Description

本考案は、例えば工場や港湾で、クレーン等で荷を吊り上げて移動させる際に使用し、積み荷がない状態で傾いている自動式吊り具に関する。 The present invention relates to an automatic lifting device that is used when a load is lifted and moved by a crane or the like in a factory or a harbor, for example, and is tilted without loading.

従来、クレーンで荷を移動する場合には、鉤状に形成された吊り具が使用される。そして、荷側吊り環に吊り具を掛ける際に、吊り具の下部が干渉する場合や微小な位置調整が困難な場合は、吊り具を人力等により直接掛ける作業を必要とする。また、吊り具取り外し時にも同様に、吊り具を、人力等で直接取り外す作業が発生することがある。
そこで、特許文献1に記載のような吊り具が提案されている。この吊り具は、鉤の上端に雄ねじを形成して、半円状に屈曲した吊り環の下部に一体的に設けられた中空円盤の中央にナットで固定できるようにし、更に、鉤の上端にはバランスウェイトを設けて構成されている。これによって、吊り具をワイヤロープ等に吊り下げると、バランスウェイト(重錘)が作用して鉤が傾き、荷側吊り環に鉤を自動的に掛けることができる構造となっていた。
Conventionally, when moving a load with a crane, a hanging tool formed in a hook shape is used. Then, when hanging the hanging tool on the load-side hanging ring, if the lower part of the hanging tool interferes or fine position adjustment is difficult, a work for directly hanging the hanging tool by human power or the like is required. Similarly, when removing the hanger, an operation of directly removing the hanger by human power may occur.
Therefore, a hanging tool as described in Patent Document 1 has been proposed. This hanger has a male thread at the top of the heel so that it can be fixed with a nut in the center of a hollow disk integrally provided at the bottom of the semicircular bent ring. Is configured with a balance weight. As a result, when the hanger is hung on a wire rope or the like, the balance weight (weight) acts to tilt the heddle so that the hanger can be automatically hung on the load-side hanger.

特開平10−81483号公報JP-A-10-81483

しかしながら、特許文献1に記載の吊り具は、部品点数が多く、構造が複雑であり、更には、ワイヤロープに対して半円状の吊り環の滑りが十分でない場合には、鉤の傾きが一定せず、場合によっては荷側の吊り環に掛止しにくいという問題があった。
また、バランスウェイトが将棋の駒状となって広い面積を有するので、斜め上部から鉤を見た場合、荷側の吊り環が隠れる場合があって、大型のクレーンなどに使用した場合、作業性が悪いという問題があった。
However, the suspension tool described in Patent Document 1 has a large number of parts, a complicated structure, and further, when the semicircular suspension ring is not sufficiently slipped with respect to the wire rope, the inclination of the hook is small. There is a problem that it is not constant and in some cases, it is difficult to hang on the hanging ring on the cargo side.
Also, since the balance weight is a shogi piece and has a large area, the load-side suspension ring may be hidden when the bag is viewed from diagonally above. There was a problem of being bad.

本考案では上記の欠点を解決し、構造が簡単で、掛け止め掛け外し作業の効率化ができる吊り具を提供しようとするものであり、その要旨は、鉤状に屈曲した吊り具本体と、該吊り具本体の頂部に一体的に連接され前記吊り具本体の屈曲方向と同一向きに屈曲したバランスウェイト部とを有し、前記吊り具本体と前記バランスウェイト部の中間には、支持ピンが回転可能に嵌入する軸孔が設けられていることにある。
なお、本考案に係る自動式吊り具において、前記支持ピンはシャックルの連結ピンであって、該シャックルを介して昇降用ワイヤロープに連結されるものであってもよい。
In the present invention, the above-mentioned drawbacks are solved, a structure is simple, and an attempt is made to provide a lifting device capable of improving the efficiency of the hanging and unloading work. A balance weight portion integrally connected to a top portion of the suspension body and bent in the same direction as a bending direction of the suspension body, and a support pin is provided between the suspension body and the balance weight portion. There exists in the shaft hole which fits rotatably.
In the automatic hanging device according to the present invention, the support pin may be a connecting pin for a shackle, and may be connected to a lifting wire rope via the shackle.

本考案に係る自動式吊り具においては、吊り具本体に掛止される荷がない場合には、吊り具本体は、頂部に接続されたバランスウェイト部の働きにより、吊り具本体(鉤状部分)の開口部が、荷側の吊り環に対して開いているような位置で静止するので、吊り具本体の吊り環への挿入が容易となり、この自動式吊り具を吊り下げた状態で移動させることによって、又は荷の方を移動させることによって、吊り環に自動式吊り具を掛止できる。
そして、自動式吊り具を巻き上げた場合には、自動式吊り具は軸孔に装着されている支持ピンを中心にして回動し、その直下に吊り具本体が位置して確実に荷に設けられた吊り環を掛止できる。
次に、荷を下ろす場合には、自動式吊り具を下げていくと、荷が接地することによって、吊り具本体の荷重がなくなり、バランスウェイト部によって吊り具本体が回転し、吊り環から自動的に外し易いようになり、この自動式吊り具を所定方向に横移動又は荷をその逆方向に移動させることによって、吊り具本体から吊り環が外れることになる。このため、吊り具の取り外し作業が容易になる。
In the automatic hanging device according to the present invention, when there is no load to be hung on the hanging device main body, the hanging device main body is suspended by the balance weight portion connected to the top portion. ) Is stationary at a position where it is open with respect to the load-side suspension ring, making it easy to insert the suspension body into the suspension ring and moving the automatic suspension in a suspended state. The automatic suspension can be hooked on the suspension ring by moving the load or moving the load.
When the automatic lifting device is rolled up, the automatic lifting device rotates around the support pin attached to the shaft hole, and the lifting device main body is positioned directly below it to ensure that it is mounted on the load. You can hang a hanging ring.
Next, when unloading the load, when the automatic lifting device is lowered, the load is grounded, so that the load on the lifting device body is eliminated, and the lifting device body is rotated by the balance weight part. It becomes easy to remove the suspension, and the suspension ring is detached from the suspension body by laterally moving the automatic suspension in a predetermined direction or moving the load in the opposite direction. For this reason, the removal work of a hanging tool becomes easy.

以上のように本考案に係る自動式吊り具は、荷の移動時に行う吊り具を掛ける作業及び掛け外す作業を容易にする。
また、その構造が簡単で部品点数の少なく、荷重がかかる部分にねじ機構等を用いていないので、信頼性の高い吊り具となる。
As described above, the automatic hanging tool according to the present invention facilitates the work for hanging and hanging the hanging tool when the load is moved.
In addition, since the structure is simple, the number of parts is small, and a screw mechanism or the like is not used in a portion to which a load is applied, the suspension is highly reliable.

続いて、添付した図面を参照し、本考案を具体化した一実施の形態に係る自動式吊り具について説明し、本考案の理解に供する。
ここに、図1は本考案の一実施の形態に係る自動式吊り具の側面図、図2(A)、(B)、(C)は同自動式吊り具の使用状態の説明図である。
Next, with reference to the attached drawings, an automatic suspension according to an embodiment embodying the present invention will be described to provide an understanding of the present invention.
Here, FIG. 1 is a side view of an automatic lifting device according to an embodiment of the present invention, and FIGS. 2A, 2B, and 2C are explanatory views of the usage state of the automatic lifting device. .

図1に示すように、本考案の一実施の形態に係る自動式吊り具10は、鉄又はステンレスの例えば鍛造物からなって、鉤状に屈曲した吊り具本体11と、吊り具本体11の頂部に一体的に連接されたバランスウェイト部12とを有している。以下、これらについて詳しく説明する。
吊り具本体11は通常のフックと同じくJ字状に屈曲しているが、先側の鉤部13の内側先部は側面視して直線状となっている。鉤部13の内側中央部は円弧状に屈曲して、掛止しようとする吊り環が円滑に嵌入し、しかも鉤部13の内側底部で止まるようになっている。
As shown in FIG. 1, an automatic lifting device 10 according to an embodiment of the present invention is composed of, for example, a forging made of iron or stainless steel, and a lifting device body 11 bent in a bowl shape, and a lifting device body 11. And a balance weight portion 12 integrally connected to the top portion. These will be described in detail below.
The lifting device main body 11 is bent in a J-shape like a normal hook, but the inner front portion of the front collar portion 13 is straight when viewed from the side. The inner central portion of the collar portion 13 is bent in an arc shape so that a hanging ring to be hooked is smoothly inserted and is stopped at the inner bottom portion of the collar portion 13.

この吊り具本体11の頂部には一体的にバランスウェイト部12が連結されているが、このバランスウェイト部12は、基側14が吊り具本体11に直線状に連結し、中間部でおり曲がった重量部位15を有している。バランスウェイト部12はこの実施の形態では直線状の部材を吊り具本体11の鉤部13の曲げ方向に約40〜50度に曲げて形成されている。吊り具本体11とバランスウェイト部12の連結部には支持ピン16が回転可能に挿通する軸孔17が設けている。そして、軸孔17にシャックル18の支持ピン16を挿通し、このシャックル18を昇降用ワイヤロープ21等で吊り下げた場合、バランスウェイト部12の重量によって、吊り具本体11が垂直に対して40〜50度(例えば、約45度)で傾くようになっている。この状態で、鉤部13の内側直線がほぼ水平になり、荷側に設けられている吊り環に容易に嵌入できるようになっている。なお、支持ピン16はこの実施の形態においてはシャックル18の連結ピンを使用したが、別に設けたピンでその両側にU字状の金具を溶接したものであってもよい。 A balance weight portion 12 is integrally connected to the top portion of the hanger body 11. The balance weight portion 12 has a base side 14 linearly connected to the hanger body 11 and is bent at an intermediate portion. And has a weight part 15. In this embodiment, the balance weight portion 12 is formed by bending a linear member at about 40 to 50 degrees in the bending direction of the flange portion 13 of the hanger body 11. A shaft hole 17 through which the support pin 16 is rotatably inserted is provided in the connecting portion between the hanger body 11 and the balance weight portion 12. Then, when the support pin 16 of the shackle 18 is inserted into the shaft hole 17 and this shackle 18 is suspended by the lifting wire rope 21 or the like, the suspension main body 11 is 40 to the vertical by the weight of the balance weight portion 12. It is inclined at ˜50 degrees (for example, about 45 degrees). In this state, the inner straight line of the flange portion 13 is substantially horizontal, and can be easily fitted into a hanging ring provided on the load side. In this embodiment, the connection pin 16 of the shackle 18 is used as the support pin 16, but a U-shaped metal fitting may be welded to both sides of the pin provided separately.

次に、図2を参照しながら、この自動式吊り具10の使用方法及びその動作について説明する。
図2(A)の状態で、荷19の上部に吊り環20が設けられている場合、昇降用ワイヤロープ21で吊り下げた自動式吊り具10を所定の高さに配置し、自動式吊り具10を横移動、又は荷19を横移動することによって、自動式吊り具10の鉤部13が吊り環20に嵌入する。
Next, with reference to FIG. 2, the usage method and the operation of the automatic lifting device 10 will be described.
In the state of FIG. 2 (A), when the suspension ring 20 is provided on the upper portion of the load 19, the automatic suspension device 10 suspended by the lifting wire rope 21 is arranged at a predetermined height, and the automatic suspension is performed. When the tool 10 is moved laterally or the load 19 is moved laterally, the flange 13 of the automatic lifting tool 10 is fitted into the hanging ring 20.

この状態で、図2(B)に示すように、昇降用ワイヤロープ21を引き上げると、自動式吊り具10によって荷19は引き上げられるが、荷19の重心Pが軸孔17の直下になるので、自動式吊り具10は、吊り具本体11が全体として垂直になるように回動する。これによって、鉤部13の先側は上り傾斜となるので、吊り環20は鉤部13から容易に外れないことになる。 In this state, as shown in FIG. 2B, when the lifting wire rope 21 is pulled up, the load 19 is pulled up by the automatic lifting device 10, but the center of gravity P of the load 19 is directly below the shaft hole 17. The automatic hanger 10 rotates so that the hanger body 11 is vertical as a whole. As a result, the front side of the flange portion 13 is inclined upward, so that the suspension ring 20 is not easily detached from the flange portion 13.

次に、昇降用ワイヤロープ21を下げて荷19を接地させた場合には、鉤部13から吊り環20が離れるので、自動式吊り具10がバランスウェイト部12の作用によって40〜50度程度傾く。この状態で、自動式吊り具10又は荷19を所定方向に移動させることによって、図2(C)に示すように、鉤部13と吊り環20の掛止状態を解くことになる。即ち、荷19が接地して荷19の荷重が解放されると、自動式吊り具10全体が傾き、水平状態に外れ易い形状になると共に、垂直状態にも外れ易い形状になり、この自動式吊り具10を自動的に外すことができる。
また、荷19の荷重が解放され、この自動式吊り具10の傾きが発生する瞬間に昇降用ワイヤロープ21と自動式吊り具10は自由開放状態になり、このときの慣性力によって自動式吊り具10は吊り環20より外れる方向に移動し、自動式吊り具10は吊り環20より外れる。昇降用ワイヤロープ21と自動式吊り具10は振れを起こし、ほとんどの場合、吊り環20内に鉤部13が入ることはなく、吊り環20より外れた状態となる。従って、吊り環20を設けた荷19の掛止及び掛止状態を解くことを自動的に行うことが可能となる。
Next, when the lifting wire rope 21 is lowered and the load 19 is grounded, the suspension ring 20 is separated from the collar portion 13, so that the automatic lifting device 10 is about 40 to 50 degrees by the action of the balance weight portion 12. Tilt. In this state, by moving the automatic lifting device 10 or the load 19 in a predetermined direction, as shown in FIG. That is, when the load 19 is grounded and the load of the load 19 is released, the entire automatic lifting device 10 is tilted and becomes a shape that is easy to come off in a horizontal state, and a shape that is easy to come off in a vertical state. The hanger 10 can be automatically removed.
Further, at the moment when the load of the load 19 is released and the inclination of the automatic lifting device 10 occurs, the lifting wire rope 21 and the automatic lifting device 10 are in a free open state, and the automatic suspension is performed by the inertial force at this time. The tool 10 moves in a direction away from the suspension ring 20, and the automatic suspension tool 10 is detached from the suspension ring 20. The raising / lowering wire rope 21 and the automatic lifting device 10 cause a swing, and in most cases, the eaves portion 13 does not enter the hanging ring 20 and is separated from the hanging ring 20. Therefore, it is possible to automatically perform the latching and the latching state of the load 19 provided with the suspension ring 20.

前記実施の形態においては、鉤部13の内側先部は直線状であったが、通常のフックのように屈曲させてもよい。また、鉤部13の内側掛止部に、吊り環20が嵌入する溝を設けてもよく、これによって、吊り環20が外れにくいという利点がある。
なお、荷に取付ける吊り環は円状のものだけでなく、例えば、逆U字状、逆三角状のいずれであってもよい。
In the above-described embodiment, the inner front portion of the collar portion 13 is linear, but may be bent like a normal hook. Moreover, you may provide the groove | channel in which the hanging ring 20 fits in the inner latch part of the collar part 13, and this has the advantage that the hanging ring 20 cannot remove easily.
The hanging ring attached to the load is not limited to a circular shape, and may be, for example, an inverted U shape or an inverted triangular shape.
