Description

本発明は、柱上に設置されるトランス等の機器を位置調整自在に吊り上げるために電柱に組み付けられる柱装吊上装置に関する。   The present invention relates to a pole-mounted lifting device that is assembled to a power pole in order to lift a device such as a transformer installed on a pole in a position-adjustable manner.

トランスのような重量のある電気機器を電柱に取り付ける場合、図示は省略するが、例えば、クレーン車によってトランスを吊り上げて電柱側に設けたハンガー座（又は腕金に設けた座板）等の機器設置対象物（又は場所）に移動させる一方、高所作業車等に搭乗した作業員が設置対象物に対してトランスを位置合わせをして締結部材等によって固定するようにしていた。   When a heavy electrical device such as a transformer is attached to the utility pole, illustration is omitted, but for example, a device such as a hanger seat (or a seat plate provided on a brace) provided on the utility pole side by lifting the transformer by a crane truck While moving to an installation object (or place), an operator who has boarded an aerial work vehicle or the like aligns the transformer with the installation object and fixes it with a fastening member or the like.

また、障害物の存在等の周囲条件によってクレーン車や高所作業車を導入できない場合やこれらの車両を手配できない場合等に使用されるトランスホイストも提案されている（例えば、特許文献１参照）。そのトランスホイストは、予め回動アームを適切な角度に固定した後、その回動アームに設けた滑車に吊り上げ用のワイヤロープを掛けてウインチ等でトランスを吊り上げておき、作業者がトランスを電柱に設けられているハンガー座（又は腕金に設けた座板）等の機器設置対象物（又は場所）に対して位置合わせをして締結部材等によって固定するように使用される。
実開平６−１７３０７号公報 In addition, a transformer hoist has been proposed that is used when a crane vehicle or an aerial work vehicle cannot be introduced due to ambient conditions such as the presence of an obstacle or when these vehicles cannot be arranged (see, for example, Patent Document 1). . In the transformer hoist, after the rotating arm is fixed at an appropriate angle in advance, a wire rope for lifting is hung on a pulley provided on the rotating arm and the transformer is lifted by a winch or the like. It is used to align with a device installation object (or place) such as a hanger seat (or a seat plate provided on the armrest) provided on the armature and fix it with a fastening member or the like.
Japanese Utility Model Publication No. 6-17307

しかし、従来のトランスホイストは、吊り上げた状態ではトランスを任意に移動させることができなかったため、トランスをハンガーに掛止させる際に、作業者が、ハンガーに対して、トランスを腕力により斜め上方から強引に落し込むようにして掛止させていたが、その作業は大変な労力と時間を必要としていた。また、トランスを吊り上げる過程で架線等の障害物を避けなければならないこともあったが、その際にも、例えば、トラ綱等を使用して多くの労力と時間を必要としていた。   However, in the conventional transformer hoist, the transformer could not be moved arbitrarily in the lifted state. Therefore, when the transformer is hooked on the hanger, the operator can lift the transformer against the hanger from the upper side by the arm force. Although it was forced to drop, the work required a lot of labor and time. In addition, obstacles such as overhead wires have to be avoided in the process of lifting the transformer, but at that time, for example, a tiger rope is used and much labor and time are required.

本発明は、このような実情に鑑みてなされ、柱上に設置されるトランス等の電気機器を位置調整自在に吊り上げることができる柱装吊上装置を提供することを目的とする。   This invention is made | formed in view of such a situation, and it aims at providing the column mounting lifting apparatus which can lift up electric equipments, such as a transformer installed on a pillar, so that position adjustment is possible.

以下に、本発明の最良の実施の形態に係る柱装吊上装置について図面を参照しつつ詳細に説明する。
図１は柱装吊上装置によってトランスを限度まで吊り上げている状態の斜視図、図２（ａ）は柱装吊上装置の平面図、（ｂ）は側面図、（ｃ）は正面図である。これらの図にて、符号１は電柱、２は、電柱１に着脱自在に取り付けられる柱取付部材、３は、略水平方向に延びるアーム部材で、その基部が柱取付部材２に回動自在に取り付けられて略水平面内に所定の範囲内（例えば、１８０°）で旋回自在となっている。 Hereinafter, a column hoisting device according to a best embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a state in which a transformer is lifted to the limit by a column mounting device, FIG. 2 (a) is a plan view of the column mounting device, (b) is a side view, and (c) is a front view. is there. In these drawings, reference numeral 1 is a utility pole, 2 is a pole attachment member that is detachably attached to the utility pole 1, and 3 is an arm member that extends in a substantially horizontal direction, and its base portion is rotatable to the pole attachment member 2. It is attached and can turn within a predetermined range (for example, 180 °) within a substantially horizontal plane.

４は、ガイドレールで、アーム部材３に載設されて該アーム部材３の先端側に向けて、例えば、３°傾斜するガイド面４ａを有する。５は、ガイドレール４に沿って移動自在に案内される支持部材で、この支持部材５には吊持部８が設けられ、その吊持部８には、例えば、電動チェーンブロック等の吊上手段７が吊持され、その吊上手段７によって、例えば、トランス等の機器６が吊り上げられる。一方、支持部材５とアーム部材３の先端側との間には、例えば、シメラー等の引張手段１０が介装され、機器６が吊上手段７によって吊り上げられた状態にて、その引張手段１０を操作することで機器６の位置を任意に調整できるように構成されている。   Reference numeral 4 denotes a guide rail that has a guide surface 4a that is mounted on the arm member 3 and is inclined, for example, by 3 ° toward the distal end side of the arm member 3. Reference numeral 5 denotes a support member that is movably guided along the guide rail 4. The support member 5 is provided with a suspension portion 8, and the suspension portion 8 includes a suspension such as an electric chain block. The means 7 is suspended, and the apparatus 6 such as a transformer is lifted by the lifting means 7. On the other hand, between the support member 5 and the distal end side of the arm member 3, for example, a tensioning means 10 such as a shimmer is interposed, and the tensioning means 10 is lifted by the lifting means 7. The position of the device 6 can be arbitrarily adjusted by operating the.

そのガイドレール４は傾斜したガイド面４ａを有するので、吊上手段７によって機器６を吊り上げた状態下でも、作業員が引張手段１０を操作することによって支持部材５をガイドレール４の先端（アーム部材３の先端）から上り方向（アーム部材３の基部方向）に移動させることができ、また、引張手段１０を緩めることによって重力により支持部材５をガイドレール４の下り方向（アーム部材３の先端方向）に移動させることができる。また、アーム部材３を旋回させることもできる。   Since the guide rail 4 has the inclined guide surface 4a, even when the device 6 is lifted by the lifting means 7, the operator operates the pulling means 10 so that the support member 5 is moved to the tip of the guide rail 4 (arms). The support member 5 can be moved in the upward direction (base direction of the arm member 3) from the tip of the member 3 and the support member 5 is lowered by the gravity by moving the pulling means 10 (the tip of the arm member 3). Direction). Also, the arm member 3 can be turned.

従って、電柱１に設けられた図示省略のハンガー座（又は腕金に設けた座板）等の機器設置対象物（又は場所）に対して、機器６に設けたハンガー６ａ，６ａの位置を精度よく調整することができ、従来のように作業者の腕力に依存することなく、一人の作業者で能率よく機器６を設置することができる。また、機器６を吊り上げる過程で、ＰＣアームや架線等の障害物があれば、適宜、機器６の位置を調整して障害物を避けてることができるため、従来のようにトラ綱等を使用しなくてもよく、多大の労力と時間を省くことができ、作業の安全性も向上する。なお、図示は省略するが、ハンガー座には、機器６のハンガー６ａ，６ａを掛止させるためのボルト等の掛止部材が設けられており、その掛止部材に対して機器６のハンガー６ａ，６ａを上方から落とし込むようにして掛止させて機器６を設置する。   Therefore, the position of the hangers 6a, 6a provided on the device 6 is accurately determined with respect to the device installation target (or place) such as a hanger seat (not shown) provided on the utility pole 1 (or a seat plate provided on the armrest). The device 6 can be adjusted well, and the device 6 can be efficiently installed by one worker without depending on the arm strength of the worker as in the prior art. In addition, if there is an obstacle such as a PC arm or overhead line in the process of lifting the device 6, the position of the device 6 can be adjusted as appropriate to avoid the obstacle, so the tiger rope is used as before. There is no need to do so, and a great deal of labor and time can be saved, and the safety of work is also improved. In addition, although illustration is abbreviate | omitted, the hanger seat is provided with latching members, such as a volt | bolt for latching the hangers 6a and 6a of the apparatus 6, and the hanger 6a of the apparatus 6 with respect to the latching member. , 6a is dropped from above, and the device 6 is installed.

柱装吊上装置の構成についてさらに詳しく説明すると、図２（ａ）〜（ｃ）に示すように、柱取付部材２は、本体の両側に、電柱１を挟持する一対の板金材からなるバンド部材１１，１１を回動自在に備え、そのバンド部材１１，１１の端部にボルトとナットによって固定されたフランジブラケット１１ａ，１１ａが、ボルトとナットからなる締結部材１２によって締め付けられるように構成され、電柱１を両側から挟み付けたバンド部材１１，１１を締結部材１２で締結することによって、柱取付部材２を電柱１に対して固定状態に装着することができる。   The structure of the column mounting device will be described in more detail. As shown in FIGS. 2A to 2C, the column attachment member 2 is a band made of a pair of sheet metal members that sandwich the utility pole 1 on both sides of the main body. The members 11 and 11 are rotatably provided, and flange brackets 11a and 11a fixed to the end portions of the band members 11 and 11 by bolts and nuts are fastened by fastening members 12 made of the bolts and nuts. The pole mounting member 2 can be fixedly attached to the utility pole 1 by fastening the band members 11 and 11 sandwiching the utility pole 1 from both sides with the fastening member 12.

このような構成により、電柱１を挟んでアーム部材３の反対側で締結部材１２を作業性よく締結することができる。一方、柱取付部材２の本体の前面には支持ブラケット１１ｂが取り付けられ、その支持ブラケット１１ｂには、アーム部材３の基部に上下方向に貫挿される支持ボルト１１ｃが軸支され、アーム部材３が、例えば、１８０°の範囲内に旋回自在となっている。また、その支持ブラケット１１ｂの下部には間接活線作業用の吊環（本発明の被把持部）１１ｄが付設され、間接活線操作棒の先端で吊環１１ｄを掴んで柱装吊上装置を把持できるようにしている。   With such a configuration, the fastening member 12 can be fastened with good workability on the opposite side of the arm member 3 with the utility pole 1 in between. On the other hand, a support bracket 11b is attached to the front surface of the main body of the column attachment member 2, and a support bolt 11c that is vertically inserted into the base of the arm member 3 is pivotally supported on the support bracket 11b. For example, it can turn within a range of 180 °. In addition, a suspension ring 11d for indirect live work (attached portion of the present invention) is attached to the lower part of the support bracket 11b, and the suspension ring 11d is gripped by the tip of the indirect live wire operation rod to grasp the column-mounted lifting device. I can do it.

アーム部材３は、図３（ａ）〜（ｃ）に示すように、断面口状に折曲された板金材等からなり高剛性に形成され、その本体上部にガイドレール４が一体化され、その基部には、支持ボルト１１ｃを貫挿させるための軸孔３ａが形成され、その近傍には、引張手段１０の一端側に接続された索部材１３（図１参照）の端部を掛止させるための吊環１４が付設される一方、その他端側には、ガイドレール４に案内される支持部材５の脱落を防止するためのストッパー９が立設されている。   As shown in FIGS. 3 (a) to 3 (c), the arm member 3 is made of a sheet metal material or the like bent into a cross-sectional mouth shape and is formed with high rigidity, and the guide rail 4 is integrated on the upper part of the main body, A shaft hole 3a through which the support bolt 11c is inserted is formed in the base portion, and an end portion of the cord member 13 (see FIG. 1) connected to one end side of the tension means 10 is hooked in the vicinity thereof. On the other end side, there is provided a stopper 9 for preventing the supporting member 5 guided by the guide rail 4 from falling off.

支持部材５は、図４（ａ）（ｂ）に示すように、断面矩形状に折曲された板金材等により高剛性に形成され、その本体上部には、引張手段１０の他端側に接続された索部材１５（図１参照）の端部を掛止させるための吊環１６が付設され、その直下の位置で本体の両側壁５ａ，５ａに貫装される軸ボルト１７には、ガイドレール４のガイド面４ａに摺接移動自在に転動する一対の滑車１８，１８が回動自在に枢支されている。なお、１９はナットの脱落を防止するための止めピンである。   As shown in FIGS. 4 (a) and 4 (b), the support member 5 is formed with high rigidity by a sheet metal material or the like bent into a rectangular cross section. A suspension ring 16 for hooking the end of the connected rope member 15 (see FIG. 1) is attached, and the shaft bolt 17 penetrating the both side walls 5a and 5a at a position directly below the suspension ring 16 has a guide. A pair of pulleys 18 and 18 that are slidably movable on the guide surface 4a of the rail 4 are pivotally supported. Reference numeral 19 denotes a set pin for preventing the nut from falling off.

この支持部材５は、アーム部材３の先端側から嵌め込むことができる。また、アーム部材３は、支持ボルト１１ｃを介して、柱取付部材２に対して着脱自在に取り付けられている。従って、柱装吊上装置を電柱１に対して順次各構成部材を段階的に組み付けることも可能である（図１参照）。例えば、まず、柱取付部材２を電柱１に装着し、次いで、柱取付部材２に対してアーム部材３を組み付け、そのアーム部材３に支持部材５を嵌め込めば、柱装吊上装置の組み付けが完了する。そして、吊持部８に吊上手段７を吊持させ、吊環１４，１６間に引張手段１０を介装させて、吊上手段７のチェーン７ａに接続されているフック７ｂに、機器６に掛止させた索部材６ｂを引っ掛けると、吊り上げ準備が完了する。なお、アーム部材３を柱取付部材２に一体化させておいて、柱取付部材２を電柱１に組み付けてもよく、その際に、支持部材５をアーム部材３に嵌め込んでおいてもよく、後から嵌め込んでもよい。   The support member 5 can be fitted from the distal end side of the arm member 3. The arm member 3 is detachably attached to the column attachment member 2 via a support bolt 11c. Therefore, it is also possible to assemble each component member step by step with respect to the utility pole 1 (see FIG. 1). For example, first, if the pole mounting member 2 is mounted on the utility pole 1, then the arm member 3 is assembled to the pole mounting member 2, and the support member 5 is fitted into the arm member 3, the column mounting lifting apparatus is assembled. Is completed. Then, the lifting means 7 is suspended by the suspension portion 8, the tension means 10 is interposed between the suspension rings 14, 16, and the hook 6 b connected to the chain 7 a of the lifting means 7 is connected to the device 6. When the hooked rope member 6b is hooked, preparation for lifting is completed.
