment portion 37 is attached to the other end portion 13 of the scaffold body 10 , and the attached portion 36 is attached to the engagement portion 35 . Therefore, in the state of FIG. 5, the other end portion 13 of the scaffolding body 10 is directly fixed to the engaging portion 35 . Therefore, even if the scaffold body 10 is moved, it is not affected by the loose movement of the connecting part 34 (long part 33), so that the trajectory of the movement of the scaffold body 10 and the trajectory of the movement of the engaging part 35 are substantially the same. Become. Therefore, it is easy to engage the engaging portion 35 with the power transmission line EW, which facilitates handling.

ところで、フックを長尺物に引き掛ける際、フックが向く方向と長尺物の方向とのなす角度が垂直であれば、この角度が非垂直である場合に比べて、フックを長尺物に引き掛け易い。そのため、フックを長尺物に引き掛ける際には、フックが向く方向と長尺物の方向とをなるべく垂直に近づけることが好ましい。フックが向く方向が足場本体10の軸方向と非垂直の場合、フックが向く方向と上記長尺物に相当する送電線EWの方向とを垂直に近づけるためには、足場本体10を送電線EWに対して斜めに保持する必要があり、このように足場本体10を斜めに保持するためには、作業者は送電線EWから離れた位置に自身を位置させる必要がある。これに対し、本実施形態では、付着部37が被付着部36に付着している際にフックが向く方向Dfが足場本体10の軸方向に垂直であるため、足場本体10を送電線EWと平行に保持することによって、フックが向く方向Dfを送電線EWの方向に対して垂直にすることができる。つまり、本実施形態では、フックが向く方向Dfと送電線EWの方向とを垂直にするために、足場本体10を送電線EWに対して斜めに保持する必要がない。したがって、本実施形態では、作業者WMは、フックが向く方向Dfと送電線EWの方向とが垂直に近い状態でフックを送電線EWに係合させる作業を、送電線EWに近接した位置で行うことができる。よって、作業性がより向上し得る。 By the way, when hooking a long object with a hook, if the angle between the direction in which the hook faces and the direction of the long object is perpendicular, the hook is more likely to hang on the long object than when this angle is not perpendicular. Easy to pull. Therefore, when hooking the long object with the hook, it is preferable to make the direction in which the hook faces and the direction of the long object as close to perpendicular as possible. When the direction in which the hook faces is not perpendicular to the axial direction of the scaffold body 10, in order to make the direction in which the hook faces and the direction of the power transmission line EW corresponding to the long object perpendicular to each other, the scaffold body 10 must be aligned with the power line EW. In order to hold the scaffold body 10 obliquely in this way, the worker needs to position himself/herself away from the power transmission line EW. On the other hand, in the present embodiment, since the direction Df in which the hook faces when the attaching portion 37 is attached to the attached portion 36 is perpendicular to the axial direction of the scaffolding body 10, the scaffolding body 10 is connected to the power line EW. By keeping them parallel, the direction Df in which the hooks face can be made perpendicular to the direction of the transmission line EW. That is, in the present embodiment, it is not necessary to hold the scaffold body 10 obliquely with respect to the power transmission line EW so that the direction Df in which the hook faces and the direction of the power transmission line EW are perpendicular to each other. Therefore, in the present embodiment, the worker WM performs the work of engaging the hook with the power transmission line EW in a state where the direction Df in which the hook faces and the direction of the power transmission line EW are nearly perpendicular to each other at a position close to the power transmission line EW. It can be carried out. Therefore, workability can be further improved.

ただし、足場装置1によれば、仮に付着部37が被付着部36に付着している際にフックが向く方向Dfと足場本体10の軸方向とのなす角度が非垂直である場合であっても、足場本体10の他端部13が直接的に係合部35に固定された状態でフックを送電線EWに係合させることができる。すなわち、上記角度が仮に非垂直であっても、連結部34の遊動の影響を受けないことに変わりはないので、やはり係合部35を送電線EWに係合させることが容易であり、取り扱いが容易である。 However, according to the scaffolding device 1, even if the angle between the direction Df in which the hook faces when the attachment portion 37 is attached to the attached portion 36 and the axial direction of the scaffold body 10 is non-perpendicular. Also, the hook can be engaged with the power transmission line EW while the other end 13 of the scaffold body 10 is directly fixed to the engaging portion 35 . That is, even if the angle is non-perpendicular, there is no change in the influence of the loose movement of the connecting portion 34. Therefore, it is easy to engage the engaging portion 35 with the power transmission line EW. is easy.

係合部35を送電線EWに係合させて図5の状態にした後、作業者WMは、例えば以下のようにして、付着部37と被付着部36との付着状態を解除することができる。 After the engaging portion 35 is engaged with the power transmission line EW and the state of FIG. 5 is established, the operator WM can release the adhered state between the adhering portion 37 and the adhered portion 36, for example, as follows. can.

まず、作業者WMは、把持部40を把持して、足場本体10をフックが向く方向Dfとは反対方向に軸中心に概ね90度回転させる。上記のように、図5の状態におけるフックが向く方向Dfは右である。よって、本実施形態では、作業者WMは、足場本体10を軸中心に概ね90度左回転させる。図6は、足場本体10を軸中心に概ね90度左回転させた状態を示している。図6に示すように、足場本体10を軸中心に概ね90度左回転させることによって、把持部40が左側を向く。また、この左回転によって、マグネット37bが下側に位置し、マグネット37aが上側に位置する。足場本体10の中心軸Xを基準とする上側に着目すると、上側から下側に向かって、係合部35、被付着部36、マグネット37a、及び他端部13の順に並んでいる。 First, the worker WM grips the gripping portion 40 and rotates the scaffold body 10 approximately 90 degrees around the axis in the direction opposite to the direction Df in which the hook faces. As described above, the direction Df in which the hook faces in the state of FIG. 5 is right. Therefore, in the present embodiment, the worker WM rotates the scaffold body 10 counterclockwise approximately 90 degrees around the axis. FIG. 6 shows a state in which the scaffold main body 10 is rotated counterclockwise by approximately 90 degrees around the axis. As shown in FIG. 6, by rotating the scaffold body 10 to the left approximately 90 degrees around the axis, the gripping portion 40 faces leftward. Also, this counterclockwise rotation positions the magnet 37b downward and the magnet 37a upward. Focusing on the upper side of the scaffold body 10 with respect to the central axis X, the engaging portion 35, the attached portion 36, the magnet 37a, and the other end portion 13 are arranged in this order from the upper side to the lower side.

次に、作業者WMは、把持部40を把持して、図6の状態から足場本体10を軸中心に概ね90度左回転させつつ、足場本体10を下方に押圧する。この際、図6の状態では、係合部35が送電線EWに係合しているため、係合部35及び被付着部36の下方への移動が規制される。このため、下方に押す力がマグネット37aと足場本体10の他端部13とに効果的に作用する。その結果、図7に示すように、付着部37と被付着部36との付着状態、すなわち、係合部35と他端部13との固定状態が解除され、マグネット37a及び他端部13が被付着部36及び係合部35から離間するとともに、長尺部33の折り畳み状態が解かれる。こうして、長尺部33が元の長さとなる。また、足場本体10を図6の状態から概ね90度左回転させたため(すなわち、図5の状態から180度回転させたため)、図7の状態において、他端部13における連結部34が取り付けられる部位(上端部13a)の向き及び把持部40の向きが、それぞれ図1の状態に戻る。すなわち、他端部13における連結部34が取り付けられる部位(上端部13a)の向きが上側となり、把持部40の向きが下側となる。また、補助足場50が下側を向く。こうして、付着部37と被付着部36との付着状態が解除され、他方側取付部30の送電線EWへの取付が完了する。 Next, the worker WM grips the grip part 40 and pushes the scaffolding body 10 downward while rotating the scaffolding body 10 counterclockwise approximately 90 degrees from the state shown in FIG. At this time, since the engaging portion 35 is engaged with the power transmission line EW in the state of FIG. 6, downward movement of the engaging portion 35 and the adhered portion 36 is restricted. For this reason, the downward pressing force effectively acts on the magnet 37a and the other end portion 13 of the scaffold body 10 . As a result, as shown in FIG. 7, the attached state between the attached portion 37 and the attached portion 36, that is, the fixed state between the engaging portion 35 and the other end portion 13 is released, and the magnet 37a and the other end portion 13 are released. As the long portion 33 is separated from the adhered portion 36 and the engaging portion 35, the folded state of the long portion 33 is released. In this way, the long portion 33 becomes the original length. In addition, since the scaffold body 10 has been rotated counterclockwise approximately 90 degrees from the state shown in FIG. 6 (that is, rotated 180 degrees from the state shown in FIG. 5), in the state shown in FIG. The orientation of the portion (upper end portion 13a) and the orientation of the grip portion 40 return to the state shown in FIG. That is, the portion (upper end portion 13a) of the other end portion 13 to which the connecting portion 34 is attached faces upward, and the grip portion 40 faces downward. Also, the auxiliary scaffolding 50 faces downward. Thus, the attachment state between the attachment portion 37 and the attached portion 36 is released, and attachment of the other side attachment portion 30 to the power transmission line EW is completed.

なお、この実施形態の例では、マグネット37aを被付着部36に付着させることによってフックが向く方向Dを右にして、係合部35を足場本体10に固定する例を説明した。しかし、足場装置1では、付着部材であるマグネットが左右両側に取り付けられている。そのため、マグネット37bを被付着部36に付着させて、フックが向く方向Dfが左の状態で係合部35を足場本体10の他端部13に固定することもできる。フックが向く方向Dfが左の場合、係合部35を送電線EWに係合させた後に係合部35と足場本体10との固定状態を解除するためには、足場本体10を軸中心に概ね90度右回転させた後、さらに足場本体10を軸中心に概ね90度右回転させつつ足場本体10を下方に押せばよい。 In the example of this embodiment, the engaging portion 35 is fixed to the scaffold main body 10 by attaching the magnet 37a to the attached portion 36 so that the direction D in which the hook faces is set to the right. However, in the scaffolding device 1, magnets, which are attachment members, are attached to both left and right sides. Therefore, the magnet 37b can be attached to the attached portion 36, and the engaging portion 35 can be fixed to the other end portion 13 of the scaffold body 10 in a state in which the direction Df in which the hook faces is left. When the direction Df in which the hook faces is to the left, in order to release the fixed state between the engaging portion 35 and the scaffolding body 10 after engaging the engaging portion 35 with the power transmission line EW, the scaffolding body 10 must be rotated around the axis. After rotating the scaffolding body 10 to the right by approximately 90 degrees, the scaffolding body 10 may be pushed downward while rotating the scaffolding body 10 to the right by approximately 90 degrees about the axis.

なお、足場装置1は把持部40を備えているため、上記のように把持部40を把持すれば、足場本体10を軸中心に回転させることが容易である。 Since the scaffolding device 1 includes the gripping portion 40, the scaffolding main body 10 can be easily rotated around the axis by gripping the gripping portion 40 as described above.

本実施形態では、作業者WMは、足場装置1を図7の状態にした後、一方側取付部20を鉄塔に取り付ける。図8は、足場装置が送電線設備に懸架された状態を示す図であり、一方側取付部20が鉄塔STに取り付けられた状態を示している。なお、図8では、便宜上、作業者の図示が省略されている。 In this embodiment, the worker WM attaches the one-side attachment portion 20 to the steel tower after placing the scaffolding device 1 in the state shown in FIG. FIG. 8 is a diagram showing a state in which the scaffolding device is suspended from power transmission line equipment, and shows a state in which the one-side mounting portion 20 is mounted to the steel tower ST. In addition, in FIG. 8, the illustration of the worker is omitted for the sake of convenience.

図8に示すように、作業者は、鉄塔STにおける作業者の位置(又はその近傍)SPに一方側取付部20の長尺部24を巻き掛けた上、本実施形態では、一方側取付部20の係止部25を下側のリング状部材22に係合させる。その結果、一方側取付部20が鉄塔STに取り付けられる。なお、係止部25をリング状部材21に係合させてもよい。あるいは、一方側取付部20の長尺部24を位置SPに巻き掛けた上で、係止部25を接続部23や長尺部24に係合させてもよい。また、足場本体10の一端部12から導出された補助部60を上記位置SPの近傍に巻き掛け、補助部60の一方側の端部62に固定された係止部70を、補助部60における一端部12から外部に導出されている部分に係合させる。その結果、補助部60が鉄塔STに取り付けられる。こうして、一方側取付部20が鉄塔STに取り付けられ、かつ、他方側取付部30が送電線EWに取り付けられることによって、足場装置1が鉄塔STと送電線EWとの間に懸架され、図8の状態になる。 As shown in FIG. 8, the worker winds the long portion 24 of the one side mounting portion 20 around the worker's position (or its vicinity) SP on the steel tower ST, and in this embodiment, the one side mounting portion The locking portion 25 of 20 is engaged with the lower ring-shaped member 22 . As a result, the one-side attachment portion 20 is attached to the steel tower ST. Note that the locking portion 25 may be engaged with the ring-shaped member 21 . Alternatively, the locking portion 25 may be engaged with the connection portion 23 or the long portion 24 after the long portion 24 of the one-side attachment portion 20 is wound around the position SP. In addition, the auxiliary portion 60 led out from the one end portion 12 of the scaffold body 10 is wound around the position SP, and the locking portion 70 fixed to one end portion 62 of the auxiliary portion 60 is attached to the auxiliary portion 60. It is engaged with the portion led out from the one end portion 12 to the outside. As a result, the auxiliary part 60 is attached to the steel tower ST. In this way, the one-side mounting portion 20 is attached to the steel tower ST and the other-side mounting portion 30 is attached to the power transmission line EW, thereby suspending the scaffolding device 1 between the steel tower ST and the power transmission line EW. state.

上述のように、鉄塔STにおける一方側取付部20が取り付けられている部分(長尺部24が巻き掛けられている部分)である上記位置SPは、作業者の位置又はその近傍の位置であるため、この位置SPを送電線作業の作業起点SPと見なし得る。すなわち、図8の状態において、一方側取付部20は、送電線設備の作業起点SP側である鉄塔STに取り付けられている。また、足場本体10の一端部12は、足場本体10における作業起点SP側に向けられた端部であり、作業起点SP近傍に位置している。図8の状態とした後、作業起点SPにいる(あるいは、いるとみなし得る)作業者は、作業起点SPを起点として、一端部12近傍における本体部11の上面に足を載せた後、他端部13側に向かって本体部11上を移動することができる。このように、足場本体10は、送電線作業における主な足場として機能する。作業者は、足場本体10を足場とし、かつ、送電線EWに設けられた碍子等(図示せず)を把持することで、送電線作業を行う位置まで容易に移動することができる。 As described above, the position SP, which is the portion of the steel tower ST to which the one-side mounting portion 20 is attached (the portion around which the long portion 24 is wound), is the worker's position or a position in the vicinity thereof. Therefore, this position SP can be regarded as the work starting point SP of the power line work. That is, in the state of FIG. 8, the one-side attachment portion 20 is attached to the steel tower ST on the work starting point SP side of the transmission line equipment. One end portion 12 of the scaffold body 10 is an end portion of the scaffold body 10 directed toward the work start point SP, and is located near the work start point SP. After the state of FIG. 8 is established, the worker who is (or can be considered to be) at the work start point SP uses the work start point SP as a starting point, puts his foot on the upper surface of the main body 11 in the vicinity of the one end 12, and It can move on the body portion 11 toward the end portion 13 side. In this way, the scaffold body 10 functions as a main scaffold in power line work. By using the scaffold body 10 as a foothold and holding an insulator or the like (not shown) provided on the power transmission line EW, the worker can easily move to a position for performing power transmission line work.

また、図8の状態では、把持部40が下側を向いているため、作業者が本体部11上を移動する際に把持部40が移動の妨げになることが抑制される。 Further, in the state of FIG. 8 , since the gripping portion 40 faces downward, it is suppressed that the gripping portion 40 interferes with the movement of the operator when moving on the main body portion 11 .

また、図8の状態では、下側を向く補助足場50が他方側取付部30に近い側に設けられている。そのため、作業者は、送電線作業を行う位置まで達した後、例えば、本体部11に腰を掛けつつ、補助足場50の開口52oに足を入れることができる。こうすることで、作業者は、送電線作業を行う位置で姿勢を安定させることができ、送電線作業の作業効率が向上し得る。 In addition, in the state of FIG. 8, the auxiliary scaffolding 50 facing downward is provided on the side closer to the other side mounting portion 30 . Therefore, after reaching the position where the power transmission line work is to be performed, the worker can put his or her feet into the opening 52o of the auxiliary scaffolding 50 while sitting on the main body 11, for example. By doing so, the worker can stabilize the posture at the position where the power transmission line work is to be performed, and the work efficiency of the power transmission line work can be improved.

また、本発明の足場装置1は、足場本体10の内部を貫通する補助部60を備えている。この補助部60の他方側の端部63は、係合部35に固定されている。そのため、補助部60を上述のように鉄塔STに巻き掛けて鉄塔STに固定することによって、足場本体10に加えて補助部60が鉄塔STと送電線EWとの間に懸架された状態となる。したがって、仮に足場本体10が割れて分裂した場合でも、補助部60によって足場装置1自体の分裂が回避される。 Further, the scaffolding device 1 of the present invention includes an auxiliary part 60 penetrating through the inside of the scaffolding main body 10 . An end portion 63 on the other side of the auxiliary portion 60 is fixed to the engaging portion 35 . Therefore, by winding the auxiliary part 60 around the steel tower ST and fixing it to the steel tower ST as described above, the auxiliary part 60 in addition to the scaffold body 10 is suspended between the steel tower ST and the transmission line EW. . Therefore, even if the scaffolding main body 10 cracks and splits, the auxiliary part 60 prevents the splitting of the scaffolding device 1 itself.

また、足場装置1は、上記のような効果に加えて、例えば以下の効果を奏する。 In addition to the effects described above, the scaffolding device 1 has, for example, the following effects.

足場装置1では、主な足場となる足場本体10が1つの筒状の部材から構成されるため、足場が例えば梯子状に構成された足場装置に比べて、足場の構造が単純であり、また、足場が小型化し得る。そのため、仮に梯子状の足場と同じ材料で足場本体を構成したとしても、梯子状の足場の足場装置に比べて、軽量化することが可能である。特に、本実施形態の足場装置1では、上記のように、足場本体10がFRPで形成されている。FRPは軽量で強度の高い材料であるため、足場装置の総重量を7.0kg程度まで軽量化することが可能である。このように、本実施形態の足場装置1によれば、軽量化することが容易であり、軽量化によって取扱性が向上する。 In the scaffolding device 1, the scaffolding main body 10, which is the main scaffolding, is composed of a single cylindrical member. , the scaffold can be miniaturized. Therefore, even if the scaffolding body is made of the same material as the ladder-shaped scaffolding, the scaffolding device can be made lighter than the ladder-shaped scaffolding. In particular, in the scaffolding device 1 of this embodiment, the scaffolding main body 10 is made of FRP as described above. Since FRP is a lightweight and high-strength material, it is possible to reduce the total weight of the scaffolding device to about 7.0 kg. Thus, according to the scaffolding device 1 of the present embodiment, it is easy to reduce the weight, and the weight reduction improves the handleability.

ところで、他方側取付部30(長尺部33)は図8に示すように巻き掛けられずに送電線EWに取り付けられる。このため、図8のように足場装置1が送電線EWと鉄塔STとの間に懸架された状態における他方側取付部30の鉛直方向の長さは、本来の長さと概ね等しい。一方、一方側取付部20(長尺部24)は、図8に示すように巻き掛けられて鉄塔STに取り付けられる。このため、図8のように足場装置1が懸架された状態における一方側取付部20の鉛直方向の長さは、本来の長さよりも短くなり、例えば、本来の長さの概ね1/2になる。このため、他方側取付部30の長さが一方側取付部20の長さと同じか又は長い場合、足場装置1が送電線EWと鉄塔STとの間に懸架された状態において、足場本体10が他端部13から一端部12に向かって上方に傾く。しかし、本実施形態では、上記のように、他方側取付部30の長尺部33が一方側取付部20の長尺部24よりも短いため、他方側取付部30が一方側取付部20よりも短くなっている。したがって、足場装置1が送電線EWと鉄塔STとの間に懸架された状態において、足場本体10が上記のように他端部13から一端部12に向かって上方に傾くことが抑制される。なお、他方側取付部30の長さは、一方側取付部20の長さの例えば1/2であってもよい。 By the way, the other side attachment portion 30 (long portion 33) is attached to the power transmission line EW without being wound as shown in FIG. Therefore, the vertical length of the other side mounting portion 30 in the state in which the scaffolding device 1 is suspended between the transmission line EW and the steel tower ST as shown in FIG. 8 is substantially equal to the original length. On the other hand, the one-side attachment portion 20 (long portion 24) is wound around and attached to the steel tower ST as shown in FIG. Therefore, the vertical length of the one-side mounting portion 20 in the state in which the scaffolding device 1 is suspended as shown in FIG. Become. Therefore, when the length of the other side mounting portion 30 is the same as or longer than the length of the one side mounting portion 20, the scaffolding body 10 is not It tilts upward from the other end 13 toward the one end 12 . However, in this embodiment, as described above, the long portion 33 of the other side mounting portion 30 is shorter than the long portion 24 of the one side mounting portion 20 , so the other side mounting portion 30 is shorter than the one side mounting portion 20 . is also shorter. Therefore, when the scaffolding device 1 is suspended between the transmission line EW and the steel tower ST, the scaffolding body 10 is prevented from tilting upward from the other end portion 13 toward the one end portion 12 as described above. The length of the other side mounting portion 30 may be, for example, half the length of the one side mounting portion 20 .

以上説明したように、本実施形態に係る足場装置1は、1つの筒状の足場本体10と、足場本体10のうち作業起点SP側に向けられる一端部12に設けられており、架空設備のうち作業起点SP側(鉄塔ST)に取り付けられる一方側取付部20と、足場本体10のうち一端部12側とは反対側の他端部13に設けられる他方側取付部30と、を備えており、他方側取付部30は、架空設備のうち作業起点SP側とは反対側(送電線EW)に係合する係合部35と、足場本体10の他端部13に取り付けられており、当該他端部13と係合部35とを連結する可撓性を有する連結部34と、係合部35に設けられる被付着部36と、足場本体10の他端部13に設けられており、連結部34を折り畳むことによって被付着部36に付着する付着部37と、を含む。本実施形態によれば、このような構成により、取り扱いが容易な足場装置が実現されている。 As described above, the scaffolding device 1 according to the present embodiment is provided with one cylindrical scaffolding main body 10 and one end portion 12 of the scaffolding main body 10 directed toward the work starting point SP side. Among them, the one side mounting portion 20 mounted on the work starting point SP side (steel tower ST) and the other side mounting portion 30 provided on the other end portion 13 of the scaffold body 10 opposite to the one end portion 12 side are provided. The other side mounting portion 30 is mounted to an engaging portion 35 that engages on the opposite side (power transmission line EW) of the overhead equipment from the work start point SP side and the other end portion 13 of the scaffold body 10, A connecting portion 34 having flexibility that connects the other end portion 13 and the engaging portion 35 , an adhered portion 36 provided in the engaging portion 35 , and the other end portion 13 of the scaffold body 10 . , and an attachment portion 37 that attaches to the attached portion 36 by folding the connecting portion 34 . According to this embodiment, such a configuration realizes a scaffolding device that is easy to handle.

以上、本発明について上記実施形態を例に説明したが、本発明はこれに限定されるものではない。 As described above, the present invention has been described by taking the above embodiment as an example, but the present invention is not limited to this.

例えば、上記実施形態では、付着部37が被付着部36に付着している際に係合部35が向く側及びその反対側の他端部13の部位にそれぞれ設けられる一対の付着部材(マグネット37a,37b)から付着部37がなる例を説明したが、これに限定されるものではない。例えば、一対の付着部材が対向する方向が左右方向に対して斜めであってもよい。あるいは、他端部13の外周面のうち中心軸Xに対して線対称の位置に、付着部材としてマグネットを取り付けてもよい。また、他端部13の外周面のうち軸方向における所定の位置に、1つのリング状のマグネットを付着部材として取り付けてもよい。 For example, in the above-described embodiment, a pair of attachment members (magnet 37a and 37b) have been described as an example, but the present invention is not limited to this. For example, the direction in which the pair of attachment members face each other may be oblique with respect to the left-right direction. Alternatively, a magnet may be attached as an attachment member at a line-symmetrical position with respect to the central axis X on the outer peripheral surface of the other end portion 13 . Further, one ring-shaped magnet may be attached as an attachment member to a predetermined position in the axial direction on the outer peripheral surface of the other end portion 13 .

また、上記実施形態では、付着部37がマグネットから形成され、被付着部36が磁性材料から形成される例を説明した。しかし、付着部37が磁性材料から形成され、被付着部36がマグネットから形成されてもよい。 Further, in the above-described embodiment, an example has been described in which the adhering portion 37 is made of a magnet and the attached portion 36 is made of a magnetic material. However, the attaching portion 37 may be made of a magnetic material, and the attached portion 36 may be made of a magnet.

また、上記実施形態では、付着部と被付着部とが磁気的に付着して互いに固定される例を説明したが、これに限定されるものではない。例えば、付着部と被付着部とは、一方が他方に構造的に結合(例えば、嵌合)して互いに付着する構成であってもよい。すなわち、本明細書における「付着」の概念には、一方が他方に磁気的に付着する関係のみならず、一方が他方に構造的に結合するような関係も含まれる。 Further, in the above-described embodiment, an example in which the attaching portion and the attached portion are magnetically attached and fixed to each other has been described, but the present invention is not limited to this. For example, the attachment portion and the attachment portion may be configured such that one is structurally coupled (eg, fitted) to the other and attached to each other. That is, the concept of "attachment" in this specification includes not only a relationship in which one is magnetically attached to the other, but also a relationship in which one is structurally bonded to the other.

また、上記実施形態では、把持部40が他端部13における連結部34が取り付けられる部位とは反対側を向いている例を説明したが、この構成は必須ではない。ただし、作業者が足場本体10上を移動する際に把持部40が移動の妨げなることを抑制する観点から、把持部40は、他端部13における連結部34が取り付けられる部位と同じ側以外を向いていることが好ましい。また、把持部40を設けることは必須ではない。 Also, in the above-described embodiment, an example was described in which the grip portion 40 faces the opposite side of the portion of the other end portion 13 to which the connecting portion 34 is attached, but this configuration is not essential. However, from the viewpoint of preventing the gripping portion 40 from interfering with the movement of the worker when moving on the scaffolding body 10, the gripping portion 40 is attached to a portion other than the same side of the other end portion 13 as the portion to which the connecting portion 34 is attached. preferably facing Moreover, providing the grip portion 40 is not essential.

また、上記実施形態では、足場装置が補助足場50を備える例を説明したが、補助足場50を設けることは必須ではない。 Also, in the above-described embodiment, an example in which the scaffolding device includes the auxiliary scaffolding 50 has been described, but provision of the auxiliary scaffolding 50 is not essential.

また、上記実施形態では、足場装置が補助部60を備える例を説明したが、補助部60を設けることは必須ではない。 Further, in the above-described embodiment, an example in which the scaffolding device includes the auxiliary section 60 has been described, but provision of the auxiliary section 60 is not essential.

また、上記実施形態では、説明の都合上、他方側取付部30を送電線EWに取り付けた後に一方側取付部20を鉄塔STに取り付ける例を説明した。しかし、一方側取付部20を鉄塔STに取り付けた後に他方側取付部30を送電線EWに取り付けてもよい。 Further, in the above-described embodiment, for convenience of explanation, the example in which the one-side mounting portion 20 is mounted to the steel tower ST after the other-side mounting portion 30 is mounted to the power transmission line EW has been described. However, the other side attachment portion 30 may be attached to the transmission line EW after the one side attachment portion 20 is attached to the steel tower ST.

また、上記実施形態では、足場装置が送電線作業に使用される例を説明した。しかし、本発明の足場装置は、他の架空設備に対する作業においても使用し得るものである。 Further, in the above embodiment, an example in which the scaffolding device is used for power transmission line work has been described. However, the scaffolding system of the present invention can also be used in operations on other overhead installations.
