従来、キュービクル、配電盤、制御盤、分電盤、路上開閉器等の活線や充電部に隣接した箇所で作業者が当該箇所に手を入れて機器等の修理、保守、点検等の作業を行う場合、作業前に絶縁シートや絶縁カバーなどで、充電部等を被い、安全性を確保してから作業を行っていた。 Conventionally, a worker puts his hand in a place adjacent to a live line or a charging part of a cubicle, a power distribution board, a control board, a distribution board, a road switch, etc., and repairs, maintains, inspects the equipment, etc. When doing this, the work was done after the charging part was covered with an insulating sheet or an insulating cover to ensure safety before the work.
これらの絶縁シートや絶縁カバーは、例えば特許文献１〜４に示すように、充電部の形状に合わせて種々の形状に成形されていたり、可撓性のあるシート状のものから構成されており、これらの物を充電部に被せているものが多い。 As shown in Patent Documents 1 to 4, these insulating sheets and insulating covers are formed into various shapes according to the shape of the charging portion, or are made of a flexible sheet. , Many of these items are covered on the charging part.
しかしながら、作業者は、まず、これらの絶縁シートや絶縁カバーを前記充電部に被せなければならず、この充電部に絶縁シートや絶縁カバーを掛ける作業自体、作業者が充電部に接触して感電する危険がある。 However, the operator must first cover the charging portion with these insulating sheets or insulating covers, and the work itself of hanging the insulating sheet or insulating cover on the charging portion causes the operator to come into contact with the charging portion and receive an electric shock. There is a danger of doing.
そこで、この発明は上述の課題を解決するため、上記のような充電部に近接した箇所で作業を行う場合に、充電部を被うという発想でなく、充電部に近接した箇所に、絶縁された作業空間を安全で簡易に形成し、確保する治具及びこの冶具を用いた当該作業空間の形成又は確保方法を提供することを目的としたものである。 Therefore, in order to solve the above-mentioned problems, the present invention does not have the idea of covering the charging part when performing work in a place close to the charging part as described above, but is insulated in a place close to the charging part. It is an object of the present invention to provide a jig for safely and easily forming and securing a working space, and a method for forming or securing the working space using the jig.
請求項１の発明は、充電部に隣接した箇所に絶縁された作業空間を形成する絶縁シートであって、一方向には剛性を有し、当該一方向に対して直角な方向に対しては可撓性及び弾性を有する絶縁シート部材から成り、前記作業空間の形状に合わせて前記可撓性及び弾性がある方向に折り曲げ又は湾曲させて当該絶縁シート状部材を立体化させ、当該絶縁シート部材を前記作業スペースの前方から後方へ、剛性のある方向に前記シート状部材を合わせて挿入し、前記作業空間に隣接した充電部との間に絶縁シート部材を介在させる構造である絶縁された作業空間形成又は確保治具とした。 The invention of claim 1 is an insulating sheet that forms an insulated work space at a location adjacent to a charging unit, has rigidity in one direction, and is perpendicular to the one direction. The insulating sheet member is made of a flexible and elastic insulating sheet member, and is bent or curved in a direction having the flexibility and elasticity according to the shape of the work space to make the insulating sheet-like member three-dimensional. Is inserted from the front to the rear of the work space in a rigid direction, and the insulating sheet member is interposed between the charging portion adjacent to the work space. It was used as a space forming or securing jig.
請求項２の発明は、前記絶縁シート状治具は、断面がＵ字型、Ｌ字型、Ｏ型、四角形型のいずれかに立体化させて成る、請求項１に記載の絶縁された作業空間形成又は確保治具とした。 The invention of claim 2 is the insulated work according to claim 1, wherein the insulating sheet-shaped jig has a three-dimensional cross section of U-shaped, L-shaped, O-shaped, or quadrangular. It was used as a space forming or securing jig.
また、請求項３の発明は、充電部に隣接した箇所に絶縁された作業空間を形成又は確保する方法において、一方向には剛性を有し、当該一方向に対して直角な方向に対しては可撓性及び弾性がある絶縁シート部材を前記作業空間の形状に合わせて折り曲げ又は湾曲させて立体化し、当該絶縁シート状部材を、剛性のある方向に合わせて前記作業空間の前方から後方に挿入し、隣接する充電部との間に当該絶縁シート状部材を介在させる、絶縁された作業空間形成又は確保方法とした。 Further, the invention of claim 3 is a method of forming or securing an insulated work space at a portion adjacent to a charging portion, which has rigidity in one direction and is perpendicular to the one direction. Bends or bends a flexible and elastic insulating sheet member according to the shape of the work space to make it three-dimensional, and aligns the insulating sheet-like member in a rigid direction from the front to the rear of the work space. It is a method of forming or securing an insulated work space by inserting and interposing the insulating sheet-like member between the adjacent charging part.
また、請求項４の発明は、前記絶縁シート状部材を複数枚使用して立体化し、各絶縁シート状部材相互の接続箇所を絶縁テープで接着する、前記請求項３に記載の絶縁された作業空間を形成又は確保する方法とした。 The insulated operation according to claim 3, wherein a plurality of the insulating sheet-shaped members are used to form a three-dimensional structure, and the connection points between the insulating sheet-shaped members are bonded with insulating tape. It was a method of forming or securing a space.
請求項１〜４の各発明によれば、作業空間の前方からスライドさせて絶縁シート状部材から成る治具を作業空間に挿入できるため、作業空間脇の充電部に作業者の手を近づけることなく、治具を作業空間に設置でき、安全である。 According to each of the inventions of claims 1 to 4, since the jig made of the insulating sheet-like member can be inserted into the work space by sliding from the front of the work space, the operator's hand should be brought close to the charging portion on the side of the work space. It is safe because the jig can be installed in the work space.
しかも、絶縁シート状部材は、折り曲げたり、丸めたりしても、その形状が元に戻る素材から成るので、作業空間の側面に突っ張り、作業空間が簡易にしっかり確保、維持できる。従って、充電部が隣接していても、絶縁された作業空間となるため、当該作業空間内で安全に作業をすることが出来る。 Moreover, since the insulating sheet-like member is made of a material whose shape returns to its original shape even when it is bent or rolled, it can be stretched to the side surface of the work space to easily and firmly secure and maintain the work space. Therefore, even if the charging units are adjacent to each other, the work space is insulated, so that the work can be safely performed in the work space.
また、当該作業空間形成又は確保治具は、絶縁シート状部材を折り曲げたり湾曲させたりして形成するため、作業が終われば、容易に撤去でき、極めて便利である。しかも、上述の様に復元性があるため、他の作業空間の確保において当該絶縁シート状部材から成る治具を何度でも使用できる。 Further, since the work space forming or securing jig is formed by bending or bending the insulating sheet-like member, it can be easily removed after the work is completed, which is extremely convenient. Moreover, since it has resilience as described above, the jig made of the insulating sheet-like member can be used many times in order to secure another work space.
特に、請求項４の発明では、複数枚の絶縁シート状部材を立体化させるのに、絶縁テープを用いて各絶縁シート部材相互を接着させて接続するため、組み立てられた治具が強固になり、作業中無闇に崩れたりしない。 In particular, in the invention of claim 4, in order to make a plurality of insulating sheet-like members three-dimensional, each insulating sheet member is bonded and connected to each other by using insulating tape, so that the assembled jig becomes strong. , Does not collapse indiscriminately during work.
（実施の形態例１）
この発明の実施の形態例１の絶縁された作業空間の形成又は確保治具及び方法を図１〜図６に基づいて説明する。
(Example 1 of the embodiment)
The jig and method for forming or securing an insulated work space according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 6.
まず、この発明の絶縁された作業空間の形成又は確保治具を用いる、充電部が近接した作業箇所の例を説明する。図７に示すように箱型の配電盤Ａがある。図７は配電盤の扉を取り外した正面図であり、多数の充電部Ｂ１が存在し、これらの充電部Ｂ１に隣接した箇所や、当該充電部Ｂ１の奥部の箇所を補修したり点検したりする作業の必要がある。 First, an example of a work place where a charging unit is close to each other using the jig for forming or securing an insulated work space of the present invention will be described. As shown in FIG. 7, there is a box-shaped switchboard A. FIG. 7 is a front view in which the door of the switchboard is removed, and there are a large number of charging parts B1, and repairs and inspections are performed on the parts adjacent to these charging parts B1 and the parts at the back of the charging part B1. Need to work.
この様な補修や点検に際して、絶縁された作業空間を簡易に形成し、確保する必要がある。そこでこれらの作業空間を形成又は確保する治具を開発した。 For such repairs and inspections, it is necessary to easily form and secure an insulated work space. Therefore, we have developed a jig that forms or secures these work spaces.
当該治具として、一方向には剛性を有し、当該一方向に対して直角な方向に対しては可撓性及び弾性を有する絶縁シート部材１を用意する。当該絶縁シート部材１はとしては、具体的には、プラスチックダンボール等が挙げられる。 As the jig, an insulating sheet member 1 having rigidity in one direction and flexibility and elasticity in a direction perpendicular to the one direction is prepared. Specific examples of the insulating sheet member 1 include plastic cardboard and the like.
この絶縁シート状部材１は四辺形のものを２枚用意し、図２に示すように、夫々を断面Ｌ字型に折り曲げ、相互に反対向きにして絶縁四辺形筒２を形成させる。この場合、絶縁シート状部材１の可撓性及び弾性を有する側で折り曲げる。 Two quadrilateral members 1 are prepared, and as shown in FIG. 2, each of the insulating sheet-shaped members 1 is bent into an L-shaped cross section, and the insulating quadrilateral cylinders 2 are formed in opposite directions. In this case, the insulating sheet-like member 1 is bent on the flexible and elastic side.
そして、図１に示すように、これらのＬ字型に折り曲げた各絶縁シート１を、配電盤Ｂの充電部Ｂ１に近接した箇所に、手前から奥部に差し込む。この場合、絶縁シート状部材１の剛性を有する側を前後にして差し込む。これにより前記絶縁四辺形筒２により四方を絶縁シート１で囲まれた作業空間３が形成される。 Then, as shown in FIG. 1, each of these L-shaped bent insulating sheets 1 is inserted from the front to the back at a position close to the charging portion B1 of the switchboard B. In this case, the insulating sheet-like member 1 is inserted with the rigid side facing back and forth. As a result, the insulating quadrilateral cylinder 2 forms a working space 3 surrounded on all sides by the insulating sheet 1.
この際、２枚の絶縁シート状部材１、１の各端部に絶縁テープ（図示省略）を貼ってこれらの２枚の絶縁シート状部材１を接続すると、作業空間３が無闇に崩れたりしない。 At this time, if an insulating tape (not shown) is attached to each end of the two insulating sheet-shaped members 1 and 1 to connect these two insulating sheet-shaped members 1, the work space 3 does not collapse unnecessarily. ..
従って、作業者は、図３に示すように、当該作業空間３に手を入れて奥部の接続部材４の作業等をすることが出来、その際、当該作業空間３に隣接して充電部Ｂ１があっても、絶縁シート状部材１が介在しているので、当該作業空間３の中で安全に作業を行うことが出来る。 Therefore, as shown in FIG. 3, the operator can put his / her hand in the work space 3 to work on the connecting member 4 at the back, and at that time, the charging unit is adjacent to the work space 3. Even if there is B1, since the insulating sheet-like member 1 is interposed, the work can be safely performed in the work space 3.
図４は、絶縁シート状部材１１を断面Ｌ字型に折り曲げたもので、当該Ｌ字型の絶縁シート状部材１１を用いて作業空間３を形成する場合もある。 FIG. 4 shows an insulating sheet-shaped member 11 bent into an L-shaped cross section, and the working space 3 may be formed by using the L-shaped insulating sheet-shaped member 11.
また、図５に示すように、絶縁シート状部材１２を折り曲げて逆向きのチャネル溝型の作業空間３を形成することもできる。さらに、図６に示すように、絶縁シート状部材１３を断面Ｕ字型に湾曲させて作業空間３を形成することもできる。 Further, as shown in FIG. 5, the insulating sheet-like member 12 can be bent to form a channel groove type working space 3 in the opposite direction. Further, as shown in FIG. 6, the insulating sheet-like member 13 can be curved in a U-shaped cross section to form the work space 3.
なお、上記実施の形態例では、充電部に近接した箇所での作業箇所として配電盤Ｂを示したが、配電盤に限らず、キュービクル、制御盤、分電盤、路上開閉器等の活線や充電部に隣接した箇所に広く適用できる。 In the above embodiment, the switchboard B is shown as a work place near the charging unit, but it is not limited to the switchboard, but the live line and charging of cubicles, control boards, distribution boards, road switches, etc. It can be widely applied to the part adjacent to the part.
