なお、図2(b)に示されるように、吊部33の円の中心Pが開閉器1本体の重心Gの鉛直上方に位置している。これにより、開閉器1を水平に保持でき安定して吊下げることができるため最良である。しかしながら、吊部33の円の中心Pを開閉器1本体の重心Gから多少偏移させて開閉器1を任意の方向に傾斜させてもよい。また、両軸受孔20bに挿通された軸部31は、両側壁20aの外側にピン等を設けて抜け防止されている。
As shown in FIG. 1, the hanging portion 33 is located at the center P of the circle of the hanging portion 33 vertically above the center of gravity G of the switch body 1 when viewed from the operation handle 10 (front surface 1 a).
In addition, as FIG.2 (b) shows, the center P of the circle | round | yen of the hanging part 33 is located in the perpendicular | vertical upper direction of the gravity center G of the switch 1 main body. This is best because the switch 1 can be held horizontally and can be stably suspended. However, the switch 1 may be inclined in an arbitrary direction by slightly shifting the center P of the circle of the hanging portion 33 from the center of gravity G of the switch 1 main body. Further, the shaft portion 31 inserted through the both bearing holes 20b is prevented from being removed by providing pins or the like on the outside of the side walls 20a.

次に、前述のように構成された開閉器1の取付装置3の操作態様について説明する。
図2(b)に二点鎖線で示されるように、開閉器1の輸送時には、取付装置3は、両側の吊下げボルト22及び吊部材32が本体取付部材20の上面に対して平行となるように軸部31を回動中心として回動し、収納された状態とされる。この際、吊下げボルト22に取り付けられている支え部材23は、本体取付部材20の規制片20eに当接し、前側腕金保持部材20cよりも外側に位置している。そして、支え部材23は、両側のナット24が手で締め付けられることで、スペーサ25により前側腕金保持部材20cの外側面に押し付けられ固定されている。また、吊部材32は、支え部材23の上方に位置して、両側のナット24が手で締め付けられることにより、軸部31が両吊下げボルト22により両軸受孔20bの内面に押し付けられ固定されている。
Next, an operation mode of the mounting device 3 for the switch 1 configured as described above will be described.
As shown by a two-dot chain line in FIG. 2B, when the switch 1 is transported, the attachment device 3 has the suspension bolts 22 and the suspension members 32 on both sides parallel to the upper surface of the body attachment member 20. As described above, the shaft 31 is rotated about the rotation center, and is stored. At this time, the support member 23 attached to the suspension bolt 22 is in contact with the restriction piece 20e of the main body attachment member 20 and is located on the outer side of the front arm metal holding member 20c. The support member 23 is pressed and fixed to the outer surface of the front armrest holding member 20c by the spacer 25 by manually tightening the nuts 24 on both sides. The suspension member 32 is positioned above the support member 23, and the nuts 24 on both sides are tightened by hand, whereby the shaft portion 31 is pressed against the inner surfaces of both bearing holes 20b by both suspension bolts 22. ing.

開閉器1を電柱上の腕金15に取り付ける際には、両側のナット24を緩め、吊部材32と両吊下げボルト22とが軸部31に対して回動可能な状態とする。また、固定金具29を支え部材23から外すとともに、右側の吊下げボルト22から支え部材23の溝23bを外し、支え部材23を左側の吊下げボルト22に対して回動可能な状態とする。その後、吊部材32を開閉器1の背面1c側へ回動させ、吊部材32を立設させる。そして、クレーン等のフックを吊部材32の吊部33に引っ掛け電柱上の腕金15まで持ち上げる。この際、図1に示されるように、開閉器1本体の重心Gの上方に吊部33の中心Pが位置するため、開閉器1が開閉器1の正面1aに対して垂直方向となるブッシング11,12がそれぞれ突設された両側面1d,1eの方向すなわち左右方向に傾くことはなく水平の状態となる。   When the switch 1 is attached to the arm metal 15 on the utility pole, the nuts 24 on both sides are loosened so that the suspension member 32 and both suspension bolts 22 are rotatable with respect to the shaft portion 31. In addition, the fixing bracket 29 is removed from the support member 23, and the groove 23 b of the support member 23 is removed from the right suspension bolt 22 so that the support member 23 can rotate with respect to the left suspension bolt 22. Then, the suspension member 32 is rotated to the back surface 1c side of the switch 1, and the suspension member 32 is erected. And hooks, such as a crane, are hooked on the suspension part 33 of the suspension member 32, and it lifts to the brace 15 on a utility pole. At this time, as shown in FIG. 1, since the center P of the hanging portion 33 is located above the center of gravity G of the main body of the switch 1, the bushing in which the switch 1 is perpendicular to the front surface 1a of the switch 1 is provided. 11 and 12 do not incline in the direction of the both side surfaces 1d and 1e from which the respective projections 12 and 12 are projected, that is, in the left-right direction.

図2(a)に示されるように、電柱上の腕金15を本体取付部材20の凹部20d,20gに当接させる。そして、右側の吊下げボルト22を開閉器1の背面1c側へ回動させ、右側の吊下げボルト22を吊部材32の水平部34bに当接させ仮置きする。また、左側の吊下げボルト22を開閉器1の背面1c側へ回動させた後、支え部材23を回動させ、支え部材23の溝23b内に右側の吊下げボルト22を挿入し、固定金具29を支え部材23に係合させる。これにより、本体取付部材20の凹部20d,20gと支え部材23との間に腕金15を挟み、ナット24をラチェット工具により締め付けることにより開閉器1が電柱上の腕金15に取り付けられる。この際、スペーサ25が両吊下げボルト22の支え部材23とナット24との間に環装されているため、ラチェット工具の回動範囲に吊部材32の接続部34等がない。よって、ラチェット工具により締め付ける際に、吊部材32に接触することがないので、作業性がよい。その後、クレーン等のフックを吊部材32の吊部33から外し、吊部材32の吊部33を開閉器1の背面1c方へ回動し、腕金15に当接して倒しておく。   As shown in FIG. 2A, the arm metal 15 on the utility pole is brought into contact with the recesses 20 d and 20 g of the main body attachment member 20. Then, the right suspension bolt 22 is rotated to the back surface 1 c side of the switch 1, and the right suspension bolt 22 is temporarily placed in contact with the horizontal portion 34 b of the suspension member 32. Further, after the left suspension bolt 22 is rotated to the back surface 1c side of the switch 1, the support member 23 is rotated, and the right suspension bolt 22 is inserted into the groove 23b of the support member 23 and fixed. The metal fitting 29 is engaged with the support member 23. As a result, the armature 15 is sandwiched between the recesses 20d and 20g of the main body attachment member 20 and the support member 23, and the nut 1 is tightened with the ratchet tool, whereby the switch 1 is attached to the armature 15 on the utility pole. At this time, since the spacer 25 is provided between the support member 23 of the suspension bolts 22 and the nut 24, there is no connection portion 34 of the suspension member 32 in the rotation range of the ratchet tool. Therefore, when tightening with a ratchet tool, workability is good because the suspension member 32 is not contacted. Thereafter, the hook of a crane or the like is removed from the suspension portion 33 of the suspension member 32, the suspension portion 33 of the suspension member 32 is rotated toward the back surface 1 c of the switch 1, and is brought into contact with the arm metal 15 and brought down.

開閉器1を電柱上の腕金15から取り外す際には、ナット24をラチェット工具により緩め、吊部材32を立設させる。そして、吊部材32の吊部33にクレーン等のフックを引っ掛け、開閉器1を持ち上げ、ナット24を完全に緩め、支え部材23の溝23bと右側の吊下げボルト22との係合を解除し、開閉器1を腕金15から取り外す。そして、開閉器1が地面に下ろされると、図2(b)に二点鎖線で示されるように、吊下げボルト22及び吊部材32は開閉器1の正面1a側へ回動され、本体取付部材20の規制片20eに支え部材23が当接した状態で、本体取付部材20に収納される。吊部材32は、支え部材23の上方に当接させて、両側のナット24を手で締め付けると、支え部材23が前側腕金保持部材20cに接触し、吊部材32とともに固定される。また、吊部材32の軸部31が両軸受孔20bの内面に当接固定される。   When removing the switch 1 from the arm bracket 15 on the utility pole, the nut 24 is loosened with a ratchet tool, and the suspension member 32 is erected. And hooks, such as a crane, are hooked on the suspension part 33 of the suspension member 32, the switch 1 is lifted, the nut 24 is completely loosened, and the engagement between the groove 23b of the support member 23 and the right suspension bolt 22 is released. The switch 1 is removed from the arm bracket 15. When the switch 1 is lowered to the ground, as shown by a two-dot chain line in FIG. 2B, the suspension bolt 22 and the suspension member 32 are rotated to the front 1a side of the switch 1 to attach the body. The support member 23 is in contact with the regulating piece 20 e of the member 20 and is accommodated in the main body attachment member 20. When the suspension member 32 is brought into contact with the upper side of the support member 23 and the nuts 24 on both sides are manually tightened, the support member 23 comes into contact with the front arm metal holding member 20c and is fixed together with the suspension member 32. Further, the shaft portion 31 of the suspension member 32 is abutted and fixed to the inner surfaces of the both bearing holes 20b.

以上、説明した実施形態によれば、以下の作用効果を奏することができる。
(1)吊部材32の吊部33が支え部材23の上方、且つ一対の吊下げボルト22の間隙の中央に位置するとともに、吊部33の上部が一対の吊下げボルト22の先端以下の高さに位置する。このため、吊部材32の吊部33の高さを抑えることができるので、開閉器1の高さが高くなることはない。よって、開閉器1を吊り上げる際に電線が既に架設されている場合でも所定の位置に配置することができ、電柱上の腕金への取り付け作業が容易となる。
As described above, according to the embodiment described above, the following effects can be obtained.
(1) The suspension part 33 of the suspension member 32 is located above the support member 23 and in the center of the gap between the pair of suspension bolts 22, and the upper part of the suspension part 33 is higher than the tip of the pair of suspension bolts 22. Located in. For this reason, since the height of the suspension part 33 of the suspension member 32 can be suppressed, the height of the switch 1 does not increase. Therefore, even when the electric wire has already been erected when lifting the switch 1, it can be arranged at a predetermined position, and the attachment work to the armrest on the utility pole becomes easy.

(2)操作ハンドル10(正面1a)から見て、吊部材32の吊部33の中心Pが開閉器1本体の重心Gの鉛直上方に位置する。このため、電柱上の腕金15への取り付け作業時に開閉器1の左右方向、すなわち開閉器1の正面1aに対して垂直方向となるブッシング11,12がそれぞれ突設された両側面1d,1e方向に傾くことを抑制することができ、安定して吊下げることができる。よって、開閉器1を容易に取り付けることができる。   (2) When viewed from the operation handle 10 (front surface 1a), the center P of the suspension portion 33 of the suspension member 32 is positioned vertically above the center of gravity G of the switch 1 body. For this reason, the both side surfaces 1d and 1e from which the bushings 11 and 12 which protrude in the left-right direction of the switch 1 at the time of attachment work to the metal brace 15 on the utility pole, that is, perpendicular to the front surface 1a of the switch 1 are respectively provided. Inclination in the direction can be suppressed and can be stably suspended. Therefore, the switch 1 can be easily attached.

(3)吊部材32が吊部33、両吊下げボルト22を軸支する軸部31、吊部33及び軸部31を接続する接続部34を一体に形成されてなるようにしたため、吊部33と軸部31を別部材で設ける必要がない。よって、部品点数を少なくすることができ、安価にすることができる。また、吊部材32は軸部31により起伏可能に軸支されるため、使用しない際には収容することができ、小型化することができる。   (3) Since the suspension member 32 is formed integrally with the suspension portion 33, the shaft portion 31 that pivotally supports both suspension bolts 22, the suspension portion 33, and the connection portion 34 that connects the shaft portion 31, the suspension portion There is no need to provide 33 and the shaft portion 31 as separate members. Therefore, the number of parts can be reduced and the cost can be reduced. Moreover, since the suspension member 32 is pivotally supported by the shaft portion 31 so that it can be raised and lowered, it can be accommodated when not in use and can be reduced in size.

(4)本体取付部材20の両側壁20aの両軸受孔20bに挿通するとともに、2本の吊下げボルト22は回動可能に吊部材32の軸部31に取り付けるようにした。これにより、部品点数を削減できるので、安価にでき、軽量化することもできる。   (4) The two suspension bolts 22 are rotatably attached to the shaft portion 31 of the suspension member 32 while being inserted into both bearing holes 20b of the both side walls 20a of the body attachment member 20. Thereby, since the number of parts can be reduced, it can be made cheap and can also be reduced in weight.

(5)吊部材32の吊部33及び接続部34は、電柱上の腕金15を本体取付部材20及び支え部材23により吊下げ挟持した際、吊下げボルト22に接触しないよう吊下げボルト22に対して傾いて形成されているため、吊下げた際に吊部材32の吊部33及び接続部34が吊下げボルト22と接触することを抑制することができる。これにより、吊部材32と吊下げボルト22との接触による損傷を抑制することができる。   (5) The suspension part 33 and the connection part 34 of the suspension member 32 are suspended from the suspension bolt 22 so as not to come into contact with the suspension bolt 22 when the arm metal 15 on the utility pole is suspended and held by the main body attachment member 20 and the support member 23. Therefore, it is possible to prevent the suspension portion 33 and the connection portion 34 of the suspension member 32 from coming into contact with the suspension bolt 22 when suspended. Thereby, damage due to contact between the suspension member 32 and the suspension bolt 22 can be suppressed.

具体的には、接続部34の鉛直部34aが吊下げボルト22に対して開閉器1の後方へ傾くとともに、吊部33を、吊下げボルト22に対して開閉器1の前方へ傾くように形成したため、開閉器1を腕金15に取り付けた際の吊下げボルト22の立設時に、吊部材32の鉛直部34aと右側の吊下げボルト22との接触を抑制することができる。よって、右側の吊下げボルト22及び吊部材32の接触による損傷を抑制できるとともに、開閉器1の取り付け作業が容易となる。   Specifically, the vertical portion 34 a of the connecting portion 34 is inclined to the rear of the switch 1 with respect to the suspension bolt 22, and the suspension portion 33 is inclined to the front of the switch 1 with respect to the suspension bolt 22. Since it formed, the contact with the vertical part 34a of the suspension member 32 and the right suspension bolt 22 can be suppressed when the suspension bolt 22 is erected when the switch 1 is attached to the arm metal 15. Therefore, damage due to contact between the right suspension bolt 22 and the suspension member 32 can be suppressed, and the switch 1 can be easily attached.

また、吊部材32の吊部33の先端部を吊下げボルト22と同一直線上に位置させるとともに、両吊下げボルト22の間隙の中央に位置させているため、電柱上の腕金15への取り付け作業時に吊下げボルト22を容易に立設させることができる。よって、開閉器1の腕金15への取り付け作業が容易となる。   Moreover, since the front-end | tip part of the suspension part 33 of the suspension member 32 is located in the same straight line as the suspension bolt 22, and is located in the center of the clearance gap between both suspension bolts 22, The suspension bolt 22 can be easily erected at the time of attachment work. Therefore, the attachment work to the arm bracket 15 of the switch 1 becomes easy.

(6)吊下げボルト22の支え部材23とナット24との間には、下端が支え部材23の上面に接し、上端が吊部材32の接続部34より上方に位置するスペーサ25が環装されているため、ナット24の取り付け位置が吊部材32の接続部34より上方に位置する。これにより、開閉器1を電柱上の腕金15に取り付けたり、取り外したりする際にナット24を回動するラチェット工具が吊部材32の接続部34に接触することを抑制することができる。   (6) Between the support member 23 and the nut 24 of the suspension bolt 22, a spacer 25 whose lower end is in contact with the upper surface of the support member 23 and whose upper end is located above the connection portion 34 of the suspension member 32 is mounted. Therefore, the attachment position of the nut 24 is located above the connection portion 34 of the suspension member 32. Thereby, it is possible to suppress the ratchet tool that rotates the nut 24 from contacting the connecting portion 34 of the suspension member 32 when the switch 1 is attached to or removed from the arm metal 15 on the utility pole.

(7)両側壁20a、前側腕金保持部材20c、後側腕金保持部材20fの高さ寸法を支え部材23の幅寸法と同一寸法に形成したため、本体取付部材20に収納した際、本体取付部材20から上方へ突出しない。よって、開閉器1の全高寸法を抑えることができるので、小型化することができる。   (7) Since the height dimensions of the side walls 20a, the front arm metal holding member 20c, and the rear arm metal holding member 20f are the same as the width dimension of the support member 23, when the main body mounting member 20 is stored, It does not protrude upward from the member 20. Therefore, since the overall height of the switch 1 can be suppressed, the size can be reduced.

(8)本体取付部材20の前端に規制片20eが前方へ延出するようにし吊下げボルト22及び支え部材23を当接するようにし、吊部材32を支え部材23の上方に位置して収納するようにした。このため、吊部材32、吊下げボルト22、及び支え部材23が開閉器1に当接することがない。よって、開閉器1を損傷することがない。   (8) The restriction piece 20e extends forward at the front end of the main body attachment member 20, the suspension bolt 22 and the support member 23 are brought into contact with each other, and the suspension member 32 is positioned above the support member 23 and stored. I did it. For this reason, the suspension member 32, the suspension bolt 22, and the support member 23 do not contact the switch 1. Therefore, the switch 1 is not damaged.

(9)収納時において支え部材23を規制片20eに当接するようにし、ナット24を手で締め付けることにより、前側腕金保持部材20cに当接固定するようにしたため、支え部材23を容易に固定できるとともに、輸送時に外れることを防止できる。   (9) Since the support member 23 is brought into contact with the regulating piece 20e during storage and the nut 24 is tightened by hand, the support member 23 is contacted and fixed to the front armrest holding member 20c. In addition, it can be prevented from coming off during transportation.

(10)収納時においてナット24を手で締め付けることにより、吊部材32の軸部31が両軸受孔20bの内面に当接固定するようにしたため、輸送時に吊部材32が揺動することがない。   (10) Since the nut portion 24 is manually tightened during storage so that the shaft portion 31 of the suspension member 32 contacts and is fixed to the inner surfaces of both bearing holes 20b, the suspension member 32 does not swing during transportation. .

(11)本体取付部材20の前側腕金保持部材20c及び後側腕金保持部材20fに凹部20dと凹部20gとをそれぞれ形成したため、開閉器1を腕金15に取り付ける際に、腕金15を位置決めでき容易に取り付けできるとともに、開閉器1のずれを防止できる。   (11) Since the concave portion 20d and the concave portion 20g are formed in the front side arm metal holding member 20c and the rear side arm metal holding member 20f of the main body attaching member 20, respectively, when attaching the switch 1 to the arm metal 15, Positioning and easy attachment are possible, and displacement of the switch 1 can be prevented.

(12)吊部材32の水平部34bを支え部材23より上部で、且つナット24より下部の間で水平に延びるように形成したため、開閉器1を腕金15に取り付ける際に、右側の吊下げボルト22を水平部34bに当接させて仮置きしておくことができる。このため、右側の吊下げボルト22を立設に近い状態に保持しておくことができるので、支え部材23の係合が容易となる。よって、開閉器1の腕金15への取り付け作業が容易となる。   (12) Since the horizontal portion 34b of the suspension member 32 is formed so as to extend horizontally above the support member 23 and between the lower portion of the nut 24, when the switch 1 is attached to the brace 15, The bolt 22 can be temporarily placed in contact with the horizontal portion 34b. For this reason, since the right suspension bolt 22 can be held in a state close to standing, the support member 23 can be easily engaged. Therefore, the attachment work to the arm bracket 15 of the switch 1 becomes easy.

(第2の実施形態)
以下、本発明にかかる配電機器の取付装置を開閉器に具体化した第2の実施形態について、図3を参照して説明する。この実施形態の開閉器1の取付装置4は、吊部材42の形状と、吊部材42の連結構造が上記第1の実施形態と異なっている。以下、第1の実施形態との相違点を中心に説明する。
(Second Embodiment)
Hereinafter, a second embodiment in which the distribution device mounting device according to the present invention is embodied as a switch will be described with reference to FIG. 3. The mounting device 4 of the switch 1 according to this embodiment is different from the first embodiment in the shape of the suspension member 42 and the connection structure of the suspension member 42. Hereinafter, a description will be given focusing on differences from the first embodiment.

図3(a)に示されるように、吊部材42は、環状の吊部43と、吊部43及び右側の吊下げボルト22に連結される接続部44とから構成されてなる。接続部44の吊部43と反対側の端部は、右側の吊下げボルト22の支え部材23より上部で、且つナット24より下部に連結固定されている。吊部材42は、単一の棒材が湾曲されることにより一体に形成されている。   As shown in FIG. 3A, the suspension member 42 includes an annular suspension portion 43 and a connection portion 44 coupled to the suspension portion 43 and the right suspension bolt 22. The end of the connection portion 44 opposite to the suspension portion 43 is connected and fixed above the support member 23 of the right suspension bolt 22 and below the nut 24. The suspension member 42 is integrally formed by bending a single bar.

詳しくは、吊部材42の接続部44は、一端が右側の吊下げボルト22と左側の吊下げボルト22とが対向する部位に接続され、左側へ水平に延び、他端が両吊下げボルト22の中間位置で吊部43に連結されている。吊部材42の吊部43は、先端部が吊下げボルト22と同一直線上に位置するとともに、両吊下げボルト22の間隙の中央に位置している。また、吊部材42の吊部43は、支え部材23の上方に位置するとともに、吊部材42の吊部43の頂部、すなわち吊部43の上部は、両吊下げボルト22の上方先端以下の高さに設定されている。   Specifically, one end of the connection portion 44 of the suspension member 42 is connected to a portion where the right suspension bolt 22 and the left suspension bolt 22 face each other, extends horizontally to the left, and the other end of the suspension bolts 22. It is connected with the suspension part 43 in the intermediate position. The suspending portion 43 of the suspending member 42 has a distal end located on the same straight line as the suspending bolt 22 and is located at the center of the gap between the both suspended bolts 22. In addition, the suspension portion 43 of the suspension member 42 is located above the support member 23, and the top of the suspension portion 43 of the suspension member 42, that is, the upper portion of the suspension portion 43 is not higher than the upper tip of the suspension bolts 22. Is set.

これに伴い、右側のスペーサ26は、接続部44を避けるように接続部44の径に合わせた開口部が形成され、横断面形状がC字状の管となっている。右側のスペーサ26の長さは、上端が吊部材42の接続部44より上方に位置するようになっている。右側のナット24が締め付けられることにより右側のスペーサ26が移動する際は、接続部44の接続部分が右側のスペーサ26の隙間を通過することができる。なお、左側のスペーサ25は、円筒状で右側のスペーサ26と同じ長さとなっている。吊部材42は、右側の吊下げボルト22とともに軸部材41を回動中心として回動する。   Along with this, the right spacer 26 is formed with an opening corresponding to the diameter of the connecting portion 44 so as to avoid the connecting portion 44, and is a tube having a C-shaped cross section. The length of the right spacer 26 is such that the upper end is located above the connecting portion 44 of the suspension member 42. When the right spacer 26 moves by tightening the right nut 24, the connecting portion of the connecting portion 44 can pass through the gap of the right spacer 26. The left spacer 25 is cylindrical and has the same length as the right spacer 26. The suspension member 42 rotates around the shaft member 41 as a rotation center together with the right suspension bolt 22.

本体取付部材20は、両側部としての両側壁20aが形成され、両側壁20aに軸受孔20bがそれぞれ形成されている。2本の吊下げボルト22は、本体取付部材20の両側壁20aの両軸受孔20bに挿通された軸部材41に回動可能に取り付けられている。   The body mounting member 20 has both side walls 20a as both side portions, and bearing holes 20b are formed in the both side walls 20a. The two suspension bolts 22 are rotatably attached to a shaft member 41 inserted through both bearing holes 20b of both side walls 20a of the main body attachment member 20.

図3(a)、(b)に示されるように、操作ハンドル10(正面1a)及び側面1dから見て、吊部43の円の中心Pが開閉器1本体の重心Gの鉛直上方に位置している。
次に、前述のように構成された開閉器1の取付装置4の操作態様について説明する。
As shown in FIGS. 3A and 3B, the center P of the circle of the hanging portion 43 is positioned vertically above the center of gravity G of the main body of the switch 1 when viewed from the operation handle 10 (front surface 1a) and the side surface 1d. is doing.
Next, an operation mode of the mounting device 4 of the switch 1 configured as described above will be described.

図3(b)に二点鎖線で示されるように、開閉器1の輸送時には、取付装置4は、両側の吊下げボルト22及び吊部材42が本体取付部材20の上面に対して平行となるように軸部材41を回動中心として回動し、収納された状態とされる。この際、吊下げボルト22に取り付けられている支え部材23は、本体取付部材20の規制片20eに当接し、前側腕金保持部材20cよりも外側に位置している。そして、支え部材23は、両側のナット24が手で締め付けられ、前側腕金保持部材20cの外側面に押し付けられることにより固定されている。   As shown by a two-dot chain line in FIG. 3B, when the switch 1 is transported, the mounting device 4 has the suspension bolts 22 and the suspension members 42 on both sides parallel to the upper surface of the body attachment member 20. As described above, the shaft member 41 is rotated about the rotation center, and is stored. At this time, the support member 23 attached to the suspension bolt 22 is in contact with the restriction piece 20e of the main body attachment member 20 and is located on the outer side of the front arm metal holding member 20c. The support member 23 is fixed by tightening the nuts 24 on both sides by hand and pressing it against the outer surface of the front armrest holding member 20c.

開閉器1を電柱上の腕金15に取り付ける際には、両側のナット24を緩め、吊部材42とともに吊下げボルト22が軸部材41に対して回動可能な状態とする。また、固定金具29を支え部材23から外すとともに、右側の吊下げボルト22から支え部材23の溝23bを外し、支え部材23を吊下げボルト22に対して回動可能な状態とする。吊下げボルト22及び吊部材42を開閉器1の背面1c側へ回動させ、吊部材42、すなわち右側の吊下げボルト22を立設させる。そして、クレーン等のフックを吊部材42の吊部43に引っ掛け電柱上まで持ち上げる。図3(a)に示されるように、腕金15を本体取付部材20の凹部20d,20gと支え部材23との間に挟み、ナット24をラチェット工具により締め付けることにより開閉器1が電柱上の腕金15に取り付けられる。この際、スペーサ25,26が吊下げボルト22の支え部材23とナット24との間に環装されているため、ラチェット工具の回動範囲に吊部材42の接続部44がなく、接触することを抑制することができる。   When attaching the switch 1 to the arm metal 15 on the utility pole, the nuts 24 on both sides are loosened so that the suspension bolts 22 and the suspension bolts 22 can rotate with respect to the shaft member 41. Further, the fixing bracket 29 is removed from the support member 23, and the groove 23 b of the support member 23 is removed from the right suspension bolt 22, so that the support member 23 can be rotated with respect to the suspension bolt 22. The suspension bolt 22 and the suspension member 42 are rotated to the back surface 1c side of the switch 1, and the suspension member 42, that is, the right suspension bolt 22 is erected. And hooks, such as a crane, are hooked on the suspension part 43 of the suspension member 42, and it lifts up on a utility pole. As shown in FIG. 3A, the armature 15 is sandwiched between the recesses 20d and 20g of the main body mounting member 20 and the support member 23, and the nut 24 is tightened with a ratchet tool so that the switch 1 is mounted on the utility pole. Attached to the brace 15. At this time, since the spacers 25 and 26 are mounted between the support member 23 of the suspension bolt 22 and the nut 24, the connection portion 44 of the suspension member 42 is not in contact with the rotation range of the ratchet tool. Can be suppressed.

開閉器1を電柱上の腕金15から取り外す際には、吊部材42の吊部43にクレーン等のフックを引っ掛け、開閉器1を持ち上げ、ナット24をラチェット工具により緩め、開閉器1を腕金15から取り外す。そして、開閉器1が地面に下ろされると、図3(b)に二点鎖線で示されるように、吊下げボルト22及び吊部材42は開閉器1の前側へ回動され、本体取付部材20の規制片20eに支え部材23が当接した状態で、本体取付部材20に収納される。両側のナット24を手で締め付けると、支え部材23が前側腕金保持部材20cに接触し固定される。   When the switch 1 is removed from the arm bracket 15 on the utility pole, a hook such as a crane is hooked on the suspension portion 43 of the suspension member 42, the switch 1 is lifted, the nut 24 is loosened with a ratchet tool, and the switch 1 is armed. Remove from gold 15. When the switch 1 is lowered to the ground, as shown by a two-dot chain line in FIG. 3B, the suspension bolt 22 and the suspension member 42 are rotated to the front side of the switch 1, and the main body attachment member 20. The support member 23 is in contact with the regulating piece 20e and is accommodated in the main body attachment member 20. When the nuts 24 on both sides are tightened by hand, the support member 23 comes into contact with and is fixed to the front armrest holding member 20c.

以上、説明した実施形態によれば、第1の実施形態の(2)、(7)、(8)、及び(11)の作用効果に加え、以下の作用効果を奏することができる。
(13)吊部材42の吊部43を支え部材23の上方、且つ一対の吊下げボルト22の間隙の中央に位置するとともに、吊部43の上部が一対の吊下げボルト22の先端以下の高さに位置する。このため、吊部材42の吊部43の高さを抑えることができるので、開閉器1の高さが高くなることはない。よって、開閉器1を吊り上げる際に電線が既に架設されている場合でも所定の位置に配置することのでき、電柱上の腕金への取り付け作業が容易となる。
As described above, according to the embodiment described above, in addition to the effects (2), (7), (8), and (11) of the first embodiment, the following effects can be achieved.
(13) The suspension portion 43 of the suspension member 42 is positioned above the support member 23 and in the center of the gap between the pair of suspension bolts 22, and the upper portion of the suspension portion 43 is higher than the tip of the pair of suspension bolts 22. Located in. For this reason, since the height of the suspension part 43 of the suspension member 42 can be suppressed, the height of the switch 1 does not increase. Therefore, even when the electric wire has already been installed when lifting the switch 1, it can be arranged at a predetermined position, and the attachment work to the armrest on the utility pole becomes easy.

(14)吊部43と、吊部43及び吊下げボルト22の間を連結する接続部44とが一体形成されてなる吊部材42を備えるため、部品点数を少なくすることができる。また、吊部材42を起伏可能に軸部材41に軸支された吊下げボルト22の支え部材23より上部に一体に連結固定するようにし、吊部材42の吊部43の先端部を吊下げボルト22と同一直線上に位置させているため、電柱上の腕金15への取り付け作業時に吊部43にて吊り上げるだけで、右側の吊下げボルト22を容易に立設させることができる。よって、開閉器1の取り付け作業が容易となる。そして、使用しない際には右側の吊下げボルト22とともに倒しておくことができ、小型化することができる。   (14) Since the suspension member 42 formed by integrally forming the suspension portion 43 and the connection portion 44 that connects the suspension portion 43 and the suspension bolt 22 is provided, the number of components can be reduced. Further, the suspension member 42 is integrally connected and fixed above the support member 23 of the suspension bolt 22 pivotally supported by the shaft member 41 so that the suspension member 42 can be raised and lowered, and the distal end portion of the suspension portion 43 of the suspension member 42 is suspended from the suspension bolt. 22, the right suspension bolt 22 can be easily erected simply by lifting the suspension portion 43 during the attachment work to the arm metal 15 on the utility pole. Therefore, the installation work of the switch 1 becomes easy. And when not in use, it can be brought down together with the right hanging bolt 22 and can be miniaturized.

(15)吊下げボルト22の支え部材23とナット24との間には、下端が支え部材23の上面に接し、上端が吊部材42の接続部44より上方に位置するスペーサ25,26が環装されているため、ナット24の取り付け位置が吊部材42の接続部44より上方に位置する。これにより、開閉器1を電柱上の腕金15に取り付けたり、取り外したりする際にナット24を回動するラチェット工具が吊部材42の接続部44に接触することを抑制することができる。   (15) Between the support member 23 and the nut 24 of the suspension bolt 22, spacers 25 and 26 whose lower end is in contact with the upper surface of the support member 23 and whose upper end is located above the connection portion 44 of the suspension member 42 are annular. Therefore, the mounting position of the nut 24 is located above the connection portion 44 of the suspension member 42. Thereby, it is possible to prevent the ratchet tool that rotates the nut 24 from contacting the connecting portion 44 of the suspension member 42 when the switch 1 is attached to or removed from the arm metal 15 on the utility pole.

Then, it extends upward from the support member 23, and then horizontally extends to the left between the upper portion of the support member 23 and the lower portion of the nut 24, and is connected to the suspension portion 53 at an intermediate position between the suspension bolts 22. The suspension portion 53 of the suspension member 52 is located above the support member 23 and is located at the center of the gap between the suspension bolts 22. Further, the top of the suspension part 53 of the suspension member 52, that is, the upper part of the suspension part 53 is set to a height equal to or lower than the upper ends of both suspension bolts 22. The suspension member 52 rotates around the shaft member 51 together with the right suspension bolt 22.

図4(a)及び(b)に示されるように、操作ハンドル10(正面1a)及び側面1dから見て、吊部53の円の中心Pが開閉器1本体の重心Gの鉛直上方に位置している。
次に、前述のように構成された開閉器1の取付装置5の操作態様について説明する。
As shown in FIGS. 4A and 4B, the center P of the circle of the hanging portion 53 is positioned vertically above the center of gravity G of the main body of the switch 1 when viewed from the operation handle 10 (front surface 1a) and the side surface 1d. is doing.
Next, an operation mode of the mounting device 5 for the switch 1 configured as described above will be described.

And hooks, such as a crane, are hooked on the suspension part 53 of the suspension member 52, and it lifts up on a utility pole. As shown in FIG. 4A, the switch 1 is attached to the arm metal 15 on the power pole by sandwiching the arm metal 15 between the main body attachment member 20 and the support member 23 and tightening the nut 24 with a ratchet tool. It is done. At this time, since the spacer 25 is between the support member 23 of the suspension bolt 22 and the nut 24, there is no connection portion 54 of the suspension member 52 in the rotation range of the ratchet tool, and contact can be prevented. .

開閉器1を電柱上の腕金15から取り外す際には、吊部材52の吊部53にクレーン等のフックを引っ掛け、開閉器1を持ち上げ、ナット24をラチェット工具により緩め、開閉器1を腕金15から取り外す。そして、開閉器1が地面に下ろされると、図4(b)に二点鎖線で示されるように、吊下げボルト22及び吊部材52は開閉器1の前側へ回動され、本体取付部材20の規制片20eに支え部材23が当接した状態で、本体取付部材20に収納される。両側のナット24を手で締め付けると、支え部材23が前側腕金保持部材20cに接触し固定される。   When the switch 1 is removed from the arm bracket 15 on the utility pole, a hook such as a crane is hooked on the suspension portion 53 of the suspension member 52, the switch 1 is lifted, the nut 24 is loosened with a ratchet tool, and the switch 1 is armed. Remove from gold 15. When the switch 1 is lowered to the ground, as shown by a two-dot chain line in FIG. 4B, the suspension bolt 22 and the suspension member 52 are rotated to the front side of the switch 1, and the main body attachment member 20. The support member 23 is in contact with the regulating piece 20e and is accommodated in the main body attachment member 20. When the nuts 24 on both sides are tightened by hand, the support member 23 comes into contact with and is fixed to the front armrest holding member 20c.

以上、説明した実施形態によれば、第1の実施形態の(2)、(6)、(7)、(8)、及び(11)の作用効果に加え、以下の作用効果を奏することができる。
(16)吊部材52の吊部53を支え部材23の上方、且つ一対の吊下げボルト22の間隙の中央に位置するとともに、吊部53の上部が一対の吊下げボルト22の先端以下の高さに位置する。このため、吊部材52の吊部53の高さを抑えることができるので、開閉器1の高さが高くなることはない。よって、開閉器1を吊り上げる際に電線が既に架設されている場合でも所定の位置に配置することのでき、電柱上の腕金への取り付け作業が容易となる。
As described above, according to the embodiment described above, in addition to the effects of (2), (6), (7), (8), and (11) of the first embodiment, the following effects can be achieved. it can.
(16) The suspension portion 53 of the suspension member 52 is positioned above the support member 23 and in the center of the gap between the pair of suspension bolts 22, and the upper portion of the suspension portion 53 is higher than the tip of the pair of suspension bolts 22. Located in. For this reason, since the height of the suspension part 53 of the suspension member 52 can be suppressed, the height of the switch 1 does not increase. Therefore, even when the electric wire has already been installed when lifting the switch 1, it can be arranged at a predetermined position, and the attachment work to the armrest on the utility pole becomes easy.

(17)吊部53と、吊部53及び吊下げボルト22の間を連結する接続部54とが一体形成されてなる吊部材52を備えるため、部品点数を少なくすることができる。また、吊部材52を起伏可能に軸部材51に軸支された吊下げボルト22の支え部材23より下部に一体に連結固定するようにしたため、電柱上の腕金15への取り付け作業時に吊部53にて吊り上げるだけで、右側の吊下げボルト22を容易に立設させることができる。よって、開閉器1の取り付け作業が容易となる。そして、使用しない際には右側の吊下げボルト22とともに倒しておくことができ、小型化することができる。   (17) Since the suspension member 52 formed by integrally forming the suspension portion 53 and the connection portion 54 that connects the suspension portion 53 and the suspension bolt 22 is provided, the number of components can be reduced. Further, since the suspension member 52 is integrally connected and fixed below the support member 23 of the suspension bolt 22 that is pivotally supported by the shaft member 51 so that the suspension member 52 can be raised and lowered, the suspension portion is attached to the arm metal 15 on the utility pole. The suspension bolt 22 on the right side can be easily erected only by lifting at 53. Therefore, the installation work of the switch 1 becomes easy. And when not in use, it can be brought down together with the right hanging bolt 22 and can be miniaturized.

The connecting portion 64 is pivotally supported by the member 61 so as to be raised and lowered. A shaft hole 64a through which the shaft member 61 can be inserted is formed at the end of the connection portion 64 opposite to the hanging portion 63, and the shaft member 61 is inserted into and supported by the shaft hole 64a. The two suspension bolts 22 are rotatably attached to the inner side of each side wall 20a of the main body attachment member 20 by a shaft member 61, and the suspension member 62 has a portion bent at the left side of the connection portion 64 at the right side. The bolt 22 is attached so as to be positioned on the back surface 1c side. The shaft member 61 inserted into both the bearing holes 20b of the side wall 20a of the main body mounting member 20 is prevented from coming off by screwing a metal fitting such as a pin and a nut 65 to the outside of the both side walls 20a.

吊部材62は、単一の板材が折曲されることにより一体に形成されている。詳しくは、吊部材62の接続部64は、長方形の板材が前側方向と左側方向との90度に折り曲げられ、接続部64の頂部64bは、支え部材23より上部で、且つナット24より下部の位置に形成されている。接続部64は、前側方向へ折り曲げられた部分の下側に軸孔64aが形成され、左側方向へ折り曲げられた部分の頂部64bの上側に吊部63が接続されている。吊部材62の吊部63は、吊下げボルト22の背面1c側で、支え部材23の上方に位置するとともに、両吊下げボルト22の間隙の中央に位置している。また、吊部材52の吊部53の頂部、すなわち吊部53の上部は、両吊下げボルト22の上端以下の高さに設定されている。吊部材62は、軸部材61を回動中心として回動する。   The suspension member 62 is integrally formed by bending a single plate material. Specifically, the connecting portion 64 of the suspension member 62 is formed by bending a rectangular plate material at 90 degrees in the front side direction and the left side direction, and the top portion 64b of the connecting portion 64 is above the support member 23 and below the nut 24. Formed in position. The connecting portion 64 has a shaft hole 64a formed below the portion bent in the front direction, and the hanging portion 63 connected to the upper side of the top portion 64b of the portion bent in the left direction. The suspension part 63 of the suspension member 62 is located above the support member 23 on the back surface 1 c side of the suspension bolt 22 and is located at the center of the gap between the suspension bolts 22. Further, the top of the suspension part 53 of the suspension member 52, that is, the upper part of the suspension part 53 is set to a height equal to or lower than the upper ends of both suspension bolts 22. The suspension member 62 rotates about the shaft member 61 as a rotation center.

図5(b)に示されるように、本体取付部材20の右側の側壁20aには、接続部64の左側方向へ折り曲げられた部分の下部が収容される溝部20hが形成されている。図(a)、(b)に示されるように、操作ハンドル10(正面1a)及び側面1dから見て、吊部63の孔の中心Pが開閉器1本体の重心Gの鉛直上方に位置している。   As shown in FIG. 5B, the right side wall 20 a of the body attachment member 20 is formed with a groove 20 h that accommodates the lower portion of the connection portion 64 bent in the left direction. As shown in FIGS. 1A and 1B, the center P of the hole of the hanging portion 63 is located vertically above the center of gravity G of the main body of the switch 1 when viewed from the operation handle 10 (front surface 1a) and the side surface 1d. ing.

次に、前述のように構成された開閉器1の取付装置6の操作態様について説明する。
図5(b)に二点鎖線で示されるように、開閉器1の輸送時には、取付装置6は、両側の吊下げボルト22及び吊部材62が本体取付部材20の上面に対して平行となるように軸部材61を回動中心として回動し、収納された状態とされる。この際、吊下げボルト22に取り付けられている支え部材23は、本体取付部材20の規制片20eに当接し、前側腕金保持部材20cよりも外側に位置している。そして、支え部材23は、両側のナット24が手で締め付けられることにより、前側腕金保持部材20cの外側面に押し付けられることにより固定されている。
Next, an operation mode of the mounting device 6 for the switch 1 configured as described above will be described.
As shown by a two-dot chain line in FIG. 5B, when the switch 1 is transported, the attachment device 6 has the suspension bolts 22 and the suspension members 62 on both sides parallel to the upper surface of the body attachment member 20. As described above, the shaft member 61 is rotated about the rotation center, and is stored. At this time, the support member 23 attached to the suspension bolt 22 is in contact with the restriction piece 20e of the main body attachment member 20 and is located on the outer side of the front arm metal holding member 20c. The support member 23 is fixed by being pressed against the outer surface of the front armrest holding member 20c by manually tightening the nuts 24 on both sides.

開閉器1を電柱上の腕金15に取り付ける際には、吊下げボルト22及び吊部材62を開閉器1の背面1c側へ回動させ、吊部材62を立設させる。そして、クレーン等のフックを吊部材62の吊部63に引っ掛け電柱上まで持ち上げる。   When attaching the switch 1 to the arm metal 15 on the utility pole, the suspension bolt 22 and the suspension member 62 are rotated to the back surface 1c side of the switch 1, and the suspension member 62 is erected. And hooks, such as a crane, are hooked on the suspension part 63 of the suspension member 62, and it lifts up on a utility pole.

図5(a)に示されるように、腕金15を本体取付部材20の凹部20d,20gに当接させ、右側の吊下げボルト22を開閉器1の背面1c側へ回動させる。この時、右側の吊下げボルト22を吊部材62の接続部64の頂部64bに当接させ仮置きしておく。なお、接続部64の頂部64bは仮置部を構成する。そして、左側の吊下げボルト22を開閉器1の背面1c側へ回動させた後、支え部材23を回動させ、支え部材23の溝23b内に右側の吊下げボルト22を挿入し、固定金具29を支え部材23に係合させる。これにより、本体取付部材20の凹部20d,20gと支え部材23との間に腕金15を挟み、ナット24をラチェット工具により締め付けることにより開閉器1が電柱上の腕金15に取り付けられる。この際、スペーサ25が吊下げボルト22の支え部材23とナット24との間にあるため、ラチェット工具の回動範囲に吊部材62の接続部64がなく、接触することを防止することができる。   As shown in FIG. 5A, the arm metal 15 is brought into contact with the recesses 20 d and 20 g of the main body mounting member 20, and the right suspension bolt 22 is rotated toward the back surface 1 c of the switch 1. At this time, the right suspension bolt 22 is temporarily placed in contact with the top portion 64 b of the connection portion 64 of the suspension member 62. In addition, the top part 64b of the connection part 64 comprises a temporary placement part. Then, after the left suspension bolt 22 is rotated to the back surface 1c side of the switch 1, the support member 23 is rotated, and the right suspension bolt 22 is inserted into the groove 23b of the support member 23 and fixed. The metal fitting 29 is engaged with the support member 23.
