Description
【０００１】[0001]
この考案は，電柱に取り付ける配電機器その他の被吊り上げ物をクレーン等の 吊り上げ機で吊り上げる場合に，吊り上げ機側の吊り部と被吊り上げ物とを係合 させるための係合装置に関する。 The present invention relates to an engaging device for engaging a hanging portion on the hoisting machine side with an object to be lifted when a power distribution device or other object to be hoisted attached to a utility pole is hoisted by a hoist such as a crane.
【０００２】[0002]
近年，例えば変圧器や区分開閉器等の配電機器を電柱に取り付ける配電線路の 構築作業において，省力化を図るためにマニピュレータを用いることが行われて いるが，このような作業の際，従来，クレーンのフックにワイヤロープをかけ， このワイヤロープを配電機器に係合させて配電機器を吊り上げていた。すなわち ，例えば図９に示すように，クレーンのフック１にかけたワイヤロープ２を配電 機器（図示例は変圧器）３に溶接固定したフック４にかける等して，クレーンの 吊り部（フック１など）と配電機器３とを係合させていた。 In recent years, manipulators have been used to save labor in the construction work of distribution lines that attach distribution equipment such as transformers and partition switches to utility poles. A wire rope was hung on the hook of the crane, and the wire rope was engaged with the power distribution equipment to lift the power distribution equipment. That is, for example, as shown in FIG. 9, a wire rope 2 hung on a hook 1 of a crane is hung on a hook 4 welded and fixed to a power distribution device (a transformer in the example shown in the figure) to hang the hanging part (hook 1, etc.) of the crane. ) And the power distribution device 3 were engaged with each other.
【０００３】[0003]
上記のようにワイヤロープ２を用いる従来の吊り上げ方式では，ワイヤロープ ２を配電機器３に係合させる作業を手作業で行う場合には特に問題はないが，こ れをマニピュレータで行う場合には，種々の困難がある。すなわち，ワイヤロー プ２は剛体でなく自在に撓むので，マニピュレータによりワイヤロープ２をフッ ク４に掛け外しする作業は困難である。また，クレーンのフック１にはワイヤロ ープ２を掛ける上で方向性がありかつフック１自体が自在に回転するため，この 点でもマニピュレータによる作業は困難である。さらに，クレーンのフック１の 落下防止用ロック１ａの操作をマニピュレータで行うことも困難である。また， 配電機器とワイヤロープとの他の係合方法として，配電機器側にアイボルトをね じ込み，クレーンのフックに掛けたワイヤロープを前記アイボルトのリング部に 通す方法もあるが，この場合におけるマニピュレータ使用の困難性も上記とほぼ 同様である。 In the conventional hoisting method using the wire rope 2 as described above, there is no particular problem when the work of engaging the wire rope 2 with the power distribution device 3 is manually performed, but when this is performed by the manipulator. , There are various difficulties. That is, since the wire rope 2 is not a rigid body but freely bends, it is difficult to hang the wire rope 2 on and off the hook 4 by the manipulator. In addition, since the hook 1 of the crane has directionality for hanging the wire rope 2 and the hook 1 itself can freely rotate, work with the manipulator is also difficult in this respect. Further, it is difficult to operate the fall prevention lock 1a of the hook 1 of the crane with a manipulator. Another method of engaging the power distribution equipment with the wire rope is to screw the eyebolt on the power distribution equipment side and pass the wire rope hooked on the crane hook through the ring part of the eyebolt. The difficulty of using the manipulator is almost the same as above.
【０００４】 本考案は上記従来の欠点を解消するためになされたもので，ワイヤロープを用 いることなく剛体の部材のみで被吊り上げ物と係合させることができ，また被吊 り上げ物と係合させる上で方向性がなく，さらに被吊り上げ物との係合のロック 操作を容易にかつ確実に行うことができ，これにより被吊り上げ物との係合作業 を例えばマニピュレータで行える程度に容易に行うことができる吊り上げ機用の 係合装置を提供することを目的とする。The present invention has been made in order to solve the above-mentioned conventional drawbacks, and it is possible to engage with an object to be hoisted only by a rigid member without using a wire rope. There is no directionality when engaging, and furthermore, the locking operation of the engagement with the object to be hung up can be performed easily and reliably, which makes it easy to engage with the object to be hung up, for example, with a manipulator. It is an object of the present invention to provide an engaging device for a hoisting machine that can be used for the above.
【０００５】[0005]
上記課題を解決する本考案の吊り上げ機用の係合装置は，下端部に円形の係合 プレートを有する吊りロッドとこの吊りロッドの外周に摺動可能に被せられた円 筒部材とを持つ吊り金具と，内部に前記係合プレートを収容可能な係合用空間を 有するとともに側部に開口を有する逆カップ状をなし，被吊り上げ物側に固定さ れる固定金具とからなり， 前記固定金具の側部の開口は，前記係合プレートの外径ｄ3 よりも大きな幅Ｄ 3 （ｄ3 〈Ｄ3 ）を持つプレート挿通用下方開口部と，前記吊りロッドの外径ｄ 1 よりも大きく前記円筒部材の外径ｄ2 よりも小さな幅Ｄ1 （ｄ1 〈Ｄ1 〈ｄ2 ）を持つロッド挿通用上方開口部とからなり，かつ固定金具の上面部に前記円筒 部材の外径ｄ2 よりも大きく前記係合プレートの外径ｄ3 よりも小さな内径Ｄ2 （ｄ2 〈Ｄ2 〈ｄ3 ）を有する円筒部材挿通穴が設けられていることを特徴とす る。 An engaging device for a hoisting machine of the present invention which solves the above-mentioned problem is a suspending device having a suspending rod having a circular engaging plate at its lower end and a cylindrical member slidably fitted on the outer periphery of the suspending rod. It is composed of a metal fitting and a fixing metal fitting having an engaging space capable of accommodating the engaging plate therein and having an opening at a side portion and fixed to the side of the object to be lifted. The opening of the part has an outer diameter d3 Width D greater than 3 (D3 <D3 ) Has a lower opening for inserting the plate, and the outer diameter d of the suspension rod. 1 Larger than the outer diameter d of the cylindrical member2 Width less than D1 (D1 <D1 <D2 ), And the outer diameter d of the cylindrical member on the upper surface of the fixing bracket.2 Larger than the outer diameter d of the engagement plate3 Smaller inner diameter D2 (D2 <D2 <D3 ) Is provided with a cylindrical member insertion hole.
【０００６】 請求項２は，請求項１の係合装置において，吊りロッドの外周に遊嵌されたば ねにより前記円筒部材が常に下方向に付勢されていることを特徴とする。According to a second aspect of the present invention, in the engagement device according to the first aspect, the cylindrical member is always urged downward by a rod loosely fitted to the outer periphery of the suspension rod.
【０００７】[0007]
上記構成において，吊り金具の円筒部材を吊りロッドの上方に上げた状態で， 吊りロッドの下方部分およびその下端の係合プレートを固定金具の側部のロッド 挿通用上方開口部およびプレート挿通用下方開口部からそれぞれ内部の係合用空 間に挿入する。次いで，円筒部材を吊りロッドに沿って下降させる。この時，円 筒部材は固定金具の上面部の円筒部材挿通穴から係合用空間内に挿入され係合プ レート上に乗るが，円筒部材の外径ｄ2 はロッド挿通用開口部の幅Ｄ1 よりも大 きいので，円筒部材は固定金具の開口から横向きに抜けることはない。つまり， 吊りロッドは円筒部材により抜け止めされる。クレーン等の吊り上げ機で吊りロ ッドを吊り上げると，固定金具の上面部の円筒部材挿通穴の径Ｄ2 は係合プレー トの外径ｄ3 よりも小さいので，係合プレートが固定金具の上面部に係合し，固 定金具およびこれと一体の被吊り上げ物が吊り上げられる。In the above-mentioned configuration, with the cylindrical member of the suspension metal fitting raised above the suspension rod, the lower part of the suspension rod and the engagement plate at the lower end of the suspension metal fitting are connected to the side of the fixing metal fitting, the upper opening for rod insertion, and the lower portion for plate insertion. Insert each from the opening into the internal engagement space. Then, the cylindrical member is lowered along the suspension rod. At this time, the cylindrical member is inserted into the engaging space from the cylindrical member insertion hole on the upper surface of the fixing bracket and rides on the engaging plate, but the outer diameter d 2 of the cylindrical member is the width D of the rod inserting opening. Since it is larger than 1 , the cylindrical member does not come out sideways from the opening of the fixing bracket. That is, the suspension rod is prevented from coming off by the cylindrical member. When the hoisting rod is hoisted by a hoist such as a crane, the diameter D 2 of the cylindrical member insertion hole on the upper surface of the fixing bracket is smaller than the outer diameter d 3 of the engaging plate. It engages with the upper surface and the fixed metal fitting and the object to be hung are integrated.
【０００８】 請求項２においては，円筒部材を吊りロッドの上方に上げる際，円筒部材はば ねの反力に抗して持ち上げる。吊りロッドの下方部およびその下端の係合プレー トを固定金具の内部の係合用空間に挿入した後，保持した円筒部材を離すと，円 筒部材はばねの下向きの反力で下降し，固定金具の上面部の円筒部材挿通穴から 係合用空間内に挿入され，抜け止め作用を果たす。被吊り上げ物を吊り上げてい る状態では，円筒部材はばねで下向きに付勢されているので，衝撃その他の何ら かの原因で円筒部材が上に移動してしまうおそれがなく，抜け止め作用が一層確 実になる。In the second aspect, when the cylindrical member is raised above the suspension rod, the cylindrical member is lifted against the reaction force of the spring. After inserting the lower part of the hanging rod and the engaging plate of its lower end into the engaging space inside the fixing bracket, when the held cylindrical member is released, the cylindrical member is lowered by the downward reaction force of the spring and fixed. It is inserted into the engaging space through the cylindrical member insertion hole on the top surface of the metal fitting, and acts as a retainer. When the object to be lifted is being lifted, the cylindrical member is urged downward by the spring, so there is no risk of the cylindrical member moving upward due to impact or some other reason, and the retaining function is further enhanced. Be certain.

The engaging device 11 includes a hanging metal fitting 14 connected to a wire rope 13 hung on a hook (not shown) of a crane, which is a hoisting machine, and a fixing metal fitting 15 fixed to the object to be lifted 12 with a bolt.
【００１０】 前記吊り金具１４は，図３に示すように，下端部に外径ｄ3 の円形の係合プレ ート１６を有する外径ｄ1 の吊りロッド１７と，この吊りロッド１７の外周に摺 動可能に被せられた外径ｄ2 の円筒部材１８とからなっている。吊りロッド１７ の上端には，クレーンの図示略のフックに掛けたワイヤロープ１３に連結ピン１ ９を介して連結される連結部２０を一体に固定している。As shown in FIG. 3, the hanging metal fitting 14 has a hanging rod 17 having an outer diameter d 1 and a circular engaging plate 16 having an outer diameter d 3 at the lower end, and an outer circumference of the hanging rod 17. And a cylindrical member 18 having an outer diameter d 2 which is slidably covered with the cylindrical member 18. On the upper end of the hanging rod 17, a connecting portion 20 connected to a wire rope 13 hung on a hook (not shown) of the crane via a connecting pin 19 is integrally fixed.
【００１１】 前記固定金具１５は，図２にも示すように，内部に前記係合プレート１６を収 容可能な係合用空間２５を有し側部に開口２６を有する逆カップ状をなし，下端 の外周に被吊り上げ物１２にボルトで固定するためのねじ挿通穴２７ａをあけた フランジ部２７を備えている。前記開口２６は，係合プレート１６の外径ｄ3 よ りも大きな幅Ｄ3 （ｄ3 〈Ｄ3 ）有するプレート挿通用下方開口部２６ａと，吊 りロッド１７の外径ｄ1 よりも大きく円筒部材１８の外径ｄ2 よりも小さな幅Ｄ 1 （ｄ1 〈Ｄ1 〈ｄ2 ）を有するロッド挿通用上方開口部２６ｂとからなる。ま た，固定金具１５の上面部２８には円筒部材１８の外径ｄ2 よりも大きく係合プ レート１６の外径ｄ3 よりも小さな内径Ｄ2 （ｄ2 〈Ｄ2 〈ｄ3 ）を有する円筒 部材挿通穴２８ａが設けられている。上述の各部の寸法の大小関係は，次のよう に表すことができる。 ｄ1 〈Ｄ1 〈ｄ2 〈Ｄ2 〈ｄ3 〈Ｄ3 As shown in FIG. 2, the fixing member 15 has a reverse cup shape having an engaging space 25 capable of accommodating the engaging plate 16 therein and an opening 26 at a side thereof, and has a lower end. A flange portion 27 having a screw insertion hole 27a for fixing to the object to be lifted 12 with a bolt is provided on the outer periphery of the. The opening 26 has an outer diameter d of the engaging plate 16.3 Wider width D3 (D3 <D3 ) The lower opening 26a for inserting the plate and the outer diameter d of the suspension rod 171 Larger than the outer diameter d of the cylindrical member 182 Width less than D 1 (D1 <D1 <D2 ) And an upper opening 26b for rod insertion. Moreover, the outer diameter d of the cylindrical member 18 is provided on the upper surface 28 of the fixing member 15.2 Larger than the outer diameter d of the engaging plate 163 Smaller inner diameter D2 (D2 <D2 <D3 A cylindrical member insertion hole 28a having The size relationship of the above-mentioned parts can be expressed as follows. d1 <D1 <D2 <D2 <D3 <D3
【００１２】 次に，上記の係合装置１１により被吊り上げ物１２を吊り上げる際に，吊り金 具１４と固定金具１５とを係合させる係合操作について説明する。まず，図４に 示すように，吊り金具１４の円筒部材１８を吊りロッド１７の上方に上げた状態 で，吊りロッド１７の下方部分およびその下端の係合プレート１６を固定金具１ ５の側部のロッド挿通用上方開口部２６ｂおよびプレート挿通用下方開口部２６ ａからそれぞれ内部の係合用空間２５に横向きに挿入する。次いで，図５に示す ように，吊りロッド１７を持ち上げると，固定金具１５の上面部２８の円筒部材 挿通穴２８ａの径Ｄ2 は係合プレート１６の外径ｄ3 よりも小さいので，係合プ レート１６が固定金具１５の上面部２８に係合する。次いで図６に示すように， 円筒部材１８を吊りロッド１７に沿って下降させると，円筒部材１８の外径ｄ2 はロッド挿通用開口部２６ｂの幅Ｄ1 よりも大きいので，円筒部材１８は固定金 具１５の開口２６から横向きに抜けることはない。つまり，吊りロッド１７は円 筒部材１８により抜け止めされ，吊り金具１４と固定金具１５とのロックが行わ れる。次いで，クレーンのワイヤロープ１３で吊りロッド１７を吊り上げると， 吊り金具１４を介して固定金具１５およびこれと一体の被吊り上げ物１２が吊り 上げられる。なお，円筒部材１８を下降させてロックするタイミングは，上記と は別に，係合プレート１６が図４に示すように下方にある段階で行うこともでき る。Next, an engaging operation for engaging the hanging metal fitting 14 and the fixing metal fitting 15 when the object 12 to be lifted is hoisted by the engaging device 11 will be described. First, as shown in FIG. 4, with the cylindrical member 18 of the hanging fitting 14 raised above the hanging rod 17, the lower portion of the hanging rod 17 and the engaging plate 16 at the lower end thereof are attached to the side portions of the fixing fitting 15. From the rod insertion upper opening 26b and the plate insertion lower opening 26a into the engaging space 25 inside. Next, as shown in FIG. 5, when the suspension rod 17 is lifted, the diameter D 2 of the cylindrical member insertion hole 28a of the upper surface 28 of the fixing member 15 is smaller than the outer diameter d 3 of the engaging plate 16, so The plate 16 engages with the upper surface portion 28 of the fixing member 15. Next, as shown in FIG. 6, when the cylindrical member 18 is lowered along the suspension rod 17, the outer diameter d 2 of the cylindrical member 18 is larger than the width D 1 of the rod insertion opening 26b. It does not come out sideways from the opening 26 of the fixing tool 15. That is, the suspension rod 17 is prevented from coming off by the cylindrical member 18, and the suspension fitting 14 and the fixing fitting 15 are locked. Then, when the hanging rod 17 is lifted by the wire rope 13 of the crane, the fixing metal fitting 15 and the object to be hung 12 integrated with the fixing metal fitting 15 are lifted via the hanging metal fitting 14. The timing of lowering and locking the cylindrical member 18 can be performed at a stage where the engaging plate 16 is at the lower side as shown in FIG. 4, separately from the above.
【００１３】 上記の係合装置１１によれば，被吊り上げ物１２にワイヤロープをかけるもの でなく，吊り金具１４および固定金具１５はすべて剛体の部材からなるので，マ ニピュレータで操作することは容易である。なお，クレーンのフックに掛けるワ イヤロープ１３は，単に吊り金具１４を垂直に吊り下げるだけであるから，マニ ピュレータの操作性に支障とならない。また，吊り金具１４自体にはこれを固定 金具１５に係合させる上で方向性がないので，この点でも係合操作をマニピュレ ータにより行うことは容易である。なお，吊り金具１４の固定金具１５に対する 方向性（開口２６の方向性）は，マニピュレータを操作する上で特に支障とはな らない。According to the above-described engaging device 11, since the wire rope is not hung on the object to be lifted 12 and the hanging metal fitting 14 and the fixing metal fitting 15 are all made of rigid members, it is easy to operate with the manipulator. Is. The wire rope 13 to be hung on the hook of the crane does not hinder the operability of the manipulator because the hanging metal fitting 14 is simply hung vertically. Further, since the hanging metal fitting 14 itself has no directivity in engaging this with the fixing metal fitting 15, also in this respect, it is easy to perform the engaging operation by the manipulator. The direction of the hanging metal fitting 14 with respect to the fixing metal fitting 15 (direction of the opening 26) does not particularly hinder the operation of the manipulator.
【００１４】 図７，図８に他の実施例を示す。この実施例は，前記吊りロッド１７の外周に 円筒部材１８を常に下方向に付勢させるばね３０を遊嵌させたものである。7 and 8 show another embodiment. In this embodiment, a spring 30 for constantly urging the cylindrical member 18 downward is loosely fitted around the suspension rod 17.
【００１５】 上記のようにばね３０を有する係合装置では，円筒部材１８を吊りロッド１７ の上方に上げる際，図７に示すように円筒部材１８はばね３０の反力に抗して持 ち上げる。吊りロッド１７の下方部分および係合プレート１６を固定金具１５の 内部に挿入した後，保持した円筒部材１８を離すと，図８に示すように円筒部材 １８はばね３０の下向きの反力で下降し，固定金具１５の上面部２８の円筒部材 挿通穴２８ａから係合用空間内に挿入され，抜け止め作用を果たす。この状態で 被吊り上げ物１２を吊り上げるが，この状態では，円筒部材１８は常時ばね３０ で下向きに付勢されているので，衝撃その他の何らかの原因で円筒部材１８が上 に移動してしまうおそれがなく，抜け止め作用がより一層確実になる。In the engagement device having the spring 30 as described above, when the cylindrical member 18 is raised above the suspension rod 17, the cylindrical member 18 holds against the reaction force of the spring 30 as shown in FIG. increase. After the lower portion of the hanging rod 17 and the engaging plate 16 are inserted into the fixing bracket 15, the held cylindrical member 18 is released, and the cylindrical member 18 is lowered by the downward reaction force of the spring 30 as shown in FIG. Then, it is inserted into the engagement space from the cylindrical member insertion hole 28a of the upper surface portion 28 of the fixing member 15 and fulfills the retaining function. The object to be lifted 12 is hoisted in this state, but in this state, since the cylindrical member 18 is constantly urged downward by the spring 30, there is a possibility that the cylindrical member 18 may move upward due to an impact or some other reason. Without, the retaining action becomes more reliable.
【００１６】 なお，本考案の係合装置は，マニピュレータに限らずロボットで作業を行う場 合にも適用でき，また，係合作業を手作業で行う場合にも適用することができ， さらには，クレーン以外の吊り上げ機で吊り上げる場合にも適用することができ る。また，本考案の係合装置で吊り上げる被吊り上げ物は，配電機器に限らず任 意である。The engagement device of the present invention can be applied not only to the manipulator but also to the case of performing work by a robot, and also to the case of performing the engagement work manually. It can also be applied when hoisting with a hoist other than a crane. The object to be hoisted by the engagement device of the present invention is not limited to the power distribution equipment, but is arbitrary.
【００１７】[0017]
本考案によれば，吊り金具と固定金具との係合，すなわち吊り金具と被吊り上 げ物との係合は，ワイヤロープを用いることなくすべて剛体の部材のみで行うも のであるから，この係合操作を容易にマニピュレータで行うことができる。 According to the present invention, the engagement between the hanging metal fittings and the fixing metal fittings, that is, the engagement between the hanging metal fittings and the object to be hung is performed only by the rigid member without using the wire rope. The engaging operation can be easily performed by the manipulator.
【００１８】 また，吊り上げ機に連結される吊り金具側には，被吊り上げ物に係合（直接に は固定金具に係合）させる上で方向性がないので，この点でも係合操作をマニピ ュレータにより行うことは容易である。Further, since there is no direction in engaging the object to be hung up (directly engaging the fixing metal fitting) on the side of the hanging metal fitting connected to the lifting machine, the manipulating operation is also required in this respect. It is easy to do with a simulator.
【００１９】 さらに，吊り金具と被吊り上げ物との係合のロックおよびロック解除操作は， 円筒部材を自重で下降させあるいは単に上にスライドさせるという単純なもので あり，このロック操作もマニピュレータで容易に行うことができる。また，自重 で下降した状態でロック状態を維持するので，安定確実なロックが行われる。Furthermore, the locking and unlocking operation of the engagement between the hanging metal fitting and the object to be lifted is a simple one in which the cylindrical member is lowered by its own weight or simply slid up, and this locking operation is also easy with the manipulator. Can be done. In addition, the locked state is maintained even when the robot is lowered by its own weight, so stable and reliable locking is performed.
【００２０】 請求項２によれば，被吊り上げ物を吊り上げた状態では，抜け止め作用を持つ 円筒部材が常時ばねで下向きに付勢されているので，衝撃その他の何らかの原因 で円筒部材が上に移動してしまうおそれもなく，抜け止め作用がより一層確実に なる。According to the second aspect, since the cylindrical member having the retaining function is always urged downward by the spring when the object to be lifted is lifted, the cylindrical member is moved upward due to an impact or some other cause. There is no risk of movement, and the retaining function becomes even more reliable.
