本発明について実施例を挙げて詳細に説明する。 The present invention will be described in detail with reference to examples.

図１〜図３を参照して実施例１の穴吊り治具１０について説明する。この穴吊り治具１０は、一対の脚部１２ａ，１２ｂの間に下向きに開口するワーク挿入口１３を備えた本体１１と、本体１１の一対の脚部１２ａ，１２ｂ間に係脱自在に架け渡される吊ピン１４を有する。ワーク挿入口１３は、この穴吊り治具１０で吊り上げようとする鋼材などのワークＷの厚さより大きな開口幅を有するものとして形成され、したがって該ワークＷの端部を挿入可能とされている（図８参照）。また、ワーク挿入口１３の深さ（言い換えれば脚部１２ａ，１２ｂの長さ）は該ワークＷの端部に厚さ方向に貫通して形成されている穴に吊ピン１４が挿入・通過できる深さとされている。 With reference to FIGS. 1-3, the hole suspension jig | tool 10 of Example 1 is demonstrated. The hole-hanging jig 10 is detachably mounted between a main body 11 having a workpiece insertion opening 13 that opens downward between a pair of leg portions 12a and 12b, and a pair of leg portions 12a and 12b of the main body 11. Has a hanging pin 14 to be passed. The workpiece insertion port 13 is formed to have an opening width larger than the thickness of the workpiece W such as a steel material to be lifted by the hole suspension jig 10, and therefore the end portion of the workpiece W can be inserted ( (See FIG. 8). The depth of the workpiece insertion port 13 (in other words, the length of the leg portions 12a and 12b) is such that the suspension pin 14 can be inserted into and passed through a hole formed through the end portion of the workpiece W in the thickness direction. It is said to be deep.

吊ピン１４の軸１５は、本体１１の脚部１２ａ，１２ｂの下端近くに形成されたピン挿通穴１６ａ，１６ｂを挿通して脚部１２ａ，１２ｂ間に架け渡されるに十分な長さを有し、その基端にはチェーン係止穴１７を有する頭部１８が固着され、その先端にはストッパ１９がスプリングピン２０を介して吊ピン軸１５に対して回動自在に設けられている。また、吊ピン１４の頭部１８と脚部１２ａとの間において軸１５の回りにコーンスプリング２１が巻装されており、頭部１８を脚部１２ａから引き離す方向に吊ピン１４を移動付勢している。 The shaft 15 of the suspension pin 14 has a length sufficient to pass through the pin insertion holes 16a and 16b formed near the lower ends of the leg portions 12a and 12b of the main body 11 and span between the leg portions 12a and 12b. A head 18 having a chain locking hole 17 is fixed to the base end thereof, and a stopper 19 is provided at the tip thereof so as to be rotatable with respect to the suspension pin shaft 15 via a spring pin 20. Further, a cone spring 21 is wound around the shaft 15 between the head portion 18 and the leg portion 12a of the suspension pin 14, and the suspension pin 14 is urged to move in a direction to separate the head portion 18 from the leg portion 12a. doing.

吊ピン１４は後述するように本体１１の脚部１２ａ，１２ｂに対して抜き差し可能であるが、吊チェーン２２を介して本体１１に連結されているので、抜いたときであっても不意に脱落することなく本体１１に付属する。この実施例では、吊チェーン２２は、リング２３，チェーン止め２４および六角穴付きボルト２５を介して本体１１の脚部１２ａ側の側面に連結されており、その先端がリング２６を介して吊ピン頭部１８のチェーン係止穴１７に係止されている。 As will be described later, the hanging pin 14 can be inserted into and removed from the leg portions 12a and 12b of the main body 11, but since it is connected to the main body 11 via the hanging chain 22, it will drop off unexpectedly even when it is pulled out. It is attached to the main body 11 without doing. In this embodiment, the suspension chain 22 is connected to the side surface of the main body 11 on the leg 12a side via a ring 23, a chain stopper 24, and a hexagon socket head bolt 25, and the tip of the suspension chain 22 is connected to the suspension pin via the ring 26. It is locked in the chain locking hole 17 of the head 18.

図１〜図３は吊ピン１４が本体脚部１２ａ，１２ｂのピン挿通穴１６ａ，１６ｂを通って装着されている状態を示している。この状態において、吊ピン１４先端のストッパ１９は吊ピン軸１５に対して下向きに折り曲げられており、コーンスプリング２１の付勢力を受けてその側面が脚部１２ｂの外側面に接している。これにより吊ピン１４の装着状態が維持され、吊り上げ作業時にはこの状態で使用される。 1 to 3 show a state in which the suspension pin 14 is mounted through the pin insertion holes 16a and 16b of the main body legs 12a and 12b. In this state, the stopper 19 at the tip of the suspension pin 14 is bent downward with respect to the suspension pin shaft 15 and receives the urging force of the cone spring 21 so that its side surface is in contact with the outer surface of the leg portion 12b. Thereby, the mounting state of the hanging pin 14 is maintained, and it is used in this state during the lifting work.

この装着状態から吊ピン１４を引き抜くには、コーンスプリング２１の付勢力に抗して頭部１８を矢印Ａ方向に押し込み、これによって脚部１２ｂの外側面から離れたストッパ１９を矢印Ｂ方向に回転させて吊ピン軸１５と平行にして引き抜けば良い（図４）。このようにして引き抜かれた吊ピン１４は本体１１の脚部１２ａ，１２ｂから離脱するが、前述のように吊チェーン２２などを介して本体１１に連結されているので、落下することなく本体１１に付属する（図５）。 In order to pull out the suspension pin 14 from this mounted state, the head 18 is pushed in the direction of arrow A against the urging force of the cone spring 21, and thereby the stopper 19 separated from the outer surface of the leg 12b is moved in the direction of arrow B. It is only necessary to rotate and pull it out parallel to the suspension pin shaft 15 (FIG. 4). The pulling pin 14 pulled out in this way is detached from the legs 12a and 12b of the main body 11, but is connected to the main body 11 via the hanging chain 22 and the like as described above. (Fig. 5).

説明するまでもないことであろうが、この状態から吊ピン１４を本体脚部１２ａ，１２ｂのピン挿通穴１６ａ，１６ｂに順次通過させていき、コーンスプリング２１の付勢力に抗して頭部１８を最奥まで押し込んだ状態で先端のストッパ１９を吊ピン軸１５に対して下向きに折り曲げた状態にした後に頭部１８から手を離せば、図１〜図３に示すような装着状態が得られる。なお、図４および図５では後述の吊環２７を図示省略している。 Needless to say, the suspension pin 14 is sequentially passed through the pin insertion holes 16a and 16b of the body legs 12a and 12b from this state, and the head is resisted against the urging force of the cone spring 21. If the hand is released from the head 18 after the stopper 19 at the tip is bent downward with respect to the suspension pin shaft 15 with the end 18 pushed in, the mounting state as shown in FIGS. can get. 4 and 5, a suspension ring 27 described later is omitted.

本体１１の上方には吊環２７が左右回転自在且つ全周回転自在に連結されている。以下、この吊環連結構造について、図１〜図３と共に図６，図７を併せて参照して詳述する。 A suspension ring 27 is connected to the upper side of the main body 11 so as to be able to rotate left and right and rotate around the entire circumference. Hereinafter, this suspended ring connecting structure will be described in detail with reference to FIGS. 6 and 7 together with FIGS.

本体１１には上面開口の雌ネジ部２８が形成され、この雌ネジ部２８にロッド装着部材２９の雄ネジ３０を螺合させることによってロッド装着部材２９が本体１１に固定されている。図７に示されるように、ロッド装着部材２９は略円柱形状に形成され、その上面には溝３１，３１が対向する２箇所に径方向に整列して延長するように形成されていて、これら溝３１，３１に適当な治具（図示せず）を当ててロッド装着部材２９を本体１１の雌ネジ部２８に螺着固定する。符号３２は、このようにして本体１１に固定されたロッド装着部材２９を抜け止めするための六角穴付止めネジである。ロッド装着部材２９の内径空間３３は下端部において徐々に拡径するテーパー面３４を有している。 A female screw portion 28 having an upper surface opening is formed in the main body 11, and the rod mounting member 29 is fixed to the main body 11 by screwing a male screw 30 of the rod mounting member 29 into the female screw portion 28. As shown in FIG. 7, the rod mounting member 29 is formed in a substantially cylindrical shape, and grooves 31, 31 are formed on the upper surface thereof so as to extend in a radially aligned manner at two opposing positions. An appropriate jig (not shown) is applied to the grooves 31, 31 to fix the rod mounting member 29 to the female screw portion 28 of the main body 11. Reference numeral 32 denotes a hexagon socket set screw for preventing the rod mounting member 29 fixed to the main body 11 from coming off. The inner diameter space 33 of the rod mounting member 29 has a tapered surface 34 that gradually increases in diameter at the lower end.

本体１１の雌ネジ部２８に螺着固定されたロッド装着部材２９に対して、回転ロッド３５が全周回転自在に装着されている。図６に示されるように、回転ロッド３５は、ロッド装着部材２９の内径空間３３と略同径または若干小径である円柱形状の主部３６と、主部３６の下端においてテーパー面３７を介して徐々に拡径されている基部３８と、主部３６の上方に連続する上端板状部４０とを有する。回転ロッド３５は、ロッド装着部材２９の内径空間３３に下から挿入することにより、主部３６が内径空間３３に収容されると共にテーパー面３４，３７同士が接することとなって、ロッド装着部材２９に組み付けられる。ロッド装着部材２９は、上記のように回転ロッド３５を組み付けた状態で、本体１１の雌ネジ部２８に螺着固定されているので、テーパー面３４，３７同士が摺接面となって、回転ロッド３５はロッド装着部材２９に対して（したがって本体１１に対して）全周回転自在である。 A rotating rod 35 is mounted on a rod mounting member 29 that is screwed and fixed to the female screw portion 28 of the main body 11 so as to be rotatable around the entire circumference. As shown in FIG. 6, the rotating rod 35 includes a cylindrical main portion 36 that is substantially the same diameter or slightly smaller in diameter than the inner diameter space 33 of the rod mounting member 29, and a tapered surface 37 at the lower end of the main portion 36. It has a base 38 that is gradually expanded in diameter and an upper end plate-like portion 40 that continues above the main portion 36. The rotating rod 35 is inserted into the inner diameter space 33 of the rod mounting member 29 from below, so that the main portion 36 is accommodated in the inner diameter space 33 and the tapered surfaces 34 and 37 are in contact with each other. Assembled into. Since the rod mounting member 29 is screwed and fixed to the female screw portion 28 of the main body 11 with the rotating rod 35 assembled as described above, the taper surfaces 34 and 37 are slidably contacting each other. The rod 35 is rotatable around the entire circumference with respect to the rod mounting member 29 (and therefore with respect to the main body 11).

本体１１の雌ネジ部２８に螺着固定されたロッド装着部材２９に対して回転ロッド３５が上記のように全周回転自在に装着された状態において、回転ロッド３５の上端板状部４０は本体１１の上方に突出しており（図１〜図３参照）、その軸穴３９および吊環２７の下端二股部における軸穴（符号なし）に吊環ボルト４１を通して先端にナット４２およびスプリングピン４３を設けることによって、吊環２７が左右回転自在に連結される。 In the state where the rotating rod 35 is rotatably mounted on the rod mounting member 29 screwed and fixed to the female thread portion 28 of the main body 11 as described above, the upper end plate-shaped portion 40 of the rotating rod 35 is the main body. 11 (see FIGS. 1 to 3), and a nut 42 and a spring pin 43 are provided at the tip of the shaft hole 39 and a shaft hole (not indicated) at the lower end bifurcated portion of the suspension ring 27 through a suspension ring bolt 41. Thus, the suspension ring 27 is connected so as to be rotatable in the left-right direction.

以上の構成により、吊環２７は本体１１に対して左右回転自在且つ全周回転自在である。ここで左右回転自在とは、吊環２７が吊環ボルト４１を回転軸として本体１１の上方で約１８０度の角度範囲に亘って自由に回転することを意味し、言い換えれば略水平状態（図１仮想線状態）と略垂立状態（図１実線状態）との間で自由に起伏することを意味する（図１参照）。また、全周回転自在とは、回転ロッド３５が本体１１に対してその軸芯（垂直軸）を中心として両方向３６０度自由に回転することを意味する（図２参照）。この実施形態では、本体１１と回転ロッド３５の負荷をロッド装着部材２９のテーパー面３４で受けている。 With the above configuration, the suspension ring 27 is rotatable to the left and right and to the entire periphery with respect to the main body 11. Here, “right and left freely rotatable” means that the suspension ring 27 freely rotates over the angle range of about 180 degrees above the main body 11 with the suspension ring bolt 41 as the rotation axis. It means to freely undulate between a line state) and a substantially vertical state (solid line state in FIG. 1) (see FIG. 1). Further, the ability to rotate all around the circumference means that the rotating rod 35 freely rotates 360 degrees with respect to the main body 11 around its axis (vertical axis) (see FIG. 2). In this embodiment, the load of the main body 11 and the rotating rod 35 is received by the tapered surface 34 of the rod mounting member 29.

この穴吊り治具１０を用いて鋼材などのワークＷを吊り上げるときの状態図が図８および図９に示されている。取付用や組立用の穴（図示せず）があらかじめ端部に設けられている鋼材などのワークＷを吊り上げるに際して、該端部を本体１１のワーク挿入口１３に挿入した状態において、吊ピン１４を脚部１２ａのピン挿通穴１６ａ、ワークＷの穴および脚部１２ｂのピン挿通穴１６ｂに順次に通した後にストッパ１９を折り曲げて抜け止め装着し、この状態で、クレーンからのスリング材をフック（いずれも図示せず）などを介して吊環２７に係止して、ワークＷを吊り上げる。このとき、前述のように、吊環２７は左右回転自在（図８参照）且つ全周回転自在（図９参照）に本体１１に連結されているので、シャックルやカップリングなどを用いる必要なしに、円滑に吊り作業を行うことができる。 FIGS. 8 and 9 show state diagrams when a workpiece W such as a steel material is lifted using the hole hanging jig 10. When lifting a workpiece W such as a steel material in which an attachment or assembly hole (not shown) is provided at an end in advance, the suspension pin 14 is inserted in a state where the end is inserted into the workpiece insertion port 13 of the main body 11. Are sequentially passed through the pin insertion hole 16a of the leg portion 12a, the hole of the workpiece W and the pin insertion hole 16b of the leg portion 12b, and the stopper 19 is bent and attached to prevent it from falling out. In this state, the sling material from the crane is hooked. The workpiece W is lifted by being engaged with the suspension ring 27 via (not shown) or the like. At this time, as described above, the suspension ring 27 is connected to the main body 11 so as to be rotatable left and right (see FIG. 8) and freely rotatable around the entire circumference (see FIG. 9), so there is no need to use a shackle or a coupling. The suspension work can be performed smoothly.
